Jeff King cc8fcd1e1a clone: use remote branch if it matches default HEAD Usually clone tries to use the same local HEAD as the remote (unless the user has given --branch explicitly). Even if the remote HEAD is detached or unborn, we can detect those situations with modern versions of Git. If the remote is too old to support the "unborn" extension (or it has been disabled via config), then we can't know the name of the remote's unborn HEAD, and we fall back whatever the local default branch name is configured to be. But that leads to one weird corner case. It's rare because it needs a number of factors: - the remote has an unborn HEAD - the remote is too old to support "unborn", or has disabled it - the remote has another branch "foo" - the local default branch name is "foo" In that case you end up with a local clone on an unborn "foo" branch, disconnected completely from the remote's "foo". This is rare in practice, but the result is quite confusing. When choosing "foo", we can double check whether the remote has such a name, and if so, start our local "foo" at the same spot, rather than making it unborn. Note that this causes a test failure in t5605, which is cloning from a bundle that doesn't contain HEAD (so it behaves like a remote that doesn't support "unborn"), but has a single "main" branch. That test expects that we end up in the weird "unborn main" case, where we don't actually check out the remote branch of the same name. Even though we have to update the test, this seems like an argument in favor of this patch: checking out main is what I'd expect from such a bundle. So this patch updates the test for the new behavior and adds an adjacent one that checks what the original was going for: if there's no HEAD and the bundle _doesn't_ have a branch that matches our local default name, then we end up with nothing checked out.

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/, 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
