Thanks for your fix. I'll have a look at whether I can include a 32 bit job into GitLab CI for improved test coverage here so that it does not fall on you to fix up things like this going forward. Overall, CI has been in pretty rough shape recently. Besides the mentioned failures there's also been the issue with flaky tests: - t5616-partial-clone regularly fails on macOS. [1] This seems like a race condition or to me: error: unable to open .git/objects/pack/pack-029d08823bd8a8eab510ad6ac75c823cfd3ed31e.pack: No such file or directory fatal: unable to rename temporary file to '.git/objects/pack/pack-029d08823bd8a8eab510ad6ac75c823cfd3ed31e.pack' fatal: could not finish pack-objects to repack local links fatal: index-pack failed error: last command exited with $?=128 not ok 18 - fetch --refetch triggers repacking - The leak-checking jobs fail quite regularly in t0003 with something that feels like either a race caused by a leak or an issue with the sanitizer itself [2]: ==git==17055==ERROR: LeakSanitizer: detected memory leaks Direct leak of 32 byte(s) in 1 object(s) allocated from: #0 0x7aa0d03c7713 in realloc ../../../../src/libsanitizer/lsan/lsan_interceptors.cpp:98 #1 0x7aa0d0221f69 in pthread_getattr_np (/lib/x86_64-linux-gnu/libc.so.6+0x9df69) (BuildId: 6d64b17fbac799e68da7ebd9985ddf9b5cb375e6) #2 0x7aa0d03d9544 in __sanitizer::GetThreadStackTopAndBottom(bool, unsigned long*, unsigned long*) ../../../../src/libsanitizer/sanitizer_common/sanitizer_linux_libcdep.cpp:150 #3 0x7aa0d03d96fa in __sanitizer::GetThreadStackAndTls(bool, unsigned long*, unsigned long*, unsigned long*, unsigned long*) ../../../../src/libsanitizer/sanitizer_common/sanitizer_linux_libcdep.cpp:614 #4 0x7aa0d03cb2b9 in __lsan::ThreadStart(unsigned int, unsigned long long, __sanitizer::ThreadType) ../../../../src/libsanitizer/lsan/lsan_posix.cpp:53 #5 0x7aa0d03c756a in ThreadStartFunc<false> ../../../../src/libsanitizer/lsan/lsan_interceptors.cpp:431 #6 0x7aa0d0220a93 (/lib/x86_64-linux-gnu/libc.so.6+0x9ca93) (BuildId: 6d64b17fbac799e68da7ebd9985ddf9b5cb375e6) #7 0x7aa0d02adc3b (/lib/x86_64-linux-gnu/libc.so.6+0x129c3b) (BuildId: 6d64b17fbac799e68da7ebd9985ddf9b5cb375e6) DEDUP_TOKEN: ___interceptor_realloc--pthread_getattr_np--__sanitizer::GetThreadStackTopAndBottom(bool, unsigned long*, unsigned long*)--__sanitizer::GetThreadStackAndTls(bool, unsigned long*, unsigned long*, unsigned long*, unsigned long*)--__lsan::ThreadStart(unsigned int, unsigned long long, __sanitizer::ThreadType)--ThreadStartFunc<false>---- SUMMARY: LeakSanitizer: 32 byte(s) leaked in 1 allocation(s). - Windows has been quite flaky since adding it to GitLab CI. No idea whether it's the same for GitHub Actions. The thing is, the less reliable it becomes the more likely it is that people are simply going to ignore its results. I'll try to have a look at some of the problems on Monday. Patrick [1]: https://gitlab.com/git-scm/git/-/jobs/8671168627 [2]: https://gitlab.com/git-scm/git/-/jobs/8671168849
