On Windows, the default line endings are denoted by a Carriage Return byte followed by a Line Feed byte, while Linux and MacOSX use a single Line Feed byte to denote a line ending. To help with this situation, Git introduced several mechanisms over the last decade, most prominently the `core.autocrlf` setting. Sometimes, however, a single setting is incorrect, e.g. when certain files in the source code are to be consumed by software that can handle only LF line endings, while other files can use whatever is appropriate for the current platform. To allow for that, Git added the `eol` option to its .gitattributes handling, expecting every user of Git to mark their source code appropriately. Bash assumes that line-endings of scripts are denoted by a single Line Feed byte. Therefore, shell scripts in Git's source code are one example where that `eol=lf` option is *required*. When generating common-cmds.h, the Unix tools we use generally operate on the assumption that input and output deliminate their lines using LF-only line endings. Consequently, they would happily copy the CR byte verbatim into the strings in common-cmds.h, which in turn makes the C preprocessor barf (that interprets them as MacOS-style line endings). Therefore, we have to mark the input files as LF-only: command-list.txt and Documentation/git-*.txt. Quite a bit belatedly, this patch brings Git's own source code in line with those expectations by setting those attributes to allow for a correct build even when core.autocrlf=true. This patch can be validated even on Linux, by using this cadence: git config core.autocrlf true rm .git/index && git stash make -j15 DEVELOPER=1 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Reviewed-by: Jonathan Nieder <jrnieder@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-.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
