The `--trust-exit-code` option for git-diff-tool(1) was introduced via2b52123fcf(difftool: add support for --trust-exit-code, 2014-10-26). When set, it makes us return the exit code of the invoked diff tool when diffing multiple files. This patch didn't change the code path where `--dir-diff` was passed because we already returned the exit code of the diff tool unconditionally in that case. This was changed a month later viac41d3fedd8(difftool--helper: add explicit exit statement, 2014-11-20), where an explicit `exit 0` was added to the end of git-difftool--helper.sh. While the stated intent of that commit was merely a cleanup, it had the consequence that we now to ignore the exit code of the diff tool when `--dir-diff` was set. This change in behaviour is thus very likely an unintended side effect of this patch. Now there are two ways to fix this: - We can either restore the original behaviour, which unconditionally returned the exit code of the diffing tool when `--dir-diff` is passed. - Or we can make the `--dir-diff` case respect the `--trust-exit-code` flag. The fact that we have been ignoring exit codes for 7 years by now makes me rather lean towards the latter option. Furthermore, respecting the flag in one case but not the other would needlessly make the user interface more complex. Fix the bug so that we also honor `--trust-exit-code` for dir diffs and adjust the documentation accordingly.

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 and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://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
