# git pre-push hook script to:
|
|
# 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.
|
|
#
|
|
# The following sample script was used as starting point:
|
|
# https://github.com/git/git/blob/master/templates/hooks--pre-push.sample
