The names of git commands are not meant to be entered at the
commandline; they are just names. So we render them in italics,
as is usual for command names in manpages.

<repository>::
|
|
The "remote" repository that is the source of a fetch
|
|
or pull operation. This parameter can be either a URL
|
|
(see the section <<URLS,GIT URLS>> below) or the name
|
|
of a remote (see the section <<REMOTES,REMOTES>> below).
|
|
|
|
<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.
|
|
+
|
|
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.
|
|
+
|
|
[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.
|
|
+
|
|
* `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`;
|
|
it requests fetching everything up to the given tag.
|
|
* A parameter <ref> without a colon is equivalent to
|
|
<ref>: when pulling/fetching, so it merges <ref> into the current
|
|
branch without storing the remote branch anywhere locally
