Replace a chunk of code in update_submodule() with an equivalent do_get_submodule_displaypath() invocation. This is already tested by t/t7406-submodule-update.sh:'submodule update --init --recursive from subdirectory', so no tests are added. The two are equivalent because: - Exactly one of recursive_prefix|prefix is non-NULL at a time; prefix is set at the superproject level, and recursive_prefix is set when recursing into submodules. There is also a BUG() statement in get_submodule_displaypath() that asserts that both cannot be non-NULL. - In get_submodule_displaypath(), get_super_prefix() always returns NULL because "--super-prefix" is never passed. Thus calling it is equivalent to calling do_get_submodule_displaypath() with super_prefix = NULL. Therefore: - When recursive_prefix is non-NULL, prefix is NULL, and thus get_submodule_displaypath() just returns prefixed_path. This is identical to calling do_get_submodule_displaypath() with super_prefix = recursive_prefix because the return value is still the concatenation of recursive_prefix + update_data->sm_path. - When prefix is non-NULL, prefixed_path = update_data->sm_path. Thus calling get_submodule_displaypath() with prefixed_path is equivalent to calling do_get_submodule_displaypath() with update_data->sm_path Signed-off-by: Glen Choo <chooglen@google.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 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
