Ævar Arnfjörð Bjarmason 16235e3b14 object-file: free(*contents) only in read_loose_object() caller In the preceding commit a free() of uninitialized memory regression in `96e41f58fe` (fsck: report invalid object type-path combinations, 2021-10-01) was fixed, but we'd still have an issue with leaking memory from fsck_loose(). Let's fix that issue too. That issue was introduced in my `31deb28f5e` (fsck: don't hard die on invalid object types, 2021-10-01). It can be reproduced under SANITIZE=leak with the test I added in `093fffdfbe` (fsck tests: add test for fsck-ing an unknown type, 2021-10-01): ./t1450-fsck.sh --run=84 -vixd In some sense it's not a problem, we lost the same amount of memory in terms of things malloc'd and not free'd. It just moved from the "still reachable" to "definitely lost" column in valgrind(1) nomenclature[1], since we'd have die()'d before. But now that we don't hard die() anymore in the library let's properly free() it. Doing so makes this code much easier to follow, since we'll now have one function owning the freeing of the "contents" variable, not two. For context on that memory management pattern the read_loose_object() function was added in `f6371f9210` (sha1_file: add read_loose_object() function, 2017-01-13) and subsequently used in `c68b489e56` (fsck: parse loose object paths directly, 2017-01-13). The pattern of it being the task of both sides to free() the memory has been there in this form since its inception. 1. https://valgrind.org/docs/manual/mc-manual.html#mc-manual.leaks Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>		2021-11-11 13:40:43 -08:00

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). 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
