<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://host.xz/path/to/repo.git/
|
|
- http://host.xz/path/to/repo.git/
|
|
- https://host.xz/path/to/repo.git/
|
|
- git://host.xz/path/to/repo.git/
|
|
- git://host.xz/~user/path/to/repo.git/
|
|
- ssh://host.xz/path/to/repo.git/
|
|
- ssh://host.xz/~user/path/to/repo.git/
|
|
- ssh://host.xz/~/path/to/repo.git
|
|
===============================================================
|
|
+
|
|
SSH Is the default transport protocol and also supports an
|
|
scp-like syntax. Both syntaxes support username expansion,
|
|
as does the native git protocol. The following three are
|
|
identical to the last three above, respectively:
|
|
+
|
|
===============================================================
|
|
- host.xz:/path/to/repo.git/
|
|
- host.xz:~user/path/to/repo.git/
|
|
- host.xz:path/to/repo.git
|
|
===============================================================
|
|
+
|
|
To sync with a local directory, use:
|
|
+
|
|
===============================================================
|
|
- /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`. If you intend to do
|
|
development derived from a remote branch `B`, have a `Pull:`
|
|
line to track it (i.e. `Pull: B:remote-B`), and have a separate
|
|
branch `my-B` to do your development on top of it. The latter
|
|
is created by `git branch my-B remote-B` (or its equivalent `git
|
|
checkout -b my-B remote-B`). Run `git fetch` to keep track of
|
|
the progress of the remote side, and when you see something new
|
|
on the remote branch, merge it into your development branch with
|
|
`git pull . remote-B`, while you are on `my-B` branch.
|
|
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`, is made
|
|
when you run `git clone` for you to follow this pattern.
|
|
+
|
|
[NOTE]
|
|
There is a difference between listing multiple <refspec>
|
|
directly on `git-pull` command line and having multiple
|
|
`Pull:` <refspec> lines for a <repository> and running
|
|
`git-pull` command without any explicit <refspec> parameters.
|
|
<refspec> listed explicitly on the command line are always
|
|
merged into the current branch after fetching. In other words,
|
|
if you list more than one remote refs, you would be making
|
|
an Octopus. While `git-pull` run without any explicit <refspec>
|
|
parameter takes default <refspec>s from `Pull:` lines, it
|
|
merges only the first <refspec> found into the current branch,
|
|
after fetching all the remote refs. This is because making an
|
|
Octopus from remote refs is rarely done, while keeping track
|
|
of multiple remote heads in one-go by fetching more than one
|
|
is often useful.
|
|
+
|
|
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.
