sparse-checkout: update working directory in-process The sparse-checkout builtin used 'git read-tree -mu HEAD' to update the skip-worktree bits in the index and to update the working directory. This extra process is overly complex, and prone to failure. It also requires that we write our changes to the sparse-checkout file before trying to update the index. Remove this extra process call by creating a direct call to unpack_trees() in the same way 'git read-tree -mu HEAD' does. In addition, provide an in-memory list of patterns so we can avoid reading from the sparse-checkout file. This allows us to test a proposed change to the file before writing to it. An earlier version of this patch included a bug when the 'set' command failed due to the "Sparse checkout leaves no entry on working directory" error. It would not rollback the index.lock file, so the replay of the old sparse-checkout specification would fail. A test in t1091 now covers that scenario.

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). 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):
