If you wish to use the original Makefile with no configuration, you can instead use: make -f Makefile.classic On a windows box, use one of the Makefiles in the win/ subdirectory, according to your compiler and environment. If you have MinGW or MinGW-w64 installed on your system (Msys or Cygwin, or as cross-compile environment on Linux or Darwin), then consider: make -f win/Makefile.mingw If you have VC++ installed on your system, then consider: cd win; nmake /f Makefile.msc If you have trouble, or you want to do something fancy, just look at Makefile.classic. There are 6 configuration options that are all well commented. Instead of editing the Makefile.classic, consider copying Makefile.classic to an alternative name such as "GNUMakefile", "BSDMakefile", or "makefile" and editing the copy. BUILDING OUTSIDE THE SOURCE TREE An out of source build is pretty easy: 1. Make and change to a new directory to do the builds in. 2. Run the "configure" script from this directory. 3. Type: "make" For example: mkdir build cd build ../configure make This will now keep all generated files separate from the maintained source code. -------------------------------------------------------------------------- Here are some notes on what is happening behind the scenes: * The configure script (if used) examines the options given and runs various tests with the C compiler to create Makefile from the Makefile.in template as well as autoconfig.h * The Makefile just sets up a few macros and then invokes the real makefile in src/main.mk. The src/main.mk makefile is automatically generated by a TCL script found at tools/makemake.tcl. Do not edit src/main.mk directly. Update tools/makemake.tcl and then rerun it. * The *.h header files are automatically generated using a program called "makeheaders". Source code to the makeheaders program is found in tools/makeheaders.c. Documentation is found in tools/makeheaders.html. * Most *.c source files are preprocessed using a program called "translate". The sources to translate are found in tools/translate.c. A header comment in tools/translate.c explains in detail what it does. * The tools/mkindex.c program generates some C code that implements static lookup tables. See the header comment in the source code for details on what it does. Additional information on the build process is available from http://fossil-scm.org/home/doc/trunk/www/makefile.wiki |

## STAGE 1: Build static Fossil binary
## ---------------------------------------------------------------------
### We aren't pinning to a more stable version of Alpine because we want
### to build with the latest tools and libraries available in case they
### fixed something that matters to us since the last build. Everything
### below depends on this layer, and so, alas, we toss this container's
### cache on Alpine's release schedule, roughly once a month.
FROM alpine:latest AS bld
WORKDIR /fsl
### Bake the basic Alpine Linux into a base layer so it only changes
### when the upstream image is updated or we change the package set.
RUN set -x \
&& apk update \
&& apk upgrade --no-cache \
&& apk add --no-cache \
gcc make \
linux-headers musl-dev \
openssl-dev openssl-libs-static \
zlib-dev zlib-static
### Build Fossil as a separate layer so we don't have to rebuild the
### Alpine environment for each iteration of Fossil's dev cycle.
###
### We must cope with a bizarre ADD misfeature here: it unpacks tarballs
### automatically when you give it a local file name but not if you give
### it a /tarball URL! It matters because we default to a URL in case
### you're building outside a Fossil checkout, but when building via the
### container-image target, we avoid a costly hit on fossil-scm.org
### by leveraging its DVCS nature via the "tarball" command and passing
### the resulting file's name in.

ARG FSLVER="trunk"

then mv $FSLSTB/src . ; \
else tar -xf src.tar.gz ; fi \
&& src/configure --static CFLAGS='-Os -s' $FSLCFG && make -j16
## ---------------------------------------------------------------------
## STAGE 2: Pare that back to the bare essentials.
## ---------------------------------------------------------------------
FROM busybox AS os
ARG UID=499
### Set up that base OS for our specific use without tying it to
### anything likely to change often. So long as the user leaves
### UID alone, this layer will be durable.

&& echo "fossil:x:${UID}:${UID}:User:/museum:/false" >> /e/passwd \
&& echo "fossil:x:${UID}:fossil" >> /e/group

This Makefile is used for # testing on an old PPC iBook. The use of this old platform helps to verify # Fossil and SQLite running on big-endian hardware. # # To build with this Makefile, run: # # make -f Makefile.osx-jaguar # # # This is the top-level makefile for Fossil when the build is occurring # on a unix platform. This works out-of-the-box on most unix platforms. # But you are free to vary some of the definitions if desired. # #### The toplevel directory of the source tree. Fossil can be built # in a directory that is separate from the source tree. Just change # the following to point from the build directory to the src/ folder. # SRCDIR = ./src #### The directory into which object code files should be written. # Having a "./" prefix in the value of this variable breaks our use of the # "makeheaders" tool when running make on the MinGW platform, apparently # due to some command line argument manipulation performed automatically # by the shell. # # OBJDIR = bld #### C Compiler and options for use in building executables that # will run on the platform that is doing the build. This is used # to compile code-generator programs as part of the build process. # See TCC below for the C compiler for building the finished binary. # BCC = cc BCCFLAGS = $(CFLAGS) #### The suffix to add to final executable file. When cross-compiling # to windows, make this ".exe". Otherwise leave it blank. # E = TCC = cc TCCFLAGS = $(CFLAGS) #### Tcl shell for use in running the fossil testsuite. If you do not # care about testing the end result, this can be blank. # TCLSH = tclsh # LIB = -lz LIB = compat/zlib/libz.a TCC += -g -O0 -DHAVE_AUTOCONFIG_H TCC += -Icompat/zlib TCC += -DSQLITE_WITHOUT_ZONEMALLOC TCC += -D_BSD_SOURCE=1 TCC += -DWITHOUT_ICONV TCC += -Dsocklen_t=int TCC += -DSQLITE_MAX_MMAP_SIZE=0 INSTALLDIR = $(DESTDIR)/usr/local/bin USE_SYSTEM_SQLITE = USE_LINENOISE = 1 # FOSSIL_ENABLE_TCL = @FOSSIL_ENABLE_TCL@ FOSSIL_ENABLE_TCL = 0 include $(SRCDIR)/main.mk distclean: clean rm -f autoconfig.h config.log Makefile |

Fossil was originally designed to support the [SQLite](https://sqlite.org) project but has been adopted by many other projects as well. Fossil is self-hosting at <https://fossil-scm.org>. If you are reading this on GitHub, then you are looking at a Git mirror of the self-hosting Fossil repository. The purpose of that mirror is to test and exercise Fossil's ability to export a Git mirror. Nobody much uses the GitHub mirror, except to verify that the mirror logic works. If you want to know more about Fossil, visit the official self-hosting site linked above. |

#
# Specifies configuration-time options which may be selected by the user

# of options specifications separated by newlines, as follows:
#
# A boolean option is of the form:
#
## name[=0|1] => "Description of this boolean option"
#
# The default is 'name=0', meaning that the option is disabled by default.
# If 'name=1' is used to make the option enabled by default, the description should reflect
# that with text like "Disable support for ...".
#
# An argument option (one which takes a parameter) is of one of the following forms:
#
## name:value => "Description of this option"
## name:value=default => "Description of this option with a default value"
## name:=value => "Description of this option with an optional value"
#
# If the 'name:value' form is used, the value must be provided with the option (as '--name=myvalue').
# If the 'name:value=default' form is used, the option has the given default value even if not
# specified by the user.
# If the 'name:=value' form is used, the value is optional and the given value is used
# if it is not provided.
#
# The description may contain '@default@', in which case it will be replaced with the default
# value for the option (taking into account defaults specified with 'options-defaults'.
#
# Undocumented options are also supported by omitting the '=> description'.
# These options are not displayed with '--help' and can be useful for internal options or as aliases.
#
# For example, '--disable-lfs' is an alias for '--disable=largefile':
#

#
# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.
# You can get the latest version of this script from:
# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support. The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.
# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.
# The "shellcheck disable" line above the timestamp inhibits complaints
# about features and limitations of the classic Bourne shell that were
# superseded or lifted in POSIX. However, this script identifies a wide
# variety of pre-POSIX systems that do not have POSIX shells at all, and
# even some reasonably current systems (Solaris 10 as case-in-point) still
# have a pre-POSIX /bin/sh.

# @synopsis:
#
# The 'tmake' module makes it easy to support the tmake build system.
#
# The following variables are set:
#
## CONFIGURED - to indicate that the project is configured
use system
options {}
define CONFIGURED
# @make-tmake-settings outfile patterns ...
#
# Examines all defined variables which match the given patterns (defaults to '*')
# and writes a tmake-compatible .conf file defining those variables.
# For example, if 'ABC' is '"3 monkeys"' and 'ABC' matches a pattern, then the file will include:
#
## define ABC {3 monkeys}
#
# If the file would be unchanged, it is not written.
#
# Typical usage is:
#
## make-tmake-settings [get-env BUILDDIR objdir]/settings.conf {[A-Z]*}

* (which may be " or {) up to but not including
* the space, semicolon, or bracket that
* terminates the word. NumComponents counts the
* total number of sub-tokens that make up the
* word. This includes, for example, sub-tokens
* of TCL_TOKEN_VARIABLE tokens.
* TCL_TOKEN_SIMPLE_WORD - This token is just like TCL_TOKEN_WORD except
* that the word is guaranteed to consist of a
* single TCL_TOKEN_TEXT sub-token.
* TCL_TOKEN_TEXT - The token describes a range of literal text
* that is part of a word. NumComponents is
* always 0.
* TCL_TOKEN_BS - The token describes a backslash sequence that
* must be collapsed. NumComponents is always 0.
* TCL_TOKEN_COMMAND - The token describes a command whose result
* must be substituted into the word. The token
* includes the enclosing brackets. NumComponents
* is always 0.
* TCL_TOKEN_VARIABLE - The token describes a variable substitution,
* including the dollar sign, variable name, and
* array index (if there is one) up through the
* right parentheses. NumComponents tells how
* many additional tokens follow to represent the
* variable name. The first token will be a
* TCL_TOKEN_TEXT token that describes the
* variable name. If the variable is an array
* reference then there will be one or more
* additional tokens, of type TCL_TOKEN_TEXT,
* TCL_TOKEN_BS, TCL_TOKEN_COMMAND, and
* TCL_TOKEN_VARIABLE, that describe the array
* index; numComponents counts the total number
* of nested tokens that make up the variable
* reference, including sub-tokens of
* TCL_TOKEN_VARIABLE tokens.
* TCL_TOKEN_SUB_EXPR - The token describes one subexpression of an
* expression, from the first non-blank character
* of the subexpression up to but not including
* the space, brace, or bracket that terminates
* the subexpression. NumComponents counts the
* total number of following subtokens that make
* up the subexpression; this includes all
* subtokens for any nested TCL_TOKEN_SUB_EXPR
* tokens. For example, a numeric value used as a
* primitive operand is described by a
* TCL_TOKEN_SUB_EXPR token followed by a
* TCL_TOKEN_TEXT token. A binary subexpression
* is described by a TCL_TOKEN_SUB_EXPR token
* followed by the TCL_TOKEN_OPERATOR token for
* the operator, then TCL_TOKEN_SUB_EXPR tokens
* for the left then the right operands.
* TCL_TOKEN_OPERATOR - The token describes one expression operator.
* An operator might be the name of a math
* function such as "abs". A TCL_TOKEN_OPERATOR
* token is always preceeded by one
* TCL_TOKEN_SUB_EXPR token for the operator's
* subexpression, and is followed by zero or more
* TCL_TOKEN_SUB_EXPR tokens for the operator's
* operands. NumComponents is always 0.
* TCL_TOKEN_EXPAND_WORD - This token is just like TCL_TOKEN_WORD except
* that it marks a word that began with the
* literal character prefix "{*}". This word is
* marked to be expanded - that is, broken into
* words after substitution is complete.

Frequently Asked Questions about zlib
If your question is not there, please check the zlib home page
http://zlib.net/ which may have more recent information.
The latest zlib FAQ is at http://zlib.net/zlib_faq.html
1. Is zlib Y2K-compliant?
Yes. zlib doesn't handle dates.
2. Where can I get a Windows DLL version?
The zlib sources can be compiled without change to produce a DLL. See the
file win32/DLL_FAQ.txt in the zlib distribution.
3. Where can I get a Visual Basic interface to zlib?
See
* http://marknelson.us/1997/01/01/zlib-engine/
* win32/DLL_FAQ.txt in the zlib distribution
4. compress() returns Z_BUF_ERROR.
Make sure that before the call of compress(), the length of the compressed
buffer is equal to the available size of the compressed buffer and not
zero. For Visual Basic, check that this parameter is passed by reference
("as any"), not by value ("as long").
5. deflate() or inflate() returns Z_BUF_ERROR.
Before making the call, make sure that avail_in and avail_out are not zero.
When setting the parameter flush equal to Z_FINISH, also make sure that
avail_out is big enough to allow processing all pending input. Note that a
Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
made with more input or output space. A Z_BUF_ERROR may in fact be
unavoidable depending on how the functions are used, since it is not
possible to tell whether or not there is more output pending when
strm.avail_out returns with zero. See http://zlib.net/zlib_how.html for a
heavily annotated example.
6. Where's the zlib documentation (man pages, etc.)?
It's in zlib.h . Examples of zlib usage are in the files test/example.c
and test/minigzip.c, with more in examples/ .
7. Why don't you use GNU autoconf or libtool or ...?
Because we would like to keep zlib as a very small and simple package.
zlib is rather portable and doesn't need much configuration.
8. I found a bug in zlib.
Most of the time, such problems are due to an incorrect usage of zlib.
Please try to reproduce the problem with a small program and send the
corresponding source to us at zlib@gzip.org . Do not send multi-megabyte
data files without prior agreement.
9. Why do I get "undefined reference to gzputc"?
If "make test" produces something like
example.o(.text+0x154): undefined reference to `gzputc'
check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
/usr/X11R6/lib. Remove any old versions, then do "make install".
10. I need a Delphi interface to zlib.
See the contrib/delphi directory in the zlib distribution.
11. Can zlib handle .zip archives?
Not by itself, no. See the directory contrib/minizip in the zlib
distribution.
12. Can zlib handle .Z files?
No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
the code of uncompress on your own.
13. How can I make a Unix shared library?
By default a shared (and a static) library is built for Unix. So:
make distclean
./configure
make
14. How do I install a shared zlib library on Unix?
After the above, then:
make install
However, many flavors of Unix come with a shared zlib already installed.
Before going to the trouble of compiling a shared version of zlib and
trying to install it, you may want to check if it's already there! If you
can #include <zlib.h>, it's there. The -lz option will probably link to
it. You can check the version at the top of zlib.h or with the
ZLIB_VERSION symbol defined in zlib.h .
15. I have a question about OttoPDF.
We are not the authors of OttoPDF. The real author is on the OttoPDF web
site: Joel Hainley, jhainley@myndkryme.com.
16. Can zlib decode Flate data in an Adobe PDF file?
Yes. See http://www.pdflib.com/ . To modify PDF forms, see
http://sourceforge.net/projects/acroformtool/ .
17. Why am I getting this "register_frame_info not found" error on Solaris?
After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
generates an error such as:
ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
symbol __register_frame_info: referenced symbol not found
The symbol __register_frame_info is not part of zlib, it is generated by
the C compiler (cc or gcc). You must recompile applications using zlib
which have this problem. This problem is specific to Solaris. See
http://www.sunfreeware.com for Solaris versions of zlib and applications
using zlib.
18. Why does gzip give an error on a file I make with compress/deflate?
The compress and deflate functions produce data in the zlib format, which
is different and incompatible with the gzip format. The gz* functions in
zlib on the other hand use the gzip format. Both the zlib and gzip formats
use the same compressed data format internally, but have different headers
and trailers around the compressed data.
19. Ok, so why are there two different formats?
The gzip format was designed to retain the directory information about a
single file, such as the name and last modification date. The zlib format
on the other hand was designed for in-memory and communication channel
applications, and has a much more compact header and trailer and uses a
faster integrity check than gzip.
20. Well that's nice, but how do I make a gzip file in memory?
You can request that deflate write the gzip format instead of the zlib
format using deflateInit2(). You can also request that inflate decode the
gzip format using inflateInit2(). Read zlib.h for more details.
21. Is zlib thread-safe?
Yes. However any library routines that zlib uses and any application-
provided memory allocation routines must also be thread-safe. zlib's gz*
functions use stdio library routines, and most of zlib's functions use the
library memory allocation routines by default. zlib's *Init* functions
allow for the application to provide custom memory allocation routines.
Of course, you should only operate on any given zlib or gzip stream from a
single thread at a time.
22. Can I use zlib in my commercial application?
Yes. Please read the license in zlib.h.
23. Is zlib under the GNU license?
No. Please read the license in zlib.h.
24. The license says that altered source versions must be "plainly marked". So
what exactly do I need to do to meet that requirement?
You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
particular, the final version number needs to be changed to "f", and an
identification string should be appended to ZLIB_VERSION. Version numbers
x.x.x.f are reserved for modifications to zlib by others than the zlib
maintainers. For example, if the version of the base zlib you are altering
is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
update the version strings in deflate.c and inftrees.c.
For altered source distributions, you should also note the origin and
nature of the changes in zlib.h, as well as in ChangeLog and README, along
with the dates of the alterations. The origin should include at least your
name (or your company's name), and an email address to contact for help or
issues with the library.
Note that distributing a compiled zlib library along with zlib.h and
zconf.h is also a source distribution, and so you should change
ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
in zlib.h as you would for a full source distribution.
25. Will zlib work on a big-endian or little-endian architecture, and can I
exchange compressed data between them?
Yes and yes.
26. Will zlib work on a 64-bit machine?
Yes. It has been tested on 64-bit machines, and has no dependence on any
data types being limited to 32-bits in length. If you have any
difficulties, please provide a complete problem report to zlib@gzip.org
27. Will zlib decompress data from the PKWare Data Compression Library?
No. The PKWare DCL uses a completely different compressed data format than
does PKZIP and zlib. However, you can look in zlib's contrib/blast
directory for a possible solution to your problem.
28. Can I access data randomly in a compressed stream?
No, not without some preparation. If when compressing you periodically use
Z_FULL_FLUSH, carefully write all the pending data at those points, and
keep an index of those locations, then you can start decompression at those
points. You have to be careful to not use Z_FULL_FLUSH too often, since it
can significantly degrade compression. Alternatively, you can scan a
deflate stream once to generate an index, and then use that index for
random access. See examples/zran.c .
29. Does zlib work on MVS, OS/390, CICS, etc.?
It has in the past, but we have not heard of any recent evidence. There
were working ports of zlib 1.1.4 to MVS, but those links no longer work.
If you know of recent, successful applications of zlib on these operating
systems, please let us know. Thanks.
30. Is there some simpler, easier to read version of inflate I can look at to
understand the deflate format?
First off, you should read RFC 1951. Second, yes. Look in zlib's
contrib/puff directory.
31. Does zlib infringe on any patents?
As far as we know, no. In fact, that was originally the whole point behind
zlib. Look here for some more information:
http://www.gzip.org/#faq11
32. Can zlib work with greater than 4 GB of data?
Yes. inflate() and deflate() will process any amount of data correctly.
Each call of inflate() or deflate() is limited to input and output chunks
of the maximum value that can be stored in the compiler's "unsigned int"
type, but there is no limit to the number of chunks. Note however that the
strm.total_in and strm_total_out counters may be limited to 4 GB. These
counters are provided as a convenience and are not used internally by
inflate() or deflate(). The application can easily set up its own counters
updated after each call of inflate() or deflate() to count beyond 4 GB.
compress() and uncompress() may be limited to 4 GB, since they operate in a
single call. gzseek() and gztell() may be limited to 4 GB depending on how
zlib is compiled. See the zlibCompileFlags() function in zlib.h.
The word "may" appears several times above since there is a 4 GB limit only
if the compiler's "long" type is 32 bits. If the compiler's "long" type is
64 bits, then the limit is 16 exabytes.
33. Does zlib have any security vulnerabilities?
The only one that we are aware of is potentially in gzprintf(). If zlib is
compiled to use sprintf() or vsprintf(), then there is no protection
against a buffer overflow of an 8K string space (or other value as set by
gzbuffer()), other than the caller of gzprintf() assuring that the output
will not exceed 8K. On the other hand, if zlib is compiled to use
snprintf() or vsnprintf(), which should normally be the case, then there is
no vulnerability. The ./configure script will display warnings if an
insecure variation of sprintf() will be used by gzprintf(). Also the
zlibCompileFlags() function will return information on what variant of
sprintf() is used by gzprintf().
If you don't have snprintf() or vsnprintf() and would like one, you can
find a portable implementation here:
http://www.ijs.si/software/snprintf/
Note that you should be using the most recent version of zlib. Versions
1.1.3 and before were subject to a double-free vulnerability, and versions
1.2.1 and 1.2.2 were subject to an access exception when decompressing
invalid compressed data.
34. Is there a Java version of zlib?
Probably what you want is to use zlib in Java. zlib is already included
as part of the Java SDK in the java.util.zip package. If you really want
a version of zlib written in the Java language, look on the zlib home
page for links: http://zlib.net/ .
35. I get this or that compiler or source-code scanner warning when I crank it
up to maximally-pedantic. Can't you guys write proper code?
Many years ago, we gave up attempting to avoid warnings on every compiler
in the universe. It just got to be a waste of time, and some compilers
were downright silly as well as contradicted each other. So now, we simply
make sure that the code always works.
36. Valgrind (or some similar memory access checker) says that deflate is
performing a conditional jump that depends on an uninitialized value.
Isn't that a bug?
No. That is intentional for performance reasons, and the output of deflate
is not affected. This only started showing up recently since zlib 1.2.x
uses malloc() by default for allocations, whereas earlier versions used
calloc(), which zeros out the allocated memory. Even though the code was
correct, versions 1.2.4 and later was changed to not stimulate these
checkers.
37. Will zlib read the (insert any ancient or arcane format here) compressed
data format?
Probably not. Look in the comp.compression FAQ for pointers to various
formats and associated software.
38. How can I encrypt/decrypt zip files with zlib?
zlib doesn't support encryption. The original PKZIP encryption is very
weak and can be broken with freely available programs. To get strong
encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
compression. For PKZIP compatible "encryption", look at
http://www.info-zip.org/
39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
"gzip" is the gzip format, and "deflate" is the zlib format. They should
probably have called the second one "zlib" instead to avoid confusion with
the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
correctly points to the zlib specification in RFC 1950 for the "deflate"
transfer encoding, there have been reports of servers and browsers that
incorrectly produce or expect raw deflate data per the deflate
specification in RFC 1951, most notably Microsoft. So even though the
"deflate" transfer encoding using the zlib format would be the more
efficient approach (and in fact exactly what the zlib format was designed
for), using the "gzip" transfer encoding is probably more reliable due to
an unfortunate choice of name on the part of the HTTP 1.1 authors.
Bottom line: use the gzip format for HTTP 1.1 encoding.
40. Does zlib support the new "Deflate64" format introduced by PKWare?
No. PKWare has apparently decided to keep that format proprietary, since
they have not documented it as they have previous compression formats. In
any case, the compression improvements are so modest compared to other more
modern approaches, that it's not worth the effort to implement.
41. I'm having a problem with the zip functions in zlib, can you help?
There are no zip functions in zlib. You are probably using minizip by
Giles Vollant, which is found in the contrib directory of zlib. It is not
part of zlib. In fact none of the stuff in contrib is part of zlib. The
files in there are not supported by the zlib authors. You need to contact
the authors of the respective contribution for help.
42. The match.asm code in contrib is under the GNU General Public License.
Since it's part of zlib, doesn't that mean that all of zlib falls under the
GNU GPL?
No. The files in contrib are not part of zlib. They were contributed by
other authors and are provided as a convenience to the user within the zlib
distribution. Each item in contrib has its own license.
43. Is zlib subject to export controls? What is its ECCN?
zlib is not subject to export controls, and so is classified as EAR99.
44. Can you please sign these lengthy legal documents and fax them back to us
so that we can use your software in our product?
No. Go away. Shoo.

ZLIB DATA COMPRESSION LIBRARY
zlib 1.3.1 is a general purpose data compression library. All the code is
thread safe. The data format used by the zlib library is described by RFCs
(Request for Comments) 1950 to 1952 in the files
http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
rfc1952 (gzip format).
All functions of the compression library are documented in the file zlib.h
(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
of the library is given in the file test/example.c which also tests that
the library is working correctly. Another example is given in the file
test/minigzip.c. The compression library itself is composed of all source
files in the root directory.
To compile all files and run the test program, follow the instructions given at
the top of Makefile.in. In short "./configure; make test", and if that goes
well, "make install" should work for most flavors of Unix. For Windows, use
one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
make_vms.com.
Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
<info@winimage.com> for the Windows DLL version. The zlib home page is
http://zlib.net/ . Before reporting a problem, please check this site to
verify that you have the latest version of zlib; otherwise get the latest
version and check whether the problem still exists or not.
PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
issue of Dr. Dobb's Journal; a copy of the article is available at
https://marknelson.us/posts/1997/01/01/zlib-engine.html .
The changes made in version 1.3.1 are documented in the file ChangeLog.
Unsupported third party contributions are provided in directory contrib/ .
zlib is available in Java using the java.util.zip package. Follow the API
Documentation link at: https://docs.oracle.com/search/?q=java.util.zip .
A Perl interface to zlib and bzip2 written by Paul Marquess <pmqs@cpan.org>
can be found at https://github.com/pmqs/IO-Compress .
A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
available in Python 1.5 and later versions, see
http://docs.python.org/library/zlib.html .
zlib is built into tcl: http://wiki.tcl.tk/4610 .
An experimental package to read and write files in .zip format, written on top
of zlib by Gilles Vollant <info@winimage.com>, is available in the
contrib/minizip directory of zlib.
Notes for some targets:
- For Windows DLL versions, please see win32/DLL_FAQ.txt
- For 64-bit Irix, deflate.c must be compiled without any optimization. With
-O, one libpng test fails. The test works in 32 bit mode (with the -n32
compiler flag). The compiler bug has been reported to SGI.
- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
when compiled with cc.
- On Digital Unix 4.0D (formerly OSF/1) on AlphaServer, the cc option -std1 is
necessary to get gzprintf working correctly. This is done by configure.
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
other compilers. Use "make test" to check your compiler.
- gzdopen is not supported on RISCOS or BEOS.
- For PalmOs, see http://palmzlib.sourceforge.net/
Acknowledgments:
The deflate format used by zlib was defined by Phil Katz. The deflate and
zlib specifications were written by L. Peter Deutsch. Thanks to all the
people who reported problems and suggested various improvements in zlib; they
are too numerous to cite here.

# If you want to build just a static library, use: ./configure --static
#
# To impose specific compiler or flags or install directory, use for example:
# prefix=$HOME CC=cc CFLAGS="-O4" ./configure
# or for csh/tcsh users:
# (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
# Incorrect settings of CC or CFLAGS may prevent creating a shared library.
# If you have problems, try without defining CC and CFLAGS before reporting
# an error.

* Copyright (C) 2003, 2012, 2013 Mark Adler
* For conditions of distribution and use, see copyright notice in blast.h

*
* blast.c decompresses data compressed by the PKWare Compression Library.
* This function provides functionality similar to the explode() function of
* the PKWare library, hence the name "blast".
*
* This decompressor is based on the excellent format description provided by
* Ben Rudiak-Gould in comp.compression on August 13, 2001. Interestingly, the
* example Ben provided in the post is incorrect. The distance 110001 should
* instead be 111000. When corrected, the example byte stream becomes:
*
* 00 04 82 24 25 8f 80 7f
*
* which decompresses to "AIAIAIAIAIAIA" (without the quotes).
*/
/*
* Change history:
*
* 1.0 12 Feb 2003 - First version
* 1.1 16 Feb 2003 - Fixed distance check for > 4 GB uncompressed data
* 1.2 24 Oct 2012 - Add note about using binary mode in stdio
* - Fix comparisons of differently signed integers
* 1.3 24 Aug 2013 - Return unused input from blast()

* - Compressed data is a combination of literals and length/distance pairs
* terminated by an end code. Literals are either Huffman coded or
* uncoded bytes. A length/distance pair is a coded length followed by a
* coded distance to represent a string that occurs earlier in the
* uncompressed data that occurs again at the current location.
*
* - A bit preceding a literal or length/distance pair indicates which comes
* next, 0 for literals, 1 for length/distance.
*
* - If literals are uncoded, then the next eight bits are the literal, in the
* normal bit order in the stream, i.e. no bit-reversal is needed. Similarly,
* no bit reversal is needed for either the length extra bits or the distance
* extra bits.
*
* - Literal bytes are simply written to the output. A length/distance pair is
* an instruction to copy previously uncompressed bytes to the output. The
* copy is from distance bytes back in the output stream, copying for length
* bytes.
*
* - Distances pointing before the beginning of the output data are not
* permitted.
*
* - Overlapped copies, where the length is greater than the distance, are
* allowed and common. For example, a distance of one and a length of 518
* simply copies the last byte 518 times. A distance of four and a length of
* twelve copies the last four bytes three times. A simple forward copy
* ignoring whether the length is greater than the distance or not implements
* this correctly.

* output space, then a positive error is returned.
*
* The input function is invoked: len = infun(how, &buf), where buf is set by
* infun() to point to the input buffer, and infun() returns the number of
* available bytes there. If infun() returns zero, then blast() returns with
* an input error. (blast() only asks for input if it needs it.) inhow is for
* use by the application to pass an input descriptor to infun(), if desired.
*
* If left and in are not NULL and *left is not zero when blast() is called,
* then the *left bytes at *in are consumed for input before infun() is used.
*
* The output function is invoked: err = outfun(how, buf, len), where the bytes
* to be written are buf[0..len-1]. If err is not zero, then blast() returns
* with an output error. outfun() is always called with len <= 4096. outhow
* is for use by the application to pass an output descriptor to outfun(), if
* desired.
*
* If there is any unused input, *left is set to the number of bytes that were
* read and *in points to them. Otherwise *left is set to zero and *in is set
* to NULL. If left or in are NULL, then they are not set.
*
* The return codes are:
*
* 2: ran out of input before completing decompression
* 1: output error before completing decompression
* 0: successful decompression
* -1: literal flag not zero or one
* -2: dictionary size not in 4..6
* -3: distance is too far back
*
* At the bottom of blast.c is an example program that uses blast() that can be
* compiled to produce a command-line decompression filter by defining TEST.

{ TCompressionStream compresses data on the fly as data is written to it, and
stores the compressed data to another stream.
TCompressionStream is write-only and strictly sequential. Reading from the
stream will raise an exception. Using Seek to move the stream pointer
will raise an exception.
Output data is cached internally, written to the output stream only when
the internal output buffer is full. All pending output data is flushed
when the stream is destroyed.
The Position property returns the number of uncompressed bytes of
data that have been written to the stream so far.
CompressionRate returns the on-the-fly percentage by which the original
data has been compressed: (1 - (CompressedBytes / UncompressedBytes)) * 100
If raw data size = 100 and compressed data size = 25, the CompressionRate
is 75%
The OnProgress event is called each time the output buffer is filled and
written to the output stream. This is useful for updating a progress
indicator when you are writing a large chunk of data to the compression
stream in a single call.}

{ TDecompressionStream decompresses data on the fly as data is read from it.
Compressed data comes from a separate source stream. TDecompressionStream
is read-only and unidirectional; you can seek forward in the stream, but not
backwards. The special case of setting the stream position to zero is
allowed. Seeking forward decompresses data until the requested position in
the uncompressed data has been reached. Seeking backwards, seeking relative
to the end of the stream, requesting the size of the stream, and writing to
the stream will raise an exception.
The Position property returns the number of bytes of uncompressed data that
have been read from the stream so far.
The OnProgress event is called each time the internal input buffer of
compressed data is exhausted and the next block is read from the input stream.
This is useful for updating a progress indicator when you are reading a
large chunk of data from the decompression stream in a single call.}

Overview
========
This directory contains an update to the ZLib interface unit,
distributed by Borland as a Delphi supplemental component.
The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
and is based on zlib version 1.0.4. There are a series of bugs
and security problems associated with that old zlib version, and
we recommend the users to update their ZLib unit.
Summary of modifications
========================
- Improved makefile, adapted to zlib version 1.2.1.
- Some field types from TZStreamRec are changed from Integer to
Longint, for consistency with the zlib.h header, and for 64-bit
readiness.
- The zlib_version constant is updated.
- The new Z_RLE strategy has its corresponding symbolic constant.
- The allocation and deallocation functions and function types
(TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
and _malloc and _free are added as C RTL stubs. As a result,
the original C sources of zlib can be compiled out of the box,
and linked to the ZLib unit.
Suggestions for improvements
============================
Currently, the ZLib unit provides only a limited wrapper around
the zlib library, and much of the original zlib functionality is
missing. Handling compressed file formats like ZIP/GZIP or PNG
cannot be implemented without having this functionality.
Applications that handle these formats are either using their own,
duplicated code, or not using the ZLib unit at all.
Here are a few suggestions:
- Checksum class wrappers around adler32() and crc32(), similar
to the Java classes that implement the java.util.zip.Checksum
interface.
- The ability to read and write raw deflate streams, without the
zlib stream header and trailer. Raw deflate streams are used
in the ZIP file format.
- The ability to read and write gzip streams, used in the GZIP
file format, and normally produced by the gzip program.
- The ability to select a different compression strategy, useful
to PNG and MNG image compression, and to multimedia compression
in general. Besides the compression level
TCompressionLevel = (clNone, clFastest, clDefault, clMax);
which, in fact, could have used the 'z' prefix and avoided
TColor-like symbols
TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax);
there could be a compression strategy
TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle);
- ZIP and GZIP stream handling via TStreams.

This directory contains a .Net wrapper class library for the ZLib1.dll
The wrapper includes support for inflating/deflating memory buffers,
.Net streaming wrappers for the gz streams part of zlib, and wrappers
for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.
Directory structure:
--------------------
LICENSE_1_0.txt - License file.
readme.txt - This file.
DotZLib.chm - Class library documentation
DotZLib.build - NAnt build file
DotZLib.sln - Microsoft Visual Studio 2003 solution file
DotZLib\*.cs - Source files for the class library
Unit tests:
-----------
The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
To include unit tests in the build, define nunit before building.
Build instructions:
-------------------
1. Using Visual Studio.Net 2003:
Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
you are building the release or debug version of the library. Check
DotZLib/UnitTests.cs for instructions on how to include unit tests in the
build.
2. Using NAnt:
Open a command prompt with access to the build environment and run nant
in the same directory as the DotZLib.build file.
You can define 2 properties on the nant command-line to control the build:
debug={true|false} to toggle between release/debug builds (default=true).
nunit={true|false} to include or exclude unit tests (default=true).
Also the target clean will remove binaries.
Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
or ./DotZLib/bin/debug, depending on whether you are building the release
or debug version of the library.
Examples:
nant -D:debug=false -D:nunit=false
will build a release mode version of the library without unit tests.
nant
will build a debug version of the library with unit tests
nant clean
will remove all previously built files.

strm provides the memory allocation functions and window buffer on input,
and provides information on the unused input on return. For Z_DATA_ERROR
returns, strm will also provide an error message.
in() and out() are the call-back input and output functions. When
inflateBack() needs more input, it calls in(). When inflateBack() has
filled the window with output, or when it completes with data in the
window, it calls out() to write out the data. The application must not
change the provided input until in() is called again or inflateBack()
returns. The application must not change the window/output buffer until
inflateBack() returns.
in() and out() are called with a descriptor parameter provided in the
inflateBack() call. This parameter can be a structure that provides the
information required to do the read or write, as well as accumulated
information on the input and output such as totals and check values.
in() should return zero on failure. out() should return non-zero on
failure. If either in() or out() fails, than inflateBack() returns a
Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
was in() or out() that caused in the error. Otherwise, inflateBack()
returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
error, or Z_MEM_ERROR if it could not allocate memory for the state.
inflateBack() can also return Z_STREAM_ERROR if the input parameters
are not correct, i.e. strm is Z_NULL or the state was not initialized.

* This should be compiled with zlib, since it uses zutil.h and zutil.o.
* This code has not yet been tested on 16-bit architectures. See the
* comments in zlib.h for inflateBack() usage. These functions are used
* identically, except that there is no windowBits parameter, and a 64K
* window must be provided. Also if int's are 16 bits, then a zero for
* the third parameter of the "out" function actually means 65536UL.
* zlib.h must be included before this header file.

Process a set of code lengths to create a canonical Huffman code. The
code lengths are lens[0..codes-1]. Each length corresponds to the
symbols 0..codes-1. The Huffman code is generated by first sorting the
symbols by length from short to long, and retaining the symbol order
for codes with equal lengths. Then the code starts with all zero bits
for the first code of the shortest length, and the codes are integer
increments for the same length, and zeros are appended as the length
increases. For the deflate format, these bits are stored backwards
from their more natural integer increment ordering, and so when the
decoding tables are built in the large loop below, the integer codes
are incremented backwards.
This routine assumes, but does not check, that all of the entries in
lens[] are in the range 0..MAXBITS. The caller must assure this.
1..MAXBITS is interpreted as that code length. zero means that that
symbol does not occur in this code.
The codes are sorted by computing a count of codes for each length,
creating from that a table of starting indices for each length in the
sorted table, and then entering the symbols in order in the sorted
table. The sorted table is work[], with that space being provided by
the caller.
The length counts are used for other purposes as well, i.e. finding
the minimum and maximum length codes, determining if there are any
codes at all, checking for a valid set of lengths, and looking ahead
at length counts to determine sub-table sizes when building the
decoding tables.

Create and fill in decoding tables. In this loop, the table being
filled is at next and has curr index bits. The code being used is huff
with length len. That code is converted to an index by dropping drop
bits off of the bottom. For codes where len is less than drop + curr,
those top drop + curr - len bits are incremented through all values to
fill the table with replicated entries.
root is the number of index bits for the root table. When len exceeds
root, sub-tables are created pointed to by the root entry with an index
of the low root bits of huff. This is saved in low to check for when a
new sub-table should be started. drop is zero when the root table is
being filled, and drop is root when sub-tables are being filled.
When a new sub-table is needed, it is necessary to look ahead in the
code lengths to determine what size sub-table is needed. The length
counts are used for this, and so count[] is decremented as codes are
entered in the tables.
used keeps track of how many table entries have been allocated from the
provided *table space. It is checked for LENS and DIST tables against
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
the initial root table size constants. See the comments in inftree9.h
for more information.
sym increments through all symbols, and the loop terminates when
all codes of length max, i.e. all codes, have been processed. This
routine permits incomplete codes, so another loop after this one fills
in the rest of the decoding tables with invalid code markers.

These classes provide a C++ stream interface to the zlib library. It allows you
to do things like:
gzofstream outf("blah.gz");
outf << "These go into the gzip file " << 123 << endl;
It does this by deriving a specialized stream buffer for gzipped files, which is
the way Stroustrup would have done it. :->
The gzifstream and gzofstream classes were originally written by Kevin Ruland
and made available in the zlib contrib/iostream directory. The older version still
compiles under gcc 2.xx, but not under gcc 3.xx, which sparked the development of
this version.
The new classes are as standard-compliant as possible, closely following the
approach of the standard library's fstream classes. It compiles under gcc versions
3.2 and 3.3, but not under gcc 2.xx. This is mainly due to changes in the standard
library naming scheme. The new version of gzifstream/gzofstream/gzfilebuf differs
from the previous one in the following respects:
- added showmanyc
- added setbuf, with support for unbuffered output via setbuf(0,0)
- a few bug fixes of stream behavior
- gzipped output file opened with default compression level instead of maximum level
- setcompressionlevel()/strategy() members replaced by single setcompression()
The code is provided "as is", with the permission to use, copy, modify, distribute
and sell it for any purpose without fee.

MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
Introduction
---------------------
MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
All possible work was done for compatibility.
Background
---------------------
When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64
support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
That was used as a starting point. And after that ZIP64 support was added to zip.c
some refactoring and code cleanup was also done.
Changed from MiniZip 1.0 to MiniZip 1.1
---------------------------------------
* Added ZIP64 support for unzip ( by Even Rouault )
* Added ZIP64 support for zip ( by Mathias Svensson )
* Reverted some changed that Even Rouault did.
* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
* Added BZIP Compress method for zip
* Did some refactoring and code cleanup

Notes.
* To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

/* crypt.h -- base code for crypt/uncrypt ZIPfile
Version 1.01e, February 12th, 2005
Copyright (C) 1998-2005 Gilles Vollant
This code is a modified version of crypting code in Infozip distribution
The encryption/decryption parts of this source code (as opposed to the
non-echoing password parts) were originally written in Europe. The
whole source package can be freely distributed, including from the USA.
(Prior to January 2000, re-export from the US was a violation of US law.)
This encryption code is a direct transcription of the algorithm from
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
file (appnote.txt) is distributed with the PKZIP program (even in the
version without encryption capabilities).
If you don't need crypting in your application, just define symbols
NOCRYPT and NOUNCRYPT.
This code support the "Traditional PKWARE Encryption".
The new AES encryption added on Zip format by Winzip (see the page
http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
Encryption is not supported.

Modifications for Zip64 support
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
For more info read MiniZip_info.txt
Changes
Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
More if/def section may be needed to support other platforms
Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
(but you should use iowin32.c for windows instead)

It was written as a demonstration of the .IR zlib (3) library and therefore lack many of the features of the .IR unzip (1) program. .SH OPTIONS A number of options are supported. With the exception of .BI \-d\ tempdir these must be supplied before any other arguments and are: .TP .BI \-l\ ,\ \-\-v List the files in the archive without extracting them. .TP .B \-o Overwrite files without prompting for confirmation. .TP .B \-x Extract files (default). .PP The .I zipfile argument is the name of the archive to process. The next argument can be used to specify a single file to extract from the archive. Lastly, the following option can be specified at the end of the command-line: .TP .BI \-d\ tempdir Extract the archive in the directory .I tempdir rather than the current directory. .SH SEE ALSO .BR minizip (1), .BR zlib (3), .BR unzip (1). .SH AUTHOR This program was written by Gilles Vollant. This manual page was written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option was added by Dirk Eddelbuettel <edd@debian.org>. |

/* unzip.c -- IO for uncompress .zip files using zlib
Version 1.1, February 14h, 2010
part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
Modifications of Unzip for Zip64
Copyright (C) 2007-2008 Even Rouault
Modifications for Zip64 support on both zip and unzip
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
For more info read MiniZip_info.txt
------------------------------------------------------------------------------------
Decryption code comes from crypt.c by Info-ZIP but has been greatly reduced in terms of
compatibility with older software. The following is from the original crypt.c.
Code woven in by Terry Thorsen 1/2003.
Copyright (c) 1990-2000 Info-ZIP. All rights reserved.
See the accompanying file LICENSE, version 2000-Apr-09 or later
(the contents of which are also included in zip.h) for terms of use.
If, for some reason, all these files are missing, the Info-ZIP license
also may be found at: ftp://ftp.info-zip.org/pub/infozip/license.html
crypt.c (full version) by Info-ZIP. Last revised: [see crypt.h]
The encryption/decryption parts of this source code (as opposed to the
non-echoing password parts) were originally written in Europe. The
whole source package can be freely distributed, including from the USA.
(Prior to January 2000, re-export from the US was a violation of US law.)
This encryption code is a direct transcription of the algorithm from
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
file (appnote.txt) is distributed with the PKZIP program (even in the
version without encryption capabilities).
------------------------------------------------------------------------------------
Changes in unzip.c
2007-2008 - Even Rouault - Addition of cpl_unzGetCurrentFileZStreamPos
2007-2008 - Even Rouault - Decoration of symbol names unz* -> cpl_unz*
2007-2008 - Even Rouault - Remove old C style function prototypes
2007-2008 - Even Rouault - Add unzip support for ZIP64
Copyright (C) 2007-2008 Even Rouault
Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again).
Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
should only read the compressed/uncompressed size from the Zip64 format if
the size from normal header was 0xFFFFFFFF
Oct-2009 - Mathias Svensson - Applied some bug fixes from patches received from Gilles Vollant
Oct-2009 - Mathias Svensson - Applied support to unzip files with compression method BZIP2 (bzip2 lib is required)
Patch created by Daniel Borca
Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

/* zip.c -- IO on .zip files using zlib
Version 1.1, February 14h, 2010
part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
Modifications for Zip64 support
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
For more info read MiniZip_info.txt
Changes
Oct-2009 - Mathias Svensson - Remove old C style function prototypes
Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
It is used when recreating zip archive with RAW when deleting items from a zip.
ZIP64 data is automatically added to items that needs it, and existing ZIP64 data need to be removed.
Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

This directory contains a Pascal (Delphi, Kylix) interface to the
zlib data compression library.

Compatibility notes
===================
- Although the name "zlib" would have been more normal for the
zlibpas unit, this name is already taken by Borland's ZLib unit.
This is somehow unfortunate, because that unit is not a genuine
interface to the full-fledged zlib functionality, but a suite of
class wrappers around zlib streams. Other essential features,
such as checksums, are missing.
It would have been more appropriate for that unit to have a name
like "ZStreams", or something similar.
- The C and zlib-supplied types int, uInt, long, uLong, etc. are
translated directly into Pascal types of similar sizes (Integer,
LongInt, etc.), to avoid namespace pollution. In particular,
there is no conversion of unsigned int into a Pascal unsigned
integer. The Word type is non-portable and has the same size
(16 bits) both in a 16-bit and in a 32-bit environment, unlike
Integer. Even if there is a 32-bit Cardinal type, there is no
real need for unsigned int in zlib under a 32-bit environment.
- Except for the callbacks, the zlib function interfaces are
assuming the calling convention normally used in Pascal
(__pascal for DOS and Windows16, __fastcall for Windows32).
Since the cdecl keyword is used, the old Turbo Pascal does
not work with this interface.
- The gz* function interfaces are not translated, to avoid
interfacing problems with the C runtime library. Besides,
gzprintf(gzFile file, const char *format, ...)
cannot be translated into Pascal.

Puff -- A Simple Inflate
3 Mar 2003
Mark Adler
madler@alumni.caltech.edu
What this is --
puff.c provides the routine puff() to decompress the deflate data format. It
does so more slowly than zlib, but the code is about one-fifth the size of the
inflate code in zlib, and written to be very easy to read.
Why I wrote this --
puff.c was written to document the deflate format unambiguously, by virtue of
being working C code. It is meant to supplement RFC 1951, which formally
describes the deflate format. I have received many questions on details of the
deflate format, and I hope that reading this code will answer those questions.
puff.c is heavily commented with details of the deflate format, especially
those little nooks and cranies of the format that might not be obvious from a
specification.
puff.c may also be useful in applications where code size or memory usage is a
very limited resource, and speed is not as important.
How to use it --
Well, most likely you should just be reading puff.c and using zlib for actual
applications, but if you must ...
Include puff.h in your code, which provides this prototype:
int puff(unsigned char *dest, /* pointer to destination pointer */
unsigned long *destlen, /* amount of output space */
unsigned char *source, /* pointer to source data pointer */
unsigned long *sourcelen); /* amount of input available */
Then you can call puff() to decompress a deflate stream that is in memory in
its entirety at source, to a sufficiently sized block of memory for the
decompressed data at dest. puff() is the only external symbol in puff.c The
only C library functions that puff.c needs are setjmp() and longjmp(), which
are used to simplify error checking in the code to improve readability. puff.c
does no memory allocation, and uses less than 2K bytes off of the stack.
If destlen is not enough space for the uncompressed data, then inflate will
return an error without writing more than destlen bytes. Note that this means
that in order to decompress the deflate data successfully, you need to know
the size of the uncompressed data ahead of time.
If needed, puff() can determine the size of the uncompressed data with no
output space. This is done by passing dest equal to (unsigned char *)0. Then
the initial value of *destlen is ignored and *destlen is set to the length of
the uncompressed data. So if the size of the uncompressed data is not known,
then two passes of puff() can be used--first to determine the size, and second
to do the actual inflation after allocating the appropriate memory. Not
pretty, but it works. (This is one of the reasons you should be using zlib.)
The deflate format is self-terminating. If the deflate stream does not end
in *sourcelen bytes, puff() will return an error without reading at or past
endsource.
On return, *sourcelen is updated to the amount of input data consumed, and
*destlen is updated to the size of the uncompressed data. See the comments
in puff.c for the possible return codes for puff().

*
* puff.c is a simple inflate written to be an unambiguous way to specify the
* deflate format. It is not written for speed but rather simplicity. As a
* side benefit, this code might actually be useful when small code is more
* important than speed, such as bootstrap applications. For typical deflate
* data, zlib's inflate() is about four times as fast as puff(). zlib's
* inflate compiles to around 20K on my machine, whereas puff.c compiles to
* around 4K on my machine (a PowerPC using GNU cc). If the faster decode()
* function here is used, then puff() is only twice as slow as zlib's
* inflate().
*
* All dynamically allocated memory comes from the stack. The stack required
* is less than 2K bytes. This code is compatible with 16-bit int's and
* assumes that long's are at least 32 bits. puff.c uses the short data type,
* assumed to be 16 bits, for arrays in order to conserve memory. The code
* works whether integers are stored big endian or little endian.
*
* In the comments below are "Format notes" that describe the inflate process
* and document some of the less obvious aspects of the format. This source
* code is meant to supplement RFC 1951, which formally describes the deflate
* format:

* Decode literal/length and distance codes until an end-of-block code.
*
* Format notes:
*
* - Compressed data that is after the block type if fixed or after the code
* description if dynamic is a combination of literals and length/distance
* pairs terminated by and end-of-block code. Literals are simply Huffman
* coded bytes. A length/distance pair is a coded length followed by a
* coded distance to represent a string that occurs earlier in the
* uncompressed data that occurs again at the current location.
*
* - Literals, lengths, and the end-of-block code are combined into a single
* code of up to 286 symbols. They are 256 literals (0..255), 29 length
* symbols (257..285), and the end-of-block symbol (256).
*
* - There are 256 possible lengths (3..258), and so 29 symbols are not enough
* to represent all of those. Lengths 3..10 and 258 are in fact represented
* by just a length symbol. Lengths 11..257 are represented as a symbol and
* some number of extra bits that are added as an integer to the base length
* of the length symbol. The number of extra bits is determined by the base
* length symbol. These are in the static arrays below, lens[] for the base
* lengths and lext[] for the corresponding number of extra bits.
*
* - The reason that 258 gets its own symbol is that the longest length is used
* often in highly redundant files. Note that 258 can also be coded as the
* base value 227 plus the maximum extra value of 31. While a good deflate
* should never do this, it is not an error, and should be decoded properly.
*
* - If a length is decoded, including its extra bits if any, then it is
* followed a distance code. There are up to 30 distance symbols. Again
* there are many more possible distances (1..32768), so extra bits are added
* to a base value represented by the symbol. The distances 1..4 get their
* own symbol, but the rest require extra bits. The base distances and
* corresponding number of extra bits are below in the static arrays dist[]
* and dext[].
*
* - Literal bytes are simply written to the output. A length/distance pair is
* an instruction to copy previously uncompressed bytes to the output. The
* copy is from distance bytes back in the output stream, copying for length
* bytes.
*
* - Distances pointing before the beginning of the output data are not
* permitted.
*
* - Overlapped copies, where the length is greater than the distance, are
* allowed and common. For example, a distance of one and a length of 258
* simply copies the last byte 258 times. A distance of four and a length of
* twelve copies the last four bytes three times. A simple forward copy
* ignoring whether the length is greater than the distance or not implements
* this correctly. You should not use memcpy() since its behavior is not
* defined for overlapped arrays. You should not use memmove() or bcopy()
* since though their behavior -is- defined for overlapping arrays, it is
* defined to do the wrong thing in this case.

*
* Format notes:
*
* - A dynamic block starts with a description of the literal/length and
* distance codes for that block. New dynamic blocks allow the compressor to
* rapidly adapt to changing data with new codes optimized for that data.
*
* - The codes used by the deflate format are "canonical", which means that
* the actual bits of the codes are generated in an unambiguous way simply
* from the number of bits in each code. Therefore the code descriptions
* are simply a list of code lengths for each symbol.
*
* - The code lengths are stored in order for the symbols, so lengths are
* provided for each of the literal/length symbols, and for each of the
* distance symbols.
*
* - If a symbol is not used in the block, this is represented by a zero as the
* code length. This does not mean a zero-length code, but rather that no
* code should be created for this symbol. There is no way in the deflate
* format to represent a zero-length code.
*
* - The maximum number of bits in a code is 15, so the possible lengths for
* any code are 1..15.
*
* - The fact that a length of zero is not permitted for a code has an
* interesting consequence. Normally if only one symbol is used for a given
* code, then in fact that code could be represented with zero bits. However
* in deflate, that code has to be at least one bit. So for example, if
* only a single distance base symbol appears in a block, then it will be
* represented by a single code of length one, in particular one 0 bit. This
* is an incomplete code, since if a 1 bit is received, it has no meaning,
* and should result in an error. So incomplete distance codes of one symbol
* should be permitted, and the receipt of invalid codes should be handled.
*
* - It is also possible to have a single literal/length code, but that code
* must be the end-of-block code, since every dynamic block has one. This
* is not the most efficient way to create an empty block (an empty fixed
* block is fewer bits), but it is allowed by the format. So incomplete
* literal/length codes of one symbol should also be permitted.
*
* - If there are only literal codes and no lengths, then there are no distance
* codes. This is represented by one distance code with zero bits.
*
* - The list of up to 286 length/literal lengths and up to 30 distance lengths
* are themselves compressed using Huffman codes and run-length encoding. In
* the list of code lengths, a 0 symbol means no code, a 1..15 symbol means
* that length, and the symbols 16, 17, and 18 are run-length instructions.
* Each of 16, 17, and 18 are followed by extra bits to define the length of
* the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10
* zero lengths, and 18 represents 11 to 138 zero lengths. Unused symbols
* are common, hence the special coding for zero lengths.
*
* - The symbols for 0..18 are Huffman coded, and so that code must be
* described first. This is simply a sequence of up to 19 three-bit values
* representing no code (0) or the code length for that symbol (1..7).
*
* - A dynamic block starts with three fixed-size counts from which is computed
* the number of literal/length code lengths, the number of distance code
* lengths, and the number of code length code lengths (ok, you come up with
* a better name!) in the code descriptions. For the literal/length and
* distance codes, lengths after those provided are considered zero, i.e. no
* code. The code length code lengths are received in a permuted order (see
* the order[] array below) to make a short code length code length list more
* likely. As it turns out, very short and very long codes are less likely
* to be seen in a dynamic code description, hence what may appear initially
* to be a peculiar ordering.
*
* - Given the number of literal/length code lengths (nlen) and distance code
* lengths (ndist), then they are treated as one long list of nlen + ndist
* code lengths. Therefore run-length coding can and often does cross the
* boundary between the two sets of lengths.
*
* - So to summarize, the code description at the start of a dynamic block is
* three counts for the number of code lengths for the literal/length codes,
* the distance codes, and the code length codes. This is followed by the
* code length code lengths, three bits each. This is used to construct the
* code length code which is used to read the remainder of the lengths. Then
* the literal/length code lengths and distance lengths are read as a single
* set of lengths using the code length codes. Codes are constructed from
* the resulting two sets of lengths, and then finally you can start
* decoding actual compressed data in the block.
*
* - For reference, a "typical" size for the code description in a dynamic
* block is around 80 bytes.

/* Example of how to use puff().
Usage: puff [-w] [-f] [-nnn] file
... | puff [-w] [-f] [-nnn]
where file is the input file with deflate data, nnn is the number of bytes
of input to skip before inflating (e.g. to skip a zlib or gzip header), and
-w is used to write the decompressed data to stdout. -f is for coverage
testing, and causes pufftest to fail with not enough output space (-f does
a write like -w, so -w is not required). */

Building instructions for the DLL versions of Zlib 1.3.1
========================================================
This directory contains projects that build zlib and minizip using
Microsoft Visual C++ 9.0/10.0.
You don't need to build these projects yourself. You can download the
binaries from:
http://www.winimage.com/zLibDll
More information can be found at this site.
Build instructions for Visual Studio 2008 (32 bits or 64 bits)
--------------------------------------------------------------
- Decompress current zlib, including all contrib/* files
- Open contrib\vstudio\vc9\zlibvc.sln with Microsoft Visual C++ 2008
- Or run: vcbuild /rebuild contrib\vstudio\vc9\zlibvc.sln "Release|Win32"
Build instructions for Visual Studio 2010 (32 bits or 64 bits)
--------------------------------------------------------------
- Decompress current zlib, including all contrib/* files
- Open contrib\vstudio\vc10\zlibvc.sln with Microsoft Visual C++ 2010
Build instructions for Visual Studio 2012 (32 bits or 64 bits)
--------------------------------------------------------------
- Decompress current zlib, including all contrib/* files
- Open contrib\vstudio\vc11\zlibvc.sln with Microsoft Visual C++ 2012
Build instructions for Visual Studio 2013 (32 bits or 64 bits)
--------------------------------------------------------------
- Decompress current zlib, including all contrib/* files
- Open contrib\vstudio\vc12\zlibvc.sln with Microsoft Visual C++ 2013
Build instructions for Visual Studio 2015 (32 bits or 64 bits)
--------------------------------------------------------------
- Decompress current zlib, including all contrib/* files
- Open contrib\vstudio\vc14\zlibvc.sln with Microsoft Visual C++ 2015
Build instructions for Visual Studio 2022 (64 bits)
--------------------------------------------------------------
- Decompress current zlib, including all contrib/* files
- Open contrib\vstudio\vc143\zlibvc.sln with Microsoft Visual C++ 2022
Important
---------
- To use zlibwapi.dll in your application, you must define the
macro ZLIB_WINAPI when compiling your application's source files.
Additional notes
----------------
- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
by Gilles Vollant from the zlib 1.1.x sources, and distributed at
http://www.winimage.com/zLibDll
It uses the WINAPI calling convention for the exported functions, and
includes the minizip functionality. If your application needs that
particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
- The new DLL was renamed because there exist several incompatible
versions of zlib.dll on the Internet.
- There is also an official DLL build of zlib, named zlib1.dll. This one
is exporting the functions using the CDECL convention. See the file
win32\DLL_FAQ.txt found in this zlib distribution.
- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
has a slightly different effect. To avoid compatibility problems, do
not define it here.

Note on the use of DYNAMIC_CRC_TABLE: there is no mutex or semaphore
protection on the static variables used to control the first-use generation

first call get_crc_table() to initialize the tables before allowing more than
one thread to use crc32().
MAKECRCH can be #defined to write out crc32.h. A main() routine is also
produced, so that this one source file can be compiled to an executable.

A CRC of a message is computed on N braids of words in the message, where
each word consists of W bytes (4 or 8). If N is 3, for example, then three
running sparse CRCs are calculated respectively on each braid, at these
indices in the array of words: 0, 3, 6, ..., 1, 4, 7, ..., and 2, 5, 8, ...
This is done starting at a word boundary, and continues until as many blocks
of N * W bytes as are available have been processed. The results are combined
into a single CRC at the end. For this code, N must be in the range 1..6 and
W must be 4 or 8. The upper limit on N can be increased if desired by adding
more #if blocks, extending the patterns apparent in the code. In addition,
crc32.h would need to be regenerated, if the maximum N value is increased.
N and W are chosen empirically by benchmarking the execution time on a given
processor. The choices for N and W below were based on testing on Intel Kaby
Lake i7, AMD Ryzen 7, ARM Cortex-A57, Sparc64-VII, PowerPC POWER9, and MIPS64
Octeon II processors. The Intel, AMD, and ARM processors were all fastest
with N=5, W=8. The Sparc, PowerPC, and MIPS64 were all fastest at N=5, W=4.
They were all tested with either gcc or clang, all using the -O3 optimization
level. Your mileage may vary.

Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

Polynomials over GF(2) are represented in binary, one bit per coefficient,
with the lowest powers in the most significant bit. Then adding polynomials
is just exclusive-or, and multiplying a polynomial by x is a right shift by
one. If we call the above polynomial p, and represent a byte as the
polynomial q, also with the lowest power in the most significant bit (so the
byte 0xb1 is the polynomial x^7+x^3+x^2+1), then the CRC is (q*x^32) mod p,
where a mod b means the remainder after dividing a by b.
This calculation is done using the shift-register method of multiplying and
taking the remainder. The register is initialized to zero, and for each
incoming bit, x^32 is added mod p to the register if the bit is a one (where
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x
(which is shifting right by one and adding x^32 mod p if the bit shifted out
is a one). We start with the highest power (least significant bit) of q and
repeat for all eight bits of q.
The table is simply the CRC of all possible eight bit values. This is all the
information needed to generate CRCs on data a byte at a time for all
combinations of CRC register values and incoming bytes.

/*
* ALGORITHM
*
* The "deflation" process depends on being able to identify portions
* of the input text which are identical to earlier input (within a
* sliding window trailing behind the input currently being processed).
*
* The most straightforward technique turns out to be the fastest for
* most input files: try all possible matches and select the longest.
* The key feature of this algorithm is that insertions into the string
* dictionary are very simple and thus fast, and deletions are avoided
* completely. Insertions are performed at each input character, whereas
* string matches are performed only when the previous match ends. So it
* is preferable to spend more time in matches to allow very fast string
* insertions and avoid deletions. The matching algorithm for small
* strings is inspired from that of Rabin & Karp. A brute force approach
* is used to find longer strings when a small match has been found.
* A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
* (by Leonid Broukhis).
* A previous version of this file used a more sophisticated algorithm
* (by Fiala and Greene) which is guaranteed to run in linear amortized
* time, but has a larger average cost, uses more memory and is patented.
* However the F&G algorithm may be faster for some highly redundant
* files if the parameter max_chain_length (described below) is too large.
*
* ACKNOWLEDGEMENTS
*
* The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
* I found it in 'freeze' written by Leonid Broukhis.
* Thanks to many people for bug reports and testing.

/* We overlay pending_buf and sym_buf. This works since the average size

* bits or less.
*
* Analysis: The longest fixed codes are a length code of 8 bits plus 5
* extra bits, for lengths 131 to 257. The longest fixed distance codes are
* 5 bits plus 13 extra bits, for distances 16385 to 32768. The longest
* possible fixed-codes length/distance pair is then 31 bits total.
*
* sym_buf starts one-fourth of the way into pending_buf. So there are
* three bytes in sym_buf for every four bytes in pending_buf. Each symbol
* in sym_buf is three bytes -- two for the distance and one for the
* literal/length. As each symbol is consumed, the pointer to the next
* sym_buf value to read moves forward three bytes. From that symbol, up to
* 31 bits are written to pending_buf. The closest the written pending_buf
* bits gets to the next sym_buf symbol to read is just before the last
* code is written. At that time, 31*(n - 2) bits have been written, just
* after 24*(n - 2) bits have been consumed from sym_buf. sym_buf starts at
* 8*n bits into pending_buf. (Note that the symbol buffer fills when n - 1
* symbols are written.) The closest the writing gets to what is unread is
* then n + 14 bits. Here n is lit_bufsize, which is 16384 by default, and
* can range from 128 to 32768.
*
* Therefore, at a minimum, there are 142 bits of space between what is
* written and what is read in the overlain buffers, so the symbols cannot
* be overwritten by the compressed data. That space is actually 139 bits,
* due to the three-bit fixed-code block header.
*
* That covers the case where either Z_FIXED is specified, forcing fixed
* codes, or when the use of fixed codes is chosen, because that choice
* results in a smaller compressed block than dynamic codes. That latter
* condition then assures that the above analysis also covers all dynamic
* blocks. A dynamic-code block will only be chosen to be emitted if it has
* fewer bits than a fixed-code block would for the same set of symbols.
* Therefore its average symbol length is assured to be less than 31. So
* the compressed data for a dynamic block also cannot overwrite the
* symbols from which it is being constructed.

/*
Examine all possible prefix codes for a given number of symbols and a
maximum code length in bits to determine the maximum table size for zlib's
inflate. Only complete prefix codes are counted.
Two codes are considered distinct if the vectors of the number of codes per
length are not identical. So permutations of the symbol assignments result
in the same code for the counting, as do permutations of the assignments of
the bit values to the codes (i.e. only canonical codes are counted).
We build a code from shorter to longer lengths, determining how many symbols
are coded at each length. At each step, we have how many symbols remain to
be coded, what the last code length used was, and how many bit patterns of
that length remain unused. Then we add one to the code length and double the
number of unused patterns to graduate to the next code length. We then
assign all portions of the remaining symbols to that code length that
preserve the properties of a correct and eventually complete code. Those
properties are: we cannot use more bit patterns than are available; and when
all the symbols are used, there are exactly zero possible bit patterns left
unused.
The inflate Huffman decoding algorithm uses two-level lookup tables for
speed. There is a single first-level table to decode codes up to root bits
in length (root == 9 for literal/length codes and root == 6 for distance
codes, in the current inflate implementation). The base table has 1 << root
entries and is indexed by the next root bits of input. Codes shorter than
root bits have replicated table entries, so that the correct entry is
pointed to regardless of the bits that follow the short code. If the code is
longer than root bits, then the table entry points to a second-level table.
The size of that table is determined by the longest code with that root-bit
prefix. If that longest code has length len, then the table has size 1 <<
(len - root), to index the remaining bits in that set of codes. Each
subsequent root-bit prefix then has its own sub-table. The total number of
table entries required by the code is calculated incrementally as the number
of codes at each bit length is populated. When all of the codes are shorter
than root bits, then root is reduced to the longest code length, resulting
in a single, smaller, one-level table.
The inflate algorithm also provides for small values of root (relative to
the log2 of the number of symbols), where the shortest code has more bits
than root. In that case, root is increased to the length of the shortest
code. This program, by design, does not handle that case, so it is verified
that the number of symbols is less than 1 << (root + 1).
In order to speed up the examination (by about ten orders of magnitude for
the default arguments), the intermediate states in the build-up of a code
are remembered and previously visited branches are pruned. The memory
required for this will increase rapidly with the total number of symbols and
the maximum code length in bits. However this is a very small price to pay
for the vast speedup.
First, all of the possible prefix codes are counted, and reachable
intermediate states are noted by a non-zero count in a saved-results array.
Second, the intermediate states that lead to (root + 1) bit or longer codes
are used to look at all sub-codes from those junctures for their inflate
memory usage. (The amount of memory used is not affected by the number of
codes of root bits or less in length.) Third, the visited states in the
construction of those sub-codes and the associated calculation of the table
size is recalled in order to avoid recalculating from the same juncture.
Beginning the code examination at (root + 1) bit codes, which is enabled by
identifying the reachable nodes, accounts for about six of the orders of
magnitude of improvement for the default arguments. About another four
orders of magnitude come from not revisiting previous states. Out of
approximately 2x10^16 possible prefix codes, only about 2x10^6 sub-codes
need to be examined to cover all of the possible table memory usage cases
for the default arguments of 286 symbols limited to 15-bit codes.
Note that the uintmax_t type is used for counting. It is quite easy to
exceed the capacity of an eight-byte integer with a large number of symbols
and a large maximum code length, so multiple-precision arithmetic would need
to replace the integer arithmetic in that case. This program will abort if
an overflow occurs. The big_t type identifies where the counting takes
place.
The uintmax_t type is also used for calculating the number of possible codes
remaining at the maximum length. This limits the maximum code length to the
number of bits in a long long minus the number of bits needed to represent
the symbols in a flat code. The code_t type identifies where the bit-pattern
counting takes place.

/* The array for saving results, num[], is indexed with this triplet:
syms: number of symbols remaining to code
left: number of available bit patterns at length len
len: number of bits in the codes currently being assigned
Those indices are constrained thusly when saving results:
syms: 3..totsym (totsym == total symbols to code)
left: 2..syms - 1, but only the evens (so syms == 8 -> 2, 4, 6)
len: 1..max - 1 (max == maximum code length in bits)
syms == 2 is not saved since that immediately leads to a single code. left
must be even, since it represents the number of available bit patterns at
the current length, which is double the number at the previous length. left
ends at syms-1 since left == syms immediately results in a single code.
(left > sym is not allowed since that would result in an incomplete code.)
len is less than max, since the code completes immediately when len == max.
The offset into the array is calculated for the three indices with the first
one (syms) being outermost, and the last one (len) being innermost. We build
the array with length max-1 lists for the len index, with syms-3 of those
for each symbol. There are totsym-2 of those, with each one varying in
length as a function of sym. See the calculation of index in map() for the
index, and the calculation of size in main() for the size of the array.
For the deflate example of 286 symbols limited to 15-bit codes, the array
has 284,284 entries, taking up 2.17 MB for an 8-byte big_t. More than half
of the space allocated for saved results is actually used -- not all
possible triplets are reached in the generation of valid prefix codes.
*/
/* The array for tracking visited states, done[], is itself indexed identically
to the num[] array as described above for the (syms, left, len) triplet.
Each element in the array is further indexed by the (mem, rem) doublet,
where mem is the amount of inflate table space used so far, and rem is the
remaining unused entries in the current inflate sub-table. Each indexed
element is simply one bit indicating whether the state has been visited or
not. Since the ranges for mem and rem are not known a priori, each bit
vector is of a variable size, and grows as needed to accommodate the visited
states. mem and rem are used to calculate a single index in a triangular
array. Since the range of mem is expected in the default case to be about
ten times larger than the range of rem, the array is skewed to reduce the
memory usage, with eight times the range for mem than for rem. See the
calculations for offset and bit in been_here() for the details.
For the deflate example of 286 symbols limited to 15-bit codes, the bit
vectors grow to total 5.5 MB, in addition to the 4.3 MB done array itself.

/* Approach to just fitting a requested compressed size:
fitblk performs three compression passes on a portion of the input
data in order to determine how much of that input will compress to
nearly the requested output block size. The first pass generates
enough deflate blocks to produce output to fill the requested
output size plus a specified excess amount (see the EXCESS define
below). The last deflate block may go quite a bit past that, but
is discarded. The second pass decompresses and recompresses just
the compressed data that fit in the requested plus excess sized
buffer. The deflate process is terminated after that amount of
input, which is less than the amount consumed on the first pass.
The last deflate block of the result will be of a comparable size
to the final product, so that the header for that deflate block and
the compression ratio for that block will be about the same as in
the final product. The third compression pass decompresses the
result of the second step, but only the compressed data up to the
requested size minus an amount to allow the compressed stream to
complete (see the MARGIN define below). That will result in a
final compressed stream whose length is less than or equal to the
requested size. Assuming sufficient input and a requested size
greater than a few hundred bytes, the shortfall will typically be
less than ten bytes.
If the input is short enough that the first compression completes
before filling the requested output size, then that compressed
stream is return with no recompression.
EXCESS is chosen to be just greater than the shortfall seen in a
two pass approach similar to the above. That shortfall is due to
the last deflate block compressing more efficiently with a smaller
header on the second pass. EXCESS is set to be large enough so
that there is enough uncompressed data for the second pass to fill
out the requested size, and small enough so that the final deflate
block of the second pass will be close in size to the final deflate
block of the third and final pass. MARGIN is chosen to be just
large enough to assure that the final compression has enough room
to complete in all cases.

/*
gun [ -t ] [ name ... ]
decompresses the data in the named gzip files. If no arguments are given,
gun will decompress from stdin to stdout. The names must end in .gz, -gz,
.z, -z, _z, or .Z. The uncompressed data will be written to a file name
with the suffix stripped. On success, the original file is deleted. On
failure, the output file is deleted. For most failures, the command will
continue to process the remaining names on the command line. A memory
allocation failure will abort the command. If -t is specified, then the
listed files or stdin will be tested as gzip files for integrity (without
checking for a proper suffix), no output will be written, and no files
will be deleted.
Like gzip, gun allows concatenated gzip streams and will decompress them,
writing all of the uncompressed data to the output. Unlike gzip, gun allows
an empty file on input, and will produce no error writing an empty output
file.
gun will also decompress files made by Unix compress, which uses LZW
compression. These files are automatically detected by virtue of their
magic header bytes. Since the end of Unix compress stream is marked by the
end-of-file, they cannot be concatenated. If a Unix compress stream is
encountered in an input file, it is the last stream in that file.
Like gunzip and uncompress, the file attributes of the original compressed
file are maintained in the final uncompressed file, to the extent that the
user permissions allow it.
On my Mac OS X PowerPC G4, gun is almost twice as fast as gunzip (version
1.2.4) is on the same file, when gun is linked with zlib 1.2.2. Also the
LZW decompression provided by gun is about twice as fast as the standard
Unix uncompress command.

/*
gzappend takes a gzip file and appends to it, compressing files from the
command line or data from stdin. The gzip file is written to directly, to
avoid copying that file, in case it's large. Note that this results in the
unfriendly behavior that if gzappend fails, the gzip file is corrupted.
This program was written to illustrate the use of the new Z_BLOCK option of
zlib 1.2.x's inflate() function. This option returns from inflate() at each
block boundary to facilitate locating and modifying the last block bit at
the start of the final deflate block. Also whether using Z_BLOCK or not,
another required feature of zlib 1.2.x is that inflate() now provides the
number of unused bits in the last input byte used. gzappend will not work
with versions of zlib earlier than 1.2.1.
gzappend first decompresses the gzip file internally, discarding all but
the last 32K of uncompressed data, and noting the location of the last block
bit and the number of unused bits in the last byte of the compressed data.
The gzip trailer containing the CRC-32 and length of the uncompressed data
is verified. This trailer will be later overwritten.
Then the last block bit is cleared by seeking back in the file and rewriting
the byte that contains it. Seeking forward, the last byte of the compressed
data is saved along with the number of unused bits to initialize deflate.
A deflate process is initialized, using the last 32K of the uncompressed
data from the gzip file to initialize the dictionary. If the total
uncompressed data was less than 32K, then all of it is used to initialize
the dictionary. The deflate output bit buffer is also initialized with the
last bits from the original deflate stream. From here on, the data to
append is simply compressed using deflate, and written to the gzip file.
When that is complete, the new CRC-32 and uncompressed length are written
as the trailer of the gzip file.

/*
gzjoin takes one or more gzip files on the command line and writes out a
single gzip file that will uncompress to the concatenation of the
uncompressed data from the individual gzip files. gzjoin does this without
having to recompress any of the data and without having to calculate a new
crc32 for the concatenated uncompressed data. gzjoin does however have to
decompress all of the input data in order to find the bits in the compressed
data that need to be modified to concatenate the streams.
gzjoin does not do an integrity check on the input gzip files other than
checking the gzip header and decompressing the compressed data. They are
otherwise assumed to be complete and correct.
Each joint between gzip files removes at least 18 bytes of previous trailer
and subsequent header, and inserts an average of about three bytes to the
compressed data in order to connect the streams. The output gzip file
has a minimal ten-byte gzip header with no file name or modification time.
This program was written to illustrate the use of the Z_BLOCK option of
inflate() and the crc32_combine() function. gzjoin will not compile with
versions of zlib earlier than 1.2.3.

/*
gzlog provides a mechanism for frequently appending short strings to a gzip
file that is efficient both in execution time and compression ratio. The
strategy is to write the short strings in an uncompressed form to the end of
the gzip file, only compressing when the amount of uncompressed data has
reached a given threshold.
gzlog also provides protection against interruptions in the process due to
system crashes. The status of the operation is recorded in an extra field
in the gzip file, and is only updated once the gzip file is brought to a
valid state. The last data to be appended or compressed is saved in an
auxiliary file, so that if the operation is interrupted, it can be completed
the next time an append operation is attempted.
gzlog maintains another auxiliary file with the last 32K of data from the
compressed portion, which is preloaded for the compression of the subsequent
data. This minimizes the impact to the compression ratio of appending.
*/
/*
Operations Concept:
Files (log name "foo"):
foo.gz -- gzip file with the complete log
foo.add -- last message to append or last data to compress
foo.dict -- dictionary of the last 32K of data for next compression
foo.temp -- temporary dictionary file for compression after this one
foo.lock -- lock file for reading and writing the other files
foo.repairs -- log file for log file recovery operations (not compressed)
gzip file structure:
- fixed-length (no file name) header with extra field (see below)
- compressed data ending initially with empty stored block
- uncompressed data filling out originally empty stored block and
subsequent stored blocks as needed (16K max each)
- gzip trailer
- no junk at end (no other gzip streams)
When appending data, the information in the first three items above plus the
foo.add file are sufficient to recover an interrupted append operation. The
extra field has the necessary information to restore the start of the last
stored block and determine where to append the data in the foo.add file, as
well as the crc and length of the gzip data before the append operation.
The foo.add file is created before the gzip file is marked for append, and
deleted after the gzip file is marked as complete. So if the append
operation is interrupted, the data to add will still be there. If due to
some external force, the foo.add file gets deleted between when the append
operation was interrupted and when recovery is attempted, the gzip file will
still be restored, but without the appended data.
When compressing data, the information in the first two items above plus the
foo.add file are sufficient to recover an interrupted compress operation.
The extra field has the necessary information to find the end of the
compressed data, and contains both the crc and length of just the compressed
data and of the complete set of data including the contents of the foo.add
file.
Again, the foo.add file is maintained during the compress operation in case
of an interruption. If in the unlikely event the foo.add file with the data
to be compressed is missing due to some external force, a gzip file with
just the previous compressed data will be reconstructed. In this case, all
of the data that was to be compressed is lost (approximately one megabyte).
This will not occur if all that happened was an interruption of the compress
operation.
The third state that is marked is the replacement of the old dictionary with
the new dictionary after a compress operation. Once compression is
complete, the gzip file is marked as being in the replace state. This
completes the gzip file, so an interrupt after being so marked does not
result in recompression. Then the dictionary file is replaced, and the gzip
file is marked as completed. This state prevents the possibility of
restarting compression with the wrong dictionary file.
All three operations are wrapped by a lock/unlock procedure. In order to
gain exclusive access to the log files, first a foo.lock file must be
exclusively created. When all operations are complete, the lock is
released by deleting the foo.lock file. If when attempting to create the
lock file, it already exists and the modify time of the lock file is more
than five minutes old (set by the PATIENCE define below), then the old
lock file is considered stale and deleted, and the exclusive creation of
the lock file is retried. To assure that there are no false assessments
of the staleness of the lock file, the operations periodically touch the
lock file to update the modified date.
Following is the definition of the extra field with all of the information
required to enable the above append and compress operations and their
recovery if interrupted. Multi-byte values are stored little endian
(consistent with the gzip format). File pointers are eight bytes long.
The crc's and lengths for the gzip trailer are four bytes long. (Note that
the length at the end of a gzip file is used for error checking only, and
for large files is actually the length modulo 2^32.) The stored block
length is two bytes long. The gzip extra field two-byte identification is
"ap" for append. It is assumed that writing the extra field to the file is
an "atomic" operation. That is, either all of the extra field is written
to the file, or none of it is, if the operation is interrupted right at the
point of updating the extra field. This is a reasonable assumption, since
the extra field is within the first 52 bytes of the file, which is smaller
than any expected block size for a mass storage device (usually 512 bytes or
larger).
Extra field (35 bytes):
- Pointer to first stored block length -- this points to the two-byte length
of the first stored block, which is followed by the two-byte, one's
complement of that length. The stored block length is preceded by the
three-bit header of the stored block, which is the actual start of the
stored block in the deflate format. See the bit offset field below.
- Pointer to the last stored block length. This is the same as above, but
for the last stored block of the uncompressed data in the gzip file.
Initially this is the same as the first stored block length pointer.
When the stored block gets to 16K (see the MAX_STORE define), then a new
stored block as added, at which point the last stored block length pointer
is different from the first stored block length pointer. When they are
different, the first bit of the last stored block header is eight bits, or
one byte back from the block length.
- Compressed data crc and length. This is the crc and length of the data
that is in the compressed portion of the deflate stream. These are used
only in the event that the foo.add file containing the data to compress is
lost after a compress operation is interrupted.
- Total data crc and length. This is the crc and length of all of the data
stored in the gzip file, compressed and uncompressed. It is used to
reconstruct the gzip trailer when compressing, as well as when recovering
interrupted operations.
- Final stored block length. This is used to quickly find where to append,
and allows the restoration of the original final stored block state when
an append operation is interrupted.
- First stored block start as the number of bits back from the final stored
block first length byte. This value is in the range of 3..10, and is
stored as the low three bits of the final byte of the extra field after
subtracting three (0..7). This allows the last-block bit of the stored
block header to be updated when a new stored block is added, for the case
when the first stored block and the last stored block are the same. (When
they are different, the numbers of bits back is known to be eight.) This
also allows for new compressed data to be appended to the old compressed
data in the compress operation, overwriting the previous first stored
block, or for the compressed data to be terminated and a valid gzip file
reconstructed on the off chance that a compression operation was
interrupted and the data to compress in the foo.add file was deleted.
- The operation in process. This is the next two bits in the last byte (the
bits under the mask 0x18). The are interpreted as 0: nothing in process,
1: append in process, 2: compress in process, 3: replace in process.
- The top three bits of the last byte in the extra field are reserved and
are currently set to zero.
Main procedure:
- Exclusively create the foo.lock file using the O_CREAT and O_EXCL modes of
the system open() call. If the modify time of an existing lock file is
more than PATIENCE seconds old, then the lock file is deleted and the
exclusive create is retried.
- Load the extra field from the foo.gz file, and see if an operation was in
progress but not completed. If so, apply the recovery procedure below.
- Perform the append procedure with the provided data.
- If the uncompressed data in the foo.gz file is 1MB or more, apply the
compress procedure.
- Delete the foo.lock file.
Append procedure:
- Put what to append in the foo.add file so that the operation can be
restarted if this procedure is interrupted.
- Mark the foo.gz extra field with the append operation in progress.
+ Restore the original last-block bit and stored block length of the last
stored block from the information in the extra field, in case a previous
append operation was interrupted.
- Append the provided data to the last stored block, creating new stored
blocks as needed and updating the stored blocks last-block bits and
lengths.
- Update the crc and length with the new data, and write the gzip trailer.
- Write over the extra field (with a single write operation) with the new
pointers, lengths, and crc's, and mark the gzip file as not in process.
Though there is still a foo.add file, it will be ignored since nothing
is in process. If a foo.add file is leftover from a previously
completed operation, it is truncated when writing new data to it.
- Delete the foo.add file.
Compress and replace procedures:
- Read all of the uncompressed data in the stored blocks in foo.gz and write
it to foo.add. Also write foo.temp with the last 32K of that data to
provide a dictionary for the next invocation of this procedure.
- Rewrite the extra field marking foo.gz with a compression in process.
* If there is no data provided to compress (due to a missing foo.add file
when recovering), reconstruct and truncate the foo.gz file to contain
only the previous compressed data and proceed to the step after the next
one. Otherwise ...
- Compress the data with the dictionary in foo.dict, and write to the
foo.gz file starting at the bit immediately following the last previously
compressed block. If there is no foo.dict, proceed anyway with the
compression at slightly reduced efficiency. (For the foo.dict file to be
missing requires some external failure beyond simply the interruption of
a compress operation.) During this process, the foo.lock file is
periodically touched to assure that that file is not considered stale by
another process before we're done. The deflation is terminated with a
non-last empty static block (10 bits long), that is then located and
written over by a last-bit-set empty stored block.
- Append the crc and length of the data in the gzip file (previously
calculated during the append operations).
- Write over the extra field with the updated stored block offsets, bits
back, crc's, and lengths, and mark foo.gz as in process for a replacement
of the dictionary.
@ Delete the foo.add file.
- Replace foo.dict with foo.temp.
- Write over the extra field, marking foo.gz as complete.
Recovery procedure:
- If not a replace recovery, read in the foo.add file, and provide that data
to the appropriate recovery below. If there is no foo.add file, provide
a zero data length to the recovery. In that case, the append recovery
restores the foo.gz to the previous compressed + uncompressed data state.
For the compress recovery, a missing foo.add file results in foo.gz being
restored to the previous compressed-only data state.
- Append recovery:
- Pick up append at + step above
- Compress recovery:
- Pick up compress at * step above
- Replace recovery:
- Pick up compress at @ step above
- Log the repair with a date stamp in foo.repairs

/*
The gzlog object allows writing short messages to a gzipped log file,
opening the log file locked for small bursts, and then closing it. The log
object works by appending stored (uncompressed) data to the gzip file until
1 MB has been accumulated. At that time, the stored data is compressed, and
replaces the uncompressed data in the file. The log file is truncated to
its new size at that time. After each write operation, the log file is a
valid gzip file that can decompressed to recover what was written.
The gzlog operations can be interrupted at any point due to an application or
system crash, and the log file will be recovered the next time the log is
opened with gzlog_open().

<h2 align="center"> zlib Usage Example </h2>
We often get questions about how the <tt>deflate()</tt> and <tt>inflate()</tt> functions should be used.
Users wonder when they should provide more input, when they should use more output,
what to do with a <tt>Z_BUF_ERROR</tt>, how to make sure the process terminates properly, and
so on. So for those who have read <tt>zlib.h</tt> (a few times), and
would like further edification, below is an annotated example in C of simple routines to compress and decompress
from an input file to an output file using <tt>deflate()</tt> and <tt>inflate()</tt> respectively. The
annotations are interspersed between lines of the code. So please read between the lines.
We hope this helps explain some of the intricacies of <em>zlib</em>.
<p>
Without further ado, here is the program <a href="zpipe.c"><tt>zpipe.c</tt></a>:

We now include the header files for the required definitions. From
<tt>stdio.h</tt> we use <tt>fopen()</tt>, <tt>fread()</tt>, <tt>fwrite()</tt>,
<tt>feof()</tt>, <tt>ferror()</tt>, and <tt>fclose()</tt> for file i/o, and
<tt>fputs()</tt> for error messages. From <tt>string.h</tt> we use
<tt>strcmp()</tt> for command line argument processing.
From <tt>assert.h</tt> we use the <tt>assert()</tt> macro.
From <tt>zlib.h</tt>
we use the basic compression functions <tt>deflateInit()</tt>,
<tt>deflate()</tt>, and <tt>deflateEnd()</tt>, and the basic decompression
functions <tt>inflateInit()</tt>, <tt>inflate()</tt>, and
<tt>inflateEnd()</tt>.

This is an ugly hack required to avoid corruption of the input and output data on
Windows/MS-DOS systems. Without this, those systems would assume that the input and output
files are text, and try to convert the end-of-line characters from one standard to
another. That would corrupt binary data, and in particular would render the compressed data unusable.
This sets the input and output to binary which suppresses the end-of-line conversions.
<tt>SET_BINARY_MODE()</tt> will be used later on <tt>stdin</tt> and <tt>stdout</tt>, at the beginning of <tt>main()</tt>.

<tt>CHUNK</tt> is simply the buffer size for feeding data to and pulling data
from the <em>zlib</em> routines. Larger buffer sizes would be more efficient,
especially for <tt>inflate()</tt>. If the memory is available, buffers sizes
on the order of 128K or 256K bytes should be used.

The <tt>def()</tt> routine compresses data from an input file to an output file. The output data
will be in the <em>zlib</em> format, which is different from the <em>gzip</em> or <em>zip</em>
formats. The <em>zlib</em> format has a very small header of only two bytes to identify it as
a <em>zlib</em> stream and to provide decoding information, and a four-byte trailer with a fast
check value to verify the integrity of the uncompressed data after decoding.
<pre><b>
/* Compress from file source to file dest until EOF on source.
def() returns Z_OK on success, Z_MEM_ERROR if memory could not be
allocated for processing, Z_STREAM_ERROR if an invalid compression
level is supplied, Z_VERSION_ERROR if the version of zlib.h and the
version of the library linked do not match, or Z_ERRNO if there is
an error reading or writing the files. */

Here are the local variables for <tt>def()</tt>. <tt>ret</tt> will be used for <em>zlib</em>
return codes. <tt>flush</tt> will keep track of the current flushing state for <tt>deflate()</tt>,
which is either no flushing, or flush to completion after the end of the input file is reached.
<tt>have</tt> is the amount of data returned from <tt>deflate()</tt>. The <tt>strm</tt> structure
is used to pass information to and from the <em>zlib</em> routines, and to maintain the
<tt>deflate()</tt> state. <tt>in</tt> and <tt>out</tt> are the input and output buffers for
<tt>deflate()</tt>.

The first thing we do is to initialize the <em>zlib</em> state for compression using
<tt>deflateInit()</tt>. This must be done before the first use of <tt>deflate()</tt>.
The <tt>zalloc</tt>, <tt>zfree</tt>, and <tt>opaque</tt> fields in the <tt>strm</tt>
structure must be initialized before calling <tt>deflateInit()</tt>. Here they are
set to the <em>zlib</em> constant <tt>Z_NULL</tt> to request that <em>zlib</em> use
the default memory allocation routines. An application may also choose to provide
custom memory allocation routines here. <tt>deflateInit()</tt> will allocate on the
order of 256K bytes for the internal state.
(See <a href="zlib_tech.html"><em>zlib Technical Details</em></a>.)
<p>
<tt>deflateInit()</tt> is called with a pointer to the structure to be initialized and
the compression level, which is an integer in the range of -1 to 9. Lower compression
levels result in faster execution, but less compression. Higher levels result in
greater compression, but slower execution. The <em>zlib</em> constant Z_DEFAULT_COMPRESSION,
equal to -1,
provides a good compromise between compression and speed and is equivalent to level 6.
Level 0 actually does no compression at all, and in fact expands the data slightly to produce
the <em>zlib</em> format (it is not a byte-for-byte copy of the input).
More advanced applications of <em>zlib</em>
may use <tt>deflateInit2()</tt> here instead. Such an application may want to reduce how
much memory will be used, at some price in compression. Or it may need to request a
<em>gzip</em> header and trailer instead of a <em>zlib</em> header and trailer, or raw
encoding with no header or trailer at all.
<p>
We must check the return value of <tt>deflateInit()</tt> against the <em>zlib</em> constant
<tt>Z_OK</tt> to make sure that it was able to
allocate memory for the internal state, and that the provided arguments were valid.
<tt>deflateInit()</tt> will also check that the version of <em>zlib</em> that the <tt>zlib.h</tt>
file came from matches the version of <em>zlib</em> actually linked with the program. This
is especially important for environments in which <em>zlib</em> is a shared library.
<p>
Note that an application can initialize multiple, independent <em>zlib</em> streams, which can
operate in parallel. The state information maintained in the structure allows the <em>zlib</em>
routines to be reentrant.
<pre><b>
/* allocate deflate state */
strm.zalloc = Z_NULL;
strm.zfree = Z_NULL;
strm.opaque = Z_NULL;
ret = deflateInit(&strm, level);
if (ret != Z_OK)
return ret;
</b></pre><!-- -->
With the pleasantries out of the way, now we can get down to business. The outer <tt>do</tt>-loop
reads all of the input file and exits at the bottom of the loop once end-of-file is reached.
This loop contains the only call of <tt>deflate()</tt>. So we must make sure that all of the
input data has been processed and that all of the output data has been generated and consumed
before we fall out of the loop at the bottom.
<pre><b>
/* compress until end of file */
do {
</b></pre>
We start off by reading data from the input file. The number of bytes read is put directly
into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also
check to see if end-of-file on the input has been reached using feof().
If we are at the end of file, then <tt>flush</tt> is set to the
<em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to
indicate that this is the last chunk of input data to compress.
If we are not yet at the end of the input, then the <em>zlib</em>
constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still
in the middle of the uncompressed data.
<p>
If there is an error in reading from the input file, the process is aborted with
<tt>deflateEnd()</tt> being called to free the allocated <em>zlib</em> state before returning
the error. We wouldn't want a memory leak, now would we? <tt>deflateEnd()</tt> can be called
at any time after the state has been initialized. Once that's done, <tt>deflateInit()</tt> (or
<tt>deflateInit2()</tt>) would have to be called to start a new compression process. There is
no point here in checking the <tt>deflateEnd()</tt> return code. The deallocation can't fail.
<pre><b>
strm.avail_in = fread(in, 1, CHUNK, source);
if (ferror(source)) {
(void)deflateEnd(&strm);
return Z_ERRNO;
}
flush = feof(source) ? Z_FINISH : Z_NO_FLUSH;
strm.next_in = in;
</b></pre><!-- -->
The inner <tt>do</tt>-loop passes our chunk of input data to <tt>deflate()</tt>, and then
keeps calling <tt>deflate()</tt> until it is done producing output. Once there is no more
new output, <tt>deflate()</tt> is guaranteed to have consumed all of the input, i.e.,
<tt>avail_in</tt> will be zero.
<pre><b>
/* run deflate() on input until output buffer not full, finish
compression if all of source has been read in */
do {
</b></pre>
Output space is provided to <tt>deflate()</tt> by setting <tt>avail_out</tt> to the number
of available output bytes and <tt>next_out</tt> to a pointer to that space.
<pre><b>
strm.avail_out = CHUNK;
strm.next_out = out;
</b></pre>
Now we call the compression engine itself, <tt>deflate()</tt>. It takes as many of the
<tt>avail_in</tt> bytes at <tt>next_in</tt> as it can process, and writes as many as
<tt>avail_out</tt> bytes to <tt>next_out</tt>. Those counters and pointers are then
updated past the input data consumed and the output data written. It is the amount of
output space available that may limit how much input is consumed.
Hence the inner loop to make sure that
all of the input is consumed by providing more output space each time. Since <tt>avail_in</tt>
and <tt>next_in</tt> are updated by <tt>deflate()</tt>, we don't have to mess with those
between <tt>deflate()</tt> calls until it's all used up.
<p>
The parameters to <tt>deflate()</tt> are a pointer to the <tt>strm</tt> structure containing
the input and output information and the internal compression engine state, and a parameter
indicating whether and how to flush data to the output. Normally <tt>deflate</tt> will consume
several K bytes of input data before producing any output (except for the header), in order
to accumulate statistics on the data for optimum compression. It will then put out a burst of
compressed data, and proceed to consume more input before the next burst. Eventually,
<tt>deflate()</tt>
must be told to terminate the stream, complete the compression with provided input data, and
write out the trailer check value. <tt>deflate()</tt> will continue to compress normally as long
as the flush parameter is <tt>Z_NO_FLUSH</tt>. Once the <tt>Z_FINISH</tt> parameter is provided,
<tt>deflate()</tt> will begin to complete the compressed output stream. However depending on how
much output space is provided, <tt>deflate()</tt> may have to be called several times until it
has provided the complete compressed stream, even after it has consumed all of the input. The flush
parameter must continue to be <tt>Z_FINISH</tt> for those subsequent calls.
<p>
There are other values of the flush parameter that are used in more advanced applications. You can
force <tt>deflate()</tt> to produce a burst of output that encodes all of the input data provided
so far, even if it wouldn't have otherwise, for example to control data latency on a link with
compressed data. You can also ask that <tt>deflate()</tt> do that as well as erase any history up to
that point so that what follows can be decompressed independently, for example for random access
applications. Both requests will degrade compression by an amount depending on how often such
requests are made.
<p>
<tt>deflate()</tt> has a return value that can indicate errors, yet we do not check it here. Why
not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through
<tt>deflate()</tt>'s return values and dispense with them one by one. The possible values are
<tt>Z_OK</tt>, <tt>Z_STREAM_END</tt>, <tt>Z_STREAM_ERROR</tt>, or <tt>Z_BUF_ERROR</tt>. <tt>Z_OK</tt>
is, well, ok. <tt>Z_STREAM_END</tt> is also ok and will be returned for the last call of
<tt>deflate()</tt>. This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt>
until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not
initialized properly, but we did initialize it properly. There is no harm in checking for
<tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some
other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state.
<tt>Z_BUF_ERROR</tt> will be explained further below, but
suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume
more input or produce more output. <tt>deflate()</tt> can be called again with more output space
or more available input, which it will be in this code.
<pre><b>
ret = deflate(&strm, flush); /* no bad return value */
assert(ret != Z_STREAM_ERROR); /* state not clobbered */
</b></pre>
Now we compute how much output <tt>deflate()</tt> provided on the last call, which is the
difference between how much space was provided before the call, and how much output space
is still available after the call. Then that data, if any, is written to the output file.
We can then reuse the output buffer for the next call of <tt>deflate()</tt>. Again if there
is a file i/o error, we call <tt>deflateEnd()</tt> before returning to avoid a memory leak.
<pre><b>
have = CHUNK - strm.avail_out;
if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
(void)deflateEnd(&strm);
return Z_ERRNO;
}
</b></pre>
The inner <tt>do</tt>-loop is repeated until the last <tt>deflate()</tt> call fails to fill the
provided output buffer. Then we know that <tt>deflate()</tt> has done as much as it can with
the provided input, and that all of that input has been consumed. We can then fall out of this
loop and reuse the input buffer.
<p>
The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill
the output buffer, leaving <tt>avail_out</tt> greater than zero. However suppose that
<tt>deflate()</tt> has no more output, but just so happened to exactly fill the output buffer!
<tt>avail_out</tt> is zero, and we can't tell that <tt>deflate()</tt> has done all it can.
As far as we know, <tt>deflate()</tt>
has more output for us. So we call it again. But now <tt>deflate()</tt> produces no output
at all, and <tt>avail_out</tt> remains unchanged as <tt>CHUNK</tt>. That <tt>deflate()</tt> call
wasn't able to do anything, either consume input or produce output, and so it returns
<tt>Z_BUF_ERROR</tt>. (See, I told you I'd cover this later.) However this is not a problem at
all. Now we finally have the desired indication that <tt>deflate()</tt> is really done,
and so we drop out of the inner loop to provide more input to <tt>deflate()</tt>.
<p>
With <tt>flush</tt> set to <tt>Z_FINISH</tt>, this final set of <tt>deflate()</tt> calls will
complete the output stream. Once that is done, subsequent calls of <tt>deflate()</tt> would return
<tt>Z_STREAM_ERROR</tt> if the flush parameter is not <tt>Z_FINISH</tt>, and do no more processing
until the state is reinitialized.
<p>
Some applications of <em>zlib</em> have two loops that call <tt>deflate()</tt>
instead of the single inner loop we have here. The first loop would call
without flushing and feed all of the data to <tt>deflate()</tt>. The second loop would call
<tt>deflate()</tt> with no more
data and the <tt>Z_FINISH</tt> parameter to complete the process. As you can see from this
example, that can be avoided by simply keeping track of the current flush state.
<pre><b>
} while (strm.avail_out == 0);
assert(strm.avail_in == 0); /* all input will be used */
</b></pre><!-- -->
Now we check to see if we have already processed all of the input file. That information was
saved in the <tt>flush</tt> variable, so we see if that was set to <tt>Z_FINISH</tt>. If so,
then we're done and we fall out of the outer loop. We're guaranteed to get <tt>Z_STREAM_END</tt>
from the last <tt>deflate()</tt> call, since we ran it until the last chunk of input was
consumed and all of the output was generated.
<pre><b>
/* done when last data in file processed */
} while (flush != Z_FINISH);
assert(ret == Z_STREAM_END); /* stream will be complete */
</b></pre><!-- -->
The process is complete, but we still need to deallocate the state to avoid a memory leak
(or rather more like a memory hemorrhage if you didn't do this). Then
finally we can return with a happy return value.
<pre><b>
/* clean up and return */
(void)deflateEnd(&strm);
return Z_OK;
}
</b></pre><!-- -->
Now we do the same thing for decompression in the <tt>inf()</tt> routine. <tt>inf()</tt>
decompresses what is hopefully a valid <em>zlib</em> stream from the input file and writes the
uncompressed data to the output file. Much of the discussion above for <tt>def()</tt>
applies to <tt>inf()</tt> as well, so the discussion here will focus on the differences between
the two.
<pre><b>
/* Decompress from file source to file dest until stream ends or EOF.
inf() returns Z_OK on success, Z_MEM_ERROR if memory could not be
allocated for processing, Z_DATA_ERROR if the deflate data is
invalid or incomplete, Z_VERSION_ERROR if the version of zlib.h and
the version of the library linked do not match, or Z_ERRNO if there
is an error reading or writing the files. */
int inf(FILE *source, FILE *dest)
{
</b></pre>
The local variables have the same functionality as they do for <tt>def()</tt>. The
only difference is that there is no <tt>flush</tt> variable, since <tt>inflate()</tt>
can tell from the <em>zlib</em> stream itself when the stream is complete.
<pre><b>
int ret;
unsigned have;
z_stream strm;
unsigned char in[CHUNK];
unsigned char out[CHUNK];
</b></pre><!-- -->
The initialization of the state is the same, except that there is no compression level,
of course, and two more elements of the structure are initialized. <tt>avail_in</tt>
and <tt>next_in</tt> must be initialized before calling <tt>inflateInit()</tt>. This
is because the application has the option to provide the start of the zlib stream in
order for <tt>inflateInit()</tt> to have access to information about the compression
method to aid in memory allocation. In the current implementation of <em>zlib</em>
(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of
<tt>inflate()</tt> anyway. However those fields must be initialized since later versions
of <em>zlib</em> that provide more compression methods may take advantage of this interface.
In any case, no decompression is performed by <tt>inflateInit()</tt>, so the
<tt>avail_out</tt> and <tt>next_out</tt> fields do not need to be initialized before calling.
<p>
Here <tt>avail_in</tt> is set to zero and <tt>next_in</tt> is set to <tt>Z_NULL</tt> to
indicate that no input data is being provided.
<pre><b>
/* allocate inflate state */
strm.zalloc = Z_NULL;
strm.zfree = Z_NULL;
strm.opaque = Z_NULL;
strm.avail_in = 0;
strm.next_in = Z_NULL;
ret = inflateInit(&strm);
if (ret != Z_OK)
return ret;
</b></pre><!-- -->
The outer <tt>do</tt>-loop decompresses input until <tt>inflate()</tt> indicates
that it has reached the end of the compressed data and has produced all of the uncompressed
output. This is in contrast to <tt>def()</tt> which processes all of the input file.
If end-of-file is reached before the compressed data self-terminates, then the compressed
data is incomplete and an error is returned.
<pre><b>
/* decompress until deflate stream ends or end of file */
do {
</b></pre>
We read input data and set the <tt>strm</tt> structure accordingly. If we've reached the
end of the input file, then we leave the outer loop and report an error, since the
compressed data is incomplete. Note that we may read more data than is eventually consumed
by <tt>inflate()</tt>, if the input file continues past the <em>zlib</em> stream.
For applications where <em>zlib</em> streams are embedded in other data, this routine would
need to be modified to return the unused data, or at least indicate how much of the input
data was not used, so the application would know where to pick up after the <em>zlib</em> stream.
<pre><b>
strm.avail_in = fread(in, 1, CHUNK, source);
if (ferror(source)) {
(void)inflateEnd(&strm);
return Z_ERRNO;
}
if (strm.avail_in == 0)
break;
strm.next_in = in;
</b></pre><!-- -->
The inner <tt>do</tt>-loop has the same function it did in <tt>def()</tt>, which is to
keep calling <tt>inflate()</tt> until has generated all of the output it can with the
provided input.
<pre><b>
/* run inflate() on input until output buffer not full */
do {
</b></pre>
Just like in <tt>def()</tt>, the same output space is provided for each call of <tt>inflate()</tt>.
<pre><b>
strm.avail_out = CHUNK;
strm.next_out = out;
</b></pre>
Now we run the decompression engine itself. There is no need to adjust the flush parameter, since
the <em>zlib</em> format is self-terminating. The main difference here is that there are
return values that we need to pay attention to. <tt>Z_DATA_ERROR</tt>
indicates that <tt>inflate()</tt> detected an error in the <em>zlib</em> compressed data format,
which means that either the data is not a <em>zlib</em> stream to begin with, or that the data was
corrupted somewhere along the way since it was compressed. The other error to be processed is
<tt>Z_MEM_ERROR</tt>, which can occur since memory allocation is deferred until <tt>inflate()</tt>
needs it, unlike <tt>deflate()</tt>, whose memory is allocated at the start by <tt>deflateInit()</tt>.
<p>
Advanced applications may use
<tt>deflateSetDictionary()</tt> to prime <tt>deflate()</tt> with a set of likely data to improve the
first 32K or so of compression. This is noted in the <em>zlib</em> header, so <tt>inflate()</tt>
requests that that dictionary be provided before it can start to decompress. Without the dictionary,
correct decompression is not possible. For this routine, we have no idea what the dictionary is,
so the <tt>Z_NEED_DICT</tt> indication is converted to a <tt>Z_DATA_ERROR</tt>.
<p>
<tt>inflate()</tt> can also return <tt>Z_STREAM_ERROR</tt>, which should not be possible here,
but could be checked for as noted above for <tt>def()</tt>. <tt>Z_BUF_ERROR</tt> does not need to be
checked for here, for the same reasons noted for <tt>def()</tt>. <tt>Z_STREAM_END</tt> will be
checked for later.
<pre><b>
ret = inflate(&strm, Z_NO_FLUSH);
assert(ret != Z_STREAM_ERROR); /* state not clobbered */
switch (ret) {
case Z_NEED_DICT:
ret = Z_DATA_ERROR; /* and fall through */
case Z_DATA_ERROR:
case Z_MEM_ERROR:
(void)inflateEnd(&strm);
return ret;
}
</b></pre>
The output of <tt>inflate()</tt> is handled identically to that of <tt>deflate()</tt>.
<pre><b>
have = CHUNK - strm.avail_out;
if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
(void)inflateEnd(&strm);
return Z_ERRNO;
}
</b></pre>
The inner <tt>do</tt>-loop ends when <tt>inflate()</tt> has no more output as indicated
by not filling the output buffer, just as for <tt>deflate()</tt>. In this case, we cannot
assert that <tt>strm.avail_in</tt> will be zero, since the deflate stream may end before the file
does.
<pre><b>
} while (strm.avail_out == 0);
</b></pre><!-- -->
The outer <tt>do</tt>-loop ends when <tt>inflate()</tt> reports that it has reached the
end of the input <em>zlib</em> stream, has completed the decompression and integrity
check, and has provided all of the output. This is indicated by the <tt>inflate()</tt>
return value <tt>Z_STREAM_END</tt>. The inner loop is guaranteed to leave <tt>ret</tt>
equal to <tt>Z_STREAM_END</tt> if the last chunk of the input file read contained the end
of the <em>zlib</em> stream. So if the return value is not <tt>Z_STREAM_END</tt>, the
loop continues to read more input.
<pre><b>
/* done when inflate() says it's done */
} while (ret != Z_STREAM_END);
</b></pre><!-- -->
At this point, decompression successfully completed, or we broke out of the loop due to no
more data being available from the input file. If the last <tt>inflate()</tt> return value
is not <tt>Z_STREAM_END</tt>, then the <em>zlib</em> stream was incomplete and a data error
is returned. Otherwise, we return with a happy return value. Of course, <tt>inflateEnd()</tt>
is called first to avoid a memory leak.
<pre><b>
/* clean up and return */
(void)inflateEnd(&strm);
return ret == Z_STREAM_END ? Z_OK : Z_DATA_ERROR;
}
</b></pre><!-- -->
That ends the routines that directly use <em>zlib</em>. The following routines make this
a command-line program by running data through the above routines from <tt>stdin</tt> to
<tt>stdout</tt>, and handling any errors reported by <tt>def()</tt> or <tt>inf()</tt>.
<p>
<tt>zerr()</tt> is used to interpret the possible error codes from <tt>def()</tt>
and <tt>inf()</tt>, as detailed in their comments above, and print out an error message.
Note that these are only a subset of the possible return values from <tt>deflate()</tt>
and <tt>inflate()</tt>.
<pre><b>
/* report a zlib or i/o error */
void zerr(int ret)
{
fputs("zpipe: ", stderr);
switch (ret) {
case Z_ERRNO:
if (ferror(stdin))
fputs("error reading stdin\n", stderr);
if (ferror(stdout))
fputs("error writing stdout\n", stderr);
break;
case Z_STREAM_ERROR:
fputs("invalid compression level\n", stderr);
break;

break;
case Z_MEM_ERROR:
fputs("out of memory\n", stderr);
break;
case Z_VERSION_ERROR:
fputs("zlib version mismatch!\n", stderr);
}
}
</b></pre><!-- -->
Here is the <tt>main()</tt> routine used to test <tt>def()</tt> and <tt>inf()</tt>. The
<tt>zpipe</tt> command is simply a compression pipe from <tt>stdin</tt> to <tt>stdout</tt>, if
no arguments are given, or it is a decompression pipe if <tt>zpipe -d</tt> is used. If any other
arguments are provided, no compression or decompression is performed. Instead a usage
message is displayed. Examples are <tt>zpipe < foo.txt > foo.txt.z</tt> to compress, and
<tt>zpipe -d < foo.txt.z > foo.txt</tt> to decompress.

// Illustrate the use of Z_BLOCK, inflatePrime(), and inflateSetDictionary()
// for random access of a compressed file. A file containing a raw deflate
// stream is provided on the command line. The compressed stream is decoded in
// its entirety, and an index built with access points about every SPAN bytes
// in the uncompressed output. The compressed file is left open, and can then
// be read randomly, having to decompress on the average SPAN/2 uncompressed
// bytes before getting to the desired block of data.
//
// An access point can be created at the start of any deflate block, by saving
// the starting file offset and bit of that block, and the 32K bytes of
// uncompressed data that precede that block. Also the uncompressed offset of
// that block is saved to provide a reference for locating a desired starting
// point in the uncompressed stream. deflate_index_build() decompresses the
// input raw deflate stream a block at a time, and at the end of each block
// decides if enough uncompressed data has gone by to justify the creation of a
// new access point. If so, that point is saved in a data structure that grows
// as needed to accommodate the points.
//
// To use the index, an offset in the uncompressed data is provided, for which
// the latest access point at or preceding that offset is located in the index.
// The input file is positioned to the specified location in the index, and if
// necessary the first few bits of the compressed data is read from the file.
// inflate is initialized with those bits and the 32K of uncompressed data, and
// decompression then proceeds until the desired offset in the file is reached.
// Then decompression continues to read the requested uncompressed data from
// the file.
//
// There is some fair bit of overhead to starting inflation for the random
// access, mainly copying the 32K byte dictionary. If small pieces of the file
// are being accessed, it would make sense to implement a cache to hold some
// lookahead to avoid many calls to deflate_index_extract() for small lengths.
//
// Another way to build an index would be to use inflateCopy(). That would not
// be constrained to have access points at block boundaries, but would require
// more memory per access point, and could not be saved to a file due to the
// use of pointers in the state. The approach here allows for storage of the
// index in a file.

strm provides the memory allocation functions and window buffer on input,
and provides information on the unused input on return. For Z_DATA_ERROR
returns, strm will also provide an error message.
in() and out() are the call-back input and output functions. When
inflateBack() needs more input, it calls in(). When inflateBack() has
filled the window with output, or when it completes with data in the
window, it calls out() to write out the data. The application must not
change the provided input until in() is called again or inflateBack()
returns. The application must not change the window/output buffer until
inflateBack() returns.
in() and out() are called with a descriptor parameter provided in the
inflateBack() call. This parameter can be a structure that provides the
information required to do the read or write, as well as accumulated
information on the input and output such as totals and check values.
in() should return zero on failure. out() should return non-zero on
failure. If either in() or out() fails, than inflateBack() returns a
Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
was in() or out() that caused in the error. Otherwise, inflateBack()
returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
error, or Z_MEM_ERROR if it could not allocate memory for the state.
inflateBack() can also return Z_STREAM_ERROR if the input parameters
are not correct, i.e. strm is Z_NULL or the state was not initialized.

/*
Decode literal, length, and distance codes and write out the resulting
literal and match bytes until either not enough input or output is
available, an end-of-block is encountered, or a data error is encountered.
When large enough input and output buffers are supplied to inflate(), for
example, a 16K input buffer and a 64K output buffer, more than 95% of the
inflate execution time is spent in this routine.
Entry assumptions:
state->mode == LEN
strm->avail_in >= 6
strm->avail_out >= 258
start >= strm->avail_out
state->bits < 8
On return, state->mode is one of:
LEN -- ran out of enough output space or enough available input
TYPE -- reached end of block code, inflate() to interpret next block
BAD -- error in block data
Notes:
- The maximum input bits used by a length/distance pair is 15 bits for the
length code, 5 bits for the length extra, 15 bits for the distance code,
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
Therefore if strm->avail_in >= 6, then there is enough input to avoid
checking for available input while decoding.
- The maximum bytes that a single length/distance pair can output is 258
bytes, which is the maximum length that can be coded. inflate_fast()
requires strm->avail_out >= 258 for each loop to avoid checking for
output space.

- Deferring match copy and interspersed it with decoding subsequent codes
- Swapping literal/length else

- Larger unrolled copy loops (three is about right)
- Moving len -= 3 statement into middle of loop

*/
/*
* Change history:
*
* 1.2.beta0 24 Nov 2002
* - First version -- complete rewrite of inflate to simplify code, avoid
* creation of window when not needed, minimize use of window when it is
* needed, make inffast.c even faster, implement gzip decoding, and to
* improve code readability and style over the previous zlib inflate code
*
* 1.2.beta1 25 Nov 2002
* - Use pointers for available input and output checking in inffast.c
* - Remove input and output counters in inffast.c
* - Change inffast.c entry and loop from avail_in >= 7 to >= 6
* - Remove unnecessary second byte pull from length extra in inffast.c
* - Unroll direct copy to three copies per loop in inffast.c
*
* 1.2.beta2 4 Dec 2002
* - Change external routine names to reduce potential conflicts
* - Correct filename to inffixed.h for fixed tables in inflate.c
* - Make hbuf[] unsigned char to match parameter type in inflate.c
* - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
* to avoid negation problem on Alphas (64 bit) in inflate.c
*
* 1.2.beta3 22 Dec 2002
* - Add comments on state->bits assertion in inffast.c
* - Add comments on op field in inftrees.h
* - Fix bug in reuse of allocated window after inflateReset()
* - Remove bit fields--back to byte structure for speed
* - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
* - Change post-increments to pre-increments in inflate_fast(), PPC biased?
* - Add compile time option, POSTINC, to use post-increments instead (Intel?)
* - Make MATCH copy in inflate() much faster for when inflate_fast() not used
* - Use local copies of stream next and avail values, as well as local bit
* buffer and bit count in inflate()--for speed when inflate_fast() not used
*
* 1.2.beta4 1 Jan 2003
* - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
* - Move a comment on output buffer sizes from inffast.c to inflate.c
* - Add comments in inffast.c to introduce the inflate_fast() routine
* - Rearrange window copies in inflate_fast() for speed and simplification
* - Unroll last copy for window match in inflate_fast()
* - Use local copies of window variables in inflate_fast() for speed
* - Pull out common wnext == 0 case for speed in inflate_fast()
* - Make op and len in inflate_fast() unsigned for consistency
* - Add FAR to lcode and dcode declarations in inflate_fast()
* - Simplified bad distance check in inflate_fast()
* - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
* source file infback.c to provide a call-back interface to inflate for
* programs like gzip and unzip -- uses window as output buffer to avoid
* window copying
*
* 1.2.beta5 1 Jan 2003
* - Improved inflateBack() interface to allow the caller to provide initial
* input in strm.
* - Fixed stored blocks bug in inflateBack()
*
* 1.2.beta6 4 Jan 2003
* - Added comments in inffast.c on effectiveness of POSTINC
* - Typecasting all around to reduce compiler warnings
* - Changed loops from while (1) or do {} while (1) to for (;;), again to
* make compilers happy
* - Changed type of window in inflateBackInit() to unsigned char *
*
* 1.2.beta7 27 Jan 2003
* - Changed many types to unsigned or unsigned short to avoid warnings
* - Added inflateCopy() function
*
* 1.2.0 9 Mar 2003
* - Changed inflateBack() interface to provide separate opaque descriptors
* for the in() and out() functions
* - Changed inflateBack() argument and in_func typedef to swap the length
* and buffer address return values for the input function
* - Check next_in and next_out for Z_NULL on entry to inflate()
*
* The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

It is also called to create a window for dictionary data when a dictionary

Providing output buffers larger than 32K to inflate() should provide a speed
advantage, since only the last 32K of output is copied to the sliding window

The advantage may be dependent on the size of the processor's data caches.

inflate() uses a state machine to process as much input data and generate as
much output data as possible before returning. The state machine is
structured roughly as follows:
for (;;) switch (state) {
...
case STATEn:
if (not enough input data or output space to make progress)
return;
... make progress ...
state = STATEm;
break;
...
}
so when inflate() is called again, the same case is attempted again, and
if the appropriate resources are provided, the machine proceeds to the
next state. The NEEDBITS() macro is usually the way the state evaluates
whether it can proceed or should return. NEEDBITS() does the return if
the requested bits are not available. The typical use of the BITS macros
is:
NEEDBITS(n);
... do something with BITS(n) ...
DROPBITS(n);
where NEEDBITS(n) either returns from inflate() if there isn't enough
input left to load n bits into the accumulator, or it continues. BITS(n)
gives the low n bits in the accumulator. When done, DROPBITS(n) drops
the low n bits off the accumulator. INITBITS() clears the accumulator
and sets the number of available bits to zero. BYTEBITS() discards just
enough bits to put the accumulator on a byte boundary. After BYTEBITS()
and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
if there is no input available. The decoding of variable length codes uses
PULLBYTE() directly in order to pull just enough bytes to decode the next
code, and no more.
Some states loop until they get enough input, making sure that enough
state information is maintained to continue the loop where it left off
if NEEDBITS() returns in the loop. For example, want, need, and keep
would all have to actually be part of the saved state in case NEEDBITS()
returns:
case STATEw:
while (want < need) {
NEEDBITS(n);
keep[want++] = BITS(n);
DROPBITS(n);
}
state = STATEx;
case STATEx:
As shown above, if the next state is also the next case, then the break
is omitted.
A state may also return if there is not enough output space available to
complete that state. Those states are copying stored data, writing a
literal byte, and copying a matching string.
When returning, a "goto inf_leave" is used to update the total counters,
update the check value, and determine whether any progress has been made
during that inflate() call in order to return the proper return code.
Progress is defined as a change in either strm->avail_in or strm->avail_out.
When there is a window, goto inf_leave will update the window with the last
output written. If a goto inf_leave occurs in the middle of decompression
and there is no window currently, goto inf_leave will create one and copy
output to the window for the next call of inflate().
In this implementation, the flush parameter of inflate() only affects the
return code (per zlib.h). inflate() always writes as much as possible to
strm->next_out, given the space available and the provided input--the effect
documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers
the allocation of and copying into a sliding window until necessary, which
provides the effect documented in zlib.h for Z_FINISH when the entire input
stream available. So the only thing the flush parameter actually does is:
when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it
will return Z_BUF_ERROR if it has not reached the end of the stream.

Process a set of code lengths to create a canonical Huffman code. The
code lengths are lens[0..codes-1]. Each length corresponds to the
symbols 0..codes-1. The Huffman code is generated by first sorting the
symbols by length from short to long, and retaining the symbol order
for codes with equal lengths. Then the code starts with all zero bits
for the first code of the shortest length, and the codes are integer
increments for the same length, and zeros are appended as the length
increases. For the deflate format, these bits are stored backwards
from their more natural integer increment ordering, and so when the
decoding tables are built in the large loop below, the integer codes
are incremented backwards.
This routine assumes, but does not check, that all of the entries in
lens[] are in the range 0..MAXBITS. The caller must assure this.
1..MAXBITS is interpreted as that code length. zero means that that
symbol does not occur in this code.
The codes are sorted by computing a count of codes for each length,
creating from that a table of starting indices for each length in the
sorted table, and then entering the symbols in order in the sorted
table. The sorted table is work[], with that space being provided by
the caller.
The length counts are used for other purposes as well, i.e. finding
the minimum and maximum length codes, determining if there are any
codes at all, checking for a valid set of lengths, and looking ahead
at length counts to determine sub-table sizes when building the
decoding tables.

Create and fill in decoding tables. In this loop, the table being
filled is at next and has curr index bits. The code being used is huff
with length len. That code is converted to an index by dropping drop
bits off of the bottom. For codes where len is less than drop + curr,
those top drop + curr - len bits are incremented through all values to
fill the table with replicated entries.
root is the number of index bits for the root table. When len exceeds
root, sub-tables are created pointed to by the root entry with an index
of the low root bits of huff. This is saved in low to check for when a
new sub-table should be started. drop is zero when the root table is
being filled, and drop is root when sub-tables are being filled.
When a new sub-table is needed, it is necessary to look ahead in the
code lengths to determine what size sub-table is needed. The length
counts are used for this, and so count[] is decremented as codes are
entered in the tables.
used keeps track of how many table entries have been allocated from the
provided *table space. It is checked for LENS and DIST tables against
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
the initial root table size constants. See the comments in inftrees.h
for more information.
sym increments through all symbols, and the loop terminates when
all codes of length max, i.e. all codes, have been processed. This
routine permits incomplete codes, so another loop after this one fills
in the rest of the decoding tables with invalid code markers.

See below some functions declarations for Visual Basic.
Frequently Asked Question:
Q: Each time I use the compress function I get the -5 error (not enough
room in the output buffer).
A: Make sure that the length of the compressed buffer is passed by
reference ("as any"), not by value ("as long"). Also check that
before the call of compress this length is equal to the total size of
the compressed buffer and not zero.

Got the answer! (I haven't had time to check this but it's what I got, and
looks correct):
He has the following routines working:
compress

gzopen
gzwrite
gzread
gzclose

Here is another example from Michael <michael_borgsys@hotmail.com> that he
says conforms to the VB guidelines, and that solves the problem of not
knowing the uncompressed size by storing it at the end of the file:
'Calling the functions:
'bracket meaning: <parameter> [optional] {Range of possible values}
'Call subCompressFile(<path with filename to compress> [, <path with
filename to write to>, [level of compression {1..9}]])

ZLIB version 1.3.1 for OS/400 installation instructions
1) Download and unpack the zlib tarball to some IFS directory.
(i.e.: /path/to/the/zlib/ifs/source/directory)
If the installed IFS command supports gzip format, this is straightforward,
else you have to unpack first to some directory on a system supporting it,
then move the whole directory to the IFS via the network (via SMB or FTP).
2) Edit the configuration parameters in the compilation script.
EDTF STMF('/path/to/the/zlib/ifs/source/directory/os400/make.sh')
Tune the parameters according to your needs if not matching the defaults.
Save the file and exit after edition.
3) Enter qshell, then work in the zlib OS/400 specific directory.
QSH
cd /path/to/the/zlib/ifs/source/directory/os400
4) Compile and install
sh make.sh
The script will:
- create the libraries, objects and IFS directories for the zlib environment,
- compile all modules,
- create a service program,
- create a static and a dynamic binding directory,
- install header files for C/C++ and for ILE/RPG, both for compilation in
DB2 and IFS environments.
That's all.
Notes: For OS/400 ILE RPG programmers, a /copy member defining the ZLIB
API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
In the ILE environment, the same definitions are available from
file zlib.inc located in the same IFS include directory as the
C/C++ header files.
Please read comments in this member for more information.
Remember that most foreign textual data are ASCII coded: this
implementation does not handle conversion from/to ASCII, so
text data code conversions must be done explicitly.
Mainly for the reason above, always open zipped files in binary mode.

* ZLIB.INC - Interface to the general purpose compression library
*
* ILE RPG400 version by Patrick Monnerat, DATASPHERE.
* Version 1.3.1
*
*
* WARNING:
* Procedures inflateInit(), inflateInit2(), deflateInit(),
* deflateInit2() and inflateBackInit() need to be called with
* two additional arguments:
* the package version string and the stream control structure.
* size. This is needed because RPG lacks some macro feature.
* Call these procedures as:
* inflateInit(...: ZLIB_VERSION: %size(z_stream))

/*
These memory tracking routines are provided to zlib and track all of zlib's
allocations and deallocations, check for LIFO operations, keep a current
and high water mark of total bytes requested, optionally set a limit on the
total memory that can be allocated, and when done check for memory leaks.
They are used as follows:
z_stream strm;
mem_setup(&strm) initializes the memory tracking and sets the
zalloc, zfree, and opaque members of strm to use
memory tracking for all zlib operations on strm
mem_limit(&strm, limit) sets a limit on the total bytes requested -- a
request that exceeds this limit will result in an
allocation failure (returns NULL) -- setting the
limit to zero means no limit, which is the default
after mem_setup()
mem_used(&strm, "msg") prints to stderr "msg" and the total bytes used
mem_high(&strm, "msg") prints to stderr "msg" and the high water mark
mem_done(&strm, "msg") ends memory tracking, releases all allocations
for the tracking as well as leaked zlib blocks, if
any. If there was anything unusual, such as leaked
blocks, non-FIFO frees, or frees of addresses not
allocated, then "msg" and information about the
problem is printed to stderr. If everything is
normal, nothing is printed. mem_done resets the
strm members to Z_NULL to use the default memory
allocation routines on the next zlib initialization
using strm.

/*
* ALGORITHM
*
* The "deflation" process uses several Huffman trees. The more
* common source values are represented by shorter bit sequences.
*
* Each code tree is stored in a compressed form which is itself
* a Huffman encoding of the lengths of all the code strings (in
* ascending order by source values). The actual code strings are
* reconstructed from the lengths in the inflate process, as described
* in the deflate specification.

Decompresses the source buffer into the destination buffer. *sourceLen is
the byte length of the source buffer. Upon entry, *destLen is the total size
of the destination buffer, which must be large enough to hold the entire
uncompressed data. (The size of the uncompressed data must have been saved
previously by the compressor and transmitted to the decompressor by some
mechanism outside the scope of this compression library.) Upon exit,
*destLen is the size of the decompressed data and *sourceLen is the number
of source bytes consumed. Upon return, source + *sourceLen points to the
first unused input byte.
uncompress returns Z_OK if success, Z_MEM_ERROR if there was not enough
memory, Z_BUF_ERROR if there was not enough room in the output buffer, or
Z_DATA_ERROR if the input data was corrupted, including if the input data is
an incomplete zlib stream.

- ZLIB1.DLL is the common build of zlib as a DLL.
(Please remark the character '1' in the name.)
Applications that link to ZLIB1.DLL can rely on the following
specification:
* The exported symbols are exclusively defined in the source
files "zlib.h" and "zlib.def", found in an official zlib
source distribution.
* The symbols are exported by name, not by ordinal.
* The exported names are undecorated.
* The calling convention of functions is "C" (CDECL).
* The ZLIB1.DLL binary is linked to MSVCRT.DLL.
The archive in which ZLIB1.DLL is bundled contains compiled
test programs that must run with a valid build of ZLIB1.DLL.
It is recommended to download the prebuilt DLL from the zlib
web site, instead of building it yourself, to avoid potential
incompatibilities that could be introduced by your compiler
and build settings. If you do build the DLL yourself, please
make sure that it complies with all the above requirements,
and it runs with the precompiled test programs, bundled with
the original ZLIB1.DLL distribution.
If, for any reason, you need to build an incompatible DLL,
please use a different file name.
2. Why did you change the name of the DLL to ZLIB1.DLL?
What happened to the old ZLIB.DLL?
- The old ZLIB.DLL, built from zlib-1.1.4 or earlier, required
compilation settings that were incompatible to those used by
a static build. The DLL settings were supposed to be enabled
by defining the macro ZLIB_DLL, before including "zlib.h".
Incorrect handling of this macro was silently accepted at
build time, resulting in two major problems:
* ZLIB_DLL was missing from the old makefile. When building
the DLL, not all people added it to the build options. In
consequence, incompatible incarnations of ZLIB.DLL started
to circulate around the net.
* When switching from using the static library to using the
DLL, applications had to define the ZLIB_DLL macro and
to recompile all the sources that contained calls to zlib
functions. Failure to do so resulted in creating binaries
that were unable to run with the official ZLIB.DLL build.
The only possible solution that we could foresee was to make
a binary-incompatible change in the DLL interface, in order to
remove the dependency on the ZLIB_DLL macro, and to release
the new DLL under a different name.
We chose the name ZLIB1.DLL, where '1' indicates the major
zlib version number. We hope that we will not have to break
the binary compatibility again, at least not as long as the
zlib-1.x series will last.
There is still a ZLIB_DLL macro, that can trigger a more
efficient build and use of the DLL, but compatibility no
longer dependents on it.
3. Can I build ZLIB.DLL from the new zlib sources, and replace
an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier?
- In principle, you can do it by assigning calling convention
keywords to the macros ZEXPORT and ZEXPORTVA. In practice,
it depends on what you mean by "an old ZLIB.DLL", because the
old DLL exists in several mutually-incompatible versions.
You have to find out first what kind of calling convention is
being used in your particular ZLIB.DLL build, and to use the
same one in the new build. If you don't know what this is all
about, you might be better off if you would just leave the old
DLL intact.
4. Can I compile my application using the new zlib interface, and
link it to an old ZLIB.DLL, that was built from zlib-1.1.4 or
earlier?
- The official answer is "no"; the real answer depends again on
what kind of ZLIB.DLL you have. Even if you are lucky, this
course of action is unreliable.
If you rebuild your application and you intend to use a newer
version of zlib (post- 1.1.4), it is strongly recommended to
link it to the new ZLIB1.DLL.
5. Why are the zlib symbols exported by name, and not by ordinal?
- Although exporting symbols by ordinal is a little faster, it
is risky. Any single glitch in the maintenance or use of the
DEF file that contains the ordinals can result in incompatible
builds and frustrating crashes. Simply put, the benefits of
exporting symbols by ordinal do not justify the risks.
Technically, it should be possible to maintain ordinals in
the DEF file, and still export the symbols by name. Ordinals
exist in every DLL, and even if the dynamic linking performed
at the DLL startup is searching for names, ordinals serve as
hints, for a faster name lookup. However, if the DEF file
contains ordinals, the Microsoft linker automatically builds
an implib that will cause the executables linked to it to use
those ordinals, and not the names. It is interesting to
notice that the GNU linker for Win32 does not suffer from this
problem.
It is possible to avoid the DEF file if the exported symbols
are accompanied by a "__declspec(dllexport)" attribute in the
source files. You can do this in zlib by predefining the
ZLIB_DLL macro.
6. I see that the ZLIB1.DLL functions use the "C" (CDECL) calling
convention. Why not use the STDCALL convention?
STDCALL is the standard convention in Win32, and I need it in
my Visual Basic project!
(For readability, we use CDECL to refer to the convention
triggered by the "__cdecl" keyword, STDCALL to refer to
the convention triggered by "__stdcall", and FASTCALL to
refer to the convention triggered by "__fastcall".)
- Most of the native Windows API functions (without varargs) use
indeed the WINAPI convention (which translates to STDCALL in
Win32), but the standard C functions use CDECL. If a user
application is intrinsically tied to the Windows API (e.g.
it calls native Windows API functions such as CreateFile()),
sometimes it makes sense to decorate its own functions with
WINAPI. But if ANSI C or POSIX portability is a goal (e.g.
it calls standard C functions such as fopen()), it is not a
sound decision to request the inclusion of <windows.h>, or to
use non-ANSI constructs, for the sole purpose to make the user
functions STDCALL-able.
The functionality offered by zlib is not in the category of
"Windows functionality", but is more like "C functionality".
Technically, STDCALL is not bad; in fact, it is slightly
faster than CDECL, and it works with variable-argument
functions, just like CDECL. It is unfortunate that, in spite
of using STDCALL in the Windows API, it is not the default
convention used by the C compilers that run under Windows.
The roots of the problem reside deep inside the unsafety of
the K&R-style function prototypes, where the argument types
are not specified; but that is another story for another day.
The remaining fact is that CDECL is the default convention.
Even if an explicit convention is hard-coded into the function
prototypes inside C headers, problems may appear. The
necessity to expose the convention in users' callbacks is one
of these problems.
The calling convention issues are also important when using
zlib in other programming languages. Some of them, like Ada
(GNAT) and Fortran (GNU G77), have C bindings implemented
initially on Unix, and relying on the C calling convention.
On the other hand, the pre- .NET versions of Microsoft Visual
Basic require STDCALL, while Borland Delphi prefers, although
it does not require, FASTCALL.
In fairness to all possible uses of zlib outside the C
programming language, we choose the default "C" convention.
Anyone interested in different bindings or conventions is
encouraged to maintain specialized projects. The "contrib/"
directory from the zlib distribution already holds a couple
of foreign bindings, such as Ada, C++, and Delphi.
7. I need a DLL for my Visual Basic project. What can I do?
- Define the ZLIB_WINAPI macro before including "zlib.h", when
building both the DLL and the user application (except that
you don't need to define anything when using the DLL in Visual
Basic). The ZLIB_WINAPI macro will switch on the WINAPI
(STDCALL) convention. The name of this DLL must be different
than the official ZLIB1.DLL.
Gilles Vollant has contributed a build named ZLIBWAPI.DLL,
with the ZLIB_WINAPI macro turned on, and with the minizip
functionality built in. For more information, please read
the notes inside "contrib/vstudio/readme.txt", found in the
zlib distribution.
8. I need to use zlib in my Microsoft .NET project. What can I
do?
- Henrik Ravn has contributed a .NET wrapper around zlib. Look
into contrib/dotzlib/, inside the zlib distribution.
9. If my application uses ZLIB1.DLL, should I link it to
MSVCRT.DLL? Why?
- It is not required, but it is recommended to link your
application to MSVCRT.DLL, if it uses ZLIB1.DLL.
The executables (.EXE, .DLL, etc.) that are involved in the
same process and are using the C run-time library (i.e. they
are calling standard C functions), must link to the same
library. There are several libraries in the Win32 system:
CRTDLL.DLL, MSVCRT.DLL, the static C libraries, etc.
Since ZLIB1.DLL is linked to MSVCRT.DLL, the executables that
depend on it should also be linked to MSVCRT.DLL.
10. Why are you saying that ZLIB1.DLL and my application should
be linked to the same C run-time (CRT) library? I linked my
application and my DLLs to different C libraries (e.g. my
application to a static library, and my DLLs to MSVCRT.DLL),
and everything works fine.
- If a user library invokes only pure Win32 API (accessible via
<windows.h> and the related headers), its DLL build will work
in any context. But if this library invokes standard C API,
things get more complicated.
There is a single Win32 library in a Win32 system. Every
function in this library resides in a single DLL module, that
is safe to call from anywhere. On the other hand, there are
multiple versions of the C library, and each of them has its
own separate internal state. Standalone executables and user
DLLs that call standard C functions must link to a C run-time
(CRT) library, be it static or shared (DLL). Intermixing
occurs when an executable (not necessarily standalone) and a
DLL are linked to different CRTs, and both are running in the
same process.
Intermixing multiple CRTs is possible, as long as their
internal states are kept intact. The Microsoft Knowledge Base
articles KB94248 "HOWTO: Use the C Run-Time" and KB140584
"HOWTO: Link with the Correct C Run-Time (CRT) Library"
mention the potential problems raised by intermixing.
If intermixing works for you, it's because your application
and DLLs are avoiding the corruption of each of the CRTs'
internal states, maybe by careful design, or maybe by fortune.
Also note that linking ZLIB1.DLL to non-Microsoft CRTs, such
as those provided by Borland, raises similar problems.
11. Why are you linking ZLIB1.DLL to MSVCRT.DLL?
- MSVCRT.DLL exists on every Windows 95 with a new service pack
installed, or with Microsoft Internet Explorer 4 or later, and
on all other Windows 4.x or later (Windows 98, Windows NT 4,
or later). It is freely distributable; if not present in the
system, it can be downloaded from Microsoft or from other
software provider for free.
The fact that MSVCRT.DLL does not exist on a virgin Windows 95
is not so problematic. Windows 95 is scarcely found nowadays,
Microsoft ended its support a long time ago, and many recent
applications from various vendors, including Microsoft, do not
even run on it. Furthermore, no serious user should run
Windows 95 without a proper update installed.
12. Why are you not linking ZLIB1.DLL to
<<my favorite C run-time library>> ?
- We considered and abandoned the following alternatives:
* Linking ZLIB1.DLL to a static C library (LIBC.LIB, or
LIBCMT.LIB) is not a good option. People are using the DLL
mainly to save disk space. If you are linking your program
to a static C library, you may as well consider linking zlib
in statically, too.
* Linking ZLIB1.DLL to CRTDLL.DLL looks appealing, because
CRTDLL.DLL is present on every Win32 installation.
Unfortunately, it has a series of problems: it does not
work properly with Microsoft's C++ libraries, it does not
provide support for 64-bit file offsets, (and so on...),
and Microsoft discontinued its support a long time ago.
* Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied
with the Microsoft .NET platform, and Visual C++ 7.0/7.1,
raises problems related to the status of ZLIB1.DLL as a
system component. According to the Microsoft Knowledge Base
article KB326922 "INFO: Redistribution of the Shared C
Runtime Component in Visual C++ .NET", MSVCR70.DLL and
MSVCR71.DLL are not supposed to function as system DLLs,
because they may clash with MSVCRT.DLL. Instead, the
application's installer is supposed to put these DLLs
(if needed) in the application's private directory.
If ZLIB1.DLL depends on a non-system runtime, it cannot
function as a redistributable system component.
* Linking ZLIB1.DLL to non-Microsoft runtimes, such as
Borland's, or Cygwin's, raises problems related to the
reliable presence of these runtimes on Win32 systems.
It's easier to let the DLL build of zlib up to the people
who distribute these runtimes, and who may proceed as
explained in the answer to Question 14.
13. If ZLIB1.DLL cannot be linked to MSVCR70.DLL or MSVCR71.DLL,
how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0
(Visual Studio .NET) or newer?
- Due to the problems explained in the Microsoft Knowledge Base
article KB326922 (see the previous answer), the C runtime that
comes with the VC7 environment is no longer considered a
system component. That is, it should not be assumed that this
runtime exists, or may be installed in a system directory.
Since ZLIB1.DLL is supposed to be a system component, it may
not depend on a non-system component.
In order to link ZLIB1.DLL and your application to MSVCRT.DLL
in VC7, you need the library of Visual C++ 6.0 or older. If
you don't have this library at hand, it's probably best not to
use ZLIB1.DLL.
We are hoping that, in the future, Microsoft will provide a
way to build applications linked to a proper system runtime,
from the Visual C++ environment. Until then, you have a
couple of alternatives, such as linking zlib in statically.
If your application requires dynamic linking, you may proceed
as explained in the answer to Question 14.
14. I need to link my own DLL build to a CRT different than
MSVCRT.DLL. What can I do?
- Feel free to rebuild the DLL from the zlib sources, and link
it the way you want. You should, however, clearly state that
your build is unofficial. You should give it a different file
name, and/or install it in a private directory that can be
accessed by your application only, and is not visible to the
others (i.e. it's neither in the PATH, nor in the SYSTEM or
SYSTEM32 directories). Otherwise, your build may clash with
applications that link to the official build.
For example, in Cygwin, zlib is linked to the Cygwin runtime
CYGWIN1.DLL, and it is distributed under the name CYGZ.DLL.
15. May I include additional pieces of code that I find useful,
link them in ZLIB1.DLL, and export them?
- No. A legitimate build of ZLIB1.DLL must not include code
that does not originate from the official zlib source code.
But you can make your own private DLL build, under a different
file name, as suggested in the previous answer.
For example, zlib is a part of the VCL library, distributed
with Borland Delphi and C++ Builder. The DLL build of VCL
is a redistributable file, named VCLxx.DLL.
16. May I remove some functionality out of ZLIB1.DLL, by enabling
macros like NO_GZCOMPRESS or NO_GZIP at compile time?
- No. A legitimate build of ZLIB1.DLL must provide the complete
zlib functionality, as implemented in the official zlib source
code. But you can make your own private DLL build, under a
different file name, as suggested in the previous answer.

ZLIB DATA COMPRESSION LIBRARY
zlib 1.3.1 is a general purpose data compression library. All the code is
thread safe. The data format used by the zlib library is described by RFCs
(Request for Comments) 1950 to 1952 in the files
http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
and rfc1952.txt (gzip format).
All functions of the compression library are documented in the file zlib.h
(volunteer to write man pages welcome, contact zlib@gzip.org). Two compiled
examples are distributed in this package, example and minigzip. The example_d
and minigzip_d flavors validate that the zlib1.dll file is working correctly.
Questions about zlib should be sent to <zlib@gzip.org>. The zlib home page
is http://zlib.net/ . Before reporting a problem, please check this site to
verify that you have the latest version of zlib; otherwise get the latest
version and check whether the problem still exists or not.
PLEASE read DLL_FAQ.txt, and the zlib FAQ http://zlib.net/zlib_faq.html before
asking for help.
Manifest:
The package zlib-1.3.1-win32-x86.zip will contain the following files:
README-WIN32.txt This document
ChangeLog Changes since previous zlib packages
DLL_FAQ.txt Frequently asked questions about zlib1.dll
zlib.3.pdf Documentation of this library in Adobe Acrobat format
example.exe A statically-bound example (using zlib.lib, not the dll)
example.pdb Symbolic information for debugging example.exe
example_d.exe A zlib1.dll bound example (using zdll.lib)
example_d.pdb Symbolic information for debugging example_d.exe
minigzip.exe A statically-bound test program (using zlib.lib, not the dll)
minigzip.pdb Symbolic information for debugging minigzip.exe
minigzip_d.exe A zlib1.dll bound test program (using zdll.lib)
minigzip_d.pdb Symbolic information for debugging minigzip_d.exe
zlib.h Install these files into the compilers' INCLUDE path to
zconf.h compile programs which use zlib.lib or zdll.lib
zdll.lib Install these files into the compilers' LIB path if linking
zdll.exp a compiled program to the zlib1.dll binary
zlib.lib Install these files into the compilers' LIB path to link zlib
zlib.pdb into compiled programs, without zlib1.dll runtime dependency
(zlib.pdb provides debugging info to the compile time linker)
zlib1.dll Install this binary shared library into the system PATH, or
the program's runtime directory (where the .exe resides)
zlib1.pdb Install in the same directory as zlib1.dll, in order to debug
an application crash using WinDbg or similar tools.
All .pdb files above are entirely optional, but are very useful to a developer
attempting to diagnose program misbehavior or a crash. Many additional
important files for developers can be found in the zlib127.zip source package
available from http://zlib.net/ - review that package's README file for details.
Acknowledgments:
The deflate format used by zlib was defined by Phil Katz. The deflate and
zlib specifications were written by L. Peter Deutsch. Thanks to all the
people who reported problems and suggested various improvements in zlib; they
are too numerous to cite here.

The code is thread safe, assuming that the standard library functions used are thread safe, such as memory allocation routines. It provides in-memory compression and decompression functions, including integrity checks of the uncompressed data. This version of the library supports only one compression method (deflation) but other algorithms may be added later with the same stream interface. .LP Compression can be done in a single step if the buffers are large enough or can be done by repeated calls of the compression function. In the latter case, the application must provide more input and/or consume the output (providing more output space) before each call. .LP The library also supports reading and writing files in .IR gzip (1) (.gz) format with an interface similar to that of stdio. .LP The library does not install any signal handler. The decoder checks the consistency of the compressed data, so the library should never crash even in the case of corrupted input. .LP All functions of the compression library are documented in the file .IR zlib.h . The distribution source includes examples of use of the library in the files .I test/example.c and .IR test/minigzip.c, as well as other examples in the .IR examples/ directory. .LP Changes to this version are documented in the file .I ChangeLog that accompanies the source. .LP .I zlib is built in to many languages and operating systems, including but not limited to Java, Python, .NET, PHP, Perl, Ruby, Swift, and Go. .LP An experimental package to read and write files in the .zip format, written on top of .I zlib by Gilles Vollant (info@winimage.com), is available at: .IP http://www.winimage.com/zLibDll/minizip.html and also in the .I contrib/minizip directory of the main .I zlib source distribution. .SH "SEE ALSO" The .I zlib web site can be found at: .IP http://zlib.net/ .LP The data format used by the .I zlib library is described by RFC (Request for Comments) 1950 to 1952 in the files: .IP http://tools.ietf.org/html/rfc1950 (for the zlib header and trailer format) .br http://tools.ietf.org/html/rfc1951 (for the deflate compressed data format) .br http://tools.ietf.org/html/rfc1952 (for the gzip header and trailer format) .LP Mark Nelson wrote an article about .I zlib for the Jan. 1997 issue of Dr. Dobb's Journal; a copy of the article is available at: .IP http://marknelson.us/1997/01/01/zlib-engine/ .SH "REPORTING PROBLEMS" Before reporting a problem, please check the .I zlib web site to verify that you have the latest version of .IR zlib ; otherwise, obtain the latest version and see if the problem still exists. Please read the .I zlib FAQ at: .IP http://zlib.net/zlib_faq.html .LP before asking for help. Send questions and/or comments to zlib@gzip.org, or (for the Windows DLL version) to Gilles Vollant (info@winimage.com). .SH AUTHORS AND LICENSE Version 1.3.1 .LP Copyright (C) 1995-2024 Jean-loup Gailly and Mark Adler .LP This software is provided 'as-is', without any express or implied warranty.

/*
The 'zlib' compression library provides in-memory compression and
decompression functions, including integrity checks of the uncompressed data.
This version of the library supports only one compression method (deflation)
but other algorithms will be added later and will have the same stream
interface.
Compression can be done in a single step if the buffers are large enough,
or can be done by repeated calls of the compression function. In the latter
case, the application must provide more input and/or consume the output
(providing more output space) before each call.
The compressed data format used by default by the in-memory functions is
the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
around a deflate stream, which is itself documented in RFC 1951.
The library also supports reading and writing files in gzip (.gz) format
with an interface similar to that of stdio using the functions that start
with "gz". The gzip format is different from the zlib format. gzip is a
gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
This library can optionally read and write gzip and raw deflate streams in
memory as well.
The zlib format was designed to be compact and fast for use in memory
and on communications channels. The gzip format was designed for single-
file compression on file systems, has a larger header than zlib to maintain
directory information, and uses a different, slower check method than zlib.
The library does not install any signal handler. The decoder checks
the consistency of the compressed data, so the library should never crash
even in the case of corrupted input.

The application must update next_in and avail_in when avail_in has dropped
to zero. It must update next_out and avail_out when avail_out has dropped
to zero. The application must initialize zalloc, zfree and opaque before
calling the init function. All other fields are set by the compression
library and must not be updated by the application.
The opaque value provided by the application will be passed as the first
parameter for calls of zalloc and zfree. This can be useful for custom
memory management. The compression library attaches no meaning to the
opaque value.
zalloc must return Z_NULL if there is not enough memory for the object.
If zlib is used in a multi-threaded application, zalloc and zfree must be
thread safe. In that case, zlib is thread-safe. When zalloc and zfree are
Z_NULL on entry to the initialization function, they are set to internal
routines that use the standard library functions malloc() and free().
On 16-bit systems, the functions zalloc and zfree must be able to allocate
exactly 65536 bytes, but will not be required to allocate more than this if
the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS, pointers
returned by zalloc for objects of exactly 65536 bytes *must* have their
offset normalized to zero. The default allocation function provided by this
library ensures this (see zutil.c). To reduce memory requirements and avoid
any allocation of 64K objects, at the expense of compression ratio, compile
the library with -DMAX_WBITS=14 (see zconf.h).
The fields total_in and total_out can be used for statistics or progress
reports. After compression, total_in holds the total size of the
uncompressed data and may be saved for use by the decompressor (particularly
if the decompressor wants to decompress everything in a single step).

ZEXTERN int ZEXPORT deflateInit(z_streamp strm, int level);
Initializes the internal stream state for compression. The fields
zalloc, zfree and opaque must be initialized before by the caller. If
zalloc and zfree are set to Z_NULL, deflateInit updates them to use default
allocation functions. total_in, total_out, adler, and msg are initialized.
The compression level must be Z_DEFAULT_COMPRESSION, or between 0 and 9:
1 gives best speed, 9 gives best compression, 0 gives no compression at all
(the input data is simply copied a block at a time). Z_DEFAULT_COMPRESSION
requests a default compromise between speed and compression (currently
equivalent to level 6).
deflateInit returns Z_OK if success, Z_MEM_ERROR if there was not enough
memory, Z_STREAM_ERROR if level is not a valid compression level, or
Z_VERSION_ERROR if the zlib library version (zlib_version) is incompatible
with the version assumed by the caller (ZLIB_VERSION). msg is set to null
if there is no error message. deflateInit does not perform any compression:
this will be done by deflate().
*/
ZEXTERN int ZEXPORT deflate(z_streamp strm, int flush);
/*
deflate compresses as much data as possible, and stops when the input
buffer becomes empty or the output buffer becomes full. It may introduce
some output latency (reading input without producing any output) except when
forced to flush.
The detailed semantics are as follows. deflate performs one or both of the
following actions:
- Compress more input starting at next_in and update next_in and avail_in
accordingly. If not all input can be processed (because there is not
enough room in the output buffer), next_in and avail_in are updated and
processing will resume at this point for the next call of deflate().
- Generate more output starting at next_out and update next_out and avail_out
accordingly. This action is forced if the parameter flush is non zero.
Forcing flush frequently degrades the compression ratio, so this parameter
should be set only when necessary. Some output may be provided even if
flush is zero.
Before the call of deflate(), the application should ensure that at least
one of the actions is possible, by providing more input and/or consuming more
output, and updating avail_in or avail_out accordingly; avail_out should
never be zero before the call. The application can consume the compressed
output when it wants, for example when the output buffer is full (avail_out
== 0), or after each call of deflate(). If deflate returns Z_OK and with
zero avail_out, it must be called again after making room in the output
buffer because there might be more output pending. See deflatePending(),
which can be used if desired to determine whether or not there is more output
in that case.
Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
decide how much data to accumulate before producing output, in order to
maximize compression.
If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
flushed to the output buffer and the output is aligned on a byte boundary, so
that the decompressor can get all input data available so far. (In
particular avail_in is zero after the call if enough output space has been
provided before the call.) Flushing may degrade compression for some
compression algorithms and so it should be used only when necessary. This
completes the current deflate block and follows it with an empty stored block
that is three bits plus filler bits to the next byte, followed by four bytes
(00 00 ff ff).
If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
output buffer, but the output is not aligned to a byte boundary. All of the
input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
This completes the current deflate block and follows it with an empty fixed
codes block that is 10 bits long. This assures that enough bytes are output
in order for the decompressor to finish the block before the empty fixed
codes block.
If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
seven bits of the current block are held to be written as the next byte after
the next deflate block is completed. In this case, the decompressor may not
be provided enough bits at this point in order to complete decompression of
the data provided so far to the compressor. It may need to wait for the next
block to be emitted. This is for advanced applications that need to control
the emission of deflate blocks.
If flush is set to Z_FULL_FLUSH, all output is flushed as with
Z_SYNC_FLUSH, and the compression state is reset so that decompression can
restart from this point if previous compressed data has been damaged or if
random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
compression.
If deflate returns with avail_out == 0, this function must be called again
with the same value of the flush parameter and more output space (updated
avail_out), until the flush is complete (deflate returns with non-zero
avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
avail_out is greater than six when the flush marker begins, in order to avoid
repeated flush markers upon calling deflate() again when avail_out == 0.
If the parameter flush is set to Z_FINISH, pending input is processed,
pending output is flushed and deflate returns with Z_STREAM_END if there was
enough output space. If deflate returns with Z_OK or Z_BUF_ERROR, this
function must be called again with Z_FINISH and more output space (updated
avail_out) but no more input data, until it returns with Z_STREAM_END or an
error. After deflate has returned Z_STREAM_END, the only possible operations
on the stream are deflateReset or deflateEnd.
Z_FINISH can be used in the first deflate call after deflateInit if all the
compression is to be done in a single step. In order to complete in one
call, avail_out must be at least the value returned by deflateBound (see
below). Then deflate is guaranteed to return Z_STREAM_END. If not enough
output space is provided, deflate will not return Z_STREAM_END, and it must
be called again as described above.
deflate() sets strm->adler to the Adler-32 checksum of all input read
so far (that is, total_in bytes). If a gzip stream is being generated, then
strm->adler will be the CRC-32 checksum of the input read so far. (See
deflateInit2 below.)
deflate() may update strm->data_type if it can make a good guess about
the input data type (Z_BINARY or Z_TEXT). If in doubt, the data is
considered binary. This field is only for information purposes and does not
affect the compression algorithm in any manner.
deflate() returns Z_OK if some progress has been made (more input
processed or more output produced), Z_STREAM_END if all input has been
consumed and all output has been produced (only when flush is set to
Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
if next_in or next_out was Z_NULL or the state was inadvertently written over
by the application), or Z_BUF_ERROR if no progress is possible (for example
avail_in or avail_out was zero). Note that Z_BUF_ERROR is not fatal, and
deflate() can be called again with more input and more output space to
continue compressing.

ZEXTERN int ZEXPORT inflateInit(z_streamp strm);
Initializes the internal stream state for decompression. The fields

read or consumed. The allocation of a sliding window will be deferred to
the first call of inflate (if the decompression does not complete on the

them to use default allocation functions. total_in, total_out, adler, and

there is no error message. inflateInit does not perform any decompression.
Actual decompression will be done by inflate(). So next_in, and avail_in,
next_out, and avail_out are unused and unchanged. The current
implementation of inflateInit() does not process any header information --
that is deferred until inflate() is called.
*/
ZEXTERN int ZEXPORT inflate(z_streamp strm, int flush);
/*
inflate decompresses as much data as possible, and stops when the input
buffer becomes empty or the output buffer becomes full. It may introduce
some output latency (reading input without producing any output) except when
forced to flush.
The detailed semantics are as follows. inflate performs one or both of the
following actions:
- Decompress more input starting at next_in and update next_in and avail_in
accordingly. If not all input can be processed (because there is not
enough room in the output buffer), then next_in and avail_in are updated
accordingly, and processing will resume at this point for the next call of
inflate().
- Generate more output starting at next_out and update next_out and avail_out
accordingly. inflate() provides as much output as possible, until there is
no more input data or no more space in the output buffer (see below about
the flush parameter).
Before the call of inflate(), the application should ensure that at least
one of the actions is possible, by providing more input and/or consuming more
output, and updating the next_* and avail_* values accordingly. If the
caller of inflate() does not provide both available input and available
output space, it is possible that there will be no progress made. The
application can consume the uncompressed output when it wants, for example
when the output buffer is full (avail_out == 0), or after each call of
inflate(). If inflate returns Z_OK and with zero avail_out, it must be
called again after making room in the output buffer because there might be
more output pending.
The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
output as possible to the output buffer. Z_BLOCK requests that inflate()
stop if and when it gets to the next deflate block boundary. When decoding
the zlib or gzip format, this will cause inflate() to return immediately
after the header and before the first block. When doing a raw inflate,
inflate() will go ahead and process the first block, and will return when it
gets to the end of that block, or when it runs out of data.
The Z_BLOCK option assists in appending to or combining deflate streams.
To assist in this, on return inflate() always sets strm->data_type to the
number of unused bits in the last byte taken from strm->next_in, plus 64 if
inflate() is currently decoding the last block in the deflate stream, plus
128 if inflate() returned immediately after decoding an end-of-block code or
decoding the complete header up to just before the first byte of the deflate
stream. The end-of-block will not be indicated until all of the uncompressed
data from that block has been written to strm->next_out. The number of
unused bits may in general be greater than seven, except when bit 7 of
data_type is set, in which case the number of unused bits will be less than
eight. data_type is set as noted here every time inflate() returns for all
flush options, and so can be used to determine the amount of currently
consumed input in bits.
The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
end of each deflate block header is reached, before any actual data in that
block is decoded. This allows the caller to determine the length of the
deflate block header for later use in random access within a deflate block.
256 is added to the value of strm->data_type when inflate() returns
immediately after reaching the end of the deflate block header.
inflate() should normally be called until it returns Z_STREAM_END or an
error. However if all decompression is to be performed in a single step (a
single call of inflate), the parameter flush should be set to Z_FINISH. In
this case all pending input is processed and all pending output is flushed;
avail_out must be large enough to hold all of the uncompressed data for the
operation to complete. (The size of the uncompressed data may have been
saved by the compressor for this purpose.) The use of Z_FINISH is not
required to perform an inflation in one step. However it may be used to
inform inflate that a faster approach can be used for the single inflate()
call. Z_FINISH also informs inflate to not maintain a sliding window if the
stream completes, which reduces inflate's memory footprint. If the stream
does not complete, either because not all of the stream is provided or not
enough output space is provided, then a sliding window will be allocated and
inflate() can be called again to continue the operation as if Z_NO_FLUSH had
been used.
In this implementation, inflate() always flushes as much output as
possible to the output buffer, and always uses the faster approach on the
first call. So the effects of the flush parameter in this implementation are
on the return value of inflate() as noted below, when inflate() returns early
when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
memory for a sliding window when Z_FINISH is used.
If a preset dictionary is needed after this call (see inflateSetDictionary
below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
strm->adler to the Adler-32 checksum of all output produced so far (that is,
total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
below. At the end of the stream, inflate() checks that its computed Adler-32
checksum is equal to that saved by the compressor and returns Z_STREAM_END
only if the checksum is correct.
inflate() can decompress and check either zlib-wrapped or gzip-wrapped
deflate data. The header type is detected automatically, if requested when
initializing with inflateInit2(). Any information contained in the gzip
header is not retained unless inflateGetHeader() is used. When processing
gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
produced so far. The CRC-32 is checked against the gzip trailer, as is the
uncompressed length, modulo 2^32.
inflate() returns Z_OK if some progress has been made (more input processed
or more output produced), Z_STREAM_END if the end of the compressed data has
been reached and all uncompressed output has been produced, Z_NEED_DICT if a
preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
corrupted (input stream not conforming to the zlib format or incorrect check
value, in which case strm->msg points to a string with a more specific
error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
next_in or next_out was Z_NULL, or the state was inadvertently written over
by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR
if no progress was possible or if there was not enough room in the output
buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
inflate() can be called again with more input and more output space to
continue decompressing. If Z_DATA_ERROR is returned, the application may
then call inflateSync() to look for a good compression block if a partial
recovery of the data is to be attempted.

/* Advanced functions */
/*
The following functions are needed only in some special applications.
*/
/*
ZEXTERN int ZEXPORT deflateInit2(z_streamp strm,
int level,
int method,
int windowBits,
int memLevel,
int strategy);
This is another version of deflateInit with more compression options. The
fields zalloc, zfree and opaque must be initialized before by the caller.
The method parameter is the compression method. It must be Z_DEFLATED in
this version of the library.
The windowBits parameter is the base two logarithm of the window size
(the size of the history buffer). It should be in the range 8..15 for this
version of the library. Larger values of this parameter result in better
compression at the expense of memory usage. The default value is 15 if
deflateInit is used instead.
For the current implementation of deflate(), a windowBits value of 8 (a
window size of 256 bytes) is not supported. As a result, a request for 8
will result in 9 (a 512-byte window). In that case, providing 8 to
inflateInit2() will result in an error when the zlib header with 9 is
checked against the initialization of inflate(). The remedy is to not use 8
with deflateInit2() with this initialization, or at least in that case use 9
with inflateInit2().
windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
determines the window size. deflate() will then generate raw deflate data
with no zlib header or trailer, and will not compute a check value.
windowBits can also be greater than 15 for optional gzip encoding. Add
16 to windowBits to write a simple gzip header and trailer around the
compressed data instead of a zlib wrapper. The gzip header will have no
file name, no extra data, no comment, no modification time (set to zero), no
header crc, and the operating system will be set to the appropriate value,
if the operating system was determined at compile time. If a gzip stream is
being written, strm->adler is a CRC-32 instead of an Adler-32.
For raw deflate or gzip encoding, a request for a 256-byte window is
rejected as invalid, since only the zlib header provides a means of
transmitting the window size to the decompressor.
The memLevel parameter specifies how much memory should be allocated
for the internal compression state. memLevel=1 uses minimum memory but is
slow and reduces compression ratio; memLevel=9 uses maximum memory for
optimal speed. The default value is 8. See zconf.h for total memory usage
as a function of windowBits and memLevel.
The strategy parameter is used to tune the compression algorithm. Use the
value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
string match), or Z_RLE to limit match distances to one (run-length
encoding). Filtered data consists mostly of small values with a somewhat
random distribution. In this case, the compression algorithm is tuned to
compress them better. The effect of Z_FILTERED is to force more Huffman
coding and less string matching; it is somewhat intermediate between
Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
strategy parameter only affects the compression ratio but not the
correctness of the compressed output even if it is not set appropriately.
Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
decoder for special applications.
deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
incompatible with the version assumed by the caller (ZLIB_VERSION). msg is
set to null if there is no error message. deflateInit2 does not perform any
compression: this will be done by deflate().
*/
ZEXTERN int ZEXPORT deflateSetDictionary(z_streamp strm,
const Bytef *dictionary,
uInt dictLength);
/*
Initializes the compression dictionary from the given byte sequence
without producing any compressed output. When using the zlib format, this
function must be called immediately after deflateInit, deflateInit2 or
deflateReset, and before any call of deflate. When doing raw deflate, this
function must be called either before any call of deflate, or immediately
after the completion of a deflate block, i.e. after all input has been
consumed and all output has been delivered when using any of the flush
options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH. The
compressor and decompressor must use exactly the same dictionary (see
inflateSetDictionary).
The dictionary should consist of strings (byte sequences) that are likely
to be encountered later in the data to be compressed, with the most commonly
used strings preferably put towards the end of the dictionary. Using a
dictionary is most useful when the data to be compressed is short and can be
predicted with good accuracy; the data can then be compressed better than
with the default empty dictionary.
Depending on the size of the compression data structures selected by
deflateInit or deflateInit2, a part of the dictionary may in effect be
discarded, for example if the dictionary is larger than the window size
provided in deflateInit or deflateInit2. Thus the strings most likely to be
useful should be put at the end of the dictionary, not at the front. In
addition, the current implementation of deflate will use at most the window
size minus 262 bytes of the provided dictionary.
Upon return of this function, strm->adler is set to the Adler-32 value
of the dictionary; the decompressor may later use this value to determine
which dictionary has been used by the compressor. (The Adler-32 value
applies to the whole dictionary even if only a subset of the dictionary is
actually used by the compressor.) If a raw deflate was requested, then the
Adler-32 value is not computed and strm->adler is not set.
deflateSetDictionary returns Z_OK if success, or Z_STREAM_ERROR if a
parameter is invalid (e.g. dictionary being Z_NULL) or the stream state is
inconsistent (for example if deflate has already been called for this stream
or if not at a block boundary for raw deflate). deflateSetDictionary does
not perform any compression: this will be done by deflate().

Z_NULL, then only the dictionary length is returned, and nothing is copied.
Similarly, if dictLength is Z_NULL, then it is not set.
deflateGetDictionary() may return a length less than the window size, even
when more than the window size in input has been provided. It may return up
to 258 bytes less in that case, due to how zlib's implementation of deflate
manages the sliding window and lookahead for matches, where matches can be
up to 258 bytes long. If the application needs the last window-size bytes of

*/
ZEXTERN int ZEXPORT deflateParams(z_streamp strm,
int level,

/*
Dynamically update the compression level and compression strategy. The
interpretation of level and strategy is as in deflateInit2(). This can be
used to switch between compression and straight copy of the input data, or
to switch to a different kind of input data requiring a different strategy.
If the compression approach (which is a function of the level) or the
strategy is changed, and if there have been any deflate() calls since the
state was initialized or reset, then the input available so far is
compressed with the old level and strategy using deflate(strm, Z_BLOCK).
There are three approaches for the compression levels 0, 1..3, and 4..9
respectively. The new level and strategy will take effect at the next call
of deflate().
If a deflate(strm, Z_BLOCK) is performed by deflateParams(), and it does
not have enough output space to complete, then the parameter change will not
take effect. In this case, deflateParams() can be called again with the
same parameters and more output space to try again.
In order to assure a change in the parameters on the first try, the
deflate stream should be flushed using deflate() with Z_BLOCK or other flush
request until strm.avail_out is not zero, before calling deflateParams().
Then no more input data should be provided before the deflateParams() call.
If this is done, the old level and strategy will be applied to the data
compressed before deflateParams(), and the new level and strategy will be
applied to the data compressed after deflateParams().
deflateParams returns Z_OK on success, Z_STREAM_ERROR if the source stream
state was inconsistent or if a parameter was invalid, or Z_BUF_ERROR if
there was not enough output space to complete the compression of the
available input data before a change in the strategy or approach. Note that
in the case of a Z_BUF_ERROR, the parameters are not changed. A return
value of Z_BUF_ERROR is not fatal, in which case deflateParams() can be

ZEXTERN int ZEXPORT inflateInit2(z_streamp strm,

This is another version of inflateInit with an extra parameter. The
fields next_in, avail_in, zalloc, zfree and opaque must be initialized
before by the caller.
The windowBits parameter is the base two logarithm of the maximum window
size (the size of the history buffer). It should be in the range 8..15 for
this version of the library. The default value is 15 if inflateInit is used
instead. windowBits must be greater than or equal to the windowBits value
provided to deflateInit2() while compressing, or it must be equal to 15 if
deflateInit2() was not used. If a compressed stream with a larger window
size is given as input, inflate() will return with the error code
Z_DATA_ERROR instead of trying to allocate a larger window.
windowBits can also be zero to request that inflate use the window size in
the zlib header of the compressed stream.
windowBits can also be -8..-15 for raw inflate. In this case, -windowBits
determines the window size. inflate() will then process raw deflate data,
not looking for a zlib or gzip header, not generating a check value, and not
looking for any check values for comparison at the end of the stream. This
is for use with other formats that use the deflate compressed data format
such as zip. Those formats provide their own check values. If a custom
format is developed using the raw deflate format for compressed data, it is
recommended that a check value such as an Adler-32 or a CRC-32 be applied to
the uncompressed data as is done in the zlib, gzip, and zip formats. For
most applications, the zlib format should be used as is. Note that comments
above on the use in deflateInit2() applies to the magnitude of windowBits.
windowBits can also be greater than 15 for optional gzip decoding. Add
32 to windowBits to enable zlib and gzip decoding with automatic header
detection, or add 16 to decode only the gzip format (the zlib format will
return a Z_DATA_ERROR). If a gzip stream is being decoded, strm->adler is a
CRC-32 instead of an Adler-32. Unlike the gunzip utility and gzread() (see
below), inflate() will *not* automatically decode concatenated gzip members.
inflate() will return Z_STREAM_END at the end of the gzip member. The state
would need to be reset to continue decoding a subsequent gzip member. This
*must* be done if there is more data after a gzip member, in order for the
decompression to be compliant with the gzip standard (RFC 1952).
inflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
memory, Z_VERSION_ERROR if the zlib library version is incompatible with the
version assumed by the caller, or Z_STREAM_ERROR if the parameters are
invalid, such as a null pointer to the structure. msg is set to null if
there is no error message. inflateInit2 does not perform any decompression
apart from possibly reading the zlib header if present: actual decompression
will be done by inflate(). (So next_in and avail_in may be modified, but
next_out and avail_out are unused and unchanged.) The current implementation
of inflateInit2() does not process any header information -- that is

If the upper value is -1 and the lower value is non-zero, then inflate is in
the middle of a stored block, with the lower value equaling the number of
bytes from the input remaining to copy. If the upper value is not -1, then
it is the number of bits back from the current bit position in the input of
the code (literal or length/distance pair) currently being processed. In
that case the lower value is the number of bytes already emitted for that

As inflate() processes the gzip stream, head->done is zero until the header
is completed, at which time head->done is set to one. If a zlib stream is
being decoded, then head->done is set to -1 to indicate that there will be
no gzip header information forthcoming. Note that Z_BLOCK or Z_TREES can be
used to force inflate() to return immediately after header processing is
complete and before any actual data is decompressed.
The text, time, xflags, and os fields are filled in with the gzip header
contents. hcrc is set to true if there is a header CRC. (The header CRC
was valid if done is set to one.) If extra is not Z_NULL, then extra_max
contains the maximum number of bytes to write to extra. Once done is true,
extra_len contains the actual extra field length, and extra contains the
extra field, or that field truncated if extra_max is less than extra_len.
If name is not Z_NULL, then up to name_max characters are written there,
terminated with a zero unless the length is greater than name_max. If
comment is not Z_NULL, then up to comm_max characters are written there,
terminated with a zero unless the length is greater than comm_max. When any
of extra, name, or comment are not Z_NULL and the respective field is not
present in the header, then that field is set to Z_NULL to signal its
absence. This allows the use of deflateSetHeader() with the returned
structure to duplicate the header. However if those fields are set to
allocated memory, then the application will need to save those pointers
elsewhere so that they can be eventually freed.
If inflateGetHeader is not used, then the header information is simply
discarded. The header is always checked for validity, including the header
CRC if present. inflateReset() will reset the process to discard the header
information. The application would need to call inflateGetHeader() again to
retrieve the header from the next gzip stream.

ZEXTERN int ZEXPORT inflateBack(z_streamp strm,
in_func in, void FAR *in_desc,
out_func out, void FAR *out_desc);
/*
inflateBack() does a raw inflate with a single call using a call-back
interface for input and output. This is potentially more efficient than
inflate() for file i/o applications, in that it avoids copying between the
output and the sliding window by simply making the window itself the output
buffer. inflate() can be faster on modern CPUs when used with large
buffers. inflateBack() trusts the application to not change the output
buffer passed by the output function, at least until inflateBack() returns.
inflateBackInit() must be called first to allocate the internal state
and to initialize the state with the user-provided window buffer.
inflateBack() may then be used multiple times to inflate a complete, raw
deflate stream with each call. inflateBackEnd() is then called to free the
allocated state.
A raw deflate stream is one with no zlib or gzip header or trailer.
This routine would normally be used in a utility that reads zip or gzip
files and writes out uncompressed files. The utility would decode the
header and process the trailer on its own, hence this routine expects only
the raw deflate stream to decompress. This is different from the default
behavior of inflate(), which expects a zlib header and trailer around the
deflate stream.
inflateBack() uses two subroutines supplied by the caller that are then
called by inflateBack() for input and output. inflateBack() calls those
routines until it reads a complete deflate stream and writes out all of the
uncompressed data, or until it encounters an error. The function's
parameters and return types are defined above in the in_func and out_func
typedefs. inflateBack() will call in(in_desc, &buf) which should return the
number of bytes of provided input, and a pointer to that input in buf. If
there is no input available, in() must return zero -- buf is ignored in that
case -- and inflateBack() will return a buffer error. inflateBack() will
call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
out() should return zero on success, or non-zero on failure. If out()
returns non-zero, inflateBack() will return with an error. Neither in() nor
out() are permitted to change the contents of the window provided to
inflateBackInit(), which is also the buffer that out() uses to write from.
The length written by out() will be at most the window size. Any non-zero
amount of input may be provided by in().
For convenience, inflateBack() can be provided input on the first call by
setting strm->next_in and strm->avail_in. If that input is exhausted, then
in() will be called. Therefore strm->next_in must be initialized before
calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
must also be initialized, and then if strm->avail_in is not zero, input will
initially be taken from strm->next_in[0 .. strm->avail_in - 1].
The in_desc and out_desc parameters of inflateBack() is passed as the
first parameter of in() and out() respectively when they are called. These
descriptors can be optionally used to pass any information that the caller-
supplied in() and out() functions need to do their job.
On return, inflateBack() will set strm->next_in and strm->avail_in to
pass back any unused input that was provided by the last in() call. The
return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
if in() or out() returned an error, Z_DATA_ERROR if there was a format error
in the deflate stream (in which case strm->msg is set to indicate the nature
of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
In the case of Z_BUF_ERROR, an input or output error can be distinguished
using strm->next_in which will be Z_NULL only if in() returned an error. If
strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
non-zero. (in() will always be called before out(), so strm->next_in is
assured to be defined if out() returns non-zero.) Note that inflateBack()
cannot return Z_OK.

ZEXTERN gzFile ZEXPORT gzopen(const char *path, const char *mode);
Open the gzip (.gz) file at path for reading and decompressing, or
compressing and writing. The mode parameter is as in fopen ("rb" or "wb")
but can also include a compression level ("wb9") or a strategy: 'f' for
filtered data as in "wb6f", 'h' for Huffman-only compression as in "wb1h",
'R' for run-length encoding as in "wb1R", or 'F' for fixed code compression
as in "wb9F". (See the description of deflateInit2 for more information
about the strategy parameter.) 'T' will request transparent writing or
appending with no compression and not using the gzip format.
"a" can be used instead of "w" to request that the gzip stream that will
be written be appended to the file. "+" will result in an error, since
reading and writing to the same gzip file is not supported. The addition of
"x" when writing will create the file exclusively, which fails if the file
already exists. On systems that support it, the addition of "e" when
reading or writing will set the flag to close the file on an execve() call.
These functions, as well as gzip, will read and decode a sequence of gzip
streams in a file. The append function of gzopen() can be used to create
such a file. (Also see gzflush() for another way to do this.) When
appending, gzopen does not test whether the file begins with a gzip stream,
nor does it look for the end of the gzip streams to begin appending. gzopen
will simply append a gzip stream to the existing file.
gzopen can be used to read a file which is not in gzip format; in this
case gzread will directly read from the file without decompression. When
reading, this will be detected automatically by looking for the magic two-
byte gzip header.
gzopen returns NULL if the file could not be opened, if there was
insufficient memory to allocate the gzFile state, or if an invalid mode was
specified (an 'r', 'w', or 'a' was not provided, or '+' was provided).
errno can be checked to determine if the reason gzopen failed was that the
file could not be opened.

The next call of gzclose on the returned gzFile will also close the file
descriptor fd, just like fclose(fdopen(fd, mode)) closes the file descriptor
fd. If you want to keep fd open, use fd = dup(fd_keep); gz = gzdopen(fd,
mode);. The duplicated descriptor should be saved to avoid a leak, since
gzdopen does not close fd if it fails. If you are using fileno() to get the
file descriptor from a FILE *, then you will have to use dup() to avoid
double-close()ing the file descriptor. Both gzclose() and fclose() will
close the associated file descriptor, so they need to have different file
descriptors.
gzdopen returns NULL if there was insufficient memory to allocate the
gzFile state, if an invalid mode was specified (an 'r', 'w', or 'a' was not

to read, looking for another gzip stream. Any number of gzip streams may be
concatenated in the input file, and will all be decompressed by gzread().
If something other than a gzip stream is encountered after a gzip stream,
that remaining trailing garbage is ignored (and no error is returned).
gzread can be used to read a gzip file that is being concurrently written.
Upon reaching the end of the input, gzread will return with the available
data. If the error code returned by gzerror is Z_OK or Z_BUF_ERROR, then
gzclearerr can be used to clear the end of file indicator in order to permit
gzread to be tried again. Z_OK indicates that a gzip stream was completed

of an incomplete gzip stream. This error is deferred until gzclose(), which
will return Z_BUF_ERROR if the last gzread ended in the middle of a gzip
stream. Alternatively, gzerror can be used before gzclose to detect this
case.
gzread returns the number of uncompressed bytes actually read, less than

gzip stream is completed in the output. If gzwrite() is called again, a new
gzip stream will be started in the output. gzread() is able to read such
concatenated gzip streams.
gzflush should be called only when strictly necessary because it will
degrade compression if called too often.

/*
ZEXTERN z_off_t ZEXPORT gzseek(gzFile file,
z_off_t offset, int whence);
Set the starting position to offset relative to whence for the next gzread
or gzwrite on file. The offset represents a number of bytes in the
uncompressed data stream. The whence parameter is defined as in lseek(2);
the value SEEK_END is not supported.
If the file is opened for reading, this function is emulated but can be
extremely slow. If the file is opened for writing, only forward seeks are
supported; gzseek then compresses a sequence of zeroes up to the new
starting position.
gzseek returns the resulting offset location as measured in bytes from
the beginning of the uncompressed stream, or -1 in case of error, in
particular if the file is opened for writing and the new starting position
would be before the current position.
*/
ZEXTERN int ZEXPORT gzrewind(gzFile file);
/*
Rewind file. This function is supported only for reading.
gzrewind(file) is equivalent to (int)gzseek(file, 0L, SEEK_SET).
*/
/*
ZEXTERN z_off_t ZEXPORT gztell(gzFile file);
Return the starting position for the next gzread or gzwrite on file.
This position represents a number of bytes in the uncompressed data stream,
and is zero when starting, even if appending or reading a gzip stream from
the middle of a file using gzdopen().
gztell(file) is equivalent to gzseek(file, 0L, SEEK_CUR)
*/
/*
ZEXTERN z_off_t ZEXPORT gzoffset(gzFile file);
Return the current compressed (actual) read or write offset of file. This
offset includes the count of bytes that precede the gzip stream, for example
when appending or when using gzdopen() for reading. When reading, the
offset does not include as yet unused buffered input. This information can
be used for a progress indicator. On error, gzoffset() returns -1.
*/
ZEXTERN int ZEXPORT gzeof(gzFile file);
/*
Return true (1) if the end-of-file indicator for file has been set while
reading, false (0) otherwise. Note that the end-of-file indicator is set
only if the read tried to go past the end of the input, but came up short.
Therefore, just like feof(), gzeof() may return false even if there is no
more data to read, in the event that the last read request was for the exact
number of bytes remaining in the input file. This will happen if the input
file size is an exact multiple of the buffer size.
If gzeof() returns true, then the read functions will return no more data,
unless the end-of-file indicator is reset by gzclearerr() and the input file
has grown since the previous end of file was detected.
*/
ZEXTERN int ZEXPORT gzdirect(gzFile file);
/*
Return true (1) if file is being copied directly while reading, or false
(0) if file is a gzip stream being decompressed.
If the input file is empty, gzdirect() will return true, since the input
does not contain a gzip stream.
If gzdirect() is used immediately after gzopen() or gzdopen() it will
cause buffers to be allocated to allow reading the file to determine if it
is a gzip file. Therefore if gzbuffer() is used, it should be called before
gzdirect().
When writing, gzdirect() returns true (1) if transparent writing was
requested ("wT" for the gzopen() mode), or false (0) otherwise. (Note:
gzdirect() is not needed when writing. Transparent writing must be
explicitly requested, so the application already knows the answer. When
linking statically, using gzdirect() will include all of the zlib code for
gzip file reading and decompression, which may not be desired.)
*/
ZEXTERN int ZEXPORT gzclose(gzFile file);
/*
Flush all pending output for file, if necessary, close file and
deallocate the (de)compression state. Note that once file is closed, you
cannot call gzerror with file, since its structures have been deallocated.
gzclose must not be called more than once on the same file, just as free
must not be called more than once on the same allocation.
gzclose will return Z_STREAM_ERROR if file is not valid, Z_ERRNO on a
file operation error, Z_MEM_ERROR if out of memory, Z_BUF_ERROR if the
last read ended in the middle of a gzip stream, or Z_OK on success.

/*
Same as gzclose(), but gzclose_r() is only for use when reading, and
gzclose_w() is only for use when writing or appending. The advantage to
using these instead of gzclose() is that they avoid linking in zlib
compression or decompression code that is not used when only reading or only
writing respectively. If gzclose() is used, then both compression and
decompression code will be included the application when linking to a static
zlib library.
*/
ZEXTERN const char * ZEXPORT gzerror(gzFile file, int *errnum);
/*
Return the error message for the last error which occurred on file.
errnum is set to zlib error number. If an error occurred in the file system
and not in the compression library, errnum is set to Z_ERRNO and the
application may consult errno to get the exact error code.
The application must not modify the returned string. Future calls to
this function may invalidate the previously returned string. If file is
closed, then the string previously returned by gzerror will no longer be
available.
gzerror() should be used to distinguish errors from end-of-file for those
functions above that do not distinguish those cases in their return values.

much faster.

each, adler1 and adler2. adler32_combine() returns the Adler-32 checksum of
seq1 and seq2 concatenated, requiring only adler1, adler2, and len2. Note
that the z_off_t type (like off_t) is a signed integer. If len2 is
negative, the result has no meaning or utility.

If buf is Z_NULL, this function returns the required initial value for the
crc. Pre- and post-conditioning (one's complement) is performed within this
function so it shouldn't be done by the application.

Allocates a new value of the specified type. Ownership is
transfered to the caller, who must eventually free it by passing it

It is allowed, not required. It is allowed so that JSON can be safely
embedded in HTML, which can freak out when seeing strings containing
"</". JSON tolerates "<\/" for this reason.

Tokenizes an input string on a given separator. Inputs are:
- (inp) = is a pointer to the pointer to the start of the input.
- (separator) = the separator character
- (end) = a pointer to NULL. i.e. (*end == NULL)
This function scans *inp for the given separator char or a NUL char.
Successive separators at the start of *inp are skipped. The effect is
that, when this function is called in a loop, all neighboring
separators are ignored. e.g. the string "aa.bb...cc" will tokenize to
the list (aa,bb,cc) if the separator is '.' and to (aa.,...cc) if the
separator is 'b'.
Returns 0 (false) if it finds no token, else non-0 (true).
Output:
- (*inp) will be set to the first character of the next token.
- (*end) will point to the one-past-the-end point of the token.
If (*inp == *end) then the end of the string has been reached
without finding a token.
Post-conditions:
- (*end == *inp) if no token is found.
- (*end > *inp) if a token is found.
It is intolerant of NULL values for (inp, end), and will assert() in
debug builds if passed NULL as either parameter.

/** @page page_cson cson JSON API
cson (pronounced "season") is an object-oriented C API for generating
and consuming JSON (http://www.json.org) data.
Its main claim to fame is that it can parse JSON from, and output it
to, damned near anywhere. The i/o routines use a callback function to
fetch/emit JSON data, allowing clients to easily plug in their own
implementations. Implementations are provided for string- and
FILE-based i/o.

It is only lightly tested with long double, and when using
long double the memory requirements for such values goes
up.
Note that by default cson uses C-API defaults for numeric
precision. To use a custom precision throughout the library, one
needs to define the macros CSON_DOUBLE_T_SFMT and/or
CSON_DOUBLE_T_PFMT macros to include their desired precision, and
must build BOTH cson AND the client using these same values. For
example:
@code
#define CSON_DOUBLE_T_PFMT ".8Lf" // for Modified Julian Day values
#define HAVE_LONG_DOUBLE

compilation warnings in 32-bit builds even though the code

also use the same value for this macro. If i knew a halfway reliable

/** @struct cson_value
The core value type of this API. It is opaque to clients, and
only the cson public API should be used for setting or
inspecting their values.
This class is opaque because stack-based usage can easily cause
leaks if one does not intimately understand the underlying
internal memory management (which sometimes changes).
It is (as of 20110323) legal to insert a given value instance into
multiple containers (they will share ownership using reference
counting) as long as those insertions do not cause cycles. However,
be very aware that such value re-use uses a reference to the
original copy, meaning that if its value is changed once, it is
changed everywhere. Also beware that multi-threaded write
operations on such references leads to undefined behaviour.
PLEASE read the ACHTUNGEN below...
ACHTUNG #1:
cson_values MUST NOT form cycles (e.g. via object or array
entries).
Not abiding th Holy Law Of No Cycles will lead to double-frees and
the like (i.e. undefined behaviour, likely crashes due to infinite
recursion or stepping on invalid (freed) pointers).
ACHTUNG #2:
ALL cson_values returned as non-const cson_value pointers from any
public functions in the cson API are to be treated as if they are
heap-allocated, and MUST be freed by client by doing ONE of:
- Passing it to cson_value_free().
- Adding it to an Object or Array, in which case the object/array
takes over ownership. As of 20110323, a value may be inserted into
a single container multiple times, or into multiple containers,
in which case they all share ownership (via reference counting)
of the original value (meaning any changes to it are visible in
all references to it).
Each call to cson_value_new_xxx() MUST eventually be followed up
by one of those options.
Some cson_value_new_XXX() implementations do not actually allocate
memory, but this is an internal implementation detail. Client code
MUST NOT rely on this behaviour and MUST treat each object
returned by such a function as if it was a freshly-allocated copy
(even if their pointer addresses are the same).
ACHTUNG #3:
Note that ACHTUNG #2 tells us that we must always free (or transfer
ownership of) all pointers returned bycson_value_new_xxx(), but
that two calls to (e.g.) cson_value_new_bool(1) will (or might)
return the same address. The client must not rely on the
"non-allocation" policy of such special cases, and must pass each
returned value to cson_value_free(), even if two of them have the
same address. Some special values (e.g. null, true, false, integer
0, double 0.0, and empty strings) use shared copies and in other
places reference counting is used internally to figure out when it
is safe to destroy an object.

/** @var cson_rc
Deprecated: clients are encouraged to use the CSON_RC_xxx values
which correspond to cson_rc.xxx, as those are more efficient. Some
docs and code may still refer to cson_rc, though.
This object defines the error codes used by cson.
Library routines which return int values almost always return a
value from this structure. None of the members in this struct have
published values except for the OK member, which has the value 0.
All other values might be incidentally defined where clients
can see them, but the numbers might change from release to
release, so clients should only use the symbolic names.
Client code is expected to access these values via the shared
cson_rc object, and use them as demonstrated here:
@code
int rc = cson_some_func(...);
if( 0 == rc ) {...success...}
else if( cson_rc.ArgError == rc ) { ... some argument was wrong ... }
else if( cson_rc.AllocError == rc ) { ... allocation error ... }
...
@endcode
Or with the preferred/newer method:
@code
int rc = cson_some_func(...);
switch(rc){
case 0: ...success...;
case CSON_RC_ArgError: ... some argument was wrong ...
case CSON_RC_AllocError: ... allocation error ...
...
}
@endcode
The entries named Parse_XXX are generally only returned by
cson_parse() and friends.

is not useful with non-blocking readers).

returns, so the implementation must copy or ignore the data, but not
hold a copy of the src pointer.

These functions are called relatively often during the JSON-output

Reads JSON-formatted string data (in ASCII, UTF8, or UTF16), using the
src function to fetch all input. This function fetches each input character
from the source function, which is calls like src(srcState, buffer, bufferSize),
and processes them. If anything is not JSON-kosher then this function
fails and returns one of the non-0 cson_rc codes.
This function is only intended to read root nodes of a JSON tree, either
a single object or a single array, containing any number of child elements.
On success, *tgt is assigned the value of the root node of the
JSON input, and the caller takes over ownership of that memory.
On error, *tgt is not modified and the caller need not do any
special cleanup, except possibly for the input source.
The opt argument may point to an initialized cson_parse_opt object
which contains any settings the caller wants. If it is NULL then
default settings (the values defined in cson_parse_opt_empty) are
used.
The info argument may be NULL. If it is not NULL then the parser
populates it with information which is useful in error
reporting. Namely, it contains the line/column of parse errors.
The srcState argument is ignored by this function but is passed on to src,
so any output-destination-specific state can be stored there and accessed
via the src callback.
Non-parse error conditions include:
- (!tgt) or !src: CSON_RC_ArgError
- CSON_RC_AllocError can happen at any time during the input phase
Here's a complete example of using a custom input source:
@code
// Internal type to hold state for a JSON input string.
typedef struct
{
char const * str; // start of input string
char const * pos; // current internal cursor position
char const * end; // logical EOF (one-past-the-end)

else if( !*n ) return CSON_RC_RangeError;
for( i = 0;
(i < *n) && (ss->pos < ss->end);
++i, ++ss->pos, ++tgt )
{
*tgt = *ss->pos;
}
*n = i;
return 0;
}
...
// Now use StringSource together with cson_parse()
StringSource ss;
cson_value * root = NULL;
char const * json = "{\"k1\":123}";
ss.str = ss.pos = json;
ss.end = json + strlen(json);
int rc = cson_parse( &root, cson_data_source_StringSource, &ss, NULL, NULL );

to it. If tgt is NULL then this function has no side-effects but
will return 0 if the given path is found within the object, so it can be used
to test for existence without fetching it.
Returns 0 if it finds an entry, CSON_RC_NotFoundError if it finds
no item, and any other non-zero error code on a "real" error. Errors include:
- obj or path are NULL: CSON_RC_ArgError
- separator is 0, or path is an empty string or contains only
separator characters: CSON_RC_RangeError
- There is an upper limit on how long a single path component may
be (some "reasonable" internal size), and CSON_RC_RangeError is
returned if that length is violated.
Limitations:
- It has no way to fetch data from arrays this way. i could
imagine, e.g., a path of "subobj.subArray.0" for
subobj.subArray[0], or "0.3.1" for [0][3][1]. But i'm too
lazy/tired to add this.
Example usage:
Assume we have a JSON structure which abstractly looks like:
@code
{"subobj":{"subsubobj":{"myValue":[1,2,3]}}}
@endcode
Out goal is to get the value of myValue. We can do that with:
@code
cson_value * v = NULL;
int rc = cson_object_fetch_sub( object, &v, "subobj.subsubobj.myValue", '.' );
@endcode
Note that because keys in JSON may legally contain a '.', the
separator must be specified by the caller. e.g. the path
"subobj/subsubobj/myValue" with separator='/' is equivalent the
path "subobj.subsubobj.myValue" with separator='.'. The value of 0
is not legal as a separator character because we cannot
distinguish that use from the real end-of-string without requiring
the caller to also pass in the length of the string.
Multiple successive separators in the list are collapsed into a
single separator for parsing purposes. e.g. the path "a...b...c"
(separator='.') is equivalent to "a.b.c".

object or array to contain the shared value. This can be used to
ensure the lifetime of the shared value instance. Each sharing
point adds a reference and simply passed the value to
cson_value_free() when they're done. The object will be kept alive
for other sharing points which added a reference.
Normally any such value handles would be invalidated when the
parent container(s) is/are cleaned up, but this function can be
used to effectively delay the cleanup.
This function, at its lowest level, increments the value's
reference count by 1.
To decrement the reference count, pass the value to
cson_value_free(), after which the value must be considered, from
the perspective of that client code, to be destroyed (though it
will not be if there are still other live references to
it). cson_value_free() will not _actually_ destroy the value until
its reference count drops to 0.
Returns 0 on success. The only error conditions are if v is NULL
(CSON_RC_ArgError) or if the reference increment would overflow
(CSON_RC_RangeError). In theory a client would get allocation
errors long before the reference count could overflow (assuming
those reference counts come from container insertions, as opposed
to via this function).
Insider notes which clients really need to know:
For shared/constant value instances, such as those returned by
cson_value_true() and cson_value_null(), this function has no side
effects - it does not actually modify the reference count because
(A) those instances are shared across all client code and (B) those
objects are static and never get cleaned up. However, that is an
implementation detail which client code should not rely on. In
other words, if you call cson_value_add_reference() 3 times using
the value returned by cson_value_true() (which is incidentally a
shared cson_value instance), you must eventually call
cson_value_free() 3 times to (semantically) remove those
references. However, internally the reference count for that
specific cson_value instance will not be modified and those
objects will never be freed (they're stack-allocated).
It might be interesting to note that newly-created objects
have a reference count of 0 instead of 1. This is partly because
if the initial reference is counted then it makes ownership
problematic when inserting values into containers. e.g. consider the
following code:
@code
// ACHTUNG: this code is hypothetical and does not reflect
// what actually happens!
cson_value * v =
cson_value_new_integer( 42 ); // v's refcount = 1
cson_array_append( myArray, v ); // v's refcount = 2
@endcode
If that were the case, the client would be forced to free his own
reference after inserting it into the container (which is a bit
counter-intuitive as well as intrusive). It would look a bit like
the following and would have to be done after every create/insert
operation:
@code
// ACHTUNG: this code is hypothetical and does not reflect
// what actually happens!
cson_array_append( myArray, v ); // v's refcount = 2
cson_value_free( v ); // v's refcount = 1
@endcode
(As i said: it's counter-intuitive and intrusive.)
Instead, values start with a refcount of 0 and it is only increased
when the value is added to an object/array container or when this
function is used to manually increment it. cson_value_free() treats
a refcount of 0 or 1 equivalently, destroying the value
instance. The only semantic difference between 0 and 1, for
purposes of cleaning up, is that a value with a non-0 refcount has
been had its refcount adjusted, whereas a 0 refcount indicates a
fresh, "unowned" reference.

/**
Deeply copies a JSON value, be it an object/array or a "plain"
value (e.g. number/string/boolean). If cv is not NULL then this
function makes a deep clone of it and returns that clone. Ownership
of the clone is identical t transfered to the caller, who must
eventually free the value using cson_value_free() or add it to a
container object/array to transfer ownership to the container. The
returned object will be of the same logical type as orig.
ACHTUNG: if orig contains any cyclic references at any depth level
this function will endlessly recurse. (Having _any_ cyclic
references violates this library's requirements.)
Returns NULL if orig is NULL or if cloning fails. Assuming that
orig is in a valid state, the only "likely" error case is that an
allocation fails while constructing the clone. In other words, if
cloning fails due to something other than an allocation error then
either orig is in an invalid state or there is a bug.
When this function clones Objects or Arrays it shares any immutable
values (including object keys) between the parent and the
clone. Mutable values (Objects and Arrays) are copied, however.
For example, if we clone:
@code
{ a: 1, b: 2, c:["hi"] }
@endcode
The cloned object and the array "c" would be a new Object/Array
instances but the object keys (a,b,b) and the values of (a,b), as
well as the string value within the "c" array, would be shared
between the original and the clone. The "c" array itself would be
deeply cloned, such that future changes to the clone are not
visible to the parent, and vice versa, but immutable values within
the array are shared (in this case the string "hi"). The
justification for this heuristic is that immutable values can never
be changed, so there is no harm in sharing them across
clones. Additionally, such types can never contribute to cycles in
a JSON tree, so they are safe to share this way. Objects and
Arrays, on the other hand, can be modified later and can contribute
to cycles, and thus the clone needs to be an independent instance.
Note, however, that if this function directly passed a
non-Object/Array, that value is deeply cloned. The sharing
behaviour only applies when traversing Objects/Arrays.

If a given value is reference counted and encountered multiple

visited already and whether it should or should not be counted, so
we pessimistically count them even though the _might_ not really

references live).
This function returns 0 if any of the following are true:
- v is NULL
- v is one of the special singleton values (null, bools, empty
string, int 0, double 0.0)
All other values require an allocation, and this will return their
total memory cost, including the cson-specific internals and the
native value(s).
Note that because arrays and objects might have more internal slots
allocated than used, the alloced size of a container does not
necessarily increase when a new item is inserted into it. An interesting
side-effect of this is that when cson_clone()ing an array or object, the
size of the clone can actually be less than the original.

to be the same as the underlying query fields, but the order
of the keys in the "rows" might be different and might in fact
change when passed through different JSON implementations,
depending on how they implement object key/value pairs.
On success it returns 0 and assigns *tgt to a newly-allocated
JSON object tree (using the above structure), which the caller owns.
If the query returns no rows, the "rows" value will be an empty
array, as opposed to null.
On error non-0 is returned and *tgt is not modified.
The error code cson_rc.IOError is used to indicate a db-level
error, and cson_rc.TypeError is returned if sqlite3_column_count(st)
returns 0 or less (indicating an invalid or non-SELECT statement).
The JSON data types are determined by the column type as reported
by sqlite3_column_type():
SQLITE_INTEGER: integer
SQLITE_FLOAT: double
SQLITE_TEXT or SQLITE_BLOB: string, and this will only work if
the data is UTF8 compatible.
If the db returns a literal or SQL NULL for a value it is converted
to a JSON null. If it somehow finds a column type it cannot handle,
the value is also converted to a NULL in the output.

* - Completion?
*
* Unix/termios
* ------------
* List of escape sequences used by this program, we do everything just
* a few sequences. In order to be so cheap we may have some
* flickering effect with some slow terminal, but the lesser sequences
* the more compatible.
*
* EL (Erase Line)
* Sequence: ESC [ 0 K
* Effect: clear from cursor to end of line
*
* CUF (CUrsor Forward)
* Sequence: ESC [ n C
* Effect: moves cursor forward n chars
*
* CR (Carriage Return)
* Sequence: \r
* Effect: moves cursor to column 1
*
* The following are used to clear the screen: ESC [ H ESC [ 2 J
* This is actually composed of two sequences:
*
* cursorhome
* Sequence: ESC [ H
* Effect: moves the cursor to upper left corner
*
* ED2 (Clear entire screen)
* Sequence: ESC [ 2 J
* Effect: clear the whole screen
*
* == For highlighting control characters, we also use the following two ==
* SO (enter StandOut)
* Sequence: ESC [ 7 m
* Effect: Uses some standout mode such as reverse video
*
* SE (Standout End)
* Sequence: ESC [ 0 m
* Effect: Exit standout mode
*
* == Only used if TIOCGWINSZ fails ==
* DSR/CPR (Report cursor position)
* Sequence: ESC [ 6 n
* Effect: reports current cursor position as ESC [ NNN ; MMM R
*
* == Only used in multiline mode ==
* CUU (Cursor Up)
* Sequence: ESC [ n A
* Effect: moves cursor up n chars.
*
* CUD (Cursor Down)
* Sequence: ESC [ n B
* Effect: moves cursor down n chars.
*
* win32/console
* -------------
* If __MINGW32__ is defined, the win32 console API is used.
* This could probably be made to work for the msvc compiler too.
* This support based in part on work by Jon Griffiths.

***********************************************************************
This is a JS Worker file for use with the pikchr wasm build. It
loads the pikchr wasm module and offers access to it via the Worker
message-passing interface.
Because we can have only a single message handler, as opposed to an
arbitrary number of discrete event listeners like with DOM elements,
we have to define a lower-level message API. Messages abstractly
look like:
{ type: string, data: type-specific value }
Where 'type' is used for dispatching and 'data' is a
'type'-dependent value.
The 'type' values expected by each side of the main/worker
connection vary. The types are described below but subject to
change at any time as this experiment evolves.
Main-to-Worker message types:
- pikchr: data=pikchr-format text to render or an object:
{
pikchr: source code for the pikchr,
darkMode: boolean true to adjust colors for a dark color scheme,
cssClass: CSS class name to add to the SVG
}
Workers-to-Main types
- stdout, stderr: indicate stdout/stderr output from the wasm
layer. The data property is the string of the output, noting
that the emscripten binding emits these one line at a time. Thus,
if a C-side puts() emits multiple lines in a single call, the JS
side will see that as multiple calls. Example:
{type:'stdout', data: 'Hi, world.'}
- module: Status text. This is intended to alert the main thread
about module loading status so that, e.g., the main thread can
update a progress widget and DTRT when the module is finished
loading and available for work. Status messages come in the form
{type:'module', data:{
type:'status',
data: {text:string|null, step:1-based-integer}
}
with an incrementing step value for each subsequent message. When
the module loading is complete, a message with a text value of
null is posted.
- pikchr:
{type: 'pikchr',
data:{
pikchr: input text,
result: rendered result (SVG on success, HTML on error),
isError: bool, true if .pikchr holds an error report,
flags: integer: flags used to configure the pikchr rendering,
width: if !isError, width (integer pixels) of the SVG,
height: if !isError, height (integer pixels) of the SVG
}
}

We have no way of knowing in advance how many steps will
be processed/posted, so creating a "percentage done" view is
not really practical. One can be approximated by giving it a
current value of message.step and max value of message.step+1,
though.
When work is finished, a message with a text value of null is
submitted.
After a message with text==null is posted, the module may later
post messages about fatal problems, e.g. an exit() being

status messages not be outright removed from the DOM when
text==null, and that they instead be hidden until/unless

****************************************************************************
**
** This software translates a PIC-inspired diagram language into SVG.
**
** PIKCHR (pronounced like "picture") is *mostly* backwards compatible
** with legacy PIC, though some features of legacy PIC are removed
** (for example, the "sh" command is removed for security) and
** many enhancements are added.
**
** PIKCHR is designed for use in an internet facing web environment.
** In particular, PIKCHR is designed to safely generate benign SVG from
** source text that provided by a hostile agent.
**
** This code was originally written by D. Richard Hipp using documentation
** from prior PIC implementations but without reference to prior code.
** All of the code in this project is original.
**
** This file implements a C-language subroutine that accepts a string
** of PIKCHR language text and generates a second string of SVG output that
** renders the drawing defined by the input. Space to hold the returned
** string is obtained from malloc() and should be freed by the caller.
** NULL might be returned if there is a memory allocation error.
**
** If there are errors in the PIKCHR input, the output will consist of an
** error message and the original PIKCHR input text (inside of <pre>...</pre>).
**
** The subroutine implemented by this file is intended to be stand-alone.
** It uses no external routines other than routines commonly found in
** the standard C library.
**
****************************************************************************
** COMPILING:
**
** The original source text is a mixture of C99 and "Lemon"
** (See https://sqlite.org/src/file/doc/lemon.html). Lemon is an LALR(1)
** parser generator program, similar to Yacc. The grammar of the
** input language is specified in Lemon. C-code is attached. Lemon
** runs to generate a single output file ("pikchr.c") which is then
** compiled to generate the Pikchr library. This header comment is
** preserved in the Lemon output, so you might be reading this in either
** the generated "pikchr.c" file that is output by Lemon, or in the
** "pikchr.y" source file that is input into Lemon. If you make changes,
** you should change the input source file "pikchr.y", not the
** Lemon-generated output file.
**
** Basic compilation steps:
**
** lemon pikchr.y
** cc pikchr.c -o pikchr.o
**
** Add -DPIKCHR_SHELL to add a main() routine that reads input files
** and sends them through Pikchr, for testing. Add -DPIKCHR_FUZZ for
** -fsanitizer=fuzzer testing.
**
****************************************************************************
** IMPLEMENTATION NOTES (for people who want to understand the internal
** operation of this software, perhaps to extend the code or to fix bugs):
**
** Each call to pikchr() uses a single instance of the Pik structure to
** track its internal state. The Pik structure lives for the duration
** of the pikchr() call.
**
** The input is a sequence of objects or "statements". Each statement is
** parsed into a PObj object. These are stored on an extensible array
** called PList. All parameters to each PObj are computed as the
** object is parsed. (Hence, the parameters to a PObj may only refer
** to prior statements.) Once the PObj is completely assembled, it is
** added to the end of a PList and never changes thereafter - except,
** PObj objects that are part of a "[...]" block might have their
** absolute position shifted when the outer [...] block is positioned.
** But apart from this repositioning, PObj objects are unchanged once
** they are added to the list. The order of statements on a PList does
** not change.
**
** After all input has been parsed, the top-level PList is walked to
** generate output. Sub-lists resulting from [...] blocks are scanned
** as they are encountered. All input must be collected and parsed ahead
** of output generation because the size and position of statements must be
** known in order to compute a bounding box on the output.
**
** Each PObj is on a "layer". (The common case is that all PObj's are
** on a single layer, but multiple layers are possible.) A separate pass
** is made through the list for each layer.
**
** After all output is generated, the Pik object and all the PList
** and PObj objects are deallocated and the generated output string is
** returned. Upon any error, the Pik.nErr flag is set, processing quickly
** stops, and the stack unwinds. No attempt is made to continue reading
** input after an error.
**
** Most statements begin with a class name like "box" or "arrow" or "move".
** There is a class named "text" which is used for statements that begin
** with a string literal. You can also specify the "text" class.
** A Sublist ("[...]") is a single object that contains a pointer to
** its substatements, all gathered onto a separate PList object.
**
** Variables go into PVar objects that form a linked list.
**
** Each PObj has zero or one names. Input constructs that attempt
** to assign a new name from an older name, for example:
**
** Abc: Abc + (0.5cm, 0)
**
** Statements like these generate a new "noop" object at the specified
** place and with the given name. As place-names are searched by scanning
** the list in reverse order, this has the effect of overriding the "Abc"
** name when referenced by subsequent objects.

/* The next sections is a series of control #defines.
** various aspects of the generated parser.
** YYCODETYPE is the data type used to store the integer codes
** that represent terminal and non-terminal symbols.
** "unsigned char" is used if there are fewer than
** 256 symbols. Larger types otherwise.
** YYNOCODE is a number of type YYCODETYPE that is not used for
** any terminal or nonterminal symbol.
** YYFALLBACK If defined, this indicates that one or more tokens
** (also known as: "terminal symbols") have fall-back
** values which should be used if the original symbol
** would not parse. This permits keywords to sometimes
** be used as identifiers, for example.
** YYACTIONTYPE is the data type used for "action codes" - numbers
** that indicate what to do in response to the next
** token.
** pik_parserTOKENTYPE is the data type used for minor type for terminal
** symbols. Background: A "minor type" is a semantic
** value associated with a terminal or non-terminal
** symbols. For example, for an "ID" terminal symbol,
** the minor type might be the name of the identifier.
** Each non-terminal can have a different minor type.
** Terminal symbols all have the same minor type, though.
** This macros defines the minor type for terminal
** symbols.
** YYMINORTYPE is the data type used for all minor types.
** This is typically a union of many types, one of
** which is pik_parserTOKENTYPE. The entry in the union
** for terminal symbols is called "yy0".
** YYSTACKDEPTH is the maximum depth of the parser's stack. If
** zero the stack is dynamically sized using realloc()
** pik_parserARG_SDECL A static variable declaration for the %extra_argument
** pik_parserARG_PDECL A parameter declaration for the %extra_argument
** pik_parserARG_PARAM Code to pass %extra_argument as a subroutine parameter
** pik_parserARG_STORE Code to store %extra_argument into yypParser
** pik_parserARG_FETCH Code to extract %extra_argument from yypParser
** pik_parserCTX_* As pik_parserARG_ except for %extra_context
** YYREALLOC Name of the realloc() function to use
** YYFREE Name of the free() function to use
** YYDYNSTACK True if stack space should be extended on heap
** YYERRORSYMBOL is the code number of the error symbol. If not
** defined, then do no error processing.
** YYNSTATE the combined number of states.
** YYNRULE the number of rules in the grammar
** YYNTOKEN Number of terminal symbols
** YY_MAX_SHIFT Maximum value for shift actions
** YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
** YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions
** YY_ERROR_ACTION The yy_action[] code for syntax error
** YY_ACCEPT_ACTION The yy_action[] code for accept
** YY_NO_ACTION The yy_action[] code for no-op
** YY_MIN_REDUCE Minimum value for reduce actions
** YY_MAX_REDUCE Maximum value for reduce actions
** YY_MIN_DSTRCTR Minimum symbol value that has a destructor
** YY_MAX_DSTRCTR Maximum symbol value that has a destructor

/* Next are the tables used to determine what action to take based on the
** current state and lookahead token. These tables are used to implement
** functions that take a state number and lookahead value and return an
** action integer.
**
** Suppose the action integer is N. Then the action is determined as
** follows
**
** 0 <= N <= YY_MAX_SHIFT Shift N. That is, push the lookahead
** token onto the stack and goto state N.
**
** N between YY_MIN_SHIFTREDUCE Shift to an arbitrary state then
** and YY_MAX_SHIFTREDUCE reduce by rule N-YY_MIN_SHIFTREDUCE.
**
** N == YY_ERROR_ACTION A syntax error has occurred.
**
** N == YY_ACCEPT_ACTION The parser accepts its input.
**
** N == YY_NO_ACTION No such action. Denotes unused
** slots in the yy_action[] table.
**
** N between YY_MIN_REDUCE Reduce by rule N-YY_MIN_REDUCE
** and YY_MAX_REDUCE
**
** The action table is constructed as a single large table named yy_action[].
** Given state S and lookahead X, the action is computed as either:
**
** (A) N = yy_action[ yy_shift_ofst[S] + X ]
** (B) N = yy_default[S]
**
** The (A) formula is preferred. The B formula is used instead if
** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X.
**
** The formulas above are for computing the action when the lookahead is
** a terminal symbol. If the lookahead is a non-terminal (as occurs after
** a reduce action) then the yy_reduce_ofst[] array is used in place of
** the yy_shift_ofst[] array.
**
** The following are the tables generated in this section:
**
** yy_action[] A single table containing all actions.
** yy_lookahead[] A table containing the lookahead for each entry in
** yy_action. Used to detect hash collisions.
** yy_shift_ofst[] For each state, the offset into yy_action for
** shifting terminals.
** yy_reduce_ofst[] For each state, the offset into yy_action for
** shifting non-terminals after a reduce.
** yy_default[] Default action for each state.

Type "fossil ui" and Fossil automatically opens a web browser to a page that shows detailed graphical history and status information on that project. .HP 3. .B Self-Contained - Fossil is a single self-contained stand-alone executable. To install, simply download a precompiled binary for Linux, Mac, OpenBSD, or Windows and put it on your $PATH. Easy-to-compile source code is available for users on other platforms. .HP 4. .B Simple Networking - No custom protocols or TCP ports. Fossil uses plain old HTTP (or HTTPS or SSH) for all network communications, so it works fine from behind restrictive firewalls, including proxies. The protocol is bandwidth efficient to the point that Fossil can be used comfortably over dial-up or over the exceedingly slow Wifi on airliners. .HP 5. .B CGI/SCGI Enabled - No server is required, but if you want to set one up, Fossil supports four easy server configurations. .HP 6. .B Autosync - Fossil supports "autosync" mode which helps to keep projects moving forward by reducing the amount of needless forking and merging often associated with distributed projects. .HP 7. .B Robust & Reliable - Fossil stores content using an enduring file format in an SQLite database so that transactions are atomic even if interrupted by a power loss or system crash. Automatic self-checks verify that all aspects of the repository are consistent prior to each commit. .HP 8. .B Free and Open-Source - Uses the 2-clause BSD license. .SH DOCUMENTATION https://fossil-scm.org/ .br .B fossil \fIui\fR |

Built-in Skins
==============
Each subdirectory under this folder describes a built-in "skin".
There are five key files in each subdirectory:
* `css.txt` → The CSS for the skin
* `details.txt` → Skin-specific settings
* `footer.txt` → Text of the Content Footer for each page
* `header.txt` → Text of the Content Header for each page
* `js.txt` → Javascript included in the Content Footer
To improve an existing built-in skin, simply edit the appropriate
files and recompile.
To add a new skin:
1. Create a new subdirectory under skins/. (The new directory is
called "skins/newskin" below but you should use a new original
name, of course.)
2. Add files skins/newskin/css.txt, skins/newskin/details.txt,
skins/newskin/footer.txt, skins/newskin/header.txt, and
skins/newskin/js.txt. Be sure to "fossil add" these files.
3. Go to the tools/ directory and rerun "tclsh makemake.tcl". This
step rebuilds the various makefiles so that they have dependencies
on the skin files you just installed.
4. Edit the BuiltinSkin[] array near the top of the src/skins.c source
file so that it describes and references the "newskin" skin.
5. Type "make" to rebuild.
See the [custom skin documentation](/doc/$CURRENT/www/customskin.md) for
more information.
Development Hints
-----------------
One way to develop a new skin is to copy the baseline files (css.txt,
details.txt, footer.txt, header.txt, and js.txt) into a working
directory $WORKDIR then launch Fossil with a command-line option
"--skin $WORKDIR". Example:
cp -r skins/default newskin
fossil ui --skin ./newskin
When the argument to --skin contains one or more '/' characters, the
appropriate skin files are read from disk from the directory specified.
So after launching fossil as shown above, you can edit the newskin/*.txt
files using your favorite text editor, then press Reload on your browser
to see immediate results.

## Ardoise theme
A black and grey skin ("Ardoise" is the french word for slate).
The skin includes custom icons for the file browser and the WYSIWYG editor, which are embedded directly in the css as base64 blobs. For convenience, they are also provided as standalone files in the images subdirectory.
This skin was contributed by Antoine Chavasse.
This theme is loosely based upon, and still contains some elements from the Blitz theme by James Moger.
This theme embeds & uses a modified copy of [Normalize 3.0.2](https://necolas.github.io/normalize.css/) which is distributed under an [MIT license](https://github.com/necolas/normalize.css/blob/master/LICENSE.md).
This theme embeds & uses a modified copy of [Skeleton](http://getskeleton.com) which is distributed under an [MIT license](https://github.com/dhg/Skeleton/blob/master/LICENSE.md).

This theme embeds & uses an unmodified copy of [Normalize 3.0.2](https://necolas.github.io/normalize.css/) which is distributed under an [MIT license](https://github.com/necolas/normalize.css/blob/master/LICENSE.md). This theme uses half of a heavily-modified version of [Skeleton](http://getskeleton.com) which is distributed under an [MIT license](https://github.com/dhg/Skeleton/blob/master/LICENSE.md). None of the responsive elements (media queries) are included at this time. The font used in the included Fossil logo image is [Trillium Web Light](http://www.google.com/fonts/specimen/Titillium+Web) @ 48px HTML color code #456a7a. The RSS feed icon is sourced from [Font-Awesome](https://fortawesome.github.io/Font-Awesome/icons) by Dave Gandy and is distributed under the [SIL OFL 1.1 ](http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=OFL) license. |

Added skins/default/README.md.
> > > > > > > > > > | 1 2 3 4 5 6 7 8 9 10 | This skin was originally contributed by Étienne Deparis on 2015-02-22, promoted to the default on 2015-03-14, and subsequently changed by many: https://fossil-scm.org/home/finfo/skins/default/css.txt https://fossil-scm.org/home/blame?filename=skins/default/css.txt&checkin=trunk In February 2024, a sufficiently large set of changes were made to the skin that we forked the old version for the benefit of those who needed to reference the old one — as when migrating custom skin changes to work atop the new default — or who simply preferred it. See ../etienne. |

/* Mark inline code fragments in the near-universal manner pioneered by
* Stack Overflow, then picked up by approximately everyone, including
* us, now.
*
* This combinatorial selector explosion results from a need to apply
* these stylings inside multiple page container types, multiplied by
* the surprisingly large number of tags HTML defines for semantically
* differentiated monospaced inline markup. If we do not target the
* elements we want to affect carefully, we'll end up overreaching,
* styling Fossil UI elements that use these tags for local purposes.
*
* HTML generated and emitted by Fossil UI does not always fall under
* the skin's generic rules; we must avoid intruding on its domain.
* Our limited intent here is to style user content only, where it is
* unreasonable to expect its author to take the time to hand-craft
* per-document styling. Contrast Fossil UI, which often does exactly
* that in order to get particular results.
*
* Its rough equivalent in Sass syntax is far more compact, thus clearer:
*
* .artifact, .dir, .doc, .forum, .wiki // the page types we target
* > .content // hands off header & footer
* &, > .fossil-doc, > .markdown // wiki, HTML & MD emb docs
* > p // in top-level paras only
* > code, > kbd, > samp, > tt, > var // monospaced tag types
* background-color: #f4f4f4 // pale gray box which…
* padding: 0 4px // …extends around the sides
*
* We then need something similar for the block-level pre elements.
*
* The CSS below is based on feeding that Sass code through this:
*
* $ sassc code.sass | sed -e 's/, /,\n/g'
*
* …then hand-cleansing it to make it _somewhat_ more understandable.
* That largely amounts to whitespace tweaks, but we've also done things
* like trim back the forum-specific styling to apply to the default MD
* markup only; direct HTML formatting isn't even an option there, and
* while wiki markup _is_ supported, MD was the default from day 1.
* Another quirk of the forum post handling is that the .markdown class
* gets applied per-post, not up at the top level as with the wiki,
* embedded docs, etc.

## NOTE: The purpose of this procedure is to take the base URL of the
## Fossil project and return the root of the entire web site using

## NOTE: (part 1) The [string first] command does NOT actually
## support the optional startIndex argument as specified
## in the TH1 support manual; therefore, we fake it by
## using the [string range] command and then adding the
## necessary offset to the resulting index manually
## (below). In Tcl, we could use the following instead:
##
## set idx(next) [string first / $baseurl $idx(first+1)]
##
set idx(nextRange) [string range $baseurl $idx(first+1) end]
set idx(next) [string first / $idx(nextRange)]

## NOTE: (part 2) Add the necessary offset to the result of
## the search for the next slash (i.e. the one after
## the initial search for the two slashes).
##
set idx(next) [expr {$idx(next) + $idx(first+1)}]

Added skins/etienne/README.md.
> > > > > > > > > > > > > > | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | This skin was contributed by Étienne Deparis. It was promoted to the default from 2015-03-14 until February 2024, when it was forked into this location for use by those who do not want the large number of changes merged into trunk at that time. Even if you agree with us that the changes improve readability, you may prefer to pack more information onto the screen at the expense of readability. Other reasons to choose this fork are to migrate custom skin changes to work atop the new base, or to make a comparative design evaluation. A bare minimum of changes have been made to this fork, primarily to allow this skin to render the Fossil documentation in a readable fashion. The intent is that you be able to toggle between these two skins at will. |

## NOTE: The purpose of this procedure is to take the base URL of the
## Fossil project and return the root of the entire web site using

## NOTE: (part 1) The [string first] command does NOT actually
## support the optional startIndex argument as specified
## in the TH1 support manual; therefore, we fake it by
## using the [string range] command and then adding the
## necessary offset to the resulting index manually
## (below). In Tcl, we could use the following instead:
##
## set idx(next) [string first / $baseurl $idx(first+1)]
##
set idx(nextRange) [string range $baseurl $idx(first+1) end]
set idx(next) [string first / $idx(nextRange)]
if {$idx(next) != -1} {
##
## NOTE: (part 2) Add the necessary offset to the result of
## the search for the next slash (i.e. the one after
## the initial search for the two slashes).
##
set idx(next) [expr {$idx(next) + $idx(first+1)}]

## NOTE: Back up one character from the next slash.

/*
** Attach appropriate javascript to each ".accordion" button so that it expands
** and contracts when clicked.
**
** The uncompressed source code for the SVG icons can be found on the wiki page
** "branch/accordion-experiments" in the Fossil repository.
**
** Implementation notes:
**
** The `maxHeight' CSS property is quite restrictive for vertical resizing of
** elements, especially for dynamic-content areas like the diff panels. That's
** why `maxHeight' is set only during animation, to prevent truncated elements.
** (The diff panels may get truncated right after page loading, and other
** elements may get truncated when resizing the browser window to a smaller
** width, causing vertical growth.)
**
** Another problem is that `scrollHeight' used to calculate the expanded height
** while still in the contracted state may return values with small errors on
** some browsers, especially for large elements, presumably due to omitting the
** space required by the vertical scrollbar that may become necessary, causing
** additional horizontal shrinking and consequently more vertical growth than
** calculated. That's why setting `maxHeight' to `scrollHeight' is considered
** "good enough" only during animation, but cleared afterwards.

** COMMAND: add
**
** Usage: %fossil add ?OPTIONS? FILE1 ?FILE2 ...?
**
** Make arrangements to add one or more files or directories to the
** current check-out at the next [[commit]].
**
** When adding files or directories recursively, filenames that begin
** with "." are excluded by default. To include such files, add
** the "--dotfiles" option to the command-line.
**
** The --ignore and --clean options are comma-separated lists of glob patterns
** for files to be excluded. Example: '*.o,*.obj,*.exe' If the --ignore
** option does not appear on the command line then the "ignore-glob" setting
** is used. If the --clean option does not appear on the command line then
** the "clean-glob" setting is used.
**
** If files are attempted to be added explicitly on the command line which
** match "ignore-glob", a confirmation is asked first. This can be prevented
** using the -f|--force option.
**
** The --case-sensitive option determines whether or not filenames should
** be treated case sensitive or not. If the option is not given, the default
** depends on the global setting, or the operating system default, if not set.
**
** Options:
** --case-sensitive BOOL Override the case-sensitive setting
** --dotfiles Include files beginning with a dot (".")
** -f|--force Add files without prompting
** --ignore CSG Ignore unmanaged files matching patterns from
** the Comma Separated Glob (CSG) pattern list
** --clean CSG Also ignore files matching patterns from
** the Comma Separated Glob (CSG) list
** --reset Reset the ADDED state of a check-out, such
** that all newly-added (but not yet committed)
** files are no longer added. No flags other
** than --verbose and --dry-run may be used
** with --reset.
** --allow-reserved Permit filenames which are reserved on
** Windows platforms. Such files cannot be
** checked out on Windows, so use with care.

** Usage: %fossil mv|rename OLDNAME NEWNAME
** or: %fossil mv|rename OLDNAME... DIR
**
** Move or rename one or more files or directories within the repository tree.
** You can either rename a file or directory or move it to another subdirectory.
**
** The 'mv' command does NOT normally rename or move the files on disk.
** This command merely records the fact that file names have changed so
** that appropriate notations can be made at the next [[commit]].
** However, the default behavior of this command may be overridden via
** command line options listed below and/or the 'mv-rm-files' setting.
**
** The 'rename' command never renames or moves files on disk, even when the
** command line options and/or the 'mv-rm-files' setting would otherwise
** require it to do so.
**
** WARNING: If the "--hard" option is specified -OR- the "mv-rm-files"
** setting is non-zero, files WILL BE renamed or moved on disk
** as well. This does NOT apply to the 'rename' command.
**
** Options:
** --soft Skip moving files within the check-out.
** This supersedes the --hard option.
** --hard Move files within the check-out
** --case-sensitive BOOL Override the case-sensitive setting
** -n|--dry-run If given, display instead of run actions
**
** See also: [[changes]], [[status]]

**
** * The user is logged into an account other than "nobody" or
** "anonymous". In that case the notification settings
** associated with that account can be edited without needing
** to know the subscriber code.

** in length.) This uniquely identifies the subscriber without
** revealing the complete subscriber code, and hence without

**
** (3) Loop over all subscribers. Compose and send one or more email
** messages to each subscriber that describe the events for
** which the subscriber has expressed interest and has
** appropriate privileges.
**
** (4) Update the pending_alerts table to indicate that alerts have been
** sent.
**
** Update 2018-08-09: Do step (3) before step (4). Update the
** pending_alerts table *before* the emails are sent. That way, if

/*
** COMMAND: all
**
** Usage: %fossil all SUBCOMMAND ...
**
** The ~/.fossil file records the location of all repositories for a
** user. This command performs certain operations on all repositories
** that can be useful before or after a period of disconnected operation.
**
** On Win32 systems, the file is named "_fossil" and is located in
** %LOCALAPPDATA%, %APPDATA% or %HOMEPATH%.
**
** Available operations are:
**
** backup Backup all repositories. The argument must be the name of
** a directory into which all backup repositories are written.
**
** cache Manages the cache used for potentially expensive web
** pages. Any additional arguments are passed on verbatim
** to the cache command.
**
** changes Shows all local check-outs that have uncommitted changes.
** This operation has no additional options.
**
** clean Delete all "extra" files in all local check-outs. Extreme
** caution should be exercised with this command because its
** effects cannot be undone. Use of the --dry-run option to
** carefully review the local check-outs to be operated upon
** and the --whatif option to carefully review the files to
** be deleted beforehand is highly recommended. The command
** line options supported by the clean command itself, if any
** are present, are passed along verbatim.
**
** config Only the "config pull AREA" command works.
**
** dbstat Run the "dbstat" command on all repositories.
**
** extras Shows "extra" files from all local check-outs. The command
** line options supported by the extra command itself, if any
** are present, are passed along verbatim.
**
** fts-config Run the "fts-config" command on all repositories.
**
** git CMD Do the "git export" or "git status" command (whichever
** is specified by CMD) on all repositories for which
** a Git mirror has been previously established.
**
** info Run the "info" command on all repositories.
**
** pull Run a "pull" operation on all repositories. Only the
** --verbose and --share-links options are supported.
**
** push Run a "push" on all repositories. Only the --verbose
** option is supported.
**
** rebuild Rebuild on all repositories. The command line options
** supported by the rebuild command itself, if any are
** present, are passed along verbatim. The --force option
** is not supported.
**
** remote Show remote hosts for all repositories.
**
** repack Look for extra compression in all repositories.
**
** sync Run a "sync" on all repositories. Only the --verbose
** and --unversioned and --share-links options are supported.
**
** set[tings] Run the "settings" command on all repositories.
** This command is useful for settings like "max-loadavg" which
** you usually want to be the same across all repositories
** on a server.
**
** unset Run the "unset" command on all repositories
**
** server Run the "server" commands on all repositories.
** The root URI gives a listing of all repos.
**
** ui Run the "ui" command on all repositories. Like "server"
** but bind to the loopback TCP address only, enable
** the --localauth option and automatically launch a
** web-browser
**
** whatis Run the "whatis" command on all repositories. Only
** show output for repositories that have a match.
**
**
** In addition, the following maintenance operations are supported:
**
** add Add all the repositories named to the set of repositories
** tracked by Fossil. Normally Fossil is able to keep up with
** this list by itself, but sometimes it can benefit from this
** hint if you rename repositories.
**
** ignore Arguments are repositories that should be ignored by
** subsequent clean, extras, list, pull, push, rebuild, and
** sync operations. The -c|--ckout option causes the listed
** local check-outs to be ignored instead.
**
** list | ls Display the location of all repositories. The -c|--ckout
** option causes all local check-outs to be listed instead.
**
** Repositories are automatically added to the set of known repositories
** when one of the following commands are run against the repository:
** clone, info, pull, push, or sync. Even previously ignored repositories
** are added back to the list of repositories by these commands.
**
** Options:
** --dry-run If given, display instead of run actions
** --showfile Show the repository or check-out being operated upon
** --stop-on-error Halt immediately if any subprocess fails

*******************************************************************************
**
** This file contains code used to manage a background processes that
** occur after user interaction with the repository. Examples of
** backoffice processing includes:
**
** * Sending alerts and notifications
** * Processing the email queue
** * Handling post-receive hooks
** * Automatically syncing to peer repositories
**
** Backoffice processing is automatically started whenever there are
** changes to the repository. The backoffice process dies off after
** a period of inactivity.
**
** Steps are taken to ensure that only a single backoffice process is
** running at a time. Otherwise, there could be race conditions that
** cause adverse effects such as multiple alerts for the same changes.
**
** At the same time, we do not want a backoffice process to run forever.
** Backoffice processes should die off after doing whatever work they need
** to do. In this way, we avoid having lots of idle processes in the
** process table, doing nothing on rarely accessed repositories, and
** if the Fossil binary is updated on a system, the backoffice processes
** will restart using the new binary automatically.
**
** At any point in time there should be at most two backoffice processes.
** There is a main process that is doing the actually work, and there is
** a second stand-by process that is waiting for the main process to finish
** and that will become the main process after a delay.
**
** After any successful web page reply, the backoffice_check_if_needed()
** routine is called. That routine checks to see if both one or both of
** the backoffice processes are already running. That routine remembers the
** status in a global variable.
**
** Later, after the repository database is closed, the
** backoffice_run_if_needed() routine is called. If the prior call
** to backoffice_check_if_needed() indicated that backoffice processing
** might be required, the run_if_needed() attempts to kick off a backoffice
** process.
**
** All work performance by the backoffice is in the backoffice_work()
** routine.

/*
** COMMAND: backoffice*
**
** Usage: %fossil backoffice [OPTIONS...] [REPOSITORIES...]
**
** Run backoffice processing on the repositories listed. If no
** repository is specified, run it on the repository of the local check-out.
**
** This might be done by a cron job or similar to make sure backoffice
** processing happens periodically. Or, the --poll option can be used
** to run this command as a daemon that will periodically invoke backoffice
** on a collection of repositories.
**
** If only a single repository is named and --poll is omitted, then the
** backoffice work is done in-process. But if there are multiple repositories
** or if --poll is used, a separate sub-process is started for each poll of
** each repository.
**
** Standard options:
**
** --debug Show what this command is doing
**
** --logfile FILE Append a log of backoffice actions onto FILE
**
** --min N When polling, invoke backoffice at least
** once every N seconds even if the repository
** never changes. 0 or negative means disable
** this feature. Default: 3600 (once per hour).
**
** --poll N Repeat backoffice calls for repositories that
** change in appoximately N-second intervals.
** N less than 1 turns polling off (the default).
** Recommended polling interval: 60 seconds.
**
** --trace Enable debugging output on stderr
**
** Options intended for internal use only which may change or be
** discontinued in future releases:
**
** --nodelay Do not queue up or wait for a backoffice job
** to complete. If no work is available or if
** backoffice has run recently, return immediately.
**
** --nolease Always run backoffice, even if there is a lease
** conflict. This option implies --nodelay. This
** option is added to secondary backoffice commands
** that are invoked by the --poll option.

/*
** COMMAND: bisect
**
** Usage: %fossil bisect SUBCOMMAND ...
**
** Run various subcommands useful for searching back through the change
** history for a particular check-in that causes or fixes a problem.
**
** > fossil bisect bad ?VERSION?
**
** Identify version VERSION as non-working. If VERSION is omitted,
** the current check-out is marked as non-working.
**
** > fossil bisect good ?VERSION?
**
** Identify version VERSION as working. If VERSION is omitted,
** the current check-out is marked as working.
**
** > fossil bisect log
** > fossil bisect chart
**
** Show a log of "good", "bad", and "skip" versions. "bisect log"
** shows the events in the order that they were tested.
** "bisect chart" shows them in order of check-in.
**
** > fossil bisect next
**
** Update to the next version that is halfway between the working and
** non-working versions.
**
** > fossil bisect options ?NAME? ?VALUE?
**
** List all bisect options, or the value of a single option, or set the
** value of a bisect option.
**
** > fossil bisect reset
**
** Reinitialize a bisect session. This cancels prior bisect history
** and allows a bisect session to start over from the beginning.
**
** > fossil bisect run [OPTIONS] COMMAND
**
** Invoke COMMAND repeatedly to run the bisect. The exit code for
** COMMAND should be 0 for "good", 125 for "skip", and any other value
** for "bad".
**
** Options:
** -i|--interactive Prompt the user for the good/bad/skip decision
** after each step, rather than using the exit
** code from COMMAND
**
** > fossil bisect skip ?VERSION?
**
** Cause VERSION (or the current check-out if VERSION is omitted) to
** be ignored for the purpose of the current bisect. This might
** be done, for example, because VERSION does not compile correctly
** or is otherwise unsuitable to participate in this bisect.
**
** > fossil bisect vlist|ls|status ?-a|--all?
**
** List the versions in between the inner-most "bad" and "good".
**
** > fossil bisect ui
**
** Like "fossil ui" except start on a timeline that shows only the
** check-ins that are part of the current bisect.
**
** > fossil bisect undo
**
** Undo the most recent "good", "bad", or "skip" command.

** COMMAND: test-escaped-arg
**
** Usage %fossil ARGS ...
**
** Run each argument through blob_append_escaped_arg() and show the
** result. Append each argument to "fossil test-echo" and run that
** using fossil_system() to verify that it really does get escaped
** correctly.
**
** Other options:
**
** --filename-args BOOL Subsequent arguments are assumed to be
** filenames if BOOL is true, or not if BOOL
** is false. Defaults on.
**
** --hex HEX Skip the --hex flag and instead decode HEX
** into ascii. This provides a way to insert
** unusual characters as an argument for testing.
**
** --compare HEX ASCII Verify that argument ASCII is identical to
** to decoded HEX.
**
** --fuzz N Run N fuzz cases. Each cases is a call
** to "fossil test-escaped-arg --compare HEX ARG"
** where HEX and ARG are the same argument.
** The argument is chosen at random.

**
** Create a new branch BRANCH-NAME off of check-in BASIS.
**
** Options:
** --private Branch is private (i.e., remains local)
** --bgcolor COLOR Use COLOR instead of automatic background
** --nosign Do not sign the manifest for the check-in
** that creates this branch
** --nosync Do not auto-sync prior to creating the branch
** --date-override DATE DATE to use instead of 'now'
** --user-override USER USER to use instead of the current default
**
** DATE may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in
** year-month-day form, it may be truncated, the "T" may be
** replaced by a space, and it may also name a timezone offset
** from UTC as "-HH:MM" (westward) or "+HH:MM" (eastward).
** Either no timezone suffix or "Z" means UTC.

** Options:
** -R|--repository REPO Run commands on repository REPO

** Convenience wrapper which calls builtin_request_js() for a series

** initialize the window.fossil JS API. The first argument is the NAME
** part of the first API to emit. All subsequent arguments must be
** strings of the NAME part of additional fossil.NAME.js files,
** followed by a NULL argument to terminate the list.
**
** e.g. pass it ("fetch", "dom", "tabs", NULL) to load those 3 APIs (or
** pass it ("fetch","tabs",NULL), as "dom" is a dependency of "tabs", so
** it will be automatically loaded). Do not forget the trailing NULL,
** and do not pass 0 instead, since that isn't always equivalent to NULL
** in this context.
**
** If it is JS_BUNDLED then this routine queues up an emit of ALL of
** the JS fossil.XYZ.js APIs which are not strictly specific to a
** single page, and then calls builtin_fulfill_js_requests(). The idea
** is that we can get better bundle caching and reduced HTTP requests
** by including all JS, rather than creating separate bundles on a
** per-page basis. In this case, all arguments are ignored!
**
** This function has an internal mapping of the dependencies for each
** of the known fossil.XYZ.js modules and ensures that the
** dependencies also get queued (recursively) and that each module is
** queued only once.
**
** If passed a name which is not a base fossil module name then it
** will fail fatally!
**
** DO NOT use this for loading fossil.page.*.js: use
** builtin_request_js() for those.
**
** If the current JS delivery mode is *not* JS_BUNDLED then this
** function queues up a request for each given module and its known
** dependencies, but does not immediately fulfill the request, thus it
** can be called multiple times.
**
** If a given module is ever passed to this more than once, either in
** a single invocation or multiples, it is only queued for emit a
** single time (i.e. the 2nd and subsequent ones become
** no-ops). Likewise, if a module is requested but was already
** automatically queued to fulfill a dependency, the explicit request
** becomes a no-op.
**
** Bundled mode is the only mode in which this API greatly improves
** aggregate over-the-wire and HTTP request costs. For other modes,
** reducing the inclusion of fossil.XYZ APIs to their bare minimum
** provides the lowest aggregate costs. For debate and details, see
** the discussion at:
**
** https://fossil-scm.org/forum/forumpost/3fa2633f3e
**
** In practice it is normally necessary (or preferred) to call
** builtin_fulfill_js_requests() after calling this, before proceeding
** to call builtin_request_js() for page-specific JS, in order to
** improve cachability.
**
** Minor caveat: the purpose of emitting all of the fossil.XYZ JS APIs
** at once is to reduce over-the-wire transfers by enabling cross-page
** caching, but if there are other JS scripts pending via
** builtin_request_js() when this is called then they will be included
** in the JS request emitted by this routine, resulting in a different
** script URL than if they were not included. Thus, if a given page
** has its own scripts to install via builtin_request_js(), they
** should, if possible, be delayed until after this is called OR the
** page should call builtin_fulfill_js_requests() to flush the request
** queue before calling this routine.
**
** Achtung: the fossil.page.XYZ.js files are page-specific, containing
** the app-level logic for that specific page, and loading more than
** one of them in a single page will break that page. Each of those
** expects to "own" the page it is loaded in, and it should be loaded
** as late in the JS-loading process as feasible, ideally bundled (via
** builtin_request_js()) with any other app-/page-specific JS it may
** need.
**
** Example usage:
**
** builtin_fossil_js_bundle_or("dom", "fetch", NULL);
**
** In bundled mode, that will (the first time it is called) emit all
** builtin fossil JS APIs and "fulfill" the queue immediately. In
** non-bundled mode it will queue up the "dom" and "fetch" APIs to be
** emitted the next time builtin_fulfill_js_requests() is called.

*******************************************************************************
**
** This file began as a set of C functions and procedures used intepret
** CGI environment variables for Fossil web pages that were invoked by
** CGI. That's where the file name comes from. But over the years it
** has grown to incorporate lots of related functionality, including:
**
** * Interpreting CGI environment variables when Fossil is run as
** CGI (the original purpose).
**
** * Interpreting HTTP requests received directly or via an SSH tunnel.
**
** * Interpreting SCGI requests
**
** * Generating appropriate replies to CGI, SCGI, and HTTP requests.
**
** * Listening for incoming HTTP requests and dispatching them.
** (Used by "fossil ui" and "fossil server", for example).
**
** So, even though the name of this file implies that it only deals with
** CGI, in fact, the code in this file is used to interpret webpage requests
** received by a variety of means, and to generate well-formatted replies
** to those requests.
**
** The code in this file abstracts the web-request so that downstream
** modules that generate the body of the reply (based on the requested page)
** do not need to know if the request is coming from CGI, direct HTTP,
** SCGI, or some other means.
**
** This module gathers information about web page request into a key/value
** store. Keys and values come from:
**
** * Query parameters
** * POST parameter
** * Cookies
** * Environment variables
**
** The parameters are accessed using cgi_parameter() and similar functions
** or their convenience macros P() and similar.
**
** Environment variable parameters are set as if the request were coming
** in over CGI even if the request arrived via SCGI or direct HTTP. Thus
** the downstream modules that are trying to interpret the request do not
** need to know the request protocol - they can just request the values
** of environment variables and everything will always work.
**
** This file contains routines used by Fossil when it is acting as a
** CGI client. For the code used by Fossil when it is acting as a
** CGI server (for the /ext webpage) see the "extcgi.c" source file.

**
** This file contains code used to implement the Fossil chatroom.
**
** Initial design goals:
**
** * Keep it simple. This chatroom is not intended as a competitor
** or replacement for IRC, Discord, Telegram, Slack, etc. The goal
** is zero- or near-zero-configuration, not an abundance of features.
**
** * Intended as a place for insiders to have ephemeral conversations
** about a project. This is not a public gather place. Think
** "boardroom", not "corner pub".
**
** * One chatroom per repository.
**
** * Chat content lives in a single repository. It is never synced.
** Content expires and is deleted after a set interval (a week or so).
**
** Notification is accomplished using the "hanging GET" or "long poll" design
** in which a GET request is issued but the server does not send a reply until
** new content arrives. Newer Web Sockets and Server Sent Event protocols are
** more elegant, but are not compatible with CGI, and would thus complicate
** configuration.

/* Settings that can be used to control chat */
/*
** SETTING: chat-initial-history width=10 default=50
**
** If this setting has an integer value of N, then when /chat first
** starts up it initializes the screen with the N most recent chat
** messages. If N is zero, then all chat messages are loaded.
*/
/*
** SETTING: chat-keep-count width=10 default=50
**
** When /chat is cleaning up older messages, it will always keep
** the most recent chat-keep-count messages, even if some of those
** messages are older than the discard threshold. If this value
** is zero, then /chat is free to delete all historic messages once
** they are old enough.
*/
/*
** SETTING: chat-keep-days width=10 default=7
**
** The /chat subsystem will try to discard messages that are older then
** chat-keep-days. The value of chat-keep-days can be a floating point
** number. So, for example, if you only want to keep chat messages for
** 12 hours, set this value to 0.5.
**
** A value of 0.0 or less means that messages are retained forever.
*/
/*
** SETTING: chat-inline-images boolean default=on
**
** Specifies whether posted images in /chat should default to being
** displayed inline or as downloadable links. Each chat user can
** change this value for their current chat session in the UI.
*/
/*
** SETTING: chat-poll-timeout width=10 default=420
**
** On an HTTP request to /chat-poll, if there is no new content available,
** the reply is delayed waiting for new content to arrive. (This is the
** "long poll" strategy of event delivery to the client.) This setting
** determines approximately how long /chat-poll will delay before giving
** up and returning an empty reply. The default value is about 7 minutes,
** which works well for Fossil behind the althttpd web server. Other
** server environments may choose a longer or shorter delay.
**
** For maximum efficiency, it is best to choose the longest delay that
** does not cause timeouts in intermediate proxies or web server.

** WEBPAGE: chat-poll hidden loadavg-exempt
**
** The chat page generated by /chat using an XHR to this page to
** request new chat content. A typical invocation is:
**
** /chat-poll/N
** /chat-poll?name=N
**
** The "name" argument should begin with an integer which is the largest
** "msgid" that the chat page currently holds. If newer content is
** available, this routine returns that content straight away. If no new
** content is available, this webpage blocks until the new content becomes
** available. In this way, the system implements "hanging-GET" or "long-poll"
** style event notification. If no new content arrives after a delay of
** approximately chat-poll-timeout seconds (default: 420), then reply is
** sent with an empty "msg": field.
**
** If N is negative, then the return value is the N most recent messages.
** Hence a request like /chat-poll/-100 can be used to initialize a new
** chat session to just the most recent messages.
**
** Some webservers (althttpd) do not allow a term of the URL path to
** begin with "-". Then /chat-poll/-100 cannot be used. Instead you
** have to say "/chat-poll?name=-100".
**
** If the integer parameter "before" is passed in, it is assumed that
** the client is requesting older messages, up to (but not including)
** that message ID, in which case the next-oldest "n" messages
** (default=chat-initial-history setting, equivalent to n=0) are
** returned (negative n fetches all older entries). The client then
** needs to take care to inject them at the end of the history rather
** than the same place new messages go.
**
** If "before" is provided, "name" is ignored.
**
** If "raw" is provided, the "xmsg" text is sent back as-is, in
** markdown format, rather than being HTML-ized. This is not used or
** supported by fossil's own chat client but is intended for 3rd-party
** clients. (Specifically, for Brad Harder's curses-based client.)
**
** The reply from this webpage is JSON that describes the new content.
** Format of the json:
**
** | {
** | "msgs":[
** | {
** | "msgid": integer // message id
** | "mtime": text // When sent: YYYY-MM-DDTHH:MM:SSZ
** | "lmtime: text // Sender's client-side YYYY-MM-DDTHH:MM:SS
** | "xfrom": text // Login name of sender
** | "uclr": text // Color string associated with the user
** | "xmsg": text // HTML text of the message
** | "fsize": integer // file attachment size in bytes
** | "fname": text // Name of file attachment
** | "fmime": text // MIME-type of file attachment
** | "mdel": integer // message id of prior message to delete
** | }
** | ]
** | }
**
** The "fname" and "fmime" fields are only present if "fsize" is greater
** than zero. The "xmsg" field may be an empty string if "fsize" is zero.
**
** The "msgid" values will be in increasing order.
**
** The "mdel" will only exist if "xmsg" is an empty string and "fsize" is zero.
**
** The "lmtime" value might be unknown, in which case it is omitted.
**
** The messages are ordered oldest first unless "before" is provided, in which
** case they are sorted newest first (to facilitate the client-side UI update).
**
** As a special case, if this routine encounters an error, e.g. the user's
** permissions cannot be verified because their login cookie expired, the
** request returns a slightly modified structure:
**
** | {
** | "msgs":[
** | {
** | "isError": true,
** | "xfrom": null,
** | "xmsg": "error details"
** | "mtime": as above,
** | "ltime": same as mtime
** | }
** | ]
** | }
**
** If the client gets such a response, it should display the message
** in a prominent manner and then stop polling for new messages.

** COMMAND: chat
**
** Usage: %fossil chat [SUBCOMMAND] [--remote URL] [ARGS...]
**
** This command performs actions associated with the /chat instance
** on the default remote Fossil repository (the Fossil repository whose
** URL shows when you run the "fossil remote" command) or to the URL
** specified by the --remote option. If there is no default remote
** Fossil repository and the --remote option is omitted, then this
** command fails with an error.
**
** Subcommands:
**
** > fossil chat
**
** When there is no SUBCOMMAND (when this command is simply "fossil chat")
** the response is to bring up a web-browser window to the chatroom
** on the default system web-browser. You can accomplish the same by
** typing the appropriate URL into the web-browser yourself. This
** command is merely a convenience for command-line oriented people.
**
** > fossil chat pull
**
** Copy chat content from the server down into the local clone,
** as a backup or archive. Setup privilege is required on the server.
**
** --all Download all chat content. Normally only
** previously undownloaded content is retrieved.
** --debug Additional debugging output
** --out DATABASE Store CHAT table in separate database file
** DATABASE rather that adding to local clone
** --unsafe Allow the use of unencrypted http://
**
** > fossil chat send [ARGUMENTS]
**
** This command sends a new message to the chatroom. The message
** to be sent is determined by arguments as follows:
**
** -f|--file FILENAME File to attach to the message
** --as FILENAME2 Causes --file FILENAME to be sent with
** the attachment name FILENAME2
** -m|--message TEXT Text of the chat message
** --remote URL Send to this remote URL
** --unsafe Allow the use of unencrypted http://
**
** > fossil chat url
**
** Show the default URL used to access the chat server.

** COMMAND: changes
** COMMAND: status
**
** Usage: %fossil changes|status ?OPTIONS? ?PATHS ...?
**
** Report the change status of files in the current check-out. If one or
** more PATHS are specified, only changes among the named files and
** directories are reported. Directories are searched recursively.
**
** The status command is similar to the changes command, except it lacks
** several of the options supported by changes and it has its own header
** and footer information. The header information is a subset of that
** shown by the info command, and the footer shows if there are any forks.
** Change type classification is always enabled for the status command.
**
** Each line of output is the name of a changed file, with paths shown
** according to the "relative-paths" setting, unless overridden by the
** --abs-paths or --rel-paths options.
**
** By default, all changed files are selected for display. This behavior
** can be overridden by using one or more filter options (listed below),
** in which case only files with the specified change type(s) are shown.
** As a special case, the --no-merge option does not inhibit this default.
** This default shows exactly the set of changes that would be checked-
** in by the commit command.
**
** If no filter options are used, or if the --merge option is used, the
** artifact hash of each merge contributor check-in version is displayed at
** the end of the report. The --no-merge option is useful to display the
** default set of changed files without the merge contributors.
**
** If change type classification is enabled, each output line starts with
** a code describing the file's change type, e.g. EDITED or RENAMED. It
** is enabled by default unless exactly one change type is selected. For
** the purposes of determining the default, --changed counts as selecting
** one change type. The default can be overridden by the --classify or
** --no-classify options.
**
** --edited and --updated produce disjoint sets. --updated shows a file
** only when it is identical to that of its merge contributor, and the
** change type classification is UPDATED_BY_MERGE or UPDATED_BY_INTEGRATE.
** If the file had to be merged with any other changes, it is considered
** to be merged or conflicted and therefore will be shown by --edited, not
** --updated, with types EDITED or CONFLICT. The --changed option can be
** used to display the union of --edited and --updated.
**
** --differ is so named because it lists all the differences between the
** checked-out version and the check-out directory. In addition to the
** default changes (excluding --merge), it lists extra files which (if
** ignore-glob is set correctly) may be worth adding. Prior to doing a
** commit, it is good practice to check --differ to see not only which
** changes would be committed but also if any files should be added.
**
** If both --merge and --no-merge are used, --no-merge has priority. The
** same is true of --classify and --no-classify.
**
** The "fossil changes --extra" command is equivalent to "fossil extras".
**
** General options:
** --abs-paths Display absolute pathnames
** -b|--brief Show a single keyword for the status
** --rel-paths Display pathnames relative to the current working
** directory
** --hash Verify file status using hashing rather than
** relying on file mtimes
** --case-sensitive BOOL Override case-sensitive setting
** --dotfiles Include unmanaged files beginning with a dot
** --ignore <CSG> Ignore unmanaged files matching CSG glob patterns
**
** Options specific to the changes command:
** --header Identify the repository if report is non-empty
** -v|--verbose Say "(none)" if the change report is empty
** --classify Start each line with the file's change type
** --no-classify Do not print file change types
**
** Filter options:
** --edited Display edited, merged, and conflicted files
** --updated Display files updated by merge/integrate
** --changed Combination of the above two options
** --missing Display missing files
** --added Display added files
** --deleted Display deleted files
** --renamed Display renamed files
** --conflict Display files having merge conflicts
** --meta Display files with metadata changes
** --unchanged Display unchanged files
** --all Display all managed files, i.e. all of the above
** --extra Display unmanaged files
** --differ Display modified and extra files
** --merge Display merge contributors
** --no-merge Do not display merge contributors

** The --age option displays file commit times. Like -r, --age has the
** side effect of making -t sort by commit time, not modification time.
**
** The -v option provides extra information about each file. Without -r,
** -v displays the change status, in the manner of the changes command.
** With -r, -v shows the commit time and size of the checked-in files.
**
** The -t option changes the sort order. Without -t, files are sorted by
** path and name (case insensitive sort if -r). If neither --age nor -r
** are used, -t sorts by modification time, otherwise by commit time.
**
** Options:
** --age Show when each file was committed
** --hash With -v, verify file status using hashing
** rather than relying on file sizes and mtimes
** -r VERSION The specific check-in to list
** -R|--repository REPO Extract info from repository REPO
** -t Sort output in time order
** --tree Tree format
** -v|--verbose Provide extra information about each file

** COMMAND: clean
**
** Usage: %fossil clean ?OPTIONS? ?PATH ...?
**
** Delete all "extra" files in the source tree. "Extra" files are files
** that are not officially part of the check-out. If one or more PATH
** arguments appear, then only the files named, or files contained with
** directories named, will be removed.
**
** If the --prompt option is used, prompts are issued to confirm the
** permanent removal of each file. Otherwise, files are backed up to the
** undo buffer prior to removal, and prompts are issued only for files
** whose removal cannot be undone due to their large size or due to
** --disable-undo being used.
**
** The --force option treats all prompts as having been answered yes,
** whereas --no-prompt treats them as having been answered no.
**
** Files matching any glob pattern specified by the --clean option are
** deleted without prompting, and the removal cannot be undone.
**
** No file that matches glob patterns specified by --ignore or --keep will
** ever be deleted. Files and subdirectories whose names begin with "."
** are automatically ignored unless the --dotfiles option is used.
**
** The default values for --clean, --ignore, and --keep are determined by
** the (versionable) clean-glob, ignore-glob, and keep-glob settings.
**
** The --verily option ignores the keep-glob and ignore-glob settings and
** turns on --force, --emptydirs, --dotfiles, and --disable-undo. Use the
** --verily option when you really want to clean up everything. Extreme
** care should be exercised when using the --verily option.
**
** Options:
** --allckouts Check for empty directories within any check-outs
** that may be nested within the current one. This
** option should be used with great care because the
** empty-dirs setting (and other applicable settings)
** belonging to the other repositories, if any, will
** not be checked.
** --case-sensitive BOOL Override case-sensitive setting
** --dirsonly Only remove empty directories. No files will
** be removed. Using this option will automatically
** enable the --emptydirs option as well.
** --disable-undo WARNING: This option disables use of the undo
** mechanism for this clean operation and should be
** used with extreme caution.
** --dotfiles Include files beginning with a dot (".")
** --emptydirs Remove any empty directories that are not
** explicitly exempted via the empty-dirs setting
** or another applicable setting or command line
** argument. Matching files, if any, are removed
** prior to checking for any empty directories;
** therefore, directories that contain only files
** that were removed will be removed as well.
** -f|--force Remove files without prompting
** -i|--prompt Prompt before removing each file. This option
** implies the --disable-undo option.
** -x|--verily WARNING: Removes everything that is not a managed
** file or the repository itself. This option
** implies the --force, --emptydirs, --dotfiles, and
** --disable-undo options. Furthermore, it
** completely disregards the keep-glob
** and ignore-glob settings. However, it does honor
** the --ignore and --keep options.
** --clean CSG WARNING: Never prompt to delete any files matching
** this comma separated list of glob patterns. Also,
** deletions of any files matching this pattern list
** cannot be undone.
** --ignore CSG Ignore files matching patterns from the
** comma separated list of glob patterns
** --keep <CSG> Keep files matching this comma separated
** list of glob patterns
** -n|--dry-run Delete nothing, but display what would have been
** deleted
** --no-prompt Do not prompt the user for input and assume an
** answer of 'No' for every question
** --temp Remove only Fossil-generated temporary files
** -v|--verbose Show all files as they are removed

**
** Usage: %fossil commit ?OPTIONS? ?FILE...?
** or: %fossil ci ?OPTIONS? ?FILE...?
**
** Create a new version containing all of the changes in the current
** check-out. You will be prompted to enter a check-in comment unless
** the comment has been specified on the command-line using "-m" or a
** file containing the comment using -M. The editor defined in the
** "editor" fossil option (see %fossil help set) will be used, or from
** the "VISUAL" or "EDITOR" environment variables (in that order) if
** no editor is set.
**
** All files that have changed will be committed unless some subset of
** files is specified on the command line.
**
** The --branch option followed by a branch name causes the new
** check-in to be placed in a newly-created branch with the name
** passed to the --branch option.
**
** Use the --branchcolor option followed by a color name (ex:
** '#ffc0c0') to specify the background color of entries in the new
** branch when shown in the web timeline interface. The use of
** the --branchcolor option is not recommended. Instead, let Fossil
** choose the branch color automatically.
**
** The --bgcolor option works like --branchcolor but only sets the
** background color for a single check-in. Subsequent check-ins revert
** to the default color.
**
** A check-in is not permitted to fork unless the --allow-fork option
** appears. An empty check-in (i.e. with nothing changed) is not
** allowed unless the --allow-empty option appears. A check-in may not
** be older than its ancestor unless the --allow-older option appears.
** If any of files in the check-in appear to contain unresolved merge
** conflicts, the check-in will not be allowed unless the
** --allow-conflict option is present. In addition, the entire
** check-in process may be aborted if a file contains content that
** appears to be binary, Unicode text, or text with CR/LF line endings
** unless the interactive user chooses to proceed. If there is no
** interactive user or these warnings should be skipped for some other
** reason, the --no-warnings option may be used. A check-in is not
** allowed against a closed leaf.
**
** If a commit message is blank, you will be prompted:
** ("continue (y/N)?") to confirm you really want to commit with a
** blank commit message. The default value is "N", do not commit.
**
** The --private option creates a private check-in that is never synced.
** Children of private check-ins are automatically private.
**
** The --tag option applies the symbolic tag name to the check-in.
**
** The --hash option detects edited files by computing each file's
** artifact hash rather than just checking for changes to its size or mtime.
**
** Options:
** --allow-conflict Allow unresolved merge conflicts
** --allow-empty Allow a commit with no changes
** --allow-fork Allow the commit to fork
** --allow-older Allow a commit older than its ancestor
** --baseline Use a baseline manifest in the commit process
** --bgcolor COLOR Apply COLOR to this one check-in only
** --branch NEW-BRANCH-NAME Check in to this new branch
** --branchcolor COLOR Apply given COLOR to the branch
** --close Close the branch being committed
** --date-override DATETIME DATE to use instead of 'now'
** --delta Use a delta manifest in the commit process
** --hash Verify file status using hashing rather
** than relying on file mtimes
** --ignore-clock-skew If a clock skew is detected, ignore it and
** behave as if the user had entered 'yes' to
** the question of whether to proceed despite
** the skew.
** --ignore-oversize Do not warning the user about oversized files
** --integrate Close all merged-in branches
** -m|--comment COMMENT-TEXT Use COMMENT-TEXT as commit comment
** -M|--message-file FILE Read the commit comment from given file
** --mimetype MIMETYPE Mimetype of check-in comment
** -n|--dry-run If given, display instead of run actions
** -v|--verbose Show a diff in the commit message prompt
** --no-prompt This option disables prompting the user for
** input and assumes an answer of 'No' for every
** question.
** --no-warnings Omit all warnings about file contents
** --no-verify Do not run before-commit hooks
** --nosign Do not attempt to sign this commit with gpg
** --nosync Do not auto-sync prior to committing
** --override-lock Allow a check-in even though parent is locked
** --private Do not sync changes and their descendants
** --tag TAG-NAME Assign given tag TAG-NAME to the check-in
** --trace Debug tracing
** --user-override USER USER to use instead of the current default
**
** DATETIME may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in
** year-month-day form, it may be truncated, the "T" may be replaced by
** a space, and it may also name a timezone offset from UTC as "-HH:MM"
** (westward) or "+HH:MM" (eastward). Either no timezone suffix or "Z"
** means UTC.

** COMMAND: checkout*
** COMMAND: co#

** Usage: %fossil checkout ?VERSION | --latest? ?OPTIONS?

**
** NOTE: Most people use "fossil update" instead of "fossil checkout" for
** day-to-day operations. If you are new to Fossil and trying to learn your
** way around, it is recommended that you become familiar with the
** "fossil update" command first.
**
** This command changes the current check-out to the version specified
** as an argument. The command aborts if there are edited files in the
** current check-out unless the --force option is used. The --keep option
** leaves files on disk unchanged, except the manifest and manifest.uuid
** files.
**
** The --latest flag can be used in place of VERSION to check-out the
** latest version in the repository.
**
** Options:
** --force Ignore edited files in the current check-out
** --keep Only update the manifest file(s)
** --force-missing Force check-out even if content is missing
** --setmtime Set timestamps of all files to match their SCM-side
** times (the timestamp of the last check-in which modified
** them)

** COMMAND: clone
**
** Usage: %fossil clone ?OPTIONS? URI ?FILENAME?
**
** Make a clone of a repository specified by URI in the local
** file named FILENAME. If FILENAME is omitted, then an appropriate
** filename is deduced from last element of the path in the URL.
**
** URI may be one of the following forms ([...] denotes optional elements):
**
** * HTTP/HTTPS protocol:
**
** http[s]://[userid[:password]@]host[:port][/path]
**
** * SSH protocol:
**
** ssh://[userid@]host[:port]/path/to/repo.fossil[?fossil=path/fossil.exe]
**
** * Filesystem:
**
** [file://]path/to/repo.fossil
**
** For ssh and filesystem, path must have an extra leading
** '/' to use an absolute path.
**
** Use %HH escapes for special characters in the userid and
** password. For example "%40" in place of "@", "%2f" in place
** of "/", and "%3a" in place of ":".
**
** Note that in Fossil (in contrast to some other DVCSes) a repository
** is distinct from a check-out. Cloning a repository is not the same thing
** as opening a repository. This command always clones the repository. This
** command might also open the repository, but only if the --no-open option
** is omitted and either the --workdir option is included or the FILENAME
** argument is omitted. Use the separate [[open]] command to open a
** repository that was previously cloned and already exists on the
** local machine.
**
** By default, the current login name is used to create the default
** admin user for the new clone. This can be overridden using
** the -A|--admin-user parameter.
**
** Options:
** -A|--admin-user USERNAME Make USERNAME the administrator
** -B|--httpauth USER:PASS Add HTTP Basic Authorization to requests
** --nested Allow opening a repository inside an opened
** check-out
** --nocompress Omit extra delta compression
** --no-open Clone only. Do not open a check-out.
** --once Don't remember the URI.
** --private Also clone private branches
** --save-http-password Remember the HTTP password without asking
** -c|--ssh-command SSH Use SSH as the "ssh" command
** --ssl-identity FILENAME Use the SSL identity if requested by the server
** --transport-command CMD Use CMD to move messages to the server and back
** -u|--unversioned Also sync unversioned content
** -v|--verbose Show more statistics in output
** --workdir DIR Also open a check-out in DIR
** --xverbose Extra debugging output
**
** See also: [[init]], [[open]]

** Newly created buttons are <span> elements with an SVG background icon,

**
** To simplify customization, the only properties modified for HTML-defined

** needs to be called to attach the "onclick" handler (done automatically from
** a handler attached to the "DOMContentLoaded" event).
**
** The initialization functions do not overwrite the "data-copytarget" and
** "data-copylength" attributes with empty or null values for <idTarget> and
** <cchLength>, respectively. Set <cchLength> to "-1" to explicitly remove the
** previous copy length limit.

**
** About Database Write Protection
** -------------------------------
**
** This is *not* a primary means of defending the application from
** attack. Fossil should be secure even if this mechanism is disabled.
** The purpose of database write protection is to provide an additional
** layer of defense in case SQL injection bugs somehow slip into other
** parts of the system. In other words, database write protection is
** not the primary defense but rather defense in depth.
**
** This mechanism mostly focuses on the USER table, to prevent an
** attacker from giving themselves Admin privilegs, and on the
** CONFIG table and especially "sensitive" settings such as
** "diff-command" or "editor" that if compromised by an attacker
** could lead to an RCE.
**
** By default, the USER and CONFIG tables are read-only. Various
** subsystems that legitimately need to change those tables can
** temporarily do so using:
**
** db_unprotect(PROTECT_xxx);
** // make the legitmate changes here
** db_protect_pop();
**
** Code that runs inside of reduced protections should be carefully
** reviewed to ensure that it is harmless and not subject to SQL
** injection.
**
** Read-only operations (such as many web pages like /timeline)
** can invoke db_protect(PROTECT_ALL) to effectively make the database
** read-only. TEMP tables (which are often used for these kinds of
** pages) are still writable, however.
**
** The PROTECT_SENSITIVE protection is a subset of PROTECT_CONFIG
** that blocks changes to all of the global_config table, but only
** "sensitive" settings in the config table. PROTECT_SENSITIVE
** relies on triggers and the protected_setting() SQL function to
** prevent changes to sensitive settings.
**
** PROTECT_READONLY is set for any HTTP request for which the HTTP_REFERER
** is not the same origin. This is an additional defense against cross-site-
** scripting attacks. As with all of these defenses, this is only an extra
** backup layer. Fossil should be proof against XSS attacks even without this.
**
** Any violation of these security restrictions results in a SECURITY message
** in the server log (if enabled). A violation of any of these restrictions
** probably indicates a bug in Fossil and should be reported to the
** developers.
**
** Additional Notes
** ----------------
**
** Calls to routines like db_set() and db_unset() temporarily disable
** the PROTECT_CONFIG protection. The assumption is that these calls
** cannot be invoked by an SQL injection and are thus safe. Make sure
** this is the case by always using a string literal as the name argument
** to db_set() and db_unset() and friend, not a variable that might
** be compromised by an attack.

**
** By default, your current login name is used to create the default

**
** By default, all settings will be initialized to their default values.

** repository is used, almost all of the settings accessible from the setup
** page, either directly or indirectly, will be copied. Normal users and
** their associated permissions will not be copied; however, the system
** default users "anonymous", "nobody", "reader", "developer", and their
** associated permissions will be copied. In case of SQL errors, rebuild the
** template repository and try again.
**
** Options:
** --template FILE Copy settings from repository file
** -A|--admin-user USERNAME Select given USERNAME as admin user
** --date-override DATETIME Use DATETIME as time of the initial check-in
** --sha1 Use an initial hash policy of "sha1"
** --project-name STRING The name of the project "project name in
** quotes"
** --project-desc STRING The description of the project "project

**
** DATETIME may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in

** a space, and it may also name a timezone offset from UTC as "-HH:MM"

** COMMAND: open
**
** Usage: %fossil open REPOSITORY ?VERSION? ?OPTIONS?
**
** Open a new connection to the repository name REPOSITORY. A check-out
** for the repository is created with its root at the current working
** directory, or in DIR if the "--workdir DIR" is used. If VERSION is
** specified then that version is checked out. Otherwise the most recent
** check-in on the main branch (usually "trunk") is used.
**
** REPOSITORY can be the filename for a repository that already exists on the
** local machine or it can be a URI for a remote repository. If REPOSITORY
** is a URI in one of the formats recognized by the [[clone]] command, then
** remote repo is first cloned, then the clone is opened. The clone will be
** stored in the current directory, or in DIR if the "--repodir DIR" option
** is used. The name of the clone will be taken from the last term of the URI.
** For "http:" and "https:" URIs, you can append an extra term to the end of
** the URI to get any repository name you like. For example:
**
** fossil open https://fossil-scm.org/home/new-name
**
** The base URI for cloning is "https://fossil-scm.org/home". The extra
** "new-name" term means that the cloned repository will be called
** "new-name.fossil".
**
** Options:
** --empty Initialize check-out as being empty, but still connected
** with the local repository. If you commit this check-out,
** it will become a new "initial" commit in the repository.
** -f|--force Continue with the open even if the working directory is
** not empty, or if auto-sync fails.
** --force-missing Force opening a repository with missing content
** -k|--keep Only modify the manifest file(s)
** --nested Allow opening a repository inside an opened check-out
** --nosync Do not auto-sync the repository prior to opening even
** if the autosync setting is on.
** --repodir DIR If REPOSITORY is a URI that will be cloned, store
** the clone in DIR rather than in "."
** --setmtime Set timestamps of all files to match their SCM-side
** times (the timestamp of the last check-in which modified
** them).
** --verbose If passed a URI then this flag is passed on to the clone
** operation, otherwise it has no effect
** --workdir DIR Use DIR as the working directory instead of ".". The DIR
** directory is created if it does not exist.
**
** See also: [[close]], [[clone]]

** COMMAND: settings

** Usage: %fossil settings ?SETTING? ?VALUE? ?OPTIONS?

**
** The "settings" command with no arguments lists all settings and their
** values. With just a SETTING name it shows the current value of that setting.
** With a VALUE argument it changes the property for the current repository.
**
** Settings marked as versionable are overridden by the contents of the
** file named .fossil-settings/PROPERTY in the check-out root, if that
** file exists.
**
** The "unset" command clears a setting.
**
** Settings can have both a "local" repository-only value and "global" value
** that applies to all repositories. The local values are stored in the
** "config" table of the repository and the global values are stored in the
** configuration database. If both a local and a global value exists for a
** setting, the local value takes precedence. This command normally operates
** on the local settings. Use the --global option to change global settings.
**
** Options:
** --global Set or unset the given property globally instead of
** setting or unsetting it for the open repository only
** --exact Only consider exact name matches
** --value Only show the value of a given property (implies --exact)

** Create a new delta.
**
** The delta is written into a preallocated buffer, zDelta, which
** should be at least 60 bytes longer than the target file, zOut.
** The delta string will be NUL-terminated, but it might also contain
** embedded NUL characters if either the zSrc or zOut files are
** binary. This function returns the length of the delta string
** in bytes, excluding the final NUL terminator character.
**
** Output Format:
**
** The delta begins with a base64 number followed by a newline. This
** number is the number of bytes in the TARGET file. Thus, given a
** delta file z, a program can compute the size of the output file
** simply by reading the first line and decoding the base-64 number
** found there. The delta_output_size() routine does exactly this.
**
** After the initial size number, the delta consists of a series of
** literal text segments and commands to copy from the SOURCE file.
** A copy command looks like this:
**
** NNN@MMM,
**
** where NNN is the number of bytes to be copied and MMM is the offset
** into the source file of the first byte (both base-64). If NNN is 0
** it means copy the rest of the input file. Literal text is like this:
|
| ︙ | ︙ | |||
273 274 275 276 277 278 279 | ** Next we begin scanning the target file using a sliding 16-byte ** window. The hash of the 16-byte window in the target is used to ** search for a matching section in the source file. When a match ** is found, a copy command is added to the delta.

**
** Schema:

** CREATE TABLE delta_parse(
** op TEXT,

** );
**
** Given an input DELTA, this function parses the delta and returns
** rows for each entry in the delta. The op column has one of the
** values SIZE, COPY, INSERT, CHECKSUM, ERROR.
**
** Assuming no errors, the first row has op='SIZE'. a1 is the size of
** the output in bytes and a2 is NULL.
**
** After the initial SIZE row, there are zero or more 'COPY' and/or 'INSERT'
** rows. A COPY row means content is copied from the source into the
** output. Column a1 is the number of bytes to copy and a2 is the offset
** into source from which to begin copying. An INSERT row means to
** insert text into the output stream. Column a1 is the number of bytes
** to insert and column is a BLOB that contains the text to be inserted.
**
** The last row of a well-formed delta will have an op value of 'CHECKSUM'.
** The a1 column will be the value of the checksum and a2 will be NULL.
**
** If the input delta is not well-formed, then a row with an op value
** of 'ERROR' is returned. The a1 value of the ERROR row is the offset
** into the delta where the error was encountered and a2 is NULL.

/* This formatter generates a unified diff for HTML.
**
** The result is a <table> with four columns. The four columns hold:
**
** 1. The line numbers for the first file.
** 2. The line numbers for the second file.
** 3. The "diff mark": "+" or "-" or just a space
** 4. Text of the line
**
** Inserted lines are marked with <ins> and deleted lines are marked
** with <del>. The whole line is marked this way, not just the part that
** changed. The part that change has an additional nested <ins> or <del>.
** The CSS needs to be set up such that a single <ins> or <del> gives a
** light background and a nested <ins> or <del> gives a darker background.
** Additional attributes (like bold font) might also be added to nested
** <ins> and <del> since those are the characters that have actually
** changed.
**
** Accumulator strategy:
**
** * Delete line numbers are output directly to p->pOut
** * Insert line numbers accumulate in p->aCol[0].
** * Separator marks accumulate in p->aCol[1].
** * Change text accumulates in p->aCol[2].
** * Pending insert line numbers go into p->aCol[3].
** * Pending insert text goes into p->aCol[4].
**
** eState is 1 if text has an open <del>

** A common subsequence between p->aFrom and p->aTo has been found.
** This routine tries to judge if the subsequence really is a valid
** match or rather is just an artifact of an indentation change.
**
** Return non-zero if the subsequence is valid. Return zero if the
** subsequence seems likely to be an editing artifact and should be
** ignored.
**
** This routine is a heuristic optimization intended to give more
** intuitive diff results following an indentation change it code that
** is formatted similarly to C/C++, Javascript, Go, TCL, and similar
** languages that use {...} for nesting. A correct diff is computed
** even if this routine always returns true (non-zero). But sometimes
** a more intuitive diff can result if this routine returns false.
**
** The subsequences consists of the rows iSX through iEX-1 (inclusive)
** in p->aFrom[]. The total sequences is iS1 through iE1-1 (inclusive)
** of p->aFrom[].
**
** Example where this heuristic is useful, see the diff at
** https://www.sqlite.org/src/fdiff?v1=0e79dd15cbdb4f48&v2=33955a6fd874dd97
**
** See also discussion at https://fossil-scm.org/forum/forumpost/9ba3284295
**
** ALGORITHM (subject to change and refinement):
**
** 1. If the subsequence is larger than 1/7th of the original span,
** then consider it valid. --> return 1
**
** 2. If no lines of the subsequence contains more than one
** non-whitespace character, --> return 0
**
** 3. If any line of the subsequence contains more than one non-whitespace
** character and is unique across the entire sequence after ignoring
** leading and trailing whitespace --> return 1
**
** 4. Otherwise, it is potentially an artifact of an indentation
** change. --> return 0

** COMMAND: diff

** Usage: %fossil diff|gdiff ?OPTIONS? ?FILE1? ?FILE2 ...?
**
** Show the difference between the current version of each of the FILEs
** specified (as they exist on disk) and that same file as it was checked-
** out. Or if the FILE arguments are omitted, show all unsaved changes
** currently in the working check-out.
**
** The default output format is a "unified patch" (the same as the
** output of "diff -u" on most unix systems). Many alternative formats
** are available. A few of the more useful alternatives:
**
** --tk Pop up a Tcl/Tk-based GUI to show the diff
** --by Show a side-by-side diff in the default web browser
** -b Show a linear diff in the default web browser
** -y Show a text side-by-side diff
** --webpage Format output as HTML
** --webpage -y HTML output in the side-by-side format
**
** The "--from VERSION" option is used to specify the source check-in
** for the diff operation. If not specified, the source check-in is the
** base check-in for the current check-out. Similarly, the "--to VERSION"
** option specifies the check-in from which the second version of the file
** or files is taken. If there is no "--to" option then the (possibly edited)
** files in the current check-out are used. The "--checkin VERSION" option
** shows the changes made by check-in VERSION relative to its primary parent.
** The "--branch BRANCHNAME" shows all the changes on the branch BRANCHNAME.
**
** The "-i" command-line option forces the use of Fossil's own internal
** diff logic rather than any external diff program that might be configured
** using the "setting" command. If no external diff program is configured,
** then the "-i" option is a no-op. The "-i" option converts "gdiff" into
** "diff".
**
** The "--diff-binary" option enables or disables the inclusion of binary files
** when using an external diff program.
**
** The "--binary" option causes files matching the glob PATTERN to be treated
** as binary when considering if they should be used with the external diff
** program. This option overrides the "binary-glob" setting.
**
** These command show differences between managed files. Use the "fossil xdiff"
** command to see differences in unmanaged files.
**
** Options:
** --binary PATTERN Treat files that match the glob PATTERN
** as binary
** --branch BRANCH Show diff of all changes on BRANCH
** --brief Show filenames only
** -b|--browser Show the diff output in a web-browser
** --by Shorthand for "--browser -y"
** -ci|--checkin VERSION Show diff of all changes in VERSION
** --command PROG External diff program. Overrides "diff-command"
** -c|--context N Show N lines of context around each change,
** with negative N meaning show all content
** --dark Use dark mode for the Tcl/Tk-based GUI and HTML
** --diff-binary BOOL Include binary files with external commands
** --exec-abs-paths Force absolute path names on external commands
** --exec-rel-paths Force relative path names on external commands
** -r|--from VERSION Select VERSION as source for the diff
** -w|--ignore-all-space Ignore white space when comparing lines
** -i|--internal Use internal diff logic
** --invert Invert the diff
** --json Output formatted as JSON
** -n|--linenum Show line numbers
** -N|--new-file Alias for --verbose
** --numstat Show only the number of added and deleted lines
** -y|--side-by-side Side-by-side diff
** --strip-trailing-cr Strip trailing CR
** --tcl Tcl-formated output used internally by --tk
** --tclsh PATH Tcl/Tk shell used for --tk (default: "tclsh")
** --tk Launch a Tcl/Tk GUI for display
** --to VERSION Select VERSION as target for the diff
** --undo Diff against the "undo" buffer
** --unified Unified diff
** -v|--verbose Output complete text of added or deleted files
** -h|--versions Show compared versions in the diff header
** --webpage Format output as a stand-alone HTML webpage
** -W|--width N Width of lines in side-by-side diff
** -Z|--ignore-trailing-space Ignore changes to end-of-line whitespace

**
** The entries in aCommand[] are in sorted order by name. Since webpage names

** WEBPAGE: uv
** WEBPAGE: doc
** URL: /uv/FILE
** URL: /doc/CHECKIN/FILE
**
** CHECKIN can be either tag or hash prefix or timestamp identifying a
** particular check-in, or the name of a branch (meaning the most recent
** check-in on that branch) or one of various magic words:
**
** "tip" means the most recent check-in
**
** "ckout" means the current check-out, if the server is run from
** within a check-out, otherwise it is the same as "tip"
**
** "latest" means use the most recent check-in for the document
** regardless of what branch it occurs on.
**
** FILE is the name of a file to delivered up as a webpage. FILE is relative
** to the root of the source tree of the repository. The FILE must
** be a part of CHECKIN, except when CHECKIN=="ckout" when FILE is read
** directly from disk and need not be a managed file. For /uv, FILE
** can also be the hash of the unversioned file.
**
** The "ckout" CHECKIN is intended for development - to provide a mechanism
** for looking at what a file will look like using the /doc webpage after
** it gets checked in. Some commands like "fossil ui", "fossil server",
** and "fossil http" accept an argument "--ckout-alias NAME" when allows
** NAME to be understood as an alias for "ckout". On a site with many
** embedded hyperlinks to /doc/trunk/... one can run with "--ckout-alias trunk"
** to simulate what the pending changes will look like after they are
** checked in. The NAME alias is stored in g.zCkoutAlias.
**
** The file extension is used to decide how to render the file.
**
** If FILE ends in "/" then the names "FILE/index.html", "FILE/index.wiki",
** and "FILE/index.md" are tried in that order. If the binary was compiled
** with TH1 embedded documentation support and the "th1-docs" setting is
** enabled, the name "FILE/index.th1" is also tried. If none of those are
** found, then FILE is completely replaced by "404.md" and tried. If that
** is not found, then a default 404 screen is generated.
**
** If the file's mimetype is "text/x-fossil-wiki" or "text/x-markdown"
** then headers and footers are added. If the document has mimetype
** text/html then headers and footers are usually not added. However,
** if a "text/html" document begins with the following div:
**
** <div class='fossil-doc' data-title='TEXT'>
**
** then headers and footers are supplied. The optional data-title field
** specifies the title of the document in that case.
**
** For fossil-doc documents and for markdown documents, text of the
** form: "href='$ROOT/" or "action='$ROOT" has the $ROOT name expanded
** to the top-level of the repository.

*******************************************************************************
**
** This file implements ETags: cache control for Fossil
**
** An ETag is a hash that encodes attributes which must be the same for
** the page to continue to be valid. Attributes that might be contained
** in the ETag include:
**
** (1) The mtime on the Fossil executable
** (2) The last change to the CONFIG table
** (3) The last change to the EVENT table
** (4) The value of the display cookie
** (5) A hash value supplied by the page generator
** (6) The details of the request URI
** (7) The name user as determined by the login cookie
**
** Item (1) is always included in the ETag. The other elements are
** optional. Because (1) is always included as part of the ETag, all
** outstanding ETags can be invalidated by touching the fossil executable.
**
** A page generator routine invokes etag_check() exactly once, with
** arguments that indicates which of the above elements to include in the
** hash. If the request contained an If-None-Match header which matches
** the generated ETag, then a 304 Not Modified reply is generated and
** the process exits. In other words, etag_check() never returns. But
** if there is no If-None_Match header or if the ETag does not match,
** then etag_check() returns normally. Later, during reply generation,
** the cgi.c module will invoke etag_tag() to recover the generated tag
** and include it in the reply header.
**
** 2018-02-25:
**
** Also support Last-Modified: and If-Modified-Since:. The
** etag_last_modified(mtime) API records a timestamp for the page in
** seconds since 1970. This causes a Last-Modified: header to be
** issued in the reply. Or, if the request contained If-Modified-Since:
** and the new mtime is not greater than the mtime associated with
** If-Modified-Since, then a 304 Not Modified reply is generated and
** the etag_last_modified() API never returns.

** COMMAND: git*
**
** Usage: %fossil git SUBCOMMAND
**
** Do incremental import or export operations between Fossil and Git.
** Subcommands:
**
** > fossil git export [MIRROR] [OPTIONS]
**
** Write content from the Fossil repository into the Git repository
** in directory MIRROR. The Git repository is created if it does not
** already exist. If the Git repository does already exist, then
** new content added to fossil since the previous export is appended.
**
** Repeat this command whenever new check-ins are added to the Fossil
** repository in order to reflect those changes into the mirror. If
** the MIRROR option is omitted, the repository from the previous
** invocation is used.
**
** The MIRROR directory will contain a subdirectory named
** ".mirror_state" that contains information that Fossil needs to
** do incremental exports. Do not attempt to manage or edit the files
** in that directory since doing so can disrupt future incremental
** exports.
**
** Options:
** --autopush URL Automatically do a 'git push' to URL. The
** URL is remembered and used on subsequent exports
** to the same repository. Or if URL is "off" the
** auto-push mechanism is disabled
** --debug FILE Write fast-export text to FILE rather than
** piping it into "git fast-import"
** -f|--force Do the export even if nothing has changed
** --if-mirrored No-op if the mirror does not already exist
** --limit N Add no more than N new check-ins to MIRROR.
** Useful for debugging
** --mainbranch NAME Use NAME as the name of the main branch in Git.
** The "trunk" branch of the Fossil repository is
** mapped into this name. "master" is used if
** this option is omitted.
** -q|--quiet Reduce output. Repeat for even less output.
** -v|--verbose More output
**
** > fossil git import MIRROR
**
** TBD...
**
** > fossil git status
**
** Show the status of the current Git mirror, if there is one.
**
** -q|--quiet No output if there is nothing to report

** and each file it touches
** -n|--dry-run Outputs which files would require touching,
** but does not touch them
** -q|--quiet Suppress warnings, e.g. when skipping unmanaged
** or out-of-tree files
**
** Only one of --now, --checkin, and --checkout may be used. The

** A so-called "single-file/mini/web check-in" is a slimmed-down form
** of the check-in command which accepts only a single file and is
** intended to accept edits to a file via the web interface or from
** the CLI from outside of a check-out.
**
** Being fully non-interactive is a requirement for this function,
** thus it cannot perform autosync or similar activities (which
** includes checking for repo locks).
**
** This routine uses the state from the given fully-populated pCI
** argument to add pCI->fileContent to the database, and create and
** save a manifest for that change. Ownership of pCI and its contents
** are unchanged.
**
** This function may may modify pCI as follows:
**
** - If one of Manifest pCI->pParent or pCI->zParentUuid are NULL,
** then the other will be assigned based on its counterpart. Both
** may not be NULL.
**
** - pCI->zDate is normalized to/replaced with a valid date/time
** string. If its original value cannot be validated then
** this function fails. If pCI->zDate is NULL, the current time
** is used.
**
** - If the CIMINI_CONVERT_EOL_INHERIT flag is set,
** pCI->fileContent appears to be plain text, and its line-ending
** style differs from its previous version, it is converted to the
** same EOL style as the previous version. If this is done, the
** pCI->fileHash is re-computed. Note that only pCI->fileContent,
** not the original file, is affected by the conversion.
**
** - Else if one of the CIMINI_CONVERT_EOL_WINDOWS or
** CIMINI_CONVERT_EOL_UNIX flags are set, pCI->fileContent is
** converted, if needed, to the corresponding EOL style.
**
** - If EOL conversion takes place, pCI->fileHash is re-calculated.
**
** - If pCI->fileHash is empty, this routine populates it with the
** repository's preferred hash algorithm (after any EOL conversion).
**
** - pCI->comment may be converted to Unix-style newlines.
**
** pCI's ownership is not modified.
**
** This function validates pCI's state and fails if any validation
** fails.
**
** On error, returns false (0) and, if pErr is not NULL, writes a
** diagnostic message there.
**
** Returns true on success. If pRid is not NULL, the RID of the
** resulting manifest is written to *pRid.
**
** The check-in process is largely influenced by pCI->flags, and that
** must be populated before calling this. See the fossil_cimini_flags
** enum for the docs for each flag.

**
** Usage: %fossil test-ci-mini ?OPTIONS? FILENAME
**
** where FILENAME is a repo-relative name as it would appear in the
** vfile table.
**
** Options:
** -R|--repository REPO The repository file to commit to
** --as FILENAME The repository-side name of the input
** file, relative to the top of the
** repository. Default is the same as the
** input file name.
** -m|--comment COMMENT Required check-in comment
** -M|--comment-file FILE Reads check-in comment from the given file
** -r|--revision VERSION Commit from this version. Default is
** the check-out version (if available) or
** trunk (if used without a check-out).
** --allow-fork Allows the commit to be made against a
** non-leaf parent. Note that no autosync
** is performed beforehand.
** --allow-merge-conflict Allows check-in of a file even if it
** appears to contain a fossil merge conflict
** marker
** --user-override USER USER to use instead of the current
** default
** --date-override DATETIME DATE to use instead of 'now'
** --allow-older Allow a commit to be older than its
** ancestor
** --convert-eol-inherit Convert EOL style of the check-in to match
** the previous version's content
** --convert-eol-unix Convert the EOL style to Unix
** --convert-eol-windows Convert the EOL style to Windows.
** (Only one of the --convert-eol-X options may be used and they only
** modified the saved blob, not the input file.)
** --delta Prefer to generate a delta manifest, if
** able. The forbid-delta-manifests repo
** config option trumps this, as do certain
** heuristics.
** --allow-new-file Allow addition of a new file this way.
** Disabled by default to avoid that case-
** sensitivity errors inadvertently lead to
** adding a new file where an update is
** intended.
** -d|--dump-manifest Dumps the generated manifest to stdout
** immediately after it's generated
** --save-manifest FILE Saves the generated manifest to a file
** after successfully processing it
** --wet-run Disables the default dry-run mode
**
** Example:
**
** %fossil test-ci-mini -R REPO -m ... -r foo --as src/myfile.c myfile.c

/*
** COMMAND: finfo
**
** Usage: %fossil finfo ?OPTIONS? FILENAME
**
** Print the complete change history for a single file going backwards
** in time. The default mode is -l.
**
** For the -l|--log mode: If "-b|--brief" is specified one line per revision
** is printed, otherwise the full comment is printed. The "-n|--limit N"
** and "--offset P" options limits the output to the first N changes
** after skipping P changes.
**
** The -i mode will print various facts about FILENAME, including its
** hash and the check-in and time when the current version of the file
** was created. Use -v for additional information. Add the -r VERSION
** option to see similar information about the same file for the check-in
** specified by VERSION.
**
** In the -s mode prints the status as <status> <revision>. This is
** a quick status and does not check for up-to-date-ness of the file.
**
** In the -p mode, there's an optional flag "-r|--revision REVISION".
** The specified version (or the latest checked-out version) is printed
** to stdout. The -p mode is another form of the "cat" command.
**
** Options:
** -b|--brief Display a brief (one line / revision) summary
** --case-sensitive B Enable or disable case-sensitive filenames. B is a
** boolean: "yes", "no", "true", "false", etc.
** -i|--id Print the artifact ID
** -l|--log Select log mode (the default)
** -n|--limit N Display the first N changes (default unlimited).
** N less than 0 means no limit.
** --offset P Skip P changes
** -p|--print Select print mode
** -r|--revision R Print the given revision (or ckout, if none is given)
** to stdout (only in print mode)
** -s|--status Select status mode (print a status indicator for FILE)
** -v|--verbose On the -i option, show all check-ins that use the
** file, not just the earliest check-in
** -W|--width N Width of lines (default is to auto-detect). Must be
** more than 22 or else 0 to indicate no limit.
**
** See also: [[artifact]], [[cat]], [[descendants]], [[info]], [[leaves]]

*******************************************************************************
**
** This routine implements eponymous virtual table for SQLite that gives
** all of the files associated with a single check-in. The table works
** as a table-valued function.
**
** The source code filename "foci" is short for "Files of Check-in".
**
** Usage example:
**
** SELECT * FROM files_of_checkin('trunk');
**
** The "schema" for the temp.foci table is:
**
** CREATE TABLE files_of_checkin(
** checkinID INTEGER, -- RID for the check-in manifest
** filename TEXT, -- Name of a file
** uuid TEXT, -- hash of the file
** previousName TEXT, -- Name of the file in previous check-in
** perm TEXT, -- Permissions on the file
** symname TEXT HIDDEN -- Symbolic name of the check-in.
** );
**
** The hidden symname column is (optionally) used as a query parameter to
** identify the particular check-in to parse. The checkinID parameter
** (such is a unique numeric RID rather than symbolic name) can also be used
** to identify the check-in. Example:
**
** SELECT * FROM files_of_checkin
** WHERE checkinID=symbolic_name_to_rid('trunk');
**

** Closes or re-opens the given forum RID via addition of a new

** cancelled, except as noted below. zReason is ignored if doClose is
** false or if zReason is NULL or starts with a NUL byte.
**
** This function only adds a "closed" tag if forum_rid_is_closed()
** indicates that frid's head is not closed. If a parent post is
** already closed, no tag is added. Similarly, it will only remove a
** "closed" tag from a post which has its own "closed" tag, and will
** not remove an inherited one from a parent post.
**
** If doClose is true and frid is closed (directly or inherited), this
** is a no-op. Likewise, if doClose is false and frid itself is not
** closed (not accounting for an inherited closed tag), this is a
** no-op.
**
** Returns true if it actually creates a new tag, else false. Fails
** fatally on error. If it returns true then any ForumPost::iClosed
** values from previously loaded posts are invalidated if they refer
** to the amended post or a response to it.
**
** Sidebars:
**
** - Unless the caller has a transaction open, via
** db_begin_transaction(), there is a very tiny race condition
** window during which the caller's idea of whether or not the forum
** post is closed may differ from the current repository state.
**
** - This routine assumes that frid really does refer to a forum post.
**
** - This routine assumes that frid is not private or pending
** moderation.
**
** - Closure of a forum post requires a propagating "closed" tag to
** account for how edits of posts are handled. This differs from
** closure of a branch, where a non-propagating tag is used.

/**************************************************************
Confirmer is a utility which provides an alternative to confirmation
dialog boxes and "check this checkbox to confirm action" widgets. It
acts by modifying a button to require two clicks within a certain
time, with the second click acting as a confirmation of the first. If
the second click does not come within a specified timeout then the
action is not confirmed.
Usage:
fossil.confirmer(domElement, options);
Usually:
fossil.confirmer(element, {
onconfirm: function(){
// this === the element.
// Do whatever the element would normally do when
// clicked.
}
});
Options:
.initialText = initial text of the element. Defaults to the result
of the element's .value (for INPUT tags) or innerHTML (for
everything else). After the timeout/tick count expires, or if the
user confirms the operation, the element's text is re-set to this
value.
.confirmText = text to show when in "confirm mode".
Default=("Confirm: "+initialText), or something similar.
.timeout = Number of milliseconds to wait for confirmation.
Default=3000. Alternately, use a combination of .ticks and
.ticktime.
.onconfirm = function to call when clicked in confirm mode. Default
= undefined. The function's "this" is the DOM element to which
the countdown applies.
.ontimeout = function to call when confirm is not issued. Default =
undefined. The function's "this" is the DOM element to which the
countdown applies.
.onactivate = function to call when item is clicked, but only if the
item is not currently in countdown mode. This is called (and must
return) before the countdown starts. The function's "this" is the
DOM element to which the countdown applies. This can be used, e.g.,
to change the element's text or CSS classes.
.classInitial = optional CSS class string (default='') which is
added to the element during its "initial" state (the state it is in
when it is not waiting on a timeout). When the target is activated
(waiting on a timeout) this class is removed. In the case of a
timeout, this class is added *before* the .ontimeout handler is
called.
.classWaiting = optional CSS class string (default='') which is
added to the target when it is waiting on a timeout. When the target
leaves timeout-wait mode, this class is removed. When timeout-wait
mode is entered, this class is added *before* the .onactivate
handler is called.
.ticktime = a number of ms to wait per tick (see the next item).
Default = 1000.
.ticks = a number of "ticks" to wait, as an alternative to .timeout.
When this mode is active, the ontick callback will be triggered
immediately before each tick, including the first one. If both
.ticks and .timeout are set, only one will be used, but which one is
unspecified. If passed a ticks value with a truncated integer value
of 0 or less, it will throw an exception (e.g. that also applies if
it's passed 0.5).
.ontick = when using .ticks, this callback is passed the current
tick number before each tick, and its "this" is the target
element. On each subsequent call, the tick count will be reduced by
1, and it is passed 0 after the final tick expires or when the
action has been confirmed, immediately before the onconfirm or
ontimeout callback. The intention of the callback is to update the
label of the target element. If .ticks is set but .ontick is not
then a default implementation is used which updates the element with
the .confirmText, prepending a countdown to it.
.pinSize = if true AND confirmText is set, calculate the larger of
the element's original and confirmed size and pin it to the larger
of those sizes to avoid layout reflows when confirmation is
running. The pinning is implemented by setting its minWidth and
maxWidth style properties to the same value. This does not work if
the element text is updated dynamically via ontick(). This ONLY
works if the element is in the DOM and is not hidden (e.g. via
display:none) at the time this routine is called, otherwise we
cannot calculate its size. If the element needs to be hidden, hide
it after initializing the confirmer.
.debug = boolean. If truthy, it sends some debug output to the dev
console to track what it's doing.
Various notes:
- To change the default option values, modify the
fossil.confirmer.defaultOpts object.
- Exceptions triggered via the callbacks are caught and emitted to the
dev console if the debug option is enabled, but are otherwise
ignored.
- Due to the nature of multi-threaded code, it is potentially possible
that confirmation and timeout actions BOTH happen if the user
triggers the associated action at "just the right millisecond"
before the timeout is triggered.
TODO:
- Add an invert option which activates if the timeout is reached and
"times out" if the element is clicked again. e.g. a button which says
"Saving..." and cancels the op if it's clicked again, else it saves
after X time/ticks.
- Internally we save/restore the initial text of non-INPUT elements
using a relatively expensive bit of DOMParser hoop-jumping. We
"should" instead move their child nodes aside (into an internal
out-of-DOM element) and restore them as needed.
Terse Change history:
- 20200811
- Added pinSize option.
- 20200507:
- Add a tick-based countdown in order to more easily support
updating the target element with the countdown.
- 20200506:
- Ported from jQuery to plain JS.
- 20181112:
- extended to support certain INPUT elements.
- made default opts configurable.
- 20070717: initial jQuery-based impl.

(function(F/*fossil object*/){
/**
A basic API for creating and managing a copy-to-clipboard button.
Requires: fossil.bootstrap, fossil.dom
*/
const D = F.dom;
/**
Initializes element e as a copy button using the given options
object.
The first argument may be a DOM element or a string (CSS selector
suitable for use with document.querySelector()).
Options:
.copyFromElement: DOM element
.copyFromId: DOM element ID
.extractText: optional callback which is triggered when the copy
button is clicked. It must return the text to copy to the
clipboard. The default is to extract it from the copy-from
element, using its [value] member, if it has one, else its
[innerText]. A client-provided callback may use any data source
it likes, so long as it's synchronous. If this function returns a
falsy value then the clipboard is not modified. This function is
called with the fully expanded/resolved options object as its
"this" (that's a different instance than the one passed to this
function!).
At least one of copyFromElement, copyFromId, or extractText must
be provided, but if copyFromId is not set and e.dataset.copyFromId
is then that value is used in its place. extractText() trumps the
other two options.
.cssClass: optional CSS class, or list of classes, to apply to e.
.style: optional object of properties to copy directly into
e.style.
.oncopy: an optional callback function which is added as an event
listener for the 'text-copied' event (see below). There is
functionally no difference from setting this option or adding a
'text-copied' event listener to the element, and this option is
considered to be a convenience form of that. For the sake of
framework-level consistency, the default value is a callback
which passes the copy button to fossil.dom.flashOnce().
Note that this function's own defaultOptions object holds default
values for some options. Any changes made to that object affect
any future calls to this function.
Be aware that clipboard functionality might or might not be
available in any given environment. If this button appears to
have no effect, that may be because it is not enabled/available
in the current platform.
The copy button emits custom event 'text-copied' after it has
successfully copied text to the clipboard. The event's "detail"
member is an object with a "text" property holding the copied
text. Other properties may be added in the future. The event is
not fired if copying to the clipboard fails (e.g. is not
available in the current environment).
As a special case, the copy button's click handler is suppressed
(becomes a no-op) for as long as the element has the CSS class
"disabled". This allows elements which cannot be disabled via
HTML attributes, e.g. a SPAN, to act as a copy button while still
providing a way to disable them.
Returns the copy-initialized element.
Example:
const button = fossil.copyButton('#my-copy-button', {
copyFromId: 'some-other-element-id'
});
button.addEventListener('text-copied',function(ev){
fossil.dom.flashOnce(ev.target);
console.debug("Copied text:",ev.detail.text);
});

Uses the /jchunk AJAX route to fetch specific lines of a given
artifact. The argument must be an Object suitable for passing as
the second argument to fossil.fetch(). Its urlParams property
must be an object with these properties:
{
name: full hash of the target file,
from: first 1-based line number of the file to fetch (inclusive),
to: last 1-based line number of the file to fetch (inclusive)
}
The fetchOpt object is NOT cloned for use by the call: it is used
as-is and may be modified by this call. Thus callers "really
should" pass a temporary object, not a long-lived one.
If fetchOpt does not define any of the (beforesend, aftersend,
onerror) callbacks, the defaults from fossil.diff.config.chunkFetch
are used, so any given client page may override those to provide
page-level default handling.
Note that onload callback is ostensibly optional but this
function is not of much use without an onload
handler. Conversely, the default onerror handler is often
customized on a per-page basis to send the error output somewhere
where the user can see it.
The response, on success, will be an array of strings, each entry
being one line from the requested artifact. If the 'to' line is
greater than the length of the file, the array will be shorter
than (to-from) lines.
The /jchunk route reports errors via JSON objects with
an "error" string property describing the problem.
This is an async operation. Returns the fossil object.

/**
Sets up pseudo-automatic content preview handling between a
source element (typically a TEXTAREA) and a target rendering
element (typically a DIV). The selector argument must be one of:
- A single DOM element
- A collection of DOM elements with a forEach method.
- A CSS selector
Each element in the collection must have the following data
attributes:
- data-f-preview-from: is either a DOM element id, WITH a leading
'#' prefix, or the name of a method (see below). If it's an ID,
the DOM element must support .value to get the content.
- data-f-preview-to: the DOM element id of the target "previewer"
element, WITH a leading '#', or the name of a method (see below).
- data-f-preview-via: the name of a method (see below).
- OPTIONAL data-f-preview-as-text: a numeric value. Explained below.
Each element gets a click handler added to it which does the
following:
1) Reads the content from its data-f-preview-from element or, if
that property refers to a method, calls the method without
arguments and uses its result as the content.
2) Passes the content to
methodNamespace[f-data-post-via](content,callback). f-data-post-via
is responsible for submitting the preview HTTP request, including
any parameters the request might require. When the response
arrives, it must pass the content of the response to its 2nd
argument, an auto-generated callback installed by this mechanism
which...
3) Assigns the response text to the data-f-preview-to element or
passes it to the function
methodNamespace[f-data-preview-to](content), as appropriate. If
data-f-preview-to is a DOM element and data-f-preview-as-text is
'0' (the default) then the target elements contents are replaced
with the given content as HTML, else the content is assigned to
the target's textContent property. (Note that this routine uses
DOMParser, rather than assignment to innerHTML, to apply
HTML-format content.)
The methodNamespace (2nd argument) defaults to fossil.page, and
any method-name data properties, e.g. data-f-preview-via and
potentially data-f-preview-from/to, must be a single method name,
not a property-access-style string. e.g. "myPreview" is legal but
"foo.myPreview" is not (unless, of course, the method is actually
named "foo.myPreview" (which is legal but would be
unconventional)). All such methods are called with
methodNamespace as their "this".
An example...
First an input button:
<button id='test-preview-connector'
data-f-preview-from='#fileedit-content-editor' // elem ID or method name
data-f-preview-via='myPreview' // method name
data-f-preview-to='#fileedit-tab-preview-wrapper' // elem ID or method name
>Preview update</button>
And a sample data-f-preview-via method:
fossil.page.myPreview = function(content,callback){
const fd = new FormData();
fd.append('foo', ...);
fossil.fetch('preview_forumpost',{
payload: fd,
onload: callback,
onerror: (e)=>{ // only if app-specific handling is needed
fossil.fetch.onerror(e); // default impl
... any app-specific error reporting ...
}
});
};
Then connect the parts with:
fossil.connectPagePreviewers('#test-preview-connector');
Note that the data-f-preview-from, data-f-preview-via, and
data-f-preview-to selector are not resolved until the button is
actually clicked, so they need not exist in the DOM at the
instant when the connection is set up, so long as they can be
resolved when the preview-refreshing element is clicked.
Maintenance reminder: this method is not strictly part of
fossil.dom, but is in its file because it needs access to
dom.parseHtml() to avoid an innerHTML assignment and all code
which uses this routine also needs fossil.dom.

/**
fetch() is an HTTP request/response mini-framework
similar (but not identical) to the not-quite-ubiquitous
window.fetch().
JS usages:
fossil.fetch( URI [, onLoadCallback] );
fossil.fetch( URI [, optionsObject = {}] );
Noting that URI must be relative to the top of the repository and
should not start with a slash (if it does, it is stripped). It gets
the equivalent of "%R/" prepended to it.
The optionsObject may be an onload callback or an object with any
of these properties:
- onload: callback(responseData) (default = output response to the
console). In the context of the callback, the options object is
"this", noting that this call may have amended the options object
with state other than what the caller provided.
- onerror: callback(Error object) (default = output error message
to console.error() and fossil.error()). Triggered if the request
generates any response other than HTTP 200, suffers a connection
error or timeout while awaiting a response, or if the onload()
handler throws an exception. In the context of the callback, the
options object is "this". Note that this function is intended to be
used solely for error reporting, not error recovery. Because
onerror() may be called if onload() throws, it is up to the caller
to ensure that their onerror() callback references only state which
is valid in such a case.
- method: 'POST' | 'GET' (default = 'GET'). CASE SENSITIVE!
- payload: anything acceptable by XHR2.send(ARG) (DOMString,
Document, FormData, Blob, File, ArrayBuffer), or a plain object or
array, either of which gets JSON.stringify()'d. If payload is set
then the method is automatically set to 'POST'. By default XHR2
will set the content type based on the payload type. If an
object/array is converted to JSON, the contentType option is
automatically set to 'application/json', and if JSON.stringify() of
that value fails then the exception is propagated to this
function's caller.
- contentType: Optional request content type when POSTing. Ignored
if the method is not 'POST'.
- responseType: optional string. One of ("text", "arraybuffer",
"blob", or "document") (as specified by XHR2). Default = "text".
As an extension, it supports "json", which tells it that the
response is expected to be text and that it should be JSON.parse()d
before passing it on to the onload() callback. If parsing of such
an object fails, the onload callback is not called, and the
onerror() callback is passed the exception from the parsing error.
- urlParams: string|object. If a string, it is assumed to be a
URI-encoded list of params in the form "key1=val1&key2=val2...",
with NO leading '?'. If it is an object, all of its properties get
converted to that form. Either way, the parameters get appended to
the URL before submitting the request.
- responseHeaders: If true, the onload() callback is passed an
additional argument: a map of all of the response headers. If it's
a string value, the 2nd argument passed to onload() is instead the
value of that single header. If it's an array, it's treated as a
list of headers to return, and the 2nd argument is a map of those
header values. When a map is passed on, all of its keys are
lower-cased. When a given header is requested and that header is
set multiple times, their values are (per the XHR docs)
concatenated together with ", " between them.
- beforesend/aftersend: optional callbacks which are called
without arguments immediately before the request is submitted
and immediately after it is received, regardless of success or
error. In the context of the callback, the options object is
the "this". These can be used to, e.g., keep track of in-flight
requests and update the UI accordingly, e.g. disabling/enabling
DOM elements. Any exceptions thrown in an beforesend are passed
to the onerror() handler and cause the fetch() to prematurely
abort. Exceptions thrown in aftersend are currently silently
ignored (feature or bug?).
- timeout: integer in milliseconds specifying the XHR timeout
duration. Default = fossil.fetch.timeout.
When an options object does not provide
onload/onerror/beforesend/aftersend handlers of its own, this
function falls back to defaults which are member properties of this
function with the same name, e.g. fossil.fetch.onload(). The
default onload/onerror implementations route the data through the
dev console and (for onerror()) through fossil.error(). The default
beforesend/aftersend are no-ops. Individual pages may overwrite
those members to provide default implementations suitable for the
page's use, e.g. keeping track of how many in-flight ajax requests
are pending.
Note that this routine may add properties to the 2nd argument, so
that instance should not be kept around for later use.
Returns this object, noting that the XHR request is asynchronous,
and still in transit (or has yet to be sent) when that happens.

do NOT scroll because doing so would interrupt
them. There are middle grounds here where the user will

seems to work out okay. If there was no previous message,
assume we don't have any messages yet and go ahead and
scroll this message into view (noting that that scrolling
is hypothetically a no-op in such cases).
The wrench in these works are posts with IMG tags, as
those images are loaded async and the element does not
yet have enough information to know how far to scroll!
For such cases we have to delay the scroll until the

/**
Client-side implementation of the /filepage app. Requires that
the fossil JS bootstrapping is complete and that several fossil
JS APIs have been installed: fossil.fetch, fossil.dom,
fossil.tabs, fossil.storage, fossil.confirmer.
Custom events which can be listened for via
fossil.page.addEventListener():
- Event 'fileedit-file-loaded': passes on information when it
loads a file (whether from the network or its internal local-edit
cache), in the form of an "finfo" object:
{
filename: string,
checkin: UUID string,
branch: branch name of UUID,
isExe: bool, true only for executable files
mimetype: mimetype string, as determined by the fossil server.
}
The internal docs and code frequently use the term "finfo", and such
references refer to an object with that form.
The fossil.page.fileContent() method gets or sets the current file
content for the page.
- Event 'fileedit-committed': is fired when a commit completes,
passing on the same info as fileedit-file-loaded.
- Event 'fileedit-content-replaced': when the editor's content is
replaced, as opposed to it being edited via user
interaction. This normally happens via selecting a file to
load. The event detail is the fossil.page object, not the current
file content.
- Event 'fileedit-preview-updated': when the preview is refreshed
from the server, this event passes on information about the preview
change in the form of an object:
{
element: the DOM element which contains the content preview.
mimetype: the fossil-reported content mimetype.
previewMode: a string describing the preview mode: see
the fossil.page.previewModes map for the values. This can
be used to determine whether, e.g., the content is suitable
for applying a 3rd-party code highlighting API to.
}
Here's an example which can be used with the highlightjs code
highlighter to update the highlighting when the preview is
refreshed in "wiki" mode (which includes fossil-native wiki and
markdown):
fossil.page.addEventListener(
'fileedit-preview-updated',
(ev)=>{
if(ev.detail.previewMode==='wiki'){
ev.detail.element.querySelectorAll(
'code[class^=language-]'
).forEach((e)=>hljs.highlightBlock(e));
}
}

$stash is an internal-use-only object for managing "stashed"
local edits, to help avoid that users accidentally lose content
by switching tabs or following links or some such. The basic
theory of operation is...
All "stashed" state is stored using fossil.storage.
- When the current file content is modified by the user, the
current stathe of the current P.finfo and its the content
is stashed. For the built-in editor widget, "changes" is
notified via a 'change' event. For a client-side custom
widget, the client needs to call P.stashContentChange() when
their widget triggers the equivalent of a 'change' event.
- For certain non-content updates (as of this writing, only the
is-executable checkbox), only the P.finfo stash entry is
updated, not the content (unless the content has not yet been
stashed, in which case it is also stashed so that the stash
always has matching pairs of finfo/content).
- When saving, the stashed entry for the previous version is removed
from the stash.
- When "loading", we use any stashed state for the given
checkin/file combination. When forcing a re-load of content,
any stashed entry for that combination is removed from the
stash.
- Every time P.stashContentChange() updates the stash, it is
pruned to $stash.prune.defaultMaxCount most-recently-updated
entries.
- This API often refers to "finfo objects." Those are objects
with a minimum of {checkin,filename} properties (which must be
valid), and a combination of those two properties is used as
basis for the stash keys for any given checkin/filename
combination.
The structure of the stash is a bit convoluted for efficiency's
sake: we store a map of file info (finfo) objects separately from
those files' contents because otherwise we would be required to
JSONize/de-JSONize the file content when stashing/restoring it,
and that would be horribly inefficient (meaning "battery-consuming"
on mobile devices).

from the index entries to avoid having to JSONize/de-JSONize
the content. The assumption/hope is that the browser can store
those records "directly," without any intermediary
encoding/decoding going on.

Keep track of how many in-flight AJAX requests there are so we
can disable input elements while any are pending. For
simplicity's sake we simply disable ALL OF IT while any AJAX is
pending, rather than disabling operation-specific UI elements,
which would be a huge maintenance hassle.
Noting, however, that this global on/off is not *quite*
pedantically correct. Pedantically speaking. If an element is
disabled before an XHR starts, this code "should" notice that and
not include it in the to-re-enable list. That would be annoying
to do, and becomes impossible to do properly once multiple XHRs
are in transit and an element is disabled seprately between two
of those in-transit requests (that would be an unlikely, but
possible, corner case). As of this writing, the only elements
which are ever normally programmatically toggled between
enabled/disabled...
1) Belong to the file selection list and remain disabled until
the list of leaves and files are loaded. i.e. they would be
disabled *anyway* during their own XHR requests.
2) The stashWidget's SELECT list when no local edits are
stashed. Curiously, the all-or-nothing re-enabling implemented
here does not re-enable that particular selection list. That's
because of timing, though: that widget is "manually" disabled
when the list is empty, and that list is normally emptied in
conjunction with an XHR request.

* A special care should be taken if some intermediate edits are hidden.

/**
Client-side implementation of the /wikiedit app. Requires that
the fossil JS bootstrapping is complete and that several fossil
JS APIs have been installed: fossil.fetch, fossil.dom,
fossil.tabs, fossil.storage, fossil.confirmer, fossil.popupwidget.
Custom events which can be listened for via
fossil.page.addEventListener():
- Event 'wiki-page-loaded': passes on information when it
loads a wiki (whether from the network or its internal local-edit
cache), in the form of an "winfo" object:
{
name: string,
mimetype: mimetype string,
type: "normal" | "tag" | "checkin" | "branch" | "sandbox",
version: UUID string or null for a sandbox page or new page,
parent: parent UUID string or null if no parent,
isEmpty: true if page has no content (is "deleted").
content: string, optional in most contexts
}
The internal docs and code frequently use the term "winfo", and such
references refer to an object with that form.
The fossil.page.wikiContent() method gets or sets the current
file content for the page.
- Event 'wiki-saved': is fired when a commit completes,
passing on the same info as wiki-page-loaded.
- Event 'wiki-content-replaced': when the editor's content is
replaced, as opposed to it being edited via user
interaction. This normally happens via selecting a file to
load. The event detail is the fossil.page object, not the current
file content.
- Event 'wiki-preview-updated': when the preview is refreshed
from the server, this event passes on information about the preview
change in the form of an object:
{
element: the DOM element which contains the content preview.
mimetype: the page's mimetype.
}
Here's an example which can be used with the highlightjs code
highlighter to update the highlighting when the preview is
refreshed in "wiki" mode (which includes fossil-native wiki and
markdown):
fossil.page.addEventListener(
'wiki-preview-updated',
(ev)=>{
if(ev.detail.mimetype!=='text/plain'){
ev.detail.element.querySelectorAll(
'code[class^=language-]'
).forEach((e)=>hljs.highlightBlock(e));
}
}
);

/**
$stash is an internal-use-only object for managing "stashed"
local edits, to help avoid that users accidentally lose content
by switching tabs or following links or some such. The basic
theory of operation is...
All "stashed" state is stored using fossil.storage.
- When the current wiki content is modified by the user, the
current state of the page is stashed.
- When saving, the stashed entry for the previous version is
removed from the stash.
- When "loading", we use any stashed state for the given
checkin/file combination. When forcing a re-load of content,
any stashed entry for that combination is removed from the
stash.
- Every time P.stashContentChange() updates the stash, it is
pruned to $stash.prune.defaultMaxCount most-recently-updated
entries.
- This API often refers to "winfo objects." Those are objects
with a minimum of {page,mimetype} properties (which must be
valid), and the page name is used as basis for the stash keys
for any given page.
The structure of the stash is a bit convoluted for efficiency's
sake: we store a map of file info (winfo) objects separately from
those files' contents because otherwise we would be required to
JSONize/de-JSONize the file content when stashing/restoring it,
and that would be horribly inefficient (meaning "battery-consuming"
on mobile devices).
*/
const $stash = {
keys: {
index: F.page.name+'.index'

/**
index: {
"PAGE_NAME": {wiki page info w/o content}
...
}
In F.storage we...
- Store this.index under the key this.keys.index.
- Store each page's content under the key
(P.name+'/PAGE_NAME'). These are stored separately from the
index entries to avoid having to JSONize/de-JSONize the
content. The assumption/hope is that the browser can store
those records "directly," without any intermediary

/**
Initializes pikchr-rendered elements with the ability to
toggle between their SVG and source code.
The first argument may be any of:
- A single SVG.pikchr element.
- A collection (with a forEach method) of such elements.
- A CSS selector string for one or more such elements.
- An array of such strings.
Passing no value is equivalent to passing 'svg.pikchr'.
For each SVG in the resulting set, this function sets up event
handlers which allow the user to toggle the SVG between image and
source code modes. The image will switch modes in response to
cltr-click and, if its *parent* element has the "toggle" CSS
class, it will also switch modes in response to single-click.
If the parent element has the "source" CSS class, the image
starts off with its source code visible and the image hidden,
instead of the default of the other way around.
Returns this object.
Each element will only be processed once by this routine, even if
it is passed to this function multiple times. Each processed
element gets a "data" attribute set to it to indicate that it was
already dealt with.
This code expects the following structure around the SVGs, and
will not process any which don't match this:
<DIV.pikchr-wrapper>
<DIV.pikchr-svg><SVG.pikchr></SVG></DIV>
<DIV.pikchr-src>

Quirks of this ^^^ design:
We use only a single slot in sessionStorage. We could
alternately use a key like pikchr-$pId and pass that key on
to /pikchrshow via fromSession=pikchr-$pId, but that would
eventually lead to stale session entries if loading of
pikchrshow were interrupted at an untimely point. The
down-side of _not_ doing that is that some user (or
automation) options multiple "open in pikchrshow" links
rapidly enough, the will open the same pikchr (the one which
was stored in the session's slot most recently). The
current approach should be fine for normal human interaction
speeds, but if it proves to be a problem we can instead use
the above-described approach of storing each pikchr in its
own session slot and simply accept that there may be stale
entries at some point.

/**
A very basic tooltip-like widget. It's intended to be popped up
to display basic information or basic user interaction
components, e.g. a copy-to-clipboard button.
Requires: fossil.bootstrap, fossil.dom
*/
const D = F.dom;
/**
Creates a new tooltip-like widget using the given options object.
Options:
.refresh: callback which is called just before the tooltip is
revealed. It must refresh the contents of the tooltip, if needed,
by applying the content to/within this.e, which is the base DOM
element for the tooltip (and is a child of document.body). If the
contents are static and set up via the .init option then this
callback is not needed. When moving an already-shown tooltip,
this is *not* called. It arguably should be, but the fact is that
we often have to show() a popup twice in a row without hiding it
between those calls: once to get its computed size and another to
move it by some amount relative to that size. If the state of the
popup depends on its position and a "double-show()" is needed
then the client must hide() the popup between the two calls to
show() in order to force a call to refresh() on the second
show().
.adjustX: an optional callback which is called when the tooltip
is to be displayed at a given position and passed the X
viewport-relative coordinate. This routine must either return its
argument as-is or return an adjusted value. The intent is to
allow a given tooltip may be positioned more appropriately for a
given context, if needed (noting that the desired position can,
and probably should, be passed to the show() method
instead). This class's API assumes that clients give it
viewport-relative coordinates, and it will take care to translate
those to page-relative, so this callback should not do so.
.adjustY: the Y counterpart of adjustX.
.init: optional callback called one time to initialize the state
of the tooltip. This is called after the this.e has been created
and added (initially hidden) to the DOM. If this is called, it is
removed from the object immediately after it is called.
All callback options are called with the PopupWidget object as
their "this".
.cssClass: optional CSS class, or list of classes, to apply to
the new element. In addition to any supplied here (or inherited
from the default), the class "fossil-PopupWidget" is always set
in order to allow certain app-internal CSS to account for popup
windows in special cases.
.style: optional object of properties to copy directly into
the element's style object.
The options passed to this constructor get normalized into a
separate object which includes any default values for options not
provided by the caller. That object is available this the
resulting PopupWidget's options property. Default values for any
options not provided by the caller are pulled from
PopupWidget.defaultOptions, and modifying those affects all
future calls to this method but has no effect on existing
instances.
Example:
const tip = new fossil.PopupWidget({
init: function(){
// optionally populate DOM element this.e with the widget's
// content.
},
refresh: function(){
// (re)populate/refresh the contents of the main
// wrapper element, this.e.
}
});
tip.show(50, 100);
// ^^^ viewport-relative coordinates. See show() for other options.

A prefix which gets internally applied to all fossil.storage
property keys so that localStorage and sessionStorage across the
same browser profile instance do not "leak" across multiple repos
being hosted by the same origin server. Such polination is still
there but, with this key prefix applied, it won't be immediately
visible via the storage API.
With this in place we can justify using localStorage instead of
sessionStorage again.
One implication, it was discovered after the release of 2.12, of
using localStorage and sessionStorage, is that their scope (the
same "origin" and client application/profile) allows multiple
repos on the same origin to use the same storage. Thus a user
editing a wiki in /repoA/wikiedit could then see those edits in
/repoB/wikiedit. The data do not cross user- or browser
boundaries, though, so it "might" arguably be called a bug. Even
so, it was never intended for that to happen. Rather than lose
localStorage access altogether, storageKeyPrefix was added so
that we can sandbox that state for the various repos.
See: https://fossil-scm.org/forum/forumpost/4afc4d34de
Sidebar: it might seem odd to provide a key prefix and stick all
properties in the topmost level of the storage object. We do that
because adding a layer of object to sandbox each repo would mean
(de)serializing that whole tree on every storage property change
(and we update storage often during editing sessions).
e.g. instead of storageObject.projectName.foo we have
storageObject[storageKeyPrefix+'foo']. That's soley for
efficiency's sake (in terms of battery life and
environment-internal storage-level effort). Even so, it might (or
might not) be useful to do that someday.

Initializes the tabs associated with the given tab container
(DOM element or selector for a single element). This must be
called once before using any other member functions of a given
instance, noting that the constructor will call this if it is
passed an argument.
The tab container must have an 'id' attribute. This function
looks through the DOM for all elements which have
data-tab-parent=thatId. For each one it creates a button to
switch to that tab and moves the element into this.e.tabs,
*possibly* injecting an intermediary element between
this.e.tabs and the element.
The label for each tab is set by the data-tab-label attribute
of each element, defaulting to something not terribly useful.
When it's done, it auto-selects the first tab unless a tab has
a truthy numeric value in its data-tab-select attribute, in
which case the last tab to have such a property is selected.
This method must only be called once per instance. TabManagers
may be nested but must not share any tabs instances.

DOM elements of potential interest to users:
this.e.container = the outermost container element.
this.e.tabBar = the button bar. Each "button" (whether it's a
buttor not is unspecified) has a class of .tab-button.
this.e.tabs = the parent for all of the tab elements.
It is legal, within reason, to manipulate these a bit, in
particular this.e.container, e.g. by adding more children to
it. Do not remove elements from the tabs or tabBar, however, or
the tab state may get sorely out of sync.
CSS classes: the container element has whatever class(es) the
client sets on. this.e.tabBar gets the 'tab-bar' class and
this.e.tabs gets the 'tabs' class. It's hypothetically possible
to move the tabs to either side or the bottom using only CSS,
but it's never been tested.

/**
A slight adaptation of fossil's legacy wysiwyg wiki editor which
makes it usable with the newer editor's edit widget replacement
API.
Requires: window.fossil, fossil.dom, and that the current page is
/wikiedit. If called from another page it returns without effect.
Caveat: this is an all-or-nothing solution. That is, once plugged
in to /wikiedit, it cannot be removed without reloading the page.
That is a limitation of the current editor-widget-swapping API.

** COMMAND: fusefs*
**
** Usage: %fossil fusefs [--debug] DIRECTORY
**
** This command uses the Fuse Filesystem (FuseFS) to mount a directory
** at DIRECTORY that contains the content of all check-ins in the
** repository. The names of files are DIRECTORY/checkins/VERSION/PATH
** where DIRECTORY is the root of the mount, VERSION is any valid
** check-in name (examples: "trunk" or "tip" or a tag or any unique
** prefix of an artifact hash, etc) and PATH is the pathname of the file in
** the check-in. If DIRECTORY does not exist, then an attempt is made
** to create it.
**
** The DIRECTORY/checkins directory is not searchable so one cannot
** do "ls DIRECTORY/checkins" to get a listing of all possible check-in
** names. There are countless variations on check-in names and it is
** impractical to list them all. But all other directories are searchable
** and so the "ls" command will work everywhere else in the fusefs
** file hierarchy.
**
** The FuseFS typically only works on Linux, and then only on Linux
** systems that have the right kernel drivers and have installed the
** appropriate support libraries.
**
** After stopping the "fossil fusefs" command, it might also be necessary
** to run "fusermount -u DIRECTORY" to reset the FuseFS before using it
** again.

**
** This file contains code to connect Fossil to libFuzzer. Do a web search
** for "libfuzzer" for details about that fuzzing platform.
**
** To build on linux (the only platform for which this works at
** present) first do
**
** ./configure
**
** Then edit the Makefile as follows:
**
** (1) Change CC to be "clang-6.0" or some other compiler that
** supports libFuzzer
**
** (2) Change APPNAME to "fossil-fuzz"
**
** (3) Add "-fsanitize=fuzzer" and "-DFOSSIL_FUZZ" to TCCFLAGS. Perhaps
** make the first change "-fsanitize=fuzzer,undefined,address" for
** extra, but slower, testing.
**
** Then build the fuzzer using:
**
** make clean fossil-fuzz
**
** To run the fuzzer, create a working directory ("cases"):
**
** mkdir cases
**
** Then seed the working directory with example input files. For example,
** if fuzzing the wiki formatter, perhaps copy *.wiki into cases. Then
** run the fuzzer thusly:
**
** fossil-fuzz cases
**
** The default is to fuzz the Fossil-wiki translator. Use the --fuzztype TYPE
** option to fuzz different aspects of the system.

/* Notes:
**
** The graph is laid out in 1 or more "rails". A "rail" is a vertical
** band in the graph in which one can place nodes or arrows connecting
** nodes. There can be between 1 and GR_MAX_RAIL rails. If the graph
** is too complex to be displayed in GR_MAX_RAIL rails, it is omitted.
**
** A "riser" is the thick line that comes out of the top of a node and
** goes up to the next node on the branch, or to the top of the screen.
** A "descender" is a thick line that comes out of the bottom of a node
** and proceeds down to the bottom of the page.
**
** A "merge riser" is a thin line going up out of a node to indicate a
** merge or cherrypick. (Cherrypicks are drawn with thin dashed lines.
** Merges are drawn with thin solid lines.) A "merge riser" might go
** stright up out of the top of a leaf node, but for non-leaves, they
** go horizontally to their assigned rail first, then up.
**
** Invoke graph_init() to create a new GraphContext object. Then
** call graph_add_row() to add nodes, one by one, to the graph.
** Nodes must be added in display order, from top to bottom.
** Then invoke graph_render() to run the layout algorithm. The
** layout algorithm computes which rail each nodes sit on, and
** the rails used for merge arrows.

/* This module contains javascript needed to render timeline graphs in Fossil.
**
** There can be multiple graphs on a single webpage, but this script is only
** loaded once.
**
** Prior to sourcing this script, there should be a separate
** <script type='application/json' id='timeline-data-NN'> for each graph,
** each containing JSON like this:
**
** { "iTableId": INTEGER, // Table sequence number (NN)
** "circleNodes": BOOLEAN, // True for circle nodes. False for squares
** "showArrowheads": BOOLEAN, // True for arrowheads. False to omit
** "iRailPitch": INTEGER, // Spacing between vertical lines (px)
** "colorGraph": BOOLEAN, // True to put color on graph lines
** "nomo": BOOLEAN, // True to join merge lines with rails
** "iTopRow": INTEGER, // Index of top-most row in the graph
** "omitDescenders": BOOLEAN, // Omit ancestor lines off bottom of screen
** "fileDiff": BOOLEAN, // True for file diff. False for check-in
** "scrollToSelect": BOOLEAN, // Scroll to selection on first render
** "nrail": INTEGER, // Number of vertical "rails"
** "baseUrl": TEXT, // Top-level URL
** "dwellTimeout": INTEGER, // Tooltip show delay in milliseconds
** "closeTimeout": INTEGER, // Tooltip close delay in milliseconds
** "hashDigits": INTEGER, // Limit of tooltip hashes ("hash-digits")
** "rowinfo": ROWINFO-ARRAY }
**
** The rowinfo field is an array of structures, one per entry in the timeline,
** where each structure has the following fields:
**
** id: The id of the <div> element for the row. This is an integer.
** to get an actual id, prepend "m" to the integer. The top node
** is iTopRow and numbers increase moving down the timeline.
** bg: The background color for this row
** r: The "rail" that the node for this row sits on. The left-most
** rail is 0 and the number increases to the right.
** d: If exists and true then there is a "descender" - an arrow
** coming from the bottom of the page straight up to this node.
** mo: "merge-out". If it exists, this is the rail position
** for the upward portion of a merge arrow. The merge arrow goes as
** a solid normal merge line up to the row identified by "mu" and
** then as a dashed cherrypick merge line up further to "cu".
** If this value is omitted if there are no merge children.
** mu: The id of the row which is the top of the merge-out arrow.
** Only exists if "mo" exists.
** cu: Extend the mu merge arrow up to this row as a cherrypick
** merge line, if this value exists.
** u: Draw a thick child-line out of the top of this node and up to
** the node with an id equal to this value. 0 if it is straight to
** the top of the page, -1 if there is no thick-line riser.
** f: 0x01: a leaf node.
** au: An array of integers that define thick-line risers for branches.
** The integers are in pairs. For each pair, the first integer is
** is the rail on which the riser should run and the second integer
** is the id of the node upto which the riser should run. If there
** are no risers, this array does not exist.
** mi: "merge-in". An array of integer rail positions from which
** merge arrows should be drawn into this node. If the value is
** negative, then the rail position is -1-mi[] and a thin merge-arrow
** descender is drawn to the bottom of the screen. This array is
** omitted if there are no inbound merges.
** ci: "cherrypick-in". Like "mi" except for cherrypick merges.
** omitted if there are no cherrypick merges.
** h: The artifact hash of the object being graphed

*******************************************************************************
**
** This file contains the JS code used to implement the expanding hamburger
** menu on various skins.
**
** This was original the "js.txt" file for the default skin. It was subsequently
** moved into src/hbmenu.js so that it could be more easily reused by other skins
** using the "builtin_request_js" TH1 command.
**
** Operation:
**
** This script expects the HTML to contain two elements:
**
** <a id="hbbtn"> <--- The hamburger menu button
** <nav id="hbdrop"> <--- Container for the hamburger menu
**
** Bindings are made on hbbtn so that when it is clicked, the following
** happens:
**
** 1. An XHR is made to /sitemap?popup to fetch the HTML for the
** popup menu.
**
** 2. The HTML for the popup is inserted into hddrop.
**
** 3. The hddrop container is made visible.
**
** CSS rules are also needed to cause the hddrop to be initially invisible,
** and to correctly style and position the hddrop container.

**
** hook-last-rcvid The last rcvid for which post-receive hooks were
** run.
**
** hook-embargo Do not run hooks again before this julianday.
**
** For "after-receive" hooks, a list of the received artifacts is sent
** into the command via standard input. Each line of input begins with

** COMMAND: hook*
**
** Usage: %fossil hook COMMAND ...
**
** Commands include:
**
** > fossil hook add --command COMMAND --type TYPE --sequence NUMBER
**
** Create a new hook. The --command and --type arguments are
** required. --sequence is optional.
**
** > fossil hook delete ID ...
**
** Delete one or more hooks by their IDs. ID can be "all"
** to delete all hooks. Caution: There is no "undo" for
** this operation. Deleted hooks are permanently lost.
**
** > fossil hook edit --command COMMAND --type TYPE --sequence NUMBER ID ...
**
** Make changes to one or more existing hooks. The ID argument
** is either a hook-id, or a list of hook-ids, or the keyword
** "all". For example, to disable hook number 2, use:
**
** fossil hook edit --type disabled 2
**
** > fossil hook list
**
** Show all current hooks
**
** > fossil hook status
**
** Print the values of CONFIG table entries that are relevant to
** hook processing. Used for debugging.
**
** > fossil hook test [OPTIONS] ID
**
** Run the hook script given by ID for testing purposes.
** Options:
**
** --dry-run Print the script on stdout rather than run it
** --base-rcvid N Pretend that the hook-last-rcvid value is N
** --new-rcvid M Pretend that the last rcvid valud is M
** --aux-file NAME NAME is substituted for %A in the script
**
** The --base-rcvid and --new-rcvid options are silently ignored if
** the hook type is not "after-receive". The default values for
** --base-rcvid and --new-rcvid cause the last receive to be processed.

/* As an anti-robot defense, <a> elements are initially coded with the
** href= set to the honeypot, and <form> elements are initialized with
** action= set to the login page. The real values for href= and action=
** are held in data-href= and data-action=. The following code moves
** data-href= into href= and data-action= into action= for all
** <a> and <form> elements, after delay and maybe also after mouse
** movement is seen.
**
** Before sourcing this script, create a separate <script> element
** (with type='application/json' to avoid Content Security Policy issues)
** containing:
**
** {"delay":MILLISECONDS, "mouseover":BOOLEAN}
**
** The <script> must have an id='href-data'. DELAY is the number
** milliseconds delay prior to populating href= and action=. If the
** mouseover boolean is true, then the href= rewrite is further delayed
** until the first mousedown event that occurs after the timer expires.

/* Add an approprate PATH= argument to the SSH command under construction
** in pCmd.
**
** About This Feature
** ==================
**
** On some ssh servers (Macs in particular are guilty of this) the PATH
** variable in the shell that runs the command that is sent to the remote
** host contains a limited number of read-only system directories:
**
** /usr/bin:/bin:/usr/sbin:/sbin
**
** The fossil executable cannot be installed into any of those directories
** because they are locked down, and so the "fossil" command cannot run.
**
** To work around this, the fossil command is prefixed with the PATH=
** argument, inserted by this function, to augment the PATH with additional
** directories in which the fossil executable is often found.
**
** But other ssh servers are confused by this initial PATH= argument.
** Some ssh servers have a list of programs that they are allowed to run
** and will fail if the first argument is not on that list, and PATH=....
** is not on that list.
**
** So that various commands that use ssh can run seamlessly on a variety
** of systems (commands that use ssh include "fossil sync" with an ssh:
** URL and the "fossil patch pull" and "fossil patch push" commands where
** the destination directory starts with HOSTNAME: or USER@HOSTNAME:.)
** the following algorithm is used:
**
** * First try running the fossil without any PATH= argument. If that
** works (and it does on a majority of systems) then we are done.
**
** * If the first attempt fails, then try again after adding the
** PATH= prefix argument. (This function is what adds that
** argument.) If the retry works, then remember that fact using
** the use-path-for-ssh:HOSTNAME setting so that the first step
** is skipped on subsequent uses of the same command.
**
** See the forum thread at
** https://fossil-scm.org/forum/forumpost/4903cb4b691af7ce for more
** background.
**
** See also:
**
** * The ssh_needs_path_argument() function above.
** * The test-ssh-needs-path command that shows the settings
** that cache whether or not a PATH= is needed for a particular
** HOSTNAME.

/*
** COMMAND: import*
**
** Usage: %fossil import ?--git? ?OPTIONS? NEW-REPOSITORY ?INPUT-FILE?
** or: %fossil import --svn ?OPTIONS? NEW-REPOSITORY ?INPUT-FILE?
**
** Read interchange format generated by another VCS and use it to
** construct a new Fossil repository named by the NEW-REPOSITORY
** argument. If no input file is supplied the interchange format
** data is read from standard input.
**
** The following formats are currently understood by this command
**
** --git Import from the git-fast-export file format (default)
** Options:
** --import-marks FILE Restore marks table from FILE
** --export-marks FILE Save marks table to FILE
** --rename-master NAME Renames the master branch to NAME
** --use-author Uses author as the committer
** --attribute "EMAIL USER" Attribute commits to USER
** instead of Git committer EMAIL address
**
** --svn Import from the svnadmin-dump file format. The default
** behaviour (unless overridden by --flat) is to treat 3
** folders in the SVN root as special, following the
** common layout of SVN repositories. These are (by
** default) trunk/, branches/ and tags/. The SVN --deltas
** format is supported but not required.
** Options:
** --trunk FOLDER Name of trunk folder
** --branches FOLDER Name of branches folder
** --tags FOLDER Name of tags folder
** --base PATH Path to project root in repository
** --flat The whole dump is a single branch
** --rev-tags Tag each revision, implied by -i
** --no-rev-tags Disables tagging effect of -i
** --rename-rev PAT Rev tag names, default "svn-rev-%"
** --ignore-tree DIR Ignores subtree rooted at DIR
**
** Common Options:
** -i|--incremental Allow importing into an existing repository
** -f|--force Overwrite repository if already exists
** -q|--quiet Omit progress output
** --no-rebuild Skip the "rebuilding metadata" step
** --no-vacuum Skip the final VACUUM of the database file
** --rename-trunk NAME Use NAME as name of imported trunk branch
** --rename-branch PAT Rename all branch names using PAT pattern
** --rename-tag PAT Rename all tag names using PAT pattern
** -A|--admin-user NAME Use NAME for the admin user
**
** The --incremental option allows an existing repository to be extended
** with new content. The --rename-* options may be useful to avoid name
** conflicts when using the --incremental option. The --admin-user
** option is ignored if --incremental is specified.
**
** The argument to --rename-* contains one "%" character to be replaced
** with the original name. For example, "--rename-tag svn-%-tag" renames
** the tag called "release" to "svn-release-tag".
**
** --ignore-tree is useful for importing Subversion repositories which
** move branches to subdirectories of "branches/deleted" instead of
** deleting them. It can be supplied multiple times if necessary.
**
** The --attribute option takes a quoted string argument comprised of a
** Git committer email and the username to be attributed to corresponding
** check-ins in the Fossil repository. This option can be repeated. For
** example, --attribute "drh@sqlite.org drh" --attribute "xyz@abc.net X".
** Attributions are persisted to the repository so that subsequent
** 'fossil git export' operations attribute Fossil commits to corresponding
** 'Git Committer <git@committer.com>' users, and incremental imports with
** 'fossil import --git --incremental' use previous --attribute records.
**

** txt - Force display of unformatted source text

** If zTarget is an interwiki link, return a pointer to a URL for that
** link target in memory obtained from fossil_malloc(). If zTarget is
** not a valid interwiki link, return NULL.
**
** An interwiki link target is of the form:
**
** Code:PageName
**
** "Code" is a brief code that describes the intended target wiki.
** The code must be ASCII alpha-numeric. No symbols or non-ascii
** characters are allows. Case is ignored for the code.
** Codes are assigned by "intermap:*" entries in the CONFIG table.
** The link is only valid if there exists an entry in the CONFIG table
** that matches "intermap:Code".
**
** Each value of each intermap:Code entry in the CONFIG table is a JSON
** object with the following fields:
**
** {
** "base": Base URL for the remote site.
** "hash": Append this to "base" for Hash targets.
** "wiki": Append this to "base" for Wiki targets.
** }
**
** If the remote wiki is Fossil, then the correct value for "hash"
** is "/info/" and the correct value for "wiki" is "/wiki?name=".
** If (for example) Wikipedia is the remote, then "hash" should be
** omitted and the correct value for "wiki" is "/wiki/".
**
** PageName is link name of the target wiki. Several different forms
** of PageName are recognized.
**
** Path If PageName is empty or begins with a "/" character, then
** it is a pathname that is appended to "base".
**
** Hash If PageName is a hexadecimal string of 4 or more
** characters, then PageName is appended to "hash" which
** is then appended to "base".
**
** Wiki If PageName does not start with "/" and it is
** not a hexadecimal string of 4 or more characters, then
** PageName is appended to "wiki" and that combination is
** appended to "base".
**

FOSSIL_JSON_API_VERSION holds the date (YYYYMMDD) of the latest

version number to each response type, allowing very fine (too
fine?) granularity in compatibility change notification. The
version number could be included in part of the command dispatching

** b) generating a response payload (if applicable)
** c) Setting g.json's error state (if applicable). See json_set_err().

i don't really like the discrepancy in the format but this list
can get really long and (A) most tags don't have values, (B) i
don't want to bloat it more, and (C) cson_object_set() is O(N)
(N=current number of properties) because it uses an unsorted list
internally (for memory reasons), so this can slow down appreciably
on a long list. The culprit is really tkt- tags, as there is one
for each ticket (941 in the main fossil repo as of this writing).

*******************************************************************************
**
** This file contains code for generating the login and logout screens.
**
** Notes:
**
** There are four special-case user-ids: "anonymous", "nobody",
** "developer" and "reader".
**
** The capabilities of the nobody user are available to anyone,
** regardless of whether or not they are logged in. The capabilities
** of anonymous are only available after logging in, but the login
** screen displays the password for the anonymous login, so this
** should not prevent a human user from doing so. The capabilities
** of developer and reader are inherited by any user that has the
** "v" and "u" capabilities, respectively.
**
** The nobody user has capabilities that you want spiders to have.
** The anonymous user has capabilities that you want people without
** logins to have.
**
** Of course, a sophisticated spider could easily circumvent the
** anonymous login requirement and walk the website. But that is
** not really the point. The anonymous login keeps search-engine
** crawlers and site download tools like wget from walking change
** logs and downloading diffs of very version of the archive that
** has ever existed, and things like that.

** login group where REPO2 is a member, in which case the optional --name
** argument is not required; or (2) create a new login group between the

** REPO specified with -R, and REPO2, in which case the new group NAME is
** determined by the mandatory --name option. In both cases, the specified

** About Login Groups:
**
** A login-group is a set of repositories that share user credentials.
** If a user is logged into one member of the group, then that user can
** access any other group member as long as they have an entry in the USER
** table of that member. If a user changes their password using web
** interface, their password is also automatically changed in every other
** member of the login group.

** COMMAND: cgi*
**
** Usage: %fossil ?cgi? FILE
**
** This command causes Fossil to generate reply to a CGI request.
**
** The FILE argument is the name of a control file that provides Fossil
** with important information such as where to find its repository. In
** a typical CGI deployment, FILE is the name of the CGI script and will
** typically look something like this:
**
** #!/usr/bin/fossil
** repository: /home/somebody/project.db
**
** The command name, "cgi", may be omitted if the GATEWAY_INTERFACE
** environment variable is set to "CGI", which should always be the
** case for CGI scripts run by a webserver. Fossil ignores any lines
** that begin with "#".
**
** The following control lines are recognized:
**
** repository: PATH Name of the Fossil repository
**
** directory: PATH Name of a directory containing many Fossil
** repositories whose names all end with ".fossil".
** There should only be one of "repository:"
** or "directory:"
**
** notfound: URL When in "directory:" mode, redirect to
** URL if no suitable repository is found.
**
** repolist When in "directory:" mode, display a page
** showing a list of available repositories if
** the URL is "/".
**
** localauth Grant administrator privileges to connections
** from 127.0.0.1 or ::1.
**
** nossl Signal that no SSL connections are available.
**
** nocompress Do not compress HTTP replies.
**
** skin: LABEL Use the built-in skin called LABEL rather than
** the default, or the default if LABEL is empty.
** If there are no skins called LABEL then this
** line is a no-op.
**
** files: GLOBLIST GLOBLIST is a comma-separated list of GLOB
** patterns that specify files that can be
** returned verbatim. This feature allows Fossil
** to act as a web server returning static
** content.
**
** setenv: NAME VALUE Set environment variable NAME to VALUE. Or
** if VALUE is omitted, unset NAME.
**
** HOME: PATH Shorthand for "setenv: HOME PATH"
**
** cgi-debug: FILE Causing debugging information to be written
** into FILE.
**
** errorlog: FILE Warnings, errors, and panics written to FILE.
**
** timeout: SECONDS Do not run for longer than SECONDS. The default
** timeout is FOSSIL_DEFAULT_TIMEOUT (600) seconds.
**
** extroot: DIR Directory that is the root of the sub-CGI tree
** on the /ext page.
**
** redirect: REPO URL Extract the "name" query parameter and search
** REPO for a check-in or ticket that matches the
** value of "name", then redirect to URL. There
** can be multiple "redirect:" lines that are
** processed in order. If the REPO is "*", then
** an unconditional redirect to URL is taken.
**
** jsmode: VALUE Specifies the delivery mode for JavaScript
** files. See the help text for the --jsmode
** flag of the http command.
**
** mainmenu: FILE Override the mainmenu config setting with the
** contents of the given file.
**
** Most CGI files contain only a "repository:" line. It is uncommon to
** use any other option.
**
** The lines are processed in the order they are read, which is most
** significant for "errorlog:", which should be set before "repository:"
** so that any warnings from the database when opening the repository
** go to that log file.

** COMMAND: http*
**
** Usage: %fossil http ?REPOSITORY? ?OPTIONS?
**
** Handle a single HTTP request appearing on stdin. The resulting webpage
** is delivered on stdout. This method is used to launch an HTTP request
** handler from inetd, for example. The REPOSITORY argument is the name of
** the repository.
**
** If REPOSITORY is a directory that contains one or more repositories,
** either directly in REPOSITORY itself or in subdirectories, and
** with names of the form "*.fossil" then a prefix of the URL pathname
** selects from among the various repositories. If the pathname does
** not select a valid repository and the --notfound option is available,
** then the server redirects (HTTP code 302) to the URL of --notfound.
** When REPOSITORY is a directory, the pathname must contain only
** alphanumerics, "_", "/", "-" and "." and no "-" may occur after a "/"
** and every "." must be surrounded on both sides by alphanumerics or else
** a 404 error is returned. Static content files in the directory are
** returned if they match comma-separate GLOB pattern specified by --files
** and do not match "*.fossil*" and have a well-known suffix.
**
** Options:
** --acme Deliver files from the ".well-known" subdirectory
** --baseurl URL Base URL (useful with reverse proxies)
** --cert FILE Use TLS (HTTPS) encryption with the certificate (the
** fullchain.pem) taken from FILE.
** --chroot DIR Use directory for chroot instead of repository path.
** --ckout-alias N Treat URIs of the form /doc/N/... as if they were
** /doc/ckout/...
** --extroot DIR Document root for the /ext extension mechanism
** --files GLOB Comma-separate glob patterns for static file to serve
** --host NAME DNS Hostname of the server
** --https The HTTP request originated from https but has already
** been decoded by a reverse proxy. Hence, URLs created
** by Fossil should use "https:" rather than "http:".
** --in FILE Take input from FILE instead of standard input
** --ipaddr ADDR Assume the request comes from the given IP address
** --jsmode MODE Determine how JavaScript is delivered with pages.
** Mode can be one of:
** inline All JavaScript is inserted inline at
** one or more points in the HTML file.
** separate Separate HTTP requests are made for
** each JavaScript file.
** bundled Groups JavaScript files into one or
** more bundled requests which
** concatenate scripts together.
** Depending on the needs of any given page, inline
** and bundled modes might result in a single
** amalgamated script or several, but both approaches
** result in fewer HTTP requests than the separate mode.
** --localauth Connections from localhost are given "setup"
** privileges without having to log in
** --mainmenu FILE Override the mainmenu config setting with the contents
** of the given file
** --nocompress Do not compress HTTP replies
** --nodelay Omit backoffice processing if it would delay
** process exit
** --nojail Drop root privilege but do not enter the chroot jail
** --nossl Do not do http: to https: redirects, regardless of
** the redirect-to-https setting.
** --notfound URL Use URL as the "HTTP 404, object not found" page
** --out FILE Write the HTTP reply to FILE instead of to
** standard output
** --pkey FILE Read the private key used for TLS from FILE
** --repolist If REPOSITORY is directory, URL "/" lists all repos
** --scgi Interpret input as SCGI rather than HTTP
** --skin LABEL Use override skin LABEL. Use an empty string ("")
** to force use of the current local skin config.
** --th-trace Trace TH1 execution (for debugging purposes)
** --usepidkey Use saved encryption key from parent process. This is
** only necessary when using SEE on Windows or Linux.

** COMMAND: server*
** COMMAND: ui
**
** Usage: %fossil server ?OPTIONS? ?REPOSITORY?
** or: %fossil ui ?OPTIONS? ?REPOSITORY?
**
** Open a socket and begin listening and responding to HTTP requests on
** TCP port 8080, or on any other TCP port defined by the -P or
** --port option. The optional REPOSITORY argument is the name of the
** Fossil repository to be served. The REPOSITORY argument may be omitted
** if the working directory is within an open check-out, in which case the
** repository associated with that check-out is used.
**
** The "ui" command automatically starts a web browser after initializing
** the web server. The "ui" command also binds to 127.0.0.1 and so will
** only process HTTP traffic from the local machine.
**
** If REPOSITORY is a directory name which is the root of a
** check-out, then use the repository associated with that check-out.
** This only works for the "fossil ui" command, not the "fossil server"
** command.
**
** If REPOSITORY begins with a "HOST:" or "USER@HOST:" prefix, then
** the command is run on the remote host specified and the results are
** tunneled back to the local machine via SSH. This feature only works for
** the "fossil ui" command, not the "fossil server" command. The name of the
** fossil executable on the remote host is specified by the --fossilcmd
** option, or if there is no --fossilcmd, it first tries "fossil" and if it
** is not found in the default $PATH set by SSH on the remote, it then adds
** "$HOME/bin:/usr/local/bin:/opt/homebrew/bin" to the PATH and tries again to
** run "fossil".
**
** REPOSITORY may also be a directory (aka folder) that contains one or
** more repositories with names ending in ".fossil". In this case, a
** prefix of the URL pathname is used to search the directory for an
** appropriate repository. To thwart mischief, the pathname in the URL must
** contain only alphanumerics, "_", "/", "-", and ".", and no "-" may
** occur after "/", and every "." must be surrounded on both sides by
** alphanumerics. Any pathname that does not satisfy these constraints
** results in a 404 error. Files in REPOSITORY that match the comma-separated
** list of glob patterns given by --files and that have known suffixes
** such as ".txt" or ".html" or ".jpeg" and do not match the pattern
** "*.fossil*" will be served as static content. With the "ui" command,
** the REPOSITORY can only be a directory if the --notfound option is
** also present.
**
** For the special case REPOSITORY name of "/", the global configuration
** database is consulted for a list of all known repositories. The --repolist
** option is implied by this special case. The "fossil ui /" command is
** equivalent to "fossil all ui". To see all repositories owned by "user"
** on machine "remote" via ssh, run "fossil ui user@remote:/".
**
** By default, the "ui" command provides full administrative access without
** having to log in. This can be disabled by turning off the "localauth"
** setting. Automatic login for the "server" command is available if the
** --localauth option is present and the "localauth" setting is off and the
** connection is from localhost. The "ui" command also enables --repolist
** by default.
**
** Options:
** --acme Deliver files from the ".well-known" subdirectory
** --baseurl URL Use URL as the base (useful for reverse proxies)
** --cert FILE Use TLS (HTTPS) encryption with the certificate (the
** fullchain.pem) taken from FILE.
** --chroot DIR Use directory for chroot instead of repository path
** --ckout-alias NAME Treat URIs of the form /doc/NAME/... as if they were
** /doc/ckout/...
** --create Create a new REPOSITORY if it does not already exist
** --errorlog FILE Append HTTP error messages to FILE
** --extroot DIR Document root for the /ext extension mechanism
** --files GLOBLIST Comma-separated list of glob patterns for static files
** --fossilcmd PATH The pathname of the "fossil" executable on the remote
** system when REPOSITORY is remote.
** --localauth Enable automatic login for requests from localhost
** --localhost Listen on 127.0.0.1 only (always true for "ui")
** --https Indicates that the input is coming through a reverse
** proxy that has already translated HTTPS into HTTP.
** --jsmode MODE Determine how JavaScript is delivered with pages.
** Mode can be one of:
** inline All JavaScript is inserted inline at
** the end of the HTML file.
** separate Separate HTTP requests are made for
** each JavaScript file.
** bundled One single separate HTTP fetches all
** JavaScript concatenated together.
** Depending on the needs of any given page, inline
** and bundled modes might result in a single
** amalgamated script or several, but both approaches
** result in fewer HTTP requests than the separate mode.
** --mainmenu FILE Override the mainmenu config setting with the contents
** of the given file
** --max-latency N Do not let any single HTTP request run for more than N
** seconds (only works on unix)
** -B|--nobrowser Do not automatically launch a web-browser for the
** "fossil ui" command
** --nocompress Do not compress HTTP replies
** --nojail Drop root privileges but do not enter the chroot jail
** --nossl Do not force redirects to SSL even if the repository
** setting "redirect-to-https" requests it. This is set
** by default for the "ui" command.
** --notfound URL Redirect to URL if a page is not found.
** -p|--page PAGE Start "ui" on PAGE. ex: --page "timeline?y=ci"
** --pkey FILE Read the private key used for TLS from FILE
** -P|--port [IP:]PORT Listen on the given IP (optional) and port
** --repolist If REPOSITORY is dir, URL "/" lists repos
** --scgi Accept SCGI rather than HTTP
** --skin LABEL Use override skin LABEL, or the site's default skin if
** LABEL is an empty string.
** --socket-mode MODE File permissions to set for the unix socket created
** by the --socket-name option.
** --socket-name NAME Use a unix-domain socket called NAME instead of a
** TCP/IP socket.
** --socket-owner USR Try to set the owner of the unix socket to USR.
** USR can be of the form USER:GROUP to set both
** user and group.
** --th-trace Trace TH1 execution (for debugging purposes)
** --usepidkey Use saved encryption key from parent process. This is

# Markdown Overview #
## Paragraphs ##
> Paragraphs are divided by blank lines.
> End a line with two or more spaces to force a mid-paragraph line break.
## Headings ##
>
# Top Level Heading Alternative Top Level Heading
# Top Level Heading Variant # =============================
>
## 2nd Level Heading Alternative 2nd Level Heading
## 2nd Level Heading Variant ## -----------------------------
>
### 3rd Level Heading ### 3rd Level Heading Variant ###
#### 4th Level Heading #### 4th Level Heading Variant ####
##### 5th Level Heading ##### 5th Level Heading Variant #####
###### 6th Level Heading ###### 6th Level Heading Variant ######
## Links ##
> 1. **\[display text\]\(URL\)**
> 2. **\[display text\]\(URL "Title"\)**
> 3. **\[display text\]\(URL 'Title'\)**
> 4. **\<URL\>**
> 5. **\[display text\]\[label\]**
> 6. **\[display text\]\[\]**
> 7. **\[display text\]**
> 8. **\[\]\(URL\)**
> With link formats 5, 6, and 7 ("reference links"), the URL is supplied
> elsewhere in the document, as shown below. Link formats 6 and 7 reuse
> the display text as the label. Labels are case-insensitive. The title
> may be split onto the next line with optional indenting.
> * **\[label\]: URL**
> * **\[label\]: URL "Title"**
> * **\[label\]: URL 'Title'**
> * **\[label\]: URL (Title)**
> If **URL** begins with "http:", "https:', "ftp:' or "mailto:",
> it may optionally be written **\<URL\>** (format 4).
> Other **URL** formats include:
> <ul>
> <li> A relative pathname.
> <li> A pathname starting with "/" in which case the Fossil server
> URL prefix is prepended
> <li> A wiki page name, or a wiki page name preceded by "wiki:"
> <li> An artifact or ticket hash or hash prefix
> <li> A date and time stamp: "YYYY-MM-DD HH:MM:SS" or a subset that
> includes at least the day of the month.
> <li> An [interwiki link](#intermap) of the form "<i>Tag</i><b>:</b><i>PageName</i>"</ul>
> In format 8, then the URL becomes the display text. This is useful for
> hyperlinks that refer to wiki pages and check-in and ticket hashes.
## Text Style ##
> * _\*italic\*_
> * *\_italic\_*
> * __\*\*bold\*\*__
> * **\_\_bold\_\_**
> * ___\*\*\*italic+bold\*\*\*___
> * ***\_\_\_italic+bold\_\_\_***
> * \``code`\`
> The **\`code\`** construct disables HTML markup, so one can write, for
> example, **\`\<html\>\`** to yield **`<html>`**.
## Lists ##
> ~~~
* bullet item
+ bullet item
- bullet item
1. numbered item
2) numbered item
~~~
> A two-level list is created by placing additional whitespace before the
> **\***/**+**/**-**/**1.** of the secondary items.
> ~~~
* top-level item
* second-level item
~~~
## Block Quotes ##
> Begin each line of a paragraph with **>** to block quote that paragraph.
> >
> This paragraph is indented
> >
> > Double-indented paragraph
## Literal/Verbatim Text - Code Blocks ##
> For inline text, you can either use \``backticks`\` or the HTML
> `<code>` tag.
>
> For blocks of text or code:
>
> 1. Indent the text using a tab character or at least four spaces.
> 2. Precede the block with an HTML `<pre>` tag and follow it with `</pre>`.
> 3. Surround the block by <tt>\`\`\`</tt> (three or more) or <tt>\~\~\~</tt> either at the
> left margin or indented no more than three spaces. The first word
> on that same line (if any) is used in a “`language-WORD`†CSS style in
> the HTML rendering of that code block and is intended for use by
> code syntax highlighters. Thus <tt>\`\`\`c</tt> would mark a block of code
> in the C programming language. Text to be rendered inside the code block
> should therefore start on the next line, not be cuddled up with the
> backticks or tildes. See the "Diagrams" section below for the case where
> "`language-WORD`" is "pikchr".
> With the standard skins, verbatim text is rendered in a fixed-width font,
> but that is purely a presentation matter, controlled by the skin’s CSS.
## Tables ##
>
| Header 1 | Header 2 | Header 3 |
----------------------------------------------
| Row 1 Col 1 | Row 1 Col 2 | Row 1 Col 3 |
|:Left-aligned |:Centered :| Right-aligned:|
| | ↠Blank → | |
| Row 4 Col 1 | Row 4 Col 2 | Row 4 Col 3 |
> The first row is a header if followed by a horizontal rule or a blank line.
> Placing **:** at the left, both, or right sides of a cell gives left-aligned,
> centered, or right-aligned text, respectively. By default, both header and
> body cells are left-aligned.
> The leftmost or rightmost **\|** is required only if the first or last column,
> respectively, contains at least one blank cell.

## Footnotes ##
> Footnotes (or "endnotes") is a Fossil extension of classical Markdown.
> Fossil's syntax for footnotes is similar to links and
> is distinguished by the use of character **^**
> that *immediately* follows an opening bracket.
> 1. **\(^** footnote's text **)**
> 2. **\[** fragment of text **]\(^** a comment about that fragment **\)**
> 3. **\[^** label **\]**
> 4. **\[** fragment of text **\]\[^** label **\]**
> 5. **\[** fragment of text **\]\[^\]**
> With formats 1 and 2 ("inline footnotes") text of a footnote is provided
> in the place where the corresponding numeric mark will be rendered.
> With formats 3, 4, and 5 ("reference footnotes") text of a footnote
> is supplied elsewhere in the document, as shown below.
> Formats 2, 4 and 5 ("span-specific footnotes") mark a specific fragment
> that is being commented in the footnote.
> Format 5 reuses a fragment of text as a label.
> Labels are case-insensitive.
> ```
> [^label]: Footnote definition must start on the first column.
> The second line (if any) must be indented by two or more spaces.
> Definition continues until indentation drops below that of the 2nd line.
>```
> Character **^** is not part of a label, it is part of the syntax.
> Both a footnote's text and a fragment to which a footnote applies
> are subject to further interpretation as Markdown sources.
## Miscellaneous ##
> * In-line images are made using **\!\[alt-text\]\(image-URL\)**.
> * Use HTML for advanced formatting such as forms, noting that certain
> tags are [disallowed in some contexts](/help?cmd=safe-html).
> * **\<!--** HTML-style comments **-->** are supported.
> * Escape special characters (ex: **\[** **\(** **\|** **\***)
> using backslash (ex: **\\\[** **\\\(** **\\\|** **\\\***).
> * A line consisting of **---**, **\*\*\***, or **\_\_\_** is a horizontal
> rule. Spaces and extra **-**/**\***/**_** are allowed.
> * Paragraphs enclosed in **\<html\>...\</html\>** is passed through unchanged.
> * See [daringfireball.net][] for additional information.
> * See this page's [Markdown source](/md_rules?txt=1) for more examples.
## Special Features For Fossil ##
> * In hyperlinks, if the URL begins with **/** then the root of the Fossil
> repository is prepended. This allows for repository-relative hyperlinks.
> * For documents that begin with a top-level heading (ex: **# heading #**),
> the heading is omitted from the body of the document and becomes the
> document title displayed at the top of the Fossil page.

** COMMAND: merge
** COMMAND: cherry-pick alias
** COMMAND: cherrypick
**
** Usage: %fossil merge ?OPTIONS? ?VERSION ...?
** Or: %fossil cherrypick ?OPTIONS? ?VERSION ...?
**
** The argument VERSION is a version that should be merged into the
** current check-out. All changes from VERSION back to the nearest
** common ancestor are merged. Except, if either of the --cherrypick
** or --backout options are used only the changes associated with the
** single check-in VERSION are merged. The --backout option causes
** the changes associated with VERSION to be removed from the current
** check-out rather than added. When invoked with the name
** "cherrypick" instead of "merge", this command works exactly like
** "merge --cherrypick".
**
** Files which are renamed in the merged-in branch will be renamed in
** the current check-out.
**
** If the VERSION argument is omitted, then Fossil attempts to find
** a recent fork on the current branch to merge.
**
** If there are multiple VERSION arguments, then each VERSION is merged
** (or cherrypicked) in the order that they appear on the command-line.
**
** Options:
** --backout Do a reverse cherrypick merge against VERSION.
** In other words, back out the changes that were
** added by VERSION.
** --baseline BASELINE Use BASELINE as the "pivot" of the merge instead
** of the nearest common ancestor. This allows
** a sequence of changes in a branch to be merged
** without having to merge the entire branch.

** COMMAND: 3-way-merge*
**
** Usage: %fossil 3-way-merge BASELINE V1 V2 MERGED
**
** Inputs are files BASELINE, V1, and V2. The file MERGED is generated
** as output.
**
** BASELINE is a common ancestor of two files V1 and V2 that have diverging
** edits. The generated output file MERGED is the combination of all
** changes in both V1 and V2.
**
** This command has no effect on the Fossil repository. It is a utility
** command made available for the convenience of users. This command can
** be used, for example, to help import changes from an upstream project.
**
** Suppose an upstream project has a file named "Xup.c" which is imported
** with modifications to the local project as "Xlocal.c". Suppose further
** that the "Xbase.c" is an exact copy of the last imported "Xup.c".
** Then to import the latest "Xup.c" while preserving all the local changes:
**
** fossil 3-way-merge Xbase.c Xlocal.c Xup.c Xlocal.c
** cp Xup.c Xbase.c
** # Verify that everything still works
** fossil commit

** * "date:" + Date or date-time
** * symbolic-name ":" date-time

**
** The following additional forms are available in local checkouts:
**
** * "current"
** * "prev" or "previous"
** * "next"
**
** The following modifier prefixes may be applied to the above forms:
**
** * "root:BR" = The origin of the branch named BR.
** * "start:BR" = The first check-in of the branch named BR.
** * "merge-in:BR" = The most recent merge-in for the branch named BR.
**
** In those forms, BR may be any symbolic form but is assumed to be a

** in a branch and possibly in the trunk, but never a wiki edit or
** forum post.
**

** match any known object. Or return -1 if the name is ambiguous.

** If zType is NULL or "" or "*" then any type of artifact will serve.
** If zType is "br" then find the first check-in of the named branch
** rather than the last.
**
** zType is "ci" in most use cases since we are usually searching for
** a check-in. A value of "ci+" works like "ci" but adds these
** semantics: if zTag is "ckout" and a checkout is open, "ci+" causes
** RID_CKOUT to be returned, in which case g.localOpen will hold the
** RID of the checkout. Conversely, passing in the hash, or another
** symbolic name of the local checkout version, will always result in
** its RID being returned.
**
** Note that the input zTag for types "t" and "e" is the artifact hash of
** the ticket-change or technote-change artifact, not the randomly generated
** hexadecimal identifier assigned to tickets and events. Those identifiers

** COMMAND: patch
**
** Usage: %fossil patch SUBCOMMAND ?ARGS ..?
**
** This command is used to create, view, and apply Fossil binary patches.
** A Fossil binary patch is a single (binary) file that captures all of the
** uncommitted changes of a check-out. Use Fossil binary patches to transfer
** proposed or incomplete changes between machines for testing or analysis.
**
** > fossil patch create [DIRECTORY] PATCHFILE
**
** Create a new binary patch in PATCHFILE that captures all uncommitted
** changes in the check-out at DIRECTORY, or the current directory if
** DIRECTORY is omitted. If PATCHFILE is "-" then the binary patch
** is written to standard output.
**
** Options:
** -f|--force Overwrite an existing patch with the same name
**
** > fossil patch apply [DIRECTORY] PATCHFILE
**
** Apply the changes in PATCHFILE to the check-out at DIRECTORY, or
** in the current directory if DIRECTORY is omitted.
**
** Options:
** -f|--force Apply the patch even though there are unsaved
** changes in the current check-out. Unsaved changes
** are reverted and permanently lost.
** -n|--dry-run Do nothing, but print what would have happened
** -v|--verbose Extra output explaining what happens
**
** > fossil patch diff [DIRECTORY] PATCHFILE
** > fossil patch gdiff [DIRECTORY] PATCHFILE
**
** Show a human-readable diff for the patch in PATCHFILE and associated
** with the repository checked out in DIRECTORY. The current
** directory is used if DIRECTORY is omitted. All the usual
** diff flags described at "fossil help diff" apply. With gdiff,
** gdiff-command is used instead of internal diff logic. In addition:
**
** -f|--force Continue trying to perform the diff even if
** baseline information is missing from the current
** repository
**
** > fossil patch push REMOTE-CHECKOUT
**
** Create a patch for the current check-out, transfer that patch to
** a remote machine (using ssh) and apply the patch there. The
** REMOTE-CHECKOUT is in one of the following formats:
**
** * DIRECTORY
** * HOST:DIRECTORY
** * USER@HOST:DIRECTORY
**
** The name of the fossil executable on the remote host is specified
** by the --fossilcmd option, or if there is no --fossilcmd, it first
** tries "$HOME/bin/fossil" and if not found there it searches for any
** executable named "fossil" on the default $PATH set by SSH on the
** remote.
**
** Command-line options:
**
** -f|--force Apply the patch even though there are unsaved
** changes in the current check-out. Unsaved
** changes will be reverted and then the patch is
** applied.
** --fossilcmd EXE Name of the "fossil" executable on the remote
** -n|--dry-run Do nothing, but print what would have happened
** -v|--verbose Extra output explaining what happens
**
**
** > fossil patch pull REMOTE-CHECKOUT
**
** Like "fossil patch push" except that the transfer is from remote
** to local. All the same command-line options apply.
**
** > fossil patch view PATCHFILE
**
** View a summary of the changes in the binary patch in PATCHFILE.
** Use "fossil patch diff" for detailed patch content.
**
** -v|--verbose Show extra detail about the patch
**

** Processes a pikchr script, optionally with embedded TH1, and
** produces HTML code for it. zIn is the NUL-terminated input
** script. pikFlags may be a bitmask of any of the PIKCHR_PROCESS_xxx
** flags documented below. thFlags may be a bitmask of any of the
** TH_INIT_xxx and/or TH_R2B_xxx flags. Output is sent to pOut,
** appending to it without modifying any prior contents.
**
** Returns 0 on success, 1 if TH1 processing failed, or 2 if pikchr
** processing failed. In either case, the error message (if any) from
** TH1 or pikchr will be appended to pOut.
**
** pikFlags flag descriptions:
**
** - PIKCHR_PROCESS_TH1 means to run zIn through TH1, using the TH1
** init flags specified in the 3rd argument. If thFlags is non-0 then
** this flag is assumed even if it is not specified.
**
** - PIKCHR_PROCESS_TH1_NOSVG means that processing stops after the
** TH1 eval step, thus the output will be (presumably) a
** TH1-generated/processed pikchr script (or whatever else the TH1
** outputs). If this flag is set, PIKCHR_PROCESS_TH1 is assumed even
** if it is not specified.
**
** All of the remaining flags listed below are ignored if
** PIKCHR_PROCESS_TH1_NOSVG is specified!
**
** - PIKCHR_PROCESS_DIV: if set, the SVG result is wrapped in a DIV
** element which specifies a max-width style value based on the SVG's
** calculated size. This flag has multiple mutually exclusive forms:
**
** - PIKCHR_PROCESS_DIV uses default element alignment.
** - PIKCHR_PROCESS_DIV_INDENT indents the div.
** - PIKCHR_PROCESS_DIV_CENTER centers the div.
** - PIKCHR_PROCESS_DIV_FLOAT_LEFT floats the div left.
** - PIKCHR_PROCESS_DIV_FLOAT_RIGHT floats the div right.
**
** If more than one is specified, which one is used is undefined. Those
** flags may be OR'd with one or both of the following:
**
** - PIKCHR_PROCESS_DIV_TOGGLE: adds the 'toggle' CSS class to the
** outer DIV so that event-handler code can install different
** toggling behaviour than the default. Default is ctrl-click, but
** this flag enables single-click toggling for the element.
**
** - PIKCHR_PROCESS_DIV_SOURCE: adds the 'source' CSS class to the
** outer DIV, which is a hint to the client-side renderer (see
** fossil.pikchr.js) that the pikchr should initially be rendered
** in source code form mode (the default is to hide the source and
** show the SVG).
**
** - PIKCHR_PROCESS_DIV_SOURCE_INLINE: adds the 'source-inline' CSS
** class to the outer wrapper. This modifier changes how the
** 'source' CSS class gets applied: with this flag, the source view
** should be rendered "inline" (same position as the graphic), else
** it is to be left-aligned.
**
** - PIKCHR_PROCESS_NONCE: if set, the resulting SVG/DIV are wrapped
** in "safe nonce" comments, which are a fossil-internal mechanism
** which prevents the wiki/markdown processors from re-processing this
** output. This is necessary when calling this routine in the context
** of wiki/embedded doc processing, but not (e.g.) when fetching
** an image for /pikchrpage.
**
** - PIKCHR_PROCESS_SRC: if set, a new PRE.pikchr-src element is
** injected adjacent to the SVG element which contains the
** HTML-escaped content of the input script. If
** PIKCHR_PROCESS_DIV_SOURCE or PIKCHR_PROCESS_DIV_SOURCE_INLINE is
** set, this flag is automatically implied.
**
** - PIKCHR_PROCESS_ERR_PRE: if set and pikchr() fails, the resulting
** error report is wrapped in a PRE element, else it is retained
** as-is (intended only for console output).

/*
** COMMAND: pikchr*
**
** Usage: %fossil pikchr [options] ?INFILE? ?OUTFILE?
**
** Accepts a pikchr script as input and outputs the rendered script as
** an SVG graphic. The INFILE and OUTFILE options default to stdin
** resp. stdout, and the names "-" can be used as aliases for those
** streams.
**
** Options:
** -div On success, add a DIV wrapper around the
** resulting SVG output which limits its max-width to
** its computed maximum ideal size
**
** -div-indent Like -div but indent the div
**
** -div-center Like -div but center the div
**
** -div-left Like -div but float the div left
**
** -div-right Like -div but float the div right
**
** -div-toggle Set the 'toggle' CSS class on the div (used by the
** JavaScript-side post-processor)
**
** -div-source Set the 'source' CSS class on the div, which tells
** CSS to hide the SVG and reveal the source by default.
**
** -src Store the input pikchr's source code in the output as
** a separate element adjacent to the SVG one. Implied
** by -div-source.
**
**
** -th Process the input using TH1 before passing it to pikchr
**
** -th-novar Disable $var and $<var> TH1 processing. Use this if the
** pikchr script uses '$' for its own purposes and that
** causes issues. This only affects parsing of '$' outside
** of TH1 script blocks. Code in such blocks is unaffected.
**
** -th-nosvg When using -th, output the post-TH1'd script
** instead of the pikchr-rendered output
**
** -th-trace Trace TH1 execution (for debugging purposes)
**
** -dark Change pikchr colors to assume a dark-mode theme.
**
**
** The -div-indent/center/left/right flags may not be combined.
**
** TH1-related Notes and Caveats:
**
** If the -th flag is used, this command must open a fossil database
** for certain functionality to work (via a check-out or the -R REPO
** flag). If opening a db fails, execution will continue but any TH1
** commands which require a db will trigger a fatal error.
**
** In Fossil skins, TH1 variables in the form $varName are expanded
** as-is and those in the form $<varName> are htmlized in the
** resulting output. This processor disables the htmlizing step, so $x
** and $<x> are equivalent unless the TH1-processed pikchr script
** invokes the TH1 command [enable_htmlify 1] to enable it. Normally
** that option will interfere with pikchr output, however, e.g. by
** HTML-encoding double-quotes.
**
** Many of the fossil-installed TH1 functions simply do not make any
** sense for pikchr scripts.

** ends execution with a SIGABRT signal, bypassing atexit processing.
** This signal can also produce a core dump on POSIX platforms.

** COMMAND: purge*
**
** The purge command removes content from a repository and stores that content
** in a "graveyard". The graveyard exists so that content can be recovered
** using the "fossil purge undo" command. The "fossil purge obliterate"
** command empties the graveyard, making the content unrecoverable.
**
** WARNING: This command can potentially destroy historical data and
** leave your repository in a goofy state. Know what you are doing!
** Make a backup of your repository before using this command!
**
** FURTHER WARNING: This command is a work-in-progress and may yet
** contain bugs.
**
** > fossil purge artifacts HASH... ?OPTIONS?
**
** Move arbitrary artifacts identified by the HASH list into the
** graveyard.
**
** > fossil purge cat HASH...
**
** Write the content of one or more artifacts in the graveyard onto
** standard output.
**
** > fossil purge checkins TAGS... ?OPTIONS?
**
** Move the check-ins or branches identified by TAGS and all of
** their descendants out of the repository and into the graveyard.
** If TAGS includes a branch name then it means all the check-ins
** on the most recent occurrence of that branch.
**
** > fossil purge files NAME ... ?OPTIONS?
**
** Move all instances of files called NAME into the graveyard.
** NAME should be the name of the file relative to the root of the
** repository. If NAME is a directory, then all files within that
** directory are moved.
**
** > fossil purge list|ls ?-l?
**
** Show the graveyard of prior purges. The -l option gives more
** detail in the output.
**
** > fossil purge obliterate ID... ?--force?
**
** Remove one or more purge events from the graveyard. Once a purge
** event is obliterated, it can no longer be undone. The --force
** option suppresses the confirmation prompt.
**
** > fossil purge tickets NAME ... ?OPTIONS?
**
** TBD...
**
** > fossil purge undo ID
**
** Restore the content previously removed by purge ID.
**
** > fossil purge wiki NAME ... ?OPTIONS?
**
** TBD...
**
** COMMON OPTIONS:
**
** --explain Make no changes, but show what would happen
** --dry-run An alias for --explain

** COMMAND: deconstruct*
**
** Usage %fossil deconstruct ?OPTIONS? DESTINATION
**
** This command exports all artifacts of a given repository and writes all
** artifacts to the file system. The DESTINATION directory will be populated
** with subdirectories AA and files AA/BBBBBBBBB.., where AABBBBBBBBB.. is the
** 40+ character artifact ID, AA the first 2 characters.
** If -L|--prefixlength is given, the length (default 2) of the directory prefix
** can be set to 0,1,..,9 characters.
**
** Options:
** -R|--repository REPO Deconstruct given REPOSITORY
** -K|--keep-rid1 Save the filename of the artifact with RID=1 to
** the file .rid1 in the DESTINATION directory
** -L|--prefixlength N Set the length of the names of the DESTINATION
** subdirectories to N
** --private Include private artifacts
** -P|--keep-private Save the list of private artifacts to the file
** .private in the DESTINATION directory (implies
** the --private option)

******************************************************************************
**
** This file was adapted from the ext/misc/regexp.c file in SQLite3. That
** file is in the public domain.
**
** See ../www/grep.md for details of the algorithm and RE dialect.
**
**
** The following regular expression syntax is supported:
**
** X* zero or more occurrences of X
** X+ one or more occurrences of X
** X? zero or one occurrences of X
** X{p,q} between p and q occurrences of X
** (X) match X
** X|Y X or Y
** ^X X occurring at the beginning of the string
** X$ X occurring at the end of the string
** . Match any single character
** \c Character c where c is one of \{}()[]|*+?.
** \c C-language escapes for c in afnrtv. ex: \t or \n
** \uXXXX Where XXXX is exactly 4 hex digits, unicode value XXXX
** \xXX Where XX is exactly 2 hex digits, unicode value XX
** [abc] Any single character from the set abc
** [^abc] Any single character not in the set abc
** [a-z] Any single character in the range a-z
** [^a-z] Any single character not in the range a-z
** \b Word boundary
** \w Word character. [A-Za-z0-9_]
** \W Non-word character
** \d Digit
** \D Non-digit
** \s Whitespace character
** \S Non-whitespace character
**
** A nondeterministic finite automaton (NFA) is used for matching, so the
** performance is bounded by O(N*M) where N is the size of the regular
** expression and M is the size of the input string. The matcher never
** exhibits exponential behavior. Note that the X{p,q} operator expands
** to p copies of X following by q-p copies of X? and that the size of the
** regular expression in the O(N*M) performance bound is computed after
** this expansion.

** -i|--ignore-case Ignore case
** -l|--files-with-matches List only hash for each match
** --once Stop searching after the first match
** -s|--no-messages Suppress error messages about nonexistent

@ <h3>Notes</h3>
@ <ul>
@ <li><p>The SQL must consist of a single SELECT statement</p></li>
@
@ <li><p>If a column of the result set is named "#" then that column
@ is assumed to hold a ticket number. A hyperlink will be created from
@ that column to a detailed view of the ticket.</p></li>
@
@ <li><p>If a column of the result set is named "bgcolor" then the content
@ of that column determines the background color of the row.</p></li>
@
@ <li><p>The text of all columns prior to the first column whose name begins
@ with underscore ("_") is shown character-for-character as it appears in
@ the database. In other words, it is assumed to have a mimetype of
@ text/plain.
@
@ <li><p>The first column whose name begins with underscore ("_") and all
@ subsequent columns are shown on their own rows in the table and with
@ wiki formatting. In other words, such rows are shown with a mimetype
@ of text/x-fossil-wiki. This is recommended for the "description" field
@ of tickets.
@ </p></li>
@
@ <li><p>The query can join other tables in the database besides TICKET.
@ </p></li>
@ </ul>
@
@ <h3>Examples</h3>
@ <p>In this example, the first column in the result set is named
@ "bgcolor". The value of this column is not displayed. Instead, it
@ selects the background color of each row based on the TICKET.STATUS
@ field of the database. The color key at the right shows the various
@ color codes.</p>

**
** Options:
** -type|y FLAG May be: all (default), ci (show check-ins only),
** t (show tickets only), w (show wiki only)
**
** -limit|n LIMIT The maximum number of items to show
**
** -tkt HASH Filter for only those events for the specified ticket
**
** -tag TAG Filter for a tag
**
** -wiki NAME Filter on a specific wiki page
**
** Only one of -tkt, -tag, or -wiki may be used.
**
** -name FILENAME Filter for a specific file. This may be combined
** with one of the other filters (useful for looking

*******************************************************************************

** This file contains code to implement a search functions

**
** The search can be either a per-query "grep"-like search that scans
** the entire corpus. Or it can use the FTS4 search engine of SQLite.
** The choice is an administrator configuration option.
**
** The first option is referred to as "full-scan search". The second
** option is called "indexed search".

** The code in this file is ordered approximately as follows:

** (1) The full-scan search engine
** (2) The indexed search engine
** (3) Higher level interfaces that use either (1) or (b2) according

/*
** COMMAND: fts-config*
**
** Usage: fossil fts-config ?SUBCOMMAND? ?ARGUMENT?
**
** The "fossil fts-config" command configures the full-text search capabilities
** of the repository. Subcommands:
**
** reindex Rebuild the search index. This is a no-op if
** index search is disabled
**
** index (on|off) Turn the search index on or off
**
** enable cdtwef Enable various kinds of search. c=Check-ins,
** d=Documents, t=Tickets, w=Wiki, e=Tech Notes,
** f=Forum.
**
** disable cdtwef Disable various kinds of search
**
** tokenizer VALUE Select a tokenizer for indexed search. VALUE
** may be one of (porter, on, off, trigram, unicode61),
** and "on" is equivalent to "porter". Unindexed
** search never uses tokenization or stemming.
**
** The current search settings are displayed after any changes are applied.
** Run this command with no arguments to simply see the settings.

@ <p>Enable hyperlinks (the equivalent of the "h" permission) for all users,
@ including user "nobody", as long as the User-Agent string in the
@ HTTP header indicates that the request is coming from an actual human
@ being. If this setting is "UserAgent only" (2) then the
@ UserAgent string is the only factor considered. If the value of this
@ setting is "UserAgent And Javascript" (1) then Javascript is added that
@ runs after the page loads and fills in the href= values of <a>
@ elements. In either case, <a> tags are only generated if the
@ UserAgent string indicates that the request is coming from a human and
@ not a robot.
@
@ <p>This setting is designed to give easy access to humans while
@ keeping out robots.
@ You do not normally want a robot to walk your entire repository because
@ if it does, your server will end up computing diffs and annotations for
@ every historical version of every file and creating ZIPs and tarballs of
@ every historical check-in, which can use a lot of CPU and bandwidth
@ even for relatively small projects.</p>
@
@ <p>The "UserAgent and Javascript" value for this setting provides
@ superior protection from robots. However, that setting also prevents
@ the visited/unvisited colors on hyperlinks from displaying correctly
@ on Safari-derived browsers. (Chrome and Firefox work fine.) Since
@ Safari is the underlying rendering engine on all iPhones and iPads,
@ this means that hyperlink visited/unvisited colors will not operate
@ on those platforms when "UserAgent and Javascript" is selected.</p>
@
@ <p>Additional parameters that control the behavior of Javascript:</p>
@ <blockquote>
entry_attribute("Delay in milliseconds before enabling hyperlinks", 5,
"auto-hyperlink-delay", "ah-delay", "50", 0);
@ <br>
onoff_attribute("Also require a mouse event before enabling hyperlinks",
"auto-hyperlink-mouseover", "ahmo", 0, 0);
@ </blockquote>
@ <p>For maximum robot defense, "Delay" should be at least 50 milliseconds
@ and "require a mouse event" should be turned on. These values only come
@ into play when the main auto-hyperlink settings is 2 ("UserAgent and
@ Javascript").</p>
@
@ <p>To see if Javascript-base hyperlink enabling mechanism is working,
@ visit the <a href="%R/test_env">/test_env</a> page (from a separate
@ web browser that is not logged in, even as "anonymous") and verify
@ that the "g.jsHref" value is "1".</p>

@ <hr>
@ <p>When the first term of an incoming URL exactly matches one of
@ the "Aliases" on the left-hand side (LHS) above, the URL is
@ converted into the corresponding form on the right-hand side (RHS).
@ <ul>
@ <li><p>
@ The LHS is compared against only the first term of the incoming URL.
@ All LHS entries in the alias table should therefore begin with a
@ single "/" followed by a single path element.
@ <li><p>
@ The RHS entries in the alias table should begin with a single "/"
@ followed by a path element, and optionally followed by "?" and a
@ list of query parameters.
@ <li><p>
@ Query parameters on the RHS are added to the set of query parameters
@ in the incoming URL.
@ <li><p>
@ If the same query parameter appears in both the incoming URL and
@ on the RHS of the alias, the RHS query parameter value overwrites
@ the value on the incoming URL.
@ <li><p>
@ If a query parameter on the RHS of the alias is of the form "X!"
@ (a name followed by "!") then the X query parameter is removed
@ from the incoming URL if
@ it exists.
@ <li><p>
@ Only a single alias operation occurs. It is not possible to nest aliases.
@ The RHS entries must be built-in webpage names.
@ <li><p>
@ The alias table is only checked if no built-in webpage matches
@ the incoming URL.
@ Hence, it is not possible to override a built-in webpage using aliases.
@ This is by design.
@ </ul>
@
@ <p>To delete an entry from the alias table, change its name or value to an
@ empty string and press "Apply Changes".
@
@ <p>To add a new alias, fill in the name and value in the bottom row
@ of the table above and press "Apply Changes".

@ privilege.
@ </p></li>
@
@ <li><p>
@ The <span class="capability">Delete</span> privilege give the user the
@ ability to erase wiki, tickets, and attachments that have been added
@ by anonymous users. This capability is intended for deletion of spam.
@ The delete capability is only in effect for 24 hours after the item
@ is first posted. The <span class="usertype">Setup</span> user can
@ delete anything at any time.
@ </p></li>
@
@ <li><p>
@ The <span class="capability">Hyperlinks</span> privilege allows a user
@ to see most hyperlinks. This is recommended ON for most logged-in users
@ but OFF for user "nobody" to avoid problems with spiders trying to walk
@ every diff and annotation of every historical check-in and file.
@ </p></li>
@
@ <li><p>
@ The <span class="capability">Zip</span> privilege allows a user to
@ see the "download as ZIP"
@ hyperlink and permits access to the <tt>/zip</tt> page. This allows
@ users to download ZIP archives without granting other rights like
@ <span class="capability">Read</span> or
@ <span class="capability">Hyperlink</span>. The "z" privilege is recommended
@ for user <span class="usertype">nobody</span> so that automatic package
@ downloaders can obtain the sources without going through the login

@
@ <h2>Special Logins</h2>
@
@ <ul>
@ <li><p>
@ No login is required for user <span class="usertype">nobody</span>. The
@ capabilities of the <span class="usertype">nobody</span> user are
@ inherited by all users, regardless of whether or not they are logged in.
@ To disable universal access to the repository, make sure that the
@ <span class="usertype">nobody</span> user has no capabilities
@ enabled. The password for <span class="usertype">nobody</span> is ignored.
@ </p></li>
@
@ <li><p>
@ Login is required for user <span class="usertype">anonymous</span> but the
@ password is displayed on the login screen beside the password entry box
@ so anybody who can read should be able to login as anonymous.
@ On the other hand, spiders and web-crawlers will typically not
@ be able to login. Set the capabilities of the
@ <span class="usertype">anonymous</span>
@ user to things that you want any human to be able to do, but not any
@ spider. Every other logged-in user inherits the privileges of
@ <span class="usertype">anonymous</span>.
@ </p></li>
@
@ <li><p>
@ The <span class="usertype">developer</span> user is intended as a template
@ for trusted users with check-in privileges. When adding new trusted users,
@ simply select the <span class="capability">developer</span> privilege to
@ cause the new user to inherit all privileges of the
@ <span class="usertype">developer</span>
@ user. Similarly, the <span class="usertype">reader</span> user is a
@ template for users who are allowed more access than
@ <span class="usertype">anonymous</span>,
@ but less than a <span class="usertype">developer</span>.

** this file was generated by the 'parse_bitrel' program in the tools section
** using the data files from directory 'tools/data/3565'
**
** sha1_dvs contains a list of SHA-1 Disturbance Vectors (DV) to check
** dvType, dvK and dvB define the DV: I(K,B) or II(K,B) (see the paper)
** dm[80] is the expanded message block XOR-difference defined by the DV
** testt is the step to do the recompression from for collision detection
** maski and maskb define the bit to check for each DV in the dvmask returned by ubc_check
**
** ubc_check takes as input an expanded message block and verifies the unavoidable bitconditions for all listed DVs
** it returns a dvmask where each bit belonging to a DV is set if all unavoidable bitconditions for that DV have been met
** thus one needs to do the recompression check for each DV that has its bit set
**
** ubc_check is programmatically generated and the unavoidable bitconditions have been hardcoded
** a directly verifiable version named ubc_check_verify can be found in ubc_check_verify.c
** ubc_check has been verified against ubc_check_verify using the 'ubc_check_test' program in the tools section

**
** Additional entries defined by the "sitemap-extra" setting are included
** in the sitemap. "sitemap-extra" should be a TCL script with three
** values per entry:
**
** * The displayed text
**
** * The URL
**
** * A "capexpr" expression that determines whether or not to include
** the entry based on user capabilities. "*" means always include
** the entry and "{}" means never.
**
** If the "e=1" query parameter is present, then the standard content
** is omitted and only the sitemap-extra content is shown. If "e=2" is
** present, then only the standard content is shown and sitemap-extra
** content is omitted.
**
** If the "popup" query parameter is present and this is a POST request
** from the same origin, then the normal HTML header and footer information
** is omitted and the HTML text returned is just a raw "<ul>...</ul>".

** The 2nd parameter is a ranking of how important this alternative

** lower rank (i.e. higher priority) will overwrite a previous
** setting. This approach is used because the CGI/server-time
** initialization happens in an order which is incompatible with our
** preferred ranking, making it otherwise more invasive to tell the
** internals "the --skin flag ranks higher than a URL parameter" (the
** former gets initialized before both URL parameters and the /draft
** path determination).
**
** The rankings were initially defined in
** https://fossil-scm.org/forum/forumpost/caf8c9a8bb
** but where subsequently revised:
**
** 0) A skin name matching the glob pattern "draft[1-9]" at the start of
** the PATH_INFO.
**
** 1) The --skin flag for commands like "fossil ui", "fossil server", or
** "fossil http", or the "skin:" CGI config setting.
**
** 2) The "skin" display setting cookie or URL argument, in that
** order. If the "skin" URL argument is provided and refers to a legal
** skin then that will update the display cookie. If the skin name is
** illegal it is silently ignored.
**
** 3) The built-in skin identfied by the "default-skin" setting, if such
** a setting exists and matches one of the built-in skin names.
**
** 4) Skin properties (settings "css", "details", "footer", "header",
** and "js") from the CONFIG db table
**
** 5) The built-in skin named "default"
**
** The iSource integer privides additional detail about where the skin
**
** As a special case, a NULL or empty name resets zAltSkinDir and
** pAltSkin to 0 to indicate that the current config-side skin should
** be used (rank 3, above), then returns 0.

/* Javascript code that will enables sorting of the table. This code is
** derived from
**
** http://www.webtoolkit.info/sortable-html-table.html
**
** but with extensive modifications.
**
** All tables with class "sortable" are registered with the SortableTable()
** function. Example:
**
** <table class='sortable' data-column-types='tnkx' data-init-sort='2'>
**
** Column data types are determined by the data-column-types attribute of
** the table. The value of data-column-types is a string where each
** character of the string represents a datatype for one column in the
** table.
**
** t Sort by text
** n Sort numerically
** k Sort by the data-sortkey property
** x This column is not sortable
**
** Capital letters mean sort in reverse order.
** If there are fewer characters in zColumnTypes[] than their are columns,
** then all extra columns assume type "t" (text).
**
** If a column of the table is initially sorted, then the data-init-sort
** attribute should be set to the 1-based index of that column. (The
** left-most column is 1, the next column to the right is 2, and so forth.)
** A value of 0 in the data-init-sort attribute indicates that no columns
** where initially sorted.
**
** Clicking on the same column header twice in a row inverts the sort.

If a captcha string consists of just hexadecimal digits (as is the case for captchas generated by the [captcha.c module](/finfo/src/captcha.c)) then these WAV files can be concatenated together to generate an audio reading of the captcha, which enables visually impaired users to complete the captcha. Each of the WAV files uses 8000 samples per second, 8 bits per sample and are 6000 samples in length. The recordings are made by Philip Bennefall and are of his own voice. Mr. Bennefall is himself blind and uses this system implemented with these recordings to complete captchas for Fossil. |

** COMMAND: sql
** COMMAND: sqlite3*
**
** Usage: %fossil sql ?OPTIONS?
**
** Run the sqlite3 command-line shell on the Fossil repository
** identified by the -R option, or on the current repository.
** See https://www.sqlite.org/cli.html for additional information about
** the sqlite3 command-line shell.
**
** WARNING: Careless use of this command can corrupt a Fossil repository
** in ways that are unrecoverable. Be sure you know what you are doing before
** running any SQL commands that modify the repository database. Use the
** --readonly option to prevent accidental damage to the repository.
**
** Options:
** --no-repository Skip opening the repository database
** --readonly Open the repository read-only. No changes
** are allowed. This is a recommended safety
** precaution to prevent repository damage.
** -R REPOSITORY Use REPOSITORY as the repository database
** --test Enable some testing and analysis features
** that are normally disabled.
**
** All of the standard sqlite3 command-line shell options should also
** work.
**
** The following SQL extensions are provided with this Fossil-enhanced
** version of the sqlite3 command-line shell:
**
** builtin A virtual table that contains one row for
** each datafile that is built into the Fossil
** binary.
**
** checkin_mtime(X,Y) Return the mtime for the file Y (a BLOB.RID)
** found in check-in X (another BLOB.RID value).
**
** compress(X) Compress text X with the same algorithm used
** to compress artifacts in the BLOB table.
**
** content(X) Return the content of artifact X. X can be an
** artifact hash or hash prefix or a tag. Artifacts
** are stored compressed and deltaed. This function
** does all necessary decompression and undeltaing.
**
** decompress(X) Decompress text X. Undoes the work of
** compress(X).
**
** delta_apply(X,D) Apply delta D to source blob X and return
** the result.
**
** delta_create(X,Y) Create and return a delta that will convert
** X into Y.
**
** delta_output_size(D) Return the number of bytes of output to expect
** when applying delta D
**
** delta_parse(D) A table-valued function that deconstructs
** delta D and returns rows for each element of
** that delta.
**
** files_of_checkin(X) A table-valued function that returns info on
** all files contained in check-in X. Example:
**
** SELECT * FROM files_of_checkin('trunk');
**
** helptext A virtual table with one row for each command,
** webpage, and setting together with the built-in
** help text.
**
** now() Return the number of seconds since 1970.
**
** obscure(T) Obfuscate the text password T so that its
** original value is not readily visible. Fossil
** uses this same algorithm when storing passwords
** of remote URLs.
**
** regexp The REGEXP operator works, unlike in
** standard SQLite.
**
** symbolic_name_to_rid(X) Return the BLOB.RID corresponding to symbolic
** name X.

** COMMAND: stash
**
** Usage: %fossil stash SUBCOMMAND ARGS...
**
** > fossil stash
** > fossil stash save ?-m|--comment COMMENT? ?FILES...?
** > fossil stash snapshot ?-m|--comment COMMENT? ?FILES...?
**
** Save the current changes in the working tree as a new stash.
** Then revert the changes back to the last check-in. If FILES
** are listed, then only stash and revert the named files. The
** "save" verb can be omitted if and only if there are no other
** arguments. The "snapshot" verb works the same as "save" but
** omits the revert, keeping the check-out unchanged.
**
** > fossil stash list|ls ?-v|--verbose? ?-W|--width NUM?
**
** List all changes sets currently stashed. Show information about
** individual files in each changeset if -v or --verbose is used.
**
** > fossil stash show|cat ?STASHID? ?DIFF-OPTIONS?
** > fossil stash gshow|gcat ?STASHID? ?DIFF-OPTIONS?
**
** Show the contents of a stash as a diff against its baseline.
** With gshow and gcat, gdiff-command is used instead of internal
** diff logic.
**
** > fossil stash pop
** > fossil stash apply ?STASHID?
**
** Apply STASHID or the most recently created stash to the current
** working check-out. The "pop" command deletes that changeset from
** the stash after applying it but the "apply" command retains the
** changeset.
**
** > fossil stash goto ?STASHID?
**
** Update to the baseline check-out for STASHID then apply the
** changes of STASHID. Keep STASHID so that it can be reused
** This command is undoable.
**
** > fossil stash drop|rm ?STASHID? ?-a|--all?
**
** Forget everything about STASHID. Forget the whole stash if the
** -a|--all flag is used. Individual drops are undoable but -a|--all
** is not.
**
** > fossil stash diff ?STASHID? ?DIFF-OPTIONS?
** > fossil stash gdiff ?STASHID? ?DIFF-OPTIONS?
**
** Show diffs of the current working directory and what that
** directory would be if STASHID were applied. With gdiff,
** gdiff-command is used instead of internal diff logic.

** Generate and return an anchor tag like this:

** or <a id="ID">
**
** The form of the anchor tag is determined by the g.jsHref
** and g.perm.Hyperlink variables.
**
** g.perm.Hyperlink g.jsHref Returned anchor format
** ---------------- -------- ------------------------
** 0 0 (empty string)
** 0 1 (empty string)
** 1 0 <a href="URL">
** 1 1 <a data-href="URL">
**
** No anchor tag is generated if g.perm.Hyperlink is false.
** The href="URL" form is used if g.jsHref is false.
** If g.jsHref is true then the data-href="URL" and
** href="/honeypot" is generated and javascript is added to the footer
** to cause data-href values to be inserted into href
** after the page has loaded. The use of the data-href="URL" form
** instead of href="URL" is a defense against bots.
**
** If the user lacks the Hyperlink (h) property and the "auto-hyperlink"
** setting is true, then g.perm.Hyperlink is changed from 0 to 1 and
** g.jsHref is set to 1 by login_check_credentials(). Thus
** the g.perm.Hyperlink property will be true even if the user does not
** have the "h" privilege if the "auto-hyperlink" setting is true.
**
** User has "h" auto-hyperlink g.perm.Hyperlink g.jsHref
** ------------ -------------- ---------------- ---------------------
** 0 0 0 0
** 1 0 1 0
** 0 1 1 1
** 1 1 1 0
**
** So, in other words, tracing input configuration to final actions we have:
**
** User has "h" auto-hyperlink Returned anchor format
** ------------ -------------- ----------------------
** 0 0 (empty string)
** 1 0 <a href="URL">
** 0 1 <a data-href="URL">
** 1 1 <a href="URL">
**
** The name of these routines are deliberately kept short so that can be
** easily used within @-lines. Example:
**
** @ %z(href("%R/artifact/%s",zUuid))%h(zFN)</a>
**
** Note %z format. The string returned by this function is always
** obtained from fossil_malloc() so rendering it with %z will reclaim
** that memory space.
**
** There are three versions of this routine:
**
** (1) href() does a plain hyperlink
** (2) xhref() adds extra attribute text
** (3) chref() adds a class name
**
** g.perm.Hyperlink is true if the user has the Hyperlink (h) property.
** Most logged in users should have this property, since we can assume
** that a logged in user is not a bot. Only "nobody" lacks g.perm.Hyperlink,
** typically.

Problems related to max-height:
- If we do NOT set a max-height then pasting/typing a large amount
of text can cause this element to grow without bounds, larger than
the window, and there's no way to navigate it sensibly. In this
case, manually resizing the element (desktop only - mobile doesn't
offer that) will force it to stay at the selected size even if more
content is added to it later.
- If we DO set a max-height then its growth is bounded but it also
cannot manually expanded by the user.
The lesser of the two evils seems to be to rely on the browser
feature that a manual resize of the element will pin its size.

** COMMAND: remote
** COMMAND: remote-url*
**
** Usage: %fossil remote ?SUBCOMMAND ...?
**
** View or modify the URLs of remote repositories used for syncing.
** The "default" remote is specially named by Fossil and corresponds to
** the URL used in the most recent "sync", "push", "pull", "clone", or
** similar command. As such, the default remote can be updated by
** Fossil with each sync command. Other named remotes are persistent.
**
** > fossil remote
**
** With no arguments, this command shows the current default remote
** URL. If there is no default, it shows "off".
**
** > fossil remote add NAME URL
**
** Add a new named URL. Afterwards, NAME can be used as a short
** symbolic name for URL in contexts where a URL is required. The
** URL argument can be "default" or a prior symbolic name to make
** a copy of an existing URL under the new NAME. The "default"
** remote cannot be defined with this subcommand; instead,
** use 'fossil remote REF' as documented below.
**
** > fossil remote config-data
**
** DEBUG USE ONLY - Show the name and value of every CONFIG table
** entry in the repository that is associated with the remote URL store.
** Passwords are obscured in the output.
**
** > fossil remote delete NAME
**
** Delete a named URL previously created by the "add" subcommand.
**
** > fossil remote hyperlink ?FILENAME? ?LINENUM? ?LINENUM?
**
** Print a URL that will access the current check-out on the remote
** repository. Or if the FILENAME argument is included, print the
** URL to access that particular file within the current check-out.
** If one or two linenumber arguments are provided after the filename,
** then the URL is for the line or range of lines specified.
**
** > fossil remote list|ls
**
** Show all remote repository URLs.
**
** > fossil remote off
**
** Forget the default URL. This disables autosync.
**
** This is a convenient way to enter "airplane mode". To enter
** airplane mode, first save the current default URL, then turn the
** default off. Perhaps like this:
**
** fossil remote add main default
** fossil remote off
**
** To exit airplane mode and turn autosync back on again:
**
** fossil remote main
**
** > fossil remote scrub
**
** Forget any saved passwords for remote repositories, but continue
** to remember the URLs themselves. You will be prompted for the
** password the next time it is needed.
**
** > fossil remote ui ?FILENAME? ?LINENUM? ?LINENUM?
**
** Bring up a web browser pointing at the remote repository, and
** specifically to the page that describes the current check-out
** on that remote repository. Or if FILENAME and/or LINENUM arguments
** are provided, to the specific file and range of lines. This
** command is similar to "fossil remote hyperlink" except that instead
** of printing the URL, it passes the URL off to the web browser.
**
** > fossil remote REF

** REF may be a URL or a NAME from a prior "add".

** COMMAND: tag
**
** Usage: %fossil tag SUBCOMMAND ...
**
** Run various subcommands to control tags and properties.
**
** > fossil tag add ?OPTIONS? TAGNAME ARTIFACT-ID ?VALUE?
**
** Add a new tag or property to an artifact referenced by
** ARTIFACT-ID. For check-ins, the tag will be usable instead
** of a CHECK-IN in commands such as update and merge. If the
** --propagate flag is present and ARTIFACT-ID refers to a
** wiki page, forum post, technote, or check-in, the tag
** propagates to all descendants of that artifact.
**
** Options:
** --date-override DATETIME Set date and time added
** -n|--dry-run Display the tag text, but do not
** actually insert it into the database
** --propagate Propagating tag
** --raw Raw tag name. Ignored for
** non-CHECK-IN artifacts.
** --user-override USER Name USER when adding the tag
**
** The --date-override and --user-override options support
** importing history from other SCM systems. DATETIME has
** the form 'YYYY-MMM-DD HH:MM:SS'.
**
** Note that fossil uses some tag prefixes internally and this
** command will reject tags with these prefixes to avoid
** causing problems or confusion: "wiki-", "tkt-", "event-".
**
** > fossil tag cancel ?--raw? TAGNAME ARTIFACT-ID
**
** Remove the tag TAGNAME from the artifact referenced by
** ARTIFACT-ID, and also remove the propagation of the tag to
** any descendants. Use the the -n|--dry-run option to see
** what would have happened. Certain tag name prefixes are
** forbidden, as documented for the 'add' subcommand.
**
** Options:
** --date-override DATETIME Set date and time deleted
** -n|--dry-run Display the control artifact, but do
** not insert it into the database
** --raw Raw tag name. Ignored for
** non-CHECK-IN artifacts.
** --user-override USER Name USER when deleting the tag
**
** > fossil tag find ?OPTIONS? TAGNAME
**
** List all objects that use TAGNAME.
**
** Options:
** -n|--limit N Limit to N results
** --raw Interprets tag as a raw name instead of a
** branch name and matches any type of artifact.
** Changes the output to include only the
** hashes of matching objects.
** -t|--type TYPE One of: ci (check-in), w (wiki),
** e (event/technote), f (forum post),
** t (ticket). Default is all types. Ignored
** if --raw is used.
**
** > fossil tag list|ls ?OPTIONS? ?ARTIFACT-ID?
**
** List all tags or, if ARTIFACT-ID is supplied, all tags and
** their values for that artifact. The tagtype option accepts
** one of: propagated, singleton, cancel. For historical
** scripting compatibility, the internal tag types "wiki-",
** "tkt-", and "event-" (technote) are elided by default
** unless the --raw or --prefix options are used.
**
** Options:
** -v|--inverse Inverse the meaning of --tagtype TYPE
** --prefix List only tags with the given prefix
** Fossil-internal prefixes include "sym-"
** (branch name), "wiki-", "event-"
** (technote), and "tkt-" (ticket). The
** prefix is stripped from the resulting
** list unless --raw is provided. Ignored if
** ARTIFACT-ID is provided.
** --raw List raw names of tags
** --sep SEP Separator when concatenating values
** --tagtype TYPE List only tags of type TYPE, which must
** be one of: cancel, singleton, propagated
** --values List tag values
** If --sep is supplied, list all values of a tag on
** the same line, separated by SEP; otherwise list
** each value on its own line.
**
** The option --raw allows the manipulation of all types of tags
** used for various internal purposes in fossil. It also shows
** "cancel" tags for the "find" and "list" subcommands. You should
** not use this option to make changes unless you are sure what
** you are doing.

**
** --test Make database entries but do not add the tag artifact.
** So the reparent operation will be undone by the next
** "fossil rebuild" command.
** -n|--dry-run Print the tag that would have been created but do not
** actually change the database in any way.

**
** The 'tar' format has evolved over time. Initially the name was stored
** in a 100 byte null-terminated field 'name'. File path names were
** limited to 99 bytes.
**
** The Posix.1 'ustar' format added a 155 byte field 'prefix', allowing
** for up to 255 characters to be stored. The full file path is formed by
** concatenating the field 'prefix', a slash, and the field 'name'. This
** gives some measure of compatibility with programs that only understand
** the oldest format.
**
** The latest Posix extension is called the 'pax Interchange Format'.
** It removes all the limitations of the previous two formats by allowing
** the storage of arbitrary-length attributes in a separate object that looks
** like a file to programs that do not understand this extension. So the
** contents of the 'name' and 'prefix' fields should contain values that allow
** versions of tar that do not understand this extension to still do
** something useful.

**
** cmdhook Executes the TH1 procedure [command_hook], after

** and "cmd_flags" to appropriate values.
**
** cmdnotify Executes the TH1 procedure [command_notify], after

** of one of these keywords:
**
** before
** after
** descendants | children
** ancestors | parents
**
** The CHECKIN can be any unique prefix of 4 characters or more. You
** can also say "current" for the current version.
**
** DATETIME may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in
** year-month-day form, it may be truncated, the "T" may be replaced by
** a space, and it may also name a timezone offset from UTC as "-HH:MM"
** (westward) or "+HH:MM" (eastward). Either no timezone suffix or "Z"
** means UTC.
**
**
** Options:
** -b|--branch BRANCH Show only items on the branch named BRANCH
** -c|--current-branch Show only items on the current branch
** -F|--format Entry format. Values "oneline", "medium", and "full"
** get mapped to the full options below. Otherwise a
** string which can contain these placeholders:
** %n newline
** %% a raw %
** %H commit hash
** %h abbreviated commit hash
** %a author name
** %d date
** %c comment (NL, TAB replaced by space, LF erased)
** %b branch
** %t tags
** %p phase: zero or more of *CURRENT*, *MERGE*,
** *FORK*, *UNPUBLISHED*, *LEAF*, *BRANCH*
** --oneline Show only short hash and comment for each entry
** --medium Medium-verbose entry formatting
** --full Extra verbose entry formatting
** -n|--limit N If N is positive, output the first N entries. If
** N is negative, output the first -N lines. If N is
** zero, no limit. Default is -20 meaning 20 lines.
** --offset P Skip P changes
** -p|--path PATH Output items affecting PATH only.
** PATH can be a file or a sub directory.
** -R REPO_FILE Specifies the repository db to use. Default is
** the current check-out's repository.
** --sql Show the SQL used to generate the timeline
** -t|--type TYPE Output items from the given types only, such as:
** ci = file commits only
** e = technical notes only
** f = forum posts only
** t = tickets only
** w = wiki commits only
** -v|--verbose Output the list of files changed by each commit
** and the type of each change (edited, deleted,
** etc.) after the check-in comment.
** -W|--width N Width of lines (default is to auto-detect). N must be
** either greater than 20 or it must be zero 0 to
** indicate no limit, resulting in a single line per
** entry.

** COMMAND: ticket*
**
** Usage: %fossil ticket SUBCOMMAND ...
**
** Run various subcommands to control tickets
**
** > fossil ticket show (REPORTTITLE|REPORTNR) ?TICKETFILTER? ?OPTIONS?
**
** Options:
** -l|--limit LIMITCHAR
** -q|--quote
** -R|--repository REPO
**
** Run the ticket report, identified by the report format title
** used in the GUI. The data is written as flat file on stdout,
** using TAB as separator. The separator can be changed using
** the -l or --limit option.
**
** If TICKETFILTER is given on the commandline, the query is
** limited with a new WHERE-condition.
** example: Report lists a column # with the uuid
** TICKETFILTER may be [#]='uuuuuuuuu'
** example: Report only lists rows with status not open
** TICKETFILTER: status != 'open'
**
** If --quote is used, the tickets are encoded by quoting special
** chars (space -> \\s, tab -> \\t, newline -> \\n, cr -> \\r,
** formfeed -> \\f, vtab -> \\v, nul -> \\0, \\ -> \\\\).
** Otherwise, the simplified encoding as on the show report raw page
** in the GUI is used. This has no effect in JSON mode.
**
** Instead of the report title it's possible to use the report
** number; the special report number 0 lists all columns defined in
** the ticket table.
**
** > fossil ticket list fields
** > fossil ticket ls fields
**
** List all fields defined for ticket in the fossil repository.
**
** > fossil ticket list reports
** > fossil ticket ls reports
**
** List all ticket reports defined in the fossil repository.
**
** > fossil ticket set TICKETUUID (FIELD VALUE)+ ?-q|--quote?
** > fossil ticket change TICKETUUID (FIELD VALUE)+ ?-q|--quote?
**
** Change ticket identified by TICKETUUID to set the values of
** each field FIELD to VALUE.
**
** Field names as defined in the TICKET table. By default, these
** names include: type, status, subsystem, priority, severity, foundin,
** resolution, title, and comment, but other field names can be added
** or substituted in customized installations.
**
** If you use +FIELD, the VALUE is appended to the field FIELD. You
** can use more than one field/value pair on the commandline. Using
** --quote enables the special character decoding as in "ticket
** show", which allows setting multiline text or text with special
** characters.
**
** > fossil ticket add FIELD VALUE ?FIELD VALUE .. ? ?-q|--quote?
**
** Like set, but create a new ticket with the given values.
**
** > fossil ticket history TICKETUUID
**
** Show the complete change history for the ticket
**
** Note that the values in set|add are not validated against the
** definitions given in "Ticket Common Script".

** COMMAND: undo

** * fossil update
** * fossil merge
** * fossil revert
** * fossil stash pop
** * fossil stash apply
** * fossil stash drop
** * fossil stash goto
** * fossil clean (*see note below*)
**
** Note: The "fossil clean" command only saves state for files less than
** 10MiB in size and so if fossil clean deleted files larger than that,
** then "fossil undo" will not recover the larger files.
**
** If FILENAME is specified then restore the content of the named
** file(s) but otherwise leave the update or merge or revert in effect.
** The redo command undoes the effect of the most recent undo.
**
** If the -n|--dry-run option is present, no changes are made and instead
** the undo or redo command explains what actions the undo or redo would
** have done had the -n|--dry-run been omitted.
**
** If the most recent command is not one of those listed as undoable,
** then the undo command might try to restore the state to be what it was
** prior to the last undoable command, or it might be a no-op. If in
** doubt about what the undo command will do, first run it with the -n
** option.
**
** A single level of undo/redo is supported. The undo/redo stack
** is cleared by the commit and check-out commands. Other commands may
** or may not clear the undo stack.
**
** Future versions of Fossil might add new commands to the set of commands
** that are undoable.
**
** Options:
** -n|--dry-run Do not make changes, but show what would be done

** COMMAND: uv#

**
** Unversioned files (UV-files) are artifacts that are synced and are available
** for download but which do not preserve history. Only the most recent version
** of each UV-file is retained. Changes to an UV-file are permanent and cannot
** be undone, so use appropriate caution with this command.
**
** Subcommands:
**
** add FILE ... Add or update one or more unversioned files in
** the local repository so that they match FILEs
** on disk. Changes are not pushed to other
** repositories until the next sync.
**
** add FILE --as UVFILE Add or update a single file named FILE on disk
** and UVFILE in the repository unversioned file
** namespace. This variant of the 'add' command allows
** the name to be different in the repository versus
** what appears on disk, but it only allows adding
** a single file at a time.
**
** cat FILE ... Concatenate the content of FILEs to stdout.
**
** edit FILE Bring up FILE in a text editor for modification.
**
** export FILE OUTPUT Write the content of FILE into OUTPUT on disk
**
** list | ls Show all unversioned files held in the local
** repository.
**
** Options:
** --glob PATTERN Show only files that match
** --like PATTERN Show only files that match
** -l Show additional details for
** files that match. Implied
** when 'list' is used.
**
** revert ?URL? Restore the state of all unversioned files in the
** local repository to match the remote repository
** URL.
**
** Options:
** -v|--verbose Extra diagnostic output
** -n|--dry-run Show what would have happened
**
** remove|rm|delete FILE ...
** Remove unversioned files from the local repository.
** Changes are not pushed to other repositories until
** the next sync.
**
** Options:
** --glob PATTERN Remove files that match
** --like PATTERN Remove files that match
**
** sync ?URL? Synchronize the state of all unversioned files with
** the remote repository URL. The most recent version
** of each file is propagated to all repositories and
** all prior versions are permanently forgotten.
** The remote account requires the 'y' capability.
**
** Options:
** -v|--verbose Extra diagnostic output
** -n|--dry-run Show what would have happened
**
** touch FILE ... Update the TIMESTAMP on all of the listed files
**
** Options:
** --mtime TIMESTAMP Use TIMESTAMP instead of "now" for the "add",
** "edit", "remove", and "touch" subcommands.
** -R|--repository REPO Use REPO as the repository

** COMMAND: update
**
** Usage: %fossil update ?OPTIONS? ?VERSION? ?FILES...?
**
** Change the version of the current check-out to VERSION. Any
** uncommitted changes are retained and applied to the new check-out.
**
** The VERSION argument can be a specific version or tag or branch
** name. If the VERSION argument is omitted, then the leaf of the
** subtree that begins at the current version is used, if there is
** only a single leaf. VERSION can also be "current" to select the
** leaf of the current version or "latest" to select the most recent
** check-in.
**
** If one or more FILES are listed after the VERSION then only the
** named files are candidates to be updated, and any updates to them
** will be treated as edits to the current version. Using a directory
** name for one of the FILES arguments is the same as using every
** subdirectory and file beneath that directory.
**
** If FILES is omitted, all files in the current check-out are subject
** to being updated and the version of the current check-out is changed
** to VERSION. Any uncommitted changes are retained and applied to the
** new check-out.
**
** The -n or --dry-run option causes this command to do a "dry run".
** It prints out what would have happened but does not actually make
** any changes to the current check-out or the repository.
**
** The -v or --verbose option prints status information about
** unchanged files in addition to those file that actually do change.
**
** Options:
** --case-sensitive BOOL Override case-sensitive setting
** --debug Print debug information on stdout
** -n|--dry-run If given, display instead of run actions
** --force-missing Force update if missing content after sync
** -K|--keep-merge-files On merge conflict, retain the temporary files
** used for merging, named *-baseline, *-original,
** and *-merge.
** --latest Acceptable in place of VERSION, update to
** latest version
** --nosync Do not auto-sync prior to update
** --setmtime Set timestamps of all files to match their
** SCM-side times (the timestamp of the last
** check-in which modified them).
** -v|--verbose Print status information about all files
** -W|--width WIDTH Width of lines (default is to auto-detect).
** Must be more than 20 or 0 (= no limit,
** resulting in a single line per entry).
**
** See also: [[revert]]

** the output filename are created if needed.
** If PAGENAME is provided, the named wiki page will be output.
**
** Options:
** -t|--technote DATETIME|TECHNOTE-ID|TAG
** Specifies that a technote, rather than a wiki page,
** will be exported. If DATETIME is used, the most
** recently modified tech note with that DATETIME will
** output. If TAG is used, the most recently modified
** tech note with that TAG will be output.
** -h|--html The body (only) is rendered in HTML form, without
** any page header/foot or HTML/BODY tag wrappers.
** -H|--HTML Works like -h|-html but wraps the output in
** <html><body>...</body></html>.
** -p|--pre If -h|-H is used and the page or technote has
** the text/plain mimetype, its HTML-escaped output
** will be wrapped in <pre>...</pre>.
**
** > fossil wiki (create|commit) (PAGENAME | TECHNOTE-COMMENT) ?FILE? ?OPTIONS?
**
** Create a new or commit changes to an existing wiki page or
** technote from FILE or from standard input. PAGENAME is the
** name of the wiki entry. TECHNOTE-COMMENT is the timeline comment of
** the technote.
**
** Options:
** -M|--mimetype TEXT-FORMAT The mime type of the update.
** Defaults to the type used by
** the previous version of the
** page, or text/x-fossil-wiki.
** Valid values are: text/x-fossil-wiki,
** text/x-markdown and text/plain. fossil,
** markdown or plain can be specified as
** synonyms of these values.
** -t|--technote DATETIME Specifies the timestamp of
** the technote to be created or
** updated. The timestamp specifies when
** this technote appears in the timeline
** and is its permanent handle although
** it may not be unique. When updating
** a technote the most recently modified
** tech note with the specified timestamp
** will be updated.
** -t|--technote TECHNOTE-ID Specifies the technote to be
** updated by its technote id, which is
** its UUID.
** --technote-tags TAGS The set of tags for a technote.
** --technote-bgcolor COLOR The color used for the technote
** on the timeline.
**
** > fossil wiki list ?OPTIONS?
** > fossil wiki ls ?OPTIONS?
**
** Lists all wiki entries, one per line, ordered
** case-insensitively by name. Wiki pages associated with
** check-ins and branches are NOT shown, unless -a is given.
**
** Options:
** --all Include "deleted" pages in output.
** By default deleted pages are elided.
** -t|--technote Technotes will be listed instead of
** pages. The technotes will be in order
** of timestamp with the most recent
** first.
** -a|--show-associated Show wiki pages associated with
** check-ins and branches.
** -s|--show-technote-ids The id of the tech note will be listed
** along side the timestamp. The tech note
** id will be the first word on each line.
** This option only applies if the
** --technote option is also specified.
**
** DATETIME may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in
** year-month-day form, it may be truncated, the "T" may be replaced by
** a space, and it may also name a timezone offset from UTC as "-HH:MM"
** (westward) or "+HH:MM" (eastward). Either no timezone suffix or "Z"
** means UTC.
**
** The "Sandbox" wiki pseudo-page is a special case. Its name is
** checked case-insensitively and either "create" or "commit" may be
** used to update its contents.

<h2>Wiki Formatting Rule Summary</h2>
# Blank lines are paragraph breaks
# Bullets are "*" surrounded by two spaces at the beginning of a line
# Enumeration items are "#" or a digit and a "." surrounded by two
spaces at the beginning of a line
# Indented paragraphs begin with a tab or two spaces
# Hyperlinks are contained within square brackets:
<nowiki>"<b>[</b><i>target</i><b>]</b>"
or "<b>[</b><i>target</i><b>|</b><i>label</i><b>]</b>"</nowiki>
# Most ordinary HTML works
# <verbatim> and <nowiki>
We call the first five rules above the "wiki" formatting rules.
The last two rules are the HTML formatting rules.
<h2>Formatting Rule Details</h2>
1. <b>Paragraphs.</b>
Any sequence of one or more blank lines forms a paragraph break.
Centered or right-justified paragraphs are not supported by wiki markup,
but you can do these things if you need them using HTML.
2. <b>Bullet Lists.</b>
A bullet list item is a line that begins with a single "*" character
surrounded on both sides by two or more spaces or by a tab.
Only a single level of bullet list is supported by wiki.
For nested lists, use HTML.
3. <b>Enumeration Lists.</b>
An enumeration list item is a line that begins with a single "#"
character surrounded on both sides by two or more spaces or by a tab.
Or it can be a number and a "." (ex: "5.") surrounded on both sides
by two spaces or a tab.
Only a single level of enumeration list is supported by wiki.
For nested lists or for enumerations that count using letters or
roman numerals, use HTML.
4. <b>Indented Paragraphs.</b>
Any paragraph that begins with two or more spaces or a tab and which
is not a bullet or enumeration list item is rendered indented.
Only a single level of indentation is supported by wiki.
Use HTML for deeper indentation.
5. <b>Hyperlinks.</b>
Text within square brackets <nowiki>("[...]")</nowiki> becomes a
hyperlink. The target can be a wiki page name, the artifact ID of
a check-in or ticket, the name of an image, a URL, or an
[#intermap|interwiki link] of the form
"<i>Tag</i><b>:</b><i>PageName</i>".
By default, the target is displayed as the text of the hyperlink.
But you can specify alternative text after the target name
separated by a "|" character.
You can also link to internal anchor names using
<nowiki>[#anchor-name],</nowiki> providing you have added the necessary
"<a name='anchor-name'></a>" tag to your wiki page.
6. <b>HTML.</b>
The following standard HTML elements may be used:
<a> <address> <article> <aside> <b>
<big> <blockquote> <br> <center> <cite>
<code> <col> <colgroup> <dd>
<del> <dfn>
<div> <dl> <dt> <em> <font> <footer>
<ins>
<h1> <h2> <h3> <h4> <h5> <h6>
<header> <hr> <i> <img> <kbd> <li>
<nav> <nobr> <nowiki> <ol> <p> <pre>
<s> <samp> <section> <small> <span>
<strike> <strong> <sub> <sup> <table>
<tbody> <td> <tfoot> <th> <thead>
<title> <tr> <tt> <u> <ul> <var>
<verbatim>. There are two non-standard elements available:
<verbatim> and <nowiki>. No other elements are allowed.
All attributes are checked and only a few benign attributes are
allowed on each element. In particular, any attributes that specify
javascript or CSS are elided.
7. <b>Special Markup.</b>
The <nowiki> tag disables all wiki formatting rules through
the matching </nowiki> element. The <verbatim> tag works
like <pre> with the addition that it also disables all wiki
and HTML markup through the matching </verbatim>.
Text within
<tt><verbatim type="pikchr">...</verbatim></tt>
is formatted using <a href="https://pikchr.org/home">Pikchr</a>.
<a name="intermap"></a>
<h2>Interwiki Tag [/intermap|Map]</h2>

** components without directory separators ("basenames") are converted to UTF-16
** using fossil_utf8_to_path(), so bypassing its slash ↔ backslash translations.

**
** NOTE: As of Windows 10, version 1803, case sensitivity may be enabled on a
** per-directory basis, as returned by NtQueryInformationFile() with the file
** information class FILE_CASE_SENSITIVE_INFORMATION. So this function may be
** changed to act like fossil_strdup() for files located in such directories.

** COMMAND: winsrv*
**
** Usage: %fossil winsrv METHOD ?SERVICE-NAME? ?OPTIONS?
**
** Where METHOD is one of: create delete show start stop.
**
** The winsrv command manages Fossil as a Windows service. This allows
** (for example) Fossil to be running in the background when no user
** is logged in.
**
** In the following description of the methods, "Fossil-DSCM" will be
** used as the default SERVICE-NAME:
**
** %fossil winsrv create ?SERVICE-NAME? ?OPTIONS?
**
** Creates a service. Available options include:
**
** -D|--display DISPLAY-NAME
**
** Sets the display name of the service. This name is shown
** by graphical interface programs. By default, the display name
** equals to the service name.
**
** -S|--start TYPE
**
** Sets the start type of the service. TYPE can be "manual",
** which means you need to start the service yourself with the
** 'fossil winsrv start' command or with the "net start" command
** from the operating system. If TYPE is set to "auto", the service
** will be started automatically by the system during startup.
**
** --username USERNAME
**
** Specifies the user account which will be used to run the
** service. The account needs the "Logon as a service" right
** enabled in its profile. Specify local accounts as follows:
** ".\\USERNAME". By default, the "LocalSystem" account will be
** used.
**
** -W|--password PASSWORD
**
** Password for the user account.
**
** The following options are more or less the same as for the "server"
** command and influence the behaviour of the http server:
**
** --baseurl URL
**
** Use URL as the base (useful for reverse proxies)
**
** -P|--port TCPPORT
**
** Specifies the TCP port (default port is 8080) on which the
** server should listen.
**
** -R|--repository REPO
**
** Specifies the name of the repository to be served.
** The repository option may be omitted if the working directory
** is within an open check-out.
** The REPOSITORY can be a directory (aka folder) that contains
** one or more repositories with names ending in ".fossil".
** In that case, the first element of the URL is used to select
** among the various repositories.
**
** --notfound URL
**
** If REPOSITORY is a directory that contains one or more
** repositories with names of the form "*.fossil" then the
** first element of the URL pathname selects among the various
** repositories. If the pathname does not select a valid
** repository and the --notfound option is available,
** then the server redirects (HTTP code 302) to the URL of
** --notfound.
**
** --localauth
**
** Enables automatic login if the --localauth option is present
** and the "localauth" setting is off and the connection is from
** localhost.
**
** --repolist
**
** If REPOSITORY is directory, URL "/" lists all repositories.
**
** --scgi
**
** Create an SCGI server instead of an HTTP server
**
**
** %fossil winsrv delete ?SERVICE-NAME?
**
** Deletes a service. If the service is currently running, it will be
** stopped first and then deleted.
**
**
** %fossil winsrv show ?SERVICE-NAME?
**
** Shows how the service is configured and its current state.
**
**
** %fossil winsrv start ?SERVICE-NAME?
**
** Start the service.
**
**
** %fossil winsrv stop ?SERVICE-NAME?
**
** Stop the service.
**
**
** NOTE: This command is available on Windows operating systems only and
** requires administrative rights on the machine executed.

**
** This command was original created to help debug the server side of
** sync messages. The XFERFILE is the uncompressed content of an

** on standard output.
**
** One possible usages scenario is to capture some XFERFILE examples
** using a command like:
**
** fossil push http://bogus/ --httptrace
**
** The complete HTTP requests are stored in files named "http-request-N.txt".
** Find one of those requests, remove the HTTP header, and make other edits
** as necessary to generate an appropriate XFERFILE test case. Then run:
**
** fossil test-xfer xferfile.txt

This page contains URLs for file-age computations that have given
trouble in the past. Shift-click on on the links, one-by-one, to verify
that the current implementation works correctly:
* [/fileage?name=c9df0dcdaa402] - Verify that the many
execute permission changes that occurred about 24 hours before
check-in c9df0dcdaa402 do not appear as file changes.
* [/tree?ci=c9df0dcdaa40&mtime=0&type=tree] - Verify that all
three skin files (css.txt, footer.txt, and header.txt) appear
in all of the skin/*/ folders.
* On both of the above, check for excessive computation time.

# Reminder to self: in March 2012 i saw a corner-case which returns
# HTML output. To reproduce: chmod 444 REPO, then submit a request
# which writes something (timeline creates a temp table). The "repo
# is not writable" error comes back as HTML. i don't know if the
# error happens before we have made the determination that the app is
# in JSON mode or if the error handling is incorrectly not
# recognizing JSON mode.

Markdown Footnotes Test Document
================================
**This document** should help with testing of footnotes support that
is introduced by the ["`markdown-footnotes`"][branch] branch.
It **might look pretty misformatted unless rendered by the proper Fossil
executable** that incorporates the abovementioned branch.[^1]
That is also a humble attempt to explore the robustness of the Markdown parser.
So please excuse for the mess in the [source code of this document][src].
By no means the normal use of footnotes should look that scarry.
Developers are invited to add test cases here[^here].
It is suggested that the more simple is a test case the earlier it should
appear in this document.[^ if glitch occurs ]
[^lost3]: This note was defined at the begining of the document.
[^duplicate]: This came from the begining of the document.
A footnote's label should be case insensitive[^ case INSENSITIVE ],
it is whitespace-savvy and can even contain newlines.[^ a
multiline
label]
A labeled footnote may be [referenced several times][^many-refs].
A footnote's text should support Markdown [markup][^].
Markup within [a [text fragment](https://en.wikipedia.org/wiki/Lorem_ipsum)
of a *span-bounded footnote*][^markup] should also be rendered.
Another reference[^many-refs] to the preveously used footnote.
[^lost2]: This note was defined in the middle of the document.
It references [its previous][^lost3]
and [the forthcoming][^lost1] siblings.
[^i am strayed]:
This should be presented **verbatim** (without any [markup][^])
in the end of the footnotes.
Default skin renders label in red font and the main text in gray.
Other styling may also apply.
Inline footnotes are supported.(^These may be usefull for adding
<s>small</s> comments.)
This is a corner case that is rendered as [an empty footnote](^ [] ()).
If [undefined label is used][^] then red "`misref`" is emited instead of
a numeric marker.[^ see it yourself ]
This can be overridden by the skin though.
The refenrence at the end of this sentence is the sole reason of
rendering of <s>`lost1` and</s> [lost2][^].
If several labeled footnote definitions have the same equal label then texts
from all these definitions are joined.[^duplicate]
Several references should be recognized as several distinct numbers.
(^There should be an interval between numbers.) [^many-refs]
If markup is ambigous between a span-bounded footnote and
a "free-standing" footnote followed by another footnote
then interpret as the later case.
This facilitates the usage in the usual case
when several footnotes are refenrenced at the end
of a phrase.[^scipub][^many-refs](^All these four should
be parsed as "free-standing" footnotes)[^Coelurosauria]
An ambiguity between a link to an image and a *free-standing referenced
footnote* should be resolved as a footnote![^not-image]
A footnote may not be empty(^)
or consist just of blank characters.(^
)
The same holds for labeled footnotes. If definition of a labeled footnote
is blank then it is not accepted by the first pass of the parser and
is recognized during the second pass as misreference.
[^ This definition consists of just blanks ]:
<style>
li.fn-upc-example span.fn-upc {
border: solid 2px lightgreen;
border-radius: 0.25em;
padding-left: 2px;
padding-right: 2px;
margin-bottom: 0.2em;
}
li.fn-upc-example span.fn-upcDot:first-child {
font-weight: bold;
}
sup.noteref.fn-upc-example,
span.notescope.fn-upc-example sup.noteref {
border: solid 2px lightgreen;
[^duplicate]:
Labeled footnote definition may appear anywhere.
That part came from inside of an inline style definition.
border-radius: 0.4em;
padding: 2px;
}
sup.noteref.fn-upc-example::after,
span.notescope.fn-upc-example sup.noteref::after {
content: " ⛄";
}
sup.noteref.fn-upc-example:hover::after,
span.notescope.fn-upc-example sup.noteref:hover::after {
content: " 👻";
}
li.fn-upc-l span.fn-upc {
font-size: 60%;
color: orange;
}
li.fn-upc-l span.fn-upc span.fn-upcDot {
display: none;
}
</style>
It is possible to provide a list of classes for a particular footnote and
all its references. This is achieved by prepending a footnote's text with
a special token that starts with dot and ends with colon.
(^
.alpha-Numeric123.EXAMPLE:
This token defines a dot-separated list of CSS classes
which are added to that particular footnote and also to the
corresponding reference(s). Hypens ('-') are also allowed.
Classes from the token are tranformed to lowercase and are prepended
with `"fn-upc-"` to avoid collisions.
)
This feature is "*opt-in*": there is nothing wrong in starting a footnote's
text with a token of that form while not defining any corresponding classes
in the stylesheet.[^nostyle]
If a footnote consists just of a valid userclass token then this token
is not interpreted as such, instead it is emitted as plain text.
(^
.bare.classlist.inside.inline.footnote:
)[^bare1]
[^bare2]
[^duplicate]: .with.UPC.token:
When duplicates are joined their UPC tokens are treated as plain-text.
Blank characters between token and main text must be preserved.
<html>
Click
<a href="?a=B"e='&nonASCII=😂&script=<script>alert('Broken!');</script>">
here</a> and
<a href='?a=B"e="&nonASCII=😂&script=<script>alert("Broken!");</script>'>
here</a>
to test escaping of REQUEST_URI in the generated footnote markers.
</html>
A depth of nesting must be limited.
(^
.L.1: A long chain of nested inline footnotes...
(^
.L.2: is a rather unusual thing...
(^
.L.3: and requires extra CPU cycles for processing.
(^
.L.4: Theoretically speaking O(n<sup>2</sup>).
(^
.L.5: Thus it is worth dismissing those footnotes...
(^
.L.6: that are nested deeper than on a certain level.
(^
.L.7: A particular value for that limit...
(^
is hard-coded in src/markdown.c ...
(^
in function `markdown()` ...
(^
in variable named `maxDepth`.
(^
For the time being, its value is **5**

## Footnotes
[branch]: /timeline?r=markdown-footnotes&nowiki
[^ 1]: Footnotes is a Fossil extension of
Markdown. Your other tools may have limited support for these.
[^here]: [History of test/markdown-test3.md](/finfo/test/markdown-test3.md)
[src]: /file/test/markdown-test3.md?ci=markdown-footnotes&txt&ln
[^if glitch occurs]:
So that simple cases are processed even if
a glitch happens for more tricky cases.
[^ CASE insensitive ]: And also tolerate whitespaces.
[^ a multiline label ]: But at a footnote's definition it should still
be written within square brackets
on a single line.
[^duplicate]: And that came from the end of the document.
[^many-refs]:
Each letter on the left is a back-reference to the place of use.
Highlighted back-reference indicates a place from which navigation
occurred[^lost1].
[^lost1]: This note was defined at the end of the document.
It defines an inline note.
(^This is inline note defined inside of [a labeled note][^lost1].)
[^markup]: E.g. *emphasis*, and [so on](/md_rules).
BTW, this note may not have a backreference to the "stray".
[^undefined label is used]: For example due to a typo.
[^not-image]: The rationale is that URLs do not start with **^**
while a footnote may follow *immediately* after an exclamation mark
at the end of a sentence.
[^another stray]: Just to verify the correctness of ordering and styling.
[^scipub]: Which is common in the scientific publications.
[^bare1]: .at.the.1st.line.of.labeled.footnote.definition:
[^bare2]:
.at.the.2nd.line.of.labeled.footnote.definition:
[^stray with UPC]: .UPC-token:
A token of user-provided classes must be rendered within strays.
Aslo: this and the previous line may not have extra indentation.
[^nostyle]:
.unused.classes:
In that case text of the footnote just looks like as if
no special processing occured.
[^ <script>alert("You have been pwned!");</script> ]: Labels are escaped
[^ <textarea>"Last words here...' ]:
<textarea>Content is also escaped</textarea>

<title>Release Checklist</title>
This file describes the testing procedures for Fossil prior to an
official release.
<ol>
<li><p>
From within a checkout of the Fossil tree, display this file with
the command "<b>fossil ui --page doc/ckout/test/release-checklist.wiki</b>".
That is the only way the links below will work.
<li><p>
From a private directory (not the source tree) run
"<b>tclsh $SRC/test/tester.tcl $FOSSIL</b>" where $FOSSIL is the
name of the executable under test and $SRC is the source tree.
Verify that there are no errors.
<li><p>
Click on each of the links in in the
[./graph-test-1.wiki] document and verify that all graphs are
rendered correctly.
<li><p>
Click on each of the links in in the
[./graph-test-2.md] document and verify that all graphs are
rendered correctly.

<li> Also view the same check-ins on a /timeline
view by clicking on the date for each check-in in the /info
view, as the graph rendering is slightly different.
</ol>
<li><p>
Click on each of the links in in the
[./diff-test-1.wiki] document and verify that all diffs are
rendered correctly.
<li><p>
Click on the following link to verify that it works: [./test-page%2b%2b.wiki | ./test-page++.wiki]
(NB: Many web servers automatically block
or rewrite URLs that contain "+" characters, even when those "+"
characters are encoded as "%2B". On such web servers, the URL
above will not work. This test is only guaranteed to work
when running "fossil ui".)
<li><p>
Shift-click on each of the links in [./fileage-test-1.wiki] and verify
correct operation of the file-age computation.
<li><p>
Verify correct name-change tracking behavior (no net changes) for:
<pre><b>fossil test-name-changes --debug b120bc8b262ac 374920b20944b
</b></pre>
<li><p>
Compile for all of the following platforms:
<ol type="a">
<li> Linux x86
<li> Linux x86_64
<li> Mac x86
<li> Mac x86_64
<li> Windows (mingw)
<li> Windows (vc++)
<li> OpenBSD
</ol>
<li><p>
Run at least one occurrence of the following commands on every
platform:
<ol type="a">
<li> <b>fossil rebuild</b>
<li> <b>fossil sync</b>
<li> <b>fossil test-integrity</b>
</ol>
<li><p>
Run the following commands on Linux and verify no major memory leaks
and no run-time errors or warnings (except for the well-known jump on an
uninitialized value that occurs within zlib).</p>
<ol type="a">
<li> <b>valgrind fossil rebuild</b>
<li> <b>valgrind fossil sync</b>
</ol>
<p>Achtung: make sure to point valgrind to the proper fossil binary
so that it does not pick up another from the PATH.</p>
<li><p>
Inspect [http://fossil-scm.org/home/vdiff?from=release&to=trunk&sbs=1|all code changes since the previous release], paying particular
attention to the following details:
<ol type="a">
<li> Can a malicious HTTP request cause a buffer overrun.
<li> Can a malicious HTTP request expose privileged information to
unauthorized users.
</ol>
<li><p>
Use the release candidate version of fossil in production on the
[http://fossil-scm.org/] website for at least 48 hours (without
incident) prior to making the release official.
<li><p>
Verify that the minimum SQLite version requirement is up-to-date:
<ol type="a">
<li> Check the version number in the line starting "define MINIMUM_SQLITE_VERSION" near the top of [/file?name=auto.def&ci=tip | auto.def]
<li> Check the output of <b>./configure --print-minimum-sqlite-version</b>
</ol>
<li><p>
Verify that the [../www/changes.wiki | Change Log] is correct and
up-to-date.
</ol>
<hr>
Upon successful completion of all tests above, tag the release candidate
with the "release" tag and set its background color to "#d0c0ff". Update
the www/changes.wiki file to show the date of the release.

This file contains utf-16be text.
The purpose for including this file in the Fossil
repository is to provide the ability to test Fossil's
handling of UTF-16 using its own repository.
Browsing to this file in the web interface should display the file as
text on the screen.
When there are changes to this file those changes should show
up in the "diff" output and be properly displayed on the
screen.
Test procedures:
1. Verify that this file is correctly display using the /artifact
webpage.
2. Verify that this file is correctly displayed by the /doc webpage.
3. Verify that changes to are correctly displayed by the /fdiff webpage.
4. Verify that the "fossil diff" command correctly displays changes
in this file. Do the same with the --tk option.

# This is a TCL script that tries to sync the changes in a local
# Fossil checkout to another machine. The changes are gathered into
# a tarball, then sent via ssh to the remote and unpacked.
#
# Usage:
#
# co-rsync.tcl REMOTE
#
# Where REMOTE is the root of the remote repository into which changes
# are to be moved.
#
# Use Case:
#
# Sometimes while in the middle of an edit it is useful to transfer
# the incomplete changes to another machine for testing. This could
# be accomplished using scp, but doing it that was is tedious if many
# files in multiple directories have changed. This command does all
# the necessary transfer using a single command.
#
# A Tcl comment, whose contents don't matter \
exec tclsh "$0" "$@"
# Begin by changing directories to the root of the check-out.

*******************************************************************************
**
** This program reads Fossil source code files and tries to verify that
** printf-style format strings are correct.
**
** This program implements a compile-time validation step on the Fossil
** source code. Running this program is entirely optional. Its role is
** similar to the -Wall compiler switch on gcc, or the scan-build utility
** of clang, or other static analyzers. The purpose is to try to identify
** problems in the source code at compile-time. The difference is that this
** static checker is specifically designed for the particular printf formatter
** implementation used by Fossil.
**
** Checks include:
**
** * Verify that vararg formatting routines like blob_printf() or
** db_multi_exec() have the correct number of arguments for their
** format string.
**
** * For routines designed to generate SQL or HTML or a URL or JSON,
** detect and warn about possible injection attacks.

#!/usr/bin/env perl
# Fossil emulation of the "git log --patch / -p" feature: emit a stream
# of diffs from one version to the next for each file named on the
# command line.
#
# LIMITATIONS: It does not assume "all files" if you give no args, and
# it cannot take a directory to mean "all files under this parent".
#
# PREREQUISITES: This script needs several CPAN modules to run properly.
# There are multiple methods to install them:
#
# sudo dnf install perl-File-Which perl-IO-Interactive
# sudo apt install libfile-which-perl libio-interactive-perl
# sudo cpanm File::Which IO::Interactive
# ...etc...

** library scope The object is visible and usable within other

** a library, then the object is not visible to users
** of the library. (i.e. the object does not appear
** in the output when using the -H option.)
**
** EXPORT scope The object is visible and usable everywhere.
**
** The DP_Flag is a temporary use flag that is used during processing to
** prevent an infinite loop. It's use is localized.

<h2>1.0 Background</h2>
<p>
A piece of C source code can be one of two things:
a <em>declaration</em> or a <em>definition</em>.
A declaration is source text that gives information to the
compiler but doesn't directly result in any code being generated.
A definition is source text that results in executable machine
instructions or initialization data.
(These two terms are sometimes used inconsistently by other authors.
In particular, many people reverse the meanings of these words when
discussing Pascal or Ada code.
The meanings described here are the same as used in the ANSI-C
standards document.)
</p>
<p>
Declarations in C include things such as the following:
<ul>
<li> Typedefs.
<li> Structure, union and enumeration declarations.
<li> Function and procedure prototypes.
<li> Preprocessor macros and #defines.
<li> “<code>extern</code>” variable declarations.
</ul>
</p>
<p>
Definitions in C, on the other hand, include these kinds of things:
<ul>
<li> Variable definitions.
<li> The bodies of functions and procedures.
<li> Initialization data.
</ul>
</p>
<p>
The distinction between a declaration and a definition is common in
modern software engineering.
Another way of looking at the difference is that the declaration
is the <em>interface</em> and the definition is the <em>implementation</em>.
</p>
<p>
In C programs, it has always been the tradition that declarations are
put in files with the “<code>.h</code>” suffix and definitions are
placed in “<code>.c</code>” files.
The .c files contain “<code>#include</code>” preprocessor statements
that cause the contents of .h files to be included as part of the
source code when the .c file is compiled.
In this way, the .h files define the interface to a subsystem and
the .c files define how the subsystem is implemented.
</p>
<a name="H0003"></a>
<h3>1.1 Problems With The Traditional Approach</h3>
<p>
As the art of computer programming continues to advance, and the size
and complexity of programs continues to swell, the traditional C
approach of placing declarations and definitions in separate files begins
to present the programmer with logistics and
maintenance problems.
To wit:
</p>
<p>
<ol>
<p><li>
In large codes with many source files, it becomes difficult to determine
which .h files should be included in which .c files.
<p><li>
It is typically the case that a .h file will be forced to include
another .h files, which in turn might include other .h files,
and so forth.
The .c file must be recompiled when any of the .h files in this chain
are altered, but it can be difficult to determine what .h files are found
in the include chain.
A frequent Makefile error is to omit some .h files from a dependency
list even though those files are on the include file chain.
<p><li>
Some information is common to both the declaration and the definition of
an object in C, and so must be repeated in both the .h and the .c files
for that object.
In a large project, it can become increasingly difficult to keep the two
files in sync.
<p><li>
When a .c file includes a .h file and the .h files changes, the .c file
must be recompiled, even if the part of the .h file that changed is not
actually used by the .c file.
In a large program, it is generally the case that almost every .c file ends up
depending on one or two of the more important .h files, and so when those .h
files change, the entire program must be recompiled.
It also happens that those important .h files tend to be the ones that
change most frequently.
This means that the entire program must be recompiled frequently,
leading to a lengthy modify-compile-test cycle and a corresponding
decrease in programmer productivity.
<p><li>
The C programming language requires that declarations depending upon
each other must occur in a particular order.
In a program with complex, interwoven data structures, the correct
declaration order can become very difficult to determine manually,
especially when the declarations involved are spread out over several
files.
</ol>
</p>
<a name="H0004"></a>
<h3>1.2 The Makeheaders Solution</h3>
<p>
The makeheaders program is designed to ameliorate the problems associated
with the traditional C programming model by automatically generating
the interface information in the .h files from
interface information contained in other .h files and
from implementation information in the .c files.
When the makeheaders program is run, it scans the source
files for a project,
then generates a series of new .h files, one for each .c file.
The generated .h files contain exactly those declarations required by the
corresponding .c files, no more and no less.
</p>
<p>
The makeheaders programming model overcomes all of the objections to the
traditional C programming model.
<ol>
<p><li>
Because all declarations needed by a .c file are contained in a
single .h file, there is never any question about what .h files
a .c will need to include. If the .c file is named
<code>alpha.c</code> then it must include only the single .h file
named <code>alpha.h</code>.
(The .c file might also use some include files from the standard
library, such as <code><stdio.h></code>, but that is another matter.)
<p><li>
The generated .h files do not include other .h files, and so there
are no include chains to worry about.
The file <code>alpha.c</code> depends on <code>alpha.h</code> and
nothing more.
<p><li>
There is still duplication in the .h and the .c file, but because
the duplicate information is automatically generated, it is no longer
a problem.
Simply rerun makeheaders to resynchronize everything.
<p><li>
The generated .h file contains the minimal set of declarations needed
by the .c file.
This means that when something changes, a minimal amount of recompilation
is required to produce an updated executable.
Experience has shown that this gives a dramatic improvement
in programmer productivity by facilitating a rapid modify-compile-test
cycle during development.
<p><li>
The makeheaders program automatically sorts declarations into the
correct order, completely eliminating the wearisome and error-prone
task of sorting declarations by hand.
</ol>
<p>
<p>
In addition, the makeheaders program is fast and unintrusive.
It is a simple matter to incorporate makeheaders into a Makefile
so that makeheaders will be run automatically whenever the project
is rebuilt.
And the burden of running makeheaders is light.
It will easily process tens of thousands of lines of source
code per second.
</p>
<a name="H0005"></a>
<h2>2.0 Running The Makeheaders Program</h2>
<p>
The makeheaders program is very easy to run.
If you have a collection of C source code and include files in the working
directory, then you can run makeheaders to generate appropriate .h
files using the following command:
<pre>
makeheaders *.[ch]
</pre>
That's really all there is to it!
This command will generate one .h file for every .c file.
Any .h files that were generated by a prior run of makeheaders
are ignored,
but manually entered .h files
that contain structure declarations and so forth will be scanned and
the declarations will be copied into the generated .h files as
appropriate.
But if makeheaders sees that the .h file that it has generated is no
different from the .h file it generated last time, it doesn't update
the file.
This prevents the corresponding .c files from having to
be needlessly recompiled.
</p>
<p>
There are several options to the makeheaders program that can
be used to alter its behavior.
The default behavior is to write a single .h file for each .c file and
to give the .h file the same base name as the .c file.
Instead of generating a whole mess of .h files, you can, if you choose,
generate a single big .h file that contains all declarations needed
by all the .c files. Do this using the -h option to makeheaders.
As follows:
<pre>
makeheaders -h *.[ch] >common.h
</pre>
With the -h option, the .h file is not actually written to a disk file but
instead appears on standard output, where you are free to redirect it
into the file of your choice.
</p>
<p>
A similar option is -H. Like the lower-case -h option, big -H
generates a single include file on standard output. But unlike
small -h, the big -H only emits prototypes and declarations that
have been designated as “exportable”.
The idea is that -H will generate an include file that defines
the interface to a library.
More will be said about this in section 3.4.
</p>
<p>
Sometimes you want the base name of the .c file and the .h file to
be different.
For example, suppose you want the include file for <code>alpha.c</code>
to be called <code>beta.h</code>.
In this case, you would invoke makeheaders as follows:
<pre>
makeheaders alpha.c:beta.h
</pre>
Any time a filename argument contains a colon, the name before the
colon is taken to be the name of the .c file and the name after the
colon is taken to be the name of the .h file.
You can't use the shell's wildcard mechanism with this approach, but that
normally isn't a problem in Makefiles, which is where this stuff
comes in handy.
</p>
<p>
If you want a particular file to be scanned by makeheaders but you
don't want makeheaders to generate a header file for that file,
then you can supply an empty header filename, like this:
<pre>
makeheaders alpha.c beta.c gamma.c:
</pre>
In this example, makeheaders will scan the three files named
“<code>alpha.c</code>”,
“<code>beta.c</code>” and
“<code>gamma.c</code>”
but because of the colon on the end of third filename
it will only generate headers for the first two files.
Unfortunately,
it is not possible to get makeheaders to process any file whose
name contains a colon.
</p>
<p>
In a large project, the length of the command line for makeheaders
can become very long.
If the operating system doesn't support long command lines
(example: DOS and Win32) you may not be able to list all of the
input files in the space available.
In that case, you can use the “<code>-f</code>” option followed
by the name of a file to cause makeheaders to read command line
options and filename from the file instead of from the command line.
For example, you might prepare a file named “<code>mkhdr.dat</code>”
that contains text like this:
<pre>
src/alpha.c:hdr/alpha.h
src/beta.c:hdr/beta.h
src/gamma.c:hdr/gamma.h
...
</pre>
Then invoke makeheaders as follows:
<pre>
makeheaders -f mkhdr.dat
</pre>
</p>
<p>
The “<code>-local</code>” option causes makeheaders to
generate of prototypes for “<code>static</code>” functions and
procedures.
Such prototypes are normally omitted.
</p>
<p>
Finally, makeheaders also includes a “<code>-doc</code>” option.
This command line option prevents makeheaders from generating any
headers at all.
Instead, makeheaders will write to standard output
information about every definition and declaration that it encounters
in its scan of source files.
The information output includes the type of the definition or
declaration and any comment that precedes the definition or
declaration.
The output is in a format that can be easily parsed, and is
intended to be read by another program that will generate
documentation about the program.
We'll talk more about this feature later.
</p>
<p>
If you forget what command line options are available, or forget
their exact name, you can invoke makeheaders using an unknown
command line option (like “<code>--help</code>” or
“<code>-?</code>”)
and it will print a summary of the available options on standard
error.
If you need to process a file whose name begins with
“<code>-</code>”,
you can prepend a “<code>./</code>” to its name in order to get it
accepted by the command line parser.
Or, you can insert the special option “<code>--</code>” on the
command line to cause all subsequent command line arguments to be treated as
filenames even if their names begin with “<code>-</code>”.

<h2>3.0 Preparing Source Files For Use With Makeheaders</h2>
<p>
Very little has to be done to prepare source files for use with
makeheaders since makeheaders will read and understand ordinary
C code.
But it is important that you structure your files in a way that
makes sense in the makeheaders context.
This section will describe several typical uses of makeheaders.
</p>
<a name="H0007"></a>
<h3>3.1 The Basic Setup</h3>
<p>
The simplest way to use makeheaders is to put all definitions in
one or more .c files and all structure and type declarations in
separate .h files.
The only restriction is that you should take care to chose basenames
for your .h files that are different from the basenames for your
.c files.
Recall that if your .c file is named (for example)
“<code>alpha.c</code>”
makeheaders will attempt to generate a corresponding header file
named “<code>alpha.h</code>”.
For that reason, you don't want to use that name for
any of the .h files you write since that will prevent makeheaders
from generating the .h file automatically.
</p>
<p>
The structure of a .c file intended for use with makeheaders is very
simple.
All you have to do is add a single “<code>#include</code>” to the
top of the file that sources the header file that makeheaders will generate.
Hence, the beginning of a source file named “<code>alpha.c</code>”
might look something like this:
</p>
<pre>
/*
* Introductory comment...
*/
#include "alpha.h"
/* The rest of your code... */
</pre>
<p>
Your manually generated header files require no special attention at all.
Code them as you normally would.
However, makeheaders will work better if you omit the
“<code>#if</code>” statements people often put around the outside of
header files that prevent the files from being included more than once.
For example, to create a header file named “<code>beta.h</code>”,
many people will habitually write the following:
<pre>
#ifndef BETA_H
#define BETA_H
/* declarations for beta.h go here */
#endif
</pre>
You can forego this cleverness with makeheaders.
Remember that the header files you write will never really be
included by any C code.
Instead, makeheaders will scan your header files to extract only
those declarations that are needed by individual .c files and then
copy those declarations to the .h files corresponding to the .c files.
Hence, the “<code>#if</code>” wrapper serves no useful purpose.
But it does make makeheaders work harder, forcing it to put
the statements
<pre>
#if !defined(BETA_H)
#endif
</pre>
around every declaration that it copies out of your header file.
No ill effect should come of this, but neither is there any benefit.
</p>
<p>
Having prepared your .c and .h files as described above, you can
cause makeheaders to generate its .h files using the following simple
command:
<pre>
makeheaders *.[ch]
</pre>
The makeheaders program will scan all of the .c files and all of the
manually written .h files and then automatically generate .h files
corresponding to all .c files.
</p>
<p>
Note that
the wildcard expression used in the above example,
“<code>*.[ch]</code>”,
will expand to include all .h files in the current directory, both
those entered manually be the programmer and others generated automatically
by a prior run of makeheaders.
But that is not a problem.
The makeheaders program will recognize and ignore any files it
has previously generated that show up on its input list.
</p>
<a name="H0008"></a>
<h3>3.2 What Declarations Get Copied</h3>
<p>
The following list details all of the code constructs that makeheaders
will extract and place in
the automatically generated .h files:
</p>
<ul>
<p><li>
When a function is defined in any .c file, a prototype of that function
is placed in the generated .h file of every .c file that
calls the function.</p>
<P>If the “<code>static</code>” keyword of C appears at the
beginning of the function definition, the prototype is suppressed.
If you use the “<code>LOCAL</code>” keyword where you would normally
say “<code>static</code>”, then a prototype is generated, but it
will only appear in the single header file that corresponds to the
source file containing the function. For example, if the file
<code>alpha.c</code> contains the following:
<pre>
LOCAL int testFunc(void){
return 0;
}
</pre>
Then the header file <code>alpha.h</code> will contain
<pre>
#define LOCAL static
LOCAL int testFunc(void);
</pre>
However, no other generated header files will contain a prototype for
<code>testFunc()</code> since the function has only file scope.</p>
<p>When the “<code>LOCAL</code>” keyword is used, makeheaders will
also generate a #define for LOCAL, like this:
<pre>
#define LOCAL static
</pre>
so that the C compiler will know what it means.</p>
<p>If you invoke makeheaders with a “<code>-local</code>”
command-line option, then it treats the “<code>static</code>”
keyword like “<code>LOCAL</code>” and generates prototypes in the
header file that corresponds to the source file containing the function
definition.</p>
<p><li>
When a global variable is defined in a .c file, an
“<code>extern</code>”
declaration of that variable is placed in the header of every
.c file that uses the variable.
</p>
<p><li>
When a structure, union or enumeration declaration or a
function prototype or a C++ class declaration appears in a
manually produced .h file, that declaration is copied into the
automatically generated
.h files of all .c files that use the structure, union, enumeration,
function or class.
But declarations that appear in a
.c file are considered private to that .c file and are not copied into
any automatically generated files.
</p>
<p><li>
All #defines and typedefs that appear in manually produced .h files
are copied into automatically generated .h files as needed.
Similar constructs that appear in .c files are considered private to
those files and are not copied.
</p>
<p><li>
When a structure, union or enumeration declaration appears in a .h
file, makeheaders will automatically
generate a typedef that allows the declaration to be referenced without
the “<code>struct</code>”, “<code>union</code>” or
“<code>enum</code>” qualifier.
In other words, if makeheaders sees the code:
<pre>
struct Examp { /* ... */ };
</pre>
it will automatically generate a corresponding typedef like this:
<pre>
typedef struct Examp Examp;
</pre>
</p>
<p><li>
Makeheaders generates an error message if it encounters a function or
variable definition within a .h file.
The .h files are supposed to contain only interface, not implementation.
C compilers will not enforce this convention, but makeheaders does.
</ul>
<p>
As a final note, we observe that automatically generated declarations
are ordered as required by the ANSI-C programming language.
If the declaration of some structure “<code>X</code>” requires a
prior declaration of another structure “<code>Y</code>”, then Y will
appear first in the generated headers.
</p>
<a name="H0009"></a>
<h3>3.3 How To Avoid Having To Write Any Header Files</h3>
<p>
In my experience, large projects work better if all of the manually
written code is placed in .c files and all .h files are generated
automatically.
This is slightly different from the traditional C method of placing
the interface in .h files and the implementation in .c files, but
it is a refreshing change that brings a noticeable improvement to the
coding experience.
Others, I believe, share this view since I've
noticed recent languages (ex: java, tcl, perl, awk) tend to
support the one-file approach to coding as the only option.
</p>
<p>
The makeheaders program supports putting both
interface and implementation into the same source file.
But you do have to tell makeheaders which part of the source file is the
interface and which part is the implementation.
Makeheaders has to know this in order to be able to figure out whether or
not structures declarations, typedefs, #defines and so forth should
be copied into the generated headers of other source files.
</p>
<p>
You can instruct makeheaders to treat any part of a .c file as if
it were a .h file by enclosing that part of the .c file within:
<pre>
#if INTERFACE
#endif
</pre>
Thus any structure definitions that appear after the
“<code>#if INTERFACE</code>” but before the corresponding
“<code>#endif</code>” are eligible to be copied into the
automatically generated
.h files of other .c files.
</p>
<p>
If you use the “<code>#if INTERFACE</code>” mechanism in a .c file,
then the generated header for that .c file will contain a line
like this:
<pre>
#define INTERFACE 0
</pre>
In other words, the C compiler will never see any of the text that
defines the interface.
But makeheaders will copy all necessary definitions and declarations
into the .h file it generates, so .c files will compile as if the
declarations were really there.
This approach has the advantage that you don't have to worry with
putting the declarations in the correct ANSI-C order -- makeheaders
will do that for you automatically.
</p>
<p>
Note that you don't have to use this approach exclusively.
You can put some declarations in .h files and others within the
“<code>#if INTERFACE</code>” regions of .c files.
Makeheaders treats all declarations alike, no matter where they
come from.
You should also note that a single .c file can contain as many
“<code>#if INTERFACE</code>” regions as desired.
</p>
<a name="H0010"></a>
<h3>3.4 Designating Declarations For Export</h3>
<p>
In a large project, one will often construct a hierarchy of
interfaces.
For example, you may have a group of 20 or so files that form
a library used in several other parts of the system.
Each file in this library will present two interfaces.
One interface will be the routines and data structures it is
willing to share with other files in the same library, and the
second interface is those routines and data structures it wishes
to make available to other subsystems.
(The second interface is normally a subset of the first.)
Ordinary C does not provide support for a tiered interface
like this, but makeheaders does.
</p>
<p>
Using makeheaders, it is possible to designate routines and data
structures as being for “<code>export</code>”.
Exported objects are visible not only to other files within the
same library or subassembly but also to other
libraries and subassemblies in the larger program.
By default, makeheaders only makes objects visible to other members
of the same library.
</p>
<p>
That isn't the complete truth, actually.
The semantics of C are such that once an object becomes visible
outside of a single source file, it is also visible to any user
of the library that is made from the source file.
Makeheaders can not prevent outsiders from using non-exported resources,
but it can discourage the practice by refusing to provide prototypes
and declarations for the services it does not want to export.
Thus the only real effect of the making an object exportable is
to include it in the output makeheaders generates when it is run
using the -H command line option.
This is not a perfect solution, but it works well in practice.
</p>
<p>
But trouble quickly arises when we attempt to devise a mechanism for
telling makeheaders which prototypes it should export and which it should
keep local.
The built-in “<code>static</code>” keyword of C works well for
prohibiting prototypes from leaving a single source file, but because C doesn't
support a linkage hierarchy, there is nothing in the C language to help us.
We'll have to invite our own keyword: “<code>EXPORT</code>”
</p>
<p>
Makeheaders allows the EXPORT keyword to precede any function or
procedure definition.
The routine following the EXPORT keyword is then eligable to appear
in the header file generated using the -H command line option.
Note that if a .c file contains the EXPORT keyword, makeheaders will
put the macro
<pre>
#define EXPORT
</pre>
in the header file it generates for the .c file so that the EXPORT keyword
will never be seen by the C compiler.
</p>
<p>
But the EXPORT keyword only works for function and procedure definitions.
For structure, union and enum definitions, typedefs, #defines and
class declarations, a second mechanism is used.
Just as any declarations or definition contained within
<pre>
#if INTERFACE
#endif
</pre>
are visible to all files within the library, any declarations
or definitions within
<pre>
#if EXPORT_INTERFACE
#endif
</pre>
will become part of the exported interface.
The “<code>#if EXPORT_INTERFACE</code>” mechanism can be used in
either .c or .h files.
(The “<code>#if INTERFACE</code>” can also be used in both .h and
.c files, but since it's use in a .h file would be redundant, we haven't
mentioned it before.)
</p>

<h3>3.5 Local declarations processed by makeheaders</h3>
<p>
Structure declarations and typedefs that appear in .c files are normally
ignored by makeheaders.
Such declarations are only intended for use by the source file in which
they appear and so makeheaders doesn't need to copy them into any
generated header files.
We call such declarations “<code>private</code>”.
</p>
<p>
Sometimes it is convenient to have makeheaders sort a sequence
of private declarations into the correct order for us automatically.
Or, we could have static functions and procedures for which we would like
makeheaders to generate prototypes, but the arguments to these
functions and procedures uses private declarations.
In both of these cases, we want makeheaders to be aware of the
private declarations and copy them into the local header file,
but we don't want makeheaders to propagate the
declarations outside of the file in which they are declared.
</p>
<p>
When this situation arises, enclose the private declarations
within
<pre>
#if LOCAL_INTERFACE
#endif
</pre>
A “<code>LOCAL_INTERFACE</code>” block works very much like the
“<code>INTERFACE</code>” and
“<code>EXPORT_INTERFACE</code>”
blocks described above, except that makeheaders insures that the
objects declared in a LOCAL_INTERFACE are only visible to the
file containing the LOCAL_INTERFACE.
</p>

<h3>3.6 Using Makeheaders With C++ Code</h3>
<p>
You can use makeheaders to generate header files for C++ code, in
addition to C.
Makeheaders will recognize and copy both “<code>class</code>”
declarations
and inline function definitions, and it knows not to try to generate
prototypes for methods.
</p>
<p>
In fact, makeheaders is smart enough to be used in projects that employ
a mixture of C and C++.
For example, if a C function is called from within a C++ code module,
makeheaders will know to prepend the text
<pre>
extern "C"
</pre>
to the prototype for that function in the C++ header file.
Going the other way,
if you try to call a C++ function from within C, an
appropriate error message is issued, since C++ routines can not
normally be called by C code (due to fact that most C++ compilers
use name mangling to facilitate type-safe linkage.)
</p>
<p>
No special command-line options are required to use makeheaders with
C++ input. Makeheaders will recognize that its source code is C++
by the suffix on the source code filename. Simple ".c" or ".h" suffixes
are assumed to be ANSI-C. Anything else, including ".cc", ".C" and
".cpp" is assumed to be C++.
The name of the header file generated by makeheaders is derived from
the name of the source file by converting every "c" to "h" and
every "C" to "H" in the suffix of the filename.
Thus the C++ source
file “<code>alpha.cpp</code>” will induce makeheaders to
generate a header file named “<code>alpha.hpp</code>”.
</p>
<p>
Makeheaders augments class definitions by inserting prototypes to
methods where appropriate. If a method definition begins with one
of the special keywords <b>PUBLIC</b>, <b>PROTECTED</b>, or
<b>PRIVATE</b> (in upper-case to distinguish them from the regular
C++ keywords with the same meaning) then a prototype for that
method will be inserted into the class definition. If none of
these keywords appear, then the prototype is not inserted. For
example, in the following code, the constructor is not explicitly
declared in the class definition but makeheaders will add it there
because of the PUBLIC keyword that appears before the constructor
definition.
</p>
<blockquote><pre>
#if INTERFACE
class Example1 {
private:
int v1;
};
#endif
PUBLIC Example1::Example1(){
v1 = 0;
}
</pre></blockquote>
<p>
The code above is equivalent to the following:
</p>
<blockquote><pre>
#if INTERFACE
class Example1 {
private:
int v1;
public:
Example1();
};
#endif
Example1::Example1(){
v1 = 0;
}
</pre></blockquote>
<p>
The first form is preferred because only a single declaration of
the constructor is required. The second form requires two declarations,
one in the class definition and one on the definition of the constructor.
</p>
<h4>3.6.1 C++ Limitations</h4>
<p>
Makeheaders does not understand more recent
C++ syntax such as templates and namespaces.
Perhaps these issues will be addressed in future revisions.
</p>
<a name="H0013"></a>
<h3>3.7 Conditional Compilation</h3>
<p>
The makeheaders program understands and tracks the conditional
compilation constructs in the source code files it scans.
Hence, if the following code appears in a source file
<pre>
#ifdef UNIX
# define WORKS_WELL 1
#else
# define WORKS_WELL 0
#endif
</pre>
then the next patch of code will appear in the generated header for
every .c file that uses the WORKS_WELL constant:
<pre>
#if defined(UNIX)
# define WORKS_WELL 1
#endif
#if !defined(UNIX)
# define WORKS_WELL 0
#endif
</pre>
The conditional compilation constructs can be nested to any depth.
Makeheaders also recognizes the special case of
<pre>
#if 0
#endif
</pre>
and treats the enclosed text as a comment.
</p>
<a name="H0014"></a>
<h3>3.8 Caveats</h3>
<p>
The makeheaders system is designed to be robust
but it is possible for a devious programmer to fool the system,
usually with unhelpful consequences.
This subsection is a guide to helping you avoid trouble.
</p>
<p>
Makeheaders does not understand the old K&R style of function
and procedure definitions.
It only understands the modern ANSI-C style, and will probably
become very confused if it encounters an old K&R function.
Therefore you should take care to avoid putting K&R function definitions
in your code.
</p>
<p>
Makeheaders does not understand when you define more than one
global variable with the same type separated by a comma.
In other words, makeheaders does not understand this:
<pre>
int a = 4, b = 5;
</pre>
The makeheaders program wants every variable to have its own
definition. Like this:
<pre>
int a = 4;
int b = 5;
</pre>
Notice that this applies to global variables only, not to variables
you declare inside your functions.
Since global variables ought to be exceedingly rare, and since it is
good style to declare them separately anyhow, this restriction is
not seen as a terrible hardship.
</p>
<p>
Makeheaders does not support defining an enumerated or aggregate type in
the same statement as a variable declaration. None of the following
statements work completely:
<pre>
struct {int field;} a;
struct Tag {int field;} b;
struct Tag c;
</pre>
Instead, define types separately from variables:
<pre>
#if INTERFACE
struct Tag {int field;};
#endif
Tag a;
Tag b; /* No more than one variable per declaration. */
Tag c; /* So must put each on its own line. */
</pre>
See <a href="#H0008">3.2 What Declarations Get Copied</a> for details,
including on the automatic typedef.
</p>
<p>
The makeheaders program processes its source file prior to sending
those files through the C preprocessor.
Hence, if you hide important structure information in preprocessor defines,
makeheaders might not be able to successfully extract the information
it needs from variables, functions and procedure definitions.
For example, if you write this:
<pre>
#define BEGIN {
#define END }
</pre>
at the beginning of your source file, and then try to create a function
definition like this:
<pre>
char *StrDup(const char *zSrc)
BEGIN
/* Code here */
END
</pre>
then makeheaders won't be able to find the end of the function definition
and bad things are likely to happen.
</p>
<p>
For most projects the code constructs that makeheaders cannot
handle are very rare.
As long as you avoid excessive cleverness, makeheaders will
probably be able to figure out what you want and will do the right
thing.
</p>
<p>
Makeheaders has limited understanding of enums. In particular, it does
not realize the significance of enumerated values, so the enum is not
emitted in the header files when its enumerated values are used unless
the name associated with the enum is also used. Moreover, enums can be
completely anonymous, e.g. “<code>enum {X, Y, Z};</code>”.
Makeheaders ignores such enums so they can at least be used within a
single source file. Makeheaders expects you to use #define constants
instead. If you want enum features that #define lacks, and you need the
enum in the interface, bypass makeheaders and write a header file by
hand, or teach makeheaders to emit the enum definition when any of the
enumerated values are used, rather than only when the top-level name (if
any) is used.

<h2>4.0 Using Makeheaders To Generate Documentation</h2>
<p>
Many people have observed the advantages of generating program
documentation directly from the source code:
<ul>
<li> Less effort is involved. It is easier to write a program than
it is to write a program and a document.
<li> The documentation is more likely to agree with the code.
When documentation is derived directly from the code, or is
contained in comments immediately adjacent to the code, it is much
more likely to be correct than if it is contained in a separate
unrelated file in a different part of the source tree.
<li> Information is kept in only one place. When a change occurs
in the code, it is not necessary to make a corresponding change
in a separate document. Just rerun the documentation generator.
</ul>
The makeheaders program does not generate program documentation itself.
But you can use makeheaders to parse the program source code, extract
the information that is relevant to the documentation and to pass this
information to another tool to do the actual documentation preparation.
</p>
<p>
When makeheaders is run with the “<code>-doc</code>” option, it
emits no header files at all.
Instead, it does a complete dump of its internal tables to standard
output in a form that is easily parsed.
This output can then be used by another program (the implementation
of which is left as an exercise to the reader) that will use the
information to prepare suitable documentation.
</p>
<p>
The “<code>-doc</code>” option causes makeheaders to print
information to standard output about all of the following objects:
<ul>
<li> C++ class declarations
<li> Structure and union declarations
<li> Enumerations
<li> Typedefs
<li> Procedure and function definitions
<li> Global variables
<li> Preprocessor macros (ex: “<code>#define</code>”)
</ul>
For each of these objects, the following information is output:
<ul>
<li> The name of the object.
<li> The type of the object. (Structure, typedef, macro, etc.)
<li> Flags to indicate if the declaration is exported (contained within
an EXPORT_INTERFACE block) or local (contained with LOCAL_INTERFACE).
<li> A flag to indicate if the object is declared in a C++ file.
<li> The name of the file in which the object was declared.
<li> The complete text of any block comment that precedes the declarations.
<li> If the declaration occurred inside a preprocessor conditional
(“<code>#if</code>”) then the text of that conditional is
provided.
<li> The complete text of a declaration for the object.
</ul>
The exact output format will not be described here.
It is simple to understand and parse and should be obvious to
anyone who inspects some sample output.

<h2>5.0 Compiling The Makeheaders Program</h2>
<p>
The source code for makeheaders is a single file of ANSI-C code,
approximately 3000 lines in length.
The program makes only modest demands of the system and C library
and should compile without alteration on most ANSI C compilers
and on most operating systems.
It is known to compile using several variations of GCC for Unix
as well as Cygwin32 and MSVC 5.0 for Win32.
</p>
<a name="H0017"></a>
<h2>6.0 History</h2>
<p>
The makeheaders program was first written by D. Richard Hipp
(also the original author of
<a href="https://sqlite.org/">SQLite</a> and
<a href="https://fossil-scm.org/">Fossil</a>) in 1993.
Hipp open-sourced the project immediately, but it never caught
on with any other developers and it continued to be used mostly
by Hipp himself for over a decade. When Hipp was first writing
the Fossil version control system in 2006 and 2007, he used
makeheaders on that project to help simplify the source code.
As the popularity of Fossil increased, the makeheaders
that was incorporated into the Fossil source tree became the
"official" makeheaders implementation.
</p>
<p>
As this paragraph is being composed (2016-11-05), Fossil is the
only project known to Hipp that is still using makeheaders. On
the other hand, makeheaders has served the Fossil project well and
there are no plans remove it.
</p>
<a name="H0018"></a>
<h2>7.0 Summary And Conclusion</h2>
<p>
The makeheaders program will automatically generate a minimal header file
for each of a set of C source and header files, and will
generate a composite header file for the entire source file suite,
for either internal or external use.
It can also be used as the parser in an automated program
documentation system.
</p>
<p>
The makeheaders program has been in use since 1994,
in a wide variety of projects under both UNIX and Win32.
In every project where it has been used, makeheaders has proven
to be a very helpful aid
in the construction and maintenance of large C codes.
In at least two cases, makeheaders has facilitated development
of programs that would have otherwise been all but impossible
due to their size and complexity.

# ### Run this Tcl script EVERY time you modify it in any way! ###
# ### It must be run from the directory it lives in so that ###
# ### directories resolve properly! ###
#
# This Tcl script generates make files for various platforms. The makefiles
# then need to be committed.
#
# If you modify this file then:
#
# 1. cd tools; tclsh makemake.tcl
#
# 2. if errors are reported, fix them and go to step 1
#
# 3. if "fossil diff" reports changes in any of the generated
# files, commit the changed files to the repo
#
# Files generated include:
#
# src/main.mk # makefile for all unix systems
# win/Makefile.mingw # makefile for mingw on windows
# win/Makefile.* # makefiles for other windows compilers
#
# Add new source files by listing the files (without their .c suffix)
# in the "src" variable. Add new resource files to the "extra_files"
# variable. There are other variables that you can alter, down to
# the "STOP HERE" comment. The stuff below "STOP HERE" should rarely need
# to change. After modification, go to step 1 above.
#
# Delete unused source files in the "src" variable, then go to step 1 above.

# If the build stops here, or if the custom linker flags are outside the scope
# of `editbin` or `link /EDIT` (i.e. additional libraries), consider tweaking

** This is a stand-alone utility program that is part of the Fossil build
** process. This program reads files named on the command line and converts
** them into ANSI-C static char array variables. Output is written onto
** standard output.
**
** Additionally, the input files may be listed in a separate list file (one
** resource name per line, optionally enclosed in double quotes). Pass the list
** via '--reslist <the-list-file>' option. Both lists, from the command line and
** the list file, are merged; duplicate file names skipped from processing.
** This option is useful to get around the command line length limitations
** under some OS, like Windows.
**
** The makefiles use this utility to package various resources (large scripts,
** GIF images, etc) that are separate files in the source code as byte
** arrays in the resulting executable.

*******************************************************************************
**
** This utility program scans Fossil source text looking for specially
** formatted comments and generates C source code for constant tables
** that define the behavior of commands, webpages, and settings.
**
** The source code is scanned for comment lines of the form:
**
** WEBPAGE: /abc/xyz
** COMMAND: cmdname
** SETTING: access-log
**
** The WEBPAGE and COMMAND comments should be followed by a function that
** implements the webpage or command. The form of this function is:
**
** void function_name(void){
**
** Command names can divided into three classes: 1st-tier, 2nd-tier,
** and test. 1st-tier commands are the most frequently used and the
** ones that show up with "fossil help". 2nd-tier are seldom-used and/or
** legacy commands. Test commands are unsupported commands used for testing
** and analysis only.
**
** Commands are 1st-tier by default. If the command name begins with
** "test-" or if the command name has a "test" argument, then it becomes
** a test command. If the command name has a "2nd-tier" argument or ends
** with a "*" character, it is second tier. If the command name has an "alias"
** argument or ends with a "#" character, it is an alias: another name
** (a one-to-one replacement) for a command. Examples:
**
** COMMAND: abcde*
** COMMAND: fghij 2nd-tier
** COMMAND: mnopq#
** COMMAND: rstuv alias
** COMMAND: test-xyzzy
** COMMAND: xyzzy test
**
** A SETTING: may be followed by arguments that give additional attributes
** to that setting:
**
** SETTING: clean-blob versionable width=40 block-text
** SETTING: auto-shun boolean default=on
**
** New arguments may be added in future releases that set additional
** bits in the eCmdFlags field.
**
** Additional lines of comment after the COMMAND: or WEBPAGE: or SETTING:
** become the built-in help text for that command or webpage or setting.
** Backslashes must be escaped ("\\" in comment yields "\" in the help text.)
**
** Multiple COMMAND: entries can be attached to the same command, thus
** creating multiple aliases for that command. Similarly, multiple
** WEBPAGE: entries can be attached to the same webpage function, to give
** that page aliases.
**
** For SETTING: entries, the default value for the setting can be specified
** using a default=VALUE argument if the default contains no spaces. If the
** default value does contain spaces, use a separate line like this:
**
** SETTING: pgp-command
** DEFAULT: gpg --clearsign -o
**
** If no default is supplied, the default is assumed to be an empty string
** or "off" in the case of a boolean.

/*
** This C program generates the "VERSION.h" header file from information
** extracted out of the "manifest", "manifest.uuid", and "VERSION" files.
** Call this program with three arguments:
**
** ./a.out manifest.uuid manifest VERSION
**
** Note that the manifest.uuid and manifest files are generated by Fossil.
**
** The output becomes the "VERSION.h" file. The output is a C-language
** header that contains #defines for various properties of the build:
**
** MANIFEST_UUID These values are text strings that
** MANIFEST_VERSION identify the Fossil check-in to which
** the source tree belongs. They do not
** take into account any uncommitted edits.
**
** FOSSIL_BUILD_HASH A hexadecimal string that is a strong hash
** of the MANIFEST_UUID together with the
** current time of the build. We normally want
** this to be different on each build, as the
** value is used to expire ETag: fields in
** HTTP requests. But if you need to do
** repeatable byte-for-byte identical builds,
** add the -DFOSSIL_BUILD_EPOCH=n option.
**
** MANIFEST_DATE The date/time of the source-code check-in
** MANIFEST_YEAR in various formats.
** MANIFEST_NUMERIC_DATE
** MANIFEST_NUMERIC_TIME
**
** RELEASE_VERSION The version number (from the VERSION source
** RELEASE_VERSION_NUMBER file) in various format.
** RELEASE_RESOURCE_VERSION
**
** New #defines may be added in the future.

*******************************************************************************
**
** This file is NOT part of the Fossil executable. It is called from
** auto.def in the autosetup system.
**
** This file contains a test program used by ../configure with the
** the --disable-internal-sqlite option to determine whether or
** not the system SQLite library is sufficient to support Fossil.
**
** This must be compiled with -D MINIMUM_SQLITE_VERSION set in auto.def.
**
** It is preferred to statically link Fossil with the sqlite3.c source
** file that is part of the source tree and not use any SQLite shared
** library that is included with the system. But some packagers do not
** like to do this. Hence, we provide the option to link Fossil against
** the system SQLite shared library. But Fossil is very particular about
** the version and build options for SQLite. Unless a recent version of
** SQLite is available, and unless that SQLite is built using some
** non-default features, the system library won't meet the needs of
** Fossil. This program attempts to determine if the system library
** SQLite is sufficient for Fossil.
**
** Compile this program, linking it against the system SQLite library,
** and run it. If it returns with a zero exit code, then all is well.
** But if it returns a non-zero exit code, then the system SQLite library
** lacks some capability that Fossil uses. A message on stdout describes
** the missing feature.

*******************************************************************************
**
** SYNOPSIS:
**
** Input lines that begin with the "@" character are translated into
** either cgi_printf() statements or string literals and the
** translated code is written on standard output.
**
** The problem this program is attempt to solve is as follows: When
** writing CGI programs in C, we typically want to output a lot of HTML
** text to standard output. In pure C code, this involves doing a
** printf() with a big string containing all that text. But we have
** to insert special codes (ex: \n and \") for many common characters,
** which interferes with the readability of the HTML.
**
** This tool allows us to put raw HTML, without the special codes, in
** the middle of a C program. This program then translates the text
** into standard C by inserting all necessary backslashes and other
** punctuation.
**
** Enhancement #1:
**
** If the last non-whitespace character prior to the first "@" of a
** @-block is "=" or "," then the @-block is a string literal initializer
** rather than text that is to be output via cgi_printf(). Render it
** as such.
**
** Enhancement #2:
**
** Comments of the form: "|* @-comment: CC" (where "|" is really "/")
** cause CC to become a comment character for the @-substitution.
** Typical values for CC are "--" (for SQL text) or "#" (for Tcl script)
** or "//" (for C++ code). Lines of subsequent @-blocks that begin with
** CC are omitted from the output.
**
** Enhancement #3:
**
** If a non-enhancement #1 line ends in backslash, the backslash and the
** newline (\n) are not included in the argument to cgi_printf(). This
** is used to split one long output line across multiple source lines.

# NOTE: Appending custom linker flags to the OpenSSL default linker flags is
# somewhat difficult, as summarized in this Fossil Forum post:
#
# https://fossil-scm.org/forum/forumpost/a9a2d6af28b
#
# Therefore the custom linker flags required for Windows XP dynamic builds are
# applied in a separate post-build step.
#
# If the build stops here, or if the custom linker flags are outside the scope
# of `editbin` or `link /EDIT` (i.e. additional libraries), consider tweaking
# the OpenSSL makefile by hand.
#
# Also note that this step changes the subsystem for the OpenSSL DLLs from
# WINDOWS to CONSOLE, but which has no effect on DLLs.

<title>How CGI Works In Fossil</title>
<h2>Introduction</h2>
CGI or "Common Gateway Interface" is a venerable yet reliable technique for
generating dynamic web content. This article gives a quick background on how
CGI works and describes how Fossil can act as a CGI service.
This is a "how it works" guide. This document provides background
information on the CGI protocol so that you can better understand what
is going on behind the scenes. If you just want to set up Fossil
as a CGI server, see the [./server/ | Fossil Server Setup] page. Or
if you want to develop CGI-based extensions to Fossil, see
the [./serverext.wiki|CGI Server Extensions] page.
<h2>A Quick Review Of CGI</h2>
An HTTP request is a block of text that is sent by a client application
(usually a web browser) and arrives at the web server over a network
connection. The HTTP request contains a URL that describes the information
being requested. The URL in the HTTP request is typically the same URL
that appears in the URL bar at the top of the web browser that is making
the request. The URL might contain a "?" character followed by
query parameters. The HTTP will usually also contain other information
such as the name of the application that made the request, whether or
not the requesting application can accept a compressed reply, POST
parameters from forms, and so forth.
The job of the web server is to interpret the HTTP request and formulate
an appropriate reply.
The web server is free to interpret the HTTP request in any way it wants,
but most web servers follow a similar pattern, described below.
(Note: details may vary from one web server to another.)
Suppose the filename component of the URL in the HTTP request looks like this:
<pre>/one/two/timeline/four</pre>
Most web servers will search their content area for files that match
some prefix of the URL. The search starts with <b>/one</b>, then goes to
<b>/one/two</b>, then <b>/one/two/timeline</b>, and finally
<b>/one/two/timeline/four</b> is checked. The search stops at the first
match.
Suppose the first match is <b>/one/two</b>. If <b>/one/two</b> is an
ordinary file in the content area, then that file is returned as static
content. The "<b>/timeline/four</b>" suffix is silently ignored.
If <b>/one/two</b> is a CGI script (or program), then the web server
executes the <b>/one/two</b> script. The output generated by
the script is collected and repackaged as the HTTP reply.
Before executing the CGI script, the web server will set up various
environment variables with information useful to the CGI script:
<table>
<tr><th>Variable<th>Meaning
<tr><td>GATEWAY_INTERFACE<td>Always set to "CGI/1.0"
<tr><td>REQUEST_URI
<td>The input URL from the HTTP request.
<tr><td>SCRIPT_NAME
<td>The prefix of the input URL that matches the CGI script name.
In this example: "/one/two".
<tr><td>PATH_INFO
<td>The suffix of the URL beyond the name of the CGI script.
In this example: "timeline/four".
<tr><td>QUERY_STRING
<td>The query string that follows the "?" in the URL, if there is one.
</table>
There are other CGI environment variables beyond those listed above.
Many Fossil servers implement the
[https://fossil-scm.org/home/test_env/two/three?abc=xyz|test_env]
webpage that shows some of the CGI environment
variables that Fossil pays attention to.
In addition to setting various CGI environment variables, if the HTTP
request contains POST content, then the web server relays the POST content
to standard input of the CGI script.
In summary, the task of the
CGI script is to read the various CGI environment variables and
the POST content on standard input (if any), figure out an appropriate
reply, then write that reply on standard output.
The web server will read the output from the CGI script, reformat it
into an appropriate HTTP reply, and relay the result back to the
requesting application.
The CGI script exits as soon as it generates a single reply.
The web server will (usually) persist and handle multiple HTTP requests,
but a CGI script handles just one HTTP request and then exits.
The above is a rough outline of how CGI works.
There are many details omitted from this brief discussion.
See other on-line CGI tutorials for further information.
<h2>How Fossil Acts As A CGI Program</h2>
An appropriate CGI script for running Fossil will look something
like the following:
<pre>
#!/usr/bin/fossil
repository: /home/www/repos/project.fossil
</pre>
The first line of the script is a
"[https://en.wikipedia.org/wiki/Shebang_%28Unix%29|shebang]"
that tells the operating system what program to use as the interpreter
for this script. On unix, when you execute a script that starts with
a shebang, the operating system runs the program identified by the
shebang with a single argument that is the full pathname of the script
itself.
In our example, the interpreter is Fossil, and the argument might
be something like "/var/www/cgi-bin/one/two" (depending on how your
particular web server is configured).
The Fossil program that is run as the script interpreter
is the same Fossil that runs when
you type ordinary Fossil commands like "fossil sync" or "fossil commit".
But in this case, as soon as it launches, the Fossil program
recognizes that the GATEWAY_INTERFACE environment variable is
set to "CGI/1.0" and it therefore knows that it is being used as
CGI rather than as an ordinary command-line tool, and behaves accordingly.
When Fossil recognizes that it is being run as CGI, it opens and reads
the file identified by its sole argument (the file named by
<code>argv[1]</code>). In our example, the second line of that file
tells Fossil the location of the repository it will be serving.
Fossil then starts looking at the CGI environment variables to figure
out what web page is being requested, generates that one web page,
then exits.
Usually, the webpage being requested is the first term of the
PATH_INFO environment variable. (Exceptions to this rule are noted
in the sequel.) For our example, the first term of PATH_INFO
is "timeline", which means that Fossil will generate
the [/help?cmd=/timeline|/timeline] webpage.
With Fossil, terms of PATH_INFO beyond the webpage name are converted into
the "name" query parameter. Hence, the following two URLs mean
exactly the same thing to Fossil:
<ol type='A'>
<li> [https://fossil-scm.org/home/info/c14ecc43]
<li> [https://fossil-scm.org/home/info?name=c14ecc43]
</ol>
In both cases, the CGI script is called "/fossil". For case (A),
the PATH_INFO variable will be "info/c14ecc43" and so the
"[/help?cmd=/info|/info]" webpage will be generated and the suffix of
PATH_INFO will be converted into the "name" query parameter, which
identifies the artifact about which information is requested.
In case (B), the PATH_INFO is just "info", but the same "name"
query parameter is set explicitly by the URL itself.
<h2>Serving Multiple Fossil Repositories From One CGI Script</h2>
The previous example showed how to serve a single Fossil repository
using a single CGI script.
On a website that wants to serve multiple repositories, one could
simply create multiple CGI scripts, one script for each repository.
But it is also possible to serve multiple Fossil repositories from
a single CGI script.
If the CGI script for Fossil contains a "directory:" line instead of
a "repository:" line, then the argument to "directory:" is the name
of a directory that contains multiple repository files, each ending
with ".fossil". For example:
<pre>
#!/usr/bin/fossil
directory: /home/www/repos
</pre>
Suppose the /home/www/repos directory contains files named
<b>one.fossil</b>, <b>two.fossil</b>, and <b>subdir/three.fossil</b>.
Further suppose that the name of the CGI script (relative to the root
of the webserver document area) is "cgis/example2". Then to
see the timeline for the "three.fossil" repository, the URL would be:
<pre>
http://example.com/cgis/example2/subdir/three/timeline
</pre>
Here is what happens:
<ol>
<li> The input URI on the HTTP request is
<b>/cgis/example2/subdir/three/timeline</b>
<li> The web server searches prefixes of the input URI until it finds
the "cgis/example2" script. The web server then sets
PATH_INFO to the "subdir/three/timeline" suffix and invokes the
"cgis/example2" script.
<li> Fossil runs and sees the "directory:" line pointing to
"/home/www/repos". Fossil then starts pulling terms off the
front of the PATH_INFO looking for a repository. It first looks
at "/home/www/resps/subdir.fossil" but there is no such repository.
So then it looks at "/home/www/repos/subdir/three.fossil" and finds
a repository. The PATH_INFO is shortened by removing
"subdir/three/" leaving it at just "timeline".
<li> Fossil looks at the rest of PATH_INFO to see that the webpage
requested is "timeline".
</ol>
<a id="cgivar"></a>
The web server sets many environment variables in step 2 in addition
to just PATH_INFO. The following diagram shows a few of these variables
and their relationship to the request URL:

<h2>Additional CGI Script Options</h2>
The CGI script can have additional options used to fine-tune
Fossil's behavior. See the [./cgi.wiki|CGI script documentation]
for details.
<h2>Additional Observations</h2>
<ol type="I">
<li><p>
Fossil does not distinguish between the various HTTP methods (GET, PUT,
DELETE, etc). Fossil figures out what it needs to do purely from the
webpage term of the URI.</p></li>
<li><p>
Fossil does not distinguish between query parameters that are part of the
URI, application/x-www-form-urlencoded or multipart/form-data encoded
parameter that are part of the POST content, and cookies. Each information
source is seen as a space of key/value pairs which are loaded into an
internal property hash table. The code that runs to generate the reply
can then reference various properties values.
Fossil does not care where the value of each property comes from (POST
content, cookies, or query parameters) only that the property exists
and has a value.</p></li>
<li><p>
The "[/help?cmd=ui|fossil ui]" and "[/help?cmd=server|fossil server]" commands
are implemented using a simple built-in web server that accepts incoming HTTP
requests, translates each request into a CGI invocation, then creates a
separate child Fossil process to handle each request. In other words, CGI
is used internally to implement "fossil ui/server".
<br><br>
SCGI is processed using the same built-in web server, just modified
to parse SCGI requests instead of HTTP requests. Each SCGI request is
converted into CGI, then Fossil creates a separate child Fossil
process to handle each CGI request.</p></li>
<li><p>
Fossil is itself often launched using CGI. But Fossil can also then
turn around and launch [./serverext.wiki|sub-CGI scripts to implement
extensions].</p></li>

The "download.html" screen itself, and the various build products are all stored as unversioned content. The download.html page uses XMLHttpRequest() to retrieve the [/help?cmd=/juvlist|/juvlist] webpage for a list of all unversioned files. Javascript in the [/uv/download.js?mimetype=text/plain|download.js] file (which is sourced by "download.html") then figures out which unversioned files are build products and paints appropriate icons on the displayed download page. Except, the "Source Tarball" download products are not stored as unversioned files. They are computed on-demand by the [/help?cmd=/tarball|/tarball web page]. When a new version is generated, the developers use the [/help?cmd=uv|fossil uv edit] command to make minor changes to the "[/uv/download.js?mimetype=text/plain|download.js]" file so that it knows about the new version number. Then the developers run the [/help?cmd=uv|fossil uv add] command for each build product. Finally, the [/help?cmd=uv|fossil uv sync] command is run to push all the content up to servers. All [./selfhost.wiki|three self-hosting repositories] for Fossil are updated automatically. <h2>2.0 Details</h2> The current text of the "download.html" and "download.js" files can be seen at: * [/uv/download.html?mimetype=text/plain] * [/uv/download.js?mimetype=text/plain] Notice how the hyperlinks above use the "mimetype=text/plain" query parameter in order to display the file as plain text instead of the usual HTML or Javascript. The default mimetype for "download.html" is text/html. But because the entire page is enclosed within <verbatim><div class='fossil-doc' data-title='Download Page'>...</div></verbatim> Fossil knows to add its standard header and footer information to the document, making it look just like any other page. See "[./embeddeddoc.wiki|embedded documentation]" for further details on how this <div class='fossil-doc'> markup works. With each new release, the "releases" variable in the javascript on the [/uv/download.js?mimetype=text/plain|download.js] page is edited (using "[/help?cmd=uv|fossil uv edit download.js]") to add details of the release. When the JavaScript in the "download.js" file runs, it requests a listing of all unversioned content using the /juvlist URL. ([/juvlist|sample /juvlist output]). The content of the download page is constructed by matching unversioned files against regular expressions in the "releases" variable. Build products need to be constructed on different machines. The precompiled binary for Linux is compiled on Linux, the precompiled binary for Windows is compiled on Windows11, and so forth. After a new release is tagged, the release manager goes around to each of the target platforms, checks out the release and compiles it, then runs [/help?cmd=uv|fossil uv add] for the build product followed by [/help?cmd=uv|fossil uv sync] to push the new build product to the [./selfhost.wiki|various servers]. This process is repeated for each build product. When older builds are retired from the download page, the [/uv/download.js?mimetype=text/plain|download.js] page is again edited to remove the corresponding entry from the "release" variable and the edit is synced using [/help?cmd=uv|fossil uv sync]. This causes the build products to disappear from the download page immediately. But those build products are still taking up space in the unversioned content table of the server repository. To purge the obsolete build products, one or more [/help?cmd=uv|fossil uv rm] commands are run, followed by another [/help?cmd=uv|fossil uv sync]. It is important to purge obsolete build products since they take up a lot of space. At [/repo-tabsize] you can see that the unversioned table takes up a substantial fraction of the repository. <h2>3.0 Security</h2> Only users with the [/setup_ulist_notes|"y" permission] are allowed to push unversioned content up to the servers. Having the ability to push check-ins (the [/setup_ulist_notes|"i" permission]) is not sufficient. On the Fossil project there are (as of 2023-07-31) 71 people who have check-in privileges. But only the project lead can push unversioned content and thus change the build products on the download page. Minimizing the number of people who can change the build products helps to ensure that rogue binaries do not slip onto the download page unnoticed. |

<title>Adding Features To Fossil</title>
<h2>1.0 Introduction</h2>
This article provides a brief overview of how to write new C-code code that
extends or enhances the core Fossil binary.
New features can be added to a Fossil server using
[./serverext.wiki|external CGI programs],
but that is not what this article is about.
This article focuses on how to make changes
to Fossil itself.
<h2>2.0 Programming Language</h2>
Fossil is written in C-89. There are specific [./style.wiki | style guidelines]
that are required for any new code that will be accepted into the Fossil core.
But, of course, if you are writing an extension just for yourself, you can
use any programming style you want.
The source code for Fossil is not sent directly into the C compiler.
There are three separate code [./makefile.wiki#preprocessing|preprocessors]
that run over the code first.
1. The <b>mkindex</b> preprocessor scans all regular source files looking
for special comments that contain "help" text and which identify routines
that implement specific commands or which generate particular web pages.
2. The <b>makeheaders</b> preprocessor generates all the ".h" files
automatically. Fossil programmers write ".c" files only and let the
makeheaders preprocessor create the ".h" files.
3. The <b>translate</b> preprocessor converts source code lines that
begin with "@" into string literals, or into print statements that
generate web page output, depending on context.
The [./makefile.wiki|Makefile] for Fossil takes care of running these
preprocessors with all the right arguments and in the right order. So it is
not necessary to understand the details of how these preprocessors work.
(Though, the sources for all three preprocessors are included in the source
tree and are well commented, if you want to dig deeper.) It is only necessary
to know that these preprocessors exist and hence will affect the way you
write code.
<h2>3.0 Adding New Source Code Files</h2>
New source code files are added in the "src/" subdirectory of the Fossil
source tree. Suppose one wants to add a new source code file named
"xyzzy.c". The first step is to add this file to the various makefiles.
Do so by editing the file tools/makemake.tcl and adding "xyzzy" (without
the final ".c") to the list of source modules at the top of that script.
Save the result and then run the makemake.tcl script using a TCL
interpreter. The command to run the makemake.tcl script is:
<verbatim>
tclsh makemake.tcl
</verbatim>
The working directory must be src/ when the command above is run.
Note that TCL is not normally required to build Fossil, but
it is required for this step. If you do not have a TCL interpreter on
your system already, they are easy to install. A popular choice is the
[http://www.activestate.com/activetcl|Active Tcl] installation from
ActiveState.
After the makefiles have been updated, create the xyzzy.c source file
from the following template:
<verbatim>
/*
** Copyright boilerplate goes here.
*****************************************************
** High-level description of what this module goes
** here.
*/
#include "config.h"
#include "xyzzy.h"
#if INTERFACE
/* Exported object (structure) definitions or #defines
** go here */
#endif /* INTERFACE */
/* New code goes here */
</verbatim>
Note in particular the <b>#include "xyzzy.h"</b> line near the top.
The "xyzzy.h" file is automatically generated by makeheaders. Every
normal Fossil source file must have a #include at the top that imports
its private header file. (Some source files, such as "sqlite3.c" are
exceptions to this rule. Don't worry about those exceptions. The
files you write will require this #include line.)
The "#if INTERFACE ... #endif" section is optional and is only needed
if there are structure definitions or typedefs or macros that need to
be used by other source code files. The makeheaders preprocessor
uses definitions in the INTERFACE section to help it generate header
files. See [../tools/makeheaders.html | makeheaders.html] for additional
information.
After creating a template file such as shown above, and after updating
the makefiles, you should be able to recompile Fossil and have it include
your new source file, even before your source file contains any code.
It is recommended that you try this.
Be sure to [/help/add|fossil add] your new source file to the self-hosting
Fossil repository and then [/help/commit|commit] your changes!
<h2 id="newcmd">4.0 Creating A New Command</h2>
By "commands" we mean the keywords that follow "fossil" when invoking
Fossil from the command-line. So, for example, in
<verbatim>
fossil diff xyzzy.c
</verbatim>
The "command" is "diff". Commands may optionally be followed by
arguments and/or options. To create new commands in Fossil, add code
(either to an existing source file, or to a new source file created as
described above) according to the following template:
<verbatim>
/*
** COMMAND: xyzzy
**
** Help text goes here. Backslashes must be escaped.
*/
void xyzzy_cmd(void){
/* Implement the command here */
fossil_print("Hello, World!\n");
}
</verbatim>
The example above creates a new command named "xyzzy" that prints the
message "Hello, World!" on the console. This command is a normal command
that will show up in the list of command from [/help/help|fossil help].
If you add an asterisk to the end of the command name, like this:
<verbatim>
** COMMAND: xyzzy*
</verbatim>
Then the command will only show up if you add the "--all" option to
[/help/help|fossil help]. Or, if the command name starts with
"test" then the command will be considered experimental and will only
show up when the --test option is used with [/help/help|fossil help].
The example above is a fully functioning Fossil command. You can add
the text shown to an existing Fossil source file, recompiling then test
it out by typing:
<verbatim>
./fossil xyzzy
./fossil help xyzzy
./fossil xyzzy --help
</verbatim>
The name of the C function that implements the command can be anything
you like (as long as it does not collide with some other symbol in the
Fossil code) but it is traditional to name the function
"<i>commandname</i><b>_cmd</b>", as is done in the example.
You could also use "printf()" instead of "fossil_print()" to generate
the output text, if desired. But "fossil_print()" is recommended as
it has extra logic to insert \r characters at the right times on
Windows systems.
Once you have the command running, you can then start adding code to
make it do useful things. There are lots of utility functions in
Fossil for parsing command-line options and for
opening and accessing and manipulating the repository and
the working check-out. Study implementations of existing commands
to get an idea of how things are done. You can easily find the implementations
of existing commands by searching for "COMMAND: <i>name</i>" in the
files of the "src/" directory.
<h2 id="newpage">5.0 Creating A New Web Page</h2>
As with commands, new webpages can be added simply by inserting a function
that generates the webpage together with a special header comment. A
template follows:
<verbatim>
/*
** WEBPAGE: helloworld
*/
void helloworld_page(void){
style_header("Hello World!");
@ <p>Hello, World!</p>
style_footer();
}
</verbatim>
Add the code above to a new or existing Fossil source code file, then
recompile fossil and run [/help/ui|fossil ui] then enter
"http://localhost:8080/helloworld" in your web browser and the routine
above will generate a web page that says "Hello World."
It really is that simple.
The special "WEBPAGE:" comment is picked up by the "mkindex" preprocessor
and used to generate a table that maps the "helloworld" webpage name
into a pointer to the "helloworld_page()" function. The function that
implements a webpage can be named anything you like (as long as it does
not collide with another name) but the traditional name is
"<i>pagename</i><b>_page</b>".
HTML pages begin with a call to style_header() and end with the call to
style_footer(). Content is generated by the "@" lines that are translated
(by the "translate" preprocessor) into printf-like code that generates the
content of the webpage. Different techniques are used to generate
non-HTML content. In the unlikely event that you need to generate
non-HTML content, look at existing webpage implementations
(ex: "logo" or "style.css") to see how that is done.
There are lots of other things that a real web-page implementation will
need to do, such as verifying user credentials, parsing query parameters,
and interacting with the repository. But now that you have the general
idea of how webpages are implemented, you can look at the many other
webpage implementations already built into Fossil to see how all that
works.

# Email Alerts
## Overview
Beginning with version 2.7, Fossil can send email messages to
subscribers to alert them to changes in the repository:
* New [checkins](/help?cmd=ci)
* [Ticket](./tickets.wiki) changes
* [Wiki](./wikitheory.wiki) page changes
* New and edited [forum](./forum.wiki) posts
* Announcements
Subscribers can elect to receive emails as soon as these events happen,
or they can receive a daily digest of the events instead.
Email alerts are sent by a [Fossil server](./server/), which must be
[set up](#quick) by the Fossil administrator to send email.
Email alerts do not currently work if you are only using Fossil from the
command line.
A bit of terminology: Fossil uses the terms "email alerts" and
"notifications" interchangeably. We stick to the former term in this
document except when referring to parts of the Fossil UI still using the
latter term.
## Setup Prerequisites
Much of this document describes how to set up Fossil's email alert
system. To follow this guide, you will need a Fossil UI browser window
open to the [Admin → Notification](/setup_notification) Fossil UI screen
on the Fossil server that will be sending these email alerts, logged
in as a user with [**Admin** capability](./caps/ref.html#a). It is not possible to work on a
clone of the server's repository and push the configuration changes up
to that repo as an Admin user, [on purpose](#backup).
**Important:** Do not confuse that screen with Admin → Email-Server,
which sets up a different subsystem within Fossil. That feature is
related to this document's topic, but it is currently incomplete, so we
do not cover it at this time.
<a id="cd"></a>
You will also need a CLI window open with its working directory changed
to a checkout directory of the Fossil repository you are setting up to
send email. If you don't `cd` to such a checkout directory first,
you'll need to add `-R /path/to/repo.fossil` to each `fossil` command
below to tell Fossil which repository you mean it to apply the command
to.
There are other prerequisites for email service, but since they vary
depending on the configuration you choose, we'll cover these inline
below.
<a id="quick"></a>
## Quick Email Service Setup
If you've already got a working Postfix, Exim, or Sendmail server on the
machine running your Fossil instance(s), and you aren't using Fossil's
`chroot` feature to wall Fossil off from the rest of the machine, it's
fairly simple to set up email alerts.
(Otherwise, skip [ahead](#advanced) to the sections on advanced email
service setup.)
This is our "quick setup" option even though setting up an SMTP mail
server is not trivial, because there are many other reasons to have such
a server set up already: internal project email service, `cron`
notifications, server status monitoring notifications...
With that out of the way, the Fossil-specific steps are easy:
1. Go to [Admin → Notification](/setup_notification) and fill out all
of the **Required** fields:
* **Canonical server URL** — Use the suggested URL
* **"From" email address** — `forum-bounces@example.com` is
traditional, but suit yourself
* **Repository nickname** — See the suggested examples on the web page.
2. Set "Email Send Method" to "Pipe to a command"
3. Set the "Administrator email address" to a suitable valid email
address on that machine. It could be the same value you used for
the "From" address above, or it could be a different value like
`admin@example.com`.
Save your changes.
At the command line, say
$ fossil set email-send-command
If that gives a blank value instead of `sendmail -ti`, say
$ fossil set email-send-command "sendmail -ti"
to force the setting. That works around a [known
bug](https://fossil-scm.org/forum/forumpost/840b676410) which may be
squished by the time you read this.
If you're running Postfix or Exim, you might think that command is
wrong, since you aren't running Sendmail. These mail servers provide a
`sendmail` command for compatibility with software like Fossil that has
no good reason to care exactly which SMTP server implementation is
running at a given site. There may be other SMTP servers that also
provide a compatible `sendmail` command, in which case they may work
with Fossil using the same steps as above.
<a id="status"></a>
If you reload the Admin → Notification page, the Status section at the
top should show:
Outgoing Email: Piped to command "sendmail -ti"
Pending Alerts: 0 normal, 0 digest
Subscribers: 0 active, 0 total
Before you move on to the next section, you might like to read up on
[some subtleties](#pipe) with the "pipe to a command" method that we did
not cover above.
<a id="usage"></a>
## Usage and Testing
Now that email service from Fossil is set up, you can test it and begin
using it.
<a id="sub" name="subscribe"></a>
### Subscribing to Alerts
In the Status output above, we saw that there are no subscribers, so the
next step is to add the first one.
Go to the `/subscribe` page on your Fossil instance to sign up for email
alerts. At the very least, you will need to sign up for "Forum Posts"
and "Announcements" to complete the testing steps below.
If you're logged in with a Fossil repository user account and put the
same user name and email address into this forum as you used for your
user information under Admin → Users, Fossil will simply tie your alert
preferences to your login record, and the email address in your user's
Contact Info field will be considered already-verified. Otherwise,
Fossil will create an alert-only record, and you will have to verify the
email address before Fossil will send alerts to it.
This shows a key aspect of the way Fossil's email alerts system works,
by the way: a user can be signed up for email alerts without having a
full-fledged Fossil user account. Only when both user names are the same
are the two records tied together under the hood. For more on this, see
[Users vs Subscribers below](#uvs).
If you are seeing the following complaint from Fossil:
> Use a different login with greater privilege than FOO to access /subscribe
...then the repository's administrator forgot to give the
[**EmailAlert** capability][cap7]
to that user or to a user category that the user is a member of.
After a subscriber signs up for alerts for the first time, a single
verification email is sent to that subscriber's given email address.
The new subscriber must click a link in that email in order to activate
the subscription.
Subscription verification emails are only sent once. This is a defense
against malicious robots that try to harass innocent Internet users by
having subscription pages send multiple verification emails. If the
initial subscription verification does not go through correctly, an
administrator must [intervene](#admin) to reset the subscription.
Every subscriber-only email address has a [long random hexadecimal
security code](#scode) that serves in place of a password. All email
alerts contain a link in their footer back to the Fossil server,
incorporating this security code, which allows the subscriber to adjust
their subscription options. If a user doesn't have any of those emails,
they can request a link via email by visiting the `/alerts` or
`/unsubscribe` page on the repository.
Those with Fossil repository logins can adjust their email alert
settings by visiting the `/alerts` page on the repository. With the
default skin, you can get there by clicking the "Logout" link in the
upper right corner of any Fossil UI page then clicking the "Email
Alerts" link. That link is also available via the Sitemap (`/sitemap`)
and via the default skin's hamburger menu (☰).
[cap7]: ./caps/ref.html#7
<a id="unsub" name="unsubscribe"></a>
### Unsubscribing
To unsubscribe from alerts, visit the `/alerts` page on the repository,
click the "Unsubscribe" button, then check the "Unsubscribe" checkbox to
verify your action and press the "Unsubscribe" button a second time.
This interlock is intended to prevent accidental unsubscription.
<a id="test"></a>
### Test Email Service
The easiest way to test email sending from Fossil is via the "[Send
Announcement](/announce)" link at the top of the "Email Notification
Setup" page. Put your email address in the "To:" line and a test
message below, then press "Send Message" to verify that outgoing email
is working.
Another method is from the command line:
$ fossil alerts test-message you@example.com --body README.md --subject Test
That should send you an email with "Test" in the subject line and the
contents of your project's `README.md` file in the body.
That command assumes that your project contains a "readme" file, but of
course it does, because you have followed the [Programming Style Guide
Checklist][cl], right? Right.

<a id="cap7" name="ucap"></a>
### User Capabilities
Once email alerts are working, you may need to [adjust the default user
capabilities](./caps/) to give "[Email Alerts][cap7]" capability to any
[user category](./caps/#ucat) or [individual user](./caps/#ucap) that
needs to use the subscription setup pages, `/subscribe` and `/alerts`.
[**Admin**][capa] and [**Setup**][caps] users always have this
capability.
To allow any passer-by on the Internet to subscribe, give the "Email
Alerts" capability to the "nobody" user category. To require that a
person solve a simple CAPTCHA first, give that capability to the
"anonymous" user category instead.

[caps]: ./caps/ref.html#s
<a id="first" name="frist"></a>
### First Post
I suggest taking the time to compose a suitable introductory message
especially for your project's forum, one which a new user would find
helpful.
Wait a few seconds, and you should receive an email alert with the
post's subject and body text in the email.
<a id="trouble"></a>
### Troubleshooting
If email alerts aren't working, there are several useful commands you
can give to figure out why.
(Be sure to [`cd` into a repo checkout directory](#cd) first!)
$ fossil alerts status
This should give much the same information as you saw [above](#status).
One difference is that, since you've created a forum post, the
`pending-alerts` value should only be zero if you did in fact get the
requested email alert. If it's zero, check your mailer's spam folder. If
it's nonzero, continue with these troubleshooting steps.
$ fossil backoffice
That forces Fossil to run its ["back office" process](./backoffice.md).
Its only purpose at the time of this writing is to push out alert
emails, but it might do other things later. Sometimes it can get stuck
and needs to be kicked. For that reason, you might want to set up a
crontab entry to make sure it runs occasionally.
$ fossil alerts send
This should also kick off the backoffice processing, if there are any
pending alerts to send out.
$ fossil alert pending
Show any pending alerts. The number of lines output here should equal
the [status output above](#status).
$ fossil test-add-alerts f5900
$ fossil alert send
Manually create an email alert and push it out immediately.
The `f` in the first command's final parameter means you're scheduling a
"forum" alert. The integer is the ID of a forum post, which you can find
by visiting `/timeline?showid` on your Fossil instance.
The second command above is necessary because the `test-add-alerts`
command doesn't kick off a backoffice run.
$ fossil ale send
This only does the same thing as the final command above, rather than
send you an ale, as you might be hoping. Sorry.
<a id="advanced"></a>
## Advanced Email Setups
Fossil offers several methods of sending email:
1. Pipe the email message text into a command.
2. Store email messages as entries in an SQLite database.
3. Store email messages as individual files in a directory.
4. Send emails to an SMTP relay.
5. Send emails directly to the recipients via SMTP.
This wide range of options allows Fossil to talk to pretty much any
SMTP setup.
The first four options let Fossil delegate email handling to an existing
[MTA] so that Fossil does not need to implement the [roughly two
dozen][mprotos] separate [RFCs][rfcs] required in order to properly
support SMTP email in this complex world we've built. As well, this
design choice means you do not need to do duplicate configuration, such
as to point Fossil at your server's TLS certificate in order to support
users behind mail servers that require STARTTLS encryption.

[rfcs]: https://en.wikipedia.org/wiki/Request_for_Comments
<a id="pipe"></a>
### Method 1: Pipe to a Command
This is our ["quick setup" option](#quick) above, but there are some
details we ignored which we'll cover now.
Fossil pipes the email message in [RFC 822 format][rfc822] to the
standard input of the command you gave as the "Email Send Method",
defaulting to `sendmail -ti`. This constitutes a protocol between Fossil
and the SMTP [message transfer agent (MTA)][MTA]. Any other MTA which
speaks the same protocol can be used in place of the most common
options: Sendmail, Exim, and Postfix.
The `-t` option tells the command to expect the list of email recipients
in a `To` header in the RFC 822 message presented on its standard input.
Without this option, the `sendmail` command expects to receive the
recipient list on the command line, but that's not possible with the
current design of this email sending method. Therefore, if you're
attempting to use a less common MTA which cannot parse the recipient
list from the `To` header in the email message, you might need to look
for a different MTA.
The `-i` option is only needed for MTAs that take a dot/period at the
beginning of a line of standard input text as "end of message." Fossil
doesn't attempt to escape such dots, so if the line wrapping happens to
occur such that a dot or period in an alert message is at the beginning
of a line, you'll get a truncated email message without this option.
Statistically, this will happen about once every 70 or so messages, so
it is important to give this option if your MTA treats leading dots on a
line this way.
<a id="msmtp"></a>
The [`msmtp`][msmtp] SMTP client is compatible with this
protocol if you give it the `-t` option. It’s a useful option on a server
hosting a Fossil repository which doesn't otherwise require a separate
SMTP server for other purposes, such as because you’ve got a separate
provider for your email and merely need a way to let Fossil feed
messages into it.
It is probably also possible to configure [`procmail`][pmdoc] to work
with this protocol. If you know how to do it, a patch to this document
or a how-to on [the Fossil forum][ff] would be appreciated.

<a id="db"></a>
### Method 2: Store in a Database
The self-hosting Fossil repository at <https://fossil-scm.org/>
currently uses this method rather than [the pipe method](#pipe) because
it is running inside of a restrictive [chroot jail][cj] which is unable
to hand off messages to the local MTA directly.
When you configure a Fossil server this way, it adds outgoing email
messages to an SQLite database file. A separate daemon process can then
extract those messages for further disposition.
Fossil includes a copy of [the daemon](/file/tools/email-sender.tcl)
used on `fossil-scm.org`: it is just a short Tcl script that
continuously monitors this database for new messages and hands any that
it finds off to a local MTA using the same [pipe to MTA protocol](#pipe)
as above.
In this way, outbound email alerts escape the chroot jail without
requiring that we insert a separate MTA configuration inside that jail.
We only need to arrange that the same SQLite DB file be visible both
inside and outside the chroot jail, which we do by naming the database
file in the "Store Emails In This Database" setting under Admin →
Notification. The Tcl script has this path hard-coded as
`/home/www/fossil/emailqueue.db`, but you will probably need to adjust
that for your local purposes.
This method may work with other similar technologies besides `chroot`:
Docker containers, LXC containers, BSD jails, Solaris zones, etc.
With suitable file share mappings, this method may even work with
virtual machine or distributed computing setups where the MTA and Fossil
servers are not on the same machine, though beware the [risk of DB
corruption][rdbc] if used with a file sharing technology that doesn't
use proper file locking.
You can start this Tcl script as a daemon automatically on most Unix and
Unix-like systems by adding the following line to the `/etc/rc.local`
file of the server that hosts the repository sending email alerts:
/usr/bin/tclsh /home/www/fossil/email-sender.tcl &
[cj]: https://en.wikipedia.org/wiki/Chroot
[rdbc]: https://www.sqlite.org/howtocorrupt.html#_filesystems_with_broken_or_missing_lock_implementations
<a id="dir"></a>
### Method 3: Store in a Directory
This method is functionally very similar to [the DB method](#db),
differing only in that messages are written to a directory in the
filesystem. You should therefore read that section and make the minor
adjustments required by the storage method.
This method may work over a file sharing mechanism that doesn't do file
locking properly, as long as the reading process is somehow restricted
from reading a message file as it's being written.
It might be useful in testing and debugging to temporarily switch to
this method, since you can easily read the generated email messages
without needing to involve an [MTA].
<a id="relay"></a>
### Method 4: SMTP Relay
In this configuration, the Fossil server contacts an open SMTP relay and
sends the messages to it. This method is only appropriate when:
1. You have a local MTA that doesn't accept [the pipe
protocol](#pipe).
2. The MTA is willing to accept anonymous submissions, since Fossil
currently has no way to authenticate itself to the MTA. This is [an
unsafe configuration][omr] in most cases, but some SMTP servers make
an exception for connections coming from a `localhost` or LAN
address, choosing to accept such submissions as inherently safe.
If you have a local MTA meeting criterion #1 but not #2, we'd suggest
using a more powerful SMTP client such as [msmtp](#msmtp) along with one
of the other methods above.

### Method 5: Direct SMTP Send
As of Fossil 2.7, the code to support this method is incomplete, so you
cannot currently select it as an option in Admin → Notification.
<a id="uvs"></a>
## Users vs Subscribers
Fossil makes a distinction between "users" and "subscribers". A user is
someone with a username and password: that is, someone who can log into
the Fossil repository. A subscriber is someone who receives email
alerts. Users can also be subscribers and subscribers can be users, but
that does not have to be the case. It is possible to be a user without
being a subscriber and to be a subscriber without being a user.
In the repository database file, users are tracked with the `user` table
and subscribers are tracked via the `subscriber` table.
<a id="admin"></a>
## Administrator Activities
The "[List Subscribers](/subscribers)" button at the top of the Admin →
Notification screen gives a list of subscribers, which gives a Fossil
server administrator a lot of power over those subscriptions.
Clicking an email address in this subscriber list opens the same
`/alerts` page that the user can see for their own subscription, but
with more information and functionality than normal users get:
* Subscription creation and modification timestamps.
* The IP address the user had when they last made a change via either
`/subscribe` or `/alert`.
* The user's login name, if they are not [a mere subscriber](#uvs). A
Fossil Admin user is allowed to modify this, either to tie a
subscription-only record to an existing Fossil user account or to
break that tie.
* The "Do not call" checkbox allows a Fossil Admin user to mark a given
email address so that Fossil never sends email to that address. This
is distinct from unsubscribing that email address because it prevents
Fossil from accepting a new subscription for that address.
* The Verified checkbox is initially unchecked for subscriber-only
email addresses until the user clicks the link in the verification
email. This checkbox lets the Fossil Admin user manually verify the
user, such as in the case where the verification email message got
lost. Unchecking this box does not cause another verification email
to be sent.
This screen also allows a Fossil Admin user to perform other activities
on behalf of a subscriber which they could do themselves, such as to
[unsubscribe](#unsub) them.

Administrator-only web pages:
* The [`/setup_notification`](/help?cmd=/setup_notification) page
* The [`/subscribers`](/help?cmd=/subscribers) page
<a id="design"></a>
## Design of Email Alerts
This section describes the low-level design of the email alert system in
Fossil. This expands on the high-level administration focused material
above with minimal repetition.
This section assumes expert-level systems knowledge. If the material
above sufficed for your purposes, feel free to skip this section, which
runs to the end of this document.
<a id="datades"></a>
### Data Design
There are two new tables in the repository database, starting with
Fossil 2.7. These tables are not created in new repositories by
default. The tables only come into existence as needed when email
alerts are configured and used.
* <b>SUBSCRIBER</b> →
The subscriber table records the email address for people who
want to receive email notifications. Each subscriber has a
`subscriberCode` which is a random 32-byte blob that uniquely
identifies the subscriber. There are also fields to indicate
what kinds of notifications the subscriber wishes to receive,
whether or not the email address of the subscriber has been
verified, etc.
* <b>PENDING\_ALERT</b> →
The PENDING\_ALERT table contains records that define events
about which alert emails might need to be sent.
A pending\_alert always refers to an entry in the
EVENT table. The EVENT table is part of the standard schema
and records timeline entries. In other words, there is one
row in the EVENT table for each possible timeline entry. The
PENDING\_ALERT table refers to EVENT table entries for which
we might need to send alert emails.
As pointed out above, ["subscribers" are distinct from "users"](#uvs).
The SUBSCRIBER.SUNAME field is the optional linkage between users and
subscribers.
<a id="stdout"></a>
### The "stdout" Method
The [list of mail sending methods](#advanced) above left out an
internal-only method called "stdout" which simply writes the text of the
email message on standard output. The "stdout" method is used for
testing and debugging. If you need something similar and can't modify
your local Fossil instance to use this method, you might temporarily
switch to [the "dir" method](#dir) instead.
<a id="msgfmt"></a>
### Message Format
The email messages generated by Fossil have a [well-formed
header][rfc822]. The downstream processing is expected to extract the
"To:", "From:", "Subject:" and whatever other attributes it needs from
the email header text.
These emails use the `text/plain` MIME type with the UTF-8 character
set. We currently use a transfer encoding of `quoted-printable`, but
there is commented-out code in Fossil to switch to `base64` encoding,
which Fossil used in the early days leading up to the 2.7 release.
If you switch Fossil back to `base64` mode, you may want to build a
utility program that ships in the Fossil source tree named
["tools/decode-email.c"](/file/tools/decode-email.c) which can decode
these messages into a human-readable format.
<a id="inbound" name="bounces"></a>
### Dealing with Inbound Email
Inbound email messages — for example, bounces from failed alert emails —
should be relayed to the `fossil email inbound` command. That command
is currently a no-op place-holder. At some point, we will need to
design and write a bounce-message processing system for Fossil.
<a id="password" name="scode" name="verification"></a>
### Passwords vs Subscriber Codes
When anonymous passers-by on the Internet sign up for email alerts,
their email address must first be verified. An email message is sent to
the address supplied inviting the user to click on a link. The link
includes a pseudorandom 128-bit blob encoded as 32 hexadecimal digits,
which serves in place of a password for that email address. (This is
stored in the database as `subscriber.subscriberCode`.) If anyone visits
the link, the email address is verified.
Knowledge of the `subscriberCode` is sufficient to control a
subscription.
Because this code is included in plain text in email alert messages, it
is not as secure as a separate password, but it has several virtues:
* It is easier for the average subscriber to deal with in that they
don't have to come up with yet another password and store it safely.
* If the `subscriberCode` is stolen, the worst that can happen is that
the thief can change that email address's subscription settings.
Contrast a password which may be shared with other services, which
then compromises those other services.
* No PII other than the subscriber's email address is available to an
attacker with the `subscriberCode`. Nor can knowledge of the
`subscriberCode` lead to an email flood or other annoyance attack, as
far as I can see.
If the `subscriberCodes` for a Fossil repository are ever compromised,
new ones can be generated as follows:
UPDATE subscriber SET subscriberCode=randomblob(32);
Since this then affects all new email alerts going out from Fossil, your
end users may never even realize that they're getting new codes, as long
as they don't click on the URLs in the footer of old alert messages.
With that in mind, a Fossil server administrator could choose to
randomize the `subscriberCodes` periodically, such as just before the
daily digest emails are sent out each day.
**Important:** All of the above is distinct from the passwords for users
with a Fossil repository login. Such users also have subscriber codes,
but those codes can only be used to modify the user's email alert
settings. That code cannot allow a user to log into the user's Fossil
repository account.
<a id="processing"></a>
### Internal Processing Flow
Almost all of the email alert code is found in the
[`src/alerts.c`](/file/src/alerts.c) source file.
When email alerts are enabled, a trigger is created in the schema
(`email_trigger1`) that adds a new entry to the `PENDING_ALERT` table
every time a row is added to the `EVENT` table. During a
`fossil rebuild`, the `EVENT` table is rebuilt from scratch; since we do not
want users to get alerts for every historical check-in, the trigger is
disabled during `rebuild`.
Email alerts are sent out by the `alert_send_alerts()` function, which
is normally called automatically due to the `email-autoexec` setting,
which defaults to enabled. If that setting is disabled or if the user
simply wants to force email alerts to be sent immediately, they can give
a `fossil alert send` command, such as via a `cron` script. Each time
this function is called, the alert messages are moved further down the
chain, so you cannot cause duplicate alerts by calling it too often.
Digests are handled by recording the time of the last digest in the
`email-last-digest` setting, and only sending a new digest if the
current time is one day or later after the last digest.
Individual emails are sent to each subscriber. I (drh) ran tests and
found that I could send about 1200 emails/second, which is fast enough
that I do not need to resort to trying to notify multiple subscribers
with a single email. Because each subscriber gets a separate email, the
system can include information in the email that is unique to the
subscriber, such as a link to the page to edit their subscription. That
link includes the `subscriberCode`.

<title>Defense Against Robots</title>
A typical Fossil website can have millions of pages, and many of
those pages (for example diffs and annotations and tarballs) can
be expensive to compute.
If a robot walks a Fossil-generated website,
it can present a crippling bandwidth and CPU load.
A Fossil website is intended to be used
interactively by humans, not walked by robots. This article
describes the techniques used by Fossil to try to welcome human
users while keeping out robots.
<h2>The Hyperlink User Capability</h2>
Every Fossil web session has a "user". For random passers-by on the internet
(and for robots) that user is "nobody". The "anonymous" user is also
available for humans who do not wish to identify themselves. The difference
is that "anonymous" requires a login (using a password supplied via
a CAPTCHA) whereas "nobody" does not require a login.
The site administrator can also create logins with
passwords for specific individuals.
Users without the <b>[./caps/ref.html#h | Hyperlink]</b> capability
do not see most Fossil-generated hyperlinks. This is
a simple defense against robots, since [./caps/#ucat | the "nobody"
user category] does not have this capability by default.
Users must log in (perhaps as
"anonymous") before they can see any of the hyperlinks. A robot
that cannot log into your Fossil repository will be unable to walk
its historical check-ins, create diffs between versions, pull zip
archives, etc. by visiting links, because there are no links.
A text message appears at the top of each page in this situation to
invite humans to log in as anonymous in order to activate hyperlinks.
But requiring a login, even an anonymous login, can be annoying.
Fossil provides other techniques for blocking robots which
are less cumbersome to humans.
<h2>Automatic Hyperlinks Based on UserAgent</h2>
Fossil has the ability to selectively enable hyperlinks for users
that lack the <b>Hyperlink</b> capability based on their UserAgent string in the
HTTP request header and on the browsers ability to run Javascript.
The UserAgent string is a text identifier that is included in the header
of most HTTP requests that identifies the specific maker and version of
the browser (or robot) that generated the request. Typical UserAgent
strings look like this:
<ul>
<li> Mozilla/5.0 (Windows NT 6.1; rv:19.0) Gecko/20100101 Firefox/19.0
<li> Mozilla/4.0 (compatible; MSIE 8.0; Windows_NT 5.1; Trident/4.0)
<li> Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
<li> Wget/1.12 (openbsd4.9)
</ul>
The first two UserAgent strings above identify Firefox 19 and
Internet Explorer 8.0, both running on Windows NT. The third
example is the robot used by Google to index the internet.
The fourth example is the "wget" utility running on OpenBSD.
Thus the first two UserAgent strings above identify the requester
as human whereas the second two identify the requester as a robot.
Note that the UserAgent string is completely under the control
of the requester and so a malicious robot can forge a UserAgent
string that makes it look like a human. But most robots want
to "play nicely" on the internet and are quite open
about the fact that they are a robot. And so the UserAgent string
provides a good first-guess about whether or not a request originates
from a human or a robot.
In Fossil, under the Admin/Robot-Defense menu, there is a setting entitled
"<b>Enable hyperlinks based on User-Agent and/or Javascript</b>".
If this setting is set to "UserAgent only" or "UserAgent and Javascript",
and if the UserAgent string looks like a human and not a robot, then
Fossil will enable hyperlinks even if the <b>Hyperlink</b> capability
is omitted from the user permissions. This setting gives humans easy
access to the hyperlinks while preventing robots
from walking the billions of pages on a typical Fossil site.
If the setting is "UserAgent only", then the hyperlinks are simply
enabled and that is all. But if the setting is "UserAgent and Javascript",
then the hyperlinks are not enabled directly.
Instead, the HTML code that is generated contains anchor tags ("<a>")
with "href=" attributes that point to [/honeypot] rather than the correct
link. JavaScript code is added to the end of the page that goes back and
fills in the correct "href=" attributes of
the anchor tags with the true hyperlink targets, thus enabling the hyperlinks.
This extra step of using JavaScript to enable the hyperlink targets
is a security measure against robots that forge a human-looking
UserAgent string. Most robots do not bother to run JavaScript and
so to the robot the empty anchor tag will be useless. But all modern
web browsers implement JavaScript, so hyperlinks will show up
normally for human users.
<h2>Further Defenses</h2>
Recently (as of this writing, in the spring of 2013) the Fossil server
on the SQLite website ([http://www.sqlite.org/src/]) has been hit repeatedly
by Chinese robots that use forged UserAgent strings to make them look
like normal web browsers and which interpret JavaScript. We do not
believe these attacks to be nefarious since SQLite is public domain
and the attackers could obtain all information they ever wanted to
know about SQLite simply by cloning the repository. Instead, we
believe these "attacks" are coming from "script kiddies". But regardless
of whether or not malice is involved, these attacks do present
an unnecessary load on the server which reduces the responsiveness of
the SQLite website for well-behaved and socially responsible users.
For this reason, additional defenses against
robots have been put in place.
On the Admin/Robot-Defense page of Fossil, just below the
"<b>Enable hyperlinks using User-Agent and/or Javascript</b>"
setting, there are now two additional sub-settings that can be optionally
enabled to control hyperlinks.
The first new sub-setting is a delay (in milliseconds) before setting
the "href=" attributes on anchor tags. The default value for this
delay is 10 milliseconds. The idea here is that a robots will try to
interpret the links on the page immediately, and will not wait for delayed
scripts to be run, and thus will never enable the true links.
The second sub-setting waits to run the
JavaScript that sets the "href=" attributes on anchor tags until after
at least one "mousedown" or "mousemove" event has been detected on the
<body> element of the page. The thinking here is that robots will not be
simulating mouse motion and so no mouse events will ever occur and
hence the hyperlinks will never become enabled for robots.
See also [./loadmgmt.md|Managing Server Load] for a description
of how expensive pages can be disabled when the server is under heavy
load.
<h2>The Ongoing Struggle</h2>
Fossil currently does a very good job of providing easy access to humans
while keeping out troublesome robots. However, robots
continue to grow more sophisticated, requiring ever more advanced
defenses. This "arms race" is unlikely to ever end. The developers of
Fossil will continue to try improve the robot defenses of Fossil so
check back from time to time for the latest releases and updates.
Readers of this page who have suggestions on how to improve the robot
defenses in Fossil are invited to submit your ideas to the Fossil Users
forum:

Backoffice
==========
This is technical documentation about the internal workings of Fossil.
Ordinary Fossil users do not need to know about anything covered by this
document. The information here is intended for people who want to enhance
or extend the Fossil code, or who just want a deeper understanding of
the internal workings of Fossil.
What Is The Backoffice
----------------------
The backoffice is a mechanism used by a
[Fossil server](./server/) to do low-priority
background work that is not directly related to the user interface. Here
are some examples of the kinds of work that backoffice performs:
1. Sending email alerts and notifications
2. Sending out daily digests of email notifications
3. Other background email handling chores
4. Automatic syncing of peer repositories
5. Repository maintenance and optimization
(As of 2018-08-07, only items 1 and 2 have actually been implemented.)
The idea is that the backoffice handles behind-the-scenes work that does
not have tight latency requirements.
When Backoffice Runs
--------------------
A backoffice process is usually launched automatically by a webpage
request. After each webpage is generated, Fossil checks to see if any
backoffice work needs to be done. If there is work to do, and no other
process is already assigned to do the work, then a new backoffice process
is started to do the work.
This happens for every webpage, regardless of how that webpage is launched,
and regardless of the purpose of the webpage. This also happens on the
server for "[fossil sync](/help?cmd=sync)" and
[fossil clone](/help?cmd=clone)" commands which are implemented as
web requests - albeit requests that the human user never sees.
Web requests can arrive at the Fossil server via direct TCP/IP (for example
when Fossil is started using commands like "[fossil server](/help?cmd=server)")
or via [CGI](./server/any/cgi.md) or
[SCGI](./server/any/scgi.md) or via SSH.
A backoffice process might be started regardless of the origin of the
request.
The backoffice is not a daemon. Each backoffice process runs for a short
while and then exits. This helps keep Fossil easy to manage, since there
are no daemons to start and stop. To upgrade Fossil to a new version,
you simply replace the older "fossil" executable with the newer one, and
the backoffice processes will (within a minute or so) start using the new
one. (Upgrading the executable on Windows is more complicated, since on
Windows it is not possible to replace an executable file that is in active
use. But Windows users probably already know this.)
The backoffice is serialized and rate limited. No more than a single
backoffice process will be running at once, and backoffice runs will not
occur more frequently than once every 60 seconds. (The 60-second spacing
is controlled by the BKOFCE_LEASE_TIME macro in the
[backoffice.c](/file/src/backoffice.c) source file.)
If a Fossil server is idle, then no backoffice processes will be running.
That means there are no extra processes sitting around taking up memory
and process table slots for seldom accessed repositories.
The backoffice is an on-demand system.
A busy repository will usually have a backoffice
running at all times. But an infrequently accessed repository will only have
backoffice processes running for a minute or two following the most recent
access.
Manually Running The Backoffice
-------------------------------
The automatic backoffice runs are sufficient for most installations.
However, the daily digest of email notifications is handled by the
backoffice. If a Fossil server can sometimes go more than a day without
being accessed, then the automatic backoffice will never run, and the
daily digest might not go out until somebody does visit a webpage.
If this is a problem, an administrator can set up a cron job to
periodically run:
fossil backoffice _REPOSITORY_
That command will cause backoffice processing to occur immediately.
Note that this is almost never necessary for an internet-facing
Fossil repository, since most repositories will get multiple accesses
per day from random robots, which will be sufficient to kick off the
daily digest emails. And even for a private server, if there is very
little traffic, then the daily digests are probably a no-op anyhow
and won't be missed.
Automatic Backoffice Does Not Work On Some Systems
--------------------------------------------------
We have observed that the automatic backoffice does not work on
some system - OpenBSD in particular. We still do not understand why
this is. (If you have insights, please share them on the
[Fossil Forum](https://fossil-scm.org/forum) so that we can perhaps
fix the problem.) For now, the backoffice must be run manually
on OpenBSD systems.
To set up fully-manual backoffice, first disable the automatic backoffice
using the "[backoffice-disable](/help?cmd=backoffice-disable)" setting.
fossil setting backoffice-disable on
Then arrange to invoke the backoffice separately using a command
like this:
fossil backoffice --poll 30 _REPOSITORY-LIST_
Multiple repositories can be named. This one command will handle
launching the backoffice for all of them. There are additional useful
command-line options. See the "[fossil backoffice](/help?cmd=backoffice)"
documentation for details.
The backoffice processes run manually using the "fossil backoffice"
command do not normally use a lease. That means that if you run the
"fossil backoffice" command with --poll and you forget to disable
automatic backoffice by setting the "backoffice-disable" flag, then
you might have one backoffice running due to a command and another due
to a webpage access, both at the same time. This is harmless. The
only downside is that it uses extra CPU time.
How Backoffice Is Implemented
-----------------------------
The backoffice is implemented by the
"[backoffice.c](/file/src/backoffice.c)" source file.
Serialization and rate limiting is handled by a single entry in the
repository database CONFIG table named "backoffice". This entry is
called "the lease". The value of the lease
is a text string representing four integers, which
are respectively:
1. The process id of the "current" backoffice process
2. The lease expiration time of the current backoffice process
3. The process id of the "next" backoffice process
4. The lease expiration time for the next backoffice process
Times are expressed in seconds since 1970. A process id of zero means
"no process". Sometimes the process id will be non-zero even if there
is no corresponding process. Fossil knows how to figure out whether or
not a process still exists.
You can print out a decoded copy of the current backoffice lease using
this command:
fossil test-backoffice-lease -R _REPOSITORY_
If a system has been idle for a long time, then there will be no
backoffice processes. (Either the process id entries in the lease
will be zero, or there will exist no process associated with the
process id.) When a new web request comes in, the system
sees that no backoffice process is active and so it kicks off a separate
process to run backoffice.
The new backoffice process becomes the "current" process. It sets a
lease expiration time for itself to be 60 seconds in the future.
Then it does the backoffice processing and exits. Note that usually
the backoffice process will exit long before its lease expires. That
is ok. The lease is there to limit the rate at which backoffice processes
run.
If a new backoffice process starts up and sees that the "current" lease has
yet to expire, the new process makes itself the "next" backoffice process
and sets its expiration time to be 60 seconds past the expiration time of
the "current" backoffice process. The "next" process then puts itself to
sleep until the "current" lease expires. After the "current"
lease expires and the "current" process has itself exited, then
the "next" process promotes itself to the new "current" process. It
sets the current lease expiration to be 60 seconds in the future, runs
whatever backoffice work is needed, then exits.
If a new backoffice process starts up and finds that there is already
a "current" lease and a "next" process, it exits without doing anything.
This should happen only rarely, since the lease information is checked
prior to spawning the backoffice process, so a conflict will only happen
in a race.
Because the "backoffice" entry of the CONFIG table is in the repository
database, access to the lease is serialized. The lease prevents more
than one backoffice process from running at a time. It prevents
backoffice processes from running more frequently than once every 60 seconds.
And, it guarantees (assuming processes are not killed out-of-band) that
every web request will be followed within 60 seconds by a backoffice
run.
Debugging The Backoffice
------------------------
The backoffice should "just work". It should not require administrator
attention. However, if you suspect that something is not working right,
there are some debugging aids.
We have already mentioned the command that shows the backoffice lease
for a repository:
fossil test-backoffice-lease -R _REPOSITORY_
Running that command every few seconds should show what is going on with
backoffice processing in a particular repository.
There are also settings that control backoffice behavior. The
"backoffice-nodelay" setting prevents the "next" process from taking a
lease and sleeping. If "backoffice-nodelay" is set, that causes all
backoffice processes to exit either immediately or after doing whatever
backoffice works needs to be done. If something is going wrong and
backoffice leases are causing delays in webpage processing, then setting
"backoffice-nodelay" to true can work around the problem until the bug
can be fixed. The "backoffice-logfile" setting is the name of a log
file onto which is appended a short message every time a backoffice
process actually starts to do the backoffice work. This log file can
be used to verify that backoffice really is running, if there is any
doubt. The "backoffice-disable" setting prevents automatic backoffice
processing, if true. Use this to completely disable backoffice processing
that occurs automatically after each HTTP request. The "backoffice-disable"
setting does not affect the operation of the manual
"fossil backoffice" command.
Most installations should leave "backoffice-nodelay" and "backoffice-disable"
set to their default values of off and
leave "backoffice-logfile" unset or set to an empty string.

# Backing Up a Remote Fossil Repository
One of the great benefits of Fossil and other [distributed version control systems][dvcs]
is that cloning a repository makes a backup. If you are running a project with multiple
developers who share their work using a [central server][server] and the server hardware
catches fire, the clones of the repository on each developer
workstation *may* serve as a suitable backup.
[dvcs]: wikipedia:/wiki/Distributed_version_control
[server]: ./server/whyuseaserver.wiki
We say “may†because
it turns out not everything in a Fossil repository is copied when cloning. You
don’t even always get copies of all historical file artifacts. More than
that, a Fossil repository typically contains
other useful information that is not always shared as part of a clone, which might need
to be backed up separately. To wit:
## <a id="pii"></a> Sensitive Information
Fossil purposefully does not clone certain sensitive information unless
you’re logged in as a user with [Setup] capability. As an example, a local clone
may have a different `user` table than the remote, because only a
Setup user is allowed to see the full version for privacy and security
reasons.
## <a id="config"></a> Configuration Drift
Fossil allows the local configuration to differ in several areas from
that of the remote. You get a copy
of *some* of these configuration areas on initial clone — not all! — but after that,
remote configuration changes mostly do not sync down automatically.
#### <a id="skin"></a> Skin
Changes to the remote’s skin don’t sync down, on purpose, since you may
want to have a different skin on the local clone than on the remote. You
can ask for updates with [`fossil config pull skin`][cfg], but that does
not happen automatically during the course of normal development.
#### <a id="alerts"></a> Email Alerts
The Admin → Notification settings do not get copied on clone or sync,
and it is not possible to push such settings from one repository to
another. We did this on purpose because you may have a network of peer
repositories, and you only want one repository sending email alerts. If
Fossil were to automatically replicate the email alert settings to a
separate repository, subscribers would get multiple alerts for each
event, which would be *bad.*
The only element of the email alert configuration that can be pulled
over the sync protocol on demand is the subscriber list, via
[`fossil config pull subscriber`][cfg].
#### <a id="project"></a> Project Configuration
This is normally generated once during `fossil init` and never changed,
so Fossil doesn’t pull this information without being forced, on
purpose. You could accidentally merge two separate Fossil repos by
pushing one repo’s project config up to another, for example.
#### <a id="other-cfg"></a> Others
A repo’s URL aliases, [interwiki configuration](./interwiki.md), and
[ticket customizations](./custom_tcket.wiki) also do not normally sync.
[cfg]: /help?cmd=configuration
## <a id="private"></a> Private Branches
The very nature of Fossil’s [private branch feature][pbr] ensures that
remote clones don’t get a copy of those branches. Normally this is
exactly what you want, but in the case of making backups, you probably
want to back up these branches as well. One of the two backup methods below
provides this.
## <a id="shun"></a> Shunned Artifacts
Fossil purposefully doesn’t sync [shunned artifacts][shun]. If you want
your local clone to be a precise match to the remote, it needs to track
changes to the shun table as well.
## <a id="uv"></a> Unversioned Artifacts
Data in Fossil’s [unversioned artifacts table][uv] doesn’t sync down by
default unless you specifically ask for it. Like local configuration
data, it doesn’t get pulled as part of a normal `fossil sync`, but
*unlike* the config data, you don’t get unversioned files as part of the
initial clone unless you ask for it by passing the `--unversioned/-u`
flag.
## <a id="ait"></a>Autosync Is Intransitive
If you’re using Fossil in a truly distributed mode, rather than the
simple central-and-clones model that is more common, there may be no
single source of truth in the network because Fossil’s autosync feature
isn’t transitive.
That is, if you cloned from server A, and then you stand that up on a
server B, then if I clone from your server as my repository C, your changes to B
autosync up to A, but not down to me on C until I do something locally
that triggers autosync. The inverse is also true: if I commit something
on C, it will autosync up to B, but A won’t get a copy until someone on
B does something to trigger a sync there.
An easy way to run into this problem is to set up failover servers
`svr1` thru `svr3.example.com`, then set `svr2` and `svr3` up to sync
with the first. If all of the users normally clone from `svr1`, their
commits don’t get to `svr2` and `svr3` until something on one of the
servers pushes or pulls the changes down to the next server in the sync
chain.
Likewise, if `svr1` falls over and all of the users re-point their local
clones at `svr2`, then `svr1` later reappears, `svr1` is likely to
remain a stale copy of the old version of the repository until someone
causes it to sync with `svr2` or `svr3` to catch up again. And then if
you originally designed the sync scheme to treat `svr1` as the primary
source of truth, those users still syncing with `svr2` won’t have their
commits pushed up to `svr1` unless you’ve set up bidirectional sync,
rather than have the two backup servers do `pull` only.
# <a id="sync-solution"></a> Solution 1: Explicit Pulls
The following script solves most of the above problems for the use case
where you want a *nearly-complete* clone of the remote repository using nothing
but the normal Fossil sync protocol. It only does so if you are logged into
the remote as a user with Setup capability, however.
``` shell
#!/bin/sh
fossil sync --unversioned
fossil configuration pull all
fossil rebuild
```
The last step is needed to ensure that shunned artifacts on the remote
are removed from the local clone. The second step includes
`fossil conf pull shun`, but until those artifacts are actually rebuilt
out of existence, your backup will be “more than complete†in the sense
that it will continue to have information that the remote says should
not exist any more. That would be not so much a “backup†as an
“archive,†which might not be what you want.
# <a id="sql-solution"></a> Solution 2: SQL-Level Backup
The first method doesn’t get you a copy of the remote’s
[private branches][pbr], on purpose. It may also miss other info on the
remote, such as SQL-level customizations that the sync protocol can’t
see. (Some [ticket system customization][tkt] schemes rely on this ability, for example.) You can
solve such problems if you have access to the remote server, which
allows you to get a SQL-level backup by delegating handling of locking
and transaction isolation to
[the `backup` command][bu], allowing the user to safely back up an in-use
repository.
If you have SSH access to the remote server, something like this will work:
``` shell
#!/bin/bash
bf=repo-$(date +%Y-%m-%d).fossil
ssh example.com "cd museum ; fossil backup -R repo.fossil backups/$bf" &&
scp example.com:museum/backups/$bf ~/museum/backups
```
Beware that this method does not solve [the intransitive sync
problem](#ait), in and of itself: if you do a SQL-level backup of a
stale repo DB, you have a *stale backup!* You should therefore run this
on every node that may need to serve as a backup so that at least *one*
of the backups is also up-to-date.
# <a id="enc"></a> Encrypted Off-Site Backups
A useful refinement that you can apply to both methods above is
encrypted off-site backups. You may wish to store backups of your
repositories off-site on a service such as Dropbox, Google Drive, iCloud,
or Microsoft OneDrive, where you don’t fully trust the service not to
leak your information. This addition to the prior scripts will encrypt
the resulting backup in such a way that the cloud copy is a useless blob
of noise to anyone without the key:
```shell
iter=152830
pass="h8TixP6Mt6edJ3d6COaexiiFlvAM54auF2AjT7ZYYn"
gd="$HOME/Google Drive/Fossil Backups/$bf.xz.enc"
fossil sql -R ~/museum/backups/"$bf" .dump | xz -9 |
openssl enc -e -aes-256-cbc -pbkdf2 -iter $iter -pass pass:"$pass" -out "$gd"
```
If you’re adding this to the first script above, remove the
“`-R repo-name`†bit so you get a dump of the repository backing the
current working directory.
Change the `pass` value to some other long random string, and change the
`iter` value to something in the hundreds of thousands range. A good source for
the first is [here][grcp], and for the second, [here][rint].
You may find posts online written by people recommending millions of
iterations for PBKDF2, but they’re generally talking about this in the
context of memorizable passwords, where adding even one more character
to the password is a significant burden. Given our script’s purely
random maximum-length passphrase, there isn’t much more that increasing
the key derivation iteration count can do for us.
Conversely, if you were to reduce the passphrase to 41 characters, that
would drop the key strength by roughly 2â¶, being the entropy value per
character for using most of printable ASCII in our passphrase. To make
that lost strength up on the PBKDF2 end, you’d have to multiply your
iterations by 2â¶Â = 64 times. It’s easier to use a max-length passphrase
in this situation than get crazy with key derivation iteration counts.
(This, by the way, is why the example passphrase above is 42 characters:
with 6 bits of entropy per character, that gives you a key size of 252,
as close as we can get to our chosen encryption algorithm’s 256-bit key
size without going over. If it pleases you to give it 43 random
characters for a passphrase in order to pick up those last four bits of
security, you’re welcome to do so.)
Compressing the data before encrypting it removes redundancies that can
make decryption easier, and it results in a smaller backup than you get
with the previous script alone, at the expense of a lot of CPU time
during the backup. You may wish to switch to a less space-efficient
compression algorithm that takes less CPU power, such as [`lz4`][lz4].
Changing up the compression algorithm also provides some
security-thru-obscurity, which is useless on its own, but it *is* a
useful adjunct to strong encryption.
This requires OpenSSL 1.1 or higher. If you’re on 1.0 or older, you
won’t have the `-pbkdf2` and `-iter` options, and you may have to choose
a different cipher algorithm; both changes are likely to weaken the
encryption significantly, so you should install a newer version rather
than work around the lack of these features.
Beware that macOS ships a fork of OpenSSL called [LibreSSL][lssl] that
lacked this capability until Ventura (13.0). If you’re on Monterey (12)
or older, we recommend use of the [Homebrew][hb] OpenSSL package rather
than give up on the security afforded by use of configurable-iteration
PBKDF2. To avoid a conflict with the platform’s `openssl` binary,
Homebrew’s installation is [unlinked][hbul] by default, so you have to
give an explicit path to it, one of:
/usr/local/opt/openssl/bin/openssl ... # Intel x86 Macs
/opt/homebrew/opt/openssl/bin/openssl ... # ARM Macs (“Apple siliconâ€)

## <a id="rest"></a> Restoring From An Encrypted Backup
The “restore†script for the above fragment is basically an inverse of
it, but it’s worth showing it because there are some subtleties to take
care of. If all variables defined in earlier scripts are available, then
restoration is:
```
openssl enc -d -aes-256-cbc -pbkdf2 -iter $iter -pass pass:"$pass" -in "$gd" |
xz -d | fossil sql --no-repository ~/museum/restored-repo.fossil
```
We changed the `-e` to `-d` on the `openssl` command to get decryption,
and we changed the `-out` to `-in` so it reads from the encrypted backup
file and writes the result to stdout.
The decompression step is trivial.
The last change is tricky: we used `fossil sql` above to ensure that
we’re using the same version of SQLite to write the encrypted backup DB
as was used to maintain the repository. We must also do that on
restoration:
Fossil serves as a dogfooding project for SQLite,
often making use of the latest features, so it is quite likely that a given
random `sqlite3` binary in your `PATH` will be unable to understand the
file created by “`fossil sql .dump`â€! The tricky bit is, you can’t just
pipe the decrypted SQL dump into `fossil sql`, because on startup, Fossil
normally goes looking for tables created by `fossil init`, and it won’t
find them in a newly-created repo DB. We get around this by passing
the `--no-repository` flag, which suppresses this behavior. Doing it
this way saves you from needing to go and build a matching version of
`sqlite3` just to restore the backup.

<title>The Annotate Algorithm</title>
<h2>1.0 Introduction</h2>
The [/help?cmd=annotate|fossil annotate],
[/help?cmd=blame|fossil blame], and
[/help?cmd=praise|fossil praise] commands, and the
[/help?cmd=/annotate|/annotate],
[/help?cmd=/blame|/blame], and
[/help?cmd=/praise|/praise] web pages are all used to show the most
recent check-in that modified each line of a particular file.
This article overviews the algorithm used to compute the annotation
for a file in Fossil.
<h2>2.0 Algorithm</h2>
<ol type='1'>
<li>Locate the check-in that contains the file that is to be
annotated. Call this check-in C0.
<li>Find all direct ancestors of C0. A direct ancestor is the closure
of the primary parent of C0. Merged in branches are not part of
the direct ancestors of C0.
<li>Prune the list of ancestors of C0 so that it contains only
check-ins in which the file to be annotated was modified.
<li>Load the complete text of the file to be annotated from check-in C0.
Call this version of the file F0.
<li>Parse F0 into lines. Mark each line as "unchanged".
<li>For each ancestor of C0 on the pruned list (call the ancestor CX),
beginning with the most
recent ancestor and moving toward the oldest ancestor, do the
following steps:
<ol type='a'>
<li>Load the text for the file to be annotated as it existed in check-in CX.
Call this text FX.
<li>Compute a diff going from FX to F0.
<li>For each line of F0 that is changed in the diff and which was previously
marked "unchanged", update the mark to indicated that line
was modified by CX.
</ol>
<li>Show each line of F0 together with its change mark, appropriately
formatted.
</ol>
<h2>3.0 Discussion and Notes</h2>
The time-consuming part of this algorithm is step 6b - computing the
diff from all historical versions of the file to the version of the file
under analysis. For a large file that has many historical changes, this
can take several seconds. For this reason, the default
[/help?cmd=/annotate|/annotate] webpage only shows those lines that were
changed by the 20 most recent modifications to the file. This allows
the loop on step 6 to terminate after only 19 diffs instead of the hundreds
or thousands of diffs that might be required for a frequently modified file.
As currently implemented (as of 2015-12-12) the annotate algorithm does not
follow files across name changes. File name change information is
available in the database, and so the algorithm could be enhanced to follow
files across name changes by modifications to step 3.
Step 2 is interesting in that it is

# Is Fossil A Blockchain?
The Fossil version control system shares a lot of similarities with
other blockchain based technologies, but it also differs from the more common
sorts of blockchains. This document will discuss the term’s
applicability, so you can decide whether applying the term to Fossil
makes sense to you.
## The Dictionary Argument
The [Wikipedia definition of "blockchain"][bcwp] begins:
>
"A blockchain…is a growing list of records, called blocks, which are linked using
cryptography… Each block contains a cryptographic hash of the previous
block, a timestamp, and transaction data (generally represented as a Merkle tree)."
Point-for-point, Fossil follows this partial definition.
The blocks
are Fossil’s ["manifest" artifacts](./fileformat.wiki#manifest). Each
manifest has a cryptographically-strong [SHA-1] or [SHA-3] hash linking it to
one or more “parent†blocks. The manifest also contains a timestamp and
the transactional data needed to express a commit to the repository.
To traverse the Fossil repository from the tips of its [DAG] to the
root by following the parent hashes in each manifest is to traverse
a Merkle tree.
Every change in Fossil starts by adding one or more manifests to
the repository, extending this Merkle tree.

<a id="currency"></a>
## Cryptocurrency
Because blockchain technology was first popularized as Bitcoin, many
people associate the term with cryptocurrency. Fossil has nothing to do
with cryptocurrency, so a claim that “Fossil is a blockchain†may fail
to communicate the speaker’s concepts clearly due to conflation with
cryptocurrency.
Cryptocurrency has several features and requirements that Fossil doesn’t
provide, either because it doesn’t need them or because we haven’t
gotten around to creating the feature. Whether these are essential to
the definition of “blockchain†and thus disqualify Fossil as a blockchain
is for you to decide.
Cryptocurrencies must prevent three separate types of fraud to be useful:
* **Type 1** is modification of existing currency. To draw an analogy
to paper money, we wish to prevent someone from using green and
black markers to draw extra zeroes on a USÂ $10 bill so that it
claims to be a $100 bill.
* **Type 2** is creation of new fraudulent currency that will pass
in commerce. To extend our analogy, it is the creation of new
US $10 bills. There are two sub-types to this fraud. In terms of
our analogy, they are:
* **Type 2a**: copying an existing legitimate $10 bill<br><br>
* **Type 2b**: printing a new $10 bill that is unlike an existing
legitimate one, yet which will still pass in commerce
* **Type 3** is double-spending existing legitimate cryptocurrency.
There is no analogy in paper money due to its physical form; it is a
problem unique to digital currency due to its infinitely-copyable
nature.
How does all of this compare to Fossil?
1. <a id="signatures"></a>**Signatures.** Cryptocurrencies use a chain
of [digital signatures][dsig] to prevent Type 1 and Type 3 frauds. This
chain forms an additional link between the blocks, separate from the
hash chain that applies an ordering and lookup scheme to the blocks.
[_Blockchain: Simple Explanation_][bse] explains this “hash chainâ€
vs. “block chain†distinction in more detail.
These signatures prevent modification of the face value of each
transaction (Type 1 fraud) by ensuring that only the one signing a
new block has the private signing key that could change an issued
block after the fact.
The fact that these signatures are also *chained* prevents Type
3 frauds by making the *prior* owner of a block sign it over to
the new owner. To avoid an O(n²) auditing problem as a result,
cryptocurrencies add a separate chain of hashes to make checking
for double-spending quick and easy.
Fossil has [a disabled-by-default feature][cs] to call out to an
external copy of [PGP] or [GPG] to sign commit manifests before
inserting them into the repository. You can couple that with
a server-side [after-receive hook][arh] to reject unsigned commits.
Although there are several distinctions you can draw between the way
Fossil’s commit signing scheme works and the way block signing works
in cryptocurrencies, only one is of material interest for our
purposes here: Fossil commit signatures apply only to a single
commit. Fossil does not sign one commit over to the next “owner†of
that commit in the way that a blockchain-based cryptocurrency must
when transferring currency from one user to another, beacuse there
is no useful analog to the double-spending problem in Fossil. The
closest you can come to this is double-insert of commits into the
blockchain, which we’ll address shortly.
What Fossil commit signatures actually do is provide in-tree forgery
prevention, both Type 1 and Type 2. You cannot modify existing
commits (Type 1 forgery) because you do not have the original
committer’s private signing key, and you cannot forge new commits
attesting to come from some other trusted committer (Type 2) because
you don’t have any of their private signing keys, either.
Cryptocurrencies use the work problem to prevent Type 2
forgeries, but the application of that to Fossil is a matter we get
to [later](#work).
Although you have complete control over the contents of your local
Fossil repository clone, you cannot perform Type 1 forgery on its
contents short of executing a [preimage attack][prei] on the hash
algorithm. ([SHA3-256][SHA-3] by default in the current version of
Fossil.) Even if you could, Fossil’s sync protocol will prevent the
modification from being pushed into another repository: the remote
Fossil instance says, “I’ve already got that one, thanks,†and
ignores the push. Thus, short of breaking into the remote server
and modifying the repository in place, you couldn’t make use of
a preimage attack even if you had that power. Further, that would be an attack on the
server itself, not on Fossil’s data structures, so while it is
useful to think through this problem, it is not helpful in answering
our questions here.
The Fossil sync protocol’s duplication detection also prevents the closest analog to Type 3
frauds in Fossil: copying a commit manifest in your local repo clone
won’t result in a double-commit on sync.
In the absence of digital signatures, Fossil’s [RBAC system][caps]
restricts Type 2 forgery to trusted committers. Thus once again
we’re reduced to an infosec problem, not a data structure design
question.
(Inversely, enabling commit clearsigning is a good idea
if you have committers on your repo whom you don’t trust not to
commit Type 2 frauds. But let us be clear: your choice of setting
does not answer the question of whether Fossil is a blockchain.)
If Fossil signatures prevent Type 1 and Type 2 frauds, you
may wonder why they are not enabled by default. It is because
they are defense-in-depth measures, not the minimum sufficient
measures needed to prevent repository fraud, unlike the equivalent
protections in a cryptocurrency blockchain. Fossil provides its
primary protections through other means, so it doesn’t need to
mandate signatures.
Also, Fossil is not itself a [PKI], and there is no way for regular
users of Fossil to link it to a PKI, since doing so would likely
result in an unwanted [PII] disclosure. There is no email address
in a Fossil commit manifest that you could use to query one of the
public PGP keyservers, for example. It therefore becomes a local
policy matter as to whether you even *want* to have signatures,
because they’re not without their downsides.
2. <a id="work"></a>**Work Contests.** Cryptocurrencies prevent Type 2b forgeries
by setting up some sort of contest that ensures that new coins can come
into existence only by doing some difficult work task. This “miningâ€
activity results in a coin that took considerable work to create,
which thus has economic value by being a) difficult to re-create,
and b) resistant to [debasement][dboc].
Fossil repositories are most often used to store the work product of
individuals, rather than cryptocoin mining machines. There is
generally no contest in trying to produce the most commits. There
may be an implicit contest to produce the “best†commits, but that
is a matter of project management, not something that can be
automatically mediated through objective measures.
Incentives to commit to the repository come from outside of Fossil;
they are not inherent to its nature, as with cryptocurrencies.
Moreover, there is no useful sense in which we could say that one
commit “re-creates†another. Commits are generally products of
individual human intellect, thus necessarily unique in all but
trivial cases. This is foundational to copyright law.
3. <a id="lcr"></a>**Longest Chain Rule.** Cryptocurrencies generally
need some way to distinguish which blocks are legitimate and which
not. They do this in part by identifying the linear chain with the
greatest cumulative [work time](#work) as the legitimate chain. All
blocks not on that linear chain are considered “orphans†and are
ignored by the cryptocurrency software.
Its inverse is sometimes called the “51% attack†because a single
actor would have to do slightly more work than the entire rest of
the community using a given cryptocurrency in order for their fork
of the currency to be considered the legitimate fork. This argument
soothes concerns that a single bad actor could take over the
network.
The closest we can come to that notion in Fossil is the default
“trunk†branch, but there’s nothing in Fossil that delegitimizes
other branches just because they’re shorter, nor is there any way in
Fossil to score the amount of work that went into a commit. Indeed,
[forks and branches][fb] are *valuable and desirable* things in
Fossil.
This much is certain: Fossil is definitely not a cryptocurrency. Whether
this makes it “not a blockchain†is a subjective matter.

<a id="dlt"></a>
## Distributed Ledgers
Cryptocurrencies are an instance of [distributed ledger technology][dlt]. If
we can convince ourselves that Fossil is also a distributed
ledger, then we might think of Fossil as a peer technology,
having at least some qualifications toward being considered a blockchain.
A key tenet of DLT is that records be unmodifiable after they’re
committed to the ledger, which matches quite well with Fossil’s design
and everyday use cases. Fossil puts up multiple barriers to prevent
modification of existing records and injection of incorrect records.
Yet, Fossil also has [purge] and [shunning][shun]. Doesn’t that mean
Fossil cannot be a distributed ledger?
These features only remove existing commits from the repository. If you want a
currency analogy, they are ways to burn a paper bill or to melt a [fiat
coin][fc] down to slag. In a cryptocurrency, you can erase your “walletâ€
file, effectively destroying money in a similar way. These features
do not permit forgery of either type described above: you can’t use them
to change the value of existing commits (Type 1) or add new commits to
the repository (Type 2).
What if we removed those features from Fossil, creating an append-only
Fossil variant? Is it a DLT then? Arguably still not, because [today’s Fossil
is an AP-mode system][ctap], which means
there can be no guaranteed consensus on the content of the ledger at any
given time. An AP-mode accounts receivable system would allow
different bottom-line totals at different sites, because you’ve
cast away “C†to get AP-mode operation. (See the prior link or
[Wikipedia’s article on the CAP theorem][cap] if you aren’t following
this terminology.)
By the same token, you cannot guarantee that the command
“`fossil info tip`†gives the same result everywhere. You would need to
recast Fossil as a CA or CP-mode system to solve that.
(Everyone not
partitioned away from the majority of the network at any rate, in the CP
case.)
What are the prospects for CA-mode or CP-mode Fossil? [We don’t want
CA-mode Fossil][ctca], but [CP-mode could be useful][ctcp]. Until the latter
exists, this author believes Fossil is not a distributed ledger in a
technologically defensible sense.
The most common technologies answering to the label “blockchain†are all
DLTs, so if Fossil is not a DLT, then it is not a blockchain in that
sense.

<a id="dpc"></a>
## Distributed Partial Consensus
If we can’t get DLT, can we at least get some kind of distributed
consensus at the level of individual Fossil’s commits?
Many blockchain based technologies have this property: given some
element of the blockchain, you can make certain proofs that it either is
a legitimate part of the whole blockchain, or it is not.
Unfortunately, this author doesn’t see a way to do that with Fossil.
Given only one “block†in Fossil’s putative “blockchain†— a commit, in
Fossil terminology — all you can prove is whether it is internally
consistent, that it is not corrupt. That then points you at the parent(s) of that
commit, which you can repeat the exercise on, back to the root of the
DAG. This is what the enabled-by-default [`repo-cksum` setting][rcks]
does.
If cryptocurrencies worked this way, you wouldn’t be able to prove that
a given cryptocoin was legitimate without repeating the proof-of-work
calculations for the entire cryptocurrency scheme! Instead, you only
need to check a certain number of signatures and proofs-of-work in order
to be reasonably certain that you are looking at a legitimate section of
the whole blockchain.
What would it even mean to prove that a given Fossil commit “*belongs*â€
to the repository you’ve extracted it from? For a software project,
isn’t that tantamount to automatic code review, where the server would
be able to reliably accept or reject a commit based solely on its
content? That sounds nice, but this author believes we’ll need to invent
[AGI] first.
A better method to provide distributed consensus for Fossil would be to
rely on the *natural* intelligence of its users: that is, distributed
commit signing, so that a commit is accepted into the blockchain only
once some number of users countersign it. This amounts to a code review
feature, which Fossil doesn’t currently have.
Solving that problem basically requires solving the [PKI] problem first,
since you can’t verify the proofs of these signatures if you can’t first
prove that the provided signatures belong to people you trust. This is a
notoriously hard problem in its own right.
A future version of Fossil could instead provide [consensus in the CAP
sense][ctcp]. For instance, you could say that if a quorum of servers
all have a given commit, it “belongs.†Fossil’s strong hashing tech
would mean that querying whether a given commit is part of the
“blockchain†would be as simple as going down the list of servers and
sending each an HTTP GET `/info` query for the artifact ID, concluding
that the commit is legitimate once you get enough HTTP 200 status codes back. All of this is
hypothetical, because Fossil doesn’t do this today.

<a id="anon"></a>
## Anonymity
Many blockchain based technologies go to extraordinary lengths to
allow anonymous use of their service.
As typically configured, Fossil does not: commits synced between servers
always at least have a user name associated with them, which the remote
system must accept through its [RBAC system][caps]. That system can run
without having the user’s email address, but it’s needed if [email
alerts][alert] are enabled on the server. The remote server logs the IP
address of the commit for security reasons. That coupled with the
timestamp on the commit could sufficiently deanonymize users in many
common situations.
It is possible to configure Fossil so it doesn’t do this:
* You can give [Write capability][capi] to user category “nobody,†so
that anyone that can reach your server can push commits into its
repository.
* You could give that capability to user category “anonymous†instead,
which requires that the user log in with a CAPTCHA, but which doesn’t
require that the user otherwise identify themselves.
* You could enable [the `self-register` setting][sreg] and choose not to
enable [commit clear-signing][cs] so that anonymous users could push
commits into your repository under any name they want.
On the server side, you can also [scrub] the logging that remembers
where each commit came from.
Commit source info isn’t transmitted from the remote server on clone or pull:
the size of the `rcvfrom` table after initial clone is 1, containing
only the remote server’s IP address. On each pull containing new
artifacts, your local `fossil` instance adds another entry to this
table, likely with the same IP address unless the server has moved or
you’re using [multiple remotes][mrep]. This table is far more
interesting on the server side, containing the IP addresses of all
contentful pushes; thus [the `scrub` command][scrub].
Because Fossil doesn’t
remember IP addresses in commit manifests or require commit signing, it
allows at least *pseudonymous* commits. When someone clones a remote
repository, they don’t learn the email address, IP address, or any other
sort of [PII] of prior committers, on purpose.
Some people say that private, permissioned blockchains (as you may
imagine Fossil to be) are inherently problematic by the very reason that
they don’t bake anonymous contribution into their core. The very
existence of an RBAC is a moving piece that can break. Isn’t it better,
the argument goes, to have a system that works even in the face of
anonymous contribution, so that you don’t need an RBAC? Cryptocurrencies
do this, for example: anyone can “mine†a new coin and push it into the
blockchain, and there is no central authority restricting the transfer
of cryptocurrency from one user to another.
We can draw an analogy to encryption, where an algorithm is
considered inherently insecure if it depends on keeping any information
from an attacker other than the key. Encryption schemes that do
otherwise are derided as “security through obscurity.â€
You may be wondering what any of this has to do with whether Fossil is a
blockchain, but that is exactly the point: all of this is outside
Fossil’s core hash-chained repository data structure. If you take the
position that you don’t have a “blockchain†unless it allows anonymous
contribution, with any needed restrictions provided only by the very
structure of the managed data, then Fossil does not qualify.
Why do some people care about this distinction? Consider Bitcoin,
wherein an anonymous user cannot spam the blockchain with bogus coins
because its [proof-of-work][pow] protocol allows such coins to be
rejected immediately. There is no equivalent in Fossil: it has no
technology that allows the receiving server to look at the content of a
commit and automatically judge it to be “good.†Fossil relies on its
RBAC system to provide such distinctions: if you have a commit bit, your
commits are *ipso facto* judged “good,†insofar as any human work
product can be so judged by a blob of compiled C code. This takes us
back to the [digital ledger question](#dlt), where we can talk about
what it means to later correct a bad commit that got through the RBAC
check.
We may be willing to accept pseudonymity, rather than full anonymity.
If we configure Fossil as above, either bypassing the RBAC or abandoning
human control over it, scrubbing IP addresses, etc., is it then a public
permissionless blockchain in that sense?
We think not, because there is no [longest chain rule](#lcr) or anything
like it in Fossil.
For a fair model of how a Fossil repository might behave under such
conditions, consider GitHub: here one user can fork another’s repository
and make an arbitrary number of commits to their public fork. Imagine
this happens 10 times. How does someone come along later and
*automatically* evaluate which of the 11 forks of the code (counting the
original repository among their number) is the “best†one? For a
computer software project, the best we could do to approximate this
devolves to a [software project cost estimation problem][scost]. These
methods are rather questionable in their own right, being mathematical
judgement values on human work products, but even if we accept their
usefulness, then we still cannot say which fork is better based solely
on their scores under these metrics. We may well prefer to use the fork
of a software program that took *less* effort, being smaller, more
self-contained, and with a smaller attack surface.

# Conclusion
This author believes it is technologically indefensible to call Fossil a
“blockchain†in any sense likely to be understood by a majority of those
you’re communicating with. Using a term in a nonstandard way just because you can
defend it means you’ve failed any goal that requires clear communication.
The people you’re communicating your ideas to must have the
same concept of the terms you use.
What term should you use instead? Fossil stores a DAG of hash-chained
commits, so an indisputably correct term is a [Merkle tree][mt], named
after [its inventor][drrm]. You could also use the more generic term
“hash tree.â€
Fossil is a technological peer to many common sorts of blockchain
technology. There is a lot of overlap in concepts and implementation
details, but when speaking of what most people understand as
“blockchain,†Fossil is not that.

<title>Branching, Forking, Merging, and Tagging</title>
<h2>Background</h2>
In a simple and perfect world, the development of a project would proceed
linearly, as shown in Figure 1.
<verbatim type="pikchr center toggle">

Each circle represents a check-in. For the sake of clarity, the check-ins
are given small consecutive numbers. In a real system, of course, the
check-in numbers would be long hexadecimal hashes since it is not possible
to allocate collision-free sequential numbers in a distributed system.
But as sequential numbers are easier to read, we will substitute them for
the long hashes in this document.
The arrows in Figure 1 show the evolution of a project. The initial
check-in is 1. Check-in 2 is derived from 1. In other words, check-in 2
was created by making edits to check-in 1 and then committing those edits.
We say that 2 is a <i>child</i> of 1
and that 1 is a <i>parent</i> of 2.
Check-in 3 is derived from check-in 2, making
3 a child of 2. We say that 3 is a <i>descendant</i> of both 1 and 2 and that 1
and 2 are both <i>ancestors</i> of 3.
<h2 id="dag">DAGs</h2>
The graph of check-ins is a
[http://en.wikipedia.org/wiki/Directed_acyclic_graph | directed acyclic graph],
commonly shortened to <i>DAG</i>. Check-in 1 is the <i>root</i> of the DAG
since it has no ancestors. Check-in 4 is a <i>leaf</i> of the DAG since
it has no descendants. (We will give a more precise definition later of
"leaf.")
Alas, reality often interferes with the simple linear development of a
project. Suppose two programmers make independent modifications to check-in 2.
After both changes are committed, the check-in graph looks like Figure 2:
<verbatim type="pikchr center toggle">

</verbatim>
The graph in Figure 2 has two leaves: check-ins 3 and 4. Check-in 2 has
two children, check-ins 3 and 4. We call this state a <i>fork</i>.
Fossil tries to prevent forks, primarily through its
"[./concepts.wiki#workflow | autosync]" mechanism.
Suppose two programmers named Alice and
Bob are each editing check-in 2 separately. Alice finishes her edits
and commits her changes first, resulting in check-in 3. When Bob later
attempts to commit his changes, Fossil verifies that check-in 2 is still
a leaf. Fossil sees that check-in 3 has occurred and aborts Bob's commit
attempt with a message "would fork." This allows Bob to do a "fossil
update" to pull in Alice's changes, merging them into his own
changes. After merging, Bob commits check-in 4 as a child of check-in 3.
The result is a linear graph as shown in Figure 1. This is how CVS
works. This is also how Fossil works in autosync mode.
But perhaps Bob is off-network when he does his commit, so he has no way
of knowing that Alice has already committed her changes. Or, it could
be that Bob has turned off "autosync" mode in Fossil. Or, maybe Bob
just doesn't want to merge in Alice's changes before he has saved his
own, so he forces the commit to occur using the "--allow-fork" option to
the <b>[/help?cmd=commit | fossil commit]</b> command. For any of these
reasons, two commits against check-in 2 have occurred, so the DAG now
has two leaves.
In such a condition, a person working with this repository has a
dilemma: which version of the project is the "latest" in the sense of
having the most features and the most bug fixes? When there is more
than one leaf in the graph, you don't really know, which is why we
would ideally prefer to have linear check-in graphs.
Fossil resolves such problems using the check-in time on the leaves to
decide which leaf to use as the parent of new leaves. When a branch is
forked as in Figure 2, Fossil will choose check-in 4 as the parent for a
later check-in 5, but <i>only</i> if it has sync'd that check-in down
into the local repository. If autosync is disabled or the user is
off-network when that fifth check-in occurs so that check-in 3 is the
latest on that branch at the time within that clone of the repository,
Fossil will make check-in 3 the parent of check-in 5! We show practical
consequences of this [#bad-fork | later in this article].
Fossil also uses a forked branch's leaf check-in timestamps when
checking out that branch: it gives you the fork with the latest
check-in, which in turn selects which parent your next check-in will be
a child of. This situation means development on that branch can fork
into two independent lines of development, based solely on which branch
tip is newer at the time the next user starts his work on it.
Because of these potential problems, we strongly recommend that you do
not intentionally create forks on long-lived shared working branches
with "--allow-fork". (Prime example: trunk.) The inverse case —
intentional forks on short-lived single-developer branches — is far
easier to justify, since presumably the lone developer is never confused
about why there are two or more leaves on that branch. Further
justifications for intentional forking are [#forking | given below].
Let us return to Figure 2. To resolve such situations before they can
become a real problem, Alice can use the <b>[/help?cmd=merge | fossil
merge]</b> command to merge Bob's changes into her local copy of
check-in 3. Without arguments, that command merges all leaves on the
current branch. Alice can then verify that the merge is sensible and if
so, commit the results as check-in 5. This results in a DAG as shown in
Figure 3.

Check-in 5 is a child of check-in 3 because it was created by editing
check-in 3, but since check-in 5 also inherits the changes from check-in 4 by
virtue of the merge, we say that check-in 5 is a <i>merge child</i>
of check-in 4 and that it is a <i>direct child</i> of check-in 3.
The graph is now back to a single leaf, check-in 5.
We have already seen that if Fossil is in autosync mode then Bob would
have been warned about the potential fork the first time he tried to
commit check-in 4. If Bob had updated his local check-out to merge in
Alice's check-in 3 changes, then committed, the fork would have
never occurred. The resulting graph would have been linear, as shown
in Figure 1.
Realize that the graph of Figure 1 is a subset of Figure 3. If you hold your
hand over the â‘£ in Figure 3, it looks
exactly like Figure 1 except that the leaf has a different check-in
number. That is just a notational difference: the two check-ins
have exactly the same content.
Inversely, Figure 3 is a
superset of Figure 1. The check-in 4 of Figure 3 captures additional
state which is omitted from Figure 1. Check-in 4 of Figure 3 holds a
copy of Bob's local checkout before he merged in Alice's changes. That
snapshot of Bob's changes, which is independent of Alice's changes, is
omitted from Figure 1.
Some people say that the development approach taken in
Figure 3 is better because it preserves this extra intermediate state.
Others say that the approach taken in Figure 1 is better because it is
much easier to visualize linear development and because the
merging happens automatically instead of as a separate manual step. We
will not take sides in that debate. We will simply point out that
Fossil enables you to do it either way.
<h2 id="branching">The Alternative to Forking: Branching</h2>
Having more than one leaf in the check-in DAG is called a "fork." This
is usually undesirable and either avoided entirely,
as in Figure 1, or else quickly resolved as shown in Figure 3.
But sometimes, one does want to have multiple leaves. For example, a project
might have one leaf that is the latest version of the project under
development and another leaf that is the latest version that has been
tested.
When multiple leaves are desirable, we call this <i>branching</i>
instead of <i>forking</i>:
Figure 4 shows an example of a project where there are two branches, one
for development work and another for testing.

Figure 4 diagrams the following scenario: the project starts and
progresses to a point where (at check-in 2)
it is ready to enter testing for its first release.
In a real project, of course, there might be hundreds or thousands of
check-ins before a project reaches this point, but for simplicity of
presentation we will say that the project is ready after check-in 2.
The project then splits into two branches that are used by separate
teams. The testing team, using the blue branch, finds and fixes a few
bugs with check-ins 6 and 9. Meanwhile, the development
team, working on the top uncolored branch,
is busy adding features for the second
release. Of course, the development team would like to take advantage of
the bug fixes implemented by the testing team, so periodically the
changes in the test branch are merged into the dev branch. This is
shown by the dashed merge arrows between check-ins 6 and 7 and between
check-ins 9 and 10.
In both Figures 2 and 4, check-in 2 has two children. In Figure 2,
we call this a "fork." In diagram 4, we call it a "branch." What is
the difference? As far as the internal Fossil data structures are
concerned, there is no difference. The distinction is in the intent.
In Figure 2, the fact that check-in 2 has multiple children is an
accident that stems from concurrent development. In Figure 4, giving
check-in 2 multiple children is a deliberate act. To a good
approximation, we define forking to be by accident and branching to
be by intent. Apart from that, they are the same.
When the fork is intentional, it helps humans to understand what is
going on if we <i>name</i> the forks. This is not essential to Fossil's
internal data model, but humans have trouble working with long-lived
branches identified only by the commit ID currently at its tip, being a
long string of hex digits. Therefore, Fossil conflates two concepts:
branching as intentional forking and the naming of forks as branches.
They are in fact separate concepts, but since Fossil is intended to be
used primarily by humans, we combine them in Fossil's human user
interfaces.
<p class="blockquote">
<b>Key Distinction:</b> A branch is a <i>named, intentional</i> fork.
</p>
Unnamed forks <i>may</i> be intentional, but most of the time, they're
accidental and left unnamed.
Fossil offers two primary ways to create named, intentional forks,
a.k.a. branches. First:
<pre>
$ fossil commit --branch my-new-branch-name
</pre>
This is the method we recommend for most cases: it creates a branch as
part of a check-in using the version in the current checkout directory
as its basis. (This is normally the tip of the current branch, though
it doesn't have to be. You can create a branch from an ancestor check-in
on a branch as well.) After making this branch-creating
check-in, your local working directory is switched to that branch, so
that further check-ins occur on that branch as well, as children of the
tip check-in on that branch.
The second, more complicated option is:
<pre>
$ fossil branch new my-new-branch-name trunk
$ fossil update my-new-branch-name
$ fossil commit
</pre>
Not only is this three commands instead of one, the first of which is
longer than the entire simpler command above, you must give the second command
before creating any check-ins, because until you do, your local working
directory remains on the same branch it was on at the time you issued
the command, so that the commit would otherwise put the new material on
the original branch instead of the new one.
In addition to those problems, the second method is a violation of the
[https://en.wikipedia.org/wiki/You_aren%27t_gonna_need_it|YAGNI
Principle]. We recommend that you wait until you actually need the
branch before you create it using the first command above.
The "trunk" is just another named branch in Fossil. It is simply
the default branch name for the first check-in and every check-in made as
one of its direct descendants. It is special only in that it is Fossil's
default when it has no better idea of which branch you mean.
<h2 id="forking">Justifications For Forking</h2>
The primary cases where forking is justified over branching are all when
it is done purely in software in order to avoid losing information:
<ol>
<li><p id="offline">By Fossil itself when two users check in children to the same
leaf of a branch, as in Figure 2.
<br><br>
If the fork occurs because
autosync is disabled on one or both of the repositories or because
the user doing the check-in has no network connection at the moment
of the commit, Fossil has no way of knowing that it is creating a
fork until the two repositories are later synchronized.</p></li>
<li><p id="dist-clone">By Fossil when the cloning hierarchy is more
than 2 levels deep.
<br><br>
[./sync.wiki|Fossil's synchronization protocol] is a two-party
negotiation; syncs don't automatically propagate up the clone tree
beyond that. Because of that, if you have a master repository and
Alice clones it, then Bobby clones from Alice's repository, a
check-in by Bobby that autosyncs with Alice's repo will <i>not</i>
also autosync with the master repo. The master doesn't get a copy of
Bobby's check-in until Alice <i>separately</i> syncs with the master.
If Carol cloned from the master repo and checks something in that
creates a fork relative to Bobby's check-in, the master repo won't
know about that fork until Alice syncs her repo with the master.
Even then, realize that Carol still won't know about the fork until
she subsequently syncs with the master repo.
<br><br>
One way to deal with this is to just accept it as a fact of using a
[https://en.wikipedia.org/wiki/Distributed_version_control|Distributed
Version Control System] like Fossil.
<br><br>
Another option, which we recommend you consider carefully, is to
make it a local policy that check-ins be made only directly against the master
repo or one of its immediate child clones so that the autosync
algorithm can do its job most effectively. Any clones deeper than
that should be treated as read-only and thus get a copy of the new
state of the world only once these central repos have negotiated
that new state. This policy avoids a class of inadvertent fork you
might not need to tolerate. Since [#bad-fork|forks on long-lived
shared working branches can end up dividing a team's development
effort], a team may easily justify this restriction on distributed
cloning.</p></li>
<li><p id="automation">You've automated Fossil, so you use
<b>fossil commit --allow-fork</b> commands to prevent Fossil from
refusing the check-in simply because it would create a fork.
<br><br>
If you are writing such a tool — e.g. a shell script to make
multiple manipulations on a Fossil repo — it's better to make it
smart enough to detect this condition and cope with it, such as
by making a call to <b>[/help?cmd=update | fossil update]</b>
and checking for a merge conflict. That said, if the alternative is
losing information, you may feel justified in creating forks that an
interactive user must later manually clean up with <b>fossil merge</b>
commands.</p></li>
</ol>
That leaves only one case where we can recommend use of "--allow-fork"
by interactive users: when you're working on a personal branch so that
creating a dual-tipped branch isn't going to cause any other user an
inconvenience or risk [#bad-fork | inadvertently forking the development
effort]. In such a case, the lone developer working on that branch is
not confused, since the fork in development is intentional. Sometimes it
simply makes no sense to bother creating a name, cluttering the global
branch namespace, simply to convert an intentional fork into a "branch."
This is especially the case when the fork is short-lived.
There's a common generalization of that case: you're a solo developer,
so that the problems with branching vs forking simply don't matter. In
that case, feel free to use "--allow-fork" as much as you like.
<h2 id="fix">Fixing Forks</h2>
If your local checkout is on a forked branch, you can usually fix a fork
automatically with:
<pre>
$ fossil merge
</pre>
Normally you need to pass arguments to <b>fossil merge</b> to tell it
what you want to merge into the current basis view of the repository,
but without arguments, the command seeks out and fixes forks.
<h2 id="tags">Tags And Properties</h2>
Tags and properties are used in Fossil to help express the intent, and
thus to distinguish between forks and branches. Figure 5 shows the
same scenario as Figure 4 but with tags and properties added:

A <i>tag</i> is a name that is attached to a check-in. A
<i>property</i> is a name/value pair. Internally, Fossil implements
tags as properties with a NULL value. So, tags and properties really
are much the same thing, and henceforth we will use the word "tag"
to mean either a tag or a property.
A tag can be a one-time tag, a propagating tag or a cancellation tag.
A one-time tag only applies to the check-in to which it is attached. A
propagating tag applies to the check-in to which it is attached and also
to all direct descendants of that check-in. A <i>direct descendant</i>
is a descendant through direct children. Tag propagation does not
cross merges. Tag propagation also stops as soon
as it encounters another check-in with the same tag. A cancellation tag
is attached to a single check-in in order to either override a one-time
tag that was previously placed on that same check-in, or to block
tag propagation from an ancestor.
The initial check-in of every repository has two propagating tags. In
Figure 5, that initial check-in is check-in 1. The <b>branch</b> tag
tells (by its value) what branch the check-in is a member of.
The default branch is called "trunk." All tags that begin with "<b>sym-</b>"
are symbolic name tags. When a symbolic name tag is attached to a
check-in, that allows you to refer to that check-in by its symbolic
name rather than by its hexadecimal hash name. When a symbolic name
tag propagates (as does the <b>sym-trunk</b> tag) then referring to that
name is the same as referring to the most recent check-in with that name.
Thus the two tags on check-in 1 cause all descendants to be in the
"trunk" branch and to have the symbolic name "trunk."
Check-in 4 has a <b>branch</b> tag which changes the name of the branch
to "test." The branch tag on check-in 4 propagates to check-ins 6 and 9.
But because tag propagation does not follow merge links, the <b>branch=test</b>
tag does not propagate to check-ins 7, 8, or 10. Note also that the
<b>branch</b> tag on check-in 4 blocks the propagation of <b>branch=trunk</b>
so that it cannot reach check-ins 6 or 9. This causes check-ins 4, 6, and
9 to be in the "test" branch and all others to be in the "trunk" branch.
Check-in 4 also has a <b>sym-test</b> tag, which gives the symbolic name
"test" to check-ins 4, 6, and 9. Because tags do not propagate across
merges, check-ins 7, 8, and 10 do not inherit the <b>sym-test</b> tag and
are hence not known by the name "test."
To prevent the <b>sym-trunk</b> tag from propagating from check-in 1
into check-ins 4, 6, and 9, there is a cancellation tag for
<b>sym-trunk</b> on check-in 4. The net effect is that
check-ins on the trunk go by the symbolic name of "trunk" and check-ins
on the test branch go by the symbolic name "test."
The <b>bgcolor=blue</b> tag on check-in 4 causes the background color
of timelines to be blue for check-in 4 and its direct descendants.
Figure 5 also shows two one-time tags on check-in 9. (The diagram does
not make a graphical distinction between one-time and propagating tags.)
The <b>sym-release-1.0</b> tag means that check-in 9 can be referred to
using the more meaningful name "release-1.0." The <b>closed</b> tag means
that check-in 9 is a "closed leaf." A closed leaf is a leaf that should
never have direct children.
<h2 id="bad-fork">How Can Forks Divide Development Effort?</h2>
[#dist-clone|Above], we stated that forks carry a risk that development
effort on a branch can be divided among the forks. It might not be
immediately obvious why this is so. To see it, consider this swim lane

This is a happy, cooperating team. That is an important restriction on
our example, because you must understand that this sort of problem can
arise without any malice, selfishness, or willful ignorance in sight.
All users on this diagram start out with the same view of the
repository, cloned from the same master repo, and all of them are
working toward their shared vision of a unified future.
All users, except possibly Alan, start out with the same two initial
check-ins in their local working clones, 1 & 2. It might be that Alan
starts out with only check-in 1 in his local clone, but we'll deal with
that detail later.
It doesn't matter which branch this happy team is working on, only that
our example makes the most sense if you think of it as a long-lived shared
working branch like trunk. Each user makes
only one check-in, shaded light gray in the diagram.
<h3 id="bf-alan">Step 1: Alan</h3>
Alan sets the stage for this problem by creating a
fork from check-in 1 as check-in 3. How and why Alan did this doesn't
affect what happens next, though we will walk through the possible cases
and attempt to assign blame [#post-mortem|in the <i>post mortem</i>].
For now, you can assume that Alan did this out of unavoidable ignorance.
<h3 id="bf-betty">Step 2: Betty</h3>
Because Betty's local clone is autosyncing with
the same upstream repository as Alan's clone, there are a number of ways
she can end up seeing Alan's check-in 3 as the latest on that branch:
<ol>
<li><p>The working check-out directory she's using at the moment was
on a different branch at the time Alan made check-in 3, so Fossil
sees that as the tip at the time she switches her working directory
to that branch with a <b>fossil update $BRANCH</b> command. (There is an
implicit autosync in that command, if the option was enabled at the
time of the update.)</p></li>
<li><p>The same thing, only in a fresh checkout directory with a
<b>[/help?cmd=open | fossil open $REPO $BRANCH]</b> command.</p></li>
<li><p>Alan makes his check-in 3 while Betty has check-in 1 or 2 as
the tip in her local clone, but because she's working with an
autosync'd connection to the same upstream repository as Alan, on
attempting what will become check-in 4, she gets the "would fork"
message from <b>fossil commit</b>, so she dutifully updates her clone
and tries again, moving her work to be a child of the new tip,
check-in 3. (If she doesn't update, she creates a <i>second</i>
fork, which simply complicates matters beyond what we need here for
our illustration.)</p></li>
</ol>
For our purposes here, it doesn't really matter which one happened. All
that matters is that Alan's check-in 3 becomes the parent of Betty's
check-in 4 because it was the newest tip of the working branch at the
time Betty does her check-in.
<h3 id="bf-charlie">Step 3: Charlie</h3>
Meanwhile, Charlie went offline after syncing
his repo with check-in 2 as the latest on that branch. When he checks
his changes in, it is as a child of 2, not of 4, because Charlie doesn't
know about check-ins 3 & 4 yet. He does this at an absolute wall clock
time <i>after</i> Alan and Betty made their check-ins, so when Charlie
comes back online and pushes his check-in 5 to the master repository and
learns about check-ins 3 and 4 during Fossil sync, Charlie inadvertently
revives the other side of the fork.
<h3 id="bf-darlene">Step 4: Darlene</h3>
Darlene sees all of this, because she joins in
on the work on this branch after Alan, Betty, and Charlie made their
check-ins and pushed them to the master repository. She's taking one of
the same three steps as we [#bf-betty|outlined for Betty above].
Regardless of her path to this view, it happens after Charlie pushed his
check-in 5 to the master repo, so Darlene sees that as the latest on the
branch, causing her work to be saved as a child of check-in 5, not of
check-in 4, as it would if Charlie didn't come back online and sync
before Darlene started work on that branch.
<h3 id="post-mortem">Post Mortem</h3>
The end result of all of this is that even though everyone makes only one check-in
and no one disables autosync without genuine need,
half of the check-ins end up on one side of the fork and half on
the other.
A future user — his mother calls him Edward, but please call him Eddie —
can then join in on the work on this branch and end up on <i>either</i> side of
the fork. If Eddie joins in with the state of the repository as drawn
above, he'll end up on the top side of the fork, because check-in 6 is
the latest, but if Alan or Betty makes a seventh check-in to that branch
first, it will be as a child of check-in 4 since that's the version in
their local check-out directories. Since that check-in 7 will then be the latest,
Eddie will end up on the bottom side of the fork instead.
In all of this, realize that neither side of the fork is obviously
"correct." Every participant was doing the right thing by their own
lights at the time they made their lone check-in.
Who, then, is to blame?
We can only blame the consequences of creating the fork on Alan if he
did so on purpose, as by passing "--allow-fork" when creating a check-in
on a shared working branch. Alan might have created it inadvertently by
going offline while check-in 1 was the tip of the branch in his local
clone, so that by the time he made his check-in 3, check-in 2 had
arrived at the shared parent repository from someone else. (Francine?)
When Alan rejoins the network and does an autosync, he learns about
check-in 2. Since his #3 is already checked into his local clone because
autosync was off or blocked, the sync creates an unavoidable fork. We
can't blame either Alan or Francine here: they were both doing the right
thing given their imperfect view of the state of the global situation.
The same is true of Betty, Charlie, and Darlene. None of them tried to
create a fork, and none of them chose a side in this fork to participate
in. They just took Fossil's default and assumed it was correct.
The only blame I can assign here is on any of these users who believed
forks couldn't happen before this did occur, and I blame them only for
their avoidable ignorance. (You, dear reader, have been ejected from
that category by reading this very document.) Any time someone can work
without getting full coordination from every other clone of the repo,
forks are possible. Given enough time, they're all but inevitable. This
is a general property of DVCSes, not just of Fossil.
This sort of consequence is why forks on shared working branches are
bad, which is why [./concepts.wiki#workflow|Fossil tries so hard to avoid them], why it warns you
about it when they do occur, and why it makes it relatively [#fix|quick and
painless to fix them] when they do occur.
<h2>Review Of Terminology</h2>
<dl>
<dt><b>Branch</b></dt>
<dd><p>A branch is a set of check-ins with the same value for their
"branch" property.</p></dd>
<dt><b>Leaf</b></dt>
<dd><p>A leaf is a check-in with no children in the same branch.</p></dd>
<dt><b>Closed Leaf</b></dt>
<dd><p>A closed leaf is any leaf with the <b>closed</b> tag. These leaves
are intended to never be extended with descendants and hence are omitted
from lists of leaves in the command-line and web interface.</p></dd>
<dt><b>Open Leaf</b></dt>
<dd><p>A open leaf is a leaf that is not closed.</p></dd>
<dt><b>Fork</b></dt>
<dd><p>A fork is when a check-in has two or more direct (non-merge)
children in the same branch.</p></dd>
<dt><b>Branch Point</b></dt>
<dd><p>A branch point occurs when a check-in has two or more direct (non-merge)
children in different branches. A branch point is similar to a fork,
except that the children are in different branches.</p></dd>
</dl>
Check-in 4 of Figure 3 is not a leaf because it has a child (check-in 5)
in the same branch. Check-in 9 of Figure 5 also has a child (check-in 10)
but that child is in a different branch, so check-in 9 is a leaf. Because
of the <b>closed</b> tag on check-in 9, it is a closed leaf.
Check-in 2 of Figure 3 is considered a "fork"
because it has two children in the same branch. Check-in 2 of Figure 5
also has two children, but each child is in a different branch, hence in
Figure 5, check-in 2 is considered a "branch point."
<h2>Differences With Other DVCSes</h2>
<h3 id="single">Single DAG</h3>
Fossil keeps all check-ins on a single DAG. Branches are identified with
tags. This means that check-ins can be freely moved between branches
simply by altering their tags.
Most other DVCSes maintain a separate DAG for each branch.
<h3 id="unique">Branch Names Need Not Be Unique</h3>
Fossil does not require that branch names be unique, as in some VCSes,
most notably Git. Just as with unnamed branches (which we call forks)
Fossil resolves such ambiguities using the timestamps on the latest
check-in in each branch. If you have two branches named "foo" and you say
<b>fossil update foo</b>, you get the tip of the "foo" branch with the most
recent check-in.
This fact is helpful because it means you can reuse branch names, which
is especially useful with utility branches. There are several of these
in the SQLite and Fossil repositories: "broken-build," "declined,"
"mistake," etc. As you might guess from these names, such branch names
are used in renaming the tip of one branch to shunt it off away from the
mainline of that branch due to some human error. (See
<b>[/help?cmd=amend | fossil
amend]</b> and the Fossil UI check-in amendment features.) This is a
workaround for Fossil's [./shunning.wiki|normal inability to forget
history]: we usually don't want to actually <i>remove</i> history, but
would like to sometimes set some of it aside under a new label.
Because some VCSes can't cope with duplicate branch names, Fossil
collapses such names down on export using the same time stamp based
arbitration logic, so that only the branch with the newest check-in gets
the branch name in the export.
All of the above is true of tags in general, not just branches.

<title>Compiling and Installing Fossil</title>
<h2>0.0 Using A Pre-compiled Binary</h2>
[/uv/download.html|Pre-compiled binaries] are available for recent
releases. Just download
the appropriate executable for your platform
and put it on your $PATH.
To uninstall, simply delete the executable.
To upgrade from an older release, just overwrite the older binary with
the newer one.
For details about how those binaries are built, see
[/wiki?name=Release+Build+How-To | the Release Build How-To wiki page].
<h2>0.1 Executive Summary</h2>
Building and installing is very simple. Three steps:
<ol>
<li> Download and unpack a source tarball or ZIP.
<li> <b>./configure; make</b>
<li> Move the resulting "fossil" or "fossil.exe" executable to someplace on
your $PATH.
</ol>
<hr>
<h2>1.0 Obtaining The Source Code</h2>
Fossil is self-hosting, so you can obtain a ZIP archive or tarball
containing a snapshot of the <em>latest</em> version directly from
Fossil's own fossil repository. Additionally, source archives of
<em>released</em> versions of
fossil are available from the [/uv/download.html|downloads page].
To obtain a development version of fossil, follow these steps:
<ol>
<li>Point your web browser to [https://fossil-scm.org/]</li>
<li>Click on the [/timeline|Timeline]
link at the top of the page.</li>
<li>Select a version of Fossil you want to download. The latest
version on the trunk branch is usually a good choice. Click on its
link.</li>
<li>Finally, click on one of the
"Zip Archive" or "Tarball" links, according to your preference.
These links will build a ZIP archive or a gzip-compressed tarball of the
complete source code and download it to your computer.</li>
</ol>
<h2>Aside: Is it really safe to use an unreleased development version of
the Fossil source code?</h2>
Yes! Any check-in on the
[/timeline?t=trunk | trunk branch] of the Fossil
[https://fossil-scm.org/ | self-hosting repository]
will work fine. (Dodgy code is always on a branch.) In the unlikely
event that you pick a version with a serious bug, it still won't
clobber your files. Fossil uses several
[./selfcheck.wiki | self-checks] prior to committing any
repository change that prevent loss-of-work due to bugs.
The Fossil [./selfhost.wiki | self-hosting repositories], especially
the one at [https://fossil-scm.org/home], usually run a version
of trunk that is less than a week or two old. Look at the bottom
left-hand corner of this screen (to the right of "This page was
generated in...") to see exactly which version of Fossil is
rendering this page. It is always safe to use whatever version
of the Fossil code you find running on the main Fossil website.
<h2>2.0 Compiling</h2>
<ol>
<li value="5">
Unpack the ZIP or tarball you downloaded then
<b>cd</b> into the directory created.</li>
<li><i>(Optional, Debian-compatible Linux only)</i>
Make sure you have all the necessary tools and libraries at hand by running:
<b>sudo apt install tcl-dev tk libssl-dev zlib1g-dev</b>.
<li><i>(Optional, Unix only)</i>
Run <b>./configure</b> to construct a makefile.
<ol type="a">
<li>
The build system for Fossil on Unix-like systems assumes that the
OpenSSL development and runtime files are available on your system,
because unprotected repositories are trivial to attack otherwise.
Indeed, some public Fossil repositories — including Fossil's own — today
run in an HTTPS-only mode, so that you can't even do an anonymous clone
from them without using the TLS features added to Fossil by OpenSSL. To
weaken that stance could allow a
[https://en.wikipedia.org/wiki/Man-in-the-middle_attack|man in the
middle attack], such as one that substitutes malicious code into your
Fossil repository clone.
You can force the Fossil build system to avoid searching for, building
against, and linking to the OpenSSL library by passing
<b>--with-openssl=none</b> to the <tt>configure</tt> script.
If you do not have the OpenSSL development libraries on your system,
we recommend that you install them, typically via your OS's package
manager. The Fossil build system goes to a lot of effort to seek these
out wherever they may be found, so that is typically all you need to
do.
For more advanced use cases, see the [./ssl.wiki#openssl-bin|OpenSSL
discussion in the "TLS and Fossil" document].
</li>
<li>
To build a statically linked binary, you can <i>try</i> adding
the <b>--static</b> option, but
[https://stackoverflow.com/questions/3430400/linux-static-linking-is-dead
| it may well not work]. If your platform of choice is affected by this,
the simplest workaround we're aware of is to build a Fossil container,
then [./containers.md#static | extract the static executable from it].
</li>
<li>
To enable the native [./th1.md#tclEval | Tcl integration feature] feature,
add the <b>--with-tcl=1</b> and <b>--with-tcl-private-stubs=1</b> options.
</li>
<li>
Other configuration options can be seen by running
<b>./configure --help</b>
</li>
</ol>
<li>Run "<b>make</b>" to build the "fossil" or "fossil.exe" executable.
The details depend on your platform and compiler.</li>
<ol type="a">
<li><i>Unix</i> → the configure-generated Makefile should work on
all Unix and Unix-like systems. Simply type "<b>make</b>".</li>
<li><i>Unix without running "configure"</i> → if you prefer to avoid
running configure, you can also use: <b>make -f Makefile.classic</b>. You may
want to make minor edits to Makefile.classic to configure the build for your
system.</li>
<li><i>MinGW / MinGW-w64</i> → The best-supported path is to build
via the MinGW specific Makefile under a POSIX build of GNU make:
"<b>make -f win/Makefile.mingw</b>".</li>
There is limited support for building under MinGW's native Windows port
of GNU Make instead by defining the <tt>USE_WINDOWS=1</tt> variable, but
it's better to build under MSYS, Cygwin, or WSL on Windows since this
mode doesn't take care of cases such as the "openssl" target, which
depends on <tt>sed</tt>. We've gone as far down this path as is
practical short of breaking cross-compilation under Linux, macOS, and so
forth, as we'd have to do to make everything work under
<tt>cmd.exe</tt>.
Unless you're building under MSYS where commands like "<tt>gcc</tt>"
give MinGW's GCC and not some other version, you will need to make minor
edits to win/Makefile.mingw to configure the cross-compilation
environment. It should suffice to switch to one of the predefined
<tt>PREFIX</tt> values, causing the build to be done using
"<tt>x86_64-w64-mingw32-gcc</tt>" for example, yielding a 64-bit native
Windows binary.
To enable the native [./th1.md#tclEval | Tcl integration feature], use a
command line like the following (all on one line):
<b>make -f win/Makefile.mingw FOSSIL_ENABLE_TCL=1 FOSSIL_ENABLE_TCL_STUBS=1 FOSSIL_ENABLE_TCL_PRIVATE_STUBS=1</b>
Alternatively, running <b>./configure</b> under MSYS should give a
suitable top-level Makefile. However, options passed to configure that are
not applicable on Windows may cause the configuration or compilation to fail
(e.g. fusefs, internal-sqlite, etc).
<li><i>MSVC</i> → Use the MSVC makefile.</li>
<em>NB:</em> Run the following <code>nmake</code> commands from a "x64 Native
Tools Command Prompt"; <code>buildmsvc.bat</code> is able to automatically load
the build tools (x64 by default, pass "x86" as the first argument to use the
x86 tools), so it can be called from a normal command prompt.
First, change to the "win/" subdirectory ("<b>cd win</b>"), then run
"<b>nmake /f Makefile.msc</b>".<br><br>Alternatively, the batch
file "<b>win\buildmsvc.bat</b>" may be used and it will attempt to
detect and use the latest installed version of MSVC.<br><br>To enable
the optional <a href="https://www.openssl.org/">OpenSSL</a> support,
first <a href="https://www.openssl.org/source/">download the official
source code for OpenSSL</a> and extract it to an appropriately named
"<b>openssl</b>" subdirectory within the local
[/tree?ci=trunk&name=compat | compat] directory then make sure that some recent
<a href="http://www.perl.org/">Perl</a> binaries are installed locally,
and finally run one of the following commands:
<pre>
nmake /f Makefile.msc FOSSIL_ENABLE_SSL=1 FOSSIL_BUILD_SSL=1 PERLDIR=C:\full\path\to\Perl\bin
</pre>
<pre>
buildmsvc.bat FOSSIL_ENABLE_SSL=1 FOSSIL_BUILD_SSL=1 PERLDIR=C:\full\path\to\Perl\bin
</pre>
To enable the optional native [./th1.md#tclEval | Tcl integration feature],
run one of the following commands or add the "FOSSIL_ENABLE_TCL=1"
argument to one of the other NMAKE command lines:
<pre>
nmake /f Makefile.msc FOSSIL_ENABLE_TCL=1
</pre>
<pre>
buildmsvc.bat FOSSIL_ENABLE_TCL=1
</pre>
<li><i>Cygwin</i> → The same as other Unix-like systems. It is
recommended to configure using: "<b>configure --disable-internal-sqlite</b>",
making sure you have the "libsqlite3-devel" , "zlib-devel" and
"openssl-devel" packages installed first.</li>
</ol>
</ol>
<h2>3.0 Installing</h2>
<ol>
<li value="9">
The finished binary is named "fossil" (or "fossil.exe" on Windows).
Put this binary in a
directory that is somewhere on your PATH environment variable.
It does not matter where.
</li>
<li>
<b>(Optional:)</b>
To uninstall, just delete the binary.
</li>
</ol>
<h2>4.0 Additional Considerations</h2>
<ul>
<li>
If the makefiles that come with Fossil do not work for
you, or for some other reason you want to know how to build
Fossil manually, then refer to the
[./makefile.wiki | Fossil Build Process] document which describes
in detail what the makefiles do behind the scenes.
</li>
<li>
The fossil executable is self-contained and stand-alone and usually
requires no special libraries or other software to be installed. However,
the "--tk" option to the [/help/diff|diff command] requires that Tcl/Tk
be installed on the local machine. You can get Tcl/Tk from
[http://www.activestate.com/activetcl|ActiveState].
</li>
<li>
To build on older Macs (circa 2002, MacOS 10.2) edit the Makefile
generated by configure to add the following lines:
<pre>
TCC += -DSQLITE_WITHOUT_ZONEMALLOC
TCC += -D_BSD_SOURCE
TCC += -DWITHOUT_ICONV
TCC += -Dsocketlen_t=int
TCC += -DSQLITE_MAX_MMAP_SIZE=0
</pre>
</li>
</ul>
<h2 id="docker" name="oci">5.0 Building a Docker Container</h2>
The information on building Fossil inside an
[https://opencontainers.org/ | OCI container] is now in
[./containers.md | a separate document].
This includes the instructions on using the OCI container as an
expedient intermediary for building a statically-linked Fossil binary on
modern Linux platforms, which otherwise make this difficult.
<h2>6.0 Building on/for Android</h2>
<h3>6.1 Cross-compiling from Linux</h3>
The following instructions for building Fossil for Android via Linux,
without requiring a rooted OS, are adapted from
[forum:/forumpost/e0e9de4a7e | a forum post].
On the development machine, from the fossil source tree:
<pre><code>export CC=$NDK_PATH/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi21-clang
./configure --with-openssl=none
make
</code></pre>
On the Android device, enable the <em>USB debugging</em> option from
Developer menu in Device Options. Connect the device to the development
system with USB. If it's configured and connected properly,
the device should show up in the output of <code>adb devices</code>:
<pre><code>sudo adb devices
</code></pre>
Copy the resulting fossil binary onto the device...
<pre><code>sudo adb push fossil /data/local/tmp
</code></pre>
And run it from an <code>adb</code> shell:
<pre><code>sudo adb shell
> cd /data/local/tmp
# Fossil requires a HOME directory to work with:
> export HOME=$PWD
> export PATH=$PWD:$PATH
> fossil version
This is fossil version 2.11 [e5653a4ceb] 2020-03-26 18:54:02 UTC
</code></pre>
The output might, or might not, include warnings such as:
<pre><code>WARNING: linker: ./fossil: unused DT entry: type 0x6ffffef5 arg 0x1464
WARNING: linker: ./fossil: unused DT entry: type 0x6ffffffe arg 0x1ba8
WARNING: linker: ./fossil: unused DT entry: type 0x6fffffff arg 0x2
</code></pre>
The source of such warnings is not 100% certain.
Some information about these (reportedly harmless) warnings can
be found
[https://stackoverflow.com/a/41900551 | on this StackOverflow post].
<a id='fuzzer'></a>
<h2>7.0 Building for Fuzz Testing</h2>
This feature is primarily intended for fossil's developers and may
change at any time. It is only known to work on Linux systems and has
been seen to work on x86/64 and ARM.
Fossil has builtin support for processing specific features using
<tt>libfuzzer</tt>. The features which can be tested this way are
found in the help text for the [/help?cmd=test-fuzz|test-fuzz
command].
Fuzzing requires:
* Customizing the build of fossil a small bit.
* The clang C compiler.
* libfuzzer. On Ubuntu-derived systems, it can be installed with
<tt>apt install libfuzzer-XYZ</tt>, where XYZ is a version number
(several versions may be available on any given system)
First, modify the top-level <tt>Makefile.in</tt>:
* Extend the <tt>TCCFLAGS</tt> variable with: <tt>-fsanitize=fuzzer
-DFOSSIL_FUZZ</tt> (and see [/finfo/src/fuzz.c | src/fuzz.c] for
more options).
* Rename <tt>APPNAME</tt> from <tt>fossil</tt> to <tt>fossil-fuzz</tt>.
Then rebuild:
<pre></code>$ make clean
$ ./configure CC=/path/to/clang
$ make
</code></pre>
If clang is your default compiler, the <tt>CC</tt> configure option is
not required.
The resulting <tt>fossil-fuzz</tt> binary differs from the standard
one primarily in that it runs the <tt>test-fuzz</tt> command by
default. It needs to be told what to fuzz and needs to be given a
directory of input files to seed the fuzzer with:
<pre></code>$ mkdir cases
# Copy input files into ./cases. e.g. when fuzzing the markdown
# processor, copy any to-be-tested .md files into that directory.
# Then start the fuzzer:
$ ./fossil-fuzz --fuzztype markdown cases
</code></pre>
As it works, it writes its mutated test files into the test-input
directory, each one named in the form of a hash. When it finds a
problem it will produce a stack trace for the offending code, will
output the name of the file which triggered the crash (named
<tt>cases/SOME_HASH</tt>) and may, depending on the nature of the
problem, produce a file named <tt>crash-SOMETHING</tt>. In theory the
crash file can be fed directly back into the fuzzer to reproduce the
problem:
<pre></code>$ ./fossil-fuzz --fuzztype markdown crash-SOMETHING
</code></pre>
But whether or not it will genuinely crash may depend on static
app-level state which might not trigger the crash when running an
individual test.
For a detailed information about the fuzzer's flags and features, see:
* [https://llvm.org/docs/LibFuzzer.html]
* [https://github.com/google/fuzzing/blob/master/tutorial/libFuzzerTutorial.md]
Flags for the fuzzer can be passed directly to fossil,
e.g. <tt>-jobs=4</tt> to start four fuzzer jobs in parallel, but doing
so may cause the fuzzer to <em>strip the --fuzztype flag</em>, leading
to it testing the wrong thing. When passing on fuzzer-specific flags
along with <tt>--fuzztype</tt>, be sure to check your system's process
list to ensure that your <tt>--fuzztype</tt> flag is there.
<a id='wasm'></a>
<h2>8.0 Building WebAssembly Components</h2>
Fossil uses one component built as
[https://developer.mozilla.org/en-US/docs/WebAssembly | WebAssembly]
a.k.a. WASM. Because compiling WASM code requires non-trivial
client-side tooling, the repository includes compiled copies of these
pieces. Most Fossil hackers should never need to concern themselves
with the WASM parts, but this section describes how to for those who
want or need to do so.
<strong>The bits described in this section are necessary when updating
<tt>extsrc/pikchr.c</tt></strong> from the upstream source, or the
fossil binary will use a different version of pikchr than
[/pikchrshow] does (as the latter runs the WASM build of pikchr).
These instructions have only ever been tested on Linux systems. They
"should" work on any Unix-like system supported by Emscripten. The
fossil makefiles for Windows builds <em>do not</em> include any of the
WASM-related components (patches to add that would be welcomed, of
course).
The first step is to configure the tree with support for
[https://emscripten.org/|Emscripten]. This requires that the system
has the Emscripten SDK (a.k.a. emsdk) installed, as documented at:
[https://emscripten.org/docs/getting_started/downloads.html]
For instructions on keeping the SDK up to date, see:
[https://emscripten.org/docs/tools_reference/emsdk.html]
<div class="sidebar">Getting Emscripten up and running is trivial and
painless, at least on Linux systems, but the installer downloads
many hundreds of megabytes of tools and dependencies, all of which
will be installed under the single SDK directory (as opposed to
being installed at the system level). It does, however, require
that python3 be installed at the system level and it can
optionally make use of a system-level cmake for certain tasks
unrelated to how fossil uses the SDK.</div>
After installing the SDK, configure the fossil tree with emsdk
support:
<pre><code>$ ./configure --with-emsdk=/path/to/emsdk \
--and-other-options...
</code></pre>
If the <tt>--with-emsdk</tt> flag is not provided, the configure
script will check for the environment variable <tt>EMSDK</tt>, which
is one of the standard variables the SDK environment uses. If that
variable is found, its value will implicitly be used in place of the
missing <tt>--with-emsdk</tt> flag. Thus, if the <tt>emsdk_env.sh</tt>
script is sourced into the shell before running the configure script,
the SDK will be detected even without the config flag.
The configure script installs some makefile variables which tell the
build where to find the SDK and it generates a script named
<tt>tools/emcc.sh</tt> (from the template file
<tt>[/file/tools/emcc.sh.in|/tools/emcc.sh.in]</tt>), which is a
wrapper around the Emscripten C compiler (<tt>emcc</tt>). The wrapper
script uses the configure-time state to attempt to set up the various
environment variables which are required by <tt>emcc</tt> and will
fail if it cannot do so. Once it's set up the environment, it passes
on all of its arguments to <tt>emcc</tt>.
The WASM-related build parts are set up such that none of them should
ever trigger implicitly (e.g. via dependencies resolution) in a normal
build cycle. They are instead explicitly built as described below.
From the top of the source tree, all WASM-related components can be
built with:
<pre><code>$ make wasm</code></pre>
<div class="sidebar">The file
<tt>[/file/extsrc/pikcher-worker.js|extsrc/pikcher-worker.js]</tt>
is hand-coded and intended to be loaded as a "Worker" in
JavaScript. That file loads the main module and provides an
interface via which a main JavaScript thread can communicate with
pikchr running in a Worker thread. The file
<tt>[/file/src/fossil.page.pikchrshowasm.js|src/fossil.page.pikchrshowasm.js]</tt>
implements the [/pikchrshow] app and demonstrates how
<tt>pikchr-worker.js</tt> is used.</div>
As of this writing, those parts include:
* <tt>extsrc/pikchr.wasm</tt> is a WASM-compiled form of
<tt>extsrc/pikchr.c</tt>.
* <tt>extsrc/pikchr.js</tt> is JS/WASM glue code generated by Emscripten
to give JS code access to the API exported by the WASM file.
When a new version of <tt>extsrc/pikchr.c</tt> is installed, the
files <tt>pikchr.{js,wasm}</tt> will need to be recompiled to account
for that. Running <tt>make wasm</tt> will, if the build is set up for
the emsdk, recompile those:
<pre><code>$ make wasm
./tools/emcc.sh -o extsrc/pikchr.js ...
$ ls -la extsrc/pikchr.{js,wasm}
-rw-rw-r-- 1 stephan stephan 17263 Jun 8 03:59 extsrc/pikchr.js
-rw-rw-r-- 1 stephan stephan 97578 Jun 8 03:59 extsrc/pikchr.wasm
</code></pre>
<div class="sidebar">If that fails with a message along the lines of
“<code>setting `EXPORTED_RUNTIME_METHODS` expects `<class 'list'>` but
got `<class 'str'>`</code>†then the emcc being invoked is too old: emcc
changed the format of list-type arguments at some point. The required
minimum version is unknown, but any SDK version from May 2022 or later
"should" (as of this writing) suffice. Any older version may or may not
work.</div>
After that succeeds, we need to run the normal build so that those
generated files can be compiled in to the fossil binary, accessible
via the [/help?cmd=/builtin|/builtin page]:
<pre><code>$ make</code></pre>
Before checking in those newly-built files, they need to be tested by
running the [/pikchrshow] page. If that page loads, the compilation
process fundamentally worked (a load failure will be made obvious to
the viewer). If it fails to load then the browser's dev tools console
likely provides at least a small hint (and <em>sometimes</em> a useful
hint) about the nature of the problem. Don't check those files in
until [/pikchrshow] runs, though!
Should pikchr's C interface ever change, <tt>pikchr-worker.js</tt>
will need to be updated to accommodate it, but such modification is
typically trivial.
<h3>8.1 Solutions other than Emscripten?</h3>
Emscripten is not the only option for building C as WASM, but it
provides a complete toolchain which eliminates many other steps which
must otherwise be accounted for on a per-project basis. Despite its
convenience, it behooves us to explore other build options for the
sake of portability and avoiding what amounts to vendor lock-in.
For later refererence, here are articles specifically covering
building WASM projects without using Emscripten:

A software system can no more get around it than a physical system can get past *c*, the [speed of light][sol] constant. Fossil is a distributed system, so it can be useful to think about it in terms of the CAP theorem. We won’t discuss the theorem itself or how you reason using its results here. For that, we recommend [this article][tut]. [cap]: https://en.wikipedia.org/wiki/CAP_theorem [sol]: https://en.wikipedia.org/wiki/Speed_of_light [tut]: https://www.ibm.com/cloud/learn/cap-theorem <a id="ap"></a> ## Fossil Is an AP-Mode System As with all common [DVCSes][dvcs], Fossil is an AP-mode system, meaning that your local clone isn’t necessarily consistent with all other clones (C), but the system is always available for use (A) and partition-tolerant (P). This is what allows you to turn off Fossil’s autosync mode, go off-network, and continue working with Fossil, even though only a single node (your local repo clone) is accessible at the time. You may consider that going back online restores “Câ€, because upon sync, you’re now consistent with the repo you cloned from. But, if another user has gone offline in the meantime, and they’ve made commits to their disconnected repo, *you* aren’t consistent with *them.* Besides which, if another user commits to the central repo, that doesn’t push the change down to you automatically: even if all users of a Fossil system are online at the same instant, and they’re all using autosync, Fossil doesn’t guarantee consistency across the network. There’s no getting around the CAP theorem! [dvcs]: https://en.wikipedia.org/wiki/Distributed_version_control <a id="ca"></a> ## CA-Mode Fossil What would it mean to redesign Fossil to be CA-mode? It means we get a system that is always consistent (C) and available (A) as long as there are no partitions (P). That’s basically [CVS] and [Subversion][svn]: you can only continue working with the repository itself as long as your connection to the central repo server functions. It’s rather trivial to talk about single-point-of-failure systems like CVS or Subversion as CA-mode. Another common example used this way is a classical RDBMS, but aren’t we here to talk about distributed systems? What’s a good example of a *distributed* CA-mode system? A better example is [Kafka], which in its default configuration assumes it being run on a corporate LAN in a single data center, so network partitions are exceedingly rare. It therefore sacrifices partition tolerance to get the advantages of CA-mode operation. In its particular application of this mode, a message isn’t “committed†until all running brokers have a copy of it, at which point the message becomes visible to the client(s). In that way, all clients always see the same message store as long as all of the Kafka servers are up and communicating. How would that work in Fossil terms? If there is only one central server and I clone it on my local laptop, then CA mode means I can only commit if the remote Fossil is available, so in that sense, it devolves to the old CVS model. What if there are three clones? Perhaps there is a central server *A*, the clone *B* on my laptop, and the clone *C* on your laptop. Doesn’t CA mode now mean that my commit on *B* doesn’t exist after I commit it to the central repo *A* until you, my coworker, *also* pull down the copy of that commit to your laptop *C*, validating the commit through the network? That’s one way to design the system, but another way would be to scope the system to only talk about proper *servers*, not about the clients. In that model, a CA-mode Fossil alternative might require 2+ servers to be running for proper replication. When I make a commit, if all of the configured servers aren’t online, I can’t commit. This is basically CVS with replication, but without any useful amount of failover. [CVS]: https://en.wikipedia.org/wiki/Concurrent_Versions_System [Kafka]: https://engineering.linkedin.com/kafka/intra-cluster-replication-apache-kafka [svn]: https://en.wikipedia.org/wiki/Apache_Subversion <a id="cp"></a> ## CP-Mode Fossil What if we modify our CA-mode system above with “warm sparesâ€? We can say that commits must go to all of the spares as well as the active servers, but a loss of one active server requires that one warm spare come into active state, and all of the clients learn that the spare is now considered “active.†At this point, you have a CP-mode system, not a CA-mode system, because it’s now partition-tolerant (P) but it becomes unavailable when there aren’t enough active servers or warm spares to promote to active status. CP is your classical [BFT] style distributed consensus system, where the system is available only if the client can contact a *majority* of the servers. This is a formalization of the warm spare concept above: with *N* server nodes, you need at least ⌊*N* / 2⌋ + 1 of them to be online for a commit to succeed. Many distributed database systems run in CP mode because consistency (C) and partition-tolerance (P) is a useful combination. What you lose is always-available (A) operation: with a suitably bad partition, the system goes down for users on the small side of that partition. An optional CP mode for Fossil would be attractive in some ways since in some sense Fossil is a distributed DBMS, but in practical terms, it means Fossil would then not be a [DVCS] in the most useful sense, being that you could work while your client is disconnected from the remote Fossil it cloned from. A fraught question is whether the non-server Fossil clones count as “nodes†in this sense. If they do count, then if there are only two systems, the central server and the clone on my laptop, then it stands to reason from the formula above that I can only commit if the central server is available. In that scheme, a CP-mode Fossil is basically like CVS. But what happens if my company hires a coworker to help me with the project, and this person makes their own clone of the central repo? The equation says I still need 2 nodes to be available for a commit, so if my new coworker goes off-network, that doesn’t affect whether I can make commits. Likewise, if I go off-network, my coworker can make commits to the central server. But what happens if the central server goes down? The equation says we still have 2 nodes, so we should be able to commit, right? Sure, but only if my laptop and communicate directly to my coworker’s laptop! If it can’t, that’s also a network partition, so *N=1* on both sides in that case. The implication is that for a true CP-mode Fossil, we’d need some kind of peer-to-peer networking layer so that our laptops can accept commits from the other, so that when the central server comes online, one of us can send the results up to it to get it caught up. But doesn’t that then mean there is no security? How does [Fossil’s RBAC system][caps] work if peer-to-peer commits are allowed? You can instead reconceptualize the system as “node†meaning only server nodes, so that client-only systems don’t count. This allows you to have an RBAC system again. With just one central server, ⌊1/2⌋+1=1, so you get CVS-like behavior: if the server’s up, you can commit. If you set up 2 servers for redundancy, both must be up for commits to be allowed, since otherwise you could end up with half the commits going to the server on one side of a network partition, half going to the other, and no way to arbitrate among the two once the partition is lifted. (Today’s AP-mode Fossil has this capability, but the necessary cost is “Câ€, consistency! Once again, you can’t get around the CAP theorem.) 3 servers is more sensible: any client that can see at least 2 of them can commit. Will there ever be a CP-mode Fossil? This author doubts it, but as I’ve shown, it would be useful in contexts where you’d rather have a guarantee of consistency than availability.

# Differences Between Setup and Admin Users
This document explains the distinction between [Setup users][caps] and
[Admin users][capa]. For other information about use types, see:
* [Administering User Capabilities](./)
* [How Moderation Works](../forum.wiki#moderation)
* [Users vs Subscribers](../alerts.md#uvs)
* [Defense Against Spiders](../antibot.wiki)
## <a id="philosophy"></a>Philosophical Core
The Setup user "owns" the Fossil repository and may delegate a subset of
that power to one or more Admin users.
The Setup user can grant Admin capability and take it away, but Admin
users cannot grant themselves Setup capability, either directly via the
Admin → Users UI page or via any indirect means. (If you discover
indirect means to elevate Admin privilege to Setup, it's a bug, so
please [report it][forum]!)
It is common for the Setup user to have administrative control over the
host system running the Fossil repository, whereas it makes no sense for
Admin users to have that ability. If an Admin-only user had `root`
access on a Linux box running the Fossil instance they are an Admin on,
they could elevate their capability to Setup in several ways. (The
`fossil user` command, the `fossil sql` command, editing the repository
DB file directly, etc.) Therefore, if you wish to grant someone
Setup-like capability on a Fossil repository but you're unwilling to
give them a login on the host system, you probably want to grant
them Admin capability instead.
Admin power is delegated from Setup. When a Setup user grants Admin
capability, it is an expression of trust in that user's judgement.
Admin-only users must not fight against the policies of the Setup user.
Such a rift would be just cause for the Setup user to strip the Admin
user's capabilities. This may then create a fork in the project’s
development effort as the ex-Admin takes their clone and stands it up
elsewhere, so they may become that fork’s Setup user.
A useful rule of thumb here is that Admin users should only change
things that the Setup user has not changed from the stock configuration.
In this way, an Admin-only user can avoid overriding the Setup user's
choices.
You can also look at the role of Admin from the other direction, up
through the [user power hierarchy][ucap] rather than down from Setup. An
Admin user is usually a “super-developer†role, given full control over
the repository’s managed content: versioned artifacts in [the hash tree][bc],
[unversioned content][uv], forum posts, wiki articles,
tickets, etc.
We’ll explore these distinctions in the rest of this document.
[bc]: ../blockchain.md
[ucap]: ./index.md#ucap
[uv]: ../unvers.wiki
## <a id="binary"></a>No Granularity
Fossil doesn’t make any distinction between these two user types beyond
this binary choice: Setup or Admin.
A few features of Fossil are broken down so that only part of the
feature is accessible to Admin, with the rest left only to Setup users,
but for the most part each feature affected by this distinction is
either Admin + Setup or Setup-only.
We could add more capability letters to break down individual
sub-features, but we’d run out of ASCII alphanumerics pretty quickly,
and we might even run out of ASCII punctuation and symbols. Then would
we need to shift to Unicode?
Consider the Admin → Settings page, which is currently restricted to
Setup users only: you might imagine breaking this up into several
subsets so that some settings can be changed by Admin users. Is that a
good idea? Maybe, but it should be done only after due consideration. It
would definitely be wrong to assign a user capability bit to *each*
setting on that page.
Now consider the opposite sort of case, Admin → Skins. Fossil grants
Admin users full access to this page so that the Admins can maintain and
extend the skin as the repository evolves, not so Admins can switch the
entire skin to another without consulting with the Setup user first. How
would Fossil decide, using user capabilities only, which skin changes
the Admin user is allowed to do, and which must be left to Setup? Do we
assign a separate capability letter to each step in `/setup_skin`? Do we
assign one more each to the five sections of a skin? (Header, Footer,
CSS, JavaScript, and Details.) It quickly becomes unmanageable.
## <a id="capgroups"></a>Capability Groups
We can break up the set of powers the Admin user capability grants into
several groups, then defend each group as a coherent whole.
### <a id="security"></a>Security
While establishing the Fossil repository's security policy is a task for
the Setup user, *maintaining* that policy is something that Fossil
allows a Setup user to delegate to trustworthy users via the Admin user
capability:
* **Manage users**: The only thing an Admin-only user cannot do on the
Admin → Users page is grant Setup capability, either to themselves
or to other users. The intent is that Admin users be able to take
some of the load of routine user management tasks off the shoulders
of the Setup user: delete accounts created by spammers, fix email
alert subscriptions, reset passwords, etc.
* **Security audit**: The Admin → Security-Audit page runs several
tests on the Fossil repository's configuration, then reports
potential problems it found and offers canned solutions. Those
canned solutions do not do anything that an Admin-user could not do
via other means, so this page offers the Admin-only user no more
power than they otherwise had. For example, this page's "Take it
Private" feature can also be done manually via Admin → Users. This
page is a convenience, not a grant of new power to the Admin-only
user.
* **Logging**:<a id="log"></a> Admin-only users get to see the various
Fossil logs in case they need to use them to understand a problem
they're empowered to solve. An obvious example is a spam attack: the
Admin might want to find the user's last-used IP, see if they cloned
the repository, see if they attempted to brute-force an existing
login before self-registering, etc.
Some security-conscious people might be bothered by the fact that
Admin-only users have these abilities. Think of a large IT organization:
if the CIO hires a [tiger team][tt] to test the company's internal IT
defenses, the line grunts fix the reported problems, not the CIO.
### <a id="administrivia"></a>Administrivia
It is perfectly fine for a Fossil repository to only have Setup users,
no Admin users. The smaller the repository, the more likely the
repository has no Admin-only users. If the Setup user neither needs nor
wants to grant Admin power to others, there is no requirement in Fossil
to do so. [Setup capability is a pure superset of Admin capability.][sia]
As the number of users on a Fossil repository grows, the value in
delegating administrivia also grows, because the Setup user typically
has other time sinks they consider more important.
Admin users can take over the following routine tasks on behalf of the
Setup user:
* **Shunning**: After user management, this is one of the greatest
powers of an Admin-only user. Fossil grants access to the Admin →
Shunned page to Admin users rather than reserve it to Setup users
because one of the primary purposes of [the Fossil shunning
system][shun] is to clean up after a spammer, and that's
exactly the sort of administrivia we wish to delegate to Admin users.
Coupled with the Rebuild button on the same page, an Admin user has
the power to delete the repository's entire
[hash tree][bc]! This makes this feature a pretty good
razor in deciding whether to grant someone Admin capability: do you
trust that user to shun Fossil artifacts responsibly?
Realize that shunning is cooperative in Fossil. As long as there are
surviving repository clones, an Admin-only user who deletes the
whole hash tree has merely caused a nuisance. An Admin-only user
cannot permanently destroy the repository unless the Setup user has
been so silly as to have no up-to-date clones.
* **Moderation**: According to [the user power hierarchy][ucap],
Admins are greater than Moderators, so control over
what Moderators can do clearly belongs to both Admins and to the
Setup user(s).
* **Status**: Although the Fossil `/stat` page is visible to every
user with Read capability, there are several additional things this
page gives access to when a user also has the Admin capability:
* <p>[Email alerts][ale] and [backoffice](../backoffice.md)
status. Admin-only users cannot modify the email alerts setup,
but they can see some details about its configuration and
current status.</p>
* <p>The `/urllist` page, which is a read-only page showing the
ways the repository can be accessed and how it has been accessed

### <a id="cosmetics"></a>Cosmetics
While the Setup user is responsible for setting up the initial "look" of
a Fossil repository, the Setup user entrusts Admin users with
*maintaining* that look. An Admin-only user therefore has the following
special abilities:
* Modify the repository skin
* Create and modify URL aliases
* Manage the "ad units" feature, if enabled.
* Adjust the `/timeline` display preferences.
* Change the "logo" element displayed by some skins.
These capabilities allow an Admin-only user to affect the branding and
possibly even the back-end finances of a project. This is why we began
this document with a philosophical discussion: if you cannot entrust a
user with these powers, you should not grant that user Admin capability.
## <a id="clones"></a>Clones and Backups
Fossil is a *distributed* version control system, which has direct
effects on the “Setup user†concept in the face of clones. When you
clone a repository, your local user becomes a Setup user on the local
clone even if you are not one on the remote repository. This may be
surprising to you, but it should also be sensible once you realize that
your operating system will generally give you full control over the
local repository file. What use trying to apply remote restrictions on
the local file, then?
The distinctions above therefore are intransitive: they apply only
within a single repository instance.
Fossil behaves differently when you do a clone as a user with Setup
capability on the remote repository, which primarily has effects on the
fidelity of clone-as-backup, which we cover [elsewhere](../backup.md).
We strongly encourage you to read that document if you expect to use a
clone as a complete replacement for the remote repository.
## <a id="apsu"></a>The All-Powerful Setup User
Setup users get [every user capability](./ref.html) of Fossil except for
[two exceptionally dangerous capabilities](#dcap), which they can later
grant to themselves or to others.
In addition, Setup users can use every feature of the Fossil UI. If Fossil can do a
thing, a Setup user on that repo can make Fossil do it.
Setup users can do many things that Admin users cannot. They may not
only use all of the Admin UI features, they may also:
* See record IDs (RIDs) on screens that show them
* See the MIME type of attachments on [`/ainfo` pages](/help?cmd=/ainfo)
* See a remote repo’s HTTP [cache status](/help?cmd=/cachestat)
and [pull cache entries](/help?cmd=/cacheget)
* Edit a Setup user’s account!
The “Admin†feature of Fossil UI is so-named because Admin users can use
about half of its functions, but only Setup can use these pages:
* **Access**: This page falls under the [Security](#security)
category above, but like Configuration, it's generally something set
up once and never touched, so only Setup users should change it.
* **Configuration**: This page nominally falls
under [Cosmetics](#cosmetics) above, but it's such a core part of the Fossil
configuration — something every Setup user is expected to fully
specify on initial repository setup — that we have trouble
justifying any case where an Admin-only user would have good cause
to modify any of it. This page is generally set up once and then
never touched again.
* **Email-Server**: This is an experimental SMTP server feature which
is currently unused in Fossil. Should we get it working, it will
likely remain Setup-only, since it will likely be used as a
replacement for the platform’s default SMTP server, a powerful
position for a piece of software to take.
* **Login-Group**: [Login groups][lg] allow one Fossil repository to
delegate user access to another. Since an Admin-only user on one
repo might not have such access to another repo on the same host
system, this must be a Setup-only task.
* **Notification**: This is the main UI for setting up integration
with a platform’s SMTP service, for use in sending out [email
notifications][ale]. Because this screen can set commands to execute
on the host, and because finishing the configuration requires a
login on the Fossil host system, it is not appropriate to give Admin
users access to it.
* **Settings**: The [repository settings][rs] available via Admin →
Settings have too wide a range of power to allow modification by
Admin-only users:
* <p><b>Harmless</b>: Admin-only users on a repository may well
have checkin rights on the repository, so the fact that
versionable settings like `crlf-glob` can also be set at the
repository level seems like a thing we might want to allow
Admin-only users the ability to change. Since Fossil currently
has no way to allow only some settings to be changed by
Admin-only users and some not, we can't just show these harmless
settings to Admin-only users.</p>
* <p><b>Low-Risk</b>: The <tt>admin-log</tt> setting controls
whether the Fossil admin log is generated. Since we've <a
href="#log">already decided</a> that Admin-only users can see
this log, it seems fine that the Admin users can choose whether
this log gets generated in the first place.</p>
<p>There's a small risk that a rogue Admin user could disable
the log before doing something evil that the log would capture,
so ideally, we'd want to restrict changing this setting from 1
to 0 to Setup only while allowing Admin-only users to change it
from 0 to 1. Fossil doesn't currently allow that.</p>
* <p><b>Risky</b>: The <tt>https-login</tt> setting falls under
the "Security" section above, but it should probably never be
adjusted by Admin-only users. Sites that want it on will never
want it to be disabled without a very good reason.</p>
<p>There is also an inverse risk: if the site has a front-end
HTTPS proxy that uses HTTP to communicate over localhost to
Fossil, enabling this setting will create an infinite redirect
loop! (Ask me how I know.)</p>
* <p><b>Dangerous</b>: The <tt>email-send-command</tt> setting
could allow a rogue Admin to run arbitrary commands on the host
system, unless it's prevented via some kind of host-specific
restriction. (chroot, jails, SELinux, VMs, etc.) Since it makes
no sense to trust Admin-only users with <tt>root</tt> level
access on the host system, we almost certainly don't want to
allow them to change such settings.</p>
* **SQL**: The Admin → SQL feature allows the Setup user to enter raw
SQL queries against the Fossil repository via Fossil UI. This not
only allows arbitrary ability to modify the repository hash tree
and its backing data tables, it can probably also be used to damage
the host such as via `PRAGMA temp_store = FILE`.
* **Tickets**: This section allows input of arbitrary TH1 code that
runs on the server, affecting the way the Fossil ticketing system
works. The justification in the **TH1** section below therefore
applies.
* **TH1**: The [TH1 language][th1] is quite restricted relative to the
Tcl language it descends from, so this author does not believe there
is a way to damage the Fossil repository or its host via the Admin →
TH1 feature, which allows execution of arbitrary TH1 code within the
repository's execution context. Nevertheless, interpreters are a
well-known source of security problems, so it seems best to restrict
this feature to Setup-only users as long as we lack a good reason
for Admin-only users to have access to it.
* **Transfers**: This is for setting up TH1 hooks on various actions,
so the justification in the **TH1** section above applies.
* **Wiki**: These are mainly cosmetic and usability settings. We might
open this up to Admin users in the future.
Just remember, [user caps affect Fossil’s web interfaces only][webo]. A
user is a Setup user by default on their local clone of a repo, and
Fossil’s ability to protect itself against malicious (or even simply
incorrect) pushes is limited. Someone with clone and push capability on
your repo could clone it, modify their local repo, and then push the
changes back to your repo. Be careful who you give that combination of
capabilities to!
When you run [`fossil ui`][fui], you are the Setup user on that repo
through that UI instance, regardless of the capability set defined in
the repo’s user table. This is true even if you cloned a remote repo
where you do not have Setup caps. This is why `ui` always binds to
`localhost` without needing the `--localhost` flag: in this mode, anyone
who can connect to that repo’s web UI has full power over that repo.
## <a id="dcap"></a>Dangerous Capabilities Initially Denied to Everyone
There are two capabilities that Fossil doesn’t grant by default to Setup
or Admin users automatically. They are exceptionally dangerous, so
Fossil makes these users grant themselves (or others) these capabilities
deliberately, hopefully after careful consideration.
### <a id="y"></a>Write Unversioned
Fossil currently doesn’t distinguish the sub-operations of
[`fossil uv`](/help?cmd=uv); they’re all covered by [**WrUnver**][capy]
(“yâ€) capability. Since some of these operations are unconditionally
destructive due to the nature of unversioned content, and since this
goes against Fossil’s philosophy of immutable history, nobody gets cap
“y†on a Fossil repo by default, not even the Setup or Admin users. A
Setup or Admin user must grant cap “y†to someone — not necessarily
themselves! — before modifications to remote
unversioned content are possible.
Operations on unversioned content made without this capability affect
your local clone only. In this way, your local unversioned file table
can have different content from that in its parent repo. This state of
affairs will continue until your user either gets cap “y†and syncs that
content with its parent or you say `fossil uv revert` to make your local
unversioned content table match that of its parent repo.
### <a id="x"></a>Private Branch Push
For private branches to remain private, they must never be accidentally
pushed to a public repository. It can be [difficult to impossible][shun]
to recover from such a mistake, so nobody gets [**Private**][capx] (“xâ€)
capability on a Fossil repo by default, not even Admin or Setup users.
There are two common uses for private branches.
One use is part of a local social contract allowing individual
developers to work on some things in private until they’re ready to push
them up to the parent repository. This goes against [a core tenet][fdp]
of Fossil’s design philosophy, but Fossil allows it, so some development
organizations do this. If yours is one of these, you might give cap “xâ€
to the “developer†category.
The other use is in development organizations that follow the Fossil
philosophy, where you do not work in private unless you absolutely must.
You may have a public-facing project — let’s call it “SQLite†for the
sake of argument — but then someone comes along and commissions a custom
modification to your project which they wish to keep proprietary. You
do your work on a private branch, which you absolutely must never push
to the public repo, because that would be illegal. (Breach of contract,
copyright violation on a work-for-hire agreement, etc.) If you are using
Fossil in this way, we recommend that you give “x†capability to a
special developer account only, if at all, to minimize the chance of an
accidental push.

# Implementation Details of User Capabilities
## <a id="choices"></a>Capability Letter Choices
We [assigned][ref] user capability characters using only lowercase ASCII
letters at first, so those are the most important within Fossil: they
control the functions most core to Fossil’s operation. Once we used up
most of the lowercase letters, we started using uppercase, and then
during the development of the [forum feature][for] we assigned most of
the decimal numerals. All of the lowercase ASCII letters are now
assigned. Eventually, we might have to start using ASCII
punctuation and symbols. We expect to run out of reasons to define new caps before
we’re forced to switch to Unicode, though the possibilities for [mnemonic][mn]
assignments with emoji are intriguing. <span style="vertical-align:
bottom">😉</span>
The existing caps are usually mnemonic, especially among the
earliest and therefore most central assignments, made when we still had
lots of letters to choose from. There is still hope for good future
mnemonic assignments among the uppercase letters, which are mostly still
unused.
## <a id="bitfield"></a>Why Not Bitfields?
Some may question the use of ASCII character strings for [capability
sets][ucap] instead of bitfields, which are more efficient, both in
terms of storage and processing time.
Fossil handles these character strings in one of two ways. For most HTTP
hits, Fossil [expands][sexp] the string into a [`struct` full of
flags][sff] so that later code can just do simple Boolean tests. In a
minority of cases, where Fossil only needs to check for the presence of
a single flag, it just does a [`strchr()` call][sc] on the string
instead.
Both methods are slower than bit testing in a bitfield, but keep the
execution context in mind: at the front end of an HTTP request handler,
where the nanosecond differences in such implementation details are
completely swamped by the millisecond scale ping time of that repo’s
network connection, followed by the required I/O to satisfy the request.
Either method is plenty fast in that context.
In exchange for this immeasurable cost per hit, we get human-readable
capability sets.
## <a id="filter"></a>Why Doesn’t Fossil Filter “Bad†Artifacts on Sync?
Fossil is more trusting about the content it receives from a remote
clone during sync than you might expect. Common manifestations of this
design choice are:
1. A user may be able to impersonate other users. This can be
[accidental](./index.md#defuser) as well as purposeful.
2. If your local system clock is out-of-sync with absolute time,
artifacts committed to that repo will appear with the “wrong†time
when sync’d. If the time sync error is big enough, it can make
check-ins appear to go back in time and other bad effects.
3. You can purposely overwrite good timestamps with bad ones and push
those changes up to the remote with no interference, even though
Fossil tries to make that a Setup-only operation.
All of this falls out of two of Fossil’s design choices: sync is
all-or-nothing, and [the Fossil hash tree][bc] is immutable. Fossil
would have to violate one or both of these principles to filter such
problems out of incoming syncs.
We have considered auto-[shunning][shun] “bad†content on sync, but this
is [difficult][asd] due to [the design of the sync protocol][dsp]. This
is not an impossible set of circumstances, but implementing a robust
filter on this input path would be roughly as difficult as writing a
basic [inter-frame video codec][ifvc]: do-able, but still a lot of
work. Patches to do this will be thoughtfully considered.
We can’t simply change content as it arrives. Such manipulations would
change the artifact manifests, which would change the hashes, which
would require rewriting all parts of the block chain from that point out
to the tips of those branches. The local Fossil repo must then go
through the same process as the remote one on subsequent syncs in order
to build up a sync sequence that the remote can understand. Even if
you’re willing to accept all of that, this would break all references to
the old artifact IDs in forum posts, wiki articles, check-in comments,
tickets, etc.
The bottom line here is that [**Clone**](./ref.html#g) and
[**Write**](./ref.html#i) are a potent combination of user capabilities.
Be careful who you give that pair to!

# Administering User Capabilities (a.k.a. Permissions)
Fossil includes a powerful [role-based access control system][rbac]
which affects which users have which capabilities(^Some parts of the
Fossil code call these “permissions†instead, but since there is [a
clear and present risk of confusion](#webonly) with operating system
level file permissions in this context, we avoid using that term for
Fossil’s RBAC capability flags in these pages.) within a given
[served][svr] Fossil repository. We call this the “caps†system for
short.
Fossil stores a user’s caps as an unordered string of ASCII characters,
one capability per, [currently](./impl.md#choices) limited to
[alphanumerics][an]. Caps are case-sensitive: “**A**†and “**a**†are
different user capabilities.
This is a complex topic, so some sub-topics have their own documents:
1. [Login Groups][lg]
2. [Implementation Details](./impl.md)
3. [User Capability Reference](./ref.html)
[an]: https://en.wikipedia.org/wiki/Alphanumeric
[avs]: ./admin-v-setup.md
[lg]: ./login-groups.md
[rbac]: https://en.wikipedia.org/wiki/Role-based_access_control
## <a id="ucat"></a>User Categories
Before we explain individual user capabilities and their proper
administration, we want to talk about an oft-overlooked and
misunderstood feature of Fossil: user categories.
Fossil defines four user categories. Two of these apply based on the
user’s login status: **nobody** and **anonymous**. The other two act
like Unix or LDAP user groups: **reader** and **developer**. Because we
use the word “group†for [another purpose][lg] in Fossil, we will
avoid using it that way again in this document. The correct term in
Fossil is “category.â€
Fossil user categories give you a way to define capability sets for four
hard-coded situations within the Fossil C source code. Logically
speaking:
> *(developer* ∨ *reader)* ≥ *anonymous* ≥ *nobody*
When a user visits a [served Fossil repository][svr] via its web UI,
they initially get the capabilities of the “nobody†user category. This
category would be better named “everybody†because it applies whether
you’re logged in or not.
When a user logs in as “anonymous†via [`/login`](/help?name=/login) they
get all of the “nobody†category’s caps plus those assigned to the
“anonymous†user category. It would be better named “user†because it
affects all logged-in users, not just those logged in via Fossil’s
anonymous user feature.
When a user with either the “reader†([**u**][u]) or “developerâ€
([**v**][v]) capability letter logs in, they get their [individual user
caps](#ucap) plus those assigned to this special user category. They
also get those assigned to the “anonymous†and “nobody†categories.
Because “developer†users do not automatically inherit “reader†caps,
it is standard practice to give both letters to your “developer†users:
**uv**. You could instead just assign cap **u** to the “developerâ€
category.
Fossil shows how these capabilities apply hierarchically in the user
editing screen (Admin → Users → name) with the `[N]` `[A]` `[D]` `[R]`
tags next to each capability check box. If a user gets a capability from
one of the user categories already assigned to it, there is no value in
redundantly assigning that same cap to the user explicitly. For example,
with the default **ei** cap set for the “developer†category, the cap
set **ve** is redundant because **v** grants **ei**, which includes
**e**.
We suggest that you lean heavily on these fixed user categories when
setting up new users. Ideally, your users will group neatly into one of
the predefined categories, but if not, you might be able to shoehorn
them into our fixed scheme. For example, the administrator of a
wiki-only Fossil repo for non-developers could treat the “developerâ€
user category as if it were called “author,†and a forum-only repo could
treat the same category as if it were called “member.â€
There is currently no way to define custom user categories.
[svr]: ../server/
## <a id="ucap"></a>Individual User Capabilities
When one or more users need to be different from the basic capabilities
defined in user categories, you can assign caps to individual users. You
may want to have the [cap reference][ref] open when doing such work.
It is useful at this time to expand on the logical
expression [above](#cat), which covered only the four fixed user categories.
When we bring the individual user capabilities into it, the complete
expression of the way Fossil implements user power becomes:
> *setup* ≥ *admin* ≥ *moderator* ≥ *(developer* ∨ *reader)* ≥ *[subscriber]* ≥ *anonymous* ≥ *nobody*
The two additions at the top are clear: [setup is all-powerful][apsu],
and since admin users have [all capabilities][ref] except for Setup
capability, they are [subordinate only to the setup user(s)][avsp].
The moderator insertion could go anywhere from where it’s shown now down
to above the “anonymous†level, depending on what other caps you give to
your moderators. Also, there is not just one type of moderator: Fossil
has [wiki][l], [ticket][q], and [forum][5] moderators, each
independent of the others. Usually your moderators are fairly
high-status users, with developer capabilities or higher, but Fossil
does allow the creation of low-status moderators.
The placement of “subscriber†in that hierarchy is for the
sort of subscriber who has registered an account on the repository
purely to [receive email alerts and announcements][7]. Users with
additional caps can also be subscribers, but not all users *are* in fact
subscribers, which is why we show it in square brackets. (See [Users vs
Subscribers](../alerts.md#uvs).)

## <a id="new"></a>New Repository Defaults
Fossil creates one user account in new repos, which is named after your
OS user name [by default](#defuser).
Fossil gives the initial repository user the [all-powerful Setup
capability][apsu].
Users who visit a [served repository][svr] without logging in get the
“nobody†user category’s caps which default to
**[g][g][j][j][o][o][r][r][z][z]**: clone the repo, read the wiki,
check-out files via the web UI, view tickets, and pull version archives.
This default is suited to random passers-by on a typical FOSS project’s
public web site and its code repository.
Users who [prove they are not a bot][bot] by logging in — even if only
as “anonymous†— get the “nobody†capability set plus
**[h][h][m][m][n][n][c][c]**: see internal hyperlinks, append to
existing wiki articles, file new tickets, and comment on existing
tickets. We chose these additional capabilities as those we don’t want
bots to have, but which a typical small FOSS project would be happy to
give anonymous humans visiting the project site.
The “reader†user category is typically assigned to users who want to be
identified within the repository but who primarily have a passive role
in the project. The default capability set on a Fossil repo adds
**[k][k][p][p][t][t][w][w]** caps to those granted by “nobody†and
“anonymousâ€. This category is not well-named, because the default caps
are all about modifying repository content: edit existing wiki pages,
change one’s own password, create new ticket report formats, and modify
existing tickets. This category would be better named “participantâ€.
Those in the “developer†category get the “nobody†and “anonymous†cap
sets plus **[e][e][i][i]**: view
sensitive user material and check in changes.
[bot]: ../antibot.wiki
## <a id="pvt"></a>Consequences of Taking a Repository Private
When you click Admin → Security-Audit → “Take it private,†one of the
things it does is set the user capabilities for the “nobody†and
“anonymous†user categories to blank, so that users who haven’t logged
in can’t even see your project’s home page, and the option to log in as
“anonymous†isn’t even offered. Until you log in with a user name, all
you see is the repository’s skin and those few UI elements that work
without any user capability checks at all, such as the “Login†link.
Beware: Fossil does not reassign the capabilities these users had to
other users or to the “reader†or “developer†user category! All users
except those with Setup capability will lose all capabilities they
inherited from “nobody†and “anonymous†categories. Setup is the [lone
exception][apsu].
If you will have non-Setup users in your private repo, you should parcel
out some subset of the capability set the “nobody†and “anonymousâ€
categories had to other categories or to individual users first.
## <a id="read-v-clone"></a>Reading vs. Cloning
Fossil has two capabilities that are often confused:
[**Read**](./ref.html#o) and [**Clone**](./ref.html#g).
The **Read** capability has nothing to do with reading data from a local
repository, because [caps affect Fossil’s web interfaces
only](#webonly). Once you’ve cloned a remote repository to your local
machine, you can do any reading you want on that repository irrespective
of whether your local user within that repo has <b>Read</b> capability.
The repo clone is completely under your user’s power at that point,
affected only by OS file permissions and such. If you need to prevent
that, you want to deny **Clone** capability instead.
Withholding the **Read** capability has a different effect: it
prevents a web client from viewing [embedded documentation][edoc],
using [the file browser](/help?name=/dir),
exploring the [history](/help?name=/timeline) of check-ins,
and pulling file content via the [`/artifact`](/help?name=/artifact),
[`/file`](/help?name=/file), and [`/raw`](/help?name=/raw) URLs.
It is common to withhold **Read** capability from low-status visitors
on private or semi-private repos to prevent them from pulling individual
elements of the repo over the web one at a time, as someone may do when
denied the bulk **Clone** capability.
[edoc]: ../embeddeddoc.wiki
## <a id="defuser"></a>Default User Name
By default, Fossil assumes your OS user account name is the same as the
one you use in any Fossil repository. It is the [default for a new
repository](#new), though you can override this with [the `--admin-user`
option][auo]. Fossil has other ways of overriding this in other contexts
such as the `name@` syntax in clone URLs.
It’s simplest to stick with the default; a mismatch can cause problems.
For example, if you clone someone else’s repo anonymously, turn off
autosync, and make check-ins to that repository, they will be assigned
to your OS user name by default. If you later get a login on the remote
repository under a different name and sync your repo with it, your
earlier “private†check-ins will get synced to the remote under your OS
user name!
When such problems occur, you can amend the check-in to hide the
incorrect name from Fossil reports, but the original values remain in
the repository [forever][shun]. It is [difficult enough][fos] to fix
such problems automatically during sync that we are unlikely to ever do
so.
[auo]: /help?name=new
[fos]: ./impl.md#filter
[shun]: ../shunning.wiki
## <a id="utclone"></a>Cloning the User Table
When cloning over HTTP, the initial user table in the local clone is set
to its “[new state:](#new)†only one user with Setup capability, named
after either your OS user account, per the default above, or after the
user given in the clone URL.
There is one exception: if you clone as a named Setup user, you get a
complete copy of the user information. This restriction keeps the user
table private except for the only user allowed to make absolutely
complete clones of a remote repo, such as for failover or backup
purposes. Every other user’s clone is missing this and a few other
items, either for information security or PII privacy reasons.
When cloning with file system paths, `file://` URLs, or over SSH, you
get a complete clone, including the parent repo’s complete user table.
All of the above applies to [login groups][lg] as well.
## <a id="webonly"></a>Caps Affect Web Interfaces Only
Fossil’s user capability system only affects accesses over `http[s]://`
URLs. This includes clone, sync/push/pull, the [UI pages][wp], and [the
JSON API][japi]. For everything else, the user caps aren’t consulted at
all.
The only checks made when working directly with a local repository are
the operating system’s file system permissions. This should strike you
as sensible, since if you have read access to the repository file, you
can do anything you want to that repo DB including giving your user’s
record the [**Setup**][s] capability, after which Fossil’s user
capability system is effectively bypassed. (Or, create another Setup
user, with the same end effect.) If you’re objecting that you need
*write* access to the DB file to achieve this, realize that you can copy
a read-only file to another location, giving yourself write access to
it.
This is why the `fossil ui` command
gives you Setup permissions within Fossil UI: it can’t usefully prevent
you from doing anything through the UI since only the local file system
permissions actually matter, and you can’t start `fossil ui` without
having at least read access to that file.
What may be more surprising to you is that this is also true when
working on a *clone* done over a local file path, except that there are
then two sets of file system permission checks: once to modify the
working check-out’s repo clone DB file, then again on [sync][sync] with
the parent DB file. The Fossil capability checks are effectively
defeated because your user has [**Setup**][s] capability on both sides
of the sync. Be aware that those file checks do still matter, however:
Fossil requires write access to a repo DB while cloning from it, so you
can’t clone from a read-only repo DB file over a local file path.
Even more surprising to you may be the fact that user caps do not affect
cloning and syncing over SSH! (Not unless you go [out of your way][sshfc]
to patch around it, at any rate.) When you make a change to such a
repository, the stock Fossil behavior is that the change first goes to the
local repo clone where file system
permissions are all that matter, but then upon sync, the situation is
effectively the same as when the parent repo is on the local file
system. The reason behind this is that if you can log into the remote
system over SSH and that user has the necessary file system permissions
on that remote repo DB file to allow clone and sync operations, then
we’re back in the same situation as with local files: there’s no point
trying to enforce the Fossil user capabilities when you can just modify
the remote DB directly, so the operation proceeds unimpeded by any user
capability settings on the remote repo.
Where this gets confusing is that *all* Fossil syncs are done over the
HTTP protocol, including those done over `file://` and `ssh://` URLs,
not just those done over `http[s]://` URLs:
* For `ssh://` URLs, Fossil pipes the HTTP conversation through a
local SSH client to a remote instance of Fossil running the
[`test-http`](/help?name=test-http) command to receive the tunneled
HTTP connection. [This interface is intentionally permissionless][sxycap].
* For `file://` URLs — as opposed to plain local file paths —
the “sending†Fossil instance writes its side of
the HTTP conversation out to a temporary file in the same directory
as the local repo clone and then calls itself on the “receivingâ€
repository to read that same HTTP transcript file back in to apply
those changes to that repository. Presumably Fossil does this
instead of using a pipe to ease portability to Windows.
Despite use of HTTP for these URL types, the fact remains that
checks for capabilities like [**Read**][o] and [**Write**][i] within the
HTTP conversation between two Fossil instances only have a useful effect
when done over an `http[s]://` URL.

## <a id="pubpg"></a>Public Pages
In Admin → Access, there is an option for giving a list of [globs][glob]
to name URLs which get treated as if the visitor had [the default cap
set](#defcap). For example, you could take the [**Read**][o] capability
away from the “nobody†user category, who has it by default, to prevent
users without logins from pulling down your repository contents one
artifact at a time, yet give those users the ability to read the project
documentation by setting the glob to match your [embedded
documentation][edoc]’s URL root.
## <a id="defcap"></a>Default User Capability Set
In Admin → Access, you can define a default user capability set, which
is used as:
1. the default caps for users newly created by an Admin or Setup user
2. the default caps for self-registered users, an option in that same UI
3. the effective caps for URIs considered [public pages](#pubpg)
This defaults to [**Reader**][u].

# Login Groups
The Admin → Login-Groups UI feature and its corresponding [`login-group`
command][lg] solve a common problem with Fossil: you’ve created multiple
repositories that some subset of users need access to, and you
don’t want to redundantly administer the user credentials for each
repository.
## Restrictions
This feature ties changes to the “`user`†table in one repo to that in
one or more other repos, keyed by the user’s name. The interactions are
non-obvious because although the goal is for the end result to “just
work,†there are practical security and administration matters that
complicate things:
1. Login group handling only works between joined repositories for the
subset of users with the same name.
1. If you’re logged in on one repo in a group, any other repo in that
group that has a matching user record will accept your valid login.
1. When you set up a login group between two repos, the user tables
aren’t merged, so even though you may have users that appear in
both, they will retain their initial passwords, credentials, and so
forth.
1. The same is true after the login group is created: changes you make
to the user table in one repo in the group only propagate to the
other repos in the group when you check the “Apply changes to all
repositories“ box in the “Scope†section of the user edit screen.
Otherwise, user changes remain local to the repo you made them on.
1. Login groups only affect [the HTTP interfaces][wo]. Contrast things
like `ssh://` clones, where unless you [go out of your way][sh] to
force them to run over one of the HTTP interfaces that pays
attention to Fossil’s RBAC system, login groups aren’t consulted.
## Interactions
These restrictions combine in subtle and interesting ways. Examples:
* **#1 and #2**: If you are logged into repo C as “charlie†and then
try to visit joined repo A where “charlie†doesn’t exist, your valid
login on C won’t get you into A.
* **#2 and #3**: If “alice†exists in both of these same repos,
logging in on A gets her into C, but if she has different user
capabilities on each from the time before the two repos joined the
login group, her caps on A don’t apply to C, nor vice versa.
Let us say F is a forum-only repo, and W is a wiki-only repo, and
that Alice has forum-posting rights on F and wiki-editing rights on
W. If both repos are joined by a login group, Alice can log in on F
and then access W without logging in on it separately, but she
cannot then post a forum message on W even though she could on F.
* **#3 and #4**: If you change the caps for user “alice†on one repo
in a group and tell Fossil to apply the changes to all repos in the
group, the new caps will *overwrite* those on the other repos, not
merge with them.
To extend the practical example from the prior point, let us say you
wish to grant Alice the “write unversioned†capability on both F and
W. If you check that single user cap box on F plus the “apply to
all†option, then “Apply Changes,†she will end up with forum +
unversioned caps on repo W, losing her wiki-editing caps in the
process.
If you want user caps to differ on each repo, you must administer
them separately even if there is a common subset of caps between all
repos in the group for that user. Remember: selecting the “apply to
all†box calls for an overwrite operation, not a merge.
* **#4 and #1**: If you make a change to an existing user “bob†in
repo B and select the “apply to all†option, it will only affect
other repos in the group that have a user “bob†configured.
But, if you are instead creating user “bob†for the first time and
select that option, that user *will* be created in all repos. The
same is true of user deletion: that destructive action will
propagate through the group if you request it.
* **#5 and #1**: If you have a user “daisy†on both repos A and B in a
login group, logging in over the web to A doesn’t let you push
changes into B over SSH. Without the workaround linked above, SSH
only pays attention to the operating system’s user authentication
system, not Fossil’s.
Inversely, if Daisy successfully logs in over SSH to repo B, she
gains no access to any of the other repos in that group. She needs
at least one valid login over HTTP to one of the group’s repos.
## Discussion
The end result of all of this is that you can have a subset of users
with credentials only on repo A, a different subset only on B, and a
third subset common to both. The only thing selecting which case applies
is restriction #1 above.
Login groups have names. A repo can be in only one of these named login
groups at a time.
Trust in login groups is transitive within a single server. Consider
this sequence:
$ cd /path/to/A/checkout
$ fossil login-group join --name G ~/museum/B.fossil
$ cd /path/to/C/checkout
$ fossil login-group join ~/museum/B.fossil
That creates login group G joining repo A to B, then joins C to B.
Although we didn’t explicitly tie C to A, a successful login on C gets
you into both A and B, within the restrictions set out above.
Changes are transitive in the same way, provided you check that “apply
to all†box on the user edit screen.

<p>Here we document each currently-defined user capability character in
more detail than the brief summary on the <a
href="/setup_ucap_list">“key†page</a> in the Fossil user editor. Each
row gives the capability letter used in the Fossil user editor followed
by the C code’s name for that cap within the <tt>FossilUserPerms</tt>
object, so you can use this reference both from the UI down and from the
C code up.</p>
<p>The <a href="https://en.wikipedia.org/wiki/Mnemonic">mnemonics</a>
given here vary from obviously-correct to <i>post facto</i>
rationalizations to the outright fanciful. To <a

<title>CGI Script Configuration Options</title>
<h1>Summary</h1>
It is not necessary to have a central server in order to use Fossil.
But a central server can help a project run more smoothly by giving developers
a common point of rendezvous for syncing, and by providing a web-based
portal where developers and non-developers alike can learn about the
project and its current state.
Setting up a server using Fossil is easy.
A [./server/|separate document] talks about all of the many different methods for
setting up a Fossil server, one of which is [./server/any/cgi.md | as a CGI
script]. CGI is the technique that the three
[./selfhost.wiki|self-hosting Fossil repositories] all use.
Setting up a Fossil server using CGI is mostly about writing a short
script (usually just 2 lines) in the cgi-bin folder of an ordinary
web-server. But there are a lot of extra options that can be added
to this script, to customize the configuration. This article describes
those options.
<h1>CGI Script Options</h1>
The CGI script used to launch a Fossil server will usually look something
like this:
<verbatim>
#!/usr/bin/fossil
repository: /home/www/fossils/myproject.fossil
</verbatim>
Of course, pathnames will likely be different. The first line
(the "[wikipedia:/wiki/Shebang_(Unix)|shebang]")
always gives the name of the Fossil executable. Subsequent lines are of
the form "<b>property: argument ...</b>".
The remainder of this document describes the available properties and
their arguments.
<hr>
<h2 id="repository">repository: <i>PATH</i></h2>
This property defines the Fossil repository that the server will use.
Every Fossil CGI requires either this property or the
[#directory|<b>directory:</b>] property (but not both).
Many Fossil CGI scripts have this one property and no other.
<h2 id="directory">directory: <i>PATH</i></h2>
The PATH is the name of a directory that contains one or more Fossil
repository files having the suffix ".fossil". If this property is
used instead of [#repository|<b>repository:</b>], then the Fossil
server is able to serve all of the repositories in the directory. The
specific repository used is selected by a prefix on the PATH_INFO. See
the notes for the [#repolist|<b>repolist</b>] option regarding name
collisions between subdirectories and repository files.
<h2 id="notfound">notfound: <i>URL</i></h2>
If the [#directory|<b>directory:</b>] option is used and if the PATH_INFO
of the HTTP request does not correspond to any Fossil repository, then
the request redirects to URL.
<h2 id="repolist">repolist</h2>
This is a Boolean property.
If it is present, and if the [#directory:|<b>directory:</b>] option is used,
and if the PATH_INFO string is empty, then Fossil will show a list
of available Fossil repositories.
The "skin" of the reply is determined by the first
repository in the list that has a non-zero
[/help?cmd=repolist-skin|repolist-skin] setting.
If no repository has such a non-zero repolist-skin setting, then
the repository list is generic HTML without any decoration.
The repolist-generated page recurses into subdirectories and will list
all <tt>*.fossil</tt> files found, with the following exceptions:
* Filenames starting with a period are treated as "hidden" and skipped.
* Subdirectory names which match the base name of a fossil file in
the same directory are listed in the resulting page but are not
hyperlinked because the links would be ambiguous and the
repositories in the subdirectories would be unreachable to
clients. For example, any repositories under subdirectory
<tt>XYZ</tt> are unreachable if <tt>XYZ.fossil</tt> exists in
the same directory as <tt>XYZ</tt>, noting that this particular
name check is case-insensitive. The entries for such
repositories are clearly marked in the repolist page's output to
make the user aware of the problem. To make them accessible,
move them into a directory which does not share a base name with
a repository file.
<h2 id="localauth">localauth</h2>
This is a Boolean property.
If it is present, [./caps/ref.html#s | setup capability]
is granted to any HTTP request that
comes in over a loopback interface, such as 127.0.0.1.
<h2 id="skin">skin: <i>NAME</i></h2>
If NAME is the name of one of the built-in skins supported by Fossil,
then this option causes Fossil to display using that built-in skin,
and to ignore any custom skin that might be configured in the repository
itself.
So, if you wanted to set up a server for a single Fossil project, but
also give users the option to use several of the different built-in
skins, you could create multiple CGI scripts, each with a different
"<b>skin:</b>" property, but all pointing to the same <b>repository:</b>.
Then users can select which skin to use by using the appropriate CGI.
<h2 id="files">files: </i>GLOBLIST</i></h2>
The GLOBLIST argument is a comma-separate list of "globs" that specify
filenames. In [#directory|<b>directory:</b> mode], if the PATH_INFO
does not identify any Fossil repository, but it does refer some other
file in the directory, and that filename matches one of the glob patterns
in the GLOBLIST, then the file is returned as static content.
<h2 id="setenv">setenv: <i>NAME VALUE</i></h2>
This parameter causes additional environment variable NAME to have VALUE.
This parameter can be repeated as many times as necessary.
<h2 id="HOME">HOME: <i>PATH</i></h2>
This parameter is a short-hand for "<b>setenv HOME <i>PATH</i></b>".
<h2 id="cgi-debug">cgi-debug: <i>FILE</i></h2>
Cause CGI-related debugging information to be appended in <i>FILE</i>. Use
this to help debug CGI problems.
<h2 id="errorlog">errorlog: <i>FILENAME</i></h2>
This setting causes the server to log any errors in FILENAME.
It is ok for multiple Fossil CGIs to share the same error log.
Setting up an error log for Fossil servers is not required, but it
is recommended.
<h2 id="timeout">timeout: <i>N</i></h2>
This property changes the timeout on each CGI request to N seconds.
If N is zero, then there is no timeout. If this property is omitted,
then the default timeout is 300 seconds (5 minutes).
<h2 id="extroot">extroot: <i>PATH</i></h2>
This property defines the DOCUMENT_ROOT for the
[./serverext.wiki|CGI Server Extensions]. If this property
is present, then CGI Server Extensions are enabled. When this
property is omitted, CGI Server Extensions are disabled.
A cascade of CGI invocations can occur here. Fossil itself is
started as CGI, then Fossil can turn around and invoke a sub-CGI
extension. The sub-CGI extension outputs reply text, when Fossil
then (optionally) augments with its own header and footer and returns
to the original requestor. The property controls the DOCUMENT_ROOT
of the sub-CGI.
<h2 id="redirect">redirect: <i>REPO URL</i></h2>
Extract the "name" query parameter and search REPO for a check-in or
ticket that matches the value of "name", then redirect to URL. There
can be multiple "redirect:" lines that are processed in order. If the
repo name is "*", then an unconditional redirect to URL is taken.
<h2 id="jsmode">jsmode: <i>VALUE</i></h2>
Specifies the delivery mode for JavaScript files. See "[/help?cmd=http |
http --jsmode]" for the allowed values and their meanings.
<h2 id="mainmenu">mainmenu: <i>FILE</i></h2>
This parameter causes the contents of the given file to override the
site's <tt>mainmenu</tt> configuration setting, in much the same way
that the <tt>skin</tt> setting overrides the skin. This can be used to
apply a common main menu to a number of sites, and centrally maintain
it, without having to copy its contents into each site. Note, however,
that the contents of this setting are not stored in the repository and
will not be cloned along with the repository.

<title>Change Log</title>
<h2 id='v2_25'>Changes for version 2.25 (2024-11-06)</h2>
* The "[/help?cmd=ui|fossil ui /]" command now works even for repositories
that have non-ASCII filenames
* Add the [/help?cmd=tree|fossil tree] command.
* On case-insensitive filesystems, store files using the filesystem's
preferred case rather than the case typed in by the user.
* Change the name "fossil cherry-pick" command to "fossil cherrypick",
which is more familiar to Git users. Retain the legacy name for
compatibility.
* Add new query parameters to the [/help?cmd=/timeline|/timeline page]:
d2=, p2=, and dp2=.
* Add options to the [/help?cmd=tag|fossil tag] command that will list tag values.
* Add the -b|--brief option to the [/help?cmd=status|fossil status] command.
* Add ability to upload unversioned files via the [/help?cmd=/uvlist|/uvlist page].
* Add history search to the [/help?cmd=/chat|/chat page].
* Add Unix socket support to the [/help?cmd=server|server command].
* On Windows, use the root certificates managed by the operating system
(requires OpenSSL 3.2.0 or greater).
* Take into account zero-width and double-width unicode characters when
formatting the command-line timeline.
* Update the built-in SQLite to version 3.47.0. Precompiled binaries are
linked against OpenSSL 3.4.0.
* Numerous minor fixes and additions.
<h2 id='v2_24'>Changes for version 2.24 (2024-04-23)</h2>
* Apache change work-around → As part of a security fix, the Apache webserver
mod_cgi module has stopped relaying the Content-Length field of the HTTP
reply header from the CGI programs back to the client in cases where the
connection is to be closed and the client is able to read until end-of-file.
The HTTP and CGI specs allow for this, though it does seem rude.
Older versions of Fossil were depending on the Content-Length header field
being set. To work around the change to Apache, Fossil has
been enhanced to cope with a missing Content-Length in the reply header. See
[forum:/forumpost/12ac403fd29cfc89|forum thread 12ac403fd29cfc89].
* [./customskin.md|Skin] enhancements:
<ul>
<li> Reworked the default skin to make everything more readable: larger
fonts, more whitespace, deeper indents to show hierarchy and to
offset command examples, etc. Adjusted colors slightly to bring
things into better accord with the WCAG accessibility guidelines.
This constitutes a <strong>breaking change</strong> for those with
custom skins; see [./customskin.md#version-2.24 | this section of
the docs] for migration advice.
<li> Add a new link added to the [/login] page that allows the user to
[/skins|select their preferred skin]. This preference is stored in
the [/fdscookie|fossil display_settings cookie].
<li> The /setup_skin_admin page is simplified to let administrators easily
select one of the built-in skins as a default, or to specify a
custom skin.
</ul>
* If an "ssh:" sync fails in a way that suggests that the fossil executable
could not be found on the remote host, then retry after adding a PATH=
prefix to the command. This helps "ssh:" to "just work" when the server
is a Mac.
* Enhancements to the [/help?cmd=/timeline|/timeline page]:
<ul>
<li> Add the x= query paramater
<li> Add the shortcut tl= and rl= query parameters
<li> Add support for from=,ft= and from=,bt= query parameter combinations
<li> Automatically highlight the endpoints for from=,to= queries.
<li> Add the to2=Z query parameter to augment from=X,to=Y so that the
path from X to Z is shown if Y cannot be found.
</ul>
* Moved the /museum/repo.fossil file referenced from the Dockerfile from
the ENTRYPOINT to the CMD part to allow use of --repolist mode.
* The [/uvlist] page now shows the hash algorithm used so that
viewers don't have to guess. The hash is shown in a fixed-width
font for a more visually pleasing display.
* If the [/help?cmd=autosync|autosync setting] contains keyword "all",
the automatic sync occurs against all defined remote repositories, not
just the default.
* Markdown formatter: improved handling of indented fenced code blocks
that contain blank lines.
* When doing a "[/help?cmd=add|fossil add]" on a system with case-insensitive
but case-preserving filenames (Mac and Windows) try to use the filename
case as it is known to the filesystem, not the case entered by the
user on the command-line. See
[forum:/forumpost/30d9c0d131610f53|forum thread 30d9c0d131610f53].
* Fix problems with one-click unsubscribe on email notifications.
* Import the latest [/doc/trunk/www/pikchr.md|Pikchr] containing support
for "diamond" objects.
* Add ability to render committed Pikchr files to SVG via
<samp>/doc/…/foo.pikchr?popup</samp> URLs.
* Update Fossil's internal robot detection logic so that it correctly
identifies the new GoogleOther crawler as a robot.
<h2 id='v2_23'>Changes for version 2.23 (2023-11-01)</h2>
* Add ability to "close" forum threads, such that unprivileged users
may no longer respond to them. Only administrators can close
threads or respond to them by default, and the
[/help?cmd=forum-close-policy|forum-close-policy setting] can be
used to add that capability to moderators.
* Add the [/help?cmd=all|fossil all whatis] command.
* The [/help?cmd=status|fossil status] command and relevant UI pages now
correctly report files which were both renamed <b>and</b> edited as such.
* Show default value of settings that have a default in
[/help?cmd=help|fossil help SETTING] output.
* On timeline graphs, show closed check-ins using an X in the middle of the
node circle or box.
* New options for email notification: Get email only for the first
post in each new thread, and/or posts that are in reply to my posts.
* Fix a regression bug introduced in version 2.22 that caused FTS5 searches
to fail for terms containing non-ASCII characters.
* Improved defense-in-depth against malicious attack:
<ul>
<li> When an attempted SQL injection attack is detected, return
HTTP result code 418, which can signal the web server to sanction
the attacking IP address.
<li> Better defense against cross-site request forgery (CSRF)
attacks.
<li> Improvements to static analysis of source code (the codecheck1.c
file in the source tree).
</ul>
* Enhance the [/help?cmd=/dir|treeview file listings]
([/dir?type=tree&ci=trunk|example]) by displaying file sizes
and adding the option to sort by file size.
* The [/help?cmd=fts-config|fossil fts-config] command now shows how much
repository space is used by the full-text index.
* Changing a setting to an empty string is now the same as deleting the
setting, in most cases. There are a few exceptions, indicated by the
keep-empty flag on the setting definition.
* The [/help?cmd=branch|fossil branch list] command can now filter branches
that have/have not been merged into the current branch.
* Improvements to interactions with remote repositories over SSH:
<ul>
<li> Print the text of the SSH command that is run to do remote interaction,
for full disclosure to the operator.
<li> Add a PATH= argument to the [/help?cmd=ui|fossil ui remote:/] and
[/help?cmd=patch|fossil patch push/pull remote:...] commands so that
they work when the "remote" machine is a Mac and the "fossil"
executable is in the $HOME/bin directory.
</ul>
* Update built-in libraries SQLite, ZLib, Pikchr to their latest versions.
* Documentation enhancements and typo fixes.
<h2 id='v2_22'>Changes for version 2.22 (2023-05-31)</h2>
* Enhancements to the [/help?cmd=/timeline|/timeline webpage]: <ol type="a">
<li> Add the ft=TAG query parameter which in combination with d=Y
shows all descendants of Y up to TAG
<li> Enhance the s=PATTERN (search) query parameter so that forum post
text is also searched when the "vfx" query parameter is used
<li> Fix the u= (user) query parameter so that it works with a= and b=
<li> Add the oldestfirst query parameter to show the events in reverse order.
Useful in combination with y=f and vfs and perhaps also u= to show all
forum events in chronological order
<li> For the p=X and bt=Y query parameter combination, if Y is a tag that
identifies multiple check-ins, search backwards in time for Y beginning
at X
</ol>
* Administrators can select to skip sending notifications about new forum
posts.
* If the value N is negative in "--context N" or "-c N" to the various diff
commands, then treat it as infinite and show the complete file content.
* The stock OCI container no longer includes BusyBox, thus no longer
needs to start as root to chroot that power away. That in turn
frees us from needing to build and install the container as root,
since it no longer has to create a private <tt>/dev</tt> tree
inside the jail for Fossil's use.
* Add support for the trigram tokenizer for FTS5 search to enable
searching in Chinese.
* Comment lines (starting with a '#') are now supported inside
[./settings.wiki#versionable|versioned settings].
* Default permissions for anonymous users in new repositories are
changed to "hz".
* The [/help?cmd=status|fossil status] command now detects when a
file used to be a symlink and has been replaced by a regular file.
(It previously checked for the inverse case only.)
* The [/help?cmd=empty-dirs|empty-dirs setting] now reuses the same
parser as the *-glob settings instead of its prior idiosyncratic
parser, allowing quoted whitespace in patterns.
* Enhancements to the [/help?cmd=/reports|/reports webpage]:
<ol type="a">
<li> The by-week, by-month, and by-year options now show an estimated
size of the current week, month, or year as a dashed box.
<li> New sub-categories "Merge Check-ins" and "Non-Merge Check-ins".
</ol>
<h2 id='v2_21'>Changes for version 2.21 (2023-02-25)</h2>
* Users can request a password reset. This feature is disabled by default.
Use the new [/help?cmd=self-pw-reset|self-pw-reset property] to enable it.
New web pages [/help?cmd=/resetpw|/resetpw] and
[/help?cmd=/reqpwreset|/reqpwreset] added.
* Add the [/help?cmd=repack|fossil repack] command (together with
[/help?cmd=all|fossil all repack]) as a convenient way to optimize the
size of one or all of the repositories on a system.
* Add the ability to put text descriptions on ticket report formats.
* Upgrade the test-find-pivot command to the [/help/merge-base|merge-base command].
* The [/help?cmd=/chat|/chat page] can now embed fossil-rendered
views of wiki/markdown/pikchr file attachments with the caveat that such
embedding happens in an iframe and thus does not inherit styles and such
from the containing browser window.
* The [/help?cmd=all|fossil all remote] subcommand added to "fossil all".
* Passwords for remembered remote repositories are now stored as irreversible
hashes rather than obscured clear-text, for improved security.
* Add the "nossl" and "nocompress" options to CGI.
* Update search infrastructure from FTS4 to FTS5.
* Add the [/help?cmd=/deltachain|/deltachain] page for debugging purposes.
* Writes to the database are disabled by default if the HTTP request
does not come from the same origin. This enhancement is a defense in depth
measure only; it does not address any known vulnerabilities.
* Improvements to automatic detection and mitigation of attacks from
malicious robots.
<h2 id='v2_20'>Changes for version 2.20 (2022-11-16)</h2>
* Added the [/help?cmd=chat-timeline-user|chat-timeline-user setting]. If
it is not an empty string, then any changes that would appear on the timeline
are announced in [./chat.md|the chat room].
* The /unsubscribe page now requests confirmation. [./alerts.md|Email notifications]
now contain only an "Unsubscribe" link, and not a link to subscription management.
* Added the "[/help?cmd=branch|fossil branch lsh]" subcommand to list the
most recently modified branches.
* More elements of the /info page are now inside of an accordion.
* Replace the <tt>--dryrun</tt> flag with <tt>--dry-run</tt> in all
commands which still used the former name, for consistency.
* Rebuilt [/file/Dockerfile | the stock Dockerfile] to create a "from scratch"
Busybox based container image via an Alpine Linux intermediary
* Added [/doc/trunk/www/containers.md | a new document] describing how to
customize, use, and run that container.
* Added "by hour of day" report to [/reports?view=byhour|the /reports page].
* Improved correctness, usability, and efficiency for the case
[/timeline?r=deltify-tkt-blobs|when values in a TICKET's column
tend to be long and volatile].
* Fixed a bug [/info/ea5afad31f478396 | introduced in 2.17] that
prevented <tt>clone --unversioned</tt> from completing the
retrieval of UV files from the remote repo. While fixing that, enabled
UV tracing output with <tt>clone --unversioned --verbose</tt>, making it
consonant with <tt>uv sync --verbose</tt>.
<h2 id='v2_19'>Changes for version 2.19 (2022-07-21)</h2>
* On file listing pages, sort filenames using the "uintnocase" collating
sequence, so that filenames that contains embedded integers sort in
numeric order even if they contain a different number of digits.
(Example: "fossil_80_..." comes before "fossil_100.png" in the
[/dir?ci=92fd091703a28c07&name=skins/blitz|/skins/blitz] directory listing.)
* Enhancements to the graph layout algorithm design to improve readability
and promote better situational awareness.
* Performance enhancement for the
[./checkin_names.wiki#root|"root:BRANCHNAME" style of tag],
accomplished using a Common Table Expression in the underlying SQL.
* Sort tag listings (command line and webpage) by taking numbers into
consideration so as to cater for tags that follow semantic versioning.
* On the wiki listings, omit by default wiki pages that are associated with
check-ins and branches.
* Add the new "[/help?cmd=describe|fossil describe]" command.
* Markdown subsystem extended with [../src/markdown.md#ftnts|footnotes support].
See corresponding [../test/markdown-test3.md|test cases],
[/wiki?name=branch/markdown-footnotes#il|known limitations] and
[forum:/forumthread/ee1f1597e46ec07a|discussion].
* Add the new special name "start:BRANCH" to refer to the first check-in of
the branch.
* Support [/wiki?name=branch/generated-tkt-mimetype&p|generated "mimetype"]
columns in the <var>TICKET</var> and <var>TICKETCHNG</var> tables.
* Fix [/timeline?r=fix_remote_url_overwrite_with_proxy|remote-url-overwrite]
bug where remote-url is overwritten by the proxy setting during sync
operation. Also require explicit "system" proxy setting to use
"http_proxy" environment variable.
* Reimplemented the [/pikchrshow] app to use a WebAssembly build of
pikchr so that it can render pikchrs on the client instead of requiring
a server round-trip.
* Add the [/help?cmd=email-listid|email-listid setting]. If set, it is
used as the List-ID header for all outbound notification emails.
* Add the "--branch" option to the "[/help?cmd=timeline|timeline]" command
to restrict the displayed items to a specific branch.
* Add the "--versions" option to "[/help?cmd=diff|fossil diff]"
to display details about the compared versions into the patch header.
* Numerous other minor enhancements.
<h2 id='v2_18'>Changes for version 2.18 (2022-02-23)</h2>
* Added support for [./ssl-server.md|SSL/TLS server mode] for commands
like "[/help?cmd=server|fossil server]" and "[/help?cmd=http|fossil http]"
* The new [/help?cmd=cherry-pick|cherry-pick command] is an alias for
[/help?cmd=merge|merge --cherrypick].
* Add new setting "[/help?cmd=large-file-size|large-file-size]". If the size
of any file in a commit exceeds this size, a warning is issued.
* Query parameter "year=YYYY" is now accepted by [/help?cmd=/timeline|/timeline].
* The [/help?cmd=tar|tar] and [/help?cmd=zip|zip commands] no longer
sterilize the manifest file.
* Further improvement to diff alignment in cases that involve both
edits and indentation changes.
* [/doc/trunk/www/chat.md|Chat] improvements:<ul>
<li> [/help?cmd=/chat|The /chat page] input options have been reworked
again for better cross-browser portability.
<li> When sending a [/help?cmd=/chat|/chat] message fails, it is no longer
immediately lost and sending may optionally be retried.
<li> [/help?cmd=/chat|/chat] can now optionally embed attachments of certain
types directly into message bodies via an iframe.
<li> Add the "--as FILENAME" option to the "[/help?cmd=chat|fossil chat send]"
command.
<li> Added the "[/help?cmd=chat|fossil chat pull]" command, available to
administrators only, for backing up the chat conversation.
</ul>
* Promote the test-detach command into the [/help?cmd=detach|detach command].
* For "[/help?cmd=pull|fossil pull]" with the --from-parent-project option,
if no URL is specified then use the last URL from the most recent prior
"fossil pull --from-parent-project".
* Add options --project-name and --project-desc to the
"[/help?cmd=init|fossil init]" command.
* The [/help?cmd=/ext|/ext page] generates the SERVER_SOFTWARE environment
variable for clients.
* Fix the REQUEST_URI [/doc/trunk/www/aboutcgi.wiki#cgivar|CGI variable] such
that it includes the query string. This is how most other systems understand
REQUEST_URI.
* Added the --transport-command option to [/help?cmd=sync|fossil sync]
and similar.
<h2 id='v2_17'>Changes for version 2.17 (2021-10-09)</h2>
* Major improvements to the "diff" subsystem, including: <ul>
<li> Added new [/help?cmd=diff|formatting options]: --by, -b, --webpage, --json, --tcl.
<li> Partial-line matching for unified diffs
<li> Better partial-line matching for side-by-side diffs
<li> Buttons on web-based diffs to show more context
<li> Performance improvements
</ul>
* The --branchcolor option on [/help?cmd=commit|fossil commit] and
[/help?cmd=amend|fossil amend] can now take the value "auto" to
force Fossil to use its built-in automatic color choosing algorithm.
* Fossil now [./concepts.wiki#workflow|autosyncs] prior to running
[/help?cmd=open|fossil open].
* Add the [/help?cmd=ticket-default-report|ticket-default-report setting],
which if set to the title of a ticket report causes that ticket report
to be displayed below the search box in the /ticket page.
* The "nc" query parameter to the [/help?cmd=/timeline|/timeline] page
causes all graph coloring to be omitted.
* Improvements and bug fixes to the new "[/help?cmd=ui|fossil ui REMOTE]"
feature so that it works better on a wider variety of platforms.
* In [/help?cmd=/wikiedit|/wikiedit], show the list of attachments for
the current page and list URLs suitable for pasting them into the page.
* Add the --no-http-compression option to [/help?cmd=sync|fossil sync]
and similar.
* Print total payload bytes on a [/help?cmd=sync|fossil sync] when using
the --verbose option.
* Add the <tt>close</tt>, <tt>reopen</tt>, <tt>hide</tt>, and
</tt>unhide</tt> subcommands to [/help?cmd=branch|the branch command].
* The "-p" option to [/help?cmd=branch|fossil branch list] shows only
private branches.
* The [/md_rules|Markdown formatter] now interprets the content of
block HTML markup (such as <table>) in most cases. Only content
of <pre> and <script> is passed through verbatim.
* The [/help?cmd=wiki|wiki list command] no longer lists "deleted"
pages by default. Use the new <tt>--all</tt> option to include deleted
pages in the output.
* The [/help?cmd=all|fossil all git status] command only shows reports for
the subset of repositories that have a configured Git export.
* The [/help?cmd=/chat|/chat] configuration was reimplemented and
provides new options, including the ability for a repository
administrator to
[./chat.md#notifications|extend the selection of notification sounds]
using unversioned files.
* Chat now uses fossil's full complement of markdown features,
instead of the prior small subset of markup it previously supported.
This retroactively applies to all chat messages, as they are
markdown-processed when they are sent instead of when they
are saved.
* Added a chat message preview mode so messages can be previewed
before being sent. Similarly, added a per-message ability to view
the raw un-parsed message text.
* The hotkey to activate preview mode in [/help?cmd=/wikiedit|/wikiedit],
[/help?cmd=/fileedit|/fileedit], and [/help?cmd=/pikchrshow|/pikchrshow]
was changed from ctrl-enter to shift-enter in order to align with
[/help?cmd=/chat|/chat]'s new preview feature and related future
changes.
<h2 id='v2_16'>Changes for Version 2.16 (2021-07-02)</h2>
* <b>Security:</b> Fix the client-side TLS so that it verifies that the
server hostname matches its certificate.
* The default "ssh" command on Windows is changed to "ssh" instead of the
legacy "plink", as ssh is now generally available on Windows systems.
Installations that still need to use the legacy "plink" can make that
happen by running: '<tt>fossil set ssh-command "plink -ssh" --global</tt>'.
* Added the [./patchcmd.md|fossil patch] command.
* The [/help?cmd=ui|fossil ui] command is enhanced in multiple ways:<ol>
<li> The REPOSITORY argument can be the name of a check-out directory.
<li> If the REPOSITORY argument is prefixed by "HOST:" or "USER@HOST:"
then the ui is run on the remote machine and tunnelled back to the local
machine using ssh. (The latest version of fossil must be installed on
both the local and the remote for this to work correctly.)
<li> The new --nobrowser and --fossilcmd options is provided.
</ol>
* The [/brlist|/brlist web page] allows the user to
select multiple branches to be displayed together in a single
timeline.
* The [./forum.wiki|Forum] provides a hyperlink on the author of each
post that goes to a timeline of recent posts by that same author.
* Added the "[/help?cmd=bisect|fossil bisect run]" command for improved
automation of bisects.
* The [/help?cmd=merge|fossil merge] command now does a better job merging
branches where files have been renamed between the current branch and the
branch being merged.
* The [/help?cmd=open|fossil open] command allows the repository file
to be inside the working directory without requiring the --force flag.
* The [/help?cmd=/wikiedit|/wikiedit] and [/help?cmd=/wikinew|/wikinew]
pages now default to markdown format.
* The [/help?cmd=/login|/login] page now links to a user's forum post
timeline if the repository has forum posts.
* Tags may now be propagated for forum posts, wiki pages, and technotes.
The [/help?cmd=tag|tag command] can now manipulate and list such tags.
* [./caps/login-groups.md|Login-Groups] are now shown on the repository
list of the "[/help?cmd=all|fossil all ui]" command.
* Administrators can configure [./alerts.md|email alerts] to expire
a specific number of days (ex: 365) after the last user contact with
the Fossil server. This prevents alert emails being sent to
abandoned email accounts forever.
* SQL that defines [/tktsetup_tab|database objects for tickets] now
[/timeline?c=c717f1ef9a1a4c91|can DROP] a VIEW or an INDEX provided
that its name starts with '<code>ticket</code>' or '<code>fx_</code>'.
* Update the built-in SQLite to version 3.36.0.
* Numerous other minor enhancements.
<h2 id='v2_15'>Changes for Version 2.15 (2021-03-26) and Patch 2.15.1 on (2021-04-07)
and 2.15.2 on (2021-06-15)</h2>
* <b>Patch 2.15.2:</b> Fix the client-side TLS so that it verifies that the
server hostname matches its certificate. <b>Upgrading to
the patch is recommended.</b>
* <b>Patch 2.15.1:</b> Fix a data exfiltration bug in the server. <b>Upgrading to
the patch is recommended.</b>
* The [./defcsp.md|default CSP] has been relaxed slightly to allow
images to be loaded from any URL. All other resources are still
locked down by default.
* The built-in skins all use the "[/help?cmd=mainmenu|mainmenu]"
setting to determine the content of the main menu.
The ability to edit the
"mainmenu" setting is added on the /Admin/Configuration page.
* The hamburger menu is now available on most of the built-in skins.
* Any built-in skin named "X" can be used instead of the standard
repository skin by adding the URL parameter <tt>skin=X</tt> to the
request. The selection is persisted using the display
preferences cookie unless the "once" query parameter is also
included. The [/skins] page may be used to select a skin.
* The [/cookies] page now gives the user an opportunity to delete
individual cookies. And the /cookies page is linked from the
/sitemap, so that it appears in hamburger menus.
* The [/sitemap] extensions are now specified by a single new
"[/help?cmd=sitemap-extra|sitemap-extra setting]",
rather than a cluster of various
"sitemap-*" settings. The older settings are no longer used.
<b>This change might require minor server configuration
adjustments on servers that use /sitemap extensions.</b>
The /Admin/Configuration page provides the ability to edit
the new "sitemap-extra" setting.
* Added the "--ckout-alias NAME" option to
[/help?cmd=ui|fossil ui], [/help?cmd=server|fossil server], and
[/help?cmd=http|fossil http]. This option causes Fossil to
understand URIs of the form "/doc/NAME/..." as if they were
"[/help?cmd=/doc|/doc/ckout/...]", to facilitate testing of
[./embeddeddoc.wiki|embedded documentation] changes prior to
check-in.
* For diff web pages, if the diff type (unified versus side-by-side)
is not specified by a query parameter, and if the
"[/help?cmd=preferred-diff-type|preferred-diff-type]"
setting is omitted or less than 1, then select the diff type based
on a guess of whether or not the request is coming from a mobile
device. Mobile gets unified and desktop gets side-by-side.
* The various pages which show diffs now have toggles to show/hide
individual diffs.
* Add the "[/help?cmd=preferred-diff-type|preferred-diff-type]"
setting to allow an admin to force a default diff type.
* The "pikchr-background" setting is now available in
"detail.txt" skin files, for better control of Pikchr
colors in inverted color schemes.
* Add the <tt>--list</tt> option to the
[/help?cmd=tarball|tarball],
[/help?cmd=zip|zip], and [/help?cmd=sqlar|sqlar]
commands.
* The javascript used to implement the hamburger menu on the
default built-in skin has been made generic so that it is usable
by a variety of skins, and promoted to an ordinary built-in
javascript file.
* New TH1 commands:
"[/doc/trunk/www/th1.md#bireqjs|builtin_request_js]",
"[/doc/trunk/www/th1.md#capexpr|capexpr]",
"foreach", "lappend", and "string match"
* The [/help/leaves|leaves command] now shows the branch point
of each leaf.
* The [/help?cmd=add|fossil add] command refuses to add files whose
names are reserved by Windows (ex: "aux") unless the --allow-reserved
option is included. This helps prevent Unix users from accidentally
creating check-ins that are unreadable by Windows users.
* Add the "re=" query parameter to the [/help?cmd=/dir|/dir] webpage,
for symmetry with the [/help?cmd=/tree|/tree] page.
* Update the built-in SQLite to version 3.35.0.
* The ./configure script now has the --print-minimum-sqlite-version option
that prints the minimum SQLite version required by the current version
of Fossil. This might be used by integrators who insist on building
Fossil to link against the system SQLite library rather than the
built-in copy of SQLite, to verify that their system SQLite library
is recent enough.
* Webpage that shows [/help?cmd=/whistory|history of a wiki page]
gained client-side UI to help with comparison between two arbitrary
versions of a wiki (by the means of anchoring a "baseline" version)
and the ability to squeeze several sequential edits made by the same
user into a single "recycled" row (the latest edit in that sequence).
<h2 id='v2_14'>Changes for Version 2.14 (2021-01-20) and Patch 2.14.1 on (2021-04-07)
and 2.14.2 on (2021-06-15)</h2>
* <b>Patch 2.14.2:</b> Fix the client-side TLS so that it verifies that the
server hostname matches its certificate. <b>Upgrading to
the patch is recommended.</b>
* <b>Patch 2.14.1:</b> Fix a data exfiltration bug in the server.
<b>Upgrading to the patch is recommended.</b>
* <b>Schema Update Notice #1:</b>
This release drops a trigger from the database schema (replacing
it with a TEMP trigger that is created as needed). This
change happens automatically the first time you
add content to a repository using Fossil 2.14 or later. No
action is needed on your part. However, if you upgrade to
version 2.14 and then later downgrade or otherwise use an earlier
version of Fossil, the email notification mechanism may fail
to send out notifications for some events, due to the missing
trigger. If you want to
permanently downgrade an installation, then you should run
"[/help?cmd=rebuild|fossil rebuild]" after the downgrade
to get email notifications working again. If you are not using
email notification, then the schema change will not affect you in
any way.
* <b>Schema Update Notice #2:</b>
This release changes how the descriptions of wiki edits are stored
in the EVENT table, for improved display on timelines. You must
run "[/help?cmd=rebuild|fossil rebuild]" to take advantage of
this enhancement. Everything will still work without
"fossil rebuild", except you will get goofy descriptions of
wiki updates in the timeline.
* Add support for [./chat.md|Fossil chat].
* The "[/help?cmd=clone|fossil clone]" command is enhanced so that
if the repository filename is omitted, an appropriate name is derived
from the remote URL and the newly cloned repo is opened. This makes
the clone command work more like Git, thus making it easier for
people transitioning from Git.
* Added the --mainbranch option to the [/help?cmd=git|fossil git export]
command.
* Added the --format option to the
"[/help?cmd=timeline|fossil timeline]" command.
* Enhance the --numstat option on the
"[/help?cmd=diff|fossil diff]" command so that it shows a total
number of lines added and deleted and total number of files
modified.
* Add the "contact" sub-command to [/help?cmd=user|fossil user].
* Added commands "[/help?cmd=all|fossil all git export]" and
"[/help?cmd=all|fossil all git status]".
* Added the "df=CHECKIN" query parameter to the
[/help?cmd=/timeline|/timeline page].
* Improvements to the "[/sitemap]" page. Add subpages
[/sitemap-timeline] and [/sitemap-test].
* Better text position in cylinder objects of Pikchr diagrams.
* New "details.txt" settings available to custom skins to better control
the rendering of Pikchr diagrams:
<ul>
<li> pikchr-foreground
<li> pikchr-scale
<li> pikchr-fontscale
</ul>
* Allow the use of SQL functions inside the ticket table definition
for custom ticket configurations.
* The built-in SQLite is updated to version 3.35.0 alpha containing
performance optimizations, especially performance associated with
startup, and minor improvements to the CLI.
* Performance optimizations to Fossil itself.
* Countless improvements and enhancements to the documentation
<h2 id='v2_13'>Changes for Version 2.13 (2020-11-01)</h2>
* Added support for [./interwiki.md|interwiki links].
* Enable <del> and <ins> markup in wiki.
* Improvements to the Forum threading display.
* Added support for embedding [./pikchr.md|pikchr]
markup in markdown and fossil-wiki content.
* The new "[/help?cmd=pikchr|pikchr]" command can render
pikchr scripts, optionally pre-processed with
[/doc/trunk/www/th1.md|TH1] blocks and variables exactly like
site skins are.
* The new [/help?cmd=/pikchrshow|pikchrshow] page provides an
editor and previewer for pikchr markup.
* In [/help?cmd=/wikiedit|/wikiedit] and
[/help?cmd=/fileedit|/fileedit], Ctrl-Enter can now be used
initiate a preview and to toggle between the editor and preview
tabs.
* The <tt>/artifact</tt> and <tt>/file</tt> views, when in
line-number mode, now support interactive selection of a range
of lines to hyperlink to.
* Enhance the [/help?cmd=/finfo|/finfo] webpage so that when query
parameters identify both a filename and a checkin, the resulting
graph tracks the identified file across renames.
* The built-in SQLite is updated to an alpha of version 3.34.0, and
the minimum SQLite version is increased to 3.34.0 because the
/finfo change in the previous bullet depends on enhancements to
recursive common table expressions that are only available in
SQLite 3.34.0 and later.
* Countless other minor refinements and documentation improvements.
<h2 id='v2_12'>Changes for Version 2.12.1 (2020-08-20)</h2>
* (2.12.1): Fix client-side vulnerabilities discovered by Max Justicz.
* Security fix in the "[/help?cmd=git|fossil git export]" command.
The same fix is also backported to version 2.10.1 and 2.11.1.
New "safety-net" features were added to prevent similar problems
in the future.
* Enhancements to the graph display for cases when there are
many cherry-pick merges into a single check-in.
[/timeline?f=2d75e87b760c0a9|Example]
* Enhance the [/help?cmd=open|fossil open] command with the new
--workdir option and the ability to accept a URL as the repository
name, causing the remote repository to be cloned automatically.
Do not allow "fossil open" to open in a non-empty working directory
unless the --keep option or the new --force option is used.
* Enhance the markdown formatter to more closely follow the
[https://spec.commonmark.org/0.29/#emphasis-and-strong-emphasis|CommonMark specification]
with regard to text highlighting.
Underscores in the middle of identifiers (ex: fossil_printf())
no longer need to be escaped.
* The markdown-to-html translator can prevent unsafe HTML
(for example: <script>) on user-contributed pages like forum and
tickets and wiki. The admin can adjust this behavior using
the [/help?cmd=safe-html|safe-html setting] on the Admin/Wiki page.
The default is to disallow unsafe HTML everywhere.
[https://fossil-scm.org/forum/forumpost/3714e6568f|Example].
* Added the "collapse" and "expand" capability for long forum posts.
[https://fossil-scm.org/forum/forumpost/9297029862|Example]
* The "[/help?cmd=remote-url|fossil remote]" command now has options for
specifying multiple persistent remotes with symbolic names. Currently
only one remote can be used at a time, but that might change in the
future.
* Add the "Remember me?" checkbox on the login page. Use a session
cookie for the login if it is not checked.
* Added the experimental "[/help?cmd=hook|fossil hook]" command for
managing "hook scripts" that run before checkin or after a push.
* Enhance the [/help?cmd=revert|fossil revert] command so that it
is able to revert all files beneath a directory.
* Add the [/help?cmd=bisect|fossil bisect skip] command.
* Add the [/help?cmd=backup|fossil backup] command.
* Enhance [/help?cmd=bisect|fossil bisect ui] so that it shows all unchecked
check-ins in between the innermost "good" and "bad" check-ins.
* Added the <tt>--reset</tt> flag to the "[/help?cmd=add|fossil add]",
"[/help?cmd=rm|fossil rm]", and
"[/help?cmd=addremove|fossil addremove]" commands.
* Added the "<tt>--min</tt> <i>N</i>" and "<tt>--logfile</tt> <i>FILENAME</i>"
flags to the [/help?cmd=backoffice|backoffice] command, as well as other
enhancements to make the backoffice command a viable replacement for
automatic backoffice. Other incremental backoffice improvements.
* Added the [/help?cmd=/fileedit|/fileedit page], which allows
editing of text files online. Requires explicit activation by
a setup user.
* Translate built-in help text into HTML for display on web pages.
[/help?cmd=help|Example].
* On the [/help?cmd=/timeline|/timeline] webpage, the combination
of query parameters "p=CHECKIN" and "bt=ANCESTOR" draws all
ancestors of CHECKIN going back to ANCESTOR. For example,
[/timeline?p=202006271506&bt=version-2.11] shows all ancestors
of the checkin that occurred on 2020-06-27 15:06 going back to
the 2.11 release.
* Update the built-in SQLite so that the
"[/help?cmd=sql|fossil sql]" command supports new output
modes ".mode box" and ".mode json".
* Add the "<tt>obscure()</tt>" SQL function to the
"[/help?cmd=sql|fossil sql]" command.
* Added virtual tables "<tt>helptext</tt>" and "<tt>builtin</tt>" to
the "[/help?cmd=sql|fossil sql]" command, providing access to the
dispatch table including all help text, and the builtin data files,
respectively.
* [./delta_format.wiki|Delta compression] is now applied to forum edits.
* The [/help?cmd=/wikiedit|wiki editor] has been modernized and is
now Ajax-based. The WYSIWYG editing option for Fossil-format wiki
pages was removed. (Please let us know, via the site's Forum menu,
if that removal unduly impacts you.) This also changes the semantics
of the wiki "Sandbox": that pseudo-page may be freely edited but
no longer saved via the UI (the [/help?cmd=wiki|wiki CLI command]
can, though).
* The [/help?cmd=allow-symlinks|allow-symlinks setting] no longer
syncs. It must be activated individually on any clones which require
symlinks.
* Countless documentation enhancements.
<h2 id='v2_11'>Changes for Version 2.11 (2020-05-25)</h2>
* (2.11.2): Backport security fixes from 2.12.1
* (2.11.1): Backport security fix for the "fossil git export" command.
* Support [/md_rules|Markdown] in the default ticket configuration.
* Timestamp strings in [./checkin_names.wiki|object names]
can now omit punctation. So, for example, "202004181942" and
"2020-04-18 19:42" mean the same thing.
* Enhance backlink processing so that it works with Markdown-formatted
tickets and so that it works for wiki pages.
Ticket [a3572c6a5b47cd5a].
<ul><li> "[/help?cmd=rebuild|fossil rebuild]" is needed to
take full advantage of this fix. Fossil will continue
to work without the rebuild, but the new backlinks will be missing.</ul>
* The algorithm for finding the
[./tech_overview.wiki#configloc|location of the configuration database]
is enhanced to be XDG-compliant.
* Add a hide/show feature to
[./wikitheory.wiki#assocwiki|associated wiki] display on
check-in and branch information pages.
* Enhance the "[/help?cmd=info|fossil info]" command so that it
works with no arguments even if not within an open check-out.
* Many improvements to the forum and especially email notification
of forum posts, in response to community feedback after switching
SQLite support from a mailing list over to the forum.
* Minimum length of a self-registered user ID increased from 3 to 6
characters.
* When the "vfx" query parameter is used on the
"[/help?cmd=/timeline|/timeline]" page, it causes the complete
text of forum posts to be displayed.
* Rework the "[/help?cmd=grep|fossil grep]" command to be more useful.
* Expose the [/help?cmd=redirect-to-https|redirect-to-https]
setting to the [/help?cmd=settings|settings] command.
* Improve support for CGI on IIS web servers.
* The [./serverext.wiki|/ext page] can now render index files,
in the same way as the embedded docs.
* Most commands now support the Unix-conventional "<tt>--</tt>"
flag to treat all following arguments as filenames
instead of flags.
* Added the [/help?cmd=mimetypes|mimetypes config setting]
(versionable) to enable mimetype overrides and custom definitions.
* Add an option on the /Admin/Timeline setup page to set a default
timeline style other than "Modern".
* In [./embeddeddoc.wiki|embedded documentation], hyperlink URLs
of the form "/doc/$CURRENT/..." the "$CURRENT" text is translated
into the check-in hash for the document currently being viewed.
* Added the [/help?cmd=/phantoms|/phantoms] webpage that shows all
phantom artifacts.
* Enhancements to phantom processing to try to reduce
bandwidth-using chatter about phantoms on the sync protocol.
* Security: Fossil now assumes that the schema of every
database it opens has been tampered with by an adversary and takes
extra precautions to ensure that such tampering is harmless.
* Security: Fossil now puts the Content-Security-Policy in the
HTTP reply header, in addition to also leaving it in the
HTML <head> section, so that it is always available, even
if a custom skin overrides the HTML <head> and omits
the CSP in the process.
* Output of the [/help?cmd=diff|fossil diff -y] command automatically
adjusts according to the terminal width.
* The Content-Security-Policy is now set using the
[/help?cmd=default-csp|default-csp setting].
* Merge conflicts caused via the [/help?cmd=merge|merge] and
[/help?cmd=update|update] commands no longer leave temporary
files behind unless the new <tt>--keep-merge-files</tt> flag
is used.
* The [/help?cmd=/artifact_stats|/artifact_stats page] is now accessible
to all users if the new "artifact_stats_enable" setting is turned
on. There is a new checkbox under the /Admin/Access menu to turn
that capability on and off.
* Add the [/help?cmd=tls-config|fossil tls-config] command for viewing
the TLS configuration and the list of SSL Cert exceptions.
* Captchas all include a button to read the captcha using an audio
file, so that they can be completed by the visually impaired.
* Stop using the IP address as part of the login cookie.
* Bug fix: fix the SSL cert validation logic so that if an exception
is allowed for particular site, the exception expires as soon as the
cert changes values.
* Bug fix: the FTS search into for forum posts is now kept up-to-date
correctly.
* Bug fix: the "fossil git export" command is now working on Windows
* Bug fix: display Technote items on the timeline correctly
* Bug fix: fix the capability summary matrix of the Security Audit
page so that it does not add "anonymous" capabilities to the
"nobody" user.
* Update internal Unicode character tables, used in regular expression
handling, from version 12.1 to 13.
* Many documentation enhancements.
* Many minor enhancements to existing features.
<h2 id='v2_10'>Changes for Version 2.10 (2019-10-04)</h2>
* (2.10.2): backport security fixes from 2.12.1
* (2.10.1): backport security fix for the "fossil git export" command.
* Added support for [./serverext.wiki|CGI-based Server Extensions].
* Added the [/help?cmd=repolist-skin|repolist-skin] setting used to
add style to repository list pages.
* Enhance the hierarchical display of Forum threads to do less
indentation and to provide links back to the previous message
in the thread. Provide sequential numbers for all messages in
a forum thread.
* Add support for fenced code blocks and improved hyperlink
processing to the [/md_rules|markdown formatter].
* Add support for hyperlinks to wiki pages in the
[/md_rules|markdown formatter].
* Enhance the [/help?cmd=/stat|/stat] page so that it gives the
option to show a breakdown of forum posts.
* The special check-in name "merge-in:BRANCH" means the source of
the most recent merge-in from the parent branch of BRANCH.
* Add hyperlinks to branch-diffs on the /info page and from
timelines of a branch.
* Add graphical context on the [/help?cmd=/vdiff|/vdiff] page.
* Uppercase query parameters, POST parameters, and cookie names are
converted to all lowercase and entered into the parameter set,
instead of being discarded.
* Change the default [./hashpolicy.wiki|hash policy] to SHA3.
* Timeout [./server/any/cgi.md|CGI requests] after 300 seconds, or
some other value set by the
[./cgi.wiki#timeout|"timeout:" property] in the CGI script.
* The check-in lock interval is reduced from 24 hours to 60 seconds,
though the interval is now configurable using a setting.
An additional check for conflicts is added after interactive
check-in comment entry, to compensate for the reduced lock interval.
* Performance optimizations.
* Many documentation improvements.
<h2 id='v2_9'>Changes for Version 2.9 (2019-07-13)</h2>
* Added the [/help?cmd=git|fossil git export] command and instructions
for [./mirrortogithub.md|creating a GitHub mirror of a Fossil project].
* Improved handling of relative hyperlinks on the
[/help?cmd=/artifact|/artifact] pages for wiki. For example,
hyperlinks and the lizard <img> now work correctly
for both [/artifact/2ff24ab0887cf522] and
[/doc/0d7ac90d575004c2415/www/index.wiki].
* Enhancements to the timeline graph layout, to show more information
with less clutter.
* Added tool-tips to the /timeline graph. On by default but can be
disabled by setting the "Tooltip dwell time" to 0 in the timeline
configuration.
* Copy buttons added to various check-in hash and branch name links.
* Double-clicking on a /timeline graph node now jumps to the /info page
for the check-in. So, repurpose the timestamp hyperlink to show all
activity around that check-in in time.
* Added the [/help?cmd=touch|fossil touch] command, and the --setmtime
option on the [/help?cmd=open|fossil open] and
[/help?cmd=update|fossil update] commands.
* Many documentation enhancements.
* For the "[/help?cmd=update|fossil update]" and
"[/help?cmd=checkout|fossil checkout]" commands, if a
managed file is removed because it is no longer part of the target
check-in and the directory containing the file is empty after the
file is removed and the directory is not the current working
directory and is not on the [/help?cmd=empty-dirs|empty-dirs]
list, then also remove the directory.
* Update internal Unicode character tables, used in regular expression
handling, from version 11.0 to 12.1.
* In "[/help?cmd=regexp|fossil regexp]", "[/help?cmd=grep|fossil grep]"
and the TH1 "regexp" command, the -nocase option now removes multiple
diacritics from the same character (derived from SQLite's
remove_diacritics=2)
* Added the [/help?cmd=/secureraw|/secureraw] page that requires the
complete SHA1 or SHA3 hash, not just a prefix, before it will deliver
content.
* Accept purely numeric ISO8601 date/time strings as long as they
do not conflict with a hash. Example: "20190510134217" instead of
"2019-05-10 13:42:17". This helps keep URLs shorter and less
complicated
* Support both "1)" and "1." for numbered lists in markdown, as
commonmark does.
* The sync and clone HTTP requests omit the extra /xfer path element
from the end of the request URI. All servers since 2010 know that
the HTTP request is for a sync or clone from the mimetype so the
extra path element is not needed.
* If an automatic sync gets a permanent redirect request, then update
the saved remote URL to the new address.
* Temporary filenames (for example used for external "diff" commands)
try to preserve the suffix of the original file.
* Added the [/help?cmd=/thisdayinhistory|/thisdayinhistory] web page.
* Enhanced parsing of [/help?cmd=/timeline|/timeline] query parameters
"ymd=", "ym=", and "yw=". All arguments are option (in which case they
default to the current time) and all accept ISO8601 date/times without
punctuation.
* Automatically disapprove pending moderation requests for a user when
that user is deleted. This helps in dealing with spam-bots.
* Improvements to the "Capability Summary" section in the
[/help?cmd=/secaudit0|Security Audit] web-page.
* Use new "ci-lock" and "ci-lock-failed" pragmas in the
[./sync.wiki|sync protocol] to try to prevent accident forks
caused by concurrent commits when operating in auto-sync mode.
* Fix a bug ([https://fossil-scm.org/forum/forumpost/c51b9a1169|details])
that can cause repository databases to be overwritten with debugging
output, thus corrupting the repository. This is only a factor when
CGI debugging is enabled, and even then is a rare occurrence, but it is
obviously an important fix.
<h2 id='v2_8'>Changes for Version 2.8 (2019-02-20)</h2>
* Show cherry-pick merges as dotted lines on the timeline graph.
→ The "fossil rebuild" command must be run to create and
populate the new "cherrypick" table in the repository in order
for this feature to operate.
* Add the ability to associate branches, check-ins, and tags with
specially-named Wiki pages. This gives the ability to better
document branches and tags, and provide more documentation on
check-ins beyond the check-in comment. The associated Wiki is
automatically displayed on /info pages for check-ins, and on
/timeline?r=BRANCH and /timeline?t=TAG pages for branches and
tags. This feature is on by default, but can be disabled in on
the Admin/Wiki page.
* Enhance the repository list page (shown for example by
"fossil all ui") so that it shows the name and last check-in
time for each project. The implementation of the repository
list page is now broken out into a separate source file (repolist.c).
* Allow users with Forum Supervisor permission ('6') to add Forum
Write Trusted permission ('4') to users as they are approving a
forum post by that user.
* When running a bisect, report the number of check-ins still in
the search range and the estimated number of bisect steps remaining.
Do this at each step of the bisect.
* Provide a permanent link to a bisect timeline using the bid= query
parameter.
* Make the chronological forum display feature available to all users,
and make it the default format on mobile devices.
* Break out Wiki setup into a separate /setup_wiki page, accessible
on the standard menus through Admin/Wiki.
* Add "Next" and "Previous" buttons on the /wdiff page, allowing
the user to step through the versions of a wiki page.
* Improve the display of the /whistory page.
* Omit the "HH:MM" timestamps on timeline graphs on narrow-screen
devices, to improve horizontal space uses. This helps make Fossil
more mobile-friendly.
* Enhance /wcontent to show a sortable list of Wiki pages together
with the number of revisions and the most recent change time for
each page.
* Hyperlinks to Wiki pages on the /timeline go to the specific
version of the Wiki page named in the timeline, not to the latest
version.
* Enhancements to the "amend", "tag", and "reparent" commands, including
adding options --override-date, --override-user, and --dry-run.
* Add the global --comment-format command-line option and the
comment-format setting to control the display of the command-line
timeline.
* Change the "fossil reparent" command so that it only works from
within an active checkout.
* On the /setup_ucap_list, show administrators how many users have
each capability. The counts are a hyperlink to the /setup_ulist
page showing the subset of users that have that capability.
* Provide the ability to redirect all HTTP pages to HTTPS. Formerly
one could cause this to occur for the /login page only. That option
still exists, but the redirect can now also be done for all pages.
* "Compress" the built-in javascript by omitting comments and
leading and trailing whitespace.
* Detect when the repository used by a checkout is swapped out for
a clone that uses different RID values, and make appropriate adjustments
to the checkout database to avoid any problems.

backoffice feature.
* Update the built-in SQLite to version 3.27.1.
* Various other small enhancements to webpages and documentation.
<h2 id='v2_7'>Changes for Version 2.7 (2018-09-22)</h2>
* Add the [./alerts.md|email alerts] feature for commits, ticket
changes, wiki changes, forum posts, and announcements. This is
still a work in progress. It is functional, but it is not as easy to
setup and use as it ought to be.
* Add the [./forum.wiki|discussion forum] feature.
* Add new user capabilities letters needed to support alerts and forum.
Formerly, user capabilities were letters from [a-z], but with the
enhancements, the supply of lower case letters was exhausted.
User capabilities are now letters in [a-zA-Z0-9].
* The built-in skins are now responsive, providing better layout on
small screens, including mobile devices.
* The default skin now includes a hamburger menu that is generated
by the [/sitemap] page.
* All of the built-in skins now use a
[https://en.wikipedia.org/wiki/Content_Security_Policy|Content Security Policy (CSP)]
to help prevent cross-site injection and forgery attacks. There are no known
vulnerabilities in Fossil. The added CSP does not fix anything; it merely adds
another layer of defense.
* The [/sitemap] and other list pages show as multiple columns if
the viewing window is wide enough.
* There is an optional "js" file for each skin that can be used to
hold javascript. This file can be loaded by reference or can be

receiving email directly via SMTP, but this feature is not yet
complete or ready for production use.
* The `mv-rm-files` setting is now compiled into Fossil in the
default Fossil configuration; no longer must you say
<tt>./configure --with-legacy-mv-rm</tt> to make it available. The
setting remains disabled by default, however, so you must still say
<tt>fossil set mv-rm-files 1</tt> to enable it on each repository
where you want hard <tt>mv/rm</tt> behavior.
<h2 id='v2_6'>Changes for Version 2.6 (2018-05-04)</h2>
* Fix a bug that was causing crashes while trying to clone the TCL
repository. This fix is the main reason for the current release.
* Added the new "Classic" timeline viewing mode. "Classic" is the
same as "Verbose" in the previous release. The "Verbose" mode is
now like "Compact" except the extra check-in details are shown by
default.
* Add support for ETags:, Last-Modified:, and If-Modified-Since:
cache control mechanisms.
* Enhance the [/help?cmd=/tarball|/tarball],
[/help?cmd=/zip|/zip], and
[/help?cmd=/sqlar|/sqlar] pages so that the checkin
name to be downloaded can be expressed as part of the URI,
and without the need for query parameters.
* On the [/help?cmd=/timeline|/timeline] webpage, add the days=N
query parameter and enhance the ymd=DATE and yw=DATE query parameters
to accept 'now' as an argument to show the latest day or week.
* In the web page that comes up in response to the
[/help?cmd=all|fossil all ui] command, show the last modification
time for each repository, and allow click-to-sort on the modification
time column.
* In the tarball cache replacement algorithm, give extra weight to
tarballs that have been accessed more than once.
* Additional defenses against web-based attacks. There have not been
any known vulnerabilities. We are just being paranoid.
* Update the built-in SQLite to an alpha version of 3.24.0.
<h2 id='v2_5'>Changes for Version 2.5 (2018-02-07)</h2>

Especially: Added separate "Modern", "Compact", "Verbose", and
"Columnar" view options on timelines.
* Common display settings (such as the "view" option and the number
of rows in a timeline) are held in a cookie and thus persist
across multiple pages.
* Rework the skin editing process so that changes are implemented
on one of nine /draft pages, evaluated, then merged back to the
default.
* Added the [https://fossil-scm.org/skins/ardoise/timeline|Ardoise]
skin.
* Fix the "fossil server" command on Unix to be much more responsive
to multiple simultaneous web requests.

script files. This is a step along the
road toward supporting a strict Content Security Policy. More work
is to be done.

system call in OpenBSD. More work is to be done.
<h2 id='v2_4'>Changes for Version 2.4 (2017-11-03)</h2>
* New feature: URL Aliases. URL Aliases allow an administrator
to define their own URLs on the web interface that are rewritten to
built-in URLs with specific parameters. Create and configure URL Aliases
using the /Setup/URL_Aliases menu option in the web interface.
* Add tech-note search capability.
* Add the -r|--revision and -o|--origin options to the
[/help?cmd=annotate|annotate] command.
* Add the origin= query parameter to the [/help?cmd=/annotate|/annotate]
webpage.
* The [/help?cmd=annotate|fossil annotate] command and the
[/help?cmd=/annotate|/annotate] web page go backwards in time as far
as can be computed in 30 milliseconds by default, rather than stopping
after 20 steps. The new limit= query parameter or the --limit command-line
option can be used to alter this timeout.
* Provide separate [/help#settings|on-line help screens for each setting].
* Back out support for the --no-dir-symlinks option
* Remove support from the legacy configuration sync protocol. The only
way now to do a configuration push or pull is to use the new protocol that
was added in 2011.
* Add the from= and to= query parameters to [/help?cmd=/fdiff|/fdiff]
in order to get a diff of two files in the same check-in.
* Fix the "ssh://" protocol to prevent an attack whereby the attacker convinces
a victim to run a "clone" with a dodgy URL and thereby gains access to their
system.
* Provide a checkbox that will temporarily disable all ad-units.
* Improvements to the [/help?cmd=/stat|/stat] page
* Various new hyperlinks to the [/help?cmd=/bloblist|/bloblist]
and [/help?cmd=/bigbloblist|/bigbloblist] pages.

* Correct [/help?cmd=/zip|/zip], [/help?cmd=/tarball|/tarball],
[/help?cmd=zip|zip], and [/help?cmd=tarball|tarball] pages and commands to
honor the versioned manifest setting when outside of an open checkout
directory.

* (Internal:) Add the ability to include resources as separate files in the
source tree that are converted into constant byte arrays in the compiled
binary. Use this feature to store the Tk script that implements the --tk
diff option in a separate file for easier editing.
* (Internal:) Implement a system of compile-time checks to help ensure
the correctness of printf-style formatting strings.
* Fix CVE-2014-3566, also known as the POODLE SSL 3.0 vulnerability.
* Numerous documentation fixes and improvements.
* Other obscure and minor bug fixes - see the timeline for details.
<h2 id='v1_29'>Changes For Version 1.29 (2014-06-12)</h2>
* Add the ability to display content, diffs and annotations for UTF16
text files in the web interface.
* Add the "SaveAs..." and "Invert" buttons
to the graphical diff display that results
from using the --tk option with the [/help/diff | fossil diff] command.
* The [/reports] page now requires Read ("o") permissions. The "byweek"
report now properly propagates the selected year through the event type
filter links.
* The [/help/info | info command] now shows leaf status of the checkout.
* Add support for tunneling https through a http proxy (Ticket [e854101c4f]).
* Add option --empty to the "[/help?cmd=open | fossil open]" command.
* Enhanced [/help?cmd=/fileage|the fileage page] to support a glob parameter.
* Add -w|--ignore-all-space and -Z|--ignore-trailing-space options to
[/help?cmd=annotate|fossil annotate], [/help?cmd=blame|fossil blame],
[/help?cmd=diff|fossil (g)diff], [/help?cmd=stash|fossil stash diff].
* Add --strip-trailing-cr option to [/help?cmd=diff|fossil (g)diff] and
[/help?cmd=stash|fossil stash diff].
* Add button "Ignore Whitespace" to /annotate, /blame, /ci, /fdiff
and /vdiff UI pages.
* Enhance [/reports?view=byweekday|/reports] with a "byweekday" view.
* Enhance the [/help?cmd=cat|fossil cat] command so that it works outside
of a checkout when using the -R command-line option.
* Use full-length SHA1 hashes, not abbreviations, in most hyperlinks.
* Correctly render the <title> markup on wiki pages in the
[/help?cmd=/artifact|/artifact] webpage.
* Enhance the [/help?cmd=whatis|fossil whatis] command to report on attachments
and cluster artifacts. Added the [/help?cmd=test-whatis-all] command for
testing purposes.
* Add support for HTTP Basic Authentication on [/help?cmd=clone|clone] and
[/help?cmd=sync|sync].
* Fix the [/help?cmd=stash|stash] so that it remembers added files and re-adds
them when the stash is applied.
* Fix the server so that it avoids writing to the database (and thus avoids
database locking issues) on a
[/help?cmd=pull|pull] or [/help?cmd=clone|clone].
* Add support for [./server.wiki#loadmgmt|server load management] using both
a cache of expensive pages (the [/help?cmd=cache|fossil cache] command)
and by rejecting expensive page requests when the server load average is too
high.
* Add the [/help?cmd=praise|fossil praise] command as an alias for
[/help?cmd=blame|fossil blame] for subversion compatibility.
* Enhance the [/help?cmd=test-diff|fossil test-diff] command with -y or --tk
options so that it shows both filenames above their respective columns in
the side-by-side diff output.
* Issue a warning if a [/help?cmd=add|fossil add] command tries to add a file
that matches the ignore-glob.
* Add option -W|--width to "[/help?cmd=stash|fossil stash ls]"
and "[/help?cmd=leaves|fossil leaves]" commands.
* Enhance support for running as the root user. Now works on Haiku.
* Added the <tt>-empty</tt> option to [/help?cmd=new|fossil new], which
causes it to not create an initial empty commit. The first commit after
checking out a repo created this way will become the initial commit.
* Enhance sync operations by committing each round-trip to minimize number
of retransmits when autosync fails. Include option for
[/help?cmd=update| fossil update] and [/help?cmd=merge| fossil merge] to
continue even if missing content.
* Minor portability fixes for platforms where the char type is unsigned
by default.
<h2>Changes For Version 1.28 (2014-01-27)</h2>
* Enhance [/help?cmd=/reports | /reports] to support event type filtering.
* When cloning a repository, the user name passed via the URL (if any)
is now used as the default local admin user's name.
* Enhance the SSH transport mechanism so that it runs a single instance of
the "fossil" executable on the remote side, obviating the need for a shell
on the remote side. Some users may need to add the "?fossil=/path/to/fossil"
query parameter to "ssh:" URIs if their fossil binary is not in a standard
place.
* Add the "[/help?cmd=blame | fossil blame]" command that works just like
"fossil annotate" but uses a different output format that includes the
user who made each change and omits line numbers.
* Add the "Tarball and ZIP-archive Prefix" configuration parameter under
Admin/Configuration.
* Fix CGI processing so that it works on web servers that do not
supply REQUEST_URI.
* Add options --dirsonly, --emptydirs, and --allckouts to the
"[/help?cmd=clean | fossil clean]" command.
* Ten-fold performance improvement in large "fossil blame" or
"fossil annotate" commands.
* Add option -W|--width and --offset to "[/help?cmd=timeline | fossil timeline]"
and "[/help?cmd=finfo | fossil finfo]" commands.
* Option -n|--limit of "[/help?cmd=timeline | fossil timeline]" now
specifies the number of entries, just like all other commands which
have the -n|--limit option. The various timeline-related functions
now output "--- ?? limit (??) reached ---" at the end whenever
appropriate. Use "-n 0" if no limit is desired.
* Fix handling of password embedded in Fossil URL.
* New <tt>--once</tt> option to [/help?cmd=clone | fossil clone] command
which does not store the URL or password when cloning.
* Modify [/help?cmd=ui | fossil ui] to respect "default user" in an open
repository.
* Fossil now hides check-ins that have the "hidden" tag in timeline webpages.
* Enhance <tt>/ci_edit</tt> page to add the "hidden" tag to check-ins.
* Advanced possibilities for commit and ticket change notifications over
http using TH1 scripting.
* Add --sha1sum and --integrate options
to the "[/help?cmd=commit | fossil commit]" command.
* Add the "clean" and "extra" subcommands to the
"[/help?cmd=all | fossil all]" command
* Add the --whatif option to "[/help?cmd=clean|fossil clean]" that works the
same as "--dry-run",
so that the name does not collide with the --dry-run option of "fossil all".
* Provide a configuration option to show dates on the web timeline
as "YYMMMDD HH:MM"
* Add an option to the "stats" webpage that allows an administrator to see
the current repository schema.
* Enhancements to the "[/help?cmd=/vdiff|/vdiff]" webpage for more difference
display options.
* Added the "[/tree?ci=trunk&expand | /tree]" webpage as an alternative
to "/dir" and make it the default way of showing file lists.
* Send gzipped HTTP responses to clients that support it.
<h2>Changes For Version 1.27 (2013-09-11)</h2>
* Enhance the [/help?cmd=changes | fossil changes],
[/help?cmd=clean | fossil clean], [/help?cmd=extras | fossil extras],
[/help?cmd=ls | fossil ls] and [/help?cmd=status | fossil status] commands
to restrict operation to files and directories named on the command-line.
* New --integrate option to [/help?cmd=merge | fossil merge], which
automatically closes the merged branch when committing.
* Renamed <tt>/stats_report</tt> page to [/reports]. Graph width is now
relative, not absolute.
* Added <tt>yw=YYYY-WW</tt> (year-week) filter to timeline to limit the results
to a specific year and calendar week number, e.g. [/timeline?yw=2013-01].
* Updates to SQLite to prevent opening a repository file using file descriptors
1 or 2 on Unix. This fixes a bug under which an assertion failure could
overwrite part of a repository database file, corrupting it.
* Added support for unlimited line lengths in side-by-side diffs.
* New --close option to [/help?cmd=commit | fossil commit], which
immediately closes the branch being committed.
* Added <tt>chart</tt> option to [/help?cmd=bisect | fossil bisect].
* Improvements to the "human or bot?" determination.
* Reports errors about missing CGI-standard environment variables for HTTP
servers which do not support them.
* Minor improvements to sync support on Windows.
* Added <tt>--scgi</tt> option to [/help?cmd=server | fossil server].
* Internal improvements to the sync process.
* The internals of the JSON API are now MIT-licensed, so downstream
users/packagers are no longer affected by the "do no evil" license
clause.
<h2>Changes For Version 1.26 (2013-06-18)</h2>
* The argument to the --port option for the [/help?cmd=ui | fossil ui] and
[/help?cmd=server | fossil server] commands can take an IP address in addition
to the port number, causing Fossil to bind to just that one IP address.
* After prompting for a password, also ask if that password should be
remembered.
* Performance improvements to the diff engine.
* Fix the side-by-side diff engine to work better with multi-byte Unicode text.
* Color-coding in the web-based annotation (blame) display. Fix the annotation
engine so that it is no longer confused by time-warps.
* The markdown formatter is now available by default and can be used for
tickets, wiki, and embedded documentation.
* Add subcommands "fossil bisect log" and "fossil bisect status" to the
[/help?cmd=bisect | fossil bisect] command, as well as other bisect enhancements.
* Enhanced defenses that prevent spiders from using excessive CPU and bandwidth.
* Consistent use of the -n or --dry-run command line options.
* Win32: Fossil now understands Cygwin paths containing one or more of
the characters <nowiki>"*:<>?|</nowiki>. Those are normally forbidden in
win32. This means that the win32 fossil.exe is better usable in a Cygwin
environment. See
[http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars].
* Cygwin: Fossil now understands win32 absolute paths starting with a drive
letter everywhere. The default value of the "case-sensitive" setting is
now FALSE, except when case-sensitivity is enabled in the Windows kernel.
See
[http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-casesensitive]
* Enhancements to /timeline.rss, adding more flags for filtering
results, including the ability to subscribe to changes made
to individual tickets. For example: [/timeline.rss?y=t&tkt=12fceeec82].
* Improved handling of the differences between case-sensitive and
case-insensitive filesystems.
* JSON API: added the 'status' command to report local checkout status.
* Fixes to the <tt>--args</tt> support and documented this feature in the help.
* Added [/stats_report] page.
* Added <tt>ym=YYYY-MM</tt> filter to the [/timeline?ym=2013-06].
* Fixed: <tt>config reset</tt> now re-installs default ticket report format.
* <tt>ssh://</tt> and <tt>file://</tt> protocols now ignore proxy settings.
* Added [/hash-color-test] web page.
* Cherry-pick merges are recorded internally (though no yet displayed on the
timeline graph.)
* Bring in the latest versions of SQLite, zlib, and autosetup from upstream.
<h2>Changes For Version 1.25 (2013-02-16)</h2>
* Enhancements to ticket processing. There are now two tables: TICKET and
TICKETCHNG. There is one row in TICKETCHNG for each ticket artifact.
Fields from ticket artifacts go into either or both of TICKET and
TICKETCHNG, whichever contain matching column names. Default ticket
edit and viewing scripts are updated to use TICKETCHNG. The TH1
scripting language is enhanced to support this, including the new
"query" command for doing SQL queries against the repository database.
All changes should be backwards compatible.
* Add the ability to moderate ticket and wiki changes. Unmoderated changes
do not sync and may be deleted by the moderator if found to contain spam
or other objectionable content.
* Add javascript so that clicking on a node of the timeline graph selects
that node. Then clicking on a second node shows a diff between the
two nodes. Clicking on the selected node unselects it.
* Warn of unresolved merge conflicts in "fossil status" and disallow
commits of unresolved conflicts unless the --allow-conflict option
is used.
* Add javascript so that clicking on column headers in a ticket report
sorts by the indicated column.
* Add the "fossil cat" command which is basically an alias for
"fossil finfo -p".
* Hyperlinks with the class "button" are rendered as submenu buttons
on embedded documentation.
* The check-in comment editor on Windows now defaults to NotePad.exe.
* Correctly deal with BOMs in check-in comments. Also attempt to convert
check-in comments to UTF8 from other encodings.
* Allow the deletion of multiple stash entries using multiple arguments
to the "fossil stash rm" command.
* Enhance the "fossil server DIRECTORY" command to serve static content
files contained in DIRECTORY. For security, only files with a
recognized suffix (such as *.html, *.jpg, *.txt, etc) will be delivered
as static content, and *.fossil files are not on the list of recognized
suffixes. There are additional restrictions on the names of the files.
* Allow the "fossil ui" command to specify a directory as long as the
the --notfound option is used.
* Add a configuration option that causes timeline messages to be rendered
as text/x-fossil-plain (which is the same as text/plain except that
hyperlinks inside of <nowiki>[...]</nowiki> are decorated.)
* Only decorate <nowiki>[...]</nowiki> in check-in comments and tickets
if the contented text really is a valid hyperlink target.
* Improvements to the side-by-side diff algorithm, for a more
human-friendly display in some complex cases.
* Added <nowiki>[utime] and [stime]</nowiki> commands to TH1. These
commands can be used for things such as displaying the page rendering
time in the footer.
* Add the ability to pass command-line options of "fossil rebuild" to
"fossil all rebuild".
* Add the --deanalyze option to "fossil rebuild" (and "fossil all rebuild")
* Do not run the graphical merging tool nor leave merge-droppings after a
dry-run merge. Display an improved merge-summary message at the end of
the merge.
* Add options to "fossil commit" to override the various sanity checks.
Options added: --allow-empty, --allow-fork, --allow-older, and
--allow-conflict.
* Optionally require a CAPTCHA (controlled by a setting on the
Admin/Access webpage) when a user who is not logged in tries to
edit wiki, or a ticket, or an attachment.
* Improvements to the "ssh://" sync protocol, to help it move past
noisy motd comments.
* Add the uf=FILE-SHA1-HASH query parameter to the timeline, causing the
timeline to show only check-ins that contain the specific file identified
by FILE-SHA1-HASH. ("uf" stands for "uses file".)
* Enhance the file change annotator so that it follows the file across
name changes.
* Fix the server-side of the sync protocol so that it will not generate
a delta loop when a file changes from its original state, through two
or more intermediate states, and back to the original state, all within
a single sync.
* Show much less output during a sync operation, unless the --verbose
option is used.
* Set the action= attribute of <form> elements using javascript,
as an addition defense against spam-bots.
* Disallow invalid UTF8 characters (such as characters in the surrogate
pair range) in filenames.
* Judge the UserAgent strings issued by the NetSurf webbrowser to be
coming from a human, not from a bot.
* Add the zlib sources to the Fossil source tree (under compat/zlib) and
use those sources when compiling on (Windows) systems that do not have
a zlib library installed by default.
* Prompt the user with the option to convert non-UTF8 files into UTF8
when committing.
* Allow the characters <nowiki>*[]?</nowiki> in filenames.
* Allow the --context option on diff commands to have a value of 0.
* Added the "dbstat" command.
* Enhanced "fossil merge" so that if the VERSION argument is omitted, Fossil
tries to merge any forks of the current branch.
* Improved detection of forks in a commit race.
* Added the --analyze option to "fossil rebuild".
<h2>Changes For Version 1.24 (2012-10-22)</h2>
* Added support for WYSIWYG editing of wiki pages. WYSIWYG is turned off
by default and can be turned on by setting a configuration option.
* Allow style= attribute to occur in HTML markup on wiki pages.
* Added the --tk option to the "fossil diff" and "fossil stash diff"
commands, causing color-coded diff output to be displayed in a Tcl/Tk
GUI window. This option only works if Tcl/Tk is installed on the
host.
* On Windows, make the "gdiff" command default to use WinDiff.exe.
* Update the "fossil stash" command so that it always prompts for a
comment if the -m option is omitted.
* Enhance the timeline webpages so that a=, b=, c=, d=, p=, and dp=
query parameters (and others) can all accept any valid check-in name
(such as branch names or labels) instead of just SHA1 hashes.
* Added the "fossil stash show" command.
* Added the "fileage" webpage with links to this page from the check-in
information page and from the file browser.
* Added --age and -t options to the "fossil ls" command.
* Added the --setmtime option to "fossil update". When used, the mtime
of all managed files is set to the time when the most recent version of
the file was checked in.
* Changed the "vdiff" webpage to show the complete text of files that
were added or removed (the equivalent of using the -N or --newfile
options with the "fossil diff" command-line.)
* Added the --temp option to "fossil clean" and "fossil extra", causing
those commands to only look at temporary files generated by Fossil,
such as merge-conflict reports or aborted check-in messages.
* Enhance the raw page download so that it can guess the mimetype of
attachments based on the filename.
* Change the behavior of the from= and to= query parameters on the
timeline page so that by default the path between the two specified
check-ins avoids merges.
* Add the --baseurl option to "fossil server" and "fossil http" commands,
so that those commands can be used with reverse proxies.
* If unable to determine the command-line user, do not guess. Instead
issue an error message. This helps prevent check-ins from accidentally
occurring under the wrong username.
* Include branch information in the output of file change listings
(the "finfo" webpage).
* Make the simplified view of file history, rather than the full view,
the default.
* In the "fossil configuration" command, allow the "css" option for
synchronizing, importing, or exporting just the CSS file. This makes
it easier to share CSS files across repositories by exporting from
one and importing to another.
* Add the (unsupported) "fossil test-orphans" command.
* Add the --template option to the "fossil init" command, to facilitate
creating new repositories based on a template repository.
* Add the diff-binary setting, which if enabled causes binary files to
be passed to the "gdiff" command for it to deal with, rather than simply
printing a "cannot diff binary files" error.
* Add the --unified option to the "fossil diff" command to force a unified
diff even if the --tk option (which normally implies a side-by-side diff)
is used.
* Present a choice of nearby branches and versions to diff against on the
check-in information page.
* Add the --force option to the "fossil merge" command that will force the
merge to occur even if it would be a no-op. This is sometimes useful for
documentation purposes.
* Add another built-in skin: "Enhanced Default". Other minor tweaks to
the existing skins.
* Add the "urllist" webpage, showing a list of URLs by which a server
instance of Fossil has been accessed. Requires "Administrator" privileges.
A link is on the "Setup" main page.
* Enable dynamic loading of the Tcl runtime for installations that want
to use Tcl as part of their configuration. This reduces the size of
the Fossil binary and allows any version of Tcl 8.4 or later to be used.
* Merge the latest SQLite changes from upstream.
* Lots of minor bug fixes.
<h2>Changes For Version 1.23 (2012-08-08)</h2>
* The default checkout database name is now ".fslckout" instead of
"_FOSSIL_" on Unix. Both names continue to work.
* Added the "fossil all changes" command
* Added the --ckout option to the "fossil all list" command
* Added the "public-pages" glob pattern that can be configured to allow
anonymous users to see embedded documentation on sites where source
code should not be accessible to anonymous users.
* Allow multiple --tag options on the same "fossil commit" command.
* Change the meaning of the --bgcolor option for "fossil commit" to only
change the color for that one commit. The new --branchcolor option
is available to set a persistent background color.
* Add the branch= query parameter to the vdiff page and the --branch option
to the "fossil diff" command.
* Check-in names of the form "root:BRANCH" now refer to the origin of
the branch. Hence to see all changes in a branch, use
"fossil diff --from root:BRANCH --to BRANCH". The --branch option on
the diff command is an alias for the same.
* Add the ability to configure ad-units to be displayed between the menu
bar and the content.
* Add the ability to set a background image as part of server configuration.
* Allow partial commits of cherrypick merges.
* Updates against an uncommitted merge are now a warning, not a fatal error.
* Prompt the user to continue if a check-in comment is unedited.
* Fixes to case sensitivity settings with the /dir webpage.
* Repositories now try to remember the locations of all checkouts and
web-access URLs and display this information with the
"fossil info $REPO" command.
* Improved defense against spiders: The src= attribute of
<a> elements is set using javascript after the page loads.
* Enhanced formatting of the user list page.
* If a file named in "fossil add" is missing, that is now a warning instead
of a fatal error.
* Fix side-by-side diff so that it displays correctly with
multi-byte UTF8 characters.
* Performance improvements in the diff logic.
* Other performance tweaks and documentation updates.
<h2>Changes For Version 1.22 (2012-03-17)</h2>
* Greatly improved "diff" processing including the new --brief option,
partial line matching, colorized in-line diffs, and better performance.
* Promote "allow-symlinks" to a versionable setting
* Harden the CGI processing logic against DOS attacks
* Add the ability to run TH1 scripts after sync requests
* Store the repository name in _FOSSIL_ as it is type in the "open" command,
possibly as a relative pathname.
* Make ".fslckout" the alternative name for the "_FOSSIL_" file.
* Change the "ssh:" transfer method to allow all access regardless of
user permission.
* Improvements to the timeline messages associated with tag changes.
(Requires a "[/help/rebuild | fossil rebuild]" to take effect.)
* Various additions and fixes for the JSON API.
* Improved merge-with-rename handling.
* --cherrypick merges use their origin's commit message by default.
* Added support for multiple concurrent logins per user.
* Update to use SQLite version 3.7.11.
* Various minor bug fixes.
<h2>Changes For Version 1.21 (2011-12-13)</h2>
* Added side-by-side diffs in the command-line interface
* Automatically enable hyperlinks if the UserAgent string in the
HTTP header suggests that the requestor is a human and not a bot.
* Show only commonly used commands with "fossil help". Use
"fossil help --all" to see the complete list now.
* Improvements to the "stash" command: (1) Stash all files, not just
those below the working directory. (2) Add the --detail option to
"list". (3) Confirm before "drop --all". (4) Add the "help"
subcommand.
* Add an Admin/Access setting to change the number of octets of the
IP address that are saved in login cookies - allowing this setting
to be changed to zero
* Promote the "test-md5sum" command to "md5sum".
* Added the "whatis" command.
* Stop showing the server-code in status outputs - it is no longer used
for anything.
* Added a compile-time option (--with-tcl) to build in full Tcl scripting
support via integration with TH1.
* Merged the JSON branch into trunk. Disabled by default. Enabled
by a compile-time option. Probably it will be enabled by default
in some future release.
* Update to use SQLite version 3.7.9 plus the alignment fix for Sparc.
align

* Added --args FILENAME global CLI argument to import arbitrary
CLI arguments from a file (e.g. long file lists). [e080560378]
* Fixed significant memory leak in annotation of files with long
histories.[9929bab702]
* Added warnings when a merge operation overwrites local copies
(UNDO is available, but previously this condition normally went
silently unnoticed). [39f979b08c]
* Improved performance when adding many files. [a369dc7721]
* Improve merges which contain many file renames. [0b93b0f958]
* Added protection against timing attacks. [d4a341b49d]

* Added a ./configure script based on autosetup.
* Added the "[/help/winsrv | fossil winsrv]" command
for creating a Fossil service on Windows systems.
* Added "versionable settings" where settings that affect
the local tree can be stored in versioned files in the
.fossil-settings directory.
* Background colors for branches are chosen automatically if no
color is specified by the user.
* The status, changes and extras commands now show
pathnames relative to the current working directory,
unless overridden by command line options or the
"relative-paths" setting.<br><b>WARNING:</b> This
change will break scripts which rely on the current
output when the current working directory is not the
repository root.
* Added "empty-dirs" versionable setting.
* Added support for client-side SSL certificates with "ssl-identity"
setting and --ssl-identity option.
* Added "ssl-ca-location" setting to specify trusted root

# Fossil Chat
## Introduction
Fossil’s developer chatroom feature provides an
ephemeral discussion venue for insiders. Design goals include:
* **Simple but functional** →
Fossil chat is designed to provide a convenient real-time
communication mechanism for geographically dispersed developers.
Fossil chat is *not* intended as a replacement or competitor for
IRC, Slack, Discord, Telegram, Google Hangouts, etc.
* **Low administration** →
You can activate the chatroom in seconds without having to
mess with configuration files or install new software.
In an existing [server setup](./server/),
simply enable the [C capability](/setup_ucap_list) for users
whom you want to give access to the chatroom.
* **Ephemeral** →
Chat messages do not sync to peer repositories, and they are
automatically deleted after a configurable delay (default: 7 days).
Individual messages or the entire conversation
can be deleted at any time without impacting any other part
of the system.
Fossil chat is designed for use by insiders - people with check-in
privileges or higher. It is not intended as a general-purpose gathering
place for random passers-by on the internet.
Fossil chat seeks to provide a communication venue for discussion
that does *not* become part of the permanent record for the project.
For persistent and durable discussion, use the [Forum](./forum.wiki).
Because the conversation is intended to be ephemeral, the chat messages
are local to a single repository. Chat content does not sync.
## Setup
A Fossil repository must be functioning as a [server](./server/) in order
for chat to work.
To activate chat, simply add the [C capability](/setup_ucap_list)
to every user who is authorized to participate. Anyone who can read chat
can also post to chat.
Setup ("s") and Admin ("a") users always have access to chat, without needing
the "C" capability. A common configuration is to add the "C" capability
to "Developer" so that any individual user who has the "v" capability will
also have access to chat.
There are also some settings under /Admin/Chat that control the
behavior of chat, though the default settings are reasonable so in most
cases those settings can be ignored. The settings control things like
the amount of time that chat messages are retained before being purged
from the repository database.
## <a id="usage"></a>Usage
For users with appropriate permissions, simply browse to the
[/chat](/help?cmd=/chat) to start up a chat session. The default
skin includes a "Chat" entry on the menu bar on wide screens for
people with chat privilege. There is also a "Chat" option on
the [Sitemap page](/sitemap), which means that chat will appear
as an option under the hamburger menu for many [skins](./customskin.md).
Chat messages are subject to [Fossil's
full range of Markdown processing](/md_rules). Because chat messages are
stored as-is when they arrive from a client, this change applies
retroactively to messages stored by previous fossil versions.
Files may be sent via chat using the file selection element at the
bottom of the page. If the desktop environment system supports it,
files may be dragged and dropped onto that element. Files are not
automatically sent - selection of a file can be cancelled using the
Cancel button which appears only when a file is selected. When the
Send button is pressed, any pending text is submitted along with the
selected file. Image files sent this way will, by default, appear
inline in messages, but each user may toggle that via the settings
popup menu, such that images instead appear as downloadable links.
Non-image files always appear in messages as download links.
### Deletion of Messages
<div class="sidebar">Message deletion is itself a type of message, which
is why deletions count towards updates in the recent activity list. (It
is counted for the person who performed the deletion, not the author of
the deleted comment.) That can potentially lead to odd corner cases
where a user shows up in the list but has no messages which are
currently visible because they were deleted, or an admin user who has
not posted anything but deleted a message. That is a known minor
cosmetic-only bug with a resolution of "will not fix."</div>
Any user may *locally* delete a given message by clicking on the "tab"
at the top of the message and clicking the button which appears. Such
deletions are local-only, and the messages will reappear if the page
is reloaded. The user who posted a given message, or any Admin users,
may additionally choose to globally delete a message from the chat
record, which deletes it not only from their own browser but also
propagates the removal to all connected clients the next time they
poll for new messages.
### <a id='notifications'></a>Customizing New-message Notification Sounds
By default, the list of new-message notification sounds is limited to
a few built in to the fossil binary. In addition, any
[unversioned files](./unvers.wiki) named `alert-sounds/*.{mp3,wav,ogg}`
will be included in that list. To switch sounds, tap the "settings"
button.
### <a id='connection'></a> Who's Online?
Because the chat app has to be able to work over transient CGI-based
connections, as opposed to a stable socket connection to the server,
real-time tracking of "who's online" is not feasible.
Chat offers an optional feature, toggleable in the settings,
which can list users who have posted messages in the client's current
list of loaded messages. This is not the same thing as tracking who's
online, but it gives an overview of which users have been active most
recently, noting that "lurkers" (people who post no messages) will not
show up in that list, nor does the chat infrastructure have a way to
track and present those. That list can be used to filter messages on a
specific user by tapping on that user's name, tapping a second time to
remove the filter.
### <a id="cli"></a> The `fossil chat` Command
Type [fossil chat](/help?cmd=chat) from within any open check-out
to bring up a chatroom for the project that is in that checkout.
The new chat window will attempt to connect to the default sync
target for that check-out (the server whose URL is shown by the
[fossil remote](/help?cmd=remote) command).
### <a id="robots"></a> Chat Messages From Robots
The [fossil chat send](/help?cmd=chat) can be used by project-specific
robots to send notifications to the chatroom. For example, on the
[SQLite project](https://sqlite.org/) (for which the Fossil chatroom
feature, and indeed all of Fossil, was invented) there are long-running
fuzz servers that sometimes run across obscure problems. Whenever this
happens, a message is sent to the SQLite developers chatroom alerting
them to the problem.
The recommended way to allow robots to send chat messages is to create
a new user on the server for each robot. Give each such robot account
the "C" privilege only. That means that the robot user account will be
able to send chat messages, but not do anything else. Then, in the
program or script that runs the robot, when it wants to send a chat
message, have it run a command like this:
~~~~
fossil chat send --remote https://robot:PASSWORD@project.org/fossil \
--message 'MESSAGE TEXT' --file file-to-attach.txt
~~~~
Substitute the appropriate project URL, robot account
name and password, message text and file attachment, of course.
### <a id="chat-robot"></a> Chat Messages For Timeline Events
If the [chat-timeline-user setting](/help?cmd=chat-timeline-user) is not an
empty string, then any change to the repository that would normally result
in a new timeline entry is announced in the chatroom. The announcement
appears to come from a user whose name is given by the chat-timeline-user
setting.
This mechanism is similar to [email notification](./alerts.md) except that
the notification is sent via chat instead of via email.
## Implementation Details
*You do not need to understand how Fossil chat works in order to use it.
But many developers prefer to know how their tools work.
This section is provided for the benefit of those curious developers.*
The [/chat](/help?cmd=/chat) webpage downloads a small amount of HTML
and a small amount of javascript to run the chat session. The
javascript uses XMLHttpRequest (XHR) to download chat content, post
new content, or delete historical messages. The following web
interfaces are used by the XHR:
* [/chat-poll](/help?name=/chat-poll) →
Downloads chat content as JSON.
Chat messages are numbered sequentially.
The client tells the server the largest chat message it currently
holds, and the server sends back subsequent messages. If there
are no subsequent messages, the /chat-poll page blocks until new
messages are available.
* [/chat-send](/help?name=/chat-send) →
Sends a new chat message to the server.
* [/chat-delete](/help?name=/chat-delete) →
Deletes a chat message.
Fossil chat uses the venerable "hanging GET" or
"[long polling](wikipedia:/wiki/Push_technology#Long_polling)"
technique to receive asynchronous notification of new messages.
This is done because long polling works well with CGI and SCGI,
which are the usual mechanisms for setting up a Fossil server.
More advanced notification techniques such as
[Server-sent events](wikipedia:/wiki/Server-sent_events) and especially
[WebSockets](wikipedia:/wiki/WebSocket) might seem more appropriate for
a chat system, but those technologies are not compatible with CGI.
Downloading of posted files and images uses a separate, non-XHR interface:
* [/chat-download](/help?name=/chat-download) →
Fetches the file content associated with a post (one file per
post, maximum). In the UI, this is accessed via links to uploaded
files and via inlined image tags.
Chat messages are stored on the server-side in the CHAT table of
the repository.
~~~
CREATE TABLE repository.chat(
msgid INTEGER PRIMARY KEY AUTOINCREMENT,
mtime JULIANDAY, -- Time for this entry - Julianday Zulu
lmtime TEXT, -- Client YYYY-MM-DDZHH:MM:SS when message originally sent
xfrom TEXT, -- Login of the sender
xmsg TEXT, -- Raw, unformatted text of the message
fname TEXT, -- Filename of the uploaded file, or NULL
fmime TEXT, -- MIMEType of the upload file, or NULL
mdel INT, -- msgid of another message to delete
file BLOB -- Text of the uploaded file, or NULL
);
~~~
The CHAT table is not cross-linked with any other tables in the repository
schema. An administrator can "DROP TABLE chat;" at any time, without
harm (apart from deleting all chat history, of course). The CHAT table
is dropped when running [fossil scrub --verily](/help?cmd=scrub).
On the server-side, message text is stored exactly as entered by the
users. The /chat-poll page queries the CHAT table and constructs a
JSON reply described in the [/chat-poll
documentation](/help?cmd=/chat-poll). The message text is translated
into HTML before being converted to JSON so that the text can be
safely added to the display using assignment to `innerHTML`. Though
`innerHTML` assignment is generally considered unsafe, it is only so
with untrusted content from untrusted sources. The chat content goes
through sanitization steps which eliminate any potential security
vulnerabilities of assigning that content to `innerHTML`.

<title>Check-in Checklist</title>
<h2><u>Always</u> run the following checklist prior to <u>every</u>
check-in or commit to the Fossil repository:</h2>
Before every check-in:
0. <b>fossil user default</b> → your username is correct.
1. <b>fossil diff</b> →
<ol type="a">
<li> No stray changes
<li> All changes comply with the license
<li> All inputs are scrubbed before use
<li> No injection attacks via %s formats
</ol>
2. <b>fossil extra</b> → no unmanaged files need to be added.
3. The check-in will go onto the desired branch.
→ Check-ins to trunk normally require approval from
the lead programmer (drh).
4. auto-sync is on, or the system clock is verified
5. If sources files have been added or removed, ensure all makefiles
and configure scripts have been updated accordingly.
Before every check-in to <b>trunk</b>:
6. No compiler warnings on the development machine.
7. The fossil executable that results from a build actually works.
<hr>
<h2>Commentary</h2>
Before you go ahead and push content back to the servers, make sure
that the username you are using by default matches your username
within the project. Also remember to enable the localauth setting
if you intend to make changes via a locally served web UI.
Item 1 is the most important step. Consider using <b>gdiff</b>
instead of <b>diff</b> if you have a graphical differ configured. Or
use the command-line option <b>--tk</b>. Also consider the <b>-v</b>
command-line option to show the complete text of newly added files.
The recommended command for completing checklist item 1 is:
<b>fossil diff --tk -v</b>
Look carefully at every changed line in item 1.
Make sure that you are not about to commit unrelated changes.
If there are two or more unrelated changes present, consider
breaking up the commit into two or more separate commits.
Always make 100% sure that all changes are compatible with the
BSD license, that you have the authority to commit the code in accordance
with the [/doc/trunk/www/copyright-release.html | CLA] that you have
signed and have on file, and that
no NDAs, copyrights, patents, or trademarks are infringed by the check-in.
Also check very carefully to make sure that
you are not introducing security vulnerabilities. Pay particular attention
to the possibility of SQL or HTML injection attacks.
Item 2 verifies that you have not added source files but failed to
do the necessary "<b>fossil add</b>" to manage them. If you commit
without bringing the new file under source control, the check-in will
be broken. That, in turn, can cause complications far in the future
when we are bisecting for a bug.
For item 3, Run "<b>fossil status</b>" or the equivalent to
make sure your changes are going into the branch you think they are.
Also double-check the branch name when entering change comments.
Never check into trunk unless you are expressly authorized to do so.
For Item 4, if you are on-network, make sure auto-sync is enabled. This
will minimize the risk of an unintended fork. It will also give you a
warning if you system clock is set incorrectly. If you are off-network,
make sure that your system clock is correct or at least close to correct
so that your check-in does not appear out-of-sequence on timelines.
On-network commits are preferred, especially for trunk commits.
Items 6 and 7 help to ensure that check-ins on the trunk always work.
Knowing that the trunk always works makes bisecting much easier. Items
6 and 7 are recommended for all check-ins, even those that are on a branch.
But they are especially important for trunk check-ins. We desire that
all trunk check-ins work at all times. Any experimental, unstable, or
questionable changes should go on a branch and be merged into trunk after
further testing.

</ul>
</div>
Many Fossil [/help|commands] and [./webui.wiki | web interface] URLs accept
check-in names as an argument. For example, the "[/help/info|info]" command
accepts an optional check-in name to identify the specific check-in
about which information is desired:
<pre style="white-space: pre-wrap">
fossil info <i>checkin-name</i>
</pre>
You are perhaps reading this page from the following URL:
<verbatim>
https://fossil-scm.org/home/doc/trunk/www/checkin_names.wiki
</verbatim>
This is an example of an [./embeddeddoc.wiki | embedded documentation]
page URL. The "trunk" element of the pathname is a
[./glossary.md#check-in | check-in] name that
determines which version of the documentation to display.
Fossil provides a variety of ways to specify a check-in. This
document describes the various methods.
<h2 id="canonical">Canonical Check-in Name</h2>
The canonical name of a check-in is the hash of its
[./fileformat.wiki#manifest | manifest] expressed as a
[./hashes.md | long lowercase hexadecimal number]. For example:
<pre>
fossil info e5a734a19a9826973e1d073b49dc2a16aa2308f9
</pre>
The full 40 or 64 character hash is unwieldy to remember and type, though,
so Fossil also accepts a unique prefix of the hash, using any combination
of upper and lower case letters, as long as the prefix is at least 4
characters long. Hence the following commands all
accomplish the same thing as the above:
<pre>
fossil info e5a734a19a9
fossil info E5a734A
fossil info e5a7
</pre>
Fossil uses this feature itself, identifying check-ins by 8 to 16-character
prefixes of the canonical name in places where it doesn't want to chew
up the screen real estate required to display the whole hash.
<h2 id="tags">Tags And Branch Names</h2>
Using a tag or branch name where a check-in name is expected causes
Fossil to choose the most recent check-in with that tag or branch name.
So for example, the most recent check-in that
is tagged with "release" as of this writing is [b98ce23d4fc].
The command:
<pre>
fossil info release
</pre>
…results in the following output:
<pre>
hash: b98ce23d4fc3b734cdc058ee8a67e6dad675ca13 2020-08-20 13:27:04 UTC
parent: 40feec329163103293d98dfcc2d119d1a16b227a 2020-08-20 13:01:51 UTC
tags: release, branch-2.12, version-2.12.1
comment: Version 2.12.1 (user: drh)
</pre>
There are multiple check-ins that are tagged with "release" but
(as of this writing) the [b98ce23d4fc]
check-in is the most recent so it is the one that is selected.
Note that unlike some other version control systems, a "branch" in Fossil
is not anything special: it is simply a sequence of check-ins that
share a common tag, so the same mechanism that resolves tag names
also resolves branch names.
<a id="tagpfx"></a>
Note also that there can — in theory, if rarely in practice — be an ambiguity
between tag names and canonical names. Suppose, for example, you had a
check-in with the canonical name deed28aa99… and you
also happened to have tagged a different check-in with "deed2". If
you use the "deed2" name, does it choose the canonical name or the tag
name? In such cases, you can prefix the tag name with "tag:".
For example:
<pre>
fossil info tag:deed2
</pre>
The "tag:deed2" name will refer to the most recent check-in
tagged with "deed2" rather than the
check-in whose canonical name begins with "deed2".
<h2 id="whole-branches">Whole Branches</h2>
Usually when a branch name is specified, it means the latest check-in on
that branch, but for some commands (ex: [/help/purge|purge]) a branch name
on the argument means the earliest connected check-in on the branch. This
seems confusing when being explained here, but it works out to be intuitive
in practice.
For example, the command "fossil purge XYZ" means to purge the check-in XYZ
and all of its descendants. But when XYZ is in the form of a branch name, one
generally wants to purge the entire branch, not just the last check-in on the
branch. And so for this reason, commands like purge will interpret a branch
name to be the first check-in of the branch rather than the last. If there
are two or more branches with the same name, then these commands will select
the first check-in of the branch that has the most recent check-in. What
happens is that Fossil searches for the most recent check-in with the given
tag, just as it always does. But if that tag is a branch name, it then walks
back down the branch looking for the first check-in of that branch.
Again, this behavior only occurs on a few commands where it make sense.
<h2 id="timestamps">Timestamps</h2>
A timestamp in one of the formats shown below means the most recent
check-in that occurs no later than the timestamp given:
1. <i>YYYY-MM-DD</i>
2. <i>YYYY-MM-DD HH:MM</i>
3. <i>YYYY-MM-DD HH:MM:SS</i>
4. <i>YYYY-MM-DD HH:MM:SS.SSS</i>
5. <i>YYYYMMDD</i>
6. <i>YYYYMMDDHHMM</i>
7. <i>YYYYMMDDHHMMSS</i>
In the second through the fourth forms,
the space between the day and the year can optionally be
replaced by an uppercase <b>T</b>, and the entire timestamp can
optionally be followed by "<b>z</b>" or "<b>Z</b>". In the fourth
form with fractional seconds, any number of digits may follow the
decimal point, though due to precision limits only the first three
digits will be significant. The final three pure-digit forms
without punctuation are only valid if the number they encode is
not also the prefix of an artifact hash.
In its default configuration, Fossil interprets and displays all dates
in Universal Coordinated Time (UTC). This tends to work the best for
distributed projects where participants are scattered around the globe.
But there is an option on the Admin/Timeline page of the web interface to
switch to local time. The "<b>Z</b>" suffix on a timestamp check-in
name is meaningless if Fossil is in the default mode of using UTC for
everything, but if Fossil has been switched to local time mode, then the
"<b>Z</b>" suffix means to interpret that particular timestamp using
UTC instead of local time.
You may prefix a timestamp with the string “date:â€, in which case
processing stops immediately, whether the string is parsed correctly and
refers to anything within the repository or not. The prefix is therefore
useful when the date could be misinterpreted as a tag. For example, a
repo could have release tags like “2020-04-01â€, the date the release was
cut, but you could force Fossil to interpret that string as a date
rather than as a tag by passing “date:2020-04-01â€.
For an example of how timestamps are useful,
consider the homepage for the Fossil website itself:
<pre>
https://fossil-scm.org/home/doc/<b>trunk</b>/www/index.wiki
</pre>
The bold component of that URL is a check-in name. To see the stored content
of the Fossil website repository as of January 1, 2009, one has merely to change
the URL to the following:
<pre>
https://fossil-scm.org/home/doc/<b>2009-01-01</b>/www/index.wiki
</pre>
(Note that this won't roll you back to the <i>skin</i> and other
cosmetic configurations as of that date. It also won't change screens
like the timeline, which has an independent date selector.)
<h2 id="tag-ts">Tag And Timestamp</h2>
A check-in name can also take the form of a tag or branch name followed by
a colon and then a timestamp. The combination means to take the most
recent check-in with the given tag or branch which is not more recent than
the timestamp. So, for example:
<pre>
fossil update trunk:2010-07-01T14:30
</pre>
Would cause Fossil to update the working check-out to be the most recent
check-in on the trunk that is not more recent than 14:30 (UTC) on
July 1, 2010.
<h2 id="root">Root Of A Branch</h2>
A branch name that begins with the "<tt>root:</tt>" prefix refers to the
last check-in on the parent branch prior to the beginning of the branch.
Such a label is useful, for example, in computing all diffs for a single
branch. The following example will show all changes in the hypothetical
branch "xyzzy":
<pre>
fossil diff --from root:xyzzy --to xyzzy
</pre>
<a id="merge-in"></a>
That doesn't do what you might expect after you merge the parent
branch's changes into the child branch: the above command will include
changes made on the parent branch as well.
You can solve this by using the prefix "<tt>merge-in:</tt>" instead of
"<tt>root:</tt>" to tell Fossil to find
the most recent merge-in point for that branch.
The resulting diff will then show only the changes in
the branch itself, omitting
any changes that have already been merged in from the parent branch.
<a id="start"></a>
The prefix "<tt>start:</tt>" gives the first check-in of the named branch.
The prefixes "<tt>root:</tt>", "<tt>start:</tt>", and "<tt>merge-in:</tt>"
can be chained: one can say for example
<pre>
fossil info merge-in:xyzzy:2022-03-01
</pre>
to get information about the most recent merge-in point on the branch
"xyzzy" that happened on or before March 1, 2022.
<h2 id="special">Special Tags</h2>
The tag "tip" means the most recent check-in. The "tip" tag is practically
equivalent to the timestamp "9999-12-31".
This special name works anywhere you can pass a "NAME", such as with
<tt>/info</tt> URLs:
<pre>
http://localhost:8080/info/tip
</pre>
There are several other special names, but they only work from within a
check-out directory because they are relative to the current checked-out
version:
* "current": the current checked-out version
* "next": the youngest child of the current checked-out version
* "previous" or "prev": the primary (non-merge) parent of "current"
Therefore, you can use these names in a <tt>fossil info</tt> command,
but not in an <tt>/info</tt> URL, for example.
For embedded documentation URLs only, there is one more special name,
"ckout". See [./embeddeddoc.wiki#ckout | its coverage elsewhere] for
more details. You cannot currently use "ckout" anywhere other than in
<tt>/doc</tt> URLs.
<h2 id="examples">Additional Examples</h2>
To view the changes in the most recent check-in prior to the version currently
checked out:
<pre>
fossil diff --from previous --to current
</pre>
Suppose you are of the habit of tagging each release with a "release" tag.
Then to see everything that has changed on the trunk since the last release:
<pre>
fossil diff --from release --to trunk
</pre>
<h2 id="order">Resolution Order</h2>
Fossil currently resolves name strings to artifact hashes in the
following order:
# Exact matches on [#special | the special names]
# [#timestamps | Timestamps], with preference to ISO8601 forms
# [#tagpfx | tag:TAGNAME]
# [#root | root:BRANCH]
# [#start | start:BRANCH]
# [#merge-in | merge-in:BRANCH]
# [#tag-ts | TAGNAME:timestamp]
# Full artifact hash or hash prefix.
# Any other type of symbolic name that Fossil extracts from
artifacts.

<title>Child Projects</title>
<h2>Background</h2>
The default behavior of Fossil is to share everything (all check-ins,
tickets, wiki, etc) between all clients and all servers. Such a policy
helps to promote a cohesive design for a cathedral-style project run
by a small cliche of developers - the sort of project for which Fossil
was designed.
But sometimes it is desirable to branch off a side project that does not
sync back to the master but does continue to track changes in the master.
For example, the master project might be an open-source project like
[https://www.sqlite.org/|SQLite] and a team might want to do a proprietary
closed-source enhancement to that master project in a separate repository.
All changes in the master project should flow forward into the derived
project, but care must be taken to prevent proprietary content from the
derived project from leaking back into the master.
<h2>Child Projects</h2>
A scenario such as the above can be accomplished in Fossil by creating
a child project. The child project is able to freely pull from the parent,
but the parent cannot push or pull from the child nor is the child able to
push to the parent. Content flows from parent to child only, and then only
at the request of the child.
<h2>Creating a Child Project</h2>
To create a new child project, first clone the parent. Then make manual
SQL changes to the child repository as follows:
<verbatim>
UPDATE config SET name='parent-project-code' WHERE name='project-code';
UPDATE config SET name='parent-project-name' WHERE name='project-name';
INSERT INTO config(name,value)
VALUES('project-code',lower(hex(randomblob(20))));
INSERT INTO config(name,value)
VALUES('project-name','CHILD-PROJECT-NAME');
</verbatim>
Modify the CHILD-PROJECT-NAME in the last statement to be the name of
the child project, of course.
The repository is now a separate project, independent from its parent.
Clone the new project to the developers as needed.
The child project and the parent project will not normally be able to sync
with one another, since they are now separate projects with distinct
project codes. However, if the
"--from-parent-project" command-line option is provided to the
"[/help?cmd=pull|fossil pull]" command in the child, and the URL of
parent repository is also provided on the command-line, then updates to
the parent project that occurred after the child was created will be added
to the child repository. Thus, by periodically doing a
pull --from-parent-project, the child project is able to stay up to date
with all the latest changes in the parent.

# The Server Chroot Jail
If you run Fossil as root in any mode that [serves data on the
network][srv], and you're running it on Unix or a compatible OS, Fossil
will drop itself into a [`chroot(2)` jail][cj] shortly after starting
up, once it's done everything that requires root access. Most commonly,
you run Fossil as root to allow it to bind to TCP port 80 for HTTP
service, since normal users are restricted to ports 1024 and up on OSes
where this behavior occurs.
Fossil uses the owner of the Fossil repository file as its new user
ID when dropping root privileges.
When this happens, Fossil needs to have all of its dependencies inside
the chroot jail in order to continue work. There are several things you
typically need in order to make things work properly:
* the repository file(s)
* `/dev/null` — create it with `mknod(8)` inside the jail directory
([Linux example][mnl], [OpenBSD example][obsd])
* `/dev/urandom` — ditto
* `/proc` — you might need to mount this virtual filesystem inside the
jail on Linux systems that make use of [Fossil’s server load
shedding feature][fls]
* any shared libraries your `fossil` binary is linked to, unless you
[configured Fossil with `--static`][bld] to avoid it
Fossil does all of this in order to protect the host OS. You can make it
bypass the jail part of this by passing <tt>--nojail</tt> to <tt>fossil server</tt>,
but you cannot make it skip the dropping of root privileges, on purpose.

# Check-Out Workflows
Because Fossil separates the concept of “check-out directory†from
“repository DB file,†it gives you the freedom to choose from several
working styles. Contrast Git, where the two concepts are normally
intermingled in a single working directory, which strongly encourages
the “update in place†working style.
## <a id="mcw"></a> Multiple-Checkout Workflow
With Fossil, it is routine to have multiple check-outs from the same
repository:
fossil clone https://example.com/repo /path/to/repo.fossil
mkdir -p ~/src/my-project/trunk
cd ~/src/my-project/trunk
fossil open /path/to/repo.fossil # implicitly opens “trunkâ€
mkdir ../release
cd ../release
fossil open /path/to/repo.fossil release
mkdir ../my-other-branch
cd ../my-other-branch
fossil open /path/to/repo.fossil my-other-branch
mkdir ../scratch
cd ../scratch
fossil open /path/to/repo.fossil abcd1234
mkdir ../test
cd ../test
fossil open /path/to/repo.fossil 2019-04-01
Now you have five separate check-out directories: one each for:
* trunk
* the latest tagged public release
* an alternate branch you’re working on
* a “scratch†directory for experiments you don’t want to do in the
other check-out directories; and
* a “test†directory where you’re currently running a long-running
test to evaluate a user bug report against the version as of last
April Fool’s Day.
Each check-out operates independently of the others.
This multiple-checkouts working style is especially useful when Fossil stores source code in programming languages
where there is a “build†step that transforms source files into files
you actually run or distribute. Contrast a switch-in-place workflow,
where you have to rebuild all outputs from the source files
that differ between those versions whenever you switch versions. In the above model,
you switch versions with a “`cd`†command instead, so that you only have
to rebuild outputs from files you yourself change.
This style is also useful when a check-out directory may be tied up with
some long-running process, as with the “test†example above, where you
might need to run an hours-long brute-force replication script to tickle
a [Heisenbug][hb], forcing it to show itself. While that runs, you can
open a new terminal tab, “`cd ../trunk`â€, and get back
to work.
[hb]: https://en.wikipedia.org/wiki/Heisenbug
## <a id="scw"></a> Single-Checkout Workflows
Nevertheless, it is possible to work in a more typical Git sort of
style, switching between versions in a single check-out directory.
#### <a id="idiomatic"></a> The Idiomatic Fossil Way
The most idiomatic way is as follows:
fossil clone https://example.com/repo /path/to/repo.fossil
mkdir work-dir
cd work-dir
fossil open /path/to/repo.fossil
...work on trunk...
fossil update my-other-branch
...work on your other branch in the same directory...
Basically, you replace the `cd` commands in the multiple checkouts
workflow above with `fossil up` commands.
#### <a id="open"></a> Opening a Repository by URI
You can instead open the repo’s URI directly:
mkdir work-dir
cd work-dir
fossil open https://example.com/repo
Now you have “trunk†open in `work-dir`, with the repo file stored as
`repo.fossil` in that same directory.
Users of Git may be surprised that it doesn’t create a directory for you
and that you `cd` into it *before* the clone-and-open step, not after.
This is because we’re overloading the “open†command, which already had
the behavior of opening into the current working directory. Changing it
to behave like `git clone` would therefore make the behavior surprising
to Fossil users. (See [our discussions][caod] if you want the full
details.)
#### <a id="clone"></a> Git-Like Clone-and-Open
Fossil also supports a more Git-like alternative:
fossil clone https://fossil-scm.org/fossil
cd fossil
This results in a `fossil.fossil` repo DB file and a `fossil/` working
directory.
Note that our `clone URI` behavior does not commingle the repo and
check-out, solving our major problem with the Git design.
If you want the repo to be named something else, adjust the URL:
fossil clone https://fossil-scm.org/fossil/fsl
That gets you `fsl.fossil` checked out into `fsl/`.
For sites where the repo isn’t served from a subdirectory like this, you
might need another form of the URL. For example, you might have your
repo served from `dev.example.com` and want it cloned as `my-project`:
fossil clone https://dev.example.com/repo/my-project
The `/repo` addition is the key: whatever comes after is used as the
repository name. [See the docs][clone] for more details.

# Checkout vs Update
Fossil has two commands that look like they do the same thing on initial
examination, [`fossil update`][up] and [`fossil checkout`][co], but
there are several key differences:
1. `fossil checkout` aborts if there are changed files in the local
directory unless you give the `--force` option, whereas
`fossil update` merges upstream changes with your local changes.
Since Fossil tends to follow the CVS command design, and CVS
popularized the [merge on update][cvsmu] workflow, we expect that
Fossil’s update behavior is more likely to be what you want.
2. Update triggers an autosync attempt; checkout does not.
3. Several features in `fossil update` do not exist in
`fossil checkout`, so developing a habit to type `fossil up`
means you’re more likely to have the features you want at hand.
4. Inversely, the `fossil checkout --keep` feature doesn’t exist in
`fossil update`, but it’s a rarely-needed operation, so it doesn’t
provide a good reason to develop a habit of using `fossil checkout`
instead.
In summary, these are two separate commands; neither is an alias for the
other. They overlap enough that they can be used interchangeably for
some use cases, but `update` is more powerful and more broadly useful.

# Colorized Diffs
The oldest and most widely compatible method to get colorized diffs in
Fossil is to use its web UI:
fossil ui --page '/vdiff?from=2024-04-01&to=trunk'
That syntax is admittedly awkward, and it doesn’t work where “from†is
the current checkout. Fortunately, there are many other methods to get
colorized `diff` output from Fossil.
<a id="ui"></a>
## `fossil diff -b`
This produces a graphical diff in HTML format and sends it to the
user’s default web browser for viewing.
<a id="ui"></a>
## `fossil diff -tk`
You may be surprised to learn that the prior feature doesn’t use any of
the skinning or chrome from Fossil UI. This is because it is meant as a
functional replacement for an older method of getting colorized diffs,
“`fossil diff -tk`â€. The feature was added after Apple stopped shipping
Tcl/Tk in macOS, and the third-party replacements often failed to work
correctly. It’s useful on other platforms as well.
<a id="git"></a>
## Delegate to Git
It may be considered sacrilege by some, but the most direct method for
those who want Git-like diff behavior may be to delegate diff behavior
to Git:
fossil set --global diff-command 'git diff --no-index'
The flag permits it to diff files that aren’t inside a Git repository.
<a id="diffutils"></a>
## GNU Diffutils
If your system is from 2016 or later, it may include [GNU Diffutils][gd]
3.4 or newer, which lets you say:
fossil set --global diff-command 'diff -dwu --color=always'
You might think you could give `--color=auto`, but that fails with
commands like “`fossil diff | less`†since the pipe turns the output
non-interactive from the perspective of the underlying `diff` instance.
This use of unconditional colorization means you will then have to
remember to add the `-i` option to `fossil diff` commands when producing
`patch(1)` files or piping diff output to another command that doesn’t
understand ANSI escape sequences, such as [`diffstat`][ds].
[ds]: https://invisible-island.net/diffstat/
[gd]: https://www.gnu.org/software/diffutils/
<a id="bat"></a>
## Bat, the Cat with Wings
We can work around the `--color=auto` problem by switching from GNU less
as our pager to [`bat`][bat], as it can detect GNU diff output and
colorize it for you:
fossil set --global diff-command 'diff -dwu --color=auto'
fossil diff | bat
In this author’s experience, that works a lot more reliably than GNU
less’s ANSI color escape code handling, even when you set `LESS=-R` in
your environment.
The reason we don’t leave the `diff-command` unset in this case is that
Fossil produces additional lines at the start which confuse the diff
format detection in `bat`. Forcing output through an external diff
command solves that. It also means that if you forget to pipe the output
through `bat`, you still get colorized output from GNU diff.
[bat]: https://github.com/sharkdp/bat
<a id="colordiff"></a>
## Colordiff
A method that works on systems predating GNU diffutils 3.4 or the
widespread availability of `bat` is to install [`colordiff`][cdurl], as
it is included in [many package systems][cdpkg], including ones for
outdated OSes. That then lets you say:
fossil set --global diff-command 'colordiff -dwu'
The main reason we list this alternative last is that it has the same
limitation of unconditional color as [above](#diffutils).

<title>Fossil Concepts</title>
<h2>1.0 Introduction</h2>
[./index.wiki | Fossil] is a
[http://en.wikipedia.org/wiki/Software_configuration_management | software configuration management] system.
Fossil is software that is designed to control and track the
development of a software project and to record the history
of the project.
There are many such systems in use today. Fossil strives to
distinguish itself from the others by being extremely simple
to setup and operate.
This document is intended as a quick introduction to the concepts
behind Fossil.

</verbatim>
A software project normally consists of a "source tree".
A source tree is a hierarchy of files that are used to generate
the end product. The source tree changes over time as the
software grows and expands and as features are added and bugs
are fixed. A snapshot of the source tree at any point in time
is called a "version" or "revision" or a "baseline" of the product.
In Fossil, we use the name "check-in".
A "repository" is a database that contains copies of all historical
check-ins for a project. Check-ins are normally stored in the
repository in a highly space-efficient compressed format (delta encoding).
But that is an implementation detail that you the user need not worry over.
Think of the repository as a safe place where all your old check-ins are
securely stored away and available for retrieval whenever you need
them.
A repository in Fossil is a single file on your disk. This file
might be rather large (dozens or hundreds of megabytes for a large
or long running project) but it is nevertheless just a file. You
can move it around, rename it, write it out to a memory stick, or
do anything else you normally do with files.
Each source tree that is controlled by Fossil is associated with
a single repository on the local disk drive. You can tie two or more
source trees to a single repository if you want (though one
tree per repository is the most common configuration.) So a
single repository can be associated with many source trees, but
each source tree is associated with only one repository.
Fossil source trees may not overlap. A Fossil source tree is identified
by a file named "_FOSSIL_" (or ".fslckout", but this article will always
use the name "_FOSSIL_") in the root directory of the source tree. Every
file that is a sibling of _FOSSIL_ and every file in every subfolder is
considered potentially a part of the source tree. The _FOSSIL_ file
contains (among other things) the pathname of the repository with which
the source tree is associated. On the other hand, the repository has
no record of its source trees. So you are free to delete a source tree
or move it around without consequence. But if you move or rename or
delete a repository, then any source trees associated with that repository

A "clone" is like a "pull", except that instead of beginning with an existing local repository, a clone begins with nothing and creates a new local repository that is a duplicate of a remote repository. Communication between repositories is normally via HTTPS. (SSH is also supported, as is unencrypted HTTP.) Remote repositories are identified by URL. You can also point a web browser at a repository and get human-readable status, history, and tracking information about the project. <h3 id="artifacts">2.1 Identification Of Artifacts</h3> A particular version of a particular file is called an "artifact". Each artifact has a universally unique name which is the <a href="http://en.wikipedia.org/wiki/SHA1">SHA1</a> or <a href="http://en.wikipedia.org/wiki/SHA3">SHA3-256</a> hash of the content of that file expressed as either 40 or 64 characters of lower-case hexadecimal. (See the [./hashpolicy.wiki|hash policy document] for information on which algorithm is used, when.) Such a hash is referred to as the Artifact ID. These hash algorithms were created with Fossil's purpose in mind: to provide a highly forgery-resistant identifier for a blob of data, such as a file. Given any file, it is simple to find the artifact ID for that file. But given an artifact ID, it is computationally intractable to generate a file that will have that same artifact ID. Artifact IDs look something like this: <pre> 6089f0b563a9db0a6d90682fe47fd7161ff867c8 59712614a1b3ccfd84078a37fa5b606e28434326 19dbf73078be9779edd6a0156195e610f81c94f9 b4104959a67175f02d6b415480be22a239f1f077 997c9d6ae03ad114b2b57f04e9eeef17dcb82788 </pre> When referring to an artifact using Fossil, you can use a unique prefix of the artifact ID that is four characters or longer. This saves a lot of typing. When displaying artifact IDs, Fossil will usually only show the first 10 digits since that is normally enough to uniquely identify a file. Changing (or adding or removing) a single byte in a file results in a completely different artifact ID. And since the artifact ID is the name of the artifact, making any change to a file results in a new artifact. In this way, artifacts are immutable. |

such a way that it can be handed a set of artifacts in any
order and it can figure out the relationship between those
artifacts and reconstruct the complete development history of
a software project.
<h3>2.2 Manifests</h3>
Associated with every check-in is a special file called the
[./fileformat.wiki#manifest| "manifest"]. The manifest is a
listing of all other files in
that source tree. The manifest contains the (complete) artifact ID
of the file and the name of the file as it appears on disk,
and thus serves as a mapping from artifact ID to disk name. The artifact ID
of the manifest is the identifier for the entire check-in. When
you look at a "timeline" of changes in Fossil, the ID associated
with each check-in or commit is really just the artifact ID of the
manifest for that check-in.
The manifest file is not normally a real file on disk. Instead,
the manifest is computed in memory by Fossil whenever it needs it.
However, the "fossil setting manifest on" command will cause the
manifest file to be materialized to disk, if desired. Both Fossil
itself, and SQLite cause the manifest file to be materialized to disk
so that the makefiles for these projects can read the manifest and
embed version information in generated binaries.
Fossil automatically generates a manifest whenever you "commit"
a new check-in. So this is not something that you, the developer,
need to worry with. The format of a manifest is intentionally
designed to be simple to parse, so that if
you want to read and interpret a manifest, either by hand or
with a script, that is easy to do. But you will probably never
need to do so.
In addition to identifying all files in the check-in, a
manifest also contains a check-in comment, the date and time
when the check-in was established, who created the check-in,
and links to other check-ins from which the current check-in
is derived. There are also a couple of checksums used to verify
the integrity of the check-in. And the whole manifest might
be PGP clearsigned.

<h2>3.0 Fossil - The Program</h2>
Fossil is software. The implementation of Fossil is in the form
of a single executable named "fossil" (or "fossil.exe" on Windows).
To install Fossil on your system,
all you have to do is obtain a copy of this one executable file (either
by downloading a
<a href="https://fossil-scm.org/home/uv/download.html">pre-compiled version</a>
or [./build.wiki | compiling it yourself]) and then
putting that file somewhere on your PATH.
Fossil is completely self-contained. It is not necessary to
install any other software in order to use Fossil. You do <u>not</u> need
CVS, gzip, diff, rsync, Python, Perl, Tcl, Java, Apache, PostgreSQL, MySQL,
SQLite, patch, or any similar software on your system in order to use
Fossil effectively. You will want to have some kind of text editor
for entering check-in comments. Fossil will use whatever text editor
is identified by your VISUAL environment variable. Fossil will also
use GPG to clearsign your manifests if you happen to have it installed,
but Fossil will skip that step if GPG is missing from your system.
You can optionally set up Fossil to use external "diff" programs,
though Fossil has an excellent built-in "diff" algorithm that works
fine for most people. If you happen to have Tcl/Tk installed on your
system, Fossil will use it to generate a graphical "diff" display when
you use the --tk option to the "diff" command, but this too is entirely
optional.
To uninstall Fossil, simply delete the executable.
To upgrade an older version of Fossil to a newer version, just
replace the old executable with the new one. You might need to
run "<b>fossil all rebuild</b>" to restructure your repositories after
an upgrade. Running "all rebuild" never hurts, so when upgrading it
is a good policy to run it even if it is not strictly necessary.
To use Fossil, simply type the name of the executable in your
shell, followed by one of the various built-in commands and
arguments appropriate for that command. For example:
<pre>fossil help</pre>
In the next section, when we say things like "use the <b>help</b>
command" we mean to use the command name "help" as the first
token after the name of the Fossil executable, as shown above.

Fossil has two modes of operation: <i>"autosync"</i> and
<i>"manual-merge"</i>
Autosync mode is reminiscent of CVS or SVN in that it automatically
keeps your changes in synchronization with your co-workers through
the use of a central server. The manual-merge mode is the standard workflow
for GIT or Mercurial in that your local repository develops
independently of your coworkers and you share and merge your changes manually.
An interesting feature of Fossil is that it supports both autosync
and manual-merge work flows.
The default setting for Fossil is to be in autosync mode. You
can change the autosync setting or check the current autosync
setting using commands like:
<pre>
fossil setting autosync on
fossil setting autosync off
fossil settings
</pre>
By default, Fossil runs with autosync mode turned on. The
authors find that projects run more smoothly in autosync mode since
autosync helps to prevent pointless forking and merging and helps keeps
all collaborators working on exactly the same code rather than on their
own personal forks of the code. In the author's view, manual-merge mode
should be reserved for disconnected operation.
<h3>4.1 Autosync Workflow</h3>
<ol>
<li>
Establish a local repository using either the <b>new</b> command
to start a new project, or the <b>clone</b> command to make a clone
of a repository for an existing project.
</li>
<li>
Establish one or more source trees using
the <b>open</b> command with the name of the repository file as its
argument.
</li>
<li>
The <b>open</b> command in the previous step populates your local source
tree with a copy of the latest check-in. Usually this is what you want.
In the rare cases where it is not, use the <b>update</b> command to
switch to a different check-in.
Use the <b>timeline</b> or <b>leaves</b> commands
to identify alternative check-ins to switch to.
</li>
<li>
Edit the code. Add new files to the source tree using the <b>add</b>
command. Omit files from future check-ins using the <b>rm</b> command.
(Even when you remove files from future check-ins, those files continue
to exist in historical check-ins.) Test your changes.
</li>
<li>
Create a new check-in using the <b>commit</b> command. You will be prompted
for a check-in comment and also for your GPG key if you have GPG installed.
The commit copies the edits you have made in your local source
tree into your local repository. After your commit completes, Fossil will
automatically <b>push</b> your changes back to the server
you cloned from or whatever server you most recently synced with.
</li>
<li>
When your coworkers make their own changes, you can merge those changes
into your local local source tree using the <b>update</b> command.
In autosync mode, <b>update</b> will first go back to the server you
cloned from or with which you most recently synced, and pull down all
recent changes into your local repository. Then it will merge recent
changes into your local source tree. If you do an <b>update</b> and
find that it messes something up in your source tree (perhaps a co-worker
checked in incompatible changes) you can use the <b>undo</b> command

<h2>5.0 Setting Up A Fossil Server</h2>
With other configuration management software, setting up a server is
a lot of work and normally takes time, patience, and a lot of system
knowledge. Fossil is designed to avoid this frustration. Setting up
a server with Fossil is ridiculously easy. You have four options:
# <b>Stand-alone server.</b>
Simply run the [/help?cmd=server|fossil server] or
[/help?cmd=ui|fossil ui] command from the command-line.
<br><br>
# <b>CGI.</b>
Install a 2-line CGI script on a CGI-enabled web-server like Apache.
<br><br>
# <b>SCGI.</b>
Start an SCGI server using the
[/help?cmd=server| fossil server --scgi] command for handling
SCGI requests from web-servers like Nginx.
<br><br>
# <b>Inetd or Stunnel.</b>
Configure programs like inetd, xinetd, or stunnel to hand off HTTP requests
directly to the [/help?cmd=http|fossil http] command.
See the [./server/ | How To Configure A Fossil Server] document
for details.
<h2>6.0 Review Of Key Concepts</h2>
<ul>
<li>The <b>fossil</b> program is a self-contained stand-alone executable.
Just put it somewhere on your PATH to install it.</li>
<li>Use the <b>clone</b> or <b>new</b> commands to create a new repository.</li>

# OCI Containers
This document shows how to build Fossil into [OCI] compatible containers
and how to use those containers in interesting ways. We start off using
the original and still most popular container development and runtime
platform, [Docker], but since you have more options than that, we will
show some of these options later on.
[Docker]: https://www.docker.com/
[OCI]: https://opencontainers.org/
## 1. Quick Start
Fossil ships a `Dockerfile` at the top of its source tree,
[here][DF], which you can build like so:
$ docker build -t fossil .
If the image built successfully, you can create a container from it and
test that it runs:
$ docker run --name fossil -p 9999:8080/tcp fossil
This shows us remapping the internal TCP listening port as 9999 on the
host. This feature of OCI runtimes means there’s little point to using
the “`fossil server --port`†feature inside the container. We can let
Fossil default to 8080 internally, then remap it to wherever we want it
on the host instead.
Our stock `Dockerfile` configures Fossil with the default feature set,
so you may wish to modify the `Dockerfile` to add configuration options,
add APK packages to support those options, and so forth.
The Fossil `Makefile` provides two convenience targets,
“`make container-image`†and “`make container-run`â€. The first creates a
versioned container image, and the second does that and then launches a
fresh container based on that image. You can pass extra arguments to the
first command via the Makefile’s `DBFLAGS` variable and to the second
with the `DCFLAGS` variable. (DB is short for “`docker build`â€, and DC
is short for “`docker create`â€, a sub-step of the “run†target.)
To get the custom port setting as in
second command above, say:
$ make container-run DCFLAGS='-p 9999:8080/tcp'
Contrast the raw “`docker`†commands above, which create an
_unversioned_ image called `fossil:latest` and from that a container
simply called `fossil`. The unversioned names are more convenient for
interactive use, while the versioned ones are good for CI/CD type
applications since they avoid a conflict with past versions; it lets you
keep old containers around for quick roll-backs while replacing them
with fresh ones.
[DF]: /file/Dockerfile
## 2. <a id="storage"></a>Repository Storage Options
If you want the container to serve an existing repository, there are at
least two right ways to do it.
The wrong way is to use the `Dockerfile COPY` command, because by baking
the repo into the image at build time, it will become one of the image’s
base layers. The end result is that each time you build a container from
that image, the repo will be reset to its build-time state. Worse,
restarting the container will do the same thing, since the base image
layers are immutable. This is almost certainly not what you
want.
The correct ways put the repo into the _container_ created from the
_image_, not in the image itself.
### <a id="repo-inside"></a> 2.1 Storing the Repo Inside the Container
The simplest method is to stop the container if it was running, then
say:
$ docker cp /path/to/my-project.fossil fossil:/museum/repo.fossil
$ docker start fossil
$ docker exec fossil chown -R 499 /museum
That copies the local Fossil repo into the container where the server
expects to find it, so that the “start†command causes it to serve from
that copied-in file instead. Since it lives atop the immutable base
layers, it persists as part of the container proper, surviving restarts.
Notice that the copy command changes the name of the repository
database. The container configuration expects it to be called
`repo.fossil`, which it almost certainly was not out on the host system.
This is because there is only one repository inside this container, so
we don’t have to name it after the project it contains, as is
traditional. A generic name lets us hard-code the server start command.
If you skip the “chown†command above and put “`http://localhost:9999/`â€
into your browser, expecting to see the copied-in repo’s home page, you
will get an opaque “Not Found†error. This is because the user and group
ID of the file will be that of your local user on the container’s host
machine, which is unlikely to map to anything in the container’s
`/etc/passwd` and `/etc/group` files, effectively preventing the server
from reading the copied-in repository file. 499 is the default “`fossil`â€
user ID inside the container, causing Fossil to run with that user’s
privileges after it enters the chroot. (See [below](#args) for how to
change this default.) You don’t have to restart the server after fixing
this with `chmod`: simply reload the browser, and Fossil will try again.
### 2.2 <a id="bind-mount"></a>Storing the Repo Outside the Container
The simple storage method above has a problem: containers are
designed to be killed off at the slightest cause, rebuilt, and
redeployed. If you do that with the repo inside the container, it gets
destroyed, too. The solution is to replace the “run†command above with
the following:
$ docker run \
--publish 9999:8080 \
--name fossil-bind-mount \
--volume ~/museum:/museum \
fossil
Because this bind mount maps a host-side directory (`~/museum`) into the
container, you don’t need to `docker cp` the repo into the container at
all. It still expects to find the repository as `repo.fossil` under that
directory, but now both the host and the container can see that repo DB.
Instead of a bind mount, you could instead set up a separate
[volume](https://docs.docker.com/storage/volumes/), at which point you
_would_ need to `docker cp` the repo file into the container.
Either way, files in these mounted directories have a lifetime
independent of the container(s) they’re mounted into. When you need to
rebuild the container or its underlying image — such as to upgrade to a
newer version of Fossil — the external directory remains behind and gets
remapped into the new container when you recreate it with `--volume/-v`.
#### 2.2.1 <a id="wal-mode"></a>WAL Mode Interactions
You might be aware that OCI containers allow mapping a single file into
the repository rather than a whole directory. Since Fossil repositories
are specially-formatted SQLite databases, you might be wondering why we
don’t say things like:
--volume ~/museum/my-project.fossil:/museum/repo.fossil
That lets us have a convenient file name for the project outside the
container while letting the configuration inside the container refer to
the generic “`/museum/repo.fossil`†name. Why should we have to name
the repo generically on the outside merely to placate the container?
The reason is, you might be serving that repo with [WAL mode][wal]
enabled. If you map the repo DB alone into the container, the Fossil
instance inside the container will write the `-journal` and `-wal` files
alongside the mapped-in repository inside the container. That’s fine as
far as it goes, but if you then try using the same repo DB from outside
the container while there’s an active WAL, the Fossil instance outside
won’t know about it. It will think it needs to write *its own*
`-journal` and `-wal` files *outside* the container, creating a high
risk of [database corruption][dbcorr].
If we map a whole directory, both sides see the same set of WAL files.
[Testing](https://tangentsoft.com/sqlite/dir/walbanger?ci=trunk)
gives us a reasonable level of confidence that using WAL across a
container boundary is safe when used in this manner.

Prior to 2023.03.26, the stock Fossil container relied on [the chroot
jail feature](./chroot.md) to wall away the shell and other tools
provided by [BusyBox]. It included that as a bare-bones operating system
inside the container on the off chance that someone might need it for
debugging, but the thing is, Fossil is self-contained, needing none of
that power in the main-line use cases.
Our weak “you might need it†justification collapsed when we realized
you could restore this basic shell environment with a one-line change to
the `Dockerfile`, as shown [below](#run).
[BusyBox]: https://www.busybox.net/BusyBox.html
### 3.2 <a id="caps"></a>Dropping Unnecessary Capabilities
The example commands above create the container with [a default set of
Linux kernel capabilities][defcap]. Although Docker strips away almost
all of the traditional root capabilities by default, and Fossil doesn’t
need any of those it does take away, Docker does leave some enabled that
Fossil doesn’t actually need. You can tighten the scope of capabilities
by adding “`--cap-drop`†options to your container creation commands.
Specifically:
* **`AUDIT_WRITE`**: Fossil doesn’t write to the kernel’s auditing
log, and we can’t see any reason you’d want to be able to do that as
an administrator shelled into the container, either. Auditing is
something done on the host, not from inside each individual
container.
* **`CHOWN`**: The Fossil server never even calls `chown(2)`, and our
image build process sets up all file ownership properly, to the
extent that this is possible under the limitations of our
automation.
Curiously, stripping this capability doesn’t affect your ability to
run commands like “`chown -R fossil:fossil /museum`†when
you’re using bind mounts or external volumes — as we recommend
[above](#bind-mount) — because it’s the host OS’s kernel
capabilities that affect the underlying `chown(2)` call in that
case, not those of the container.
If for some reason you did have to change file ownership of
in-container files, it’s best to do that by changing the
`Dockerfile` to suit, then rebuilding the container, since that
bakes the need for the change into your reproducible build process.
If you had to do it without rebuilding the container, [there’s a
workaround][capchg] for the fact that capabilities are a create-time
change, baked semi-indelibly into the container configuration.
* **`FSETID`**: Fossil doesn’t use the SUID and SGID bits itself, and
our build process doesn’t set those flags on any of the files.
Although the second fact means we can’t see any harm from leaving
this enabled, we also can’t see any good reason to allow it, so we
strip it.
* **`KILL`**: The only place Fossil calls `kill(2)` is in the
[backoffice], and then only for processes it created on earlier
runs; it doesn’t need the ability to kill processes created by other
users. You might wish for this ability as an administrator shelled
into the container, but you can pass the “`docker exec --user`â€
option to run commands within your container as the legitimate owner
of the process, removing the need for this capability.
* **`MKNOD`**: As of 2023.03.26, the stock container uses the
runtime’s default `/dev` node tree. Prior to this, we had to create
`/dev/null` and `/dev/urandom` inside [the chroot jail](#chroot),
but even then, these device nodes were created at build time and
were never changed at run time, so we didn’t need this run-time
capability even then.
* **`NET_BIND_SERVICE`**: With containerized deployment, Fossil never
needs the ability to bind the server to low-numbered TCP ports, not
even if you’re running the server in production with TLS enabled and
want the service bound to port 443. It’s perfectly fine to let the
Fossil instance inside the container bind to its default port (8080)
because you can rebind it on the host with the
“`docker create --publish 443:8080`†option. It’s the container’s
_host_ that needs this ability, not the container itself.
(Even the container runtime might not need that capability if you’re
[terminating TLS with a front-end proxy](./ssl.wiki#server). You’re
more likely to say something like “`-p localhost:12345:8080`†and then
configure the reverse proxy to translate external HTTPS calls into
HTTP directed at this internal port 12345.)
* **`NET_RAW`**: Fossil itself doesn’t use raw sockets, and while
you could [swap out the run layer](#run) for something more
functional that *does* make use of raw sockets, there’s little call
for it. The best reason I can come up with is to be able to run
utilities like `ping` and `traceroute`, but since we aren’t doing
anything clever with the networking configuration, there’s no
particularly compelling reason to run these from inside the
container. If you need to ping something, do it on the host.
If we did not take this hard-line stance, an attacker that broke
into the container and gained root privileges might use raw sockets
to do a wide array of bad things to any network the container is
bound to.
* **`SETFCAP, SETPCAP`**: There isn’t much call for file permission
granularity beyond the classic Unix ones inside the container, so we
drop root’s ability to change them.
All together, we recommend adding the following options to your
“`docker run`†commands, as well as to any “`docker create`†command
that will be followed by “`docker start`â€:
--cap-drop AUDIT_WRITE \
--cap-drop CHOWN \
--cap-drop FSETID \
--cap-drop KILL \
--cap-drop MKNOD \
--cap-drop NET_BIND_SERVICE \
--cap-drop NET_RAW \
--cap-drop SETFCAP \
--cap-drop SETPCAP
In the next section, we’ll show a case where you create a container
without ever running it, making these options pointless.

## 4. <a id="static"></a>Extracting a Static Binary
Our 2-stage build process uses Alpine Linux only as a build host. Once
we’ve got everything reduced to a single static Fossil binary,
we throw all the rest of it away.
A secondary benefit falls out of this process for free: it’s arguably
the easiest way to build a purely static Fossil binary for Linux. Most
modern Linux distros make this [surprisingly difficult][lsl], but Alpine’s
back-to-basics nature makes static builds work the way they used to,
back in the day. If that’s all you’re after, you can do so as easily as
this:
$ docker build -t fossil .
$ docker create --name fossil-static-tmp fossil
$ docker cp fossil-static-tmp:/bin/fossil .
$ docker container rm fossil-static-tmp
The result is six or seven megs, depending on the CPU architecture you
build for. It’s built stripped.

## 5. <a id="custom" name="args"></a>Customization Points
### <a id="pkg-vers"></a> 5.1 Fossil Version
The default version of Fossil fetched in the build is the version in the
checkout directory at the time you run it. You could override it to get
a release build like so:
$ docker build -t fossil --build-arg FSLVER=version-2.20 .
Or equivalently, using Fossil’s `Makefile` convenience target:
$ make container-image DBFLAGS='--build-arg FSLVER=version-2.20'
While you could instead use the generic
“`release`†tag here, it’s better to use a specific version number
since container builders cache downloaded files, hoping to
reuse them across builds. If you ask for “`release`†before a new
version is tagged and then immediately after, you might expect to get
two different tarballs, but because the underlying source tarball URL
remains the same when you do that, you’ll end up reusing the
old tarball from cache. This will occur
even if you pass the “`docker build --no-cache`†option.
This is why we default to pulling the Fossil tarball by checkin ID
rather than let it default to the generic “`trunk`†tag: so the URL will
change each time you update your Fossil source tree, forcing the builder to
pull a fresh tarball.
### 5.2 <a id="uids"></a>User & Group IDs
The “`fossil`†user and group IDs inside the container default to 499.
Why? Regular user IDs start at 500 or 1000 on most Unix type systems,
leaving those below it for system users like this Fossil daemon owner.
Since it’s typical for these to start at 0 and go upward, we started at
500 and went *down* one instead to reduce the chance of a conflict to as
close to zero as we can manage.
To change it to something else, say:
$ make container-image DBFLAGS='--build-arg UID=501'
This is particularly useful if you’re putting your repository on a
separate volume since the IDs “leak†out into the host environment via
file permissions. You may therefore wish them to mean something on both
sides of the container barrier rather than have “499†appear on the host
in “`ls -l`†output.
### 5.3 <a id="cengine"></a>Container Engine
Although the Fossil container build system defaults to Docker, we allow
for use of any OCI container system that implements the same interfaces.
We go into more details about this [below](#light), but
for now, it suffices to point out that you can switch to Podman while
using our `Makefile` convenience targets unchanged by saying:
$ make CENGINE=podman container-run
### 5.4 <a id="config"></a>Fossil Configuration Options
You can use this same mechanism to enable non-default Fossil
configuration options in your build. For instance, to turn on
the JSON API and the TH1 docs extension:
$ make container-image \
DBFLAGS='--build-arg FSLCFG="--json --with-th1-docs"'
If you also wanted [the Tcl evaluation extension](./th1.md#tclEval),
that brings us to [the next point](#run).
### 5.5 <a id="run"></a>Elaborating the Run Layer
If you want a basic shell environment for temporary debugging of the
running container, that’s easily added. Simply change this line in the
`Dockerfile`…
FROM scratch AS run
…to this:
FROM busybox AS run
Rebuild and redeploy to give your Fossil container a [BusyBox]-based
shell environment that you can get into via:
$ docker exec -it -u fossil $(make container-version) sh
That command assumes you built it via “`make container`†and are
therefore using its versioning scheme.
You will likely want to remove the `PATH` override in the “RUN†stage
when doing this since it’s written for the case where everything is in
`/bin`, and that will no longer be the case with a more full-featured
“`run`†layer. As long as the parent layer’s `PATH` value contains
`/bin`, delegating to it is more likely the correct thing.
Another useful case to consider is that you’ve installed a [server
extension](./serverext.wiki) and you need an interpreter for that
script. The first option above won’t work except in the unlikely case that
it’s written for one of the bare-bones script interpreters that BusyBox
ships.(^[BusyBox]’s `/bin/sh` is based on the old 4.4BSD Lite Almquist
shell, implementing little more than what POSIX specified in 1989, plus
equally stripped-down versions of `awk` and `sed`.)
Let’s say the extension is written in Python. Because this is one of the
most popular programming languages in the world, we have many options
for achieving this. For instance, there is a whole class of
“[distroless]†images that will do this efficiently by changing
“`STAGE 2`†in the `Dockefile` to this:
## ---------------------------------------------------------------------
## STAGE 2: Pare that back to the bare essentials, plus Python.
## ---------------------------------------------------------------------
FROM cgr.dev/chainguard/python:latest
USER root
ARG UID=499
ENV PATH "/sbin:/usr/sbin:/bin:/usr/bin"
COPY --from=builder /tmp/fossil /bin/
COPY --from=builder /bin/busybox.static /bin/busybox
RUN [ "/bin/busybox", "--install", "/bin" ]
RUN set -x \
&& echo "fossil:x:${UID}:${UID}:User:/museum:/false" >> /etc/passwd \
&& echo "fossil:x:${UID}:fossil" >> /etc/group \
&& install -d -m 700 -o fossil -g fossil log museum
You will also have to add `busybox-static` to the APK package list in
STAGE 1 for the `RUN` script at the end of that stage to work, since the
[Chainguard Python image][cgimgs] lacks a shell, on purpose. The need to
install root-level binaries is why we change `USER` temporarily here.
Build it and test that it works like so:
$ make container-run &&
docker exec -i $(make container-version) python --version
3.11.2
The compensation for the hassle of using Chainguard over something more
general purpose like changing the `run` layer to Alpine and then adding
a “`apk add python`†command to the `Dockerfile`
is huge: we no longer leave a package manager sitting around inside the
container, waiting for some malefactor to figure out how to abuse it.
Beware that there’s a limit to this über-jail’s ability to save you when
you go and provide a more capable runtime layer like this. The container
layer should stop an attacker from accessing any files out on the host
that you haven’t explicitly mounted into the container’s namespace, but
it can’t stop them from making outbound network connections or modifying
the repo DB inside the container.

### 5.6 <a id="alerts"></a>Email Alerts
The nature of our single static binary container precludes two of the
options for [sending email alerts](./alerts.md) from Fossil:
* pipe to a command
* SMTP relay host
There is no `/usr/sbin/sendmail` inside the container, and the container
cannot connect out to a TCP service on the host by default.
While it is possible to get around the first lack by [elaborating the
run layer](#run), to inject a full-blown Sendmail setup into the
container would go against the whole idea of containerization.
Forwarding an SMTP relay port into the container isn’t nearly as bad,
but it’s still bending the intent behind containers out of shape.
A far better option in this case is the “store emails in databaseâ€
method since the containerized Fossil binary knows perfectly well how to
write SQLite DB files without relying on any external code. Using the
paths in the configuration recommended above, the database path should
be set to something like `/museum/mail.db`. This, along with the use of
[bind mounts](#bind-mount) means you can have a process running outside
the container that passes the emails along to the host-side MTA.
The included [`email-sender.tcl`](/file/tools/email-sender.tcl) script
works reasonably well for this, though in my own usage, I had to make
two changes to it:
1. The shebang line at the top has to be `#!/usr/bin/tclsh` on my server.
2. I parameterized the `DBFILE` variable at the top thus:
set DBFILE [lindex $argv 0]
I then wanted a way to start this Tcl script on startup and keep it
running, which made me reach for systemd. My server is set to allow user
services to run at boot(^â€Desktop†class Linuxes tend to disable that by
default under the theory that you don’t want those services to run until
you’ve logged into the GUI as that user. If you find yourself running
into this, [enable linger
mode](https://www.freedesktop.org/software/systemd/man/loginctl.html).)
so I was able to create a unit file called
`~/.local/share/systemd/user/alert-sender@.service` with these contents:
[Unit]
Description=Fossil email alert sender for %I
[Service]
WorkingDirectory=/home/fossil/museum
ExecStart=/home/fossil/bin/alert-sender %I/mail.db
Restart=always
RestartSec=3
[Install]
WantedBy=default.target
I was then able to enable email alert forwarding for select repositories
after configuring them per [the docs](./alerts.md) by saying:
$ systemctl --user daemon-reload
$ systemctl --user enable alert-sender@myproject
$ systemctl --user start alert-sender@myproject
Because this is a parameterized script and we’ve set our repository
paths predictably, you can do this for as many repositories as you need
to by passing their names after the “`@`†sign in the commands above.
## 6. <a id="light"></a>Lightweight Alternatives to Docker
Those afflicted with sticker shock at seeing the size of a [Docker
Desktop][DD] installation — 1.65 GB here — might’ve immediately
“noped†out of the whole concept of containers. The first thing to
realize is that when it comes to actually serving simple containers like
the ones shown above is that [Docker Engine][DE] suffices, at about a
quarter of the size.
Yet on a small server — say, a $4/month ten gig Digital Ocean droplet —
that’s still a big chunk of your storage budget. It takes ~60:1 overhead
merely to run a Fossil server container? Once again, I wouldn’t
blame you if you noped right on out of here, but if you will be patient,
you will find that there are ways to run Fossil inside a container even
on entry-level cloud VPSes. These are well-suited to running Fossil; you
don’t have to resort to [raw Fossil service][srv] to succeed,
leaving the benefits of containerization to those with bigger budgets.
For the sake of simple examples in this section, we’ll assume you’re
integrating Fossil into a larger web site, such as with our [Debian +
nginx + TLS][DNT] plan. This is why all of the examples below create
the container with this option:
--publish 127.0.0.1:9999:8080
The assumption is that there’s a reverse proxy running somewhere that
redirects public web hits to localhost port 9999, which in turn goes to
port 8080 inside the container. This use of port
publishing effectively replaces the use of the
“`fossil server --localhost`†option.
For the nginx case, you need to add `--scgi` to these commands, and you
might also need to specify `--baseurl`.
Containers are a fine addition to such a scheme as they isolate the
Fossil sections of the site from the rest of the back-end resources,
thus greatly reducing the chance that they’ll ever be used to break into
the host as a whole.
(If you wanted to be double-safe, you could put the web server into
another container, restricting it to reading from the static web
site directory and connecting across localhost to back-end dynamic
content servers such as Fossil. That’s way outside the scope of this
document, but you can find ready advice for that elsewhere. Seeing how
we do this with Fossil should help you bridge the gap in extending
this idea to the rest of your site.)

### 6.1 <a id="nerdctl" name="containerd"></a>Stripping Docker Engine Down
The core of Docker Engine is its [`containerd`][ctrd] daemon and the
[`runc`][runc] container runtime. Add to this the out-of-core CLI program
[`nerdctl`][nerdctl] and you have enough of the engine to run Fossil
containers. The big things you’re missing are:
* **BuildKit**: The container build engine, which doesn’t matter if
you’re building elsewhere and shipping the images to the target.
A good example is using a container registry as an
intermediary between the build and deployment hosts.
* **SwarmKit**: A powerful yet simple orchestrator for Docker that you
probably aren’t using with Fossil anyway.
In exchange, you get a runtime that’s about half the size of Docker
Engine. The commands are essentially the same as above, but you say
“`nerdctl`†instead of “`docker`â€. You might alias one to the other,
because you’re still going to be using Docker to build and ship your
container images.

### 6.2 <a id="podman"></a>Podman
A lighter-weight [rootless][rl] [drop-in replacement][whatis] that
doesn’t give up the image builder is [Podman]. Initially created by
Red Hat and thus popular on that family of OSes, it will run on
any flavor of Linux. It can even be made to run [on macOS via Homebrew][pmmac]
or [on Windows via WSL2][pmwin].
On Ubuntu 22.04, the installation size is about 38 MiB, roughly a
tenth the size of Docker Engine.
For our purposes here, the only thing that changes relative to the
examples at the top of this document are the initial command:
$ podman build -t fossil .
$ podman run --name fossil -p 9999:8080/tcp fossil
Your Linux package repo may have a `podman-docker` package which
provides a “`docker`†script that calls “`podman`†for you, eliminating
even the command name difference. With that installed, the `make`
commands above will work with Podman as-is.
The only difference that matters here is that Podman doesn’t have the
same [default Linux kernel capability set](#caps) as Docker, which
affects the `--cap-drop` flags recommended above to:
$ podman create \
--name fossil \
--cap-drop CHOWN \
--cap-drop FSETID \
--cap-drop KILL \
--cap-drop NET_BIND_SERVICE \
--cap-drop SETFCAP \
--cap-drop SETPCAP \
--publish 127.0.0.1:9999:8080 \
localhost/fossil
$ podman start fossil

[whatis]: https://podman.io/whatis.html
### 6.3 <a id="nspawn"></a>`systemd-container`
If even the Podman stack is too big for you, the next-best option I’m
aware of is the `systemd-container` infrastructure on modern Linuxes,
available since version 239 or so. Its runtime tooling requires only
about 1.4Â MiB of disk space:
$ sudo apt install systemd-container btrfs-tools
That command assumes the primary test environment for
this guide, Ubuntu 22.04 LTS with `systemd` 249. For best
results, `/var/lib/machines` should be a btrfs volume, because
[`$REASONS`][mcfad]. For CentOS Stream 9 and other Red Hattish
systems, you will have to make several adjustments, which we’ve
collected [below](#nspawn-centos) to keep these examples clear.
We’ll assume your Fossil repository stores something called
“`myproject`†within `~/museum/myproject/repo.fossil`, named according
to the reasons given [above](#repo-inside). We’ll make consistent use of
this naming scheme in the examples below so that you will be able to
replace the “`myproject`†element of the various file and path names.
If you use [the stock `Dockerfile`][DF] to generate your
base image, `nspawn` won’t recognize it as containing an OS unless you
change the “`FROM scratch AS os`†line at the top of the second stage
to something like this:
FROM gcr.io/distroless/static-debian11 AS os
Using that as a base image provides all the files `nspawn` checks for to
determine whether the container is sufficiently close to a Linux VM for
the following step to proceed:
$ make container
$ docker container export $(make container-version) |
machinectl import-tar - myproject
Next, create `/etc/systemd/nspawn/myproject.nspawn`:
----
[Exec]
WorkingDirectory=/
Parameters=bin/fossil server \
--baseurl https://example.com/myproject \
--create \
--jsmode bundled \
--localhost \
--port 9000 \
--scgi \
--user admin \
museum/repo.fossil
DropCapability= \
CAP_AUDIT_WRITE \
CAP_CHOWN \
CAP_FSETID \
CAP_KILL \
CAP_MKNOD \
CAP_NET_BIND_SERVICE \
CAP_NET_RAW \
CAP_SETFCAP \
CAP_SETPCAP
ProcessTwo=yes
LinkJournal=no
Timezone=no
[Files]
Bind=/home/fossil/museum/myproject:/museum
[Network]
VirtualEthernet=no
----
If you recognize most of that from the `Dockerfile` discussion above,
congratulations, you’ve been paying attention. The rest should also
be clear from context.
Some of this is expected to vary:
* The references to `example.com` and `myproject` are stand-ins for
your actual web site and repository name.
* The command given in the `Parameters` directive assumes you’re
setting up [SCGI proxying via nginx][DNT], but with adjustment,
it’ll work with the other repository service methods we’ve
[documented][srv].
* The path in the host-side part of the `Bind` value must point at the
directory containing the `repo.fossil` file referenced in said
command so that `/museum/repo.fossil` refers to your repo out
on the host for the reasons given [above](#bind-mount).
That being done, we also need a generic `systemd` unit file called
`/etc/systemd/system/fossil@.service`, containing:
----
[Unit]
Description=Fossil %i Repo Service
Wants=modprobe@tun.service modprobe@loop.service
After=network.target systemd-resolved.service modprobe@tun.service modprobe@loop.service
[Service]
ExecStart=systemd-nspawn --settings=override --read-only --machine=%i bin/fossil
[Install]
WantedBy=multi-user.target
----
You shouldn’t have to change any of this because we’ve given the
`--setting=override` flag, meaning any setting in the nspawn file
overrides the setting passed to `systemd-nspawn`. This arrangement
not only keeps the unit file simple, it allows multiple services to
share the base configuration, varying on a per-repo level through
adjustments to their individual `*.nspawn` files.
You may then start the service in the normal way:
$ sudo systemctl enable fossil@myproject
$ sudo systemctl start fossil@myproject
You should then find it running on localhost port 9000 per the nspawn
configuration file above, suitable for proxying Fossil out to the
public using nginx via SCGI. If you aren’t using a front-end proxy
and want Fossil exposed to the world via HTTPS, you might say this instead in
the `*.nspawn` file:
Parameters=bin/fossil server \
--cert /path/to/cert.pem \
--create \
--jsmode bundled \
--port 443 \
--user admin \
museum/repo.fossil
You would also need to un-drop the `CAP_NET_BIND_SERVICE` capability
to allow Fossil to bind to this low-numbered port.
We use the `systemd` template file feature to allow multiple Fossil
servers running on a single machine, each on a different TCP port,
as when proxying them out as subdirectories of a larger site.
To add another project, you must first clone the base “machine†layer:
$ sudo machinectl clone myproject otherthing
That will not only create a clone of `/var/lib/machines/myproject`
as `../otherthing`, it will create a matching `otherthing.nspawn` file for you
as a copy of the first one. Adjust its contents to suit, then enable
and start it as above.

### 6.3.1 <a id="nspawn-rhel"></a>Getting It Working on a RHEL Clone
The biggest difference between doing this on OSes like CentOS versus
Ubuntu is that RHEL (thus also its clones) doesn’t ship btrfs in
its kernel, thus ships with no package repositories containing `mkfs.btrfs`, which
[`machinectl`][mctl] depends on for achieving its various purposes.
Fortunately, there are workarounds.
First, the `apt install` command above becomes:
$ sudo dnf install systemd-container
Second, you have to hack around the lack of `machinectl import-tar`:
$ rootfs=/var/lib/machines/fossil
$ sudo mkdir -p $rootfs
$ docker container export fossil | sudo tar -xf -C $rootfs -
The parent directory path in the `rootfs` variable is important,
because although we aren’t able to use `machinectl` on such systems, the
`systemd-nspawn` developers assume you’re using them together; when you give
`--machine`, it assumes the `machinectl` directory scheme. You could
instead use `--directory`, allowing you to store the rootfs wherever
you like, but why make things difficult? It’s a perfectly sensible
default, consistent with the [LHS] rules.
The final element — the machine name — can be anything
you like so long as it matches the nspawn file’s base name.
Finally, since you can’t use `machinectl clone`, you have to make
a wasteful copy of `/var/lib/machines/myproject` when standing up
multiple Fossil repo services on a single machine. (This is one
of the reasons `machinectl` depends on `btrfs`: cheap copy-on-write
subvolumes.) Because we give the `--read-only` flag, you can simply
`cp -r` one machine to a new name rather than go through the
export-and-import dance you used to create the first one.

### 6.3.2 <a id="nspawn-weaknesses"></a>What Am I Missing Out On?
For all the runtime size savings in this method, you may be wondering
what you’re missing out on relative to Podman, which takes up
roughly 27× more disk space. Short answer: lots. Long answer:
1. **Build system.** You’ll have to build and test your containers
some other way. This method is only suitable for running them
once they’re built.
2. **Orchestration.** All of the higher-level things like
“compose†files, Docker Swarm mode, and Kubernetes are
unavailable to you at this level. You can run multiple
instances of Fossil, but on a single machine only and with a
static configuration.
3. **Image layer sharing.** When you update an image using one of the
above methods, Docker and Podman are smart enough to copy only
changed layers. Furthermore, when you base multiple containers
on a single image, they don’t make copies of the base layers;
they can share them, because base layers are immutable, thus
cannot cross-contaminate.
Because we use `systemd-nspawn --read-only`, we get *some*
of this benefit, particularly when using `machinectl` with
`/var/lib/machines` as a btrfs volume. Even so, the disk space
and network I/O optimizations go deeper in the Docker and Podman
worlds.
4. **Tooling.** Hand-creating and modifying those `systemd`
files sucks compared to “`podman container create ...`†This
is but one of many affordances you will find in the runtimes
aimed at daily-use devops warriors.
5. **Network virtualization.** In the scheme above, we turn off the
`systemd` private networking support because in its default mode, it
wants to hide containerized services entirely. While there are
[ways][ndcmp] to expose Fossil’s single network service port under
that scheme, it adds a lot of administration complexity. In the
big-boy container runtimes, `docker create --publish` fixes all this
up in a single option, whereas `systemd-nspawn --port` does
approximately *none* of that despite the command’s superficial
similarity.
From a purely functional point of view, this isn’t a huge problem if
you consider the inbound service direction only, being external
connections to the Fossil service we’re providing. Since we do want
this Fossil service to be exposed — else why are we running it? — we
get all the control we need via `fossil server --localhost` and
similar options.
The complexity of the `systemd` networking infrastructure’s
interactions with containers make more sense when you consider the
outbound path. Consider what happens if you enable Fossil’s
optional TH1 docs feature plus its Tcl evaluation feature. That
would enable anyone with the rights to commit to your repository the
ability to make arbitrary network connections on the Fossil host.
Then, let us say you have a client-server DBMS server on that same
host, bound to localhost for private use by other services on the
machine. Now that DBMS is open to access by a rogue Fossil committer
because the host’s loopback interface is mapped directly into the
container’s network namespace.
Proper network virtualization would protect you in this instance.
This author expects that the set of considerations is broader than
presented here, but that it suffices to make our case as it is: if you
can afford the space of Podman or Docker, we strongly recommend using
either of them over the much lower-level `systemd-container`
infrastructure. You’re getting a considerable amount of value for the
higher runtime cost; it isn’t pointless overhead.
(Incidentally, these are essentially the same reasons why we no longer
talk about the `crun` tool underpinning Podman in this document. It’s
even more limited than `nspawn`, making it even more difficult to administer while
providing no runtime size advantage. The `runc` tool underpinning
Docker is even worse on this score, being scarcely easier to use than
`crun` while having a much larger footprint.)

### 6.3.3 <a id="nspawn-assumptions"></a>Violated Assumptions
The `systemd-container` infrastructure has a bunch of hard-coded
assumptions baked into it. We papered over these problems above,
but if you’re using these tools for other purposes on the machine
you’re serving Fossil from, you may need to know which assumptions
our container violates and the resulting consequences.
Some of it we discussed above already, but there’s one big class of
problems we haven’t covered yet. It stems from the fact that our stock
container starts a single static executable inside a bare-bones container
rather than “boot†an OS image. That causes a bunch of commands to fail:
* **`machinectl poweroff`** will fail because the container
isn’t running dbus.
* **`machinectl start`** will try to find an `/sbin/init`
program in the rootfs, which we haven’t got. We could
rename `/bin/fossil` to `/sbin/init` and then hack
the chroot scheme to match, but ick. (This, incidentally,
is why we set `ProcessTwo=yes` above even though Fossil is
perfectly capable of running as PID 1, a fact we depend on
in the other methods above.)
* **`machinectl shell`** will fail because there is no login
daemon running, which we purposefully avoided adding by
creating a “`FROM scratch`†container. (If you need a
shell, say: `sudo systemd-nspawn --machine=myproject /bin/sh`)
* **`machinectl status`** won’t give you the container logs
because we disabled the shared journal, which was in turn
necessary because we don’t run `systemd` *inside* the
container, just outside.
If these are problems for you, you may wish to build a
fatter container using `debootstrap` or similar. ([External
tutorial][medtut].)

<title>Contributing To Fossil</title>
Fossil users are encouraged to contribute enhancements back to the
project. This note outlines some of the procedures for making
useful contributions.
<h2>1.0 Contributor Agreement</h2>
In order to accept non-trivial contributions, we <u>must</u> have a
[./copyright-release.pdf | Contributor Agreement (PDF)]
(or [./copyright-release.html | as HTML]) on file for you. We require
this in order to maintain clear title to the Fossil code and prevent
the introduction of code with incompatible licenses or other entanglements
that might cause legal problems for Fossil users. Many
lawyer-rich organizations require this as a precondition to using
Fossil.
If you do not wish to submit a Contributor Agreement, we would still
welcome your suggestions and example code, but we will not use your code
directly: we will be forced to re-implement your changes from scratch, which
might take longer.
We've made exceptions for "trivial" changes in the past, but the
definition of that term is up to the project leader.
<h2>2.0 Submitting Patches</h2>
Suggested changes or bug fixes can be submitted by creating a patch
against the current source tree:
<pre>fossil diff -i > my-change.patch</pre>
Alternatively, you can create a binary patch:
<pre>fossil patch create my-change.db</pre>
Post patches to
[https://fossil-scm.org/forum | the forum] or email them to
<a href="mailto:drh@sqlite.org">drh@sqlite.org</a>. Be sure to
describe in detail what the patch does and which version of Fossil
it is written against. It's best to make patches against tip-of-trunk
rather than against past releases.
If your change is more complicated than a patch can properly encode, you
may submit [/help?cmd=bundle | a Fossil bundle] instead. Unlike patches,
bundles can contain multiple commits, check-in comments, file renames,
file deletions, branching decisions, and more which <tt>patch(1)</tt>
files cannot. It's best to make a bundle of a new branch so the change
can be integrated, tested, enhanced, and merged down to trunk in a
controlled fashion.
A contributor agreement is not strictly necessary to submit a patch or bundle,
but without a contributor agreement on file, your contribution will be
used for reference only: it will not be applied to the code. This
may delay acceptance of your contribution.
Your contribution might not be accepted even if you do have
a contributor agreement on file. Please do not take this personally
or as an affront to your coding ability. Sometimes contributions are rejected
because they seem to be taking the project in a direction that the
architect does not want to go. In other cases, there might be an alternative
implementation of the same feature being prepared separately.
<h2>3.0 Check-in Privileges</h2>
Check-in privileges are granted on a case-by-case basis. Your chances
of getting check-in privileges are much improved if you have a history
of submitting quality patches and/or making thoughtful posts on
[https://fossil-scm.org/forum | the forum].
A signed contributor agreement is, of course, a prerequisite for check-in
privileges.</p>
Contributors are asked to make all non-trivial changes on a branch. The
Fossil Architect (Richard Hipp) will merge changes onto the trunk.</p>
Contributors are required to follow the
[./checkin.wiki | pre-checkin checklist] prior to every check-in to
the Fossil self-hosting repository. This checklist is short and succinct
and should only require a few seconds to follow. Contributors
should print out a copy of the pre-checkin checklist and keep
it on a note card beside their workstations for quick reference.
Contributors should review the
[./style.wiki | Coding Style Guidelines] and mimic the coding style
used through the rest of the Fossil source code. Your code should
blend in. A third-party reader should be unable to distinguish your
code from any other code in the source corpus.
<h2>4.0 Testing</h2>
Fossil's [../test/release-checklist.wiki | release checklist] is of
primary benefit to the project leader, followed by him at release time,
but contributors are encouraged to run through its steps when making
major changes, since if the change doesn't pass this checklist, it won't
be included in the next release.
<h2>5.0 UI and Documentation Language</h2>
The Fossil project uses American English in its web interface and
documentation. Until there is some provision for translating the UI and
docs into other languages and dialects, we ask that you do not commit
changes that conflict with this.
We aren't opposed to such a project, but it would be a huge amount of
work, which no one's stepped up to do yet. Not only is each individual
translation a large ongoing job its own right, there is no
infrastructure for it yet, so the first few translations will be harder
than any future translation built on that infrastructure.
More immediately, we're likely to reject, revert, or rework commits that
use other English dialects. One example that comes up occasionally is
"artefact" versus "artifact." The UI and docs use the American English
spelling pervasively, so you have poor options if you insist on
"artefact:"
* attempt to slip one-off changes by your peers
* attempt to change all American English usages to Commonwealth English
* make the Fossil UI and docs translatable, then contribute a
Commonwealth English translation
Only the latter is likely to succeed.

# Fossil CSS Tips and Tricks
Many aspects of Fossil's appearance can be customized by
[customizing the site skin](customskin.md). This document
details certain specific CSS tweaks which users have asked
about via the forums.
This is a "living document" - please feel free to suggest
additions via [the Fossil forum](https://fossil-scm.org/forum/).
This document is *not* an introduction to CSS - the web is
full of tutorials on that topic. It covers only the specifics
of customizing certain CSS-based behaviors in a Fossil UI. That said...
## Is it Really `!important`?
By and large, CSS's `!important` qualifier is not needed when
customizing Fossil's CSS. On occasion, however, particular styles may
be set directly on DOM elements when Fossil generates its HTML, and
such cases require the use of `!important` to override them.
<!-- ============================================================ -->
# Main UI CSS
## Number of Columns in `/dir` View
The width of columns on the [`/dir` page](/dir) is calculated
dynamically as the page is generated, to attempt to fit the widest
name in a given directory. The number of columns is determined
automatically by CSS. To modify the number of columns and/or the entry width:
```css
div.columns {
columns: WIDTH COLUMN_COUNT !important;
/* Examples:
columns: 20ex 3 !important
columns: auto auto !important
*/
}
/* The default rule uses div.columns, but it can also be selected using: */
div.columns.files { ... }
```
The `!important` qualifier is required here because the style values are dynamically
calculated and applied when the HTML is emitted.
The file list itself can be further customized via:
```css
div.columns > ul {
...
}
ul.browser {
...
}
```
<!-- ============================================================ -->
# Forum-specific CSS
## Limiting Display Length of Long Posts
Excessively long posts can make scrolling through threads problematic,
especially on mobile devices. The amount of a post which is visible can
be configured using:
```css
div.forumPostBody {
max-height: 25em; /* change to the preferred maximum effective height */
overflow: auto; /* tells the browser to add scrollbars as needed */
}
```

Notes On Diff Formatting
========================
There are two main kinds of diff display for the web interface:
unified and side-by-side. Both displays are implemented using
a <table>. The unified diff is a 4-column table, and the
side-by-side diff is a 5-column table. In a page like /info that
might show multiple file diffs, each file diff is in a separate
<table>. For side-by-side diffs, a small amount of Javascript
code is used to resize the text columns so that they fill the screen
width and to keep horizontal scrollbars in sync.
For the unified diff, the basic structure
is like this:
> ~~~~
<table class='diff udiff'>
<tr>
<td class='diffln difflnl'><pre>
Line numbers for the left-hand file
</pre></td>
<td class='diffln difflnr'><pre>
Line numbers for the right-hand file
</pre></td>
<td class='diffsep'><pre>
Change marks. "+" or "=" or nothing
</pre></td>
<td class='difftxt difftxtu'><pre>
The text
</pre></td>
</tr>
</table>
~~~~
The structure for a side-by-side diff follows the
same basic pattern, though with 5 columns instead of
4, and slightly different class names:
> ~~~~
<table class='diff splitdiff'>
<tr>
<td class='diffln difflnl'><pre>
Line numbers for the left-hand file
</pre></td>
<td class='difftxt difftxtl'><pre>
The text for the left side
</pre></td>
<td class='diffsep'><pre>
Change marks. "+" or "=" or nothing
</pre></td>
<td class='diffln difflnr'><pre>
Line numbers for the right-hand file
</pre></td>
<td class='difftxt difftxtr'><pre>
The text on the right-hand side
</pre></td>
</tr>
</table>
~~~~
The outer <table> always has class "diff". The "diffu" class
is added for unified diffs and the "splitdiff" class is added for
side-by-side diffs.
All line-number columns have the "diffln" class. They also always
have one of "difflnl" or "difflnr" depending on whether they hold
line numbers for the left or right files, respectively.
Text is always kept in a separate column so that it can be scraped
and copied by the user. All text columns have the "difftxt" class.
One additional class "difftxtu", "difftxtl", or "difftxtr" is added
depending on if the text is for a unified diff, the left column of
a side-by-side diff, or the right column of a side-by-side diff.
The content of all columns is a single <pre> that contains the
appropriate diff-text for that column. Scrolling is done on the
<pre> element.
Within text columns, highlighting is done with <del> and
<ins> markup. All text on a line that contains an isert or
delete is surrounded by <ins>...</ins> or
<del>..</del>. Within that line, specific characters
of text that specifically inserted deleted have an additional
layer of <ins> or <del> markup. Thus CSS like the
following is appropriate:
> ~~~~
td.difftxt ins {
background-color: #dafbe1; /* Light green for the whole line */
text-decoration: none;
}
td.difftxt ins > ins {
background-color: #a0e4b2; /* Dark green for specific characters that change */
text-decoration: none;
}
~~~~
In a side-by-side diff, if an interior <ins> or <del> that mark
specific characters that change correspond to a delete/insert on the other
side, they they have the "edit" class tag. (ex: <ins class='edit'>
or <del class='edit'>). Some skins choose to paint these "modified"
regions blue:
> ~~~~
td.difftxt ins > ins.edit {
background-color: #c0c0ff; /* Blue for "modified" text region */
text-decoration: none;
}
~~~~
Line number text also has <ins> and <del> tags for lines which
are pure insert or pure delete. But the tags do not nest for line numbers.

<title>Customizing The Ticket System</title>
<h2>Introduction</h2>
This guide will explain how to add the "assigned_to" and "submitted_by" fields
to the ticket system in Fossil, as well as making the system more useful. You
must have "admin" access to the repository to implement these instructions.
<h2>First modify the TICKET table</h2>
Click on the "Admin" menu, then "Tickets", then "Table". After the other fields
and before the final ")", insert:
<pre>
,
assigned_to TEXT,
opened_by TEXT
</pre>
And "Apply Changes". You have just added two more fields to the ticket
database! NOTE: I won't tell you to "Apply Changes" after each step from here
on out. Now, how do you use these fields?
<h2>Next add assignees</h2>
Back to the "Tickets" admin page, and click "Common". Add something like this:
<pre>
set assigned_choices {
unassigned
tom
dick
harriet
}
</pre>
Obviously, choose names corresponding to the logins on your system. The
'unassigned' entry is important, as it prevents you from having a NULL in that
field (which causes problems later when editing).
<h2>Now modify the 'new ticket' page</h2>
Back to the "Tickets" admin page, and click "New Ticket Page". This is a little
more tricky. Edit the top part:
<verbatim>
if {[info exists submit]} {
set status Open
set opened_by $login
set assigned_to "unassigned"
submit_ticket
}
</verbatim>
Note the "set opened_by" bit -- that will automatically set the "opened_by"
field to the login name of the bug reporter. Now, skip to the part with "EMail"
and modify it like so:
<verbatim>
<th1>enable_output expr { "$login" eq "anonymous"}</th1>
<tr>
<td align="right">
EMail:
<input type="text" name="private_contact" value="$<private_contact>" size="30">
</td>
<td>
<u>Not publicly visible</u>. Used by developers to contact you with questions.
</td>
</tr>
<th1>enable_output 1</th1>
</verbatim>
This bit of code will get rid of the "email" field entry for logged-in users.
Since we know the user's information, we don't have to ask for it. NOTE: it
might be good to automatically scoop up the user's email and put it here.
You might also want to enable people to actually assign the ticket to a specific
person during creation. For this to work, you need to add the code
for "assigned_to" as shown below under the heading "Modify the 'edit ticket' page".
This will give you an additional combobox where you can choose a person during
ticket creation.
<h2>Modify the 'view ticket' page</h2>
Look for the text "Contact:" (about halfway through). Then insert these lines
after the closing tr tag and before the "enable_output" line:
<verbatim>
<tr>
<td align="right">Assigned to:</td><td bgcolor="#d0d0d0">
$<assigned_to>
</td>
<td align="right">Opened by:</td><td bgcolor="#d0d0d0">
$<opened_by>
</td>
</tr>
</verbatim>
This will add a row which displays these two fields, in the event the user has
<a href="./caps/ref.html#w">ticket "edit" capability</a>.
<h2>Modify the 'edit ticket' page</h2>
Before the "Severity:" line, add this:
<verbatim>
<tr>
<td align="right">Assigned to:</td>
<td>
<th1>combobox assigned_to $assigned_choices 1</th1>
</td>
</tr>
</verbatim>
That will give you a drop-down list of assignees. The first argument to the TH1
command 'combobox' is the database field which the combobox is associated to.
The next argument is the list of choices you want to show in the combobox (and
that you specified in the second step above.) The last argument should be 1 for
a true combobox (see the <a href="th1.md#combobox">TH1 documentation</a> for
details).
Now, similar to the previous
section, look for "Contact:" and add this:
<verbatim>
<tr>
<td align="right">Reported by:</td>
<td>
<input type="text" name="opened_by" size="40" value="$<opened_by>">
</td>
</tr>
</verbatim>
<h2>What next?</h2>
Now you can add custom reports which select based on the person to whom the
ticket is assigned. For example, an "Assigned to me" report could be:
<verbatim>
SELECT
CASE WHEN status IN ('Open','Verified') THEN '#f2dcdc'
WHEN status='Review' THEN '#e8e8e8'
WHEN status='Fixed' THEN '#cfe8bd'
WHEN status='Tested' THEN '#bde5d6'
WHEN status='Deferred' THEN '#cacae5'
ELSE '#c8c8c8' END AS 'bgcolor',
substr(tkt_uuid,1,10) AS '#',
datetime(tkt_mtime) AS 'mtime',
type,
status,
subsystem,
title
FROM ticket
WHERE assigned_to=user()
</verbatim>

# Customizing the Timeline Graph
Beginning with version 1.33, Fossil gives users and skin authors significantly
more control over the look and feel of the timeline graph.
## <a id="basic-style"></a>Basic Style Options
Fossil includes several options for changing the graph's style without having
to delve into CSS. These can be found in the details.txt file of your skin or
under Admin/Skins/Details in the web UI.
* **`timeline-arrowheads`**
Set this to `0` to hide arrowheads on primary child lines.
* **`timeline-circle-nodes`**
Set this to `1` to make check-in nodes circular instead of square.
* **`timeline-color-graph-lines`**
Set this to `1` to colorize primary child lines.
* **`white-foreground`**
Set this to `1` if your skin uses white (or any light color) text.
This tells Fossil to generate darker background colors for branches.
## <a id="adv-style"></a>Advanced Styling
If the above options aren't enough for you, it's time to get your hands dirty
with CSS. To get started, I recommend first copying all the [graph-related CSS
rules](#default-css) to your stylesheet. Then it's simply a matter of making
the necessary changes to achieve the look you want. So, next, let's look at the
various graph elements and what purpose they serve.
Each element used to construct the timeline graph falls into one of two
categories: visible elements and positioning elements. We'll start with the
latter, less obvious type.
## <a id="pos-elems"></a>Positioning Elements
These elements aren't intended to be seen. They're only used to help position
the graph and its visible elements.
* <a id="tl-canvas"></a>**`.tl-canvas`**
Set the left and right margins on this class to give the desired amount
of space between the graph and its adjacent columns in the timeline.
**Additional Classes**
* `.sel`: See [`.tl-node`](#tl-node) for more information.
* <a id="tl-rail"></a>**`.tl-rail`**
Think of rails as invisible vertical lines on which check-in nodes are
placed. The more simultaneous branches in a graph, the more rails required
to draw it. Setting the `width` property on this class determines the
maximum spacing between rails. This spacing is automatically reduced as
the number of rails increases. If you change the `width` of `.tl-node`
elements, you'll probably need to change this value, too.
* <a id="tl-mergeoffset"></a>**`.tl-mergeoffset`**
A merge line often runs vertically right beside a primary child line. This
class's `width` property specifies the maximum spacing between the two.
Setting this value to `0` will eliminate the vertical merge lines.
Instead, the merge arrow will extend directly off the primary child line.
As with rail spacing, this is also adjusted automatically as needed.
* <a id="tl-nodemark"></a>**`.tl-nodemark`**
In the timeline table, the second cell in each check-in row contains an
invisible div with this class. These divs are used to determine the
vertical position of the nodes. By setting the `margin-top` property,
you can adjust this position.
## <a id="vis-elems"></a>Visible Elements
These are the elements you can actually see on the timeline graph: the nodes,
arrows, and lines. Each of these elements may also have additional classes
attached to them, depending on their context.
* <a id="tl-node"></a>**`.tl-node`**
A node exists for each check-in in the timeline.
**Additional Classes**
* `.leaf`: Specifies that the check-in is a leaf (i.e. that it has no
children in the same branch).
* `.merge`: Specifies that the check-in contains a merge.
* `.sel`: When the user clicks a node to designate it as the beginning
of a diff, this class is added to both the node itself and the
[`.tl-canvas`](#tl-canvas) element. The class is removed from both
elements when the node is clicked again.
* <a id="tl-arrow"></a>**`.tl-arrow`**
Arrows point from parent nodes to their children. Technically, this
class is just for the arrowhead. The rest of the arrow is composed
of [`.tl-line`](#tl-line) elements.
There are six additional classes that are used to distinguish the different
types of arrows. However, only these combinations are valid:
* `.u`: Up arrow that points to a child from its primary parent.
* `.u.sm`: Smaller up arrow, used when there is limited space between
parent and child nodes.
* `.merge.l` or `.merge.r`: Merge arrow pointing either to the left or
right.
* `.warp`: A timewarped arrow (always points to the right), used when a
misconfigured clock makes a check-in appear to have occurred before its
parent ([example](https://www.sqlite.org/src/timeline?c=2010-09-29&nd)).
* <a id="tl-line"></a>**`.tl-line`**
Along with arrows, lines connect parent and child nodes. Line thickness is
determined by the `width` property, regardless of whether the line is
horizontal or vertical. You can also use borders to create special line
styles. Here's a CSS snippet for making dotted merge lines:
.tl-line.merge {
width: 0;
background: transparent;
border: 0 dotted #000;
}
.tl-line.merge.h {
border-top-width: 1px;
}
.tl-line.merge.v {
border-left-width: 1px;
}
**Additional Classes**
* `.merge`: A merge line.
* `.h` or `.v`: Horizontal or vertical.
* `.warp`: A timewarped line.

# Skinning the Fossil Web Interface
The Fossil web interface comes with a pre-configured look and feel. The default
look and feel works fine in many situations. However, you may want to change
the look and feel (the "skin") of Fossil to better suite your own individual tastes.
This document provides background information to aid you in that task.
## <a id="builtin"></a>Built-in Skins
Fossil comes with [multiple built-in skins](/skins). If the default skin does not
suite your tastes, perhaps one of the other built-in skins will work better.
If nothing else, the built-in skins can serve as examples or templates that
you can use to develop your own custom skin.
The sources to these built-ins can
be found in the Fossil source tree under the skins/ folder. The
[skins/](/dir?ci=trunk&name=skins)
folder contains a separate subfolder for each built-in skin, with each
subfolders holding at least these five files:
* css.txt
* details.txt
* footer.txt
* header.txt
* js.txt
Try out the built-in skins by using the --skin option on the
[fossil ui](/help?cmd=ui) or [fossil server](/help?cmd=server) commands.
## <a id="sharing"></a>Sharing Skins
The skin of a repository is not part of the versioned state and does not
"push" or "pull" like checked-in files. The skin is local to the
repository. However, skins can be shared between repositories using
the [fossil config](/help?cmd=configuration) command.
The "fossil config push skin" command will send the local skin to a remote
repository and the "fossil config pull skin" command will import a skin
from a remote repository. The "fossil config export skin FILENAME"
will export the skin for a repository into a file FILENAME. This file
can then be imported into a different repository using the
"fossil config import FILENAME" command. Unlike "push" and "pull",
the "export" and "import" commands are able to move skins between
repositories for different projects. So, for example, if you have a
group of related repositories, you can develop a skin for one of them,
then get a consistent look across all the repositories by exporting
the skin from the first repository and importing into all the others.
The file generated by "fossil config export" could be checked into
one of your repositories and versioned, if desired. This will not
automatically change the skin when looking backwards in time, but it
will provide an historical record of what the skin used to be and
allow the historical look of the repositories to be recreated if
necessary.
When cloning a repository, the skin of the new repository is initialized to
the skin of the repository from which it was cloned.
# Structure Of A Fossil Web Page
Every HTML page generated by Fossil has the same basic structure:
| Fossil-Generated HTML Header |
| Skin Header |
| Fossil-Generated Content |
| Skin Footer |
| Fossil-Generated HTML Footer |
By default, Fossil starts every generated HTML page with this:
<html>
<head>
<base href="...">
<meta http-equiv="Content-Security-Policy" content="....">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>....</title>
<link rel="stylesheet" href="..." type="text/css">
</head>
<body class="FEATURE">
Fossil used to require a static version of this in every skin’s Header
area, but over time, we have found good cause to generate multiple
elements at runtime.
One such is the `FEATURE` element, being either the top-level HTTP
request routing element (e.g. `doc`) or an aggregate feature class that
groups multiple routes under a single name. A prime example is `forum`,
which groups the `/forummain`, `/forumpost`, and `/forume2` routes,
allowing per-feature CSS. For instance, to style `<blockquote>` tags
specially for forum posts written in Markdown, leaving all other block
quotes alone, you could say:
body.forum div.markdown blockquote {
margin-left: 10px;
}
You can [override this generated HTML header](#override) by including a
“`<body>`†tag somewhere in the Header area of the skin, but it is
almost always best to limit a custom skin’s Header section to something
like this:
<div class="sidebar" id="version-2.24">Prior to Fossil 2.24, we used
generic `<div>` elements to mark up these sections of the header, but we
switched to these semantic tag names to give browser accessibility
features more freedom to do intelligent things with the page content.
Those who made custom skins based on the old way of doing things will
need to track this change when upgrading, else the corresponding CSS
will mistarget the page header elements. Also, if you’re using Fossil’s
chat feature, failing to track this change will cause it to miscalculate
the message area size, resulting in double scrollbars. Simply diffing
your custom header in the skin editor against the stock version should
be sufficient to show what you need to change.</div>
<header>
...
</header>
<nav class="mainmenu" title="Main Menu">
...
</nav>
<nav id="hbdrop" class="hbdrop" title="sitemap"></nav>
See the stock skins’ headers for ideas of what to put in place of the
ellipses.
The Fossil-generated Content section immediately follows this Header.
It will look like this:
<div class="content">
... Fossil-generated content here ...
</div>
After the Content is the custom Skin Footer section which should
follow this template:
<footer>
... skin-specific stuff here ...
</footer>
As with the `<header>` change called out above, this, too, is a breaking
change in Fossil 2.24.
Finally, Fossil always adds its own footer (unless overridden)
to close out the generated HTML:
</body>
</html>
## <a id="mainmenu"></a>Changing the Main Menu Contents
The actual text content of the skin’s main menu is not
part of the skin proper if you’re using one of the stock skins.
If you look at the Header section of the skin, you’ll find a
`<div class="mainmenu">` element whose contents are set by a short
[TH1](./th1.md) script from the contents of the **Main Menu** section of
the Setup → Configuration screen.
This feature allows the main menu contents to stay the same across
different skins, so you no longer have to reapply menu customizations
when trying different skins.
See the [`capexpr`](./th1.md#capexpr) section of the TH1 docs for help
on interpreting the default contents of this block.
## <a id="override"></a>Overriding the HTML Header and Footer
Notice that the `<html>`, `<head>`, and opening `<body>`
elements at the beginning of the document,
and the closing `</body>` and `</html>` elements at the end are automatically
generated by Fossil. This is recommended.
However, for maximum design flexibility, Fossil allows those elements to be
supplied as part of the configurable Skin Header and Skin Footer.
If the Skin Header contains the text "`<body`", then Fossil assumes that
the Skin Header and Skin Footer will handle all of the `<html>`,
`<head>`, and `<body>` text itself, and the Fossil-generated header and
footer will be blank.
When overriding the HTML Header in this way, you will probably want to use some
of the [TH1 variables documented below](#vars) such as `$stylesheet_url`
to avoid hand-writing code that Fossil can generate for you.
# Designing, Debugging, and Installing A Custom Skin
It is possible to develop a new skin from scratch. But a better and easier
approach is to use one of the existing built-in skins as a baseline and
make incremental modifications, testing after each step, to obtain the
desired result.
The skin is controlled by five files:
<dl>
<dt><b>css.txt</b></dt>
<dd>The css.txt file is the text of the CSS for Fossil.
Fossil might add additional CSS elements after
the css.txt file, if it sees that the css.txt omits some
CSS components that Fossil needs. But for the most part,
the content of the css.txt is the CSS for the page.</dd>
<dt><b>details.txt</b><dt>
<dd>The details.txt file is short list of settings that control
the look and feel, mostly of the timeline. The default
details.txt file looks like this:
<pre>
pikchr-background: ""
pikchr-fontscale: ""
pikchr-foreground: ""
pikchr-scale: ""
timeline-arrowheads: 1
timeline-circle-nodes: 1
timeline-color-graph-lines: 1
white-foreground: 0
</pre>
The three "timeline-" settings in details.txt control the appearance
of certain aspects of the timeline graph. The number on the
right is a boolean - "1" to activate the feature and "0" to
disable it. The "white-foreground:" setting should be set to
"1" if the page color has light-color text on a darker background,
and "0" if the page has dark text on a light-colored background.
If the "pikchr-foreground" setting
is defined and is not an empty string then it specifies a
foreground color to use for [pikchr diagrams](./pikchr.md). The
default pikchr foreground color is black, or white if the
"white-foreground" boolean is set. The "pikchr-background"
settings does the same for the pikchr diagram background color.
If the "pikchr-fontscale" and "pikchr-scale" values are not
empty strings, then they should be floating point values (close
to 1.0) that specify relative scaling of the fonts in pikchr
diagrams and other elements of the diagrams, respectively.
</dd>
<dt><b>footer.txt</b> and <b>header.txt</b></dt>
<dd>The footer.txt and header.txt files contain the Skin Footer
and Skin Header respectively. Of these, the Skin Header is
the most important, as it contains the markup used to generate
the banner and menu bar for each page.
Both the footer.txt and header.txt file are
[processed using TH1](#headfoot) prior to being output as
part of the overall web page.</dd>
<dt><b>js.txt</b></dt>
<dd>The js.txt file is optional. It is intended to be javascript.
The complete text of this javascript might be inserted into
the Skin Footer, after being processed using TH1, using
code like the following in the "footer.txt" file:
<pre>
<script nonce="$nonce">
<th1>styleScript</th1>
</script>
</pre>
The js.txt file was originally used to insert javascript
that controls the hamburger menu in the default skin. More
recently, the javascript for the hamburger menu was moved into
a separate built-in file. Skins that use the hamburger menu
typically cause the javascript to be loaded by including the
following TH1 code in the "header.txt" file:
<pre>
<th1>builtin_request_js hbmenu.js</th1>
</pre>
The difference between `styleScript` and `builtin_request_js`
is that the `styleScript` command interprets the file
using TH1 and injects the content directly into the output
stream, whereas the `builtin_request_js` command inserts the
Javascript verbatim and does so at some unspecified future time
down inside the Fossil-generated footer.
You can use either
approach in custom skins that you create.
Note that the "js.txt" file is *not* automatically inserted into
the generate HTML for a page. You, the skin designer, must
cause the javascript to be inserted by issuing appropriate
TH1 commands in the "header.txt" or "footer.txt" files.</dd>
</dl>
Developing a new skin is simply a matter of creating appropriate
versions of these five control files.
### Skin Development Using The Web Interface
Users with admin privileges can use the Admin/Skin configuration page
on the web interface to develop a new skin. The development of a new
skin occurs without disrupting the existing skin. So you can work on
a new skin for a Fossil instance while the existing skin is still in
active use.
The new skin is a "draft" skin. You initialize one of 9 draft skins
to either the current skin or to one of the built-in skins. Then
use forms to edit the 5 control files described above. The new
skin can be tested after each edit. Finally, once the new skin is
working as desired, the draft skin is "published" and becomes the
new live skin that most users see.
### Skin Development Using A Local Text Editor
An alternative approach is to copy the five control files for your
baseline skin into a temporary working directory (here called
"./newskin") and then launch the [fossil ui](/help?cmd=ui) command
with the "--skin ./newskin" option. If the argument to the --skin
option contains a "/" character, then the five control files are
read out of the directory named. You can then edit the control
files in the ./newskin folder using you favorite text editor, and
press "Reload" on your browser to see the effects.
### Disabling The Web Browser Cache During Development
Fossil is aggressive about asking the web browser to cache
resources. While developing a new skin, it is often helpful to
put your web browser into developer mode and disable the cache.
If you fail to do this, then you might make some change to your skin
under development and press "Reload" only to find that the display
did not change. After you have finished work your skin, the
caches should synchronize with your new design and you can reactivate
your web browser's cache and take it out of developer mode.
## <a id="headfoot"></a>Header and Footer Processing
The `header.txt` and `footer.txt` control files of a skin are the HTML text
of the Skin Header and Skin Footer, except that before being inserted
into the output stream, the text is run through a
[TH1 interpreter](./th1.md) that might adjust the text as follows:
* All text within <th1>...</th1> is omitted from the
output and is instead run as a TH1 script. That TH1
script has the opportunity to insert new text in place of itself,
or to inhibit or enable the output of subsequent text.
* Text of the form "$NAME" or "$<NAME>" is replaced with
the value of the TH1 variable NAME.
For example, first few lines of a typical Skin Header will look
like this:
<div class="header">
<div class="title"><h1>$<project_name></h1>$<title>/div>
After variables are substituted by TH1, that will look more like this:
<div class="header">
<div class="title"><h1>Project Name</h1>Page Title</div>
As you can see, two TH1 variable substitutions were done.
The same TH1 interpreter is used for both the header and the footer
and for all scripts contained within them both. Hence, any global
TH1 variables that are set by the header are available to the footer.
## <a id="menu"></a>Customizing the ≡ Hamburger Menu
The menu bar of the default skin has an entry to open a drop-down menu with
additional navigation links, represented by the ≡ button (hence the name
"hamburger menu"). The Javascript logic to open and close the hamburger menu
when the button is clicked is usually handled by a script named
"hbmenu.js" that is one of the [built-in resource files](/test-builtin-files)
that are part of Fossil.
The ≡ button for the hamburger menu is added to the menu bar by the following
TH1 commands in the `header.txt` file, right before the menu bar links:
html "<a id='hbbtn' href='$home/sitemap'>☰</a>"
builtin_request_js hbmenu.js
The hamburger button can be repositioned between the other menu links (but the
drop-down menu is always left-aligned with the menu bar), or it can be removed
by deleting the above statements. The "html" statement inserts the appropriate
`<a>` for the hamburger menu button (some skins require something slightly
different - for example the ardoise skins wants "`<li><a>`"). The
"builtin_request_js hbmenu.js" asks Fossil to include the "hbmenu.js"
resource files in the Fossil-generated footer.
The hbmenu.js script requires
the following `<div>` element somewhere in your header, in which to build
the hamburger menu.
<div id='hbdrop'></div>
Out of the box, the contents of the panel is populated with the [Site
Map](/sitemap), but only if the panel does not already contain any HTML
elements (that is, not just comments, plain text or non-presentational white
space). So the hamburger menu can be customized by replacing the empty `<div
id='hbdrop'></div>` element with a menu structure knitted according to the
following template:
<div id="hbdrop" data-anim-ms="400">
<ul class="columns" style="column-width: 20em; column-count: auto">
<!-- NEW GROUP WITH HEADING LINK -->
<li>
<a href="$home$index_page">Link: Home</a>
<ul>
<li><a href="$home/timeline">Link: Timeline</a></li>
<li><a href="$home/dir?ci=tip">Link: File List</a></li>
</ul>
</li>
<!-- NEW GROUP WITH HEADING TEXT -->
<li>
Heading Text
<ul>
<li><a href="$home/doc/trunk/www/customskin.md">Link: Theming</a></li>
<li><a href="$home/doc/trunk/www/th1.md">Link: TH1 Scripts</a></li>
</ul>
</li>
<!-- NEXT GROUP GOES HERE -->
</ul>
</div>
The custom `data-anim-ms` attribute can be added to the panel element to direct
the Javascript logic to override the default menu animation duration of 400 ms.
A faster animation duration of 80-200 ms may be preferred for smaller menus. The
animation is disabled by setting the attribute to `"0"`.
## <a id="vars"></a>TH1 Variables
Before expanding the TH1 within the header and footer, Fossil first
initializes a number of TH1 variables to values that depend on
repository settings and the specific page being generated.
* **`project_name`** - The project_name variable is filled with the
name of the project as configured under the Admin/Configuration
menu.
* **`project_description`** - The project_description variable is
filled with the description of the project as configured under
the Admin/Configuration menu.
* **`title`** - The title variable holds the title of the page being
generated.
The title variable is special in that it is deleted after
the header script runs and before the footer script. This is
necessary to avoid a conflict with a variable by the same name used
in my ticket-screen scripts.
* **`baseurl`** - The root of the URL namespace for this server.
* **`secureurl`** - The same as $baseurl except that if the scheme is
"http:" it is changed to "https:"
* **`home`** - The $baseurl without the scheme and hostname. For example,
if the $baseurl is "http://projectX.com/cgi-bin/fossil" then the
$home will be just "/cgi-bin/fossil".
* **`index_page`** - The landing page URI as
specified by the Admin/Configuration setup page.
* **`current_page`** - The name of the page currently being processed,
without the leading "/" and without query parameters.
Examples: "timeline", "doc/trunk/README.txt", "wiki".
* **`csrf_token`** - A token used to prevent cross-site request forgery.
* **`default_csp`** - [Fossil’s default CSP](./defcsp.md) unless
[overridden by custom TH1 code](./defcsp.md#th1). Useful within
the skin for inserting the CSP into a `<meta>` tag within [a
custom `<head>` element](#headfoot).
* **`nonce`** - The value of the cryptographic nonce for the request
being processed.
* **`release_version`** - The release version of Fossil. Ex: "1.31"
* **`manifest_version`** - A prefix on the check-in hash of the
specific version of fossil that is running. Ex: "\[47bb6432a1\]"
* **`manifest_date`** - The date of the source-code check-in for the
version of fossil that is running.
* **`compiler_name`** - The name and version of the compiler used to
build the fossil executable.
* **`login`** - This variable only exists if the user has logged in.
The value is the username of the user.
* **`stylesheet_url`** - A URL for the internal style-sheet maintained
by Fossil.
* **`logo_image_url`** - A URL for the logo image for this project, as
configured on the Admin/Logo page.
* **`background_image_url`** - A URL for a background image for this
project, as configured on the Admin/Logo page.
All of the above are variables in the sense that either the header or the
footer is free to change or erase them. But they should probably be treated
as constants. New predefined values are likely to be added in future
releases of Fossil.
## <a id="procedure"></a>Suggested Skin Customization Procedure
Developers are free, of course, to develop new skins using any method they
want, but the following is a technique that has worked well in the past and
can serve as a starting point for future work:
1. Select a built-in skin that is closest to the desired look. Make
copies of the css, footer, and header into files name "css.txt",
"details.txt",
"footer.txt", and "header.txt" in some temporary directory.
If the Fossil source code is available, then these three files can
be copied directly out of one of the subdirectories under skins. If
sources are not easily at hand, then a copy/paste out of the
CSS, footer, and header editing screens under the Admin menu will
work just as well. The important point is that the three files
be named exactly "css.txt", "footer.txt", and "header.txt" and that
they all be in the same directory.
2. Run the [fossil ui](/help?cmd=ui) command with an extra
option "--skin SKINDIR" where SKINDIR is the name of the directory
in which the three txt files were stored in step 1. This will bring
up the Fossil website using the tree files in SKINDIR.
3. Edit the *.txt files in SKINDIR. After making each small change,
press Reload on the web browser to see the effect of that change.
Iterate until the desired look is achieved.
4. Copy/paste the resulting css.txt, details.txt,
header.txt, and footer.txt files
into the CSS, details, header, and footer configuration screens
under the Admin/Skins menu.

# The Default Content Security Policy (CSP)
When Fossil’s web interface generates an HTML page, it normally includes
a [Content Security Policy][csp] (CSP) in the `<head>`. The CSP specifies
allowed sources for external resources such as images,
CSS, javascript, and so forth.
The purpose of CSP is to provide an extra layer of protection against
[cross-site scripting][xss] (XSS) and code injection
attacks. Compatible web browsers will not use external resources unless
they are specifically allowed by the CSP, which dramatically reduces
the attack surface of the application.
Fossil does not rely on CSP for security.
A Fossil server should be secure from attack even without CSP.
Fossil includes built-in server-side content filtering logic.
For example, Fossil purposely breaks `<script>` tags when it finds
them in Markdown and Fossil Wiki documents. And the Fossil build
process scans the source code for potential injection vulnerabilities
and refuses to compile if any problems are found.
However, CSP provides an additional layer of defense against undetected
bugs that might lead to a vulnerability.
## The Default Restrictions
The default CSP used by Fossil is as follows:
<pre>
default-src 'self' data:;
script-src 'self' 'nonce-$nonce';
style-src 'self' 'unsafe-inline';
img-src * data:;
</pre>
The default is recommended for most installations. However,
the site administrators can overwrite this default CSP using the
[default-csp setting](/help?cmd=default-csp). For example,
CSP restrictions can be completely disabled by setting the default-csp to:
default-src *;
The following sections detail the maining of the default CSP setting.
### <a id="base"></a> default-src 'self' data:
This policy means mixed-origin content isn’t allowed, so you can’t refer
to resources on other web domains. Browsers will ignore a link like the
one in the following Markdown under our default CSP:
If you look in the browser’s developer console, you should see a CSP
error when attempting to render such a page.
The default policy does allow inline `data:` URIs, which means you could
[data-encode][de] your image content and put it inline within the
document:
That method is best used for fairly small resources. Large `data:` URIs
are hard to read and edit. There are secondary problems as well: if you
put a large image into a Fossil forum post this way, anyone subscribed
to email alerts will get a copy of the raw URI text, which can amount to
pages and pages of [ugly Base64-encoded text][b64].
For inline images within [embedded documentation][ed], it suffices to
store the referred-to files in the repo and then refer to them using
repo-relative URLs:
This avoids bloating the doc text with `data:` URI blobs:
There are many other cases, [covered below](#serving).
[b64]: https://en.wikipedia.org/wiki/Base64
[svr]: ./server/
### <a id="img"></a> img-src * data:
It was not always thus, but after careful consideration, we’ve chosen to
leave the source of inline images unrestricted by default in Fossil.
This allows you to pull them in from remote systems, to pull them from
within the Fossil repository itself, or to use `data:` URIs.
If you are certain all images come from only within the repository, you
can close off certain risks — tracking pixels, broken image format
decoders, system dialog box spoofing, etc. — by changing this to
“`img-src 'self'`†possibly followed by “`data:`†if you will also use
`data:` URIs.
### <a id="style"></a> style-src 'self' 'unsafe-inline'
This policy allows CSS information to come from separate files hosted
under the Fossil repo server’s Internet domain. It also allows inline CSS
`<style>` tags within the document text.
The `'unsafe-inline'` declaration allows CSS within individual HTML
elements:
<p style="margin-left: 4em">Indented text.</p>
As the "`unsafe-`" prefix on the name implies, the `'unsafe-inline'`
feature is suboptimal for security. However, there are
a few places in the Fossil-generated HTML that benefit from this
flexibility and the work-arounds are verbose and difficult to maintain.
Furthermore, the harm that can be done with style injections is far
less than the harm possible with injected javascript. And so the
`'unsafe-inline'` compromise is accepted for now, though it might
go away in some future release of Fossil.
### <a id="script"></a> script-src 'self' 'nonce-%s'
This policy disables in-line JavaScript and only allows `<script>`
elements if the `<script>` includes a `nonce` attribute that matches the
one declared by the CSP. That nonce is a large random number, unique for
each HTTP page generated by Fossil, so an attacker cannot guess the
value, so the browser will ignore an attacker’s injected JavaScript.
That nonce can only come from one of three sources, all of which should
be protected at the system administration level on the Fossil server:
* **Fossil server C code:** All code paths in Fossil that emit
`<script>` elements include the `nonce` attribute. There are several
cases, such as the “JavaScript†section of a [custom skin][cs].
That text is currently inserted into each HTML page generated by
Fossil,¹ which means it needs to include a `nonce` attribute to
allow it to run under this default CSP. We consider JavaScript
emitted via these paths to be safe because it’s audited by the
Fossil developers. We assume that you got your Fossil server’s code
from a trustworthy source and that an attacker cannot replace your
Fossil server binary.
* **TH1 code:** The Fossil TH1 interpreter pre-defines the
[`$nonce` variable](./th1.md#nonce) for use in [custom skins][cs]. For
example, some of the stock skins that ship with Fossil include a
wall clock feature up in the corner that updates once a minute.
These paths are safe in the default Fossil configuration because
only the [all-powerful Setup user][su] can write TH1 code that
executes in the server’s running context.
There is, however, [a default-disabled path](#xss) to beware of,
covered in the next section.
* **[CGI server extensions][ext]:** Fossil exports the nonce to the
CGI in the `FOSSIL_NONCE` environment variable, which it can then
use in `<script>` elements it generates. Because these extensions
can only be installed by the Fossil server’s system administrator,
this path is also considered safe.
[ext]: ./serverext.wiki
[su]: ./caps/admin-v-setup.md#apsu
#### <a id="xss"></a>Cross-Site Scripting via Ordinary User Capabilities
We’re so restrictive about how we treat JavaScript because it can lead
to difficult-to-avoid scripting attacks. If we used the same CSP for
`<script>` tags [as for `<style>` tags](#style), anyone with check-in
rights on your repository could add a JavaScript file to your repository
and then refer to it from other content added to the site. Since
JavaScript code can access any data from any URI served under its same
Internet domain, and many Fossil users host multiple Fossil repositories
under a single Internet domain, such a CSP would only be safe if all of
those repositories are trusted equally.
Consider [the Chisel hosting service](http://chiselapp.com/), which
offers free Fossil repository hosting to anyone on the Internet, all
served under the same `http://chiselapp.com/user/$NAME/$REPO` URL
scheme. Any one of those hundreds of repositories could trick you into
visiting their repository home page, set to [an HTML-formatted embedded
doc page][hfed] via Admin → Configuration → Index Page, with this
content:
<script src="/doc/trunk/bad.js"></script>
That script can then do anything allowed in JavaScript to *any other*
Chisel repository your browser can access. The possibilities for mischief
are *vast*. For just one example, if you have login cookies on four
different Chisel repositories, your attacker could harvest the login
cookies for all of them through this path if we allowed Fossil to serve
JavaScript files under the same CSP policy as we do for CSS files.
This is why the default configuration of Fossil has no way for [embedded
docs][ed], [wiki articles][wiki], [tickets][tkt], [forum posts][fp], or
[tech notes][tn] to automatically insert a nonce into the page content.
This is all user-provided content, which could link to user-provided
JavaScript via check-in rights, effectively giving all such users a
capability that is usually reserved to the repository’s administrator.
The default-disabled [TH1 documents feature][edtf] is the only known
path around this restriction. If you are serving a Fossil repository
that has any user you do not implicitly trust to a level that you would
willingly run any JavaScript code they’ve provided, blind, you **must
not** give the `--with-th1-docs` option when configuring Fossil, because
that allows substitution of the [pre-defined `$nonce` TH1
variable](./th1.md#nonce) into [HTML-formatted embedded docs][hfed]:
<script src="/doc/trunk/bad.js" nonce="$nonce"></script>
Even with this feature enabled, you cannot put `<script>` tags into
Fossil Wiki or Markdown-formatted content, because our HTML generators
for those formats purposely strip or disable such tags in the output.
Therefore, if you trust those users with check-in rights to provide
JavaScript but not those allowed to file tickets, append to wiki
articles, etc., you might justify enabling TH1 docs on your repository,
since the only way to create or modify HTML-formatted embedded docs is
through check-ins.

## <a id="serving"></a>Serving Files Within the Limits
There are several ways to serve files within the above restrictions,
avoiding the need to [override the default CSP](#override). In
decreasing order of simplicity and preference:
1. Within [embedded documentation][ed] (only!) you can refer to files
stored in the repo using document-relative file URLs:
2. Relative file URLs don’t work from [wiki articles][wiki],
[tickets][tkt], [forum posts][fp], or [tech notes][tn], but you can
still refer to them inside the repo with [`/doc`][du] or
[`/raw`][ru] URLs:
<img src="/raw/logo.png" style="float: right; margin-left: 2em">
3. Store the files as [unversioned content][uv], referred to using
[`/uv`][uu] URLs instead:
4. Use the [optional CGI server extensions feature](./serverext.wiki)
to serve such content via `/ext` URLs.
5. Put Fossil behind a [front-end proxy server][svr] as a virtual
subdirectory within the site, so that our default CSP’s “self†rules
match static file routes on that same site. For instance, your repo
might be at `https://example.com/code`, allowing documents in that
repo to refer to:
* images as `/image/foo.png`
* JavaScript files as `/js/bar.js`
* CSS style sheets as `/style/qux.css`
Although those files are all outside the Fossil repo at `/code`,
keep in mind that it is the browser’s notion of “self†that matters
here, not Fossil’s. All resources come from the same Internet
domain, so the browser cannot distinguish Fossil-provided content
from static content served directly by the proxy server.
This method opens up many other potential benefits, such as
[TLS encryption][tls], high-performance tuning via custom HTTP
headers, integration with other web technologies like PHP, etc.
You might wonder why we rank in-repo content as most preferred above. It
is because the first two options are the only ones that cause such
resources to be included in an initial clone or in subsequent repo
syncs. The methods further down the list have a number of undesirable
properties:
1. Relative links to out-of-repo files break in `fossil ui` when run on
a clone.
2. Absolute links back to the public repo instance solve that:
...but using them breaks some types of failover and load-balancing
schemes, because it creates a [single point of failure][spof].
3. Absolute links fail when one’s purpose in using a clone is to
recover from the loss of a project web site by standing that clone
up [as a server][svr] elsewhere. You probably forgot to copy such
external resources in the backup copies, so that when the main repo
site disappears, so do those files.
Unversioned content is in the middle of the first list above — between
fully-external content and fully in-repo content — because it isn’t
included in a clone unless you give the `--unversioned` flag. If you
then want updates to the unversioned content to be included in syncs,
you have to give the same flag to [a `sync` command](/help?cmd=sync).
There is no equivalent with other commands such as `up` and `pull`, so
you must then remember to give `fossil uv` commands when necessary to
pull new unversioned content down.
Thus our recommendation that you refer to in-repo resources exclusively.

## <a id="override"></a>Overriding the Default CSP
If you wish to relax the default CSP’s restrictions or to tighten them
further, there are multiple ways to accomplish that.
The following methods are listed in top-down order to give the simplest
and most straightforward method first. Further methods dig down deeper
into the stack, which is helpful to understand even if you end up using
a higher-level method.
### <a id="cspsetting"></a>The `default-csp` Setting
If the [`default-csp` setting](/help?cmd=default-csp) is defined and is
not an empty string, its value is injected into the page using
[TH1](./th1.md) via one or more of the methods below, depending on the
skin you’re using and local configuration.
Changing this setting is the easiest way to set a nonstandard CSP on
your site.
Because a blank setting tells Fossil to use its hard-coded default CSP,
you have to say something like the following to get a repository without
content security policy restrictions:
$ fossil set -R /path/to/served/repo.fossil default-csp 'default-src *'
We recommend that instead of using the command line to change this
setting that you do it via the repository’s web interface, in
Admin → Settings. Write your CSP rules in the edit box marked
"`default-csp`". Do not add hard newlines in that box: the setting needs
to be on a single long line. Beware that changes take effect
immediately, so be careful with your edits: you could end up locking
yourself out of the repository with certain CSP changes!
There are a few reasons why changing this setting via the command line
is inadvisable, except for very short settings like the example above:
1. You have to be sure to set it on the repository where you want the
CSP to apply. Changing this setting on your local clone doesn’t
affect the remote repo you cloned from, which is most likely where
you want the CSP restrictions.
2. For more complicated CSPs, the quoting rules for your shell and the
CSP syntax may interact, making it difficult or impossible to set
your desired CSP via the command line. Setting it via the web UI
doesn’t have this problem.
### <a id="th1"></a>TH1 Setup Hook
Fossil sets [the TH1 variable `$default_csp`][thvar] from the
`default-csp` setting and uses *that* to inject the value into generated
HTML pages in its stock configuration.
This means that another way you can override this value is to use
the [`th1-setup` hook script](./th1-hooks.md), which runs before TH1
processing happens during skin processing:
$ fossil set th1-setup "set default_csp {default-src 'self'}"
After [the above](#admin-ui), this is the cleanest method.
[thvar]: ./customskin.md#vars
### <a id="csrc"></a>Fossil C Source Code
When you do neither of the above things, Fossil uses
[a hard-coded default](/info?ln=527-530&name=65a555d0d4fb846b).
We tell you about this not to suggest that you hack the Fossil C source
code to change the CSP but simply to document the next step before we
move down-stack.
### <a id="header"></a>Skin Header
[In the normal case](./customskin.md#override), Fossil injects the CSP
retrieved by one of the above methods into the header of all HTML
documents it generates:
```HTML
<head>...
<meta http-equiv="Content-Security-Policy" content="...">
...
```
Fossil skips this when you’re using a custom skin *and* its
[Header section](./customskin.md#headfoot) includes a `<body>` tag. This
is because prior to Fossil 2.5, the Header for a custom skin normally
contained everything from the opening `<html>` tag through the leading
`<body>` tag. From that version onward, Fossil now generates that header
when possible, so that the skin’s Header normally provides only the
opening tags of the document body, rather than the HTML header.
When we added CSP support in Fossil 2.7, we made use of that mechanism
to inject the CSP into the generated HTML document header.
For backwards compatibility, Fossil skips this when the skin’s Header
includes a `<body>` tag. Fossil takes that as a hint that it’s dealing
with a skin made in the pre-Fossil-2.5 days and doesn’t try to blindly
override it.
The problem then is that you may be a Fossil user from the days before
Fossil 2.5, and you may be using a custom skin. This includes users who
selected one of the stock skins, since for the purposes of this section,
there is no difference between the cases. If you go into Admin → Skins →
Header and find a `<body>` tag, none of the above will apply to your
repo since Fossil will not be injecting its CSP into your pages.
If you selected one of the stock skins (e.g. Khaki) prior to upgrading
to Fossil 2.5+ and didn’t make any changes to it since that time, you
can take the simplest option, which is to simply revert to the stock
version of the skin, so your pages will have the CSP injected, at which
point this document will begin describing what Fossil does with that
repo.
If you’re using a customized version of one of the stock skins, the
skinning mechanism has a diff feature to make it easier to fold your
local changes into the stock version.
If you’re using a fully customized skin, we recommend replicating the
method that [the Bootstrap skin uses][dcinj].² Alone among the stock
Fossil skins, Bootstrap still does old-style Header processing,
providing the entire HTML header and the start of the document body.
We do *not* recommend injecting an explicit `Content-Security-Policy`
meta tag into a header to override Fossil’s default CSP. That means you
have to edit the skin every time you want to change the CSP. Use the TH1
`$default_csp` variable like the Bootstrap skin does so you can use one
of the methods above with your custom skin, so the CSP can vary
independently of the skin.
[dcinj]: /info?ln=7&name=bef080a6929a3e6f
### <a id="fep"></a>Front-End Proxy
If your Fossil repo is behind some sort of HTTP [front-end proxy][svr],
the [preferred method][pmcsp] for setting the CSP is via a custom HTTP
header, which most HTTP reverse proxy programs allow.
Beware that if you have a CSP set via both the HTTP and HTML headers
that the two CSPs [merge](https://stackoverflow.com/a/51153816/142454),
taking the most restrictive elements of each CSP. If you wish the proxy
layer’s setting to completely override Fossil’s setting, you will need
to combine that with one of the methods above to either remove the
Fossil-provided CSP or to make Fossil provide a no-restrictions CSP
which the front-end proxy can then tighten down.

------------
**Asides and Digressions:**
1. Fossil might someday switch to serving the “JavaScript†section of a
custom skin as a virtual text file, allowing it to be cached by the
browser, reducing page load times.
2. The stock Bootstrap skin *did* provide redundant CSP text from
Fossil 2.7 through Fossil 2.9, so setting the CSP via the higher
level methods did not work with that skin. We fixed this in Fossil
2.10, but if you selected the Bootstrap skin prior to that, you’re
now running on a *copy* of it stored in your repo settings table, so
the change to the stock version of the skin won’t affect that repo
automatically. You will have to either merge the diffs in with your
local changes or revert to the stock version of the skin.

This document describes an optional feature not enabled by default.</div> This article describes "delta manifests," a special-case form of checkin manifest which is intended to take up far less space than a normal checkin manifest, in particular for repositories with many files. We'll see, however, that the space savings, if indeed there are any, come with some caveats. This article assumes that the reader is at least moderately familiar with Fossil's [artifact file format](./fileformat.wiki), in particular the structure of checkin manifests, and it won't make much sense to readers unfamiliar with that topic. # Background and Motivation of Delta Manifests A checkin manifest includes a list of every file in that checkin. A moderately-sized project can easily have a thousand files, and every checkin manifest will include those thousand files. As of this writing Fossil's own checkins contain 989 files and the manifests are 80kb each. Thus a checkin which changes only 2 bytes of source code ostensibly costs another 80kb of storage for the manifest for that change. Delta manifests were conceived as a mechanism to help combat that storage overhead. # Makeup of a Delta Manifest A delta manifest is structured like a normal manifest (called a "baseline" manifest) except that it has *two types of parents*: the P-card which is part of (nearly) every manifest and a so-called baseline (denoted by a B-card). The P-card tells us which artifact(s) is/are the parents for purposes of the SCM version DAG. The B-card tells us which manifest to use as a basis for this delta. The B-card need not be, and often is not, the same as the P-card. Here's an example: ``` B c04ce8aaf1170966c6f8abcce8b57e72a0fa2b81 C Minor\sdoc\supdates... D 2021-03-11T18:56:24.686 F bindings/s2/shell_extend.c 6d8354c693120a48cfe4798812cd24499be174b2 <15 F-cards snipped for brevity> F src/repo.c 2f224cb0e59ccd90ba89c597e40b8e8d87506638 P 61d3e64e6fb1a93d4a7b0182e4c6b94d178d66d9 R a84ec2e8e1eb37ff0d94cac262795e23 U stephan Z 536e6d26dd8dbe2779d9e5f52a15518e ``` The B-card names another manifest, by its unique ID, the same way that a P-card does. A manifest may have multiple P-card parents (the second and subsequent ones denoting merge parents) but B-cards always refer to exactly one parent. What unambiguously distinguishes this as a delta is the existence of the B-card. All deltas have a B-card and no other type of artifact has one. What also, but not unambiguously, distinguishes it as a delta is that it has only 17 F-cards, whereas a baseline manifest in that same repository has (as of this writing) 291 F-cards. In this particular case, the delta manifest is 1363 bytes, compared to 20627 bytes for the next checkin - a baseline manifest. That's a significant saving in F-cards, especially if a repository contains thousands of files. That savings, however, comes with caveats which we'll address below. Trivia regarding the B-card: - The B-card always refers to a baseline manifest, not another delta. - Deltas may not chain with another delta, but any number of deltas may have the same B-card. It is quite common for a series of delta manifest checkins, each of which derives (in the P-card sense) from the one before it, to have the same B-card. A delta manifest is functionally identical to a normal manifest except that it has a B-card and how it records F-cards. Namely, it only records F-cards which have changed at some point between this delta and the version represented by the delta's B-card. This recording of F-card *differences* also means that delta manifests, unlike normal manifests, have to explicitly record deleted F-cards. Baseline manifests do not record deletions. Instead, they include a list of every file which is part of that checkin. Deltas, however, record the differences between their own version and a baseline version, and thus have to record deletions. They do this by including F-cards which have only a file name and no hash. Iterating over F-cards in a manifest is something several important internal parts of Fossil have to do. Iterating over a baseline manifest, e.g. when performing a checkout, is straightforward: simply walk through the list in the order the cards are listed. A delta, however, introduces a significant wrinkle to that process. In short, when iterating over a delta's F-cards, code has to compare the delta's list to the baseline's list. If the delta has an entry the parent does not have, or which is a newer entry for the same file, the delta's entry is used. If the delta is missing an entry which the baseline has, the baseline's entry is used. When a deletion F-card is discovered in the delta (recall that baselines do not record deletions), iteration over that card is skipped - the internal algorithms which iterate over F-cards never report deletions to the code iterating over those cards. The reason for that is consistency: only deltas record file deletions, but the fact that it's a delta is an internal detail, not something which higher-level code should concern itself with. If higher-level iteration code were shown file deletions, they would effectively be dealing with a leaky abstraction and special-case handling which only applies to delta manifests. The F-card iteration API hides such details from its users (other Fossil-internal APIs). # When does Fossil Create Deltas? By default, Fossil never creates delta manifests. It can be told to do so using the `--delta` flag to the [`commit` command](/help/commit). (Before doing so in your own repositories, please read the section below about the caveats!) When a given repository gets a delta manifest for the first time, Fossil records that fact in the repository's `config` table with an entry named `seen-delta-manifest`. If, in later sessions, Fossil sees that that setting has a true value, it will *consider* creating delta manifests by default. Conversely, the [`forbid-delta-manifests` repository config setting](/help/forbid-delta-manifests) may be used to force Fossil to *never* create deltas. That setting will propagate to other repository clones via the sync process, to try to ensure that no clone introduces a delta manifests. We'll cover reasons why one might want to use that setting later on. After creating a delta manifest during the commit process, Fossil examines the size of the delta. If, in Fossil's opinion, the space savings are not significant enough to warrant the delta's own overhead, it will discard the delta and create a new baseline manifest instead. (The heuristic it uses for that purpose is tucked away in Fossil's checkin algorithm.) # Caveats Delta manifests may appear, on the surface, to be a great way to save a few bytes of repository space. There are, however, caveats... ## Space Savings? Though deltas were conceived as a way to save storage space, that benefit is *not truly achieved* because... When a manifest is created, Fossil stores its parent version as a [fossil delta](./delta_format.wiki) (as opposed to a delta manifest) which succinctly descibes the differences between the parent and its new child. This form of compression is extremely space-efficient and can reduce the real storage space requirements of a manifest from tens or hundreds of kilobytes down to a kilobyte or less for checkins which modify only a few files. As an example, as of this writing, Fossil's [tip checkin baseline manifest](/artifact/decd537016bf) is 80252 bytes (uncompressed), and the delta-compressed baseline manifest of the [previous checkin](/artifact/2f7c93f49c0e) is stored as a mere 726 bytes of Fossil-delta'd data (not counting the z-lib compression which gets applied on top of that). In this case, the tip version modified 7 files compared to its parent version. Thus delta manifests do not *actually* save much storage space. They save *some*, in particular in the tip checkin version: Fossil delta-compresses *older* versions of checkins against the child versions, as opposed to delta-compressing the children against the parents. The reason is to speed up access for the most common case - the latest version. Thus tip-version delta manifests are more storage-space efficient than tip-version baseline manifests. Once the next version is committed, though, and Fossil deltification is applied to those manifests, that difference in space efficiency shrinks tremendously, often to the point of insignificance. We can observe the Fossil-delta compression savings using a bit of 3rd-party code which can extract Fossil-format blobs both with and without applying their deltas: ``` $ f-acat tip > A # tip version's manifest $ f-acat prev --raw > B # previous manifest in its raw fossil-deltified form $ f-acat prev > C # previous manifest fossil-undelta'd $ ls -la A B C -rw-rw-r-- 1 user user 80252 Mar 12 07:09 A # tip -rw-rw-r-- 1 user user 726 Mar 12 07:09 B # previous: delta'd -rw-rw-r-- 1 user user 80256 Mar 12 07:09 C # previous: undelta'd ``` For comparison's sake, when looking at a separate repository which uses delta manifests, a delta-compressed delta manifest takes up approximately the same space as a delta-compressed baseline manifest (to within 10 bytes for the test samples). i.e. delta manifests may not save any storage space except for the tip version! (*Surprise!*) In terms of RAM costs, deltas usually cost more memory than baseline manifests. The reason is because traversing a delta requires having not only that delta in memory, but also its baseline version. Delta manifests are seldom used in ways which do not require also loading their baselines. Thus Fossil internally requires two manifest objects for most operations with a delta manifest, whereas a baseline has but one. The difference in RAM cost is directly proportional to the size of the delta manifest. ## Manifests as Proof of Code Integrity Delta manifests have at least one more notable caveat, this one arguably more significant than an apparent lack of space savings: they're useless for purposes of publishing a manifest which downstream clients can use to verify the integrity of their copy of the software. Consider this use case: [the SQLite project](https://sqlite.org) publishes source code to many thousands of downstream consumers, many of whom would like to be able to verify that the copy they have downloaded is actually the copy published by the project. This is easily achieved by providing a copy of the downloaded version's manifest, as it contains a hash of every single file the project published and the manifest itself has a well-known hash and is cryptographically tamper-proof. It's mathematically extremely improbable for a malicious party to modify such a manifest and re-publish it as an "official" one, as the various hashes (F-cards, R-card, Z-card, *and* the hash of the manifest itself) would not line up. A collision-based attack would have to defeat *all four of those hashes*, which is practically impossible to do. Thus a Fossil checkin manifest can be used to provide strong assurances that a given copy of the software has not been tampered with since being exported by Fossil. *However*, that use case is *only possible with baseline manifests*. A delta manifest is *essentially useless* for that purpose. The algorithm for traversing F-cards of a delta manifest is not trivial for arbitrary clients to reproduce, e.g. using a shell script. While it *could* be done in any higher-level programming language (or some truly unsightly shell code), it would be an onerous burden on downstream consumers and would not be without risks of having bugs which invalidate the strong guarantees provided by the manifest. It's worth noting that the core Fossil project repository does not use delta manifests, at least in part for the same reason the SQLite project does not: the ability to provide a manifest which clients can easily use to verify the integrity of the code they've downloaded. The [`forbid-delta-manifests` config setting](/help/forbid-delta-manifests) is used to ensure that none are introduced into the repository beyond the few which were introduced solely for testing purposes. |

It is targeted at developers working on either <a href="index.wiki">fossil</a> itself, or on tools compatible with it. The exact format of the generated byte-sequences, while in general not necessary to understand encoder operation, can be found in the companion specification titled "<a href="delta_format.wiki">Fossil Delta Format</a>". </p> <p>The algorithm is inspired by <a href="http://samba.anu.edu.au/rsync/">rsync</a>.</p> <h2 id="argresparam">1.0 Arguments, Results, and Parameters</h2> <p>The encoder takes two byte-sequences as input, the "original", and the "target", and returns a single byte-sequence containing the "delta" which transforms the original into the target upon its application.</p> <p>Note that the data of a "byte-sequence" includes its length, i.e. the number of bytes contained in the sequence.</p> <p>The algorithm has one parameter named "NHASH", the size of the "sliding window" for the "rolling hash", in bytes.

<title>Fossil Delta Format</title>
<h1>1.0 Overview</h1>
Fossil achieves efficient storage and low-bandwidth synchronization
through the use of delta-compression. Instead of storing
or transmitting the complete content of an artifact, Fossil stores or
transmits only the changes relative to a related artifact.
This document describes the delta-encoding format used by Fossil.
The intended audience is developers working on either
<a href="index.wiki">Fossil</a> itself, or on tools compatible with
Fossil. Understanding of this document is <em>not</em> required for
ordinary users of Fossil. This document is an implementation detail.
This document only describes the delta file format. A
[./delta_encoder_algorithm.wiki|separate document] describes one possible
algorithm for generating deltas in this format.
<h2>1.1 Sample Software And Analysis Tools</h2>
The core routines used to generate and apply deltas in this format
are contained in the [../src/delta.c|delta.c] source file. Interface
logic, including "test-*" commands to directly manipulate deltas are
contained in the [../src/deltacmd.c|deltacmd.c] source file. SQL functions
to create, apply, and analyze deltas are implemented by code in the
[../src/deltafunc.c|deltafunc.c] source file.
The following command-line tools are available to create and apply
deltas and to test the delta logic:
* [/help?cmd=test-delta|fossil test-delta] → Run self-tests of
the delta logic
* [/help?cmd=test-delta-create|fossil test-delta-create X Y] → compute
a delta that converts file X into file Y. Output that delta.
* [/help?cmd=test-delta-apply|fossil test-delta-apply X D] → apply
delta D to input file X and output the result.
* [/help?cmd=test-delta-analyze|fossil test-delta-analyze X Y] → compute
and delta that converts file X into file Y but instead of writing the
delta to output, write performance information about the delta.
When running the [/help?cmd=sqlite3|fossil sql] command to get an
interactive SQL session connected to the repository, the following
additional SQL functions are provided:
* <b>delta_create(</b><i>X</i><b>,</b><i>Y</i><b>)</b> →
Compute a data that carries blob X into blob Y and return that delta
as a blob.
* <b>delta_apply(</b><i>X</i><b>,</b><i>D</i><b>)</b> →
Apply delta D to input blob X return a new blob which is the result.
* <b>delta_output_size(</b><i>D</i>)</b> →
Return the size of the output that would result from applying delta D.
* <b>delta_parse(</b><i>D</i>)</b> → This is a table-valued function
that returns one row for the header, for the trailer, and for each segment
in delta D.
<h1 id="structure">2.0 Structure</h1>
<verbatim type="pikchr">
leftmargin = 0.1
box height 50% "Header"
box same "Segments"
box same "Trailer"
</verbatim>
A delta consists of three parts, a "header", a "trailer", and a
"segment-list" between them.
Both header and trailer provide information about the target
helping the decoder, and the segment-list describes how the target can
be constructed from the original.
<h2 id="header">2.1 Header</h2>
<verbatim type="pikchr">
leftmargin = 0.1
box height 50% "Size"
box same "\"\\n\""
</verbatim>
The header consists of a single number followed by a newline
character (ASCII 0x0a). The number is the length of the target in
bytes.
This means that, given a delta, the decoder can compute the size of
the target (and allocate any necessary memory based on that) by simply
reading the first line of the delta and decoding the number found
there. In other words, before it has to decode everything else.
<h2 id="trailer">2.2 Trailer</h2>
<verbatim type="pikchr">
leftmargin = 0.1
box height 50% "Checksum"
box same "\";\""
</verbatim>
The trailer consists of a single number followed by a semicolon (ASCII
0x3b). This number is a checksum of the target and can be used by a
decoder to verify that the delta applied correctly, reconstructing the
target from the original.
The checksum is computed by treating the target as a series of
32-bit integer numbers (MSB first), and summing these up, modulo
2^32-1. A target whose length is not a multiple of 4 is padded with
0-bytes (ASCII 0x00) at the end.
By putting this information at the end of the delta a decoder has
it available immediately after the target has been reconstructed
fully.
<h2 id="slist">2.3 Segment-List</h2>
<verbatim type="pikchr">
leftmargin = 0.1
PART1: [
B1: box height 50% width 15% ""
B2: box same ""

</verbatim>
The segment-list of a delta describes how to create the target from
the original by a combination of inserting literal byte-sequences and
copying ranges of bytes from the original. This is where the
compression takes place, by encoding the large common parts of
original and target in small copy instructions.
The target is constructed from beginning to end, with the data
generated by each instruction appended after the data of all previous
instructions, with no gaps.
<h3 id="insertlit">2.3.1 Insert Literal</h3>
A literal is specified by two elements, the size of the literal in
bytes, and the bytes of the literal itself.
<verbatim type="pikchr">
leftmargin = 0.1
box "Length" height 50%
box "\":\"" same
box "Bytes" same
</verbatim>
The length is written first, followed by a colon character (ASCII
0x3a), followed by the bytes of the literal.
<h3 id="copyrange">2.3.2 Copy Range</h3>
A range to copy is specified by two numbers, the offset of the
first byte in the original to copy, and the size of the range, in
bytes. The size zero is special, its usage indicates that the range
extends to the end of the original.
<verbatim type="pikchr">
leftmargin = 0.1
box "Length" height 50%
box "\"@\"" same
box "Offset" same
box "\",\"" same
</verbatim>
The length is written first, followed by an "at" character (ASCII
0x40), then the offset, followed by a comma (ASCII 0x2c).
<h1 id="intcoding">3.0 Encoding of integers</h1>
The format currently handles only 32 bit integer numbers. They are
written base-64 encoded, MSB first, and without leading
"0"-characters, except if they are significant (i.e. 0 => "0").
The base-64 encoding uses one character for each 6 bits of
the integer to be encoded. The encoding characters are:
<pre>
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz~
</pre>
The least significant 6 bits of the integer are encoded by
the first character, followed by
the next 6 bits, and so on until all non-zero bits of the integer
are encoded. The minimum number of encoding characters is used.
Note that for integers less than 10, the base-64 coding is a
ASCII decimal rendering of the number itself.

<h1>1.0 Fossil Support For Embedded Documentation</h1>
The fossil web interface supports embedded documentation using
the "/doc" page. To access embedded documentation, one points
a web browser to a fossil URL of the following form:
<pre>
<i><baseurl></i><big><b>/doc/</b></big><i><version></i><big><b>/</b></big><i><filename></i>
</pre>
The <i><baseurl></i> is the main URL used to access the fossil web server.
For example, the <i><baseurl></i> for the fossil project itself is
[https://fossil-scm.org/home].
If you launch the web server using the "[/help?cmd=ui|fossil ui]" command line,
then the <i><baseurl></i> is usually
<b>http://localhost:8080/</b>.
The <i><version></i> is the
[./checkin_names.wiki|name of a check-in]
that contains the embedded document. This might be a hash prefix for
the check-in, or it might be the name of a branch or tag, or it might
be a timestamp. See the prior link
for more possibilities and examples.
The <i id="ckout"><version></i> can
also be the special identifier "<b>ckout</b>".
The "<b>ckout</b>" keywords means to
pull the documentation file from the local source tree on disk, not
from the any check-in. The "<b>ckout</b>" keyword
only works when you start your server using the
"[/help?cmd=server|fossil server]" or "[/help?cmd=ui|fossil ui]"
commands. The "/doc/ckout" URL is intended to show a preview of
the documentation you are currently editing but have not yet checked in.
The original designed purpose of the "ckout" feature is to allow the
user to preview local changes to documentation before committing the
change. This is an important facility, since unlike other document
languages like HTML, there is still a lot of variation among rendering
engines for Fossil's markup languages, Markdown and Fossil Wiki. Your
changes may look fine in your whizzy GUI Markdown editor, but what
actually matters is how <i>Fossil</i> will interpret your Markdown text.
Therefore, you should always preview your edits before committing them.
To help make "ckout" easier to use, the "[/help?cmd=ui|fossil ui]"
command has the "--ckout-alias NAME" option that makes NAME an
alias for "ckout". If you are editing a collection of documents
that have hardcoded links to one another in the form of
"/doc/trunk/...", for example, you can test your changes by
running "fossil ui --ckout-alias trunk" and all of the links will
point to your uncommitted edits rather than to the latest trunk
check-in.
Finally, the <i><filename></i> element of the URL is the
pathname of the documentation file relative to the root of the source
tree.
The mimetype (and thus the rendering) of documentation files is
determined by the file suffix. Fossil currently understands
[/mimetype_list|many different file suffixes],
including all the popular ones such as ".css", ".gif", ".htm",
".html", ".jpg", ".jpeg", ".png", and ".txt".
Documentation files whose names end in ".wiki" use the
[/wiki_rules | fossil wiki markup] -
a safe subset of HTML together with some wiki rules for paragraph
breaks, lists, and hyperlinks.
Documentation files ending in ".md" or ".markdown" use the
[/md_rules | Markdown markup language].
Documentation files ending in ".txt" are plain text.
Wiki, markdown, and plain text documentation files
are rendered with the standard fossil header and footer added.
Most other mimetypes are delivered directly to the requesting
web browser without interpretation, additions, or changes.
<h2 id="html">1.1 HTML Rendering With Fossil Headers And Footers</h2>
Files with the mimetype "text/html" (the .html or .htm suffix) are
usually rendered directly to the browser without interpretation.
However, if the file begins with a <div> element like this:
<b><div class='fossil-doc' data-title='<i>Title Text</i>'></b>
Then the standard Fossil header and footer are added to the document
prior to being displayed. The "class='fossil-doc'" attribute is
required for this to occur. The "data-title='...'" attribute is
optional, but if it is present the text will become the title displayed
in the Fossil header. An example of this can be seen in Fossil
Documentation Index www/permutedindex.html:
* [/file/www/permutedindex.html?txt|source text for <b>www/permutedindex.html</b>]
* [/doc/trunk/www/permutedindex.html|<b>www/permutedindex.html</b> rendered as HTML]
Beware that such HTML files render in the same browser security context
as all other embedded documentation served from Fossil; they are not
fully-independent web pages. One practical consequence of this is that
embedded <tt><script></tt> tags will cause a
[https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP | Content
Security Policy] error in your browser with the default CSP as served by
Fossil. See the documentation on [./customskin.md#headfoot | Header and
Footer Processing] and [./defcsp.md | The Default CSP].
<h1>2.0 Server-Side Text Substitution</h1>
Fossil can do a few types of substitution of server-side information
into the embedded document.
<h2>2.1 "$ROOT" In HTML and Markdown Hyperlinks</h2>
Hyperlinks in Markdown and HTML embedded documents can reference
the root of the Fossil repository using the special text "$ROOT"
at the beginning of a URL. For example, a Markdown hyperlink to
the Markdown formatting rules might be
written in the embedded document like this:
<verbatim>
[Markdown formatting rules]($ROOT/wiki_rules)
</verbatim>
Depending on how the how the Fossil server is configured, that hyperlink
might be renderer like one of the following:
<verbatim>
<a href="/wiki_rules">Wiki formatting rule</a>
<a href="/cgi-bin/fossil/wiki_rules">Wiki formatting rules</a>
</verbatim>
So, in other words, the "$ROOT" text is converted into whatever
the "<baseurl>" is for the document.
This substitution works for HTML and Markdown documents.
It does not work for Wiki embedded documents, since with
Wiki you can just begin a URL with "/" and it automatically knows
to prepend the $ROOT.
<h2>2.2 "$CURRENT" In "/doc/" Hyperlinks</h2>
Similarly, URLs of the form "/doc/$CURRENT/..." have the check-in
hash of the check-in currently being viewed substituted in place of
the "$CURRENT" text. This feature, in combination with the "$ROOT"
substitution above, allows an absolute path to be used for hyperlinks.
For example, if an embedded document documented wanted to reference
some other document in a separate file named "www/otherdoc.md",
it could use a URL like this:
<verbatim>
[Other Document]($ROOT/doc/$CURRENT/www/otherdoc.md)
</verbatim>
As with "$ROOT", this substitution only works for Markdown and HTML
documents. For Wiki documents, you would need to use a relative URL.
<h2 id="th1">2.3 TH1 Documents</h2>
Enabling TH1 document support requires the following:
* Configure the build with the <code>--with-th1-docs</code> flag.
* Enable the <code>th1-docs</code> setting, which is only available
after building with <code>--with-th1-docs</code>.
* Affected files must have a <code>.th1</code> file extension.
* The code to run must be embedded in blocks of
<code><th1>...</th1></code>.
Fossil will substitute the value of [./th1.md | TH1 expressions]
within the <code><th1>...</th1></code> blocks into
the output HTML.
Since TH1 is a full scripting language, this feature essential grants
the ability to execute code on the server to anyone with check-in
privilege for the project.
This is a security risk that needs to be carefully managed.
The feature is off by default.
Administrators should understand and carefully assess the risks
before enabling the use of TH1 within embedded documentation.
<h1>3.0 Examples</h1>
This file that you are currently reading is an example of
embedded documentation. The name of this file in the fossil
source tree is "<b>www/embeddeddoc.wiki</b>".
You are perhaps looking at this
file using the URL:
<pre>[https://fossil-scm.org/home/doc/trunk/www/embeddeddoc.wiki]</pre>
The first part of this path, the "[https://fossil-scm.org/home]",
is the base URL. You might have originally typed:
[https://fossil-scm.org/]. The web server at the fossil-scm.org
site automatically redirects such links by appending "home". The
"home" file on fossil-scm.org is really a [./server/any/cgi.md|CGI script]
which runs the fossil web service in CGI mode.
The "home" CGI script looks like this:
<pre>
#!/usr/bin/fossil
repository: /fossil/fossil.fossil
</pre>
This is one of the many ways to set up a
<a href="./server/">Fossil server</a>.
The "<b>/trunk/</b>" part of the URL tells fossil to use
the documentation files from the most recent trunk check-in.
If you wanted to see an historical version of this document,
you could substitute the name of a check-in for "<b>/trunk/</b>".
For example, to see the version of this document associated with
check-in [9be1b00392], simply replace the "<b>/trunk/</b>" with
"<b>/9be1b00392/</b>". You can also substitute the symbolic name
for a particular version or branch. For example, you might
replace "<b>/trunk/</b>" with "<b>/experimental/</b>" to get the latest
version of this document in the "experimental" branch. The symbolic name
can also be a date and time string in any of the following formats:</p>
<ul>
<li> <i>YYYY-MM-DD</i>
<li> <i>YYYY-MM-DD<b>T</b>HH:MM</i>
<li> <i>YYYY-MM-DD<b>T</b>HH:MM:SS</i>
</ul>
When the symbolic name is a date and time, fossil shows the version
of the document that was most recently checked in as of the date
and time specified. So, for example, to see what the fossil website
looked like at the beginning of 2010, enter:
<pre><a href="https://fossil-scm.org/home/doc/2010-01-01/www/index.wiki">https://fossil-scm.org/home/doc/<b>2010-01-01</b>/www/index.wiki
</a></pre>
The file that encodes this document is stored in the fossil source tree under
the name "<b>www/embeddeddoc.wiki</b>" and so that name forms the
last part of the URL for this document.
As I sit writing this documentation file, I am testing my work by
running the "<b>fossil ui</b>" command line and viewing
<b>http://localhost:8080/doc/ckout/www/embeddeddoc.wiki</b> in
Firefox. I am doing this even though I have not yet checked in
the "<b>www/embeddeddoc.wiki</b>" file for the first time. Using
the special "<b>ckout</b>" version identifier on the "<b>/doc</b>" page
it is easy to make multiple changes to multiple files and see how they all
look together before committing anything to the repository.

This technical note explains the process. <h2>Building An Encryption-Enabled Fossil</h2> The SQLite Encryption Extension (SEE) is proprietary software and requires [https://sqlite.org/purchase/see|purchasing a license]. Assuming you have an SEE license, the first step of compiling Fossil to use SEE is to create an SEE-enabled version of the SQLite database source code. This alternative SQLite database source file should be called "sqlite3-see.c" and should be placed in the extsrc/ subfolder of the Fossil sources, right beside the public-domain "sqlite3.c" source file. Also make a copy of the SEE-enabled "shell.c" file, renamed as "shell-see.c", and place it in the extsrc/ subfolder beside the original "shell.c". Add the --with-see command-line option to the configuration script to enable the use of SEE on unix-like systems. <pre> ./configure --with-see; make </pre> To build for Windows using MSVC, add the "USE_SEE=1" argument to the "nmake" command line. <pre> nmake -f makefile.msc USE_SEE=1 </pre> <h2>Using Encrypted Repositories</h2> Any Fossil repositories whose filename ends with ".efossil" is taken to be an encrypted repository. Fossil will prompt for the encryption password and attempt to open the repository database using that password. Every invocation of fossil on an encrypted repository requires retyping the encryption password. To avoid excess password typing, consider using the "fossil shell" command which prompts for the password just once, then reuses it for each subsequent Fossil command entered at the prompt. On Windows, the "fossil server", "fossil ui", and "fossil shell" commands do not (currently) work on an encrypted repository. <h2>Additional Security</h2> Use the FOSSIL_SECURITY_LEVEL environment for additional protection. <pre> export FOSSIL_SECURITY_LEVEL=1 </pre> A setting of 1 or greater prevents fossil from trying to remember the previous sync password. <pre> export FOSSIL_SECURITY_LEVEL=2 </pre> A setting of 2 or greater causes all password prompts to be preceded by a random translation matrix similar to the following: <pre> abcde fghij klmno pqrst uvwyz qresw gjymu dpcoa fhkzv inlbt </pre> When entering the password, the user must substitute the letter on the second line that corresponds to the letter on the first line. Uppercase substitutes for uppercase inputs, and lowercase substitutes for lowercase inputs. Letters that are not in the translation matrix (digits, punctuation, and "x") are not modified. For example, given the translation matrix above, if the password is "pilot-9crazy-xube", then the user must type "fmpav-9ekqtb-xirw".

Environment Variables and Global Options
========================================
Fossil uses a number of environment variables and supports a number
of global options. Most of these seem to be primarily documented in
the source code, with the primary exception of `--args` which is
described in the usage text printed by running fossil with no
arguments at all.
Global Options
--------------
The following options are understood by the fossil command itself, and
are collected before any subcommand begins processing.
`--args FILENAME`: Read the file `FILENAME` and replace these two
arguments with its content. Each line of the file is assumed to be an
argument unless it starts with '-' and contains a space, in which case
it is assumed to be another flag and is treated as such. `--args
FILENAME` may be used in conjunction with any other flags.
`--case-sensitive BOOL`: Override the `case-sensitive` setting, which
can override the native preferences of the platform for case sensitive
file names: insensitive on Windows, sensitive on Unix. There are
probably odd interactions possible if you mix case sensitive and case
insensitive file systems on any single platform. This option or the
global setting should be used to force the case sensitivity to the
most sensible condition.
`--cgitrace`: Active CGI tracing.
`--chdir DIRECTORY`: Change to the named directory before processing
any commands.
`--comfmtflags NUMBER`: Specify flags that control how check-in comments
and certain other text outputs are formatted for display. The flags are
individual bits in `NUMBER`, which must be specified in base 10:
* _0_ — Uses the revised algorithm with no special handling.
* _1_ — Uses the legacy algorithm, other flags are ignored.
* _2_ — Trims leading and trailing carriage-returns and line-feeds
where they do not materially impact pre-existing formatting
(i.e. at the start of the comment string _and_ right before
line indentation).
* _4_ — Trims leading and trailing spaces where they do not materially
impact the pre-existing formatting (i.e. at the start of the
comment string _and_ right before line indentation).
* _8_ — Attempts to break lines on word boundaries while honoring the
logical line length.
* _16_ — Looks for the original comment text within the text being
printed. Upon matching, a new line will be emitted, thus
preserving more of the pre-existing formatting.
`--comment-format NUMBER`: Alias for `--comfmtflags NUMBER`.
`--errorlog ERRLOG`: Name a file to which fossil will log panics,
errors, and warnings.
`--help`: If `--help` is found anywhere on the command line, translate
the command to `fossil help cmdname` where `cmdname` is the first
argument that does not begin with a `-` character. If all arguments
start with `-`, translate to `fossil help argv[1] argv[2]...`.
`--httptrace`: (Sets `g.fHttpTrace`.) Trace outbound HTTP requests.
`--localtime`: Override the `timeline-utc` option to explicitly use
local time.
`--nocgi`: Prevent fossil from acting as a CGI by default even if the
`GATEWAY_INTERFACE` environment variable is set.
`--no-th-hook`: (Sets `g.fNoThHook`.) Override the `th1-hooks` setting
and prevent any TH1 hooks from being executed.
`--quiet`: (Sets `g.fQuiet`.) Cause fossil to suppress various messages and progress
indicators that would otherwise be printed.
`--sqltrace`: (Sets `g.SqlTrace`.) Implies `--sqlstats`. Trace certain
SQLite database activity, especially showing every SQL query
processed.
`--sqlstats`: (Sets `g.fSqlStats`.) Print a number of performance
statistics about each SQLite database used when it is closed.
`--sshtrace`: (Sets `g.fSshTrace`.)
`--ssl-identity`: The fully qualified name of the file containing the client
certificate and private key to use, in PEM format. It can be created by
concatenating the client certificate and private key files. This identity will
be presented to SSL servers to authenticate the client, in addition to the
normal password authentication.
`--systemtrace`: (Sets `g.fSystemTrace`.) Trace all commands launched
as sub processes.
`--user LOGIN`: (Sets `g.zLogin`) Also `-U LOGIN`. Set the user name
used with the repository.
`--utc`: Override the `timeline-utc` option to explicitly use
UTC time.
`--vfs VFSNAME`: Load the named VFS into SQLite.
Environment Variables
---------------------
The location of the user's account-wide [configuration database][configdb]
depends on the operating system and on the existence of various
environment variables and/or files. See the discussion of the
[configuration database location algorithm][configloc] for details.
`EDITOR`: Name the editor to use for check-in and stash comments.
Overridden by the local or global `editor` setting or the `VISUAL`
environment variable.
`FOSSIL_BREAK`: If set, an opportunity will be created to attach a
debugger to the Fossil process prior to any significant work being
performed.
`FOSSIL_FORCE_TICKET_MODERATION`: If set, *ALL* changes for tickets
will be required to go through moderation (even those performed by the
local interactive user via the command line). This can be useful for
local (or remote) testing of the moderation subsystem and its impact
on the contents and status of tickets.
`FOSSIL_FORCE_WIKI_MODERATION`: If set, *ALL* changes for wiki pages
will be required to go through moderation (even those performed by the
local interactive user via the command line). This can be useful for
local (or remote) testing of the moderation subsystem and its impact
on the contents and status of wiki pages.
`FOSSIL_HOME`: Location of [configuration database][configdb].
See the [configuration database location][configloc] description
for additional information.
`FOSSIL_USE_SEE_TEXTKEY`: If set, treat the encryption key string for
SEE as text to be hashed into the actual encryption key. This has no
effect if Fossil was not compiled with SEE support enabled.
`FOSSIL_USER`: Name of the default user account if the checkout, local
or global `default-user` setting is not present. The first environment
variable found in the environment from the list `FOSSIL_USER`, `USER`,
`LOGNAME`, and `USERNAME` is the user name. If none of those are set,
then the default user name is "root". See the discussion of Fossil
Username below for a lot more detail.
`FOSSIL_SECURITY_LEVEL`: If set to any of the values listed below,
additional measures for password security will be enabled (also see
[How To Use Encrypted Repositories][encryptedrepos.wiki]):
[encryptedrepos.wiki]: /doc/trunk/www/encryptedrepos.wiki
* _≥1_ — Do not remember passwords.
* _≥2_ — Use a scrambled matrix for password input.
`FOSSIL_TCL_PATH`: When Tcl stubs support is configured, point to a
specific file or folder containing the version of Tcl to load at run
time.
`FOSSIL_TEST_DANGEROUS_IGNORE_OPEN_CHECKOUT`: When set to the literal
value `YES_DO_IT`, the test suite will relax the constraint that some
tests may not run within an open checkout. This is subject to removal
in the future.
`FOSSIL_VFS`: Name a VFS to load into SQLite.
`GATEWAY_INTERFACE`: If present and the `--nocgi` option is not, assume
fossil is invoked from a web server as a CGI command, and act
accordingly.
`HOME`: Potential location of the [configuration database][configdb].
See the [configuration database location][configloc] description for details.
`HOMEDRIVE`, `HOMEPATH`: (Windows) Location of the `~/.fossil` file.
The first environment variable found in the environment from the list
`FOSSIL_HOME`, `LOCALAPPDATA` (Windows), `APPDATA` (Windows),
`HOMEDRIVE` and `HOMEPATH` (Windows, used together), and `HOME` is
used as the location of the `~/.fossil` file.
`HTTP_HOST`: If defined, included in error log messages.
`http_proxy`: If the global or local settings `proxy` is not set, this
is used as the default value for the `proxy` setting.
`HTTP_USER_AGENT`: If defined, included in error log messages.
`LOCALAPPDATA`: (Windows) Location of the `~/.fossil` file. The first
environment variable found in the environment from the list
`FOSSIL_HOME`, `LOCALAPPDATA` (Windows), `APPDATA` (Windows),
`HOMEDRIVE` and `HOMEPATH` (Windows, used together), and `HOME` is
used as the location of the `~/.fossil` file.
`LOGNAME`: Name of the logged in user on many Unix-like platforms.
Used as the fossil user name if `FOSSIL_USER` is not specified. See
the discussion of Fossil Username below for a lot more detail.
`PATH`: Used by most platforms to locate programs invoked without a
fully qualified name. Explicitly used by `fossil ui` on certain platforms
to choose the browser to launch.
`PATH_INFO`: If defined, included in error log messages.
`QUERY_STRING`: If defined, included in error log messages.
`REMOTE_ADDR`: If defined, included in error log messages.
`REMOTE_HOST`: Used by `fossil http` run from `stunnel` to identify
the remote host.
`REQUEST_METHOD`: If defined, included in error log messages.
`REQUEST_URI`: If defined, included in error log messages.
`SCRIPT_NAME`: If defined, included in error log messages.
`SSH_CONNECTION`: Informs CGI processing if the remote client is SSH.
`SSL_CERT_FILE`, `SSL_CERT_DIR`: Override the [`ssl-ca-location`]
(/help?cmd=ssl-ca-location) setting.
`SQLITE_FORCE_PROXY_LOCKING`: From `sqlite3.c`, 1 means force always
use proxy, 0 means never use proxy, and undefined means use proxy for
non-local files only.
`SQLITE_TMPDIR`: Names the temporary file location for SQLite. When
set, this will be used instead of `TMPDIR`.
`SYSTEMROOT`: (Windows) Used to locate `notepad.exe` as a
fall back comment editor.
`TERM`: If the linenoise library is used (almost certainly not on
Windows), it will check `TERM` to verify that the interactive terminal
is not named on a short list on terminals known to not work with
linenoise. Linenoise is a library that provides command history and
command line editing to interactive programs, and can be used in the
`fossil sqlite3` command.
`TH1_DELETE_INTERP`: Set this variable to ask fossil to explicitly
delete the TH1 interpreter, if it is loaded, then check that it
released all of its allocated memory, when exiting fossil. This is not
strictly necessary, but makes debugging memory leaks easier. See
[main.c near line 386](/artifact/e75796be5338a81c?ln=386,391) for the
code.
`TH1_ENABLE_DOCS`: Override the local or global setting `tcl-docs`
to enable TH1 documents in fossil.
`TH1_ENABLE_HOOKS`: Override the local or global setting `tcl-hooks`
to enable TH1 hooks in fossil.
`TH1_ENABLE_TCL`: Override the local or global setting `tcl` to enable
Tcl in fossil.
`TH1_TEST_ANON_CAPS`: Override the default anonymous permissions used
when processing the `--set-anon-caps` option for the `test-th-eval`,
`test-th-render`, and `test-th-source` test commands.
`TH1_TEST_USER_CAPS`: Override the default user permissions used when
processing the `--set-user-caps` option for the `test-th-eval`,
`test-th-render`, and `test-th-source` test commands.
`TMPDIR`: Names the temporary file location for SQLite.
`USER`: Name of the logged in user on many Unix-like platforms.
Used as the fossil user name if `FOSSIL_USER` is not specified. See
the discussion of Fossil Username below for a lot more detail.
`USERNAME`: Name of the logged in user on Windows platforms.
Used as the fossil user name if `FOSSIL_USER` is not specified. See
the discussion of Fossil Username below for a lot more detail.
`VISUAL`: Name the editor to use for check-in and stash comments.
Overrides the `EDITOR` environment variable. Overridden by the local
or global `editor` setting.
Notes on Related Values
-----------------------
### CGI and JSON Parameters
The JSON API implementation looks up many values in the first of
several places searched. This unifies the parameter handling logic,
allows the caller to choose whether to prefer URL parameters, request
headers, or the POST payload, and allows the `fossil json` command to
share most of the same logic as the `/json` API path. The search order
is a POST payload, GET/COOKIE/non-JSON POST, JSON POST, the system
environment.
See the comment above the implementation of [`json_getenv`][json.c]
for some further discussion.
[json.c]: /artifact/6df1d80dece8968b?ln=277,290
### Comment Editor
The editor used to edit a check-in or stash comment is named by the
local or global setting `editor`. If neither is set, then the environment
variables `VISUAL`, and `EDITOR` are checked in that order.
On Windows, if no editor is named, then Notepad is used. Note that the
operation will be aborted if `notepad.exe` is not found in the Windows
folder.
On Unix-like platforms, if no editor is named, then a message is
displayed on stdout, and stdin is read until a single line containing
only a dot is seen.
### Error logging
If logging errors to a file, fossil will include the values of the
following environment variables in the error log entry if they are
defined: `HTTP_HOST`, `HTTP_USER_AGENT`, `PATH_INFO`, `QUERY_STRING`,
`REMOTE_ADDR`, `REQUEST_METHOD`, `REQUEST_URI`, and `SCRIPT_NAME`.
### Fossil Username
In absence of any explicit setting, fossil will use the same name you
logged in to your platform with, as the user name when interacting
with local and remote repositories. Note that only the name is shared,
fossil makes no attempt to share or leverage any platform's
authentication mechanisms or passwords.
When logging in to a repository, it tries a series of sources for the
user name, and the first non-blank name that succeeds is the logged in
user. The order is:
1. The --user and -U command-line options.
2. If running within an open checkout (the local database is open),
check in its table of values stored per open checkout for the
value stored by `fossil user default USERNAME`.
3. The default user in the repository (setting `default-user`)
4. The `FOSSIL_USER` environment variable.
5. The `USER` environment variable.
6. The `LOGNAME` environment variable.
7. The `USERNAME` environment variable.
8. Check if the user can be extracted from the remote URL, if
there is a remote URL.
Items 2 and 3 are both set by `fossil user default USERNAME`, the
first within an open checkout, the second outside and using the `-R
REPOSITORY` option to identify the repository. Both cases require that
the named user be present in the repository when the default user is
assigned. Although the default user is internally stored as if it were
a setting named `default-user`, it is not accessible through
the `fossil set` command.
Items 5, 6, and 7 cover most of the names of an environment variable
set automatically by the platform with the name of the platform's
logged in user for use by programs. Historically, `USER` comes from
Unix System-V, `LOGNAME` from BSD, and `USERNAME` from Windows, but
many Linux distributions will set both `USER` and `LOGNAME` for broad
compatibility.
When creating a new repository, fossil needs a user name for the admin
user granted the "s" permission. But since fossil generally expects
that `fossil new` or `fossil clone` are used outside of any checkout
(especially when run for the first time without any checkouts at all
or the users's global settings database), it looks in a shorter list
of places for a non-blank name. In the special case of a clone,
`default-user` can be copied from the original, and so it can be set
in the clone even before any users have been created, and in that case
it will be the new admin user. If `default-user` is not set, then the
first found environment variable from the list `FOSSIL_USER`, `USER`,
`LOGNAME`, and `USERNAME`, is the user name. As a final fallback, if
none of those are set, then the default user name is "root".
### Configuration Database Location
Fossil keeps some information pertinent to each user in the user's
[configuration database file][configdb].
The configuration database file includes the global settings
and the list of repositories and checkouts used by `fossil all`.
The location of the configuration database file depends on the
operating system and on the existence of various environment
variables and/or files. In brief, the configuration database is
usually:
* Traditional unix → "`$HOME/.fossil`"
* Windows → "`%LOCALAPPDATA%/_fossil`"
* [XDG-unix][xdg] → "`$HOME/.config/fossil.db`"
[xdg]: https://www.freedesktop.org/wiki/
See the [configuration database location
algorithm][configloc] discussion for full information.
### SQLite VFS to use
See [the SQLite documentation](http://www.sqlite.org/vfs.html) for an
explanation of what a VFS actually is and what it does.
If the default VFS underneath SQLite is not suitable, an alternative
can be selected with either the `--vfs VFSNAME` option or the
`FOSSIL_VFS` environment variable. The `--vfs` option takes
precedence.
### <a id="temp"></a>Temporary File Location
Fossil places some temporary files in the checkout directory. Most notably,
supporting files related to merge conflicts are placed in the same
folder as the merge result.
Other temporary files need a different home. The rules for choosing one are
complicated.
Fossil-specific code uses `FOSSIL_TEMP`, `TEMP`, and `TMP`, in that
order. Fossil’s own test suite prepends `FOSSIL_TEST_TEMP` to that list.
The underlying SQLite code uses several different path sets for its temp
files, depending on the platform type.
On Unix-like platforms, excepting Cygwin, SQLite first checks the
environment variables `SQLITE_TMPDIR` and `TMPDIR`, in that order. If
neither is defined, it falls back to a hard-coded list of paths:
`/var/tmp`, `/usr/tmp`, and `/tmp`. If all of that fails, it uses the
current working directory.
For Cygwin builds, SQLite instead uses the first defined variable in
this list: `SQLITE_TMPDIR`, `TMPDIR`, `TMP`, `TEMP`, and `USERPROFILE`.
For native Windows builds, SQLite simply calls the OS’s [`GetTempPath()`
API][gtp]. See that reference page for details.
[gtp]: https://msdn.microsoft.com/en-us/library/windows/desktop/aa364992%28v=vs.85%29.aspx
That said, it is not unusual for utilities on all platforms to assume
that `TEMP` or `TMP` point somewhere safe for temporary files.
If the identified temporary folder is not writable, then weird things
will happen on all platforms.
### Web browser
Occasionally, fossil wants to launch a web browser for the user, most
obviously as part of the `fossil ui` command. In that specific case,
the browser is launched pointing at the web server started by `fossil
ui` listening on a private TCP port.
On all platforms, if the local or global settings `web-browser` is
set, that is the command used to open a URL.
Otherwise, the specific actions vary by platform.
On Unix-like platforms other than Apple's, it looks for the first
program from the list `xdg-open`, `gnome-open`, `firefox`, and
`google-chrome` that it can find on the `PATH`.
On Apple platforms, it assumes that `open` is the command to open a
URL in the user's configured default browser.
On Windows platforms, it assumes that `start` is the command to open
a URL in the user's configured default browser.

<title>Technical Notes</title>
<h2>What Is A "Technote"?</h2>
In Fossil, a "technical note" or "technote" (formerly called an "event")
is a special kind of [./wikitheory.wiki | wiki page]
that is associated with a point in time rather than having a page name.
Each technote causes a single entry to appear on the
[/timeline?y=e | Timeline Page].
Clicking on the timeline link will display the text of the technote.
The wiki content, the timeline entry text, the
time of the technote, and the timeline background color can all be edited.
As with check-ins, wiki, and tickets, all technotes automatically synchronize
to other repositories. Hence, technotes can be viewed, created, and edited
off-line. And the complete edit history for technotes is maintained
for auditing purposes.
Possible uses for technotes include:
* <b>Milestones</b>. Project milestones, such as releases or beta-test
cycles, can be recorded as technotes. The timeline entry for the technote
can be something simple like "Version 1.2.3" perhaps with a bright
color background to draw attention to the entry and the wiki content
can contain release notes, for example.
* <b>Blog Entries</b>. Blog entries from developers describing the current
state of a project, or rationale for various design decisions, or
roadmaps for future development, can be entered as technotes.
* <b>Process Checkpoints</b>. For projects that have a formal process,
technotes can be used to record the completion or the initiation of
various process steps. For example, a technote can be used to record
the successful completion of a long-running test, perhaps with
performance results and details of where the test was run and who
ran it recorded in the wiki content. The technote can be added
from a script.
* <b>News Articles</b>. Significant occurrences in the life cycle of
a project can be recorded as news articles using technotes. Perhaps the
domain name of the canonical website for a project changes, or new
server hardware is obtained. Such happenings are appropriate for
reporting as news.
* <b>Announcements</b>. Changes to the composition of the development
team or acquisition of new project sponsors can be communicated as
announcements which can be implemented as technotes.
* <b>Signed Checksums</b>. Technotes containing cryptographically signed
checksums can be linked to repository artifacts, thereby creating a
traceable, auditable chain so that users can readily verify the integrity
and authenticity of project deliverables. And the command line interface
to technotes enables embedding such processes in scripts.
No project is required to use technotes. But technotes can help many projects
stay better organized and provide a better historical record of the
development progress.
<h2>Viewing Technotes</h2>
Because technotes are considered a special kind of wiki,
users must have permission to read wiki in order read technotes.
Enable the "j" permission under the /Setup/Users menu in order
to give specific users or user classes the ability to view wiki
and technotes.
Technotes show up on the timeline. Click on the hyperlink beside the
technote title to see the complete text.
<h2>Creating, Editing and Viewing Technotes</h2>
There is a hyperlink under the /wikihelp menu that can be used to create
new technotes. And there is a submenu hyperlink on technote displays for
editing existing technotes.
Technotes can also be created using the <b>wiki create</b> command:
<verbatim>
fossil wiki create TestTechnote -t now --technote-bgcolor lightgreen technote.md
Created new tech note 2021-03-15 13:05:56
</verbatim>
This command inserts a light green technote in the timeline at 2021-03-15 13:05:56, with
the contents of file <b>technote.md</b> and comment "TestTechnote". Specifying a different time using
<b>-t DATETIME</b> will insert the technote at the specified timestamp location in the timeline.
Different technotes can have the same timestamp.
The first argument to create, <b>TECHNOTE-COMMENT</b>, is the title text for the technote
that appears in the timeline.
To view all technotes, use the <b>wiki ls</b> command:
<verbatim>
fossil wiki ls --technote --show-technote-ids
z739263a134bf0da1d28e939f4c4367f51ef4c51 2020-12-19 13:20:19
e15a918a8bed71c2ac091d74dc397b8d3340d5e1 2018-09-22 17:40:10
</verbatim>
A technote ID is the UUID of the technote.
To view an individual technote, use the <b>wiki export</b> command:
<verbatim>
fossil wiki export --technote version-2.16
Release Notes 2021-07-02
This note describes changes in the Fossil snapshot for ...
</verbatim>
The <b>-t|--technote</b> option to the <b>export</b> subcommand takes one of
three identifiers: <b>DATETIME</b>; <b>TECHNOTE-ID</b>; and <b>TAG</b>.
See the [/help?cmd=wiki | wiki help] for specifics.
Users must have check-in privileges (permission "i") in order to
create or edit technotes. In addition, users must have create-wiki
privilege (permission "f") to create new technotes and edit-wiki
privilege (permission "k") in order to edit existing technotes.
Technote content may be formatted as [/wiki_rules | Fossil wiki],
[/md_rules | Markdown], or plain text.

What GUIs are available for fossil?
} {
The fossil executable comes with a [./webui.wiki | web-based GUI] built in.
Just run:
<pre>
<b>fossil [/help/ui|ui]</b> <i>REPOSITORY-FILENAME</i>
</pre>
And your default web browser should pop up and automatically point to
the fossil interface. (Hint: You can omit the <i>REPOSITORY-FILENAME</i>
if you are within an open check-out.)
}
faq {
What is the difference between a "branch" and a "fork"?
} {
This is a big question - too big to answer in a FAQ. Please
read the <a href="branching.wiki">Branching, Forking, Merging,
and Tagging</a> document.
}
faq {
How do I create a new branch?
} {
There are lots of ways:
When you are checking in a new change using the <b>[/help/commit|commit]</b>
command, you can add the option "--branch <i>BRANCH-NAME</i>" to
make the new check-in be the first check-in for a new branch.
If you want to create a new branch whose initial content is the
same as an existing check-in, use this command:
<pre>
<b>fossil [/help/branch|branch] new</b> <i>BRANCH-NAME BASIS</i>
</pre>
The <i>BRANCH-NAME</i> argument is the name of the new branch and the
<i>BASIS</i> argument is the name of the check-in that the branch splits
off from.
If you already have a fork in your check-in tree and you want to convert
that fork to a branch, you can do this from the web interface.
First locate the check-in that you want to be
the initial check-in of your branch on the timeline and click on its
link so that you are on the <b>ci</b> page. Then find the "<b>edit</b>"
link (near the "Commands:" label) and click on that. On the
"Edit Check-in" page, check the box beside "Branching:" and fill in
the name of your new branch to the right and press the "Apply Changes"
button.
}
faq {
How do I tag a check-in?
} {
There are several ways:
When you are checking in a new change using the <b>[/help/commit|commit]</b>
command, you can add a tag to that check-in using the
"--tag <i>TAGNAME</i>" command-line option. You can repeat the --tag
option to give a check-in multiple tags. Tags need not be unique. So,
for example, it is common to give every released version a "release" tag.
If you want to add a tag to an existing check-in, you can use the
<b>[/help/tag|tag]</b> command. For example:
<pre>
<b>fossil [/help/branch|tag] add</b> <i>TAGNAME</i> <i>CHECK-IN</i>
</pre>
The CHECK-IN in the previous line can be any
[./checkin_names.wiki | valid check-in name format].
You can also add (and remove) tags from a check-in using the
[./webui.wiki | web interface]. First locate the check-in that you
want to tag on the timeline, then click on the link to go the detailed
information page for that check-in. Then find the "<b>edit</b>"
link (near the "Commands:" label) and click on that. There are
controls on the edit page that allow new tags to be added and existing
tags to be removed.
}
faq {
How do I create a private branch that won't get pushed back to the
main repository.
} {
Use the <b>--private</b> command-line option on the
<b>commit</b> command. The result will be a check-in which exists in
your local repository only and is never pushed to other repositories.
All descendants of a private check-in are also private.
Unless you specify something different using the <b>--branch</b> and/or
<b>--bgcolor</b> options, the new private check-in will be put on a branch
named "private" with an orange background color.
You can merge from the trunk into your private branch in order to keep
your private branch in sync with the latest changes on the trunk. Once
you have everything in your private branch the way you want it, you can
then merge your private branch back into the trunk and push. Only the
final merge operation will appear in other repositories. It will seem
as if all the changes that occurred on your private branch occurred in
a single check-in.
Of course, you can also keep your branch private forever simply
by not merging the changes in the private branch back into the trunk.

How can I delete inappropriate content from my fossil repository?
} {
See the article on [./shunning.wiki | "shunning"] for details.

faq {
How do I make a clone of the fossil self-hosting repository?
} {
Any of the following commands should work:
<pre>
fossil [/help/clone|clone] https://fossil-scm.org/ fossil.fossil
fossil [/help/clone|clone] https://www2.fossil-scm.org/ fossil.fossil
fossil [/help/clone|clone] https://www3.fossil-scm.org/site.cgi fossil.fossil
</pre>
Once you have the repository cloned, you can open a local check-out
as follows:
<pre>
mkdir src; cd src; fossil [/help/open|open] ../fossil.fossil
</pre>
Thereafter you should be able to keep your local check-out up to date
with the latest code in the public repository by typing:
<pre>
fossil [/help/update|update]

# The fileedit Page
This document describes the limitations of, caveats for, and
disclaimers for the [](/fileedit) page, which provides users with
basic editing features for files via the web interface when they
have [checkin privileges](./caps/index.md).
# Important Caveats and Disclaimers
Predictably, the ability to edit files in a repository from a web
browser halfway around the world comes with several obligatory caveats
and disclaimers...
## <a id="cap"></a> `/fileedit` Does *Nothing* by Default.
In order to "activate" it, a user with [the "setup"
permission](./caps/index.md) must set the
[fileedit-glob](/help?cmd=fileedit-glob) repository setting to a
comma- or newline-delimited list of globs representing a whitelist of
files which may be edited online. Any user with commit access may then
edit files matching one of those globs. Certain pages within the UI
get an "edit" link added to them when the current user's permissions
and the whitelist both permit editing of that file.
## <a id="csrf"></a> CSRF & HTTP Referrer Headers
In order to protect against [Cross-site Request Forgery (CSRF)][csrf]
attacks, Fossil UI features which write to the database require that
the browser send the so-called [HTTP `Referer` header][referer]
(noting that the misspelling of "referrer" is a historical accident
which has long-since been standardized!). Modern browsers, by default,
include such information automatically for *interactive* actions which
lead to a request, e.g. clicking on a link back to the same
server. However, `/fileedit` uses asynchronous ["XHR"][xhr]
connections, which browsers *may* treat differently than strictly
interactive elements.
- **Firefox**: configuration option `network.http.sendRefererHeader`
specifies whether the `Referer` header is sent. It must have a value
of 2 (which is the default) for XHR requests to get the `Referer`
header. Purely interactive Fossil features, in which users directly
activate links or forms, work with a level of 1 or higher.
- **Chrome**: apparently requires an add-on in order to change this
policy, so Chrome without such an add-on will not suppress this
header.
- **Safari**: ???
- **Other browsers**: ???
If `/fileedit` shows an error message saying "CSRF violation," the
problem is that the browser is not sending a `Referer` header to XHR
connections. Fossil does not offer a way to disable its CSRF
protections.

## <a id="commit"></a> `/fileedit` **Works by Creating Commits**
Thus any edits made via that page become a normal part of the
repository.
## <a id="intent"></a> `/fileedit` is *Intended* for use with Embedded Docs
... and similar text files, and is most certainly
**not intended for editing code**.
Editing files with unusual syntax requirements, e.g. hard tabs in
makefiles, may break them. *You Have Been Warned.*
Similarly, though every effort is made to retain the end-of-line
style used by being-edited files, the round-trip through an HTML
textarea element may change the EOLs. The Commit section of the page
offers three different options for how to treat newlines when saving
changes. **Files with mixed EOL styles** *will be normalized to a single
EOL style* when modified using `/fileedit`. When "inheriting" the EOL
style from a previous version which has mixed styles, the first EOL
style detected in the previous version of the file is used.
## <a id="checkout"></a> `/fileedit` **is Not a Replacement for a Checkout**
A full-featured checkout allows far more possibilities than this basic
online editor permits, and the feature scope of `/fileedit` is
intentionally kept small, implementing only the bare necessities
needed for performing basic edits online. It *is not, and will never
be, a replacement for a checkout.*
It is to be expected that users will want to do "more" with this
page, and we generally encourage feature requests, but be aware that
certain types of ostensibly sensible feature requests *will be
rejected* for `/fileedit`. These include, but are not limited to:
- Features which are already provided by other pages, e.g.
the ability to create a new named branch or add tags.
- Features which would require re-implementing significant
capabilities provided only within a checkout (e.g. merging files).
- The ability to edit/manipulate files which are in a local
checkout. (If you have a checkout, use your local editor, not
`/fileedit`.)
- Editing of non-text files, e.g. images. Use a checkout and your
preferred graphics editor.
- Support for syncing/pulling/pushing of a repository before and/or
after edits. Those features cannot be *reliably* provided via a web
interface for several reasons.
Similarly, some *potential* features have significant downsides,
abuses, and/or implementation hurdles which make the decision of
whether or not to implement them subject to notable contributor
debate. e.g. the ability to add new files or remove/rename older
files.
## <a id="storage"></a> `/fileedit` **Stores Only Limited Local Edits While Working**
When changes are made to a given checkin/file combination,
`/fileedit` will, if possible, store them in [`window.localStorage`
or `window.sessionStorage`][html5storage], if available, but...
- Which storage is used is unspecified and may differ across
environments.
- If neither of those is available, the storage is transient and
will not survive a page reload. In this case, the UI issues a clear
warning in the editor tab.
- It stores only the most recent checkin/file combinations which have
been modified (exactly how many may differ - the number will be
noted somewhere in the UI). Note that changing the "executable bit"
is counted as a modification, but the checkin *comment* is *not*
and is reset after a commit.
- If its internal limit on the number of modified files is exceeded,
it silently discards the oldest edits to keep the list at its limit.
Edits are saved whenever the editor component fires its "change"
event, which essentially means as soon as it loses input focus. Thus
to force the browser to save any pending changes, simply click
somwhere on the page outside of the editor.
Exactly how long `localStorage` will survive, and how much it or
`sessionStorage` can hold, is environment-dependent. `sessionStorage`
will survive until the current browser tab is closed, but it survives
across reloads of the same tab.
If `/fileedit` determines that no persistent storage is available a
warning is displayed on the editor page.

# <a id="tips"></a> Tips and Tricks
## <a id="global-js"></a> `fossil` Global-scope JS Object
`/fileedit` is largely implemented in JavaScript, and makes heavy use
of the global-scope `fossil` object, which provides
infrastructure-level features intended for use by Fossil UI pages.
(That said, that infrastructure was introduced with `/fileedit`, and
most pages do not use it.)
The `fossil.page` object represents the UI's current page (on pages
which make use of this API - most do not). That object supports
listening to page-specific events so that JS code installed via
[client-side edits to the site skin's footer](customskin.md) may react
to those changes somehow. The next section describes one such use for
such events...
## <a id="syn-hl"></a> Integrating Syntax Highlighting
Assuming a repository has integrated a 3rd-party syntax highlighting
solution, it can probably (depending on its API) be told how to
highlight `/fileedit`'s wiki/markdown-format previews. Here are
instructions for doing so with [highlightjs](https://highlightjs.org/):
At the very bottom of the [site skin's footer](customskin.md), add a
script tag similar to the following:
```javascript
<script nonce="$<nonce>">
if(window.fossil && fossil.page && fossil.page.name==='fileedit'){
fossil.page.addEventListener(
'fileedit-preview-updated',
(ev)=>{
if(ev.detail.previewMode==='wiki'){
ev.detail.element.querySelectorAll(
'code[class^=language-]'
).forEach((e)=>hljs.highlightBlock(e));
}
}
);
}
</script>
```
Note that the `nonce="$<nonce>"` part is intended to be entered
literally as shown above. It will be expanded to contain the current
request's nonce value when the page is rendered.
The first line of the script just ensures that the expected JS-level
infrastructure is loaded. It's only loaded in the `/fileedit` page and
possibly pages added or "upgraded" since `/fileedit`'s introduction.
The part in the `if` block adds an event listener to the `/fileedit`
app which gets called when the preview is refreshed. That event
contains 3 properties:
- `previewMode`: a string describing the current preview mode: `wiki`
(which includes Fossil-native wiki and markdown), `text`,
`htmlInline`, `htmlIframe`. We should "probably" only highlight wiki
text, and thus the example above limits its work to that type of
preview. It won't work with `htmlIframe`, as that represents an
iframe element which contains a complete HTML document.
- `element`: the DOM element in which the preview is rendered.
- `mimetype`: the mimetype of the being-previewed content, as determined
by Fossil (by its file extension).
The event listener callback shown above doesn't use the `mimetype`,
but makes use of the other two. It fishes all `code` blocks out of
the preview which explicitly have a CSS class named
`language-`something, and then asks highlightjs to highlight them.
## <a id="editor"></a> Integrating a Custom Editor Widget
(These instructions also work for the `/wikiedit` page by replacing
"fileedit" with "wikiedit" in any strings or symbol names!)
It is possible to replace `/fileedit`'s basic text-editing widget (a
`textarea` element) with a fancy 3rd-party editor widget by following
these instructions...
All JavaScript code which follows is assumed to be in a script tag
similar to the one shown in the previous section:
```javascript
<script nonce="$<nonce>">
if(window.fossil && fossil.page && fossil.page.name==='fileedit'){
// code specific to the fileedit page goes here
}
</script>
```
First, install proxy functions so that `fossil.page.fileContent()`
can get and set your content:
```
fossil.page.setContentMethods(
function(){ return text-form content of your widget },
function(content){ set text-form content of your widget }
};
```
Secondly, we need to alert the editor app when there are changes so
that it can do things like store edits locally so that they are not
lost on a page reload. How that is done is completely dependent on the
3rd-party editor widget, but it generically looks something like:
```
myCustomWidget.on('eventName', ()=>fossil.page.notifyOfChange());
```
Lastly, if the 3rd-party editor does *not* hide or remove the native
editor widget, and does not inject itself into the DOM on the caller's
behalf, we can replace the native widget with the 3rd-party one with:
```javascript
fossil.page.replaceEditorWidget(yourNewWidgetElement);
```
That method must be passed a DOM element and may only be called once:
it *removes itself* the first time it is called.
That should be all there is to it. When `fossil.page` needs to get the
being-edited content, it will call the installed content-getter
function with no arguments, and when it sets the content (immediately
after (re)loading a file or grabbing local edits), it will pass that
content to the installed content-setter method. Those, in turn will
trigger the installed proxies and fire any relevant events.
Below is an example of Fossil skin footer content which plugs in the
TinyMCE HTML editor into the `/wikiedit` page, but the process is
identical for `/fileedit` (noting that `/fileedit` may need to be able
to edit multiple types of files for which a special-purpose editor
like TinyMCE may not be suitable). Note that any paths to CSS and JS
resources of course need to be modified to suit one's own
installation.
```

tinymce.init({selector: 'textarea#'+elemId});
const widget = tinymce.get(elemId);
fossil.page.setContentMethods(
function(){return widget.getContent()},
function(content){widget.setContent(content)}
);
widget.on('change', function(){
if(widget.isDirty()) fossil.page.notifyOfChange();
});
});
}
</script>
```

<title>Fossil File Formats</title>
The global state of a fossil repository is kept simple so that it can
endure in useful form for decades or centuries.
A fossil repository is intended to be readable,
searchable, and extensible by people not yet born.
The global state of a fossil repository is an unordered
set of <i>artifacts</i>.
An artifact might be a source code file, the text of a wiki page,
part of a trouble ticket, a description of a check-in including all
the files in that check-in with the check-in comment and so forth.
Artifacts are broadly grouped into two types: content artifacts and
structural artifacts. Content artifacts are the raw project source-code
files that are checked into the repository. Structural artifacts have
special formatting rules and are used to show the relationships between
other artifacts in the repository. It is possible for an artifact to
be both a structure artifact and a content artifact, though this is
rare. Artifacts can be text or binary.
In addition to the global state,
each fossil repository also contains local state.
The local state consists of web-page formatting
preferences, authorized users, ticket display and reporting formats,
and so forth. The global state is shared in common among all
repositories for the same project, whereas the local state is often
different in separate repositories.
The local state is not versioned and is not synchronized
with the global state.
The local state is not composed of artifacts and is not intended to be enduring.
This document is concerned with global state only. Local state is only
mentioned here in order to distinguish it from global state.
<h2 id="names">1.0 Artifact Names</h2>
Each artifact in the repository is named by a hash of its content.
No prefixes, suffixes, or other information is added to an artifact before
the hash is computed. The artifact name is just the (lower-case
hexadecimal) hash of the raw artifact.
Fossil currently computes artifact names using either SHA1 or SHA3-256. It
is relatively easy to add new algorithms in the future, but there are no
plans to do so at this time.
When referring to artifacts in using tty commands or webpage URLs, it is
sufficient to specify a unique prefix for the artifact name. If the input
prefix is not unique, Fossil will show an error. Within a structural
artifact, however, all references to other artifacts must be the complete
hash.
Prior to Fossil version 2.0, all names were formed from the SHA1 hash of
the artifact. The key innovation in Fossil 2.0 was adding support for
alternative hash algorithms.
<h2 id="structural">2.0 Structural Artifacts</h2>
A structural artifact is an artifact with a particular format
that is used to define the relationships between other artifacts in the
repository.
Fossil recognizes the following kinds of structural
artifacts:
<ul>
<li> [#manifest | Manifests] </li>
<li> [#cluster | Clusters] </li>
<li> [#ctrl | Control Artifacts] </li>
<li> [#wikichng | Wiki Pages] </li>
<li> [#tktchng | Ticket Changes] </li>
<li> [#attachment | Attachments] </li>
<li> [#event | TechNotes] </li>
<li> [#forum | Forum Posts] </li>
</ul>
These eight structural artifact types are described in subsections below.
Structural artifacts are UTF-8 text. The artifact may be PGP clearsigned.
After removal of the PGP clearsign header and suffix (if any) a structural
artifact consists of one or more "cards" separated by a single newline
(ASCII: 0x0a) character. Each card begins with a single
character "card type". Zero or more arguments may follow
the card type. All arguments are separated from each other
and from the card-type character by a single space
character. There is no surplus white space between arguments
and no leading or trailing whitespace except for the newline
character that acts as the card separator. All cards must be in strict
lexicographical order (except for an
[./fileformat.wiki#outofordercards|historical bug compatibility]).
There may not be any duplicate cards.
In the current implementation (as of 2017-02-27) the artifacts that
make up a fossil repository are stored as delta- and zlib-compressed
blobs in an <a href="http://www.sqlite.org/">SQLite</a> database. This
is an implementation detail and might change in a future release. For
the purpose of this article "file format" means the format of the artifacts,
not how the artifacts are stored on disk. It is the artifact format that
is intended to be enduring. The specifics of how artifacts are stored on
disk, though stable, is not intended to live as long as the
artifact format.
<h3 id="manifest">2.1 The Manifest</h3>
A manifest defines a check-in.
A manifest contains a list of artifacts for
each file in the project and the corresponding filenames, as
well as information such as parent check-ins, the username of the
programmer who created the check-in, the date and time when
the check-in was created, and any check-in comments associated
with the check-in.
Allowed cards in the manifest are as follows:
<div class="indent">
<b>B</b> <i>baseline-manifest</i><br>
<b>C</b> <i>checkin-comment</i><br>
<b>D</b> <i>time-and-date-stamp</i><br>
<b>F</b> <i>filename</i> ?<i>hash</i>? ?<i>permissions</i>? ?<i>old-name</i>?<br>
<b>N</b> <i>mimetype</i><br>
<b>P</b> <i>artifact-hash</i>+<br>
<b>Q</b> (<b>+</b>|<b>-</b>)<i>artifact-hash</i> ?<i>artifact-hash</i>?<br>
<b>R</b> <i>repository-checksum</i><br>
<b>T</b> (<b>+</b>|<b>-</b>|<b>*</b>)<i>tag-name</i> <b>*</b> ?<i>value</i>?<br>
<b>U</b> <i>user-login</i><br>
<b>Z</b> <i>manifest-checksum</i>
</div>
A manifest may optionally have a single <b>B</b> card. The <b>B</b> card specifies
another manifest that serves as the "baseline" for this manifest. A
manifest that has a <b>B</b> card is called a delta-manifest and a manifest
that omits the <b>B</b> card is a baseline-manifest. The other manifest
identified by the argument of the <b>B</b> card must be a baseline-manifest.
A baseline-manifest records the complete contents of a check-in.
A delta-manifest records only changes from its baseline.
A manifest must have exactly one <b>C</b> card. The sole argument to
the <b>C</b> card is a check-in comment that describes the check-in that
the manifest defines. The check-in comment is text. The following
escape sequences are applied to the text:
A space (ASCII 0x20) is represented as "\s" (ASCII 0x5C, 0x73). A
newline (ASCII 0x0a) is "\n" (ASCII 0x5C, x6E). A backslash
(ASCII 0x5C) is represented as two backslashes "\\". Apart from
space and newline, no other whitespace characters are allowed in
the check-in comment. Nor are any unprintable characters allowed
in the comment.
A manifest must have exactly one <b>D</b> card. The sole argument to
the <b>D</b> card is a date-time stamp in the ISO8601 format. The
date and time should be in coordinated universal time (UTC).
The format one of:
<pre class="indent"><i>YYYY-MM-DD<b>T</b>HH:MM:SS
YYYY-MM-DD<b>T</b>HH:MM:SS.SSS</i></pre>
A manifest has zero or more <b>F</b> cards. Each <b>F</b> card identifies a file
that is part of the check-in. There are one, two, three, or four
arguments. The first argument is the pathname of the file in the
check-in relative to the root of the project file hierarchy. No ".."
or "." directories are allowed within the filename. Space characters
are escaped as in <b>C</b> card comment text. Backslash characters and
newlines are not allowed within filenames. The directory separator
character is a forward slash (ASCII 0x2F). The second argument to the
<b>F</b> card is the lower-case hexadecimal artifact hash of
the content artifact. The second argument is required for baseline
manifests but is optional for delta manifests. When the second
argument to the <b>F</b> card is omitted, it means that the file has been
deleted relative to the baseline (files removed in baseline manifests
versions are <em>not</em> added as <b>F</b> cards). The optional 3rd argument
defines any special access permissions associated with the file. This
can be defined as "x" to mean that the file is executable or "l"
(small letter ell) to mean a symlink. All files are always readable
and writable. This can be expressed by "w" permission if desired but
is optional. The file format might be extended with new permission
letters in the future. The optional 4th argument is the name of the
same file as it existed in the parent check-in. If the name of the
file is unchanged from its parent, then the 4th argument is omitted.
A manifest has zero or one <b>N</b> cards. The <b>N</b> card specifies the mimetype for the
text in the comment of the <b>C</b> card. If the <b>N</b> card is omitted, a default mimetype
is used.
A manifest has zero or one <b>P</b> cards. Most manifests have one <b>P</b> card.
The <b>P</b> card has a varying number of arguments that
define other manifests from which the current manifest
is derived. Each argument is a lowercase
hexadecimal artifact hash of a predecessor manifest. All arguments
to the <b>P</b> card must be unique within that card.
The first argument is the artifact hash of the direct ancestor of the manifest.
Other arguments define manifests with which the first was
merged to yield the current manifest. Most manifests have
a <b>P</b> card with a single argument. The first manifest in the
project has no ancestors and thus has no <b>P</b> card or (depending
on the Fossil version) an empty <b>P</b> card (no arguments).
A manifest has zero or more <b>Q</b> cards. A <b>Q</b> card is similar to a <b>P</b> card
in that it defines a predecessor to the current check-in. But
whereas a <b>P</b> card defines the immediate ancestor or a merge
ancestor, the <b>Q</b> card is used to identify a single check-in or a small
range of check-ins which were cherry-picked for inclusion in or
exclusion from the current manifest. The first argument of
the <b>Q</b> card is the artifact ID of another manifest (the "target")
which has had its changes included or excluded in the current manifest.
The target is preceded by "+" or "-" to show inclusion or
exclusion, respectively. The optional second argument to the
<b>Q</b> card is another manifest artifact ID which is the "baseline"
for the cherry-pick. If omitted, the baseline is the primary
parent of the target. The
changes included or excluded consist of all changes moving from
the baseline to the target.
The <b>Q</b> card was added to the interface specification on 2011-02-26.
Older versions of Fossil will reject manifests that contain <b>Q</b> cards.
A manifest may optionally have a single <b>R</b> card. The <b>R</b> card has
a single argument which is the MD5 checksum of all files in
the check-in except the manifest itself. The checksum is expressed
as 32 characters of lowercase hexadecimal. The checksum is
computed as follows: For each file in the check-in (except for
the manifest itself) in strict sorted lexicographical order,
take the pathname of the file relative to the root of the
repository, append a single space (ASCII 0x20), the
size of the file in ASCII decimal, a single newline
character (ASCII 0x0A), and the complete text of the file.
Compute the MD5 checksum of the result.
A manifest might contain one or more <b>T</b> cards used to set
[./branching.wiki#tags | tags or properties]
on the check-in. The format of the <b>T</b> card is the same as
described in <i>Control Artifacts</i> section below, except that the
second argument is the single character "<b>*</b>" instead of an
artifact ID. The <b>*</b> in place of the artifact ID indicates that
the tag or property applies to the current artifact. It is not
possible to encode the current artifact ID as part of an artifact,
since the act of inserting the artifact ID would change the artifact ID,
hence a <b>*</b> is used to represent "self". <b>T</b> cards are typically
added to manifests in order to set the <b>branch</b> property and a
symbolic name when the check-in is intended to start a new branch.
Each manifest has a single <b>U</b> card. The argument to the <b>U</b> card is
the login of the user who created the manifest. The login name
is encoded using the same character escapes as is used for the
check-in comment argument to the <b>C</b> card.
A manifest must have a single <b>Z</b> card as its last line. The argument
to the <b>Z</b> card is a 32-character lowercase hexadecimal MD5 hash
of all prior lines of the manifest up to and including the newline
character that immediately precedes the "Z", excluding any PGP
clear-signing prefix. The <b>Z</b> card is
a sanity check to prove that the manifest is well-formed and
consistent.
A sample manifest from Fossil itself can be seen
[/artifact/28987096ac | here].
<h3 id="cluster">2.2 Clusters</h3>
A cluster is an artifact that declares the existence of other artifacts.
Clusters are used during repository synchronization to help
reduce network traffic. As such, clusters are an optimization and
may be removed from a repository without loss or damage to the
underlying project code.
Allowed cards in the cluster are as follows:
<div class="indent">
<b>M</b> <i>artifact-id</i><br />
<b>Z</b> <i>checksum</i>
</div>
A cluster contains one or more <b>M</b> cards followed by a single <b>Z</b> card.
Each <b>M</b> card has a single argument which is the artifact ID of
another artifact in the repository. The <b>Z</b> card works exactly like
the <b>Z</b> card of a manifest. The argument to the <b>Z</b> card is the
lower-case hexadecimal representation of the MD5 checksum of all
prior cards in the cluster. The <b>Z</b> card is required.
An example cluster from Fossil can be seen
[/artifact/d03dbdd73a2a8 | here].
<h3 id="ctrl">2.3 Control Artifacts</h3>
Control artifacts are used to assign properties to other artifacts
within the repository.
Allowed cards in a control artifact are as follows:
<div class="indent">
<b>D</b> <i>time-and-date-stamp</i><br />
<b>T</b> (<b>+</b>|<b>-</b>|<b>*</b>)<i>tag-name</i> <i>artifact-id</i> ?<i>value</i>?<br />
<b>U</b> <i>user-name</i><br />
<b>Z</b> <i>checksum</i><br />
</div>
A control artifact must have one <b>D</b> card, one <b>U</b> card, one <b>Z</b> card and
one or more <b>T</b> cards. No other cards or other text is
allowed in a control artifact. Control artifacts might be PGP
clearsigned.
The <b>D</b> card and the <b>Z</b> card of a control artifact are the same
as in a manifest.
The <b>T</b> card represents a [./branching.wiki#tags | tag or property]
that is applied to
some other artifact. The <b>T</b> card has two or three values. The
second argument is the lowercase artifact ID of the artifact
to which the tag is to be applied. The
first value is the tag name. The first character of the tag
is either "+", "-", or "*". The "+" means the tag should be added
to the artifact. The "-" means the tag should be removed.
The "*" character means the tag should be added to the artifact
and all direct descendants (but not descendants through a merge) down
to but not including the first descendant that contains a
more recent "-", "*", or "+" tag with the same name.
The optional third argument is the value of the tag. A tag
without a value is a Boolean.
When two or more tags with the same name are applied to the
same artifact, the tag with the latest (most recent) date is
used.
Some tags have special meaning. The "comment" tag when applied
to a check-in will override the check-in comment of that check-in
for display purposes. The "user" tag overrides the name of the
check-in user. The "date" tag overrides the check-in date.
The "branch" tag sets the name of the branch that at check-in
belongs to. Symbolic tags begin with the "sym-" prefix.
The <b>U</b> card is the name of the user that created the control
artifact. The <b>Z</b> card is the usual required artifact checksum.
An example control artifact can be seen [/info/9d302ccda8 | here].
<h3 id="wikichng">2.4 Wiki Pages</h3>
A wiki artifact defines a single version of a
single wiki page.
Wiki artifacts accept
the following card types:
<div class="indent">
<b>C</b> <i>change-comment</i><br>
<b>D</b> <i>time-and-date-stamp</i><br />
<b>L</b> <i>wiki-title</i><br />
<b>N</b> <i>mimetype</i><br />
<b>P</b> <i>parent-artifact-id</i>+<br />
<b>U</b> <i>user-name</i><br />
<b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br />
<b>Z</b> <i>checksum</i>
</div>
The <b>D</b> card is the date and time when the wiki page was edited.
The <b>P</b> card specifies the parent wiki pages, if any. The <b>L</b> card
gives the name of the wiki page. The optional <b>N</b> card specifies
the mimetype of the wiki text. If the <b>N</b> card is omitted, the
mimetype is assumed to be text/x-fossil-wiki.
The <b>U</b> card specifies the login
of the user who made this edit to the wiki page. The <b>Z</b> card is
the usual checksum over the entire artifact and is required.
The <b>W</b> card is used to specify the text of the wiki page. The
argument to the <b>W</b> card is an integer which is the number of bytes
of text in the wiki page. That text follows the newline character
that terminates the <b>W</b> card. The wiki text is always followed by one
extra newline.
The <b>C</b> card on a wiki page is optional. The argument is a comment
that explains why the changes were made. The ability to have a <b>C</b>
card on a wiki page artifact was added on 2019-12-02 at the suggestion
of user George Krivov and is not currently used or generated by the
implementation. Older versions of Fossil will reject a wiki-page
artifact that includes a <b>C</b> card.
An example wiki artifact can be seen
[/artifact?name=7b2f5fd0e0&txt=1 | here].
<h3 id="tktchng">2.5 Ticket Changes</h3>
A ticket-change artifact represents a change to a trouble ticket.
The following cards are allowed on a ticket change artifact:
<div class="indent">
<b>D</b> <i>time-and-date-stamp</i><br />
<b>J</b> ?<b>+</b>?<i>name</i> ?<i>value</i>?<br />
<b>K</b> <i>ticket-id</i><br />
<b>U</b> <i>user-name</i><br />
<b>Z</b> <i>checksum</i>
</div>
The <b>D</b> card is the usual date and time stamp and represents the point
in time when the change was entered. The <b>U</b> card is the login of the
programmer who entered this change. The <b>Z</b> card is the required checksum over
the entire artifact.
Every ticket has a distinct ticket-id:
40-character lower-case hexadecimal number.
The ticket-id is given in the <b>K</b> card. A ticket exists if it contains one or
more changes. The first "change" to a ticket is what brings the
ticket into existence.
<b>J</b> cards specify changes to the "value" of "fields" in the ticket.
If the <i>value</i> parameter of the <b>J</b> card is omitted, then the
field is set to an empty string.
Each fossil server has a ticket configuration which specifies the fields it
understands. The ticket configuration is part of the local state for
the repository and thus can vary from one repository to another.
Hence a <b>J</b> card might specify a <i>field</i> that does not exist in the
local ticket configuration. If a <b>J</b> card specifies a <i>field</i> that
is not in the local configuration, then that <b>J</b> card
is simply ignored.
The first argument of the <b>J</b> card is the field name. The second
value is the field value. If the field name begins with "+" then
the value is appended to the prior value. Otherwise, the value
on the <b>J</b> card replaces any previous value of the field.
The field name and value are both encoded using the character
escapes defined for the <b>C</b> card of a manifest.
An example ticket-change artifact can be seen
[/artifact/91f1ec6af053 | here].
<h3 id="attachment">2.6 Attachments</h3>
An attachment artifact associates some other artifact that is the
attachment (the source artifact) with a ticket or wiki page or
technical note to which
the attachment is connected (the target artifact).
The following cards are allowed on an attachment artifact:
<div class="indent">
<b>A</b> <i>filename target</i> ?<i>source</i>?<br />
<b>C</b> <i>comment</i><br />
<b>D</b> <i>time-and-date-stamp</i><br />
<b>N</b> <i>mimetype</i><br />
<b>U</b> <i>user-name</i><br />
<b>Z</b> <i>checksum</i>
</div>
The <b>A</b> card specifies a filename for the attachment in its first argument.
The second argument to the <b>A</b> card is the name of the wiki page or
ticket or technical note to which the attachment is connected. The
third argument is either missing or else it is the lower-case artifact
ID of the attachment itself. A missing third argument means that the
attachment should be deleted.
The <b>C</b> card is an optional comment describing what the attachment is about.
The <b>C</b> card is optional, but there can only be one.
A single <b>D</b> card is required to give the date and time when the attachment
was applied.
There may be zero or one <b>N</b> cards. The <b>N</b> card specifies the mimetype of the
comment text provided in the <b>C</b> card. If the <b>N</b> card is omitted, the <b>C</b> card
mimetype is taken to be text/plain.
A single <b>U</b> card gives the name of the user who added the attachment.
If an attachment is added anonymously, then the <b>U</b> card may be omitted.
The <b>Z</b> card is the usual checksum over the rest of the attachment artifact.
The <b>Z</b> card is required.
<h3 id="event">2.7 Technical Notes</h3>
A technical note or "technote" artifact (formerly known as an "event" artifact)
associates a timeline comment and a page of text
(similar to a wiki page) with a point in time. Technotes can be used
to record project milestones, release notes, blog entries, process
checkpoints, or news articles.
The following cards are allowed on a technote artifact:
<div class="indent">
<b>C</b> <i>comment</i><br>
<b>D</b> <i>time-and-date-stamp</i><br />
<b>E</b> <i>technote-time</i> <i>technote-id</i><br />
<b>N</b> <i>mimetype</i><br />
<b>P</b> <i>parent-artifact-id</i>+<br />
<b>T</b> <b>+</b><i>tag-name</i> <b>*</b> ?<i>value</i>?<br />
<b>U</b> <i>user-name</i><br />
<b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br />
<b>Z</b> <i>checksum</i>
</div>
The <b>C</b> card contains text that is displayed on the timeline for the
technote. The <b>C</b> card is optional, but there can only be one.
A single <b>D</b> card is required to give the date and time when the
technote artifact was created. This is different from the time at which
the technote appears on the timeline.
A single <b>E</b> card gives the time of the technote (the point on the timeline
where the technote is displayed) and a unique identifier for the technote.
When there are multiple artifacts with the same technote-id, the one with
the most recent <b>D</b> card is the only one used. The technote-id must be a
40-character lower-case hexadecimal string.
The optional <b>N</b> card specifies the mimetype of the text of the technote
that is contained in the <b>W</b> card. If the <b>N</b> card is omitted, then the
<b>W</b> card text mimetype is assumed to be text/x-fossil-wiki, which is the
Fossil wiki format.
The optional <b>P</b> card specifies a prior technote with the same technote-id
from which the current technote is an edit. The <b>P</b> card is a hint to the
system that it might be space efficient to store one technote as a delta of
the other.
A technote might contain one or more <b>T</b> cards used to set
[./branching.wiki#tags | tags or properties]
on the technote. The format of the <b>T</b> card is the same as
described in [#ctrl | Control Artifacts] section above, except that the
second argument is the single character "<b>*</b>" instead of an
artifact ID and the name is always prefaced by "<b>+</b>".
The <b>*</b> in place of the artifact ID indicates that
the tag or property applies to the current artifact. It is not
possible to encode the current artifact ID as part of an artifact,
since the act of inserting the artifact ID would change the artifact ID,
hence a <b>*</b> is used to represent "self". The "<b>+</b>" on the
name means that tags can only be "add" and they can only be non-propagating
tags. In a technote, <b>T</b> cards are normally used to set the background
display color for timelines.
The optional <b>U</b> card gives the name of the user who entered the technote.
A single <b>W</b> card provides wiki text for the document associated with the
technote. The format of the <b>W</b> card is exactly the same as for a
[#wikichng | wiki artifact].
The <b>Z</b> card is the required checksum over the rest of the artifact.
<h3 id="forum">2.8 Forum Posts</h3>
Forum posts are intended as a mechanism for users and developers to
discuss a project. Forum posts are like messages on a mailing list.
The following cards are allowed on an forum post artifact:
<div class="indent">
<b>D</b> <i>time-and-date-stamp</i><br />
<b>G</b> <i>thread-root</i><br />
<b>H</b> <i>thread-title</i><br />
<b>I</b> <i>in-reply-to</i><br />
<b>N</b> <i>mimetype</i><br />
<b>P</b> <i>parent-artifact-id</i><br />
<b>U</b> <i>user-name</i><br />
<b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br />
<b>Z</b> <i>checksum</i>
</div>
Every forum post must have either one <b>I</b> card and one <b>G</b> card
or one <b>H</b> card.
Forum posts are organized into topic threads. The initial
post for a thread (the root post) has an <b>H</b> card giving the title or
subject for that thread. The argument to the <b>H</b> card is a string
in the same format as a comment string in a <b>C</b> card.
All follow-up posts have an <b>I</b> card that
indicates which prior post in the same thread the current forum
post is replying to, and a <b>G</b> card specifying the root post for
the entire thread. The argument to <b>G</b> and <b>I</b> cards is the
artifact hash for the prior forum post to which the card refers.
In theory, it is sufficient for follow-up posts to have only an
<b>I</b> card, since the <b>G</b> card value could be computed by following a
chain of <b>I</b> cards. However, the <b>G</b> card is required in order to
associate the artifact with a forum thread in the case where an
intermediate artifact in the <b>I</b> card chain is shunned or otherwise
becomes unreadable.
A single <b>D</b> card is required to give the date and time when the
forum post was created.
The optional <b>N</b> card specifies the mimetype of the text of the technote
that is contained in the <b>W</b> card. If the <b>N</b> card is omitted, then the
<b>W</b> card text mimetype is assumed to be text/x-fossil-wiki, which is the
Fossil wiki format.
The optional <b>P</b> card specifies a prior forum post for which this
forum post is an edit. For display purposes, only the child post
is shown, though the historical post is retained as a record.
If <b>P</b> cards are used and there exist multiple versions of the same
forum post, then <b>I</b> cards for other artifacts refer to whichever
version of the post was current at the time the reply was made,
but <b>G</b> cards refer to the initial, unedited root post for the thread.
Thus, following the chain of <b>I</b> cards back to the root of the thread
may land on a different post than the one given in the <b>G</b> card.
However, following the chain of <b>I</b> cards back to the thread root,
then following <b>P</b> cards back to the initial version of the thread
root must give the same artifact as is provided by the <b>G</b> card,
otherwise the artifact containing the <b>G</b> card is considered invalid
and should be ignored.
In general, <b>P</b> cards may contain multiple arguments, indicating a
merge. But since forum posts cannot be merged, the
<b>P</b> card of a forum post may only contain a single argument.
The <b>U</b> card gives name of the user who entered the forum post.
A single <b>W</b> card provides wiki text for the forum post.
The format of the <b>W</b> card is exactly the same as for a
[#wikichng | wiki artifact].
The <b>Z</b> card is the required checksum over the rest of the artifact.
<h2 id="summary">3.0 Card Summary</h2>
The following table summarizes the various kinds of cards that appear
on Fossil artifacts. A blank entry means that combination of card and
artifact is not legal. A number or range of numbers indicates the number
of times a card may (or must) appear in the corresponding artifact type.
e.g. a value of 1 indicates a required unique card and 1+ indicates that one
or more such cards are required.

Footnotes:
1) T-card names may not be made up of only hexadecimal characters, as
they would be indistinguishable from a hash prefix.
2) Tags in [#ctrl | Control Artifacts] may not be
self-referential. i.e. their target hash may not be <tt>*</tt>.
3) Tags in [#event | Technotes] must be self-referential. i.e. their
target hash must be <tt>*</tt>. Similarly, technote tags may only
be non-propagating "add" tags. i.e. their name prefix must be
<tt>+</tt>.
4) [#forum | Forum Posts] must have either one H-card or one
I-card, not both.
5) [#forum | Forum Post] P-cards may have only a single parent
hash. i.e. they may not have merge parents.

This section contains additional information which may be useful when
implementing algorithms described above.
<h3 id="outofordercards">4.1 Relaxed Card Ordering Due To An Historical Bug</h3>
All cards of a structural artifact should be in lexicographical order.
The Fossil implementation verifies this and rejects any structural
artifact which has out-of-order cards. Futhermore, when Fossil is
generating new structural artifacts, it runs the generated artifact
through the parser to confirm that all cards really are in the correct
order before committing the transaction. In this way, Fossil prevents
bugs in the code from accidentally inserting misformatted artifacts.
The test parse of newly created artifacts is part of the
[./selfcheck.wiki|self-check strategy] of Fossil. It takes a
few more CPU cycles to double check each artifact before inserting it.
The developers consider those CPU cycles well-spent.
However, the card-order safety check was accidentally disabled due to
[15d04de574383d61|a bug].
And while that bug was lurking undetected in the code,
[5e67a7f4041a36ad|another bug] caused the N cards of Technical Notes
to occur after the P card rather than before.
Thus for a span of several years, Technical Note artifacts were being
inserted into Fossil repositories that had their N and P cards in the
wrong order.
Both bugs have now been fixed. However, to prevent historical
Technical Note artifacts that were inserted by users in good faith
from being rejected by newer Fossil builds, the card ordering
requirement is relaxed slightly. The actual implementation is this:
<p class=blockquote>
"All cards must be in strict lexicographic order, except that the
N and P cards of a Technical Note artifact are allowed to be
interchanged."
</p>
Future versions of Fossil might strengthen this slightly to only allow
the out of order N and P cards for Technical Notes entered before
a certain date.
<h3>4.2 R-Card Hash Calculation</h3>
Given a manifest file named <tt>MF</tt>, the following Bash shell code
demonstrates how to compute the value of the <b>R</b> card in that manifest.
This example uses manifest [28987096ac]. Lines starting with <tt>#</tt> are
shell input and other lines are output. This demonstration assumes that the
file versions represented by the input manifest are checked out
under the current directory.
<nowiki><pre>
# head MF
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
C Make\sthe\s"clearsign"\sPGP\ssigning\sdefault\sto\soff.

cat $i; \

Minor caveats: the above demonstration will work only when none of the
filenames in the manifest are "fossilized" (encoded) because they contain
spaces. In that case the shell-generated hash would differ because the
<tt>stat</tt> calls will fail to find such files (which are output in encoded
form here). That approach also won't work for delta manifests. Calculating
the <b>R</b> card for delta manifests requires traversing both the delta and its baseline in
lexical order of the files, preferring the delta's copy if both contain
a given file.

In addition, it will create a binary file _FOSSIL_ to keep track of changes (on non-Windows systems it is called <tt>.fslckout</tt>). <h2>Add new files</h2> <tt>fossil add .</tt> To tell Fossil to add new files to the repository. The files aren't actually added until you run "<tt>fossil commit</tt>. When using ".", it tells Fossil to add all the files in the current directory recursively, i.e. including all the files in all the subdirectories. Note: To tell Fossil to ignore some extensions: <tt>fossil settings ignore-glob "*.o,*.obj,*.exe" --global</tt> <h2>Remove files that haven't been committed yet</h2> <tt>fossil delete myfile.c</tt> This will simply remove the item from the list of files that were previously added through "<tt>fossil add</tt>". <h2>Check current status</h2> <tt>fossil changes</tt> This shows the list of changes that have been done and will be committed the next time you run "<tt>fossil commit</tt>". It's a useful command to run before running "<tt>fossil commit</tt>" just to check that things are OK before proceeding. <h2>Commit changes</h2> To actually apply the pending changes to the repository, e.g. new files marked for addition, checked-out files that have been edited and must be checked-in, etc. <tt>fossil commit -m "Added stuff"</tt> If no file names are provided on the command-line then all changes will be checked in, otherwise just the listed file(s) will be checked in. <h2>Compare two revisions of a file</h2> If you wish to compare the last revision of a file and its checked out version in your work directory: <tt>fossil gdiff myfile.c</tt> If you wish to compare two different revisions of a file in the repository: <tt>fossil finfo myfile</tt> Note the first hash, which is the hash of the commit when the file was committed. <tt>fossil gdiff --from HASH#1 --to HASH#2 myfile.c</tt> <h2>Cancel changes and go back to previous revision</h2> <tt>fossil revert myfile.c</tt> Fossil does not prompt when reverting a file. It simply reminds the user about the "undo" command, just in case the revert was a mistake. |

<title>Fossil Forums</title>
<h2>Introduction</h2>
Fossil includes a built-in discussion forum, designed to substitute
for a mailing list. Email notification is available to receive posts,
but the web-based UI must be used to enter new posts. Advantages of
the forum include:
* <b>Easy to Administer:</b> If you have already set up a
[./server/|Fossil server] with [./alerts.md|email alerts]
then turning on the forum feature
is just a matter of flipping some permission bits. There is
no new software to install and configure, and the same logins
and passwords work.
* <b>Consistent Display:</b> Forum posts can be in [/md_rules|Markdown],
[/wiki_rules|Fossil Wiki], or plain text. Whichever format is used, the result is
displayed consistently across all platforms and operating systems and
between mobile devices and desktops.
* <b>Editable:</b> Forum posts can be amended after they are sent,
to fix typos or provide updates. The original posts are preserved
as part of the historical record, but only the amended posts are
displayed by default.
* <b>Built-in Full-Text Search:</b> Forum posts can be included in
the index used by the built-in Fossil search logic.
* <b>Off-Line Access:</b> Because forum posts are synced along with
all other artifacts, you can search the forum, or add new posts, or
edit existing posts, all while off-line.
* <b>Automatically Cross-Referenced To Other Fossil Artifacts:</b> Because forum
posts are normal Fossil artifacts, you can link from them to
other Fossil artifacts (check-ins, wiki, tickets) and from those other
artifacts to forum posts. The reverse links are recognized and
displayed automatically on the receiver.
* <b>Malefactor Resistant:</b> Because Fossil accepts forum posts
only via the web UI, it is more resistent to spam. Passers-by
can post to the forum anonymously (subject to moderation), without
the hassle of a sign-up process.
* <b>Distributed and Tamper-Proof:</b> Posts are stored in the Fossil
repository using the same [./fileformat.wiki | DAG/Merkle-tree design]
that Fossil uses to store your check-ins, wiki documents, etc.
Forum posts sync to cloned repositories.
<h2>Example Installations</h2>
Both the [forum:/forum|Fossil project itself] and the
[https://sqlite.org/forum/forum|SQLite project] use the Fossil forum in place
of mailing lists. The forum has worked well on both projects. The ability
to post anonymously provides a low-resistance path for people to report
problems, resulting in more problems being reported and fixed.
The ability to moderate and amend forum posts means that the
forums contain better information. And backups and archives
are as easy as running "clone".
Both Fossil and SQLite keep their forums as separate repositories.
But there is no requirement to do this. A forum can be coresident in
the same repository with the source code.
<h2 id="setup">Setting up a Fossil Forum</h2>
<h3 id="caps">Capabilities</h3>
By default, no Fossil user has permission to use the forums except for
users with Setup and Admin capabilities, which get these as part of the
large package of other capabilities they get.
For public Fossil repositories that wish to accept new users without
involving a human, go into Admin → Access and enable the "Allow
users to register themselves" setting. You may also wish to give users
in [./caps/#ucat | the <tt>anonymous</tt> user category] the
<b>[./caps/ref.html#2 | RdForum]</b> and
<b>[./caps/ref.html#3 | WrForum]</b>
capabilities: this allows people to post without creating an account
simply by solving [./antibot.wiki | a simple CAPTCHA].
For a private repository, you probably won't want to give the
<tt>anonymous</tt> user any forum access, but you may wish to give the
<b>RdForum</b> capability to users in the <tt>reader</tt> category.
For either type of repository, you are likely to want to give at least
the <b>[./caps/ref.html#4 | WrTForum]</b> capability to users in the <tt>developer</tt>
category. If you did not give the <b>RdForum</b> capability to
<tt>anonymous</tt> above, you should give <tt>developer</tt> that
capability here if you choose to give it <b>WrForum</b> or
<b>WrTForum</b> capability.
If you want to use the email alert feature, by default only those
users in the Setup and Admin user categories can make use of it. Grant
the <b>[./caps/ref.html#7 | EmailAlert]</b> capability to give others access to this feature.
Alternately, you can handle alert signups outside of Fossil, with
a Setup or Admin users manually signing users up via Admin →
Notification. You'll want to grant this capability to the
<tt>nobody</tt> user category if you want anyone to sign up without any
restrictions. Give it to <tt>anonymous</tt> instead if you want the
user to solve a simple CAPTCHA before signing up. Or, give it to
<tt>reader</tt> or <tt>developer</tt> if you want only users with Fossil
logins to have this ability. (That's assuming you give one or both of
these capabilities to every user on your Fossil repository.)
By following this advice, you should not need to tediously add
capabilities to individual accounts except in atypical cases, such as
to grant the <b>[./caps/ref.html#5 | ModForum]</b> capability to an uncommonly
highly-trusted user.
<h3 id="skin">Skin Setup</h3>
If you create a new Fossil repository with version 2.7 or newer, its
default skin is already set up correctly for typical forum
configurations.
If you have an existing repository, you have two choices if you want its
skin to be upgraded to support forums:
<ol>
<li>Go into Admin → Skins and switch from your current skin to
one of the stock skins. If you were on a stock skin, just switch away
from your current one to the actual stock skin, since they will be
different after the upgrade.</li>
<li>If you have local customization that you do not want to throw
away, you can use the diff feature of Fossil's skin editor to show how
the skins differ.</li>
</ol>
The remainder of this section summarizes the differences you're expected
to see when taking option #2.
The first thing is that you'll need to add something like the following
to the Header part of the skin to create the navbar link:
<verbatim>
if {[anycap 23456] || [anoncap 2] || [anoncap 3]} {
menulink /forum Forum
}
</verbatim>
These rules say that any logged-in user with any [./caps/ref.html#2 |
forum-related capability] or an anonymous user <b>RdForum</b> or
<b>WrForum</b> capability will see the "Forum" navbar
link, which just takes you to <tt>/forum</tt>.
The exact code you need here varies depending on which skin you're
using. Follow the style you see for the other navbar links.
The new forum feature also brings many new CSS styles to the table. If
you're using the stock skin or something sufficiently close, the changes
may work with your existing skin as-is. Otherwise, you might need to
adjust some things, such as the background color used for the selected
forum post:
<verbatim>
div.forumSel {
background-color: rgba(0, 0, 0, 0.05);
}
</verbatim>
That overrides the default — a hard-coded light cyan — with a 95%
transparent black overlay instead, which simply darkens your skin's
normal background color underneath the selected post. That should work
with almost any background color except for very dark background colors.
For dark skins, an inverse of the above trick will work better:
<verbatim>
div.forumSel {
background-color: rgba(255, 255, 255, 0.05);
}
</verbatim>
That overlays the background with 5% white to lighten it slightly.
Another new forum-related CSS style you might want to reflect into your
existing skin is:
<verbatim>
div.forumPosts a:visited {
color: #6A7F94;
}
</verbatim>
This changes the clicked-hyperlink color for the forum post links on the
main <tt>/forum</tt> page only, which allows your browser's history
mechanism to show which threads a user has read and which not. The link
color will change back to the normal link color — indicating "unread" —
when a reply is added to an existing thread because that changes where
the link from the <tt>/forum</tt> page points, taking you to the newest
post in the thread.
The color given above is suitable for the stock skin.
Beware that when changing this example, there are some
[https://hacks.mozilla.org/2010/03/privacy-related-changes-coming-to-css-vistited/
| stringent restrictions] in modern browsers to prevent snoopy web sites
from brute-forcing your browsing history. (See the link for the method,
which explains the restrictions.)
<h3 id="search">Enable Forum Search</h3>
One of the underlying assumptions of the forum feature is that you will
want to be able to search the forum archives, so the <tt>/forum</tt>
page always includes a search box. Since that depends on search being
enabled on the Fossil repository, Fossil warns that search is disabled
until you go into Admin → Search and enable the "Search Forum"
setting.
You may want to enable some of the other Fossil search features while
you're in there. All of this does come at some CPU and I/O cost, which
is why it's disabled by default.
<h3 id="sso">Single Sign-On</h3>
If you choose to host your discussion forums within the same repository
as your project's other Fossil-managed content, you inherently have a
single sign-on system. Contrast third-party mailing list and forum
software where you either end up with two separate user tables and
permission sets, or you must go to significant effort to integrate the
two login systems.
You may instead choose to host your forums in a Fossil repository
separate from your project's main Fossil repository. A good reason to do
this is that you have a public project where very few of those
participating in the forum have special capability bits for project
assets managed by Fossil, so you wish to segregate the two user sets.
Yet, what of the users who will have logins on both repositories? Some
users will be trusted with access to the project's main Fossil
repository, and these users will probably also participate in the
project's Fossil-hosted forum. Fossil has a feature to solve this
problem: [./caps/login-groups.md | login groups].
<h3 id="alerts">Email Alerts (a.k.a. Notifications)</h3>
Internet email service has become rather complicated since its initial
simple and insecure implementation decades ago. Fossil's role in all of
this is rather small at the moment, but the details of the integration
are complex enough to justify [./alerts.md | a separate document].
(The other reason that document is separate is that Fossil's email
alerts system also gets used by features of Fossil other than the
forum.)
<h2 id="access">Accessing the Forum</h2>
There are many paths to a repository's Fossil forum:

If you're using the default Fossil skin as shipped with Fossil
2.7+ or one [#skin | updated] to support it, there
is a Forum button in the navbar which appears for users able to
access the forum. With the default skin, that button will only
appear if the user's browser window is at least
1200 pixels wide. The
Fossil admin can adjust this limit in the skin's CSS section, down
near the bottom in the definition of the `wideonly` style.
</li>
<li>The other stock skins have this button in them as of 2.7 as well,
without the screen width restriction, since the navbar in those skins
wraps on narrow screens more gracefully than the default skin
does.</li>
<li>Users who set up their Fossil repository under prior versions and
who now have local skin changes they don't want to overwrite by
reverting to the stock 2.7 version of the skin they chose to start
with can easily [#skin | edit their skin] to include these links.</li>
<li>A "Forum" link appears in the drop-down panel when you click the
default skin's hamburger menu (☰) while logged in as any user
with one or more of the [#caps | user capabilities listed above].</li>
<li>That same link also appears on the repository's <tt>/sitemap</tt>
page, since it provides the content for the hamburger menu's
panel.</li>
</ul>
<h2 id="moderation">How Moderation Works</h2>
In this section, we're going to call all of the following a "forum
update:"
* create a new post
* reply to an existing post
* edit a post or reply
When a person with the normal <b>WrForum</b> capability
updates the forum, Fossil saves the update in its block chain, but this
update is impermanent because of two other table updates made at the
same time:
<ol>
<li>Fossil saves the update artifact's ID in its <tt>private</tt>
table, preventing Fossil from sending such artifacts to any of the
repository's clones. (This is the same mechanism behind
[./private.wiki | private branches].)</li>
<li>Fossil also adds a reference to that artifact in the
<tt>modreq</tt> table, which backs the moderation feature. This is
what causes Fossil to leave out the Reply button when rendering that
post's HTML in the forum's web interface.</li>
</ol>
When a moderator approves an update, Fossil deletes these table entries,
making the update [./shunning.wiki | semi-permanent]. This changes how Fossil renders the
HTML for that update. It also means the artifact will now sync to
users with <b>[./caps/ref.html#g | Clone]</b> capability.
When a forum user edits a moderator-approved artifact, what actually
happens under the hood is that Fossil writes another artifact to the
repository which refers to the original version as its parent, causing
Fossil UI to present the new version instead of the original. The
original version remains in the repository, just as with historical
checkins. The parent must remain in the repository for referential
integrity purposes.
When you "Delete" a moderator-approved post or reply through Fossil UI,
it's actually an edit with blank replacement content. The only way to
truly delete such artifacts is through [./shunning.wiki | shunning].
When a user with <b>WrTForum</b> capability
updates the forum, it happens in the same way except that Fossil skips
the <tt>private</tt> and <tt>modreq</tt> table insertions.
When a moderator rejects an update, that artifact is unceremoniously
removed from the tip of the block chain. This is safe because Fossil
prevents replies to a reply or post awaiting moderator approval, so
referential integrity cannot be harmed. Rejecting an edit is even
safer, since the original post remains behind, so that replies continue
to refer to that original post.
<h2 id="mod-user">Using the Moderation Feature</h2>
Having described all of the work that Fossil performs under the hood on
behalf of its users, we can now give the short list of work left for the
repository's administrators and moderators:
<ol>
<li>Add the <b>[./caps/ref.html#5 | ModForum]</b> capability to any of
your users who should have this ability. You don't need to do this
for any user with <b>[./caps/ref.html#s | Setup]</b> or
<b>[./caps/ref.html#a | Admin]</b> capability; it's
[/artifact/b16221ffb736caa2?ln=1246-1257 | already included].</li>
<li>When someone updates the forum, an entry will appear in the
timeline if the type filter is set to "Forum" or "Any Type". If that
user has only the <b>WrForum</b> capability, any
other user with the <b>ModForum</b> capability
will see a conditional link appear at the top of the main forum
page: "Moderation Requests". Clicking this takes the moderator to
the <tt>/modreq</tt> page. A moderator may wish to keep the main
forum page open in a browser tab, reloading it occasionally to see
when the "Moderation Requests" link reappears.</li>
<li>A moderator viewing an update pending moderation sees two
buttons at the bottom, "Approve" and "Reject" in place of the
"Delete" button that the post's creator sees. Beware that both
actions are durable and have no undo. Be careful!</li>
</ol>
<h2 id="close-post">Closing Forum Posts</h2>
As of version 2.23, the forum interface supports the notion of
"closing" posts. By default, only users with the [./caps/index.md|'s'
and 'a' capabilities] may close or re-open posts, or reply to closed
posts. If the [/help?cmd=forum-close-policy|forum-close-policy
configuration option] is enabled then users with
[./caps/index.md|forum-moderator permissions] may also perform those
actions.
Closing a post has the following implications:
* Only authorized users may edit or respond to such posts, recursively
through all responses of that post.
* Only authorized users may re-open a closed post.
A forum thread may be closed at any given point in the conversation,
not just the starting point of the thread, and affects that specific
post and all existing responses to it.
Note that closing a post is effectively an "advisory lock" and may be
bypassed. Any user, admin or otherwise, who can push changes to a
repository may bypass closure of a post by setting the appropriate
artifact tags on a local copy and pushing those changes to a remote
copy of the forum.
The option to close a post, permissions permitting, appears as a
"Close" button on the currently-selected post. If the selected post is
alread closed, a "Re-open" button will be shown instead. In order to
re-open a post, <em>the closed post itself</em> must be
selected. Selecting a response to that post, which is implicitly
closed by the closure of its parent, will <em>not</em> offer a re-open
option.
Though forum users are permitted to delete their own posts, they are
not permitted, without appropriate permissions, to close their own
posts. This is intentional, as closing one's own post can be used to
antagonize other forum users. For example, by posting something
trollish or highly controversial in nature and closing the post to
further responses.

<title>Checklist For Successful Open-Source Projects</title>
<nowiki>
This checklist is loosely derived from Tom "Spot" Callaway's Fail Score
blog post <a href="http://spot.livejournal.com/308370.html">
http://spot.livejournal.com/308370.html</a> (see also
<a href="http://www.theopensourceway.org/book/The_Open_Source_Way-How_to_tell_if_a_FLOSS_project_is_doomed_to_FAIL.html">[1]</a>).
Tom's original post assigned point scores to the various elements and
by adding together the individual points, the reader is supposed to be able
to judge the likelihood that the project will fail.
The point scores, and the items on the list, clearly reflect Tom's
biases and are not necessarily those of the larger open-source community.
Nevertheless, the policy of the Fossil shall be to strive for a perfect
score.
This checklist is an inversion of Tom's original post in that it strives to
say what the project should do in order to succeed rather than what it
should not do to avoid failure. The point values are omitted.

<h1>Integrating Fossil in the Microsoft Express 2010 IDE</h1>
<i>Contributed by Gilles Ganault on 2013-05-24.</i>
The Express version of Visual Studio doesn't support add-in's and plug-in's,
but it's not an issue since it's still possible to use Fossil through the
External Tools menu and Fossil is a CLI application anyway:
<ol type="1">
<li>Tools > Settings > Expert Settings</li>
<li>Tools > External Tools, where the items in this list map
to "External Tool X" that we'll add to our own Fossil
menu later: </li>
<ol type="1">
<li>Rename the default "[New Tool 1]" to eg.
"Commit" 2.
</li>
<li>Change Command to where Fossil is located eg.
"c:\fossil.exe"</li>
<li>Change Arguments to the required command, eg.
"commit -m".
The user will be prompted to type the comment that Commit expects</li>
<li>Set "Initial Directory" to point it to the work directory
where the source files are currently checked out
by Fossil (eg. c:\Workspace). It's also possible to use system
variables such as "$(ProjectDir)" instead of hard-coding the path</li>
<li>Check "Prompt for arguments", since Commit
requires typing a comment. Useless for commands like Changes
that don't require arguments</li>
<li>Uncheck "Close on Exit", so we can see what Fossil says
before closing the DOS box. Note that "Use Output Window"
will display the output in a child window within the IDE instead of
opening a DOS box</li>
<li>Click on OK</li>
</ol>
<li>Tools > Customize > Commands</li>
<ol type="1">
<li>With "Menu bar = Menu Bar" selected, click on "Add
New Menu". A new "Fossil" menu is displayed in the
IDE's menu bar</li>
<li>Click on "Modify Selection" to rename it
"Fossil", and...</li>
<li>Use the "Move Down" button to move it lower in
the list</li>
</ol>
<li>Still in Customize dialog: In the "Menu bar" combo, select
the new Fossil menu you just created, and Click on "Add Command...":
From Categories, select Tools, and select "External Command 1".
Click on Close. It's unfortunate that the IDE doesn't say which command
maps to "External Command X".</li>
</ol>

The truth, however, is *far stranger than that.* This document introduces, at a relatively high level: 1) The underlying enduring and immutable data format, which is independent of any specific storage engine. 2) The `blob` table: Fossil's single point of SCM-relevant data storage. 3) The transformation of (1) from its immutable raw form to a *transient* database-friendly form. 4) Some of the consequences of this model. # Part 1: Artifacts ```pikchr center AllObjects: [ A: file "Artifacts" fill lightskyblue; down; move to A.s; move 50%; F: file "Client" "files"; right; move 1; up; move 50%; B: cylinder "blob table" right; arrow from A.e to B.w; arrow from F.e to B.w; arrow dashed from B.e; C: box rad 0.1 "Crosslink" "process"; arrow AUX: cylinder "Auxiliary" "tables" arc -> cw dotted from AUX.s to B.s; ] # end of AllObjects ``` The centerpiece of Fossil's architecture is a data format which describes what we call "artifacts." Each artifact represents the state of one atomic unit of SCM-relevant data, such as a single checkin, a single wiki page edit, a single modification to a ticket, creation or cancellation of tags, and similar SCM constructs. In the cases of checkins and ticket updates, an artifact may record changes to multiple files resp. ticket fields, but the change as a whole is atomic. Though we often refer to both fossil-specific SCM data and client-side content as artifacts, this document uses the term artifact solely for the former purpose. From [the data format's main documentation][dataformat]: > The global state of a fossil repository is kept simple so that it > can endure in useful form for decades or centuries. A fossil > repository is intended to be readable, searchable, and extensible by > people not yet born. [dataformat]: ./fileformat.wiki This format has the following major properties: - It is <u>**syntactically simple**</u>, easily and efficiently parsable in any programming language. It is also entirely human-readable. - It is <u>**immutable**</u>. An artifact is identified by its unique hash value. Any modification to an artifact changes that hash, thereby changing its identity. - It is <u>**not generic**</u>. It is custom-made for its purpose and makes no attempt at providing a generic format. It contains *only* what it *needs* to function, with zero bloat. - It <u>**holds all SCM-relevant data except for client-level file content**</u>, the latter instead being referenced by their unique hash values. Storage of the client-side content is an implementation detail delegated to higher-level applications. - <u>**Auditability**</u>. By following the hash references in artifacts it is possible to unambiguously trace the origin of any modification to the SCM state. Combined with higher-level tools (specifically, Fossil's database), this audit trail can easily be traced both backwards and forwards in time, using any given version in the SCM history as a starting point. Notably, the artifact file format <u>does not</u>... - Specify any specific storage mechanism for the SCM's raw bytes, which includes both artifacts themselves and client-side file content. The file format refers to all such content solely by its unique hash value. - Specify any optimimizations such as storing file-level changes as deltas between two versions of that content. Such aspects are all considered to be implementation details of higher-level applications (be they in the main fossil binary or a hypothetical 3rd-party application), and have no effect on the underlying artifact data model. That said, in Fossil: - All raw byte content (artifacts and client files) is stored in the `blob` database table. - Fossil uses delta and zlib compression to keep the storage size of changes from one version of a piece of content to the next to a minimum. ## Sidebar: SCM-relevant vs Non-SCM-relevant State Certain data in Fossil are "SCM-relevant" and certain data are not. In short, SCM-relevant data are managed in a way consistent with controlled versioning of that data. Conversely, non-SCM-relevant data are essentially any state neither specified by nor unambiguously refererenced by the artifact file format and are therefore not versioned. SCM-relevant state includes: - Any and all data stored in the bodies of artifacts. This includes, but is not limited to: wiki/ticket/forum content, tags, file names and Fossil-side permissions, the name of each user who introduces any given artifact into the data store, the timestamp of each such change, the inheritance tree of checkins, and many other pieces of metadata. - Raw file content of versioned files. These data are external to artifacts, which refer to them by their hashes. How they are stored is not the concern of the data model, but (spoiler alert!) Fossil stores them in an SQLite database, one record per distinct hash, in its `blob` table (which we will cover more very soon). Non-SCM-relevant state includes: - Fossil's list of users and their metadata (permissions, email address, etc.). Artifacts themselves reference users only by their user names. Artifacts neither care whether, nor guarantee that, user "drh" in one artifact is in fact the same "drh" referenced in another artifact. - All Fossil UI configuration, e.g. the site's skin, config settings, and project name. - In short, any tables in a Fossil repository file except for the `blob` table. Most, but not all, of these tables are transient caches for the data specified by the artifact files (which are stored in the `blob` table), and can safely be destroyed and rebuilt from the collection of artifacts with no loss of state to the repository. *All* of them, except for `blob` and `delta`, can be destroyed with no loss of *SCM-relevant* data. ## Terminology Hair-splitting: Manifest vs. Artifact We sometimes refer to artifacts as "manifests," which is technically a term for artifacts which record checkins. The various other artifact types are arguably not "manifests," but are sometimes referred to as such because the internal APIs use that term. ## A Very Basic Example The following artifact, truncated for brevity, represents a typical checkin artifact (a.k.a. a manifest): ``` C Bug\sfix\sin\sthe\slocal\sdatabase\sfinder. D 2007-07-30T13:01:08 F src/VERSION 24bbb3aad63325ff33c56d777007d7cd63dc19ea F src/add.c 1a5dfcdbfd24c65fa04da865b2e21486d075e154 F src/blob.c 8ec1e279a6cd0cfd5f1e3f8a39f2e9a1682e0113 <SNIP> F www/selfcheck.html 849df9860df602dc2c55163d658c6b138213122f P 01e7596a984e2cd2bc12abc0a741415b902cbeea R 74a0432d81b956bfc3ff5a1a2bb46eb5 U drh Z c9dcc06ecead312b1c310711cb360bc3 ``` Each line is a single data record called a "card." The first letter of each line tells us the type of data stored on that line and the following space-separated tokens contain the data for that line. Tokens which themselves contain spaces (notably the checkin comment) have those escaped as `\s`. The raw text of wiki pages/comments, forum posts, and ticket bodies/comments is stored directly in the corresponding artifact, but is stored in a way which makes such escaping unnecessary. The hashes seen above are a critical component of the architecture: - The `F` (file) records refer to the content of those files by the hash of that content. Where that content is stored is *not* specified by the data model. - The `P` (parent) line is the hash code of the parent version (itself an artifact). - The `Z` line is a hash of all of the content of *this artifact* which precedes the `Z` line. Thus any change to the content of an artifact changes both the artifact's identity (its hash) and its `Z` value, making it impossible to inject modified artifacts into an existing artifact tree. - The `R` line is yet another consistency-checking hash which we won't go into here except to say that it's an internal consistency check/line of defense against modification of file content referenced by the artifact. # Part 2: The `blob` Table ```pikchr center AllObjects: [ A: file "Artifacts"; down; move to A.s; move 50%; F: file "Client" "files" fill lightskyblue; right; move 1; up; move 50%; B: cylinder "blob table" fill lightskyblue; right; arrow from A.e to B.w; arrow from F.e to B.w; arrow dashed from B.e; C: box rad 0.1 "Crosslink" "process"; arrow AUX: cylinder "Auxiliary" "tables" arc -> cw dotted from AUX.s to B.s; ] # end of AllObjects ``` The `blob` table is the core-most storage of a Fossil repository database, storing all SCM-relevant data (and *only* SCM-relevant data). Each row of this table holds a single artifact or the content for a single version of a single client-side file. Slightly truncated for clarity, its schema contains the following fields: - **`uuid`**: the hash code of the blob's contents. - **`rid`**: a unique integer key for this record. This is how the blob table is mapped to other (transient) tables, but the RIDs are specific to one given copy of a repository and must not be used for cross-repository referencing. The RID is a private/internal value of no use to a user unless they're building SQL queries for use with the Fossil db schema. - **`size`**: the size, in bytes, of the blob's contents, or -1 for "phantom" blobs (those which Fossil knows should exist because it's seen them referenced somewhere, but for which it has not been given any content). - **`content`**: the blob's raw content bytes, with the caveat that Fossil is free to store it in an "alternate representation." Specifically, the `content` field often holds a zlib-compressed delta from a previous version of the blob's content (a separate entry in the `blob` table), and an auxiliary table named `delta` maps such blobs to their previous versions, such that Fossil can reconstruct the real content from them by applying the delta to its previous version (and such deltas may be chained). Thus extraction of the content from this field cannot be performed via vanilla SQL, and requires a Fossil-specific function which knows how to convert any internal representations of the content to its original form. ## Sidebar: How does `blob` Distinguish Between Artifacts and Client Content? Notice that the `blob` table has no flag saying "this record is an artifact" or "this record is client data." Similarly, there is no place in the database dedicated to keeping track of which `blob` records are artifacts and which are file content. That said, (A) the type of a blob can be implied via certain table relationships and (B) the `event` table (the `/timeline`'s main data source) incidentally has a list of artifacts and their sub-types (checkin, wiki, tag, etc.). However, given that all of those relationships, including the timeline, are *transient*, how can Fossil distinguish between the two types of data? Fossil's artifact format is extremely rigid and is *strictly* enforced internally, with zero room provided for leniency. Every artifact which is internally created is re-parsed for validity before it is committed to the database, making it impossible that Fossil can inject an invalid artifact into the repository. Because of the strictness of the artifact parser, the chances that any given piece of arbitrary client data could be successfully parsed as an artifact, even if it is syntactically 99% similar to an artifact, are *effectively zero*. Thus Fossil's rule of interpreting the contents of the blob table is: if it can be parsed as an artifact, it *is* an artifact, else it is opaque client-side data. That rule is most often relevant in operations like `rebuild` and `reconstruct`, both of which necessarily have to sort out artifacts and non-artifact blobs from arbitrary collections of blobs. It is, in fact, possible to store an artifact unrelated to the current repository in that repository, and it *will be parsed and processed as an artifact* (see below), but it likely refers to other artifacts or blobs which are not part of the current repository, thereby possibly introducing "strange" data into the UI. If this happens, it's potentially slightly confusing but is functionally harmless. # Part 3: Crosslinking ```pikchr center AllObjects: [ A: file "Artifacts"; down; move to A.s; move 50%; F: file "Client" "files"; right; move 1; up; move 50%; B: cylinder "blob table" right; arrow from A.e to B.w; arrow from F.e to B.w; arrow dashed from B.e; C: box rad 0.1 "Crosslink" "process" fill lightskyblue; arrow AUX: cylinder "Auxiliary" "tables" fill lightskyblue; arc -> cw dotted from AUX.s to B.s; ] # end of AllObjects ``` Once an artifact is stored in the `blob` table, how does one perform SQL queries against its plain-text format? In short: *One Does Not Simply Query the Artifacts*. Crosslinking, as its colloquially known, is a one-way processing step which transforms an immutable artifact's state into something database-friendly. Crosslinking happens automatically every time Fossil generates, or is given, a new artifact. Crosslinking of any given artifact may update many different auxiliary tables, *all* of which are transient in the sense that they may be destroyed and then recreated by crosslinking all artifacts from the `blob` table (which is exactly what the `rebuild` command does). The overwhelming majority of individual database records in any Fossil repository are found in these transient auxiliary tables, though the `blob` table tends to account for the overwhelming majority of a repository's disk space. This approach to mapping data from artifacts to the db gives Fossil the freedom to change its database model, effectively at will, with minimal client-side disruption (at most, a call to `rebuild`). This allows, for example, Fossil to take advantage of new improvements in sqlite without affecting compatibility with older repositories. Auxiliary tables hold data mappings such as: - Child/parent relationships of checkins. (The `plink` table.) - Records of file names and changes to files. (The `mlink` and `filename` tables.) - Timeline entries. (The `event` table.) And numerous other bits and pieces. The many auxiliary tables maintained by the app-level code reference the `blob` table via its RID field, as that's far more efficient than using hashes (`blob.uuid`) as foreign keys. The contexts of those auxiliary data unambiguously tell us whether the referenced blobs are artifacts or file content, so there is no efficiency penalty there for hosting both opaque blobs and artifacts in the `blob` table. The complete SQL schemas for the core-most auxiliary tables can be found at: [](/finfo/src/schema.c?ci=trunk) Noting, however, that all database tables are effectively internal APIs, with no API stability guarantees and subject to change at any time. Thus their structures generally should not be relied upon in client-side scripts. # Part 4: Implications and Consequences of the Model *Some* of the implications and consequences of Fossil's data model combined with the higher-level access via SQL include: - **Provable immutability of history.** Fossil offers only one option for modifying history: "shunning" is the forceful removal of an artifact from the `blob` table and the creation of a db record stating that the shunned hash may no longer be synced into this repository. Shunning effectively leaves a hole in the SCM history, and is only intended to be used for removal of illegal, dangerous, or private information which should never have been added to the repository. - **Complete separation of SCM-relevant data and app-level data structures**. This allows the application to update its structures at will without significant backwards-compatibility concerns. In Fossil's case, "data structures" primarily refers to the SQL schema. Bringing a given repository schema up to date vis a vis a given fossil binary version simply means rebuilding the repository with that fossil binary. There are exceptionally rare cases, namely the switch from SHA1 to SHA3-256 ushered in with Fossil 2.0, which can lead to true incompatibility. e.g. a Fossil 1.x client cannot use a repository database which contains SHA3 hashes, regardless of a rebuild. - **Two-way compatibility with other hypothetical clients** which also implement the same underlying data model. So far there are none, but it's conceivably possible. - **Provides a solid basis for reporting.** Fossil's real-time metrics and reporting options are arguably the most powerful and flexible yet seen in an SCM. - Very probably several more things. |

<title>Fossil Versus Git</title>
<h2>1.0 Don't Stress!</h2>
The feature sets of Fossil and [http://git-scm.com | Git] overlap in
many ways. Both are
[https://en.wikipedia.org/wiki/Distributed_version_control | distributed
version control systems] which store a tree of check-in objects to a
local repository clone. In both systems, the local clone starts out as a
full copy of the remote parent. New content gets added to the local
clone and then later optionally pushed up to the remote, and changes to
the remote can be pulled down to the local clone at will. Both systems
offer diffing, patching, branching, merging, cherry-picking, bisecting,
private branches, a stash, etc.
Fossil has inbound and outbound Git conversion features, so if you start
out using one DVCS and later decide you like the other better, you can
easily [./inout.wiki | move your version-controlled file content].¹
In this document, we set all of that similarity and interoperability
aside and focus on the important differences between the two, especially
those that impact the user experience.
Keep in mind that you are reading this on a Fossil website, and though
we try to be fair, the information here
might be biased in favor of Fossil, if only because we spend most of our
time using Fossil, not Git. Ask around for second opinions from
people who have used <em>both</em> Fossil and Git.
If you want a more practical, less philosophical guide to moving from
Git to Fossil, see our [./gitusers.md | Git to Fossil Translation Guide].

<h3 id="features">2.1 Featureful</h3>
Git provides file versioning services only, whereas Fossil adds
an integrated [./wikitheory.wiki | wiki],
[./bugtheory.wiki | ticketing & bug tracking],
[./embeddeddoc.wiki | embedded documentation],
[./event.wiki | technical notes], a [./forum.wiki | web forum],

These additional capabilities are available for Git as 3rd-party
add-ons, but with Fossil they are integrated into
the design, to the point that it approximates
"[https://github.com/ | GitHub]-in-a-box."
Even if you only want straight version control, Fossil has affordances
not available in Git.
For instance, Fossil can do operations over all local repo clones and
check-out directories with a single command. You can say "<tt>fossil
all sync</tt>" on a laptop prior to taking it off the network hosting
those repos, as before going on a trip. It doesn't matter if those
repos are private and restricted to your company network or public
Internet-hosted repos, you get synced up with everything you need while
off-network.
You get the same capability with several other Fossil
sub-commands as well, such as "<tt>fossil all changes</tt>" to get a list of files
that you forgot to commit prior to the end of your working day, across
all repos.
Whenever Fossil is told to modify the local checkout in some destructive
way ([/help?cmd=rm|fossil rm], [/help?cmd=update|fossil update],
[/help?cmd=revert|fossil revert], etc.) Fossil remembers the prior state
and is able to return the check-out directory to that state with a
<tt>fossil undo</tt> command. While you cannot undo a commit in Fossil
— [#history | on purpose!] — as long as the change remains confined to
the local check-out directory only, Fossil makes undo
[https://git-scm.com/book/en/v2/Git-Basics-Undoing-Things|easier than in
Git].
For developers who choose to self-host projects rather than rely on a
3rd-party service such as GitHub, Fossil is much easier to set up:
the stand-alone Fossil executable together with a [./server/any/cgi.md|2-line CGI script]
suffice to instantiate a full-featured developer website. To accomplish
the same using Git requires locating, installing, configuring, integrating,
and managing a wide assortment of separate tools. Standing up a developer
website using Fossil can be done in minutes, whereas doing the same using
Git requires hours or days.
Fossil is small, complete, and self-contained. If you clone
[https://github.com/git/git|Git's self-hosting repository], you get just
Git's source code. If you clone Fossil's self-hosting repository, you
get the entire Fossil website — source code, documentation, ticket
history, and so forth.² That means you get a copy of this very article
and all of its historical versions, plus the same for all of the other
public content on this site.
<h3 id="selfcontained" name="selfcontained">2.2 Self Contained</h3>
Git is actually a collection of many small tools, each doing one small
part of the job, which can be recombined (by experts) to perform
powerful operations. Git has a lot of complexity and many dependencies,
so that most people end up installing it via some kind of package
manager, simply because the creation of complicated binary packages is
best delegated to people skilled in their creation. Normal Git users are
not expected to build Git from source and install it themselves.
Fossil is a single self-contained stand-alone executable which
depends only on common platform libraries in its default configuration.
To install one of [https://fossil-scm.org/home/uv/download.html | our
precompiled binaries], unpack the executable from the archive and put it
somewhere in your <tt>PATH</tt>. To uninstall it, delete the executable.
This policy is particularly useful when running Fossil inside a
restrictive container, anything from [./chroot.md | classic chroot
jails] to modern [https://en.wikipedia.org/wiki/OS-level_virtualization
| OS-level virtualization mechanisms] such as
[https://en.wikipedia.org/wiki/Docker_(software) | Docker].
Our [./containers.md | stock container image] is under 8 MB when
uncompressed and running. It contains nothing but a single
statically-linked binary.
If you build a dynamically linked binary instead, Fossil's on-disk size
drops to around 6 MB, and it's dependent only on widespread
platform libraries with stable ABIs such as glibc, zlib, and openssl.
Full static linking is easier on Windows, so our precompiled Windows
binaries are just a ZIP archive
containing only "<tt>fossil.exe</tt>". There is no "<tt>setup.exe</tt>"
to run.
Fossil is easy to build from sources. Just run
"<tt>./configure && make</tt>" on POSIX systems and
"<tt>nmake /f Makefile.msc</tt>" on Windows.
Contrast a basic installation of Git, which takes up about
15 MiB on Debian 10 across 230 files, not counting the contents of
<tt>/usr/share/doc</tt> or <tt>/usr/share/locale</tt>. If you need to
deploy to any platform where you cannot count on facilities like the POSIX
shell, Perl interpreter, and Tcl/Tk platform needed to fully use Git
as part of the base platform, the full footprint of a Git installation
extends to more like 45 MiB and thousands of files. This complicates
several common scenarios: Git for Windows, chrooted Git servers,
Docker images...
Some say that Git more closely adheres to the Unix philosophy,
summarized as "many small tools, loosely joined," but we have many
examples of other successful Unix software that violates that principle
to good effect, from Apache to Python to ZFS. We can infer from that
that this is not an absolute principle of good software design.
Sometimes "many features, tightly-coupled" works better. What actually
matters is effectiveness and efficiency. We believe Fossil achieves
this.
The above size comparisons aren't apples-to-apples anyway. We've
compared the size of Fossil with all of its [#features | many built-in
features] to a fairly minimal Git installation. You must add a lot of
third-party software to Git to give it a Fossil-equivalent feature set.
Consider [https://about.gitlab.com/|GitLab], a third-party extension to
Git wrapping it in many features, making it roughly Fossil-equivalent,
though [https://docs.gitlab.com/ee/install/requirements.html|much more
resource hungry] and hence more costly to run than the equivalent Fossil
setup. [https://hub.docker.com/r/gitlab/gitlab-ce/ | The official GitLab
Community Edition container] currently clocks in at 2.66Â GiB!
GitLab's requirements are easy to accept when you're dedicating
a local rack server or blade to it, since its minimum requirements are
more or less a description of the smallest
thing you could call a "server" these days, but when you go to host that
in the cloud, you can expect to pay about 8 times as much to comfortably host
GitLab as for Fossil.³ This difference is largely due to basic
technology choices: Ruby and PostgreSQL vs C and SQLite.
The Fossil project itself is [./selfhost.wiki|hosted on a small and
inexpensive VPS]. A bare-bones $5/month VPS or a
spare Raspberry Pi is sufficient to run a full-up project
site, complete with tickets, wiki, chat, and forum, in addition to
being a code repository.
<h3 id="durable" name="database">2.3 Query Language</h3>
The baseline data structures for Fossil and Git are the same, modulo
formatting details. Both systems manage a
[https://en.wikipedia.org/wiki/Directed_acyclic_graph | directed acyclic
graph] (DAG) of [https://en.wikipedia.org/wiki/Merkle_tree | Merkle
tree] structured check-in objects.
Check-ins are identified by a cryptographic hash of the check-in
contents, and each check-in refers to its parent via the parent's hash.
The difference is that Git stores its objects as individual files in the
<tt>.git</tt> folder or compressed into bespoke key/value
[https://git-scm.com/book/en/v2/Git-Internals-Packfiles|pack-files],
whereas Fossil stores its objects in a [https://www.sqlite.org/|SQLite]
database file which provides ACID transactions and a high-level query
language.
This difference is more than an implementation detail. It has important
practical consequences.
One notable consequence is that it is difficult to find the descendants
of check-ins in Git.
One can easily locate the ancestors of a particular Git check-in
by following the pointers embedded in the check-in object, but it is
difficult to go the other direction and locate the descendants of a
check-in. It is so difficult, in fact, that neither native Git nor
GitHub provide this capability short of crawling the
[https://www.git-scm.com/docs/git-log|commit log]. With Fossil,
on the other hand, finding descendants is a simple SQL query.
It is common in Fossil to ask to see
[/timeline?df=release&y=ci|all check-ins since the last release].
Git lets you see "what came before". Fossil makes it just as
easy to also see "what came after".
Leaf check-ins in Git that lack a "ref" become "detached," making them
difficult to locate and subject to garbage collection. This
[http://gitfaq.org/1/01/what-is-a-detached-head/|detached head
state] problem has caused grief for
[https://www.google.com/search?q=git+detached+head+state | many
Git users]. With
Fossil, detached heads are simply impossible because we can always find
our way back into the Merkle tree using one or more of the relations
in the SQL database.
The SQL query capabilities of Fossil make it easier to track the
changes for one particular file within a project. For example,
you can easily find
[/finfo/www/fossil-v-git.wiki|the complete edit history of this one document],
or even
[/finfo/www/fossil-v-git.wiki?ubg|the same history color-coded by committer],
Both questions are simple SQL query in Fossil, with procedural code
only being used to format the result for display.
The same result could be obtained from Git, but because the data is
in a key/value store, much more procedural code has to be written to
walk the data and compute the result. And since that is a lot more
work, the question is seldom asked.
The ease of querying Fossil data using SQL means that status or
history information about the project under management is easier
to obtain. Being easier means that it is more likely to happen.
Fossil reports tend to be more detailed and useful.
Compare [/timeline?c=6df7a853ec16865b|this Fossil timeline]
to
[https://github.com/drhsqlite/fossil-mirror/commits/master?after=f720c106d297ca1f61bccb30c5c191b88a626d01+34 |
its closest equivalent in GitHub]. Judge for yourself: which of those
reports is more useful to a developer trying to understand what happened?
The bottom line is that even though Fossil and Git are built around
the same low-level data structure, the use of SQL
to query this data makes the data more accessible in Fossil, resulting
in more detailed information being available to the user. This
improves situational awareness and makes working on the project
easier.
<h3 id="portable">2.4 Portable</h3>
Fossil is largely written in ISO C, almost purely conforming to the
original 1989 standard. We make very little use of
[https://en.wikipedia.org/wiki/C99|C99], and we do not knowingly make
any use of
[https://en.wikipedia.org/wiki/C11_(C_standard_revision)|C11]. Fossil
does call POSIX and Windows APIs where necessary, but it's about
as portable as you can ask given that ISO C doesn't define all of the
facilities Fossil needs to do its thing. (Network sockets, file locking,
etc.) There are certainly well-known platforms Fossil hasn't been ported
to yet, but that's most likely due to lack of interest rather than
inherent difficulties in doing the port. We believe the most stringent
limit on its portability is that it assumes at least a 32-bit CPU and
several megs of flat-addressed memory.â´ Fossil isn't quite as
[https://www.sqlite.org/custombuild.html|portable as SQLite], but it's
close.
Over half of the C code in Fossil is actually an embedded copy of the
current version of SQLite. Much of what is Fossil-specific after you set
SQLite itself aside is SQL code calling into SQLite. The number of lines
of SQL code in Fossil isn't large by percentage, but since SQL is such
an expressive, declarative language, it has an outsized contribution to
Fossil's user-visible functionality.
Fossil isn't entirely C and SQL code. Its web UI [./javascript.md |
uses JavaScript where
necessary]. The server-side
UI scripting uses a custom minimal
[https://en.wikipedia.org/wiki/Tcl|Tcl] dialect called
[https://fossil-scm.org/xfer/doc/trunk/www/th1.md|TH1], which is
embedded into Fossil itself. Fossil's build system and test suite are
largely based on Tcl.âµ All of this is quite portable.
About half of Git's code is POSIX C, and about a third is POSIX shell
code. This is largely why the so-called "Git for Windows" distributions
(both [https://git-scm.com/download/win|first-party] and
[https://gitforwindows.org/|third-party]) are actually an
[https://www.msys2.org/wiki/Home/|MSYS POSIX portability environment] bundled
with all of the Git stuff, because it would be too painful to port Git
natively to Windows. Git is a foreign citizen on Windows, speaking to it
only through a translator.â¶
While Fossil does lean toward POSIX norms when given a choice — LF-only
line endings are treated as first-class citizens over CR+LF, for example
— the Windows build of Fossil is truly native.
The third-party extensions to Git tend to follow this same pattern.
[https://docs.gitlab.com/ee/install/install_methods.html#microsoft-windows |
GitLab isn't portable to Windows at all],
for example. For that matter, GitLab isn't even officially supported on
macOS, the BSDs, or uncommon Linuxes! We have many users who regularly
build and run Fossil on all of these systems.
<h3 id="vs-linux">2.5 Linux vs. SQLite</h3>
Fossil and Git promote different development styles because each one was
specifically designed to support the creator's main software
development project: [https://en.wikipedia.org/wiki/Linus_Torvalds|Linus
Torvalds] designed Git to support development of
[https://www.kernel.org/|the Linux kernel], and
[https://en.wikipedia.org/wiki/D._Richard_Hipp|D. Richard Hipp] designed
Fossil to support the development of [https://sqlite.org/|SQLite].
Both projects must rank high on any objective list of "most
important FOSS projects," yet these two projects are almost entirely unlike
one another, so it is natural that the DVCSes created to support these
projects also differ in many ways.
In the following sections, we will explain how four key differences
between the Linux and SQLite software development projects dictated the
design of each DVCS's low-friction usage path.
When deciding between these two DVCSes, you should ask yourself, "Is my
project more like Linux or more like SQLite?"
<h4 id="devorg">2.5.1 Development Organization</h4>
Eric S. Raymond's seminal essay-turned-book
"[https://en.wikipedia.org/wiki/The_Cathedral_and_the_Bazaar|The
Cathedral and the Bazaar]" details the two major development
organization styles found in
[https://en.wikipedia.org/wiki/Free_and_open-source_software|FOSS]
projects. As it happens, Linux and SQLite fall on opposite sides of this
dichotomy. Differing development organization styles dictate a different
design and low-friction usage path in the tools created to support each
project.
Git promotes the Linux kernel's bazaar development style, in which a
loosely-associated mass of developers contribute their work through
[https://git-scm.com/book/en/v2/Distributed-Git-Distributed-Workflows#_dictator_and_lieutenants_workflow|a
hierarchy of lieutenants] who manage and clean up these contributions
for consideration by Linus Torvalds, who has the power to cherry-pick
individual contributions into his version of the Linux kernel. Git
allows an anonymous developer to rebase and push specific locally-named
private branches, so that a Git repo clone often isn't really a clone at
all: it may have an arbitrary number of differences relative to the
repository it originally cloned from. Git encourages siloed development.
Select work in a developer's local repository may remain private
indefinitely.
All of this is exactly what one wants when doing bazaar-style
development.
Fossil's normal mode of operation differs on every one of these points,
with the specific designed-in goal of promoting SQLite's cathedral
development model:
* <b>Personal engagement:</b> SQLite's developers know each
other by name and work together daily on the project.
* <b>Trust over hierarchy:</b> SQLite's developers check
changes into their local repository, and these are immediately and
automatically synchronized up to the central repository; there is no
"[https://git-scm.com/book/en/v2/Distributed-Git-Distributed-Workflows#_dictator_and_lieutenants_workflow|dictator
and lieutenants]" hierarchy as with Linux kernel contributions. D.
Richard Hipp rarely overrides decisions made by those he has trusted
with commit access on his repositories. Fossil allows you to give
[./caps/admin-v-setup.md|some users] more power over what
they can do with the repository, but Fossil [./caps/index.md#ucap |
only loosely supports] the enforcement of a development organization's
social and power hierarchies. Fossil is a great fit for
[https://en.wikipedia.org/wiki/Flat_organization|flat
organizations].
* <b>No easy drive-by contributions:</b> Git
[https://www.git-scm.com/docs/git-request-pull|pull requests] offer
a low-friction path to accepting
[https://www.jonobacon.com/2012/07/25/building-strong-community-structural-integrity/|drive-by
contributions]. Fossil's closest equivalents are its unique
[/help?cmd=bundle|bundle] and [/help?cmd=patch|patch] features, which require higher engagement
than firing off a PR.â· This difference comes directly from the
initial designed purpose for each tool: the SQLite project doesn't
accept outside contributions from previously-unknown developers, but
the Linux kernel does.
* <b>No rebasing:</b> When your local repo clone syncs changes
up to its parent, those changes are sent exactly as they were
committed locally. [#history|There is no rebasing mechanism in
Fossil, on purpose.]
* <b>Sync over push:</b> Explicit pushes are uncommon in
Fossil-based projects: the default is to rely on
[/help?cmd=autosync|autosync mode] instead, in which each commit
syncs immediately to its parent repository. This is a mode so you
can turn it off temporarily when needed, such as when working
offline. Fossil is still a truly distributed version control system;
it's just that its starting default is to assume you're rarely out
of communication with the parent repo.
<br><br>
This is not merely a reflection of modern always-connected computing
environments. It is a conscious decision in direct support of
SQLite's cathedral development model: we don't want developers going
dark, then showing up weeks later with a massive bolus of changes
for us to integrate all at once.
[https://en.wikipedia.org/wiki/Jim_McCarthy_(author)|Jim McCarthy]
put it well in his book on software project management,
<i>[https://www.amazon.com/dp/0735623198/|Dynamics of Software
Development]</i>: "[https://www.youtube.com/watch?v=oY6BCHqEbyc|Beware
of a guy in a room]."
* <b>Branch names sync:</b> Unlike in Git, branch names in
Fossil are not purely local labels. They sync along with everything
else, so everyone sees the same set of branch names. Fossil's design
choice here is a direct reflection of the Linux vs. SQLite project
outlook: SQLite's developers collaborate closely on a single
coherent project, whereas Linux's developers go off on tangents and
occasionally send selected change sets to each other.
* <b>Private branches are rare:</b>
[/doc/trunk/www/private.wiki|Private branches exist in Fossil], but
they're normally used to handle rare exception cases, whereas in
many Git projects, they're part of the straight-line development
process.
* <b>Identical clones:</b> Fossil's autosync system tries to
keep each local clone identical to the repository it cloned
from.
Where Git encourages siloed development, Fossil fights against it.
Fossil places a lot of emphasis on synchronizing everyone's work and on
reporting on the state of the project and the work of its developers, so
that everyone — especially the project leader — can maintain a better
mental picture of what is happening, leading to better situational
awareness.
By contrast, "…[https://docs.github.com/en/get-started/quickstart/contributing-to-projects|forking is
at the core of social coding at GitHub]". As of January 2022,
[https://github.com/search?q=is:public|Github hosts 47 million distinct
software projects], most of which were created by forking a
previously-existing project. Since this is
[https://evansdata.com/reports/viewRelease.php?reportID=9 | roughly
twice the number of developers in the world], it beggars belief that
most of these forks are still under active development. The vast bulk
of these must be abandoned one-off efforts. This is part of the nature
of bazaar style development.
You can think about this difference in terms of
[https://en.wikipedia.org/wiki/Feedback | feedback loop size], which we
know from the mathematics of
[https://en.wikipedia.org/wiki/Control_theory | control theory] to
directly affect the speed at which any system can safely make changes.
The larger the feedback loop, the slower the whole system must run in
order to avoid loss of control. The same concept shows up in other
contexts, such as in the [https://en.wikipedia.org/wiki/OODA_loop | OODA
loop] concept.
Committing your changes to private branches in order to delay a public
push to the parent repo increases the size of your collaborators'
control loops, either causing them to slow their work in order to safely
react to your work, or to over-correct in response to each change.
Each DVCS can be used in the opposite style, but doing so works against
their low-friction paths.
<h4 id="scale">2.5.2 Scale</h4>
The Linux kernel has a far bigger developer community than that of
SQLite: there are thousands and thousands of contributors to Linux, most
of whom do not know each other's names. These thousands are responsible
for producing roughly 89× more code than is in SQLite. (10.7
[https://en.wikipedia.org/wiki/Source_lines_of_code|MLOC] vs. 0.12 MLOC
according to [https://dwheeler.com/sloccount/|SLOCCount].) The Linux
kernel and its development process were already uncommonly large back in
2005 when Git was designed, specifically to support the consequences of
having such a large set of developers working on such a large code base.
95% of the code in SQLite comes from just four programmers, and 64% of
it is from the lead developer alone. The SQLite developers know each
other well and interact daily. Fossil was designed for this development
model.
When choosing your DVCS, we think you should ask yourself whether the
scale of your software configuration management problems is closer to
those Linus Torvalds designed Git to cope with or whether your work's
scale is closer to that of SQLite, for which D. Richard Hipp designed
Fossil. An [https://en.wikipedia.org/wiki/Impact_wrench|automotive air
impact wrench] running at 8000 RPM driving an M8 socket-cap bolt at 16
cm/s is not the best way to hang a picture on the living room wall.
Fossil works well for projects several times the size of SQLite,
[https://core.tcl-lang.org/tcl/ | such as Tcl], with a repository over
twice the size and with many more core committers.
<h4 id="branches">2.5.3 Individual Branches vs. The Entire Change History</h4>
Both Fossil and Git store history as a directed acyclic graph (DAG)
of changes, but Git tends to focus more on individual branches of
the DAG, whereas Fossil puts more emphasis on the entire DAG.
For example, the default behavior in Git is to only synchronize
a single branch, whereas with Fossil the only sync option is to
sync the entire DAG. Git commands,
GitHub, and GitLab tend to show only a single branch at
a time, whereas Fossil usually shows all parallel branches at
once. Git has commands like "rebase" that help keep all relevant
changes on a single branch, whereas Fossil encourages a style of
many concurrent branches constantly springing into existence,
undergoing active development in parallel for a few days or weeks, then
merging back into the main line and disappearing.
This difference in emphasis arises from the different purposes of
the two systems. Git focuses on individual branches, because that
is exactly what you want for a highly-distributed bazaar-style project
such as Linux. Linus Torvalds does not want to see every check-in
by every contributor to Linux: such extreme visibility does not scale
well. Contrast Fossil, which was written for the cathedral-style SQLite project
and its handful of active committers. Seeing all
changes on all branches all at once helps keep the whole team
up-to-date with what everybody else is doing, resulting in a more
tightly focused and cohesive implementation.
Parts of this section are [https://fossil-scm.org/forum/forumpost/5961e969fa|disputed]
by [https://github.com/olorin37|Jakub A. G.].
<h3 id="checkouts">2.6 One vs. Many Check-outs per Repository</h3>
Because Git commingles the repository data with the initial checkout of
that repository, the default mode of operation in Git is to stick to that
single work/repo tree, even when that's a shortsighted way of working.
Fossil doesn't work that way. A Fossil repository is an SQLite database
file which is normally stored outside the working checkout directory. You can
[/help?cmd=open | open] a Fossil repository any number of times into
any number of working directories. A common usage pattern is to have one
working directory per active working branch, so that switching branches
is done with a <tt>cd</tt> command rather than by checking out the
branches successively in a single working directory.
Fossil does allow you to switch branches within a working checkout
directory, and this is also often done. It is simply that there is no
inherent penalty to either choice in Fossil as there is in Git. The
standard advice is to use a switch-in-place workflow in Fossil when
the disturbance from switching branches is small, and to use multiple
checkouts when you have long-lived working branches that are different
enough that switching in place is disruptive.
While you can [./gitusers.md#worktree | use Git in the Fossil style],
Git's default tie between working directory and
repository means the standard method for working with a Git repo is to
have one working directory only. Most Git tutorials teach this style, so
it is how most people learn to use Git. Because relatively few people
use Git with multiple working directories per repository, there are
[https://duckduckgo.com/?q=git+worktree+problem | several known
problems] with that way of working, problems which don't happen in Fossil because of
the clear [./ckout-workflows.md | separation] between a Fossil repository and
each working directory.
This distinction matters because switching branches inside a single working directory loses local context
on each switch.
For instance, in any software project where the runnable program must be
built from source files, you invalidate build objects on each switch,
artificially increasing the time required to switch versions. Most obviously, this
affects software written in statically-compiled programming languages
such as C, Java, and Haskell, but it can even affect programs written in
dynamic languages like JavaScript. A typical
[https://en.wikipedia.org/wiki/Single-page_application | SPA] build
process involves several passes: [http://browserify.org/ | Browserify] to convert
[https://nodejs.org/ | Node] packages so they'll run in a web browser,
[https://sass-lang.com | SASS] to CSS translation,
transpilation of [https://www.typescriptlang.org | Typescript] to JavaScript,
[https://github.com/mishoo/UglifyJS | uglification], etc.
Once all that processing work is done for a given input
file in a given working directory, why re-do that work just to switch
versions? If most of the files that differ between versions don't change
very often, you can save substantial time by switching branches with
<tt>cd</tt> rather than swapping versions in-place within a working
checkout directory.
For another example, you might have an active long-running test grinding
away in a working directory, then get a call from a customer requiring
that you switch to a stable branch to answer questions in terms of the
version that customer is running. You don't want to stop the test in
order to switch your lone working directory to the stable branch.
Disk space is cheap. Having several working directories — each with its
own local state — makes switching versions cheap and fast.
Plus,
<tt>cd</tt> is faster to type than <tt>git checkout</tt> or <tt>fossil
update</tt>.

by [https://github.com/olorin37|Jakub A. G.].
<h3 id="history">2.7 What you should have done vs. What you actually did</h3>
Git puts a lot of emphasis on maintaining
a "clean" check-in history. Extraneous and experimental branches by
individual developers often never make it into the main repository.
Branches may be rebased before being pushed to make
it appear as if development had been linear, or "squashed" to make it
appear that multiple commits were made as a single commit.
There are [https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History |
other history rewriting mechanisms in Git] as well. Git strives to record what
the development of a project should have looked like had there been no
mistakes.
Fossil, in contrast, puts more emphasis on recording exactly what happened,
including all of the messy errors, dead-ends, experimental branches, and
so forth. One might argue that this
makes the history of a Fossil project "messy," but another point of view
is that this makes the history "accurate." In actual practice, the
superior reporting tools available in Fossil mean that this incidental mess
is not a factor.
Like Git, Fossil has an [/help?cmd=amend|amend command] for modifying
prior commits, but unlike in Git, this works not by replacing data in
the repository, but by adding a correction record to the repository that
affects how later Fossil operations present the corrected data. The old
information is still there in the repository, it is just overridden from
the amendment point forward.
Fossil lacks almost every other history rewriting mechanism listed on
the Git documentation page linked above. [./rebaseharm.md | There is no
rebase] in Fossil, on purpose, thus no way to reorder or copy commits
around in the commit hash tree. There is no commit squashing, dropping,
or interactive patch-based cherry-picking of commit elements in Fossil.
There is nothing like Git's <tt>filter-branch</tt> in Fossil.
The lone exception is deleting commits. Fossil has two methods for doing
that, both of which have stringent limitations, on purpose.
The first is [/doc/trunk/www/shunning.wiki | shunning]. See that
document for details, but briefly, you only get mandatory compliance
for shun requests within a single repository. Shun requests do not
propagate automatically between repository clones. A Fossil repository
administrator can <i>cooperatively</i> pull another repo's shun requests
across a sync boundary, so that two admins can get together and agree to
shun certain committed artifacts, but a person cannot force their local
shun requests into another repo without having admin-level control over
the receiving repo as well. Fossil's shun feature isn't for fixing up
everyday bad commits, it's for dealing with extreme situations: public
commits of secret material, ticket/wiki/forum spam, law enforcement
takedown demands, etc.
There is also the experimental [/help?cmd=purge | <tt>purge</tt>
command], which differs from shunning in ways that aren't especially
important in the context of this document. At a 30000 foot level, you
can think of purging as useful only when you've turned off Fossil's
autosync feature and want to pluck artifacts out of its hash tree before
they get pushed. In that sense, it's approximately the same as
<tt>git rebase -i, drop</tt>. However, given that Fossil defaults to
having autosync enabled [#devorg | for good reason], the purge command
isn't very useful in practice: once a commit has been pushed into
another repo, shunning is more useful if you need to delete it from
history.
If these accommodations strike you as incoherent with respect to
Fossil's philosophy of durable, unchanging commits, realize that if
shunning and purging were removed from Fossil, you could still remove
artifacts from the repository with SQL <tt>DELETE</tt> statements; the
repository database file is, after all, directly modifiable, being
writable by your user. Where the Fossil philosophy really takes hold is
in making it difficult to violate the integrity of the hash tree.
It's somewhat tangential, but the document [./blockchain.md | "Is Fossil
a Blockchain?"] touches on this and related topics.
One commentator characterized Git as recording history according to
the victors, whereas Fossil records history as it actually happened.
<h3 id="testing">2.8 Test Before Commit</h3>
One of the things that falls out of Git's default separation of commit
from push is that there are several Git sub-commands that jump straight
to the commit step before a change could possibly be tested. Fossil, by
contrast, makes the equivalent change to the local working check-out
only, requiring a separate check-in step to commit the change. This
design difference falls naturally out of Fossil's default-enabled
autosync feature and its philosophy of [#history | not offering history
rewriting features].
The prime example in Git is rebasing: the change happens to the local
repository immediately if successful, even though you haven't tested the
change yet. It's possible to argue for such a design in a tool like Git
since it lacks an autosync feature, because you can still test the
change before pushing local changes to the parent repo, but in the
meantime you've made a durable change to your local Git repository. You
must do something drastic like <tt>git reset --hard</tt> to revert that
rebase or rewrite history before pushing it if the rebase causes a
problem. If you push your rebased local repo up to the parent without
testing first, you cannot fix it without violating
[https://www.atlassian.com/git/tutorials/merging-vs-rebasing#the-golden-rule-of-rebasing
| the golden rule of rebasing].
Lesser examples are the Git <tt>merge</tt>, <tt>cherry-pick</tt>, and
<tt>revert</tt> commands, all of which apply work from one branch onto
another, and all of which commit their change to the local repository
immediately without giving you
an opportunity to test the change first unless you give the
<tt>--no-commit</tt> option. Otherwise, you're back in the same boat:
reset the local repository or rewrite history to fix things, then maybe
retry.
Fossil cannot sensibly work that way because of its default-enabled
autosync feature and its purposeful paucity of commands for modifying
commits, as discussed in [#history | the prior section].
Instead of jumping straight to the commit step, Fossil
applies the proposed merge to the local working directory only,
requiring a separate check-in step before the change is committed to the
repository. This gives you a chance to test the change first,
either manually or by running your software's automatic tests. (Ideally,
both!) Thus, Fossil doesn't need rebase, squashing,
<tt>reset --hard</tt>, or other Git commit mutating mechanisms.
Because Fossil requires an explicit commit for a merge, it has the nice
side benefit that it makes you give an explicit commit <i>message</i>
for each merge, whereas Git writes that commit message itself by default
unless you give the optional <tt>--edit</tt> flag to override it.
We don't look at this difference as a workaround in Fossil for autosync,
but instead as a test-first philosophical difference:
<tt>fossil commit</tt> is a <i>commitment</i>. When every commit is
pushed to the parent repo by default, it encourages a working style in
which every commit is tested first. It encourages thinking before
acting. We believe this is an inherently good thing.
Incidentally, this is a good example of Git's messy command design.
These three commands:
<pre>
$ git merge HASH
$ git cherry-pick HASH
$ git revert HASH
</pre>
...are all the same command in Fossil:
<pre>
$ fossil merge HASH
$ fossil merge --cherrypick HASH
$ fossil merge --backout HASH
</pre>
If you think about it, they're all the same function: apply work done on
one branch to another. All that changes between these commands is how
much work gets applied — just one check-in or a whole branch — and the
merge direction. This is the sort of thing we mean when we point out
that Fossil's command interface is simpler than Git's: there are fewer
concepts to keep track of in your mental model of Fossil's internal
operation.
Fossil's implementation of the feature is also simpler to describe. The
brief online help for <tt>[/help?cmd=merge | fossil merge]</tt> is
currently 41 lines long, to which you want to add the 600 lines of
[./branching.wiki | the branching document]. The equivalent
documentation in Git is the aggregation of the man pages for the above
three commands, which is over 1000 lines, much of it mutually redundant.
(e.g. Git's <tt>--edit</tt> and <tt>--no-commit</tt> options get
described three times, each time differently.) Fossil's
documentation is not only more concise, it gives a nice split of brief
online help and full online documentation.
<h3 id="hash">2.9 Hash Algorithm: SHA-3 vs SHA-2 vs SHA-1</h3>
Fossil started out using 160-bit SHA-1 hashes to identify check-ins,
just as in Git. That changed in early 2017 when news of the
[https://shattered.io/|SHAttered attack] broke, demonstrating that SHA-1
collisions were now practical to create. Two weeks later, the creator of
Fossil delivered a new release allowing a clean migration to
[https://en.wikipedia.org/wiki/SHA-3|256-bit SHA-3] with
[./hashpolicy.wiki|full backwards compatibility] to old SHA-1 based
repositories.
In October 2019, after the last of the major binary
package repos offering Fossil upgraded to Fossil 2.<i>x</i>,
we switched the default hash mode so that
the conversion to SHA-3 is fully automatic.
This not
only solves the SHAttered problem, it should prevent a reoccurrence of
similar problems for the foreseeable future.
Meanwhile, the Git community took until August 2018 to publish
[https://git-scm.com/docs/hash-function-transition/|their first plan]
for solving the same problem by moving to SHA-256, a variant of the
[https://en.wikipedia.org/wiki/SHA-2 | older SHA-2 algorithm]. As of
this writing in February 2020, that plan hasn't been implemented, as far
as this author is aware, but there is now
[https://lwn.net/ml/git/20200113124729.3684846-1-sandals@crustytoothpaste.net/
| a competing SHA-256 based plan] which requires complete repository
conversion from SHA-1 to SHA-256, breaking all public hashes in the
repo. One way to characterize such a massive upheaval in Git terms is a
whole-project rebase, which violates the
[https://www.atlassian.com/git/tutorials/merging-vs-rebasing#the-golden-rule-of-rebasing|Golden Rule of Rebasing].
Regardless of the eventual implementation details, we fully expect Git
to move off SHA-1 eventually and for the changes to take years more to
percolate through the community.
Almost three years after Fossil solved this problem, the
[https://sha-mbles.github.io/ | SHAmbles attack] was published, further
weakening the case for continuing to use SHA-1.
The practical impact of attacks like SHAttered and SHAmbles on the
Git and Fossil Merkle trees isn't clear, but you want to have your repositories
moved over to a stronger hash algorithm before someone figures out how
to make use of the weaknesses in the old one. Fossil has had this covered
for years now, so that the solution is now almost universally deployed.

<h3>Asides and Digressions</h3>
<i><small><ol>
<li><p>[./mirrorlimitations.md|Many
things are lost] in making a Git mirror of a Fossil repo due to
limitations of Git relative to Fossil. GitHub adds some of these
missing features to stock
Git, but because they're not part of Git proper,
[./mirrortogithub.md|exporting a Fossil repository to GitHub] will
still not include them; Fossil tickets do not become GitHub issues,
for example.
<li><p>The <tt>fossil-scm.org</tt> web site is actually hosted in
several parts, so that it is not strictly true that "everything" on
it is in the self-hosting Fossil project repo. The web forum is
hosted as [https://fossil-scm.org/forum/|a separate Fossil repo]
from the [https://fossil-scm.org/home/|main Fossil self-hosting
repo] for administration reasons, and the Download page content
isn't normally synchronized with a "<tt>fossil clone</tt>" command unless
you add the "-u" option. (See "[./aboutdownload.wiki|How the
Download Page Works]" for details.)
Chat history is deliberately not synced as
chat messages are intended to be ephemeral.
There may also be some purely
static elements of the web site served via D. Richard Hipp's own
lightweight web server,
<tt>[https://sqlite.org/althttpd/|althttpd]</tt>,
which is configured as a front end to Fossil running in CGI mode on
these sites.
<li><p>That estimate is based on pricing at Digital Ocean in
mid-2019: Fossil will run just fine on the smallest instance they
offer, at US $5/month, but the closest match to GitLab's minimum
requirements among Digital Ocean's offerings currently costs
$40/month.
<li><p>This means you can give up waiting for Fossil to be ported to
the PDP-11, but we remain hopeful that someone may eventually port
it to [https://en.wikipedia.org/wiki/Z/OS|z/OS].
<li><p>"Why is there all this Tcl in and around Fossil?" you may
ask. It is because D. Richard Hipp is a long-time Tcl user and
contributor. SQLite started out as an embedded database for Tcl
specifically. ([https://sqlite.org/tclsqlite.html | [Reference]])
When he then created Fossil to manage the development of SQLite, it
was natural for him to use Tcl-based tools for its scripting, build
system, test system, etc. It came full circle in 2011 when
[https://www.reddit.com/r/programming/comments/fwrx5/tcl_and_tk_move_away_from_cvs_to_fossil/
| the Tcl and Tk projects moved from CVS to Fossil].
<li><p>A minority of the pieces of the Git core software suite are
written in other languages, primarily Perl, Python, and Tcl. (e.g.
<tt>git-send-mail</tt>, <tt>git-p4</tt>, and <tt>gitk</tt>,
respectively.) Although these interpreters are quite portable, they
aren't installed by default everywhere, and on some platforms you
can't count on them at all. (Not just Windows, but also the BSDs and
many other non-Linux platforms.) This expands the dependency
footprint of Git considerably. It is why the current Git for Windows
distribution is 44.7 MiB but the current <tt>fossil.exe</tt>
zip file for Windows is 2.24 MiB. Fossil is much smaller
despite using a roughly similar amount of high-level scripting code
because its interpreters are compact and built into Fossil itself.
<li><p>Both Fossil and Git support
[https://en.wikipedia.org/wiki/Patch_(Unix)|<tt>patch(1)</tt>
files] — unified diff formatted output — for accepting drive-by contributions, but it's a
lossy contribution path for both systems. Unlike Git PRs and Fossil
bundles, patch files collapse multiple checkins together, they don't
include check-in comments, and they cannot encode changes made above
the individual file content layer: you lose branching decisions,
tag changes, file renames, and more when using patch files. The
[./patchcmd.md | <tt>fossil patch</tt> command]
also solves these problems, but it is because it works like a Fossil
bundle, only for uncommitted changes; it doesn't use Larry Wall's
<tt>patch</tt> tool to apply unified diff output to the receiving
Fossil checkout.</p></li>

The prompt shows the branch, version, and time stamp for the current checkout, and the prompt changes colors from blue to red when there are uncommitted changes. To try out this script, simply download it from the link above, then type: <pre> . fossil_prompt.sh </pre> For a permanent installation, you can graft the code into your <tt>.bashrc</tt> file in your home directory. The code is very simple (only 32 non-comment lines, as of this writing) and hence easy to customize. |

# Git to Fossil Translation Guide
## Introduction
Fossil shares many similarities with Git. In many cases, the
sub-commands are identical: [`fossil bisect`][fbis] does essentially the
same thing as [`git bisect`][gbis], for example.
Yet, Fossil is not merely Git with a bunch of commands misspelled. If
that were the case, we could give you a two-column translation table
which would tell you [how to say things like “`git reset --hard HEAD`â€](#reset) in
this funny ol’ Fossil dialect of Git and be done. The purpose of this
document is to cover all the cases where there is no simple 1:1 mapping,
usually because of intentional design differences in Fossil that prevent
it from working exactly like Git. We choose to explain these differences
since to understand the conversion, you need to know why each difference
exists.
We focus on practical command examples here, leaving discussions of the
philosophical underpinnings that drive these command differences to [another
document][fvg]. The [case studies](#cs1) do get a bit philosophical, but
it is with the aim of illustrating how these Fossil design differences
cause Fossil to behave materially differently from Git in everyday
operation.
We present this from the perspective of Git users moving to Fossil, but
it is also possible to read this document as a Fossil user who speaks
only pidgin Git, who may often have questions of the form, “Now how do I
do X in Git again?â€
This document’s authors are intimately familiar with Fossil, so it is
difficult for us to anticipate the perspective of people who are
intimately familiar with Git. If you have a lot of prior Git
experience, we welcome your contributions and questions on the [Fossil
Forum][ffor].
While we do try to explain Fossil-specific terminology inline here
as-needed, you may find it helpful to skim [the Fossil glossary][gloss].
It will give you another take on our definitions here, and it may help
you to understand some of the other Fossil docs better.

## Repositories and Checkouts Are Distinct
A repository and a check-out are distinct in Fossil, allowing them to be
stored in separate directory trees, whereas the two are commingled by
default with Git, with the repository stored in a `.git` subdirectory
underneath your working directory. This difference shows up in several
separate places when it comes to moving from Git to Fossil.
#### <a id="cwork" name="scw"></a> Checkout Workflows
A Fossil repository is an SQLite database storing the entire history of a
project. It is not normally stored inside the working tree.
A Fossil working tree — [also called a check-out](./glossary.md#check-out) — is a directory
that contains a snapshot of your project that you are currently working
on, extracted for you from the repository database file by the `fossil`
program.
There are ways to
[emulate the Fossil working style in Git](#worktree), but because they’re not
designed into the core concept of the tool, Git tutorials usually
advocate a switch-in-place working mode instead, so that is how most
users end up working with Git. Contrast [Fossil’s check-out workflow
document][ckwf] to see the practical differences.
There is one Git-specific detail we wish to add beyond what that
document already covers. This command:
git checkout some-branch
…is best given as:
fossil update some-branch
…in Fossil. There is a [`fossil checkout`][co] command, but it has
[several differences](./co-vs-up.md) that make it less broadly useful
than [`fossil update`][up] in everyday operation, so we recommend that
Git users moving to Fossil develop a habit of typing `fossil up` rather
than `fossil checkout`. That said, one of those differences does match
up with Git users’ expectations: `fossil checkout` doesn’t pull changes
from the remote repository into the local clone as `fossil update` does.
We think this is less broadly useful, but that’s the subject of the next
section.
[ckwf]: ./ckout-workflows.md
[co]: /help?cmd=checkout
#### <a id="pullup"></a> Update vs Pull
The closest equivalent to [`git pull`][gpull] is not
[`fossil pull`][fpull], but in fact [`fossil up`][up].
This is because
Fossil tends to follow the CVS command design: `cvs up` pulls
changes from the central CVS repository and merges them into the local
working directory, so that’s what `fossil up` does, too. (This design
choice also tends to make Fossil feel comfortable to Subversion
expatriates.)
The `fossil pull` command is simply the reverse of
`fossil push`, so that `fossil sync` [is functionally equivalent
to](./sync.wiki#sync):
fossil push ; fossil pull
There is no implicit “and update the local working directory†step in Fossil’s
push, pull, or sync commands, as there is with `git pull`.
Someone coming from the Git perspective may perceive that `fossil up`
has two purposes:
* Without the optional `VERSION` argument, it updates the working
check-out to the tip of the current branch, as `git pull` does.
* Given a `VERSION` argument, it updates to the named version. If that’s the
name of a branch, it updates to the *tip* of that branch, as
`git checkout BRANCH` does.
In fact, these are the same operation, so they’re the same command in
Fossil. The first form simply allows the `VERSION` to be implicit: the
tip of the current branch.
We think this is a more sensible command design than `git pull` vs
`git checkout`. ([…vs `git checkout` vs `git checkout`!][gcokoan])

#### <a id="close" name="dotfile"></a> Closing a Check-Out
The [`fossil close`][close] command dissociates a check-out directory from the
Fossil repository database, _nondestructively_ inverting [`fossil open`][open].
(Contrast Git’s [closest alternative](#worktree), `git worktree remove`, which *is*
destructive!) This Fossil command does not
remove the managed files, and unless you give the `--force`
option, it won’t let you close the check-out with uncommitted changes to
those managed files.
The `close` command also refuses to run without `--force` when you have
certain other precious per-checkout data that Fossil stores in the
`.fslckout` file at the root of a check-out directory. This is an SQLite
database that keeps track of local state such as what version you have
checked out, the contents of the [stash] for that working directory, the
[undo] buffers, per-checkout [settings][set], and so forth. The stash
and undo buffers are considered precious uncommitted changes,
so you have to force Fossil to discard these as part of closing the
check-out.
Thus, `.fslckout` is not the same thing as `.git`!
In native Windows builds of Fossil — that is, excluding Cygwin and WSL
builds, which follow POSIX conventions — this file is called `_FOSSIL_`
instead to get around the historical 3-character extension limit with
certain legacy filesystems.
Closing a check-out directory is a rare operation. One use case
is that you’re about to delete the directory, so you want Fossil to forget about it
for the purposes of commands like [`fossil all`][all]. Even that isn’t
necessary, because Fossil will detect that this has happened and forget
the working directory for you.
[all]: /help?cmd=all
#### <a id="worktree"></a> Git Worktrees
There are at least three different ways to get [Fossil-style multiple
check-out directories][mcw] with Git.
The old way is to simply symlink the `.git` directory between working
trees:
mkdir ../foo-branch
ln -s ../actual-clone-dir/.git .
git checkout foo-branch
The symlink trick has a number of problems, the largest being that
symlinks weren’t available on Windows until Vista, and until the Windows
10 Creators Update was released in spring of 2017, you had to be an
Administrator to use the feature besides. ([Source][wsyml]) Git 2.5 solved
this problem back when Windows XP was Microsoft’s current offering
by adding the `git-worktree` command:
git worktree add ../foo-branch foo-branch
cd ../foo-branch
That is approximately equivalent to this in Fossil:
mkdir ../foo-branch
cd ../foo-branch
fossil open /path/to/repo.fossil foo-branch
The Fossil alternative is wordier, but since this tends to be one-time setup,
not something you do everyday, the overhead is insignificant. This author keeps a “scratch†check-out
for cases where it’s inappropriate to reuse the “trunk†check-out,
isolating all of my expedient switch-in-place actions to that one
working directory. Since the other peer check-outs track long-lived
branches, and that set rarely changes once a development machine is set
up, I rarely pay the cost of these wordier commands.
That then leads us to the closest equivalent in Git to [closing a Fossil
check-out](#close):
git worktree remove .
Note, however, that unlike `fossil close`, once the Git command
determines that there are no uncommitted changes, it blows away all of
the checked-out files! Fossil’s alternative is shorter, easier to
remember, and safer.
There’s another way to get Fossil-like separate worktrees in Git:
git clone --separate-git-dir repo.git https://example.com/repo
This allows you to have your Git repository directory entirely separate
from your working tree, with `.git` in the check-out directory being a
file that points to `../repo.git`, in this example.

#### <a id="iip"></a> Init in Place
To illustrate the differences that Fossil’s separation of repository
from working directory creates in practice, consider this common Git “init in placeâ€
method for creating a new repository from an existing tree of files,
perhaps because you are placing that project under version control for
the first time:
cd long-established-project
git init
git add *
git commit -m "Initial commit of project."
The closest equivalent in Fossil is:
cd long-established-project
fossil init .fsl
fossil open --force .fsl
fossil add *
fossil ci -m "Initial commit of project."
Note that unlike in Git, you can abbreviate the “`commit`†command in
Fossil as “`ci`†for compatibility with CVS, Subversion, etc.
This creates a `.fsl` repo DB at the root of the project check-out to
emulate the `.git` repo dir. We have to use the `--force` flag on
opening the new repo because Fossil expects you to open a repo into an
empty directory in order to avoid spamming the contents of a repo over
an existing directory full of files. Here, we know the directory
contains files that will soon belong in the repository, though, so we
override this check. From then on, Fossil works like Git, for the
purposes of this example.
We’ve drawn this example to create a tight parallel between Fossil and
Git, not to commend this `.fsl`-at-project-root trick to you. A better
choice would be `~/museum/home/long-established-project.fossil`, if
you’re following [the directory scheme exemplified in the glossary](./glossary.md#repository). That said, it
does emphasize an earlier point: Fossil doesn’t care where you put the
repo DB file or what you name it.

## <a id="log"></a> Fossil’s Timeline Is the “Logâ€
Git users often need to use the `git log` command to dig linearly through
commit histories due to its [weak data model][wdm], giving [O(n)
performance][ocomp].
Fossil parses a huge amount of information out of commits that allow it
to produce its [timeline CLI][tlc] and [its `/timeline` web view][tlw]
using indexed SQL lookups, which generally have the info you would have
to manually extract from `git log`, produced much more quickly than Git
can, all else being equal: operations over [SQLite’s B-tree data structures][btree]
generally run in O(log n) time, faster than O(n) for equal *n* when the
constants are equal.
Yet the constants are *not* equal because Fossil
reads from a single disk file rather than visit potentially many
files in sequence as Git must, so the OS’s buffer cache can result in
[still better performance][35pct].
Unlike Git’s log, Fossil’s timeline shows info across all branches by
default, a feature for maintaining better situational awareness.
It is possible to restrict the timeline to a single branch using `fossil timeline -b`.
Similarly, to restrict the timeline using the web UI equivalent,
click the name of a branch on the `/timeline` or `/brlist` page. (Or
manually, by adding the `r=` query parameter.) Note that even in this
case, the Fossil timeline still shows other branches where they interact
with the one you’ve referenced in this way; again, better situational
awareness.
#### <a id="emu-log"></a> Emulating `git log`
If you truly need a backwards-in-time-only view of history in Fossil to
emulate `git log`, this is as close as you can currently come:
fossil timeline parents current
Again, though, this isn’t restricted to a single branch, as `git log`
is.
Another useful rough equivalent is:
git log --raw
fossil time -v
This shows what changed in each version, though Fossil’s view is more a
summary than a list of raw changes. To dig deeper into single commits,
you can use Fossil’s [`info` command][infoc] or its [`/info` view][infow].
Inversely, you may more exactly emulate the default `fossil timeline`
output with `git log --name-status`.
#### <a id="whatchanged"></a> What Changed?
A related — though deprecated — command is `git whatchanged`, which gives results similar to
`git log --raw`, so we cover it here.
Though there is no `fossil whatchanged` command, the same sort of
information is available. For example, to pull the current changes from
the remote repository and then inspect them before updating the local
working directory, you might say this in Git:
git fetch
git whatchanged ..@{u}
…which you can approximate in Fossil as:
fossil pull
fossil up -n
fossil diff --from tip
To invert the `diff` to show a more natural patch, the command needs to
be a bit more complicated, since you can’t currently give `--to`
without `--from`.
fossil diff --from current --to tip
Rather than use the “dry run†form of [the `update` command][up], you can
say:
fossil timeline after current
…or if you want to restrict the output to the current branch:
fossil timeline descendants current
#### <a id="ckin-names"></a> Symbolic Check-In Names
Note the use of [human-readable symbolic version names][scin] in Fossil
rather than [Git’s cryptic notations][gcn].
For a more dramatic example of this, let us ask Git, “What changed since the
beginning of last month?†being October 2020 as I write this:
git log master@{2020-10-01}..HEAD
That’s rather obscure! Fossil answers the same question with a simpler
command:
fossil timeline after 2020-10-01
You may need to add `-n 0` to bypass the default output limit of
`fossil timeline`, 20 entries. Without that, this command reads
almost like English.
Some Git users like to write commands like the above so:
git log @{2020-10-01}..@
Is that better? “@†now means two different things: an at-time reference
and a shortcut for `HEAD`!
If you are one of those that like short commands, Fossil’s method is
less cryptic: it lets you shorten words in most cases up to the point
that they become ambiguous. For example, you may abbreviate the last
`fossil` command in the prior section:
fossil tim d c
…beyond which the `timeline` command becomes ambiguous with `ticket`.
Some Fossil users employ shell aliases, symlinks, or scripts to shorten
the command still further:
alias f=fossil
f tim d c
Granted, that’s rather obscure, but you you can also choose something
intermediate like “`f time desc curr`â€, which is reasonably clear.

## <a id="dhead"></a> Detached HEAD State
The SQL indexes in Fossil which we brought up above have a useful
side benefit: you cannot have a [detached HEAD state][gdh] in Fossil,
the source of untold pain and data loss in Git. It simply cannot be done
in Fossil, because the indexes always let us find our way back into the
hash tree.
## <a id="slcom"></a> Summary Line Convention in Commit Comments
The Git convention of a [length-limited summary line][lsl] at the start
of commit comments is not enforced or obeyed by default in Fossil.
However, there is a setting under Admin → Timeline → “Truncate comment
at first blank line (Git-style)†to change this for `/timeline`
displays. Alternately, you could enable the “Allow block-markup in
timeline†setting under Admin → Timeline, then apply [local skin
customizations][cskin] to put that first comment in bold or whatever
suits.
Because this isn’t a typical Fossil convention, you’re likely to find
other odd differences between it and Git-based infrastructure. For
instance, Vim doesn’t ship with syntax support for Fossil commit
messages if you set `EDITOR=vim` in your shell environment, so you won’t
get over-limit highlighting for first-line text beyond the 50th
character and such, because it doesn’t recognize Fossil commit messages
and apply similar rules as to Git commit messages.
[cskin]: ./customskin.md
[lsl]: https://chris.beams.io/posts/git-commit/#limit-50
<a id="autocommit"></a>
## Fossil Never Auto-Commits
There are several features in Git besides its `commit` command that
produce a new commit to the repository, and by default, they do it
without prompting or even asking for a commit message. These include
Git’s [`rebase`](#rebase), `merge`, and [`cherrypick`](#cpickrev)
commands, plus the [commit splitting](#comsplit) sub-feature
“`git commit -p`â€.
Fossil never does this, on firm philosophical grounds: we wish to be
able to test that each potentially repository-changing command does not
break anything _before_ freezing it immutably into the [Merkle
tree](./blockchain.md). Where Fossil has equivalent commands, they
modify the checkout tree alone, requiring a separate `commit` command
afterward, withheld until the user has satisfied themselves that the
command’s result is correct.
We believe this is the main reason Git lacks an [autosync](#autosync)
feature: making push a manual step gives the user a chance to rewrite
history after triggering one of these autocommits locally, should the
automatic commit fail to work out as expected. Fossil chooses the
inverse path under the philosophy that commits are *commitments,* not
something you’re allowed to go back and rewrite later.
This is also why there is no automatic commit message writing feature in
Fossil, as in these autocommit-triggering Git commands. The user is
meant to write the commit message by hand after they are sure it’s
correct, in clear-headed retrospective fashion. Having the tool do it
prospectively before one can test the result is simply backwards.
<a id="staging"></a>
## There Is No Staging Area
Fossil omits the "Git index" or "staging area" concept. When you
type "`fossil commit`" _all_ changes in your check-out are committed,
by default. There is no need for the "-a" option as with Git.
If you only want to commit _some_ of the changes, list the names
of the files or directories you want to commit as arguments, like this:
fossil commit src/feature.c doc/feature.md examples/feature
Note that the last element is a directory name, meaning “any changed
file under the `examples/feature` directory.â€
<a id="comsplit"></a>
## Commit Splitting
[Git’s commit splitting features][gcspl] rely on
other features of Git that Fossil purposefully lacks, as covered in the
prior two sections: [autocommit](#autocommit) and [the staging
area](#staging).
While there is no direct Fossil equivalent for
`git add -p`, `git commit -p`, or `git rebase -i`, you can get the same
effect by converting an uncommitted change set to a patch and then
running it through [Patchouli].
Rather than use `fossil diff -i` to produce such a patch, a safer and
more idiomatic method would be:
fossil stash save -m 'my big ball-o-hackage'
fossil stash diff > my-changes.patch
That stores your changes in the stash, then lets you operate on a copy
of that patch. Each time you re-run the second command, it will take the
current state of the working directory into account to produce a
potentially different patch, likely smaller because it leaves out patch
hunks already applied.
In this way, the combination of working tree and stash replaces the need
for Git’s index feature.
We believe we know how to do commit splitting in a way compatible with
the Fossil philosophy, without following Git’s ill-considered design
leads. It amounts to automating the above process through an interactive
variant of [`fossil stash apply`][stash], as currently prototyped in the
third-party tool [`fnc`][fnc] and [its interactive `stash`
command][fncsta]. We merely await someone’s [contribution][ctrb] of this
feature into Fossil proper.

<a id="bneed"></a>
## Create Branches at Point of Need, Rather Than Ahead of Need
Fossil prefers that you create new branches as part of the first commit
on that branch:
fossil commit --branch my-branch
If that commit is successful, your local check-out directory is then
switched to the tip of that branch, so subsequent commits don’t need the
“`--branch`†option. You simply say `fossil commit` again to continue
adding commits to the tip of that branch.
To switch back to the parent branch, say something like:
fossil update trunk
(This is approximately equivalent to `git checkout master`.)
Fossil does also support the Git style, creating the branch ahead of
need:
fossil branch new my-branch
fossil up my-branch
...work on first commit...
fossil commit
This is more verbose, giving the same overall effect though the initial
actions are inverted: create a new branch for the first commit, switch
the check-out directory to that branch, and make that first commit. As
above, subsequent commits are descendants of that initial branch commit.
We think you’ll agree that creating a branch as part of the initial
commit is simpler.
Fossil also allows you to move a check-in to a different branch
*after* you commit it, using the "`fossil amend`" command.
For example:
fossil amend current --branch my-branch
This works by inserting a tag into the repository that causes the web UI
to relabel commits from that point forward with the new name. Like Git,
Fossil’s fundamental data structure is the interlinked DAG of commit
hashes; branch names are supplemental data for making it easier for the
humans to understand this DAG, so this command does not change the core
history of the project, only annotate it for better display to the
humans.
(The version string “current†is one of the [special check-in names][scin] in Fossil. See
that document for the many other names you can give to “`amend`â€, or
indeed to any other Fossil command documented to accept a `VERSION` or
`NAME` string.)
[scin]: ./checkin_names.wiki
<a id="syncall"></a>
## Sync Is All-or-Nothing
Fossil does not support the concept of syncing, pushing, or pulling
individual branches. When you sync/push/pull in Fossil, it
processes all artifacts in its hash tree:
branches, tags, wiki articles, tickets, forum posts, technotes…
This is [not quite “everything,†full stop][bu], but it’s close.
[Fossil is an AP-mode system][capt], which in this case means it works
*very hard* to ensure that all repos are as close to identical as it can
make them under this eventually-consistent design philosophy.
Branch *names* sync automatically in Fossil, not just the
content of those branches. That means this common Git command:
git push origin master
…is simply this in Fossil:
fossil push
Fossil doesn’t need to be told what to push or where to push it: it just
keeps using the same remote server URL you gave it last
until you [tell it to do something different][rem]. It pushes all
branches, not just one named local branch.
[capt]: ./cap-theorem.md
[rem]: /help?cmd=remote
<a id="autosync"></a>
## Autosync
Fossil’s [autosync][wflow] feature, normally enabled, has no
equivalent in Git. If you want Fossil to behave like Git, you can turn
it off:
fossil set autosync 0
Let’s say that you have a typical server-and-workstations model with two
working clones on different machines, that you have disabled autosync,
and that this common sequence then occurs:
1. Alice commits to her local clone and *separately* pushes the change
up to Condor — their central server — in typical Git fashion.
2. Bob does the same.
3. Alice brings Bob’s changes down from Condor with “`fossil pull`,†sees
what he did to their shared working branch, and becomes most wrathful.
(Tsk, tsk.)
We’ll get to what you do about this situation [below](#reset), but for
now let us focus on the fact that disabling autosync makes it easier for
[forks] to occur in the development history. If all three machines had
been online and syncing at the time the sequence above began, Bob would
have been warned in step 2 that committing to the central repo would
create a fork and would be invited to fix it before committing.
Likewise, it would allow Fossil to warn Alice about the new
tip-of-branch commit the next time she triggers an implicit autosync at
step 3, giving her a chance to bring Bob’s changes down in a
non-conflicting manner, allowing work to proceed with minimal fuss.
Fossil, being a distributed version control system, cannot guarantee
that sequence of events. Because it allows Alice’s work to proceed
asynchronously, it gives her the chance to create *another* inadvertent
fork before she can trigger an autosync. This is not a serious problem;
Fossil resolves it the same way as with Bob, by inviting her to fix this
second fork in the same manner as it did with Bob. It gets both parties
back onto a single track as expeditiously as possible by moving the
synchronization point out of the expensive human-time workflow and into
the software system, where it’s cheapest to resolve.
Autosync provides Fossil with most of the advantages of a centralized
version control system while retaining the advantages of distributed
version control:
1. Your work stays synced up with your coworkers’ efforts as long as your
machine can connect to the remote repository. At need, you can go
off-network and continue work atop the last version you synced with
the remote.
2. You get implicit off-machine backup of your commits. Unlike
centralized version control, though, you can still work while
disconnected; your changes will sync up with the remote once you get
back online.
3. Because there is [little distinction][bu] between the clones in the Fossil
model — unlike in Git, where clones often quickly diverge from each
other, quite possibly on purpose — the backup advantage applies in inverse
as well: if the remote server falls over dead, one of those with a
clone of that repository can stand it back up, and everyone can get
back to work simply by re-pointing their local repo at the new
remote. If the failed remote comes back later, it can sync with the
new central version, then perhaps take over as the primary source of
truth once again.

<a id="reset"></a>
## Resetting the Repository
Extending from [the prior item](#syncall), you may correctly infer that
“[delete the project and download a fresh copy][x1597]†has no part in
the Fossil Way. Ideally, you should never find yourself forced into
desperate measures like this:(^Parsing the output of `fossil status` is
usually a mistake since it relies on a potentially unstable interface.
We make no guarantee that there will always be a line beginning with
“`repo`†and that it will be separated from the repository’s file name
by a colon. The simplified example above is also liable to become
confused by whitespace in file names.)
```
$ repo=$(fossil status | grep ^repo | cut -f2 -d:)
$ url=$(fossil remote)
$ fossil close # Stop here and think if it warns you!
$ mv $repo ${repo}.old
$ fossil clone $url $repo
$ fossil open --force $repo
```
What, then, should you as a Git transplant do instead when you find
yourself reaching for “`git reset`�
Since the correct answer to that depends on why you think it’s a good
solution to your immediate problem, we’ll take our motivating scenario
from the problem setup above, where we discussed Fossil’s [autosync]
feature. Let us further say Alice’s pique results from a belief that
Bob’s commit is objectively wrong-headed and should be expunged
henceforth. Since Fossil goes out of its way to ensure that [commits are
durable][wdm], it should be no further surprise that there is no easier
method to reset Bob’s clone in favor of Alice’s than the above sequence
in Fossil’s command set. Except in extreme situations, we believe that
sort of thing is unnecessary.
Instead, Bob can say something like this:
```
fossil amend --branch MISTAKE --hide --close -m "mea culpa" tip
fossil up trunk
fossil push
```
Unlike in Git, the “`amend`†command doesn’t modify prior committed
artifacts. Bob’s first command doesn’t delete anything, merely tells
Fossil to hide his mistake from timeline views by inserting a few new
records into the local repository to change how the client interprets
the data it finds there henceforth.(^One to change the tag marking this
commit’s branch name to “`MISTAKE`,†one to mark that branch as hidden,
and one to close it to further commits.)
Bob’s second command switches his working directory back to the prior
commit on that branch. We’re presuming it was “`trunk`†for the sake of
the example, but it works for any parent branch name. The command works
because the name “`trunk`†now means something different to Fossil by
virtue of the first command.
Bob’s third command pushes the changes up to the central machine to
inform everyone else of his amendment.(^Amendments don’t autosync in
Fossil because they don’t change any previous commits, allowing the
other clones to continue working safely with their existing commit
hashes.)
In this scheme, Alice then needs to say “`fossil update trunk`†in order
to return her check-out’s parent commit to the previous version lest her
next attempted commit land atop this mistake branch. The fact that Bob
marked the branch as closed will prevent that from going through, cluing
Alice into what she needs to do to remedy the situation, but that merely
shows why it’s a better workflow if Alice makes the amendment herself:
```
fossil amend --branch MISTAKE --hide --close \
-m "shunt Bob’s erroneous commit off" tip
fossil up trunk
fossil push
```
Then she can fire off an email listing Bob’s assorted failings and go
about her work. This asynchronous workflow solves the problem without
requiring explicit coordination with Bob. When he gets his email, he can
then say “`fossil up trunk`†himself, which by default will trigger an
autosync, pulling down Alice’s amendments and getting him back onto her
development track.
Remember that [branch names need not be unique](#btnames) in Fossil. You
are free to reuse this “`MISTAKE`†branch name as often as you need to.

<a id="trunk"></a>
## The Main Branch Is Called "`trunk`"
In Fossil, the default name for the main branch
is "`trunk`". The "`trunk`" branch in Fossil corresponds to the
"`master`" branch in stock Git or to [the “`main`†branch in GitHub][mbgh].
Because the `fossil git export` command has to work with both stock Git
and with GitHub, Fossil uses Git’s traditional default rather than
GitHub’s new default: your Fossil repo’s “trunk†branch becomes “masterâ€
when [mirroring to GitHub][mirgh] unless you give the `--mainbranch`
option.
We do not know what happens on subsequent exports if you later rename
this branch on the GitHub side.

[mirgh]: ./mirrortogithub.md
<a id="unmanaged"></a>
## Status Does Not Show Unmanaged Files
The "`fossil status`" command shows you what files in your check-out have
been edited and scheduled for adding or removing at the next commit.
But unlike "`git status`", the "`fossil status`" command does not warn
you about unmanaged files in your local check-out. There is a separate
"`fossil extras`" command for that.
<a id="rebase"></a>
## There Is No Rebase
Fossil does not support rebase, [on purpose][3].
This is a deliberate design decision that the Fossil community has
thought about carefully and discussed many times, resulting in the
linked document. If you are fond of rebase, you should read it carefully
before expressing your views: it not only answers many of the common
arguments in favor of rebase known at the time the document’s first
draft was written, it’s been revised multiple times to address less
common objections as well. Chances are not good that you are going to
come up with a new objection that we haven’t already considered and
addressed there.
There is only one sub-feature of `git rebase` that is philosophically
compatible with Fossil yet which currently has no functional equivalent.
We [covered this and the workaround for its lack](#comsplit) above.
[3]: ./rebaseharm.md
<a id="cdiff"></a>
## Colorized Diffs
When you run `git diff` on an ANSI X3.64 capable terminal, it uses color
to distinguish insertions, deletions, and replacements, but as of this
writing, `fossil diff` produces traditional uncolored [unified diff
format][udiff] output, suitable for producing a [patch file][pfile].
There are [many methods](./colordiff.md) for solving this.
Viewed this way, Fossil doesn’t lack colorized diffs, it simply has
*one* method where they *aren’t* colorized.
[pfile]: https://en.wikipedia.org/wiki/Patch_(Unix)
[udiff]: https://en.wikipedia.org/wiki/Diff#Unified_format
## <a id="show"></a> Showing Information About Commits
While there is no direct equivalent to Git’s “`show`†command, similar
functionality is present in Fossil under other commands:
#### <a id="patch"></a> Show a Patch for a Commit
git show -p COMMIT_ID
…gives much the same output as
fossil diff --checkin COMMIT_ID
…only without the patch email header. Git comes out of the [LKML] world,
where emailing a patch is a normal thing to do. Fossil is [designed for
cohesive teams][devorg] where drive-by patches are rarer.
You can use any of [Fossil’s special check-in names][scin] in place of
the `COMMIT_ID` in this and later examples. Fossil docs usually say
“`VERSION`†or “`NAME`†where this is allowed, since the version string
or name might not refer to a commit ID, but instead to a forum post, a
wiki document, etc. For instance, the following command answers the question “What did
I just commit?â€
fossil diff --checkin tip
…or equivalently using a different symbolic commit name:
fossil diff --from prev
[devorg]: ./fossil-v-git.wiki#devorg
[LKML]: https://lkml.org/
#### <a id="cmsg"></a> Show a Specific Commit Message
git show -s COMMIT_ID
…is
fossil time -n 1 COMMIT_ID
…or with a shorter, more obvious command, though with more verbose output:
fossil info COMMIT_ID
The `fossil info` command isn’t otherwise a good equivalent to
`git show`; it just overlaps its functionality in some areas. Much of
what’s missing is present in the corresponding [`/info` web
view][infow], though.
#### <a id="dstat"></a> Diff Statistics
Fossil’s closest internal equivalent to commands like
`git show --stat` is:
fossil diff -i --from 2020-04-01 --numstat
The `--numstat` output is a bit cryptic, so we recommend delegating
this task to [the widely-available `diffstat` tool][dst], which gives
a histogram in its default output mode rather than bare integers:
fossil diff -i -v --from 2020-04-01 | diffstat
We gave the `-i` flag in both cases to force Fossil to use its internal
diff implementation, bypassing [your local `diff-command` setting][dcset]
since the `--numstat` option has no effect when you have an external diff
command set.
If you leave off the `-v` flag in the second example, the `diffstat`
output won’t include info about any newly-added files.

[dst]: https://invisible-island.net/diffstat/diffstat.html
<a id="btnames"></a>
## Branch and Tag Names
Fossil has no special restrictions on the names of tags and branches,
though you might want to keep [Git's tag and branch name restrictions][gcrf]
in mind if you plan on [mirroring your Fossil repository to GitHub][mirgh].
Fossil does not require tag and branch names to be unique. It is
common, for example, to put a “`release`†tag on every release for a
Fossil-hosted project. This does not create a conflict in Fossil, since
Fossil resolves the ambiguity in a predictable way: the newest match
wins. Therefore, “`fossil up release`†always gets you the current
release in a project that uses this tagging convention.
[The `fossil git export` command][fge] squashes repeated tags down to a
single instance to avoid confusing Git, exporting only the newest tag,
emulating Fossil’s own ambiguity resolution rule as best it can within
Git’s limitations.
[fge]: /help?cmd=git
[gcrf]: https://git-scm.com/docs/git-check-ref-format
<a id="cpickrev"></a>
## Cherry-Picking and Reverting Commits
Git’s separate "`git cherry-pick`" and “`git revert`†commands are
options to the [`fossil merge` command][merge]: `--cherrypick` and
`--backout`, respectively. We view this as sensible, since these are
both merge operations, and the two actions differ only in direction.
Unlike in Git, the Fossil file format remembers cherrypicks and backouts
and can later show them as dashed lines on the graphical timeline.
[merge]: /help?cmd=merge
<a id="mvrm"></a>
## File Moves and Renames Are Soft by Default
The "[`fossil mv`][mv]" and "[`fossil rm`][rm]" commands work like they
do in CVS in that they schedule the changes for the next commit by
default: they do not actually rename or delete the files in your
check-out.
If you don’t like that default, you can change it globally:
fossil setting --global mv-rm-files 1
Now these commands behave like in Git in any Fossil repository where
this setting hasn’t been overridden locally.
If you want to keep Fossil’s soft `mv/rm` behavior most of the time, you
can cast it away on a per-command basis:
fossil mv --hard old-name new-name
[mv]: /help?cmd=mv
[rm]: /help?cmd=rm
----
## <a id="cvdate" name="cs1"></a> Case Study 1: Checking Out a Version by Date
Let’s get into something a bit more complicated: a case study showing
how the concepts lined out above cause Fossil to materially differ in
day-to-day operation from Git.
Why would you want to check out a version of a project by date? Perhaps
your customer gave you a vague bug report referencing only a
date rather than a version. Or, you may be poking semi-randomly through
history to find a “good†version to anchor the start point of a
[`fossil bisect`][fbis] operation.
My search engine’s first result for “git checkout by date†is [this
highly-upvoted accepted Stack Overflow answer][gcod]. The first command
it gives is based on Git’s [`rev-parse` feature][grp]:
git checkout master@{2020-03-17}
There are a number of weaknesses in this command. From least to most
critical:
1. It’s a bit cryptic. Leave off the refname or punctuation, and it
means something else. You cannot simplify the cryptic incantation in
the typical use case.
2. A date string in Git without a time will be interpreted as
“[at the local wall clock time on the given date][gapxd],†so the
command means something different from one second to the next! This
can be a serious problem if there are multiple commits on that date, because
the command will give different results depending on the time of
day you run it.
3. It gives misleading output if there is no close match for the date
in the local [reflog]. It starts out empty after a fresh clone, and
while it does build up as you use that clone, Git [automatically
prunes][gle] the reflog to 90 days of history by default. This means
the command above can give different results from one machine to the
next, or even from one day to the next on the same clone.
The command won’t fail outright if the reflog can’t resolve the
given date: it simply gives the closest commit it can come up with,
even if it’s months or years out from your target! Sometimes it
gives a warning about the reflog not going back far enough to give a
useful result, and sometimes it doesn’t. If you’re on a fresh clone,
you are likely to get the “tip†commit’s revision ID no matter what
date value you give.
Git tries its best, but because it’s working from a purgeable and
possibly-stale local cache, you cannot trust its results.
Consequently, we cannot recommend this command at all. It’s unreliable even in the
best case.
That same Stack Overflow answer therefore goes on to recommend an
entirely different command:
git checkout $(git rev-list -n 1 --first-parent --before="2020-03-17" master)
We believe you get such answers to Git help requests in part
because of its lack of an always-up-to-date [index into its log](#log) and in
part because of its “small tools loosely joined†design philosophy. This
sort of command is therefore composed piece by piece:
<p style="text-align:center">◆ ◆ ◆</p>
“Oh, I know, I’ll search the rev-list, which outputs commit IDs by
parsing the log backwards from `HEAD`! Easy!â€
git rev-list --before=2020-03-17
“Blast! Forgot the commit ID!â€
git rev-list --before=2020-03-17 master
“Double blast! It just spammed my terminal with revision IDs! I need to
limit it to the single closest match:
git rev-list -n 1 --before=2020-03-17 master
“Okay, it gives me a single revision ID now, but is it what I’m after?
Let’s take a look…â€
git show $(git rev-list -n 1 --before=2020-03-17 master)
“Oops, that’s giving me a merge commit, not what I want.
Off to search the web… Okay, it says I need to give either the
`--first-parent` or `--no-merges` flag to show only regular commits,
not merge-commits. Let’s try the first one:â€
git show $(git rev-list -n 1 --first-parent --before=2020-03-17 master)
“Better. Let’s check it out:â€
git checkout $(git rev-list -n 1 --first-parent --before=2020-03-17 master)
“Success, I guess?â€
<p style="text-align:center">◆ ◆ ◆</p>
This vignette is meant to explain some of Git’s popularity: it rewards
the sort of people who enjoy puzzles, many of whom are software
developers and thus need a tool like Git. Too bad if you’re just a
normal user.
And too bad if you’re a Windows user who doesn’t want to use [Git
Bash][gbash], since neither of the stock OS command shells have a
command interpolation feature needed to run that horrid command.
This alternative command still has weakness #2 above: if you run the
second `git show` command above on [Git’s own repository][gitgh], your
results may vary because there were four non-merge commits to Git on the
17th of March, 2020.
You may be asking with an exasperated huff, “What is your *point*, man?â€
The point is that the equivalent in Fossil is simply:
fossil up 2020-03-17
…which will *always* give the commit closest to midnight UTC on the 17th
of March, 2020, no matter whether you do it on a fresh clone or a stale
one. The answer won’t shift about from one clone to the next or from
one local time of day to the next. We owe this reliability and stability
to three Fossil design choices:
* Parse timestamps from all commits on clone into a local commit index,
then maintain that index through subsequent commits and syncs.
* Use an indexed SQL `ORDER BY` query to match timestamps to commit
IDs for a fast and consistent result.

## <a id="morigin" name="cs2"></a> Case Study 2: Multiple "origin" Servers
Now let us consider a common use case at the time of this writing — during the
COVID-19 pandemic — where you’re working from home a lot, going into the
office one part-day a week only to do things that have to be done
on-site at the office. Let us also say you have no remote
access back into the work LAN, such as because your site IT is paranoid
about security. You may still want off-machine backups of your commits
while working from home,
so you need the ability to quickly switch between the “home†and
“work†remote repositories, with your laptop acting as a kind of
[sneakernet][sn] link between the big development server at the office
and your family’s home NAS.
#### Git Method
We first need to clone the work repo down to our laptop, so we can work on it
at home:
git clone https://dev-server.example.com/repo
cd repo
git remote rename origin work
The last command is optional, strictly speaking. We could continue to
use Git’s default name for the work repo’s origin — sensibly enough
called “`origin`†— but it makes later commands harder to understand, so
we rename it here. This will also make the parallel with Fossil easier
to draw.
The first time we go home after this, we have to reverse-clone the work
repo up to the NAS:
ssh my-nas.local 'git init --bare /SHARES/dayjob/repo.git'
git push --all ssh://my-nas.local//SHARES/dayjob/repo.git
Realize that this is carefully optimized down to these two long
commands. In practice, we’d expect a user typing these commands by hand from memory
to need to give four or more commands here instead.
Packing the “`git init`†call into the “`ssh`†call is something more
often done in scripts and documentation examples than done interactively,
which then necessitates a third command before the push, “`exit`â€.
There’s also a good chance that you’ll forget the need for the `--bare`
option here to avoid a fatal complaint from Git that the laptop can’t
push into a non-empty repo. If you fall into this trap, among the many
that Git lays for newbies, you have to nuke the incorrectly initted
repo, search the web or Git man pages to find out about `--bare`, and try again.
Having navigated that little minefield,
we can tell Git that there is a second origin, a “home†repo in
addition to the named “work†repo we set up earlier:
git remote add home ssh://my-nas.local//SHARES/dayjob/repo.git
git config master.remote home
We don’t have to push or pull because the remote repo is a complete
clone of the repo on the laptop at this point, so we can just get to
work now, committing along the way to get our work safely off-machine
and onto our home NAS, like so:
git add
git commit
git push
We didn’t need to give a remote name on the push because we told it the
new upstream is the home NAS earlier.
Now Friday comes along, and one of your office-mates needs a feature
you’re working on. You agree to come into the office later that
afternoon to sync up via the dev server:
git push work master # send your changes from home up
git pull work master # get your coworkers’ changes
Alternately, we could add “`--set-upstream/-u work`†to the first
command if we were coming into work long enough to do several Git-based things, not just pop in and sync.
That would allow the second to be just “`git pull`â€, but the cost is
that when returning home, you’d have to manually reset the upstream
again.
This example also shows a consequence of that fact that
[Git doesn’t sync branch names](#syncall): you have to keep repeating
yourself like an obsequious supplicant: “Master, master.†Didn’t we
invent computers to serve humans, rather than the other way around?
#### Fossil Method
Now we’re going to do the same thing using Fossil, with
the commands arranged in blocks corresponding to those above for comparison.
We start the same way, cloning the work repo down to the laptop:
fossil clone https://dev-server.example.com/repo
cd repo
fossil remote add work https://dev-server.example.com/repo
We’ve chosen the new “`fossil clone URI`†syntax rather than separate
`clone` and `open` commands to make the parallel with Git clearer. [See
above](#mwd) for more on that topic.
Our [`remote` command][rem] is longer than the Git equivalent because
Fossil currently has no short command
to rename an existing remote. Worse, unlike with Git, we can’t just keep
using the default remote name because Fossil uses that slot in its
configuration database to store the *current* remote name, so on
switching from work to home, the home URL will overwrite the work URL if
we don’t give it an explicit name first.
Although the Fossil commands are longer, so far, keep it in perspective:
they’re one-time setup costs,
easily amortized to insignificance by the shorter day-to-day commands
below.
On first beginning to work from home, we reverse-clone the Fossil repo
up to the NAS:
rsync repo.fossil my-nas.local:/SHARES/dayjob/
Now we’re beginning to see the advantage of Fossil’s simpler model,
relative to the tricky “`git init && git push`†sequence above.
Fossil’s alternative is almost impossible to get
wrong: copy this to that. *Done.*
We’re relying on the `rsync` feature that creates up to one level of
missing directory (here, `dayjob/`) on the remote. If you know in
advance that the remote directory already exists, you could use a
slightly shorter `scp` command instead. Even with the extra 2 characters
in the `rsync` form, it’s much shorter because a Fossil repository is a
single SQLite database file, not a tree containing a pile of assorted
files. Because of this, it works reliably without any of [the caveats
inherent in using `rsync` to clone a Git repo][grsync].
Now we set up the second remote, which is again simpler in the Fossil
case:
fossil remote add home ssh://my-nas.local//SHARES/dayjob/repo.fossil
fossil remote home
The first command is nearly identical to the Git version, but the second
is considerably simpler. And to be fair, you won’t find the
“`git config`†command above in all Git tutorials. The more common
alternative we found with web searches is even longer:
“`git push --set-upstream home master`â€.
Where Fossil really wins is in the next step, making the initial commit
from home:
fossil ci
It’s one short command for Fossil instead of three for Git — or two if
you abbreviate it as “`git commit -a && git push`†— because of Fossil’s
[autosync] feature and deliberate omission of a
[staging feature](#staging).
The “Friday afternoon sync-up†case is simpler, too:
fossil remote work
fossil sync
Back at home, it’s simpler still: we may be able to do away with the second command,
saying just “`fossil remote home`†because the sync will happen as part
of the next commit, thanks once again to Fossil’s autosync feature. If
the working branch now has commits from other developers after syncing
with the central repository, though, you’ll want to say “`fossil up`†to
avoid creating an inadvertent fork in the branch.
(Which is easy to fix if it occurs: `fossil merge` without arguments
means “merge open tips on the current branch.â€)

# File Name Glob Patterns
A [glob pattern][glob] is a text expression that matches one or more
file names using wildcards familiar to most users of a command line.
For example, `*` is a glob that matches any name at all, and
`Readme.txt` is a glob that matches exactly one file. For purposes of
Fossil's globs, a complete path name is just a string,
and the globs do not apply any special meaning to the directory part
of the name. Thus, the glob `*` matches any name, including any
directory prefix, and `*/*` matches a name with _one or more_
directory components.
A glob should not be confused with a [regular expression][regexp] (RE)
even though they use some of the same special characters for similar
purposes. [They are not fully compatible][greinc] pattern
matching languages. Fossil uses globs when matching file names with the
settings described in this document, not REs.
[glob]: https://en.wikipedia.org/wiki/Glob_(programming)
[greinc]: https://unix.stackexchange.com/a/57958/138
[regexp]: https://en.wikipedia.org/wiki/Regular_expression
[Fossil’s `*-glob` settings](#settings) hold one or more patterns to cause Fossil to
give matching named files special treatment. Glob patterns are also
accepted in options to certain commands and as query parameters to
certain Fossil UI web pages. For consistency, settings such as
`empty-dirs` are parsed as a glob even though they aren’t then *applied*
as a glob since it allows [the same syntax rules](#syntax) to apply.
Where Fossil also accepts globs in commands, this handling may interact
with your OS’s command shell or its C runtime system, because they may
have their own glob pattern handling. We will detail such interactions
below.
## <a id="syntax"></a>Syntax
Where Fossil accepts glob patterns, it will usually accept a *list* of
individual patterns separated from the others by whitespace or commas.
The parser allows whitespace and commas in a pattern by quoting _the
entire pattern_ with either single or double quotation marks. Internal
quotation marks are treated literally. Moreover, a pattern that begins
with a quote mark ends when the first instance of the same mark occurs,
_not_ at a whitespace or comma. Thus, this:
"foo bar"qux
…constitutes _two_ patterns rather than one with an embedded space, in
contravention of normal shell quoting rules.
A list matches a file when any pattern in that list matches.
A pattern must consume and
match the *entire* file name to succeed. Partial matches are failed matches.
Most characters in a glob pattern consume a single character of the file
name and must match it exactly. For instance, “a†in a glob simply
matches the letter “a†in the file name unless it is inside a special
character sequence.
Other characters have special meaning, and they may include otherwise
normal characters to give them special meaning:
:Pattern |:Effect
---------------------------------------------------------------------
`*` | Matches any sequence of zero or more characters
`?` | Matches exactly one character
`[...]` | Matches one character from the enclosed list of characters
`[^...]` | Matches one character *not* in the enclosed list
Note that unlike [POSIX globs][pg], these special characters and
sequences are allowed to match `/` directory separators as well as the
initial `.` in the name of a hidden file or directory. This is because
Fossil file names are stored as complete path names. The distinction
between file name and directory name is “underneath†Fossil in this sense.
[pg]: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13
The bracket expressions above require some additional explanation:
* A range of characters may be specified with `-`, so `[a-f]` matches
exactly the same characters as `[abcdef]`. Ranges reflect Unicode
code points without any locale-specific collation sequence.
Therefore, this particular sequence never matches the Unicode
pre-composed character `é`, for example. (U+00E9)
* This dependence on character/code point ordering may have other
effects to surprise you. For example, the glob `[A-z]` not only
matches upper and lowercase ASCII letters, it also matches several
punctuation characters placed between `Z` and `a` in both ASCII and
Unicode: `[`, `\`, `]`, `^`, `_`, and <tt>\`</tt>.
* You may include a literal `-` in a list by placing it last, just
before the `]`.
* You may include a literal `]` in a list by making the first
character after the `[` or `[^`. At any other place, `]` ends the list.
* You may include a literal `^` in a list by placing it anywhere
except after the opening `[`.
* Beware that a range must be specified from low value to high
value: `[z-a]` does not match any character at all, preventing the
entire glob from matching.
Some examples of character lists:
:Pattern |:Effect
---------------------------------------------------------------------
`[a-d]` | Matches any one of `a`, `b`, `c`, or `d` but not `ä`
`[^a-d]` | Matches exactly one character other than `a`, `b`, `c`, or `d`
`[0-9a-fA-F]` | Matches exactly one hexadecimal digit
`[a-]` | Matches either `a` or `-`
`[][]` | Matches either `]` or `[`
`[^]]` | Matches exactly one character other than `]`
`[]^]` | Matches either `]` or `^`
`[^-]` | Matches exactly one character other than `-`
White space means the specific ASCII characters TAB, LF, VT, FF, CR,
and SPACE. Note that this does not include any of the many additional
spacing characters available in Unicode such as
U+00A0, NO-BREAK SPACE.
Because both LF and CR are white space and leading and trailing spaces
are stripped from each glob in a list, a list of globs may be broken
into lines between globs when the list is stored in a file, as for a
versioned setting.
Note that 'single quotes' and "double quotes" are the ASCII straight
quote characters, not any of the other quotation marks provided in
Unicode and specifically not the "curly" quotes preferred by
typesetters and word processors.
## File Names to Match
Before it is compared to a glob pattern, each file name is transformed
to a canonical form:
* all directory separators are changed to `/`
* redundant slashes are removed
* all `.` path components are removed
* all `..` path components are resolved
(There are additional details we are ignoring here, but they cover rare
edge cases and follow the principle of least surprise.)
The glob must match the *entire* canonical file name to be considered a
match.
The goal is to have a name that is the simplest possible for each
particular file, and that will be the same regardless of the platform
you run Fossil on. This is important when you have a repository cloned
from multiple platforms and have globs in versioned settings: you want
those settings to be interpreted the same way everywhere.
Beware, however, that all glob matching in Fossil is case sensitive
regardless of host platform and file system. This will not be a surprise
on POSIX platforms where file names are usually treated case
sensitively. However, most Windows file systems are case preserving but
case insensitive. That is, on Windows, the names `ReadMe` and `README`
are usually names of the same file. The same is true in other cases,
such as by default on macOS file systems and in the file system drivers
for Windows file systems running on non-Windows systems. (e.g. exfat on
Linux.) Therefore, write your Fossil glob patterns to match the name of
the file as checked into the repository.
Some example cases:
:Pattern |:Effect
--------------------------------------------------------------------------------
`README` | Matches only a file named `README` in the root of the tree. It does not match a file named `src/README` because it does not include any characters that consume (and match) the `src/` part.
`*/README` | Matches `src/README`. Unlike Unix file globs, it also matches `src/library/README`. However it does not match the file `README` in the root of the tree.
`*README` | Matches `src/README` as well as the file `README` in the root of the tree as well as `foo/bar/README` or any other file named `README` in the tree. However, it also matches `A-DIFFERENT-README` and `src/DO-NOT-README`, or any other file whose name ends with `README`.
`src/README` | Matches `src\README` on Windows because all directory separators are rewritten as `/` in the canonical name before the glob is matched. This makes it much easier to write globs that work on both Unix and Windows.
`*.[ch]` | Matches every C source or header file in the tree at the root or at any depth. Again, this is (deliberately) different from Unix file globs and Windows wild cards.
## Where Globs are Used
### <a id="settings"></a>Settings that are Globs
These settings are all lists of glob patterns:
:Setting |:Description
--------------------------------------------------------------------------------
`binary-glob` | Files that should be treated as binary files for committing and merging purposes
`clean-glob` | Files that the [`clean`][] command will delete without prompting or allowing undo
`crlf-glob` | Files in which it is okay to have `CR`, `CR`+`LF` or mixed line endings. Set to "`*`" to disable CR+LF checking
`crnl-glob` | Alias for the `crlf-glob` setting
`encoding-glob` | Files that the [`commit`][] command will ignore when issuing warnings about text files that may use another encoding than ASCII or UTF-8. Set to "`*`" to disable encoding checking
`ignore-glob` | Files that the [`add`][], [`addremove`][], [`clean`][], and [`extras`][] commands will ignore
`keep-glob` | Files that the [`clean`][] command will keep
All may be [versioned, local, or global](settings.wiki). Use `fossil
settings` to manage local and global settings, or a file in the
repository's `.fossil-settings/` folder at the root of the tree named
for each for versioned setting.
Using versioned settings for these not only has the advantage that
they are tracked in the repository just like the rest of your project,
but you can more easily keep longer lists of more complicated glob
patterns than would be practical in either local or global settings.
The `ignore-glob` is an example of one setting that frequently grows
to be an elaborate list of files that should be ignored by most
commands. This is especially true when one (or more) IDEs are used in
a project because each IDE has its own ideas of how and where to cache
information that speeds up its browsing and building tasks but which
need not be preserved in your project's history.
Although the `empty-dirs` setting is not a list of glob patterns as
such, it is *parsed* that way for consistency among the settings,
allowing [the list parsing rules above](#syntax) to apply.
### <a id="commands"></a>Commands that Refer to Globs
Many of the commands that respect the settings containing globs have
options to override some or all of the settings. These options are
usually named to correspond to the setting they override, such as
`--ignore` to override the `ignore-glob` setting. These commands are:
* [`add`][]
* [`addremove`][]
* [`changes`][]
* [`clean`][]
* [`commit`][]
* [`extras`][]
* [`merge`][]
* [`settings`][]
* [`status`][]
* [`touch`][]
* [`unset`][]
The commands [`tarball`][] and [`zip`][] produce compressed archives of a
specific checkin. They may be further restricted by options that
specify glob patterns that name files to include or exclude rather
than archiving the entire checkin.
The commands [`http`][], [`cgi`][], [`server`][], and [`ui`][] that
implement or support with web servers provide a mechanism to name some
files to serve with static content where a list of glob patterns
specifies what content may be served.
[`add`]: /help?cmd=add
[`addremove`]: /help?cmd=addremove
[`changes`]: /help?cmd=changes
[`clean`]: /help?cmd=clean
[`commit`]: /help?cmd=commit
[`extras`]: /help?cmd=extras
[`merge`]: /help?cmd=merge
[`settings`]: /help?cmd=settings
[`status`]: /help?cmd=status
[`touch`]: /help?cmd=touch
[`unset`]: /help?cmd=unset

[`zip`]: /help?cmd=zip
[`http`]: /help?cmd=http
[`cgi`]: /help?cmd=cgi
[`server`]: /help?cmd=server
[`ui`]: /help?cmd=ui
### Web Pages that Refer to Globs
The [`/timeline`][] page supports the query parameter `chng=GLOBLIST` that
names a list of glob patterns defining which files to focus the
timeline on. It also has the query parameters `t=TAG` and `r=TAG` that
names a tag to focus on, which can be configured with `ms=STYLE` to
use a glob pattern to match tag names instead of the default exact
match or a couple of other comparison styles.
The pages [`/tarball`][] and [`/zip`][] generate compressed archives
of a specific checkin. They may be further restricted by query
parameters that specify glob patterns that name files to include or
exclude rather than taking the entire checkin.
[`/timeline`]: /help?cmd=/timeline
[`/tarball`]: /help?cmd=/tarball
[`/zip`]: /help?cmd=/zip
## Platform Quirks
Fossil glob patterns are based on the glob pattern feature of POSIX
shells. Fossil glob patterns also have a quoting mechanism, discussed
[above](#syntax). Because other parts of your operating system may interpret glob
patterns and quotes separately from Fossil, it is often difficult to
give glob patterns correctly to Fossil on the command line. Quotes and
special characters in glob patterns are likely to be interpreted when
given as part of a `fossil` command, causing unexpected behavior.
These problems do not affect [versioned settings files](settings.wiki)
or Admin → Settings in Fossil UI. Consequently, it is better to
set long-term `*-glob` settings via these methods than to use `fossil
settings` commands.
That advice does not help you when you are giving one-off glob patterns
in `fossil` commands. The remainder of this section gives remedies and
workarounds for these problems.
### <a id="posix"></a>POSIX Systems
If you are using Fossil on a system with a POSIX-compatible shell
— Linux, macOS, the BSDs, Unix, Cygwin, WSL etc. — the shell
may expand the glob patterns before passing the result to the `fossil`
executable.
Sometimes this is exactly what you want. Consider this command for
example:
$ fossil add RE*
If you give that command in a directory containing `README.txt` and
`RELEASE-NOTES.txt`, the shell will expand the command to:
$ fossil add README.txt RELEASE-NOTES.txt
…which is compatible with the `fossil add` command's argument list,
which allows multiple files.
Now consider what happens instead if you say:
$ fossil add --ignore RE* src/*.c
This *does not* do what you want because the shell will expand both `RE*`
and `src/*.c`, causing one of the two files matching the `RE*` glob
pattern to be ignored and the other to be added to the repository. You
need to say this in that case:
$ fossil add --ignore 'RE*' src/*.c
The single quotes force a POSIX shell to pass the `RE*` glob pattern
through to Fossil untouched, which will do its own glob pattern
matching. There are other methods of quoting a glob pattern or escaping
its special characters; see your shell's manual.
Beware that Fossil's `--ignore` option does not override explicit file
mentions:
$ fossil add --ignore 'REALLY SECRET STUFF.txt' RE*
You might think that would add everything beginning with `RE` *except*
for `REALLY SECRET STUFF.txt`, but when a file is both given
explicitly to Fossil and also matches an ignore rule, Fossil asks what
you want to do with it in the default case; and it does not even ask
if you gave the `-f` or `--force` option along with `--ignore`.
The spaces in the ignored file name above bring us to another point:
such file names must be quoted in Fossil glob patterns, lest Fossil
interpret it as multiple glob patterns, but the shell interprets
quotation marks itself.
One way to fix both this and the previous problem is:
$ fossil add --ignore "'REALLY SECRET STUFF.txt'" READ*
The nested quotation marks cause the inner set to be passed through to
Fossil, and the more specific glob pattern at the end — that is,
`READ*` vs `RE*` — avoids a conflict between explicitly-listed
files and `--ignore` rules in the `fossil add` command.
Another solution would be to use shell escaping instead of nested
quoting:
$ fossil add --ignore "\"REALLY SECRET STUFF.txt\"" READ*
It bears repeating that the two glob patterns here are not interpreted
the same way when running this command from a *subdirectory* of the top
checkout directory as when running it at the top of the checkout tree.
If these files were in a subdirectory of the checkout tree called `doc`
and that was your current working directory, the command would instead
have to be:
$ fossil add --ignore "'doc/REALLY SECRET STUFF.txt'" READ*
The Fossil glob pattern still needs the `doc/` prefix because
Fossil always interprets glob patterns from the base of the checkout
directory, not from the current working directory as POSIX shells do.
When in doubt, use `fossil status` after running commands like the
above to make sure the right set of files were scheduled for insertion
into the repository before checking the changes in. You never want to
accidentally check something like a password, an API key, or the
private half of a public cryptographic key into Fossil repository that
can be read by people who should not have such secrets.
### <a id="windows"></a>Windows
Before we get into Windows-specific details here, beware that this
section does not apply to the several Microsoft Windows extensions that
provide POSIX semantics to Windows, for which you want to use the advice
in [the POSIX section above](#posix) instead:
* the ancient and rarely-used [Microsoft POSIX subsystem][mps];
* its now-discontinued replacement feature, [Services for Unix][sfu]; or
* their modern replacement, the [Windows Subsystem for Linux][wsl]
[mps]: https://en.wikipedia.org/wiki/Microsoft_POSIX_subsystem
[sfu]: https://en.wikipedia.org/wiki/Windows_Services_for_UNIX
[wsl]: https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux
(The latter is sometimes incorrectly called "Bash on Windows" or "Ubuntu
on Windows," but the feature provides much more than just Bash or Ubuntu
for Windows.)
Neither standard Windows command shell — `cmd.exe` or PowerShell
— expands glob patterns the way POSIX shells do. Windows command
shells rely on the command itself to do the glob pattern expansion. The
way this works depends on several factors:
* the version of Windows you are using
* which OS upgrades have been applied to it
* the compiler that built your Fossil executable
* whether you are running the command interactively
* whether the command is built against a runtime system that does this
at all
* whether the Fossil command is being run from a file named `*.BAT` vs
being named `*.CMD`
Usually (but not always!) the C runtime library that your `fossil.exe`
executable is built against does this glob expansion on Windows so the
program proper does not have to. This may then interact with the way the
Windows command shell you’re using handles argument quoting. Because of
these differences, it is common to find perfectly valid Fossil command
examples that were written and tested on a POSIX system which then fail
when tried on Windows.
The most common problem is figuring out how to get a glob pattern passed
on the command line into `fossil.exe` without it being expanded by the C
runtime library that your particular Fossil executable is linked to,
which tries to act like [the POSIX systems described above](#posix). Windows is
not strongly governed by POSIX, so it has not historically hewed closely
to its strictures.
For example, consider how you would set `crlf-glob` to `*` in order to
get normal Windows text files with CR+LF line endings past Fossil's
"looks like a binary file" check. The naïve approach will not work:
C:\...> fossil setting crlf-glob *
The C runtime library will expand that to the list of all files in the
current directory, which will probably cause a Fossil error because
Fossil expects either nothing or option flags after the setting's new
value, not a list of file names. (To be fair, the same thing will happen
on POSIX systems, only at the shell level, before `.../bin/fossil` even
gets run by the shell.)
Let's try again:
C:\...> fossil setting crlf-glob '*'
Quoting the argument like that will work reliably on POSIX, but it may
or may not work on Windows. If your Windows command shell interprets the
quotes, it means `fossil.exe` will see only the bare `*` so the C
runtime library it is linked to will likely expand the list of files in
the current directory before the `setting` command gets a chance to
parse the command line arguments, causing the same failure as above.
This alternative only works if you’re using a Windows command shell that
passes the quotes through to the executable *and* you have linked Fossil
to a C runtime library that interprets the quotes properly itself,
resulting in a bare `*` getting clear down to Fossil’s `setting` command
parser.
An approach that *will* work reliably is:
C:\...> echo * | fossil setting crlf-glob --args -
This works because the built-in Windows command `echo` does not expand its
arguments, and the `--args -` option makes Fossil read further command
arguments from its standard input, which is connected to the output
of `echo` by the pipe. (`-` is a common Unix convention meaning
"standard input," which Fossil obeys.) A [batch script][fng.cmd] to automate this trick was
posted on the now-inactive Fossil Mailing List.
[fng.cmd]: https://www.mail-archive.com/fossil-users@lists.fossil-scm.org/msg25099.html
(Ironically, this method will *not* work on POSIX systems because it is
not up to the command to expand globs. The shell will expand the `*` in
the `echo` command, so the list of file names will be passed to the
`fossil` standard input, just as with the first example above!)
Another (usually) correct approach which will work on both Windows and
POSIX systems:
C:\...> fossil setting crlf-glob *,
This works because the trailing comma prevents the glob pattern from
matching any files, unless you happen to have files named with a
trailing comma in the current directory. If the pattern matches no
files, it is passed into Fossil's `main()` function as-is by the C
runtime system. Since Fossil uses commas to separate multiple glob
patterns, this means "all files from the root of the Fossil checkout
directory downward and nothing else," which is of course equivalent to
"all managed files in this repository," our original goal.
## Experimenting
To preview the effects of command line glob pattern expansion for
various glob patterns (unquoted, quoted, comma-terminated), for any
combination of command shell, OS, C run time, and Fossil version,
precede the command you want to test with [`test-echo`][] like so:
$ fossil test-echo setting crlf-glob "*"
C:\> echo * | fossil test-echo setting crlf-glob --args -
The [`test-glob`][] command is also handy to test if a string
matches a glob pattern.
[`test-echo`]: /help?cmd=test-echo
[`test-glob`]: /help?cmd=test-glob
## Converting `.gitignore` to `ignore-glob`
Many other version control systems handle the specific case of
ignoring certain files differently from Fossil: they have you create
individual "ignore" files in each folder, which specify things ignored
in that folder and below. Usually some form of glob patterns are used
in those files, but the details differ from Fossil.
In many simple cases, you can just store a top level "ignore" file in
`.fossil-settings/ignore-glob`. But as usual, there will be lots of
edge cases.
[Git has a rich collection of ignore files][gitignore] which
accumulate rules that affect the current command. There are global
files, per-user files, per workspace unmanaged files, and fully
version controlled files. Some of the files used have no set name, but
are called out in configuration files.
[gitignore]: https://git-scm.com/docs/gitignore
In contrast, Fossil has a global setting and a local setting, but the local setting
overrides the global rather than extending it. Similarly, a Fossil
command's `--ignore` option replaces the `ignore-glob` setting rather
than extending it.
With that in mind, translating a `.gitignore` file into
`.fossil-settings/ignore-glob` may be possible in many cases. Here are
some of features of `.gitignore` and comments on how they relate to
Fossil:
* "A blank line matches no files...": same in Fossil.
* "A line starting with # serves as a comment...": same in Fossil, including
the possibility of escaping an initial `#` with a backslash to allow globs
beginning with a hash.
* "Trailing spaces are ignored unless they are quoted..." is similar
in Fossil. All whitespace before and after a glob is trimmed in
Fossil unless quoted with single or double quotes. Git uses
backslash quoting instead, which Fossil does not.
* "An optional prefix "!" which negates the pattern...": not in
Fossil.
* Git's globs are relative to the location of the `.gitignore` file:
Fossil's globs are relative to the root of the workspace.
* Git's globs and Fossil's globs treat directory separators
differently. Git includes a notation for zero or more directories
that is not needed in Fossil.
### Example
In a project with source and documentation:
work
+-- doc
+-- src
The file `doc/.gitignore` might contain:
# Finished documents by pandoc via LaTeX
*.pdf
# Intermediate files
*.tex
*.toc
*.log
*.out
*.tmp
Entries in `.fossil-settings/ignore-glob` with similar effect, also
limited to the `doc` folder:
doc/*.pdf
doc/*.tex, doc/*.toc, doc/*.log, doc/*.out, doc/*.tmp

# Glossary
There are several terms-of-art in Fossil that have specific meanings
which are either not immediately obvious to an outsider or which have
technical associations that can lead someone to either use the terms
incorrectly or to get the wrong idea from someone using those terms
correctly. We hope to teach users how to properly “speak Fossil†with
this glossary.
The bullet-point lists following each definition are meant to be
clarifying and illustrative. They are not part of the definitions
themselves.
## <a id="project"></a>Project
A collection of one or more computer files that serve some conceptually
unified purpose, which purpose changes and evolves over time, with the
history of that project being a valuable record.
* We qualify the Fossil definition of this common word like this to
set aside cases where a zip file or tarball would suffice. If you
can pack your project up into such an archive once and be done with
it, Fossil is overkill.
And yet that is often just the beginning, since there is often a
need for something to be changed, so now you have “version 2†of the
archive file. If you can foresee yourself creating versioned archive
files for your project, then you probably should be using Fossil for
it instead, then using Fossil’s [zip] or [tarball] command to
automatically produce archives of the latest version rather than
manually produce and track versions of the archive. The web version
of these commands ([`/zip`][zw] and [`/tarball`][tw]) are
particularly useful for public distribution of the latest version of
a project’s files.
* Fossil was designed to host the SQLite software project, which is
comprised of source code, makefiles, scripts, documentation files,
and so forth. Fossil is also useful for many other purposes, such as
a fiction book project where each chapter is held in a separate file
and assembled into a finished whole deliverable.
* We speak of projects being more than one file because even though
Fossil can be made to track the history of a single file, it is far
more often the case that when you get to something of a scale
sufficient to be called a “project,†there is more than one
version-tracked file involved, if not at the start, then certainly
by the end of the project.
To take the example of a fiction book above, instead of putting each
chapter in a separate file, you could use a single AsciiDoc file for
the entire book project rather than make use of its [include
facility][AIF] to assemble it from chapter files, since that does at
least solve the [key problems][IFRS] inherent in version-tracking
something like Word’s DOCX format with Fossil instead.
While Fossil will happily track the single file containing the prose
of your book project for you, you’re still likely to want separate
files for the cover artwork, a style sheet for use in converting the
source document to HTML, scripts to convert that intermediate output
to PDF and ePub in a reliably repeatable fashion, a `README` file
containing instructions to the printing house, and so forth.
* Fossil requires that all the files for a project be collected into a
single directory hierarchy, owned by a single user with full rights
to modify those files. Fossil is not a good choice for managing a
project that has files scattered hither and yon all over the file
system, nor of collections of files with complicated ownership and
access rights.
A project made of an operating system
installation’s configuration file set is not a good use of Fossil,
because you’ll have all of your OS’s *other* files intermixed.
Worse, Fossil doesn’t track OS permissions, so even if you were to
try to use Fossil as a system deployment tool by archiving versions
of the OS configuration files and then unpacking them on a new
system, the extracted project files would have read/write access by
the user who did the extraction, which probably isn’t what you were
wanting.
Even with these problems aside, do you really want a `.fslckout`
SQLite database at the root of your filesystem? Are you prepared for
the consequences of saying `fossil clean --verily` on such a system?
You can constrain that with [the `ignore-glob` setting][IGS], but
are you prepared to write and maintain all the rules needed to keep
Fossil from blowing away the untracked portions of the file system?
We believe Fossil is a poor choice for a whole-system configuration
backup utility.
As a counterexample, a project tracking your [Vim] configuration
history is a much better use of Fossil, because it’s all held within
`~/.vim`, and your user has full rights to that subdirectory.

## Repository <a id="repository" name="repo"></a>
A single file that contains all historical versions of all files in a
project, which can be [cloned] to other machines and
[synchronized][sync] with them. Jargon: repo.
* A Fossil repo is similar to an archive file in that it is a single
file that stores compressed versions of one or more files. Files can be
extracted from the repo, and new files can be added to the repo,
but a Fossil repo has other capabilities
above and beyond what simple archive formats can do.
* Fossil does not care what you name your repository files, though
we do suggest “`.fossil`†as a standard extension. There is
only one place in Fossil where that convention is required, being the
[`fossil server DIRECTORY`][svrcmd] command, since it serves up
`*.fossil` files from `DIRECTORY`. If you don’t use that feature,
you can name your repo files anything you like.
* Cloned and synced repos redundantly store all available information
about that project, so if any one repo is lost, all of the cloned
historical content of the project as of the last sync is preserved
in each surviving repo.
Each user generally clones the project repository down to each
computer they use to participate in that project, and there is
usually at least one central host for the project as well, so there
is usually plenty of redundancy in any given Fossil-based project.
That said, a Fossil repository clone is a backup only in a limited
sense, because some information can’t be cloned, some doesn’t sync
by default, and some data is neither clonable nor syncable. We cover
these limitations and the workarounds for them in a separate
document, [Backing Up a Remote Fossil Repository][backup].
* Rather than be a backup, a Fossil repository clone is a
communication method for coordinating work on the project among
multiple machines and users: local work done against one repository
is communicated up to its parent repository on the next sync, and
work done on other repositories that were previously synced up to
that parent get pulled down into the local repo clone.
This bidirectional sync is automatic and on by default in Fossil.
You can [disable it][asdis], or you can [push] or [pull]
unidirectionally, if you wish.
The Fossil philosophy is that all project information resides in
each clone of the repository. In the ideal world, this would occur
instantly and automatically, but in actual use, Fossil falls
somewhat short of that mark. Some limitations are simply
technological: a given clone may be temporarily out of communication
with its parent repository, network delays exist, and so forth.
Fossil is [an AP mode system][CAP]. (This is sometimes called
“eventual consistency.â€) Other cases come down to administrative
necessity, as covered in [the backup doc][backup].
* Fossil doesn’t require that you have redundant clones. Whether you
do or not is a local decision based on usage needs, communication
requirements, desire for backups, and so forth.
* Fossil doesn’t care where the repositories are stored, but we
recommend keeping them all in a single subdirectory such as
"`~/fossils`" or "`%USERPROFILE%\Fossils`". A flat set of files
suffices for simple purposes, but you may have use for something
more complicated. This author uses a scheme like the following on
mobile machines that shuttle between home and the office:
``` pikchr toggle indent
box "~/museum/" fit
move right 0.1
line right dotted
move right 0.05
box invis "where one stores valuable fossils" ljust
arrow down 50% from first box.s then right 50%
box "work/" fit
move right 0.1
line dotted
move right 0.05
box invis "projects from $DAYJOB" ljust

box "home/" fit
move right 0.1
line dotted right until even with previous line.end
move right 0.05
box invis "personal at-home projects" ljust
arrow down 50% from 2nd vertex of previous arrow then right 50%
box "other/" fit
move right 0.1
line dotted right until even with previous line.end
move right 0.05
box invis "clones of Fossil itself, SQLite, etc." ljust
```

## Version / Revision / Hash / UUID <a id="version" name="hash"></a>
These terms all mean the same thing: a long hexadecimal
[SHA hash value](./hashes.md) that uniquely identifies a particular
[check-in](#ci).
We’ve listed the alternatives in decreasing preference order:
* **Version** and **revision** are near-synonyms in common usage.
Fossil’s code and documentation use both interchangeably because
Fossil was created to manage the development of the SQLite project,
which formerly used [CVS], the Concurrent Versions System. CVS in
turn started out as a front-end to [RCS], the Revision Control
System, but even though CVS uses “version†in its name, it numbers
check-ins using a system derived from RCS’s scheme, which it calls
“Revisions†in user-facing output. Fossil inherits this confusion
honestly.
* **Hash** refers to the [SHA1 or SHA3-256 hash](./hashes.md) of the
content of the checked-in data, uniquely identifying that version of
the managed files. It is a strictly correct synonym, used more often
in low-level contexts than the term “version.â€
* **UUID** is a deprecated term still found in many parts of the
Fossil internals and (decreasingly) its documentation. The problem
with using this as a synonym for a Fossil-managed version of the
managed files is that there are [standards][UUID] defining the
format of a “UUID,†none of which Fossil follows, not even the
[version 4][ruuid] (random) format, the type of UUID closest in
meaning and usage to a Fossil hash.(^A pre-Fossil 2.0 style SHA1
hash is 160 bits, not the 128 bits many people expect for a proper
UUID, and even if you truncate it to 128 bits to create a “good
enough†version prefix, the 6 bits reserved in the UUID format for
the variant code cannot make a correct declaration except by a
random 1:64 chance. The SHA3-256 option allowed in Fossil 2.0 and
higher doesn’t help with this confusion, making a Fossil version
hash twice as large as a proper UUID. Alas, the term will never be
fully obliterated from use since there are columns in the Fossil
repository format that use the obsolete term; we cannot change this
without breaking backwards compatibility.)
You will find all of these synonyms used in the Fossil documentation.
Some day we may settle on a single term, but it doesn’t seem likely.

## Check-in <a id="check-in" name="ci"></a>
A [version] of the project’s files that have been committed to the
[repository]; as such, it is sometimes called a “commit†instead. A
check-in is a snapshot of the project at an instant in time, as seen from
a single [check-out’s](#co) perspective. It is sometimes styled
“`CHECKIN`â€, especially in command documentation where any
[valid check-in name][ciname] can be used.
* There is a harmless conflation of terms here: any of the various
synonyms for [version] may be used where “check-in†is more accurate,
and vice versa, because there is a 1:1 relation between them. A
check-in *has* a version, but a version suffices to uniquely look up
a particular commit.[^snapshot]
* Combining both sets of synonyms results in a list of terms that is
confusing to new Fossil users, but it’s easy
enough to internalize the concepts. [Committing][commit] creates a
*commit.* It may also be said to create a checked-in *version* of a
particular *revision* of the project’s files, thus creating an
immutable *snapshot* of the project’s state at the time of the
commit. Fossil users find each of these different words for the
same concept useful for expressive purposes among ourselves, but to
Fossil proper, they all mean the same thing.
* Check-ins are immutable.
* Check-ins exist only inside the repository. Contrast a
[check-out](#co).
* Check-ins may have [one or more names][ciname], but only the
[hash] is globally unique, across all time; we call it the check-in’s
canonical name. The other names are either imprecise, contextual, or
change their meaning over time and across [repositories].
[^snapshot]: You may sometimes see the term “snapshot†used as a synonym
for a check-in or the version number identifying said check-in. We
must warn against this usage because there is a potential confusion
here: [the `stash` command][stash] uses the term “snapshot,†as does
[the `undo` system][undo] to make a distinction with check-ins.
Nevertheless, there is a conceptual overlap here between Fossil and
systems that do use the term “snapshot,†the primary distinction being
that Fossil will capture only changes to files you’ve [added][add] to
the [repository], not to everything in [the check-out directory](#co)
at the time of the snapshot. (Thus [the `extras` command][extras].)
Contrast a snapshot taken by a virtual machine system or a
[snapshotting file system][snfs], which captures changes to everything
on the managed storage volume.
[add]: /help?cmd=add
[ciname]: ./checkin_names.wiki
[extras]: /help?cmd=extras
[stash]: /help?cmd=stash
[undo]: /help?cmd=undo
## Check-out <a id="check-out" name="co"></a>
A set of files extracted from a [repository] that represent a
particular [check-in](#ci) of the [project](#project).
* Unlike a check-in, a check-out is mutable. It may start out as a
version of a particular check-in extracted from the repository, but
the user is then free to make modifications to the checked-out
files. Once those changes are formally [committed][commit], they
become a new immutable check-in, derived from its parent check-in.
* You can switch from one check-in to another within a check-out
directory by passing those names to [the `fossil update`
command][update].
* Check-outs relate to repositories in a one-to-many fashion: it is
common to have a single repo clone on a machine but to have it
[open] in [multiple working directories][mwd]. Check-out directories
are associated with the repos they were created from by settings
stored in the check-out directory. This is in the `.fslckout` file on
POSIX type systems, but for historical compatibility reasons, it’s
called `_FOSSIL_` by native Windows builds of Fossil.
(Contrast the Cygwin and WSL Fossil binaries, which use POSIX file
naming rules.)
* In the same way that one cannot extract files from a zip archive
without having a copy of that zip file, one cannot make check-outs
without access to the repository file or a clone thereof.
* Because a Fossil repository is an SQLite database file, the same
rules for avoiding data corruption apply to it. In particular, it is
[nearly a hard requirement][h2cflp] that the repository clone be on
the same machine as the one where you make check-outs and the
subsequent check-ins.
That said, the relative locations of the repo and the check-out
within the local file system are arbitrary. The repository may be
located inside the folder holding the check-out, but it certainly
does not have to be, and it usually is not. As an example, [the
Fossil plugin for Visual Studio Code][fpvsc] defaults to storing the
repo clone within the project directory as a file called `.fsl`, but
this is because VSCode’s version control features assume it’s being
used with Git, where the repository is the `.git` subdirectory
contents. With Fossil, [different check-out workflows][cwork] are
preferred.

## <a id="docs"></a>Embedded Documentation
Serving as an alternative to Fossil’s built-in [wiki], the [embedded
documentation feature][edoc] stores the same type of marked-up text
files, but under Fossil’s powerful version control features.
* The simple rule for determining whether to use the wiki or embedded
docs for any given document is whether the content is considered
“evergreen,†as with a Wikipedia article.
While Fossil’s wiki feature does store the history of each
document’s changes, Fossil always presents the current version of
the document unless you manually go out of your way to dig back into
the history. Then, having done so, links from that historical
version of the wiki document take you to the current versions of the
target documents, not to the version contemporaneous with the source
document.
The consequence is that if you say something like…
$ fossil up 2020-04-01
$ fossil ui --page wcontent
…you will **not** see the list of wiki articles as of April Fool’s Day in 2020, but
instead the list of *current* wiki article versions, the same as if you ran it
from a check-out of the tip-of-trunk.
Contrast embedded docs, which are not only version-controlled as
normal files are in Fossil, they participate in all the tagging,
branching, and other versioning features. There are several
consequences of this, such as that Fossil’s [special check-in
names][ciname] work with embedded doc URLs:
* <p>If you visit an embedded doc as `/doc/release/file.md` and
then click on a relative link from that document, you will remain on
the release branch. This lets you see not only the release
version of a software project but also the documentation as of
that release.</p>
* <p>If you visit `/doc/2020-04-01/file.md`, you will not only
pull up the version of `file.md` as of that date, relative links
will take you to contemporaneous versions of those embedded docs
as well.</p>
* <p>If you say `fossil up 2020-04-01 && fossil ui` and then visit
`/doc/ckout/file.md`, you’ll not only see the checked-out
version of the file as of that date, relative links will show
you other files within that checkout.</p>
* Fossil’s wiki presents a flat list of articles, while embedded docs
are stored in the repository’s file hierarchy, a powerful
organizational tool well-suited to complicated documentation.
* Your repository’s Home page is a good candidate for the wiki, as is
documentation meant for use only with the current version of the
repository’s contents.
* If you are at all uncertain whether to use the wiki or the embedded
documentation feature, prefer the latter, since it is inherently
more powerful, and when you use the [`/fileedit` feature][fef], the
workflow is scarcely different from using the wiki.
(This very file is embedded documentation: clone
[Fossil’s self-hosting repository][fshr] and you will find it as
`www/glossary.md`.)
[edoc]: ./embeddeddoc.wiki
[fef]: ./fileedit-page.md
[fshr]: ./selfhost.wiki
[wiki]: ./wikitheory.wiki
## <a id="cap"></a>Capability
Fossil includes a powerful [role-based access control system][rbac]
which affects which users have permission to do certain things within a given
[repository]. You can read more about this complex topic
[here](./caps/).
Some people — and indeed certain parts of Fossil’s own code — use the
term “permissions†instead, but since [operating system file permissions
also play into this](./caps/#webonly), we prefer the term “capabilitiesâ€
(or “caps†for short) when talking about Fossil’s RBAC system to avoid a
confusion here.

# Fossil grep vs POSIX grep
As of Fossil 2.7, there is a `grep` command which acts roughly like
POSIX's `grep -E` over all historical versions of one or more managed files.
This document explains the commonalities and divergences between [POSIX
`grep`](http://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html)
and Fossil `grep`.
## Options
Fossil `grep` implements about half of the options specified for
POSIX `grep`:
| Option | Meaning
|--------|-------------------------------------------------------------
| `-c` | report the count of matches rather than the matched text
| `-i` | ignore case in matches
| `-l` | list a checkin ID prefix for matching historical versions of the file
| `-q` | no output; return only a status code indicating the success of the match
| `-s` | suppress error output about missing files
| `-v` | invert the sense of the match
That leaves several divergences at the option level from POSIX `grep`:
* You cannot give more than one pattern, as with `grep -e` or
`grep -f`.
* There is no equivalent of `grep -F` to do literal fixed-string
matches only.
* There is no `-x` option for doing a whole-line match.
* `fossil grep -l` does not do precisely the same thing as POSIX
`grep -l`: it lists checkin ID prefixes, not file names.
* Fossil always gives the line number in its output, which is to say
that it acts like `grep -n`. There is no way to disable the line
number in `fossil grep` output.
Patches to remove those limitations will be thoughtfully considered.
Fossil `grep` doesn’t support any of the GNU and BSD `grep` extensions.
For instance, it doesn’t support the common `-R` extension to POSIX,
which would presumably search a subtree of managed files. If Fossil does
one day get this feature, it would have a different option letter, since
`-R` in Fossil has a different meaning, by convention. Until then, you
can get the same effect on systems with a POSIX shell like so:
$ fossil grep COMMAND: $(fossil ls src)
If you run that in a check-out of the [Fossil self-hosting source
repository][fshsr], that returns the first line of the built-in
documentation for each Fossil command, across all historical versions.
Fossil `grep` has extensions relative to these other `grep` standards,
such as `--verbose` to print each checkin ID considered, regardless of
whether it matches. This one is noteworthy here because the behavior
used to be under `-v` before we reassigned it to give POSIX-like `grep
-v` behavior.
[fshsr]: ./selfhost.wiki
## Regular Expression Dialect
Fossil contains a built-in regular expression engine implementing a
subset of the [POSIX extended regular expression][ere] dialect:
[ere]: https://en.wikipedia.org/wiki/Regular_expression#POSIX_extended
| Atom | Meaning
|---------|-------------------------------------------------------------
| `X*` | zero or more occurrences of X
| `X+` | one or more occurrences of X
| `X?` | zero or one occurrences of X
| `X{p,q}`| between p and q occurrences of X, inclusive
| `(X)` | match X
| <tt>X\|Y</tt>| X or Y
| `^X` | X occurring at the beginning of a line
| `X$` | X occurring at the end of a line
| `.` | Match any single character
| `\c` | Character `c` where `c` is one of <tt>{}()[]\|\*+?.\\</tt>
| `\c` | C-language escapes for `c` in `afnrtv`. ex: `\t` or `\n`
| `\uXXXX`| Where XXXX is exactly 4 hex digits, Unicode value XXXX
| `\xXX` | Where XX is exactly 2 hex digits, Unicode value XX
| `[abc]` | Any single character from the set `abc`
| `[^abc]`| Any single character not in the set `abc`
| `[a-z]` | Any single character in the range `a-z`
| `[^a-z]`| Any single character not in the range `a-z`
| `\b` | Word boundary
| `\w` | Word character: `[A-Za-z0-9_]`
| `\W` | Non-word character: `[^A-Za-z0-9_]`
| `\d` | Digit: `[0-9]`
| `\D` | Non-digit: `[^0-9]`
| `\s` | Whitespace character: `[ \t\r\n\v\f]`
| `\S` | Non-whitespace character: `[^ \t\r\n\v\f]`
There are several restrictions in Fossil `grep` relative to a fully
POSIX compatible regular expression engine. Among them are:
* There is currently no support for POSIX character classes such as
`[:lower:]`.
* Fossil `grep` does not currently attempt to take your operating
system's locale settings into account when doing this match. Since
Fossil has no way to mark a given file as having a particular
encoding, Fossil `grep` assumes the input files are in UTF-8 format.
This means Fossil `grep` will not work correctly if the files in
your repository are in an encoding that is not backwards-compatible
with ASCII, such as UTF-16. Partially compatible encodings such as
ISO 8859 should work with Fossil `grep` as long as you stick to
their ASCII-compatible subset.
The Fossil `grep` language is not a strict subset of POSIX extended
regular expressions. Some of the features documented above are
well-understood extensions to it, such as the "word" features `\b`, `\w`
and `\W`.
Fossil `grep` is based on the Unicode engine from [SQLite's FTS5
feature][fts5]. This means it does do things like Unicode-aware case
folding. Therefore, it is usually a user error to attempt to substitute
`[a-z]` for a lack of the POSIX character class `[:lower:]` if you are
grepping over pretty much any human written language other than English.
Use `fossil grep -i` instead, which does Unicode case folding.
[fts5]: https://www.sqlite.org/fts5.html
## Algorithm Details
Fossil `grep` uses a [nondeterministic finite automaton][nfa] for
matching, so the performance is bounded by ***O(nm)*** where ***n*** is
the size of the regular expression and ***m*** is the size of the input
string.
[nfa]: https://en.wikipedia.org/wiki/Nondeterministic_finite_automaton
In order to avoid [ReDoS attacks][redos], the Fossil regular expression
matcher was purposely written to avoid [implementation choices][rei]
which have the potential to require exponential evaluation time. This
constrains the possible feature set we can support in the Fossil `grep`
dialect. For instance, we are unlikely to ever add support for
[backtracking][bt].
[redos]: https://en.wikipedia.org/wiki/ReDoS
[rei]: https://en.wikipedia.org/wiki/Regular_expression#Implementations_and_running_times
[bt]: https://en.wikipedia.org/wiki/Backtracking
The `X{p,q}` operator expands to `p` copies of `X` followed by `q-p`
copies of `X?` before RE evaluation. The ***O(nm)*** performance bound
above remains true for this case, but realize that it applies to the RE
*after* this expansion, not to the form as given by the user. In other
words, as `q-p` increases, so does the RE evaluation time.

That application was unsuccessful, but still this list is a starting point for anyone looking for a place to start. We welcome newcomers, and invite developers to follow the simple [procedures for contributing to Fossil](./contribute.wiki). The [hacker how-to](./hacker-howto.wiki) is recommended reading. There are two implementations of the Fossil data model: * [the classic Fossil project](https://fossil-scm.org) , which is where this file is maintained and which is as of 2021 how everyone interacts with Fossil objects * [libfossil](https://fossil.wanderinghorse.net/r/libfossil), which is an independent project to manipulate Fossil objects from a library, or using commandline tools which are thin wrappers to the library As of 2021 the two implementations have an identical implementation of the Fossil data model, are 100% compatible in terms of data access since they use the same SQL, and are 100% binary compatible in terms of on-disk storage. The projects listed here are grouped by functionality - User Interface, Integration, Email, etc. If you are looking for something easy to start with, then depending where your interests lie, there are some small libfossil tasks and small features to work on in the UI. # UI, Look and Feel Tasks for those interested in graphic/web design: * Add a quote button to the Forum, such as [discussed in this thread](https://fossil-scm.org/forum/forumpost/7ad03cd73d) * Improve the documentation history-browsing page to enable selection of 2 arbitrary versions to diff, similar to the [Mediawiki history feature enabled on Wikipedia](https://en.wikipedia.org/w/index.php?title=Fossil_(software)&action=history) * Allow diffing of Forum posts * General touch-ups in the existing skins. This may, depending on how deep one cares to dig, require digging into C code to find, and potentially modify, how the HTML is generated. * Creation of one or more new skins. This does not specifically require any C know-how. * Complete per-feature CSS facilities in [the Inskinerator](https://tangentsoft.com/inskinerator/dir) and add features to the Inskinerator # Projects Relating to Fossil Integration * Fossil hooks for pipelines with CI/CD such as static analysis, Buildbot, Gerrit, Travis and Jenkins are not well-documented and may need some further development. Make this work better, with configuration examples * Create a [Pandoc](https://pandoc.org) filter that handles Fossil-style Markdown * Create a [Pandoc filter that handles Pikchr](https://groups.google.com/g/pandoc-discuss/c/zZSspnHHsg0?pli=1) (Pikchr can be used with many kinds of layout, not just Markdown) * Editor integration: [improve the Fossil VSCode plugin](https://marketplace.visualstudio.com/items?itemName=koog1000.fossil) or [create a Fossil plugin for Eclipse](https://marketplace.eclipse.org/taxonomy/term/26%2C31) * Develop a test suite for the draft JSON API in libfossil. This JSON API is a way of integrating many kinds of systems with Fossil * Re-implement the draft JSON API in libfossil to use the JSON capability in SQLite, now that SQLite has JSON. This is a large project and would start with feasibility analysis # Adding Inbound (Receiving) Email to Fossil This task involves designing a new feature and working with Fossil developers to see how it can be feasible in practice. Fossil can [send email alerts](./alerts.md), but cannot receive email at all. That is a good thing, because a complete [SMTP MTA](https://en.wikipedia.org/wiki/MTA) is complicated and requires constant maintenance, so Fossil should not try to be an MTA or ever listen to mail ports on the Internet. There is one specific type of email reception that make sense for Fossil to handle. When there is inbound mail related to a message that Fossil has previously generated with a unique hash, Fossil already knows the context of that message. An unknown sender cannot guess a valid hash although a malicious sender could of course find a way to receive a valid hash and then use that to gain access. The risk of automatic and non-specific spam is very low. A proposal to handle that would be to implement a Fossil command like this: ``` fossil email -R repo receive -t TYPE-OF-EMAIL -h HASH ``` Where the type of email would be one of a list something like this: * mail_bounce * ticket_reply * forum_reply This command is a non-network-aware [Mail Delivery Agent](https://en.wikipedia.org/wiki/Mail_delivery_agent), and would be called by an SMTP MTA such as Postfix, Courier or Exim. The MTA would need to be configured to recognise that this is an email intended for Fossil, and what type of email, and to extract its hash. People who configure MTAs are used to doing this sort of thing, but no doubt Fossil would include a sample [Postfix mail filter](http://www.postfix.org/FILTER_README.html#simple_filter) and an equivalent driver for Exim. The Fossil command would reject anything that doesn't look like a bounce it is expecting. It is not certain that this design is the best one to address the inbound mail problem. That is why the first part of this task is to find a workable design. # Work relating to the ticketing system in Fossil The Fossil SCM project uses tickets in a [somewhat unusual manner](https://fossil-scm.org/home/reportlist) because the social programming model has evolved to often use the Forum instead of ticketing. Other Fossil-using projects use tickets in a more traditional report-a-bug manner. So this means that the Fossil ticketing system user interface is underdeveloped. On the other hand, pretty much every software developer uses a ticketing system at some point in their workflow, and Fossil is intended to be usable by most developers. That means the ticketing system really needs to be further developed. The underlying technology for the Fossil ticketing system is guaranteed, so to improve it requires only user interface changes. Projects relating to the ticketing system include: * Improving the [Fossil cli for tickets](https://fossil-scm.org/forum/forumpost/d8e8a1cf92) which is confusing, as pointed out in that ticket. This is still classified as a "user interface" even though it isn't graphical. * Alternatively, instead of improving Fossil's cli, implement a comprehensive ticket commandline with [libfossil's primitives](https://fossil.wanderinghorse.net/r/libfossil/wiki/home), look under the f-apps/ directory. * Improving the Fossil web UI for ticketing, which is clunky to say the least. Fossil tries not be a heavy user of Javascript and Javascript libraries, but the wikiedit, chat and Forum code are all more advanced than ticketing, and have UI features that would improve ticketing * If there is an inbound email system as per the previous section "Adding Inbound (Receiving) Email to Fossil", then implement this system for ticketing # Tasks Requiring Fossil Data Model Knowledge The Fossil data model concepts are simple, but the implications are quite subtle and impressive. The data model is designed to [endure for centuries](./fileformat.wiki), be [easily accessible](./fossil-v-git.wiki#durable), and is [non-relational](./fossil-is-not-relational.md). You will need to understand the data model to work on the following tasks: * Add the ability to tag non-checkin artifacts, something supported by the data model but not the current CLI and UIs. This would open the door to numerous new features, such as "sticky" forum posts and per-file extended attributes. This could also relate to the RBAC system. * Implement "merge" and "stash" in libfossil * Analyse the different kinds of [split/export/shallow clone](https://fossil-scm.org/forum/forumpost/1aa4f8ea8c6f96) use cases for Fossil including [complete bifurcation](https://fossil-scm.org/forum/forumpost/6434a06871). There are many proposals, relating to many different use cases, and a good analysis would help us to work out what should be implemented, and what should be implemented in Fossil and what is instead a libfossil wrapper # Fossil is cool There are many reasons why Fossil is just plain cool: * Fossil is symbiotically connected with [SQL and SQLite](5631123d66d96) * Fossil is highly portable accross different operating systems * Fossil is the [only credible alternative to Git](./fossil-v-git.wiki) * Fossil is both ultra-long-term stable and has a high rate of development and new features * Fossil has thought deeply about Comp Sci principles including [CAP Theorem](./cap-theorem.md) and [whether Fossil is a blockchain](./blockchain.md) * Fossil has two independent implementations of the same data model: Fossil and libfossil and a lot, lot more, in the source, docs, forum and more. ``` pikchr center toggle // Click to see the rendered diagram this describes, // written in Fossil's built-in pikchr language, see https://pikchr.org // // based on pikchr script by Kees Nuyt, licensed // https://creativecommons.org/licenses/by-nc-sa/4.0/ scale = 1.0 eh = 0.5cm ew = 0.2cm ed = 2 * eh er = 0.4cm lws = 4.0cm lwm = lws + er lwl = lwm + er ellipse height eh width ew fill Bisque color CadetBlue L1: line width lwl from last ellipse.n line "click for" bold above width lwm from last ellipse.s LV: line height eh down move right er down ed from last ellipse.n ellipse height eh width ew fill Bisque color CadetBlue L3: line "example of Fossil" bold width lws right from last ellipse.n to LV.end then down eh right ew line width lwm right from last ellipse.s then to LV.start move right er down ed from last ellipse.n ellipse height eh width ew fill Bisque color CadetBlue line width lwl right from last ellipse.n then to L1.end line "coolness" bold width lwl right from last ellipse.s then up eh ``` |

There is a loose hierarchy of terms used instead of “hash†in various parts of the Fossil UI, which we cover in the sections below. ## Names Several Fossil interfaces accept [a wide variety of check-in names][cin]: commit artifact hashes, ISO8601 date strings, branch names, etc. Fossil interfaces that accept any of these options usually document the parameter as “NAMEâ€, so we will use that form to refer to this specialized use. Artifact hashes are only one of many different types of NAME. We use the broad term “NAME†to refer to the whole class of options. We use more specific terms when we mean one particular type of NAME. ## Versions When an artifact hash refers to a specific commit, Fossil sometimes calls it a “VERSION,†a “commit ID,†or a “check-in ID.†We may eventually settle on one of these terms, but all three are currently in common use within Fossil’s docs, UI, and programming interfaces. A VERSION is a specific type of artifact hash, distinct from, let us say, a wiki article artifact hash. A unique prefix of a VERSION hash is itself a VERSION. That is, if your repository has exactly one commit artifact with a hash prefix of “abc123â€, then that is a valid version string as long as it remains unambiguous. ## <a id="uvh"></a>UUIDs Fossil uses the term “UUID†as a short alias for “artifact hash†in its internals. There are a few places where this leaks out into external interfaces, which we cover in the sections below. Going forward, we prefer one of the terms above in public interfaces instead. Whether this short alias is correct is debateable. One argument is that since "UUID" is an acronym for “Universally Unique Identifier,†and both SHA1 and SHA3-256 are larger and stronger than the 128-bit algorithms used by “proper†UUIDs, Fossil artifact hashes are *more universally unique*. It is therefore quibbling to say that Fossil UUIDs are not actually UUIDs. One wag suggested that Fossil artifact hashes be called MUIDs: multiversally unique IDs. The common counterargument is that the acronym “UUID†was created for [a particular type of universally-unique ID][uuid], with particular ASCII and bitfield formats, and with particular meaning given to certain of its bits. In that sense, no Fossil “UUID†can be used as a proper UUID. Be warned: attempting to advance the second position on the Fossil discussion forum will get you nowhere at this late date. We’ve had the debates, we’ve done the engineering, and we’ve made our evaluation. It’s a settled matter: internally within Fossil, “UUID†is defined as in this section’s leading paragraph. To those who remain unconvinced, “fixing†this would require touching almost every source code file in Fossil in a total of about a thousand separate locations. (Not exaggeration, actual data.) This would be a massive undertaking simply to deal with a small matter of terminology, with a high risk of creating bugs and downstream incompatibilities. Therefore, we are highly unlikely to change this ourselves, and we are also unlikely to accept a patch that attempts to fix it. ### Repository DB Schema The primary place where you find "UUID" in Fossil is in the `blob.uuid` table column, in code dealing with that column, and in code manipulating *other* data that *refers* to that column. This is a key lookup column in the most important Fossil DB table, so it influences broad swaths of the Fossil internals. For example, C code that refers to SQL result data on `blob.uuid` usually calls the variable `zUuid`. That value may then be inserted into a table like `ticket.tkt_uuid`, creating a reference back to `blob.uuid`, and then be passed to a function like `uuid_to_rid()`. There is no point renaming a single one of these in isolation: it would create needless terminology conflicts, making the code hard to read and understand, risking the creation of new bugs. You may have local SQL code that digs into the repository DB using these column names. While you may rest easy, assured now that we are highly unlikely to ever rename these columns, the Fossil repository DB schema is not considered an external user interface, and internal interfaces are subject to change at any time. We suggest switching to a more stable API: [the JSON API][japi], [`timeline.rss`][trss], [TH1][th1], etc. ### TH1 Scripting Interfaces Some [TH1][th1] interfaces expose Fossil internals flowing from `blob.uuid`, so “UUID†is a short alias for “artifact hash†in TH1. For example, the `$tkt_uuid` variable — available when [customizing the ticket system][ctkt] — is a ticket artifact hash, exposing the `ticket.tkt_uuid` column, which has a SQL relation to `blob.uuid`. TH1 is a longstanding public programming interface. We cannot rename its interfaces without breaking existing TH1 Fossil customizations. We are also unlikely to provide a parallel set of variables with “better†names, since that would create a mismatch with respect to the internals they expose, creating a different sort of developer confusion in its place. ### JSON API Parameters and Outputs [The JSON API][japi] frequently uses the term “UUID†in the same sort of way, most commonly in [artifact][jart] and [timeline][jtim] APIs. As with TH1, we can’t change this without breaking code that uses the JSON API as originally designed, so we take the same stance. ### `manifest.uuid` If you have [the `manifest` setting][mset] enabled, Fossil writes a file called `manifest.uuid` at the root of the check-out tree containing the commit hash for the current checked-out version. Because this is a public interface that existing code depends on, we are unwilling to rename the file.

<title>Hash Policy</title>
<h2>Executive Summary</h2>
<b>Or: How To Avoid Reading This Article</b>
There was much angst over the [http://www.shattered.io|SHAttered attack]
against SHA1 when it was announced in early 2017. If you are concerned
about this and its implications for Fossil, simply
[./quickstart.wiki#install|upgrade to Fossil 2.1 or later], and the
problem will go away. Everything will continue to work as before.
* Legacy repositories will continue working just as
they always have, without any conversions or upgrades.
* Historical check-ins will keep their same historical
SHA1 names.
* New check-ins will get more secure SHA3-256 hash names.
* Everything will continue as if nothing happened.
* Your workflow will be unchanged.
But if you are curious and want a deeper understanding of what is
going on, read on...
<h2>Introduction</h2>
The first snapshot-based distributed version control system
was [http://www.monotone.ca|Monotone]. Many of the ideas behind the design
of Fossil were copied from Monotone, including the use of a SHA1 hash to
assign names to artifacts. Git and Mercurial did the same thing.
The SHA1 hash algorithm is used only to create names for artifacts in Fossil
(and in Git, Mercurial, and Monotone). It is not used for security.
Nevertheless, when the [http://www.shattered.io|SHAttered attack] found
two different PDF files with the same SHA1 hash, many users learned that
"SHA1 is broken". They see that Fossil (and Git, Mercurial, and Monotone)
use SHA1 and they therefore conclude that "Fossil is broken". This is
not true, but it is a public relations problem. So the decision
was made to migrate Fossil away from SHA1.
This article describes how that migration is occurring.
<h2>Use Of Hardened SHA1</h2>
In Fossil version 2.0 ([/timeline?c=version-2.0|2017-03-03]),
the internal SHA1 implementation was changed from a generic
FIPS PUB 180-4 SHA1 implementation to a "Hardened SHA1"
[[https://github.com/cr-marcstevens/sha1collisiondetection|1]]
[[https://marc-stevens.nl/research/papers/C13-S.pdf|2]].
The Hardened SHA1 algorithm automatically detects when the artifact
being hashed is specifically designed to exploit the known weaknesses
in the SHA1 algorithm, and when it detects such an attack it changes
the hash algorithm (by increasing the number of rounds in the compression
function) to make the algorithm secure again. If the attack detection
gets a false-positive, that means that Hardened SHA1 will get a different
answer than the standard FIPS PUB 180-4 SHA1, but the creators of
Hardened SHA1 (see the second paper
[[https://marc-stevens.nl/research/papers/C13-S.pdf|2]])
report that the probability of a false-positive is vanishingly small -
less than 1 false positive out of 10<sup><font size=1>27</font></sup>
hashes.
Hardened SHA1 is slower (and a lot bigger) but Fossil does not do that
much hashing, so performance is not really an issue.
All versions of Fossil moving forward will use Hardened SHA1. So if
someone says "SHA1 is broken, and Fossil uses SHA1, therefore Fossil is
broken," you can rebut the argument by pointing out that Fossil uses
<em>Hardened SHA1</em>, not generic SHA1, and Hardened SHA1 is <em>not</em>
broken.
<h2>Support For SHA3-256</h2>
Prior to Fossil version 2.0 ([/timeline?c=version-2.0|2017-03-03]),
all artifacts in all Fossil repositories were named
by only a SHA1 hash.
Version 2.0 extended the [./fileformat.wiki|Fossil file format]
to allow artifacts to be named by either SHA1 or SHA3-256 hashes.
(SHA3-256 is the only variant of SHA3 that
Fossil uses for artifact naming, so for the remainder of this article
it will be called simply "SHA3". Similarly, "Hardened SHA1" will
be shortened to "SHA1" in the remaining text.)
To be clear: Fossil (version 2.0 and later)
allows the SHA1 and SHA3 hashes to be mixed within
the same repository. Older check-ins, created years ago,
continue to be named using their legacy SHA1 hashes while
newer check-ins are named using modern SHA3 hashes. There
is no need to "convert" a repository from SHA1 over to SHA3.
You can see this in Fossil itself. The recent
[9d9ef82234f63758] check-in uses a SHA3 hash whereas the older
[1669115ab9d05c18] check-in uses a SHA1 hash.
Other than permitting the use of SHA3 in addition to SHA1, there
were no file format changes in Fossil version 2.0 relative
to the previous version 1.37. Both Fossil 2.0 and Fossil 1.37 read
and write all the same repositories and sync with one another, as long
as none of the repositories contain artifacts named using SHA3. If
a repository does contain artifacts named using SHA3, Fossil 1.37 will
not know how to interpret those artifacts and will generate various warnings
and errors.
<h2>How Fossil Decides Which Hash Algorithm To Use For New Artifacts</h2>
If newer versions of Fossil are able to use either SHA1 or SHA3 to
name artifacts, which hash algorithm is actually used? That question
is answered by the "hash policy". These are the supported hash policies:
<table cellpadding=10>
<tr>
<td valign='top'>sha1</td>
<td>Name all new artifacts using the (Hardened) SHA1 hash algorithm.</td>
</tr>
<tr>
<td valign='top'>auto</td>
<td>Name new artifacts using the SHA1 hash algorithm, but if any
artifacts are encountered which are already named using SHA3, then
automatically switch the hash policy to "sha3"</td>
</tr>
<tr>
<td valign='top'>sha3</td>
<td>Name new artifacts using the SHA3 hash algorithm if the artifact
does not already have a SHA1 name. If the artifact already has a SHA1
name, then continue to use the older SHA1 name. Use SHA3 for new
artifacts that have never before been encountered.</td>
</tr>
<tr>
<td valign='top'>sha3-only</td>
<td>Name new artifacts using the SHA3 hash algorithm even if the artifact
already has a SHA1 name. In other words, force the use of SHA3. This can
cause some artifacts to be added to the repository twice, once under their
SHA1 name and again under their SHA3 name, but delta compression will
prevent that from causing repository size problems.</td>
</tr>
<tr>
<td valign='top'>shun-sha1</td>
<td>Like "sha3-only" but at this level do not accept a push of SHA1-named
artifacts. If another Fossil instance tries to push a SHA1-named artifact,
that artifact is discarded and ignored.
</tr>
</table>
For Fossil 2.0, and obviously also for Fossil 1.37 and before, the
only hash policy supported was the one now called "sha1", meaning that
all new artifacts were named
using a SHA1 hash.
Even though Fossil 2.0 added the capability of understanding SHA3 hashes, it
never actually generates any SHA3 hashes.
From Fossil 2.1 through 2.9, the default hash policy for legacy repositories
changed to "auto", meaning that
Fossil continued to generate only SHA1 hashes until it
encountered one artifact with a SHA3 hash. Once those older versions of
Fossil saw a single SHA3 hash, they
automatically switched to "sha3" mode and thereafter generated
only SHA3 hashes.
When a new repository is created by cloning, the hash policy is copied
from the parent.
For new repositories created using the
[/help?cmd=new|fossil new] command the default hash policy is "sha3".
That means new repositories
will normally hold nothing except SHA3 hashes. The hash policy for new
repositories can be overridden using the "--sha1" option to the
"fossil new" command.
If you are still on Fossil 2.1 through 2.9 but you want Fossil to go
ahead and start using SHA3 hashes, change the hash policy to
"sha3" using a command like this:
<verbatim>
fossil hash-policy sha3
</verbatim>
The next check-in will use a SHA3 hash, so that when that check-in is pushed
to colleagues, their clones will include the new SHA3-named artifact, so
their local Fossil instances will automatically convert their clones to
"sha3" mode as well.
Of course, if some members of your team stubbornly refuse to upgrade past
Fossil 1.37, you should avoid changing the hash policy and creating
artifacts with SHA3 names, because once you do that your recalcitrant
coworkers will no longer be able to collaborate.
<h2>A Pure SHA3 Future</h2>
Fossil 2.10 changed the default hash policy to "sha3" mode even for
legacy repositories, so if you
upgrade to the latest version of Fossil, all of your new artifacts will
use a SHA3 hash. Legacy SHA1 artifacts continue to use their original
names, but new artifacts will use SHA3 names. You might not even notice
this automatic change over to stronger hashes.
We decided to make the change to pure SHA3 since the last known distributor
of Fossil 1.x binaries — Debian 9 — was finally replaced in June 2019
by Debian 10, which included Fossil 2.8. All other known sources of
Fossil 1.x binaries upgraded well before that point.

<title>Fossil Tips And Usage Hints</title>
A collection of useful hints and tricks in no particular order:
1. Click on two nodes of any timeline graph in succession
to see a diff between the two versions.
2. Add the "--tk" option to "[/help?cmd=diff | fossil diff]" commands
to get a pop-up
window containing a complete side-by-side diff. (NB: The pop-up
window is run as a separate Tcl/Tk process, so you will need to
have Tcl/Tk installed on your machine for this to work. Visit
[http://www.activestate.com/activetcl] for a quick download of
Tcl/Tk if you do not already have it on your system.)
3. The "[/help/clean | fossil clean -x]" command is a great
alternative to "make clean". You can use "[/help/clean | fossil clean -f]"
as a slightly safer alternative if the "ignore-glob" setting is
not set. WARNING: make sure you did a "fossil add" for all source-files
you plan to commit, otherwise those files will be deleted without warning.
4. Use "[/help?cmd=all | fossil all changes]" to look for any uncommitted
edits in any of your Fossil projects. Use
"[/help?cmd=all | fossil all pull]" on your laptop
prior to going off network (for example, on a long plane ride)
to make sure you have all the latest content locally. Then run
"[/help/all|fossil all push]" when you get back online to upload
your changes.
5. To see an entire timeline, type "all" into the "Max:" entry box.
6. You can manually add a "c=CHECKIN" query parameter to the timeline
URL to get a snapshot of what was going on about the time of some
check-in. The "CHECKIN" can be
[./checkin_names.wiki | any valid check-in or version name], including
tags, branch names, and dates. For example, to see what was going
on in the Fossil repository on 2008-01-01, visit
[/timeline?c=2008-01-01].
7. Further to the previous two hints, there are lots of query parameters
that you can add to timeline pages. The available query parameters
are tersely documented [/help?cmd=/timeline | here].
8. You can run "[/help?cmd=xdiff | fossil xdiff --tk $file1 $file2]"
to get a Tk pop-up window with side-by-side diffs of two files, even if
neither of the two files is part of any Fossil repository. Note that
this command is "xdiff", not "diff". Change <nobr>--tk</nobr> to
<nobr>--by</nobr> to see the diff in your web browser.
9. On web pages showing the content of a file (for example
[/artifact/c7dd1de9f]) you can manually
add a query parameter of the form "ln=FROM,TO" to the URL that
will cause the range of lines indicated to be highlighted. This
is useful in pointing out a few lines of code using a hyperlink
in an email or text message. Example:
[/artifact/c7dd1de9f?ln=28,30].
Adding the "ln" query parameter without any argument simply turns
on line numbers. This feature only works right with files with
a mimetype of text/plain, of course.
10. When editing documentation to be checked in as managed files, you can
preview what the documentation will look like by using the special
"ckout" branch name in the "doc" URL while running "fossil ui".
See the [./embeddeddoc.wiki | embedded documentation] for details.
11. Use the "[/help?cmd=ui|fossil ui /]" command to bring up a menu of
all of your local Fossil repositories in your web browser.
12. If you have a bunch of Fossil repositories living on a remote machine
that you are able to access using ssh using a command like
"ssh login@remote", then you can bring up a user interface for all
those remote repositories using the command:
"[/help?cmd=ui|fossil ui login@remote:/]". This works by tunneling
all HTTP traffic through SSH to the remote machine.

[100]: https://en.wikipedia.org/wiki/Distributed_version_control [105]: /timeline?a=1970-01-01&n1=10 [110]: https://sqlite.org/crew.html [115]: https://sqlite.org/ Though Fossil was originally written specifically to support SQLite, it is now also used by countless other projects. The SQLite architect (drh) is still the top committer to Fossil, but there are also [many other contributors][120]. [120]: /reports?type=ci&view=byuser ## History The SQLite project started out using [CVS][300], as CVS was the most commonly used version control system in that era (circa 2000). CVS was an amazing version control system for its day in that it allowed multiple developers to be editing the same file at the same time. [300]: https://en.wikipedia.org/wiki/Concurrent_Versions_System Though innovative and much loved in its time, CVS was not without problems. Among those was a lack of visibility into the project history and the lack of integrated bug tracking. To address these deficiencies, the SQLite author developed the [CVSTrac][305] wrapper for CVS beginning in [2002][310]. [305]: http://cvstrac.org/ [310]: http://cvstrac.org/fossil/timeline?a=19700101&n1=10 CVSTrac greatly improved the usability of CVS and was adopted by other projects. CVSTrac also [inspired the design][315] of [Trac][320], which was a similar system that was (and is) far more widely used. [315]: https://trac.edgewall.org/wiki/TracHistory [320]: https://trac.edgewall.org/ Historians can see the influence of CVSTrac on the development of SQLite. [Early SQLite check-ins][325] that happened before CVSTrac often had a check-in comment that was just a "smiley". That was not an unreasonable check-in comment, as check-in comments were scarcely seen and of questionable utility in raw CVS. CVSTrac changed that, making check-in comments more visible and more useful. The SQLite developers reacted by creating [better check-in comments][330]. [325]: https://sqlite.org/src/timeline?a=19700101&n1=10 [330]: https://sqlite.org/src/timeline?c=20030101&n1=10&nd At about this same time, the [Monotone][335] system appeared. Monotone was one of the first distributed version control systems. As far as this author is aware, Monotone was the first VCS to make use of SHA1 to identify artifacts. Monotone stored its content in an SQLite database, which is what brought it to the attention of the SQLite architect. These design choices were a major source of inspiration for Fossil. [335]: https://www.monotone.ca/ Beginning around 2005, the need for a better version control system for SQLite began to become evident. The SQLite architect looked around for a suitable replacement. Monotone, Git, and Mercurial were all considered. But at that time, none of these supported sync over ordinary HTTP, none could be run from an inexpensive shell account on a leased server (this was before the widespread availability of affordable virtual private servers), and none of them supported anything resembling the wiki and ticket features of CVSTrac that had been found to be so useful. And so, the SQLite architect began writing his own DVCS. Early prototypes were done in [TCL][340]. As experiments proceeded, however, it was found that the low-level byte manipulates needed for things like delta compression and computing diffs were better implemented in plain old C. Experiments continued. Finally, a prototype capable of self-hosting was devised on [2007-07-16][345]. [340]: https://www.tcl.tk/ [345]: https://fossil-scm.org/fossil/timeline?c=200707211410&n1=10 The first project hosted by Fossil was Fossil itself. After a few months of development work, the code was considered stable enough to begin hosting the [SQLite documentation repository][350] which was split off from the main SQLite CVS repository on [2007-11-12][355]. After two years of development work on Fossil, the SQLite source code itself was transferred to Fossil on [2009-08-11][360].

# Hooks
Hooks are short scripts that Fossil runs at defined points of processing.
Administrators can use hooks to help enforce policy or connect Fossil to
a continuous integration (CI) system.
## Interim Documentation.
* This is a work-in-progress. The interface is in flux.
For the time being, the documentation is a list of
bullet points. We hope to transform this into a proper document
later, after things settle down.
* Contributions and suggestions to the hook system and/or the
documentation are welcomed.
## General Notes.
* Each hooks has a "type", a "sequence", and a "command". The command
is a shell command that runs at the appropriate time. The type
is currently one of "after-receive", "before-commit", "commit-msg",
or "disabled". The sequence is an arbitrary integer.
* There can be multiple hooks of the same type. When that is the
case, the hooks are run in order of ascending sequence.
* Use the "fossil hook" command to create, edit, and delete hooks.
* Use the "fossil hook test" command to test new hooks.
## Hook Scripts
* All scripts are expected to run relatively quickly. If a long-running
process is started by a hook, it should be run in the background so
that the original script can return.
* The "%F" sequence inside the script is translated into the
name of the fossil executable.
* The "%R" sequence in the script is translated into the name of
the repository.
* The "%A" sequence becomes the name of an auxiliary input file,
the meaning of which depends on the hook type. The auxiliary filename
might be an empty string. Take care to use appropriate quoting!
## Disabled Hooks
* Hooks with type "disabled" never run. They are a place-holder for
scripts that might be converted to some other hook-type later.
For example, the command "fossil hook edit --type disabled ID"
can be used to temporarily disable the hook named ID, and then
"fossil hook edit --type after-receive ID" can be used to reenable
it later.
## After-Receive Hooks
* The "after-receive" hook is run by [the backoffice](./backoffice.md)
whenever new artifacts are received into the repository. The artifacts
have already been committed and so there is nothing that the
after-receive hook can do to block them.
* The after-receive hooks are intended to be run on a server to start
up a background testing or CI process. But they can also be run
on the client side. The key point is that after-receive hooks are
invoked by backoffice, so backoffice must be running in order to
fire after-receive hooks.
* The exit code from the after-receive script is ignored.
* The standard input to the after-receive hook is a list of
new artifacts, one per line. The first token on each line is the
hash of the new artifact. After the hash is a human-readable text
description of what the artifact represents.
* Sometimes the same artifact can represent two or more things.
For example, the same artifact might represent two or more files
in the check-out (assuming the files hold identical content). In
that case, the text description that is input to the after-receive
hook only shows one of the possible uses for the artifact.
* If two or more pushes occur against a repository at about the same
time, then the set of artifacts added by both pushes might be
combined into a single after-receive callback.
* Fossil holds a write transaction on the repository while the
after-receive hook is running. If the script needs to access the
database, then the database will need to be in WAL mode so that
readers can co-exist with the writer. Or the script might just
launch a background process that waits until the hook script finishes
and the transaction commits before it tries to access the repository
database.
* A push might not deliver all of the artifacts for a checkin. If
Fossil knows that a /xfer HTTP request is incomplete, it will defer
running the after-receive push for 60 seconds, or until a complete
/xfer request is received. This helps to prevent after-receive hooks
from running when incomplete checkins exist in the repository, but
it does not provide hard guarantees, as there is no way to do that
in a distributed system.
* The list of artifacts delivered to standard input of the
after-receive hook will not contain more than 24-hours worth
of artifacts. If the backoffice has been shut down for a while
such that after-receive hooks have not been running, and more
than 24-hours of changes have accumulated since the last run
of an after-receive hook, then only the most recent 24-hours
is included in the input.
## Before-Commit Hooks
* Before-commit hooks run during the "fossil commit" command before
the user is prompted for the check-in comment. Fossil holds
a write-transaction on the repository when the before-commit
hook is running, so the repository needs to be in WAL mode if the
script needs to access the repository.
* The %A substitution is the name of a "commit description file" that
shows the details of the commit in progress. To see what a
"commit description file" looks like, set a before-commit hook
with a command of "cat %Q" and then run a sample commit with
the --dry-run option.
* If any before-commit hook returns a non-zero exit code, then
the commit is abandoned. All
before-commit hooks must exit(0) in order for the commit to
proceed.
* The --no-validate flag to the "fossil commit" command prevents any
before-commit hooks from running.
* The --trace flag to the "fossil commit" command shows each
before-commit hook as it is run.
* If a before-commit hook fails, it should print an error message
on standard output or standard error. Otherwise, the user won't
know what went wrong, because Fossil won't tell them.
* Nothing is written to standard input of the before-commit hook.
The information transmitted to the before-commit hook is contained
in the "%A" auxiliary file. The before-commit hook must open and
read that file if it wants access to the commit information.
## Commit-Msg Hooks
* Commit-msg hooks are not yet implemented.
* The commit-msg hooks run during "fossil commit" after the check-in
message has been entered by the user. The "%A" argument to the
commit-msg hook is the text of the commit message. The intent
of the commit-msg hook is to validate the text of the commit
message to (for example) check for typos or ensure that it
conforms to standards.
* If any commit-msg hook returns a non-zero exit code, then
the commit is abandoned. All
commit-msg hooks must exit(0) in order for the commit to
proceed.
* Commit-msg hooks are advisory only. Each developer is in total
control of the local repository and can easily bypass the hooks
to cause a non-conforming checkin to be committed.

"# Image Format vs Fossil Repository Size\n",
"\n",
"## Prerequisites\n",
"\n",
"This notebook was originally developed with standalone [JupyterLab] and Python 2 but was later moved to JupyterLab under [Anaconda] with Python 3. Backporting to Python 2 may require manual adjustment. Getting it running under stock JupyterLab or plain-old-Jupyter should be straightforward for one familiar with the tools. We will assume you're following in my footsteps, using Anaconda.\n",
"\n",
"One of the reasons we switched to Anaconda is that it comes with all but one of this notebook's prerequisites, that last remaining one of which you install so:\n",
"\n",
" $ pip install wand\n",
"\n",
"That should be done in a shell where \"`pip`\" is the version that came with Anaconda. Otherwise, the package will likely end up in some *other* Python package tree, which Anaconda's Python kernel may not be smart enough to find on its own.\n",
"\n",
"Note that you do *not* use `conda` for this: as of this writing, [Wand] is not available in a form that installs via `conda`.\n",
"\n",
"This notebook was written and tested on a macOS system where `/tmp` exists. Other platforms may require adjustments to the scripts below.\n",
"\n",
"[Anaconda]: https://www.anaconda.com/distribution/\n",
"[JupyterLab]: https://github.com/jupyterlab/\n",
"[Wand]: http://wand-py.org/\n",
"\n",
"\n",
"## Running\n",
"\n",
"The next cell generates the test repositories. This takes about 3 seconds to run on my machine. If you have to uncomment the \"`sleep`\" call in the inner loop, this will go up to about 45 seconds.\n",
"\n",
"The next cell produces the bar chart from the collected data, all but instantaneously.\n",
"\n",
"This split allows you to generate the expensive experimental data in a single pass, then play as many games as you like with the generated data.\n",
"\n",
"\n",
"## Discussion\n",
"\n",
"That is kept in [a separate document](image-format-vs-repo-size.md) so we can share that document with Fossil's Markdown renderer."

# Image Format vs Fossil Repo Size
## The Problem
Fossil has a [delta compression][dc] feature which removes redundant
information from a file relative to its parent on check-in.[^delta-prgs]
That delta is then [zlib][zl]-compressed before being stored
in the Fossil repository database file.
Storing pre-compressed data files in a Fossil repository defeats both of
these space-saving measures:
1. Binary data compression algorithms turn the file data into
pseudorandom noise.[^prn]
Typical data compression algorithms are not [hash functions][hf],
where the goal is that a change to each bit in the input has a
statistically even chance of changing every bit in the output, but
because they do approach that pathological condition, pre-compressed
data tends to defeat Fossil’s delta compression algorithm, there
being so little correlation between two different outputs from the
binary data compression algorithm.
2. An ideal lossless binary data compression algorithm cannot be
applied more than once to make the data even smaller, since random
noise is incompressible. The consequence for our purposes here is
that pre-compressed data doesn’t benefit from Fossil’s zlib
compression.
You might then ask, what does it matter if the space savings comes from
the application file format (e.g. JPEG, DOCX, Zip, etc.) or from Fossil
itself? It really doesn’t, as far as point 2 above goes, but point 1
causes the Fossil repository to balloon out of proportion to the size of
the input data change on each checkin. This article will illustrate that
problem, quantify it, and give a solution to it.

## <a id="formats"></a>Affected File Formats
In this article’s core experiment, we use 2D image file formats, but
this article’s advice also applies to many other file types. For just a
few examples out of what must be thousands:
* **Microsoft Office**: The [OOXML document format][oox] used from
Office 2003 onward (`.docx`, `.xlsx`, `.pptx`, etc.) are Zip files
containing an XML document file and several collateral files.
* **Libre Office**: For the purposes of this article, its
[OpenDocument Format][odf] is designed the same basic way as OOXML.
* **Java**: A Java [`.jar` file][jcl] is a Zip file containing JVM
`.class` files, manifest files, and more.
* **Windows Installer:** An [`*.msi` file][wi] is a proprietary
database format that contains, among other things, [Microsoft
Cabinet][cab]-compressed files, which in turn may hold Windows
executables, which [may themselves be compressed][exc].
* **SVG, PDF, TIFF, etc.**: Many file formats are available in both
compressed and uncompressed forms. You should use the uncompressed
form with Fossil wherever practical, as we will show below.

## <a id="demo"></a>Demonstration
The companion `image-format-vs-repo-size.ipynb` file ([download][nbd],
[preview][nbp]) is a [JupyterLab][jl] notebook implementing the following
experiment:
1. Create a new minimum-size Fossil repository. Save this initial size.
2. Use [ImageMagick][im] via [Wand][wp] to generate a JPEG file of a
particular size — currently 256 px² — filled with Gaussian noise to
make data compression more difficult than with a solid-color image.
3. Check that image into the new Fossil repo, and remember that size.
4. Change a random pixel in the image to a random RGB value, save that
image, check it in, and remember the new Fossil repo size.
5. Iterate on step 4 some number of times — currently 10 — and remember
the Fossil repo size at each step.
6. Repeat the above steps for BMP, PNG, and TIFF.[^tiff-cmp]
7. Create a bar chart showing how the Fossil repository size changes
with each checkin.
We chose to use JupyterLab for this because it makes it easy for you to
modify the notebook to try different things. Want to see how the
results change with a different image size? Easy, change the `size`
value in the second cell of the notebook. Want to try more image
formats? You can put anything ImageMagick can recognize into the
`formats` list. Want to find the break-even point for images like those
in your own repository? Easily done with a small amount of code.

## <a id="results"></a>Results
Running the notebook gives a bar chart something like[^variance] this:
There are a few key things we want to draw your attention to in that
chart:
* BMP and uncompressed TIFF are nearly identical in size for all
checkins, and the repository growth rate is negligible past the
first commit.[^size-jump] We owe this economy to Fossil’s delta compression
feature: it is encoding each of those single-pixel changes in a very
small amount of repository space.
* The JPEG and PNG bars increase by large amounts on most checkins
even though each checkin *also* encodes only a *single-pixel change*.
* The size of the first checkin in the BMP and TIFF cases is roughly
the same as that for the PNG case, because both PNG and Fossil use
the zlib binary data compression algorithm. This shows that for
repos where the image files are committed only once, there is
virtually no penalty to using BMP or TIFF over PNG. The file sizes
likely differ only because of differences in zlib settings between
the cases.
* Because JPEG’s lossy nature allows it to start smaller and have
smaller size increases than PNG, the crossover point with
BMP/TIFF isn’t until 7-9 checkins in typical runs of this [Monte
Carlo experiment][mce]. Given a choice among these four file
formats and a willingness to use lossy image compression, a rational
tradeoff is to choose JPEG for repositories where each image will
change fewer than that number of times.

## <a id="makefile"></a>Automated Recompression
Since programs that produce and consume binary-compressed data files
often make it either difficult or impossible to work with the
uncompressed form, we want an automated method for producing the
uncompressed form to make Fossil happy while still having the compressed
form to keep our content creation applications happy. This `Makefile`
should[^makefile] do that for BMP, PNG, SVG, and XLSX files:
.SUFFIXES: .bmp .png .svg .svgz
.svgz.svg:
gzip -dc < $< > $@
.svg.svgz:
gzip -9c < $< > $@
.bmp.png:
convert -quality 95 $< $@
.png.bmp:
convert $< $@
SS_FILES := $(wildcard spreadsheet/*)
all: $(SS_FILES) illus.svg image.bmp doc-big.pdf
reconstitute: illus.svgz image.png
( cd spreadsheet ; zip -9 ../spreadsheet.xlsx) * )
qpdf doc-big.pdf doc-small.pdf
$(SS_FILES): spreadsheet.xlsx
unzip $@ -d $<
doc-big.pdf: doc-small.pdf
qpdf --stream-data=uncompress $@ $<
This `Makefile` allows you to treat the compressed version as the
process input, but to actually check in only the changes against the
uncompressed version by typing “`make`†before “`fossil ci`â€. This is
not actually an extra step in practice, since if you’ve got a
`Makefile`-based project, you should be building — and testing — it
before checking each change in anyway!
Because this technique is based on dependency rules, only the necessary
files are generated on each `make` command.
You only have to run “`make reconstitute`†*once* after opening a fresh
Fossil checkout to produce those compressed sources. After that, you
work with the compressed files in your content creation programs. Your
build system might include some kind of bootstrapping or
auto-configuration step that you could attach this to, so that it
doesn’t need to be run by hand.
This `Makefile` illustrates two primary strategies:
### Input and Output File Formats Differ by Extension
In the case of SVG and the bitmap image formats, the file name extension
differs between the cases, so we can use `make` suffix rules to get the
behavior we want. The top half of the `Makefile` just tells `make` how
to map from `*.svg` to `*.svgz` and vice versa, and the same for `*.bmp`
to/from `*.png`.
### Input and Output Use the Same Extension
We don’t have that luxury for Excel and PDF files, each for a different
reason:
* **Excel:** Excel has no way to work with the unpacked Zip file
contents at all, so we have to unpack it into a subdirectory, which
is what we check into Fossil. On making a fresh Fossil checkout, we
have to pack that subdirectory’s contents back up into an `*.xlsx`
file with “`make reconstitute`†so we can edit it with Excel again.
* **PDF:** All PDF readers can display an uncompressed PDF file, but
many PDF-*producing* programs have no option for uncompressed
output. Since the file name extension is the same either way, we
treat the compressed PDF as the source to the process, yielding an
automatically-uncompressed PDF for the benefit of Fossil. Unlike
with the Excel case, there is no simple “file base name to directory
name†mapping, so we just created the `-big` to `-small` name scheme
here.
[^delta-prgs]:
This problem is not Fossil-specific. Several other programs also do
delta compression, so they’ll also be affected by this problem:
[rsync][rs], [Unison][us], [Git][git], etc. You should take this
article’s advice when using all such programs, not just Fossil.
When using file copying and synchronization programs *without* delta
compression, on the other hand, it’s best to use the most
highly-compressed file format you can tolerate, since they copy the
whole file any time any bit of it changes.
[^prn]:
In fact, a good way to gauge the effectiveness of a given
compression scheme is to run its output through the same sort of
tests we use to gauge how “random†a given [PRNG][prng] is. Another
way to look at it is that if there is a discernible pattern in the
output of a compression scheme, that constitutes *information* (in
[the technical sense of that word][ith]) that could be further
compressed.
[^tiff-cmp]:
We're using *uncompressed* TIFF here, not [LZW][lzw]- or
Zip-compressed TIFF, either of which would give similar results to
PNG, which is always zlib-compressed.
[^variance]:
The raw data changes somewhat from one run to the next due to the
use of random noise in the image to make the zlib/PNG compression
more difficult, and the random pixel changes. Those test design
choices make this a [Monte Carlo experiment][mce]. We’ve found that
the overall character of the results doesn’t change from one run to
the next.
[^size-jump]:
It’s not clear to me why there is a one-time jump in size for BMP
and TIFF past the first commit. I suspect it is due to the SQLite
indices being initialized for the first time.
Page size inflation might have something to do with it as well,
though we tried to control that by rebuilding the initial DB with a
minimal page size. If you re-run the program often enough, you will
sometimes see the BMP or TIFF bar jump higher than the other, again
likely due to one of the repos crossing a page boundary.
Another curious artifact in the data is that the BMP is slightly
larger than for the TIFF. This goes against expectation because a
low-tech format like BMP should have a small edge in this test
because TIFF metadata includes the option for multiple timestamps,
UUIDs, etc., which bloat the checkin size by creating many small
deltas.
[^makefile]:
The `Makefile` above is not battle-tested. Please report bugs and
needed extensions [on the forum][for].

</div>
Fossil is a simple, high-reliability, distributed
[https://en.wikipedia.org/wiki/Software_configuration_management | SCM]
system with these advanced features:
1. <b>Project Management</b> —
In addition to doing [./concepts.wiki | distributed version control]
like Git and Mercurial,
Fossil also supports [./bugtheory.wiki | bug tracking],
[./wikitheory.wiki | wiki], [./forum.wiki | forum],
[./alerts.md|email alerts], [./chat.md | chat], and
[./event.wiki | technotes].
2. <b>Built-in Web Interface</b> —
Fossil has a built-in, [/skins | themeable], [./serverext.wiki | extensible],
and intuitive [./webui.wiki | web interface]
with a rich variety of information pages
([./webpage-ex.md|examples]) promoting situational awareness.
<br><br>
This entire website is just a running instance of Fossil.
The pages you see here are all [./wikitheory.wiki | wiki] or
[./embeddeddoc.wiki | embedded documentation] or (in the case of
the [/uv/download.html|download] page)
[./unvers.wiki | unversioned files].
When you clone Fossil from one of its
[./selfhost.wiki | self-hosting repositories],
you get more than just source code — you get this entire website.
3. <b>All-in-one</b> —
Fossil is a single self-contained, stand-alone executable.
To install, simply download a
[/uv/download.html | precompiled binary]
for Linux, Mac, or Windows and put it on your $PATH.
[./build.wiki | Easy-to-compile source code] is also available.
4. <b>Self-host Friendly</b> — Stand up a project website
in minutes using [./server/ | a variety of techniques].
Fossil is CPU and memory efficient. Most projects can be
hosted comfortably on a $5/month VPS or a Raspberry Pi.
You can also set up an automatic
[./mirrortogithub.md | GitHub mirror].
5. <b>Simple Networking</b> —
Fossil uses ordinary HTTPS (or SSH if you prefer)
for network communications, so it works fine from behind
firewalls and [./quickstart.wiki#proxy|proxies].
The protocol is
[./stats.wiki | bandwidth efficient] to the point that Fossil can be
used comfortably over dial-up, weak 3G, or airliner Wifi.
6. <b>Autosync</b> —
Fossil supports [./concepts.wiki#workflow | "autosync" mode]
which helps to keep projects moving
forward by reducing the amount of needless
[./branching.wiki | forking and merging] often
associated with distributed projects.
7. <b>Robust & Reliable</b> —
Fossil stores content using an [./fileformat.wiki | enduring file format]
in an SQLite database so that transactions are
atomic even if interrupted by a power loss or system crash.
Automatic [./selfcheck.wiki | self-checks] verify that all aspects of
the repository are consistent prior to each commit.
8. <b>Free and Open-Source</b> — [../COPYRIGHT-BSD2.txt|2-clause BSD license].

<title>Import And Export</title>
Fossil has the ability to import and export repositories from and to
[http://git-scm.com/ | Git]. And since most other version control
systems will also import/export from Git, that means that you can
import/export a Fossil repository to most version control systems using
Git as an intermediary.
<h2>Git → Fossil</h2>
To import a Git repository into Fossil, say something like:
<pre>
cd git-repo
git fast-export --all | fossil import --git new-repo.fossil
</pre>
The 3rd argument to the "fossil import"
command is the name of a new Fossil repository that is created to hold the Git
content.
The --git option is not actually required. The git-fast-export file format
is currently the only VCS interchange format that Fossil understands. But
future versions of Fossil might be enhanced to understand other VCS
interchange formats, and so for compatibility, use of the
--git option is recommended.
<a id="fx_git"></a>
Note that in new imports, Fossil defaults to using the email component of the
Git <em>committer</em> (or <em>author</em> if <code>--use-author</code> is
passed) to attribute check-ins in the imported repository. Alternatively, the
[/help?cmd=import | <code>--attribute</code>] option can be passed to have all
commits by a given committer attributed to a desired username. This will create
and populate the new <code>fx_git</code> table in the repository database to
maintain a record of correspondent usernames and email addresses that can be
used in subsequent exports or incremental imports.
<h3>Converting Repositories on Windows</h3>
The above commands work best on proper POSIX systems like Linux, macOS,
and the BSDs, where everything <tt>git</tt> sends is consumed by
<tt>fossil</tt> as soon as it can manage, with both programs working
concurrently.
For some reason, the current version of PowerShell included with Windows
chokes on the conversion when the in-flight repository size exceeds
available memory. We do not know why it buffers the entire stream
emitted by "<tt>git fast-export</tt>" before sending it along to Fossil,
but we've seen the problem recur on multiple machines.
While one workaround is to fall back to <tt>cmd.exe</tt> — which doesn't
seem to be affected by this problem — we instead recommend using
Microsoft's own [https://learn.microsoft.com/en-us/windows/wsl/ | Windows
Subsystem for Linux] or either of the two popular "Git for Windows"
distributions based on MSYS2. They handle pipes the POSIX way, avoiding
any dependency on the amount of data involved.
<h2>Fossil → Git</h2>
To convert a Fossil repository into a Git repository, run commands like
this:
<pre>
git init new-repo
cd new-repo
fossil export --git ../repo.fossil | git fast-import
</pre>
In other words, create a new Git repository, then pipe the output from the
"fossil export --git" command into the "git fast-import" command.
Note that the "fossil export --git" command only exports the versioned files.
Tickets and wiki and events are not exported, since Git does not understand
those concepts.
As with the "import" command, the --git option is not required
since the git-fast-export file format is currently the only VCS interchange
format that Fossil will generate. However,
future versions of Fossil might add the ability to generate other
VCS interchange formats, and so for compatibility, the use of the --git
option is recommended.
<h2>Mirror A Fossil Repository In Git</h2>
Fossil version 2.9 and later supports a simple mechanism for
doing a Git or
[./mirrortogithub.md|GitHub mirror of a Fossil repository].
See that separate document for details. Fossil is self-hosting,
but a [https://github.com/drhsqlite/fossil-mirror|GitHub mirror of Fossil]
is available as a proof-of-concept.
<h2>Bidirectional Synchronization</h2>
Fossil also has the ability to synchronize with a Git repository via repeated
imports and/or exports. To do this, it uses marks files to store a record of
artifacts which are known by both Git and Fossil to exist at a given point in
time.
To illustrate, consider the example of a remote Fossil repository that a
user wants to import into a local Git repository. First, the user would clone
the remote repository and import it into a new Git repository:
<pre>
fossil clone /path/to/remote/repo.fossil repo.fossil
mkdir repo
cd repo
fossil open ../repo.fossil
mkdir ../repo.git
cd ../repo.git
git init .
fossil export --git --export-marks ../repo/fossil.marks \
../repo.fossil | git fast-import \
--export-marks=../repo/git.marks
</pre>
Once the import has completed, the user would need to <tt>git checkout
trunk</tt>. At any point after this, new changes can be imported from the
remote Fossil repository:
<pre>
cd ../repo
fossil pull
cd ../repo.git
fossil export --git --import-marks ../repo/fossil.marks \
--export-marks ../repo/fossil.marks \
../repo.fossil | git fast-import \
--import-marks=../repo/git.marks \
--export-marks=../repo/git.marks
</pre>
Changes in the Git repository can be exported to the Fossil repository and then
pushed to the remote:
<pre>
git fast-export --import-marks=../repo/git.marks \
--export-marks=../repo/git.marks --all | fossil import --git \
--incremental --import-marks ../repo/fossil.marks \
--export-marks ../repo/fossil.marks ../repo.fossil
cd ../repo
fossil push
</pre>

# Interwiki Links
Interwiki links are a short-hand notation for links that target
external wikis or websites. For example, the following two
hyperlinks mean the same thing (assuming an appropriate [intermap](#intermap)
configuration):
* [](wikipedia:MediaWiki#Interwiki_links)
* [](https://en.wikipedia.org/wiki/MediaWiki#Interwiki_links)
Another example: The Fossil Forum is hosted in a separate repository
from the Fossil source code. This page is part of the
source code repository. Interwiki links can be used to more easily
refer to the forum repository:
* [](forum:d5508c3bf44c6393df09c)
* [](https://fossil-scm.org/forum/info/d5508c3bf44c6393df09c)
## Advantages Over Full URL Targets
* Interwiki links are easier to write. There is less typing,
and fewer opportunities to make mistakes.
* Interwiki links are easier to read. With well-chosen
intermap tags, the links are easier to understand.
* Interwiki links continue to work after a domain change on the
target. If the target of a link moves to a different domain,
an interwiki link will continue to work, if the intermap is adjusted,
but a hard-coded link will be permanently broken.
* Interwiki links allow clones to use a different target domain from the
original repository.
## Details
Fossil supports interwiki links in both the
[Fossil Wiki](/wiki_rules) and [Markdown](/md_rules) markup
styles. An interwiki link consists of a tag followed by a colon
and the link target:
> <i>Tag</i><b>:</b><i>PageName</i>
The Tag must consist of ASCII alphanumeric characters only - no
punctuation or whitespace or characters greater than U+007A.
The PageName is the link notation on the target wiki.
Three different classes of PageNames are recognized by Fossil:
1. <b>Path Links</b> → the PageName begins with the "/" character
or is an empty string.
2. <b>Hash Links</b> → the PageName is a hexadecimal number with
at least four digits.
3. <b>Wiki Links</b> → A PageName that is not a Path or Hash.
The Intermap defines a base URL for each Tag. Path links are appended
directly to the URL contained in the Intermap. The Intermap can define
additional text to put in between the base URL and the PageName for
Hash and Wiki links, respectively.
<a id="intermap"></a>
## Intermap
The intermap defines a mapping from interwiki Tags to full URLs. The
Intermap can be viewed and managed using the [fossil interwiki][iwiki]
command or the [/intermap][imap] webpage.
[iwiki]: /help?cmd=interwiki
[imap]: /intermap
The current intermap for a server is seen on the [/intermap][imap] page
(which is read-only for non-Setup users) and at the bottom of the built-in
[Fossil Wiki rules](/wiki_rules) and [Markdown rules](/md_rules)
documentation pages.
Each intermap entry stores, at a minimum, the base URL for the remote
wiki. The intermap entry might also store additional path text that
is used for Hash and Wiki links. If only the base URL is provided,
then the intermap will only allow Path style interwiki links. The
Hash and Wiki style interwiki links are only allowed if the necessary
extensions are provided in the intermap.
## Disadvantages and Limitations
* Configuration is required. The intermap must be set up correctly
before interwiki links will work. This contrasts with ordinary
links that just work without any configuration. Cloning a repository
copies the intermap, but normal syncs do not keep the intermap in
sync. Use the "[fossil config pull interwiki][fcfg]" command to
synchronize the intermap.
* The is no backlink tracking. For ordinary intrawiki links, Fossil keeps
track of both the source and target, and when displaying targets it
commonly shows links to that target. For example, if you mention a
check-in as part of a comment of another check-in, that new check-in
shows up in the "References" section of the target check-in.
([example](31af805348690958). In other words, Fossil tracks not just
"_source→target_", but it also tracks "_target→source_".
But backtracking does not work for interwiki links, since the Fossil
running on the target has no way of scanning the source text and
hence has no way of knowing that it is a target of a link from the source.
[fcfg]: /help?cmd=config
## Intermap Storage Details
The intermap is stored in the CONFIG table of the repository database,
in entries with names of the form "<tt>interwiki:</tt><i>Tag</i>". The
value for each such entry is a JSON string that defines the base URL
and extensions for Hash and Wiki links.

# Use of JavaScript in Fossil
## Philosophy & Policy
The Fossil development project’s policy is to use JavaScript where it
helps make its web UI better, but to offer graceful fallbacks wherever
practical. The intent is that the UI be usable with JavaScript
entirely disabled. In almost all places where Fossil uses JavaScript,
it is an enhancement to provided functionality, and there is always
another way to accomplish a given end without using JavaScript.
This is not to say that Fossil’s fall-backs for such cases are always as
elegant and functional as a no-JS purist might wish. That is simply
because [the vast majority of web users leave JavaScript unconditionally
enabled](#stats), and of the small minority of those that do not, a
large chunk use some kind of [conditional blocking](#block) instead,
rather than disable JavaScript entirely.
Fossil’s active developers do not deviate from that
norm enough that we have many no-JS purists among us, so the no-JS case
doesn’t get as much attention as some might want. We do [accept code
contributions][cg], and we are philosophically in favor of graceful
fall-backs, so you are welcome to appoint yourself the position of no-JS
czar for the Fossil project!
Evil is in actions, not in objects: we do not believe JavaScript *can*
be evil. It is an active technology, but the actions that matter here
are those of writing the code and checking it into the Fossil project
repository. None of the JavaScript code in Fossil is evil, a fact we
enforce by being careful about who we give check-in rights on the
repository to and by policing what code does get contributed. The Fossil
project does not accept non-trivial outside contributions.
We think it’s better to ask not whether Fossil requires JavaScript but
whether Fossil uses JavaScript *well*, so that [you can decide](#block)
to block or allow Fossil’s use of JavaScript.
The Fossil developers want to see the project thrive, and we achieve
that best by making it usable and friendly to a wider audience than the
minority of static web app purists. Modern users generally expect a
smoother experience than was available with 1990s style HTTP
POST-and-response `<form>` based interaction. We also increase the set
of potential Fossil developers if we do not restrict them to such
antiquated methods.
JavaScript is not perfect, but it's what we have, so we will use it
where we find it advantageous.
[cg]: ./contribute.wiki
## <a id="debate"></a>Arguments Against JavaScript & Our Rebuttals
There are many common arguments against the use of JavaScript. Rather than
rehash these same arguments on the [forum][ffor], we distill the common
ones we’ve heard before and give our stock answers to them here:
1. “**It increases the size of the page download.**â€
The heaviest such pages served by Fossil only have about 15Â kB of
compressed JavaScript. (You have to go out of your way to get Fossil
to serve uncompressed pages.) This is negligible, even over very
slow data connections. If you are still somehow on a 56Â kbit/sec
analog telephone modem, this extra script code would download in
a few seconds.
Most JavaScript-based Fossil pages use less code than that.
Atop that, Fossil sends HTTP headers to the browser that allow it
to perform aggressive caching so that typical page loads will skip
re-loading this content on subsequent loads. These features are
currently optional: you must either set the new
[`fossil server --jsmode bundle` option][fsrv] or the corresponding
`jsmode` control line
in your [`fossil cgi`][fcgi] script when setting up your
[Fossil server][fshome]. That done, Fossil’s JavaScript files will
load almost instantly from the browser’s cache after the initial
page load, rather than be re-transferred over the network.
Between the improved caching and the fact that it’s quicker to
transfer a partial Ajax page load than reload the entire page, the
aggregate cost of such pages is typically *lower* than the older
methods based on HTTP POST with a full server round-trip. You can
expect to recover the cost of the initial page load in 1-2
round-trips. If we were to double the amount of JavaScript code in
Fossil, the payoff time would increase to 2-4 round-trips.
2. “**JavaScript is slow.**â€
It *was*, before September 2008. Google's introduction of [their V8
JavaScript engine][v8] taught the world that JavaScript need not be
slow. This competitive pressure caused the other common JavaScript
interpreters to either improve or be replaced by one of the engines
that did improve to approach V8’s speed.
Nowadays JavaScript is, as a rule, astoundingly fast. As the world
continues to move more and more to web-based applications and
services, JavaScript engine developers have ample motivation to keep
their engines fast and competitive.
Ajax partial page updates are faster than
the no-JS alternative, a full HTTP POST round-trip to submit new
data to the remote server, retrieve an entire new HTML document,
and re-render the whole thing client-side.
3. <a id="3pjs"></a>“**Third-party JavaScript cannot be trusted.**â€
Fossil does not use any third-party JavaScript libraries, not even
very common ones like jQuery. Every bit of JavaScript served by the
stock version of Fossil was written specifically for the Fossil
project and is stored [in its code repository][fsrc].
Therefore, if you want to hack on the JavaScript code served by
Fossil and mechanisms like [skin editing][cskin] don’t suffice for your
purposes, you can hack on the JavaScript in your local instance
directly, just as you can hack on its C, SQL, and Tcl code. Fossil
is free and open source software, under [a single license][2cbsd].
4. <a id="snoop"></a>“**JavaScript and cookies are used to snoop on web users.**â€
There is no tracking or other snooping technology in Fossil other than
that necessary for basic security, such as IP address logging on
check-ins. (This is in part why we have no [comprehensive user
statistics](#stats)!)
Fossil attempts to set two cookies on all web clients: a login session
cookie and a display preferences cookie. These cookies are restricted to
the Fossil instance, so even this limited data cannot leak between
Fossil instances or into other web sites.
5. “**JavaScript is fundamentally insecure.**â€
JavaScript is certainly sometimes used for nefarious ends, but if we
wish to have more features in Fossil, the alternative is to add more
code to the Fossil binary, [most likely in C][fslpl], a language
implicated in [over 4× more security vulnerabilities][whmsl].
Therefore, does it not make sense to place approximately four times
as much trust in Fossil’s JavaScript code as in its C code?
The question is not whether JavaScript is itself evil, it is whether
its *authors* are evil. *Every byte* of JavaScript code used within
the Fossil UI is:
* ...written by the Fossil developers, vetted by their peers.
* ...[open source][flic] and [available][fsrc] to be inspected,
audited, and changed by its users.
* ...compiled directly into the `fossil` binary in a
non-obfuscated form during the build process, so there are no
third-party servers delivering mysterious, obfuscated JavaScript
code blobs to the user.
Local administrators can [modify the repository’s skin][cskin] to
inject additional JavaScript code into pages served by their Fossil
server. A typical case is to add a syntax highlighter like
[Prism.js][pjs] or [highlightjs][hljs] to the local repository. At
that point, your trust concern is not with Fossil’s use of
JavaScript, but with your trust in that repository’s administrator.
Fossil's [default content security policy][dcsp] (CSP)
prohibits execution of JavaScript code which is delivered from
anywhere but the Fossil server which delivers the page. A local
administrator can change this CSP, but again this comes down to a
matter of trust with the administrator, not with Fossil itself.
6. “**Cross-browser compatibility is poor.**â€
It most certainly was in the first decade or so of JavaScript’s
lifetime, resulting in the creation of powerful libraries like
jQuery to patch over the incompatibilities. Over time, the need for
such libraries has dropped as browser vendors have fixed the
incompatibilities. Cross-browser JavaScript compatibility issues
which affect web developers are, by and large, a thing of the past.
7. “**Fossil UI works fine today without JavaScript. Why break it?**â€
While this is true today, and we have no philosophical objection to
it remaining true, we do not intend to limit ourselves to only those
features that can be created without JavaScript. The mere
availability of alternatives is not a good justification for holding
back on notable improvements when they're within easy reach.
The no-JS case is a [minority position](#stats), so those that want
Fossil to have no-JS alternatives and graceful fallbacks will need
to get involved with the development if they want this state of
affairs to continue.
8. <a id="stats"></a>“**A large number of users run without JavaScript enabled.**â€
That’s not what web audience measurements say:
* [What percentage of browsers with javascript disabled?][s1]
* [How many people are missing out on JavaScript enhancement?][s2]
* [Just how many web users really disable cookies or JavaScript?][s3]
Our sense of this data is that only about 0.2% of web users had
JavaScript disabled while participating in these studies.
The Fossil user community is not typical of the wider web, but if we
were able to comprehensively survey our users, we’d expect to find
an interesting dichotomy. Because Fossil is targeted at software
developers, who in turn are more likely to be power-users, we’d
expect to find Fossil users to be more in favor of some amount of
JavaScript blocking than the average web user. Yet, we’d also expect
to find that our user base has a disproportionately high number who
run [powerful conditional blocking plugins](#block) in their
browsers, rather than block JavaScript entirely. We suspect that
between these two forces, the number of no-JS purists among Fossil’s
user base is still a tiny minority.
9. <a id="block"></a>“**I block JavaScript entirely in my browser. That breaks Fossil.**â€
First, see our philosophy statements above. Briefly, we intend that
there always be some other way to get any given result without using
JavaScript, developer interest willing.
But second, it doesn’t have to be all-or-nothing. We recommend that
those interested in blocking problematic uses of JavaScript use
tools like [NoScript][ns] or [uBlock Origin][ubo] to *selectively*
block JavaScript so the rest of the web can use the technology
productively, as it was intended.
There are doubtless other useful tools of this sort. We recommend
these two only from our limited experience, not out of any wish to
exclude other tools.
The primary difference between these two for our purposes is that
NoScript lets you select scripts to run on a page on a case-by-case
basis, whereas uBlock Origin delegates those choices to a group of
motivated volunteers who maintain allow/block lists to control all
of this; you can then override UBO’s stock rules as needed.
10. “**My browser doesn’t even *have* a JavaScript interpreter.**â€
The Fossil open source project has no full-time developers, and only
a few of these part-timers are responsible for the bulk of the code
in Fossil. If you want Fossil to support such niche use cases, then
you will have to [get involved with its development][cg]: it’s
*your* uncommon itch.
11. <a id="compat"></a>“**Fossil’s JavaScript code isn’t compatible with my browser.**â€
The Fossil project’s developers aim to remain compatible with
the largest portions of the client-side browser base. We use only
standards-defined JavaScript features which are known to work in the
overwhelmingly vast majority of browsers going back approximately 5
years, at minimum, as documented by [Can I Use...?][ciu] We avoid use of
features added to the language more recently or those which are still in
flux in standards committees.
We set this threshold based on the amount of time it typically takes for
new standards to propagate through the installed base.
As of this writing, this means we are only using features defined in
[ECMAScript 2015][es2015], colloquially called “JavaScript 6.†That
is a sufficiently rich standard that it more than suffices for our
purposes, and it is [widely deployed][es6dep]. The biggest single
outlier remaining is MSIE 11, and [even Microsoft is moving their
own products off of it][ie11x].

## <a id="uses"></a>Places Where Fossil’s Web UI Uses JavaScript
This section documents the areas where Fossil currently uses JavaScript
and what it does when these uses are blocked. It also gives common
workarounds where necessary.
### <a id="timeline"></a>Timeline Graph
Fossil’s [web timeline][wt] uses JavaScript to render the graph
connecting the visible check-ins to each other, so you can visualize
parent/child relationships, merge actions, etc. We’re not sure it’s even
possible to render this in static HTML, even with the aid of SVG, due to
the vagaries of web layout among browser engines, screen sizes, etc.
Fossil also uses JavaScript to handle clicks on the graph nodes to allow
diffs between versions, to display tooltips showing local context, etc.
_Graceful Fallback:_ When JavaScript is disabled, this column of the
timeline simply collapses to zero width. All of the information you can
get from the timeline can be retrieved from Fossil in other ways not
using JavaScript: the “`fossil timeline`†command, the “`fossil info`â€
command, by clicking around within the web UI, etc.
_Potential Workaround:_ The timeline could be enhanced with `<noscript>`
tags that replace the graph with a column of checkboxes that control
what a series of form submit buttons do when clicked, replicating the
current JavaScript-based features of the graph using client-server round-trips.
For example, you could click two of those checkboxes and then a button
labeled “Diff Selected†to replicate the current “click two nodes to
diff them†feature.
[wt]: https://fossil-scm.org/home/timeline
### <a id="wedit"></a>The New Wiki Editor
The [new wiki editor][fwt] has many new features, a
few of which are impossible to get without use of JavaScript.
First, it allows in-browser previews without losing client-side editor
state, such as where your cursor is. With the old editor, you had to
re-locate the place you were last editing on each preview, which would
reduce the incentive to use the preview function. In the new wiki
editor, you just click the Preview tab to see how Fossil interprets your
markup, then click back to the Editor tab to resume work with the prior
context undisturbed.
Second, it continually saves your document state in client-side storage
in the background while you’re editing it so that if the browser closes
without saving the changes back to the Fossil repository, you can resume
editing from the stored copy without losing work. This feature is not so
much about saving you from crashes of various sorts, since computers are
so much more reliable these days. It is far more likely to save you from
the features of mobile OSes like Android and iOS which aggressively shut
down and restart apps to save on RAM. That OS design philosophy assumes
that there is a way for the app to restore its prior state from
persistent media when it’s restarted, giving the illusion that it was
never shut down in the first place. This feature of Fossil’s new wiki
editor provides that.
With this change, we lost the old WYSIWYG wiki editor, available since
Fossil version 1.24. It hadn’t been maintained for years, it was
disabled by default, and no one stepped up to defend its existence when
this new editor was created, replacing it. If someone rescues that
feature, merging it in with the new editor, it will doubtless require
JavaScript in order to react to editor button clicks like the “**B**â€
button, meaning “make \[selected\] text boldface.†There is no standard
WYSIWYG editor component in browsers, doubtless because it’s relatively
straightforward to create one using JavaScript.
_Graceful Fallback:_ Fossil’s lack of
a script-free wiki editor mode is not from lack of
desire, but because the person who wrote the new wiki editor didn’t
want to maintain three different editors. (New Ajaxy editor, old
script-free HTML form based editor, and the old WYSIWYG JavaScript-based
editor.) If someone wants to implement a `<noscript>` alternative to the
new wiki editor, we will likely accept that [contribution][cg] as long
as it doesn’t interfere with the new editor. (The same goes for adding
a WYSIWYG mode to the new Ajaxy wiki editor.)
_Workaround:_ You don’t have to use the browser-based wiki editor to
maintain your repository’s wiki at all. Fossil’s [`wiki` command][fwc]
lets you manipulate wiki documents from the command line. For example,
consider this Vi based workflow:
```shell
$ vi 'My Article.wiki' # begin work on new article
...write, write, write...
:w # save changes to disk copy
:!fossil wiki create 'My Article' '%' # current file (%) to new article
...write, write, write some more...
:w # save again
:!fossil wiki commit 'My Article' '%' # update article from disk
:q # done writing for today
....days later...
$ vi # work sans named file today
:r !fossil wiki export 'My Article' - # pull article text into vi buffer
...write, write, write yet more...
:w !fossil wiki commit - # vi buffer updates article
```
Extending this concept to other text editors is an exercise left to the
reader.
[fwc]: /help?cmd=wiki
[fwt]: ./wikitheory.wiki
### <a id="fedit"></a>The File Editor
Fossil’s [optional file editor feature][fedit] works
much like [the new wiki editor](#wedit), only on files committed to the
repository.
The original designed purpose for this feature is to allow [embedded
documentation][edoc] to be interactively edited in the same way that
wiki articles can be. (Indeed, the associated `fileedit-glob` feature
allows you to restrict the editor to working *only* on files that can be
treated as embedded documentation.) This feature operates in much the
same way as the new wiki editor, so most of what we said above applies.
_Workaround:_ This feature is an alternative to Fossil’s traditional
mode of file management: clone the repository, open it somewhere, edit a
file locally, and commit the changes.
_Graceful Fallback:_ There is no technical reason why someone could not
write a `<noscript>` wrapped alternative to the current JavaScript based
`/fileedit` implementation. It would have all of the same downsides as
the old wiki editor: the users would lose their place on each save, they
would have no local backup if something crashes, etc. Still, we are
likely to accept such a [contribution][cg] as long as it doesn’t
interfere with the new editor.
[edoc]: /doc/trunk/www/embeddeddoc.wiki
[fedit]: /doc/trunk/www/fileedit-page.md
### <a id="ln"></a>Line Numbering
When viewing source files, Fossil offers to show line numbers in some
cases. ([Example][mainc].) Toggling them on and off is currently handled
in JavaScript, rather than forcing a page-reload via a button click.
_Workaround:_ Manually edit the URL to give the “`ln`†query parameter
per [the `/file` docs](/help?cmd=/file).
_Potential Better Workaround:_ Someone sufficiently interested could
[provide a patch][cg] to add a `<noscript>` wrapped HTML button that
would reload the page with this parameter included/excluded to implement
the toggle via a server round-trip.
A related feature is Fossil’s JavaScript-based interactive method
for selecting a range of lines by clicking the line numbers when they’re
visible. JavaScript lets us copy the resulting URL to the clipboard
to share your selection with others.
_Workaround:_ These interactive features would be difficult and
expensive (in terms of network I/O) to implement without JavaScript. A
far simpler alternative is to manually edit the URL, per above.
[mainc]: https://fossil-scm.org/home/artifact?ln&name=87d67e745
### <a id="sxsdiff"></a>Side-by-Side Diff Mode
The default “diff†view is a side-by-side mode. If either of the boxes
of output — the “from†and “to†versions of the repo contents for that
check-in — requires a horizontal scroll bar given the box content, font
size, browser window width, etc., both boxes will usually end up needing
to scroll since they should contain roughly similar content. Fossil
therefore scrolls both boxes when you drag the scroll bar on one because
if you want to examine part of a line scrolled out of the HTML element
in one box, you probably want to examine the same point on that line in
the other box.
_Graceful Fallback:_ Manually scroll both boxes to sync their views.
### <a id="diffcontext"></a>Diff Context Loading
Fossil’s diff views can
dynamically load more lines of context around changed blocks. The UI
controls for this feature are injected using JavaScript when the page
initializes and make use of XHR requests to fetch data from the
fossil instance.
_Graceful Fallback:_ The UI controls for this feature do not appear
when JS is unavailable, leaving the user with the "legacy" static diff
view.
### <a id="sort"></a>Table Sorting
On pages showing a data table, the column headers may be clickable to do
a client-side sort of the data on that column.
_Potential Workaround:_ This feature could be enhanced to do the sort on
the server side using a page re-load.
### <a id="tree"></a>File Browser Tree View
The [file browser’s tree view mode][tv] uses JavaScript to handle clicks
on folders so they fold and unfold without needing to reload the entire
page.
_Graceful Fallback:_ When JavaScript is disabled, clicks on folders
reload the page showing the folder contents instead. You then have to
use the browser’s Back button to return to the higher folder level.
[tv]: https://fossil-scm.org/home/dir?type=tree
### <a id="hash"></a>Version Hashes
In several places where the Fossil web UI shows a check-in hash or
similar, hovering over that check-in shows a tooltip with details about
the type of artifact the hash refers to and allows you to click to copy
the hash to the clipboard.
_Graceful Fallback:_ When JavaScript is disabled, these tooltips simply
don’t appear, but you can still select and copy the hash using your
platform’s “copy selected text†feature.
### <a id="bots"></a>Anti-Bot Defenses
Fossil has [anti-bot defenses][abd], and it has some JavaScript code
that, if run, can drop some of these defenses if it decides a given page
was loaded on behalf of a human, rather than a bot.
_Graceful Fallback:_ You can use Fossil’s anonymous login feature to
convince the remote Fossil instance that you are not a bot. Coupled with
[the Fossil user capability system][caps], you can restore all
functionality that Fossil’s anti-bot defenses deny to random web clients
by default.
[abd]: ./antibot.wiki
[caps]: ./caps/
### <a id="hbm"></a>Hamburger Menu
Several of the stock skins (including the default) include a “hamburger menu†(☰) which uses
JavaScript to show a simplified version of the Fossil UI site map using
an animated-in dropdown.
_Graceful Fallback:_ Clicking the hamburger menu button with JavaScript
disabled will take you to the `/sitemap` page instead of showing a
simplified version of that page’s content in a drop-down.
_Workaround:_ You can remove this button by [editing the skin][cskin]
header.
### <a id="clock"></a>Clock
Some stock Fossil skins include JavaScript-based features such as the
current time of day. The Xekri skin includes this in its header, for
example. A clock feature requires JavaScript to get the time on initial
page load and then to update it once a minute.
You may observe that the server could provide the current time when
generating the page, but the client and server may not be in the same
time zone, and there is no reliably-provided information from the client
that would let the server give the page load time in the client’s local
time zone. The server could only tell you *its* local time at page
request time, not the client’s time. That still wouldn’t be a “clock,â€
since without client-side JavaScript code running, that part of the page
couldn’t update once a second.
_Potential Graceful Fallback:_ You may consider showing the server’s
page generation time rather than the client’s wall clock time in the
local time zone to be a useful fallback for the current feature, so [a
patch to do this][cg] may well be accepted. Since this is not a
*necessary* Fossil feature, an interested user is unlikely to get the
core developers to do this work for them.
### <a id="chat"></a>Chat
The [chat feature](./chat.md) is deeply dependent
on JavaScript. There is no obvious way to do this sort of thing without
active client-side code of some sort.
_Potential Workaround:_ It would not be especially difficult for someone
sufficiently motivated to build a Fossil chat gateway, connecting to
IRC, Jabber, etc. The messages are stored in the repository’s `chat`
table with monotonically increasing IDs, so a poller that did something
like
SELECT xfrom, xmsg FROM chat WHERE msgid > 1234;
…would pull the messages submitted since the last poll. Making the
gateway bidirectional should be possible as well, as long as it properly
uses SQLite transactions.
### <a id="brlist"></a>List of branches
The [`/brlist`](/brlist) page uses JavaScript to enable
selection of several branches for further study via `/timeline`.
Client-side script interactively responds to checkboxes' events
and constructs a special hyperlink in the submenu.
Clicking this hyperlink loads a `/timeline` page that shows
only these selected branches (and the related check-ins).
_Potential Workaround:_ A user can manually construct an appropriate
regular expession and put it into the "Tag Filter" entry of the
`/timeline` page (in its advanced mode).
----
## <a id="future"></a>Future Plans for JavaScript in Fossil
As of mid-2020, the informal provisional plan is to increase Fossil
UI's use of JavaScript considerably compared to its historically minimal
uses. To that end, a framework of Fossil-centric APIs is being developed
in conjunction with new features to consolidate Fossil's historical
hodgepodge of JavaScript snippets into a coherent code base.
When deciding which features to port to JavaScript, the rules of thumb
for this ongoing effort are:
- Pages which primarily display data (e.g. the timeline) will remain
largely static HTML with graceful fallbacks for all places they do
use JavaScript. Though JavaScript can be used effectively to power
all sorts of wonderful data presentation, Fossil currently doesn't
benefit greatly from doing so. We use JavaScript on these pages only
to improve their usability, not to define their primary operations.
- Pages which act as editors of some sort (e.g. the `/info` page) are
prime candidates for getting the same treatment as the old wiki
editor: reimplemented from the ground up in JavaScript using Ajax
type techniques. Similarly, a JS-driven overhaul is planned for the
forum’s post editor.
These are guidelines, not immutable requirements. Our development
direction is guided by our priorities:
1) Features the developers themselves want to have and/or work on.
2) Features end users request which catch the interest of one or more
developers, provided the developer(s) in question are in a position to
expend the effort.
3) Features end users and co-contributors can convince a developer into
coding even when they really don't want to.
In all of this, Fossil's project lead understandably has the final
say-so in whether any given feature indeed gets merged into the mainline
trunk. Development of any given feature, no matter how much effort was
involved, does not guarantee its eventual inclusion into the public
releases.

# Checkin Artifacts (Commits)
Returns information about checkin artifacts (commits).
**Status:** implemented 201110xx
**Request:** `/json/artifact/COMMIT_HASH`
**Required permissions:** "o" (was "h" prior to 20120408)
**Response payload example: (CHANGED SIGNIFICANTLY ON 20120713)**
```json

"parents":[
// 1st entry is primary parent hash:

// Remaining entries are merged-in branch hashes:

"dbf4ecf414881c9aad6f4f125dab9762589ef3d7"\
],
"tags":["trunk"],
"files":[{
"name":"src/diff.c",
// BLOB hashes, NOT commit hashes:
"uuid":"78c74c3b37e266f8f7e570d5cf476854b7af9d76",
"parent":"b1fa7e636cf4e7b6ed20bba2d2680397f80c096a",
"state":"modified",

},
...]
}
```
The "parents" property lists the parent hashes of the checkin. The
"parent" property of file entries refers to the parent hash of that
file. In the case of a merge there may be essentially an arbitrary
number. The first entry in the list is the "primary" parent. The primary
parent is the parent which was not pulled in via a merge operation. The
ordering of remaining entries is unspecified and may even change between
calls. For example: if, from branch C, we merge in A and B and then
commit, then in the artifact response for that commit the hash of branch
C will be in the first (primary) position, with the hashes for branches A
and B in the following entries (in an unspecified, and possibly
unstable, order).
Note that the "uuid" and "parent" properties of the "files" entries
refer to raw blob hashes, not commit (a.k.a. check-in) hashes. See also
[the UUID vs. Hash discussion][uvh].
<a id="file"></a>
# File Artifacts
Fetches information about file artifacts.
**FIXME:** the content type guessing is currently very primitive, and
may (but I haven't seen this) mis-diagnose some non-binary files as
binary. Fossil doesn't yet have a mechanism for mime-type mappings.
**Status:** implemented 20111020
**Required permissions:** "o"
**Request:** `/json/artifact/FILE_HASH`
**Request options:**
- `format=(raw|html|none)` (default=none). If set, the contents of the
artifact are included if they are text, else they are not (JSON does
not do binary). The "html" flag runs it through the wiki parser. The
results of doing so are unspecified for non-embedded-doc files. The
"raw" format means to return the content as-is. "none" is the same
as not specifying this flag, and elides the content from the
response.
- DEPRECATED (use format instead): `includeContent=bool` (=false) (CLI:
`--content|-c`). If true, the full content of the artifact is returned
for text-only artifacts (but not for non-text artifacts). As of
20120713 this option is only inspected if "format" is not specified.
**Response payload example: (CHANGED SIGNIFICANTLY ON 20120713)**
```json
{
"type":"file",
"name":"same name specified as FILE_HASH argument",
"size": 12345, // in bytes, independent of format=...
"parent": "hash of parent file blob. Not set for first generation.",
"checkins":[{
"name":"src/json_detail.h",
"timestamp":1319058803,
"comment":"...",
"user":"stephan",
"checkin":"d2c1ae23a90b24f6ca1d7637193a59d5ecf3e680",
"branch":"json",
"state":"added|modified|removed"
},
...],
/* The following "content" properties are only set if format=raw|html */
"content": "file contents",
"contentSize": "size of content field, in bytes. Affected by the format option!",
"contentType": "text/plain", /* currently always text/plain */
"contentFormat": "html|raw"
}
```
The "checkins" array lists all checkins which include this file, and a
file might have different names across different branches. The size and
hash, however, are the same across all checkins for a given blob.
<a id="wiki"></a>
# Wiki Artifacts
Returns information about wiki artifacts.
**Status:** implemented 20111020, fixed to return the requested version
(instead of the latest) on 20120302.
**Request:** `/json/artifact/WIKI_HASH`
**Required permissions:** "j"
**Options:**
- DEPRECATED (use format instead): `bool includeContent` (=false). If
true then the raw content is returned with the wiki page, else no
content is returned.\
CLI: `--includeContent|-c`
- The `--format` option works as for
[`/json/wiki/get`](api-wiki.md#get), and if set then it
implies the `includeContent` option.
**Response payload example:**
Currently the same as [`/json/wiki/get`](api-wiki.md#get).

# Introduction
**FIXME:** Ross found a bug:
[](/info/479aadb1d2645601)
(sending the authToken via `POST.envelope` isn't working. It should be.)
The authentication-related operations are described in this section
(ordered alphabetically by operation name).
The JSON API ties in to/piggybacks on fossil's existing cookie-based
login mechanism, but we must also keep in mind that not all JSON-using
clients support cookies. Cookie-capable clients can rely on cookies for
authentication, whereas non-cookie-aware clients will need to keep track
of the so-called "auth token" which is created via a login request, and
pass it in with each request (either as a GET parameter or a property of
the top-level POST request envelope) to prove to fossil that they are
authorized to access the requested resources. For most intents and
purposes, the "auth token" and the "login cookie" are the same thing (or
serve the same purpose), and the auth token is in fact just the value
part of the login cookie (which has a project-specific key).
Note that fossil has two conventional user names which can show up in
various responses but do not refer to specific people: nobody and
anonymous. The nobody user is anyone who is not logged in. The anonymous
user is logged in but has no persistent user data (no associated user
name, email address, or similar). Normally the guest (nobody) user has
more access restrictions. The distinction between the two is largely
historical - it is a mechanism to keep bots from following the
multitudes of links generated by the HTML interface (especially the ZIP
files), while allowing interested users to do so by logging in as the
anonymous user (which bots have (or *had*, at the time) a harder time
doing because the password is randomly generated and protected from
brute-force attacks by hashing). In the JSON API, the distinction
between anonymous and nobody is not expected to be as prominent as it is
in the HTML interface because the reasons for the distinction don't
apply in *quite* the same ways to the JSON interface. It is possible,
however, that a given repo locks out guest access to, e.g. the wiki or
tickets, while still allowing anonymous (logged in) access.
<a id="capabilities"></a>
# Capabilities (Access Rights)
The "cap" request returns information about the so-called "capabilities"
(access rights) of the currently logged in user. This command is
basically the same as the "whoami" command, but returns capabilities in
a more exanded form (same data, different representation) and does not
include the authToken in the response.
TODO: consider combining this and [whoami](#whoami) into a single
whoami response. We don't need both. We also don't really need the
permissionFlags member - the same info is already \[in a more cryptic form\]
in the capabilities string.
**Status:** implemented 201109xx.
**Required privileges:** none
**Request:** `/json/cap`
In CLI mode, permissions are not used/honored, and this command will
report that the caller has all permissions (which he effectively does).
**Response payload example:**
```json
{
"userName":"json-demo",
"capabilities":"hgjorxz", /* raw fossil permissions list */
"permissionFlags":{ /* Same info in a somewhat friendlier form */
"setup": false,
"admin": false,
"delete": false,
"password": false,
"query": false,
"checkin": false,
"checkout": true,
"history": true,
"clone": false,
"readWiki": true,
"createWiki": false,
"appendWiki": false,
"editWiki": false,
"readTicket": true,
"createTicket": false,
"appendTicket": false,
"editTicket": false,
"attachFile": false,
"createTicketReport": false,
"readPrivate": false,
"zip": true,
"xferPrivate": false
}
}
```
**FIXME:** several new permissions have been added to fossil since
this API was implemented.
<a id="login"></a>
# Login
**Status:** implemented 20110915 (anonymous login 20110918)
**Required privileges:** none
**Request:** (see below for Anonymous user special case)
- `/json/login?name=...&password=...`
- `/json/login?n=...&p=...` (for symmetry with existing login mechanism)
Or `POST.payload`: `{ "name": ..., "password": ...}`
(POST is highly preferred because it keeps the password out of web
server logs!)
**Response payload example:** (structure changed 20111001)
```json
{
"authToken":"...",
"name":"json-demo",
"capabilities":"hgjorxz",
"loginCookieName": "fossil-XXXXX" /*project-specific cookie name*/
/* TODO: add authTokenExpiry timestamp (cookie expiry time) */
}
```
We "should" be able to inherit fossil's `REMOTE_USER` handling without
any special support, but that is untested so far. (If you happen to test
this, please update this doc with (or otherwise report) your results!)
The response *also* sets the conventional fossil login cookie (for
clients which can make use of cookies), using fossil's existing
mechanism for this.
Further requests which require authentication must include the
`authToken` (from the returned payload value) in the request (or it must
be available via fossil's standard cookie) or access may (depending on
the request) be denied. The `authToken` may optionally be set in the
request envelope or as a GET parameter, and it *must* be given if the
request requires restricted access to a resource. e.g. if reading
tickets is disabled for the guest user then all non-guest users must
send authentication info in their requests in order to be able to fetch
ticket info.
Cookie-aware clients should send the login-generated cookie with each
request, in which case they do not need to explicitly include the
`authToken` in the JSON envelope/GET arguments. If submitted, the
`authToken` is used, otherwise the cookie, if set, is used. Note that
fossil uses a project-dependent cookie name in order to help thwart
attacks, so there is no simple mapping of cookie *name* to auth
token. That said, the cookie's *value* is also the auth token's value.
> Special case: when accessing fossil over a local server instance
which was started with the `--localauth` flag, the `authToken` is ignored
(neither validated nor used for any form of authentication).
<a id="login-anonymous"></a>
## Anonymous User Logins
The Anonymous user requires special handling because he has a random
password.
First fetch the password and the so-called "captcha seed" via this
request:
`/json/anonymousPassword`
It will return a payload in the form:
```json
{
"seed": a_32_bit_unsigned_integer,
"password": "1234abcd" /*hexadecimal STRING*/
}
```
The "seed" and "password" values of the response payload must be set as
the "anonymousSeed" and "password" fields (respectively) of the
subsequent login request. The login request is identical to
non-anonymous login except that extra "anonymousSeed" property is
required.
The password value *may* be time-limited, and *may* eventually become
invalidated due to old age. This is unspecified.
***Potential***** (low-probability) bug regarding the seed value:** from
what I hear, some unusual JSON platforms don't support full 32-bit
precision. If absolutely necessary we could chop off a bit or two from
the seed value (*if* it ever becomes a problem and if DRH blesses it).
Or we could just make it a double.
<a id="logout"></a>
# Logout
**Status:** implemented 20110916
**Required privileges:** none, but must be logged in
**Request:**
- `/json/logout?authToken=...token fetched by /login`
Or: set the `authToken` property of the POST envelope (as opposed to the
`POST.payload`)
Or: fossil's normal cookie mechanism is the fallback for the auth token.
**Response payload:** The same as the "whoami" response, containing the
info for the "nobody" user.
This request requires the authentication token, and subsequent logouts
without an intervening login will fail with the "auth token not
provided" error. In effect this request removes the login entry from the
user account, making the token invalid for future requests. In HTTP
mode, on success fossil's login cookie is unset by this call.
<a id="whoami"></a>
# Whoami
This request fetches the current user's login name, capabilities, and
auth token. This can be used to check whether a login is active when the
client has not explicitly logged in (e.g. was logged in automatically
via a pre-existing cookie).
**Status:** implemented 20110922
**Required privileges:** none
**Request:** `/json/whoami`
**Response payload example:**
```json
{
"name": "nobody",
"capabilities": "o",
"authToken": "fossil auth token (only for logged-in users)"
}
```
The reason authToken is included in the response is because it gives
client-side JavaScript code a way of fetching/checking for the auth
token at app startup. The token is normally sent as a cookie but parsing
the cookies in the browser is tedious, and fossil has a
project-dependent cookie name (which complicates parsing a bit). If
client code digs the cookie out of the browser, the app still wouldn't
know if the token is still valid, whereas whoami won't (or shouldn't!)
return an expired auth token. If the request does not include
authentication info (via the cookie, GET param, or request envelope)
then the response will not contain the authToken property and the user's
name will be "nobody".

# Branch List
**Status:** implemented, at least in draft form, on 20110921.
**Required privileges:** "o"
**Request:** `/json/branch/list`
**Response payload example:**
```json
{
"range":"closed",
"current":"json", /* only when there is a local opened checkout */
"branches":[
"artifact_description",
"bch",
"ben-changes-report",
"ben-safe-make",
"ben-security",
"ben-testing",
…
]
}
```
*Potential* TODO: add "tip" property which names the most recently
modified branch? (How to get this?)
HTTP GET/`POST.payload` options:
- `range`: a string in the set ("open", "closed", "all"),
case-sensitive, but only the first letter is actually evaluated.
Default="open". Only branches with this state are returned.
CLI mode options (same semantics as HTTP equivalents), must come last on
the CLI:
- `-r|--range all|closed|open`
- `-a` (equivalent to `-r all`)
- `-c` (equivalent to `-r closed`). Only one of `-a`/`-c` may be specified,
and if both are specified then which one takes precedence is
unspecified.
<a id="create"></a>
# Create Branch
**Status:** implemented 20111002
**Required privileges:** "w"
**Request:** `/json/branch/create`
**Request options:**
- `name=string` (REQUIRED) Name of new branch
- `basis=string` (default=trunk) Name of parent branch to branch from.
- `bgColor=string` (default=something ugly) In `#RRGGBB` form. (FIXME:
change the default to use fossil's random bgcolor technique.)
- `private=bool` (default=false) Determines whether the branch is
private or not.
**Response payload example:**
```json
{
"name":"my-branch",
"basis":"my-other-branch",
"uuid":"de8115db4ce388ed8d0af666ae7d90e1410be4ca",

# JSON API: /status
([⬑JSON API Index](index.md))
# Status of Local Checkout
**Status:** implemented 20130223
**Required permissions:** n/a (local access only)
**Request:** `/json/status`
This command requires a local checkout and is the analog to the "fossil
status" command.
**Request Options:** currently none.
Payload example:
```json
{
"repository":"/home/stephan/cvs/fossil/fossil.fsl",
"localRoot":"/home/stephan/cvs/fossil/fossil/",
"checkout":{
"uuid":"b38bb4f9bd27d0347b62ecfac63c4b8f57b5c93b",
"tags":["trunk"],
"datetime":"2013-02-22 17:34:19 UTC",
"timestamp":1361554459
},
/* "parent" info is currently missing. */
"files":[
{"name":"src/checkin.c", "status":"edited"}
...],
"errorCount":0 /* see notes below */
}
```
Notes:
- The `checkout.tags` property follows the framework-wide convention
that the first tag in the list is the primary branch and any others
are secondary.
- `errorCount` is +1 for each missing file. Conflicts are not treated as
errors because the CLI 'status' command does not treat them as such.
- The `"status"` entry for each of the `"files"` entries will be either a
single string containing a single description of the status change, or
an array of strings if more than one change was made, e.g. `"edited"`
and `"renamed"`. The status strings include:\
`deleted`, `new`, `notAFile`, `missing`, `updatedByMerge`,
`updatedByIntegrate`, `addedBymerge`, `addedByIntegrate`,
`conflict`, `edited`, `renamed`
- File objects with a `"renamed"` status will contain a `"priorName"`
property in addition to the `"name"` property reported in all cases.
- TODO: Info for the parent version is currently missing.
- TODO: "merged with" info for the checkout is currently missing.

# Diffs
**Status:** implemented 20111007
**Required permissions:** "o"
**Request:** `/json/diff[/version1[/version2]]`
**Request options:**
- `v1=string` Is the "from" version. It may optionally be the first
positional parameter/path element after the command name.
- `v2=string` Is the "to" version. It may optionally be the first
positional parameter/path element after the v1 part.
- `context=integer` (default=unspecified) Defines the number of context
lines to display in the diff.\
CLI: `--context|-c`
- `sbs=bool` (default=false) Generates "side-by-side" diffs, but their
utility in JSON mode is questionable.
- `html=bool` (default=false) causes the output to be marked up with
HTML in the same manner as it is in the HTML interface.
**Response payload example:**
```json
{
"from":"7a83a5cbd0424cefa2cdc001de60153aede530f5",
"to":"96920e7c04746c55ceed6e24fc82879886cb8197",
"diff":"@@ -1,7 +1,7 @@\\n-C factored\\\\sout..."
}
```
TODOs:
- Unlike the standard diff command, which apparently requires a commit
hash, this one diffs individual file versions. If a commit hash is
provided, a diff of the manifests is returned. (That should be
considered a bug - we should return a combined diff in that case.)
- If hashes from two different types of artifacts are given, results
are unspecified. Garbage in, garbage out, and all that.
- For file diffs, add the file name(s) to the response payload.

# JSON API: /dir
([⬑JSON API Index](index.md))
# Directory Listing
**Status:** implemented 20120316
**Required privileges:** "o". Was "h" prior to 20120720, but the HTML
version of /dir changed permissions and this API was modified to match
it.
**Request:** `/json/dir`
Options:
- `checkin=commit` (use "tip" for the latest). If checkin is not set
then all files from all versions of the tree are returned (but only
once per file - not with complete version info for each file in all
branches).\
CLI: `--checkin|-ci CHECKIN`
- `name=subdirectory` name. To fetch the root directory, don't pass this
option, or use an empty value or "/".\
CLI: use `--name|-n NAME` or pass it as the first argument after
the `dir` subcommand.
**Response payload example:**
```json
{
"name":"/", /* dir name */
"uuid":"ac6366218035ed62254c8d458f30801273e5d4fc",
"checkin":"tip",
"entries":[{
"name": "ajax", /* file name/dir name fragment */
"isDir": true, /* only set for directories */
/* The following properties are ONLY set if
the 'checkin' parameter is provided.
*/
"uuid": "..." /*only for files, not dirs*/,
"size": number,
"timestamp": number
},...]
}
```
The checkin property is only set if the request includes it. The
entry-specific uuid and size properties (e.g. `entries[0].uuid`) are
only set if the checkin request property is set and they refer to the
latest version of that file for the given checkin. The `isDir` property is
only set on directory entries.
This command does not recurse into subdirectories, though it "should be"
simple enough to add the option to do so.

# JSON API: /finfo
([⬑JSON API Index](index.md))
# File Information
**Status:** implemented 2012-something, but output structure is likely
to change.
**Required privileges:** "o"
**Request:** `/json/finfo?name=path/to/file`
Options:
- `name=string`. Required. Use the absolute name of the file, including
any directory parts, and without a leading slash. e.g.
`"path/to/my.c"`.\
CLI mode: `--name` or positional argument.
- `checkin=string`. Only return info related to this specific checkin,
as opposed to listing all checkins. If set, neither "before" nor
"after" have any effect.\
CLI mode: `--checkin|-ci`
- `before=DATETIME` only lists checkins from on or before this time.\
CLI mode: `--before|-b`
- `after=DATETIME` only lists checkins from on or after this time.
Using this option swaps the sort order, to provide reasonable
behaviour in conjunction with the limit option.\
Only one of "before" and "after" may be specified, and if both are
specified then which one takes precedence is unspecified.\
CLI mode: `--after|-a`
- `limit=integer` limits the output to (at most) the given number of
associated checkins.\
CLI mode: `--limit|-n`
**Response payload example (very likely to change!):**
```json
{
"name":"ajax/i-test/rhino-shell.js",

# Global State ("g")
Fossil's internal state is maintained in a global object called "g". And
thus this command is named "g"...
**Status:** implemented 20111009
**Required permissions:** "a" or "s"
**Request:** `/json/g`
**Response payload example:** this is a debugging-only request, and has
no stable response payload structure. The result object contains all
kinds of details gleaned from the fossil environment.
Easter egg: this output can be added to ANY response by passing the
`debugFossilG` boolean in the POST envelope or GET parameters, or as the
`--json-debug-g` flag in CLI mode. This requires admin or setup
privileges, though, and it is silently ignored for other users.
<a id="rebuild"></a>
# Rebuild Repository
This request does the same as the "fossil rebuild" command, rebuilding
the repo-internal structure. This is often required after upgrading the
fossil binary on a system. There "are very probably" cases where calling
this over HTTP will not work (e.g. if the user table has changed enough
that the access rights cannot be validated without a rebuild, i.e. a
chicken/egg scenario). Another consideration is that this request can
take a long time to run - rebuilding the fossil repo on my laptop takes
about 21 seconds, which is likely longer than the timeout set on an XHR
request, meaning that the rebuild transaction will fail. It can safely
be run in CLI mode, where timeouts are not normally a concern. As a
preliminary benchmark: rebuilding the fossil repo (as of late 2011)
takes just over 21 seconds on my 32-bit 1.6GHz netbook. That said, most
repos are much smaller and rebuild in under a few seconds.
**Status:** implemented 20110929
**Required privileges:** "a"
**Request:** `/json/rebuild`
Requires admin access rights.
**Response payload:** none (response envelope `resultCode` reports failure).
Potential TODO: return the amount of time it took to rebuild.
<a id="result-codes"></a>
# Result Code Descriptions
This request returns the full list of result codes documented for
Fossil's JSON API. Each result code is returned as an object containing
metadata about the result code.
**Status:** implemented 20111006
**Required permissions:** none
**Request:** `/json/resultCodes`
**Response payload example:**
```json
[{
"resultCode":"FOSSIL-1000",
"cSymbol":"FSL_JSON_E_GENERIC",
"number":1000,
"description":"Generic error"
},
… many more objects with the same structure …
]

# JSON API: /query
([⬑JSON API Index](index.md))
# SQL Query
**Status:** implemented 20111008
**Required privileges:** "a" or "s"
**Request:** `/json/query`
Potential FIXME: restrict this to queries which return results, as opposed
to those which may modify data.
Options:
- `sql=string` The SQL code to run. It is expected that it be a SELECT
statement, but that is not enforced. This parameter may be set as a
POST.payload property, as the POST.payload itself, GET, or as a
positional parameter coming after the command name (CLI and HTTP
modes, though the escaping would be unsightly in HTTP mode).
- `format=string` (default="o"). "o" specifies that each result row
should be in the form of key/value pairs (o=object). "a" means each
row should be an array of values.
**Example request:**
POST to: `/json/query`
```json
{
"authToken": "...",
"payload": {
"sql": "SELECT * FROM reportfmt",
"format": "o"
}
}
```
**Response payload example:** (assuming the above example)
```
{
"columns":[
"rn",
"owner",
"title",
"mtime",
"cols",
"sqlcode"
],
"rows":[
{
"rn":1,
"owner":"drh",
"title":"All Tickets",
"mtime":1303870798,
},
…
]
}
```
The column names are provided in a separate field because their order
is guaranteed to match the order of the query columns, whereas object
key/value pairs might get reordered (typically sorted by key) when
travelling through different JSON implementations. In this manner,
clients can e.g. be sure to render the columns in the proper
(query-specified) order.
When in "array" mode the "rows" results will be an array of arrays. For
example, the above "rows" property would instead look like:
`[ [1, "drh", "All Tickets", 1303870798, … ], … ]`
Note the column *names* are never *guaranteed* to be exactly as they
appear in the SQL *unless* they are qualified with an AS, e.g. `SELECT
foo AS foo...`. When generating reports which need fixed column names, it
is highly recommended to use an AS qualifier for every column, even if
they use the same name as the column. This is the only way to guarantee
that the result column names will be stable. (FYI: that behaviour comes
from sqlite3, not the JSON bits, and this behaviour *has* been known to
change between sqlite3 versions (so this is not just an idle threat of
*potential* future incompatibility).)

# Fetch Settings
**Status:** Implemented 20230120
**Required permissions:** "o"
**Request:** `/json/settings/get[?version=X]`
**Response payload example:**
```json
{
"access-log":{
"versionable":false,
"sensitive":false,
"defaultValue":"off",
"valueSource":null,
"value":null
},
...
"binary-glob":{
"versionable":true,
"sensitive":false,
"defaultValue":null,
"valueSource":"versioned",
"value":"*.gif\n*.ico\n*.jpg\n*.odp\n*.dia\n*.pdf\n*.png\n*.wav..."
},
...
"web-browser":{
"versionable":false,
"sensitive":true,
"defaultValue":null,
"valueSource":"repo",
"value":"firefox"
}
}
```
Each key in the payload is the name of a fossil-recognized setting,
modeled as an object. The keys of that are:
- `defaultValue`: the setting's default value, or `null` if no default
is defined.
- `value`: The current value of that setting.
- `valueSource`: one of (`"repo"`, `"checkout"`, `"versioned"`, or
`null`), specifying the data source where the setting was found. The
settings sources are checked in this order and the first one found
is the result:
- If `version=X` is provided, check-in `X` is searched for a
versionable-settings file. If found, its value is used and
`valueSource` will be `"versioned"`. If `X` is not a checkin, an
error response is produced with code `FOSSIL-3006`.
- If a versionable setting is found in the current checkout, its
value is used and `valueSource` will be `"versioned"`
- If the setting is found in checkout database's `vvar` table, its
value is used and `valueSource` will be `"checkout"`.
- If the setting is found in repository's `config` table, its
value is used and `valueSource` will be `"repo"`.
- If no value is found, `null` is used for both the `value` and
`valueSource` results. Note that _global settings are never
checked_ because they can leak information which have nothing
specifically to do with the given repository.
- `sensitive`: a value which fossil has flagged as sensitive can only
be fetched by a Setup user. For other users, they will always have
a `value` and `valueSource` of `null`.
- `versionable`: `true` if the setting is tagged as versionable, else
`false`.
Note that settings are internally stored as strings, even if they're
semantically treated as numbers. The way settings are stored and
handled does not give us enough information to recognize their exact
data type here so they are passed on as-is.
<a id="set"></a>
# Set Settings
**Status:** Implemented 20230120
**Required permissions:** "s"
**Request:** `/json/settings/set`
This call requires that the input payload be an object containing a
mapping of fossil-known configuration keys (case-sensitive) to
values. For example:
```json
{
"editor": "emacs",
"admin-log": true,
"auto-captcha": false
}
```
It iterates through each property, which must have a data type of
`null`, boolean, number, or string. A value of `null` _unsets_
(deletes) the setting. Boolean values are stored as integer 0
or 1. All other types are stored as-is. It only updates the
`repository.config` database and never updates a checkout or global
config database, nor is it capable of updating versioned settings
(^Updating versioned settings requires creating a full check-in.).
It has no result payload but this may be changed in the future it
practice shows that it should return something specific.
Error responses include:
- `FOSSIL-2002`: called without "setup" permissions.
- `FOSSIL-3002`: called without a payload object.
- `FOSSIL-3001`: passed an unknown config option.
- `FOSSIL-3000`: a value has an unsupported data type.
If an error is triggered, any settings made by this call up until that
point are discarded.

```
**Options:**
- "Full detail" mode:\
**HTTP/payload parameter:** full=bool\
**CLI MODE:** -f|--full with no value.\
If true then all properties are included, else certain properties
are omitted from the payload (because they take a relatively long
time to calculate).\
**TODO:** rename this to verbose, for consistency.\
**Default=false**. *This is in contrast to the HTML interface*,
which defaults to full detail mode. Testing shows stat to have a
relatively high per-call cost/run time, so it defaults
to "brief" mode by default. Full-detail mode can, on slow hardware,
take half a minute to respond, whereas non-full mode takes well
under one second.

# Add Tag
**Status:** implemented 20111006
**Required permissions:** "i"
**Request:** `/json/tag/add[/name[/checkin[/value]]]`
**Request options:**
- `name=string` The tag name.
- `checkin=string` The checkin to tag. May be a symbolic branch name.
- raw=bool (=false) If true, then the name is set as it is provided by
the client, else it gets "sym-" prefixed to it. Do not use this
unless you really know what you're doing.
- `value=string` (=null) An optional value. While tags *may* have values
in fossil, it is unusual for them to have a value. (This probably
has some interesting uses in custom UIs.)
- `propagate=bool` (=false) Sets the tag to propagate to all descendants
of the given checkin.
In CLI modes, the name, checkin, and value parameters may optionally be
supplied as positional parameters (in that order, after the command
name). In HTTP mode they may optionally be the 4th-6th path elements or
specified via GET/`POST.envelope` parameters.
**Response payload example:**
```json
{
"name":"my-tag",
"value":"abc",
"propagate":true,
"raw":false,
"appliedTo":"626ab2f3743543122cc11bc082a0603d2b5b2b1b"
}
```
The `appliedTo` property is the hash of the check-in to which the tag was
applied. This is the "resolved" version of the check-in name provided by
the client.
<a id="cancel"></a>
# Cancel Tag
**Status:** implemented 20111006
**Required permissions:** "i"
**Request:** `/json/tag/cancel[/name[/checkin]]`
**Request options:**
- `name=string` The tag name. May optionally be provided as the 4th path
element.
- `checkin=string` The checkin to untag. May be a symbolic branch name.
May optionally be provided as the 5th path element.
In CLI modes, the name and checkin parameters may optionally be supplied
as positional parameters (in that order, after the command name) or
using the `-name NAME` and `-checkin NAME` options. In HTTP mode they may
optionally be the 4th and 5th path elements.
**Response payload:** none (resultCode indicates failure)
<a id="find"></a>
# Find Tag
Fetches information about artifacts having a particular tag.
Achtung: the output of this response is based on the HTML-mode
implementation, but it's not yet certain that it's exactly what we want
for JSON mode. The request options and response format may change.
**Status:** implemented 20111006
**Required permissions:** "o"
**Request:** `/json/tag/find[/tagName]`
The response format differs somewhat depending on the options:
- `name=string` The tag name to search for. Can optionally be the 3rd
path element.
- `limit=int` (defalt=0) Limits the number of results (0=no limit).
Since they are ordered from oldest to newest, the newest N results
will be returned.
- `type=string` (default=`*`) Searches only for the given type of
artifact (using fossil's conventional type naming: ci, e, t, w.)
- `raw=bool` (=false) If enabled, the response is an array of hashes
of the requested artifact type; otherwise,
it is an array of higher-level objects. If this is
true, the "name" property is interpreted as-is. If it is false, the
name is automatically prepended with "sym-" (meaning a branch).
(FIXME: the current semantics are confusing and hard to remember.
Re-do them.)
**Response payload example, in RAW mode: (expect this format to change
at some point!)**
```json
{
"name":"sym-trunk"
"raw":true,
"type":"*",
"limit":2,
"artifacts":[
"a28c83647dfa805f05f3204a7e146eb1f0d90505",
"dbda8d6ce9ddf01a16f6c81db2883f546298efb7"
]
}
```
Very likely todo: return more information with that (at least the
artifact type and timestamp). Once the `/json/artifact` family of bits is
finished we could use that to return artifact-type-dependent values
here.
**Response payload example, in non-raw mode:**
```
{
"name":"trunk",
"raw":false,
"type":"*",
"limit":1,
"artifacts":[{
"uuid":"4b0f813b8c59ac8f7fbbe33c0a369acc65407841",
"timestamp":1317833899,
"comment":"fixed [fc825dcf52]",
"user":"ron",
"eventType":"checkin"
}]
}
```
<a id="list"></a>
# List Tags
**Status:** implemented 20111006
**Required permissions:** "o"
**Request:** `/json/tag/list[/checkinName]`
Potential fixme: we probably have too many different response formats
here. We should probably break this into multiple subcommands.
The response format differs somewhat depending on the options:
- `checkin=string` Lists the tags only for the given CHECKIN (can be a
branch name). If set, includeTickets is ignored (meaningless in this
combination). This option can be set as either a GET/`POST.payload`
option, as the last element of the request path, e.g.
`/json/tag/list/MYBRANCH` *or* with `POST.payload` set to a string
value.
- `raw=bool` (default=false) uses "raw" tag names
- `includeTickets=bool` (default=false) Determines whether `tkt-` tags
are included. There is one of these for each ticket, so there can be
many of them (over 900 in the main fossil repo as of this writing).
**Response format when raw=false and no checkin is specified:**
```json
{
"raw":false,
"includeTickets":false,
"tags":[
"bgcolor",
"branch",
"closed",
…all tag names...
]
}
```
Enabling the `raw` option will leave the internal `sym-` prefix on tags
which have them but will not change the structure. If `includeTickets` is
true then `tkt-` entries (possibly very many!) will be included in the
output, else they are elided.
**General notes:**
The `tags` property will be null if there are no tags, every non-empty
repo has at least one tag (for the trunk branch).
**Response format when raw=false and checkin is specified:**
```json
{
"raw":false,
"tags":{
"json":null,
"json-multitag-test":null
}
}
```
The `null`s there are the tag values (most tags don't have values).
If `raw=true` then the tags property changes slightly:
```json
{
"raw":true,
"tags":{
"branch":"json",
"sym-json":null,
"sym-json-multitag-test":null
}
}
```
TODO?: change the tag values to objects in the form
`{value:..., tipUuid:string, propagating:bool}`.

# Tickets
This API is incomplete. It is missing at least the following features:
- Content for a given ticket ID
- History for a given ticket ID?
- An option to enable/disable the generation of hyperlinks, as links
won't be useful in most non-browser clients.
<a id="reports"></a>
# Ticket Reports
<a id="report-get"></a>
## Fetch a Report
**Status:** implemented 20111008
**Required privileges:** "t" (the thinking being that only those
permitted to create reports should be able to read their SQL code)
**Request:** `/json/report/get[/REPORT_NUMBER]`
**Request options:**
- `report=number` The report number to fetch.\
CLI: `-report|-r` \
(Design note: `--number/-n` was not used because that parameter has a
different meaning (limit response count) in several commands.) May
optionally be defined via the 4th GET path element or CLI arg.
**Response payload example:**
```json
{
"report":1,
"owner":"drh",
"title":"All Tickets",
"timestamp":"112443570187200",
"columns":"#ffffff Key:\r\n#f2dcdc Active\r\n...",
"sqlCode":"..."
}
```
<a id="report-list"></a>
## List Reports
**Status:** implemented 20111008
**Required privileges:** "r" or "n"
**Request:** `/json/report/list`
**Response payload example:**
```json
[
{
"report":1,
"title":"All Tickets",
"owner":"drh"
},
…
]
```
<a id="report-run"></a>
## Run a Report
**Status:** implemented 20111008
**Required privileges:** "r" or "n"
**Request:** `/json/report/run[/REPORT_NUMBER]`
Request options:
- `report|-r=int` Specifies which report to run. May optionally be
supplied as the 4th CLI arg or URL path element.
- `format|-f=string` (default="o") Specifies "array" or "object" output
format.
**Response payload example:**
```json
{
"report":1,
"title":"All Tickets",
"sqlcode": "only set if requester has 't' privileges.",
"columnNames":[ … list of column names … ],
"tickets":[
{
"bgcolor":"#cfe8bd",
"#":"fc825dcf52",
"timestamp":"112443570187200",
"type":"Code_Defect",
"status":"Fixed",
"subsystem":null,
"title":"\"config pull all\" asks to approve ssl cert"
},
…
]
}
```
Note that the column names of ticket reports are determined by the
reports themselves, and not C code. That means that we cannot return a
standard set of column names here. Fossil requires certain column naming
conventions for purposes of styling the HTML interface, e.g. the "\#"
column is always the uuid of the record and "bgcolor" (note the
different casing than bgColor used throughout the rest of this API!) has
a specific meaning to the HTML report browser. Fossil also allows the
tickets to be extended with client-specified fields, so we cannot
generically make these results fit into the API-wide naming scheme. Full
details are here:
[](/doc/trunk/www/custom_ticket.wiki)
and:
[](/rptsql?rn=1)
(That one may require non-default permission.)

# Introduction
These requests return overview-level information about various types of
changes. The response payload differs for each artifact type, and the
current structures are almost certainly not "final" (e.g. we are still
undecided on how/whether to handle artifact links within commit messages
and whatnot).
By default the entries are returned in chronological order from newest
to oldest, but some options might change that.
FIXME (20120623): we have some inconsistent `type` vs. `eventType` in
the result sets. `type` is the current preferred choice (and it seems
unlikely that `eventType` is actually used in any client code). We
don't actually need either one (but a use for `type` is easily
envisioned), and we may get rid of both.
**Common request options (via CLI, GET or POST.payload):**
- `limit=integer` limits the number of entries in the response. Default
is unspecified (but is "quite possibly 20 or so"). A limit value of
0 disables any limit, fetching all entries (which can take a really
long time and might overload clients which have very limited
memory).\
CLI mode: `--limit|-n #`
- `after="YYYY-MM-DD[ HH:mm:ss]"` limits the search to items on or
after the given date string. Reverses the normal timeline sort
order. Alias: "a". Only one of "after" or "before" can be used, and
if both are specified then which one takes precedence is
unspecified.\
CLI mode: `--after|-a "DATE[ TIME]"`
- `before="YYYY-MM-DD[ HH:mm:ss]"` limits the search to items on or
before the given date string.\
CLI mode: `--before|-b "DATE[ TIME]"
- TODOs, still to be ported from the HTML-mode timeline:
- circa=DATETIME
- tag=string
- related=tag name
- string=search string
<a id="branch"></a>
# Branch Timeline
**Status:** partially implemented but undocumented because the utility
of the current impl is under question. It also doesn't understand most
of the common timeline options.
<a id="checkin"></a>
# Checkin Timeline
**Status:** implemented 201109xx
**Required privileges:** "o"
**Request:** `/json/timeline/checkin`
**Response payload example:**
```json
{
"limit": number, /* if not set, all records are returned */
"timeline":[{
"uuid":"be700e84336941ef1bcd08d676310b75b9070f43",
"timestamp":1317094090,
"comment":"Added /json/timeline/ci showFiles to ajax test page.",
"user":"stephan",
"isLeaf":true,
"bgColor":null, /* not quite sure why this is null? */
"type":"ci",
"parents": ["primary parent hash", "...other parent hashes"],
"tags":["json"],
"files":[{
"name":"ajax/index.html",
"uuid":"9f00773a94cea6191dc3289aa24c0811b6d0d8fe",
"parent":"50e337c33c27529e08a7037a8679fb84b976ad0b",
"state":"modified"
}]
},...]
}
```
(Achtung: the `parents` property was called `prevUuid` prior to 20120316.)
The `parents` property lists the checkins which were parents of this
commit. The first entry in the array is the "primary parent" - the one
which was not involved in a merge with the child.
**Request options:**
- `files=bool` toggles the addition of a "files" array property which
contains objects describing the files changed by the commit,
including their hash, previous hash, and state change type
(modified, added, or removed). ([“uuid†here means hash][uvh])\
CLI mode: `--show-files|-f`
- `tag|branch=string` selects only entries with the given tag or "close
to" the given branch. Only one of these may be specified and if both
are specified, which one takes precedence is unspecified. If the
given tag/branch does not exist, an error response is generated. The
difference between the two is subtle - tag filters only on the given
tag (analog to the HTML interface's "r" option) whereas branch can
also return entries from other branches which were merged into the
requested branch (analog to the HTML interface's "b" option). If one
of these is specified, the response payload will contain a "tag"
*or* "branch" property with the tag/branch name given by the client.
<a id="technote"></a>
# Technote (formerly Event) Timeline
**Status:** implemented 20180803
**Required privileges:** "j"
**Request:**
- `/json/timeline/technote`
- DEPRECATED: `/json/timeline/event` (technotes were formerly called `events`)
**Response payload example:**
```json
{
"limit": number, /* if not set, all records are returned */
"timeline":[{
"name":"8d18bf27e9f9ff8b9017edd55afc35701407d418",
"uuid":"b23962c88c123924a77fd663e91af094780d920a",
"timestamp":1478376113,
"comment":"Style update due to [8d880f0bb4]",
"user":"andygoth",
"eventType":"e"
},...]
}
```
The `uuid` of each entry can be passed to `/json/artifact` to fetch the raw
event content.
<a id="ticket"></a>
# Ticket Timeline
**Status:** implemented 201109xx
**Required privileges:** "r" or "o"
**Request:** `/json/timeline/ticket`
**Response payload example:**
```json
{
"limit": number, /* if not set, all records are returned */
"timeline":[{
"uuid":"5065a5da060e181da49a618f8ae5dc245215e95b",
"timestamp":1316511322,
"user":"stephan",
"eventType":"t",
"comment":"Ticket [b64435dba9] <i>How to...</i>",
"briefComment":"Ticket [b64435dba9]: 2 changes",
"ticketUuid":"b64435dba9cceb709bd54fbc5883884d73f93491"
},...]
}
```
**Notice that there are two [hashes][uvh] for tickets** - `uuid` is the change
hash and `ticketUuid` is the actual ticket’s hash. This is an unfortunate
discrepancy vis-a-vis the other timeline entries, which only have one
hash. We may want to swap `uuid` to mean the ticket hash and change `uuid`
to `commitHash`.
<a id="wiki"></a>
# Wiki Timeline
**Status:** implemented 201109xx
**Required privileges:** "j" or "o"
**Requests:**
- `/json/timeline/wiki`
- `/json/wiki/timeline` (alias)
**Response payload example:**
```json
{
"limit": number, /* if not set, all records are returned */
"timeline":[{
"uuid":"4b2026f06eb48eaf187209fcb05ba5438c3b0ef0",
"timestamp":1331351121,
"comment":"Changes to wiki page [Page3]",
"user":"stephan",
"eventType":"w"
},...]
}
```
The `uuid` of each entry can be passed to `/json/artifact` or
`/json/wiki/get?uuid=...` to fetch the raw page and the hash of the
parent version.

# Get User Info
**Status:** implemented 20110927.
**Required privileges:** "a" or "s"
**Request:**
- POST `/json/user/get`\
with `POST.payload.name=USERNAME`
- `/json/user/get?name=USERNAME`
**Response payload example:**
```json
{
"uid":1,
"name":"stephan",
"capabilities":"abcdefhgijkmnopqrstuvwxz",
"info":"https://wanderinghorse.net/home/stephan/",
"timestamp":1316122562
}
```
(What does that timestamp field represent, anyway?)

# List Users
**Status:** implemented 20110927.
**Required privileges:** "a" or "s"
**Request:** `/json/user/list`
**Response payload example:**
```json
[
{
"uid":1,
"name":"stephan",
"capabilities":"abcdefhgijkmnoprstuvwxz",
"info":"",
"timestamp":1316122562
},
... more users...
]
```
<a id="save"></a>
# Save User
Only admin/setup users may modify accounts other than their own.
**Status:** implemented 20111021 *but* it is missing "login group"
support, so changes do not yet propagate to other repos within a group.
**Required privileges:** 'p' or 'a' or 's', depending on the context.
**Request:** `/json/user/save`
All request options must come from the `POST.payload` and/or GET/CLI
parameters (exception: "name" must come from POST.payload or CLI).
GET/CLI parameters take precedence over those in `POST.payload`, the
intention being to use an input file as a template and overriding the
template's defaults via the CLI. The options include:
- `name=string` Specifies the user name to change. When changing a
user's name, the current uid and the new name must be specified.\
**Achtung:** due to fossil-internal ambiguity in the handling of the
"name" parameter, this parameter must come from the `POST.payload`
data or it will not be recognized. In CLI mode it may be specified
with the `--name` flag.
- `uid=int` Specifies the uid to change. At least one of uid or name are
required. A uid of -1 means to create a new user, in which case the
name must be provided.
- `password=string` Optionally changes the user's password. When
renaming existing or creating new users, be sure to always provide a
new password because any old password hash is invalidated by the
name change.
- `info=string` Optionally changes the user's info field.
- `capabilities=string` Optionally changes the user's capabilities
field.
- `forceLogout=bool` (=false, or true when renaming) Optionally clears
any current login info for the current user, which will invalidate
any active session. Requires 'a' or 's' privileges. Intended to be
used when disabling a user account, to ensure that any open session
is invalidated. When a user is renamed this option is implied (and
cannot be disabled) because renaming invalidates any currently
stored auth token (because the old name is part of the hash
equation).
Fields which are not provided in the request will not be modified.
Non-admin/setup users cannot edit other users and may only change their
own data if they have the 'p' (password) privilege.
As of 20120217, users who do not have the setup privilege may neither
change the setup privilege for any user nor edit another user who has
that privilege. That is, only users with setup access may propagate or
remove setup status and accounts with the setup privilege may only be
edited by themselves and other setup users.
**Response payload:** Same as user/get, using the new/saved state of the
modified user.
Example usage from the command line:
```console
$ fossil json user save --name drh --password sqlite3 \
--capabilities "as" --info "DRH"
$ fossil json user save --uid 1 --name richard \
--password fossil \
--info "Previously known as drh"
```
**Warnings:**
- When creating a new user or renaming a user, if no (new) password is
specified in the save request then the user will not be able to log
in because the previous password (for existing users) is hashed
against the old name.
- Renaming a user invalidates any active login token because his old
name is a part of the hash. i.e. the user must log back in with the
new name after being renamed.
**TODOs:**
- Login group support.

# Version (a.k.a. HAI)
**Status:** implemented
**Required privileges:** none
**Requests:**
- `/json/version`
- `/json/HAI` (alias borrowed from LOLCATZ jargon)
**Response payload example:**
```json
{
"manifestUuid":"20ff808f9809541d2eca6c49a17d5cbd16e1b93f",
"manifestVersion":"[20ff808f98]",

"manifestYear":"2011",
"releaseVersion":"1.19",
"releaseVersionNumber":119,
"jsonApiVersion": "YYYYMMDD" // added 20120409
}
```
Those particular payload fields were chosen only because they're defined
in `VERSION.h`. We may want to add other information, but nothing comes to
mind at this time.

# Page List
Returns a list of all pages, not including their content (which can be
arbitrarily large).
**Status:** implemented 201109xx
**Required privileges:** "j" or "o"
**Request:** `/json/wiki/list`
**Options:**
- `bool verbose` (=false) Changes the results to return much more
information. Added 20120219.
- `glob=wildcard` string (default=`*`). If set, only page names
matching the given wildcard are returned. Added 20120325.\
CLI: `--glob|-g STRING`
- `like=SQL LIKE string` (default=`%`). If set, only page names matching
the given SQL LIKE string are returned. Note that this match is
case-INsensitive. If both glob and like are given then only one will
work and which one takes precedence is unspecified. Added 20120325.\
CLI: `--like|-l STRING`
- `invert=bool` (default=false). If set to a true value, the glob/like
filter has a reverse meaning (pages *not* matching the wildcard are
returned). Added 20120329.\
CLI: `-i/--invert`
**Response payload: format depends on "verbose" option**
Non-verbose mode:
```json
["PageName1",..."PageNameN"]
```
In verbose mode:
```json
[{
"name":"Apache On Windows XP",
"uuid":"a7e68df71b95d35321b9d9aeec3c8068f991926c",
"user":"jeffrimko",
"timestamp":1310227825,
"size":793 /* in bytes */
},...]
```
The verbose-mode output is the same as the [`/json/wiki/get`](#get) output, but
without the content. The size property of each reflects the *byte*
length of the raw (non-HTMLized) page content.
**Potential TODOs:**
- Allow specifying (in the request) a list/array of names, as opposed
to listing all pages. The page count is rarely very high, though, so
an "overload" is very unlikely. (i have one wiki with about 47 pages
in it.)
<a id="get"></a>
# Fetch a Page
Fetches a single wiki page, including content and significant metadata.
**Status:** implemented 20110922, but response format may change.
**Required privileges:** "j" or "o"
**Request:**
- GET: `/json/wiki/get?name=PageName`
- GET: `/json/wiki/get/PageName`
- POST: `/json/wiki/get` with page name as `POST.payload` or
`POST.payload.name`.
**Response payload example:**
```json
{
"name": "Fossil",
"uuid": "...hex string...",
"parent": "uuid of parent (not set for first version of page)",
"user": "anonymous",
"timestamp": 1286143975,
"size": 1906, /* In bytes, not UTF8 characters!
Affected by format option! */
"content": "..."
}
```
**FIXME:** it's missing the mimetype (that support was added to fossil
after this was implemented).
If given no page to load, or if asked to get a page which does not
exist, an error response is generated (a usage- or resource-not-found
error, respectively).
**Options (via CLI/GET/`POST.payload`):**
- `name=string`. The page to fetch. The latest version is fetched
unless the uuid paramter is supplied (in which case name is ignored). \
CLI: `--name|-n string`\
Optionally, the name may be the 4th positional argument/request path element.
- `uuid=string`. Fetches a specific version. The name parameter is
ignored when this is specified.\
CLI: `--uid|-u string`
- `format=string ("raw"|"html"|"none")` (default="raw"). Specifies the
format of the "content" payload value.\
CLI: `--format|-f string` \
The "none" format means to return no content. In that case the size
refers to the same size as the "raw" format.
**TODOs:**
- Support passing an array of names in the request (and change
response to return an array).
<a id="create-save"></a>
# Create or Save Page
**Status:** implemented 20110922.
**Required privileges:** "k" (save) or "f" (create)
**Request:**
- `/json/wiki/create`
- `/json/wiki/save`
These work only in HTTP mode, not CLI mode. (FIXME: now that we can
simulate POST from a file, these could be used in CLI mode.)
The semantic differences between save and create are:
- Save will fail if the page doesn't already exist whereas create will
fail if it does. The createIfNotExists option (described below) can
be used to create new pages using the save operation.
- The content property is optional for the create request, whereas it
is required to be a string for save requests (but it *may* be an
empty string). This requirement for save is *almost* arbitrary, and
is intended to prevent accidental erasing of existing page content
via API misuse.
**Response payload example:**
The same as for [`/json/wiki/get`](#get) but the page content is not
included in the response (only the metadata).
**Request options** (via GET or `POST.payload` object):
- `name=string` specifies the page name.
- `content=string` is the body text.\
Content is required for save (unless `createIfNotExists` is true *and*
the page does not exist), optional for create. It *may* be an empty
string.
- `mimetype=string` specifies the mimetype for the body, noting any any
unrecognized/unsupported mimetype is silently treated as
`text/x-fossil-wiki`.
- Save (not create) supports a `createIfNotExists` boolean option which
makes it a functional superset of the create/save features. i.e. it
will create if needed, else it will update. If createIfNotExists is
false (the default) then save will fail if given a page name which
does not refer to an existing page.
- **TODO:** add `commitMessage` string property. The fossil internals
don't have a way to do this at the moment (they can as of late 2019).
Since fossil wiki commits have always had the same default commit message, this is not a
high-priority addition. See:\
[](/doc/trunk/www/fileformat.wiki#wikichng)
- **Potential TODO:** we *could* optionally also support
multi-page saving using an array of pages in the request payload:\
`[… page objects … ]`
<a id="diffs"></a>
# Wiki Diffs
**Status:** implemented 20120304
**Required privileges:** "h"
**Request:**
- `/json/wiki/diff[/version1_UUID/version2_UUID]`
**Response payload example:**
```json
{
"v1":"e32ccdcda59e930c77c1e01cebace5d71253f621",
"v2":"e15992f475760cdf3a9564d8f88cacb659ab4b07",
"diff":"@@ -1,4 +1,9 @@...<SNIP>..."
}
```
**Options:**
- `v1=uuid` and `v2=uuid` specify the two versions to diff, and are
required parameters. They may optionally be specified as the two
URL/CLI parameters following the "diff" sub-command/path.
This command does not verify that both UUIDs actually refer to the same
page name, but do verify that they refer to wiki content.
Trivia: passing the same UUIDs to the `/json/diff` command will produce
very different results - that one diffs the manifests of the commits.
**TODOs:**
- Add options for changing the format of the diff, e.g. side-by-side
and enabling the HTML markup supported by the main fossil HTML GUI.
- Potentially do a name comparison to verify that the diff is against
the same page. That said, when "renaming" pages it might be useful
to diff two different pages.
<a id="preview"></a>
# Preview
**Status:** implemented 20120310
**Required privileges:** "k" (to limit its use to only those who can
edit wiki pages). This limitation is up for debate/reconsideration.
**Request:**
- `/json/wiki/preview`
This command wiki-processes arbitrary text sent from the client. To help
curb potential abuse, its use is restricted to those with "k" access
rights.
The `POST.payload` property must be either:
1) A string containing Fossil wiki markup.
2) An Object with a `body` property holding the text to render and a
`mimetype` property describing the wiki format:
`text/x-fossil-wiki` (the default), `text/x-markdown`, or
`text/plain`. Any unknown type is treated as `text/x-fossil-wiki`.
The response payload is a string containing the rendered page. Whether
or not "all HTML" is allowed depends on site-level configuration
options, and that changes how the input is processed.
Note that the links in the generated page are for the HTML interface,
and will not work as-is for arbitrary JSON clients. In order to
integrate the parsed content with JSON-based clients the HTML will
probably need to be post-processed, e.g. using jQuery to fish out the
links and re-map wiki page links to a JSON-capable page handler.
<a id="todo"></a>
# Notes and TODOs
- When server-parsing the wiki content, the generated
intra-wiki/intra-site links will only be useful in the context of
the original fossil UI (or a work-alike), not arbitrary JSON
client apps.
Potential TODOs:
- `/wiki/history` analog to the [](/whistory) page.

# JSON Property Naming
Since most JSON usage conventionally happens in JavaScript
environments, this API has (without an explicit decision ever having
been made) adopted the ubiquitous JavaScript convention of
`camelCaseWithStartingLower` for naming properties in JSON objects.
<a id="http-get"></a>
# HTTP GET Requests
Many (if not most) requests can be made via simple GET requests, e.g. we
*could* use any of the following patterns for a hypothetical JSON-format
timeline:
- `https://..../timeline/json`
- `/timeline?format=json`
- `/timeline?json=1`
- `/timeline.json`
- `/json/timeline?...options...`
The API settled on the `/json/...` convention, primarily because it
simplifies dispatching and argument-handling logic compared to the
`/[.../]foo.json` approach. Using `/json/...` allows us to unify that
logic for all JSON sub-commands, for both CLI and HTTP modes.
<a id="http-post"></a>
# HTTP Post Requests
Certain requests, mainly things like editing checkin messages and
committing new files entirely, require POST data. This is fundamentally
very simple to do - clients post plain/unencoded JSON using a common
wrapper envelope which contains the request-specific data to submit as
well as some request-independent information (like authentication data).
<a id="request-envelope"></a>
## POST Request Envelope
POST requests are sent to the same URL as their GET counterpart (if any,
else their own path), and are sent as plain-text/unencoded JSON wrapped
in a common request envelope with the following properties:
- `requestId`: Optional arbitrary JSON value, not used by fossil, but
returned as-is in responses.
- `command`: Provides a secondary mechanism for specifying which JSON
command should be run. A request path of /json/foo/bar is equivalent
to a request with path=/json and command=foo/bar. Note that subpaths
do not work this way. e.g. path=/json/foo, command=bar will not
work, but path=/json, command=foo/bar will. This option is
particularly useful when generating JSON for piping in to CLI mode,
but it also has some response-dispatching uses on the client side.
- `authToken`: Authentication token. Created by a login
request. Determines what access rights the user has, and any given
request may require specific rights. In principle this is required
by any request which needs non-guest privileges, but cookie-aware
clients do not manually need to track this (it is managed as a
cookie by the agent/browser).
- Note that when accessing fossil over a local server instance
which was started with the `--localauth` flag, the `authToken`
will be ignored and need not be sent with any requests. The user
will automatically be given full privileges, as if they were
using CLI mode.
- `payload`: Command-specific parameters. Most can optionally come in
via GET parameters, but those taking complex structures expect them
to be placed here.
- `indent`: Optionally specifies indentation for the output. 0=no
indention. 1=a single TAB character for each level of
indentation. >1 means that many spaces per level. e.g. indent=7
means to indent 7 spaces per object/array depth level. cson also
supports other flags for fine-tuning the output spacing, and adding
them to this interface might be interesting at some
point. e.g. whether or not to add a newline to the output. CLI mode
adds extra indentation by default, whereas CGI/server modes produce
unindented output by default.
- `jsonp`: Optional String (client function name). Requests which
include this will be returned with `Content-Type
application/javascript` and will be wrapped up in a function call
using the given name. e.g. if `jsonp=foo` then the result would look like:\
`foo( {...the response envelope...} )`
The API allows most of those (normally all but the payload) to come in
as either GET parameters or properties of the top-level POSTed request
JSON envelope, with GET taking priority over POST. (Reminder to self: we
could potentially also use values from cookies. Fossil currently only
uses 1 cookie (the login token), and I'd prefer to keep it that way.)
POST requests without such an envelope will be rejected, generating a
Fossil/JSON error response (as opposed to an HTTP error response). GET
requests, by definition, never have an envelope.
POSTed client requests *must* send a Content-Type header of either
`application/json` , `application/javascript`, or `text/plain`, or the
JSON-handling code will never see the POST data. The POST handler
optimistically assumes that type `text/plain` "might be JSON", since
`application/json` is a newer convention which many existing clients
do not use (as of the time these docs were written, back in 2011).
## POST Envelope vs. `POST.payload`
When this document refers to POST data, it is referring to top-level
object in JSON-format POSTed input data. When we say `POST.payload` we
refer to the "payload" property of the POST data. While fossil's core
handles *form-urlencoded* POST data, if such data is sent in then
parsing it as JSON cannot succeed, which means that (at worst) the
JSON-mode bits will "not see" any POST data. Data POSTed to the JSON API
must be sent non-form-urlencoded (i.e. as plain text).
Framework-level configuration options are always set via the top-level
POST envelope object or GET parameters. Request-specific options are set
either in `POST.payload` or GET parameters (though the former is required
in some cases). Here is an example which demonstrates the possibly
not-so-obvious difference between the two types of options (framework
vs. request-specific):
```json
{
"requestId":"my request", // standard envelope property (optional)
"command": "timeline/wiki", // also standard
"indent":2, // output indention is a framework-level option
"payload":{ // *anything* in the payload is request-specific
"limit":1
}
}
```
When a given parameter is set in two places, e.g. GET and POST, or
POST-from-a-file and CLI parameters, which one takes precedence
depends on the concrete command handler (and may be unspecified). Most
will give precedence to CLI and GET parameters, but POSTed values are
technically preferred for non-string data because no additional "type
guessing" or string-to-whatever conversion has to be made (GET/CLI
parameters are *always* strings, even if they look like a number or
boolean).
<a id="request-param-types"></a>
# Request Parameter Data Types
When parameters are sent in the form of GET or CLI arguments, they are
inherently strings. When they come in from JSON they keep their full
type (boolean, number, etc.). All parameters in this API specify what
*type* (or types) they must (or may) be. For strings, there is no
internal conversion/interpretation needed for GET- or CLI-provided
parameters, but for other types we sometimes have to convert strings to
other atomic types. This section describes how those string-to-whatever
conversions behave.
No higher-level constructs, e.g. JSON **arrays** or **objects**, are
accepted in string form. Such parameters must be set in the POST
envelope or payload, as specified by the specific API.
This API does not currently use any **floating-point** parameters, but
does return floating-point results in a couple of places.
For **integer** parameters we use a conventional string-to-int algorithm
and assume base 10 (analog to atoi(3)). The API may err on the side of
usability when given technically invalid values. e.g. "123abc" will
likely be interpreted as the integer 123. No APIs currently rely on
integer parameters with more than 32 bits (signedness is call-dependent
but few, if any, use negative values).
**Boolean** parameters are a bit schizophrenic...
In **CLI mode**, boolean flags do not have a value, per se, and thus
require no string-to-bool conversion. e.g.
`fossil foo -aBoolOpt -non-bool-opt value`.
Those which arrive as strings via **GET parameters** treat any of the
following as true: a string starting with a character in the set
`[1-9tT]`. All other string values are considered to be false for this
purpose.
Those which are part of the **POST data** are normally (but not always -
it depends on the exact context) evaluated as the equivalent of
JavaScript booleans. e.g. if we have `POST.envelope.foo="f"`, and evaluate
it as a JSON boolean (as opposed to a string-to-bool conversion), the
result will be true because the underlying JSON API follows JavaScript
semantics for any-type-to-bool conversions. As long as clients always
send "proper" booleans in their POST data, the difference between
GET/CLI-provided booleans should never concern them.
TODO: consider changing the GET-value-to-bool semantics to match the JS
semantics, for consistency (within the JSON API at least, but that might
cause inconsistencies vis-a-vis the HTML interface).
<a id="response-envelope"></a>
# Response Envelope
Every response comes in the form of an HTTP response or (in CLI mode)
JSON sent to stdout. The body of the response is a JSON object following
a common envelope format. The envelope has the following properties:
- `fossil`: Fossil server version string. This property is basically
"the official response envelope marker" - if it is set, clients can
"probably safely assume" that the object indeed came from one of the
Fossil/JSON APIs. This API never creates responses which do not
contain this property.
- `requestId`: Only set if the request contained it, and then it is
echoed back to the caller as-is. This can be used to determine
(client-side) which request a given response is coming in for
(assuming multiple asynchronous requests are pending). In practice
this generally isn’t needed because response handling tends to be
done by closures associated with the original request object (at
least in JavaScript code). In languages without closures it might
have some use. It may be any legal JSON value - it need not be
confined to a string or number.
- `resultCode`: Standardized result code string in the form
`FOSSIL-####`. Only error responses contain a `resultCode`.
- `resultText`: Possibly a descriptive string, possibly
empty. Supplements the resultCode, but can also be set on success
responses (but normally isn't). Clients must not rely on any
specific values being set here.
- `payload`: Request-specific response payload (data type/structure is
request-specific). The payload is never set for error responses,
only for success responses (and only those which actually have a
payload - not all do).
- `timestamp`: Response timestamp (GMT Unix Epoch). We use seconds
precision because I did not know at the time that Fossil actually
records millisecond precision.
- `payloadVersion`: Not initially needed, but reserved for future use
in maintaining version compatibility when the format of a given
response type's payload changes. If needed, the "first version"
value is assumed to be 0, for semantic [near-]compatibility with the
undefined value clients see when this property is not set.
- `command`: Normalized form of the command being run. It consists of
the "command" (non-argument) parts of the request path (or CLI
positional arguments), excluding the initial "/json/" part. e.g. the
"command" part of "/json/timeline/checkin?a=b" (CLI: json timeline
checkin...) is "timeline/checkin" (both in CLI and HTTP modes).
- `apiVersion`: Not yet used, but reserved for a numeric value which
represents the JSON API's version (which can be used to determine if
it has a given feature or not). This will not be implemented until
it's needed.
- `warnings`: Reserved for future use as a standard place to put
non-fatal warnings in responses. Will be an array but the warning
structure/type is not yet specified. Intended primarily as a
debugging tool, and will "probably not" become part of the public
client interface.
- `g`: Fossil administrators (those with the "a" or "s" permissions)
may set the `debugFossilG` boolean request parameter (CLI:
`--json-debug-g`) to enable this property for any given response. It
contains a good deal of the server-side internal state at the time
the response was generated, which is often useful in debuggering
problems. Trivia: it is called "g" because that's the name of
fossil's internal global state object.
- `procTimeMs`: For debugging only - generic clients must not rely on
this property. Contains the number of milliseconds the JSON command
processor needed to dispatch and process the command. TODO: move the
timer into the fossil core so that we can generically time its
responses and include the startup overhead in the time calculation.
<a id="http-response-header"></a>
# HTTP Response Headers
The Content-Type HTTP header of a response will be either
application/json, application/javascript, or text/plain, depending on
whether or not we are in JSONP mode or (failing that) the contents of
the "Accept" header sent in the request. The response type will be
text/plain if it cannot figure out what to do. The response's
Content-Type header *may* contain additional metadata, e.g. it might
look like: application/json; charset=utf-8
Apropos UTF-8: note that JSON is, by definition, Unicode and recommends
UTF-8 encoding (which is what we use). That means if your console cannot
handle UTF-8 then using this API in CLI mode might (depending on the
content) render garbage on your screen.
<a id="cli-vs-http"></a>
# CLI vs. HTTP Mode
CLI (command-line interface) and HTTP modes (CGI and standalone server)
are consolidated in the same implementations and behave essentially
identically, with only minor exceptions.
An HTTP path of `/json/foo` translates to the CLI command `fossil json
foo`. CLI mode takes options in the fossil-convention forms (e.g. `--foo 3`
or `-f 3`) whereas HTTP mode takes them via GET/POST data (e.g. `?foo=1`).
(Note that per long-standing fossil convention CLI parameters taking a
value do not use an equal sign before the value!)
For example:
- HTTP: `/json/timeline/wiki?after=2011-09-01&limit=3`
- CLI: `fossil json timeline wiki --after 2011-09-01 --limit 3`
Some commands may only work in one mode or the other (for various
reasons). In CLI mode the user automatically has full setup/admin
access.
In HTTP mode, request-specific options can also be specified in the
`POST.payload` data, and doing so actually has an advantage over
specifying them as URL parameters: posting JSON data retains the full
type information of the values, whereas GET-style parameters are always
strings and must be explicitly type-checked/converted (which may produce
unpredictable results when given invalid input). That said, oftentimes
it is more convenient to pass the options via URL parameters, rather
than generate the request envelope and payload required by POST
requests, and the JSON API makes some extra effort to treat GET-style
parameters type-equivalent to their POST counterparts. If a property
appears in both GET and `POST.payload`, GET-style parameters *typically*
take precedence over `POST.payload` by long-standing convention (=="PHP
does it this way by default").
(That is, however, subject to eventual reversal because of the
stronger type safety provided by POSTed JSON. Philosophically
speaking, though, GET *should* take precedence, in the same way that
CLI-provided options conventionally override app-configuration-level
options.)
One notable functional difference between CLI and HTTP modes is that in
CLI mode error responses *might* be accompanied by a non-0 exit status
(they "should" always be, but there might be cases where that does not
yet happen) whereas in HTTP mode we always try to exit with code 0 to
avoid generating an HTTP 500 ("internal server error"), which could keep
the JSON response from being delivered. The JSON code only intentionally
allows an HTTP 500 when there is a serious internal error like
allocation or assertion failure. HTTP clients are expected to catch
errors by evaluating the response object, not the HTTP result code.
<a id="simulating-post-data"></a>
# Simulating POSTed data
We have a mechanism to feed request data to CLI mode via
files (simulating POSTed data), as demonstrated in this example:
```console
$ cat in.json
{ "command": "timeline/wiki", "indent":2, "payload":{"limit":1}}
$ fossil json --json-input in.json # use filename - for stdin
```
The above is equivalent to:
```console
$ echo '{"indent":2, "payload":{"limit":1}}' \
| fossil json timeline wiki --json-input -
```
Note that the "command" JSON parameter is only checked when no json
subcommand is provided on the CLI or via the HTTP request path. Thus we
cannot pass the CLI args "json timeline" in conjunction with a "command"
string of "wiki" this way.
***HOWEVER...***
Much of the existing JSON code was written before the `--json-input`
option was possible. Because of this, there might be some
"misinteractions" when providing request-specific options via *both*
CLI options and simulated POST data. Those cases will eventually be
ironed out (with CLI options taking precedence). Until then, when
"POSTing" data in CLI mode, for consistent/predictible results always
provide any options via the JSON request data, not CLI arguments. That
said, there "should not" be any blatant incompatibilities, but some
routines will prefer `POST.payload` over CLI/GET arguments, so there
are some minor inconsistencies across various commands with regards to
which source (POST/GET/CLI) takes precedence for a given option. The
precedence "should always be the same," but currently cannot be due to
core fossil implementation details (the internal consolidation of
GET/CLI/POST vars into a single set).
<a id="json-indentation"></a>
# Indentation/Formatting of JSON Output
CLI mode accepts the `--indent|-I #` option to set the indention level
and HTTP mode accepts `indent=#` as a GET/POST parameter. The semantics
of the indention level are derived from the underlying JSON library and
have the following meanings: 0 (zero) or less disables all superfluous
indentation (this is the default in HTTP mode). A value of 1 uses 1 hard
TAB character (ASCII 0x09) per level of indention (the default in CLI
mode). Values greater than 1 use that many whitespaces (ASCII 32d) per
level of indention. e.g. a value of 7 uses 7 spaces per level of
indention. There is no way to specify one whitespace per level, but if
you *really* want one whitespace instead of one tab (same data size) you
can filter the output to globally replace ASCII 9dec (TAB) with ASCII
32dec (space). Because JSON string values *never* contain hard tabs
(they are represented by `\t`) there is no chance that such a global
replacement will corrupt JSON string contents - only the formatting will
be affected.
Potential TODO: because extraneous indention "could potentially" be used
as a form of DoS, the option *might* be subject to later removal from HTTP
mode (in CLI it's fine).
In HTTP mode no trailing newline is added to the output, whereas in CLI
mode one is normally appended (exception: in JSONP mode no newline is
appended, to (rather pedantically and arbitraily) allow the client to
add a semicolon at the end if he likes). There is currently no option to
control the newline behaviour, but the underlying JSON code supports
this option, so adding it to this API is just a matter of adding the
CLI/HTTP args for it.
Pedantic note: internally the indention level is stored as a single
byte, so giving large indention values will cause harmless numeric
overflow (with only cosmetic effects), meaning, e.g., 257 will overflow
to the value 1.
Potential TODO: consider changing cson's indention mechanism to use a
*signed* number, using negative values for tabs and positive for
whitespace count (or the other way around). This would require more
doc changes than code changes :/.
<a id="jsonp"></a>
# JSONP
The API supports JSONP-style output. The caller specifies the callback
name and the JSON response will be wrapped in a function call to that
name. For HTTP mode pass the `jsonp=string` option (via GET or POST
envelope) and for CLI use `--jsonp string`.
For example, if we pass the JSONP name `myCallback` then a response will
look like:
```js
myCallback({...response...})
```
Note that fossil does not evaluate the callback name itself, other than
to verify that it is-a string, so "garbage in, garbage out," and all
that. (Remember that CLI and GET parameters are *always* strings, even
if they *look* like numbers.)
<a id="result-codes"></a>
# API Result Codes
Result codes are strings which tell the client whether or not a given
API call succeeded or failed, and if it failed *perhaps* some hint as to
why it failed.
The result code is available via the resultCode property of every
*error* response envelope. Since having a result code value for success
responses is somewhat redundant, success responses contain no resultCode
property. In practice this simplifies error checking on the client side.
The codes are strings in the form `FOSSIL-####`, where `####` is a
4-digit integral number, left-padded with zeros. The numbers follow
these conventions:
- The number 0000 is reserved for the "not an error" (OK) case. Since
success responses do not contain a result code, clients won't see
this value (except in documentation).
- All numbers with a leading 0 are reserved for *potential* future use
in reporting non-fatal warnings.
- Despite *possibly* having leading zeros, the numbers are decimal,
not octal. Script code which uses eval() or similar to produce
integers from them may need to take that into account.
- The 1000ths and 100ths places of the number describe the general
category of the error, e.g. authentication- vs. database- vs. usage
errors. The 100ths place is more specific than the 1000ths place,
allowing two levels of sub-categorization (which "should be enough"
for this purpose). This separation allows the server administrator
to configure the level of granularity of error reporting. e.g. some
admins consider error messages to be security-relevant and like to
"dumb them down" on their way to the client, whereas developers
normally want to see very specific error codes when tracking down a
problem. We can offer a configuration option to "dumb down" error
codes to their generic category by simply doing a modulo 100
(or 1000) against the native error code number. e.g. FOSSIL-1271
could (via a simple modulo) be reduced to FOSSIL-1200 or
FOSSIL-1000, depending on the paranoia level of the sysadmin. I have
tried to order the result code numbers so that a dumb-down level of
2 provides reasonably usable results without giving away too much
detail to malicious clients.\
(**TODO:** `g.json.errorDetailParanoia` is used to set the
default dumb-down level, but it is currently set at compile-time.
It needs to be moved to a config option. We have a chicken/egg scenario
with error reporting and db access there (where the config is
stored).)
- Once a number is assigned to a given error condition (and actually
used somewhere), it may not be changed/redefined. JSON clients need
to be able to rely on stable result codes in order to provide
adequate error reporting to their clients, and possibly for some
error recovery logic as well (i.e. to decide whether to abort or
retry).
The *tentative* list of result codes is shown in the following table.
These numbers/ranges are "nearly arbitrarily" chosen except for the
"special" value 0000.
**Maintenance reminder:** these codes are defined in
[`src/json_detail.h`](/finfo/src/json_detail.h) (enum
`FossilJsonCodes`) and assigned default `resultText` values in
[`src/json.c:json_err_cstr()`](/finfo/src/json.c). Changes there need
to be reflected here (and vice versa). Also, we have assertions in
place to ensure that C-side codes are in the range 1000-9999, so do
not just go blindly change the numeric ranges used by the enum.
**`FOSSIL-0###`: Non-error Category**
- `FOSSIL-0000`: Success/not an error. Succesful responses do not
contain a resultCode, so clients should never see this.
- `FOSSIL-0###`: Reserved for potential future use in reporting
non-fatal warnings.
**`FOSSIL-1000`: Generic Errors Category**
- `FOSSIL-1101`: Invalid request. Request envelope is invalid or
missing.
- `FOSSIL-1102`: Unknown JSON command.
- `FOSSIL-1103`: Unknown/unspecified error
- `FOSSIL-1104`: RE-USE
- `FOSSIL-1105`: A server-side timeout was reached. (i’m not sure we
can actually implement this one, though.)
- `FOSSIL-1106`: Assertion failed (or would have had we
continued). Note: if an `assert()` fails in CGI/server modes, the HTTP
response will be code 500 (Internal Server Error). We want to avoid
that and return a JSON response instead. All of that said - there seems
to be little reason to implement this, since assertions are "truly
serious" errors.
- `FOSSIL-1107`: Allocation/out of memory error. This cannot be reasonably
reported because fossil aborts if an allocation fails.
- `FOSSIL-1108`: Requested API is not yet implemented.
- `FOSSIL-1109`: Panic! Fossil's `fossil_panic()` or `cgi_panic()` was
called. In non-JSON HTML mode this produces an HTTP 500
error. Clients "should" report this as a potential bug, as it
"possibly" indicates that the C code has incorrect argument- or
error handling somewhere.
- `FOSSIL-1110`: Reading of artifact manifest failed. Time to contact
your local fossil guru.
- `FOSSIL-1111`: Opening of file failed (e.g. POST data provided to
CLI mode).
**`FOSSIL-2000`: Authentication/Access Error Category**
- `FOSSIL-2001`: Privileged request was missing authentication
token/cookie.
- `FOSSIL-2002`: Access to requested resource was denied. Oftentimes
the `resultText` property will contain a human-language description of
the access rights needed for the given command.
- `FOSSIL-2003`: Requested command is not available in the current
operating mode. Returned in CLI mode by commands which require HTTP
mode (e.g. login), and vice versa. FIXME: now that we can simulate
POST in CLI mode, we can get rid of this distinction for some of the
commands.
- `FOSSIL-2100`: Login Failed.
- `FOSSIL-2101`: Anonymous login attempt is missing the
"anonymousSeed" property (fetched via [the `/json/anonymousPassword`
request](api-auth.md#login-anonymous)). Note that this is more
specific form of `FOSSIL-3002`.
ONLY FOR TESTING purposes should the remaning 210X sub-codes be
enabled (they are potentially security-relevant, in that the client
knows which part of the request was valid/invalid):
- `FOSSIL-2102`: Name not supplied in login request
- `FOSSIL-2103`: Password not supplied in login request
- `FOSSIL-2104`: No name/password match found
**`FOSSIL-3000`: Usage Error Category**
- `FOSSIL-3001`: Invalid argument/parameter type(s) or value(s) in
request
- `FOSSIL-3002`: Required argument(s)/parameter(s) missing from
request
- `FOSSIL-3003`: Requested resource identifier is ambiguous (e.g. a
shortened hash that matches multiple artifacts, an abbreviated
date that matches multiple commits, etc.)
- `FOSSIL-3004`: Unresolved resource identifier. A branch/tag/uuid
provided by client code could not be resolved. This is a special
case of #3006.
- `FOSSIL-3005`: Resource already exists and overwriting/replacing is
not allowed. e.g. trying to create a wiki page or user which already
exists. FIXME? Consolidate this and resource-not-found into a
separate category for dumb-down purposes?
- `FOSSIL-3006`: Requested resource not found. e.g artifact ID, branch
name, etc.
**`FOSSIL-4000`: Database-related Error Category**
- `FOSSIL-4001`: Statement preparation failed.
- `FOSSIL-4002`: Parameter binding failed.
- `FOSSIL-4003`: Statement execution failed.
- `FOSSIL-4004`: Database locked (this is not used anywhere, but
reserved for future use).
Special-case DB-related errors...
- `FOSSIL-4101`: Fossil Schema out of date (repo rebuild required).
- `FOSSIL-4102`: Fossil repo db could not be found.
- `FOSSIL-4103`: Repository db is not valid (possibly corrupt).
- `FOSSIL-4104`: Check-out not found. This is similar to FOSSIL-4102
but indicates that a local checkout is required (but was not
found). Note that the 4102 gets triggered earlier than this one, and
so can appear in cases when a user might otherwise expect a 4104
error.
Some of those error codes are of course "too detailed" for the client to
do anything with (e.g.. 4001-4004), but their intention is to make it
easier for Fossil developers to (A) track down problems and (B) support
clients who report problems. If a client reports, "I get a FOSSIL-4000,
how can I fix it?" then the developers/support personnel can't say much
unless they know if it's a 4001, 4002, 4003, 4004, or 4101 (in which
case they can probably zero in on the problem fairly quickly, since they
know which API call triggered it and they know (from the error code) the
general source of the problem).
## Why Standard/Immutable Result Codes are Important
- They are easily internationalized (i.e. associated with non-English
error text)
- Clients may be able to add automatic retry strategies for certain
problem types by examining the result code. e.g. if fossil returns a
locking or timeout error \[it currently does no special
timeout/locking handling, by the way\] the client could re-try,
whereas a usage error cannot be sensibly retried with the same
inputs.
- The "category" structure described above allows us some degree of
flexibility in how detailed the reported errors are reported.
- While the string prefix "FOSSIL-" on the error codes may seem
superfluous, it has one minor *potential* advantage on the client
side: when managing several unrelated data sources, these error
codes can be immediately identified (by higher-level code which may
be ignorant of the data source) as having come from the fossil API.
Think "ORA-111" vs. "111".

# Before Committing Changes...
Because this code lives in the trunk, there are certain
guidelines which must be followed before committing any changes:
1. Read the [checkin preparation list](/doc/trunk/www/checkin.wiki).
2. Changes to the files `src/json_*.*`, and its related support code
(e.g. `ajax/*.*`), may be made freely without affecting mainline
users. Changes to other files, unless they are trivial or made for
purposes outside the JSON API (e.g. an unrelated bug fix), must be
reviewed carefully before committing. When in doubt, create a branch
and post a request for a review.
3. The Golden Rule is: *do not break the trunk build*.
<a id="json-c-api"></a>
# JSON C API
libcson, the underlying JSON API, is a separate project, included in
fossil in "amalgamation" form: see `extsrc/cson_amalgamation.[ch]`. It has
thorough API docs and a good deal of information is in its wiki:
[](https://fossil.wanderinghorse.net/wikis/cson/)
In particular:
[](https://fossil.wanderinghorse.net/wikis/cson/?page=CsonArchitecture)
gives an overview of its architecture. Occasionally new versions of it
are pulled into the Fossil tree, but other developers generally need not
concern themselves with that.
(Trivia: the cson wiki's back-end is fossil using this very JSON API,
living on top of a custom JavaScript+HTML5 application.)
Only a small handful of low-level fossil routines actually input or
output JSON text (only for reading in POST data and sending the
response). In the C code we work with the higher-level JSON value
abstractions provided by cson (conceptually similar to an XML DOM). All
of the JSON-defined data types are supported, and we can construct JSON
output of near arbitrary complexity with the caveat that *cyclic data
structures are strictly forbidden*, and *will* cause memory corruption,
crashes, double free()'s, or other undefined behaviour. Because JSON
cannot, without client-specific semantic extensions to JSON, represent
cyclic structures, it is not anticipated that this will be a
problem/limitation when generating output for fossil.
<a id="json-commands"></a>
# Architecture of JSON Commands
In order to consolidate CLI/HTTP modes for JSON handling, this code
foregoes fossil's conventional command/path dispatching mechanism. Only
the top-most "json" command/path is dispatched directly by fossil's
core. The disadvantages of this are that we lose fossil's conventional
help text mechanism (which is based on code comments in the
command/path's dispatcher impl) and the ability to write abbreviated
command names in CLI mode ("json" itself may be abbreviated, but not the
subcommands). The advantages are that we can handle CLI/HTTP modes
almost identically (there are a couple of minor differences) by unifying
them under the same callback functions much more easily.
The top-level "json" command/path uses its own dispatching mechanism
which uses either the path (in HTTP mode) or CLI positional arguments to
dispatch commands (stopping at the first "flag option" (e.g. -foo) in
CLI mode). The command handlers are simply callback functions which
return a cson\_value pointer (the C representation of an arbitrary JSON
value), representing the "payload" of the response (or NULL - not all
responses need a payload). On error these callbacks set the internal
JSON error state (detailed in a subsection below) and return NULL. The
top-level dispatcher then creates a response envelope and returns the
"payload" from the command (if any) to the caller. If a callback sets
the error state, the top-level dispatcher takes care to set the error
information in the response envelope. In summary:
- The top-level dispatchers (`json_page_top()` and `json_cmd_top()`)
are called by fossil's core when the "json" command/path is called.
They initialize the JSON-mode global state, dispatch the requested
command, and handle the creation of the response envelope. They
prepare all the basic things which the individual subcommands need
in order to function.
- The command handlers (most are named `json_page_something()`)
implement the `fossil_json_f()` callback interface (see
[`src/json_detail.h`](/finfo/src/json_detail.h)). They are
responsible for permissions checking, setting any error state, and
passing back a payload (if needed - not all commands return a
payload). It is strictly forbidden for these callbacks to produce
any output on stdout/stderr, and doing so effectively corrupts the
out-bound JSON and HTTP headers.
There is a wrench in all of that, however: the vast majority of fossil's
commands "fail fast" - they will `exit()` if they encounter an error. To
handle that, the fossil core error reporting routines have been
refactored a small bit to operate differently when we are running in
JSON mode. Instead of the conventional output, they generate a JSON
error response. In HTTP mode they exit with code 0 to avoid causing an
HTTP 500 error, whereas in CLI mode they will exit with a non-0 code.
Those routines still `exit()`, as in the conventional CLI/HTTP modes, but
they will exit differently. Because of this, it is perfectly fine for a
command handler to exit via one of fossil's conventional mechanisms
(e.g. `db_prepare()` can be fatal, and callbacks may call `fossil_panic()`
if they really want to). One exception is `fossil_exit()`, which does
_not_ generate any extra output and will `exit()` the app. In the JSON
API, as a rule of thumb, `fossil_exit()` is only used when we *want* a
failed request to cause an HTTP 500 error, and it is reserved for
allocation errors and similar truly catastrophic failures. That said...
libcson has been hacked to use `fossil_alloc()` and friends for memory
management, and those routines exit on error, so alloc error handling in
the JSON command handler code can afford to be a little lax (the
majority of *potential* errors clients get from the cson API have
allocation failure as their root cause).
As a side-note: the vast majority (if not all) of the cson API calls are
"NULL-safe", meaning that will return an error code (or be a no-op) if
passed NULL arguments. e.g. the following chain of calls will not crash
if the value we're looking for does not exist, is-not-a String (see
`cson_value_get_string()` for important details), or if `myObj` is NULL:
```c
const char * str =
cson_string_cstr( // get the C-string form of a cson_string
cson_value_get_string( // get its cson_string form
cson_object_get(myObj,"foo") // search for key in an Object
)
);
```
If `"foo"` is not found in `myObj` (or if `myObj` is NULL) then v will be
NULL, as opposed to stepping on a NULL pointer somewhere in that call
chain.
Note that all cson JSON values except Arrays and Objects are *immutable*
- you cannot change a string's or number's value, for example. They also
use reference counting to manage ownership, as documented and
demonstrated on this page:
[](https://fossil.wanderinghorse.net/wikis/cson/?page=TipsAndTricks)
In short, after creating a new value you must eventually *either* add it
to a container (Object or Array) to transfer ownership *or* call
`cson_value_free()` to clean it up (exception: the Fossil/JSON command
callbacks *return* a value to transfer ownership to the dispatcher).
Sometimes it's more complex than that, but not normally. Any given value
may legally be stored in any number of containers (or multiple times
within one container), as long as *no cycles* are introduced (cycles
*will* cause undefined behaviour). Ownership is shared using reference
counting and the value will eventually be freed up when its last
remaining reference is freed (e.g. when the last container holding it is
cleaned up). For many examples of using cson in the context of fossil,
see the existing `json_page_xxx()` functions in `json_*.c`.
<a id="reporting-errors"></a>
# Reporting Errors
To report an error from a command callback, one abstractly needs to:
- Set g.json.resultCode to one of the `FSL_JSON_E_xxx` values
(defined in [`src/json_detail.h`](/finfo/src/json_detail.h)).
- *Optionally* set `g.zErrMsg` to contain the (dynamically-allocated!)
error string to be sent to the client. If no error string is set
then a standard/generic string is used for the given error code.
- Clean up any resources created so far by the handler.
- Return NULL. If it returns non-NULL, the dispatcher will destroy the
value and not include it in the error response.
That normally looks something like this:
```
if(!g.perm.Read){
json_set_err(FSL_JSON_E_DENIED, "Requires 'o' permissions.");
return NULL;
}
```
`json_set_err()` is a variadic printf-like function, and can use the
printf extensions supported by mprintf() and friends (e.g. `%Q` and `%q`)
(but they are normally not needed in the context of JSON). If the error
string is NULL or empty then `json_err_cstr(errorCode)` is used to fetch
the standard/generic error string for the given code.
When control returns to the top-level dispatching function it will check
`g.json.resultCode` and, if it is not 0, create an error response using
the `g.json.resultCode` and `g.zErrMsg` to construct the response's
`resultCode` and `resultText` properties.
If a function wants to output an error and exit by itself, as opposed
to returning to the dispatcher, then it must behave slightly
differently. See the docs for `json_err()` (in
[`src/json.c`](/finfo/src/json.c)) for details, and search that file
for various examples of its usage. It is also used by fossil's core
error-reporting APIs, e.g. `fossil_panic()` (defined in [`src/main.c`](/finfo/src/main.c)).
That said, it would be "highly unusual" for a callback to need to do
this - it is *far* simpler (and more consistent/reliable) to set the
error state and return to the dispatcher.
<a id="command-args"></a>
# Getting Command Arguments
Positional parameters can be fetched usinig `json_command_arg(N)`, where
N is the argument position, with position 0 being the "json"
command/path. In CLI mode positional arguments have their obvious
meaning. In HTTP mode the request path (or the "command" request
property) is used to build up the "command path" instead. For example:
CLI: `fossil json a b c`
HTTP: `/json/a/b/c`
HTTP POST or CLI with `--json-input`: /json with POSTed envelope
`{"command": "a/b/c" …}`
Those will have identical "command paths," and `json_command_path(2)`
would return the "b" part.
Caveat: a limitation of this support is that all CLI flags must come
*after* all *non-flag* positional arguments (e.g. file names or
subcommand names). Any argument starting with a dash ("-") is considered
by this code to be a potential "flag" argument, and all arguments after
it are ignored (because the generic handling cannot know if a flag
requires an argument, which changes how the rest of the arguments need
to be interpreted).
To get named parameters, there are several approaches (plus some special
cases). Named parameters can normally come from any of the following
sources:
- CLI arguments, e.g. `--foo bar`
- GET parameters: `/json/...?foo=bar`
- Properties of the POST envelope
- Properties of the `POST.payload` object (if any).
To try to simplify the guessing process the API has a number of
functions which behave ever so slightly differently. A summary:
- `json_getenv()` and `json_getenv_TYPE()` search the so-called "JSON
environment," which is a superset of the GET/POST/`POST.payload` (if
`POST.payload` is-a Object).
- `json_find_option_TYPE()`: searches the CLI args (only when in CLI
mode) and the JSON environment.
- The use of fossil's `P()` and `PD()` macros is discouraged in JSON
callbacks because they can only handle String data from the CLI or
GET parameters (not POST/`POST.payload`). (Note that `P()` and `PD()`
*normally* also handle POSTed keys, but they only "see" values
posted as form-urlencoded fields, and not JSON format.)
- `find_option()` (from `src/main.c`) "should" also be avoided in
JSON API handlers because it removes flag from the g.argv
arguments list. That said, the JSON API does use `find_option()` in
several of its option-finding convenience wrappers.
For example code: the existing command callbacks demonstrate all kinds
of uses and the various styles of parameter/option inspection. Check out
any of the functions named `json_page_SOMETHING()`.

# Creating JSON Data
<a href="creating-json-values"></a>
## Creating JSON Values
cson has a fairly rich API for creating and manipulating the various
JSON-defined value types. For a detailed overview and demonstration I
recommend reading:
[](https://fossil.wanderinghorse.net/wikis/cson/?page=HowTo)
That said, the Fossil/JSON API has several convenience wrappers to save
a few bytes of typing:
- `json_new_string("foo")` is easier to use than
`cson_value_new_string("foo", 3)`, and
`json_new_string_f("%s","foo")` is more flexible.
- `json_new_int()` is easier to type than `cson_value_new_integer()`.
- `cson_output_Blob()` and `cson_parse_Blob()` can write/read JSON
to/from fossil `Blob`-type objects.
It also provides several lower-level JSON features which aren't of
general utility but provide necessary functionality for some of the
framework-level code (e.g. `cson_data_dest_cgi()`), which is only used
by the deepest of the JSON internals).
<a href="query-to-json"></a>
## Converting SQL Query Results to JSON
The `cson_sqlite3_xxx()` family of functions convert `sqlite3_stmt` rows
to Arrays or Objects, or convert single columns to a JSON-compatible
form. See `json_stmt_to_array_of_obj()`,
`json_stmt_to_array_of_array()` (both in `src/json.c`), and
`cson_sqlite3_column_to_value()` and friends (in
`extsrc/cson_amalgamation.h`). They work in an intuitive way for numeric
types, but they optimistically/naively *assume* that any fields of type
TEXT or BLOB are actually UTF8 data, and treat them as such. cson's
string class only handles UTF8 data and it is semantically illegal to
feed them anything but UTF8. Violating this will likely result in
down-stream errors (e.g. when emitting the JSON string output). **The
moral of this story is:** *do not use these APIs to fetch binary data*.
JSON doesn't do binary and the `cson_string` class does not
protect itself against clients feeding it non-UTF8 data.
Here's a basic example of using these features:
```c
Stmt q = empty_Stmt;
cson_value * rows = NULL;
db_prepare(&q, "SELECT a AS a, b AS b, c AS c FROM foo");
rows = json_stmt_to_array_of_obj( &sql, NULL );
db_finalize(&q);
// side note: if db_prepare()/finalize() fail (==they exit())
// then a JSON-format error reponse will be generated.
```
On success (and if there were results), `rows` is now an Array value,
each entry of which contains an Object containing the fields (key/value
pairs) of each row. `json_stmt_to_array_of_array()` returns each row
as an Array containing the column values (with no column name
information).
**Note the seemingly superfluous use of the "AS" clause in the above
SQL.** Having them is actually significant! If a query does *not* use AS
clauses, the row names returned by the db driver *might* be different
than they appear in the query (this is documented behaviour of sqlite3).
Because the JSON API needs to return stable field names, we need to use
AS clauses to be guaranteed that the db driver will return the column
names we want. Note that the AS clause is often used to translate column
names into something more JSON-conventional or user-friendly, e.g.
"SELECT cap AS capabilities...". Alternately, we can convert the
individual `sqlite3_stmt` column values to JSON using
`cson_sqlite3_column_to_value()`, without referring directly to the
db-reported column name.

<a id="why"></a>
# Why?
In September, 2011, Fossil contributor Stephan Beal had the great
pleasure of meeting D. Richard Hipp, Fossil's author, for lunch in
Munich, Germany. During the conversation Richard asked, "what does
Fossil need next?" Stephan's first answer was, "refactoring into a
library/client, as opposed to a monolithic app." We very quickly
agreed that the effort required would be "herculean," and second
choice was voiced, "a JSON API." They briefly discussed the idea and
Richard gave his blessing. That night work began.
Why a JSON API? Because it is the next best thing to the
"librification" of Fossil, in that it makes Fossil's features
available to near-arbitrary applications using a simple, globally
available data format.
<a id="building"></a>
# Building JSON Support
In environments supported by fossil's `configure` script,
simply pass `--enable-json` to it:
```
$ ./configure --prefix=$HOME --enable-json ...
```
When built without that option, JSON support is disabled. **When
reconfiguring the source tree**, ***always be sure to do a "make
clean"*** (or equivalent for your platform) between builds (preferably
*before* reconfiguring), to ensure that everything is rebuilt properly.
If you fail to do that after enabling JSON on a tree which has already
been built, most of the sources will not be rebuilt properly. The reason
is that the JSON files are actually unconditionally compiled, but when
built without `--enable-json` they compile to empty object files. Thus
after a reconfigure the (empty) object files are still up-to-date
vis-a-vis the sources, and won't be rebuilt.
To build Fossil with JSON support on Windows using the Microsoft C
compiler:
```
cd win
nmake -f Makefile.msc FOSSIL_ENABLE_JSON=1
```
It has been seen to compile in VC versions 6 and higher.

# Goals & Non-goals
The API described here is most certainly not
[*REST*](http://en.wikipedia.org/wiki/Representational_state_transfer)-conformant,
but is instead JSON over HTTP. The error reporting techniques of the
REST conventions (using HTTP error codes) "does not mesh" with my ideas
of separation of transport- vs. app-side errors. Additionally, REST
requires HTTP methods which are not specified by CGI (namely PUT and
DELETE), which means we can't possibly implement a REST-compatible
interface on top of fossil (which uses CGI mode even for its built-in
server).
The **overall goals** of this effort include:
- A JSON-based API off of which clients can build customized Fossil
UIs and special-purpose applications. e.g. a desktop notification
applet which polls for new timeline data.
- Arbitrary JSON-using clients should be able to use it. Though JSON
originates from JavaScript, it is truly a cross-platform data format
with a very high adoption rate. (There’s even a JSON implementation
for Oracle PL/SQL.)
- Fossil’s CGI and Server modes are the main targets and should be
supported equally. CLI JSON mode is of secondary concern (but is in
practice easier to test, so it’s generally implemented first).
The ***non-goals*** include:
- We won’t be able to implement *every* feature of Fossil via a JSON
interface, and we won’t try to.
- Binary data (e.g. commits of binary files or downloading ZIP files)
is not an initial goal, but "might be interesting" once the overall
infrastructure is in place and working well. See below for more
details about binary data in JSON.
- A "pure REST" interface is seemingly not possible due to REST
relying on HTTP methods not specified in the CGI standard (PUT and
DELETE). Additionally, REST-style error reporting cannot be used by
non-HTTP clients (which this code supports).
Adding JSON support also gives us a framework off of which to
build/enhance other features. Some examples include:
- **Internationalization**. Errors are reported via standard codes and
the raw artifact data is language-independent.
- The ability to author **special-case clients**, e.g. a ticket
poller.
- Use **arbitrary HTTP-capable languages** to implement such tools.
Programming languages which can execute programs and intercept their
stdout output can use the JSON API via a local fossil binary.
- **Automatable tests.** Many of fossil's test results currently have
to be "visually reviewed" for correctness after changes (e.g.
changes in the HTML interface). JSON structures can be
programmatically checked for correctness. Artifacts are immutable,
which allows us to be very specific in what data to expect as output
(for artifact-specific requests the payload data will often (but not
always) be the same across all requests and all time).

# Potential Client-side Uses
Some of the potential client-side uses of this API include...
- Custom apps/applets to fetch timeline/ticket/etc. information from
arbitrary repositories. There are many possibilities here, including
"dashboard" sites which monitor several repositories.
- Custom post-commit triggers, by polling for changes and reacting to
them (e.g. sending mails).
- A custom wiki front-end which uses fossil as the back-end storage,
inheriting its versioning and user access support while providing a
completely custom wiki-centric UI. Such a wiki need not have, on the
surface, anything to do with fossil or source control, as fossil
would just become a glorified wiki back-end. This approach also
allows clients to serve wiki pages in a format of their choice -
since all rendering would be done client-side, they could use
whatever format they like.
<a id="considerations"></a>
# Technical Problems and Considerations
A random list of considerations which need to be made and potential
problem areas...
- **Binary data:** JSON is a text serialization method, and it takes
up the “payload†area of each HTTP request, so there is no
reasonable way to include binary data in the JSON message without
some sort of codec like Base64, for which there is no provision in
the current JSON API. You will therefore find no JSON API for
committing changes to a file in the repository, for example. Other
Fossil APIs such as [`/raw`](/help?cmd=/raw) or
[`/fileedit`](../fileedit-page.md) may serve you better.
- **64-bit integers:** The JSON standard does not specify integer precision,
because it targets many different platforms, and not all of
them can support more than 32 bits. JavaScript (from which JSON
derives) supports 53 bits of integer precision, which may affect how
a given client-side JSON implementation sends large integers to Fossil’s JSON
API. Our JSON parser can cope with integers larger than 32 bits on input, and it
can emit them, but it requires platform support. If you’re running
Fossil on a 64-bit host, you should not run into problems in
this area, but if you’re on a legacy 32-bit only or a mixed 32/64-bit
system, it’s possible that some integers in the API could be
clipped. Realize however that this is a rare case: Fossil currently
cannot store files large enough to exceed a 32-bit `size_t` value,
and `time_t` won’t roll past 32-bit integers until 2038. We’re aware
of no other uses of integers in this API that could even in
principle exceed the range of a 32-bit integer.
- **Timestamps:** For portability, this API uses UTC Unix epoch
timestamps. (`time_t`) They are the most portable time representation out
there, easily usable in most programming environments. (In
hindsight, we might better have used a higher-precision time format,
but changing that now would break API compatibility.)

<a id="content-type"></a>
# Beware of Content-Type and Encoding...
When posting data to fossil, make sure that the request sends:
- **Content-Type** of `application/json`. Fossil also (currently)
accepts `application/javascript` and `text/plain` as JSON input,
but `application/json` is preferred. The client may optionally
send `;charset=utf-8` with the Content-Type, but any other
encoding produces undefined results. Behaviour without the charset
or with `;charset=utf-8` suffix is identical.
- **POST data must be an non-form-encoded JSON string**
(ASCII or UTF-8). jQuery, by default, form-urlencodes it, which the
fossil json bits cannot read. e.g. post the result of
`JSON.stringify(requestObject)`, without any additional encoding on
top of it.
- **When POSTing via jQuery**, set these AJAX options:
- `contentType:'application/json'`
- `dataType:'text'`
- `data:JSON.stringify(requestObject)`
- **When POSTing via XMLHttpRequest** (XHR), be sure to:
- `xhr.open( … )`
- `xhr.setRequestHeader("Content-Type", "application/json")`
- `xhr.send( JSON.stringify( requestObject ) )`
The response will be (except in the case of an HTTP 500 error or
similar) a JSON or JSONP string, ready to be parsed by your favourite
`JSON.parse()` implementation or `eval()`'d directly.
<a id="curl-wget"></a>
## Using `curl` and `wget`
Both [curl](https://curl.haxx.se/) and
[wget](https://www.gnu.org/software/wget/) can be used to post data to
this API from the command line or scripts, but both require an extra
parameter to set the request encoding.
Example:
```console
$ cat x.json
{
"payload": {
"sql": "SELECT * FROM reportfmt limit 1",
"format": "o"
}
}
# Fossil has been started locally with:
# fossil server --localauth
# which allows the following requests to work without extra
# authenticaion:
$ wget -q -O- \
--post-file=x.json \
--header="Content-Type: application/json" \
'http://localhost:8080/json/query'
$ curl \
--data-binary @x.json \
--header 'Content-Type: application/json' \
'http://localhost:8080/json/query'
```
The relevant parts for encoding are the `--header` flag for `wget` and
`curl`, noting that they have different syntaxes for each
(`--header=X` vs `--header X`).
<a id="javascript"></a>
# Example JavaScript (Browser and Shell)
In the fossil source tree, [in the ajax directory](/dir/ajax), is test/demo code
implemented in HTML+JavaScript. While it is still quite experimental, it
demonstrates one approach to creating client-side wrapper APIs for
remote Fossil/JSON repositories.
There is some additional JS test code, which uses the Rhino JS engine
(i.e. from the console, not the browser), under
[`ajax/i-test`](/dir/ajax/-itest). That adds a Rhino-based connection
back-end to the AJAJ API and uses it for running integration-style
tests against an arbitrary JSON-capable repository.

# Managing Server Load
A Fossil server is very efficient and normally presents a very light
load on the server. The Fossil [self-hosting server][sh] is a 1/24th
slice VM at [Linode.com][lin] hosting 65 other repositories in addition
to Fossil, including some very high-traffic sites such as
<http://www.sqlite.org> and <http://system.data.sqlite.org>. This small
VM has a typical load of 0.05 to 0.1. A single HTTP request to Fossil
normally takes less than 10 milliseconds of CPU time to complete, so
requests can be arriving at a continuous rate of 20 or more per second,
and the CPU can still be mostly idle.
However, there are some Fossil web pages that can consume large amounts
of CPU time, especially on repositories with a large number of files or
with long revision histories. High CPU usage pages include
[`/zip`](/help/zip), [`/tarball`](/help/tarball),
[`/annotate`](/help/annotate), and others. On very large repositories,
these commands can take 15 seconds or more of CPU time. If these kinds
of requests arrive too quickly, the load average on the server can grow
dramatically, making the server unresponsive.
Fossil provides two capabilities to help avoid server overload problems
due to excessive requests to expensive pages:
1. An optional cache is available that remembers the 10 most recently
requested `/zip` or `/tarball` pages and returns the precomputed
answer if the same page is requested again.
2. Page requests can be configured to fail with a
“[503 Server Overload][503]†HTTP error if any request is
received while the host load average is too high.
Both of these load-control mechanisms are turned off by default, but
they are recommended for high-traffic sites. Users with [admin
permissions](caps/index.md) are exempt from these restrictions,
provided they are logged in before the load gets too high (login is
disabled under high load).
The webpage cache is activated using the [`fossil cache init`](/help/cache)
command-line on the server. Add a `-R` option to
specify the specific repository for which to enable caching. If running
this command as root, be sure to “`chown`†the cache database to give
the Fossil server write permission for the user ID of the web server;
this is a separate file in the same directory and with the same name as
the repository but with the “`.fossil`†suffix changed to “`.cache`â€.
To activate the server load control feature visit the Admin → Access
setup page in the administrative web interface; in the “**Server Load
Average Limit**†box enter the load average threshold above which “503
Server Overload†replies will be issued for expensive requests. On the
self-hosting Fossil server, that value is set to 1.5, but you could
easily set it higher on a multi-core server.
The maximum load average can also be set on the command line using
commands like this:
fossil setting max-loadavg 1.5
fossil all setting max-loadavg 1.5
The second form is especially useful for changing the maximum load
average simultaneously on a large number of repositories.
Note that this load-average limiting feature is only available on
operating systems that support the [`getloadavg()`][gla] API. Most
modern Unix systems have this interface, but Windows does not, so the
feature will not work on Windows.
Because Linux implements `getloadavg()` by accessing the `/proc/loadavg`
virtual file, you will need to make sure `/proc` is available to the
Fossil server. The most common reason for it to not be available is that
you are running a Fossil instance [inside a `chroot(2)`
jail](./chroot.md) and you have not mounted the `/proc` virtual file
system inside that jail. On the [self-hosting Fossil repositories][sh],
this was accomplished by adding a line to the `/etc/fstab` file:
chroot_jail_proc /home/www/proc proc ro 0 0
The `/home/www/proc` pathname should be adjusted so that the `/proc`
component is at the root of the chroot jail, of course.
To see if the load-average limiter is functional, visit the
[`/test_env`][hte] page of the server to view the current load average.
If the value for the load average is greater than zero, that means that
it is possible to activate the load-average limiter on that repository.
If the load average shows exactly "0.0", then that means that Fossil is
unable to find the load average. This can either be because it is in a
`chroot(2)` jail without `/proc` access, or because it is running on a
system that does not support `getloadavg()` and so the load-average
limiter will not function.

<title>The Fossil Build Process</title>
<h1>1.0 Introduction</h1>
The build process for Fossil is tricky in that the source code
needs to be processed by three different preprocessor programs
before it is compiled. Most users will download a
[https://fossil-scm.org/home/uv/download.html | precompiled binary]
so this is of no consequence to them, and even those who
want to compile the code themselves can use one of the
[./build.wiki | existing makefiles].
So most people do not need to be concerned with the
build complexities of Fossil. But hard-core developers who desire
a deep understanding of how Fossil is put together can benefit
from reviewing this article.
<h1 id="srctour">2.0 Source Code Tour</h1>
The source code for Fossil is found in the
[/dir?ci=trunk&name=src | src/] subdirectory of the
source tree. The src/ subdirectory contains all code, including
the code for the separate preprocessor programs.
Each preprocessor program is a separate C program implemented in
a single file of C source code. The three preprocessor programs
are:
1. [/file/tools/mkindex.c | mkindex.c]
2. [/file/tools/translate.c | translate.c]
3. [/file/tools/makeheaders.c | makeheaders.c]
Fossil uses [http://www.sqlite.org/ | SQLite] for on-disk
storage. The SQLite implementation is contained in three source
code files that do not participate in the preprocessing steps.
These three files that implement SQLite are:
4. sqlite3.c
5. sqlite3.h
6. shell.c
All three SQLite source files are byte-for-byte copies of files by
the same name in the
standard [http://www.sqlite.org/amalgamation.html | amalgamation].
The sqlite3.c file implements the database engine. The shell.c file
implements the command-line shell, which is accessed in fossil using
the [/help?cmd=sqlite3 | fossil sql] command.
The shell.c command-line shell uses the [https://github.com/antirez/linenoise |
linenoise] library to implement line editing. linenoise comprises two
source files which were copied from the upstream repository with only
very minor portability edits:
7. linenoise.c
8. linenoise.h
The TH1 script engine is implemented using files:
9. th.c
10. th.h
The preprocessing steps are omitted for all of these imported
files.
The VERSION.h header file is generated from other information sources
using a small program called:
11. [/file/tools/mkversion.c | mkversion.c]
The builtin_data.h header file contains the definitions of C-language
byte-array constants that contain various resources such as scripts and
images. The builtin_data.h header file is generated from the original
resource files using a small program called:
12 [/file/tools/mkbuiltin.c | mkbuiltin.c]
Examples of built-in resources include the [/file/src/diff.tcl | diff.tcl]
script used to implement the --tk option to [/help?cmd=diff| fossil diff],
the [/file/src/markdown.md | markdown documentation], and the various
CSS scripts, headers, and footers used to implement built-in skins. New
resources files are added to the "extra_files" variable in
[/file/tools/makemake.tcl | makemake.tcl].
The src/ subdirectory also contains documentation about the
makeheaders preprocessor program:
13. [../tools/makeheaders.html | makeheaders.html]
Click on the link to read this documentation. In addition there is
a [http://www.tcl-lang.org/ | Tcl] script used to build the various makefiles:
14. makemake.tcl
Running this Tcl script will automatically regenerate all makefiles.
In order to add a new source file to the Fossil implementation, simply
edit makemake.tcl to add the new filename, then rerun the script, and
all of the makefiles for all targets will be rebuilt.
There is an optional code verification step implemented using
15. [/file/tools/codecheck1.c | codecheck1.c]
This file implements a small utility program ("codecheck1")
that scans other Fossil source files looking for errors in printf-style
format strings.
The codecheck1 utility detects missing or surplus arguments on
printf-like functions and dangerous uses of "%s" that might
permit SQL injection or cross-site scripting attacks. This code
check step is run automatically on each build of Fossil, and can
also be run separately by typing "make codecheck". Note that the
built-in printf format checking of GCC does not function for Fossil
since Fossil implements its own printf (in the
[/file/src/printf.c | printf.c] source file) that includes special
features and formatting letters that are useful to Fossil. The
codecheck1 utility can be seen as an enhanced application-specific
replacement for the GCC printf format checker.
Finally, there is one of the makefiles generated by makemake.tcl:
16. main.mk
The main.mk makefile is invoked from the Makefile in the top-level
directory. The main.mk is generated by makemake.tcl and should not
be hand edited. Other makefiles generated by makemake.tcl are in
other subdirectories (currently all in the win/ subdirectory).
All the other files in the src/ subdirectory (79 files at the time of
this writing) are C source code files that are subject to the
preprocessing steps described below. In the sequel, we will call these
other files "src.c" in order to have a convenient name. The reader
should understand that whenever "src.c" or "src.h" is used in the text
that follows, we really mean all (79) other source files other than
the exceptions described above.
<h1>3.0 Automatically generated files</h1>
The "VERSION.h" header file contains some C preprocessor macros that
identify the version of Fossil that is to be built. The VERSION.h file is
generated automatically from information extracted from the "manifest",
"manifest.uuid", and "VERSION" source files in the root directory of the
source tree.
(The "manifest" and "manifest.uuid" files are automatically generated and
updated by Fossil itself. See the [/help/setting | fossil set manifest]
command for additional information.)
The VERSION.h header file is generated by
a C program: tools/mkversion.c.
To run the VERSION.h generator, first compile the tools/mkversion.c
source file into a command-line program (named "mkversion.exe")
then run:
<pre>
mkversion.exe manifest.uuid manifest VERSION >VERSION.h
</pre>
The pathnames in the above command might need to be adjusted to get the
directories right. The point is that the manifest.uuid, manifest, and
VERSION files
in the root of the source tree are the three arguments and
the generated VERSION.h file appears on standard output.
The builtin_data.h header file is generated by a C program: tools/mkbuiltin.c.
The builtin_data.h file contains C-language byte-array definitions for
the content of resource files used by Fossil. To generate the
builtin_data.h file, first compile the mkbuiltin.c program, then run:
<pre>
mkbuiltin.exe diff.tcl <i>OtherFiles...</i> >builtin_data.h
</pre>
At the time of this writing, the "diff.tcl" script (a Tcl/Tk script used
to generate implement --tk option on the diff command) is the only resource
file processed using mkbuiltin.exe. However, new resources will likely be
added using this facility in future versions of Fossil.
<h1 id="preprocessing">4.0 Preprocessing</h1>
There are three preprocessors for the Fossil sources. The mkindex
and translate preprocessors can be run in any order. The makeheaders
preprocessor must be run after translate.
<h2>4.1 The mkindex preprocessor</h2>
The mkindex program scans the "src.c" source files looking for special
comments that identify routines that implement various Fossil commands,
web interface methods, and help text comments. The mkindex program
generates some C code that Fossil uses in order to dispatch commands and
HTTP requests and to show on-line help. Compile the mkindex program
from the mkindex.c source file. Then run:
<pre>
./mkindex src.c >page_index.h
</pre>
Note that "src.c" in the above is a stand-in for the (79) regular source
files of Fossil - all source files except for the exceptions described in
section 2.0 above.
The output of the mkindex program is a header file that is #include-ed by
the main.c source file during the final compilation step.
<h2>4.2 The translate preprocessor</h2>
The translate preprocessor looks for lines of source code that begin
with "@" and converts those lines into string constants or (depending on
context) into special "printf" operations for generating the output of
an HTTP request. The translate preprocessor is a simple C program whose
sources are in the translate.c source file. The translate preprocess
is run on each of the other ordinary source files separately, like this:
<pre>
./translate src.c >src_.c
</pre>
In this case, the "src.c" file represents any single source file from the
set of ordinary source files as described in section 2.0 above. Note that
each source file is translated separately. By convention, the names of
the translated source files are the names of the input sources with a
single "_" character at the end. But a new makefile can use any naming
convention it wants - the "_" is not critical to the build process.
After being translated, the output files (the "src_.c" files) should be
used for all subsequent preprocessing and compilation steps.
<h2>4.3 The makeheaders preprocessor</h2>
For each C source module "src.c", there is an automatically generated
header module "src.h" that contains all of the datatype and procedure
declarations needed by the source module. These header files are generated
automatically by the makeheaders program. The sources to makeheaders
are contained in a single file "makeheaders.c". Additional documentation
on makeheaders can be found in [../tools/makeheaders.html | tools/makeheaders.html].
The makeheaders program is run once. It scans all inputs source files and
generates header files for each one. Note that the sqlite3.c and shell.c
source files are not scanned by makeheaders. Makeheaders only runs over
"ordinary" source files, not the exceptional source files. However,
makeheaders also uses some extra header files as input. The general format
is like this:
<pre>
makeheaders src_.c:src.h sqlite3.h th.h VERSION.h
</pre>
In the example above the "src_.c" and "src.h" names represent all of the
(79) ordinary C source files, each as a separate argument.
<h1>5.0 Compilation</h1>
After all generated files have been created and all ordinary source files
have been preprocessed, the generated and preprocessed files can be
combined into a single executable using a C compiler. This can be done
all at once, or each preprocessed source file can be compiled into a
separate object code file and the resulting object code files linked
together in a final step.
Some files require special C-preprocessor macro definitions.
When compiling sqlite.c, the following macros are recommended:
* -DSQLITE_OMIT_LOAD_EXTENSION=1
* -DSQLITE_ENABLE_DBSTAT_VTAB=1
* -DSQLITE_ENABLE_FTS4=1
* -DSQLITE_ENABLE_LOCKING_STYLE=0
* -DSQLITE_LIKE_DOESNT_MATCH_BLOBS=1
* -DSQLITE_THREADSAFE=0
* -DSQLITE_DEFAULT_FILE_FORMAT=4
* -DSQLITE_ENABLE_EXPLAIN_COMMENTS=1
The first three symbol definitions above are required; the others are merely
recommended. Extension loading is omitted as a security measure. The dbstat
virtual table is needed for the [/help?cmd=/repo-tabsize|/repo-tabsize] page.
FTS4 is needed for the search feature. Fossil is single-threaded so mutexing
is disabled in SQLite as a performance enhancement. The
SQLITE_ENABLE_EXPLAIN_COMMENTS option makes the output of "EXPLAIN" queries
in the "[/help?cmd=sqlite3|fossil sql]" command much more readable.
When compiling the shell.c source file, these macros are required:
* -Dmain=sqlite3_main
* -DSQLITE_OMIT_LOAD_EXTENSION=1
The "main()" routine in the shell must be changed into sqlite3_main()
to prevent it from colliding with the real main() in Fossil, and to give
Fossil an entry point to jump to when the
[/help/sqlite3 | fossil sql] command is invoked.
All the other source code files can be compiled without any special
options.
<h1>6.0 Linkage</h1>
Fossil needs to be linked against [http://www.zlib.net | zlib]. If
the HTTPS option is enabled, then it will also need to link against
the appropriate SSL implementation. And, of course, Fossil needs to
link against the standard C library. No other libraries or external
dependences are used.
<h1>7.0 Debugging</h1>
Debug mode is controlled via a FOSSIL_DEBUG preprocessor macro. This can be
set explicitly with the make command for the target platform.
However, in practice it is instead recommended to add a respective configure
option for the target platform and then perform a clean build. This way the
Debug flags are consistently applied across the whole build process. For
example, use these Debug flags in addition to other flags passed to the
configure scripts:
On Linux, *NIX and similar platforms:
<pre>
./configure --fossil-debug
</pre>
On Windows:
<pre>
win\buildmsvc.bat FOSSIL_DEBUG=1
</pre>
The resulting fossil binary can then be loaded into a platform-specific
debugger. Source files displayed in the debugger correspond to the ones
generated from the translation stage of the build process, as that is what
was actually compiled into the respective object files that make up the
fossil binary.

Note that the $ROOT translation only occurs within the `<a href="...">` element, not within the text of the hyperlink. So you should see the $ROOT text on this page, but if you mouse-over the hyperlink the $ROOT value should have been expanded to the actual document root. * Timeline: []($ROOT/timeline) * Site-map: []($ROOT/sitemap) The $ROOT prefix on markdown links is superfluous. The same link works without the $ROOT prefix. (Though: the $ROOT prefix is required for HTML documents.) * Timeline: [](/timeline) * Help: [](/help?cmd=help) * Site-map: [](/sitemap) ## The Magic $CURRENT Document Version Translation In URI text of the form `.../doc/$CURRENT/...` the $CURRENT value is converted to the version number of the document currently being displayed. This conversion happens after translation into HTML and only occurs on href='...' attributes so it does not occur for plain text. * Document index: [](/doc/$CURRENT/www/index.wiki) Both the $ROOT and the $CURRENT conversions can occur on the same link. * Document index: []($ROOT/doc/$CURRENT/www/index.wiki) The translations must be contained within HTML markup in order to work. They do not work for ordinary text that appears to be an href= attribute. * `x href='$ROOT/timeline'` * `x action="$ROOT/whatever"` * `x href="https://some-other-site.com/doc/$CURRENT/tail"` |

([Setup instructions](./mirrortogithub.md) and an [example](https://github.com/drhsqlite/fossil-mirror).) But the export to Git is not perfect. Some information is lost during export due to limitations in Git. This page describes what content of Fossil is not included in an export to Git. ## (1) Wiki, Tickets, Technotes, Forum Git only supports version control. The additional features of Fossil such as Wiki, Tickets, Technotes, and the Forum are not supported in Git, so those features are not included in an export. Third-party Git based tooling may add some of these features (e.g. GitHub, GitLab) but because their data are not stored in the Git repository, there is no single destination for Fossil to convert its equivalent data *to*. For instance, Fossil tickets do not become GitHub issues, because that is a proprietary feature of GitHub separate from Git proper, stored outside the repository on the GitHub servers. You can also see the problem in its inverse case: you do not get a copy of your GitHub issues when cloning the Git repository. You *do* get the Fossil tickets, wiki, forum posts, etc. when cloning a remote Fossil repo. ## (2) Cherrypick Merges The Git client supports cherrypick merges but does not record the cherrypick parent(s). Fossil tracks cherrypick merges in its repository and displays cherrypicks in its timeline. (As an example, the dashed lines [here](/timeline?c=0a9f12ce6655b7a5) are cherrypicks.) Because Git does not have a way to represent this same information in its repository, the history of Fossil cherrypicks cannot be exported to Git, only their direct effects on the managed file data. ## (3) Named Branches Git has only limited support for named branches. Git identifies the head check-in of each branch. Depending on the check-in graph topology, this is sufficient to infer the branch for many historical check-ins as well. However, complex histories with lots of cross-merging can lead to ambiguities. Fossil keeps track of historical branch names unambiguously, but the extra details about branch names that Fossil keeps at hand cannot be exported to Git. ## (4) Non-unique Tags Git requires tags to be unique: each tag must refer to exactly one check-in. Fossil does not have this restriction, and so it is common in Fossil to tag multiple check-ins with the same name. For example, it is common in Fossil to tag each check-in creating a release both with a unique version tag *and* a common tag like "release" so that all historical releases can be found at once. ([Example](/timeline?t=release).) Git does not allow this. The "release" tag must refer to just one check-in. The work-around is that the non-unique tag in the Git export is made to refer to only the most recent check-in with that tag. This is why the ["release" tag view][ghrtv] in the GitHub mirror of this repository shows only the latest release version; contrast the prior example. Both URLs are asking the repository the same question, but because of Git's relatively impoverished data model, it cannot give the same answer that Fossil does. [ghrtv]: https://github.com/drhsqlite/fossil-mirror/tree/release ## (5) Amendments To Check-ins Check-ins are immutable in both Fossil and Git. However, Fossil has a mechanism by which tags can be added to its repository to provide after-the-fact corrections to prior check-ins. For example, tags can be added to check-ins that correct typos in the check-in comment. The original check-in is immutable and so the original comment is preserved in addition to the correction. But software that displays the check-ins knows to look for the comment-change tag and if present displays the corrected comment rather than the original. ([Example](/info/8ed91bbe44d0d383) changing the typo "os" into "so".) Git has no mechanism for providing corrections or clarifications to historical check-ins. When exporting from Fossil to Git, the latest corrections to a Fossil check-in are used to generate the corresponding Git check-in. But once the Git check-in has been created, any subsequent corrections are omitted as there is no way to transfer them to Git. |

# How To Mirror A Fossil Repository On GitHub
Beginning with Fossil version 2.9, you can mirror a Fossil-based
project on GitHub (with [limitations](./mirrorlimitations.md))
by following these steps:
1. Create an account on GitHub if you do not have one already. Log
into that account.
2. Create a new project. GitHub will ask you if you want to prepopulate
your project with various things like a README file. Answer "no" to
everything. You want a completely blank project. GitHub will then
supply you with a URL for your project that will look something
like this:
https://github.com/username/project.git
3. Back on your workstation, move to a checkout for your Fossil
project and type:
<blockquote>
<pre>
$ fossil git export /path/to/git/repo --autopush \
https://<font color="orange">username</font>:<font color="red">password</font>@github.com/username/project.git
</pre>
</blockquote>
In place of the <code>/path/to...</code> argument above, put in
some directory name that is <i>outside</i> of your Fossil checkout. If
you keep multiple Fossil checkouts in a directory of their own,
consider using <code>../git-mirror</code> to place the Git export
mirror alongside them, for example. Fossil will create this
directory if necessary. This directory will become a Git
repository that holds a translation of your Fossil repository.
The <code>--autopush</code> option tells Fossil that you want to
push the Git translation up to GitHub every time it is updated.
The URL parameter is the same as the one GitHub gave you, but with
your GitHub <font color="orange">username</font> and <font
color="red">password</font> added.
If your GitHub account uses two-factor authentication (2FA), you
will have to <a href="https://github.com/settings/tokens">generate
a personal access token</a> and use that in place of your actual
password in the URL. This token should have “repo†scope enabled,
only.
You can also run the command above outside of any open checkout of
your project by supplying the “<code>-R repository</code>â€
option.
4. Get some coffee. Depending on the size of your project, the
initial "<code>fossil git export</code>" command in the previous
step might run for several minutes.
5. And you are done! Assuming everything worked, your project is now
mirrored on GitHub.
6. Whenever you update your project, simply run this command to update
the mirror:
$ fossil git export
Unlike with the first time you ran that command, you don’t need
the remaining arguments, because Fossil remembers those things.
Subsequent mirror updates should usually happen in a fraction of
a second.
7. To see the status of your mirror, run:
$ fossil git status
## Notes:
* Unless you specify --force, the mirroring only happens if the Fossil
repo has changed, with Fossil reporting "no changes", because Fossil
does not care about the success or failure of the mirror run. If a mirror
run failed (for example, due to an incorrect password, or a transient
error at github.com), Fossil will not retry until there has been a repo
change or --force is supplied.
* The mirroring is one-way. If you check in changes on GitHub, those
changes will not be reabsorbed by Fossil. There are technical problems
that make a two-way mirror all but impossible. (This is not to be
confused with the ability to import a Fossil mirror from Github back
into a Fossil repository. That works, but it is not a mirror.)
This also means that you cannot accept pull requests on GitHub.
* The "`fossil git export`" command creates subprocesses that run "`git`"
commands, so you must have Git installed on your machine for any
of this to work.
* The Git repository will have an extra unmanaged top-level directory named
"`.mirror_state`" that contains one or more files. Those files are
used to store the intermediate state of the translation so that
subsequent invocations of "`fossil git export`" will know where you
left off the last time and what new content needs to be moved over into
Git. Be careful not to mess with the `.mirror_state` directory or
any of its contents. Do not put those files under Git management. Do
not edit or delete them.
* The name of the "trunk" branch is automatically translated into "master"
in the Git mirror unless you give the `--mainbranch` option.
* Only check-ins and simple tags are translated to Git. Git does not
support wiki or tickets or unversioned content or any of the other
features of Fossil that make it so convenient to use, so those other
elements cannot be mirrored in Git.
* In Git, all tags must be unique. If your Fossil repository has the
same tag on two or more check-ins, the tag will only be preserved on
the chronologically newest check-in.
* There is a
[long list of restrictions](https://git-scm.com/docs/git-check-ref-format)
on tag and branch names in Git. If any of your Fossil tag or branch names
violate these rules, then the names are translated prior to being exported
to Git. The translation usually involves converting the offending characters
into underscores.
* If your Fossil user contact info is not set and this repository was not
initially [imported from Git](./inout.wiki), `fossil git export` will
construct a generic `user@noemail.net` for the Git *committer* and *author*
email fields of each commit. However, Fossil will first attempt to parse an
email address from your user contact info, which can be set through a
Fossil [UI][ui] browser window or with the [`user contact`][usercmd]
subcommand on the command line. Alternatively, if this repository was
previously imported from Git using the [`--attribute`][attr] option, the
[`fx_git`][fxgit] table will be queried for correspondent email addresses.
Only if neither of these methods produce a user specified email will the
abovementioned generic address be used.
[attr]: /help?cmd=import
[fxgit]: ./inout.wiki#fx_git
[ui]: /help?cmd=ui
[usercmd]: /help?cmd=user
## <a id='ex1'></a>Example GitHub Mirrors
As of this writing (2019-03-16) Fossil’s own repository is mirrored
on GitHub at:
> <https://github.com/drhsqlite/fossil-mirror>
In addition, an official Git mirror of SQLite is available:
> <https://github.com/sqlite/sqlite>
The Fossil source repositories for these mirrors are at
<https://www2.fossil-scm.org/fossil> and <https://www2.sqlite.org/src>,
respectively. Both repositories are hosted on the same VM at
[Linode](https://www.linode.com). On that machine, there is a
[cron job](https://linux.die.net/man/8/cron)
that runs at 17 minutes after the hour, every hour that does:
/usr/bin/fossil sync -u -R /home/www/fossil/fossil.fossil
/usr/bin/fossil sync -R /home/www/fossil/sqlite.fossil
/usr/bin/fossil git export -R /home/www/fossil/fossil.fossil
/usr/bin/fossil git export -R /home/www/fossil/sqlite.fossil
The initial two "sync" commands pull in changes from the primary
Fossil repositories for Fossil and SQLite. The last two lines
export the changes to Git and push the results up to GitHub.

<title>How To Create A New Fossil Repository</title>
The [/doc/tip/www/quickstart.wiki|quickstart guide] explains how
to get up and running with fossil. But once you're running, what can
you do with it? This document will walk you through the process of
creating a fossil repository, populating it with files, and then
sharing it over the web.
The first thing we need to do is create a fossil repository file:
<verbatim>
$ fossil new demo.fossil
project-id: 9d8ccff5671796ee04e60af6932aa7788f0a990a
server-id: 145fe7d71e3b513ac37ac283979d73e12ca04bfe
admin-user: stephan (initial password is ******)
</verbatim>
The numbers it spits out are unimportant (they are version
numbers).
Now we have an empty repository file named <tt>demo.fossil</tt>.
There is nothing magical about the extension <tt>.fossil</tt> - it's
just a convention. You may name your files anything you like.
The first thing we normally want to do is to run fossil as a local server so
that you can configure the access rights to the repo:
<verbatim>
$ fossil ui demo.fossil
</verbatim>
The <tt>ui</tt> command starts up a server (with an optional <tt>-port
NUMBER</tt> argument) and launches a web browser pointing at the
fossil server. From there it takes just a few moments to configure the
repo. Most importantly, go to the Admin menu, then the Users link, and
set your account name and password, and grant your account all access
privileges. (I also like to grant Clone access to the anonymous user,
but that's personal preference.)
Once you are done, kill the fossil server (with Ctrl-C or equivalent)
and close the browser window.
<div class="sidebar">
It is not strictly required to configure a repository
this way, but if you are going to share a repo over the net then it
is highly recommended. If you are only going to work with the repo
locally, you can skip the configuration step and do it later if
you decide you want to share your repo.
</div>
The next thing we need to do is <em>open</em> the repository. To do so
we create a working directory and then <tt>cd</tt> to it:
<verbatim>
$ mkdir demo
$ cd demo
$ fossil open ../demo.fossil
</verbatim>
That creates a file called <tt>_FOSSIL_</tt> in the current
directory, and this file contains all kinds of fossil-related
information about your local repository. Under Linux, the BSDs or
macOS, this will instead be called <tt>.fslckout</tt>. You can ignore it
for all purposes, but be sure not to accidentally remove it
or otherwise damage it - it belongs to fossil, not you.
The next thing we need to do is add files to our repository. As it
happens, we have a few C source files lying around, which we'll
simply copy into our working directory.
<verbatim>
$ cp ../csnip/*.{c,h} .
$ ls
clob.c clob.h clobz.c mkdep.c test-clob.c
tokenize_path.c tokenize_path.h vappendf.c vappendf.h
</verbatim>
Fossil doesn't know about those files yet. Telling fossil about
a new file is a two-step process. First we <em>add</em> the file
to the repository, then we <em>commit</em> the file. This is a familiar
process for anyone who's worked with SCM systems before:
<verbatim>
$ fossil add *.{c,h}
$ fossil commit -m "egg"
New_Version: d1296b4a08b9f8b943bb6c73698e51eed23f8f91
</verbatim>
We now have a working repository! The file <tt>demo.fossil</tt>
is the central storage, and we can share it amongst an arbitrary
number of trees. As a silly example:
<verbatim>
$ cd ~/fossil
$ mkdir demo2
$ cd demo2
$ fossil open ../demo.fossil
ADD clob.c
ADD clob.h
ADD clobz.c
ADD mkdep.c
ADD test-clob.c
ADD tokenize_path.c
ADD tokenize_path.h
ADD vappendf.c
</verbatim>
You may modify the repository (e.g. add, remove, or commit files) from
both working directories, and doing so might be useful when working on
a branch or experimental code.
Making your repository available over the web is trivial to do. We
assume you have some web space where you can store your fossil file
and run a CGI script. If not, then this option is not for you. If
you do, then here's how...
Copy the fossil repository file to your web server (it doesn't matter
where, really, but it "should" be unreachable by web browser traffic).
In your <tt>cgi-bin</tt> (or equivalent) directory, create a file
which looks like this:
<verbatim>
#!/path/to/fossil
repository: /path/to/my_repo.fossil
</verbatim>
Make that script executable, and you're all ready to go:
<verbatim>
$ chmod +x ~/www/cgi-bin/myrepo.cgi
</verbatim>
Now simply point your browser to
<tt>https://my.domain/cgi-bin/myrepo.cgi</tt> and you should
be able to manage the repository from there.
To check out a copy of your remote repository, use the
<em>clone</em> command:
<verbatim>
$ fossil clone \
https://MyAccountName:MyAccountPassword@my.domain/cgi-bin/myrepo.cgi
</verbatim>
If you do not provide your password in the URL, fossil will
interactively prompt you for it.
A clone is a local copy of a remote repository, and can be opened just
like a local one (as shown above). It is treated identically to your
local repository, with one very important difference. When you commit
changes to a cloned remote repository, they will be pushed back to the
remote repository. If you have <tt>autosync</tt> on then this sync
happens automatically, otherwise you will need to use the
<em>pull</em> command to get remote changes and the <em>push</em>
command to push your local commits to the remote repository. You must
of course have authorization to commit changes (access is configured
via the Admin/Users page mentioned above).
You may always use the <em>server</em> or <em>ui</em> commands to
browse a cloned repository. You can even edit create or wiki entries,
etc., and they will be pushed to the remote side the next time you
push data to the remote.

Passwords are unique to each repository. Passwords are not part of the persistent state of a project. Passwords are not versioned and are not transmitted from one repository to another during a sync. Passwords are local configuration information that can (and usually does) vary from one repository to the next within the same project. Passwords are stored in the PW field of the USER table. In older versions of Fossil (prior to [/timeline?c=2010-01-10T20:56:30 | 2010-01-11]) the password is stored as cleartext. In newer versions of Fossil, the password can be either cleartext or an SHA1 hash (written as a 40-character lower-case hexadecimal number). If the USER.PW field contains a 40-character string, that string is assumed to be a SHA1 hash. If the size of USER.PW is anything other than 40 characters, then it is understood as a plain-text password. The SHA1 hash in the USER.PW field is a hash of a string composed of the project-code, the user login, and the user cleartext password. Suppose user "alice" with password "asdfg" had an account on the Fossil self-hosting repository. Then the value of USER.PW for alice would be the SHA1 hash of <pre> CE59BB9F186226D80E49D1FA2DB29F935CCA0333/alice/asdfg </pre> Note that by including the project-code and the login as part of the hash, a different USER.PW value results even if two or more users on the repository select the same "asdfg" password or if user alice reuses the same password on multiple projects. Whenever a password is changed using the web interface or using the "user" command-line method, the new password is stored using the SHA1 encoding. Thus, cleartext passwords will gradually migrate to become SHA1 passwords. All remaining cleartext passwords can be converted to SHA1 passwords using the following command: <pre> fossil test-hash-passwords <i>REPOSITORY-NAME</i> </pre> Remember that converting from cleartext to SHA1 passwords is an irreversible operation. The only way to insert a new cleartext password into the USER table is to do so manually using SQL commands. For example: <pre> UPDATE user SET pw='asdfg' WHERE login='alice'; </pre> Note that an password that is an empty string or NULL will disable all login for that user. Thus, to lock a user out of the system, one has only to set their password to an empty string, using either the web interface or direct SQL manipulation of the USER table. Note also that the password field is essentially ignored for the special users named "anonymous", "developer", "reader", and "nobody". It is not possible to authenticate as users "developer", "reader", or "nobody" and the authentication protocol for "anonymous" uses one-time captchas not persistent passwords. <h2>Web Interface Authentication</h2> When a user logs into Fossil using the web interface, the login name and password are sent in the clear to the server. For most modern fossil server setups with [/help?cmd=redirect-to-https|redirect-to-https] enabled, this will be protected by the SSL connection over HTTPS so it cannot be easily viewed. The server then hashes the password and compares it against the value stored in USER.PW. If they match, the server sets a cookie on the client to record the login. This cookie contains a large amount of high-quality randomness and is thus intractable to guess. The value of the cookie and the IP address of the client is stored in the USER.COOKIE and USER.IPADDR fields of the USER table on the server. The USER.CEXPIRE field holds an expiration date for the cookie, encoded as a Julian day number. On all subsequent HTTP requests, the cookie value is matched against the USER table to enable access to the repository. Note that in order to log into a Fossil server, it is necessary to write information into the repository database. Hence, login is not possible on a Fossil repository with a read-only database file. The user password is sent over the wire as cleartext on the initial login attempt. The plan moving forward is to compute the SHA1 hash of the password on the client using JavaScript and then send only the hash over the wire, but that plan has not yet been set in code. <h2>Sync Protocol Authentication</h2> A different authentication mechanism is used when one repository wants to sync (or push or pull or clone) another repository. When two repositories are syncing, the one that initiates the transaction is the client and the repository that responds is the server. The client works by sending HTTP requests to the server with a method of "xfer" and a content-type of "application/x-fossil". The content is Zlib-compressed text consisting of "cards" of instructions. The first card of this content is a "login" card responsible for authentication. The login card contains the login name of the user and a "signature" where the signature is the SHA1 hash of a nonce and the value of USER.PW. The nonce is the |
| ︙ | ︙ | |||
130 131 132 133 134 135 136 | This means that when USER.PW holds a cleartext password, the login card will work for both older and newer clients. If the USER.PW on the server only holds the SHA1 hash of the password, then only newer clients will be able to authenticate to the server. The client normally gets the login and password from the "remote URL". | | | | | | | | | | | 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 | This means that when USER.PW holds a cleartext password, the login card will work for both older and newer clients.

For newer clients, the shared secret is derived from the password by transforming the password using the SHA1 hash encoding described above. However, if the first character of the password is "*" (ASCII 0x2a) then the "*" is skipped and the rest of the password is used directly as the share secret without the SHA1 encoding. <pre> http://<span style="color:blue">login:*password</span>@servername.org/path </pre> This *-before-the-password trick can be used by newer clients to sync against a legacy server that does not understand the new SHA1 password encoding. |

# The "fossil patch" command
The "[fossil patch](/help?cmd=patch)" command is designed to transfer
uncommitted changes from one check-out to another, including transfering
those changes to other machines.
For example, if you are working on a Windows desktop and you want to
test your changes on a Linux server before you commit, you can use the
"fossil patch push" command to make a copy of all your changes on the
remote Linux server:
fossil patch push linuxserver:/path/to/checkout
In the previous line "linuxserver" is the name of the remote machine and
"/path/to/checkout" is an existing checkout directory for the same project
on the remote machine.
The "fossil patch push" command works by first creating a patch file,
then transfering that patch file to the remote machine using "ssh", then
applying the patch. If you do not have ssh available, you can break these
steps apart as follows:
1. On the local machine: `fossil patch create mypatch.patch`
2. Move "mypatch.patch" to the remote machine.
3. On the remote machine: `fossil patch apply mypatch.patch`
Step 2 can be accomplished by a variety of means including
posting the mypatch.patch file on [chat](./chat.md) or sending
it as an email attachment.
## Setup
The "fossil patch push" and "fossil patch pull" commands will only work if you have
"ssh" available on the local machine and if "fossil" is on the default
PATH on the remote machine.
To check if Fossil is installed correctly on the remote, try a command
like this:
ssh -T remote "fossil version"
If the command above shows a recent version of Fossil, then you should be
set to go. If you get "fossil not found", or if the version shown is too
old, put a newer fossil executable on the default PATH. The default PATH
can be shown using:
ssh -T remote 'echo $PATH'
### Custom PATH Caveat
On Unix-like systems, the init script for the user's login shell
(e.g. `~/.profile` or `~/.bash_profile`) may be configured to *not do
anything* when running under a non-interactive shell. Thus a fossil
binary installed to a custom directory might not be found. To allow
the patch command to use a fossil binary installed in a directory
which is normally added to the PATH via the interactive shell's init
script, it may be useful to disable that check. For example,
Ubuntu-derived systems sometimes start their default `.bashrc` with
something like:
```
# If not running interactively, don't do anything:
[ -z "$PS1" ] && return
# Or:
case $- in
*i*) ;;
*) return;;
esac
```
Commenting out that check will allow the patch command to run, for
example, `~/bin/fossil` if `~/bin` is added to the PATH via the init
script. To disable that check *only* when the shell is *not* running
over an SSH connection, something like the following should suffice:
```
if [ -z "$SSH_CONNECTION" ]; then
# ... the is-interactive check goes here ...
fi
```
## Implementation Details
The "fossil patch create" command records all of the local, uncommitted
changes in an SQLite database file. If the argument to "fossil patch create"
is a filename, then the patch-file database is written into that file.
If the argument is "-" then the database is written on standard output.
The "fossil patch apply" command reads the patch-file database
and applies it to the local check-out. If a filename is given as an
argument, then the database is read from that file. If the argument is "-"
then the database is read from standard input.
Hence the command:
fossil patch push remote:projectA
Is equivalent to:
fossil patch create - | ssh -T remote 'cd projectA;fossil patch apply -'
Likewise, a command like this:
fossil patch pull remote:projB
could be entered like this:
ssh -T remote 'cd projB;fossil patch create -' | fossil patch apply -
The "fossil patch view" command just opens the patch-file database and prints
a summary of its contents on standard output.

# The Pikchr Diagram Language
Pikchr (pronounced "picture") is a [PIC][1]-like markup language for creating
diagrams in technical documentation. Source text for Pikchr diagrams
can be embedded directly in either [Markdown][2] or [Fossil Wiki][3].
Fossil translates the Pikchr source text into SVG which is displayed as
part of the rendered wiki.
[1]: wikipedia:/wiki/Pic_language
[2]: /md_rules
[3]: /wiki_rules
For example, this document is written in Markdown. The following
is a sample Pikchr diagram:
``` pikchr
arrow right 200% "Markdown" "Source"
box rad 10px "Markdown" "Formatter" "(markdown.c)" fit
arrow right 200% "HTML+SVG" "Output"
arrow <-> down 70% from last box.s
box same "Pikchr" "Formatter" "(pikchr.c)" fit
```
The diagram above was generated by the following lines of Markdown:
~~~~~
``` pikchr
arrow right 200% "Markdown" "Source"
box rad 10px "Markdown" "Formatter" "(markdown.c)" fit
arrow right 200% "HTML+SVG" "Output"
arrow <-> down 70% from last box.s
box same "Pikchr" "Formatter" "(pikchr.c)" fit
```
~~~~~
See the [original Markdown source text of this document][4] for an
example of Pikchr in operation.
[4]: ./pikchr.md?mimetype=text/plain
Fossil allows Pikchr diagrams to appear anywhere that Markdown or
Fossil Wiki markup or used, including:
* [Embedded documentation](./embeddeddoc.wiki)
* Stand-alone wiki pages
* [Wiki pages associated with particular branches or check-ins](./wikitheory.wiki#assocwiki)
* Check-in comments
* [Technical notes](./event.wiki)
* [Forum posts](./forum.wiki)
* [Bug reports and trouble tickets](./bugtheory.wiki)
## Pikchr Is A Separate Project
Even though the original author of Pikchr is the same as the original
creator of Fossil, the sources to the Pikchr formatter are maintained
as a [separate project named "pikchr.org"](https://pikchr.org).
Pikchr is a delivered as a single file of C code. The "pikchr.c" file
from the Pikchr project is periodically copied into the Fossil source
tree. Pikchr is maintained as a project distinct from Fossil so that it
can be used independently of Fossil.
### Pikchr User Manual And Tutorials
Complete documentation on the Pikchr language can be found on the
Pikchr project page:
* <https://pikchr.org/>
That website contains a user manual, tutorials, a language specification,
a summary of differences between Pikchr and legacy PIC,
and it hosts copies of historical PIC documentation.
## How To Include Pikchr Diagrams In Fossil Documents
To illustrate how to include Pikchr in Fossil markup, we will use the
following one-line Pikchr. Click to see the code:
~~~ pikchr toggle
arrow; box "Hello" "World!" fit; arrow
~~~
For Markdown, the Pikchr code is put inside of a
[fenced code block][fcb]. A fenced code block is the text in between
``` ... ``` or between
~~~ ... ~~~ using three or
more ` or ~ characters. The fenced code block normally
displays its content verbatim, but if an "info string" of "pikchr"
follows the opening ``` or ~~~, then the
content is interpreted as Pikchr script and is replaced by the
equivalent SVG.
So either of these work:
[fcb]: https://spec.commonmark.org/0.29/#fenced-code-blocks
~~~~~~
~~~ pikchr
arrow; box "Hello" "World!" fit; arrow
~~~
``` pikchr
arrow; box "Hello" "World!" fit; arrow
```
~~~~~~
For Fossil Wiki, the Pikchr code goes within
`<verbatim type="pikchr"> ... </verbatim>`. Normally `<verbatim>`
content is displayed verbatim. The extra `type="pikchr"` attribute
causes the content to be interpreted as Pikchr and replaced by SVG.
~~~~~~
<verbatim type="pikchr">
arrow; box "Hello" "World!" fit; arrow
</verbatim>
~~~~~~
## Extra Arguments In "Pikchr" Code Blocks
Extra formatting arguments can be included in the fenced code block start
tag, or in the "`type=`" attribute of `<verbatim>`, to change the formatting
of the diagram.
* **indent** → The diagram is indented from the left margin.
* **center** → The diagram is centered
* **toggle** → Clicking on the diagram toggles between showing
the rendered SVG and the original Pikchr source text. You can always
do this by holding down the Ctrl or Alt keys and clicking. The
"toggle" option just means you can toggle without holding down any
extra keys.
* **float-left** → The diagram is shown at the left margin and
text fills in around the diagram.
* **float-right** → The diagram is shown at the right margin and
text fills in around the diagram.
* **source** → The display starts out showing the Pikchr source text.
The reader must click (or Alt-click or Ctrl-click) to show the diagram.

<title>Principles Of Operation</title>
This page attempts to define the foundational principals upon
which Fossil is built.
* A project consists of source files, wiki pages, and
trouble tickets, and control files (collectively "artifacts").
All historical copies of all artifacts
are saved. The project maintains an audit
trail.
* A project resides in one or more repositories. Each
repository is administered and operates independently
of the others.
* Each repository has both global and local state. The
global state is common to all repositories (or at least
has the potential to be shared in common when the
repositories are fully synchronized). The local state
for each repository is private to that repository.
The global state represents the content of the project.
The local state identifies the authorized users and
access policies for a particular repository.
* The global state of a repository is an unordered
collection of artifacts. Each artifact is named by a
cryptographic hash (SHA1 or SHA3-256) encoded in
lowercase hexadecimal.
In many contexts, the name can be
abbreviated to a unique prefix. A five- or six-character
prefix usually suffices to uniquely identify a file.
* Because artifacts are named by a cryptographic hash, all artifacts
are immutable. Any change to the content of an artifact also
changes the hash that forms the artifacts name, thus
creating a new artifact. Both the old original version of the
artifact and the new change are preserved under different names.
* It is theoretically possible for two artifacts with different
content to share the same hash. But finding two such
artifacts is so incredibly difficult and unlikely that we
consider it to be an impossibility.
* The signature of an artifact is the cryptographic hash of the
artifact itself, exactly as it would appear in a disk file. No prefix
or meta-information about the artifact is added before computing
the hash. So you can
always find the signature of a file by using the
"sha1sum" or "sha3sum" or similar command-line utilities.
* The artifacts that comprise the global state of a repository
are the complete global state of that repository. The SQLite
database that holds the repository contains additional information
about linkages between artifacts, but all of that added information
can be discarded and reconstructed by rescanning the content
artifacts.
* Two repositories for the same project can synchronize
their global states simply by sharing artifacts. The local
state of repositories is not normally synchronized or
shared.
* Every check-in has a special file at the top-level
named "manifest" which is an index of all other files in
that check-in. The manifest is automatically created and
maintained by the system.
* The <a href="fileformat.wiki">file formats</a>
used by Fossil are all very simple so that with access
to the original content files, one can easily reconstruct
the content of a check-in without the need for any
special tools or software.

<title>Private Branches</title>
By default, everything you check into a Fossil repository is shared
to all clones of that repository. In Fossil, you don't push and pull
individual branches; you push and pull everything all at once.
But sometimes users want to keep some private work that is not
shared with others. This might be a preliminary or experimental change
that needs further refinement before it is shared and which might never
be shared at all. To do this in Fossil, simply commit the change with
the --private command-line option:
<pre>
fossil commit --private
</pre>
The --private option causes Fossil to put the check-in in a new branch
named "private". That branch will not participate in subsequent clone,
sync, push, or pull operations. The branch will remain on the one local
repository where it was created. Note that you only use the --private
option for the first check-in that creates the private branch.
Additional checkins into the private branch remain private automatically.
<h2>Publishing Private Changes</h2>
After additional work, one might desire to publish the changes associated
with a private branch. The usual way to do this is to merge those
changes into a public branch. For example:
<pre>
fossil update trunk
fossil merge private
fossil commit
</pre>
The private branch remains private and is not recorded as a parent
in the merge manifest's P-card, but all of the changes associated with
the private branch are now folded into the public branch and are hence
visible to other users of the project.
A private branch created with Fossil version 1.30 or newer can also be
converted into a public branch using the <code>fossil publish</code>
command. However, there is no way to convert a private branch created with
older versions of Fossil into a public branch.
<div class="sidebar">
To avoid generating a missing artifact
reference on peer repositories without the private branch, the merge parent
is not recorded when merging the private branch into a public branch. As a
consequence, the web UI timeline does not draw a merge line from the private
merge parent to the public merge child. Moreover, repeat private-to-public
merge operations (without the [/help?cmd=merge | --force option]) with files
added on the private branch may only work once, but later abort with
"WARNING: no common ancestor for FILE", as the parent-child relationship is
not recorded. (See the [/doc/trunk/www/branching.wiki | Branching, Forking,
Merging, and Tagging] document for more information.)
</div>
The <code>--integrate</code> option of <code>fossil merge</code> (to close
the merged branch when committing) is ignored for a private branch -- or the
check-in manifest of the resulting merge child would include a
<code>+close</code> tag referring to the leaf check-in on the private branch,
and generate a missing artifact reference on repository clones without that
private branch. It's still possible to close the leaf of the private branch
(after committing the merge child) with the <code>fossil amend --close</code>
command.
<h2>Syncing Private Branches</h2>
A private branch normally stays on the one repository where it was
originally created. But sometimes you want to share private branches
with another repository. For example, you might be building a cross-platform
application and have separate repositories on your Windows laptop,
your Linux desktop, and your iMac. You can transfer private branches
between these machines by using the --private option on the "sync",
"push", "pull", and "clone" commands. For example, if you are running
"fossil server" on your Linux box and you want to clone that repository
to your Mac, including all private branches, use:
<verbatim>
fossil clone --private http://user@linux.localnetwork:8080/ mac-clone.fossil
</verbatim>
You'll have to supply a username and password in order for this to work.
Fossil will not clone (or sync) private branches anonymously.
By default, there are no users that can do private branch syncing. You
will have to give a user
the "Private" capability ("x") if you want them to be able to do this.
We deny such capability for normal users by default to add a barrier to
accidental syncing of a private branch to a public server. It is highly recommended that
you leave the "x" capability turned off on all repositories used for
collaboration (repositories to which many people push and pull) and
only enable "x" for local repositories when you need to share private
branches.
Private branch sync only works if you use the --private command-line option.
Private branches are never synced via the auto-sync mechanism. Once
again, this restriction is designed to make it hard to accidentally
push private branches beyond their intended audience.
<h2>Purging Private Branches</h2>
You can remove all private branches from a repository using this command:
<pre>
fossil scrub --private
</pre>
Note that the above is a permanent and irreversible change. You will
be asked to confirm before continuing. Once the private branches are
removed, they cannot be retrieved (unless you have synced them to another
repository.) So be careful with the command.
<h2>Additional Notes</h2>
All of the features above apply to <u>all</u> private branches in a
single repository at once. There is no mechanism in Fossil (currently)
that allows you to push, pull, clone, sync, or scrub an individual

<title>Questions And Criticisms</title>
This page is a collection of real questions and criticisms that were
raised against Fossil early in its history (circa 2008).
This page is old and has not been kept up-to-date. See the
[/finfo?name=www/qandc.wiki|change history of this page].
<b>Fossil sounds like a lot of reinvention of the wheel.
Why create your own DVCS when you could have reused mercurial?</b>
<div class="indent">
I wrote fossil because none of the
other available DVCSes met my needs. If the other DVCSes do
meet your needs, then you might not need fossil. But they
don't meet mine, and so fossil is necessary for me.
Features provided by fossil that one does not get with other
DVCSes include:
<ol>
<li> Integrated <a href="wikitheory.wiki">wiki</a>. </li>
<li> Integrated <a href="bugtheory.wiki">bug tracking</a> </li>
<li> Immutable artifacts </li>
<li> Self-contained, stand-alone executable that can be run in
a <a href="http://en.wikipedia.org/wiki/Chroot">chroot jail</a> </li>
<li> Simple, well-defined,
<a href="fileformat.wiki">enduring file format</a> </li>
<li> Integrated <a href="webui.wiki">web interface</a> </li>
</ol>
</div>
<b>Why should I use this rather than Trac?</b>
<div class="indent">
<ol>
<li> Fossil is distributed. You can view and/or edit tickets, wiki, and
code while off network, then sync your changes later. With Trac, you
can only view and edit tickets and wiki while you are connected to
the server. </li>
<li> Fossil is lightweight and fully self-contained. It is very easy
to setup on a low-resource machine. Fossil does not require an
administrator.</li>
<li> Fossil integrates code versioning into the same repository with
wiki and tickets. There is nothing extra to add or install.
Fossil is an all-in-one turnkey solution. </li>
</ol>
</div>
<b>Love the concept here. Anyone using this for real work yet?</b>
<div class="indent">
Fossil is <a href="https://fossil-scm.org/">self-hosting</a>.
In fact, this page was probably delivered
to your web-browser via a working fossil instance. The same virtual
machine that hosts https://fossil-scm.org/
(a <a href="http://www.linode.com/">Linode 720</a>)
also hosts 24 other fossil repositories for various small projects.
The documentation files for
<a href="http://www.sqlite.org/">SQLite</a> are hosted in a
fossil repository <a href="http://www.sqlite.org/docsrc/">here</a>,
for example.
Other projects are also adopting fossil. But fossil does not yet have
the massive user base of git or mercurial.
</div>
<b>Fossil looks like the bug tracker that would be in your
Linksys Router's administration screen.</b>
<div class="indent">
I take a pragmatic approach to software: form follows function.
To me, it is more important to have a reliable, fast, efficient,
enduring, and simple DVCS than one that looks pretty.
On the other hand, if you have patches that improve the appearance
of Fossil without seriously compromising its reliability, performance,
and/or maintainability, I will be happy to accept them. Fossil is
self-hosting. Send email to request a password that will let
you push to the main fossil repository.
</div>
<b>It would be useful to have a separate application that
keeps the bug-tracking database in a versioned file. That file can
then be pushed and pulled along with the rest repository.</b>
<div class="indent">
Fossil already <u>does</u> push and pull bugs along with the files
in your repository.
But fossil does <u>not</u> track bugs as files in the source tree.
That approach to bug tracking was rejected for three reasons:
<ol>
<li> Check-ins in fossil are immutable. So if
tickets were part of the check-in, then there would be no way to add
new tickets to a check-in as new bugs are discovered.
<li> Any project of reasonable size and complexity will generate thousands
and thousands of tickets, and we do not want all those ticket files
cluttering the source tree.
<li> We want tickets to be managed from the web interface and to have a
permission system that is distinct from check-in permissions.
In other words, we do not want to restrict the creation and editing
of tickets to developers with check-in privileges and an installed
copy of the fossil executable. Casual passers-by on the internet should
be permitted to create tickets.
</ol>
These points are reiterated in the opening paragraphs of
the <a href="bugtheory.wiki">Bug-Tracking In Fossil</a> document.
</div>
<b>Fossil is already the name of a plan9 versioned
append-only filesystem.</b>
<div class="indent">
I did not know that. Perhaps they selected the name for the same reason that
I did: because a repository with immutable artifacts preserves
an excellent fossil record of a long-running project.
</div>
<b>The idea of storing a repository in a binary blob like an
SQLite database terrifies me.</b>
<div class="indent">
The use of SQLite to store the database is likely more stable and secure
than any other approach, due to the fact that SQLite is transactional.
Fossil also implements several internal
<a href="selfcheck.wiki">self-checks</a> to insure that no information
is ever lost.
</div>
<b>I am dubious of the benefits of including wikis and bug trackers
directly in the VCS - either they are under-featured compared to full
software like Trac, or the VCS is massively bloated compared to
Subversion or Bazaar.</b>
<div class="indent">
I have no doubt that Trac has many features that fossil lacks. But that
is not the point. Fossil has several key features that Trac lacks and that
I need: most notably the fact that
fossil supports disconnected operation.
As for bloat: Fossil is a single self-contained executable.
You do not need any other packages
(diff, patch, merge, cvs, svn, rcs, git, python, perl, tcl, apache,
SQLite, and so forth)
in order to run fossil. Fossil runs just fine in a chroot jail all
by itself. And the self-contained fossil
executable is much less than 1MB in size. (Update 2015-01-12: Fossil has
grown in the years since the previous sentence was written but is still
much less than 2MB according to "size" when compiled using -Os on x64 Linux.)
Fossil is the very opposite of bloat.

<title>Fossil Quick Start Guide</title>
This is a guide to help you get started using the Fossil [https://en.wikipedia.org/wiki/Distributed_version_control|Distributed Version Control System] quickly
and painlessly.
<h2 id="install">Installing</h2>
Fossil is a single self-contained C program. You need to
either download a
[https://fossil-scm.org/home/uv/download.html|precompiled
binary]
or <a href="build.wiki">compile it yourself</a> from sources.
Install Fossil by putting the fossil binary
someplace on your $PATH.
You can test that Fossil is present and working like this:
<pre><b>fossil version
This is fossil version 2.13 [309af345ab] 2020-09-28 04:02:55 UTC
</b></pre>
<h2 id="workflow" name="fslclone">General Work Flow</h2>
Fossil works with repository files (a database in a single file with the project's
complete history) and with checked-out local trees (the working directory
you use to do your work).
(See [./glossary.md | the glossary] for more background.)
The workflow looks like this:
<ul>
<li>Create or clone a repository file. ([/help/init|fossil init] or
[/help/clone | fossil clone])
<li>Check out a local tree. ([/help/open | fossil open])
<li>Perform operations on the repository (including repository
configuration).
</ul>
Fossil can be entirely driven from the command line. Many features
can also be conveniently accessed from the built-in web user interface.
The following sections give a brief overview of these
operations.
<h2 id="new">Starting A New Project</h2>
To start a new project with fossil create a new empty repository
this way: ([/help/init | more info])
<pre><b>fossil init</b> <i>repository-filename</i>
</pre>
You can name the database anything you like, and you can place it anywhere in the filesystem.
The <tt>.fossil</tt> extension is traditional but only required if you are going to use the
<tt>[/help/server | fossil server DIRECTORY]</tt> feature.â€
<h2 id="clone">Cloning An Existing Repository</h2>
Most fossil operations interact with a repository that is on the
local disk drive, not on a remote system. Hence, before accessing
a remote repository it is necessary to make a local copy of that
repository. Making a local copy of a remote repository is called
"cloning".
Clone a remote repository as follows: ([/help/clone | more info])
<pre><b>fossil clone</b> <i>URL repository-filename</i>
</pre>
The <i>URL</i> specifies the fossil repository
you want to clone. The <i>repository-filename</i> is the new local
filename into which the cloned repository will be written. For
example, to clone the source code of Fossil itself:
<pre><b>fossil clone https://fossil-scm.org/ myclone.fossil</b></pre>
If your logged-in username is 'exampleuser', you should see output something like this:
<pre><b>Round-trips: 8 Artifacts sent: 0 received: 39421
Clone done, sent: 2424 received: 42965725 ip: 10.10.10.0
Rebuilding repository meta-data...

Extra delta compression...
Vacuuming the database...
project-id: 94259BB9F186226D80E49D1FA2DB29F935CCA0333
server-id: 016595e9043054038a9ea9bc526d7f33f7ac0e42
admin-user: exampleuser (password is "yoWgDR42iv")>
</b></pre>
If the remote repository requires a login, include a
userid in the URL like this:
<pre><b>fossil clone https://</b><i>remoteuserid</i><b>@www.example.org/ myclone.fossil</b></pre>
You will be prompted separately for the password.
Use [https://en.wikipedia.org/wiki/Percent-encoding#Percent-encoding_reserved_characters|"%HH"] escapes for special characters in the userid.
For example "/" would be replaced by "%2F" meaning that a userid of "Projects/Budget" would become "Projects%2FBudget")
If you are behind a restrictive firewall, you might need
to <a href="#proxy">specify an HTTP proxy</a>.
A Fossil repository is a single disk file. Instead of cloning,
you can just make a copy of the repository file (for example, using
"scp"). Note, however, that the repository file contains auxiliary
information above and beyond the versioned files, including some
sensitive information such as password hashes and email addresses. If you
want to share Fossil repositories directly by copying, consider running the
[/help/scrub|fossil scrub] command to remove sensitive information
before transmitting the file.
<h2 id="import">Importing From Another Version Control System</h2>
Rather than start a new project, or clone an existing Fossil project,
you might prefer to
<a href="./inout.wiki">import an existing Git project</a>
into Fossil using the [/help/import | fossil import] command.
You can even decide to export your project back into git using the
[/help/git | fossil git] command, which is how the Fossil project maintains
[https://github.com/drhsqlite/fossil-mirror | its public GitHub mirror]. There
is no limit to the number of times a tree can be imported and exported between
Fossil and git.
The [https://git-scm.com/docs/git-fast-export|Git fast-export format] has become
a popular way to move files between version management systems, including from
[https://www.mercurial-scm.org/|Mercurial].
Fossil can also import [https://subversion.apache.org/|Subversion projects] directly.
<h2 id="checkout">Checking Out A Local Tree</h2>
To work on a project in fossil, you need to check out a local
copy of the source tree. Create the directory you want to be
the root of your tree and cd into that directory. Then
do this: ([/help/open | more info])
<pre><b>fossil open</b> <i>repository-filename</i></pre>
for example:
<pre><b>fossil open ../myclone.fossil
BUILD.txt
COPYRIGHT-BSD2.txt
README.md
︙
</tt></b></pre>
(or "fossil open ..\myclone.fossil" on Windows).
This leaves you with the newest version of the tree
checked out.
From anywhere underneath the root of your local tree, you
can type commands like the following to find out the status of
your local tree:
<pre>
<b>[/help/info | fossil info]</b>
<b>[/help/status | fossil status]</b>
<b>[/help/changes | fossil changes]</b>
<b>[/help/diff | fossil diff]</b>
<b>[/help/timeline | fossil timeline]</b>
<b>[/help/ls | fossil ls]</b>
<b>[/help/branch | fossil branch]</b>
</pre>
If you created a new repository using "fossil init" some commands will not
produce much output.
Note that Fossil allows you to make multiple check-outs in
separate directories from the same repository. This enables you,
for example, to do builds from multiple branches or versions at
the same time without having to generate extra clones.
To switch a checkout between different versions and branches,
use:<
<pre>
<b>[/help/update | fossil update]</b>
<b>[/help/checkout | fossil checkout]</b>
</pre>
[/help/update | update] honors the "autosync" option and
does a "soft" switch, merging any local changes into the target
version, whereas [/help/checkout | checkout] does not
automatically sync and does a "hard" switch, overwriting local
changes if told to do so.
<h2 id="changes">Making and Committing Changes</h2>
To add new files to your project or remove existing ones, use these
commands:
<pre>
<b>[/help/add | fossil add]</b> <i>file...</i>
<b>[/help/rm | fossil rm]</b> <i>file...</i>
<b>[/help/addremove | fossil addremove]</b> <i>file...</i>
</pre>
The command:
<pre><b>[/help/changes | fossil changes]</b></pre>
lists files that have changed since the last commit to the repository. For
example, if you edit the file "README.md":
<pre><b>fossil changes
EDITED README.md
</b></pre>
To see exactly what change was made you can use the command
<b>[/help/diff | fossil diff]</b>:
<pre><b>fossil diff

"fossil diff" shows the difference between your tree on disk now and as
the tree was when you last committed changes. If you haven't committed
yet, then it shows the difference relative to the tip-of-trunk commit in
the repository, being what you get when you "fossil open" a repository
without specifying a version, populating the working directory.
To see the most recent changes made to the repository by other users, use "fossil timeline" to
find out the most recent commit, and then "fossil diff" between that commit and the

You will be prompted for check-in comments using whatever editor
is specified by your VISUAL or EDITOR environment variable. If none is
specified Fossil uses line-editing in the terminal.
To commit your changes to a repository that was cloned from a remote
repository, you give the same command, but the results are different.
Fossil defaults to [./concepts.wiki#workflow|autosync] mode, a
single-stage commit that sends all changes committed to the local
repository immediately on to the remote parent repository. This only
works if you have write permission to the remote respository.
<h2 id="naming">Naming of Files, Checkins, and Branches</h2>
Fossil deals with information artifacts. This Quickstart document only deals
with files and collections of files, but be aware there are also tickets, wiki pages and more.
Every artifact in Fossil has a universally-unique hash id, and may also have a
human-readable name.
The following are all equivalent ways of identifying a Fossil file,
checkin or branch artifact:
<ul>
<li> the full unique SHA-256 hash, such as be836de35a821523beac2e53168e135d5ebd725d7af421e5f736a28e8034673a
<li> an abbreviated hash prefix, such as the first ten characters: be836de35a . This won't be universally unique, but it is usually unique within any one repository. As an example, the [https://fossil-scm.org/home/hash-collisions|Fossil project hash collisions] showed at the time of writing that there are no artifacts with identical first 8 characters
<li> a branch name, such as "special-features" or "juliet-testing". Each branch also has a unique SHA-256 hash
</ul>
A special convenience branch is "trunk", which is Fossil's default branch name for
the first checkin, and the default for any time a branch name is needed but not
specified.
This will get you started on identifying checkins. The
<a href="./checkin_names.wiki">Checkin Names document</a> is a complete reference, including
how timestamps can also be used.
<h2 id="config">Configuring Your Local Repository</h2>
When you create a new repository, either by cloning an existing
project or create a new project of your own, you usually want to do some
local configuration. This is easily accomplished using the web-server
that is built into fossil. Start the fossil web server like this:
([/help/ui | more info])
<pre>
<b>fossil ui</b> <i>repository-filename</i>
</pre>
You can omit the <i>repository-filename</i> from the command above
if you are inside a checked-out local tree.
This starts a web server then automatically launches your
web browser and makes it point to this web server. If your system
has an unusual configuration, fossil might not be able to figure out
how to start your web browser. In that case, first tell fossil
where to find your web browser using a command like this:
<pre>
<b>fossil setting web-browser</b> <i>path-to-web-browser</i>
</pre>
By default, fossil does not require a login for HTTP connections
coming in from the IP loopback address 127.0.0.1. You can, and perhaps
should, change this after you create a few users.
When you are finished configuring, just press Control-C or use
the <b>kill</b> command to shut down the mini-server.
<h2 id="sharing">Sharing Changes</h2>
When [./concepts.wiki#workflow|autosync] is turned off,
the changes you [/help/commit | commit] are only
on your local repository.
To share those changes with other repositories, do:
<pre>
<b>[/help/push | fossil push]</b> <i>URL</i>
</pre>
Where <i>URL</i> is the http: URL of the server repository you
want to share your changes with. If you omit the <i>URL</i> argument,
fossil will use whatever server you most recently synced with.
The [/help/push | push] command only sends your changes to others. To
Receive changes from others, use [/help/pull | pull]. Or go both ways at
once using [/help/sync | sync]:
<pre>
<b>[/help/pull | fossil pull]</b> <i>URL</i>
<b>[/help/sync | fossil sync]</b> <i>URL</i>
</pre>
When you pull in changes from others, they go into your repository,
not into your checked-out local tree. To get the changes into your
local tree, use [/help/update | update]:
<pre>
<b>[/help/update | fossil update]</b> <i>VERSION</i>
</pre>
The <i>VERSION</i> can be the name of a branch or tag or any
abbreviation to the 40-character
artifact identifier for a particular check-in, or it can be a
date/time stamp. ([./checkin_names.wiki | more info])
If you omit
the <i>VERSION</i>, then fossil moves you to the
latest version of the branch you are currently on.
The default behavior is for [./concepts.wiki#workflow|autosync] to
be turned on. That means that a [/help/pull|pull] automatically occurs
when you run [/help/update|update] and a [/help/push|push] happens
automatically after you [/help/commit|commit]. So in normal practice,
the push, pull, and sync commands are rarely used. But it is important
to know about them, all the same.
<pre>
<b>[/help/checkout | fossil checkout]</b> <i>VERSION</i>
</pre>
Is similar to update except that it does not honor the autosync
setting, nor does it merge in local changes - it prefers to overwrite
them and fails if local changes exist unless the <tt>--force</tt>
flag is used.
<h2 id="branch" name="merge">Branching And Merging</h2>
Use the --branch option to the [/help/commit | commit] command
to start a new branch. Note that in Fossil, branches are normally
created when you commit, not before you start editing. You can
use the [/help/branch | branch new] command to create a new branch
before you start editing, if you want, but most people just wait
until they are ready to commit.
To merge two branches back together, first
[/help/update | update] to the branch you want to merge into.
Then do a [/help/merge|merge] of the other branch that you want to incorporate
the changes from. For example, to merge "featureX" changes into "trunk"
do this:
<pre>
<b>fossil [/help/update|update] trunk</b>
<b>fossil [/help/merge|merge] featureX</b>
<i># make sure the merge didn't break anything...</i>
<b>fossil [/help/commit|commit]
</pre>
The argument to the [/help/merge|merge] command can be any of the
version identifier forms that work for [/help/update|update].
([./checkin_names.wiki|more info].)
The merge command has options to cherry-pick individual
changes, or to back out individual changes, if you don't want to
do a full merge.
The merge command puts all changes in your working check-out.
No changes are made to the repository.
You must run [/help/commit|commit] separately
to add the merge changes into your repository to make them persistent
and so that your coworkers can see them.
But before you do that, you will normally want to run a few tests
to verify that the merge didn't cause logic breaks in your code.
The same branch can be merged multiple times without trouble. Fossil
automatically keeps up with things and avoids conflicts when doing
multiple merges. So even if you have merged the featureX branch
into trunk previously, you can do so again and Fossil will automatically
know to pull in only those changes that have occurred since the previous
merge.
If a merge or update doesn't work out (perhaps something breaks or
there are many merge conflicts) then you back up using:
<pre>
<b>[/help/undo | fossil undo]</b>
</pre>
This will back out the changes that the merge or update made to the
working checkout. There is also a [/help/redo|redo] command if you undo by
mistake. Undo and redo only work for changes that have
not yet been checked in using commit and there is only a single
level of undo/redo.
<h2 id="server">Setting Up A Server</h2>
Fossil can act as a stand-alone web server using one of these
commands:
<pre>
<b>[/help/server | fossil server]</b> <i>repository-filename</i>
<b>[/help/ui | fossil ui]</b> <i>repository-filename</i>
</pre>
The <i>repository-filename</i> can be omitted when these commands
are run from within an open check-out, which is a particularly useful
shortcut with the <b>fossil ui</b> command.
The <b>ui</b> command is intended for accessing the web user interface
from a local desktop. (We sometimes call this mode "Fossil UI.")
The <b>ui</b> command differs from the
<b>server</b> command by binding to the loopback IP
address only (thus making the web UI visible only on the
local machine) and by automatically starting your default web browser,
pointing it at the running UI
server. The localhost restriction exists because it also gives anyone
who can access the resulting web UI full control over the
repository. (This is the [./caps/admin-v-setup.md#apsu | all-powerful
Setup capabliity].)
For cross-machine collaboration, use the <b>server</b> command instead,
which binds on all IP addresses, does not try to start a web browser,
and enforces [./caps/ | Fossil's role-based access control system].
Servers are also easily configured as:
<ul>
<li>[./server/any/inetd.md|inetd]
<li>[./server/debian/service.md|systemd]
<li>[./server/any/cgi.md|CGI]
<li>[./server/any/scgi.md|SCGI]
</ul>
…along with [./server/#matrix | several other options].
The [./selfhost.wiki | self-hosting fossil repositories] use
CGI.
You might <i>need</i> to set up a server, whether you know it yet or
not. See the [./server/whyuseaserver.wiki | Benefits of a Fossil Server]
article for details.
<h2 id="proxy">HTTP Proxies</h2>
If you are behind a restrictive firewall that requires you to use
an HTTP proxy to reach the internet, then you can configure the proxy
in three different ways. You can tell fossil about your proxy using
a command-line option on commands that use the network,
<b>sync</b>, <b>clone</b>, <b>push</b>, and <b>pull</b>.
<pre>
<b>fossil clone </b><i>URL</i> <b>--proxy</b> <i>Proxy-URL</i>
</pre>
It is annoying to have to type in the proxy URL every time you
sync your project, though, so you can make the proxy configuration
persistent using the [/help/setting | setting] command:
<pre>
<b>fossil setting proxy </b><i>Proxy-URL</i>
</pre>
Or, you can set the "<b>http_proxy</b>" environment variable:
<pre>
<b>export http_proxy=</b><i>Proxy-URL</i>
</pre>
To stop using the proxy, do:
<pre>
<b>fossil setting proxy off</b>
</pre>
Or unset the environment variable. The fossil setting for the
HTTP proxy takes precedence over the environment variable and the
command-line option overrides both. If you have a persistent
proxy setting that you want to override for a one-time sync, that
is easily done on the command-line. For example, to sync with
a co-worker's repository on your LAN, you might type:
<pre>
<b>fossil sync http://192.168.1.36:8080/ --proxy off</b>
</pre>

# Rebase Considered Harmful
Fossil deliberately omits a "rebase" command because the original
designer of Fossil (and [original author][vhist] of this article) considers rebase to be
an anti-pattern to be avoided. This article attempts to
explain that point of view.
[vhist]: /finfo?name=www/rebaseharm.md&ubg
## 1.0 Rebasing is dangerous
Most people, even strident advocates of rebase, agree that rebase can
cause problems when misused. The Git rebase documentation talks about the
[golden rule of rebasing][golden]: never rebase on a public
branch. Horror stories of misused rebase abound, and the rebase
documentation devotes considerable space toward explaining how to
recover from rebase errors and/or misuse.
## <a id="cap-loss"></a>2.0 Rebase provides no new capabilities
Sometimes sharp and dangerous tools are justified,
because they accomplish things that cannot be
done otherwise, or at least cannot be done easily.
Rebase does not fall into that category,
because it provides no new capabilities.
### <a id="orphaning"></a>2.1 A rebase is just a merge with historical references omitted
A rebase is really nothing more than a merge (or a series of merges)
that deliberately forgets one of the parents of each merge step.
To help illustrate this fact,
consider the first rebase example from the
[Git documentation][gitrebase]. The merge looks like this:
~~~ pikchr toggle center
scale = 0.8
circle "C0" fit
arrow right 50%
circle same "C1"
arrow same
circle same "C2"
arrow same
circle same "C3"
arrow same
circle same "C5"
circle same "C4" at 1cm above C3
arrow from C2 to C4 chop
arrow from C4 to C5 chop
~~~
And the rebase looks like this:
~~~ pikchr toggle center
scale = 0.8
circle "C0" fit
arrow right 50%
circle same "C1"
arrow same
circle same "C2"
arrow same
circle same "C3"
arrow same
circle same "C4'"
circle same "C4" at 1cm above C3
arrow from C2 to C4 chop
~~~
As the [Git documentation][gitrebase] points out, check-ins C4\' and C5
are identical. The only difference between C4\' and C5 is that C5
records the fact that C4 is its merge parent but C4\' does not.
Thus, a rebase is just a merge that forgets where it came from.
The Git documentation acknowledges this fact (in so many words) and
justifies it by saying "rebasing makes for a cleaner history." I read
that sentence as a tacit admission that the Git history display
capabilities are weak and need active assistance from the user to
keep things manageable.
Surely a better approach is to record
the complete ancestry of every check-in but then fix the tool to show
a "clean" history in those instances where a simplified display is
desirable and edifying, but retain the option to show the real,
complete, messy history for cases where detail and accuracy are more
important.
So, another way of thinking about rebase is that it is a kind of
merge that intentionally forgets some details in order to
not overwhelm the weak history display mechanisms available in Git.
Wouldn't it be better, less error-prone, and easier on users
to enhance the history display mechanisms in Git so that rebasing
for a clean, linear history became unnecessary?
### <a id="clean-diffs"></a>2.2 Rebase does not actually provide better feature-branch diffs
Another argument, often cited, is that rebasing a feature branch
allows one to see just the changes in the feature branch without
the concurrent changes in the main line of development.
Consider a hypothetical case:
~~~ pikchr toggle center
scale = 0.8
circle "C0" fit fill white
arrow right 50%
circle same "C1"
arrow same
circle same "C2"
arrow same
circle same "C4"
arrow same
circle same "C6"
circle same "C3" at last arrow.width + C0.rad*2 heading 30 from C2
arrow right 50%
circle same "C5"
arrow from C2 to C3 chop
box ht C3.y-C2.y wid C6.e.x-C0.w.x+1.5*C1.rad at C2 behind C0 fill 0xc6e2ff color 0xaac5df
box ht previous.ht wid previous.wid*0.55 with .se at previous.ne \
behind C0 fill 0x9accfc color 0xaac5df
text "feature" with .s at previous.n
text "main" with .n at first box.s
~~~
In the above, a feature branch consisting of check-ins C3 and C5 is
run concurrently with the main line in check-ins C4 and C6. Advocates
for rebase say that you should rebase the feature branch to the tip
of main in order to remove main-line development differences from
the feature branch's history:
~~~ pikchr toggle center
# Duplicated below in section 5.0
scale = 0.8
circle "C0" fit fill white
arrow right 50%
circle same "C1"
arrow same
circle same "C2"
arrow same
circle same "C4"
arrow same
circle same "C6"
circle same "C3" at last arrow.width + C0.rad*2 heading 30 from C2
arrow right 50%
circle same "C5"
arrow from C2 to C3 chop
C3P: circle same "C3'" at first arrow.width + C0.rad*2 heading 30 from C6
arrow right 50% from C3P.e
C5P: circle same "C5'"
arrow from C6 to C3P chop
box ht C3.y-C2.y wid C5P.e.x-C0.w.x+1.5*C1.rad with .w at 0.5*(first arrow.wid) west of C0.w \
behind C0 fill 0xc6e2ff color 0xaac5df
box ht previous.ht wid previous.e.x - C2.w.x with .se at previous.ne \
behind C0 fill 0x9accfc color 0xaac5df
~~~
You could choose to collapse C3\' and C5\' into a single check-in
as part of this rebase, but that's a side issue we'll deal with
[separately](#collapsing).
Because Fossil purposefully lacks rebase, the closest you can get to this same check-in
history is the following merge:
~~~ pikchr toggle center
scale = 0.8
circle "C0" fit fill white
arrow right 50%
circle same "C1"
arrow same
circle same "C2"
arrow same
circle same "C4"
arrow same
circle same "C6"
circle same "C3" at last arrow.width + C0.rad*2 heading 30 from C2
arrow right 50%
circle same "C5"
arrow same
circle same "C7"
arrow from C2 to C3 chop
arrow from C6 to C7 chop
box ht C3.y-C2.y wid C7.e.x-C0.w.x+1.5*C1.rad with .w at 0.5*(first arrow.wid) west of C0.w \
behind C0 fill 0xc6e2ff color 0xaac5df
box ht previous.ht wid previous.e.x - C2.w.x with .se at previous.ne \
behind C0 fill 0x9accfc color 0xaac5df
~~~
Check-ins C5\' and C7 check-ins hold identical code. The only
difference is in their history.
The argument from rebase advocates
is that with merge it is difficult to see only the changes associated
with the feature branch without the commingled mainline changes.
In other words, diff(C2,C7) shows changes from both the feature
branch and from the mainline, whereas in the rebase case
diff(C6,C5\') shows only the feature branch changes.
But that argument is comparing apples to oranges, since the two diffs
do not have the same baseline. The correct way to see only the feature
branch changes in the merge case is not diff(C2,C7) but rather diff(C6,C7).
<div align=center>
| Rebase | Merge | What You See |
|---------------|-------------|----------------------------------------|
| diff(C2,C5\') | diff(C2,C7) | Commingled branch and mainline changes |
| diff(C6,C5\') | diff(C6,C7) | Branch changes only |
</div>
Remember: C7 and C5\' are bit-for-bit identical, so the output of the
diff is not determined by whether you select C7 or C5\' as the target
of the diff, but rather by your choice of the diff source, C2 or C6.
So, to help with the problem of viewing changes associated with a feature
branch, perhaps what is needed is not rebase but rather better tools to
help users identify an appropriate baseline for their diffs.
## <a id="siloing"></a>3.0 Rebase encourages siloed development
The [golden rule of rebasing][golden] is that you should never do it
on public branches, so if you are using rebase as intended, that means
you are keeping private branches. Or, to put it another way, you are
doing siloed development. You are not sharing your intermediate work
with collaborators. This is not good for product quality.
[Nagappan, et. al][nagappan] studied bugs in Windows Vista and found
that the best predictor of bugs is the distance on the org-chart between
the stake-holders. The bug rate is inversely related to the
amount of communication among the engineers.
Similar findings arise in other disciplines. Keeping
private branches does not prove that developers are communicating
insufficiently, but it is a key symptom of that problem.
[Weinberg][weinberg] argues programming should be "egoless." That
is to say, programmers should avoid linking their code with their sense of
self, as that makes it more difficult for them to find and respond
to bugs, and hence makes them less productive. Many developers are
drawn to private branches out of sense of ego. "I want to get the
code right before I publish it." I sympathize with this sentiment,
and am frequently guilty of it myself. It is humbling to display
your stupid mistake to the whole world on an Internet that
never forgets. And yet, humble programmers generate better code.
What is the fastest path to solid code? Is it to continue staring at
your private branch to seek out every last bug, or is it to publish it
as-is, whereupon the many eyeballs will immediately see that last stupid
error in the code? Testing and development are often done by separate
groups within a larger software development organization, because
developers get too close to their own code to see every problem in it.
Given that, is it better for those many eyeballs to find your problems
while they're still isolated on a feature branch, or should that vetting
wait until you finally push a collapsed version of a private working
branch to the parent repo? Will the many eyeballs even see those errors
when they’re intermingled with code implementing some compelling new feature?
## <a id="timestamps"></a>4.0 Rebase causes timestamp confusion
Consider the earlier example of rebasing a feature branch:
~~~ pikchr toggle center
# Copy of second diagram in section 2.2 above
scale = 0.8
circle "C0" fit fill white
arrow right 50%
circle same "C1"
arrow same
circle same "C2"
arrow same
circle same "C4"
arrow same
circle same "C6"
circle same "C3" at last arrow.width + C0.rad*2 heading 30 from C2
arrow right 50%
circle same "C5"
arrow from C2 to C3 chop
C3P: circle same "C3'" at first arrow.width + C0.rad*2 heading 30 from C6
arrow right 50% from C3P.e
C5P: circle same "C5'"
arrow from C6 to C3P chop
box ht C3.y-C2.y wid C5P.e.x-C0.w.x+1.5*C1.rad with .w at 0.5*(first arrow.wid) west of C0.w \
behind C0 fill 0xc6e2ff color 0xaac5df
box ht previous.ht wid previous.e.x - C2.w.x with .se at previous.ne \
behind C0 fill 0x9accfc color 0xaac5df
~~~
What timestamps go on the C3\' and C5\' check-ins? If you choose
the same timestamps as the original C3 and C5, then you have the
odd situation C3' is older than its parent C6. We call that a
"timewarp" in Fossil. Timewarps can also happen due to misconfigured
system clocks, so they are not unique to rebase, but they are very
confusing and so best avoided. The other option is to provide new
unique timestamps for C3' and C5' but then you lose the information
about when those check-ins were originally created, which can make
historical analysis of changes more difficult. It might also
complicate the legal defense of prior art claims.
## <a id="lying"></a>5.0 Rebase misrepresents the project history
By discarding parentage information, rebase attempts to deceive the
reader about how the code actually came together.
Git’s rebase feature is more than just an
alternative to merging: it also provides mechanisms for changing the
project history in order to make editorial changes. Fossil shows that
you can get similar effects without modifying historical records,
allowing users to:
1. Edit check-in comments to fix typos or enhance clarity
2. Attach supplemental notes to check-ins or whole branches
3. Hide ill-conceived or now-unused branches from routine display
4. Fix faulty check-in date/times resulting from misconfigured
system clocks
5. Cross-reference check-ins with each other, or with
wiki, tickets, forum posts, and/or embedded documentation
…and so forth.
Fossil allows all of this not by removing or modifying existing
repository entries, but rather by adding new supplemental records.
Fossil keeps the original incorrect or unclear inputs and makes them
readily accessible, preserving the original historical record. Fossil
doesn’t make the user tell counter-factual “stories,†it only allows the
user to provide annotations to provide a more readable edited
presentation for routine display purposes.
Git needs rebase because it lacks these annotation facilities. Rather
than consider rebase a desirable feature missing in Fossil, ask instead
why Git lacks support for making editorial changes to check-ins without
modifying history? Wouldn't it be better to fix the version control
tool rather than requiring users to fabricate a fictitious project
history?
## <a id="collapsing"></a>6.0 Collapsing check-ins throws away valuable information
One of the oft-cited advantages of rebasing in Git is that it lets you
collapse multiple check-ins down to a single check-in to make the
development history “clean.†The intent is that development appear as
though every feature were created in a single step: no multi-step
evolution, no back-tracking, no false starts, no mistakes. This ignores
actual developer psychology: ideas rarely spring forth from fingers to
files in faultless finished form. A wish for collapsed, finalized
check-ins is a wish for a counterfactual situation.
The common counterargument is that collapsed check-ins represent a
better world, the ideal we're striving for. What that argument overlooks
is that we must throw away valuable information to get there.
### <a id="empathy"></a>6.1 Individual check-ins support mutual understanding
Ideally, future developers of our software can understand every feature
in it using only context available in the version of the code they start
work with. Prior to widespread version control, developers had no choice
but to work that way. Pre-existing codebases could only be understood
as-is or not at all. Developers in that world had an incentive to
develop software that was easy to understand retrospectively, even if
they were selfish people, because they knew they might end up being
those future developers!
Yet, sometimes we come upon a piece of code that we simply cannot
understand. If you have never asked yourself, "What was this code's
developer thinking?" you haven't been developing software for very long.
When a developer can go back to the individual check-ins leading up to
the current code, they can work out the answers to such questions using
only the level of personal brilliance necessary to be a good developer. To
understand such code using only the finished form, you are asking future
developers to make intuitive leaps that the original developer was
unable to make. In other words, you are asking your future maintenance
developers to be smarter than the original developers! That's a
beautiful wish, but there's a sharp limit to how far you can carry it.
Eventually you hit the limits of human brilliance.
When the operation of some bit of code is not obvious, both Fossil and
Git let you run a [`blame`](/help?cmd=blame) on the code file to get
information about each line of code, and from that which check-in last
touched a given line of code. If you squash the check-ins on a branch
down to a single check-in, you throw away the information leading up to
that finished form. Fossil not only preserves the check-ins surrounding
the one that included the line of code you're trying to understand, its
[superior data model][sdm] lets you see the surrounding check-ins in
both directions; not only what lead up to it, but what came next. Git
can't do that short of crawling the block-chain backwards from the tip
of the branch to the check-in you’re looking at, an expensive operation.
We believe it is easier to understand a line of code from the 10-line
check-in it was a part of — and then to understand the surrounding
check-ins as necessary — than it is to understand a 500-line check-in
that collapses a whole branch's worth of changes down to a single
finished feature.
[sdm]: ./fossil-v-git.wiki#durable
### <a id="bisecting"></a>6.2 Bisecting works better on small check-ins
Git lets a developer write a feature in ten check-ins but collapse it
down to an eleventh check-in and then deliberately push only that final
collapsed check-in to the parent repo. Someone else may then do a bisect
that blames the merged check-in as the source of the problem they’re
chasing down; they then have to manually work out which of the 10 steps
the original developer took to create it to find the source of the
actual problem.
An equivalent push in Fossil will send all 11 check-ins to the parent
repository so that a later investigator doing the same sort of bisect
sees the complete check-in history. That bisect will point the
investigator at the single original check-in that caused the problem.
### <a id="comments"></a>6.3 Multiple check-ins require multiple check-in comments
The more comments you have from a given developer on a given body of
code, the more concise documentation you have of that developer's
thought process. To resume the bisecting example, a developer trying to
work out what the original developer was thinking with a given change
will have more success given a check-in comment that explains what the
one check-in out of ten blamed by the "bisect" command was trying to
accomplish than if they must work that out from the eleventh check-in's
comment, which only explains the "clean" version of the collapsed
feature.
### <a id="cherrypicking"></a>6.4 Cherry-picks work better with small check-ins
While working on a new feature in one branch, you may come across a bug
in the pre-existing code that you need to fix in order for work on that
feature to proceed. You could choose to switch briefly back to the
parent branch, develop the fix there, check it in, then merge the parent
back up to the feature branch in order to continue work, but that's
distracting. If the fix isn't for a critical bug, fixing it on the
parent branch can wait, so it's better to maintain your mental working
state by fixing the problem in place on the feature branch, then check
the fix in on the feature branch, resume work on the feature, and later
merge that fix down into the parent branch along with the feature.
But now what happens if another branch *also* needs that fix? Let us say
our code repository has a branch for the current stable release, a
development branch for the next major version, and feature branches off
of the development branch. If we rebase each feature branch down into
the development branch as a single check-in, pushing only the rebase
check-in up to the parent repo, only that fix's developer has the
information locally to perform the cherry-pick of the fix onto the
stable branch.
Developers working on new features often do not care about old stable
versions, yet that stable version may have an end user community that
depends on that version, who either cannot wait for the next stable
version or who wish to put off upgrading to it for some time. Such users
want backported bug fixes, yet the developers creating those fixes have
poor incentives to provide those backports. Thus the existence of
maintenance and support organizations, who end up doing such work.
(There is [a famous company][rh] that built a multi-billion dollar
enterprise on such work.)
This work is far easier when each cherry-pick transfers completely and
cleanly from one branch to another, and we increase the likelihood of
achieving that state by working from the smallest check-ins that remain
complete. If a support organization must manually disentangle a fix from
a feature check-in, they are likely to introduce new bugs on the stable
branch. Even if they manage to do their work without error, it takes
them more time to do the cherry-pick that way.
[rh]: https://en.wikipedia.org/wiki/Red_Hat
### <a id="backouts"></a>6.5 Back-outs also work better with small check-ins
The inverse of the cherry-pick merge is the back-out merge. If you push
only a collapsed version of a private working branch up to the parent
repo, those working from that parent repo cannot automatically back out
any of the individual check-ins that went into that private branch.
Others must either manually disentangle the problematic part of your
merge check-in or back out the entire feature.
## <a id="better-plan"></a>7.0 Cherry-pick merges work better than rebase
Perhaps there are some cases where a rebase-like transformation
is actually helpful, but those cases are rare, and when they do
come up, running a series of cherry-pick merges achieves the same
topology with several advantages:
1. In Fossil, cherry-pick merges preserve an honest and clear record
of history. Fossil remembers where a cherry-pick came from, and
it shows this in its timeline, so other developers can understand
how a cherry-pick based commit came together.
Git lacks the ability to remember the source of a cherry-pick as
part of the commit. This fact has no direct bearing on this
document’s thesis, but we can make a few observations. First, Git
forgets history in more cases than in rebasing. Second, if Git
remembered the source of cherry-picks in commits, Git users might
have a better argument for avoiding rebase, because they’d have an
alternative that *didn’t* lose history.
2. Fossil’s [test before commit philosophy][tbc] means you can test a
cherry-pick before committing it. Because Fossil allows multiple
cherry-picks in a single commit and it remembers them all, you can
do this for a complicated merge in step-wise fashion.
Git commits cherry-picks straight to the repository, so that if it
results in a bad state, you have to do something drastic like
`git reset --hard` to repair the damage.
3. Cherry-picks keep both the original and the revised check-ins,
so both timestamps are preserved.

## <a id="conclusion"></a>8.0 Summary and conclusion
Rebasing is an anti-pattern. It is dishonest. It deliberately
omits historical information. It causes problems for collaboration.
And it has no offsetting benefits.
For these reasons, rebase is intentionally and deliberately omitted
from the design of Fossil.

The reasons I use fossil are that it's the only version control I
have found that I can get working through the VERY annoying MS
firewalls at work.. (albeit through an ntlm proxy) and I just love
single .exe applications!

With one of my several hats on, I'm in a small team using git. Another
team member just checked some stuff into trunk that should have been on
a branch. Nothing else had happened since, so in fossil I would have
just edited that commit and put it on a new branch. In git that can't
actually be done without danger once other people have pulled, so I had
to create a new commit rolling back the changes, then branch and cherry
pick the earlier changes, then figure out how to make my new branch
shared instead of private. Just want to say thanks for fossil making my
life easier on most of my projects, and being able to move commits to
another branch after the fact and shared-by-default branches are good
features. Also not having a misanthropic command line interface.

<div class="indent">
Sometime in late 2007 I came across a link to fossil on
<a href="http://www.sqlite.org/">sqlite.org</a>. It
was a good thing I bookmarked it, because I was never able to find the
link again (it might have been in a bug report or something). The
reasons I first took a close look at it were (A) it stemmed from the
sqlite project, which I've held in high regards for years (e.g. I
wrote JavaScript bindings for it:
<a href="http://spiderape.sourceforge.net/plugins/sqlite/">
http://spiderape.sourceforge.net/plugins/sqlite/</a>), and (B) it could
run as a CGI. That second point might seem a bit archaic, but in
practice CGI is the only way most hosted sites can set up a shared
source repository with multiple user IDs. (i'm not about to give out
my only account password or SSH key for my hosted sites, no matter how
much I trust the other developers, and none of my hosters allow me to
run standalone servers or add Apache modules.)
So I tried it out. The thing which bugged me most about it was having
to type "commit" or "com" instead of "ci" for checking in (as is
custom in all other systems I've used), despite the fact that fossil
uses "ci" as a filter in things like the timeline view. Looking back
now, I have used fossil for about about 95% of my work in the past
year (<a href="http://blog.s11n.net/?p=71"><i>dead link</i></a>), in
over 15 source trees, and I now get tripped up when I have to use svn or cvs.
So, having got over typing "fossil com -m ...", here's why I love it so much...
Point #1: CGI
Again, this sounds archaic, but fossil has allowed me to share source
trees which I cannot justifiably host in other projects I work on

In summary: I remember my first reaction to fossil being, "this will be an excellent solution for small projects (like the dozens we've all got sitting on our hard drives but which don't justify the hassle of version control)." A year of daily use in over 15 source trees has confirmed that, and I continue to heartily recommend fossil to other developers I know who also have their own collection of "unhosted" pet projects. </div> |

<title>Fossil SCGI</title>
To run Fossil using SCGI, start the [/help/server|fossil server] command
with the --scgi command-line option. You will probably also want to
specific an alternative TCP/IP port using --port. For example:
<pre>
fossil server $REPOSITORY --port 9000 --scgi
</pre>
Then configure your SCGI-aware web-server to send SCGI requests to port
9000 on the machine where Fossil is running. A typical configuration for
this in Nginx is:
<pre>
location ~ ^/demo_project/ {
include scgi_params;
scgi_pass localhost:9000;
scgi_param SCRIPT_NAME "/demo_project";
scgi_param HTTPS "on";
}
</pre>
Note that Nginx does not normally send either the PATH_INFO or SCRIPT_NAME
variables via SCGI, but Fossil needs one or the other. So the configuration
above needs to add SCRIPT_NAME. If you do not do this, Fossil returns an
error.

This note describes the defensive measures that Fossil uses to help prevent information loss due to bugs. Fossil has been hosting itself and many other projects for years now. Many bugs have been encountered. But, thanks in large part to the defensive measures described here, no data has been lost. The integrity checks are doing their job well.</p> <h2>Atomic Check-ins With Rollback</h2> The Fossil repository is stored in an <a href="http://www.sqlite.org/">SQLite</a> database file. ([./tech_overview.wiki | Additional information] about the repository file format.) SQLite is very mature and stable and has been in wide-spread use for many years, so we are confident it will not cause repository corruption. SQLite databases do not corrupt even if a program or system crash or power failure occurs in the middle of the update. If some kind of crash does occur in the middle of a change, then all the changes are rolled back the next time that the database is accessed. A check-in operation in Fossil makes many changes to the repository database. But all these changes happen within a single transaction. If something goes wrong in the middle of the commit, even if that something is a power failure or OS crash, then the transaction is rolled back and the database is unchanged. <h2>Verification Of Delta Encodings Prior To Transaction Commit</h2> The content files that comprise the global state of a Fossil repository are stored in the repository as a tree. The leaves of the tree are stored as zlib-compressed BLOBs. Interior nodes are deltas from their descendants. A lot of encoding is going on. There is zlib-compression which is relatively well-tested but still might cause corruption if used improperly. And there is the relatively new [./delta_encoder_algorithm.wiki | delta-encoding mechanism] designed expressly for Fossil. We want to make sure that bugs in these encoding mechanisms do not lead to loss of data. To increase our confidence that everything in the repository is recoverable, Fossil makes sure it can extract an exact replica of every content file that it changes just prior to transaction commit. So during the course of check-in (or other repository operation) many different files in the repository might be modified. Some files are simply compressed. Other files are delta encoded and then compressed. While all this is going on, Fossil makes a record of every file and the SHA1 or SHA3-256 hash of the original content of that file. Then just before transaction commit, Fossil re-extracts the original content of all files that were written, recomputes the hash, and verifies that the recomputed hash still matches. If anything does not match up, an error message is printed and the transaction rolls back. So, in other words, Fossil always checks to make sure it can re-extract a file before it commits a change to that file. Hence bugs in Fossil are unlikely to corrupt the repository in a way that prevents us from extracting historical versions of files. <h2>Checksum Over All Files In A Check-in</h2> Manifest artifacts that define a check-in have two fields (the R-card and Z-card) that record MD5 hashes of the manifest itself and of all other files in the manifest. Prior to any check-in commit, these checksums are verified to ensure that the check-in agrees exactly with what is on disk. Similarly, the repository checksum is verified after a checkout to make sure that the entire repository was checked out correctly. Note that these added checks use a different hash algorithm (MD5) in order to avoid common-mode failures in the hash algorithm implementation. <h2>Checksums On Structural Artifacts And Deltas</h2> Every [./fileformat.wiki | structural artifact] in a Fossil repository contains a "Z-card" bearing an MD5 checksum over the rest of the artifact. Any mismatch causes the structural artifact to be ignored. The [./delta_format.wiki | file delta format] includes a 32-bit checksum of the target file. Whenever a file is reconstructed from a delta, that checksum is verified to make sure the reconstruction was done correctly. <h2>Reliability Versus Performance</h2> Some version control systems make a big deal out of being "high performance" or the "fastest version control system". Fossil makes no such claims and has no such ambition. Indeed, profiling indicates that Fossil bears a substantial performance cost for doing all of the checksumming and verification outlined above. Fossil takes the philosophy of the <a href="http://en.wikipedia.org/wiki/The_Tortoise_and_the_Hare">tortoise</a>: reliability is more important than raw speed. The developers of Fossil see no merit in getting the wrong answer quickly. Fossil may not be the fastest versioning system, but it is <i>fast enough</i>. Fossil runs quickly enough to stay out of the developer's way. Most operations complete in milliseconds, faster than you can press the "Enter" key. |

As of 2017-07-25 there are three publicly accessible repositories for the Fossil source code: 1. [https://fossil-scm.org/] 2. [https://www2.fossil-scm.org/] 3. [https://www3.fossil-scm.org/site.cgi] The canonical repository is (1). Repositories (2) and (3) automatically stay in synchronization with (1) via a <a href="http://en.wikipedia.org/wiki/Cron">cron job</a> that invokes "fossil sync" at regular intervals. Repository (2) also publishes a [https://github.com/drhsqlite/fossil-mirror|GitHub mirror of Fossil] as a demonstration of [./mirrortogithub.md|how that can be done]. Note that the two secondary repositories are more than just read-only mirrors. All three servers support full read/write capabilities. Changes (such as new tickets or wiki or check-ins) can be implemented on any of the three servers and those changes automatically propagate to the other two servers. Server (1) runs as a [./aboutcgi.wiki|CGI script] on a <a href="http://www.linode.com/">Linode 8192</a> located in Dallas, TX - on the same virtual machine that hosts <a href="http://www.sqlite.org/">SQLite</a> and over a dozen other smaller projects. This demonstrates that Fossil can run on a low-power host processor. Multiple fossil-based projects can easily be hosted on the same machine, even if that machine is itself one of several dozen virtual machines on a single physical box. The CGI script that runs the canonical Fossil self-hosting repository is as follows: <pre> #!/usr/bin/fossil repository: /fossil/fossil.fossil </pre> Server (3) ran for 10 years as a CGI script on a shared hosting account at <a href="http://www.he.net/">Hurricane Electric</a> in Fremont, CA. This server demonstrated the ability of Fossil to run on an economical shared-host web account with no privileges beyond port 80 HTTP access and CGI. It is not necessary to have a dedicated computer with administrator privileges to run Fossil. As far as we are aware, Fossil is the only full-featured configuration management system that can run in such a restricted environment. The CGI script that ran on the Hurricane Electric server was the same as the CGI script shown above, except that the pathnames are modified to suit the environment: <pre> #!/home/hwaci/bin/fossil repository: /home/hwaci/fossil/fossil.fossil </pre> In recent years, virtual private servers have become a more flexible and less expensive hosting option compared to shared hosting accounts. So on 2017-07-25, server (3) was moved onto a $5/month "droplet" [https://en.wikipedia.org/wiki/Virtual_private_server|VPS] from [https://www.digitalocean.com|Digital Ocean] located in San Francisco. Server (3) is synchronized with the canonical server (1) by running a command similar to the following via cron: <pre> /usr/local/bin/fossil all sync -u </pre> Server (2) is a <a href="http://www.linode.com/">Linode 4096</a> located in Newark, NJ and set up just like the canonical server (1) with the addition of a cron job for synchronization. The same cron job also runs the [/help?cmd=git|fossil git export] command after each sync in order to [./mirrortogithub.md#ex1|mirror all changes to GitHub]. |

# Serving via althttpd
[Althttpd][althttpd]
is a light-weight web server that has been used to implement the SQLite and
Fossil websites for well over a decade. Althttpd strives for simplicity,
security, ease of configuration, and low resource usage.
To set up a Fossil server as CGI on a host running the althttpd web
server, follow these steps.
<ol>
<li>Get the althttpd webserver running on the host. This is easily
done by following the [althttpd documentation][althttpd].
<li>Create a CGI script for your Fossil repository. The script will
be typically be two lines of code that look something like this:
~~~
#!/usr/bin/fossil
repository: /home/yourlogin/fossils/project.fossil
~~~
Modify the filenames to conform to your system, of course. The
CGI script accepts [other options][cgi] besides the
repository:" line. You can add in other options as you desire,
but the single "repository:" line is normally all that is needed
to get started.
<li>Make the CGI script executable.
<li>Verify that the fossil repository file and the directory that contains
the repository are both writable by whatever user the web server is
running and.
</ol>
And you are done. Visit the URL that corresponds to the CGI script
you created to start using your Fossil server.

# Serving via CGI
A Fossil server can be run from most ordinary web servers as a CGI
program. This feature allows Fossil to seamlessly integrate into a
larger website. The [self-hosting Fossil repository web
site](../../selfhost.wiki) is implemented using CGI. See the
[How CGI Works](../../aboutcgi.wiki) page for background information
on the CGI protocol.
To run Fossil as CGI, create a CGI script (here called "repo") in the
CGI directory of your web server with content like this:
#!/usr/bin/fossil
repository: /home/fossil/repo.fossil
Adjust the paths appropriately. It may be necessary to set certain
permissions on this file or to modify an `.htaccess` file or make other
server-specific changes. Consult the documentation for your particular
web server. The following permissions are *normally* required, but,
again, may be different for a particular configuration:
* The Fossil binary (`/usr/bin/fossil` in the example above)
must be readable/executable.
* *All* directories leading up to the Fossil binary must be readable
by the process which executes the CGI.
* The CGI script must be executable for the user under which it will
run, which often differs from the one running the web server.
Consult your site's documentation or the web server’s system
administrator.
* *All* directories leading to the CGI script must be readable by the
web server.
* The repository file *and* the directory containing it must be
writable by the same account which executes the Fossil binary.
(This might differ from the user the web server normally runs
under.) The directory holding the repository file(s) needs to be
writable so that SQLite can write its journal files. When using
another access control system, such as AppArmor or SELinux, it may
be necessary to explicitly permit that account to read and write
the necessary files.
* Fossil must be able to create temporary files in a
[directory that varies by host OS](../../env-opts.md#temp). When the
CGI process is operating [within a chroot](../../chroot.md),
ensure that this directory exists and is readable/writeable by the
user who executes the Fossil binary.
Once the CGI script is set up correctly, and assuming your server is
also set correctly, you should be able to access your repository with a
URL like: <b>http://mydomain.org/cgi-bin/repo</b> This is assuming you
are running a web server like Apache that uses a “`cgi-bin`†directory
for scripts like our “`repo`†example.
To serve multiple repositories from a directory using CGI, use the
"directory:" tag in the CGI script rather than "repository:". You
might also want to add a "notfound:" tag to tell where to redirect if
the particular repository requested by the URL is not found:
#!/usr/bin/fossil
directory: /home/fossil/repos
notfound: http://url-to-go-to-if-repo-not-found/
Once deployed, a URL like: <b>http://mydomain.org/cgi-bin/repo/XYZ</b>
will serve up the repository `/home/fossil/repos/XYZ.fossil` if it
exists.
Additional options available to the CGI script are [documented
separately](../../cgi.wiki).
#### CGI with Apache behind an Nginx proxy
For the case where the Fossil repositories live on a computer, itself behind
an Internet-facing machine that employs Nginx to reverse proxy HTTP(S) requests
and take care of the TLS part of the connections in a transparent manner for
the downstream web servers, the CGI parameter `HTTPS=on` might not be set.
However, Fossil in CGI mode needs it in order to generate the correct links.
Apache can be instructed to pass this parameter further to the CGI scripts for
TLS connections with a stanza like
SetEnvIf X-Forwarded-Proto "https" HTTPS=on
in its config file section for CGI, provided that
proxy_set_header X-Forwarded-Proto $scheme;
has been be added in the relevant proxying section of the Nginx config file.
*[Return to the top-level Fossil server article.](../)*
#### Apache mod_cgi and `CONTENT_LENGTH`
At some point in its 2.4.x family, Apache's `mod_cgi` stopped relaying
the Content-Length header in the HTTP reply from CGIs back to clients.
However, Fossil clients prior to 2024-04-17 depended on seeing the
Content-Length header and were unable to handle HTTP replies without
one. The change in Apache behavior caused "fossil clone" and "fossil
sync" to stop working. There are two possible fixes to this problem:
1. Restore legacy behavior in Apache by adding
the following to the Apache configuration, scoped to the `<Directory>`
entry or entries in which fossil is being served via CGI:
<blockquote><pre>
<Directory ...>
SetEnv ap_trust_cgilike_cl "yes"
</Directory>
</pre></blockquote>
2. Upgrade your Fossil client to any trunk check-in after 2024-04-17,
as Fossil was upgraded to be able to deal with the missing
Content-Length field by
[check-in a8e33fb161f45b65](/info/a8e33fb161f45b65).

# Forcing Use of Fossil’s RBAC over SSH
Andy Bradford posted a [clever solution][sshfc] to the problem of
Fossil’s RBAC system [being ignored](../../caps/#webonly) over `ssh://`
URLs: use OpenSSH’s `ForceCommand` feature to route the sync transfer
protocol data over `fossil http` rather than `fossil test-http`.
The setup for this is complicated, but it’s a worthy option when you
need encrypted communications between the client and server, you already
have SSH set up, and [the HTTPS alternative](../../ssl.wiki) is
unworkable for some reason.
## 1. Force remote Fossil access through a wrapper script <a id="sshd"></a>
Put something like the following into the `sshd_config` file on the
Fossil repository server:
``` ssh-config
Match Group fossil
X11Forwarding no
AllowTcpForwarding no
AllowAgentForwarding no
ForceCommand /home/fossil/bin/wrapper
```
This file is usually found in `/etc/ssh`, but some OSes put it
elsewhere.
The first line presumes that we will put all users who need to use our
Fossil repositories into the `fossil` group, as we will do
[below](#perms). You could instead say something like:
``` ssh-config
Match User alice,bob,carol,dave
```
You have to list the users allowed to use Fossil in this case because
your system likely has a system administrator that uses SSH for remote
shell access, so you want to *exclude* that user from the list. For the
same reason, you don’t want to put the `ForceCommand` directive outside
a `Match` block of some sort.
You could instead list the exceptions:
``` ssh-config
Match User !evi
```
This would permit only [Evi the System Administrator][evi] to bypass this
mechanism.
[evi]: https://en.wikipedia.org/wiki/Evi_Nemeth
If you have a user that needs both interactive SSH shell access *and*
Fossil access, exclude that user from the `Match` rule and use Fossil’s
normal `ssh://` URL scheme for those cases. This user will bypass the
Fossil RBAC, but they effectively have Setup capability on those
repositories anyway by having full read/write access to the DB files via
the shell.
## 2. Rewrite the sync command with that wrapper <a id="wrapper"></a>
When Fossil syncs over SSH, it attempts to launch a remote Fossil
instance with certain parameters in order to set up the HTTP-based sync
protocol over that SSH tunnel. We need to preserve some of this command
and rewrite other parts to make this work.
Here is a simpler variant of Andy’s original wrapper script:
``` sh
#!/bin/bash
set -- $SSH_ORIGINAL_COMMAND
while [ $# -gt 1 ] ; do shift ; done
export REMOTE_USER="$USER"
ROOT=/home/fossil
exec "$ROOT/bin/fossil" http "$ROOT/museum/$(/bin/basename "$1")"
```
The substantive changes are:
1. Move the command rewriting bits to the start.
2. Be explicit about executable paths. You might extend this idea by
using chroot, BSD jails, Linux containers, etc.
3. Restrict the Fossil repositories to a single flat subdirectory under
the `fossil` user’s home directory. This scheme is easier to secure
than one allowing subdirectories, since you’d need to take care of
`../` and such to prevent a sandbox escape.
4. Don’t take the user name via the SSH command; to this author’s mind,
the user should not get to override their Fossil user name on the
remote server, as that permits impersonation. The identity you
present to the SSH server must be the same identity that the Fossil
repository you’re working with knows you by. Since the users
selected by “`Match`†block above are dedicated to using only Fossil
in this setup, this restriction shouldn’t present a practical problem.
The script’s shebang line assumes `/bin/sh` is POSIX-compliant, but that
is not the case everywhere. If the script fails to run on your system,
try changing this line to point at `bash`, `dash`, `ksh`, or `zsh`. Also
check the absolute paths for local correctness: is `/bin/basename`
installed on your system, for example?
Under this scheme, you clone with a command like:
$ fossil clone ssh://HOST/repo.fossil
This will clone the remote `/home/fossil/museum/repo.fossil` repository
to your local machine under the same name and open it into a “`repo/`â€
subdirectory. Notice that we didn’t have to give the `museum/` part of
the path: it’s implicit per point #3 above.
This presumes your local user name matches the remote user name. Unlike
with `http[s]://` URLs, you don’t have to provide the `USER@` part to
get authenticated access
since this scheme doesn’t permit anonymous cloning. Only
if these two user names are different do you need to add the `USER@` bit to the
URL.
## 3. Set permissions <a id="perms"></a>
This scheme assumes that the users covered by the `Match` rule can read
the wrapper script from where you placed it and execute it, and that
they have read/write access on the directory where the Fossil
repositories are stored.
You can achieve all of this on a Linux box with:
``` shell
sudo adduser fossil
for u in alice bob carol dave ; do
sudo adduser $u
sudo gpasswd -a fossil $u
done
sudo -i -u fossil
chmod 710 .
mkdir -m 750 bin
mkdir -m 770 museum
ln -s /usr/local/bin/fossil bin
```
You then need to copy the Fossil repositories into `~fossil/museum` and
make them readable and writable by group `fossil`. These repositories
presumably already have Fossil users configured, with the necessary
[user capabilities](../../caps/), the point of this article being to
show you how to make Fossil-over-SSH pay attention to those caps.
You must also permit use of `REMOTE_USER` on each shared repository.
Fossil only pays attention to this environment variable in certain
contexts, of which “`fossil http`†is not one. Run this command against
each repo to allow that:
``` shell
echo "INSERT OR REPLACE INTO config VALUES ('remote_user_ok',1,strftime('%s','now'));" |
fossil sql -R museum/repo.fossil
```
Now you can configure SSH authentication for each user. Since Fossil’s
password-saving feature doesn’t work in this case, I suggest setting up
SSH keys via `~USER/.ssh/authorized_keys` since the SSH authentication
occurs on each sync, which Fossil’s default-enabled autosync setting
makes frequent.
Equivalent commands for other OSes should be readily discerned from the
script above.

# Serving via inetd
A Fossil server can be launched on-demand by `inetd` by using the
[`fossil http`](/help/http) command. To do so, add a line like the
following to its configuration file, typically `/etc/inetd.conf`:
80 stream tcp nowait.1000 root /usr/bin/fossil /usr/bin/fossil http /home/fossil/repo.fossil
In this example, you are telling `inetd` that when an incoming
connection appears on TCP port 80 that it should launch the program
`/usr/bin/fossil` with the arguments shown. Obviously you will need to
modify the pathnames for your particular setup. The final argument is
either the name of the fossil repository to be served or a directory
containing multiple repositories.
If you use a non-standard TCP port on systems where the port
specification must be a symbolic name and cannot be numeric, add the
desired name and port to `/etc/services`. For example, if you want your
Fossil server running on TCP port 12345 instead of 80, you will need to
add:
fossil 12345/tcp # fossil server
and use the symbolic name “`fossil`†instead of the numeric TCP port
number (“12345†in the above example) in `inetd.conf`.
Notice that we configured `inetd` to launch Fossil as root. See the
top-level section on “[The Fossil Chroot
Jail](../../chroot.md)†for the consequences of this and
alternatives to it.
You can instead configure `inetd` to bind to a higher-numbered TCP port,
allowing Fossil to be run as a normal user. In that case, Fossil will
not put itself into a chroot jail, because it assumes you have set up
file permissions and such on the server appropriate for that user.
The `inetd` daemon must be enabled for this to work, and it must be
restarted whenever its configuration file changes.
This is a more complicated method than the [standalone HTTP server
method](./none.md), but it has the advantage of only using system
resources when an actual connection is attempted. If no one ever
connects to that port, a Fossil server will not (automatically) run. It
has the disadvantage of requiring "root" access, which may not be
available to you, either due to local IT policy or because of
restrictions at your shared Internet hosting service.
For further details, see the relevant section in your system's
documentation. The FreeBSD Handbook covers `inetd` in [this
chapter](https://www.freebsd.org/doc/en/books/handbook/network-inetd.html).

# Standalone HTTP Server
The easiest way to set up a Fossil server is to use either the
[`server`](/help/server) or [`ui`](/help/ui) command:
* **fossil server** _REPOSITORY_
* **fossil ui** _REPOSITORY_
The _REPOSITORY_ argument is either the name of the repository file or a
directory containing many repositories named “`*.fossil`â€. Both of these
commands start a Fossil server, usually on TCP port 8080, though a
higher numbered port will be used instead if 8080 is already occupied.
You can access these using URLs of the form **http://localhost:8080/**,
or if _REPOSITORY_ is a directory, URLs of the form
**http://localhost:8080/**_repo_**/** where _repo_ is the base name of
the repository file without the “`.fossil`†suffix.
There are several key differences between “`ui`†and “`server`â€:
* “`ui`†always binds the server to the loopback IP address (127.0.0.1)
so that it cannot serve to other machines.
* Anyone who visits this URL is treated as the all-powerful Setup
user, which is why the first difference exists.
* “`ui`†launches a local web browser pointed at this URL.
You can omit the _REPOSITORY_ argument if you run one of the above
commands from within a Fossil checkout directory to serve that
repository:
$ fossil ui # or...
$ fossil server
You can abbreviate Fossil sub-commands as long as they are unambiguous.
“`server`†can currently be as short as “`ser`â€.
You can serve a directory containing multiple `*.fossil` files like so:
$ fossil server --port 9000 --repolist /path/to/repo/dir
There is an [example script](/file/tools/fslsrv) in the Fossil
distribution that wraps `fossil server` to produce more complicated
effects. Feel free to take it, study it, and modify it to suit your
local needs.
See the [online documentation](/help/server) for more information on the
options and arguments you can give to these commands.

# Serving via SCGI
There is an alternative to running Fossil as a [standalone HTTP
server](./none.md), which is to run it in SimpleCGI (a.k.a. SCGI) mode,
which uses the same [`fossil server`](/help/server) command as for HTTP
service. Simply add the `--scgi` command-line option and the stand-alone
server will speak the SCGI protocol rather than raw HTTP.
This can be used with a web server such as [nginx](http://nginx.org)
which does not support [Fossil’s CGI mode](./cgi.md).
A basic nginx configuration to support SCGI with Fossil looks like this:
location /code/ {
include scgi_params;
scgi_param SCRIPT_NAME "/code";
scgi_pass localhost:9000;
}
The `scgi_params` file comes with nginx, and it simply translates nginx
internal variables to `scgi_param` directives to create SCGI environment
variables for the proxied program; in this case, Fossil. Our explicit
`scgi_param` call to define `SCRIPT_NAME` adds one more variable to this
set, which is necessary for this configuration to work properly, because
our repo isn’t at the root of the URL hierarchy. Without it, when Fossil
generates absolute URLs, they’ll be missing the `/code` part at the
start, which will typically cause [404 errors][404].
The final directive simply tells nginx to proxy all calls to URLs under
`/code` down to an SCGI program on TCP port 9000. We can temporarily
set Fossil up as a server on that port like so:
$ fossil server /path/to/repo.fossil --scgi --localhost --port 9000 &
The `--scgi` option switches Fossil into SCGI mode from its default,
which is [stand-alone HTTP server mode](./none.md). All of the other
options discussed in that linked document — such as the ability to serve
a directory full of Fossil repositories rather than just a single
repository — work the same way in SCGI mode.
The `--localhost` option is simply good security: we’re using nginx to
expose Fossil service to the outside world, so there is no good reason
to allow outsiders to contact this Fossil SCGI server directly.
Giving an explicit non-default TCP port number via `--port` is a good
idea to avoid conflicts with use of Fossil’s default TCP service port,
8080, which may conflict with local uses of `fossil ui` and such.
We characterized the SCGI service start command above as “temporaryâ€
because running Fossil in the background like that means it won’t start
back up on a reboot of the server. A simple solution to that is to add
that command to `/etc/rc.local` on systems that have it. However, you
might want to consider setting Fossil up as an OS service instead, so
that you get the benefits of the platform’s service management
framework:
* [Linux (systemd)](../debian/service.md)
* [Windows service](../windows/service.md)
* [macOS (launchd)](../macos/service.md)
* [xinetd](../any/xinetd.md)
* [inetd](../any/inetd.md)
We go into more detail on nginx service setup with Fossil in our
[Debian/Ubuntu specific guide](../debian/nginx.md), which also
gets you TLS service.
Similarly, our [OpenBSD specific guide](../openbsd/fastcgi.md) details how
to setup a Fossil server using httpd and FastCGI on OpenBSD.

# Serving via stunnel
[`stunnel`](https://www.stunnel.org/) is a TLS/SSL proxy for programs
that themselves serve only via HTTP, such as Fossil. (Fossil *can* speak
HTTPS, but only as a client.) `stunnel` decodes the HTTPS data from the
outside world as HTTP before passing it to Fossil, and it encodes the
HTTP replies from Fossil as HTTPS before sending them to the remote host
that made the request.
You can run `stunnel` in one of two modes: socket listener — much like
in our [`inetd` doc](./inetd.md) — and as an HTTP reverse proxy. We’ll
cover both cases here, separately.
## <a id="sa"></a>Socket Activation
The following `stunnel.conf` configuration configures it to run Fossil
in socket listener mode, launching Fossil only when an HTTPS hit comes
in, then shutting it back down as soon as the transaction is complete:
```dosini
[fossil]
accept = 443
TIMEOUTclose = 0
exec = /usr/bin/fossil
execargs = /usr/bin/fossil http /home/fossil/ubercool.fossil --https
cert = /etc/letsencrypt/live/ubercool-project.org/fullchain.pem
key = /etc/letsencrypt/live/ubercool-project.org/privkey.pem
ciphers = ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES128-SHA:DES-CBC3-SHA
options = CIPHER_SERVER_PREFERENCE
```
This configuration shows the TLS certificate generated by the [Let’s
Encrypt](https://letsencrypt.org) [Certbot](https://certbot.eff.org) in
[certonly mode](https://certbot.eff.org/lets-encrypt/debianbuster-other).
There are other ways to get TLS certificates, but this is a popular and
free option.
You will need to adjust the site names and paths in this example. Where
this file goes varies by OS type, so check the man pages on your system
to find out where it should be locally.
See the `stunnel` documentation for further details about this
configuration file.
It is important that the [`fossil http`](/help/http) command in that
configuration include the `--https` option to let Fossil know to use
“`https://`†instead of “`http://`†in generated hyperlinks.
## <a id="proxy"></a>Reverse Proxy
You can instead have Fossil running in the background in [standalone
HTTP server mode](./none.md), bound to a high random TCP port number on
localhost via the `--localhost` and `--port` flags, then configure
`stunnel` to reverse proxy public HTTPS connections down to it via HTTP.
The configuration is the same as the above except that you drop the
`exec` and `execargs` directives and add this instead:
```dosini
connect = 9000
```
That tells `stunnel` to connect to an already-running process listening
on the given TCP port number.
There are a few advantages to this mode:
1. At the cost of some server memory and a tiny bit of idle CPU time,
Fossil remains running so that hits can be served a smidge faster
than in socket listener mode, where the Fossil binary has to be
loaded and re-initialized on each HTTPS hit.
2. The socket listener mode doesn’t work on all platforms that
`stunnel` runs on, particularly [on Windows](../windows/stunnel.md).

# Serving via xinetd
Some operating systems have replaced the old Unix `inetd` daemon with
`xinetd`, which has a similar mission but with a very different
configuration file format.
The typical configuration file is either `/etc/xinetd.conf` or a subfile
in the `/etc/xinetd.d` directory. You need a configuration something
like this for Fossil:
service http
{
port = 80
socket_type = stream
wait = no
user = root
server = /usr/bin/fossil
server_args = http /home/fossil/repos/
}
This example configures Fossil to serve multiple repositories under the
`/home/fossil/repos/` directory.
Beyond this, see the general commentary in our article on [the `inetd`
method](./inetd.md) as they also apply to service via `xinetd`.

# Serving via nginx on Debian and Ubuntu
This document is an extension of [the platform-independent SCGI
instructions][scgii], which may suffice for your purposes if your needs
are simple.
Here, we add more detailed information on nginx itself, plus details
about running it on Debian type OSes. This document was originally
written for and tested on Debian 10 (Buster) and Ubuntu 20.04, which
were common Tier 1 OS offerings for [virtual private servers][vps]
at the time. The same configuration appears to run on Ubuntu 22.04
LTS without change. This material may not work for older OSes. It is
known in particular to not work as given for Debian 9 and older!
We also cover [adding TLS](#tls) to the basic configuration, because several
details depend on the host OS and web stack details. Besides, TLS is
widely considered part of the baseline configuration these days.

## <a id="benefits"></a>Benefits
This scheme is considerably more complicated than the [standalone HTTP
server](../any/none.md) and [CGI options](../any/cgi.md). Even with the
benefit of this guide and pre-built binary packages, it requires quite a
bit of work to set it up. Why should you put up with this complexity?
Because it gives many benefits that are difficult or impossible to get
with the less complicated options:
* **Power** — nginx is one of the most powerful web servers in the
world. The chance that you will run into a web serving wall that you
can’t scale with nginx is very low.
To give you some idea of the sort of thing you can readily
accomplish with nginx, your author runs a single public web server
that provides transparent name-based virtual hosting for four
separate domains:
* <p>One is entirely static, not involving any dynamic content or
Fossil integration at all.</p>
* <p>Another is served almost entirely by Fossil, with a few select
static content exceptions punched past Fossil, which are handled
entirely via nginx.</p>
* <p>The other two domains are aliases for one another — e.g.
`example.com` and `example.net` — with most of the content being
static. This pair of domains has several unrelated Fossil repo
proxies attached to various sections of the URI hierarchy.</p>
By using nginx, I was able to do all of the above with minimal
repetition between the site configurations.
* **Integration** — Because nginx is so popular, it integrates with
many different technologies, and many other systems integrate with it in
turn. This makes it great middleware, sitting between the outer web
world and interior site services like Fossil. It allows Fossil to
participate seamlessly as part of a larger web stack.
* **Availability** — nginx is already in most operating system binary
package repositories, so you don’t need to go out of your way to get it.
## <a id="modes"></a>Fossil Service Modes
Fossil provides four major ways to access a repository it’s serving
remotely, three of which are straightforward to use with nginx:
* **HTTP** — Fossil has [a built-in HTTP server](../any/none.md).
While this method is efficient and it’s
possible to use nginx to proxy access to another HTTP server, we
don’t see any particularly good reason to make nginx reinterpret
Fossil’s own implementation of HTTP when we have a better option.
(But see [below](#http).)
* **SSH** — This method exists primarily to avoid the need for HTTPS,
but we *want* HTTPS. (We’ll get to that [below](#tls).)
There is probably a way to get nginx to proxy Fossil to HTTPS via
SSH, but it would be pointlessly complicated.
* **CGI** — This method is simple but inefficient, because it launches
a separate Fossil instance on every HTTP hit.
Since Fossil is a relatively small self-contained program, and it’s
designed to start up quickly, this method can work well in a
surprisingly large number of cases.
Nevertheless, we will avoid this option in this document because
we’re already buying into a certain amount of complexity here in
order to gain power. There’s no sense in throwing away any of that
hard-won performance on CGI overhead.
* **SCGI** — The [SCGI protocol][scgip] provides the simplicity of CGI
without its performance problems.
SCGI it is, then.
[scgip]: https://en.wikipedia.org/wiki/Simple_Common_Gateway_Interface
## <a id="deps"></a>Installing the Dependencies
The first step is to install some non-default packages we’ll need. SSH into
your server, then say:
$ sudo apt install fossil nginx
You can leave “`fossil`†out of that if you’re building Fossil from
source to get a more up-to-date version than is shipped with the host
OS.
## <a id="scgi"></a>Running Fossil in SCGI Mode
For the following nginx configuration to work, it needs to contact a
background Fossil instance speaking the SCGI protocol. There are
[many ways](../) to set that up, such as [with `systemd`](./service.md)
on mainstream Linux distros. Another way is to [containerize][ctz] your
repository servers, then use the [`fslsrv` wrapper for Podman][fspm] to
generate `systemd` units for use by the front-end proxy.
However you do it, you need to match up the TCP port numbers between it
and those in the nginx configuration below.
[ctz]: ../../containers.md
[fspm]: https://tangentsoft.com/fossil/dir/bin
## <a id="config"></a>Configuration
On Debian and Ubuntu systems the primary user-level configuration file
for nginx is `/etc/nginx/sites-enabled/default`. I recommend that this
file contain only a list of include statements, one for each site that
server hosts:
include local/example.com
include local/foo.net
Those files then each define one domain’s configuration. Here,
`/etc/nginx/local/example.com` contains the configuration for
`*.example.com` and its alias `*.example.net`; and `local/foo.net`
contains the configuration for `*.foo.net`.
The configuration for our `example.com` web site, stored in
`/etc/nginx/sites-enabled/local/example.com` is:
----
server {
server_name .example.com .example.net "";
include local/generic;
include local/code;
access_log /var/log/nginx/example.com-https-access.log;
error_log /var/log/nginx/example.com-https-error.log;
# Bypass Fossil for the static documentation generated from
# our source code by Doxygen, so it merges into the embedded
# doc URL hierarchy at Fossil’s $ROOT/doc without requiring that
# these generated files actually be stored in the repo. This
# also lets us set aggressive caching on these docs, since
# they rarely change.
location /code/doc/html {
root /var/www/example.com/code/doc/html;
location ~* \.(html|ico|css|js|gif|jpg|png)$ {
add_header Vary Accept-Encoding;
access_log off;
expires 7d;
}
}
# Redirect everything under /code to the Fossil instance
location /code {
include local/code;
# Extended caching for URLs that include unique IDs
location ~ "/(artifact|doc|file|raw)/[0-9a-f]{40,64}" {
add_header Cache-Control "public, max-age=31536000, immutable";
include local/code;
access_log off;
}
# Lesser caching for URLs likely to be quasi-static
location ~* \.(css|gif|ico|js|jpg|png)$ {
add_header Vary Accept-Encoding;
include local/code;
access_log off;
expires 7d;
}
}
}
----
As you can see, this is a pure extension of [the basic nginx service
configuration for SCGI][scgii], showing off a few ideas you might want to
try on your own site, such as static asset proxying.
You also need a `local/code` file containing:
include scgi_params;
scgi_pass 127.0.0.1:12345;
scgi_param SCRIPT_NAME "/code";
We separate that out because nginx refuses to inherit certain settings
between nested location blocks, so rather than repeat them, we extract
them to this separate file and include it from both locations where it’s
needed. You see this above where we set far-future expiration dates on
files served by Fossil via URLs that contain hashes that change when the
content changes. It tells your browser that the content of these URLs
can never change without the URL itself changing, which makes your
Fossil-based site considerably faster.
Similarly, the `local/generic` file referenced above helps us reduce unnecessary
repetition among the multiple sites this configuration hosts:
root /var/www/$host;
listen 80;
listen [::]:80;
charset utf-8;
There are some configuration directives that nginx refuses to substitute
variables into, citing performance considerations, so there is a limit
to how much repetition you can squeeze out this way. One such example
are the `access_log` and `error_log` directives, which follow an obvious
pattern from one host to the next. Sadly, you must tolerate some
repetition across `server { }` blocks when setting up multiple domains
on a single server.
The configuration for `foo.net` is similar.
See [the nginx docs](https://nginx.org/en/docs/) for more ideas.
## <a id="http"></a>Proxying HTTP Anyway
[Above](#modes), we argued that proxying SCGI is a better option than
making nginx reinterpret Fossil’s own implementation of HTTP. If you
want Fossil to speak HTTP, just [set Fossil up as a standalone
server](../any/none.md). And if you want nginx to [provide TLS
encryption for Fossil](#tls), proxying HTTP instead of SCGI provides no
benefit.
However, it is still worth showing the proper method of proxying
Fossil’s HTTP server through nginx if only to make reading nginx
documentation on other sites easier:
location /code {
rewrite ^/code(/.*) $1 break;
proxy_pass http://127.0.0.1:12345;
}
The most common thing people get wrong when hand-rolling a configuration
like this is to get the slashes wrong. Fossil is sensitive to this. For
instance, Fossil will not collapse double slashes down to a single
slash, as some other HTTP servers will.
## <a id="large-uv"></a> Allowing Large Unversioned Files
By default, nginx only accepts HTTP messages [up to a
meg](http://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size)
in size. Fossil chunks its sync protocol such that this is not normally
a problem, but when sending [unversioned content][uv], it uses a single
message for the entire file. Therefore, if you will be storing files
larger than this limit as unversioned content, you need to raise the
limit. Within the `location` block:
# Allow large unversioned file uploads, such as PDFs
client_max_body_size 20M;
[uv]: ../../unvers.wiki
## <a id="fail2ban"></a> Integrating `fail2ban`
One of the nice things that falls out of proxying Fossil behind nginx is
that it makes it easier to configure `fail2ban` to recognize attacks on
Fossil and automatically block them. Fossil logs the sorts of errors we
want to detect, but it does so in places like the repository’s admin
log, a SQL table, which `fail2ban` doesn’t know how to query. By putting
Fossil behind an nginx proxy, we convert these failures to log file
form, which `fail2ban` is designed to handle.
First, install `fail2ban`, if you haven’t already:
sudo apt install fail2ban
We’d like `fail2ban` to react to Fossil `/login` failures. The stock
configuration of `fail2ban` only detects a few common sorts of SSH
attacks by default, and its included (but disabled) nginx attack
detectors don’t include one that knows how to detect an attack on
Fossil. We have to teach it by putting the following into
`/etc/fail2ban/filter.d/nginx-fossil-login.conf`:
[Definition]
failregex = ^<HOST> - .*POST .*/login HTTP/..." 401
That teaches `fail2ban` how to recognize the errors logged by Fossil.
Then in `/etc/fail2ban/jail.local`, add this section:
[nginx-fossil-login]
enabled = true
logpath = /var/log/nginx/*-https-access.log
The last line is the key: it tells `fail2ban` where we’ve put all of our
per-repo access logs in the nginx config above.
There’s a [lot more you can do][dof2b], but that gets us out of scope of
this guide.
[dof2b]: https://www.digitalocean.com/community/tutorials/how-to-protect-an-nginx-server-with-fail2ban-on-ubuntu-14-04
## <a id="tls"></a> Adding TLS (HTTPS) Support
One of the [many ways](../../ssl.wiki) to provide TLS-encrypted HTTP
access (a.k.a. HTTPS) to Fossil is to run it behind a web proxy that
supports TLS. Because one such option is nginx, it’s best to delegate
TLS to it if you were already using nginx for some other reason, such as
static content serving, with only part of the site being served by
Fossil.
The simplest way by far to do this is to use [Let’s Encrypt][LE]’s
[Certbot][CB], which can configure nginx for you and keep its
certificates up to date. You need but follow their [nginx on Ubuntu 20
guide][CBU]. We had trouble with this in the past, but either Certbot
has gotten smarter or our nginx configurations have gotten simpler, so
we have removed the manual instructions we used to have here.
You may wish to include something like this from each `server { }`
block in your configuration to enable TLS in a common, secure way:
```
# Tell nginx to accept TLS-encrypted HTTPS on the standard TCP port.
listen 443 ssl;
listen [::]:443 ssl;
# Reference the TLS cert files produced by Certbot.
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
# Load the Let's Encrypt Diffie-Hellman parameters generated for
# this server. Without this, the server is vulnerable to Logjam.
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
# Tighten things down further, per Qualys’ and Certbot’s advice.
ssl_session_cache shared:le_nginx_SSL:1m;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;
ssl_session_timeout 1440m;
# Offer OCSP certificate stapling.
ssl_stapling on;
ssl_stapling_verify on;
# Enable HSTS.
include local/enable-hsts;
```
The [HSTS] step is optional and should be applied only after due
consideration, since it has the potential to lock users out of your
site if you later change your mind on the TLS configuration.
The `local/enable-hsts` file it references is simply:
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
It’s a separate file because nginx requires that headers like this be
applied separately for each `location { }` block. We’ve therefore
factored this out so you can `include` it everywhere you need it.
The [OCSP] step is optional, but recommended.
You may find [Qualys’ SSL Server Test][QSLT] helpful in verifying that
you have set all this up correctly, and that the configuration is
strong. We’ve found their [best practices doc][QSLC] to be helpful. As
of this writing, the above configuration yields an A+ rating when run on
Ubuntu 22.04.01 LTS.

# Serving via systemd on Debian and Ubuntu
[`systemd`][sdhome] is the service management framework in all major
in-support versions of Linux. There are multiple ways to run Fossil
under `systemd`.
[sdhome]: https://www.freedesktop.org/wiki/Software/systemd/
[wpa]: https://en.wikipedia.org/wiki/Systemd#Adoption
## Containerized Service
Two of the methods for running [containerized Fossil][cntdoc] integrate
with `systemd`, potentially obviating the more direct methods below:
* If you take [the Podman method][podman] of running containerized
Fossil, it opens the `podman generate systemd` option for you, as
exemplified in [the `fslsrv` script][fslsrv] used on this author’s
public Fossil-based web site. That script pulls its container images
from [my Docker Hub repo][dhrepo] to avoid the need for my public
Fossil server to have build tools and a copy of the Fossil source
tree. You’re welcome to use my images as-is, or you may use these
tools to bounce custom builds up through a separate container image
repo you manage.
* If you’re willing to give up [a lot of features][nsweak] relative to
Podman, and you’re willing to tolerate a lot more manual
administrivia, [the nspawn method][nspawn] has a lot less overhead,
being a direct feature of `systemd` itself.
Both of these options provide [better security][cntsec] than running
Fossil directly under `systemd`, among [other benefits][cntdoc].

[cntsec]: ../../containers.md#security

[fslsrv]: https://tangentsoft.com/fossil/dir?name=bin
[nspawn]: ../../containers.md#nspawn
[nsweak]: ../../containers.md#nspawn-weaknesses
[podman]: ../../containers.md#podman
## User Service
A fun thing you can easily do with `systemd` that you can’t directly do
with older technologies like `inetd` and `xinetd` is to set a server up
as a “user†service.
You can’t listen on TCP port 80 with this method due to security
restrictions on TCP ports in every OS where `systemd` runs, but you can
create a listener socket on a high-numbered (≥ 1024) TCP port,
suitable for sharing a Fossil repo to a workgroup on a private LAN.
To do this, write the following in
`~/.local/share/systemd/user/fossil.service`:
```dosini
[Unit]
Description=Fossil user server
After=network-online.target
[Service]

Unlike with `inetd` and `xinetd`, we don’t need to tell `systemd` which
user and group to run this service as, because we’ve installed it
under the account we’re logged into, which `systemd` will use as the
service’s owner.
The result is essentially [the standalone server method](../any/none.md)
coupled with an intelligent service manager that will start it
automatically in the background on system boot, perform automatic
service restarts with back-off logic, and more, making this much more
robust than the by-hand launches of `fossil` in the platform-independent
Fossil server instructions. The service will stay up until we
explicitly tell it to shut down.
This scheme couples well with [the generic SCGI instructions][scgi] as
it requires a way to run the underlying repository server in the
background. Given that its service port is then proxied by SCGI, it
follows that it doesn’t need to run as a system service. A user service
works perfectly well for this.
Because we’ve set this up as a user service, the commands you give to
manipulate the service vary somewhat from the sort you’re more likely to
find online:
$ systemctl --user daemon-reload
$ systemctl --user enable fossil
$ systemctl --user start fossil
$ systemctl --user status fossil -l
$ systemctl --user stop fossil
That is, we don’t need to talk to `systemd` with `sudo` privileges, but
we do need to tell it to look at the user configuration rather than the
system-level configuration.
This scheme isolates the permissions needed by the Fossil server, which
reduces the amount of damage it can do if there is ever a
remotely-triggerable security flaw found in Fossil.
On some `systemd` based OSes, user services only run while that user is
logged in interactively. This is common on systems aiming to provide
desktop environments, where this is the behavior you often want. To
allow background services to continue to run after logout, say:
$ sudo loginctl enable-linger $USER
You can paste the command just like that into your terminal, since
`$USER` will expand to your login name.
[scgi]: ../any/scgi.md
### System Service Alternative
There are some common reasons that you’d have good cause to install
Fossil as a system-level service rather than the prior user-level one:
* You’re using [the new `fossil server --cert` feature][sslsrv] to get
TLS service and want it to listen directly on port 443, rather than be
proxied, as one had to do before Fossil got the ability to act as a
TLS server itself. That requires root privileges, so you can’t run
it as a user-level service.
* You’re proxying Fossil with [nginx](./nginx.md) or similar, allowing
it to bind to high-numbered ports, but because it starts as a system
service, you can’t get Fossil into the same dependency chain to
ensure things start up and shut down in the proper order unless it
*also* runs as a system service.
* You want to make use of Fossil’s [chroot jail feature][cjail], which
requires the server to start as root.
There are just a small set of changes required:
1. Install the unit file to one of the persistent system-level unit
file directories. Typically, these are:
/etc/systemd/system
/lib/systemd/system
2. Add `User` and `Group` directives to the `[Service]` section so
Fossil runs as a normal user, preferably one with access only to
the Fossil repo files, rather than running as `root`.
[sslsrv]: ../../ssl-server.md
[cjail]: ../../chroot.md
## Socket Activation
Another useful method to serve a Fossil repo via `systemd` is via a
socket listener, which `systemd` calls “[socket activation][sa],â€
roughly equivalent to [the ancient `inetd` method](../any/inetd.md).
It’s more complicated, but it has some nice properties.
We first need to define the privileged socket listener by writing
`/etc/systemd/system/fossil.socket`:
```dosini
[Unit]
Description=Fossil socket
[Socket]
Accept=yes
ListenStream=80
NoDelay=true
[Install]
WantedBy=sockets.target
```
Note the change of configuration directory from the `~/.local` directory
to the system level. We need to start this socket listener at the root
level because of the low-numbered TCP port restriction we brought up
above.
This configuration says more or less the same thing as the socket part
of an `inetd` entry [exemplified elsewhere in this
documentation](../any/inetd.md).
Next, create the service definition file in that same directory as
`fossil@.service`:
```dosini
[Unit]
Description=Fossil socket server
After=network-online.target
[Service]
WorkingDirectory=/home/fossil/museum
ExecStart=/home/fossil/bin/fossil http repo.fossil
StandardInput=socket
[Install]
WantedBy=multi-user.target
```
Notice that we haven’t told `systemd` which user and group to run Fossil
under. Since this is a system-level service definition, that means it
will run as root, which then causes Fossil to [automatically drop into a
`chroot(2)` jail](../../chroot.md) rooted at the `WorkingDirectory`
we’ve configured above, shortly after each `fossil http` call starts.
The `Restart*` directives we had in the user service configuration above
are unnecessary for this method, since Fossil isn’t supposed to remain
running under it. Each HTTP hit starts one Fossil instance, which
handles that single client’s request and then immediately shuts down.
Next, you need to tell `systemd` to reload its system-level
configuration files and enable the listening socket:
$ sudo systemctl daemon-reload
$ sudo systemctl enable fossil.socket
And now you can manipulate the socket listener:
$ sudo systemctl start fossil.socket
$ sudo systemctl status -l fossil.socket
$ sudo systemctl stop fossil.socket
Notice that we’re working with the *socket*, not the *service*. The fact
that we’ve given them the same base name and marked the service as an
instantiated service with the “`@`†notation allows `systemd` to
automatically start an instance of the service each time a hit comes in
on the socket that `systemd` is monitoring on Fossil’s behalf. To see
this service instantiation at work, visit a long-running Fossil page
(e.g. `/tarball`) and then give a command like this:
$ sudo systemctl --full | grep fossil
This will show information about the `fossil` socket and service
instances, which should show your `/tarball` hit handler, if it’s still
running:
fossil@20-127.0.0.1:80-127.0.0.1:38304.service
You can feed that service instance description to a `systemctl kill`
command to stop that single instance without restarting the whole
`fossil` service, for example.
In all of this, realize that we’re able to manipulate a single socket
listener or single service instance at a time, rather than reload the
whole externally-facing network configuration as with the far more
primitive `inetd` service.

<h2>No Server Required</h2>
<p>Fossil does not require a central server, but <a
href="whyuseaserver.wiki">a server can be useful</a>.</p>
<p>A Fossil server does not require much memory, CPU, or disk space
and can run comfortably on a generic $5/month virtual host
or on a small device like a Raspberry Pi, or it can co-exist
on a host running other services without getting in the way.
<p>This article is a quick-reference guide for setting up your own
Fossil server, with links to more detailed instructions specific to
particular systems, should you want extra help.</p>
<h2 id="prep">Repository Prep</h2>
<p>Prior to serving a Fossil repository to others, consider running <a
href="$ROOT/help?cmd=ui"><tt>fossil ui</tt></a> locally and taking these
minimum recommended preparation steps:</p>
<ol>
<li><p>Fossil creates only one user in a <a
href="$ROOT/help?cmd=new">new repository</a> and gives it the <a
href="../caps/admin-v-setup.md#apsu">all-powerful Setup capability</a>.
The 10-digit random password generated for that user is fairly strong
against remote attack, even without explicit password guess rate
limiting, but because that user has so much power, you may want to
give it a much stronger password under Admin → Users.</a></li>
<li><p>Run the Admin → Security-Audit tool to verify that other
security-related permissions and settings are as you want them.
Consider clicking the “Take it private†link on that page to lock down
the security on that site to a level appropriate to a private
repository, even if you will eventually want some public service. It's
better to start from a secure position and open up service
feature-by-feature as necessary than it is to start from a fully open
position and lock down features one by one to achieve a secure
stance.</p></li>
</ol>
<p>With the repository secured, it is safe to upload a copy of the
repository file to your server and proceed with server setup, below.
Further configuration steps can wait until <a href="#postsetup">after
the server is running</a>.</p>
<h2 id="methods">Activation Methods</h2>
<p>There are basically five ways to run a Fossil server:</p>
<ol>
<li><a href="any/cgi.md">CGI</a>
<li><a href="#slist">Socket listener</a>
<li><a href="any/none.md">Stand-alone HTTP server</a>
<li><a href="any/scgi.md">SCGI</a>
<li><a href="#ssh">SSH</a>
</ol>
<p>All of these methods can serve either a single repository or a
directory hierarchy containing multiple repositories.</p>
<p>You are not restricted to a single server setup. The same Fossil
repository can be served using two or more of the above techniques at
the same time. These methods use clean, well-defined, standard
interfaces (CGI, SCGI, and HTTP) which allow you to easily migrate from
one method to another in response to changes in hosting providers or
administrator preferences.</p>
<h3 id="cgi">CGI</h3>
<p>Most ordinary web servers can <a href="any/cgi.md">run Fossil as a
CGI script</a>. This method is known to work with Apache,
<tt>lighttpd</tt>, and <a
href="any/althttpd.md"><tt>althttpd</tt></a>. The Fossil server
administrator places a <a href="$ROOT/help?cmd=cgi">short CGI script</a> in
the web server's document hierarchy and when a client requests the URL
that corresponds to that script, Fossil runs and generates the
response.</p>
<p>CGI is a good choice for merging Fossil into an existing web site,
particularly on hosts that have CGI set up and working.
The Fossil <a href="../selfhost.wiki">self-hosting repositories</a> are
implemented with CGI underneath <tt>althttpd</tt>.</p>
<h3 id="slist">Socket Listener</h3>
<p>Socket listener daemons such as
<a id="inetd" href="any/inetd.md"><tt>inetd</tt></a>, <a id="xinetd"
href="any/xinetd.md"><tt>xinetd</tt></a>, <a id="stunnel"
href="any/stunnel.md"><tt>stunnel</tt></a>, <a
href="macos/service.md"><tt>launchd</tt></a>, and <a
href="debian/service.md"><tt>systemd</tt></a>
can be configured to invoke the the
<a href="$ROOT/help?cmd=http"><tt>fossil http</tt></a> command to handle
each incoming HTTP request. The "<tt>fossil http</tt>" command reads
the HTTP request off of standard input, computes an appropriate
reply, and writes the reply on standard output. There is a separate
invocation of the "<tt>fossil http</tt>" command for each HTTP request.
The socket listener daemon takes care of relaying content to and from
the client, and (in the case of <a href="any/stunnel.md">stunnel</a>)
handling TLS decryption and encryption.
<h3 id="standalone">Stand-alone HTTP Server</h3>
<p>This is the <a href="any/none.md">easiest method</a>.
A stand-alone server uses the
<a href="$ROOT/help?cmd=server"><tt>fossil server</tt></a> command to run a
process that listens for incoming HTTP requests on a socket and then
dispatches a copy of itself to deal with each incoming request. You can
expose Fossil directly to the clients in this way or you can interpose a
<a href="https://en.wikipedia.org/wiki/Reverse_proxy">reverse proxy</a>
layer between the clients and Fossil.</p>
<h3 id="scgi">SCGI</h3>
<p>The Fossil standalone server can also handle <a href="any/scgi.md">SCGI</a>.
When the <a href="$ROOT/help?cmd=server"><tt>fossil server</tt></a> command is
run with the extra <tt>--scgi</tt> option, it listens for incoming
SCGI requests rather than HTTP requests. This allows Fossil to
respond to requests from web servers <a href="debian/nginx.md">such as
nginx</a> that don't support CGI. SCGI is a simpler protocol to proxy
than HTTP, since the HTTP doesn't have to be re-interpreted in terms of
the proxy's existing HTTP implementation, but it's more complex to set
up because you also have to set up an SCGI-to-HTTP proxy for it. It is
worth taking on this difficulty only when you need to integrate Fossil
into an existing web site already being served by an SCGI-capable web
server.</p>
<h3 id="ssh">SSH</h3>
<p>Fossil supports <tt>ssh://</tt> URLs, but there are <a
href="../caps/#webonly">practical limitations</a> with the default
behavior. You can get the full power of <a href="../caps/">Fossil's RBAC
system</a> over SSH <a href="any/http-over-ssh.md">with a bit of clever
configuration</a>.</p>
<h2 id="matrix">Activation Tutorials</h2>
<p>We've broken the configuration for each method out into a series of
sub-articles. Some of these are generic, while others depend on

# Serving via launchd on macOS
[`launchd`][ldhome] is the default service management framework on macOS
[since the release of Tiger in 2005][wpa]. If you want a Fossil server
to launch in the background on a Mac, it’s the way Apple wants you to do
it. `launchd` is to macOS as `systemd` is to most modern Linux desktop
systems. (Indeed, `systemd` arguably reinvented the perfectly good,
pre-existing `launchd` wheel.)
Unlike in [our `systemd` article](../debian/service.md), we’re not going
to show the per-user method here, because those so-called
[LaunchAgents][la] only start when a user is logged into the GUI, and
they stop when that user logs out. This does not strike us as proper
“server†behavior, so we’ll stick to system-level LaunchDaemons instead.
However, we will still give two different configurations, just as in the
`systemd` article: one for a standalone HTTP server, and one using
socket activation.
For more information on `launchd`, the single best resource we’ve found
is [launchd.info](https://launchd.info). The next best is:
$ man launchd.plist
[la]: http://www.grivet-tools.com/blog/2014/launchdaemons-vs-launchagents/
[ldhome]: https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingLaunchdJobs.html
[wpa]: https://en.wikipedia.org/wiki/Launchd
## Standalone HTTP Server
To configure `launchd` to start Fossil as a standalone HTTP server,
write the following as `com.example.dev.FossilHTTP.plist`:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.example.dev.FossilHTTP</string>
<key>ProgramArguments</key>
<array>
<string>/usr/local/bin/fossil</string>
<string>server</string>
<string>--port</string>
<string>9000</string>
<string>repo.fossil</string>
</array>
<key>WorkingDirectory</key>
<string>/Users/you/museum</string>
<key>KeepAlive</key>
<true/>
<key>RunAtLoad</key>
<true/>
<key>StandardErrorPath</key>
<string>/tmp/fossil-error.log</string>
<key>StandardOutPath</key>
<string>/tmp/fossil-info.log</string>
<key>UserName</key>
<string>you</string>
<key>GroupName</key>
<string>staff</string>
<key>InitGroups</key>
<true/>
</dict>
</plist>
```
In this example, we’re assuming your development organization uses the
domain name “`dev.example.org`â€, that your short macOS login name is
“`you`â€, and that you store your Fossils in “`~/museum`â€. Adjust these
elements of the plist file to suit your local situation.
You might be wondering about the use of `UserName`: isn’t Fossil
supposed to drop privileges and enter [a `chroot(2)`
jail](../../chroot.md) when it’s started as root like this? Why do we
need to give it a user name? Won’t Fossil use the owner of the
repository file to set that? All I can tell you is that in testing here,
if you leave the user and group configuration at the tail end of that
plist file out, Fossil will remain running as root!
Install that file and set it to start with:
$ sudo install -o root -g wheel -m 644 com.example.dev.FossilHTTP.plist \
/Library/LaunchDaemons/
$ sudo launchctl load -w /Library/LaunchDaemons/com.example.dev.FossilHTTP.plist
Because we set the `RunAtLoad` key, this will also launch the daemon.
Stop the daemon with:
$ sudo launchctl unload -w /Library/LaunchDaemons/com.example.dev.FossilHTTP.plist
## Socket Listener
Another useful method to serve a Fossil repo via `launchd` is by setting
up a socket listener:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.example.dev.FossilSocket</string>
<key>ProgramArguments</key>
<array>
<string>/usr/local/bin/fossil</string>
<string>http</string>
<string>repo.fossil</string>
</array>
<key>Sockets</key>
<dict>
<key>Listeners</key>
<dict>
<key>SockServiceName</key>
<string>9001</string>
<key>SockType</key>
<string>stream</string>
<key>SockProtocol</key>
<string>TCP</string>
<key>SockFamily</key>
<string>IPv4</string>
</dict>
</dict>
<key>inetdCompatibility</key>
<dict>
<key>Wait</key>
<false/>
</dict>
<key>WorkingDirectory</key>
<string>/Users/you/museum</string>
<key>UserName</key>
<string>you</string>
<key>GroupName</key>
<string>staff</string>
<key>InitGroups</key>
<true/>
</dict>
</plist>
```
Save it as “`com.example.dev.FossilSocket.plist`†and install and load
it into `launchd` as above.
This version differs in several key ways:
1. We’re calling Fossil as `fossil http` rather than `fossil server` to
make it serve a single request and then shut down immediately.
2. We’ve told `launchd` to listen on our TCP port number instead of
passing it to `fossil`.
3. We’re running the daemon in `inetd` compatibility mode of `launchd`
with “wait†mode off, which tells it to attach the connected socket
to the `fossil` process’s stdio handles.
4. We’ve removed the `Standard*Path` keys because they interfere with
our use of stdio handles for HTTP I/O. You might therefore want to
start with the first method and then switch over to this one only
once you’ve got the daemon launching debugged, since once you tie up
stdio this way, you won’t be able to get logging information from
Fossil via that path. (Fossil does have some internal logging
mechanisms, but you can’t get at them until Fossil is launching!)
5. We’ve removed the `KeepAlive` and `RunAtLoad` keys because those
options aren’t appropriate to this type of service.
6. Because we’re running it via a socket listener instead of as a
standalone HTTP server, the Fossil service only takes system
resources when it’s actually handling an HTTP hit. If your Fossil
server is mostly idle, this method will be a bit more efficient than
the first option.

# Serving via httpd on OpenBSD
[`httpd`][httpd] is the default web server that is included in the base
install on OpenBSD. It's minimal and lightweight but secure and capable,
and provides a clean interface for setting up a Fossil server using
FastCGI.
This article will detail the steps required to setup a TLS-enabled
`httpd` configuration that serves multiple Fossil repositories out of
a single directory within a chroot, and allow `ssh` access to create
new repositories remotely.
**NOTE:** The following instructions assume an OpenBSD 6.7 installation.
[httpd]: https://www.openbsd.org/papers/httpd-asiabsdcon2015.pdf
## <a id="fslinstall"></a>Install Fossil
Use the OpenBSD package manager `pkg_add` to install Fossil, making sure
to select the statically linked binary.
```console
$ doas pkg_add fossil
quirks-3.325 signed on 2020-06-12T06:24:53Z
Ambiguous: choose package for fossil
0: <None>
1: fossil-2.10v0
2: fossil-2.10v0-static
Your choice: 2
fossil-2.10v0-static: ok
```
This installs Fossil into the chroot. To facilitate local use, create a
symbolic link of the fossil executable into `/usr/local/bin`.
```console
$ doas ln -s /var/www/bin/fossil /usr/local/bin/fossil
```
As a privileged user, create the file `/var/www/cgi-bin/scm` with the
following contents to make the CGI script that `httpd` will execute in
response to `fsl.domain.tld` requests; all paths are relative to the
`/var/www` chroot.
```sh
#!/bin/fossil
directory: /htdocs/fsl.domain.tld
notfound: https://domain.tld
repolist
errorlog: /logs/fossil.log
```
The `directory` directive instructs Fossil to serve all repositories
found in `/var/www/htdocs/fsl.domain.tld`, while `errorlog` sets logging
to be saved to `/var/www/logs/fossil.log`; create the repository
directory and log file—making the latter owned by the `www` user, and
the script executable.
```console
$ doas mkdir /var/www/htdocs/fsl.domain.tld
$ doas touch /var/www/logs/fossil.log
$ doas chown www /var/www/logs/fossil.log
$ doas chmod 660 /var/www/logs/fossil.log
$ doas chmod 755 /var/www/cgi-bin/scm
```
## <a id="chroot"></a>Setup chroot
Fossil needs both `/dev/random` and `/dev/null`, which aren't accessible
from within the chroot, so need to be constructed; `/var`, however, is
mounted with the `nodev` option. Rather than removing this default
setting, create a small memory filesystem and then mount it on to
`/var/www/dev` with [`mount_mfs(8)`][mfs] so that the `random` and
`null` device files can be created. In order to avoid necessitating a
startup script to recreate the device files at boot, create a template
of the needed ``/dev`` tree to automatically populate the memory
filesystem.
```console
$ doas mkdir /var/www/dev
$ doas install -d -g daemon /template/dev
$ cd /template/dev
$ doas /dev/MAKEDEV urandom
$ doas mknod -m 666 null c 2 2
$ doas mount_mfs -s 1M -P /template/dev /dev/sd0b /var/www/dev
$ ls -l
total 0
crw-rw-rw- 1 root daemon 2, 2 Jun 20 08:56 null
lrwxr-xr-x 1 root daemon 7 Jun 18 06:30 random@ -> urandom
crw-r--r-- 1 root wheel 45, 0 Jun 18 06:30 urandom
```
[mfs]: https://man.openbsd.org/mount_mfs.8
To make the mountable memory filesystem permanent, open `/etc/fstab` as
a privileged user and add the following line to automate creation of the
filesystem at startup:
```console
swap /var/www/dev mfs rw,-s=1048576,-P=/template/dev 0 0
```
The same user that executes the fossil binary must have writable access
to the repository directory that resides within the chroot; on OpenBSD
this is `www`. In addition, grant repository directory ownership to the
user who will push to, pull from, and create repositories.
```console
$ doas chown -R user:www /var/www/htdocs/fsl.domain.tld
$ doas chmod 770 /var/www/htdocs/fsl.domain.tld
```
## <a id="httpdconfig"></a>Configure httpd
On OpenBSD, [httpd.conf(5)][httpd] is the configuration file for
`httpd`. To setup the server to serve all Fossil repositores within the
directory specified in the CGI script, and automatically redirect
standard HTTP requests to HTTPS—apart from [Let's Encrypt][LE]
challenges issued in response to [acme-client(1)][acme] certificate
requests—create `/etc/httpd.conf` as a privileged user with the
following contents.
[LE]: https://letsencrypt.org
[acme]: https://man.openbsd.org/acme-client.1
[httpd.conf(5)]: https://man.openbsd.org/httpd.conf.5
```apache
server "fsl.domain.tld" {
listen on * port http
root "/htdocs/fsl.domain.tld"
location "/.well-known/acme-challenge/*" {
root "/acme"
request strip 2
}
location * {
block return 301 "https://$HTTP_HOST$REQUEST_URI"
}
location "/*" {
fastcgi { param SCRIPT_FILENAME "/cgi-bin/scm" }
}
}
server "fsl.domain.tld" {
listen on * tls port https
root "/htdocs/fsl.domain.tld"
tls {
certificate "/etc/ssl/domain.tld.fullchain.pem"
key "/etc/ssl/private/domain.tld.key"
}
hsts {
max-age 15768000
preload
subdomains
}
connection max request body 104857600
location "/*" {
fastcgi { param SCRIPT_FILENAME "/cgi-bin/scm" }
}
location "/.well-known/acme-challenge/*" {
root "/acme"
request strip 2
}
}
```
[The default limit][dlim] for HTTP messages in OpenBSD’s `httpd` server
is 1Â MiB. Fossil chunks its sync protocol such that this is not
normally a problem, but when sending [unversioned content][uv], it uses
a single message for the entire file. Therefore, if you will be storing
files larger than this limit as unversioned content, you need to raise
the limit as we’ve done above with the “`connection max request body`â€
setting, raising the limit to 100Â MiB.
[dlim]: https://man.openbsd.org/httpd.conf.5#connection
[uv]: ../../unvers.wiki
**NOTE:** If not already in possession of an HTTPS certificate, comment
out the `https` server block and proceed to securing a free
[Let's Encrypt Certificate](#letsencrypt); otherwise skip to
[Start `httpd`](#starthttpd).
## <a id="letsencrypt"></a>Let's Encrypt Certificate
In order for `httpd` to serve HTTPS, secure a free certificate from
Let's Encrypt using `acme-client`. Before issuing the request, however,
ensure you have a zone record for the subdomain with your registrar or
nameserver. Then open `/etc/acme-client.conf` as a privileged user to
configure the request.
```dosini
authority letsencrypt {
api url "https://acme-v02.api.letsencrypt.org/directory"
account key "/etc/acme/letsencrypt-privkey.pem"
}
authority letsencrypt-staging {
api url "https://acme-staging.api.letsencrypt.org/directory"
account key "/etc/acme/letsencrypt-staging-privkey.pem"
}
domain domain.tld {
alternative names { www.domain.tld fsl.domain.tld }
domain key "/etc/ssl/private/domain.tld.key"
domain certificate "/etc/ssl/domain.tld.crt"
domain full chain certificate "/etc/ssl/domain.tld.fullchain.pem"
sign with letsencrypt
}
```
Start `httpd` with the new configuration file, and issue the certificate
request.
```console
$ doas rcctl start httpd
$ doas acme-client -vv domain.tld
acme-client: /etc/acme/letsencrypt-privkey.pem: account key exists (not creating)
acme-client: /etc/acme/letsencrypt-privkey.pem: loaded RSA account key
acme-client: /etc/ssl/private/domain.tld.key: generated RSA domain key
acme-client: https://acme-v01.api.letsencrypt.org/directory: directories
acme-client: acme-v01.api.letsencrypt.org: DNS: 172.65.32.248
...
N(Q????Z???j?j?>W#????b???? H????eb??T??*? DNosz(???n{L}???D???4[?B] (1174 bytes)
acme-client: /etc/ssl/domain.tld.crt: created
acme-client: /etc/ssl/domain.tld.fullchain.pem: created
```
A successful result will output the public certificate, full chain of
trust, and private key into the `/etc/ssl` directory as specified in
`acme-client.conf`.
```console
$ doas ls -lR /etc/ssl
-r--r--r-- 1 root wheel 2.3K Mar 2 01:31:03 2018 domain.tld.crt
-r--r--r-- 1 root wheel 3.9K Mar 2 01:31:03 2018 domain.tld.fullchain.pem
/etc/ssl/private:
-r-------- 1 root wheel 3.2K Mar 2 01:31:03 2018 domain.tld.key
```
Make sure to reopen `/etc/httpd.conf` to uncomment the second server
block responsible for serving HTTPS requests before proceeding.
## <a id="starthttpd"></a>Start `httpd`
With `httpd` configured to serve Fossil repositories out of
`/var/www/htdocs/fsl.domain.tld`, and the certificates and key in place,
enable and start `slowcgi`—OpenBSD's FastCGI wrapper server that will
execute the above Fossil CGI script—before checking that the syntax of
the `httpd.conf` configuration file is correct, and (re)starting the
server (if still running from requesting a Let's Encrypt certificate).
```console
$ doas rcctl enable slowcgi
$ doas rcctl start slowcgi
slowcgi(ok)
$ doas httpd -vnf /etc/httpd.conf
configuration OK
$ doas rcctl start httpd
httpd(ok)
```
## <a id="clientconfig"></a>Configure Client
To facilitate creating new repositories and pushing them to the server,
add the following function to your `~/.cshrc` or `~/.zprofile` or the
config file for whichever shell you are using on your development box.
```sh
finit() {
fossil init $1.fossil && \
chmod 664 $1.fossil && \
fossil open $1.fossil && \
fossil user password $USER $PASSWD && \
fossil remote-url https://$USER:$PASSWD@fsl.domain.tld/$1 && \
rsync --perms $1.fossil $USER@fsl.domain.tld:/var/www/htdocs/fsl.domain.tld/ >/dev/null && \
chmod 644 $1.fossil && \
fossil ui
}
```
This enables a new repository to be made with `finit repo`, which will
create the fossil repository file `repo.fossil` in the current working
directory; by default, the repository user is set to the environment
variable `$USER`. It then opens the repository and sets the user
password to the `$PASSWD` environment variable (which you can either set
with `export PASSWD 'password'` on the command line or add to a
*secured* shell environment file), and the `remote-url` to
`https://fsl.domain.tld/repo` with the credentials of `$USER` who is
authenticated with `$PASSWD`. Finally, it `rsync`'s the file to the
server before opening the local repository in your browser where you can
adjust settings such as anonymous user access, and set pertinent
repository details. Thereafter, you can add files with `fossil add`, and
commit with `fossil ci -m 'commit message'` where Fossil, by default,
will push to the `remote-url`. It's suggested you read the
[Fossil documentation][documentation]; with a sane and consistent
development model, the system is much more efficient and cohesive than
`git`—so the learning curve is not steep at all.

<title>Serving via rc on OpenBSD</title>
OpenBSD provides [https://man.openbsd.org/rc.subr.8|rc.subr(8)],
a framework for writing [https://man.openbsd.org/rc.8|rc(8)] scripts.
<h2>Creating the daemon</h2>
Create the file /etc/rc.d/fossil with contents like the following.
<pre>
#!/bin/ksh
daemon="/usr/local/bin/fossil" # fossil executable
daemon_user="_fossil" # user to run fossil as
daemon_flags="server /home/_fossil/example --repolist --port 8888" # fossil command
. /etc/rc.d/rc.subr
# pexp="$daemon server .*" # See below.
rc_reload=NO # Unsupported by Fossil; 'rcctl reload fossil' kills the process.
rc_bg=YES # Run in the background, since fossil serve does not daemonize itself
rc_cmd $1
</pre>
<h3>pexp</h3>
You may need to uncomment the "pexp=". rc.subr typically
finds the daemon process based by matching the process name and argument list.
Without the "pexp=" line, rc.subr would look for this exact command:
<pre>
/usr/local/bin/fossil server /home/_fossil/example --repolist --port 8888
</pre>
Depending on the arguments and their order, fossil may rewrite the arguments
for display in the process listing ([https://man.openbsd.org/ps.1|ps(1)]),
so rc.subr may fail to find the process through the default match. The example
above does not get rewritten, but the same commands in a different order can
be rewritten.
For example, when I switch the order of the arguments in "daemon_flags",
<pre>
/usr/local/bin/fossil server --repolist --port 8888 /home/_fossil/example
</pre>
the process command is changed to this.
<pre>
/usr/local/bin/fossil server /home/_fossil/example /home/_fossil/example 8888 /home/_fossil/example
</pre>
The commented "pexp=" line instructs rc.subr to choose the process whose
command and arguments text starts with this:
<pre>
/usr/local/bin/fossil server
</pre>
<h2>Enabling the daemon</h2>
Once you have created /etc/rc.d/fossil, run these commands.
<pre>
rcctl enable fossil # add fossil to pkg_scripts in /etc/rc.conf.local
rcctl start fossil # start the daemon now
</pre>
The daemon should now be running and set to start at boot.
<h2>Multiple daemons</h2>
You may want to serve multiple fossil instances with different options.
For example,
* If different users own different repositories, you may want different users
to serve different repositories.
* You may want to serve different repositories on different ports so you can
control them differently with, for example, HTTP reverse proxies or
[https://man.openbsd.org/pf.4|pf(4)].
To run multiple fossil daemons, create multiple files in /etc/rc.d, and
enable each of them. Here are two approaches for creating
the files in /etc/rc.d: Symbolic links and copies.
<h3>Symbolic links</h3>
Suppose you want to run one fossil daemon as user "user1" on port 8881
and another as user "user2" on port 8882. Create the files with
[https://man.openbsd.org/ln.1|ln(1)], and configure them to run different
fossil commands.
<pre>
cd /etc/rc.d
ln -s fossil fossil1
ln -s fossil fossil2
rcctl enable fossil1 fossil2
rcctl set fossil1 user user1
rcctl set fossil2 user user2
rcctl set fossil1 flags 'server /home/user1/repo1.fossil --port 8881'
rcctl set fossil2 flags 'server /home/user2/repo2.fossil --port 8882'
rcctl start fossil1 fossil2
</pre>
<h3>Copies</h3>
You may want to run fossil daemons that are too different to configure
just with [https://man.openbsd.org/rcctl.8|rcctl(8)].
In particular, you can't change the "pexp" with rcctl.
If you want to run fossil commands that are more different,
you may prefer to create separate files in /etc/rc.d.
Replace "ln -s" above with "cp" to accomplish this.
<pre>
cp /etc/rc.d/fossil /etc/rc.d/fossil-user1
cp /etc/rc.d/fossil /etc/rc.d/fossil-user2
</pre>
You can still use commands like "rcctl set fossil-user1 flags", but you
can also edit the "/etc/rc.d/fossil-user1" file.

<title>Benefits of a Fossil Server</title>
<h2>No Server Required</h2>
Fossil does not require a central server.
Data sharing and synchronization can be entirely peer-to-peer.
Fossil uses
[https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type |
conflict-free replicated data types]
to ensure that (in the limit) all participating peers see the same content.
<h2>But, a Server Can Be Useful</h2>
Fossil does not require a server, but a server can be very useful.
Here are a few reasons to set up a Fossil server for your project:
1. <b>A server works as a complete project website.</b>
Fossil does more than just version control. It also supports
[../tickets.wiki|trouble-tickets],
[../wikitheory.wiki|wiki],
a [../chat.md|developer chat room], and a [../forum.wiki|forum].
The [../embeddeddoc.wiki|embedded documentation]
feature provides a great mechanism for providing project documentation.
The [../unvers.wiki|unversioned files] feature is a convenient way
to host builds and downloads on the project website.
2. <b>A server gives developers a common point of rendezvous for
syncing their work.</b>
It is possible for developers to synchronize peer-to-peer but
that requires the developers coordinate the sync, which in turn
requires that the developers both want to sync at the same moment.
A server alleviates this time dependency by allowing each developer
to sync whenever it is convenient. For example, a developer may
choose to automatically sync
after each commit and before each update. Developers all stay
in sync with each other without having to interrupt each other
constantly to set up a peer-to-peer sync.
3. <b>A server provides project leaders with up-to-date status.</b>
Project coordinators and BDFLs can click on a link or two at the
central Fossil server for a project and quickly tell what is
going on. They can do this from anywhere — even from their phones
— without needing to actually sync to the device they are using.
4. <b>A server provides automatic off-site backups.</b>
A Fossil server is an automatic remote backup for all the work
going into a project. ([../backup.md | Within limits].)
You can even set up multiple servers at
multiple sites with automatic synchronization between them for
added redundancy. Such a setup means that no work is lost due
to a single machine failure.
5. <b>A server consolidates [https://www.sqlite.org/howtocorrupt.html
| SQLite corruption risk mitigation] to a single point.</b>
The concerns in section 1 of that document assume you have direct
access to the central DB files, which isn't the case when the
server is remote and secure against tampering.
Section 2 is about file locking, which concerns disappear when Fossil's
on the other side of an HTTP boundary and your server is set up
properly.
Sections 3.1, 4 thru 6, and 8 apply to all Fossil configurations,
but setting up a server lets you address the risks
in a single place. Once a given commit is
sync'd to the server, you can be reasonably sure any client-side
corruption can be fixed with a fresh clone. Ultimately, this
is an argument for off-machine backups, which returns us to reason
#4 above.
Sections 3.2 and the entirety of section 7 are no concern with
Fossil at all, since it's primarily written by the creator and
primary maintainer of SQLite, so you can be certain Fossil doesn't
actively pursue coding strategies known to risk database corruption.
For another take on this topic, see the article
"[https://sqlite.org/useovernet.html | SQLite Over a Network,
Caveats and Considerations]". Fossil runs in rollback mode by
default per recommendation #3 at the end of that article, and a
Fossil server operates as a network proxy for the underlying
SQLite repository DB per recommendation #2. This <i>may</i> permit
you to safely switch it into WAL mode (<b>fossil rebuild --wal</b>)
depending on the underlying storage used by the server itself.
6. <b>A server allows [../caps/ | Fossil's RBAC system] to work.</b>
The role-based access control (RBAC) system in Fossil only works
when the remote system is on the other side of an HTTP barrier.
([../caps/#webonly | Details].) If you want its benefits, you need
a Fossil server setup of some kind.

# Serving via IIS + CGI
## This Is Not the Method You Are Looking For
Setting up CGI service under IIS is surprisingly complicated compared to
running Fossil as a CGI under most other operating systems. We recommend
that you use the simpler [reverse proxying method](./iis.md) instead
unless there is some compelling reason why that method cannot work for
you, such as its dependence on non-stock IIS extensions. (Keep in mind
that both extensions it requires are by Microsoft, not third parties!)
Once you’ve got this scheme working, it gives the same benefits as those
listed at the top of the linked-to document.
There is a small benefit you get from using CGI over reverse proxying on
other OSes, which is that the Fossil program only runs briefly in order
to serve each HTTP hit. Once the request is done, that Fossil instance
shuts back down, releasing all of its resources. You don’t need to keep
a background Fossil HTTP server running full-time to provide CGI-based
Fossil service.
You lose a lot of that benefit on Windows:
1. It only matters to start with on servers that are highly RAM
constrained. (Roughly ≤ 128 MiB.) Our configuration steps below
assume you’re using the Windows and IIS GUIs, which have RAM
requirements well in excess of this, making Fossil’s resource
requirements a drop in the bucket next to them. On the [Azure
B1s][b1s] virtual machine I used to prepare these instructions, the
Windows Server Manager GUI kept filling the VM’s 1 GiB of RAM
during feature installation and crashing. I had to upgrade the VM’s
RAM to 2 GiB just to get useful work done!
2. Process creation on Windows is [much more expensive][cp] than on the
other OSes Fossil runs on, so the benefits of firing up a Fossil
executable to process each HTTP request are partially swamped by the
overhead of doing so.
Therefore, unless you’re willing to replace all of the GUI configuration
steps below with command line equivalents, or shut the GUI down entirely
after configuring IIS, CGI is a much less compelling option on Windows.
**WARNING:** The following tutorial appears to fail with the current
(2019-08-17) version of Fossil, [apparently][fbug] due to an inability
of Fossil to detect that it’s being run in CGI mode.

## Install IIS with CGI Support
The steps for this are identical to those for the [reverse proxying IIS
setup](./iis.md#install) except that you need to enable CGI in the last
step, since it isn’t installed by default. For Windows Server, the path
is:
The path is similar on the consumer-focused versions of Windows, once
you get to that last step.
## Setup
1. Install the Fossil executable to `c:\inetpub\wwwroot\bin` on the web
server. We can’t use an executable you might already have because IIS
runs under a separate user account, so we need to give that
executable special permissions, and that’s easiest to do under the
IIS tree:
2. In IIS Manager (a.k.a. `INETMGR`) drill down into the Sites folder
in the left-side pane and right-click your web site’s
configuration. (e.g. “Default Web Siteâ€)
3. On that menu say “Add Virtual Directory.†Give it the alias “`cgi`â€
and point it at a suitable directory, such as
“`c:\inetpub\wwwroot\cgi`â€.
4. Double-click the “Handler Mappings†icon, then in the right-side
pane, click “Add Script Map...†Apply the following settings:
The Executable path must point to the path we set up in step 1, not
to some other `fossil.exe` you may have elsewhere on your system.
You will need to change the default “`*.dll`†filter in the Open
dialog to “`*.exe`†in order to see it when browsing via the “`...`â€
button.
5. Create a file called `repo.fslcgi` within the CGI directory you
chose in step 3, with a single line like this:
repository: c:\Users\SOMEONE\museum\repo.fossil
Give the actual path to the repository, of course.
6. Up at the top level of IIS Manager, double-click the “ISAPI and CGI
Restrictions†icon, then click “Add...†in the right-side pane.
Give the script you just created permission to execute:
7. In the right-side pane, click “Restart†to apply this configuration,
then test it by visiting the newly-available URL in a browser:
http://localhost/cgi/repo.fslcgi
For more complicated setups such as “directory†mode, see [the generic
CGI instructions](../any/cgi.md).

# Serving via IIS
## Why Bother?
The first part of the scheme below sets Fossil up as an HTTP server, so
you might be wondering why you wouldn’t just modify that to make it
listen on all network interfaces on TCP port 80, so you can avoid the
need for IIS entirely. For simple use cases, you can indeed do without
IIS, but there are several use cases where adding it is helpful:
1. Proxying Fossil with IIS lets you [add TLS encryption][tls], which
[Fossil does not currently speak](../../ssl.wiki) in its server role.
2. The URL rewriting we do below allows Fossil to be part of a larger
site already being served with IIS.
3. You can have a mixed-mode site, with Fossil acting as a powerful
dynamic content management service and IIS as a fast static content
server. The pure-Fossil alternative requires that you check all of
your static content into Fossil as versioned or unversioned
artifacts.
This article shows how you can get any combination of those benefits by
using IIS as a reverse proxy for `fossil server`.
There are other ways to use IIS to serve Fossil, such as [via
CGI](./cgi.md).
## Background Fossil Service Setup
You will need to have the Fossil HTTP server running in the background,
serving some local repository, bound to localhost on a fixed
high-numbered TCP port. For the purposes of testing, simply start it by
hand in your command shell of choice:
fossil serve --port 9000 --localhost repo.fossil
That command assumes you’ve got `fossil.exe` in your `%PATH%` and you’re
in a directory holding `repo.fossil`. See [the platform-independent
instructions](../any/none.md) for further details.
For a more robust setup, we recommend that you [install Fossil as a
Windows service](./service.md), which will allow Fossil to start at
system boot, before anyone has logged in interactively.
## <a id="install"></a>Install IIS
IIS might not be installed in your system yet, so follow the path
appropriate to your host OS. We’ve tested only the latest Microsoft
OSes as of the time of this writing, but the basic process should be
similar on older OSes.
### Windows Server 2019
1. Start “Server Managerâ€
2. Tell it you want to “Add roles and featuresâ€
3. Select “Role-based or feature-based installationâ€
4. Select your local server
5. In the Server Roles section, enable “Web Server (IIS)â€
### Windows
1. Open Control Panel
2. Go to “Programsâ€
3. Select “Turn Windows features on or off†in the left-side pane
4. In the “Windows Features†dialog, enable “Internet Information
Servicesâ€
The default set of IIS features there will suffice for this tutorial,
but you might want to enable additional features.
## Setting up the Proxy
The stock IIS setup doesn’t have reverse proxying features, but they’re
easily added through extensions. You will need to install the
[Application Request Routing][arr] and [URL Rewrite][ure] extensions. In
my testing here, URL Rewrite showed up immediately after installing it,
but I had to reboot the server to get ARR to show up. (Yay Windows.)
You can install these things through the direct links above, or you can
do it via the Web Platform Installer feature of IIS Manager (a.k.a.
`INETMGR`).
Set these extensions up in IIS Manager like so:
1. Double-click the “Application Request Routing Cache†icon.
2. Right-click in the window that results, and select “Server Proxy
Settings...â€
3. Check the “Enable Proxy†box in the dialog. Click the “Apply†text
in the right-side pane.
4. Return to the top server-level configuration area of IIS Manager and
double-click the “URL Rewrite†icon. Alternately, you might find
“URL Rewrite†in the right-side pane from within the ARR settings.
5. Right click in the window that results, and click “Add Rule(s)...â€
Tell it you want a “Blank rule†under “Inbound rulesâ€.
6. In the dialog that results, create a new rule called “Fossil repo
proxy.†Set the “Pattern†to “`^(.*)$`†and “Rewrite URL†set to
“`http://localhost:9000/{R:1}`â€. That tells it to take everything in
the path part of the URL and send it down to localhost:9000, where
`fossil server` is listening.
7. Click “Apply†in the right-side pane, then get back to the top level
configuration for the server, and click “Restart†in that same pane.
At this point, if you go to `http://localhost/` in your browser, you
should see your Fossil repository’s web interface instead of the default
IIS web site, as before you did all of the above.
This is a very simple configuration. You can do more complicated and
interesting things with this, such as redirecting only `/code` URLs to
Fossil by setting the Pattern in step 6 to “`^/code(.*)$`â€. (You would
also need to pass `--baseurl http://example.com/code` in the `fossil
server` command to make this work properly.) IIS would then directly
serve all other URLs. You could also intermix ASP.NET applications in
the URL scheme in this way.
See the documentation on [URL Rewrite rules][urr] for more ideas.

This problem has two halves: ## No App Startup Without Desktop The easy methods for starting a program in Windows at system start all require an interactive desktop. There is no *easy* way to start an arbitrary program on Windows at boot before anyone has logged in. In Unix terms, Windows has no simple equivalent to [the `/etc/rc.local` file][rcl]. You can partially get around the first problem by setting your `fossil server` call up as one of the user’s interactive startup items. Windows 10 has its own [idiosyncratic way of doing this][si10], and in older systems you have [several alternatives to this][si7]. Regardless of the actual mechanism, these will cause the Fossil standalone HTTP server to start on an *interactive desktop login* only. While you’re sitting at the Windows login screen, the Fossil server is *down*. [rcl]: http://nixdoc.net/man-pages/FreeBSD/man8/rc.local.8.html [si10]: https://www.tenforums.com/tutorials/2944-add-delete-enable-disable-startup-items-windows-10-a.html [si7]: https://www.wikihow.com/Change-Startup-Programs-in-Windows-7 ## No Simple Background Mode Windows also lacks a direct equivalent of the Bourne shell’s “`&`†control operator to run a program in the background, which you can give in Unix’s `rc.local` file, which is just a normal Bourne shell script. By “background,†I mean “not attached to any interactive user’s login session.†When the `rc.local` script exits in Unix, any program it backgrounded *stays running*. There is no simple and direct equivalent to this mechanism in Windows. If you set `fossil server` to run on interactive login, as above, it will shut right back down again when that user logs back out. With Windows 10, it’s especially problematic because you can no longer make the OS put off updates arbitrarily: your Fossil server will go down every time Windows Update decides it needs to reboot your computer, and then Fossil service will *stay* down until someone logs back into that machine interactively. ## Better Solutions Because of these problems, we only recommend setting `fossil server` up on Windows this way when you’re a solo developer or you work in a small office where everyone arrives more or less at the same time each day, and everyone goes home about the same time each day, so that one user can keep the Fossil server up through the working day. If your needs go at all beyond this, you should expect proper “server†behavior, which you can get on Windows by [registering Fossil as a Windows service](./service.md), which solves the interactive startup and shutdown problems above, at a bit of complexity over the Startup Items method. You may also want to consider putting that service behind [an IIS front-end proxy](./iis.md) to add additional web serving features. *[Return to the top-level Fossil server article.](../)* |

You have Administrative access to a Windows 2012r2 or above server. 2. You have PowerShell 5.1 or above installed. ## Place Fossil on Server However you obtained your copy of Fossil, it is recommended that you follow Windows conventions and place it within `\Program Files\FossilSCM`, the proper location for the official 64-bit binary. This way Fossil is at an expected location and you will have minimal issues with Windows interfering in your ability to run Fossil as a service. You will need Administrative rights to place fossil at the recommended location. If you will only be running Fossil as a service, you do not need to add this location to the path, though you may do so if you wish. ## Installing Fossil as a Service Luckily the hard work to use Fossil as a Windows Service has been done by the Fossil team. We simply have to install it with the proper command line options. Fossil on Windows has a command `fossil winsrv` to allow installing Fossil as a service on Windows. This command is only documented on the windows executable of Fossil. You must also run the command as administrator for it to be successful. ### Fossil winsrv Example The simplest form of the command is: ``` fossil winsrv create --repository D:/Path/to/Repo.fossil ``` This will create a windows service named 'Fossil-DSCM' running under the local system account and accessible on port 8080 by default. `fossil winsrv` can also start, stop, and delete the service. For all available options, please execute `fossil help winsrv` on a windows install of Fossil. If you wish to serve a directory of repositories, the `fossil winsrv` command requires a slightly different set of options vs. `fossil server`: ``` fossil winsrv create --repository D:/Path/to/Repos --repolist ``` ### Choice of Directory Considerations When the Fossil server will be used at times that files may be locked during virus scanning, it is prudent to arrange that its directory used for temporary files is exempted from such scanning. Ordinarily, this will be a subdirectory named "fossil" in the temporary directory given by the Windows GetTempPath(...) API, [namely](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-gettemppathw#remarks) the value of the first existing environment variable from `%TMP%`, `%TEMP%`, `%USERPROFILE%`, and `%SystemRoot%`; you can look for their actual values in your system by accessing the `/test_env` webpage. Excluding this subdirectory will avoid certain rare failures where the fossil.exe process is unable to use the directory normally during a scan. ### <a id='PowerShell'></a>Advanced service installation using PowerShell As great as `fossil winsrv` is, it does not have one to one reflection of all of the `fossil server` [options](/help?cmd=server). When you need to use some of the more advanced options, such as `--https`, `--skin`, or `--extroot`, you will need to use PowerShell to configure and install the Windows service. PowerShell provides the [New-Service](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/new-service?view=powershell-5.1) command, which we can use to install and configure Fossil as a service. The below should all be entered as a single line in an Administrative PowerShell console. ```PowerShell New-Service -Name fossil -DisplayName fossil -BinaryPathName '"C:\Program Files\FossilSCM\fossil.exe" server --port 8080 --repolist "D:/Path/to/Repos"' -StartupType Automatic ``` Please note the use of forward slashes in the repolist path passed to Fossil. Windows will accept either back slashes or forward slashes in path names, but Fossil has a preference for forward slashes. The use of `--repolist` will make this a multiple repository server. If you want to serve only a single repository, then leave off the `--repolist` parameter and provide the full path to the proper repository file. Other options are listed in the [fossil server](/help?cmd=server) documentation. The service will be installed by default to use the Local Service account. Since Fossil only needs access to local files, this is fine and causes no issues. The service will not be running once installed. You will need to start it to proceed (the `-StartupType Automatic` parameter to `New-Service` will result in the service auto-starting on boot). This can be done by entering ```PowerShell Start-Service -Name fossil ``` in the PowerShell console. Congratulations, you now have a base http accessible Fossil server running on Windows. ### Removing the Windows Service If you want to remove the Fossil service, execute the following from an Administrative PowerShell or Command Prompt console: ``` sc.exe delete fossil ``` If you have Powershell version 6.0 or later, you can use: ```PowerShell Remove-Service -Name fossil ``` with the same effect. *[Return to the top-level Fossil server article.](../)* |

# Using stunnel with Fossil on Windows
While there are many ways to configure Fossil as a server using various web
servers (Apache, IIS, nginx, etc.), this document will focus on setting up a
minimal Fossil server using only Fossil's native [server
capabilities](../any/none.md) and [stunnel](https://www.stunnel.org/)
to provide a TLS proxy. It is recommended for public repositories to go to the
extra step of configuring stunnel to provide a proper HTTPS setup.
## Assumptions
1. You have Administrative access to a Windows 2012r2 or above server.
2. You have PowerShell 5.1 or above installed.
3. You have acquired a certificate either from a Public CA or an Internal CA.
## Configure Fossil Service for https
Due to the need for the `--https` option for successfully using Fossil with
stunnel, we will use [Advanced service installation using PowerShell](./service.md#PowerShell).
We will need to change the command to install the Fossil Service to configure
it properly for use with stunnel as an https proxy. Run the following:
```PowerShell
New-Service -Name fossil-secure -DisplayName fossil-secure -BinaryPathName '"C:\Program Files\FossilSCM\fossil.exe" server --localhost --port 9000 --https --repolist "D:/Path/to/Repos"' -StartupType Automatic
```
The use of `--localhost` means Fossil will only listen for traffic on the local
host on the designated port - 9000 in this case - and will not respond to
network traffic. Using `--https` will tell Fossil to generate HTTPS URLs rather
than HTTP ones.
`New-Service` does not automatically start a service on install, so you will
need to enter the following to avoid rebooting the server:
```PowerShell
Start-Service -Name fossil-secure
```
To remove the service, run the following in a Powershell or cmd console:
```
sc.exe delete fossil
```
or (in a Powershell console)
```PowerShell
Remove-Service -Name fossil
```
if your version of Powershell is 6.0 or above.
## Install stunnel 5.55
Download stunnel from the [downloads](https://www.stunnel.org/downloads.html)
page. Select the latest stunnel windows package (at the time of writing this is
`stunnel-5.55-win64-installer.exe`). Execute the installer and make sure you
install openSSL tools when you install stunnel. You will need this to convert
your certificate from PFX to PEM format.
Even though the installer says it is for win64, it installs stunnel by default
to `\Program Files (x86)\stunnel`.
## Get your certificate ready for Stunnel
Whether you use a Public Certificate Authority or Internal Certificate
Authority, the next step is exporting the certificate from Windows into a format
useable by Stunnel.
### Export Certificate from Windows
If your certificate is installed via Windows Certificate Management, you will
need to export the certificate into a usable format. You can do this either
using the Windows Certificate Management Console, or PowerShell.
#### Certificate Management Console
Start `mmc.exe` as an Administrator. Select 'File>Add/Remove Snapin', select
'Certificates' from the list, and click 'Add'. Select 'Computer Account',
'Next', 'Local Computer', and then 'Finish'. In the Console Root, expand
'Certificates', then 'Personal', and select 'Certificates'. In the middle pane
find and select your certificate. Right click the certificate and select
'All Tasks>Export'. You want to export as PFX the Private Key, include all
certificates in the certification path, and use a password only to secure the
file. Enter a path and file name to a working directory and complete the
export.
Continue with [Convert Certificate from PFX to PEM](#convert).
#### PowerShell
If you know the Friendly
Name of the Certificate this is relatively easy. Since you need to export
the private key as well, you must run the following from an Administrative
PowerShell console.
```PowerShell
$passwd = ConvertTo-SecureString -string "yourpassword" -Force -AsPlainText
Get-ChildItem Cert:\LocalMachine\My | Where{$_.FriendlyName -eq "FriendlyName"} |
Export-PfxCertificate -FilePath fossil-scm.pfx -Password $passwd
```
You will now have your certificate stored as a PFX file.
<a id="convert"></a>
### Convert Certificate from PFX to PEM
For this step you will need the openssl tools that were installed with stunnel.
```PowerShell
# Add stunnel\bin directory to path for this session.
$env:PATH += ";${env:ProgramFiles(x86)}\stunnel\bin"
# Export Private Key
openssl.exe pkcs12 -in fossil-scm.pfx -out fossil-scm.key -nocerts -nodes
# Export the Certificate
openssl.exe pkcs12 -in fossil-scm.pfx -out fossil-scm.pem -nokeys
```
Now move `fossil-scm.key` and `fossil-scm.pem` to your stunnel config directory
(by default this should be located at `\Program Files (x86)\stunne\config`).
## stunnel Configuration
Use the reverse proxy configuration given in the generic [Serving via
stunnel document](../any/stunnel.md#proxy). On Windows, the
`stunnel.conf` file is located at `\Program Files (x86)\stunnel\config`.
You will need to modify it to point at the PEM and key files generated
above.
After completing the above configuration restart the stunnel service in Windows
with the following:
```PowerShell
Restart-Service -Name stunnel
```
## Open up port 443 in the Windows Firewall
The following instructions are for the [Windows Advanced
Firewall](https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-firewall/windows-firewall-with-advanced-security).
If you are using a different Firewall, please consult your Firewall
documentation for how to open port 443 for inbound traffic.
The following command should be entered all on one line.
```PowerShell
New-NetFirewallRule -DisplayName "Allow Fossil Inbound" -Description "Allow Fossil inbound on port 443 using Stunnel as TLS Proxy."
-Direction Inbound -Protocol TCP -LocalPort 443 -Action Allow -Program "C:\Program Files (x86)\Stunnel\bin\stunnel.exe"
```
You should now be able to access your new Fossil Server via HTTPS.

<title>CGI Server Extensions</title>
<h2>1.0 Introduction</h2>
If you have a [./server/|Fossil server] for your project,
you can add [./aboutcgi.wiki|CGI]
extensions to that server. These extensions work like
any other CGI program, except that they also have access to the Fossil
login information and can (optionally) leverage the "[./customskin.md|skins]"
of Fossil so that they appear to be more tightly integrated into the project.
An example of where this is useful is the
[https://sqlite.org/src/ext/checklist|checklist application] on
the [https://sqlite.org/|SQLite] project. The checklist
helps the SQLite developers track which release tests have passed,
or failed, or are still to be done. The checklist program began as a
stand-alone CGI which kept its own private user database and implemented
its own permissions and login system and provided its own CSS. By
converting checklist into a Fossil extension, the same login that works
for the [https://sqlite.org/src|main SQLite source repository] also works
for the checklist. Permission to change elements of the checklist
is tied on permission to check-in to the main source repository. And
the standard Fossil header menu and footer appear on each page of
the checklist.
<h2>2.0 How It Works</h2>
CGI Extensions are disabled by default.
An administrator activates the CGI extension mechanism by specifying
an "Extension Root Directory" or "extroot" as part of the
[./server/index.html|server setup].
If the Fossil server is itself run as
[./server/any/cgi.md|CGI], then add a line to the
[./cgi.wiki#extroot|CGI script file] that says:
<pre>
extroot: <i>DIRECTORY</i>
</pre>
Or, if the Fossil server is being run using the
"[./server/any/none.md|fossil server]" or
"[./server/any/none.md|fossil ui]" or
"[./server/any/inetd.md|fossil http]" commands, then add an extra
"--extroot <i>DIRECTORY</i>" option to that command.
The <i>DIRECTORY</i> is the DOCUMENT_ROOT for the CGI.
Files in the DOCUMENT_ROOT are accessed via URLs like this:
<pre>
https://example-project.org/ext/<i>FILENAME</i>
</pre>
In other words, access files in DOCUMENT_ROOT by appending the filename
relative to DOCUMENT_ROOT to the [/help?cmd=/ext|/ext]
page of the Fossil server.
Files that are readable but not executable are returned as static
content. Files that are executable are run as CGI.
<h3>2.1 Example #1</h3>
The source code repository for SQLite is a Fossil server that is run
as CGI. The URL for the source code repository is [https://sqlite.org/src].
The CGI script looks like this:
<verbatim>
#!/usr/bin/fossil
repository: /fossil/sqlite.fossil
errorlog: /logs/errors.txt
extroot: /sqlite-src-ext
</verbatim>
The "extroot: /sqlite-src-ext" line tells Fossil that it should look for
extension CGIs in the /sqlite-src-ext directory. (All of this is happening
inside of a chroot jail, so putting the document root in a top-level
directory is a reasonable thing to do.)
When a URL like "https://sqlite.org/src/ext/checklist" is received by the
main webserver, it figures out that the /src part refers to the main
Fossil CGI script and so it runs that script. Fossil gets the remainder
of the URL to work with: "/ext/checklist". Fossil extracts the "/ext"
prefix and uses that to determine that this a CGI extension request.
Then it takes the leftover "/checklist" part and appends it to the
"extroot" to get the filename "/sqlite-src-ext/checklist". Fossil finds
that file to be executable, so it runs it as CGI and returns the result.
The /sqlite-src-ext/checklist file is a
[https://wapp.tcl.tk|Wapp program]. The current source code to the
this program can be seen at
[https://www.sqlite.org/src/ext/checklist/3070700/self] and
recent historical versions are available at
[https://sqlite.org/docsrc/finfo/misc/checklist.tcl] with
older legacy at [https://sqlite.org/checklistapp/timeline?n1=all]
There is a cascade of CGIs happening here. The web server that receives
the initial HTTP request runs Fossil as a CGI based on the
"https://sqlite.org/src" portion of the URL. The Fossil instance then
runs the checklist sub-CGI based on the "/ext/checklists" suffix. The
output of the sub-CGI is read by Fossil and then relayed on to the
main web server which in turn relays the result back to the original client.
<h3>2.2 Example #2</h3>
The [https://fossil-scm.org/home|Fossil self-hosting repository] is also
a CGI that looks like this:
<verbatim>
#!/usr/bin/fossil
repository: /fossil/fossil.fossil
errorlog: /logs/errors.txt
extroot: /fossil-extroot
</verbatim>
The extroot for this Fossil server is /fossil-extroot and in that directory
is an executable file named "fileup1" - another [https://wapp.tcl.tk|Wapp]
script. (The extension mechanism is not required to use Wapp. You can use
any kind of program you like. But the creator of SQLite and Fossil is fond
of [https://www.tcl.tk|Tcl/Tk] and so he tends to gravitate toward Tcl-based
technologies like Wapp.) The fileup1 script is a demo program that lets
the user upload a file using a form, and then displays that file in the reply.
There is a link on the page that causes the fileup1 script to return a copy
of its own source-code, so you can see how it works.
<h2 id="cgi-inputs">3.0 CGI Inputs</h2>
The /ext extension mechanism is an ordinary CGI interface. Parameters
are passed to the CGI program using environment variables. The following
standard CGI environment variables are supported:
* AUTH_TYPE
* AUTH_CONTENT
* CONTENT_LENGTH
* CONTENT_TYPE
* DOCUMENT_ROOT
* GATEWAY_INTERFACE
* HTTPS
* HTTP_ACCEPT
* HTTP_ACCEPT_ENCODING
* HTTP_COOKIE
* HTTP_HOST
* HTTP_IF_MODIFIED_SINCE
* HTTP_IF_NONE_MATCH
* HTTP_REFERER
* HTTP_USER_AGENT
* PATH_INFO
* QUERY_STRING
* REMOTE_ADDR
* REMOTE_USER
* REQUEST_METHOD
* REQUEST_SCHEME
* REQUEST_URI
* SCRIPT_DIRECTORY
* SCRIPT_FILENAME
* SCRIPT_NAME
* SERVER_NAME
* SERVER_PORT
* SERVER_PROTOCOL
* SERVER_SOFTWARE
Do a web search for
"[https://duckduckgo.com/?q=cgi+environment_variables|cgi environment variables]"
to find more detail about what each of the above variables mean and how
they are used.
Live listings of the values of some or all of these environment variables
can be found at links like these:
* [https://fossil-scm.org/home/test_env]
* [https://sqlite.org/src/ext/checklist/top/env]
In addition to the standard CGI environment variables listed above,
Fossil adds the following:
* FOSSIL_CAPABILITIES
* FOSSIL_NONCE
* FOSSIL_REPOSITORY
* FOSSIL_URI
* FOSSIL_USER
The FOSSIL_USER string is the name of the logged-in user. This variable
is missing or is an empty string if the user is not logged in. The
FOSSIL_CAPABILITIES string is a list of
[./caps/ref.html|Fossil capabilities] that
indicate what permissions the user has on the Fossil repository.
The FOSSIL_REPOSITORY environment variable gives the filename of the
Fossil repository that is running. The FOSSIL_URI variable shows the
prefix of the REQUEST_URI that is the Fossil CGI script, or is an
empty string if Fossil is being run by some method other than CGI.
The [https://sqlite.org/src/ext/checklist|checklist application] uses the
FOSSIL_USER environment variable to determine the name of the user and
the FOSSIL_CAPABILITIES variable to determine if the user is allowed to
mark off changes to the checklist. Only users with check-in permission
to the Fossil repository are allowed to mark off checklist items. That
means that the FOSSIL_CAPABILITIES string must contain the letter "i".
Search for "FOSSIL_CAPABILITIES" in the
[https://sqlite.org/src/ext/checklist/top/self|source listing] to see how
this happens.
If the CGI output is one of the forms for which Fossil inserts its own
header and footer, then the inserted header will include a
Content Security Policy (CSP) restriction on the use of javascript within
the webpage. Any <script>...</script> elements within the
CGI output must include a nonce or else they will be suppressed by the
web browser. The FOSSIL_NONCE variable contains the value of that nonce.
So, in other words, to get javascript to work, it must be enclosed in:
<verbatim>
<script nonce='$FOSSIL_NONCE'>...</script>
</verbatim>
Except, of course, the $FOSSIL_NONCE is replaced by the value of the
FOSSIL_NONCE environment variable.
<h3>3.1 Input Content</h3>
If the HTTP request includes content (for example if this is a POST request)
then the CONTENT_LENGTH value will be positive and the data for the content
will be readable on standard input.
<h2>4.0 CGI Outputs</h2>
CGI programs construct a reply by writing to standard output. The first
few lines of output are parameters intended for the web server that invoked
the CGI. These are followed by a blank line and then the content.
Typical parameter output looks like this:
<verbatim>
Status: 200 OK
Content-Type: text/html
</verbatim>
CGI programs can return any content type they want - they are not restricted
to text replies. It is OK for a CGI program to return (for example)
image/png.
The fields of the CGI response header can be any valid HTTP header fields.
Those that Fossil does not understand are simply relayed back to up the
line to the requester.
Fossil takes special action with some content types. If the Content-Type
is "text/x-fossil-wiki" or "text/x-markdown" then Fossil
converts the content from [/wiki_rules|Fossil-Wiki] or
[/md_rules|Markdown] into HTML, adding its
own header and footer text according to the repository skin. Content
of type "text/html" is normally passed straight through
unchanged. However, if the text/html content is of the form:
<verbatim>
<div class='fossil-doc' data-title='DOCUMENT TITLE'>
... HTML content there ...
</div>
</verbatim>
In other words, if the outer-most markup of the HTML is a <div>
element with a single class of "fossil-doc",
then Fossil will adds its own header and footer to the HTML. The
page title contained in the added header will be extracted from the
"data-title" attribute.
Except for the three cases noted above, Fossil makes no changes or
additions to the CGI-generated content. Fossil just passes the verbatim
content back up the stack towards the requester.
<h3>4.1 <tt>GATEWAY_INTERFACE</tt> and Recursive Calls to fossil</h3>
Like many CGI-aware applications, if fossil sees the environment
variable <tt>GATEWAY_INTERFACE</tt> when it starts up, it assumes it
is running in a CGI environment and behaves differently than when it
is run in a non-CGI interactive session. If you intend to run fossil
itself from within an extension CGI script, e.g. to run a query
against the repository or simply fetch the fossil binary version, make
sure to <em>unset</em> the <tt>GATEWAY_INTERFACE</tt> environment
variable before doing so, otherwise the invocation will behave as if
it's being run in CGI mode.
<h2>5.0 Filename Restrictions</h2>
For security reasons, Fossil places restrictions on the names of files
in the extroot directory that can participate in the extension CGI
mechanism:
1. Filenames must consist of only ASCII alphanumeric characters,
".", "_", and "-", and of course "/" as the file separator.
Files with names that includes spaces or
other punctuation or special characters are ignored.
2. No element of the pathname can begin with "." or "-". Files or
directories whose names begin with "." or "-" are ignored.
If a CGI program requires separate data files, it is safe to put those
files in the same directory as the CGI program itself as long as the names
of the data files contain special characters that cause them to be ignored
by Fossil.
<h2>6.0 Access Permissions</h2>
CGI extension files and programs are accessible to everyone.
When CGI extensions have been enabled (using either "extroot:" in the
CGI file or the --extroot option for other server methods) all files
in the extension root directory hierarchy, except special filenames
identified previously, are accessible to all users. Users do not
have to have "Read" privilege, or any other privilege, in order to
access the extensions.
This is by design. The CGI extension mechanism is intended to operate
in the same way as a traditional web-server.
CGI programs that want to restrict access
can examine the FOSSIL_CAPABILITIES and/or FOSSIL_USER environment variables.
In other words, access control is the responsibility of the individual
extension programs.
<h2>7.0 Trouble-Shooting Hints</h2>
Remember that the /ext will return any file in the extroot directory
hierarchy as static content if the file is readable but not executable.
When initially setting up the /ext mechanism, it is sometimes helpful
to verify that you are able to receive static content prior to starting
work on your CGIs. Also remember that CGIs must be
executable files.
Fossil likes to run inside a chroot jail, and will automatically put
itself inside a chroot jail if it can. The sub-CGI program will also
run inside this same chroot jail. Make sure all embedded pathnames
have been adjusted accordingly and that all resources needed by the
CGI program are available within the chroot jail.
If anything goes wrong while trying to process an /ext page, Fossil
returns a 404 Not Found error with no details. However, if the requester
is logged in as a user that has <b>[./caps/ref.html#D | Debug]</b> capability
then additional diagnostic information may be included in the output.
If the /ext page has a "fossil-ext-debug=1" query parameter and if
the requester is logged in as a user with Debug privilege, then the
CGI output is returned verbatim, as text/plain and with the original
header intact. This is useful for diagnosing problems with the
CGI script.

These are <tt>clean-glob</tt>, <tt>binary-glob</tt>, <tt>crlf-glob</tt> (and its alias <tt>crnl-glob</tt>), <tt>empty-dirs</tt>, <tt>encoding-glob</tt>, <tt>ignore-glob</tt>, <tt>keep-glob</tt>, <tt>manifest</tt>, and <tt>mimetypes</tt>. The most important is <tt>ignore-glob</tt> which specifies which files should be ignored when looking for unmanaged files with the <tt>extras</tt> command.

As well as being able to be set using the <tt>settings</tt> command or the web interface, you can create versioned files in the <tt>.fossil-settings</tt> subdirectory of the check-out root, named with the setting name. Each file holds the value of a setting, and these files are checked in, committed, merged, and so on, as with any other file. Where a setting is a list of values, such as <tt>ignore-glob</tt>, you can use a newline as a separator as well as a comma. For example, to set the list of ignored files, create a <tt>.fossil-settings/ignore-glob</tt> file where each line contains a glob for ignored files. If you set the value of a setting using the <tt>settings</tt> command as well as a versioned file, the versioned setting will take precedence. A warning will be displayed. |

<title>Deleting Content From Fossil</title>
<h2>Good Reasons for Removing Content from a Fossil Repository</h2>
Fossil is designed to keep all historical content forever. Fossil
purposely makes it difficult for users to delete content. Old content
is part of the project's <i>*ahem*</i> fossil record and should be
maintained indefinitely to maintain an accurate history of the project.
Nevertheless, there may occasionally arise legitimate reasons for
deleting content. Such reasons include:
* Spammers inserted inappropriate content into a wiki page, forum post,
or ticket. Fossil lets you easily hide or amend such content, but
since it is not a legitimate part of the project's history, there
is no value in keeping it, so it is best removed permanently.
* A file that contains trade secrets or that is under someone else's
copyright was accidentally committed and needs to be backed out.
* A malformed control artifact was inserted and is disrupting the
operation of Fossil.
* A legitimate legal request was received requiring content to
be removed. This would most likely be related to the accidental
intellectual property error or spam cases listed above. Some countries
recognise software patents, and so allow legal claims targetting code
commits. Some countries can require publicly-available encryption
software to be taken down if it is committed to the DAG without
the correct government authorisation.
<h2>Alternatives</h2>
All of these are rare cases: Fossil is [./antibot.wiki | designed to
foil spammers up front], legally problematic check-ins should range from
rare to nonexistent, and you have to go way out of your way to force
Fossil to insert bad control artifacts. Therefore, before we get to
methods of permanently deleting content from a Fossil repo, let's give
some alternatives that usually suffice, which don't damage the project's
fossil record:
* When a forum post or wiki article is "deleted," what actually
happens is that a new empty version is added to the Fossil repository.
The web interface interprets this
as "deleted," but the prior version remains available if you go
digging for it.
* When you close a ticket, it's marked in a way that causes it
to not show up in the normal ticket reports. You usually want to
give it a Resolution such as "Rejected" when this happens, plus
possibly a comment explaining why you're closing it. This is all new
information added to the ticket, not deletion.
* When you <tt>fossil rm</tt> a file, a new manifest is
checked into the repository with the same file list as for the prior
version minus the "removed" file. The file is still present in the
repository; it just isn't part of that version forward on that
branch.
* If you make a bad check-in, you can shunt it off to the side
by amending it to put it on a different branch, then continuing
development on the prior branch:
<br><br>
<code>$ fossil amend abcd1234 --branch BOGUS --hide<br>
$ fossil up trunk</code>
<br><br>
The first command moves check-in ID <tt>abcd1234</tt> (and any
subsequent check-ins on that branch!) to a branch called
<tt>BOGUS</tt>, then hides it so it doesn't show up on the
timeline. You can call this branch anything you like, and you can
re-use the same name as many times as you like. No content is
actually deleted: it's just shunted off to the side and hidden away.
You might find it easier to do this from the Fossil web UI in
the "edit" function for a check-in.
<br><br>
The second command returns to the last good check-in on that branch
so you can continue work from that point.
* When the check-in you want to remove is followed by good
check-ins on the same branch, you can't use the previous method,
because it will move the good check-ins, too. The solution is:
<br><br>
<tt>$ fossil merge --backout abcd1234</tt>
<br><br>
That creates a diff in the check-out directory that backs out the
bad check-in <tt>abcd1234</tt>. You then fix up any merge conflicts,
build, test, etc., then check the reverting change into the
repository. Again, nothing is actually deleted; you're just adding
more information to the repository which corrects a prior
check-in.
<h2>Exception: Non-versioned Content</h2>
It is normal and expected to delete data which is not versioned, such as
usernames and passwords in the user table. The [/help/scrub|fossil scrub]
command will remove all sensitive non-versioned data from a repository.
The scrub command will remove user 'bertina', along with their password,
any supplied IP address, any concealed email address etc. However, in the
DAG, commits by 'bertina' will continue to be visible unchanged even though
there is no longer any such user in Fossil.
<h2>Shunning</h2>
Fossil provides a mechanism called "shunning" for removing content from
a repository.
Every Fossil repository maintains a list of the hash names of
"shunned" artifacts.
Fossil will refuse to push or pull any shunned artifact.
Furthermore, all shunned artifacts (but not the shunning list
itself) are removed from the
repository whenever the repository is reconstructed using the
"rebuild" command.
<h3>Shunning lists are local state</h3>
The shunning list is part of the local state of a Fossil repository.
In other words, shunning does not propagate to a remote repository
using the normal "sync" mechanism. An artifact can be
shunned from one repository but be allowed to exist in another. The fact that
the shunning list does not propagate is a security feature. If the
shunning list propagated then a malicious user (or
a bug in the fossil code) might introduce a shun record that would
propagate through all repositories in a network and permanently
destroy vital information. By refusing to propagate the shunning list,
Fossil ensures that no remote user will ever be able to remove
information from your personal repositories without your permission.
The shunning list does not propagate to a remote repository
by the normal "sync" mechanism,
but it is still possible to copy shuns from one repository to another
using the "configuration" command:
<b>fossil configuration pull shun</b> <i>remote-url</i><br>
<b>fossil configuration push shun</b> <i>remote-url</i>
The two commands above will pull or push shunning lists from or to
the <i>remote-url</i> indicated and merge the lists on the receiving
end. "Admin" privilege on the remote server is required in order to
push a shun list. In contrast, the shunning list will be automatically
received by default as part of a normal client "pull" operation unless
disabled by the "<tt>auto-shun</tt>" setting.
Note that the shunning list remains in the repository even after the
shunned artifact has been removed. This is to prevent the artifact
from being reintroduced into the repository the next time it syncs with
another repository that has not shunned the artifact.
<h3>Managing the shunning list</h3>
The complete shunning list for a repository can be viewed by a user
with "admin" privilege on the "/shun" URL of the web interface to Fossil.
That URL is accessible under the "Admin" button on the default menu
bar. Items can be added to or removed from the shunning list. "Sync"
operations are inhibited as soon as the artifact is added to the
shunning list, but the content of the artifact is not actually removed
from the repository until the next time the repository is rebuilt.
When viewing individual artifacts with the web interface, "admin"
users will usually see a "Shun" option in the submenu that will take
them directly to the shunning page and enable that artifact to be
shunned with a single additional mouse click.

# SSL/TLS Server Mode
## History
Fossil has supported [client-side SSL/TLS][0] since [2010][1]. This means
that commands like "[fossil sync](/help?cmd=sync)" could use SSL/TLS when
contacting a server. But on the server side, commands like
"[fossil server](/help?cmd=server)" operated in clear-text only. To implement
an encrypted server, you had to put Fossil behind a web server or reverse
proxy that handled the SSL/TLS decryption/encryption and passed cleartext
down to Fossil.
[0]: ./ssl.wiki
[1]: /timeline?c=b05cb4a0e15d0712&y=ci&n=13
Beginning in [late December 2021](/timeline?c=f6263bb64195b07f&y=a&n=13),
this has been fixed. Commands like
* "[fossil server](/help?cmd=server)"
* "[fossil ui](/help?cmd=ui)", and
* "[fossil http](/help?cmd=http)"
now all handle server-mode SSL/TLS encryption natively. It is now possible
to run a secure Fossil server without having to put Fossil behind an encrypting
web server or reverse proxy. Hence, it is now possible to stand up a complete
Fossil project website on an inexpensive VPS with no added software other than
Fossil itself and something like [certbot](https://certbot.eff.org) for
obtaining a CA-signed certificate.
## Usage
To put any of the Fossil server commands into SSL/TLS mode, simply
add the "--cert" command-line option.
fossil ui --cert unsafe-builtin
The --cert option is what tells Fossil to use TLS encryption.
Normally, the argument to --cert is the name of a file containing
the certificate (the "fullchain.pem" file) for the website. In this
example, the magic name "unsafe-builtin" is used, which causes Fossil
to use a self-signed cert rather than a real cert obtained from a
[Certificate Authority](https://en.wikipedia.org/wiki/Certificate_authority)
or "CA". As the name implies, this self-signed cert is not secure and
should only be used for testing. Your web-browser will complain bitterly
and will refuse to display the pages using the "unsafe-builtin" cert.
Firefox will allow you to click an "I know the risks" button and continue.
Other web browsers will stubornly refuse to display the page, under the theory
that weak encryption is worse than no encryption at all. Continue reading
to see how to solve this.
## About Certs
Certs are based on public-key or asymmetric cryptography. To create a cert,
you first create a new "key pair" consisting of a public key and a private key.
The public key can be freely shared with the world, but you must keep the
private key secret. If anyone gains access to your private key then he will be
able to impersonate you and break into your system.
To obtain a cert, you send your public key and the name of the domain you
want to protect to a certificate authority. The CA then digitally signs
the combination of those two things using their own private key and sends
the signed combination back to you. The CA's digital signature of your
public key and domain name is the cert.
SSL/TLS servers need two things in order to prove their identity to clients:
1. The cert that was signed by a CA
2. The private key
The SSL/TLS servers send the cert to each client, so that the client
can verify it. But the private key is kept strictly private and is never
shared with anyone.
## How To Tell Fossil About Your Cert And Private Key
If you do not have your own cert and private key, you can ask Fossil
to use "unsafe-builtin", which is a self-signed cert that is built into
Fossil. This is wildly insecure, since the private key is not really private -
it is [in plain sight](/info/c2a7b14c3f541edb96?ln=89-116) in the Fossil
source tree for anybody to read. <b>Never add the private key that is
built into Fossil to your OS's trust store</b> as doing so will severely
compromise your computer. The built-in cert is only useful for testing.
If you want actual security, you will need to come up with your own private
key and cert.
Fossil wants to read certs and public keys in the
[PEM format](https://en.wikipedia.org/wiki/Privacy-Enhanced_Mail).
PEM is a pure ASCII text format. The private key consists of text
like this:
-----BEGIN PRIVATE KEY-----
*base-64 encoding of the private key*
-----END PRIVATE KEY-----
Similarly, a PEM-encoded cert will look like this:
-----BEGIN CERTIFICATE-----
*base-64 encoding of the certificate*
-----END CERTIFICATE-----
In both formats, text outside of the delimiters is ignored. That means
that if you have a PEM-formatted private key and a separate PEM-formatted
certificate, you can concatenate the two into a single file and the
individual components will still be easily accessible.
If you have a single file that holds both your private key and your
cert, you can hand it off to the "[fossil server](/help?cmd=server)"
command using the --cert option. Like this:
fossil server --port 443 --cert mycert.pem /home/www/myproject.fossil
The command above is sufficient to run a fully-encrypted web site for
the "myproject.fossil" Fossil repository. This command must be run as
root, since it wants to listen on TCP port 443, and only root processes are
allowed to do that. This is safe, however, since before reading any
information off of the wire, Fossil will put itself inside a chroot jail
at /home/www and drop all root privileges.
### Keeping The Cert And Private Key In Separate Files
If you do not want to combine your cert and private key into a single
big PEM file, you can keep them separate using the --pkey option to
Fossil.
fossil server --port 443 --cert fullchain.pem --pkey privkey.pem /home/www/myproject.fossil
## The ACME Protocol
The [ACME Protocol][2] is used to prove to a CA that you control a
website. CAs require proof that you control a domain before they
will issue a cert for that domain. The usual means of dealing
with ACME is to run the separate [certbot](https://certbot.eff.org) tool.
Here is, in a nutshell, what certbot will do to obtain your cert:
1. Certbot sends your "signing request" (the document that contains
your public key and your domain name) to the CA.
2. After receiving the signing request, the CA needs to verify that you
control the domain of the cert. To do this (or, one common
way of doing this, at least) the CA sends a secret token back to
certbot through a secure backchannel, and instructs certbot to make
that token accessible on the (unencrypted, ordinary "http:") web site
for the domain in a particular file under the ".well-known" subdirectory.
3. Certbot puts the token where the CA requested it, then notifies the
CA that it is there.
4. The CA accesses the token to confirm that you do indeed control the
website. It then creates the cert and sends it back to certbot.
5. Certbot stores your cert and deletes the ".well-known" token.
In order for all of this to happen, certbot needs to be able to create
a subdirectory named ".well-known", within a directory you specify, and
then populate that subdirectory with a token file of some kind. To support
this, the "[fossil server](/help?cmd=server)" and
"[fossil http](/help?cmd=http)" commands have the --acme option.
When the --acme option is specified and Fossil sees a URL where the path
begins with ".well-known", then instead of doing its normal processing, it
looks for a file with that pathname and returns it to the client. If
the "server" or "http" command is referencing a single Fossil repository,
then the ".well-known" sub-directory should be in the same directory as
the repository file. If the "server" or "http" command are run against
a directory full of Fossil repositories, then the ".well-known" sub-directory
should be in that top-level directory.
Thus, to set up a project website, you should first run Fossil in ordinary
unencrypted HTTP mode like this:
fossil server --port 80 --acme /home/www/myproject.fossil
Then you create your public/private key pair and run certbot, giving it
a --webroot of /home/www. Certbot will create the sub-directory
named "/home/www/.well-known" and put token files there, which the CA
will verify. Then certbot will store your new cert in a particular file.
Once certbot has obtained your cert, then you can concatenate that
cert with your private key and run Fossil in SSL/TLS mode as shown above.

<title>Securing a Repository with TLS</title>
<h2>Using TLS-Encrypted Communications with Fossil</h2>
If you are storing sensitive information in a repository accessible over
a network whose integrity you do not fully trust, you should use TLS to
encrypt all communications with it. This is most true for repositories
accessed over the Internet, especially if they will be accessed from
edge networks you do not control, since that admits of various forms of
[https://en.wikipedia.org/wiki/Man-in-the-middle_attack|man in the
middle attack].
TLS protects the credentials used to access the server, prevents
eavesdropping, prevents in-flight data modification, prevents server
identify spoofing, and more.
There are two major aspects to this, both of which have to be addressed
in different ways. Those are the subjects of the next two major
sections.
<h2 id="client">Client-Side Configuration</h2>
You can build Fossil against [https://www.openssl.org/ |
OpenSSL] to allow it to clone and sync with a remote
Fossil repository via <tt>https</tt> URIs.
<h3 id="openssl-bin">Building Against OpenSSL Automatically</h3>
The <tt>configure</tt> script will attempt to find OpenSSL on your
system automatically. It first tries asking the <tt>pkg-config</tt>
system where the OpenSSL development files are, and if that fails, it
falls back to looking through a list of likely directories.
If it can't find the files it needs, the most common solution is to
install the OpenSSL development package on your system via your OS's
package manager. Examples:
* <b>RHEL & Fedora</b>: <tt>sudo dnf install openssl-devel</tt>
* <b>Debian & Ubuntu</b>: <tt>sudo apt install libssl-dev</tt>
* <b>FreeBSD</b>: <tt>su -c 'pkg install openssl'</tt>
* <b>macOS</b>: <tt>sudo brew install openssl</tt>
* <b>Cygwin</b>: Install <tt>openssl-devel</tt> via Cygwin's
<tt>setup-*.exe</tt> program
The macOS case requires explanation. Apple last shipped OpenSSL
develpoment files in OS X 10.6 (Snow Leopard), choosing to deprecate it
from that point forward. (Apple wants you to use their proprietary
platform-specific encryption methods instead.) Since macOS has no
built-in package manager, a number have sprung up out of the FOSS world.
It is not known to this author whether Fossil's current build system can
find OpenSSL as installed with any of these other package managers, so
unless you have a particular reason to avoid it, we recomend that you
use [https://brew.sh|Homebrew] on macOS to install OpenSSL as above.
Fossil's build system will seek it out and use it automatically.
<h3 id="openssl-src">Building Against a Non-Platform Version of
OpenSSL</h3>
The Fossil build system has a few other methods for finding OpenSSL when
the automatic methods fail or when you'd prefer that Fossil use a
different version of OpenSSL than the one Fossil's build system picks on
its own.
A good reason to do this is when the Fossil build system finds a
functioning version of OpenSSL which is nevertheless unsuitable. One
common case is that your OS is sufficiently outdated that the platform
version of OpenSSL can no longer communicate with remote systems
adhering to the latest advice on secure communications. An old OpenSSL
might not support any of the
[https://en.wikipedia.org/wiki/Cipher_suite|cipher suites] the remote
Fossil repository's HTTPS proxy is willing to offer, for example, so
that even though both sides are speaking a variant of TLS/SSL, the peers
cannot come to an agreement on the cryptography.
If you've installed the OpenSSL development files somewhere that
Fossil's build system cannot find on its own, you can clue it in by
passing the <tt>--with-openssl</tt> option to the <tt>configure</tt>
script. Type <tt>./configure --help</tt> for details.
Another option is to download the source code to OpenSSL and build
Fossil against that private version of OpenSSL:
<pre>
cd compat # relative to the Fossil source tree root
tar xf /path/to/openssl-*.tar.gz
ln -fs openssl-x.y.z openssl
cd openssl
./config # or, e.g. ./Configure darwin64-x86_64-cc
make -j11
cd ../..
./configure --with-openssl=tree
make -j11
</pre>
That will get you a Fossil binary statically linked to this in-tree
version of OpenSSL.
Beware, taking this path typically opens you up to new problems, which
are conveniently covered in the next section!
<h3 id="certs">Certificates</h3>
To verify the identify of a server, TLS uses
[https://en.wikipedia.org/wiki/X.509#Certificates|X.509 certificates], a
scheme that depends on a trust hierarchy of so-called
[https://en.wikipedia.org/wiki/Certificate_authority | Certificate
Authorities]. The tree of trust relationships ultimately ends in the
CA roots, which are considered the ultimate arbiters of who to trust in
this scheme.
The question then is, what CA roots does Fossil trust?
If you are using a self-signed certificate, Fossil will initially not
know that it can trust your certificate, so you'll be asked if you want
to accept the certificate the first time you communicate with the
server. Verify the certificate fingerprint is correct, then answer
"always" if you want Fossil to remember your decision.
If you are cloning from or syncing to Fossil servers that use a
certificate signed by a well-known CA or one of its delegates, Fossil
still has to know which CA roots to trust. When this fails, you get an
error message that looks like this:
<pre>
Unable to verify SSL cert from fossil-scm.org
subject: CN = sqlite.org
issuer: C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
sha256: bf26092dd97df6e4f7bf1926072e7e8d200129e1ffb8ef5276c1e5dd9bc95d52
accept this cert and continue (y/N)?
</pre>
In older versions, the message was much longer and began with this line:
<pre>
SSL verification failed: unable to get local issuer certificate
</pre>
Fossil relies on the OpenSSL library to have some way to check a trusted
list of CA signing keys. There are two common ways this fails:
# The OpenSSL library Fossil is linked to doesn't have a CA
signing key set at all, so that it initially trusts no certificates
at all.
# The OpenSSL library does have a CA cert set, but your Fossil server's
TLS certificate was signed by a CA that isn't in that set.
A common reason to fall into the second trap is that you're using
certificates signed by a local private CA, as often happens in large
enterprises. You can solve this sort of problem by getting your local
CA's signing certificate in PEM format and pointing OpenSSL at it:
<pre>
fossil set --global ssl-ca-location /path/to/local-ca.pem
</pre>
The use of <tt>--global</tt> with this option is common, since you may
have multiple repositories served under certificates signed by that same
CA. However, if you have a mix of publicly-signed and locally-signed
certificates, you might want to drop the <tt>--global</tt> flag and set
this option on a per-repository basis instead.
A common way to run into the broader first problem is that you're on
FreeBSD, which does not install a CA certificate set by default, even as
a dependency of the OpenSSL library. If you're using a certificate
signed by one of the major public CAs, you can solve this by installing
the <tt>ca_root_nss</tt> package. That package contains the Mozilla NSS
certificate bundle, which gets installed in a location that OpenSSL
checks by default, so you don't need to change any Fossil settings.
(This is the same certificate set that ships with Firefox, by the way.)
The same sort of thing happens with the Windows build of OpenSSL, but
for a different core reason: Windows does ship with a stock CA
certificate set, but it's not in a format that OpenSSL understands how
to use. Rather than try to find a way to convert the data format, you
may find it acceptable to use the same Mozilla NSS cert set. I do not
know of a way to easily get this from Mozilla themselves, but I did find
a [https://curl.se/docs/caextract.html | third party source] for the
<tt>cacert.pem</tt> file. I suggest placing the file into your Windows
user home directory so that you can then point Fossil at it like so:
<pre>
fossil set --global ssl-ca-location %userprofile%\cacert.pem
</pre>
This can also happen if you've linked Fossil to a version of OpenSSL
[#openssl-src|built from source]. That same <tt>cacert.pem</tt> fix can
work in that case, too.
<blockquote>
OpenSSL 3.2.0 or greater is able to use the stock CA certificates
managed by Windows, and Fossil 2.25 (still in development as of
2024-07-15) takes advantage of this feature. This <em>possibly</em>
eliminates the need to manually install the Mozilla certificate package,
for example when connecting to Fossil servers secured by the widely-used
Let's Encrypt certificates. Run the following command to check if the
feature is supported:
<pre>
fossil tls-config show -v
</pre>
(See the "OpenSSL-winstore" section, requires Fossil 2.25 or greater.)
</blockquote>
When you build Fossil on Linux platforms against the binary OpenSSL
package provided with the OS, you typically get a root cert store along
with the platform OpenSSL package, either built-in or as a hard
dependency.
<h4>Client-Side Certificates</h4>
You can also use client side certificates to add an extra layer of
authentication, over and above Fossil's built in user management. If you
are particularly paranoid, you'll want to use this to remove the ability
of anyone on the internet from making any request to Fossil. Without
presenting a valid client side certificate, the web server won't invoke
the Fossil CGI handler.
Configure your server to request a client side certificate, and set up a
certificate authority to sign your client certificates. For each person
who needs to access the repository, create a private key and certificate
signed with that CA.
The PEM encoded private key and certificate should be stored in a single
file, simply by concatenating the key and certificate files. Specify the
location of this file with the <tt>ssl-identity</tt> setting, or the
<tt>--ssl-identity</tt> option to the <tt>clone</tt> command.
If you've password protected the private key, the password will be
requested every time you connect to the server. This password is not
stored by fossil, as doing so would defeat the purpose of having a
password.
If you attempt to connect to a server which requests a client
certificate, but don't provide one, fossil will show an error message
which explains what to do to authenticate with the server.
<h2 id="server">Server-Side Configuration</h2>
Before Fossil's built-in HTTP server gained [./ssl-server.md | TLS support],
system administrators that wanted to add this
had to put it behind a reverse proxy that would do the translation.
Since advantages remain for delegating TLS to another layer in the
stack, instructions for doing so continue to be included in our
documentation, such as:
* <a id="stunnel" href="./server/any/stunnel.md">Serving via stunnel</a>
* <a id="althttpd" href="./server/any/althttpd.md">Serving via stunnel + althttpd</a>
* <a id="nginx" href="./server/debian/nginx.md#tls">Serving via SCGI with nginx on Debian</a>
<h2 id="enforcing">Enforcing TLS Access</h2>
To use TLS encryption in cloning and syncing to a remote Fossil
repository, be sure to use the <tt>https:</tt> URI scheme in
<tt>clone</tt> and <tt>sync</tt> commands. If your server is configured
to serve the repository via both HTTP and HTTPS, it's easy to
accidentally use unencrypted HTTP if you forget the all-important 's'.
As of Fossil 2.9, using an <tt>http://</tt> URI with <tt>fossil
clone</tt> or <tt>sync</tt> on a site that forwards to HTTPS will cause
Fossil to remember the secure URL. However, there's a
[https://en.wikipedia.org/wiki/Trust_on_first_use | TOFU problem] with
this: it's still better to use <tt>https://</tt> from the start.
As of Fossil 2.8, there is a setting in the Fossil UI under Admin →
Access called "Redirect to HTTPS," which is set to "Off" by default.
Changing this only affects web UI access to the Fossil repository. It
doesn't affect clones and syncs done via the <tt>http</tt> URI scheme.
In Fossil 2.7 and earlier, there was a much weaker form of this setting
affecting the <tt>/login</tt> page only. If you're using this setting,
you should migrate to the new setting as soon as possible, because the
old setting allows multiple ways of defeating it.
<b id="rloop">WARNING:</b> Enabling HTTPS redirects at the Fossil repo
level while running Fossil behind an HTTPS proxy can result in an
infinite redirect loop. It happens when the proxy mechanism presents
"<tt>http</tt>" URIs to Fossil, so Fossil issues a redirect, so the browser
fetches the page again, causing Fossil to see an "<tt>http</tt>" URI again, so
it issues a redirect...'round and 'round it goes until the web browser
detects it's in a redirect loop and gives up. This problem prevents you
from getting back into the Admin UI to fix it, but there are several
ways to fix it:
# <b>Reset via CLI.</b> You can turn the setting back off from the
CLI with the command "<tt>fossil -R /path/to/repo.fossil set
redirect-to-https 0</tt>". (Currently doesn't work.)
# <b>Backup first.</b> This setting is stored in the Fossil
repository, so if you make a backup first <i>on the server</i>, you
can restore the repo file if enabling this feature creates a
redirect loop.
# <b>Download, fix, and restore.</b> You can copy the remote
repository file down to a local machine, use <tt>fossil ui</tt> to
fix the setting, and then upload it to the repository server
again.
It's best to enforce TLS-only access at the front-end proxy level
anyway. It not only avoids the problem entirely, it can be significantly
more secure. The [./server/debian/nginx.md#tls | nginx-on-Debian proxy guide] shows one way
to achieve this.
<h2>Terminology Note</h2>
This document is called <tt>ssl.wiki</tt> for historical reasons. The
TLS protocol was originally called SSL, and it went through several
revisions before being replaced by TLS. Years before this writing, SSL
finally became entirely obsolete due to weaknesses in the protocol fixed
in the later TLS series of protocols.
Some people still use the term "SSL" when they actually mean "TLS," but
in the Fossil project, we always use "TLS" except when we must preserve
some sort of historical compatibility, as with this document's name in
order to avoid broken external URLs. The Fossil TLS-related settings
also often use "<tt>ssl</tt>" in their names for the same reason.
This series of protocols is also called "HTTPS" after the URI scheme
used to specify "HTTP over TLS."

Does it use a lot of disk space or bandwidth? Is it scalable? In an attempt to answer these questions, this report looks at several projects that use fossil for configuration management and examines how well they are working. The following table is a summary of the results. (Last updated on 2018-06-04.) Explanation and analysis follows the table. <table> <tr> <th>Project</th> <th>Number Of Artifacts</th> <th>Number Of Check-ins</th> <th>Project Duration<br>(as of 2018-06-04)</th> <th>Uncompressed Size</th> <th>Repository Size</th> <th>Compression Ratio</th> <th>Clone Bandwidth</th> </tr> <tr align="center"> <td>[http://www.sqlite.org/src/timeline | SQLite] <td>77492 <td>20686 <td>6580 days<br>18.02 years <td>5.6 GB <td>70.0 MB <td>80:1 <td>51.1 MB </tr> <tr align="center"> <td>[http://core.tcl.tk/tcl/timeline | TCL] <td>161991 <td>23146 <td>7375 days<br>20.19 years <td>8.0 GB <td>222.0 MB <td>36:1 <td>150.5 MB </tr> <tr align="center"> <td>[/timeline | Fossil] <td>39148 <td>11266 <td>3971 days<br>10.87 years <td>3.8 GB <td>42.0 MB <td>90:1 <td>27.4 MB </tr> <tr align="center"> <td>[http://www.sqlite.org/slt/timeline | SLT] <td>2384 <td>169 <td>3474 days<br>9.51 years <td>2.1 GB <td>145.9 MB <td>14:1 <td>143.4 MB </tr> <tr align="center"> <td>[http://www.sqlite.org/th3.html | TH3] <td>12406 <td>3718 <td>3539 days<br>9.69 years <td>544 MB <td>18.0 MB <td>30:1 <td>14.7 MB </tr> <tr align="center"> <td>[http://www.sqlite.org/docsrc/timeline | SQLite Docs] <td>8752 <td>2783 <td>3857 days<br>10.56 years <td>349.9 MB <td>16.3 MB <td>21:1 <td>13.57 MB </tr> </table> <h2>Measured Attributes</h2> In Fossil, every version of every file, every wiki page, every change to every ticket, and every check-in is a separate "artifact". One way to think of a Fossil project is as a bag of artifacts. Of course, there is a lot more than this going on in Fossil. Many of the artifacts have meaning and are related to other artifacts. But at a low level (for example when synchronizing two instances of the same project) the only thing that matters is the unordered collection of artifacts. In fact, one of the key characteristics of Fossil is that the entire project history can be reconstructed simply by scanning the artifacts in an arbitrary order. The number of check-ins is the number of times that the "commit" command has been run. A single check-in might change 3 or 4 files, or it might change dozens or hundreds of files. Regardless of the number of files changed, it still only counts as one check-in. The "Uncompressed Size" is the total size of all the artifacts within the repository assuming they were all uncompressed and stored separately on the disk. Fossil makes use of delta compression between related versions of the same file, and then uses zlib compression on the resulting deltas. The total resulting repository size is shown after the uncompressed size. On the right end of the table, we show the "Clone Bandwidth". This is the total number of bytes sent from server back to the client. The number of bytes sent from client to server is negligible in comparison. These byte counts include HTTP protocol overhead. In the table and throughout this article, "GB" means gigabytes (10<sup><small>9</small></sup> bytes) not <a href="http://en.wikipedia.org/wiki/Gibibyte">gibibytes</a> (2<sup><small>30</small></sup> bytes). Similarly, "MB" and "KB" means megabytes and kilobytes, not mebibytes and kibibytes. <h2>Analysis And Supplemental Data</h2> Perhaps the two most interesting data points in the above table are SQLite and SLT. SQLite is a long-running project with long revision chains. Some of the files in SQLite have been edited over a thousand times. Each of these edits is stored as a delta, and hence the SQLite project gets excellent 80:1 compression. SLT, on the other hand, consists of many large (megabyte-sized) SQL scripts that have one or maybe two edits each. There is very little delta compression occurring and so the overall repository compression ratio is much lower. Note also that quite a bit more bandwidth is required to clone SLT than SQLite. For the first nine years of its development, SQLite was versioned by CVS. The resulting CVS repository measured over 320MB in size. So, the developers were surprised to see that the equivalent Fossil project (the first nine years on SQLite) would clone with only 13MB of bandwidth. The "sync" protocol used by fossil has turned out to be surprisingly efficient. A typical check-in on SQLite might use 3 or 4KB of network bandwidth. For example, the [04eef9522386a59e] check-in used a single HTTP request of 2099 bytes and got back a reply of 1116 bytes. The sync protocol is efficient enough that, once cloned, Fossil can easily be used over a dial-up connection. |

<title>Coding Style</title>
Fossil source code should follow the style guidelines below.
<em> The Fossil source tree includes a few files taken from external
sources
(examples: [https://github.com/antirez/linenoise|linenoise] and
[http://zlib.net/|zLib])
and this externally sourced code might not comply with these style guidelines.
</em>
<b>1. General points</b>:
<ol>
<li value=10> No line of code exceeds 80 characters in length. (Occasional
exceptions are made for HTML text on @-lines.)
<li> There are no tab characters.
<li> Line terminators are \n only. Do not use a \r\n line terminator.
<li> 2-space indentation is used. Remember: No tabs.
<li> Comments contain no spelling or grammatical errors. (Abbreviations
and sentence fragments are acceptable when trying to fit a comment
on a single line as long as the meaning is clear.)
<li> The tone of comments is professional and courteous. Comments
contain no profanity, obscenity, or innuendo.
<li> All C-code conforms to ANSI C-89.
Three well-defined existing exceptions are:
<ol type="a">
<li> -Wno-overlength-strings: The Fossil build system converts (some of the) source code comments
into strings, which may exceed the 509 character limit defined by ANSI.
(example: bld/page_index.h)
<li> -Wno-long-long: Fossil uses the 'long long' integer type, which is not strictly ANSI C-89 (defined in C99).
The use of 'long long' resolves many problems with 64-bit arithmetics, especially on 32-bit machines.
(http_ssl.c, sha3.c, shell.c, util.c)
<li> alloca(): By default, sqlite3.c was compiled with the -DSQLITE_USE_ALLOCA flag to use the alloca() function.
This is no longer the case as of 20220119. alloca() is not considered ANSI C, and normally not
recommended due to portability issues, but performance and/or memory consumption
improvement may have been a stronger argument in favor of its usage.
(sqlite3.c)
</ol>
<li> All comments and identifiers are in English.
<li> The program is single-threaded. Do not use threads.
(One exception to this is the HTTP server implementation for Windows,
which we do not know how to implement without the use of threads.)
</ol>
<b>2. C preprocessor macros</b>:
<ol>
<li value=20> The purpose of every preprocessor macros is clearly explained in a
comment associated with its definition.
<li> Every preprocessor macro is used at least once.
<li> The names of preprocessor macros clearly reflect their use.
<li> Assumptions about the relative values of related macros are
verified by asserts. Example: <tt>assert(READ_LOCK+1==WRITE_LOCK);</tt>
</ol>
<b>3. Function header comments</b>:
<ol>
<li value=30> Every function has a header comment describing the purpose and use
of the function.
<li> A function header comment defines the behavior of the function in
sufficient detail to allow the function to be re-implemented from
scratch without reference to the original code.
<li> Functions that perform dynamic memory allocation (either directly
or indirectly via subfunctions) say so in their header comments.
</ol>
<b>4. Function bodies</b>:
<ol>
<li value=40> The name of a function clearly reflects its purpose.
<li> Automatic variables are small, not large objects or arrays. Avoid
excessive stack usage.
<li> The check-list items for functions also apply to major subsections
within a function.
<li> All code subblocks are enclosed in {...}.
<li> <b>assert() macros are used as follows</b>:
<ol type="a">
<li> Function preconditions are clearly stated and verified by asserts.
<li> Invariants are identified by asserts.
</ol>
</ol>
<b>5. Class (struct) declarations</b>:
<ol>
<li value=50> The purpose and use of every class (a.k.a. structure) is clearly defined
in the header comment of its declaration.
<li> The purpose and use of every class member is clearly defined either
in the header comment of the class declaration or when the member is
declared or both.
<li> The names of class members clearly reflect their use.
<li> Invariants for classes are clearly defined.
</ol>
<b>6. Variables and class instances</b>:
<ol>
<li value=60> The purpose and use of every variable is defined by a comment at the
variable definition.
<li> The names of variables clearly reflect their use.
<li> Related variables have related names. (ex: aSavepoint and nSavepoint.)
<li> Variables have minimum practical scope.
<li> Automatic variables are small, not large objects or arrays.
<li> Constants are "const".
<li> Invariants on variables or groups of variables are defined and
tested by asserts.
<li> When a variable that refers to the same value is used within
multiple scopes, the same name is used in all cases.
<li> When variables refer to different values, different names are used
even when the names are in different scopes.
<li> Variable names with wide scope are sufficiently distinctive to allow
searching for them using grep.
</ol>

<title>The Fossil Sync Protocol</title>
This document describes the wire protocol used to synchronize
content between two Fossil repositories.
<h2>1.0 Overview</h2>
The global state of a fossil repository consists of an unordered
[./fileformat.wiki|collection of artifacts]. Each artifact is
identified by a cryptographic
hash of its content, expressed as a lower-case hexadecimal string.
Synchronization is the process of sharing artifacts between
repositories so that all repositories have copies of all artifacts. Because
artifacts are unordered, the order in which artifacts are received
is unimportant. It is assumed that the hash names
of artifacts are unique - that every artifact has a different hash.
To a first approximation, synchronization proceeds by sharing lists
of hashes for available artifacts, then sharing the content of artifacts
whose names are missing from one side or the other of the connection.
In practice, a repository might contain millions of artifacts. The list of
hash names for this many artifacts can be large. So optimizations are
employed that usually reduce the number of hashes that need to be
shared to a few dozen.
Each repository also has local state. The local state determines
the web-page formatting preferences, authorized users, ticket formats,
and similar information that varies from one repository to another.
The local state is not usually transferred during a sync. Except,
some local state is transferred during a [/help?cmd=clone|clone]
in order to initialize the local state of the new repository. Also,
an administrator can sync local state using
the [/help?cmd=configuration|config push] and
[/help?cmd=configuration|config pull]
commands.
<h3 id="crdt">1.1 Conflict-Free Replicated Datatypes</h3>
The "bag of artifacts" data model used by Fossil is apparently an
implementation of a particular
[https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type|Conflict-Free
Replicated Datatype (CRDT)] called a "G-Set" or "Grow-only Set". The
academic literature on CRDTs only began to appear in about 2011, and
Fossil predates that research by at least 4 years. But it is nice to
know that theorists have now proven that the underlying data model of
Fossil can provide strongly-consistent replicas using only
peer-to-peer communication and without any kind of central
authority.
If you are already familiar with CRDTs and were wondering if Fossil
used them, the answer is "yes". We just don't call them by that name.
<h2 id="transport">2.0 Transport</h2>
All communication between client and server is via HTTP requests.
The server is listening for incoming HTTP requests. The client
issues one or more HTTP requests and receives replies for each
request.
The server might be running as an independent server
using the [/help?cmd=server|"fossil server" command], or it
might be launched from inetd or xinetd using the
["fossil http" command|/help?cmd=http]. Or the server might
be [./server/any/cgi.md|launched from CGI] or from
[./server/any/scgi.md|SCGI].
(See "[./server/|How To Configure A Fossil Server]" for details.)
The specifics of how the server listens
for incoming HTTP requests is immaterial to this protocol.
The important point is that the server is listening for requests and
the client is the issuer of the requests.
A single [/help?cmd=push|push],
[/help?cmd=pull|pull], or [/help?cmd=sync|sync]
might involve multiple HTTP requests.
The client maintains state between all requests. But on the server
side, each request is independent. The server does not preserve
any information about the client from one request to the next.
Note: Throughout this article, we use the terms "server" and "client"
to represent the listener and initiator of the interaction, respectively.
Nothing in this protocol requires that the server actually be a back-room
processor housed in a datacenter, nor does the client need to be a desktop
or handheld device. For the purposes of this article "client" simply means
the repository that initiates the conversation and "server" is the repository
that responds. Nothing more.
<h4 id="https">2.0.1 HTTPS Transport</h4>
HTTPS differs from HTTP only in that the HTTPS protocol is
encrypted as it travels over the wire. The underlying protocol
is the same. This document describes only the underlying, unencrypted
messages that go client to server and back to client.
Whether or not those messages are encrypted does not come into play
in this document.
Fossil includes built-in
[./ssl-server.md|support for HTTPS encryption] in both client and server.
<h4 id="ssh">2.0.2 SSH Transport</h4>
When doing a sync using an "<code>ssh:…</code>" URL, the same HTTP transport protocol
is used. Fossil simply uses [https://en.wikipedia.org/wiki/Secure_Shell|ssh]
to start an instance of the [/help?cmd=test-http|fossil test-http] command
running on the remote machine. It then sends HTTP requests and gets back HTTP
replies over the SSH connection, rather than sending and receiving over an
internet socket. To see the specific "ssh" command that the Fossil client
runs in order to set up a connection, add either of the the "--httptrace" or
"--sshtrace" options to the "fossil sync" command line.
This method is dependent on the remote <var>PATH</var> set by the SSH
daemon, which may not be the same as your interactive shell's
<var>PATH</var> on that same server. It is common to find
<var>$HOME/bin</var> in the latter but not the former, for instance,
leading to failures to sync over <code>ssh:…</code> URLs when you
install the <code>fossil</code> binary in a nonstandard location, as
with
<verbatim>./configure --prefix=$HOME && make install</verbatim>
The simpler of the two solutions to this problem is to install Fossil
where sshd expects to find it, but when that isn't an option, you can
instead give a URL like this:
<verbatim>fossil clone ssh://myserver.example.com/path/to/repo.fossil?fossil=/home/me/bin/fossil</verbatim>
That gives the local Fossil instance the absolute path to the binary on
the remote machine for use when calling that Fossil instance through the
SSH tunnel.
<h4 id="file">2.0.3 FILE Transport</h4>
When doing a sync using a "file:..." URL, the same HTTP protocol is
still used. But instead of sending each HTTP request over a socket or
via SSH, the HTTP request is written into a temporary file. The client
then invokes the [/help?cmd=http|fossil http] command in a subprocess
to process the request and and generate a reply. The client then reads
the HTTP reply out of a temporary file on disk, and deletes the two
temporary files. To see the specific "fossil http" command that is run
in order to implement the "file:" transport, add the "--httptrace"
option to the "fossil sync" command.
<h3 id="srv-id">2.1 Server Identification</h3>
The server is identified by a URL argument that accompanies the
push, pull, or sync command on the client. (As a convenience to
users, the URL can be omitted on the client command and the same URL
from the most recent push, pull, or sync will be reused. This saves
typing in the common case where the client does multiple syncs to
the same server.)
The client modifies the URL by appending the method name "<b>/xfer</b>"
to the end. For example, if the URL specified on the client command
line is
<pre>https://fossil-scm.org/fossil</pre>
Then the URL that is really used to do the synchronization will
be:
<pre>https://fossil-scm.org/fossil/xfer</pre>
<h3 id="req-format">2.2 HTTP Request Format</h3>
The client always sends a POST request to the server. The
general format of the POST request is as follows:
<pre>
POST /fossil/xfer HTTP/1.0
Host: fossil-scm.hwaci.com:80
Content-Type: application/x-fossil
Content-Length: 4216
</pre>
<i><pre>content...</pre></i>
In the example above, the pathname given after the POST keyword
on the first line is a copy of the URL pathname. The Host: parameter
is also taken from the URL. The content type is always either
"application/x-fossil" or "application/x-fossil-debug". The "x-fossil"
content type is the default. The only difference is that "x-fossil"
content is compressed using zlib whereas "x-fossil-debug" is sent
uncompressed.
A typical reply from the server might look something like this:
<pre>
HTTP/1.0 200 OK
Date: Mon, 10 Sep 2007 12:21:01 GMT
Connection: close
Cache-control: private
Content-Type: application/x-fossil; charset=US-ASCII
Content-Length: 265
</pre>
<i><pre>content...</pre></i>
The content type of the reply is always the same as the content type
of the request.
<h2 id="content">3.0 Fossil Synchronization Content</h2>
A synchronization request between a client and server consists of
one or more HTTP requests as described in the previous section. This
section details the "x-fossil" content type.
<h3 id="lines">3.1 Line-oriented Format</h3>
The x-fossil content type consists of zero or more "cards". Cards
are separated by the newline character ("\n"). Leading and trailing
whitespace on a card is ignored. Blank cards are ignored.
Each card is divided into zero or more space separated tokens.
The first token on each card is the operator. Subsequent tokens
are arguments. The set of operators understood by servers is slightly
different from the operators understood by clients, though the two
are very similar.
<h3 id="login">3.2 Login Cards</h3>
Every message from client to server begins with one or more login
cards. Each login card has the following format:
<pre><b>login</b> <i>userid nonce signature</i></pre>
The userid is the name of the user that is requesting service
from the server. The nonce is the SHA1 hash of the remainder of
the message - all text that follows the newline character that
terminates the login card. The signature is the SHA1 hash of
the concatenation of the nonce and the users password.
For each login card, the server looks up the user and verifies
that the nonce matches the SHA1 hash of the remainder of the
message. It then checks the signature hash to make sure the
signature matches. If everything
checks out, then the client is granted all privileges of the
specified user.
Privileges are cumulative. There can be multiple successful
login cards. The session privilege is the union of all
privileges from all login cards.
<h3 id="file">3.3 File Cards</h3>
Artifacts are transferred using either "file" cards, or "cfile"
or "uvfile" cards.
The name "file" card comes from the fact that most artifacts correspond to
files that are under version control.
The "cfile" name is an abbreviation for "compressed file".
The "uvfile" name is an abbreviation for "unversioned file".
<h4 id="ordinary-fc">3.3.1 Ordinary File Cards</h4>
For sync protocols, artifacts are transferred using "file"
cards. File cards come in two different formats depending
on whether the artifact is sent directly or as a
[./delta_format.wiki|delta] from some
other artifact.
<pre>
<b>file</b> <i>artifact-id size</i> <b>\n</b> <i>content</i>
<b>file</b> <i>artifact-id delta-artifact-id size</i> <b>\n</b> <i>content</i>
</pre>
File cards are followed by in-line "payload" data.
The content of the artifact
or the artifact delta is the first <i>size</i> bytes of the
x-fossil content that immediately follow the newline that
terminates the file card.
The first argument of a file card is the ID of the artifact that
is being transferred. The artifact ID is the lower-case hexadecimal
representation of the name hash for the artifact.
The last argument of the file card is the number of bytes of
payload that immediately follow the file card. If the file
card has only two arguments, that means the payload is the
complete content of the artifact. If the file card has three
arguments, then the payload is a
[./delta_format.wiki|delta] and the second argument is
the ID of another artifact that is the source of the delta.
File cards are sent in both directions: client to server and
server to client. A delta might be sent before the source of
the delta, so both client and server should remember deltas
and be able to apply them when their source arrives.
<h4 id="compressed-fc">3.3.2 Compressed File Cards</h4>
A client that sends a clone protocol version "3" or greater will
receive artifacts as "cfile" cards while cloning. This card was
introduced to improve the speed of the transfer of content by sending the
compressed artifact directly from the server database to the client.
Compressed File cards are similar to File cards, sharing the same
in-line "payload" data characteristics and also the same treatment of
direct content or delta content. Cfile cards come in two different formats
depending on whether the artifact is sent directly or as a delta from
some other artifact.
<pre>
<b>cfile</b> <i>artifact-id usize csize</i> <b>\n</b> <i>content</i>
<b>cfile</b> <i>artifact-id delta-artifact-id usize csize</i> <b>\n</b> <i>content</i>
</pre>
The first argument of the cfile card is the ID of the artifact that
is being transferred. The artifact ID is the lower-case hexadecimal
representation of the name hash for the artifact. The second argument of
the cfile card is the original size in bytes of the artifact. The last
argument of the cfile card is the number of compressed bytes of payload
that immediately follow the cfile card. If the cfile card has only
three arguments, that means the payload is the complete content of the
artifact. If the cfile card has four arguments, then the payload is a
delta and the second argument is the ID of another artifact that is the
source of the delta and the third argument is the original size of the
delta artifact.
Unlike file cards, cfile cards are only sent in one direction during a
clone from server to client for clone protocol version "3" or greater.
<h4 id="private">3.3.3 Private artifacts</h4>
"Private" content consist of artifacts that are not normally synced.
However, private content will be synced when the
the [/help?cmd=sync|fossil sync] command includes the "--private" option.
Private content is marked by a "private" card:
<pre><b>private</b></pre>
The private card has no arguments and must directly precede a
file card that contains the private content.
<h4 id="uv-fc">3.3.4 Unversioned File Cards</h4>
Unversioned content is sent in both directions (client to server and
server to client) using "uvfile" cards in the following format:
<pre><b>uvfile</b> <i>name mtime hash size flags</i> <b>\n</b> <i>content</i></pre>
The <i>name</i> field is the name of the unversioned file. The
<i>mtime</i> is the last modification time of the file in seconds
since 1970. The <i>hash</i> field is the hash of the content
for the unversioned file, or "<b>-</b>" for deleted content.
The <i>size</i> field is the (uncompressed) size of the content
in bytes. The <i>flags</i> field is an integer which is interpreted
as an array of bits. The 0x0004 bit of <i>flags</i> indicates that
the <i>content</i> is to be omitted. The content might be omitted if
it is too large to transmit, or if the sender merely wants to update the
modification time of the file without changing the files content.
The <i>content</i> is the (uncompressed) content of the file.
The receiver should only accept the uvfile card if the hash and
size match the content and if the mtime is newer than any existing
instance of the same file held by the receiver. The sender will not
normally transmit a uvfile card unless all these constraints are true,
but the receiver should double-check.
A server will only accept uvfile cards if the login user has
the "y" write-unversioned permission.
Servers send uvfile cards in response to uvgimme cards received from
the client. Clients send uvfile cards when they determine that the server
needs the content based on uvigot cards previously received from the server.
<h3 id="push" name="pull">3.4 Push and Pull Cards</h3>
Among the first cards in a client-to-server message are
the push and pull cards. The push card tells the server that
the client is pushing content. The pull card tells the server
that the client wants to pull content. In the event of a sync,
both cards are sent. The format is as follows:
<pre>
<b>push</b> <i>servercode projectcode</i>
<b>pull</b> <i>servercode projectcode</i>
</pre>
The <i>servercode</i> argument is the repository ID for the
client. The <i>projectcode</i> is the identifier
of the software project that the client repository contains.
The projectcode for the client and server must match in order
for the transaction to proceed.
The server will also send a push card back to the client
during a clone. This is how the client determines what project
code to put in the new repository it is constructing.
The <i>servercode</i> argument is currently unused.
<h3 id="clones">3.5 Clone Cards</h3>
A clone card works like a pull card in that it is sent from
client to server in order to tell the server that the client
wants to pull content. The clone card comes in two formats. Older
clients use the no-argument format and newer clients use the
two-argument format.
<pre>
<b>clone</b>
<b>clone</b> <i>protocol-version sequence-number</i>
</pre>
<h4>3.5.1 Protocol 3</h4>
The latest clients send a two-argument clone message with a
protocol version of "3". (Future versions of Fossil might use larger
protocol version numbers.) Version "3" of the protocol enhanced version
"2" by introducing the "cfile" card which is intended to speed up clone
operations. Instead of sending "file" cards, the server will send "cfile"
cards
<h4>3.5.2 Protocol 2</h4>
The sequence-number sent is the number
of artifacts received so far. For the first clone message, the
sequence number is 0. The server will respond by sending file
cards for some number of artifacts up to the maximum message size.
The server will also send a single "clone_seqno" card to the client
so that the client can know where the server left off.
<pre>
<b>clone_seqno</b> <i>sequence-number</i>
</pre>
The clone message in subsequent HTTP requests for the same clone
operation will use the sequence-number from the
clone_seqno of the previous reply.
In response to an initial clone message, the server also sends the client
a push message so that the client can discover the projectcode for
this project.
<h4>3.5.3 Legacy Protocol</h4>
Older clients send a clone card with no argument. The server responds
to a blank clone card by sending an "igot" card for every artifact in the
repository. The client will then issue "gimme" cards to pull down all the
content it needs.
The legacy protocol works well for smaller repositories (50MB with 50,000
artifacts) but is too slow and unwieldy for larger repositories.
The version 2 protocol is an effort to improve performance. Further
performance improvements with higher-numbered clone protocols are
possible in future versions of Fossil.
<h3 id="igot">3.6 Igot Cards</h3>
An igot card can be sent from either client to server or from
server to client in order to indicate that the sender holds a copy
of a particular artifact. The format is:
<pre>
<b>igot</b> <i>artifact-id</i> ?<i>flag</i>?
</pre>
The first argument of the igot card is the ID of the artifact that
the sender possesses.
The receiver of an igot card will typically check to see if
it also holds the same artifact and if not it will request the artifact
using a gimme card in either the reply or in the next message.
If the second argument exists and is "1", then the artifact
identified by the first argument is private on the sender and should
be ignored unless a "--private" [/help?cmd=sync|sync] is occurring.
The name "igot" comes from the English slang expression "I got" meaning
"I have".
<h4>3.6.1 Unversioned Igot Cards</h4>
Zero or more "uvigot" cards are sent from server to client when
synchronizing unversioned content. The format of a uvigot card is
as follows:
<pre>
<b>uvigot</b> <i>name mtime hash size</i>
</pre>
The <i>name</i> argument is the name of an unversioned file.
The <i>mtime</i> is the last modification time of the unversioned file
in seconds since 1970.
The <i>hash</i> is the SHA1 or SHA3-256 hash of the unversioned file
content, or "<b>-</b>" if the file has been deleted.
The <i>size</i> is the uncompressed size of the file in bytes.
When the server sees a "pragma uv-hash" card for which the hash
does not match, it sends uvigot cards for every unversioned file that it
holds. The client will use this information to figure out which
unversioned files need to be synchronized.
The server might also send a uvigot card when it receives a uvgimme card
but its reply message size is already oversized and hence unable to hold
the usual uvfile reply.
When a client receives a "uvigot" card, it checks to see if the
file needs to be transferred from client to server or from server to client.
If a client-to-server transmission is needed, the client schedules that
transfer to occur on a subsequent HTTP request. If a server-to-client
transfer is needed, then the client sends a "uvgimme" card back to the
server to request the file content.
<h3 id="gimme">3.7 Gimme Cards</h3>
A gimme card is sent from either client to server or from server
to client. The gimme card asks the receiver to send a particular
artifact back to the sender. The format of a gimme card is this:
<pre>
<b>gimme</b> <i>artifact-id</i>
</pre>
The argument to the gimme card is the ID of the artifact that
the sender wants. The receiver will typically respond to a
gimme card by sending a file card in its reply or in the next
message.
The "gimme" name means "give me". The imperative "give me" is
pronounced as if it were a single word "gimme" in some dialects of
English (including the dialect spoken by the original author of Fossil).
<h4>3.7.1 Unversioned Gimme Cards</h4>
When synchronizing unversioned content, the client may send "uvgimme"
cards to the server. A uvgimme card requests that the server send
unversioned content to the client. The format of a uvgimme card is
as follows:
<pre>
<b>uvgimme</b> <i>name</i>
</pre>
The <i>name</i> is the name of the unversioned file found on the
server that the client would like to have. When a server sees a
uvgimme card, it normally responses with a uvfile card, though it might
also send another uvigot card if the HTTP reply is already oversized.
<h3 id="cookie">3.8 Cookie Cards</h3>
A cookie card can be used by a server to record a small amount
of state information on a client. The server sends a cookie to the
client. The client sends the same cookie back to the server on
its next request. The cookie card has a single argument which
is its payload.
<pre>
<b>cookie</b> <i>payload</i>
</pre>
The client is not required to return the cookie to the server on
its next request. Or the client might send a cookie from a different
server on the next request. So the server must not depend on the
cookie and the server must structure the cookie payload in such
a way that it can tell if the cookie it sees is its own cookie or
a cookie from another server. (Typically the server will embed
its servercode as part of the cookie.)
<h3 id="reqconfig">3.9 Request-Configuration Cards</h3>
A request-configuration or "reqconfig" card is sent from client to
server in order to request that the server send back "configuration"
data. "Configuration" data is information about users or website
appearance or other administrative details which are not part of the
persistent and versioned state of the project. For example, the "name"
of the project, the default Cascading Style Sheet (CSS) for the web-interface,
and the project logo displayed on the web-interface are all configuration
data elements.
The reqconfig card is normally sent in response to the
"fossil configuration pull" command. The format is as follows:
<pre>
<b>reqconfig</b> <i>configuration-name</i>
</pre>
As of 2024-10-22, the configuration-name must be one of the
following values:

</table>
New configuration-names are likely to be added in future releases of
Fossil. If the server receives a configuration-name that it does not
understand, the entire reqconfig card is silently ignored. The reqconfig
card might also be ignored if the user lacks sufficient privilege to
access the requested information.
The configuration-names that begin with an alphabetic character refer
to values in the "config" table of the server database. For example,
the "logo-image" configuration item refers to the project logo image
that is configured on the Admin page of the [./webui.wiki | web-interface].
The value of the configuration item is returned to the client using a
"config" card.
If the configuration-name begins with "@", that refers to a class of
values instead of a single value. The content of these configuration items
is returned in a "config" card that contains pure SQL text that is
intended to be evaluated by the client.
The @user and @concealed configuration items contain sensitive information
and are ignored for clients without sufficient privilege.
<h3 id="config">3.10 Configuration Cards</h3>
A "config" card is used to send configuration information from client
to server (in response to a "fossil configuration push" command) or
from server to client (in response to a "fossil configuration pull" or
"fossil clone" command). The format is as follows:
<pre>
<b>config</b> <i>configuration-name size</i> <b>\n</b> <i>content</i>
</pre>
The server will only accept a config card if the user has
"Admin" privilege. A client will only accept a config card if
it had sent a corresponding reqconfig card in its request.
The content of the configuration item is used to overwrite the
corresponding configuration data in the receiver.
<h3 id="pragma">3.11 Pragma Cards</h3>
The client may try to influence the behavior of the server by
issuing a pragma card:
<pre>
<b>pragma</i> <i>name value...</i>
</pre>
The "pragma" card has at least one argument which is the pragma name.
The pragma name defines what the pragma does.
A pragma might have zero or more "value" arguments
depending on the pragma name.
New pragma names may be added to the protocol from time to time
in order to enhance the capabilities of Fossil.
Unknown pragmas are silently ignored, for backwards compatibility.
The following are the known pragma names as of 2019-06-30:
<ol>
<li><b>send-private</b> The send-private pragma instructs the server to send all of its
private artifacts to the client. The server will only obey this
request if the user has the "x" or "Private" privilege.
<li><b>send-catalog</b> The send-catalog pragma instructs the server to transmit igot
cards for every known artifact. This can help the client and server
to get back in synchronization after a prior protocol error. The
"--verily" option to the [/help?cmd=sync|fossil sync] command causes
the send-catalog pragma to be transmitted.
<li><b>uv-hash</b> <i>HASH</i> The uv-hash pragma is sent from client to server to provoke a
synchronization of unversioned content. The <i>HASH</i> is a SHA1
hash of the names, modification times, and individual hashes of all
unversioned files on the client. If the unversioned content hash
from the client does not match the unversioned content hash on the
server, then the server will reply with either a "pragma uv-push-ok"
or "pragma uv-pull-only" card followed by one "uvigot" card for
each unversioned file currently held on the server. The collection
of "uvigot" cards sent in response to a "uv-hash" pragma is called
the "unversioned catalog". The client will used the unversioned
catalog to figure out which files (if any) need to be synchronized
between client and server and send appropriate "uvfile" or "uvgimme"
cards on the next HTTP request.
If a client sends a uv-hash pragma and does not receive back
either a uv-pull-only or uv-push-ok pragma, that means that the
content on the server exactly matches the content on the client and
no further synchronization is required.
<li><b>uv-pull-only</b></i> A server sends the uv-pull-only pragma to the client in response
to a uv-hash pragma with a mismatched content hash argument. This
pragma indicates that there are differences in unversioned content
between the client and server but that content can only be transferred
from server to client. The server is unwilling to accept content from
the client because the client login lacks the "write-unversioned"
permission.
<li><b>uv-push-ok</b></i> A server sends the uv-push-ok pragma to the client in response
to a uv-hash pragma with a mismatched content hash argument. This
pragma indicates that there are differences in unversioned content
between the client and server and that content can be transferred
in either direction. The server is willing to accept content from
the client because the client login has the "write-unversioned"
permission.
<li><b>ci-lock</b> <i>CHECKIN-HASH CLIENT-ID</i> A client sends the "ci-lock" pragma to the server to indicate
that it is about to add a new check-in as a child of the
CHECKIN-HASH check-in and on the same branch as CHECKIN-HASH.
If some other client has already indicated that it was also
trying to commit against CHECKIN-HASH, that indicates that a
fork is about to occur, and the server will reply with
a "ci-lock-fail" pragma (see below). Check-in locks
automatically expire when the check-in actually occurs, or
after a timeout (currently one minute but subject to change).
<li><b>ci-lock-fail</b> <i>LOGIN MTIME</i> When a server receives two or more "ci-lock" pragma messages
for the same check-in but from different clients, the second a
subsequent ci-lock will provoke a ci-lock-fail pragma in the
reply to let the client know that it if continues with the
check-in it will likely generate a fork. The LOGIN and MTIME
arguments are intended to provide information to the client to
help it generate a more useful error message.
<li><b>ci-unlock</b> <i>CLIENT-ID</i> A client sends the "ci-unlock" pragma to the server after
a successful commit. This instructs the server to release
any lock on any check-in previously held by that client.
The ci-unlock pragma helps to avoid false-positive lock warnings
that might arise if a check-in is aborted and then restarted
on a branch.
</ol>
<h3 id="comment">3.12 Comment Cards</h3>
Any card that begins with "#" (ASCII 0x23) is a comment card and
is silently ignored.
<h3 id="error">3.13 Message and Error Cards</h3>
If the server discovers anything wrong with a request, it generates
an error card in its reply. When the client sees the error card,
it displays an error message to the user and aborts the sync
operation. An error card looks like this:
<pre>
<b>error</b> <i>error-message</i>
</pre>
The error message is English text that is encoded in order to
be a single token.
A space (ASCII 0x20) is represented as "\s" (ASCII 0x5C, 0x73). A
newline (ASCII 0x0a) is "\n" (ASCII 0x6C, x6E). A backslash
(ASCII 0x5C) is represented as two backslashes "\\". Apart from
space and newline, no other whitespace characters nor any
unprintable characters are allowed in
the error message.
The server can also send a message card that also prints a
message on the client console, but which is not an error:
<pre>
<b>message</b> <i>message-text</i>
</pre>
The message-text uses the same format as an error message.
<h3 id="unknown">3.14 Unknown Cards</h3>
If either the client or the server sees a card that is not
described above, then it generates an error and aborts.
<h2 id="phantoms" name="clusters">4.0 Phantoms And Clusters</h2>
When a repository knows that an artifact exists and knows the ID of
that artifact, but it does not know the artifact content, then it stores that
artifact as a "phantom". A repository will typically create a phantom when
it receives an igot card for an artifact that it does not hold or when it
receives a file card that references a delta source that it does not
hold. When a server is generating its reply or when a client is
generating a new request, it will usually send gimme cards for every
phantom that it holds.
A cluster is a special artifact that tells of the existence of other
artifacts. Any artifact in the repository that follows the syntactic rules
of a cluster is considered a cluster.
A cluster is line oriented. Each line of a cluster
is a card. The cards are separated by the newline ("\n") character.
Each card consists of a single character card type, a space, and a
single argument. No extra whitespace and no trailing or leading
whitespace is allowed. All cards in the cluster must occur in
strict lexicographical order.
A cluster consists of one or more "M" cards followed by a single
"Z" card. Each M card holds an argument which is an artifact ID for an
artifact in the repository. The Z card has a single argument which is the
lower-case hexadecimal representation of the MD5 checksum of all
preceding M cards up to and included the newline character that
occurred just before the Z that starts the Z card.
Any artifact that does not match the specifications of a cluster
exactly is not a cluster. There must be no extra whitespace in
the artifact. There must be one or more M cards. There must be a
single Z card with a correct MD5 checksum. And all cards must
be in strict lexicographical order.
<h3 id="unclustered">4.1 The Unclustered Table</h3>
Every repository maintains a table named "<b>unclustered</b>"
which records the identity of every artifact and phantom it holds that is not
mentioned in a cluster. The entries in the unclustered table can
be thought of as leaves on a tree of artifacts. Some of the unclustered
artifacts will be other clusters. Those clusters may contain other clusters,
which might contain still more clusters, and so forth. Beginning
with the artifacts in the unclustered table, one can follow the chain
of clusters to find every artifact in the repository.
<h2 id="strategies">5.0 Synchronization Strategies</h2>
<h3 id="pull-strategy">5.1 Pull</h3>
A typical pull operation proceeds as shown below. Details
of the actual implementation may vary slightly but the gist of
a pull is captured in the following steps:
<ol>
<li>The client sends login and pull cards.
<li>The client sends a cookie card if it has previously received a cookie.
<li>The client sends gimme cards for every phantom that it holds.
<hr>
<li>The server checks the login password and rejects the session if

The first three steps are the processing that occurs on the client to generate the request. The middle four steps are processing that occurs on the server to interpret the request and generate a reply. And the last three steps are the processing that the client does to interpret the reply. During a pull, the client will keep sending HTTP requests until it holds all artifacts that exist on the server. Note that the server tries to limit the size of its reply message to something reasonable (usually about 1MB) so that it might stop sending file cards as described in step (6) if the reply becomes too large. Step (5) is the only way in which new clusters can be created. By only creating clusters on the server, we hope to minimize the amount of overlap between clusters in the common configuration where there is a single server and many clients. The same synchronization protocol will continue to work even if there are multiple servers or if servers and clients sometimes change roles. The only negative effects of these unusual arrangements is that more than the minimum number of clusters might be generated. <h3 id="push-stragegy">5.2 Push</h3> A typical push operation proceeds roughly as shown below.

it does not possess.
<li>The server issues gimme cards for all phantoms.
<hr>
<li>The client remembers the gimme cards from the server so that it
can generate file cards in reply on the next cycle.
</ol>
As with a pull, the steps of a push operation repeat until the
server knows all artifacts that exist on the client. Also, as with
pull, the client attempts to keep the size of the request from
growing too large by suppressing file cards once the
size of the request reaches 1MB.
<h3 id="sync-strategy">5.3 Sync</h3>
A sync is just a pull and a push that happen at the same time.
The first three steps of a pull are combined with the first five steps
of a push. Steps (4) through (7) of a pull are combined with steps
(5) through (8) of a push. And steps (8) through (10) of a pull
are combined with step (9) of a push.
<h3 id="uv-strategy">5.4 Unversioned File Sync</h3>
"Unversioned files" are files held in the repository
where only the most recent version of the file is kept rather than
the entire change history. Unversioned files are intended to be
used to store ephemeral content, such as compiled binaries of the
most recent release.
Unversioned files are identified by name and timestamp (mtime).
Only the most recent version of each file (the version with
the largest mtime value) is retained.
Unversioned files are synchronized using the
[/help?cmd=unversioned|fossil unversioned sync] command.
A schematic of an unversioned file synchronization is as follows:
<ol>
<li>The client sends a "pragma uv-hash" card to the server. The argument
to the uv-hash pragma is a hash of all filesnames, mtimes, and
content hashes for the unversioned files held by the client.
<hr>
<li>If the unversioned content hash from the client matches the unversioned
content hash on the server, then nothing needs to be done and the
server no-ops. But if the hashes are different, then the server
replies with either a uv-pull-only or a uv-push-ok pragma followed by
uvigot cards for all unversioned files held on the server.
<hr>
<li>The client examines the uvigot cards received from the server and
determines which unversioned files need to be exchanged in order
to bring the client and server into synchronization. The client
then sends appropriate "uvgimme" or "uvfile" cards back to the
server.
<hr>
<li>The server updates its unversioned file store with received "uvfile"
cards and answers "uvgimme" cards with "uvfile" cards in its reply.
</ol>
The last two steps might be repeated multiple
times if there is more unversioned content to be transferred than will
fit comfortably in a single HTTP request.
<h2 id="summary">6.0 Summary</h2>
Here are the key points of the synchronization protocol:
<ol>
<li>The client sends one or more PUSH HTTP requests to the server.
The request and reply content type is "application/x-fossil".
<li>HTTP request content is compressed using zlib.
<li>The content of request and reply consists of cards with one
card per line.
<li>Card formats are:
<ul>
<li> <b>login</b> <i>userid nonce signature</i>
<li> <b>push</b> <i>servercode projectcode</i>
<li> <b>pull</b> <i>servercode projectcode</i>
<li> <b>clone</b>
<li> <b>clone_seqno</b> <i>sequence-number</i>
<li> <b>file</b> <i>artifact-id size</i> <b>\n</b> <i>content</i>
<li> <b>file</b> <i>artifact-id delta-artifact-id size</i> <b>\n</b> <i>content</i>
<li> <b>cfile</b> <i>artifact-id size</i> <b>\n</b> <i>content</i>
<li> <b>cfile</b> <i>artifact-id delta-artifact-id size</i> <b>\n</b> <i>content</i>
<li> <b>uvfile</b> <i>name mtime hash size flags</i> <b>\n</b> <i>content</i>
<li> <b>private</b>
<li> <b>igot</b> <i>artifact-id</i> ?<i>flag</i>?
<li> <b>uvigot</b> <i>name mtime hash size</i>
<li> <b>gimme</b> <i>artifact-id</i>
<li> <b>uvgimme</b> <i>name</i>
<li> <b>cookie</b> <i>cookie-text</i>
<li> <b>reqconfig</b> <i>parameter-name</i>
<li> <b>config</b> <i>parameter-name size</i> <b>\n</b> <i>content</i>
<li> <b>pragma</b> <i>name</i> <i>value...</i>
<li> <b>error</b> <i>error-message</i>
<li> <b>message</b> <i>text-messate</i>
<li> <b>#</b> <i>arbitrary-text...</i>
</ul>
<li>Phantoms are artifacts that a repository knows exist but does not possess.
<li>Clusters are artifacts that contain IDs of other artifacts.
<li>Clusters are created automatically on the server during a pull.
<li>Repositories keep track of all artifacts that are not named in any
cluster and send igot messages for those artifacts.
<li>Repositories keep track of all the phantoms they hold and send
gimme messages for those artifacts.
</ol>
<h2 id="troubleshooting">7.0 Troubleshooting And Debugging Hints</h2>
If you run the [/help?cmd=sync|fossil sync] command
(or [/help?cmd=pull|pull] or [/help?cmd=push|push] or
[/help?cmd=clone|clone]) with the --httptrace option, Fossil
will keep a copy of each HTTP request and reply in files
named:
<ul>
<li> <tt>http-request-</tt><i>N</i><tt>.txt</tt>
<li> <tt>http-reply-</tt><i>N</i><tt>.txt</tt>
</ul>
In the above, <i>N</i> is an integer that increments with each
round-trip. If you are having trouble on the server side,
you can run the "[/help?cmd=test-http|fossil test-http]" command in a
debugger using one the "http-request-N.txt" files as input and
single step through the processing performed by the server.
The "--transport-command CMD" option on [/help?cmd=sync|fossil sync]
(and similar) causes the external program "CMD" to be used to move
the sync message to the server and retrieve the sync reply. The
CMD is given three arguments:
<ol>
<li> The URL of the server
<li> The name of a temporary file that contains the output-bound sync
protocol text, with the HTTP headers
<li> The name of a temporary file into which the CMD should write the
reply sync protocol text, again without any HTTP headers
</ol>
In a complex debugging situation, you can run the command
"fossil sync --transport-command ./debugging_script" where
"debugging_script" is some script of your own that invokes
the anomalous behavior you are trying to debug.

<title>A Technical Overview of Fossil's Design & Implementation</title>
<h2>1.0 Introduction</h2>
At its lowest level, a Fossil repository consists of an unordered set
of immutable "artifacts". You might think of these artifacts as "files",
since in many cases the artifacts are exactly that.
But other "structural artifacts" are also included in the mix.
These structural artifacts define the relationships
between artifacts - which files go together to form a particular
version of the project, who checked in that version and when, what was
the check-in comment, what wiki pages are included with the project, what
are the edit histories of each wiki page, what bug reports or tickets are
included, who contributed to the evolution of each ticket, and so forth.
This low-level file format is called the "global state" of
the repository, since this is the information that is synced to peer
repositories using push and pull operations. The low-level file format
is also called "enduring" since it is intended to last for many years.
The details of the low-level, enduring, global file format
are [./fileformat.wiki | described separately].
This article is about how Fossil is currently implemented. Instead of
dealing with vague abstractions of "enduring file formats" as the
[./fileformat.wiki | other document] does, this article provides
some detail on how Fossil actually stores information on disk.
<h2>2.0 Three Databases</h2>
Fossil stores state information in
[http://www.sqlite.org/ | SQLite] database files.
SQLite keeps an entire relational database, including multiple tables and
indices, in a single disk file. The SQLite library allows the database
files to be efficiently queried and updated using the industry-standard
SQL language. SQLite updates are atomic, so even in the event of
a system crashes or power failure the repository content is protected.
Fossil uses three separate classes of SQLite databases:
<ol>
<li>The configuration database
<li>Repository databases
<li>Checkout databases
</ol>
The configuration database is a one-per-user database that holds
global configuration information used by Fossil. There is one
repository database per project. The repository database is the
file that people are normally referring to when they say
"a Fossil repository". The checkout database is found in the working
checkout for a project and contains state information that is unique
to that working checkout.
Fossil does not always use all three database files. The web interface,
for example, typically only uses the repository database. And the
[/help/settings | fossil settings] command only opens the configuration database
when the --global option is used. But other commands use all three
databases at once. For example, the [/help/status | fossil status]
command will first locate the checkout database, then use the checkout
database to find the repository database, then open the configuration
database. Whenever multiple databases are used at the same time,
they are all opened on the same SQLite database connection using
SQLite's [http://www.sqlite.org/lang_attach.html | ATTACH] command.
The chart below provides a quick summary of how each of these
database files are used by Fossil, with detailed discussion following.

</ul></td>
</tr>
</table>
<h3 id="configdb">2.1 The Configuration Database</h3>
The configuration database holds cross-repository preferences and a list of all
repositories for a single user.
The [/help/settings | fossil settings] command can be used to specify various
operating parameters and preferences for Fossil repositories. Settings can
apply to a single repository, or they can apply globally to all repositories
for a user. If both a global and a repository value exists for a setting,
then the repository-specific value takes precedence. All of the settings
have reasonable defaults, and so many users will never need to change them.
But if changes to settings are desired, the configuration database provides
a way to change settings for all repositories with a single command, rather
than having to change the setting individually on each repository.
The configuration database also maintains a list of repositories. This
list is used by the [/help/all | fossil all] command in order to run various
operations such as "sync" or "rebuild" on all repositories managed by a user.
<h4 id="configloc">2.1.1 Location Of The Configuration Database</h4>
On Unix systems, the configuration database is named by the following
algorithm:
<table>
<tr><td>1. if environment variable FOSSIL_HOME exists
<td> → <td>$FOSSIL_HOME/.fossil
<tr><td>2. if file ~/.fossil exists
<td> →<td>~/.fossil
<tr><td>3. if environment variable XDG_CONFIG_HOME exists
<td> →<td>$XDG_CONFIG_HOME/fossil.db
<tr><td>4. if the directory ~/.config exists
<td> →<td>~/.config/fossil.db
<tr><td>5. Otherwise<td> →<td>~/.fossil
</table>
Another way of thinking of this algorithm is the following:
* Use "$FOSSIL_HOME/.fossil" if the FOSSIL_HOME variable is defined
* Use the XDG-compatible name (usually ~/.config/fossil.db) on XDG systems
if the ~/.fossil file does not already exist
* Otherwise, use the traditional unix name of "~/.fossil"
This algorithm is complex due to the need for historical compatibility.
Originally, the database was always just "~/.fossil". Then support
for the FOSSIL_HOME environment variable was added. Later, support for the
[https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html|XDG-compatible configation filenames]
was added. Each of these changes needed to continue to support legacy
installations.
On Windows, the configuration database is the first of the following
for which the corresponding environment variables exist:
* %FOSSIL_HOME%/_fossil
* %LOCALAPPDATA%/_fossil
* %APPDATA%/_fossil
* %USERPROFILES%/_fossil
* %HOMEDRIVE%%HOMEPATH%/_fossil
The second case is the one that usually determines the name. Note that the
FOSSIL_HOME environment variable can always be set to determine the
location of the configuration database. Note also that the configuration
database file itself is called ".fossil" or "fossil.db" on unix but
"_fossil" on windows.
The [/help?cmd=info|fossil info] command will show the location of
the configuration database on a line that starts with "config-db:".
<h3>2.2 Repository Databases</h3>
The repository database is the file that is commonly referred to as
"the repository". This is because the repository database contains,
among other things, the complete revision, ticket, and wiki history for
a project. It is customary to name the repository database after the
name of the project, with a ".fossil" suffix. For example, the repository
database for the self-hosting Fossil repository is called "fossil.fossil"
and the repository database for SQLite is called "sqlite.fossil".
<h4>2.2.1 Global Project State</h4>
The bulk of the repository database (typically 75 to 85%) consists
of the artifacts that comprise the
[./fileformat.wiki | enduring, global, shared state] of the project.
The artifacts are stored as BLOBs, compressed using
[http://www.zlib.net/ | zlib compression] and, where applicable,
using [./delta_encoder_algorithm.wiki | delta compression].
The combination of zlib and delta compression results in a considerable
space savings. For the SQLite project (when this paragraph was last
updated on 2020-02-08)
the total size of all artifacts is over 7.1 GB but thanks to the
combined zlib and delta compression, that content only takes less than
97 MB of space in the repository database, for a compression ratio
of about 74:1. The median size of all content BLOBs after delta
and zlib compression have been applied is 156 bytes.
The median size of BLOBs without compression is 45,312 bytes.
Note that the zlib and delta compression is not an inherent part of the
Fossil file format; it is just an optimization.
The enduring file format for Fossil is the unordered
set of artifacts. The compression techniques are just a detail of
how the current implementation of Fossil happens to store these artifacts
efficiently on disk.
All of the original uncompressed and un-delta'd artifacts can be extracted
from a Fossil repository database using
the [/help/deconstruct | fossil deconstruct]
command. Individual artifacts can be extracted using the
[/help/artifact | fossil artifact] command.
When accessing the repository database using raw SQL and the
[/help/sqlite3 | fossil sql] command, the extension function
"<tt>content()</tt>" with a single argument which is the SHA1 or
SHA3-256 hash
of an artifact will return the complete uncompressed
content of that artifact.
Going the other way, the [/help/reconstruct | fossil reconstruct]
command will scan a directory hierarchy and add all files found to
a new repository database. The [/help/import | fossil import] command
works by reading the input git-fast-export stream and using it to construct
corresponding artifacts which are then written into the repository database.
<h4>2.2.2 Project Metadata</h4>
The global project state information in the repository database is
supplemented by computed metadata that makes querying the project state
more efficient. Metadata includes information such as the following:
* The names for all files found in any check-in.
* All check-ins that modify a given file
* Parents and children of each check-in.
* Potential timeline rows.
* The names of all symbolic tags and the check-ins they apply to.
* The names of all wiki pages and the artifacts that comprise each
wiki page.
* Attachments and the wiki pages or tickets they apply to.
* Current content of each ticket.
* Cross-references between tickets, check-ins, and wiki pages.
The metadata is held in various SQL tables in the repository database.
The metadata is designed to facilitate queries for the various timelines and
reports that Fossil generates.
As the functionality of Fossil evolves,
the schema for the metadata can and does change.
But schema changes do not invalidate the repository. Remember that the
metadata contains no new information - only information that has been
extracted from the canonical artifacts and saved in a more useful form.
Hence, when the metadata schema changes, the prior metadata can be discarded
and the entire metadata corpus can be recomputed from the canonical
artifacts. That is what the
[/help/rebuild | fossil rebuild] command does.
<h4>2.2.3 Display And Processing Preferences</h4>
The repository database also holds information used to help format
the display of web pages and configuration settings that override the
global configuration settings for the specific repository. All of
this information (and the user credentials and privileges too) is
local to each repository database; it is not shared between repositories
by [/help/sync | fossil sync]. That is because it is entirely reasonable
that two different websites for the same project might have completely
different display preferences and user communities. One instance of the
project might be a fork of the other, for example, which pulls from the
other but never pushes and extends the project in ways that the keepers of
the other website disapprove of.
Display and processing information includes the following:
* The name and description of the project
* The CSS file, header, and footer used by all web pages
* The project logo image
* Fields of tickets that are considered "significant" and which are
therefore collected from artifacts and made available for display
* Templates for screens to view, edit, and create tickets
* Ticket report formats and display preferences
* Local values for [/help/settings | settings] that override the
global values defined in the per-user configuration database.
Though the display and processing preferences do not move between
repository instances using [/help/sync | fossil sync], this information
can be shared between repositories using the
[/help/config | fossil config push] and
[/help/config | fossil config pull] commands.
The display and processing information is also copied into new
repositories when they are created using
[/help/clone | fossil clone].
<h4>2.2.4 User Credentials And Privileges</h4>
Just because two development teams are collaborating on a project and allow
push and/or pull between their repositories does not mean that they
trust each other enough to share passwords and access privileges.
Hence the names and emails and passwords and privileges of users are
considered private information that is kept locally in each repository.
Each repository database has a table holding the username, privileges,
and login credentials for users authorized to interact with that particular
database. In addition, there is a table named "concealed" that maps the
SHA1 hash of each users email address back into their true email address.
The concealed table allows just the SHA1 hash of email addresses to
be stored in tickets, and thus prevents actual email addresses from falling
into the hands of spammers who happen to clone the repository.
The content of the user and concealed tables can be pushed and pulled using the
[/help/config | fossil config push] and
[/help/config | fossil config pull] commands with the "user" and
"email" as the AREA argument, but only if you have administrative
privileges on the remote repository.
<h4>2.2.5 Shunned Artifact List</h4>
The set of canonical artifacts for a project - the global state for the
project - is intended to be an append-only database. In other words,
new artifacts can be added but artifacts can never be removed. But
it sometimes happens that inappropriate content is mistakenly or
maliciously added to a repository. The only way to get rid of
the undesired content is to [./shunning.wiki | "shun"] it.
The "shun" table in the repository database records the hash values for
all shunned artifacts.
The shun table can be pushed or pulled using
the [/help/config | fossil config] command with the "shun" AREA argument.
The shun table is also copied during a [/help/clone | clone].
<h3 id="localdb">2.3 Checkout Databases</h3>
Fossil allows a single repository
to have multiple working checkouts. Each working checkout has a single
database in its root directory that records the state of that checkout.
The checkout database is named "_FOSSIL_" or ".fslckout".
The checkout database records information such as the following:
* The name of the repository database file.
* The version that is currently checked out.
* Files that have been [/help/add | added],
[/help/rm | removed], or [/help/mv | renamed] but not
yet committed.
* The mtime and size of files as they were originally checked out,
in order to expedite checking which files have been edited.
* Other check-ins that have been [/help/merge | merged] into the
working checkout but not yet committed.
* Copies of files prior to the most recent undoable operation - needed to
implement the [/help/undo | undo] and [/help/redo | redo] commands.
* The [/help/stash | stash].
* State information for the [/help/bisect | bisect] command.
For Fossil commands that run from within a working checkout, the
first thing that happens is that Fossil locates the checkout database.
Fossil first looks in the current directory. If not found there, it
looks in the parent directory. If not found there, the parent of the
parent. And so forth until either the checkout database is found
or the search reaches the root of the file system. (In the latter case,
Fossil returns an error, of course.) Once the checkout database is
located, it is used to locate the repository database.
Notice that the checkout database contains a pointer to the repository
database but that the repository database has no record of the checkout
databases. That means that a working checkout directory tree can be
freely renamed or copied or deleted without consequence. But the
repository database file, on the other hand, has to stay in the same
place with the same name or else the open checkout databases will not
be able to find it.
A checkout database is created by the [/help/open | fossil open] command.
A checkout database is deleted by [/help/close | fossil close]. The
fossil close command really isn't needed; one can accomplish the same
thing simply by deleting the checkout database.
Note that the stash, the undo stack, and the state of the bisect command
are all contained within the checkout database. That means that the
fossil close command will delete all stash content, the undo stack, and
the bisect state. The close command is not undoable. Use it with care.

TH1 Hooks
=========
<big><big><big><font color="red">** DRAFT **</font></big></big></big>
The **TH1 hooks** feature allows <a href="th1.md">TH1</a> scripts to be
configured that can monitor, create, alter, or cancel the execution of
Fossil commands and web pages.
This feature requires the TH1 hooks feature to be enabled at compile-time.
Additionally, the "th1-hooks" repository setting must be enabled at runtime
in order to successfully make use of this feature.
TH1 Hook Related User-Defined Procedures
----------------------------------------
In order to activate TH1 hooks, one or more of the following user-defined
procedures should be defined, generally from within the "th1-setup" script
(setting) for a repository. The following bullets summarize the available
TH1 hooks:
* command\_hook -- _Called before execution of a command._
* command\_notify -- _Called after execution of a command._
* webpage\_hook -- _Called before rendering of a web page._
* webpage\_notify -- _Called after rendering of a web page._
TH1 Hook Related Variables for Commands
---------------------------------------
* cmd\_name -- _Name of command being executed._
* cmd\_args -- _Current command line arguments._
* cmd\_flags -- _Bitmask of CMDFLAG values for the command being executed._
TH1 Hook Related Variables for Web Pages
----------------------------------------
* web\_name -- _Name of web page being rendered._
* web\_args -- _Current web page arguments._
* web\_flags -- _Bitmask of CMDFLAG values for the web page being rendered._
<a id="cmdReturnCodes"></a>TH1 Hook Related Return Codes for Commands
-----------------------------------------------------------------------
* TH\_OK -- _Command will be executed, notification will be executed._
* TH\_ERROR -- _Command will be skipped, notification will be skipped,
error message will be emitted._
* TH\_BREAK -- _Command will be skipped, notification will be skipped._
* TH\_RETURN -- _Command will be executed, notification will be skipped._
* TH\_CONTINUE -- _Command will be skipped, notification will be executed._
For commands that are not included in the Fossil binary, allowing their
execution will cause the standard "unknown command" error message to be
generated, which will typically exit the process. Therefore, adding a
new command generally requires using the TH_CONTINUE return code.
<a id="webReturnCodes"></a>TH1 Hook Related Return Codes for Web Pages
------------------------------------------------------------------------
* TH\_OK -- _Web page will be rendered, notification will be executed._
* TH\_ERROR -- _Web page will be skipped, notification will be skipped,
error message will be emitted._
* TH\_BREAK -- _Web page will be skipped, notification will be skipped._
* TH\_RETURN -- _Web page will be rendered, notification will be skipped._
* TH\_CONTINUE -- _Web page will be skipped, notification will be executed._
For web pages that are not included in the Fossil binary, allowing their
rendering will cause the standard "Not Found" error message to be generated,
which will cause an HTTP 404 status code to be sent. Therefore, adding a
new web page generally requires using the TH_CONTINUE return code.
<a id="triggerReturnCodes"></a>Triggering TH1 Return Codes from a Script
--------------------------------------------------------------------------
* TH\_OK -- _This is the default return code, nothing special needed._
* TH\_ERROR -- _Use the **error** command._
* TH\_BREAK -- _Use the **break** command._
* TH\_RETURN -- _Use the **return -code 5** command._
* TH\_CONTINUE -- _Use the **continue** command._
<a id="command_hook"></a>TH1 command_hook Procedure
-----------------------------------------------------
* command\_hook
This user-defined procedure, if present, is called just before the
execution of a command. The name of the command being executed will
be stored in the "cmd\_name" global variable. The arguments to the
command being executed will be stored in the "cmd\_args" global variable.
The associated CMDFLAG value will be stored in the "cmd\_flags" global
variable. Before exiting, the procedure should trigger the return
<a href="#cmdReturnCodes">code</a> that corresponds to the desired action
to take next.
<a id="command_notify"></a>TH1 command_notify Procedure
---------------------------------------------------------
* command\_notify
This user-defined procedure, if present, is called just after the
execution of a command. The name of the command being executed will
be stored in the "cmd\_name" global variable. The arguments to the
command being executed will be stored in the "cmd\_args" global variable.
The associated CMDFLAG value will be stored in the "cmd\_flags" global
variable. Before exiting, the procedure should trigger the return
<a href="#cmdReturnCodes">code</a> that corresponds to the desired action
to take next.
<a id="webpage_hook"></a>TH1 webpage_hook Procedure
-----------------------------------------------------
* webpage\_hook
This user-defined procedure, if present, is called just before the
rendering of a web page. The name of the web page being rendered will
be stored in the "web\_name" global variable. The arguments to the
web page being rendered will be stored in the "web\_args" global variable.
The associated CMDFLAG value will be stored in the "web\_flags" global
variable. Before exiting, the procedure should trigger the return
<a href="#webReturnCodes">code</a> that corresponds to the desired action
to take next.
<a id="webpage_notify"></a>TH1 webpage_notify Procedure
---------------------------------------------------------
* webpage\_notify
This user-defined procedure, if present, is called just after the
rendering of a web page. The name of the web page being rendered will
be stored in the "web\_name" global variable. The arguments to the
web page being rendered will be stored in the "web\_args" global variable.
The associated CMDFLAG value will be stored in the "web\_flags" global
variable. Before exiting, the procedure should trigger the return
<a href="#webReturnCodes">code</a> that corresponds to the desired action
to take next.

TH1 Scripts
===========
TH1 is a very small scripting language used to help generate web-page
content in Fossil.
Origins
-------
TH1 began as a minimalist re-implementation of the Tcl scripting language.
There was a need to test the SQLite library on Symbian phones, but at that
time all of the test cases for SQLite were written in Tcl and Tcl could not
be easily compiled on the SymbianOS. So TH1 was developed as a cut-down
version of Tcl that would facilitate running the SQLite test scripts on
SymbianOS.
Fossil was first being designed at about the same time that TH1 was
being developed for testing SQLite on SymbianOS.
Early prototypes of Fossil were written in pure Tcl. But as the development
shifted toward the use of C-code, the need arose to have a Tcl-like
scripting language to help with code generation. TH1 was small and
light-weight and used minimal resources and seemed ideally suited for the
task.
The name "TH1" stands "Test Harness 1", since that was its original purpose.
Overview
--------
TH1 is a string-processing language. All values are strings. Any numerical
operations are accomplished by converting from string to numeric, performing
the computation, then converting the result back into a string. (This might
seem inefficient, but it is faster than people imagine, and numeric
computations do not come up very often for the kinds of work that TH1 does,
so it has never been a factor.)
A TH1 script consists of a sequence of commands.
Each command is terminated by the first *unescaped* newline or ";" character.
The text of the command (excluding the newline or semicolon terminator)
is broken into space-separated tokens. The first token is the command
name and subsequent tokens are the arguments. In this sense, TH1 syntax
is similar to the familiar command-line shell syntax.
A token is any sequence of characters other than whitespace and semicolons.
Text inside double-quotes is a single token even if it includes
whitespace and semicolons. Text within {...} pairs is also a
single token, which is useful because curly braces are easier to “pairâ€
and nest properly than double-quotes.
The nested {...} form of tokens is important because it allows TH1 commands
to have an appearance similar to C/C++. It is important to remember, though,
that a TH1 script is really just a list of text commands, not a context-free
language with a grammar like C/C++. This can be confusing to long-time
C/C++ programmers because TH1 does look a lot like C/C++, but the semantics
of TH1 are closer to FORTH or Lisp than they are to C.
Consider the `if` command in TH1.
if {$current eq "dev"} {
puts "hello"
} else {
puts "world"
}
The example above is a single command. The first token, and the name
of the command, is `if`.
The second token is `$current eq "dev"` - an expression. (The outer {...}
are removed from each token by the command parser.) The third token
is the `puts "hello"`, with its whitespace and newlines. The fourth token
is `else` and the fifth and last token is `puts "world"`.
The `if` command evaluates its first argument (the second token)
as an expression, and if that expression is true, evaluates its
second argument (the third token) as a TH1 script.
If the expression is false and the third argument is `else`, then
the fourth argument is evaluated as a TH1 expression.
So, you see, even though the example above spans five lines, it is really
just a single command.
All of this also explains the emphasis on *unescaped* characters above:
the curly braces `{ }` are string quoting characters in Tcl/TH1, not
block delimiters as in C. This is how we can have a command that extends
over multiple lines. It is also why the `else` keyword must be cuddled
up with the closing brace for the `if` clause's scriptlet. The following
is invalid Tcl/TH1:
if {$current eq "dev"} {
puts "hello"
}
else {
puts "world"
}
If you try to run this under either Tcl or TH1, the interpreter will
tell you that there is no `else` command, because with the newline on
the third line, you terminated the `if` command.
Occasionally in Tcl/TH1 scripts, you may need to use a backslash at the
end of a line to allow a command to extend over multiple lines without
being considered two separate commands. Here's an example from one of
Fossil's test scripts:
return [lindex [regexp -line -inline -nocase -- \
{^uuid:\s+([0-9A-F]{40}) } [eval [getFossilCommand \
$repository "" info trunk]]] end]
Those backslashes allow the command to wrap nicely within a standard
terminal width while telling the interpreter to consider those three
lines as a single command.
Summary of Core TH1 Commands
----------------------------
The original Tcl language (after which TH1 is modeled) has a very rich
repertoire of commands. TH1, as it is designed to be minimalist and
embedded has a greatly reduced command set. The following bullets
summarize the commands available in TH1:
* array exists VARNAME
* array names VARNAME
* break
* catch SCRIPT ?VARIABLE?
* continue
* error ?STRING?
* expr EXPR
* for INIT-SCRIPT TEST-EXPR NEXT-SCRIPT BODY-SCRIPT
* foreach VARIABLE-LIST VALUE-LIST BODY-SCRIPT
* if EXPR SCRIPT (elseif EXPR SCRIPT)* ?else SCRIPT?
* info commands
* info exists VARNAME
* info vars
* lappend VARIABLE TERM ...
* lindex LIST INDEX
* list ARG ...
* llength LIST
* lsearch LIST STRING
* proc NAME ARG-LIST BODY-SCRIPT
* rename OLD NEW
* return ?-code CODE? ?VALUE?
* set VARNAME VALUE
* string compare STR1 STR2
* string first NEEDLE HAYSTACK ?START-INDEX?
* string index STRING INDEX
* string is CLASS STRING
* string last NEEDLE HAYSTACK ?START-INDEX?
* string match PATTERN STRING
* string length STRING
* string range STRING FIRST LAST
* string repeat STRING COUNT
* unset VARNAME
* uplevel ?LEVEL? SCRIPT
* upvar ?FRAME? OTHERVAR MYVAR ?OTHERVAR MYVAR?
All of the above commands work as in the original Tcl. Refer to the
<a href="https://www.tcl-lang.org/man/tcl/contents.htm">Tcl documentation</a>
for details.
Summary of Core TH1 Variables
-----------------------------
* tcl\_platform(engine) -- _This will always have the value "TH1"._
* tcl\_platform(platform) -- _This will have the value "windows" or "unix"._
* th\_stack\_trace -- _This will contain error stack information._

Each of the commands above is documented by a block comment above their
implementation in the th\_main.c or th\_tcl.c source files.
All commands starting with "tcl", with the exception of "tclReady",
require the Tcl integration subsystem be included at compile-time.
Additionally, the "tcl" repository setting must be enabled at runtime
in order to successfully make use of these commands.
<a id="anoncap"></a>TH1 anoncap Command
-----------------------------------------
Deprecated: prefer [capexpr](#capexpr) instead.
* anoncap STRING...
Returns true if the anonymous user has all of the capabilities listed
in STRING.
<a id="anycap"></a>TH1 anycap Command
---------------------------------------
Deprecated: prefer [capexpr](#capexpr) instead.
* anycap STRING
Returns true if the current user user has any one of the capabilities
listed in STRING.
<a id="artifact"></a>TH1 artifact Command
-------------------------------------------
* artifact ID ?FILENAME?
Attempts to locate the specified artifact and return its contents. An
error is generated if the repository is not open or the artifact cannot
be found.
<a id="bireqjs"></a>TH1 builtin_request_js Command
--------------------------------------------------
* builtin_request_js NAME
NAME must be the name of one of the
[built-in javascript source files](/dir?ci=trunk&type=flat&name=src&re=js$).
This command causes that javascript file to be appended to the delivered
document.
<a id="capexpr"></a>TH1 capexpr Command
-----------------------------------------------------
* capexpr CAPABILITY-EXPR
The capability expression is a list. Each term of the list is a
cluster of [capability letters](./caps/ref.html).
The overall expression is true if any
one term is true. A single term is true if all letters within that
term are true. Or, if the term begins with "!", then the term is true
if none of the terms are true. Or, if the term begins with "@" then
the term is true if all of the capability letters in that term are
available to the "anonymous" user. Or, if the term is "*" then it is
always true.
Examples:
```
capexpr {j o r} True if any one of j, o, or r are available
capexpr {oh} True if both o and h are available
capexpr {@2 @3 4 5 6} 2 or 3 available for anonymous or one of
4, 5 or 6 is available for the user
capexpr L True if the user is logged in
capexpr !L True if the user is not logged in
```
The `L` pseudo-capability is intended only to be used on its own or with
the `!` prefix for implementing login/logout menus via the `mainmenu`
site configuration option:
```
Login /login !L {}
Logout /logout L {}
```
i.e. if the user is logged in, show the "Logout" link, else show the
"Login" link.
<a id="captureTh1"></a>TH1 captureTh1 Command
-----------------------------------------------------
* captureTh1 STRING
Executes its single argument as TH1 code and captures any
TH1-generated output as a string, which becomes the result of the
function call. e.g. any `puts` calls made from that block will not
generate any output, and instead their output will become part of the
result string.
<a id="cgiHeaderLine"></a>TH1 cgiHeaderLine Command
-----------------------------------------------------
* cgiHeaderLine line
Adds the specified line to the CGI header.
<a id="checkout"></a>TH1 checkout Command
-------------------------------------------
* checkout ?BOOLEAN?
Return the fully qualified directory name of the current checkout or an
empty string if it is not available. Optionally, it will attempt to find
the current checkout, opening the configuration ("user") database and the
repository as necessary, if the boolean argument is non-zero.
<a id="combobox"></a>TH1 combobox Command
-------------------------------------------
* combobox NAME TEXT-LIST NUMLINES
Generates and emits an HTML combobox. NAME is both the name of the
CGI parameter and the name of a variable that contains the currently
selected value. TEXT-LIST is a list of possible values for the
combobox. NUMLINES is 1 for a true combobox. If NUMLINES is greater
than one then the display is a listbox with the number of lines given.
<a id="copybtn"></a>TH1 copybtn Command
-----------------------------------------
* copybtn TARGETID FLIPPED TEXT ?COPYLENGTH?
Output TEXT with a click-to-copy button next to it. Loads the copybtn.js
Javascript module, and generates HTML elements with the following IDs:
* TARGETID: The `<span>` wrapper around TEXT.
* copy-TARGETID: The `<span>` for the copy button.
If the FLIPPED argument is non-zero, the copy button is displayed after TEXT.
The optional COPYLENGTH argument defines the length of the substring of TEXT
copied to clipboard:
* <= 0: No limit (default if the argument is omitted).
* >= 3: Truncate TEXT after COPYLENGTH (single-byte) characters.
* 1: Use the "hash-digits" setting as the limit.
* 2: Use the length appropriate for URLs as the limit (defined at
compile-time by `FOSSIL_HASH_DIGITS_URL`, defaults to 16).
<a id="date"></a>TH1 date Command
-----------------------------------
* date ?-local?
Return a string which is the current time and date. If the -local
option is used, the date appears using localtime instead of UTC.
<a id="decorate"></a>TH1 decorate Command
-------------------------------------------
* decorate STRING
Renders STRING as wiki content; however, only links are handled. No
other markup is processed.
<a id="defHeader"></a>TH1 defHeader Command
---------------------------------------------
* defHeader
Returns the default page header.
<a id="dir"></a>TH1 dir Command
---------------------------------
* dir CHECKIN ?GLOB? ?DETAILS?
Returns a list containing all files in CHECKIN. If GLOB is given only
the files matching the pattern GLOB within CHECKIN will be returned.
If DETAILS is non-zero, the result will be a list-of-lists, with each
element containing at least three elements: the file name, the file
size (in bytes), and the file last modification time (relative to the
time zone configured for the repository).
<a id="enable_htmlify"></a>TH1 enable\_htmlify Command
------------------------------------------------------
* enable\_htmlify
* enable\_htmlify ?TRACE-LABEL? BOOLEAN
By default, certain output from `puts` and similar commands is escaped
for HTML. The first call form returns the current state of that
feature: `1` for on and `0` for off. The second call form enables
(non-0) or disables (0) that feature and returns the *pre-call* state
of that feature (so that a second call can pass that value to restore
it to its previous state). The optional `TRACE-LABEL` argument causes
the TH1 tracing output (if enabled) to add a marker when the second
form of this command is invoked, and includes that label and the
boolean argument's value in the trace. If tracing is disabled, that
argument has no effect.
<a id="enable_output"></a>TH1 enable\_output Command
------------------------------------------------------
* enable\_output BOOLEAN
Enable or disable sending output when the combobox, copybtn, puts, or wiki
commands are used.
<a id="encode64"></a>TH1 encode64 Command

default value when there is no matching query parameter.
<a id="glob_match"></a>TH1 glob\_match Command
------------------------------------------------
* glob\_match ?-one? ?--? patternList string
Checks the string against the specified glob pattern -OR- list of glob
patterns and returns non-zero if there is a match.
<a id="globalState"></a>TH1 globalState Command
-------------------------------------------------
* globalState NAME ?DEFAULT?
Returns a string containing the value of the specified global state
variable -OR- the specified default value. The supported items are:
1. **checkout** -- _Active local checkout directory, if any._

1. **vfs** -- _SQLite VFS in use, if overridden._
Attempts to query for unsupported global state variables will result
in a script error. Additional global state variables may be exposed
in the future.
<a id="hascap"></a>TH1 hascap Command

1. **see** -- _Uses the SQLite Encryption Extension._
Specifying an unknown feature will return a value of false, it will not
raise a script error.
<a id="html"></a>TH1 html Command
-----------------------------------
* html STRING
Outputs the STRING escaped for HTML.
<a id="htmlize"></a>TH1 htmlize Command
-----------------------------------------
* htmlize STRING

* http ?-asynchronous? ?--? url ?payload?
Performs an HTTP or HTTPS request for the specified URL. If a
payload is present, it will be interpreted as text/plain and
the POST method will be used; otherwise, the GET method will
be used. Upon success, if the -asynchronous option is used, an
empty string is returned as the result; otherwise, the response
from the server is returned as the result. Synchronous requests
are not currently implemented.
<a id="httpize"></a>TH1 httpize Command
-----------------------------------------
* httpize STRING
Escape all characters of STRING which have special meaning in URI
components. Returns the escaped string.
<a id="insertCsrf"></a>TH1 insertCsrf Command

While rendering a form, call this command to add the Anti-CSRF token
as a hidden element of the form.
<a id="linecount"></a>TH1 linecount Command
---------------------------------------------
* linecount STRING MAX MIN
Returns one more than the number of `\n` characters in STRING. But
never returns less than MIN or more than MAX.
<a id="markdown"></a>TH1 markdown Command
-------------------------------------------
* markdown STRING
Renders the input string as markdown. The result is a two-element list.
The first element contains the body, rendered as HTML. The second element
is the text-only title string.
<a id="nonce"></a>TH1 nonce Command
-------------------------------------
* nonce
Returns the value of the cryptographic nonce for the request being processed.
<a id="puts"></a>TH1 puts Command
-----------------------------------
* puts STRING
Outputs the STRING unchanged, where "unchanged" might, depending on
the context, mean "with some characters escaped for HTML."
<a id="query"></a>TH1 query Command
-------------------------------------
* query ?-nocomplain? SQL CODE
Runs the SQL query given by the SQL argument. For each row in the result
set, run CODE.
In SQL, parameters such as $var are filled in using the value of variable
"var". Result values are stored in variables with the column name prior
to each invocation of CODE.
<a id="randhex"></a>TH1 randhex Command
-----------------------------------------
* randhex N
Returns a string of N*2 random hexadecimal digits with N<50. If N is
omitted, use a value of 10.
<a id="redirect"></a>TH1 redirect Command
-------------------------------------------
* redirect URL ?withMethod?
Issues an HTTP redirect to the specified URL and then exits the process.
By default, an HTTP status code of 302 is used. If the optional withMethod
argument is present and non-zero, an HTTP status code of 307 is used, which
should force the user agent to preserve the original method for the request
(e.g. GET, POST) instead of (possibly) forcing the user agent to change the
method to GET.
<a id="regexp"></a>TH1 regexp Command
---------------------------------------
* regexp ?-nocase? ?--? exp string
Checks the string against the specified regular expression and returns
non-zero if it matches. If the regular expression is invalid or cannot
be compiled, an error will be generated.
<a id="reinitialize"></a>TH1 reinitialize Command
---------------------------------------------------
* reinitialize ?FLAGS?
Reinitializes the TH1 interpreter using the specified flags.
<a id="render"></a>TH1 render Command
---------------------------------------
* render STRING
Renders the TH1 template and writes the results.
<a id="repository"></a>TH1 repository Command
-----------------------------------------------
* repository ?BOOLEAN?
Returns the fully qualified file name of the open repository or an empty
string if one is not currently open. Optionally, it will attempt to open
the repository if the boolean argument is non-zero.
<a id="searchable"></a>TH1 searchable Command
-----------------------------------------------
* searchable STRING...
Return true if searching in any of the document classes identified
by STRING is enabled for the repository and user has the necessary
capabilities to perform the search. The possible document classes
are:
1. **c** -- _Check-in comments_
1. **d** -- _Embedded documentation_
1. **t** -- _Tickets_
1. **w** -- _Wiki_
To be clear, only one of the document classes identified by each STRING
needs to be searchable in order for that argument to be true. But all
arguments must be true for this routine to return true. Hence, to see
if ALL document classes are searchable:
if {[searchable c d t w]} {...}
But to see if ANY document class is searchable:
if {[searchable cdtw]} {...}
This command is useful for enabling or disabling a "Search" entry on the
menu bar.

Why is Fossil based on SQLite instead of a distributed NoSQL database? 2. Why is Fossil written in C instead of a modern high-level language? Neither question can be answered directly because they are both based on false assumptions. We claim that Fossil is not based on SQLite at all and that Fossil is not based on a distributed NoSQL database because Fossil is a distributed NoSQL database. And, Fossil does use a modern high-level language for its implementation, namely SQL. <h2>Fossil Is A NoSQL Database</h2> We begin with the first question: Fossil is not based on a distributed NoSQL database because Fossil <u><i>is</i></u> a distributed NoSQL database. Fossil is <u>not</u> based on SQLite. The current implementation of Fossil uses SQLite as a local store for the content of the distributed database and as a cache for meta-information about the distributed database that is precomputed for quick and easy presentation. But the use of SQLite in this role is an implementation detail and is not fundamental to the design. Some future version of Fossil might do away with SQLite and substitute a pile-of-files or a key/value database in place of SQLite. (Actually, that is very unlikely to happen since SQLite works amazingly well in its current role, but the point is that omitting SQLite from Fossil is a theoretical possibility.) The underlying database that Fossil implements has nothing to do with SQLite, or SQL, or even relational database theory. The underlying database is very simple: it is an unordered collection of "artifacts". An artifact is a list of bytes - a "file" in the usual manner of thinking. Many artifacts are simply the content of source files that have been checked into the Fossil repository. Call these "content artifacts". Other artifacts, known as "control artifacts", contain ASCII text in a particular format that defines relationships between other artifacts, such as which content artifacts that go together to form a particular version of the project. Each artifact is named by its SHA1 or SHA3-256 hash and is thus immutable. Artifacts can be added to the database but not removed (if we ignore the exceptional case of [./shunning.wiki | shunning].) Repositories synchronize by computing the union of their artifact sets. SQL and relation theory play no role in any of this. SQL enters the picture only in the implementation details. The current implementation of Fossil stores each artifact as a BLOB in an SQLite |

There is the bag-of-artifacts database which is non-relational and distributed (like a NoSQL database) and there is the local relational database. The bag-of-artifacts database has a fixed format and is what defines a Fossil repository. Fossil will never modify the file format of the bag-of-artifacts database in an incompatible way because to do so would be to make something that is no longer "Fossil".

There is the bag-of-artifacts database which is non-relational and distributed (like a NoSQL database) and there is the local relational database. The bag-of-artifacts database has a fixed format and is what defines a Fossil repository. Fossil will never modify the file format of the bag-of-artifacts database in an incompatible way because to do so would be to make something that is no longer "Fossil". The local relational database, on the other hand, is a cache that contains information derived from the bag-of-artifacts. The schema of the local relational database changes from time to time as the Fossil implementation is enhanced, and the content is recomputed from the unchanging bag of artifacts. The local relational database is an implementation detail which currently happens to use SQLite. Another way to think of the relational tables in a Fossil repository is as an index for the artifacts. Without the relational tables, to generate a report like a timeline would require scanning every artifact - the equivalent of a full table scan. The relational tables hold pointers to the relevant artifacts in presorted order so that generating a timeline is much more efficient. So like an index in a relational database, the relational tables in a Fossil repository do not add any new information, they merely make the information in the artifacts faster and easier to look up. Fossil is not "based" on SQLite. Fossil simply exploits SQLite as a powerful tool to make the implementation easier. And Fossil doesn't use a distributed NoSQL database because Fossil is a distributed NoSQL database. That answers the first question. <h2>SQL Is A High-Level Scripting Language</h2> The second concern states that Fossil does not use a high-level scripting language. But that is not true. Fossil uses SQL (as implemented by SQLite) as its scripting language. This misunderstanding likely arises because people fail to appreciate that SQL is a programming language. People are taught that SQL is a "query language" as if that were somehow different from a "programming language". But they really are two different flavors of the same thing. I find that people do better with SQL if they think of SQL as a programming language and each statement of SQL is a separate program. SQL is a peculiar programming language in that one uses SQL to specify <i>what</i> to compute whereas in most other programming languages one specifies <i>how</i> to carry out the computation. This difference means that SQL is an extraordinary high-level programming language, but it is still just a programming language. For certain types of problems, SQL has a huge advantage over other programming languages because it is so high level and because it allows programmers to focus more on the <i>what</i> and less on the <i>how</i> of a computation. In other words, programmers tend to think about problems at a much higher level when using SQL; this can result in better applications. SQL is also very dense. In practice, this often means that a few lines of SQL can often replace hundreds or thousands of lines of procedural code, with a corresponding decrease in programming effort and opportunities to introduce bugs. Fossil happens to be one of those problems for which SQL is well suited. Much of the "heavy lifting" within the Fossil implementation is carried out using SQL statements. It is true that these SQL statements are glued together with C code, but it turns out that C works surprisingly well in that role. Several early prototypes of Fossil were written in a scripting language (TCL). We normally find that TCL programs are shorter than the equivalent C code by a factor of 10 or more. But in the case of Fossil, the use of TCL was actually making the code longer and more difficult to understand. And so in the final design, we switched from TCL to C in order to make the code easier to implement and debug. Without the advantages of having SQLite built in, the design might well have followed a different path. Most reports generated by Fossil involve a complex set of queries against the relational tables of the repository database. These queries are normally implemented in only a few dozen lines of SQL code. But if those queries had been implemented procedurally using a key/value or pile-of-files database, it may have well been the case that a high-level scripting language such as Tcl, Python, or Ruby may have worked out better than C. |

Each ticket change artifact corresponds to a single change to a ticket. The act of creating a ticket is considered a change. Each ticket change artifact contains the following information: <ul> <li>The ID of the ticket that was changed <li>The time stamp for when the change occurred <li>The user who made the change <li>A list of key/value pairs that show what changed in the ticket </ul> To determine the current state of a particular ticket, Fossil orders the change artifacts for that ticket from oldest to most recent, then applies each change in time stamp order. On each change artifact, there are one or more key/value pairs that implement the change. The key corresponds to a field of the ticket that is modified. The value may either replace the earlier value for that key, or the value may be appended to the prior value. <h2>2.0 Ticket Tables</h2> The low-level artifact format for ticket content is tedious and cumbersome to access in real time. To facilitate reporting and display of tickets, the low-level artifact information is collected and summarized in a pair of SQL tables in each local repository. Display and reporting of tickets is accomplished by querying these two tables. Note that only the low-level ticket change artifacts are synced. The content of the two ticket tables can always be reconstructed from the ticket change artifacts. And, indeed, the reconstruction of the ticket tables from low-level artifacts happens automatically whenever new ticket change artifacts are received by the system. The important point to remember is that display of tickets is accomplished using SQL tables but that recording and syncing of ticket information is accomplished using ticket change artifacts. <h3>2.1 Ticket Table Schema</h3> The two ticket tables are called TICKET and TICKETCHNG. The default schema (as of this writing) for these two tables is shown below: <verbatim> CREATE TABLE ticket( -- Do not change any column that begins with tkt_ tkt_id INTEGER PRIMARY KEY, tkt_uuid TEXT UNIQUE, tkt_mtime DATE, tkt_ctime DATE, -- Add as many fields as required below this line type TEXT, status TEXT, subsystem TEXT, priority TEXT, severity TEXT, foundin TEXT, private_contact TEXT, resolution TEXT, title TEXT, comment TEXT ); CREATE TABLE ticketchng( -- Do not change any column that begins with tkt_ tkt_id INTEGER REFERENCES ticket, tkt_rid INTEGER REFERENCES blob, tkt_mtime DATE, -- Add as many fields as required below this line login TEXT, username TEXT, mimetype TEXT, icomment TEXT ); CREATE INDEX ticketchng_idx1 ON ticketchng(tkt_id, tkt_mtime); </verbatim> Generally speaking, there is one row in the TICKETCHNG table for each change to each ticket. In other words, there is one row in the TICKETCHNG table for each low-level ticket change artifact. The TICKET table, on the other hand, contains a summary of the current status of each ticket. Fields of the TICKET and TICKETCHNG tables that begin with "tkt_" are used internally by Fossil. The logic inside of Fossil that converts ticket change artifacts into row data for the two ticket tables expects the "tkt_" fields to always be present. All of the other fields of the TICKET and TICKETCHNG tables are "user defined" in the sense that they can be anything the administrator of the system wants them to be. The user-defined fields should correspond to keys in the key/value pairs of the ticket change artifacts. The <b>tkt_id</b> fields of TICKET and TICKETCHNG are an integer key used to uniquely identify the ticket to which the row belongs. These keys are for internal use only and may change when doing a "fossil rebuild". The <b>tkt_uuid</b> field is the unique hexadecimal identifier for the ticket. Ticket identifiers appear to be SHA1 hash strings, but they are not really the hash of any identifiable artifact. They are just random hexadecimal numbers. When creating a new ticket, Fossil uses a (high-quality) pseudo-random number generator to create the ticket number. The ticket numbers are large so that the chance of collision between any two tickets is vanishingly small. The <b>tkt_mtime</b> field of TICKET shows the time (as a Julian day number) of the most recent ticket change artifact for that ticket. The <b>tkt_mtime</b> field of TICKETCHNG shows the timestamp on the ticket change artifact that the TICKETCHNG row refers to. The <b>tkt_ctime</b> field of TICKET is the time of the oldest ticket change artifact for that ticket, thus holding the time that the ticket was created. The <b>tkt_rid</b> field of TICKETCHNG is the integer primary key in the BLOB table of the ticket change artifact that gave rise to the row in the TICKETCHNG table. All the other fields of the TICKET and TICKETCHNG tables are available for customization for individual projects. None of the remaining fields are required, but all of them are needed in order to use the default ticket creating, viewing, and editing scripts. It is recommended that the other fields be retained and that customizations be restricted to adding new fields above and beyond the default. <h3>2.2 Translating Artifacts To Tables</h3> Each row in the TICKETCHNG table corresponds to a single ticket change artifact. The tkt_id field is the integer primary key of the TICKET table entry for the corresponding ticket. The tkt_rid field is the integer primary key for the BLOB table entry that contains the low-level artifact text. The tkt_mtime field is the time stamp on the ticket change artifact, expressed as a Julian day number. If the ticket change artifact contains a key/value pair where the key is "login", then the corresponding value is stored in the login field of the TICKETCHNG table. The same it true for "username", "mimetype", and "icomment" fields. Any time there is a key/value pair in the ticket change artifact and the key corresponds to the name of a field in the TICKETCHNG table, then the value of that key/value pair is stored in the TICKETCHNG table. If the TICKETCHNG table has a field for which there is no corresponding key/value pair in the artifact, then that field of the TICKETCHNG table is NULL. If there are key/value pairs in the artifact that have no corresponding field in the TICKETCHNG table, those key/value pairs are silently ignored. Each row in the TICKET table records the overall status of a ticket. The tkt_id field is a unique integer primary key for the ticket. the tkt_uuid field is the global ticket identifier - a larger random hexadecimal constant. The tkt_mtime and tkt_ctime fields hold the times of the most recent and the oldest ticket change artifacts for this ticket, respectively. To reconstruct the TICKET table, the ticket change artifacts are visited in time stamp order. As each ticket change artifact is visited, its key/value pairs are examined. For any key/value pair in which the key is the same as a field in the TICKET table, the value of that pair either replaces or is appended to the previous value of the corresponding field in the TICKET table. Whether a value is replaced or appended is determined by markings in the ticket change artifact itself. Most fields are usually replaced. (For example, to change the status from "Open" to "Fixed" would involve a key value pair "status/Fixed" with the replace attribute set). The main exception is the "comment" field, which is usually appended with new comment text. Note that the replace-or-append mark on ticket change artifacts is only used by the TICKET table. Since the initial value of all fields in the TICKETCHNG table is NULL, the replace-or-append mark makes no difference there. <h3>2.3 Old-Style versus New-Style Tickets</h3> Older versions of Fossil (before [/timeline?c=2012-11-27T16:26:29 | 2012-11-27]) only supported the TICKET table. In this older style, new comments were added to tickets by using the append-value feature on the comment field. Thus the TICKET.COMMENT field contains the complete text of all user comments already appended together and ready for display. A problem with the old approach is that all comment text had to be in the same format. In other words, the all comment text had to be either plaintext or wiki or HTML. It was not possible for some comments to be in HTML and others to be plaintext. Some site administrators wanted the ability to mix plaintext, wiki, and HTML comments and display each comment according to its chosen format. Hence, Fossil was enhanced to support the "new-style" tickets. The TICKETCHNG table was added to support new-style tickets. In the new style, comment text is stored with the "icomment" (for "Incremental Comment") key and appears separately, and with its own mimetype, in multiple rows of the TICKETCHNG table. It then falls to the TH1 script code on the View Ticket Page to query the TICKETCHNG table and extract and format the various comments in time stamp order. |

Unversioned files may have an optional directory name prefix. Though it omits history, Fossil does sync unversioned content between repositories. In the event of a conflict during a sync, it retains the most recent version of each unversioned file, discarding older versions. Unversioned files are useful for storing ephemeral content such as builds or frequently changing web pages. We store the [https://fossil-scm.org/home/uv/download.html|download] page of the self-hosting Fossil repository as unversioned content, for example. <h2>Accessing Unversioned Files</h2> Unversioned files are <u>not</u> a part of a check-out. Unversioned files are intended to be accessible as web pages using URLs of the form: "<tt>https://example.com/cgi-script/<b>uv</b>/<i>FILENAME</i></tt>". In other words, the URI method "<b>uv</b>" (short for "unversioned") followed by the name of the unversioned file will retrieve the content of the file. The MIME type is inferred from the filename suffix. The content of unversioned files can also be retrieved using the [/help?cmd=unversioned|fossil unvers cat <i>FILENAME...</i>] or [/help?cmd=unversioned|fossil unvers export <i>FILENAME</i>] commands. A list of all unversioned files on a server can be seen using the [/help?cmd=/uvlist|/uvlist] URL. ([/uvlist|example].) <h2>Syncing Unversioned Files</h2> Unversioned content does not sync between repositories by default. One must request it via commands such as: <pre> fossil sync <b>-u</b> fossil clone <b>-u</b> <i>URL local-repo-name</i> fossil unversioned sync </pre> The [/help?cmd=sync|fossil sync] and [/help?cmd=clone|fossil clone] commands will synchronize unversioned content if and only if they're given the "-u" (or "--unversioned") command-line option. The [/help?cmd=unversioned|fossil unversioned sync] command synchronizes the unversioned content without synchronizing anything else. Notice that the "-u" option does not work on [/help?cmd=push|fossil push] or [/help?cmd=pull|fossil pull]. The "-u" option is only available on "sync" and "clone". A rough equivalent of an unversioned pull would be the [/help?cmd=unversioned|fossil unversioned revert] command. The "unversioned revert" command causes the unversioned content on the local repository to be overwritten by the unversioned content found on the remote repository. Beware that because unversioned file sync is an uncommonly dangerous capability — there being no history to revert to in the case of human error — even the all-powerful Fossil "setup" user does not get unversioned file sync capability by default. See [./caps/admin-v-setup.md#dcap | this] for the full details, but the short-and-sweet takeaway is that a user needs the "y" capability on the remote before they can sync unversioned content. Until then, you're allowed to add such files to your local repo, but they will not sync. <h2>Implementation Details</h2> <i>(This section outlines the current implementation of unversioned files. This is not an interface spec and hence subject to change.)</i> Unversioned content is stored in the repository in the "unversioned" table: <pre> CREATE TABLE unversioned( uvid INTEGER PRIMARY KEY AUTOINCREMENT, -- unique ID for this file name TEXT UNIQUE, -- Name of the file rcvid INTEGER, -- From whence this file was received mtime DATETIME, -- Last change (seconds since 1970) hash TEXT, -- SHA1 or SHA3-256 hash of uncompressed content sz INTEGER, -- Size of uncompressed content encoding INT, -- 0: plaintext 1: zlib compressed content BLOB -- File content ); </pre> Fossil does not create the table ahead of need. If there are no unversioned files in the repository, the "unversioned" table will not exist. Consequently, one simple way to purge all unversioned content from a repository is to run: <pre> fossil sql "DROP TABLE unversioned; VACUUM;" </pre> Lacking history for unversioned files, Fossil does not attempt delta compression on them. Fossil servers exchange unversioned content whole; it does not attempt to "diff" your local version against the remote and send only the changes. We point this out because one use-case for unversioned content is to send large, frequently-changing files. Appreciate the consequences before making each change. There are two bandwidth-saving measures in "<tt>fossil uv sync</tt>". The first is the regular HTTP payload compression step, done on all syncs. The second is that Fossil sends hash exchanges to determine when it can avoid sending duplicate content over the wire unnecessarily. See the [./sync.wiki|synchronization protocol documentation] for further information. |

This web interface provides everything you need to run a software development project: * [./bugtheory.wiki | Ticketing and bug tracking] * [./wikitheory.wiki | Wiki] * [./embeddeddoc.wiki | On-line documentation] * [./event.wiki | Technical notes] * [./forum.wiki | Forum] * [./chat.md | Chatroom] * Timelines * Full text search over all of the above * Status information * Graphs of revision and branching history * File and version lists and differences * Download historical versions as ZIP archives * Historical change data * Add and remove tags on check-ins * Move check-ins between branches * Revise check-in comments * Manage user credentials and access permissions * And so forth... (some [./webpage-ex.md|examples]) You get all of this, and more, for free when you use Fossil. There are no extra programs to install or setup. Everything you need is already pre-configured and built into the self-contained, stand-alone Fossil executable. As an example of how useful this web interface can be, the entire [./index.wiki | Fossil website], including the document you are now reading, is rendered using the Fossil web interface, with no enhancements, and little customization. <div class="indent"> <b>Key point:</b> <i>The Fossil website is just a running instance of Fossil! </div> Note also that because Fossil is a distributed system, you can run the web interface on your local machine while off network (for example, while on an airplane) including making changes to wiki pages and/or trouble ticket, then synchronize with your co-workers after you reconnect. When you clone a Fossil repository, you don't just get the project source code, you get the entire project management website. <h2>Very Simple Startup</h2> To start using the built-in Fossil web interface on an existing Fossil repository, simply type this: <pre>fossil ui existing-repository.fossil</pre> Substitute the name of your repository, of course. The "ui" command will start a web server running (it figures out an available TCP port to use on its own) and then automatically launches your web browser to point at that server. If you run the "ui" command from within an open check-out, you can omit the repository name: <pre>fossil ui</pre> The latter case is a very useful short-cut when you are working on a Fossil project and you want to quickly do some work with the web interface. Notice that Fossil automatically finds an unused TCP port to run the server on and automatically points your web browser to the correct URL. So there is never any fumbling around trying to find an open port or to type arcane strings into your browser URL entry box. The interface just pops right up, ready to run. The Fossil web interface is also very easy to setup and run on a network server, as either a CGI program or from inetd, or as an SCGI server. Details on how to do that are described further below. <h2>Things To Do Using The Web Interface</h2> You can view <b>timelines</b> of changes to the project. The default "Timeline" link on the menu bar takes you to a page that shows the 20 most recent check-ins, wiki page edits, ticket/bug-report changes, and/or blog entries. This gives a very useful snapshot of what has been happening lately on the project. You can click to go further back in time, if needed. Or follow hyperlinks to see details, including diffs and annotated diffs, of individual check-ins, wiki page edits, ticket changes, and blog edits. You can view and edit <b>tickets and bug reports</b> by following the "Tickets" link on the menu bar. Fossil is backed by an SQL database, so users with appropriate permissions can write new ticket report formats based on SQL query statements. Fossil is careful to prevent ticket report formats from doing any mischief on the database (it only allows SELECT statements to run) and it restricts access to sensitive data such as user passwords. So it is actually safe to let anonymous users on the internet write their own ticket formats if you like. In addition to viewing and/or creating report formats, you can also create new tickets or look at summaries or complete histories of existing tickets. Any changes you make will automatically merge with changes from your co-workers the next time your repository is synchronized. You can view and edit <b>wiki</b> by following the "Wiki" link on the menu bar. Fossil has its own easy-to-remember [/wiki_rules | markup rules], or if you prefer, it also supports [/md_rules | Markdown]. And, as with tickets, all of your edits will automatically merge with those of your co-workers when your repository synchronizes. You can view summary reports of <b>branches</b> in the check-in graph by visiting the "Branches" link on the menu bar. From those pages you can follow hyperlinks to get additional details. These screens allow you to easily keep track of what is going on with separate sub-teams within your project team. The "Files" link on the menu allows you to browse through the <b>file hierarchy</b> of the project and to view complete changes histories on individual files, with hyperlinks to the check-ins that made those changes, and with diffs and annotated diffs between versions. The web interface supports [./embeddeddoc.wiki | embedded documentation] files (usually in wiki format) that are checked into the project as part of the source tree. Such files can be viewed as if they were ordinary web pages. This document that you are now reading is an example of embedded documentation. <h2>Customizing The Web Interface Appearance</h2> Users with appropriate permissions can customize the look and feel of the web interface using the "Admin" link on the main menu of the web interface. Templates for the header and footer of each page can be edited, as can the CSS for the entire page. You can even change around the main menu. Timeline display preferences can be edited. The page that is brought up as the "Home" page can be changed. It is often useful to set the "Home" page to be a wiki page or an embedded document. The built-in pages <b>/home</b> and <b>/index</b> can be used as the "Home" page. They have identical effect, which is to instruct Fossil to find and display a wiki page with the same name as the project, or if that does not exist, <b>/README.md</b> or <b>/index.wiki</b>. An embedded document link such as <b>doc/trunk/README.md</b> can be used for the "Home" page. If you specify one of the built-in keywords <b>/home</b> or <b>/index</b>, the page will not be treated as an embedded document. <h2>Installing On A Network Server</h2> When you create a new Fossil project and after you have configured it like you want it using the web interface, you can make the project available to a distributed team by simply copying the single repository file up to a web server that supports CGI or SCGI. To run Fossil as CGI, just put the <b>sample-project.fossil</b> file in a directory where CGI scripts have both read and write permission on the file and the directory that contains the file, then add a CGI script that looks something like this: <verbatim>#!/usr/local/bin/fossil repository: /home/www/sample-project.fossil</verbatim> Adjust the script above so that the paths are correct for your system, of course, and also make sure the Fossil binary is installed on the server. But that is <u>all</u> you have to do. You now have everything you need to host a distributed software development project in less than five minutes using a two-line CGI script. Instructions for setting up an SCGI server are [./scgi.wiki | available separately]. You don't have a CGI- or SCGI-capable web server running on your server machine? Not a problem. The Fossil interface can also be launched via inetd or xinetd. An inetd configuration line sufficient to launch the Fossil web interface looks like this: <verbatim>80 stream tcp nowait.1000 root /usr/local/bin/fossil \ /usr/local/bin/fossil http /home/www/sample-project.fossil</verbatim> As always, you'll want to adjust the pathnames to whatever is appropriate for your system. The xinetd setup uses a different syntax but follows the same idea. |

# Why Add Forum, Wiki, and Web Software To Your DVCS?
One notable feature of Fossil is that it bundles
[bug tracking](./bugtheory.wiki),
[wiki](./wikitheory.wiki),
[forum](./forum.wiki),
[chat](./chat.md), and
[technotes](./event.wiki)
with distributed version control to give you an
all-in-one software project management system.
A commenter on [Hacker News](https://news.ycombinator.com/item?id=27437895)
takes exception to this idea, writing:
> *I don't want forum/web software built into my dvcs.*
> *I don't see how this improves over git.*
This commenter may hold whatever opinions he wishes, of course.
However, there are many good reasons why bundling other project management
features with the DVCS might be useful for a given project:
1. There is a single software package to install and manage for the
project website.
The alternative is to select, install, configure, learn about,
manage, and maintain separate DVCS, wiki,
ticketing, forum,
chat, documentation, and whatever other software packages your project needs.
Less time spent on project administration details means more
time available to spend on the project itself.
2. Fossil’s autosync feature gives you an implicit backup of the
wiki, tickets, forum, and so forth simply by cloning the
repository to another machine and using that clone regularly.
Since the typical Fossil usage pattern is to stand the repo up on a
central server and have the developers clone that repository down
to their personal machines, if the server falls over, the last
developer to do anything that resulted in an autosync has a
functional and up-to-date backup.
There are [limitations to relying on Fossil’s autosync feature for
backup purposes](./backup.md), but that document gives two methods
for more complete backups, both of which are easily automated. The
Fossil project itself is distributed across three data centers in
this manner via cron.
3. Remote workers get more than just the source code:
they get the entire website including versioned documentation,
wiki articles, tickets, forum posts, and so forth. This supports
off-network development when traveling, when riding out Internet
service failures, and when workers must sync with multiple remote
servers, as when working alternately from home and in some central
office.
Feature-competitive Fossil alternatives typically solve this same
problem with centralization, which generally means that only the
DVCS piece still works in these situations where the developer is
unable to contact the central server. Why accept the limitation of
having a distributed clone of the code repo alone?
Centralization doesn’t work for every project. If you enjoy the
benefits of truly distributed (read: non-centralized) version
control, you may also benefit from distributed forums, distributed
ticket tracking, distributed wiki article publishing, and so
forth.
4. Integration of all of these features allows easy hyperlinks between
check-in comments, wiki pages, forum posts, and tickets. More,
because the software sees both sides of the link, referrer and
referent, it can provide automatic back-references.
A common situation in a Fossil project is that:
* a forum post refers to a versioned project document that shows
that the software isn’t behaving as documented;
* a developer triages that forum report as a verified bug, filing
a ticket to prioritize and track the resolution;
* developers chat about the problem, referring to the ticket and
thereby indirectly referring to the forum post, plus perhaps to
other Fossil-managed resources such as a wiki document giving
design principles that guide the proper fix; and finally
* the commit message resolving the ticket includes a reference to
the ticket it resolves.
Since Fossil sees that the commit refers to a ticket, the ticket
page automatically also refers back to the commit, closing the
loop. A latecomer may arrive at the ticket via a web search, and
from that see that it was closed following a commit. They can
follow the link from the initial ticket message to the forum
thread to catch up on the discussion leading to the fix and likely
find a follow-up post from the initial reporting user saying
whether the fix worked for them. If further work was needed, the
latecomer can likely find it from that forum thread.
This works even in a remote off-network clone: the developer can
pull up the project web site via an `http://localhost` link and
follow these links around the loop.
Fossil allows breaking some of these project facilities out into
separate repositories, as when the public forum is kept separate
from the actual software development repository for administration
reasons. By using Fossil’s [interwiki link
feature](./interwiki.md), you can get this same internal linking
from ticket to commit to forum to wiki even across these
administrative boundaries, even with remote off-network clones,
simply by adjusting the interwiki map to match the remote clone’s
network configuration.
5. Bundling all of these services gives [single sign-on][SSO] (SSO) for all
aspects of the project. The same username/password works for code,
wiki, forum, tickets, and chat.
If you choose to administratively separate some of these features
by setting up multiple cooperating Fossil repositories, its [login
groups feature](./caps/login-groups.md) allows asymmetric SSO
across these administrative boundaries so that, for example, users
allowed to commit to the code repository also get a forum
repository login, but self-registered forum users don’t
automatically get the ability to commit to the code repo.
6. Bundling all of these features reduces the number of external
dependencies for the project.
Take the first two points above: standing up a Fossil repo backup
on a new server may be as simple as copying the backup to the new
server and [configuring its stock HTTP server to point at the
backup repository via CGI](./server/any/cgi.md).
Consider: If you had good backups for all of the elements in a
Git + [Jira] + [Discord] + [MediaWiki] + [Sphinx] lash-up, how long
would it take you to stand up a replacement? That lash-up
certainly has more features combined than Fossil alone, but are
they worth the administration and hosting costs they impose?
Fossil’s feature set suffices for the SQLite project it was
created to serve, as well as for many others; is your project
sufficiently more complex, such that it *needs* all of those extra
features and their concomitant complexity?
Considerations such as these push many into centralized hosting
services such as GitHub, GitLab, Bitbucket, and so forth, but that
just takes you back to point 3 above.
7. Hosting all of these elements within a single service gives a
consistent look-and-feel across all aspects of the project.
Skinning independent software packages’ web interfaces to make
them appear unified is more work than [skinning] everything once, as
in Fossil, and even then, you can’t make independently-developed
software look like it was produced by a single entity without
resorting to heroic levels of customization. If you use a separate
DVCS web front end, chat system, forum manager, documentation
system, ticket tracker, and so on, you are likely to be relegated
to simply matching colors and fonts; you *might* also get the
ability to add a common logo to the header of all of these
independent pieces. The pieces won’t look unified, because they
weren’t developed that way.
The Fossil project’s
skinning system lets you affect all of its elements globally from the
single skin editor.
Or not: there’s a feature in Fossil that lets skin customizations
apply to only *some* Fossil features. The initial impetus behind
this feature was that one of our users wanted Markdown to be
rendered with different indentation in forum posts than in
[embedded documentation][edoc] owing to the inherent differences between
the two presentation modalities.
A user taking advantage of this per-feature CSS capability who
wishes to change a UI element common to all Fossil features — say,
to change the font for literal code blocks — may still make such a
change globally. Opting into this per-feature CSS doesn’t fork all
skinning efforts: UI elements not explicitly reskinned on a
per-feature basis inherit the global skinning.
But it goes futher. Fossil has a feature for [project-specific
extensions](./serverext.wiki), which backs the [SQLite Release
Checklist][srckl], for instance. You wouldn’t know by looking at
that page that it’s produced by software that isn’t actually part
of Fossil: the extension only delivers the core of the page,
and Fossil’s skining wraps it in a way that lets it inherit all of
the project-level skinning customizations.
8. Unifying all of these features within Fossil
means we have a single Markdown interpreter common to all
elements. If you lash multiple software systems together, even if
they can all agree on Markdown as a common document markup
language — hardly a given, as shown by the MediaWiki and Sphinx
elements in point 6’s example above — they’re likely to render your text
using different — possibly even incompatibly-different — Markdown
dialects.
This costs you in mental gear-switching when moving from the code
repository to the documentation system to the forums to the ticket
tracker.
More than that, though, a developer might write a forum post that later gets
promoted to a wiki article or to an embedded version-controlled
project document. A developer on a Fossil-backed project may simply copy-paste the forum post
text into the new document and save it, not needing to carefully
check that it still renders properly under the second Markdown
rendering engine. Similarly, if a user reports a potential bug via
the forum, the developer can copy interesting pieces of the
Markdown from the post into a ticket comment, again without
needing to fiddle with dialect incompatibilities.
9. Fossil is [free, open-source software](../COPYRIGHT-BSD2.txt),
through and through. Git-backed lash-ups tend to incorporate
either proprietary add-ons or proprietary hosting systems that
produce vendor lock-in. Fossil gives you the freedom to take your
complete backup (point 2) of the project including its
idiosyncratic customizations and stand it up elsewhere on
commodity hardware and software stacks.
All of this having been said, the non-DVCS features of Fossil are
optional. Its forum and chat features are disabled by default, and you
can disable the ticket-tracking and wiki features with a quick
configuration change to its [role-based access control system](./caps/).
When you’re ready to turn these additional features on, you can do so
with a few mouse clicks.
Because Fossil is web-native out of the box, if you’ve delegated these
features to outside systems to flesh out Git’s DVCS-only nature, you are
free to do the same with Fossil. One of the many things the [skinning]
facility allows is replacing the built-in links to the wiki, forum,
ticket system, etc. with links to external systems. How easy those
systems make it to link back into Fossil is up to their developers.

</ol>
<h5 id="definitions">II. Definitions</h5>
<div class="indent">Moved to [./glossary.md | a separate document].</div>
<h5>III. Basic Fossil commands</h5>
<ul>
<li><p><b>clone</b> →
Make a copy of a repository. The original repository
is usually (but not always) on a remote machine and the copy is on
the local machine. The copy remembers the network location from
which it was copied and (by default) tries to keep itself synchronized
with the original.
<li><p><b>open</b> →
Create a new check-out from a repository on the local machine.
<li><p><b>update</b> →
Modify an existing check-out so that it is derived from a
different version of the same project.
<li><p><b>commit</b> →
Create a new version (a new check-in) of the project that
is a snapshot of the current check-out.
<li><p><b>revert</b> →
Undo all local edits on a check-out. Make the check-out
be an exact copy of its associated check-in.
<li><p><b>push</b> →
Copy content found in a local repository over to a remote
repository. (Fossil usually does this automatically in response to
a "commit" and so this command is seldom used, but it is important
to understand it.)
<li><p><b>pull</b> →
Copy new content found in a remote repository into a local
repository. A "pull" by itself does not modify any check-out. The
"pull" command only moves content between repositories. However,
the "update" command will (often) automatically do a "pull" before
attempting to update the local check-out.
<li><p><b>sync</b> →
Do both a "push" and a "pull" at the same time.
<li><p><b>add</b> →
Add a new file to the local check-out. The file must already be
on disk. This command tells Fossil to start tracking and managing
the file. This command affects only the local check-out and does
not modify any repository. The new file is inserted into the
repository at the next "commit" command.
<li><p><b>rm/mv</b> →
Short for 'remove' and 'move', these commands are like "add"
in that they specify pending changes to the structure of the check-out.
As with "add", no changes are made to the repository until the next
"commit".
</ul>
<h5>IV. The history of a project is a Directed Acyclic Graph (DAG)</h5>
<ul>
<li><p>Fossil (and other distributed VCSes like Git and Mercurial, but
not Subversion) represent
the history of a project as a directed acyclic graph (DAG).
<ul>
<li><p>Each check-in is a node in the graph
<li><p>If check-in Y is derived from check-in X then there is
an arc in the graph from node X to node Y.
<li><p>The older check-in (X) is call the "parent" and the newer
check-in (Y) is the "child". The child is derived from
the parent.
</ul>
<li><p>Two users (or the same user working in different check-outs)
might commit different changes against the same check-in. This
results in one parent node having two or more children.
<li><p>Command: <b>merge</b> →
combines the work of multiple check-ins into
a single check-out. That check-out can then be committed to create
a new check-in that has two (or more) parents.
<ul>
<li><p>Most check-ins have just one parent, and either zero or
one child.
<li><p>When a check-in has two or more parents, one of those parents
is the "primary parent". All the other parent nodes are "secondary"
or "merge" parents.
Conceptually, the primary parent shows the main line of
development. Content from the merge parents is added
into the main line.
<li><p>The "direct children" of a check-in X are all children that
have X as their primary parent.
<li><p>A check-in node with no direct children is sometimes called
a "leaf".
<li><p>The "merge" command changes only the check-out.
The "commit" command must be run subsequently to make the merge
a permanent part of project.
</ul>
<li><p>Definition: <b>branch</b> →
a sequence of check-ins that are all linked
together in the DAG through the primary parent.
<ul>
<li><p>Branches are often given names which propagate to direct children.
The tradition in Fossil is to call the main branch "trunk". In
Git, it's called "master" by default, though some call it
something else, like "main".
<li><p>It is possible to have multiple branches with the same name.
Fossil has no problem with this, but it can be confusing to
humans, so best practice is to give each branch a unique name.
<li><p>The name of a branch can be changed by adding special tags
to the first check-in of a branch. The name assigned by this
special tag automatically propagates to all direct children.
</ul>
</ul>
<h5>V. Why version control is important (reprise)</h5>
<ol>
<li><p>Every check-in and every individual file has a unique name - its
SHA1 or SHA3-256 hash. Team members can unambiguously identify
any specific
version of the overall project or any specific version of an
individual file.
<li><p>Any historical version of the whole project or of any individual
file can be easily recreated at any time and by any team member.
<li><p>Accidental changes to files can be detected by recomputing their
cryptographic hash.
<li><p>Files of unknown origin can be identified using their hash.
<li><p>Developers are able to work in parallel, review each others work,
and easily merge their changes together. External revisions to
the baseline can be easily incorporated into the latest changes.
<li><p>Developers can follow experimental lines of development, then
revert back to an earlier stable version if the experiment does
not work out. Creativity is enhanced by allowing crazy ideas to
be investigated without destabilizing the project.
<li><p>Developers can work on several independent subprojects, flipping
back and forth from one subproject to another at will, and merge
patches together or back into the main line of development as they
mature.
<li><p>Older changes can be easily backed out of recent revisions, for
example if bugs are found long after the code was committed.
<li><p>Enhancements in a branch can be easily copied into other branches,
or into the trunk.
<li><p>The complete history of all changes is plainly visible to
all team members. Project leaders can easily keep track of what
all team members are doing. Check-in comments help everyone to
understand and/or remember the reason for each change.
<li><p>New team members can be brought up-to-date with all of the historical
code, quickly and easily.
<li><p>New developers, interns, or inexperienced staff members who still
do not understand all the details of the project or who are otherwise
prone to making mistakes can be assigned significant subprojects to
be carried out in branches without risking main line stability.
<li><p>Code is automatically synchronized across all machines. No human
effort is wasted copying files from machine to machine. The risk
of human errors during file transfer and backup is eliminated.
<li><p>A hardware failure results in minimal lost work because
all previously committed changes will have been automatically
replicated on other machines.
<li><p>The complete work history of the project is conveniently archived
in a single file, simplifying long-term record keeping.
<li><p>A precise historical record is maintained which can be used to
support copyright and patent claims or regulatory compliance.

<title>Wiki In Fossil</title>
<h2>Introduction</h2>
Fossil uses [/wiki_rules | Fossil wiki markup] and/or
[/md_rules | Markdown markup] for many things:
* Stand-alone wiki pages.
* Description and comments in [./bugtheory.wiki | bug reports].
* Check-in comments. (For historical reasons, these must
currently be in fossil-wiki text format.)
* [./embeddeddoc.wiki | Embedded documentation] files whose
name ends in ".wiki" or ".md" or ".markdown".
* [./event.wiki | Technical notes].
* [./forum.wiki | Forum messages].
* Auxiliary notes on check-ins and branches.
The [/wiki_rules | formatting rules for fossil wiki]
are designed to be simple and intuitive. The idea is that wiki provides
paragraph breaks, numbered and bulleted lists, and hyperlinking for
simple documents together with a safe subset of HTML for more complex
formatting tasks.
The [/md_rules | Markdown formatting rules] are more complex, but
are also more widely known, and are thus provided as an alternative.
<h2>Stand-alone Wiki Pages</h2>
Each wiki page has its own revision history which is independent of
the sequence of check-ins (check-ins). Wiki pages can branch and merge
just like check-ins, though as of this writing (2008-07-29) there is
no mechanism in the user interface to support branching and merging.
The current implementation of the wiki shows the version of the wiki
page that has the most recent time stamp.
In other words, if two users make unrelated changes to the same wiki
page on separate repositories and those repositories are synced,
the wiki page will fork. The web interface will display whichever edit
was checked in last. The other edit can be found in the history. The
file format will support merging the branches back together, but there
is no mechanism in the user interface (yet) to perform the merge.
Every change to a wiki page is a separate
[./fileformat.wiki | control artifact]
of type [./fileformat.wiki#wikichng | "Wiki Page"].
<h2>Embedded Documentation</h2>
Files in the source tree that use the ".wiki", ".md", or ".markdown" suffixes
can be accessed and displayed using special URLs to the fossil server.
This allows
project documentation to be stored in the source tree and accessed
online. (Details are described [./embeddeddoc.wiki | separately].)
Some projects prefer to store their documentation in wiki. There is nothing
wrong with that. But other projects prefer to keep documentation as part
of the source tree, so that it is versioned along with the source tree and
so that only developers with check-in privileges can change it.
Embedded documentation serves this latter purpose. Both forms of documentation
use the exact same markup. Some projects may choose to
use both forms of documentation at the same time. Because the same
format is used, it is trivial to move a file from wiki to embedded documentation
or back again as the project evolves.
<h2>Bug-reports and check-in comments and Forum messages</h2>
The comments on check-ins, forum posts, and the text in the
descriptions of bug reports both use wiki formatting. Exactly the
same set of formatting rules apply. There is never a need to learn
one formatting language for documentation and a different markup for
bugs or for check-in comments.
Minor caveat: check-in messages are currently limited to the
fossil-wiki format.
<h2 id="assocwiki">Auxiliary notes attached to check-ins or branches</h2>
Stand-alone wiki pages with special names "branch/<i>BRANCHNAME</i>"
or "checkin/<i>HASH</i>" are associated with the corresponding
branch or check-in. The wiki text appears in an "About" section of
timelines and info screens. Examples:
* [/timeline?r=graph-test-branch] shows the text of the
[/wiki?name=branch/graph-test-branch&p|branch/graph-test-branch]
wiki page at the top of the timeline
* [/info/19c60b7fc9e2] shows the text of the
[/wiki?name=checkin/19c60b7fc9e2400e56a6f938bbad0e34ca746ca2eabdecac10945539f1f5e8c6&p|checkin/19c60b7fc9e2...]
wiki page in the "About" section.
These special wiki pages are very useful for recording historical
notes.

Note that these criteria apply conjunctively; if any are not met, then the consequences of the issues below are at worst annoying and otherwise harmless or absent. <h2>What Can Go Wrong (Why It Matters)</h2> The most readily seen manifestation of the problem occurs when "<tt>fossil status</tt>" or "<tt>fossil changes</tt>" is run, using Linux Fossil from WSL after Windows tools (including fossil.exe) have been used to modify files within a checkout. Unless filter options block it, those subcommands will tag some (and often many) checkout files with <b>EXECUTABLE</b> or <b>NOEXEC</b>, indicating that the file's user execute permission has been altered such that it differs from what is recorded in the repository for that version of the file. This "user execute permission" is referred to as "the X-bit" hereafter, referring to either the recorded version state or a checkout file attributes state. This is merely annoying and distracting if the altered X-bit will never be committed using Linux Fossil. It can be quite distracting because those tags tend to mask the presence or absence of other changes whose detection is the usual reason for using Fossil's changes or status subcommands. However, in the problematic usage scenario, those tags will most often represent inadvertant toggling of the X-bit on the affected file. The X-bit is kept in the repository for good reason (usually), and arbitrary changes to it by means of a commit when that change is not intended is virtually always a bad result. (At best, the change causes useless churn; at worst it frustrates the intended purpose of having an X-bit.) <h2>Technical Discusion of the Problem</h2> The genesis of altered X-bits, while not obvious at first glance, involves obvious facts. The Windows OS does not deal with the triple of user/group/other executable permissions the way that Unix and similar operating systems do. Hence, tools which run on Windows, including Fossil built for Windows, do not manage the X-bit; it may not even exist yet for files which have not had their permissions set by any Linux program running in WSL. When such tools modify a file which has had its X-bit set (or cleared) by a program in WSL, an existing X-bit value may not be preserved depending upon how the modification is effected. The WSL infrastructure (or virtual system) compensates for the absence of an X-bit in Windows filesystems with two stratagems: (1) Establishing a default for its value when no Linux program has yet set it; and (2) stashing Linux "mode" bits in a "special" place for each file once it has been subject to a chmod() call. That default's default can be changed by way of /etc/wsl.conf content. However, this default cannot be right for files which are tracked in a Fossil repository as having the other value. And Windows tools generally are not written to deal with "mode" bits in that "special" place. (They are kept in a NTFS extended file attribute named $LXMOD, not accessible through the WIN32 API; the OS layer below WIN32 must be used to get at them.) Hence, inadvertant X-bit changes are unavoidable, or avoided only by luck, in the general usage case noted above. <h2>Problematic Usage Scenarios</h2> <h3>A Simple Example</h3> * Open a checkout in Windows (using fossil.exe) from a project whose files have a mixture of executable and non-executable files. Use a checkout directory visible when running under WSL. * Navigate to the same directory in a Linux shell on WSL, then run "fossil status". * Depending upon /etc/wsl.conf content (or defaults in its absence), the status ouput will tag checkout files as EXECUTABLE or NOEXEC. <h3>Continuation of Simple Example</h3> * In the same checkout as above "Simple Example", on WSL, run "fossil revert" to correct all those errant X-bit values. * Run "fossil status" again in WSL to verify absence of toggled X-bits. * Run "ls -l" from WSL to find two files, one with its X-bit set and the other with it clear. * From Windows, perform these steps on each of those files:<br> (1) read the_file content into a buffer<br> (2) rename the_file the_file.bak<br> (3) write buffer content to new file, the_file<br> (4) del the_file.bak (or leave it)<br> (Note that this sequence is similar to what many editors do when a user modifies a file then uses undo to reverse the changes.) * Run "fossil status" again in WSL and observe that one of the two files has had its X-bit toggled. <h3>A Fossil-Only Example</h3> * In the another (different) checkout of the same version, somehow cause "legitimate" X-bit toggles of two files whose X-bits differ. (This "somehow" probably will involve WSL to toggle file bits and fossil on WSL to commit the toggles.) * In the Simple Example checkout, use fossil.exe on Windows to update the checkout, ostensibly bringing the X-bit toggles into the affected checkout files. * In the Simple Example checkout, use fossil on WSL to run "fossil status", and observe at least one X-bit discrepancy. <h2>Recommended Workflow</h2> There are two simple approaches for dealing with this issue when one wishes to continue using the same checkout directory from Windows and WSL. Either one is effective. These are: * Do not use fossil on WSL for any operations which will modify the repository. Instead, block those operations in some manner. * Do not use any tools on Windows, (including certain subcommands of fossil.exe,) which may modify the X-bits on files within the shared checkout, instead restricting use of Windows tools to those which are known to only (and actually) modify file content in place while preserving X-bit values. (The "actually" proviso emphasizes that tools which only simulate in-place file modification, but do so via create combined with delete and rename, are to be avoided. A simulation which works flawlessly on Windows may not preserve the WSL X-bit.) There are more complex ways to deal with this issue, involving use of fossil on WSL to fix (or revert) toggled X-bits prior to any commit, together with actions needed to preserve all intended changes to the checkout as fossil revert is done. Such methods are overly clever or fragile for elaboration here. Another way to deal with this issue is to correct any toggled X-bits within a checkout before using "fossil commit" on WSL by means other than "fossil revert". <h2>Corrective Measures or Mitigation</h2> It is possible, by either manual or automated means, to perform a pre-commit check and/or correction for mis-toggled X-bits. The X-bit states are available from the repository for whatever versions it has stored. And several Linux tools are able to read or alter the X-bit state of files. With these components, a tool can be readily built to aid avoidance of a commit (via fossil on WSL) that would record mis-toggled X-bits into the repository. Fossil itself on WSL will detect mis-toggled X-bits for files which have not been otherise modified, but altered file content masks such detection, and it is just such modification that is among the problematic scenarios. So Fossil alone cannot yet reliably do the detection or correction needed to avoid or remedy the mis-toggled X-bit commit problem. It is also feasible to detect or correct the mis-toggled X-bit problem within Windows with a special-purpose tool which can read, create or modify the X-bits stored by WSL for any file which has been subject to the Linux chmod(...) system call. Creation of these tools is beyond the scope of this document. |
