Derrick Stolee cd94f82005 commit: integrate with sparse-index Update 'git commit' to allow using the sparse-index in memory without expanding to a full one. The only place that had an ensure_full_index() call was in cache_tree_update(). The recursive algorithm for update_one() was already updated in `2de37c536` (cache-tree: integrate with sparse directory entries, 2021-03-03) to handle sparse directory entries in the index. Most of this change involves testing different command-line options that allow specifying which on-disk changes should be included in the commit. This includes no options (only take currently-staged changes), -a (take all tracked changes), and --include (take a list of specific changes). To simplify testing that these options do not expand the index, update the test that previously verified that 'git status' does not expand the index with a helper method, ensure_not_expanded(). This allows 'git commit' to operate much faster when the sparse-checkout cone is much smaller than the full list of files at HEAD. Here are the relevant lines from p2000-sparse-operations.sh: Test HEAD~1 HEAD ---------------------------------------------------------------------------------- 2000.14: git commit -a -m A (full-v3) 0.35(0.26+0.06) 0.36(0.28+0.07) +2.9% 2000.15: git commit -a -m A (full-v4) 0.32(0.26+0.05) 0.34(0.28+0.06) +6.3% 2000.16: git commit -a -m A (sparse-v3) 0.63(0.59+0.06) 0.04(0.05+0.05) -93.7% 2000.17: git commit -a -m A (sparse-v4) 0.64(0.59+0.08) 0.04(0.04+0.04) -93.8% It is important to compare the full-index case to the sparse-index case, so the improvement for index version v4 is actually an 88% improvement in this synthetic example. In a real repository with over two million files at HEAD and 60,000 files in the sparse-checkout definition, the time for 'git commit -a' went from 2.61 seconds to 134ms. I compared this to the result if the index only contained the paths in the sparse-checkout definition and found the theoretical optimum to be 120ms, so the out-of-cone paths only add a 12% overhead.

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
