Alan Gates updated HIVE-10010:
------------------------------
Attachment: HIVE-10010.patch
This patch completely reworks SharedStorageDescriptor. It is now much simpler.
Rather than having a pointer to an actual shared object, it does a shallow
copy of the StorageDescriptor it is handed. Then if a user does a get on a
nested structure or list, that structure or list is deep copied. That way if
the user modified the structure or list the modifications apply only to current
StorageDescriptor, not to all of the SharedStorageDescriptors that are sharing
the nested structures and lists.
