gix fails to recognize bare repos that have an index file as bare if they are not named `<repo>.git`

[eatradish]

Current behavior 😯

My step:

gix clone --bare https://github.com/AOSC-Dev/oma oma-bare
mkdir oma-not-bare
cd oma-not-bare
git init
git --git-dir ../oma-bare --work-tree . checkout -f e8f56b5
cd ../oma-bare
gix fetch origin +refs/heads/*:refs/heads/*

gix return error:

Error: './.git/objects' wasn't a directory

Expected behavior 🤔

git success to run:

$ git fetch origin +refs/heads/*:refs/heads/*
from https://github.com/AOSC-Dev/oma
 * [new branch]          cratify-oma -> cratify-oma
$ echo $?
0

Thanks for reporting! I can reproduce the issue and noticed that what matters here is the fact that a bare repository isn't called repo.git, but repo-bare in this case the actual problem is the index file present in the bare repo and the fact that it has been renamed to not <repo>.git.

Apparently it's fooled into thinking the repo is indeed having a working tree, and goes off the rails from there.

This is fixed in main, please try again to validate. Thank you.

I could verify it with gix and the example provided here isn't reproducible anymore. Thanks again for sharing this case.

Hi, I seem to have another problem after upgrading gitoxide to 0.29.0:

$ gix fetch origin +refs/heads/*:refs/heads/*
Error: Cannot find a remote for unborn branch
