When working on a large feature, it can be helpful to break that feature into multiple smaller parts that become reviewed in sequence. During development or during review, a change to one part of the feature could affect multiple of these parts. An interactive rebase can help adjust the multi-part "story" of the branch. However, if there are branches tracking the different parts of the feature, then rebasing the entire list of commits can create commits not reachable from those "sub branches". It can take a manual step to update those branches. Add a new --update-refs option to 'git rebase -i' that adds 'update-ref <ref>' steps to the todo file whenever a commit that is being rebased is decorated with that <ref>. At the very end, the rebase process updates all of the listed refs to the values stored during the rebase operation. Be sure to iterate after any squashing or fixups are placed. Update the branch only after those squashes and fixups are complete. This allows a --fixup commit at the tip of the feature to apply correctly to the sub branch, even if it is fixing up the most-recent commit in that part. This change update the documentation and builtin to accept the --update-refs option as well as updating the todo file with the 'update-ref' commands. Tests are added to ensure that these todo commands are added in the correct locations. This change does _not_ include the actual behavior of tracking the updated refs and writing the new ref values at the end of the rebase process. That is deferred to a later change.

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 with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). 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
