unpack-trees: unpack sparse directory entries During unpack_callback(), index entries are compared against tree entries. These are matched according to names and types. One goal is to decide if we should recurse into subtrees or simply operate on one index entry. In the case of a sparse-directory entry, we do not want to recurse into that subtree and instead simply compare the trees. In some cases, we might want to perform a merge operation on the entry, such as during 'git checkout <commit>' which wants to replace a sparse tree entry with the tree for that path at the target commit. We extend the logic within unpack_single_entry() to create a sparse-directory entry in this case, and then that is sent to call_unpack_fn(). There are some subtleties in this process. For instance, we need to update find_cache_entry() to allow finding a sparse-directory entry that exactly matches a given path. Use the new helper method sparse_dir_matches_path() for this. We also need to ignore conflict markers in the case that the entries correspond to directories and we already have a sparse directory entry.

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://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):
