How to get a list of incoming commits on git push for a new branch in a hook

Question

I\'m writing a pre-receive hook to do some validation before accepting commits on the push. It works fine with existing branches since I use following git command to get a list

Answer 1

The following helped in my case. I personally think it's very simple.

OLD_REV=$2
NEW_REV=$3

if [ $OLD_REV == "0000000000000000000000000000000000000000" ]; then
    OLD_REV=$(git merge-base master $NEW_REV)
fi;

git diff --name-only $OLD_REV $NEW_REV
