Since update-deployment is run on the host being deployed to and only has access to a recent clone of the git repository, it doesn't necessarily have the old refs available for reverts. (imported from commit 3652f58a7b165c805822bf6d8a4f0792c629e28e)

# Humbug's post-receive hook. There is a symlink
|
|
# from /srv/git/humbug.git/hooks/post-receive
|
|
# to ~humbug/humbug/tools/post-receive
|
|
# on git.humbughq.com. So to deploy changes to this script, run
|
|
#
|
|
# ssh humbug@git.humbughq.com 'cd humbug; git pull'
|
|
#
|
|
# To send the Humbug 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 Humbug configuration; for the moment those are
|
|
# bots/githook-post-receive and bots/humbug_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
