Derrick Stolee 71f82d032f sparse-index: expand_to_path() Some users of the index API have a specific path they are looking for, but choose to use index_file_exists() to rely on the name-hash hashtable instead of doing binary search with index_name_pos(). These users only need to know a yes/no answer, not a position within the cache array. When the index is sparse, the name-hash hash table does not contain the full list of paths within sparse directories. It _does_ contain the directory names for the sparse-directory entries. Create a helper function, expand_to_path(), for intended use with the name-hash hashtable functions. The integration with name-hash.c will follow in a later change. The solution here is to use ensure_full_index() when we determine that the requested path is within a sparse directory entry. This will populate the name-hash hashtable as the index is recomputed from scratch. There may be cases where the caller is trying to find an untracked path that is not in the index but also is not within a sparse directory entry. We want to minimize the overhead for these requests. If we used index_name_pos() to find the insertion order of the path, then we could determine from that position if a sparse-directory exists. (In fact, just calling index_name_pos() in that case would lead to expanding the index to a full index.) However, this takes O(log N) time where N is the number of cache entries. To keep the performance of this call based mostly on the input string, use index_file_exists() to look for the ancestors of the path. Using the heuristic that a sparse directory is likely to have a small number of parent directories, we start from the bottom and build up. Use a string buffer to allow mutating the path name to terminate after each slash for each hashset test.

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.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):

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
