2008-10-02fix openssl headers conflicting with custom SHA1 implementationsLibravatar Nicolas Pitre1-2/+2
On ARM I have the following compilation errors: CC fast-import.o In file included from cache.h:8, from builtin.h:6, from fast-import.c:142: arm/sha1.h:14: error: conflicting types for 'SHA_CTX' /usr/include/openssl/sha.h:105: error: previous declaration of 'SHA_CTX' was here arm/sha1.h:16: error: conflicting types for 'SHA1_Init' /usr/include/openssl/sha.h:115: error: previous declaration of 'SHA1_Init' was here arm/sha1.h:17: error: conflicting types for 'SHA1_Update' /usr/include/openssl/sha.h:116: error: previous declaration of 'SHA1_Update' was here arm/sha1.h:18: error: conflicting types for 'SHA1_Final' /usr/include/openssl/sha.h:117: error: previous declaration of 'SHA1_Final' was here make: *** [fast-import.o] Error 1 This is because openssl header files are always included in git-compat-util.h since commit 684ec6c63c whenever NO_OPENSSL is not set, which somehow brings in <openssl/sha1.h> clashing with the custom ARM version. Compilation of git is probably broken on PPC too for the same reason. Turns out that the only file requiring openssl/ssl.h and openssl/err.h is imap-send.c. But only moving those problematic includes there doesn't solve the issue as it also includes cache.h which brings in the conflicting local SHA1 header file. As suggested by Jeff King, the best solution is to rename our references to SHA1 functions and structure to something git specific, and define those according to the implementation used.

2006-07-10Fix more typos, primarily in the codeLibravatar Pavel Roskin1-1/+1
The only visible change is that git-blame doesn't understand "--compability" anymore, but it does accept "--compatibility" instead, which is already documented. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-06-24A better-scheduled PPC SHA-1 implementation.Libravatar Unknown1-156/+195
This is about 15% faster that the current sha1ppc.S on a G4, and 5% faster on a G5 when hashing 10 million bytes, unaligned. (The G5 ratio seems to get better as the sizes fall.) It's also somewhat smaller, due to using load-multiple instructions. No copyright is claimed on the changes to Paul Mackerras' work below.
2005-04-22[PATCH] PPC assembly implementation of SHA1Libravatar Paul Mackerras1-0/+185
Here is a SHA1 implementation with the core written in PPC assembly. On my 2GHz G5, it does 218MB/s, compared to 135MB/s for the openssl version or 45MB/s for the mozilla version. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
