Hi,
It appears that the last test in t9151-svn-mergeinfo.sh:
test_expect_failure 'everything got merged in the end' '
unmerged=$(git rev-list --all --not master) &&
[ -z "$unmerged" ]
'
reports "known breakage" or "breakage vanished" seemingly at random:
$ while true; do (cd t && sh t9151-svn-mergeinfo.sh | \
grep -q vanished && printf "f" || printf "b"); done
bbbffffbbffbffbbbffbfffbbbffffffffbffbbbfbbffffffbbfbfff
I would guess that it might not be the test itself that is unreliable,
but rather the svn setup done prior, looking at test logs:
(cd t && mkdir -p logs; i=0; \
while true; do sh t9151-svn-mergeinfo.sh --verbose 2>&1 | tee logs/cur \
| grep -q vanished && \
(printf "f" && mv logs/cur logs/fixed-"$i") || \
(printf "b" && mv logs/cur logs/broken-"$i"); \
i=$((i+1)); done)
bbffbff
the only consistent difference between broken and fixed seems to be in
the svn setup stage and more specifically the bit below, with r44
becoming different SHA1s in "broken" and "fixed" imports:
--- broken-0 2014-02-05 23:40:21.412967698 +0100
+++ fixed-2 2014-02-05 23:40:44.441536583 +0100

Does anyone who is more familiar with the test know what's going on
here? Is there any way to fix it, or should the test maybe be disabled
completely for the time being?
