# Zulip's post-receive hook. There is a symlink
# from /home/git/repositories/eng/zulip.git/hooks/post-receive
# to ~zulip/zulip/tools/post-receive
# on git.zulip.net. So to deploy changes to this script, run
#
# ssh zulip@git.zulip.net 'cd zulip; git pull'
#
# To send the Zulip notices, this script calls out to our
# for-distribution git hook (under api/integrations/); since the git
# hook needs to be in the same directory as the configuration script
# for the git hook, this means that we need to have a shared directory
# containing (a symlink to) both the the for-distribution git hook and
# the Zulip configuration; for the moment those are
# bots/githook-post-receive and bots/zulip_git_config.py,
# respectively. We need the intermediate symlink because the git hook
# looks for its configuration in the directory that it sits in, and
# api/integrations/git/ has the example configuration.
#
#
# The "post-receive" script is run after receive-pack has accepted a pack
# and the repository has been updated. It is passed arguments in through
# stdin in the form
# <oldrev> <newrev> <refname>
# For example:
# aa453216d1b3e49e7f6f98441fa56946ddcd6a20 68f7abf4e6f922807889f52bc043ecd31b79f814 refs/heads/master
#
# see contrib/hooks/ for a sample
