We have description on "per worktree ref", but "worktree" is not described in the glossary. We do have "working tree", though. Casually put, a "working tree" is what your editor and compiler interacts with. "worktree" is a mechanism to allow one or more "working tree"s to be attached to a repository and used to check out different commits and branches independently, which includes not just a "working tree" but also repository metadata like HEAD, the index to support simultaneous use of them. Historically, we used these terms interchangeably but we have been trying to use "working tree" when we mean it, instead of "worktree". Most of the existing references to "working tree" in the glossary do refer primarily to the working tree portion, except for one that said refs like HEAD and refs/bisect/* are per "working tree", but it is more precise to say they are per "worktree". Signed-off-by: Junio C Hamano <gitster@xxxxxxxxx> --- * Mostly unchanged from the version in the original discussion https://lore.kernel.org/git/xmqqo83hatm1.fsf@gitster.g/ except that we now mention that pseudorefs are also per worktree. One thing that makes me worried somewhat is what I did not touch, namely, how pseudo refs are defined. I know MERGE_HEAD is very special and it may be impossible to coax it into refs API for writing, so the text there makes sense for it, but there are other all-caps-and-directly-under-dot-git-directory files like ORIG_HEAD and CHERRY_PICK_HEAD that are written using the refs API, so the description would have to be updated there.
