From 3d20c636af05c44a6ff4df9309c2bca108ee149b Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Tue, 10 Feb 2009 13:36:12 -0800 Subject: Clear the delta base cache during fast-import checkpoint Otherwise we may reuse the same memory address for a totally different "struct packed_git", and a previously cached object from the prior occupant might be returned when trying to unpack an object from the new pack.
