# git pre-push hook script to:
|
|
# 0) Call the pre-commit hook, if it is available
|
|
# 1) prevent "fixup!" and "squash!" commit from ending up in main, release-*
|
|
# or maint-*
|
|
# 2) Disallow pushing branches other than main, 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.
