Lately our GCC macOS build job on Travis CI has been erroring out while installing dependencies with: +brew link gcc@8 Error: No such keg: /usr/local/Cellar/gcc@8 The command "ci/install-dependencies.sh" failed and exited with 1 during . Now, while gcc@8 is still pre-installed (but not linked) and would be perfectly usable in the Travis CI macOS image we use [1], it's at version 8.2. However, when installing dependencies we first explicitly run 'brew update', which spends over two minutes to update itself and information about the available packages, and it learns about GCC 8.3. After that point gcc@8 exclusively refers to v8.3, and, unfortunately, 'brew' is just too dumb to be able to do anything with the still installed 8.2 package, and the subsequent 'brew link gcc@8' fails. (Even 'brew uninstall gcc@8' fails with the same error!) Don't run 'brew update' to keep the already installed GCC 8.2 'brew link'-able. Note that in addition we have to 'export HOMEBREW_NO_AUTO_UPDATE=1' first, because 'brew' is so very helpful that it would implicitly run update for us on the next 'brew install <pkg>' otherwise. Disabling 'brew update' has additional benefits: - It shaves off 2-3mins from the ~4mins currently spent on installing dependencies, and the macOS build jobs have always been prone to exceeding the time limit on Travis CI. - Our builds won't suddenly break because of the occasional Homebrew breakages [2]. The drawback is that we'll be stuck with slightly older versions of the packages that we install via Homebrew (Git-LFS 2.5.2 and Perforce 2018.1; they are currently at 2.7.2 and 2019.1, respectively). We might want to reconsider this decision as time goes on and/or switch to a more recent macOS image as they become available. [1] |

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.
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
