Hello, I am running into an issue where "git bundle create" doesn't always produce the same bundle, provided the exact same arguments and the exact same repo. Where it gets tricky is that: - I cannot reproduce the issue with random repos from Github (tried with ~10 repos and 30 bundles per repo); - I cannot reproduce the issue with the same OS and git version on different hardware ; - I can reproduce the issue on colleagues' workstation (environment is identical down to the hardware, see below). Environment: - GNU/Linux 5.3.0-24-generic Ubuntu 19.10 x86_64 ; - git version 2.20.1 ; - Intel Xeon Silver 4114 CPU @ 2.20GHz × 20 ; - 4 × Hynix HMA81GR7CJR8N-VK 8GB DDR4-2666 ECC. I have put together a bash PoC [1]. And there are some example output in the comments (consistent [2], inconsistent [3]). [1] https://gist.github.com/alct/05cc9a2b4657d51669c96cb22cd5c4a6 [2] https://gist.github.com/alct/05cc9a2b4657d51669c96cb22cd5c4a6#gistcomment-3130206 [3] https://gist.github.com/alct/05cc9a2b4657d51669c96cb22cd5c4a6#gistcomment-3130213 I cannot share the affected repos but I can run any diagnostic tool against them. Would you have any clue on what could produce such behavior? Best, A.L.
