SZEDER Gábor a2f5a87626 rev-parse: add '--absolute-git-dir' option
The output of 'git rev-parse --git-dir' can be either a relative or an
absolute path, depending on whether the current working directory is
at the top of the worktree or the .git directory or not, or how the
path to the repository is specified via the '--git-dir=<path>' option
or the $GIT_DIR environment variable.  And if that output is a
relative path, then it is relative to the directory where any 'git
-C <path>' options might have led us.

This doesn't matter at all for regular scripts, because the git
wrapper automatically takes care of changing directories according to
the '-C <path>' options, and the scripts can then simply follow any
path returned by 'git rev-parse --git-dir', even if it's a relative
path.

Our Bash completion script, however, is unique in that it must run
directly in the user's interactive shell environment.  This means that
it's not executed through the git wrapper and would have to take care
of any '-C <path> options on its own, and it can't just change
directories as it pleases.  Consequently, adding support for taking
any '-C <path>' options on the command line into account during
completion turned out to be considerably more difficult, error prone
and required more subshells and git processes when it had to cope with
a relative path to the .git directory.

Help this rather special use case and teach 'git rev-parse' a new
'--absolute-git-dir' option which always outputs a canonicalized
absolute path to the .git directory, regardless of whether the path is
discovered automatically or is specified via $GIT_DIR or 'git
--git-dir=<path>'.

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 http://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
