Fix a segfault in the --set-upstream option added in24bc1a1292(pull, fetch: add --set-upstream option, 2019-08-19) added in v2.24.0. The code added there did not do the same checking we do for "git branch" itself since8efb8899cf(branch: segfault fixes and validation, 2013-02-23), which in turn fixed the same sort of segfault I'm fixing now in "git branch --set-upstream-to", see6183d826ba(branch: introduce --set-upstream-to, 2012-08-20). The warning message I'm adding here is an amalgamation of the error added for "git branch" in8efb8899cf, and the error output install_branch_config() itself emits, i.e. it trims "refs/heads/" from the name and says "branch X on remote", not "branch refs/heads/X on remote". I think it would make more sense to simply die() here, but in the other checks for --set-upstream added in24bc1a1292we issue a warning() instead. Let's do the same here for consistency for now. There was an earlier submitted alternate way of fixing this in [1], due to that patch breaking threading with the original report at [2] I didn't notice it before authoring this version. I think the more detailed warning message here is better, and we should also have tests for this behavior. The --no-rebase option to "git pull" is needed as of the recently merged7d0daf3f12(Merge branch 'en/pull-conflicting-options', 2021-08-30). 1. https://lore.kernel.org/git/20210706162238.575988-1-clemens@endorphin.org/ 2. https://lore.kernel.org/git/CAG6gW_uHhfNiHGQDgGmb1byMqBA7xa8kuH1mP-wAPEe5Tmi2Ew@mail.gmail.com/ Reported-by: Clemens Fruhwirth <clemens@endorphin.org> Reported-by: Jan Pokorný <poki@fnusa.cz> 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
