* test-sha1: add a binary output modeJeff King2013-08-221-3/+12
| | | | | | | | | | | | The test-sha1 helper program will run our internal sha1 routines over its input and output the 40-byte hex sha1. Sometimes, however, it is useful to have the binary 20-byte sha1 (and it's a pain to convert back in the shell). Let's add a "-b" option to output the binary version.

* Convert existing die(..., strerror(errno)) to die_errno()Thomas Rast2009-06-271-1/+1
| | | | | | | | | | | Change calls to die(..., strerror(errno)) to use the new die_errno(). In the process, also make slight style adjustments: at least state _something_ about the function that failed (instead of just printing the pathname), and put paths in single quotes.

* fix openssl headers conflicting with custom SHA1 implementationsNicolas Pitre2008-10-021-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
