After processing --- this, the Credit task sets the "overloaded" indicator. Once this --- indicator is set the Distributor (a protected object) queues lower --- priority transactions on a family of queues (Wait_for_Underload) in --- another protected object using a requeue. The Distributor still --- delivers high priority transactions. After two more high priority --- transactions have been processed by the Credit task the artificial --- test code clears the overload condition to the threshold level that --- allows only the items on the Medium priority queue of the family to be --- released. When these have been processed and checked the test code --- then lowers the priority threshold once again, allowing the Low --- priority items from the last queue in the family to be released, --- processed and checked. Note: the High priority queue in the family is --- not used. --- --- 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 C954023 is - - -- Artificial: number of messages required for this test - subtype TC_Trans_Range is integer range 1..8; - - TC_Credit_Messages_Expected : constant integer - := TC_Trans_Range'Last - 1; - - TC_Debit_Message_Complete : Boolean := false; - - - -- Mechanism for handshaking between tasks - protected TC_PO is - procedure Increment_Tasks_Completed_Count; - function Tasks_Completed_Count return integer; - function First_Message_Has_Arrived return Boolean; - procedure Set_First_Message_Has_Arrived; - private - Number_Complete : integer := 0; - Message_Arrived_Flag : Boolean := false; - end TC_PO; - -- - protected body TC_PO is - procedure Increment_Tasks_Completed_Count is - begin - Number_Complete := Number_Complete + 1; - end Increment_Tasks_Completed_Count; - - function Tasks_Completed_Count return integer is - begin - return Number_Complete; - end Tasks_Completed_Count; - - function First_Message_Has_Arrived return Boolean is - begin - return Message_Arrived_Flag; - end First_Message_Has_Arrived; - - procedure Set_First_Message_Has_Arrived is - begin - Message_Arrived_Flag := true; - end Set_First_Message_Has_Arrived; - - end TC_PO; - -begin - - Report.Test ("C954023", "Requeue from within a protected object" & - " to a family of entries in another protected object"); - - - declare -- encapsulate the test - - -- Arbitrary test values - Credit_Return : constant := 1; - Debit_Return : constant := 2; - - type Transaction_Code is (Credit, Debit); - type App_Priority is (Low, Medium, High); - type Priority_Block is array (App_Priority) of Boolean; - - type Transaction_Record; - type acc_Transaction_Record is access Transaction_Record; - type Transaction_Record is - record - ID : integer := 0; - Code : Transaction_Code := Debit; - Priority : App_Priority := High; - 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; - - protected Distributor is - procedure Set_Credit_Overloaded; - procedure Clear_Overload_to_Medium; - procedure Clear_Overload_to_Low; - entry Input (Transaction : acc_Transaction_Record); - private - Credit_Overloaded : Boolean := false; - end Distributor; - - protected Hold is - procedure Release_Medium; - procedure Release_Low; - -- Family of entry queues indexed by App_Priority - entry Wait_for_Underload (App_Priority) - (Transaction : acc_Transaction_Record); - private - Release : Priority_Block := (others => false); - end Hold; - - 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; - - -- - -- Dispose each input Transaction_Record to the appropriate - -- computation tasks - -- - protected body Distributor is - - procedure Set_Credit_Overloaded is - begin - Credit_Overloaded := true; - end Set_Credit_Overloaded; - - procedure Clear_Overload_to_Medium is - begin - Credit_Overloaded := false; - Hold.Release_Medium; -- Release all held messages on Medium - -- priority queue - end Clear_Overload_to_Medium; - - procedure Clear_Overload_to_Low is - begin - Credit_Overloaded := false; - Hold.Release_Low; -- Release all held messages on Low - -- priority queue - end Clear_Overload_to_Low; - - - - 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_Distrib := true; - - -- Pass this transaction on to the appropriate computation - -- task but temporarily hold low-priority transactions under - -- overload conditions - case Transaction.Code is - when Credit => - if Credit_Overloaded and Transaction.Priority /= High then - -- use the appropriate queue in the family - requeue Hold.Wait_for_Underload(Transaction.Priority) - with abort; - else - requeue Credit_Computation.Input with abort; - end if; - when Debit => - requeue Debit_Computation.Input with abort; - end case; - end Input; - end Distributor; - - - -- Low priority Message tasks are held on the Wait_for_Underload queue - -- while the Credit computation system is overloaded.
