From e5f591720caea0c6645fa9852903a1c43d7c3672 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 4 Dec 2009 05:35:57 -0500 Subject: [PATCH] rerere: don't segfault on failure to open rr-cache The rr-cache directory should always exist if we are doing garbage collection (earlier code paths check this explicitly), but we may not necessarily succeed in opening it (for example, due to permissions problems). In that case, we should print an error message rather than simply segfaulting.
