Not able to detect branch from Git post-receive hook

git hook git-post-receive
jsleeuw picture jsleeuw · May 12, 2011 · Viewed 7.6k times · Source

I've got a post receive hook setup on the remote repo that tries to determine the branch name of the incoming push as follows:

$branch = `git rev-parse --abbrev-ref HEAD`

What i'm finding, though, is that no matter what branch I push from my $branch variable gets set with 'master'.

Any ideas?

The post-receive hook gets the same data as the pre-receive and not as arguments, but from stdin. The following is sent for all refs:

oldRev (space) newRev (space) refName (Line feed)

You could parse out the ref name with this bash script:

while read oldrev newrev ref
do
    echo "$ref"
done
