Derrick Stolee 96cc8ab531 sparse-checkout: use hashmaps for cone patterns The parent and recursive patterns allowed by the "cone mode" option in sparse-checkout are restrictive enough that we can avoid using the regex parsing. Everything is based on prefix matches, so we can use hashsets to store the prefixes from the sparse-checkout file. When checking a path, we can strip path entries from the path and check the hashset for an exact match. As a test, I created a cone-mode sparse-checkout file for the Linux repository that actually includes every file. This was constructed by taking every folder in the Linux repo and creating the pattern pairs here: /$folder/ !/$folder/*/ This resulted in a sparse-checkout file sith 8,296 patterns. Running 'git read-tree -mu HEAD' on this file had the following performance: core.sparseCheckout=false: 0.21 s (0.00 s) core.sparseCheckout=true: 3.75 s (3.50 s) core.sparseCheckoutCone=true: 0.23 s (0.01 s) The times in parentheses above correspond to the time spent in the first clear_ce_flags() call, according to the trace2 performance traces. While this example is contrived, it demonstrates how these patterns can slow the sparse-checkout feature.

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://public-inbox.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
