2006-04-04Use blob_, commit_, tag_, and tree_type throughout.Libravatar Peter Eriksen1-4/+8
This replaces occurences of "blob", "commit", "tag", and "tree", where they're really used as type specifiers, which we already have defined global constants for. Signed-off-by: Peter Eriksen <s022018@student.dtu.dk> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-09remove delta-against-self bitLibravatar Nicolas Pitre1-3/+3
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.

2005-12-26avoid asking ?alloc() for zero bytes.Libravatar Junio C Hamano1-8/+14
Avoid asking for zero bytes when that change simplifies overall logic. Later we would change the wrapper to ask for 1 byte on platforms that return NULL for zero byte request. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-12-21An off-by-one bug found by valgrindLibravatar Pavel Roskin1-1/+1
Insufficient memory is allocated in index-pack.c to hold the *.idx name. One more byte should be allocated to hold the terminating 0. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-12Fix packname hash generation.Libravatar Junio C Hamano1-2/+13
This changes the generation of hash packfiles have in their names, from "hash of object names as fed to us" to "hash of object names in the resulting pack, in the order they appear in the index file". The new "git-index-pack" command is taught to output the computed hash value to its standard output. With this, we can store downloaded pack in a temporary file without knowing its final name, run git-index-pack to generate idx for it while finding out its final name, and then rename the pack and idx to their final names.

2005-10-12Add git-index-pack utilityLibravatar Sergey Vlasov1-0/+451
git-index-pack builds a pack index file for an existing packed archive. With this utility a packed archive which was transferred without the corresponding pack index can be added to objects/pack/ without repacking.
