2005-12-12diff-delta.c: allow delta with empty blob.Libravatar Junio C Hamano1-1/+1
Delta computation with an empty blob used to punt and returned NULL. This commit allows creation with empty blob; all combination of empty->empty, empty->something, and something->empty are allowed. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-06-29[PATCH] assorted delta code cleanupLibravatar Nicolas Pitre1-1/+2
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>
2005-06-28[PATCH] denser delta header encodingLibravatar Nicolas Pitre1-20/+14
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>
2005-06-25Add a "max_size" parameter to diff_delta()Libravatar Linus Torvalds1-1/+7
Anything that generates a delta to see if two objects are close usually isn't interested in the delta ends up being bigger than some specified size, and this allows us to stop delta generation early when that happens.
2005-05-19[PATCH] Deltification library work by Nicolas Pitre.Libravatar Nicolas Pitre1-0/+333
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>
