sparse-index: create expand_index() This is the first change in a series to allow modifying the sparse-checkout pattern set without expanding a sparse index to a full one in the process. Here, we focus on the problem of expanding the pattern set through a command like 'git sparse-checkout add <path>' which needs to create new index entries for the paths now being written to the worktree. To achieve this, we need to be able to replace sparse directory entries with their contained files and subdirectories. Once this is complete, other code paths can discover those cache entries and write the corresponding files to disk before committing the index. We already have logic in ensure_full_index() that expands the index entries, so we will use that as our base. Create a new method, expand_index(), which takes a pattern list, but for now mostly ignores it. The current implementation is only correct when the pattern list is NULL as that does the same as ensure_full_index(). In fact, ensure_full_index() is converted to a shim over expand_index(). A future update will actually implement expand_index() to its full capabilities. For now, it is created and documented.

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):
