clean: teach clean -d to preserve ignored paths There is an implicit assumption that a directory containing only untracked and ignored paths should itself be considered untracked. This makes sense in use cases where we're asking if a directory should be added to the git database, but not when we're asking if a directory can be safely removed from the working tree; as a result, clean -d would assume that an "untracked" directory containing ignored paths could be deleted, even though doing so would also remove the ignored paths. To get around this, we teach clean -d to collect ignored paths and skip an untracked directory if it contained an ignored path, instead just removing the untracked contents thereof. To achieve this, cmd_clean() has to collect all untracked contents of untracked directories, in addition to all ignored paths, to determine which untracked dirs must be skipped (because they contain ignored paths) and which ones should *not* be skipped. For this purpose, correct_untracked_entries() is introduced to prune a given dir_struct of untracked entries containing ignored paths and those untracked entries encompassed by the untracked entries which are not pruned away. A memory leak is also fixed in cmd_clean(). This also fixes the known breakage in t7300, since clean -d now skips untracked directories containing ignored paths.

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.
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):
