The --- Distributor requeues to the Credit task; the Credit task requeues to a --- secondary task which, in turn requeues to yet another task. This --- continues down the chain. At the furthest point of the chain the --- rendezvous is completed. To verify the action, the furthest task --- waits in the accept statement for a second message to arrive before --- completing. This second message can only arrive if none of the earlier --- tasks in the chain are blocked waiting for completion. Apart from --- the two Credit messages which are used to check the requeue chain one --- Debit message is sent to validate the mix. --- --- --- 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 --- ---! - - -with Report; -with ImpDef; - -procedure C954015 is - - -- Arbitrary test values - Credit_Return : constant := 1; - Debit_Return : constant := 2; - - -- Mechanism to count the number of Credit Message tasks completed - protected TC_Tasks_Completed is - procedure Increment; - function Count return integer; - private - Number_Complete : integer := 0; - end TC_Tasks_Completed; - - TC_Expected_To_Complete : constant integer := 3; - - - -- Values added to the Return_Value indicating passage through the - -- particular task - TC_Credit_Value : constant integer := 1; - TC_Sub_1_Value : constant integer := 2; - TC_Sub_2_Value : constant integer := 3; - TC_Sub_3_Value : constant integer := 4; - TC_Sub_4_Value : constant integer := 5; - -- - TC_Full_Value : integer := TC_Credit_Value + TC_Sub_1_Value + - TC_Sub_2_Value + TC_Sub_3_Value + - TC_Sub_4_Value; - - 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; - - - 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; - - -- The following are almost identical for the purpose of the test - task Credit_Sub_1 is - entry Input(Transaction : acc_Transaction_Record); - end Credit_Sub_1; - -- - task Credit_Sub_2 is - entry Input(Transaction : acc_Transaction_Record); - end Credit_Sub_2; - -- - task Credit_Sub_3 is - entry Input(Transaction : acc_Transaction_Record); - end Credit_Sub_3; - - -- This is the last in the chain - task Credit_Sub_4 is - entry Input(Transaction : acc_Transaction_Record); - end Credit_Sub_4; - - - -- Mechanism to count the number of Message tasks completed (Credit) - protected body TC_Tasks_Completed is - procedure Increment is - begin - Number_Complete := Number_Complete + 1; - end Increment; - - function Count return integer is - begin - return Number_Complete; - end Count; - end TC_Tasks_Completed; - - - - -- Assemble messages received from an external source - -- Creates a message task for each.
