Invalid data in index

[TrueWill]

On an M1 Mac, every time I use GitUp on any repository I get

invalid data in index - calculated checksum does not match expected

I can recreate this by creating a new repository with git init, then adding a single commit of an empty file, then opening GitUp.

Version 1.3.5 (1048)

git version 2.40.0

Mmm, I'm on an M1 Max and can't repro this. My specific setup is Ventura 13.3.1 (git version 2.39.2 (Apple Git-143)).

Did you explicitly install a custom version of git?

To be clear with my repro steps (in folder for git project):

1. git init
2. touch file
3. git add file
4. git commit -m "Test"
5. gitup (command line tool to open project in GitUp)

@lucasderraugh Yes, I'm using git installed through Homebrew. I'm on Ventura 13.3.1 as well.

Using your exact steps above I can reproduce the error.

However, if I explicitly use /usr/bin/git (git version 2.39.2 (Apple Git-143)) to create and update the repository then I do not get the error.

This appears to be an incompatibility with the current release of git.

I am seeing this too, with the latest gitup + git versions, making it entirely unusable. Is there a way to set the git version used by gitup?

[Cykelero]

Strange: I can't reproduce either, using GitUp 1.4.0 and Git 2.45.2.

This might be related to the new index.skipHash option, for which support was added to libgit2 only recently.

• Could you check if the option is set in the repo? (run git config index.skipHash; it might output nothing, or a boolean)
• If it is set, could you try turning it off for the repo (git config index.skipHash false), creating a new commit from the CLI, then checking the repo in GitUp again?

[FrancoisBlavoet]

Same setup ( GitUp 1.4.0 and Git 2.45.2.)

index.skipHash is not set for me. I have tried setting it to false, and it does seem to solve the issue!
