Update CachedObjectDirectory when inserting objects
If an ObjectInserter is created from a CachedObjectDirectory, we need to ensure the cache is updated whenever a new loose object is actually added to the loose objects directory, otherwise a future read from an ObjectReader on the CachedObjectDirectory might not be able to open the newly created object. We mostly had the infrastructure in place to implement this due to the injection of unpacked large deltas, but we didn't have a way to pass the ObjectId from ObjectDirectoryInserter to CachedObjectDirectory, because the inserter was using the underlying ObjectDirectory and not the CachedObjectDirectory. Redirecting to CachedObjectDirectory ensures the cache is updated. Change-Id: I1f7bdfacc7ad77ebdb885f655e549cc570652225 Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
