This commit extends the functionality of `git gc` by adding a new option, `--expire-to=<dir>`. Previously, this feature was implemented in 91badeba32 (builtin/repack.c: implement `--expire-to` for storing pruned objects, 2022-10-24), which allowing users to specify a directory where unreachable and expired cruft packs are stored during garbage collection. However, users had to run `git repack --cruft --expire-to=<dir>` followed by `git prune` to achieve similar results within `git gc`. By introducing `--expire-to=<dir>` directly into `git gc`, we simplify the process for users who wish to manage their repository's cleanup more efficiently. This change involves passing the `--expire-to=<dir>` parameter through to `git repack`, making it easier for users to set up a backup location for cruft packs that will be pruned. Due to the original `git gc --prune=now` deleting all unreachable objects by passing the `-a` parameter to git repack. With the addition of the `--cruft` and `--expire-to` options, it is necessary to modify this default behavior: instead of deleting these unreachable objects, they should be merged into a cruft pack and collected in a specified directory. Therefore, we do not pass `-a` to the repack command but instead pass `--cruft`, `--expire-to`, and `--cruft-expiration=now` to repack.

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
