Subject: [BUG] Wrong worktree path when using multiple worktree
Message-ID: <5638E79E.10407@morey-chaisemartin.com>

Hi,

There seem to be an issue with the path computed for a worktree when multiple worktree were created (using git worktree)
In my Setup, I have 3 repos:
A/repo (main One)
A/repo-patches (worktree, using branch dev)
B/repo (worktree, using branch next)

I'm working in A/repo-patches an run:
$ git checkout next
fatal: 'next' is already checked out at 'A/repo-patches'

Which is partially true but not completely.
I looked a bit in the code and found that the issue comes from here (get_linked_worktree):
    if (!strbuf_strip_suffix(&worktree_path, "/.git")) {
        strbuf_reset(&worktree_path);
        strbuf_addstr(&worktree_path, absolute_path("."));
        strbuf_strip_suffix(&worktree_path, "/.");
    }
Because it wrongfully assumes that I am in the linked worktree.
I checked in the .git/worktree files and couldn't see anything that actually points to where the repo are setup.
