<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
