`test_run_` in test-lib.sh "lints" the body of a test by sending it down a `sed chainlint.sed | grep` pipeline; this happens once for each test run by a test script. Although this pipeline may seem relatively cheap in isolation, it can become expensive when invoked 26800+ times by `make test`, once for each test run, despite the existence of only 16500+ test definitions across all tests scripts. This difference in the number of tests defined in the scripts (16500+) and the number of tests actually run by `make test` (26800+) is explained by the fact that some test scripts run a very large number of small tests, all driven by a series of functions/loops which fill in the test bodies. This means that certain test definitions are being linted repeatedly (tens or hundreds of times) unnecessarily. To avoid such unnecessary work,2d86a96220(t: avoid sed-based chain-linting in some expensive cases, 2021-05-13) added an optimization hack which allows individual scripts to manually suppress the unnecessary repeated linting of the same test definition. However, unlike chainlint.sed which checks a test body as the test is run, chainlint.pl checks each test definition just once, no matter how many times the test is run, thus the sort of optimization hack introduced by2d86a96220is no longer needed and can be retired. Therefore, revert2d86a96220. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> 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
