2006-05-08improve base85 generated assembly codeLibravatar Nicolas Pitre1-29/+35
This code is arguably pretty hot, if you use binary patches of course. This patch helps gcc generate both smaller and faster code especially in the error free path. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-05-05binary diff: further updates.Libravatar Junio C Hamano1-0/+134
This updates the user interface and generated diff data format. * "diff --binary" is used to signal that we want an e-mailable binary patch. It implies --full-index and -p. * "apply --allow-binary-replacement" acquired a short synonym "apply --binary". * After the "GIT binary patch\n" header line there is a token to record which binary patch mechanism was used, so that we can extend it later. Currently there are two mechanisms defined: "literal" and "delta". The former records the deflated postimage and the latter records the deflated delta from the preimage to postimage. For purely implementation convenience, I added the deflated length after these "literal/delta" tokens (otherwise the decoding side needs to guess and reallocate the buffer while inflating). Improvement patches are very welcomed. Signed-off-by: Junio C Hamano <junkio@cox.net>
