Is there a way to lock a branch in GIT

Question

I have an idea of locking a repository from users pushing files into it by having a lock script in the GIT update hook since the push can only recognize the userid as arguments and not the branches. So i can lock the entire repo which is just locking a directory.

Is there a way to lock a specific branch in GIT?

Or is there a way an Update Hook can identify from which branch the user is pushing and to which branch the code is pushed?

Answer 1

The branch being pushed to is the first parameter to the update hook. If you want to lock the branch myfeature for pushing, this code (placed in hooks/update) will do it:

#!/bin/sh
# lock the myfeature branch for pushing
refname="$1"

if [[ $refname == "refs/heads/myfeature" ]]
then
    echo "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    echo "You cannot push to myfeature! It's locked"
    echo "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    exit 1
fi
exit 0
