* Do not use memcmp(sha1_1, sha1_2, 20) with hardcoded length.David Rientjes2006-08-17
| | | | | | | | | | | | | 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).

* Remove all void-pointer arithmetic.Florian Forster2006-06-20
| | | | | | | | 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>
* verify-pack: check integrity in a saner order.Junio C Hamano2006-04-27
| | | | | | | | Check internal integrity to report corrupt pack or idx, and then check cross-integrity between idx and pack. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

* remove delta-against-self bitNicolas Pitre2006-02-09
| | | | | | | | | | | | | | | | | | | | | After experimenting with code to add the ability to encode a delta against part of the deltified file, it turns out that resulting packs are _bigger_ than when this ability is not used. The raw delta output might be smaller, but it doesn't compress as well using gzip with a negative net saving on average. Said bit would in fact be more useful to allow for encoding the copying of chunks larger than 64KB providing more savings with large files. This will correspond to packs version 3. While the current code still produces packs version 2, it is made future proof so pack versions 2 and 3 are accepted. Any pack version 2 are compatible with version 3 since the redefined bit was never used before. When enough time has passed, code to use that bit to produce version 3 packs could be added.

* [PATCH] -Werror fixesTimo Sirainen2005-08-09
| | | | | | GCC's format __attribute__ is good for checking errors, especially with -Wformat=2 parameter. This fixes most of the reported problems against 2005-08-09 snapshot.

* [PATCH] Show more details of packfile with verify-pack -v.Junio C Hamano2005-06-30
| | | | | | | | | | | | | | | | | | | | | | | This implements show_pack_info() function used in verify-pack command when -v flag is used to obtain something like unpack-objects used to give when it was first written. It shows the following for each non-deltified object found in the pack: SHA1 type size offset For deltified objects, it shows this instead: SHA1 type size offset depth base_sha1 In order to get the output in the order that appear in the pack file for debugging purposes, you can do this: $ git-verify-pack -v packfile | sort -n -k 4,4 Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] verify-pack updates.Junio C Hamano2005-06-30
Nico pointed out that having verify_pack.c and verify-pack.c was confusing. Rename verify_pack.c to pack-check.c as suggested, and enhances the verification done quite a bit. - Built-in sha1_file unpacking knows that a base object of a deltified object _must_ be in the same pack, and takes advantage of that fact. - Earlier verify-pack command only checked the SHA1 sum for the entire pack file and did not look into its contents. It now checks everything idx file claims to have unpacks correctly. - It now has a hook to give more detailed information for objects contained in the pack under -v flag.
