While it is not *wrong* per-se to say that pulling a rewound/rebased branch will lead to an unnecessary merge conflict, that is not what the leading "+" sign to allow non-fast-forward update of remote-tracking branch is at all.

<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).
|
|
|
|
ifndef::git-pull[]
|
|
<group>::
|
|
A name referring to a list of repositories as the value
|
|
of remotes.<group> in the configuration file.
|
|
(See linkgit:git-config[1]).
|
|
endif::git-pull[]
|
|
|
|
<refspec>::
|
|
The format of a <refspec> parameter is an optional plus
|
|
`+`, followed by the source ref <src>, followed
|
|
by a colon `:`, followed by the destination ref <dst>.
|
|
+
|
|
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>.
|
|
If the optional plus `+` is used, the local ref
|
|
is updated even if it does not result in a fast-forward
|
|
update.
|
|
+
|
|
[NOTE]
|
|
When the remote branch you want to fetch is known to
|
|
be rewound and rebased regularly, it is expected that
|
|
its new tip will not be descendant of its previous tip
|
|
(as stored in your remote-tracking branch the last time
|
|
you fetched). You would want
|
|
to use the `+` sign to indicate non-fast-forward updates
|
|
will be needed for such branches. There is no 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.
|
|
ifndef::git-pull[]
|
|
* A parameter <ref> without a colon fetches that ref into FETCH_HEAD,
|
|
endif::git-pull[]
|
|
ifdef::git-pull[]
|
|
* A parameter <ref> without a colon merges <ref> into the current
|
|
branch,
|
|
endif::git-pull[]
|
|
and updates the remote-tracking branches (if any).
