Check that the requeue is placed on the correct entry; that the --- original caller waits for the completion of the requeue and continues --- after the requeued rendezvous. Check that the requeue does not block. --- Specifically, check a requeue with abort from a protected entry to --- an entry in a task. --- --- TEST DESCRIPTION: --- --- In the Distributor protected object, requeue two successive calls on --- the entries of two separate target tasks. 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. --- There is an artificial guard on the Credit Task to ensure that the --- input is queued; this guard is released by the Debit task which --- handles its input immediately. This ensures that we have one of the --- requeued items actually queued for later handling and also verifies --- that the requeuing process (in the protected object) is not blocked. --- --- 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 object 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 --- 06 Nov 95 SAIC Fixed problems for ACVC 2.0.1 --- ---! - -with Report; -with ImpDef; - -procedure C954020 is - Verbose : constant Boolean := False; - - -- Arbitrary test values - Credit_Return : constant := 1; - Debit_Return : constant := 2; - - protected type Message_Status is - procedure Set_Complete; - function Complete return Boolean; - private - Is_Complete : Boolean := False; - end Message_Status; - - protected body Message_Status is - procedure Set_Complete is - begin - Is_Complete := True; - end Set_Complete; - - function Complete return Boolean is - begin - return Is_Complete; - end Complete; - end Message_Status; - - TC_Debit_Message : Message_Status; - TC_Credit_Message : Message_Status; - - 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 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; - - protected Time_Lock is - procedure Credit_Start; - function Credit_Enabled return Boolean; - private - Credit_OK : Boolean := false; - end Time_Lock; - - protected body Time_Lock is - procedure Credit_Start is - begin - Credit_OK := true; - end Credit_Start; - - function Credit_Enabled return Boolean is - begin - return Credit_OK; - end Credit_Enabled; - end Time_Lock; - - - - protected Distributor is - entry Input (Transaction : acc_Transaction_Record); - end Distributor; - -- - -- - -- Dispose each input Transaction_Record to the appropriate - -- computation tasks - -- - protected body Distributor is - entry Input (Transaction : acc_Transaction_Record) when true is - -- barrier is always open - begin - -- Test Control: Set the indicator in the message to show it has - -- passed through the Distributor object - Transaction.TC_thru_Dist := true; - - -- Pass this transaction on to the appropriate computation - -- task - case Transaction.Code is - when Credit => - requeue Credit_Computation.Input with abort; - when Debit => - requeue Debit_Computation.Input with abort; - end case; - end Input; - end Distributor; - - - - - -- Assemble messages received from an external source - -- Creates a message task for each.
