I finally got around to looking at Alex' patch to teach update-index about gitlinks too, so that "git commit -a" along with any other explicit update-index scripts can work. I don't think there was anything wrong with Alex' patch, but the code he patched I felt was just so ugly that the added cases just pushed it over the edge. Especially as I don't think that patch necessarily did the right thing for a gitlink entry that already existed in the index, but that wasn't actually a real git repository in the working tree (just an empty subdirectory or a non-git snapshot because it hadn't wanted to track that particular subproject). So I ended up deciding to clean up the git-update-index handling the same way I tackled the directory traversal used by git-add earlier: by splitting the different cases up into multiple smaller functions, and just making the code easier to read (and adding more comments about the different cases). So this replaces the old "process_file()" with a new "process_path()" function that then just calls out to different helper functions depending on what kind of path it is. Processing a nondirectory ends up being just one of the simpler cases. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
//////////////////////////////////////////////////////////////// GIT - the stupid content tracker //////////////////////////////////////////////////////////////// "git" can mean anything, 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 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. It was originally written by Linus Torvalds with help of a group of hackers around the net. It is currently maintained by Junio C Hamano. Please read the file INSTALL for installation instructions. See Documentation/tutorial.txt to get started, then see Documentation/everyday.txt for a useful minimum set of commands, and "man git-commandname" for documentation of each command. CVS users may also want to read Documentation/cvs-migration.txt. Many Git online resources are accessible from http://git.or.cz/ including full documentation and Git related tools. 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. 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 http://marc.theaimsgroup.com/?l=git and other archival sites. The messages titled "A note from the maintainer", "What's in git.git (stable)" and "What's cooking in git.git (topics)" and the discussion following them on the mailing list give a good reference for project status, development direction and remaining tasks.
