travis-ci: build with the right compiler Our 'Makefile' hardcodes the compiler to build Git as 'CC = cc'. This CC variable can be overridden from the command line, i.e. 'make CC=gcc-X.Y' will build with that particular GCC version, but not from the environment, i.e. 'CC=gcc-X.Y make' will still build with whatever 'cc' happens to be on the platform. Our build jobs on Travis CI are badly affected by this. In the build matrix we have dedicated build jobs to build Git with GCC and Clang both on Linux and macOS from the very beginning (522354d70f (Add Travis CI support, 2015-11-27)). Alas, this never really worked as supposed to, because Travis CI specifies the compiler for those build jobs as 'export CC=gcc' and 'export CC=clang' (which works fine for projects built with './configure && make'). Consequently, our 'linux-clang' build job has always used GCC, because that's where 'cc' points at in Travis CI's Linux images, while the 'osx-gcc' build job has always used Clang. Furthermore, 37fa4b3c78 (travis-ci: run gcc-8 on linux-gcc jobs, 2018-05-19) added an 'export CC=gcc-8' in an attempt to build with a more modern compiler, but to no avail. Set MAKEFLAGS with CC based on the $CC environment variable, so 'make' will run the "right" compiler. The Xcode 10.1 macOS image on Travis CI already contains the gcc@8 package from Homebrew, but we have to 'brew link' it first to be able to use it. So with this patch our build jobs will build Git with the following compiler versions: linux-clang: clang version 5.0.0 (tags/RELEASE_500/final) linux-gcc: gcc-8 (Ubuntu 8.1.0-5ubuntu1~14.04) 8.1.0 osx-clang: Apple LLVM version 10.0.0 (clang-1000.11.45.5) osx-gcc: gcc-8 (Homebrew GCC 8.2.0) 8.2.0 GETTEXT_POISON: gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4 Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.
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):
