2006-03-04count-delta: no need for this anymore.Junio C Hamano
This is a companion patch to e29e1147e485654d90a0ea0fd5fb7151bb194265 which made diffcore similarity estimator independent from the packfile deltifier. There is no reason for us to be counting the xdelta anymore. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-06-03[PATCH] Tweak count-delta interfaceJunio C Hamano
Make it return copied source and insertion separately, so that later implementation of heuristics can use them more flexibly. This does not change the heuristics implemented in diffcore-rename nor diffcore-break in any way. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-25[PATCH] Update rename/copy similarity estimator.Junio C Hamano
The second round similarity estimator simply used the size of the xdelta itself to estimate the extent of damage. This patch keeps that logic to detect big insertions to terminate the check early, but otherwise looks at the generated delta in order to estimate the extent of edit more accurately.
