The repo_get_default_remote() function in submodule--helper currently tries to figure out the proper remote name to use for a submodule based on a few factors. First, it tries to find the remote for the currently checked out branch. This works if the submodule is configured to checkout to a branch instead of a detached HEAD state. In the detached HEAD state, the code calls back to using "origin", on the assumption that this is the default remote name. Some users may change this, such as by setting clone.defaultRemoteName, or by changing the remote name manually within the submodule repository. As a first step to improving this situation, refactor to reuse the logic from remotes_remote_for_branch(). This function uses the remote from the branch if it has one. If it doesn't then it checks to see if there is exactly one remote. It uses this remote first before attempting to fall back to "origin". To allow using this helper function, introduce a repo_default_remote() helper to remote.c which takes a repository structure. This helper will load the remote configuration and get the "HEAD" branch. Then it will call remotes_remote_for_branch to find the default remote. Replace calls of repo_get_default_remote() with the calls to this new function. To maintain consistency with the existing callers, continue copying the returned string with xstrdup. This isn't a perfect solution for users who change remote names, but it should help in cases where the remote name is changed but users haven't added any additional remotes.

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
