Reviewed by Mitz Pettel RTL Preparation for upcoming work making LocalStorage persistent. StorageMaps normally have copy-on-write semantics to help support SessionStorage. For LocalStorage, we never want this behavior. When we forcefully import items into a StorageMap from the LocalStorage background thread, this new import method will be used. * storage/StorageMap.cpp: (WebCore::StorageMap::importItem): Add a deep-copy of the item to the map without worrying about copy-on-write. * storage/StorageMap.h: git-svn-id: http://svn.webkit.org/repository/webkit/trunk@32897 268f45cc-cd09-0410-ab3c-d52691b4dbfc
