sequencer, stash: fix running from worktree subdir In commits bc3ae46b42 ("rebase: do not attempt to remove startup_info->original_cwd", 2021-12-09) and 0fce211ccc ("stash: do not attempt to remove startup_info->original_cwd", 2021-12-09), we wanted to allow the subprocess to know which directory the parent process was running from, so that the subprocess could protect it. However... When run from a non-main worktree, setup_git_directory() will note that the discovered git directory (/PATH/TO/.git/worktree/non-main-worktree) does not match DEFAULT_GIT_DIR_ENVIRONMENT (see setup_discovered_git_dir()), and decide to set GIT_DIR in the environment. This matters because... Whenever git is run with the GIT_DIR environment variable set, and GIT_WORK_TREE not set, it presumes that '.' is the working tree. So... This combination results in the subcommand being very confused about the working tree. Fix it by also setting the GIT_WORK_TREE environment variable along with setting cmd.dir. A possibly more involved fix we could consider for later would be to make setup.c set GIT_WORK_TREE whenever (a) it discovers both the git directory and the working tree and (b) it decides to set GIT_DIR in the environment. I did not attempt that here as such would be too big of a change for a 2.35.1 release.

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):
