After --- processing this the Credit task sets the "overloaded" indicator. Once --- this indicator is set the Distributor queues low priority transactions --- on a Wait_for_Underload queue in the same task using a requeue. The --- Distributor still delivers high priority transactions. After two high --- priority transactions have been processed by the Credit task it clears --- the overload condition. The low priority transactions should now be --- delivered. --- --- This series of tests uses a simulation of a transaction driven --- processing system. Line Drivers accept input from an external source --- and build them into transaction records. These records are then --- encapsulated in message tasks which remain extant for the life of the --- transaction in the system. The message tasks put themselves on the --- input queue of a Distributor which, from information in the --- transaction and/or system load conditions forwards them to other --- operating tasks. These in turn might forward the transactions to yet --- other tasks for further action. The routing is, in real life, dynamic --- and unpredictable at the time of message generation. All rerouting in --- this model is done by means of requeues. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- 25 Nov 95 SAIC Fixed shared global variable problem for --- ACVC 2.0.1 --- 14 Mar 03 RLB Fixed a race condition and an incorrect termination --- condition in the test. ---! - -with Report; -with ImpDef; -with Ada.Calendar; - -procedure C954012 is - - function "=" (X,Y: Ada.Calendar.Time) return Boolean - renames Ada.Calendar."="; - - -- Arbitrary test values - Credit_Return : constant := 1; - Debit_Return : constant := 2; - - - -- This is used as an "initializing" time for the messages as they are - -- created.
