The proper hash algorithm and ref storage format that will be used for a newly initialized repository will be figured out in `init_db()` via `validate_hash_algorithm()` and `validate_ref_storage_format()`. Until now though, we never set up the hash algorithm or ref storage format of `the_repository` accordingly. There are only two callsites of `init_db()`, one in git-init(1) and one in git-clone(1). The former function doesn't care for the formats to be set up properly because it never access the repository after calling the function in the first place. For git-clone(1) it's a different story though, as we call `init_db()` before listing remote refs. While we do indeed have the wrong hash function in `the_repository` when `init_db()` sets up a non-default object format for the repository, it never mattered because we adjust the hash after learning about the remote's hash function via the listed refs. So the current state is correct for the hash algo, but it's not for the ref storage format because git-clone(1) wouldn't know to set it up properly. But instead of adjusting only the `ref_storage_format`, set both the hash algo and the ref storage format so that `the_repository` is in the correct state when `init_db()` exits. This is fine as we will adjust the hash later on anyway and makes it easier to reason about the end state of `the_repository`.

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
