# Usage: Copy this file to your repository's .git/hooks directory. Name it
# "pre-push" and set the executable bit.
#
# This hook aborts git push when the log message of any commits to be pushed
# starts with "WIP" (work in progress) or "stash", if the remote ref begins
# with "refs/for/". This prevents incomplete/unwanted commits from being
# pushed to Gerrit instances.
#
# When pushing to Gerrit, this hook also runs a Gradle build similar to
# Gerrit's presubmit, to help catch errors locally and reduce churn on CLs.
#
# Remaining comments are copied from .git/hooks/pre-push.sample.
#
# An example hook script to verify what is about to be pushed. Called by "git
# push" after it has checked the remote status, but before anything has been
# pushed. If this script exits with a non-zero status nothing will be pushed.
#
# This hook is called with the following parameters:
#
# $1 -- Name of the remote to which the push is being done
# $2 -- URL to which the push is being done
#
# If pushing without using a named remote those arguments will be equal.
#
# Information about the commits which are being pushed is supplied as lines to
# the standard input in the form:
#
# <local ref> <local sha1> <remote ref> <remote sha1>
