CVE-2023-40267 Hand Cherry-Pick ca965ec#diff-f50d635cf31b095a03b42fc1a73681a9c4025bbeb58b81e72588ba37e00cff87R355
Fix format string problems in Python2 Try to fix some errors Fix importing of pathlib Fixes to get GitPython to work on Python2 Backport Pathlib2 to Pathlib This is probably more correct since it won't drag in tests we haven't tried before Fix errors caused by git_unpack_args More changes to try and deal with errors Fix problem with test not running
