Nicolas Pitre	d60fc1c864	remove delta-against-self bit 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.

Sergey Vlasov	ce726ec8d8	[PATCH] NUL terminate the object data in patch_delta() At least pretty_print_commit() expects to get NUL-terminated commit data to work properly. unpack_sha1_rest(), which reads objects from separate files, and unpack_non_delta_entry(), which reads non-delta-compressed objects from pack files, already add the NUL byte after the object data, but patch_delta() did not do it, which caused problems with, e.g., git-rev-list --pretty when there are delta-compressed commit objects.

Nicolas Pitre	dcde55bc58	[PATCH] assorted delta code cleanup This is a wrap-up patch including all the cleanups I've done to the delta code and its usage. The most important change is the factorization of the delta header handling code. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Nicolas Pitre	69a2d426f0	[PATCH] denser delta header encoding Since the delta data format is not tied to any actual git object anymore, now is the time to add a small improvement to the delta data header as it is been done for packed object header. This patch allows for reducing the delta header of about 2 bytes and makes for simpler code. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Nicolas Pitre	a310d43494	[PATCH] Deltification library work by Nicolas Pitre. This patch adds the basic library functions to create and replay delta information. Also included is a test-delta utility to validate the code. diff-delta was based on LibXDiff written by Davide Libenzi Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Davide Libenzi <davidel@xmailserver.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
