I applied this patch instead of mine, and added the Makefile define
Harder to trace, as it is not issuing error messages, but could this
success^Wfailure be related?
/pro/3gl/LINUX/git-1.5.4.rc5 103 > cat t/t5701-clone-local.sh.err
* ok 1: preparing origin repository
* ok 2: local clone without .git suffix
* ok 3: local clone with .git suffix
* ok 4: local clone from x
* FAIL 5: local clone from x.git that does not exist
cd "$D" &&
if git clone -l -s x.git z
then
echo "Oops, should have failed"
false
else
echo happy
fi
* ok 6: With -no-hardlinks, local will make a copy
* ok 7: Even without -l, local will make a hardlink
* failed 1 among 7 test(s)
Any hints in where to start digging?
