Change the main() function to call "exit()" instead of ending with a "return" statement. The "exit()" function is our own wrapper that calls trace2_cmd_exit_fl() for us, from git-compat-util.h: #define exit(code) exit(trace2_cmd_exit_fl(__FILE__, __LINE__, (code))) That "exit()" wrapper has been in use ever sinceee4512ed48(trace2: create new combined trace facility, 2019-02-22). This changes nothing about how we "exit()", as we'd invoke "trace2_cmd_exit_fl()" in both cases due to the wrapper, this change makes it easier to reason about this code, as we're now always obviously relying on our "exit()" wrapper. There is already code immediately downstream of our "main()" which has a hard reliance on that, e.g. the various "exit()" calls downstream of "cmd_main()" in "git.c". We even had a comment in "t/helper/test-trace2.c" that seemed to be confused about how the "exit()" wrapper interacted with uses of "return", even though it was introduced in the same trace2 series ina15860dca3(trace2: t/helper/test-trace2, t0210.sh, t0211.sh, t0212.sh, 2019-02-22), after the aforementionedee4512ed48. Perhaps it pre-dated the "exit()" wrapper? This change makes the "trace2_cmd_exit()" macro orphaned, we now always use "trace2_cmd_exit_fl()" directly, but let's keep that simpler example in place. Even if we're unlikely to get another "main()" other than the one in our "common-main.c", there's some value in having the API documentation and example discuss a simpler version that doesn't require an "exit()" wrapper macro.

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). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. 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
