# A hook script to verify what is about to be pushed. Called by "git push"
|
|
# after it has checked the remote status, but before anything has been pushed.
|
|
# If this script exits with a non-zero status nothing will be pushed.
|
|
#
|
|
# This hook is called with the following parameters:
|
|
#
|
|
# $1 -- Name of the remote to which the push is being done
|
|
# $2 -- URL to which the push is being done
|
|
#
|
|
# If pushing without using a named remote those arguments will be equal.
|
|
#
|
|
# Information about the commits which are being pushed is supplied as lines to
|
|
# the standard input in the form:
|
|
#
|
|
# <local ref> <local oid> <remote ref> <remote oid>
|
|
#
|
|
# To enable this hook, save or link this file at `.git/hooks/pre-push`.
|
|
#
|
|
# This prevents pushing of commits where the log message starts with "WIP" (work
|
|
# in progress) or "{fixup,squash}!" (Autosquash, see git-rebase(1)).
