Makes complete sense now. I thought initially that the "no such file"
refered to the actual hooks script. I naively assumed my ssh
connection on sf.net gave me access to the actual git boxes (or maybe
it is executed from a chroot).
In any case rewriting the script in pure shell script (no bash either)
seems to work ok now (*).
However I am now being told that this script should rather go in the
update hooks...
(*)
read rev_old rev_new refname
ref_to_check="refs/heads/master"
if [ "$refname" == "$ref_to_check" ]
then
merge_bases=`git merge-base ${rev_old} ${rev_new}`
if [ "$merge_bases" != "$rev_old" ]
then
echo "Non fastward is disallowed"
exit 1
fi
# non-fast-forward case:
git rev-list --parents $merge_bases..$rev_new \
| while read x; do
set -- $x
if [ "$#" != "2" ]
then
echo "Multiple parents: $x";
exit 1
fi;
done
[ $? -ne 0 ] && exit 1
fi
exit 0
