           Summary: IPC in WebKit2 is not type-safe
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: NeedsRadar
          Severity: Normal
          Priority: P2
         Component: WebKit2
        AssignedTo: webkit-unassigned at lists.webkit.org

Consider this code from WebPageProxy::mouseEvent:

    process()->send(WebPageMessage::MouseEvent, m_pageID, CoreIPC::In(event));

The compiler does not enforce that a WebMouseEvent is passed to CoreIPC::In when the message ID is WebPageMessage::MouseEvent. It's easy to make mistakes which will result in crashes on the other end of the connection.

We should make our IPC type-safe.
