The content of .git/worktrees/<id>/gitdir must be a path of the form "/path/to/worktree/.git". Any other content would be indicative of a corrupt "gitdir" file. To determine the path of the worktree itself one merely strips the "/.git" suffix, and this is indeed how the worktree path was determined from inception. However,5193490442(worktree: add a function to get worktree details, 2015-10-08) extended the path manipulation in a mysterious way. If it is unable to strip "/.git" from the path, then it instead reports the current working directory as the linked worktree's path: if (!strbuf_strip_suffix(&worktree_path, "/.git")) { strbuf_reset(&worktree_path); strbuf_add_absolute_path(&worktree_path, "."); strbuf_strip_suffix(&worktree_path, "/."); } This logic is clearly bogus; it can never be generally correct behavior. It materialized out of thin air in5193490442with neither explanation nor tests to illustrate a case in which it would be desirable. It's possible that this logic was introduced to somehow deal with a corrupt "gitdir" file, so that it returns _some_ sort of meaningful value, but returning the current working directory is not helpful. In fact, it is quite misleading (except in the one specific case when the current directory is the worktree whose "gitdir" entry is corrupt). Moreover, reporting the corrupt value to the user, rather than fibbing about it and hiding it outright, is more helpful since it may aid in diagnosing the problem. Therefore, drop this bogus path munging and restore the logic to the original behavior of merely stripping "/.git".

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
