2007-04-10pack-redundant.c: learn about index v2Libravatar Nicolas Pitre1-20/+27
Initially the conversion was made using nth_packed_object_sha1() which made this file completely index version agnostic. Unfortunately the overhead was quite significant so I went back to raw index walking but with selectable base and step values which brought back similar performances as the original.

2007-03-16[PATCH] clean up pack index handling a bitLibravatar Nicolas Pitre1-14/+16
Especially with the new index format to come, it is more appropriate to encapsulate more into check_packed_git_idx() and assume less of the index format in struct packed_git. To that effect, the index_base is renamed to index_data with void * type so it is not used directly but other pointers initialized with it. This allows for a couple pointer cast removal, as well as providing a better generic name to grep for when adding support for new index versions or formats. And index_data is declared const too while at it. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-03-07Use off_t when we really mean a file offset.Libravatar Shawn O. Pearce1-4/+4
Not all platforms have declared 'unsigned long' to be a 64 bit value, but we want to support a 64 bit packfile (or close enough anyway) in the near future as some projects are getting large enough that their packed size exceeds 4 GiB. By using off_t, the POSIX type that is declared to mean an offset within a file, we support whatever maximum file size the underlying operating system will handle. For most modern systems this is up around 2^60 or higher. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-17Do not use memcmp(sha1_1, sha1_2, 20) with hardcoded length.Libravatar David Rientjes1-7/+7
Introduces global inline: hashcmp(const unsigned char *sha1, const unsigned char *sha2) Uses memcmp for comparison and returns the result based on the length of the hash name (a future runtime decision).

2006-06-20Remove all void-pointer arithmetic.Libravatar Florian Forster1-9/+9
ANSI C99 doesn't allow void-pointer arithmetic. This patch fixes this in various ways. Usually the strategy that required the least changes was used. Signed-off-by: Florian Forster <octo@verplant.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-12-21git-pack-redundant: speed and memory usage improvementsLibravatar Lukas Sandström1-80/+69
Slab allocation of llist entries gives some speed improvements. Not computing the pack_list permutaions all at once reduces memory usage greatly on repositories with many packs. Signed-off-by: Lukas Sandström <lukass@etek.chalmers.se> Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-11-23pack-redundant: type cleanups.Libravatar Junio C Hamano1-10/+10
Binary representation of object names are unsigned char[20], not signed. Also verbose output had %lu format printing size_t without (unsigned long) cast other places already had, so match that. Using format %zu was suggested but might not be supported as widely. Noted by Morten Welinder, fixed with input from H. Peter Anvin and Hideaki Yoshifuji.

2005-11-22Make git-pack-redundant take a list of unimportant objs on stdinLibravatar Lukas Sandström1-0/+21
This lets us do "git-fsck-objects --full --unreachable | cut -d ' ' -f3 | git-pack-redundant --all", which will keep git-pack-redundant from keeping packs just because they contain unreachable objects. Also add some more --verbose output. Signed-off-by: Lukas Sandström <lukass@etek.chalmers.se> Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-11-11Make git-pack-redundant consider alt-odbsLibravatar Lukas_Sandström1-53/+94
This patch changes git-pack-redundant so that packfiles in alternate object directories also are considered when deciding which objects are redundant. This functionality is controlled by the flag '--alt-odb'. Also convert the other flags to the long form, and update docs and git-repack accordingly.
