Force the task to be waiting at +-- the accept statement so that the call is not queued and the rendezvous +-- is executed immediately. Simulate an unexpected exception in the +-- rendezvous. Use stripped down versions of called procedures to check +-- the correct path in the test. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + + +package C974009_0 is -- Automated teller machine abstraction. + + + Propagated_From_Task : exception; + Transaction_Canceled : exception; + + type Key_Enum is (None, Cancel, Deposit, Withdraw); + + type Card_Number_Type is private; + type Card_PIN_Type is private; + type ATM_Card_Type is private; + + task type ATM_Keyboard_Task is + entry Cancel_Pressed; + end ATM_Keyboard_Task; + + + procedure Validate_Card (Card : in ATM_Card_Type); + + procedure Perform_Transaction (Card : in ATM_Card_Type); + + +private + + type Card_Number_Type is range 1 .. 9999; + type Card_PIN_Type is range 100 .. 999; + + type ATM_Card_Type is record + Number : Card_Number_Type; + PIN : Card_PIN_Type; + end record; + +end C974009_0; + + + --==================================================================-- + + +with Report; +package body C974009_0 is + + + + -- One of these gets created as "Keyboard" for each transaction + -- + task body ATM_Keyboard_Task is + Key_Pressed : Key_Enum := None; + begin + accept Cancel_Pressed do -- queued entry call. + null; --:::: stub, user code for cancel + -- Now simulate an unexpected exception arising in the + -- user code + raise Propagated_From_Task; -- Propagate an exception. + + end Cancel_Pressed; + + Report.Failed ("Exception not propagated in ATM_Keyboard_Task"); + + exception + when Propagated_From_Task => + null; -- This is the expected test behavior + when others => + Report.Failed ("Unexpected Exception in ATM_Keyboard_Task"); + end ATM_Keyboard_Task; + + procedure Validate_Card (Card : in ATM_Card_Type) is + begin + Report.Failed ("Abortable part was executed"); + end Validate_Card; + + + procedure Perform_Transaction (Card : in ATM_Card_Type) is + begin + Report.Failed ("Exception not re-raised immediately following " & + "asynchronous select"); + end Perform_Transaction; + + +end C974009_0; + + + --==================================================================-- + + +with Report; +with ImpDef; + +with C974009_0; -- Automated teller machine abstraction. +use C974009_0; + +procedure C974009 is + + Card_Data : ATM_Card_Type; + +begin -- Main program. + + Report.Test ("C974009", "Asynchronous Select: Trigger is a call to a " & + "task entry, is not queued and is completed " & + "first by an exception"); + + + begin + + declare + -- Create the task for this transaction + Keyboard : C974009_0.ATM_Keyboard_Task; + begin + + -- Ensure task is waiting a the accept so the call is not queued + -- This is the time required to activate another task and allow it + -- to run to its first accept statement + -- + delay ImpDef.Switch_To_New_Task; + + -- -- + -- Asynchronous select is tested here -- + -- -- + + select + + Keyboard.Cancel_Pressed; + + raise Transaction_Canceled; -- Should not be executed. + then abort + Validate_Card (Card_Data); -- Keyboard.Cancel_Pressed is accepted + -- and propagates an exception before + -- this call is executed + end select; + + -- The propagated exception is re-raised here. + Perform_Transaction(Card_Data); -- Should not be reached. + + exception + when Transaction_Canceled => + Report.Failed ("Triggering alternative sequence of statements " & + "executed"); + when Propagated_From_Task => + null; -- This is the expected test path + when others => + Report.Failed ("Wrong exception raised"); + end; + + exception + when others => + Report.Failed ("Unexpected exception raised"); + end; + + Report.Result; + +end C974009; |
