2.22 issue across samba

2.22 issue across samba

[Gary Poli]

Hello,
	I'm running git for windows installed locally. Windows 10 Pro version 1903 OS Build 18362.239. I have a repository on a UNIX machine running AIX 7.1 TL4 SP2. I use SAMBA 3.0.23d to mount the drive for use. I upgraded to git 2.22 and am having issues. Even starting from a fresh clone of the repo, the head immediately detaches. After a few commands like status or branch it stops recognizing the repo altogether. I suspect it is having trouble reading or writing to itself; perhaps the index is getting corrupted. I reverted to git 2.14 and I'm working fine again. I've got my system admin looking into updating both AIX and SAMBA, but I thought I would report the issue here as well. Let me know if you need anything else from me. Thanks.

I don't have any particular thoughts on what might be the cause here.
But if:

  - you can reliably produce the problem on git 2.22 but not on git 2.14

and

  - you are able to build Git from source

then it would be useful to use git-bisect between those versions to find the
commit introducing the problem.
