From 50546b15ed1df25837f8b291e6fa5bbcdb84635e Mon Sep 17 00:00:00 2001 From: Sun He Date: Mon, 3 Mar 2014 17:39:59 +0800 Subject: Use hashcpy() when copying object names We invented hashcpy() to keep the abstraction of "object name" behind it. Use it instead of calling memcpy() with hard-coded 20-byte length when moving object names between pieces of memory. Leave ppc/sha1.c as-is, because the function is about the SHA-1 hash algorithm whose output is and will always be 20 bytes.
