The previous text was correct, but it was easy to miss the fact that we are talking about "matching" refs. That is, the text can be parsed as "we push the union of the sets of remote and local heads" and not "we push the intersection of the sets of remote and local heads". (The former actually doesn't make sense if you think about it, since we don't even _have_ some of those heads). A careful reading would reveal the correct meaning, but it makes sense to be as explicit as possible in documentation. We also explicitly use and introduce the term "matching"; this is a term discussed on the list, and it seems useful to for users to be able to refer to this behavior by name.

git-push - Update remote refs along with associated objects
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git-push' [--all] [--dry-run] [--tags] [--receive-pack=<git-receive-pack>]
|
|
[--repo=all] [-f | --force] [-v | --verbose] [<repository> <refspec>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
Updates remote refs using local refs, while sending objects
|
|
necessary to complete the given refs.
|
|
|
|
You can make interesting things happen to a repository
|
|
every time you push into it, by setting up 'hooks' there. See
|
|
documentation for linkgit:git-receive-pack[1].
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
<repository>::
|
|
The "remote" repository that is destination of a push
|
|
operation. See the section <<URLS,GIT URLS>> 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 <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).
|
|
+
|
|
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.
|
|
+
|
|
Note: If no explicit refspec is found, (that is neither
|
|
on the command line nor in any Push line of the
|
|
corresponding remotes file---see below), then "matching" heads are
|
|
pushed: for every head that exists on the local side, the remote side is
|
|
updated if a head of the same name already exists on the remote side.
|
|
+
|
|
`tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
|
|
+
|
|
A parameter <ref> without a colon pushes the <ref> from the source
|
|
repository to the destination repository under the same name.
|
|
+
|
|
Pushing an empty <src> allows you to delete the <dst> ref from
|
|
the remote repository.
|
|
|
|
\--all::
|
|
Instead of naming each ref to push, specifies that all
|
|
refs under `$GIT_DIR/refs/heads/` be pushed.
|
|
|
|
\--mirror::
|
|
Instead of naming each ref to push, specifies that all
|
|
refs under `$GIT_DIR/refs/heads/` and `$GIT_DIR/refs/tags/`
|
|
be mirrored to the remote repository. Newly created local
|
|
refs will be pushed to the remote end, locally updated refs
|
|
will be force updated on the remote end, and deleted refs
|
|
will be removed from the remote end.
|
|
|
|
\--dry-run::
|
|
Do everything except actually send the updates.
|
|
|
|
\--tags::
|
|
All refs under `$GIT_DIR/refs/tags` are pushed, in
|
|
addition to refspecs explicitly listed on the command
|
|
line.
|
|
|
|
\--receive-pack=<git-receive-pack>::
|
|
Path to the 'git-receive-pack' program on the remote
|
|
end. Sometimes useful when pushing to a remote
|
|
repository over ssh, and you do not have the program in
|
|
a directory on the default $PATH.
|
|
|
|
\--exec=<git-receive-pack>::
|
|
Same as \--receive-pack=<git-receive-pack>.
|
|
|
|
-f, \--force::
|
|
Usually, the command refuses to update a remote ref that is
|
|
not an ancestor of the local ref used to overwrite it.
|
|
This flag disables the check. This can cause the
|
|
remote repository to lose commits; use it with care.
|
|
|
|
\--repo=<repo>::
|
|
When no repository is specified the command defaults to
|
|
"origin"; this overrides it.
|
|
|
|
\--thin, \--no-thin::
|
|
These options are passed to `git-send-pack`. Thin
|
|
transfer spends extra cycles to minimize the number of
|
|
objects to be sent and meant to be used on slower connection.
|
|
|
|
-v, \--verbose::
|
|
Run verbosely.

Examples
|
|
--------
|
|
|
|
git push origin master::
|
|
Find a ref that matches `master` in the source repository
|
|
(most likely, it would find `refs/heads/master`), and update
|
|
the same ref (e.g. `refs/heads/master`) in `origin` repository
|
|
with it.
|
|
|
|
git push origin :experimental::
|
|
Find a ref that matches `experimental` in the `origin` repository
|
|
(e.g. `refs/heads/experimental`), and delete it.
|
|
|
|
git push origin master:satellite/master::
|
|
Find a ref that matches `master` in the source repository
|
|
(most likely, it would find `refs/heads/master`), and update
|
|
the ref that matches `satellite/master` (most likely, it would
|
|
be `refs/remotes/satellite/master`) in `origin` repository with it.
|
|
|
|
git push origin master:refs/heads/experimental::
|
|
Create the branch `experimental` in the `origin` repository
|
|
by copying the current `master` branch. This form is usually
|
|
needed to create a new branch in the remote repository as
|
|
there is no `experimental` branch to match.
