Re: Bug: All git operations fail when .git contains a non-existent gitdir

The easiest way to reproduce it is this:

$ mkdir test
$ cd test
$ echo "gitdir: /foo/bar" > .git
$ git ls-remote https://github.com/torvalds/linux

We happen to use overlay mounts in our build system in a way that maps
a git submodule from one place to another so that its "gitdir" is
invalid and then attempt a `git ls-remote` from that location which
unexpectedly fails.  But the above reproduces the problem well enough.

Tom

What did you do before the bug happened? (Steps to reproduce your issue)

Add a git submodule to a git repository.
Overlay-mount that submodule to another place in the filesystem.
Attempt any git operation in the overlay-mounted path.

I'm not sure about what you mean by an overlay-mount operation.  Can you
provide some specific commands that we can run at a shell that reproduce
the issue?
