            Bug ID: 185715
           Summary: Conversion between SecurityOriginData and
                    DatabaseIdentifier is asymmetric when port is null
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: sihui_liu at apple.com

Here is current case:
SecurityOriginData(port = null) -> DatabaseIdentifier(port = 0) -> SecurityOriginData(port = 0)
which should be:
SecurityOriginData(port = null) -> DatabaseIdentifier -> SecurityOriginData(port = null)

Currently LocalStorageDatabase sometimes unlinks database files when they are still in use. We have code to close the database before deletion, but due to the conversion issue about identifier, we failed to delete the correct database.
