Each task in each of the paths adds --- identifying information in the transaction being passed. This --- information is checked by the Message tasks on completion ensuring that --- the requeues have been placed on the correct queues. --- --- 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 --- 26 Nov 95 SAIC Fixed problems with shared global variables --- for ACVC 2.0.1 --- ---! - -with Report; -with ImpDef; - -procedure C954011 is - - - -- Arbitrary test values - Credit_Return : constant := 1; - Debit_Return : constant := 2; - - 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_Distrib : Boolean := false; - end record; - - protected type Message_Mgr is - procedure Mark_Complete; - function Is_Complete return Boolean; - private - Complete : Boolean := False; - end Message_Mgr; - - protected body Message_Mgr is - procedure Mark_Complete is - begin - Complete := True; - end Mark_Complete; - - Function Is_Complete return Boolean is - begin - return Complete; - end Is_Complete; - end Message_Mgr; - - TC_Debit_Message : Message_Mgr; - TC_Credit_Message : Message_Mgr; - - - 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; - - - - -- Assemble messages received from an external source - -- Creates a message task for each.
