Ævar Arnfjörð Bjarmason 15c9649730 grep/log: remove hidden --debug and --grep-debug options 
Remove the hidden "grep --debug" and "log --grep-debug" options added
in 17bf35a3c7 (grep: teach --debug option to dump the parse tree,
2012-09-13).

At the time these options seem to have been intended to go along with
a documentation discussion and to help the author of relevant tests to
perform ad-hoc debugging on them[1].

Reasons to want this gone:

 1. They were never documented, and the only (rather trivial) use of
    them in our own codebase for testing is something I removed back
    in e01b4dab01 (grep: change non-ASCII -i test to stop using
    --debug, 2017-05-20).

 2. Googling around doesn't show any in-the-wild uses I could dig up,
    and on the Git ML the only mentions after the original discussion
    seem to have been when they came up in unrelated diff contexts, or
    that test commit of mine.

 3. An exception to that is c581e4a749 (grep: under --debug, show
    whether PCRE JIT is enabled, 2019-08-18) where we added the
    ability to dump out when PCREv2 has the JIT in effect.

    The combination of that and my earlier b65abcafc7 (grep: use PCRE
    v2 for optimized fixed-string search, 2019-07-01) means Git prints
    this out in its most common in-the-wild configuration:

        $ git log  --grep-debug --grep=foo --grep=bar --grep=baz --all-match
        pcre2_jit_on=1
        pcre2_jit_on=1
        pcre2_jit_on=1
        [all-match]
        (or
         pattern_body<body>foo
         (or
          pattern_body<body>bar
          pattern_body<body>baz
         )
        )

        $ git grep --debug \( -e foo --and -e bar \) --or -e baz
        pcre2_jit_on=1
        pcre2_jit_on=1
        pcre2_jit_on=1
        (or
         (and
          patternfoo
          patternbar
         )
         patternbaz
        )

I.e. for each pattern we're considering for the and/or/--all-match
etc. debugging we'll now diligently spew out another identical line
saying whether the PCREv2 JIT is on or not.

I think that nobody's complained about that rather glaringly obviously
bad output says something about how much this is used, i.e. it's
not.

The need for this debugging aid for the composed grep/log patterns
seems to have passed, and the desire to dump the JIT config seems to
have been another one-off around the time we had JIT-related issues on
the PCREv2 codepath. That the original author of this debugging
facility seemingly hasn't noticed the bad output since then[2] is
probably some indicator.

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
