We do this by sending two messages to the Distributor which --- requeues them to the Credit task. In the accept body of the Credit --- task we wait for the second message to arrive then check that an --- abort of the second message task does result in the requeue being --- removed. The Line Driver task which generates the messages and the --- Credit task communicate artificially in this test to arrange for the --- proper timing of the messages and the abort. One extra message is --- sent to the Debit task to ensure that the Distributor is still viable --- and has been unaffected by the abort. --- --- 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 problems for --- ACVC 2.0.1 --- ---! - -with Report; -with ImpDef; - -procedure C954013 is - - - -- Arbitrary test values - Credit_Return : constant := 1; - Debit_Return : constant := 2; - - - protected type Shared_Boolean (Initial_Value : Boolean := False) is - procedure Set_True; - procedure Set_False; - function Value return Boolean; - private - Current_Value : Boolean := Initial_Value; - end Shared_Boolean; - - protected body Shared_Boolean is - procedure Set_True is - begin - Current_Value := True; - end Set_True; - - procedure Set_False is - begin - Current_Value := False; - end Set_False; - - function Value return Boolean is - begin - return Current_Value; - end Value; - end Shared_Boolean; - - - TC_Debit_Message_Complete : Shared_Boolean (False); - TC_Credit_Message_Complete : Shared_Boolean (False); - - - type Transaction_Code is (Credit, Debit); - - type Transaction_Record; - type acc_Transaction_Record is access Transaction_Record; - type Transaction_Record is - record - ID : integer := 0; - Code : Transaction_Code := Debit; - Account_Number : integer := 0; - Stock_Number : integer := 0; - Quantity : integer := 0; - Return_Value : integer := 0; - TC_Message_Count : integer := 0; - TC_Thru_Dist : Boolean := false; - end record; - - - task type Message_Task is - entry Accept_Transaction (In_Transaction : acc_Transaction_Record); - end Message_Task; - type acc_Message_Task is access Message_Task; - - task Line_Driver is - entry Start; - end Line_Driver; - - task Distributor is - entry Input(Transaction : acc_Transaction_Record); - end Distributor; - - task Credit_Computation is - entry Input(Transaction : acc_Transaction_Record); - end Credit_Computation; - - task Debit_Computation is - entry Input(Transaction : acc_Transaction_Record); - end Debit_Computation; - - -- This protected object is here for Test Control purposes only - protected TC_Prt is - procedure Set_First_Has_Arrived; - procedure Set_Second_Has_Arrived; - procedure Set_Abort_Has_Completed; - function First_Has_Arrived return Boolean; - function Second_Has_Arrived return Boolean; - function Abort_Has_Completed return Boolean; - private - First_Flag, Second_Flag, Abort_Flag : Boolean := false; - end TC_Prt; - - protected body TC_Prt is - - Procedure Set_First_Has_Arrived is - begin - First_Flag := true; - end Set_First_Has_Arrived; - - Procedure Set_Second_Has_Arrived is - begin - Second_Flag := true; - end Set_Second_Has_Arrived; - - Procedure Set_Abort_Has_Completed is - begin - Abort_Flag := true; - end Set_Abort_Has_Completed; - - Function First_Has_Arrived return boolean is - begin - return First_Flag; - end First_Has_Arrived; - - Function Second_Has_Arrived return boolean is - begin - return Second_Flag; - end Second_has_Arrived; - - Function Abort_Has_Completed return boolean is - begin - return Abort_Flag; - end Abort_Has_Completed; - - end TC_PRT; - - -- Assemble messages received from an external source - -- Creates a message task for each.
