3 # An example hook script to verify what is about to be pushed. Called by "git
|
|
|
4 # push" after it has checked the remote status, but before anything has been
|
|
|
5 # pushed. If this script exits with a non-zero status nothing will be pushed.
|
|
|
6 #
|
|
|
7 # This hook is called with the following parameters:
|
|
|
8 #
|
|
|
9 # $1 -- Name of the remote to which the push is being done
|
|
|
10 # $2 -- URL to which the push is being done
|
|
|
11 #
|
|
|
12 # If pushing without using a named remote those arguments will be equal.
|
|
|
13 #
|
|
|
14 # Information about the commits which are being pushed is supplied as lines to
|
|
|
15 # the standard input in the form:
|
|
|
16 #
|
|
|
17 # <local ref> <local sha1> <remote ref> <remote sha1>
|
|
|
18 #
|
|
|
19 # This sample shows how to prevent push of commits where the log message starts
|
|
|
20 # with "WIP" (work in progress).
