From 4b33e60201c12f3a68441807444e3726853a3960 Mon Sep 17 00:00:00 2001 From: Patryk Obara Date: Sun, 28 Jan 2018 01:13:12 +0100 Subject: [PATCH] dir: convert struct sha1_stat to use object_id Convert the declaration of struct sha1_stat. Adjust all usages of this struct and replace hash{clr,cmp,cpy} with oid{clr,cmp,cpy} wherever possible. Rename it to struct oid_stat. Rename static function load_sha1_stat to load_oid_stat. Remove macro EMPTY_BLOB_SHA1_BIN, as it's no longer used.
