Patrick Steinhardt 2121a76d71 git-compat-util: introduce macros to disable "-Wsign-compare" warnings When compiling with DEVELOPER=YesPlease, we explicitly disable the "-Wsign-compare" warning. This is mostly because our code base is full of cases where we don't bother at all whether something should be signed or unsigned, and enabling the warning would thus cause tons of warnings to pop up. Unfortunately, disabling this warning also masks real issues. There have been multiple CVEs in the Git project that would have been flagged by this warning (e.g. CVE-2022-39260, CVE-2022-41903 and several fixes in the vicinity of these CVEs). Furthermore, the final audit report by X41 D-Sec, who are the ones who have discovered some of the CVEs, hinted that it might be a good idea to become more strict in this context. Now simply enabling the warning globally does not fly due to the stated reason above that we simply have too many sites where we use the wrong integer types. Instead, introduce a new set of macros that allow us to mark a file as being free of warnings with "-Wsign-compare". The mechanism is similar to what we do with `USE_THE_REPOSITORY_VARIABLE`: every file that is not marked with `DISABLE_SIGN_COMPARE_WARNINGS` will be compiled with those warnings enabled. These new markings will be wired up in the subsequent commits. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>		2024-12-06 20:20:01 +09:00

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
