I`m yet another beginner with both Git hooks and Bash scripting, but
I`ve managed to patch something up that might give you an idea, just
drop it inside your "pre-receive" hook file:
while read oldrev newrev
do
for commit in $(git rev-list --reverse $oldrev..$newrev)
do
for file in $(git diff-tree --no-commit-id --name-only
-r $commit)
do
echo "$(git show $commit:$file)" >&1
done
done
done
exit 1
This should reject any push attempt, returning back *content* of each
changed file for each new commit.
Feel free to adapt as needed, like processing/checking file content
instead of sending it over, allowing or rejecting the push
accordingly, and also handling corner cases (for example, "oldrev"
value of 0000... in case of a new ref creation).
I guess there might be better ways (comments welcome), but this
should at least get you going... and I`ve learned something new as
well ;)

Buga
