Failure handling and debugging with causalities

摘要: Various technologies and techniques are disclosed that improve failure handling debugging in message driven environments. A diagramming tool allows a user to graphically nest one or more functional components of the data flow diagram create fault handler. The handler is associated with component be called when occurs within any nested components. One application executables synthesized from diagram. When created at runtime, causality for component. has an exception port receiving messages unhandled also coordination allow context and/or other applications access error history history.
