After 'git fetch <remote> <TAB>' our completion script offers refspecs that will fetch to a local branch with the same name as in the remote repository, e.g. 'master:master'. This also completes non-fast-forward refspecs, i.e. after a '+' prefix like '+master:master', and fully qualified refspecs, e.g. 'refs/heads/master:refs/heads/master'. However, it does not complete non-fast-forward fully qualified refspecs (or fully qualified refspecs following any other prefix, e.g. '--option=', though currently no git command supports such an option, but third party git commands might). These refspecs are listed by the __git_refs2() function, which is just a thin wrapper iterating over __git_refs()'s output, turning each listed ref into a refspec. Now, it's certainly possible to modify __git_refs2() and its callsite to pass an extra parameter containing only the ref part of the current word to be completed (to follow suit of the previous commit) to deal with prefixed fully qualified refspecs as well. Unfortunately, keeping the current behavior unchanged in the "no extra parameter" case brings in a bit of subtlety, which makes the resulting code ugly and compelled me to write a 8-line long comment in the proof of concept. Not good. However, since the callsite has to be modified for proper functioning anyway, we might as well leave __git_refs2() as is and introduce a new helper function without backwards compatibility concerns. Add the new function __git_complete_fetch_refspecs() that has all the necessary parameters to do the right thing in all cases mentioned above, including non-fast-forward fully qualified refspecs. This new function can also easier benefit from optimizations coming later in this patch series. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.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 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
