File quilt-refresh-check.diff of Package quilt

From: Jan Blunck <jblunck@suse.de>
Subject: Add quilt_refresh_check() hook

This patch adds a hook function that is called during refresh. At that point
in time a user specified script can be called. If the hook function signals
no error the refresh is permitted.

Here is an example from my ~/.quiltrc:

function quilt_refresh_check () {
        local oldpatch=$1
        local newpatch=$2

        # Run scripts/checkpatch.pl
        if [ -f scripts/checkpatch.pl ]
        then
                perl -w scripts/checkpatch.pl --no-tree $newpatch | \
                    grep -v "has no obvious"
        fi

        # Check if somebody from SUSE signed of this patch
        if ! grep -Eiqe "^(From|Signed-off-by|Acked-by):.*@(suse\.(de|com|cz)|novell.com)\>" $newpatch; then
                local ACKED_BY=$(git var GIT_COMMITTER_IDENT | \
                        sed -e 's/>.*/>/')
                local LAST_SIGNED_OFF=$(cat $newpatch | \
                        sed -ne '/^Signed-off-by: /p' | sed -ne '$p')
                local tmpfile=$(gen_tempfile)
                
                if [ -n "$LAST_SIGNED_OFF" ] ; then
                        cat_file $newpatch | sed -e "/^$LAST_SIGNED_OFF$/a\Acked-by: $ACKED_BY" > $tmpfile
                else
                        cat_file $newpatch | sed -e "/^---$/i\Acked-by: $ACKED_BY" > $tmpfile
                fi
                cat_to_new_file $newpatch < $tmpfile
                rm -f $tmpfile
        fi

        return 0
}
