|
|
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:

In addition to the above, as a short-hand, the name of a
|
2005-11-05 05:36:08 +03:00
|
|
|
file in `$GIT_DIR/remotes` directory can be given; the
|
2005-10-03 21:16:30 +04:00
|
|
|
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
|
2005-11-05 05:36:08 +03:00
|
|
|
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.

2005-11-05 05:36:08 +03:00
|
|
|
The name of a file in `$GIT_DIR/branches` directory can be
|
2005-10-03 21:16:30 +04:00
|
|
|
specified as an older notation short-hand; the named
|
|
|
|
|
file should contain a single line, a URL in one of the
|
2005-11-05 05:36:08 +03:00
|
|
|
above formats, optionally followed by a hash `#` and the
|
2005-10-03 21:16:30 +04:00
|
|
|
name of remote head (URL fragment notation).
|
2005-11-05 05:36:08 +03:00
|
|
|
`$GIT_DIR/branches/<remote>` file that stores a <url>
|
2005-10-03 21:16:30 +04:00
|
|
|
without the fragment is equivalent to have this in the
|
2005-11-05 05:36:08 +03:00
|
|
|
corresponding file in the `$GIT_DIR/remotes/` directory.
|
2005-10-03 21:16:30 +04:00
|
|
|
+
|
|
|
|
|
URL: <url>
|
|
|
|
|
Pull: refs/heads/master:<remote>
|
|
|
|
|
+
|
2005-11-05 05:36:08 +03:00
|
|
|
while having `<url>#<head>` is equivalent to
|
2005-10-03 21:16:30 +04:00
|
|
|
+
|
|
|
|
|
URL: <url>
|
|
|
|
|
Pull: refs/heads/<head>:<remote>
|
2005-08-25 03:23:08 +04:00
|
|
|
|
|
|
|
|
<refspec>::
|
|
|
|
|
The canonical format of a <refspec> parameter is
|
2005-11-05 05:36:08 +03:00
|
|
|
`+?<src>:<dst>`; that is, an optional plus `+`, followed
|
|
|
|
|
by the source ref, followed by a colon `:`, followed by
|
2005-08-25 03:23:08 +04:00
|
|
|
the destination ref.
|
2005-10-03 21:16:30 +04:00
|
|
|
+
|
2005-11-05 05:36:08 +03:00
|
|
|
When used in `git-push`, the <src> side can be an
|
2005-10-03 21:16:30 +04:00
|
|
|
arbitrary "SHA1 expression" that can be used as an
|
2005-11-05 05:36:08 +03:00
|
|
|
argument to `git-cat-file -t`. E.g. `master~4` (push
|
2005-10-03 21:16:30 +04:00
|
|
|
four parents before the current master head).
|
|
|
|
|
+
|
2005-11-05 05:36:08 +03:00
|
|
|
For `git-push`, the local ref that matches <src> is used
|
2005-10-03 21:16:30 +04:00
|
|
|
to fast forward the remote ref that matches <dst>. If
|
2005-11-05 05:36:08 +03:00
|
|
|
the optional plus `+` is used, the remote ref is updated
|
2005-10-03 21:16:30 +04:00
|
|
|
even if it does not result in a fast forward update.
|
|
|
|
|
+
|
2005-11-05 05:36:08 +03:00
|
|
|
For `git-fetch` and `git-pull`, the remote ref that matches <src>
|
2005-10-03 21:16:30 +04:00
|
|
|
is fetched, and if <dst> is not empty string, the local
|
|
|
|
|
ref that matches it is fast forwarded using <src>.
|
2005-11-05 05:36:08 +03:00
|
|
|
Again, if the optional plus `+` is used, the local ref
|
2005-10-03 21:16:30 +04:00
|
|
|
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.
|
|
|
|

|
2005-11-05 05:36:08 +03:00
|
|
|
* For backward compatibility, `tag` is almost ignored;
|
2005-10-03 21:16:30 +04:00
|
|
|
it just makes the following parameter <tag> to mean a
|
2005-11-05 05:36:08 +03:00
|
|
|
refspec `refs/tags/<tag>:refs/tags/<tag>`.
|
2005-10-03 21:16:30 +04:00
|
|
|
* A parameter <ref> without a colon is equivalent to
|
2005-11-05 05:36:08 +03:00
|
|
|
<ref>: when pulling/fetching, and <ref>`:`<ref> when
|
2005-10-03 21:16:30 +04:00
|
|
|
pushing. That is, do not store it locally if
|
|
|
|
|
fetching, and update the same name if pushing.
