Follow-up the change in459b8d22e5(tests: do not borrow from COPYING and README from the real source, 2015-02-15) by not shipping a full copy of older versions of the top-level "COPYING" and "README" files. The tests that use them just need the small blurb at the top of "COPYING" as test data, or mock data that's dissimilar. Let's provide that with a "COPYING_test_data" function instead. We're not replacing this with some other generic test data (e.g. "lorum ipsum") because these tests require test file header to be the old "COPYING" file. See e.g. "t4003-diff-rename-1.sh" which changes the file, and then does full "test_cmp" comparisons on the resulting "git diff" output. This change only changes tests that used the "lib-diff.sh" library, but splits up what they need into a new "lib-diff-data.sh". A subsequent commit will change related tests that were missed in459b8d22e5. For the test in "t4008-diff-break-rewrite.sh" the "README" file can go away in favor of echoing the line "some dissimilar content" to a file in the one test that needed it. The point of that test is to start with files "A" and "B", and then have A be more similar to the state of "B" than to its old version (by copying over the content from the "COPYING" file). Just comparing the pre-image of "some dissimilar content" and later a munged version of the "COPYING" output serves that purpose. While we're at it get rid of a stray "echo $tree" debugging line added in15d061b435([PATCH] Fix the way diffcore-rename records unremoved source., 2005-05-27), and stop calling "hash-object" to get the hash of an object we've just added to the index. We can instead extract that information from the index itself with "rev-parse". Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@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 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
