Local dependency specification with context formatting for NFS path breaks
I'm running a VM with VirtualBox to test out an application in Windows. The repository is mounted into the VM using NFS (VirtualBox mounts paths under //vboxsvr), and there is a local dependency that's in that NFS directory. The context formatting that works on native Linux or Windows breaks in this case, i.e.
dependencies = [
# ...
"foo @ {root:parent:uri}/foo", # This equates to: file:////vboxsvr/my_repo/foo
]
However, this works:
dependencies = [
# ...
"foo @ file://vboxsvr/my_repo/foo",
]
It seems like for the NFS path should only contain the first two path separators, and not the four that the uri context formatter adds.
This is a niche edge case. Would it be possible to detect if the path for a dependency is in a UNC path, i.e. is prefixed by //, and then the uri context formatter would only add the file: prefix.
My work around is to detect the VM, and set an env var and then do this:
dependencies = [
# ...
"foo @ {env:PROJ_URI_VM:{root:parent:uri}}/foo",
]
Setup:
- hatch 1.9.0
- python 3.11.7
- Windows 11 VM
Hey! I think rather than handling your edge case directly I should call os.path.normpath internally. Would that suffice?
@ofek I tested that out on my side and it didn't fix the issue (I made the changes in fs.py). This is quite a niche issue. I've run into bigger issues in that cmd.exe can't handle the UNC path anyway. I don't mind if we close the issue.
