2006-03-09fsck-objects: Remove --standaloneLibravatar Junio C Hamano1-15/+5
The fsck-objects command (back then it was called fsck-cache) used to complain if objects referred to by files in .git/refs/ or objects stored in files under .git/objects/??/ were not found as stand-alone SHA1 files (i.e. found in alternate object pools or packed archives stored under .git/objects/pack). Back then, packs and alternates were new curiosity and having everything as loose objects were the norm. When we adjusted the behaviour of fsck-cache to consider objects found in packs are OK, we introduced the --standalone flag as a backward compatibility measure. It still correctly checks if your repository is complete and consists only of loose objects, so in that sense it is doing the "right" thing, but checking that is pointless these days. This commit removes --standalone flag. See also: 23676d407c63a6f67f8ce3ff192199bda03e6a03 8a498a05c3c6b2f53db669b24f36257ab213eb4c Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-26Use setenv(), fix warningsLibravatar Timo Hirvonen1-1/+1
- Fix -Wundef -Wold-style-definition warnings - Make pll_free() static [jc: original patch by Timo had another unrelated bits: - Use setenv() instead of putenv() I'm postponing that part for now.] Signed-off-by: Timo Hirvonen <tihirvon@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-12Use a hashtable for objects instead of a sorted listLibravatar Johannes Schindelin1-1/+4
In a simple test, this brings down the CPU time from 47 sec to 22 sec. Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-01-21fsck-objects: support platforms without d_ino in struct dirent.Libravatar Junio C Hamano1-2/+11
The d_ino field is only used for performance reasons in fsck-objects. On a typical filesystem, i-number tends to have a strong correlation with where the actual bits sit on the disk platter, and we sort the entries to allow us scan things that ought to be close together together. If the platform lacks support for it, it is not a big deal. Just do not use d_ino for sorting, and scan them unsorted. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-11-28fsck-objects: work from subdirectory.Libravatar Junio C Hamano1-0/+2
Not much point making it work from subdirectory, but for a consistency make it so. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-11-15Rework object refs tracking to reduce memory usageLibravatar Sergey Vlasov1-9/+13
Store pointers to referenced objects in a variable sized array instead of linked list. This cuts down memory usage of utilities which use object references; e.g., git-fsck-objects --full on the git.git repository consumes about 2 MB of memory tracked by Massif instead of 7 MB before the change. Object refs are still the biggest consumer of memory (57%), but the malloc overhead for a single block instead of a linked list is substantially smaller.

2005-11-15git-fsck-objects: Free tree entries after useLibravatar Sergey Vlasov1-0/+7
The Massif tool of Valgrind revealed that parsed tree entries occupy more than 60% of memory allocated by git-fsck-objects. These entries can be freed immediately after use, which significantly decreases memory consumption. Signed-off-by: Sergey Vlasov <vsu@altlinux.ru> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-08Create object subdirectories on demandLibravatar Linus Torvalds1-3/+2
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>
2005-10-01Add git-symbolic-refLibravatar Junio C Hamano1-18/+10
This adds the counterpart of git-update-ref that lets you read and create "symbolic refs". By default it uses a symbolic link to represent ".git/HEAD -> refs/heads/master", but it can be compiled to use the textfile symbolic ref. The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah .git/HEAD' have been converted to use new git-symbolic-ref command, so that they can deal with either implementation.

2005-09-20[PATCH] Make the git-fsck-objects diagnostics more usefulLibravatar Petr Baudis1-34/+48
Actually report what exactly is wrong with the object, instead of an ambiguous 'bad sha1 file' or such. In places where we already do, unify the format and clean the messages up. Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-09Retire support for old environment variables.Libravatar Junio C Hamano1-1/+1
We have deprecated the old environment variable names for quite a while and now it's time to remove them. Gone are: SHA1_FILE_DIRECTORIES AUTHOR_DATE AUTHOR_EMAIL AUTHOR_NAME COMMIT_AUTHOR_EMAIL COMMIT_AUTHOR_NAME SHA1_FILE_DIRECTORY Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-07Big tool rename.Libravatar Junio C Hamano1-0/+537
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.
