We support the new credential and authtype fields, but we lack a way to indicate to a credential helper that we'd like them to be used. Without some sort of indication, the credential helper doesn't know if it should try to provide us a username and password, or a pre-encoded credential. For example, the helper might prefer a more restricted Bearer token if pre-encoded credentials are possible, but might have to fall back to more general username and password if not. Let's provide a simple way to indicate whether Git (or, for that matter, the helper) is capable of understanding the authtype and credential fields. We send this capability when we generate a request, and the other side may reply to indicate to us that it does, too. For now, don't enable sending capabilities for the HTTP code. In a future commit, we'll introduce appropriate handling for that code, which requires more in-depth work. The logic for determining whether a capability is supported may seem complex, but it is not. At each stage, we emit the capability to the following stage if all preceding stages have declared it. Thus, if the caller to git credential fill didn't declare it, then we won't send it to the helper, and if fill's caller did send but the helper doesn't understand it, then we won't send it on in the response. If we're an internal user, then we know about all capabilities and will request them. For "git credential approve" and "git credential reject", we set the helper capability before calling the helper, since we assume that the input we're getting from the external program comes from a previous call to "git credential fill", and thus we'll invoke send a capability to the helper if and only if we got one from the standard input, which is the correct behavior.

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.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
