get_main_ref_store: BUG() when outside a repository
If we don't have a repository, then we can't initialize the ref store. Prior to 64a741619d (refs: store the main ref store inside the repository struct, 2018-04-11), we'd try to access get_git_dir(), and outside a repository that would trigger a BUG(). After that commit, though, we directly use the_repository->git_dir; if it's NULL we'll just segfault. Let's catch this case and restore the BUG() behavior. Obviously we don't ever want to hit this code, but a BUG() is a lot more helpful than a segfault if we do. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
