Notes
Quote: Parnas and Wurges pioneered undesired events and exception handling of distributed applications
438 ;;Quote: lower levels can't use knowledge about higher levels; but undesired events need higher level information to determine the appropriate action
438 ;;Quote: the "abstract" machine detects attempts to violate its specifications; such undesired events invoke traps
439 ;;Quote: do not specify a module with properties that undesired events will frequently violate
439+;;Quote: a module's interface should include operations for communicating undesired events
439 ;;Quote: an undesired event may be propagating downward (i.e., violating virtual machine restrictions) or upward (i.e., reported by lower level)
439+;;Quote: an undesired event (UE) handler attempts recovery or adjusts its external state and reports the UE a level higher
439+;;Quote: a reported undesired event indicates a failure of the previous level's abstract machine
442 ;;Quote: determine cause of an undesired event by trying several recovery actions; starting with the least expensive one
