Jeff King 8f416f65c9 shorten_unambiguous_ref(): use NUM_REV_PARSE_RULES constant 
The ref_rev_parse_rules[] array is terminated with a NULL entry, and we
count it and store the result in the local nr_rules variable. But we
don't need to do so; since the array is a constant, we can compute its
size directly. The original code probably didn't do that because it was
written as part of for-each-ref, and saw the array only as a pointer. It
was migrated in 7c2b3029df (make get_short_ref a public function,
2009-04-07) and could have been updated then, but that subtlety was not
noticed.

We even have a constant that represents this value already, courtesy of
60650a48c0 (remote: make refspec follow the same disambiguation rule as
local refs, 2018-08-01), though again, nobody noticed at the time that
it could be used here, too.

The current count-up isn't a big deal, as we need to preprocess that
array anyway. But it will become more cumbersome as we refactor the
shortening code. So let's get rid of it and just use the constant
everywhere.

Note that there are two things here that aren't just simple text
replacements:

  1. We also use nr_rules to see if a previous call has initialized the
     static pre-processing variables. We can just use the scanf_fmts
     pointer to do the same thing, as it is non-NULL only after we've
     done that initialization.

  2. If nr_rules is zero after we've counted it up, we bail from the
     function. This code is unreachable, though, as the set of rules is
     hard-coded and non-empty. And that becomes even more apparent now
     that we are using the constant. So we can drop this conditional
     completely (and ironically, the code would have the same output if
     it _did_ trigger, as we'd simply skip the loop entirely and return
     the whole refname).

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
