(Updated according to the latest test code to make it easier to read)

It seems that AlternateFS doesn't work with git's clone --shared when the origin is also a "shared" one. For example:

• There is a repo /tmp/repo-origin

• Then "clone --shared" to /tmp/repo-clone1

• Then "clone --shared" from "clone1" to /tmp/repo-clone2

• Trying to set altRepoPath to /tmp/repo-origin or /tmp/repo-clone1

• If I use osfs.New(altRepoPath, osfs.WithChrootOS())

  • then func (d *DotGit) Alternates() changes the path to ../repo-clone1/objects or objects, which doesn't exist, then Alternates returns error.

• If I use osfs.New(altRepoPath, osfs.WithBoundOS())

  • then func (d *DotGit) Alternates() tries to use path /tmp/repo-clone1/objects, which doesn't exist, then Alternates returns error.

The only working approach is: AlternativeFS: osfs.New("/")
