David Turner a831c06a2b gc: ignore old gc.log files A server can end up in a state where there are lots of unreferenced loose objects (say, because many users are doing a bunch of rebasing and pushing their rebased branches). Running "git gc --auto" in this state would cause a gc.log file to be created, preventing future auto gcs, causing pack files to pile up. Since many git operations are O(n) in the number of pack files, this would lead to poor performance. Git should never get itself into a state where it refuses to do any maintenance, just because at some point some piece of the maintenance didn't make progress. Teach Git to ignore gc.log files which are older than (by default) one day old, which can be tweaked via the gc.logExpiry configuration variable. That way, these pack files will get cleaned up, if necessary, at least once per day. And operators who find a need for more-frequent gcs can adjust gc.logExpiry to meet their needs. There is also some cleanup: a successful manual gc, or a warning-free auto gc with an old log file, will remove any old gc.log files. It might still happen that manual intervention is required (e.g. because the repo is corrupt), but at the very least it won't be because Git is too dumb to try again.

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 http://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):

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
