From fa3a0c94dc88567b513e58835e5915f87da40af9 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Wed, 11 Feb 2009 10:15:30 -0800 Subject: [PATCH] Clear the delta base cache if a pack is rebuilt There is some risk that re-opening a regenerated pack file with different offsets could leave stale entries within the delta base cache that could be matched up against other objects using the same "struct packed_git*" and pack offset. Throwing away the entire delta base cache in this case is safer, as we don't have to worry about a recycled "struct packed_git*" matching to the wrong base object, resulting in delta apply errors while unpacking an object.
