* Convert memcpy(a,b,20) to hashcpy(a,b).Shawn Pearce2006-08-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: Splitted the patch to "master" part, to be followed by a patch for merge-recursive.c which is not in "master" yet. Fixed the cast in the latter hunk to combine-diff.c which was wrong in the original. Also converted ones left-over in combine-diff.c, diff-lib.c and upload-pack.c ] Signed-off-by: Shawn O.

* patch-id: take "commit" prefix as well as "diff-tree" prefixJohannes Schindelin2006-06-231-0/+2
| | | | | | | | | | 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>
* Unlocalized isspace and friendsLinus Torvalds2005-10-141-1/+0
| | | | | | | | | 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 Ruemmler2005-10-091-0/+4
| | | | | | | | 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 Hamano2005-07-271-1/+1
| | | | | | | 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 Torvalds2005-06-231-0/+79
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.
