Local executing hook after a git push?

问题

I\'ve looked at the githooks manpage but unless I\'m missing something I don\'t see an option for local, post-push git hooks. I\'d like to have one that updates the api docs on my web server (for which I already have a script) after I push the master branch to the GitHub repo. Of course I could just write my own script that combines the git push and the api docs run, but that feels somewhat inelegant.

回答1:

From Git 1.8.2 there is a new hook invoked before the push operation: pre-push If the script returns other than 0 the push operation will be cancelled.

Mention in the release notes: https://github.com/git/git/blob/master/Documentation/RelNotes/1.8.2.txt#L167

Sample: https://github.com/git/git/blob/87c86dd14abe8db7d00b0df5661ef8cf147a72a3/templates/hooks--pre-push.sample

回答2:

Another solution to this problem is to have a wrapper for git push that executes .git/hooks/pre-push and .git/hooks/post-push scripts before and after the git push call. A possible wrapper could look like this:

#!/bin/sh

GIT_DIR_="$(git rev-parse --git-dir)"
BRANCH="$(git rev-parse --symbolic --abbrev-ref $(git symbolic-ref HEAD))"

PRE_PUSH="$GIT_DIR_/hooks/pre-push"
POST_PUSH="$GIT_DIR_/hooks/post-push"

test -x "$PRE_PUSH" &&
    exec "$PRE_PUSH" "$BRANCH" "$@"

git push "$@"

test $? -eq 0 && test -x "$POST_PUSH" &&
    exec "$POST_PUSH" "$BRANCH" "$@"

Saved as git-push-wh somewhere in your PATH, it can then be called as git push-wh if you want to push with hooks.

回答3:

This type of hook is not supported by Git. It falls outside the valid reasons for a Git hook as given by Git's maintainer.

The introductory remark in the above linked message speaks almost directly to your case:

I do not particularly like hooks that act after an operation is initiated locally and act solely on local data. This is maybe because I still consider git tools building blocks suitable for higher level scripting more than other people do.

P.S. A “Single Push” Hint

There are too many caveats for a full explanation, but if you can figure it all out you should be able to deal with the details.

An extra pushurl to a local repo with an “alternates” objects store could give you a low overhead way to locally execute a push hook. But really, the effort is much more than git push upstream && update-web-server (maybe in a shell alias, git alias, or script).

回答4:

I recently came across the same issue. I wanted a hook so that a push from my git submodule would commit the new submodule reference in the 'superproject'.

As Chris mentioned, the best way is to just use a git alias, like this:

$ git config alias.xpush '!git push $1 $2 && update-server.sh'
# (remember the backslash before the ! if your shell requires it)

This adds the following to your .git/config file:

[alias]
  xpush = !git push $1 $2 && update-server.sh

And so now, if you type:

$ git xpush

your changes will be pushed, and then update-server.sh will be executed.

I'm using a function for this:

current_branch() {
    local ref=$(git symbolic-ref HEAD 2> /dev/null) || return
    echo ${ref#refs/heads/}
}

gp() {
    local post_push="$(git rev-parse --git-dir)/hooks/post-push"
    git push "$@" && {
        [[ -x "$post_push" ]] && "$post_push" "$(current_branch)" "$@"
    }
}
compdef _git gp=git-push

The compdef part is for ZSH.
