test_cleanup

is a duplicate of a remote repository.

Communication between repositories is via 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><a id="artifacts"></a>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

otherwise just the listed file(s) will be checked in.

<h2>Compare two revisions of a file</h2>
<p>If you wish to compare the last revision of a file and its checked out version
in your work directory:</p>
<p>fossil gdiff myfile.c</p>
<p>If you wish to compare two different revisions of a file in the repository:</p>
<p>fossil finfo myfile: Note the first hash, which is the hash of the commit
when the file was committed</p>
<p>fossil gdiff --from HASH#1 --to HASH#2 myfile.c</p>
<h2>Cancel changes and go back to previous revision</h2>
<p>fossil revert myfile.c</p>
<p>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.</p>

# 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
{
"type":"checkin",
"name":"18dd383e5e7684e", // as given on CLI
"uuid":"18dd383e5e7684ecee327d3de7d3ff846069d1b2",
"isLeaf":false,
"user":"drh",
"comment":"Merge wideAnnotateUser and jsonWarnings into trunk.",
"timestamp":1330090810,
"parents":[
  // 1st entry is primary parent hash:
  "3a44f95f40a193739aaafc2409f155df43e74a6f",
  // Remaining entries are merged-in branch hashes:
  "86f6e675eb3f8761d70d8b82b052ce2b297fffd2",\
  "dbf4ecf414881c9aad6f4f125dab9762589ef3d7"\
],
"tags":["trunk"],
"files":[{
    "name":"src/diff.c",
    // BLOB hashes, NOT commit hashes:
    "uuid":"78c74c3b37e266f8f7e570d5cf476854b7af9d76",
    "parent":"b1fa7e636cf4e7b6ed20bba2d2680397f80c096a",
    "state":"modified",
    "downloadPath":"/raw/src/diff.c?name=78c74c3b37e266f8f7e570d5cf476854b7af9d76"
  },
  ...]
}
```

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].

# 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).

"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.

"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

-   `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!)**

  "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"
   }]

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

    "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`.

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.

**`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?
