Untracked cache was originally designed to only work with "--untracked-files=normal", and is bypassed when "--untracked-files=all" is requested, but this causes performance issues for UI tooling that wants to see "all" on a frequent basis. On the other hand, the conditions that altogether prevented applicability to the "all" mode no longer seem to apply, after several major refactors in recent years; this possibility was discussed in 81153d02-8e7a-be59-e709-e90cd5906f3a@jeffhostetler.com and CABPp-BFiwzzUgiTj_zu+vF5x20L0=1cf25cHwk7KZQj2YkVzXw@mail.gmail.com, and somewhat confirmed experimentally by several users using a version of this patch to use untracked cache with -uall for about a year. When 'git status' runs without using the untracked cache, on a large repo, on windows, with fsmonitor, it can run very slowly. This can make GUIs that need to use "-uall" (and therefore currently bypass untracked cache) unusable when fsmonitor is enabled, on such large repos. To partially address this, align the supported directory flags for the stored untracked cache data with the git config. If a user specifies an '--untracked-files=' commandline parameter that does not align with their 'status.showuntrackedfiles' config value, then the untracked cache will be ignored - as it is for other unsupported situations like when a pathspec is specified. If the previously stored flags no longer match the current configuration, but the currently-applicable flags do match the current configuration, then discard the previously stored untracked cache data. For most users there will be no change in behavior. Users who need '--untracked-files=all' to perform well will now have the option of setting "status.showuntrackedfiles" to "all" for better / more consistent performance. Users who need '--untracked-files=all' to perform well for their tooling AND prefer to avoid the verbosity of "all" when running git status explicitly without options... are out of luck for now (no change). Users who have the "status.showuntrackedfiles" config set to "all" and yet frequently explicitly call 'git status --untracked-files=normal' (and use the untracked cache) are the only ones who will be disadvantaged by this change. Their "--untracked-files=normal" calls will, after this change, no longer use the untracked cache. Signed-off-by: Tao Klerks <tao@klerks.biz> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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 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 with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). 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
