* Unlocalized isspace and friendsLinus Torvalds2005-10-14
| | | | | | | | | 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>
* ignore new git-diff index header when computing patch idsKai Ruemmler2005-10-09
| | | | | | | | 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>
* Typofix: usage strings fix.Junio C Hamano2005-07-27
| | | | | | | The *_usage strings should not start with "usage: ", since the usage() function gives its own. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Add "git-patch-id" program to generate patch ID's.Linus Torvalds2005-06-23
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.
