WSL & Worktree issue : Not a git repositiory

[OdysseusOperator]

Git is set up, just like this: https://learn.microsoft.com/en-us/windows/wsl/tutorials/wsl-git

I am using WSL Ubuntu 24.04. Windows and Linux both have Git in Version 2.47.1 This error doesn't appear on Windows, just from WSL.

---

Steps to reproduce: (Works with all repos i think) Open Wsl. make a dir to work in and cd into it. git clone https://github.com/routerdieb/java11TxtTimebox main cd main git worktree add ../test123 cd .. cd test123 git pull (or git push doesnt matter here)

 git push --set-upstream origin test123
fatal: not a git repository: /mnt/d/code2dash_wsl/main/.git/worktrees/test123

The issue arises due to mixing UNIX and Win32 executable using absolute paths. The native (Linux) Git creates WSL/*NIX notation (/mnt/d/code2dash_wsl/…). GCM (or its Git companion) in such a scenario only knows Win32 paths (D:/code2dash_wsl/…).

While the Exception is (just) bad error handling, the underlying issue persists. You can mitigate this by using a relative path references in /mnt/d/code2dash_wsl/test123/.git: gitdir: ../main/.git/worktrees/test123 That is also the way Git submodules handle references to their respective Git directory.

The subsequent (forward) resolution to the origin Git directory is also using relative paths (See contents of /mnt/d/code2dash_wsl/main/.git/worktrees/test123/commondir). Backward resolution of the worktree folder could still become problematic without further adjustment. But GCM luckily does not care about that. :smile:

Starting with Git v2.48 there is now an option to use relative paths when using worktrees.
