Ævar Arnfjörð Bjarmason e87de7cab4 grep: un-break building with PCRE < 8.32 Amend my change earlier in this series ("grep: add support for the PCRE v1 JIT API", 2017-04-11) to un-break the build on PCRE v1 versions earlier than 8.32. The JIT support was added in version 8.20 released on 2011-10-21, but it wasn't until 8.32 released on 2012-11-30 that the fast code path to use the JIT via pcre_jit_exec() was added[1] (see also [2]). This means that versions 8.20 through 8.31 could still use the JIT, but supporting it on those versions would add to the already verbose macro soup around JIT support it, and I don't expect that the use-case of compiling a brand new git against a 5 year old PCRE is particularly common, and if someone does that they can just get the existing pre-JIT slow codepath. So just take the easy way out and disable the JIT on any version older than 8.32. The reason this change isn't part of the initial change PCRE JIT support is to have a cleaner history showing which parts of the implementation are only used for ancient PCRE versions. This also makes it easier to revert this change if we ever decide to stop supporting those old versions. 1. http://www.pcre.org/original/changelog.txt ("28. Introducing a native interface for JIT.

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-.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.

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
