The old perl git-add--interactive.perl script used the color.diff config option to decide whether to color diffs (and if not set, it fell back to the value of color.ui via git-config's --get-colorbool option). When we switched to the builtin version, this was lost: we respect only color.ui. So for example: git -c color.diff=false add -p would color the diff, even when it should not. The culprit is this line in add-interactive.c's parse_diff(): if (want_color_fd(1, -1)) That "-1" means "no config has been set", which causes it to fall back to the color.ui setting. We should instead be passing the value of color.diff. But the problem is that we never even parse that config option! Instead the builtin interactive code parses only the value of color.interactive, which is used for prompts and other messages. One could perhaps argue that this should cover interactive diff coloring, too, but historically it did not. The perl script treated color.interactive and color.diff separately. So we should grab the values for both, keeping separate fields in our add_i_state variable, rather than a single use_color field. We also load individual color slots (e.g., color.interactive.prompt), leaving them as the empty string when color is disabled. This happens via the init_color() helper in add-interactive, which checks that use_color field. Now that there are two such fields, we need to pass the appropriate one for each color. The colors are mostly easy to divide up; color.interactive.* follows color.interactive, and color.diff.* follows color.diff. But the "reset" color is tricky. It is used for both types of coloring, but the two can be configured independently. So we introduce two separate reset colors, and use each in the appropriate spot. There are two new tests. The first enables interactive prompt colors but disables color.diff. We should see a colored prompt but not a colored diff, showing that we are now respecting color.diff (and not color.interactive or color.ui). The second does the opposite. We disable color.interactive but turn on color.diff with a custom fragment color. When we split a hunk, the interactive code has to re-color the hunk header, which lets us check that we correctly loaded the color.diff.frag config based on color.diff, not color.interactive.

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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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
