mlanln · 2023-04-11T03:07:21Z

Description of the bug

I am trying out git-branchless in a repo at work. git sl works fine but write commands like git record, git amend, and git reword crash.

Expected behavior

No error

Hi @mlanln, sorry to hear that this is happening. Another user also reported this on Discord, but unfortunately we were unable to find a solution; they ended up recloning the repo. My assumption is that this is a bug in libgit2, but I'm not sure.

mlanln · 2023-04-14T06:57:10Z

Darn, I was hoping it was fixable. I get the same error on a newly git inited repo so recloning doesn't change anything.

arxanas · 2023-04-14T07:16:00Z

@mlanln can you try with a version of Git earlier than 2.40? Maybe something about the index format changed and libgit2 hasn't upgraded to handle it yet.

mlanln · 2023-04-14T08:18:44Z

Bingo! I downgraded to git version 2.39.2 and all of those commands are working now. Thanks!!

arxanas · 2023-04-14T19:28:53Z

@mlanln Thanks for confirming. I'll leave the issue open in case others run into the same problem. I also very recently updated our version of git2 (in f25babf); if you have time, could you try with that version of the code and see if the problem still occurs with Git v2.40? (See Manual testing.)

auscompgeek · 2023-04-17T07:04:33Z

I'm still seeing this error with git v2.40.0 with f25babf. Here's me trying to git move -b my-branch:

arxanas · 2023-04-18T02:15:01Z

It looks like it's this issue in libgit2: libgit2/libgit2#6531

You can follow the workaround here:

workaround is to disable the offending option git config --local index.skipHash false. then you have to clear your index and restage all your changes so that the index gets built with the option disabled.

I expect we'll have to wait for libgit2 to fix it and for the changes to propagate downstream.

chriskrycho · 2023-07-12T17:36:42Z

Bonus note: you may not be setting index.skipHash directly. If you set feature.manyFiles = true, that will have the same effect (it implicitly enables index.skipHash, I believe).

halostatue · 2024-02-20T15:24:07Z

This has been fixed in libgit2/libgit2#6738, so it should be in the next release of libgit2 (1.7.3 or later).

robinst · 2024-04-09T02:49:24Z

Looks like the fix for this was released with libgit2 v1.8.0 (released 3 weeks ago): https://github.com/libgit2/libgit2/releases/tag/v1.8.0

Now this is blocked on the rust bindings:

libgit2: Bump to v1.8.1 rust-lang/git2-rs#1032

injust · 2024-08-06T09:01:27Z

I think this is unblocked now? rust-lang/git2-rs#1032 was released in https://github.com/rust-lang/git2-rs/releases/tag/git2-0.19.0.

robinst · 2024-10-03T11:25:09Z

FYI this PR bumped git2 to 0.19.0 which includes the fix for this issue:

fix: allow deleting a branch when config entries contain multivars #1393

You can install from git using cargo install --git https://github.com/arxanas/git-branchless git-branchless or wait for the next release to get the fix for this.
