The sample hook explicitly sets IFS to SP and nothing else so that the "read" used in the per-ref while loop that iterates over "<localref> SP <localsha1> SP <remoteref> SP <remotesha>" records, where we know refs and sha1s will not have SPs, would split them correctly. While this is not wrong per-se, it is not necessary; because we know these fields do not contain HT or LF, either, we can simply leave IFS the default. This will also prevent those who cut and paste from this sample from getting bitten when they write things in the per-ref loop that need splitting with the default $IFS (e.g. use $(git rev-list ...) to produce one-record-per-line output).

# An example 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 sha1> <remote ref> <remote sha1>
|
|
#
|
|
# This sample shows how to prevent push of commits where the log message starts
|
|
# with "WIP" (work in progress).
