If you pass a bogus argument to %(refname), you may end up with a message like this: $ git for-each-ref --format='%(refname:foo)' fatal: unrecognized %(refname:foo) argument: foo which is confusing. It should just say: fatal: unrecognized %(refname) argument: foo which is clearer, and is consistent with most other atom parsers. Those other parsers do not have the same problem because they pass the atom name from a string literal in the parser function. But because the parser for %(refname) also handles %(upstream) and %(push), it instead uses atom->name, which includes the arguments. The oid atom parser which handles %(tree), %(parent), etc suffers from the same problem. It seems like the cleanest fix would be for atom->name to be _just_ the name, since there's already a separate "args" field. But since that field is also used for other things, we can't change it easily (e.g., it's how we find things in the used_atoms array, and clearly %(refname) and %(refname:short) are not the same thing). Instead, we'll teach our error_bad_arg() function to stop at the first ":". This is a little hacky, as we're effectively re-parsing the name, but the format is simple enough to do this as a one-liner, and this localizes the change to the error-reporting code. We'll give the same treatment to err_no_arg(). None of its callers use this atom->name trick, but it's worth future-proofing it while we're here.

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
