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:

{
"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.

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)

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 interpretted 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!)

{
"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"
 }]
}

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:

{
"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:

{
"raw":false,
"tags":{
  "json":null,
  "json-multitag-test":null
 }
}

The nulls there are the tag values (most tags don't have values).

If raw=true then the tags property changes slightly:

{
"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}.
