Merge branch 'ps/odb-pluggable-housekeeping' into next Object database housekeeping in 'git gc' and 'git maintenance' has been refactored to be pluggable. The files-backend-specific logic, including incremental and geometric repacking as well as object pruning, has been moved out of the command implementation and into the files object database source, enabling future alternative object database backends to implement their own housekeeping services. * ps/odb-pluggable-housekeeping: odb: make optimizations pluggable builtin/gc: fix signedness issues in ODB-related functionality builtin/gc: refactor ODB optimizations to operate on "files" source builtin/gc: introduce `odb_optimize_required()` builtin/gc: move geometric repacking into `odb_optimize()` builtin/gc: introduce object database optimization options builtin/gc: inline config values specific to the "files" backend builtin/gc: make repack arguments self-contained builtin/gc: extract object database optimizations into separate function builtin/gc: move worktree and rerere tasks before object optimizations odb: run "pre-auto-gc" hook for all maintenance tasks t7900: simplify how we check for maintenance tasks
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.adoc to get started, then see Documentation/giteveryday.adoc for a useful minimum set of commands, and Documentation/git-<commandname>.adoc 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.adoc (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):
