I don't run a hook, but I have a separate script which does checks like
that. I've pulled out the Signed-off-by check into a script below, which
might work for you, or at least give you something to start from.
cheers
#!/bin/bash
function check_sob_by_committer
{
local commit=$1
git rev-parse --verify ${commit}^2 > /dev/null 2>&1
if [[ $? -eq 0 ]]; then
# It has at least 2 parents, ie. it's a merge
# We don't sign off merges, so we're done
return
fi
committer=$(git log -1 --format='%cn <%ce>' $commit)
git log -1 --format=%b $commit | grep "Signed-off-by: $committer" > /dev/null
if [[ $? -ne 0 ]]; then
echo " Not SOB committer '$committer'"
return 1
fi
return 0
}
check_sob_by_committer $1
exit $?
