Error when adding a local repo from a mapped network drive on Windows

Operating System

Windows

Distribution Method

msi (Windows)

Describe the issue

An error occurs when attempting to add a local repo from a mapped network drive on Windows.

The error message is misleading, because there is an actual error in the logs, but the error displayed to the user is "Must be a Git repository" (which the directory actually is)

How to reproduce

• clone a repository in a directory accessible over the network; in my case, this is a directory in my local Linux VM hosted on WSL2
• map a Windows drive to the network directory (e.g. U:)
• attempt to add the repo to GitButler by browsing to the mapped drive and the respective directory

Expected behavior

Repo is added successfully

Thanks so much for reporting!

It appears that gitoxide was unable to obtain ownership information from a mapped network drive. Maybe git2 would succeed here, but gix seems to be first in line. It seemingly does things similarly. Git itself also seems to do the same, so I wonder if git works in the mapped location?

Maybe this is at least tangentially related to GitoxideLabs/gitoxide#1429, and I'd hope that @EliahKagan could also take a look. Seeing how similar the implementations are I wonder if Git for Windows patches in something special there.

[andrew-rosca]

Yes, git appears to work on the mapped drive from Windows.

Thank you, this gives me hope it can be fixed, with the 'how' being publicly available at least in the Git for Windows repository.
