Make the "n" variable added inc553c72eed(run-command: add an asynchronous parallel child processor, 2015-12-15) a "size_t". As we'll see in a subsequent commit we do pass "0" here, but never "jobs < 0". We could have made it an "unsigned int", but as we're having to change this let's not leave another case in the codebase where a size_t and "unsigned int" size differ on some platforms. In this case it's likely to never matter, but it's easier to not need to worry about it. After this and preceding changes: make run-command.o DEVOPTS=extra-all CFLAGS=-Wno-unused-parameter Only has one (and new) -Wsigned-compare warning relevant to a comparison about our "n" or "{nr,max}_processes": About using our "n" (size_t) in the same expression as online_cpus() (int). A subsequent commit will adjust & deal with online_cpus() and that warning. The only users of the "n" parameter are: * builtin/fetch.c: defaults to 1, reads from the "fetch.parallel" config. As seen in the code that parses the config added ind54dea77db(fetch: let --jobs=<n> parallelize --multiple, too, 2019-10-05) will die if the git_config_int() return value is < 0. It will however pass us n = 0, as we'll see in a subsequent commit. * submodule.c: defaults to 1, reads from "submodule.fetchJobs" config. Read via code originally added ina028a1930c(fetching submodules: respect `submodule.fetchJobs` config option, 2016-02-29). It now piggy-backs on the the submodule.fetchJobs code and validation added inf20e7c1ea2(submodule: remove submodule.fetchjobs from submodule-config parsing, 2017-08-02). Like builtin/fetch.c it will die if the git_config_int() return value is < 0, but like builtin/fetch.c it will pass us n = 0. * builtin/submodule--helper.c: defaults to 1. Read via code originally added in2335b870fa(submodule update: expose parallelism to the user, 2016-02-29). Sincef20e7c1ea2(submodule: remove submodule.fetchjobs from submodule-config parsing, 2017-08-02) it shares a config parser and semantics with the submodule.c caller. * hook.c: hardcoded to 1, see96e7225b31(hook: add 'run' subcommand, 2021-12-22). * t/helper/test-run-command.c: can be -1 after parsing the arguments, but will then be overridden to online_cpus() before passing it to this API.

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
