Force the entry call to be --- queued by having the task call a procedure, prior to the corresponding --- accept statement, which simulates a routine waiting for user input --- (with a delay). --- --- Simulate a time-consuming routine in the abortable part by calling a --- procedure containing an infinite loop. Meanwhile, simulate input by --- the user (the delay expires), which causes the task to execute the --- accept statement corresponding to the triggering entry call. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- ---! - -package C974003_0 is -- Automated teller machine abstraction. - - - -- Flags for testing purposes: - -- - TC_Triggering_Statement_Completed : Boolean := False; - TC_Count : Integer := 1234; -- Global to defeat - -- optimization. - - 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; - - - Transaction_Canceled : exception; - - - task type ATM_Keyboard_Task is - entry Cancel_Pressed; - end ATM_Keyboard_Task; - - - procedure Read_Card (Card : in out ATM_Card_Type); - - 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 C974003_0; - - - --==================================================================-- - - -with Report; -with ImpDef; - -package body C974003_0 is - - - procedure Listen_For_Input (Key : out Key_Enum) is - begin - -- Model the situation where the user waits a bit for the card to - -- be validated, then presses cancel before it completes. - - -- Delay long enough to force queuing of Keyboard.Cancel_Pressed. - delay ImpDef.Minimum_Task_Switch; - - if Report.Equal (3, 3) then -- Always true. - Key := Cancel; - end if; - end Listen_For_Input; - - - - -- One of these gets created as "Keyboard" for each transaction - -- - task body ATM_Keyboard_Task is - Key_Pressed : Key_Enum := None; - begin - loop - -- Force entry calls - Listen_For_Input (Key_Pressed); -- to be queued, - -- then set guard to - -- true. - select - when (Key_Pressed = Cancel) => -- Guard is now - accept Cancel_Pressed do -- true, so accept - TC_Triggering_Statement_Completed := True; -- queued entry - end Cancel_Pressed; -- call. - - -- User has cancelled the transaction so we exit the - -- loop and allow the task to terminate - exit; - else - Key_Pressed := None; - end select; - - end loop; - exception - when others => - Report.Failed ("Unexpected Exception in ATM_Keyboard_Task"); - end ATM_Keyboard_Task; - - - - procedure Read_Card (Card : in out ATM_Card_Type) is - begin - Card.Number := 9999; - Card.PIN := 111; - end Read_Card; - - - procedure Validate_Card (Card : in ATM_Card_Type) is - begin - -- Simulate an exceedingly long validation activity. - loop -- Infinite loop. - TC_Count := (TC_Count + 1) mod Integer (Card.PIN); - -- Synch. point to allow transfer of control to Keyboard - -- task during this simulation - delay ImpDef.Minimum_Task_Switch; - exit when not Report.Equal (TC_Count, TC_Count); -- Always false. - end loop; - end Validate_Card; - - - procedure Perform_Transaction (Card : in ATM_Card_Type) is - begin - Report.Failed ("Triggering alternative sequence of statements " & - "not executed"); - if not TC_Triggering_Statement_Completed then - Report.Failed ("Triggering statement did not complete"); - end if; - if TC_Count = 1234 then - -- Initial value is unchanged - Report.Failed ("Abortable part did not execute"); - end if; - end Perform_Transaction; - - -end C974003_0; - - - --==================================================================-- - - -with Report; - -with C974003_0; -- Automated teller machine abstraction. -use C974003_0; - -procedure C974003 is - - Card_Data : ATM_Card_Type; - -begin -- Main program. - - Report.Test ("C974003", "Asynchronous Select: Trigger is queued on a " & - "task entry and completes first"); - - Read_Card (Card_Data); - - declare - -- Create the task for this transaction - Keyboard : C974003_0.ATM_Keyboard_Task; - begin - - -- -- - -- Asynchronous select is tested here -- - -- -- - - select - Keyboard.Cancel_Pressed; -- Entry call is initially queued, so - -- abortable part starts. - - raise Transaction_Canceled; -- This is executed after Validate_Card - -- is aborted. - then abort - Validate_Card (Card_Data); -- Keyboard.Cancel_Pressed is accepted - -- and completes before this call - -- finishes; it is then aborted. - - -- Check that the whole of the abortable part is aborted, not - -- just the statement in the abortable part that was executing - -- at the time - Report.Failed ("Abortable part not aborted"); - - end select; - - Perform_Transaction (Card_Data); -- Should not be reached. - exception - when Transaction_Canceled => - if not TC_Triggering_Statement_Completed then - Report.Failed ("Triggering alternative sequence of statements " & - "executed but triggering statement not complete"); - end if; - if TC_Count = 1234 then - -- Initial value is unchanged - Report.Failed ("Abortable part did not execute"); - end if; - end; - - Report.Result; - -end C974003; |
