> WKCFURLCacheCopyAllHostNamesInPersistentStoreForPartition This is a nightly or local build, isn't it supposed to use WebKit persistent cache, and not CFNetwork's? I don't know if this could happen when actually idling, something needed to send that clearCacheForOrigin message first.
Why is this cache clearing code running in a web process in the first place? For the legacy networking that doesn't use network process?
Probably, not sure. // FIXME (Multi-WebProcess): <rdar://problem/12239765> There is no need to relaunch all processes. One process to take care of persistent cache is enough. processPool()->sendToAllProcessesRelaunchingThemIfNecessary(Messages::WebResourceCacheManager::ClearCacheForOrigin(securityOrigin, cachesToClear));
Has not reproduced.
