nth_packed_object_oid(): use customary integer return Our nth_packed_object_sha1() function returns NULL for error. So when we wrapped it with nth_packed_object_oid(), we kept the same semantics. But it's a bit funny, because the caller actually passes in an out parameter, and the pointer we return is just that same struct they passed to us (or NULL). It's not too terrible, but it does make the interface a little non-idiomatic. Let's switch to our usual "0 for success, negative for error" return value. Most callers either don't check it, or are trivially converted. The one that requires the biggest change is actually improved, as we can ditch an extra aliased pointer variable. Since we are changing the interface in a subtle way that the compiler wouldn't catch, let's also change the name to catch any topics in flight. We can drop the 'o' and make it nth_packed_object_id(). That's slightly shorter, but also less redundant since the 'o' stands for "object" already. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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):
