From: Junio C Hamano Date: Fri, 4 Sep 2015 02:17:52 +0000 (-0700) Subject: Merge branch 'jk/fix-alias-pager-config-key-warnings' into maint X-Git-Tag: v2.5.2~15 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/fa6d3749edce0a5ba8c9150f984cc307e0092d0d?hp=-c Merge branch 'jk/fix-alias-pager-config-key-warnings' into maint Because the configuration system does not allow "alias.0foo" and "pager.0foo" as the configuration key, the user cannot use '0foo' as a custom command name anyway, but "git 0foo" tried to look these keys up and emitted useless warnings before saying '0foo is not a git command'. These warning messages have been squelched. * jk/fix-alias-pager-config-key-warnings: config: silence warnings for command names with invalid keys --- fa6d3749edce0a5ba8c9150f984cc307e0092d0d diff --combined cache.h index 4f554664c5,1121bbd230..c9e2f7487b --- a/cache.h +++ b/cache.h @@@ -43,14 -43,6 +43,14 @@@ int git_deflate_end_gently(git_zstream int git_deflate(git_zstream *, int flush); unsigned long git_deflate_bound(git_zstream *, unsigned long); +/* The length in bytes and in hex digits of an object name (SHA-1 value). */ +#define GIT_SHA1_RAWSZ 20 +#define GIT_SHA1_HEXSZ (2 * GIT_SHA1_RAWSZ) + +struct object_id { + unsigned char hash[GIT_SHA1_RAWSZ]; +}; + #if defined(DT_UNKNOWN) && !defined(NO_D_TYPE_IN_DIRENT) #define DTYPE(de) ((de)->d_type) #else @@@ -73,6 -65,13 +73,6 @@@ * * The value 0160000 is not normally a valid mode, and * also just happens to be S_IFDIR + S_IFLNK - * - * NOTE!
