From e3343203aa2e322764ce68f04795137df6800f6f Mon Sep 17 00:00:00 2001 From: Edward Thomson Date: Wed, 26 Jan 2022 13:08:24 -0500 Subject: oid: provide an oid type to hash type map We intentionally separate oid types from hash types; a hash is a generic hunk of bytes, an object id has meaning and backs an object on disk. As a result of this separation, we need a 1:1 mapping. --- src/libgit2/oid.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/src/libgit2/oid.h b/src/libgit2/oid.h index 0503a18fb..5b467cb4e 100644 --- a/src/libgit2/oid.h +++ b/src/libgit2/oid.h @@ -10,6 +10,7 @@ #include "common.h" #include "git2/oid.h" +#include "hash.h" #define GIT_OID_NONE { 0, { 0 } } @@ -40,6 +41,18 @@ GIT_INLINE(size_t) git_oid_hexsize(git_oid_t type) return 0; } +GIT_INLINE(git_hash_algorithm_t) git_oid_algorithm(git_oid_t type) +{ + switch (type) { + case GIT_OID_SHA1: + return GIT_HASH_ALGORITHM_SHA1; + case GIT_OID_SHA256: + return GIT_HASH_ALGORITHM_SHA256; + } + + return 0; +} + /** * Format a git_oid into a newly allocated c-string. * -- cgit v1.2.1
