From 12fe0f2d1eb18aab2964532e99d11d4311d558eb Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Fri, 16 Jul 2010 10:41:09 -0700 Subject: [PATCH] Discard the uncompressed delta as soon as its compressed The DeltaCache will most likely need to copy the compressed delta into a new buffer in order to compact away the wasted space at the end caused by over allocation. Since we don't need the uncompressed format anymore, null out our only reference to it so the GC can reclaim this memory if it needs to perform a collection in order to satisfy the cache's allocation attempt.
