I've amended this one and the range diff since the pushout yesterday looks like this. 1: 8a030f1796 ! 1: 02d21d4117 hex: drop sha1_to_hex() @@ Commit message hex: drop sha1_to_hex() There's only a single caller left of sha1_to_hex(), since everybody now - uses oid_to_hex() instead. This case is in the sha1dc wrapper, where we + uses hash_to_hex() instead. This case is in the sha1dc wrapper, where we print a hex sha1 when we find a collision. This one will always be sha1, - regardless of the current hash algorithm, so we can't use oid_to_hex() + regardless of the current hash algorithm, so we can't use hash_to_hex() here. In practice we'd probably not be running sha1 at all if it isn't the current algorithm, but it's possible we might still occasionally need to compute a sha1 in a post-sha256 world. @@ cache.h: int hex_to_bytes(unsigned char *binary, const char *hex, size_t len); * buffers, making it safe to make multiple calls for a single statement, like: * - * printf("%s -> %s", sha1_to_hex(one), sha1_to_hex(two)); -+ * printf("%s -> %s", oid_to_hex(one), oid_to_hex(two)); ++ * printf("%s -> %s", hash_to_hex(one), hash_to_hex(two)); */ char *hash_to_hex_algop_r(char *buffer, const unsigned char *hash, const struct git_hash_algo *); char *oid_to_hex_r(char *out, const struct object_id *oid);
