Nicolas Pitre	8e1454b5ad	diff-delta: big code simplification This is much smaller and hopefully clearer code now. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Nicolas Pitre	fe474b588b	diff-delta: fold two special tests into one plus cleanups Testing for realloc and size limit can be done with only one test per loop. Make it so and fix a theoretical off-by-one comparison error in the process. The output buffer memory allocation is also bounded by max_size when specified. Finally make some variable unsigned to allow the handling of files up to 4GB in size instead of 2GB.

Peter Eriksen	04fe2a1706	Use adler32() from zlib instead of defining our own. Since we already depend on zlib, we don't need to define our own adler32(). Spotted by oprofile. Signed-off-by: Peter Eriksen <s022018@student.dtu.dk> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Nicolas Pitre	e5e3a9d8f9	small cleanup for diff-delta.c This patch removes unused remnants of the original xdiff source. No functional change. Possible tiny speed improvement. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	c7a45bd20e	Revert "diff-delta.c: allow delta with empty blob." This reverts `962537a3eb` commit to play safe.	19 years ago
Junio C Hamano	962537a3eb	diff-delta.c: allow delta with empty blob. 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>	19 years ago
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
Linus Torvalds	75c42d8cc3	Add a "max_size" parameter to diff_delta() 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.	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
