When calling `git init --separate-git-dir=<new-path>` on a preexisting repository, we move the Git directory of that repository to the new path specified by the user. If there are worktrees present in the repository, we need to repair the worktrees so that their gitlinks point to the new location of the repository. This repair logic will load repositories via `get_worktrees()`, which will enumerate up and initialize all worktrees. Part of initialization is logic that we resolve their respective worktree HEADs, even though that information may not actually be needed in the end by all callers. Although not a problem presently with the file-based reference backend, it will become a problem with the upcoming reftable backend. In the context of git-init(1) we do not have a fully-initialized repository set up via `setup_git_directory()` or friends. Consequently, we do not know about the repository format when `repair_worktrees()` is called, and properly setting up all parts of the repositroy in `init_db()` before we try to repair worktrees is not an easy task. With the introduction of the reftable backend, we would ultimately try to look up the worktree HEADs before we have figured out the reference format, which does not work. We do not require the worktree HEADs at all to repair worktrees. So let's fix this issue by skipping over the step that reads them.

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 and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). The mailing list archives are available at https://lore.kernel.org/git/, https://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
