The path-walk API prunes trees and blobs when a sparse-checkout pattern list is provided, which is the correct behavior for 'git backfill --sparse' since it only needs to fill in objects at paths within the sparse cone. However, a future change will use the path-walk API with a sparse:<oid> filter that restricts only blobs while retaining all reachable trees. To support both behaviors, add a 'pl_sparse_trees' flag to path_walk_info. When set (as in 'git backfill --sparse' and the --stdin-pl test helper mode), the sparse patterns prune both trees and blobs. When unset, only blobs are filtered and all trees are walked and reported. Additionally, move the SEEN flag assignment in add_tree_entries() to after the sparse pattern and pathspec checks. Previously, SEEN was set immediately upon discovering an object, before checking whether its path matched the sparse patterns. When the same object ID appeared at multiple paths (e.g. sibling directories with identical contents), the first path to be visited would mark the object as SEEN. If that path was outside the sparse cone, the object would be skipped there but also never discovered at its in-cone path. By deferring the SEEN flag until after the checks pass, objects that are skipped due to sparse filtering remain discoverable at other paths where they may be in scope.

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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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
