2006-06-23patch-id: take "commit" prefix as well as "diff-tree" prefixJohannes Schindelin
Some time ago we changed git-log in a massive way, and one consequence is that the keyword changed. Adjust patch-id for that. [jc: as Linus suggests, allowing both old and new prefix.] Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-15Unlocalized isspace and friendsLinus Torvalds
Do our own ctype.h, just to get the sane semantics: we want locale-independence, _and_ we want the right signed behaviour. Plus we only use a very small subset of ctype.h anyway (isspace, isalpha, isdigit and isalnum). Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-09ignore new git-diff index header when computing patch idsKai Ruemmler
Two else equal patches should not result in different checksums, only because they were applied to different versions of the file. Signed-off-by: Kai Ruemmler <kai.ruemmler@gmx.net> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-07-27Typofix: usage strings fix.Junio C Hamano
The *_usage strings should not start with "usage: ", since the usage() function gives its own. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-06-23Add "git-patch-id" program to generate patch ID's.Linus Torvalds
A "patch ID" is nothing but a SHA1 of the diff associated with a patch, with whitespace and line numbers ignored. As such, it's "reasonably stable", but at the same time also reasonably unique, ie two patches that have the same "patch ID" are almost guaranteed to be the same thing. IOW, you can use this thing to look for likely duplicate commits.
