Linus Torvalds	230f13225d	Create object subdirectories on demand This makes it possible to have a "sparse" git object subdirectory structure, something that has become much more attractive now that people use pack-files all the time. As a result of pack-files, a git object directory doesn't necessarily have any individual objects lying around, and in that case it's just wasting space to keep the empty first-level object directories around: on many filesystems the 256 empty directories will be aboue 1MB of diskspace. Even more importantly, after you re-pack a project that _used_ to be unpacked, you could be left with huge directories that no longer contain anything, but that waste space and take time to look through. With this change, "git prune-packed" can just do an rmdir() on the directories, and they'll get removed if empty, and re-created on demand. This patch also tries to fix up "write_sha1_from_fd()" to use the new common infrastructure for creating the object files, closing a hole where we might otherwise leave half-written objects in the object database. [jc: I unoptimized the part that really removes the fan-out directories to ease transition. init-db still wastes 1MB of diskspace to hold 256 empty fan-outs, and prune-packed rmdir()'s the grown but empty directories, but runs mkdir() immediately after that -- reducing the saving from 150KB to 146KB. These parts will be re-introduced when everybody has the on-demand capability.] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	215a7ad1ef	Big tool rename. As promised, this is the "big tool rename" patch. The primary differences since 0.99.6 are: (1) git-*-script are no more. The commands installed do not have any such suffix so users do not have to remember if something is implemented as a shell script or not. (2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean. There are backward compatibility symblic links so that you and Porcelains can keep using the old names, but the backward compatibility support is expected to be removed in the near future.

Ryan Anderson	d36ac03e45	[PATCH] Add support for directories to git-rename-script. Oh, and in the process, rewrite it in Perl. Signed-off-by: Ryan Anderson <ryan@michonline.com> Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Linus Torvalds	399144f21c	Add a "git rename" to help with - surprise surprise - renames It's stupid. We'd want to rename directories too, but this doesn't do that yet - easy enough to do per se, we just need to carefully list all the pathnames that got moved (and remember to ignore the files that weren't tracked but are in the subdirectory that got moved). Doing the directory case will require a bit more scripting.. Something like oldfiles=($(git-ls-files \| grep '^$src')) newfiles=($(git-ls-files \| sed ':^$src: s:^$src:$dst:')) mv $src $dst && git-update-cache --add --remove -- "${oldfiles[@]}" "${newfiles[@]}" might do it, except it needs to be done right, and carefully. Methinks perl is probably better at this. Hint hint..	20 years ago
