Maybe this is just a flag to the ref traversal functions. True. Alternatively we could just view refs/worktree/* as if they are symbolic refs that point into refs/worktrees/$my_worktree/*, but that would imply making the latter always visible to all worktrees, which would hurt when people use it to interact with outside world (namely, refs in other people's private area should probably not be advertised). > As I understand it, we don't presently do many transactions that include > both pseudorefs or per-worktree refs and other refs.

We may be over-engineering with Michael's and even with the more simpler refs/worktree/* -> refs/worktrees/$mine/* fixed mapping; I tend to agree with you. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
