The pathname of a repository comes from getcwd() and it could be a path aliased via symbolic links, e.g., the real directory may be /home/u/repository but a symbolic link /home/u/repo may point at it, and the clone request may come as "git clone file:///home/u/repo/" A request to check if /home/u/repository is safe would be rejected if the safe.directory configuration allows /home/u/repo/ but not its alias /home/u/repository/. Normalize the paths configured for the safe.directory configuration variable before comparing them with the path being checked. Two and a half things to note, compared to the previous step to normalize the actual path of the suspected repository, are: - A configured safe.directory may be coming from .gitignore in the home directory that may be shared across machines. The path meant to match with an entry may not necessarily exist on all of such machines, so not being able to convert them to real path on this machine is *not* a condition that is worthy of warning. Hence, we ignore a path that cannot be converted to a real path. - A configured safe.directory is essentially a random string that user throws at us, written completely unrelated to the directory the current process happens to be in. Hence it makes little sense to give a non-absolute path. Hence we ignore any non-absolute paths, except for ".". - The safe.directory set to "." was once advertised on the list as a valid workaround for the regression caused by the overly tight safe.directory check introduced in 2.45.1; we treat it to mean "if we are at the top level of a repository, it is OK".

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 to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). 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
