<repository>::
The "remote" repository that is the source of a fetch
or pull operation, or the destination of a push operation.
One of the following notations can be used
to name the remote repository:
+
===============================================================
- Rsync URL: rsync://remote.machine/path/to/repo.git/
- HTTP(s) URL: http://remote.machine/path/to/repo.git/
- git URL: git://remote.machine/path/to/repo.git/
or remote.machine:/path/to/repo.git/
- Local directory: /path/to/repo.git/
===============================================================
+
In addition to the above, as a short-hand, the name of a
file in `$GIT_DIR/remotes` directory can be given; the
named file should be in the following format:
+
URL: one of the above URL format
Push: <refspec>...
Pull: <refspec>...
+
When such a short-hand is specified in place of
<repository> without <refspec> parameters on the command
line, <refspec>... specified on `Push:` lines or `Pull:`
lines are used for `git-push` and `git-fetch`/`git-pull`,
respectively. Multiple `Push:` and and `Pull:` lines may
be specified for additional branch mappings.
+
The name of a file in `$GIT_DIR/branches` directory can be
specified as an older notation short-hand; the named
file should contain a single line, a URL in one of the
above formats, optionally followed by a hash `#` and the
name of remote head (URL fragment notation).
`$GIT_DIR/branches/<remote>` file that stores a <url>
without the fragment is equivalent to have this in the
corresponding file in the `$GIT_DIR/remotes/` directory.
+
URL: <url>
Pull: refs/heads/master:<remote>
+
while having `<url>#<head>` is equivalent to
+
URL: <url>
Pull: refs/heads/<head>:<remote>
<refspec>::
The canonical format of a <refspec> parameter is
`+?<src>:<dst>`; that is, an optional plus `+`, followed
by the source ref, followed by a colon `:`, followed by
the destination ref.
+
When used in `git-push`, the <src> side can be an
arbitrary "SHA1 expression" that can be used as an
argument to `git-cat-file -t`. E.g. `master~4` (push
four parents before the current master head).
+
For `git-push`, the local ref that matches <src> is used
to fast forward the remote ref that matches <dst>. If
the optional plus `+` is used, the remote ref is updated
even if it does not result in a fast forward update.
+
For `git-fetch` and `git-pull`, the remote ref that matches <src>
is fetched, and if <dst> is not empty string, the local
ref that matches it is fast forwarded using <src>.
Again, if the optional plus `+` is used, the local ref
is updated even if it does not result in a fast forward
update.
+
[NOTE]
If the remote branch from which you want to pull is
modified in non-linear ways such as being rewound and
rebased frequently, then a pull will attempt a merge with
an older version of itself, likely conflict, and fail.
It is under these conditions that you would want to use
the `+` sign to indicate non-fast-forward updates will
be needed. There is currently no easy way to determine
or declare that a branch will be made available in a
repository with this behavior; the pulling user simply
must know this is the expected usage pattern for a branch.
+
[NOTE]
You never do your own development on branches that appear
on the right hand side of a <refspec> colon on `Pull:` lines;
they are to be updated by `git-fetch`. The corollary is that
a local branch should be introduced and named on a <refspec>
right-hand-side if you intend to do development derived from
that branch.
This leads to the common `Pull: master:origin` mapping of a
remote `master` branch to a local `origin` branch, which
is then merged to a local development branch, again typically
named `master`.
+
Some short-cut notations are also supported.
+
* For backward compatibility, `tag` is almost ignored;
it just makes the following parameter <tag> to mean a
refspec `refs/tags/<tag>:refs/tags/<tag>`.
* A parameter <ref> without a colon is equivalent to
<ref>: when pulling/fetching, and <ref>`:`<ref> when
pushing. That is, do not store it locally if
fetching, and update the same name if pushing.
