stop leaking lock structs in some simple cases Now that it's safe to declare a "struct lock_file" on the stack, we can do so (and avoid an intentional leak). These leaks were found by running t0000 and t0001 under valgrind (though certainly other similar leaks exist and just don't happen to be exercised by those tests). Initializing the lock_file's inner tempfile with NULL is not strictly necessary in these cases, but it's a good practice to model. It means that if we were to call a function like rollback_lock_file() on a lock that was never taken in the first place, it becomes a quiet noop (rather than undefined behavior). Likewise, it's always safe to rollback_lock_file() on a file that has already been committed or deleted, since that operation is a noop on an inactive lockfile (and that's why the case in config.c can drop the "if (lock)" check as we move away from using a pointer).

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-.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://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.
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):
