multi-pack-index: prepare for 'expire' subcommand The multi-pack-index tracks objects in a collection of pack-files. Only one copy of each object is indexed, using the modified time of the pack-files to determine tie-breakers. It is possible to have a pack-file with no referenced objects because all objects have a duplicate in a newer pack-file. Introduce a new 'expire' subcommand to the multi-pack-index builtin. This subcommand will delete these unused pack-files and rewrite the multi-pack-index to no longer refer to those files. More details about the specifics will follow as the method is implemented. Add a test that verifies the 'expire' subcommand is correctly wired, but will still be valid when the verb is implemented. Specifically, create a set of packs that should all have referenced objects and should not be removed during an 'expire' operation. The packs are created carefully to ensure they have a specific order when sorted by size. This will be important in a later test.

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-.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://public-inbox.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):
