The function `init_db()` is responsible for creating the on-disk
directory structure required for a Git repository. It is used by both
git-init(1) and git-clone(1), and because their expected behaviour is
different we support a couple of flags:
- The `QUIET` flag controls whether the command is quiet or not. For
git-init(1) this is user-controllable, whereas for git-clone(1)
we're always quiet.
- The `EXIST_OK` flag controls whether a preexisting repository is
okay or not. For git-init(1) it is, for git-clone(1) it's not.
- The `SKIP_REFDB` flag controls whether the reference database should
already be created or not. For git-init(1) we do, but for
git-clone(1) we don't because it does not yet know about the default
branch and about the remote object hash.
Furthermore, we're about to add another divergence in behaviour, where
we have to also skip creation of the object database in git-clone(1).
This is becoming quite cumbersome though.
Instead of introducing another flag, start to split up concerns of the
function so that we never create the reference or object database. This
becomes the responsibility of the caller, which is thus free to defer
their creation to a later point in time. This lets us get rid of most of
the divergent behaviour:
- We don't need the `SKIP_REFDB` and a potential `SKIP_ODB` flags
anymore.
- We don't need the `QUIET` flag anymore, as nothing prints output
except for the final status message that tells the user that the
repository has been (re)initialized. But as this message is specific
to git-init(1), we can easily move it there.
The only piece of information we still have to convey is whether or not
reinitialization of a preexisting repository is okay. This is handled by
a new `reinit_ok` pointer that, if non-`NULL`, indicates that it is okay
to reinitialize the repository. Furthermore, the pointer will be written
to to indicate whether the repository was reinitialized or not, which we
need in git-init(1) to print the correct initialization message.
With these refactorings, `init_db()` is named quite misleadingly though,
as we don't create any of the reference or object databases anymore.
Rename it to `create_repository()`.

README.md
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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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
