From f5552aee39d664bb8774c205341abd6db74b38d3 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Fri, 23 Jan 2009 10:07:01 +0100 Subject: [PATCH] sha1_file: add a "read_sha1_file_repl" function This new function will replace "read_sha1_file". This latter function becoming just a stub to call the former will a NULL "replacement" argument. This new function is needed because sometimes we need to use the replacement sha1.
