- # 1) prevent "fixup!" and "squash!" commit from ending up in master, release-*
- # or maint-*
- # 2) Disallow pushing branches other than master, release-*
- # and maint-* to origin (e.g. gitweb.torproject.org)
- #
- # To install this script, copy it into .git/hooks/pre-push path in your
- # local copy of git repository. Make sure it has permission to execute.
- # Furthermore, make sure that TOR_UPSTREAM_REMOTE_NAME environment
- # variable is set to local name of git remote that corresponds to upstream
- # repository on e.g. git.torproject.org.

- # https://github.com/git/git/blob/master/templates/hooks--pre-push.sample
- # Are you adding a new check to the git hooks?
- # - Common checks belong in the pre-commit hook
- # - Push-only checks belong in the pre-push hook
