Check that execution continues +-- immediately following the asynchronous select. +-- +-- TEST DESCRIPTION: +-- Declare a main procedure containing an asynchronous select with a +-- protected entry call as triggering statement. Declare a protected +-- procedure which sets the protected entry's barrier true. Ensure +-- that the entry call is never accepted by not calling the protected +-- procedure; the barrier remains false, and the entry call from +-- asynchronous select is queued. Since the abortable part will complete +-- before the entry is accepted, the sequence of statements of the +-- triggering alternative is never executed. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + + +package C974007_0 is -- Automated teller machine abstraction. + + + -- Flags for testing purposes: + -- + Abortable_Part_Executed : Boolean := False; + Perform_Transaction_Executed : Boolean := False; + Triggering_Statement_Executed : Boolean := False; + + + 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; + + + protected type ATM_Keyboard_Protected is + entry Cancel_Pressed; + procedure Read_Key; + private + Last_Key_Pressed : Key_Enum := None; + end ATM_Keyboard_Protected; + + + 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 C974007_0; + + + --==================================================================-- + + +with Report; +package body C974007_0 is + + + protected body ATM_Keyboard_Protected is + + -- Barrier is false for the live of the test + entry Cancel_Pressed when (Last_Key_Pressed = Cancel) is + begin + Triggering_Statement_Executed := true; -- Test has failed + -- (Note: cannot call Report.Failed in the protected entry body] + end Cancel_Pressed; + + procedure Read_Key is -- Never + begin -- called. + -- Simulate a procedure which reads user keyboard input, and + -- which is called by some interrupt handler. + Last_Key_Pressed := Cancel; + end Read_Key; + + end ATM_Keyboard_Protected; + + + 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 + Abortable_Part_Executed := True; + end Validate_Card; + + + procedure Perform_Transaction (Card : in ATM_Card_Type) is + begin + Perform_Transaction_Executed := True; + end Perform_Transaction; + + +end C974007_0; + + + --==================================================================-- +with Report; + +with C974007_0; -- Automated teller machine abstraction. +use C974007_0; + +procedure C974007 is + + Card_Data : ATM_Card_Type; + +begin + + Report.Test ("C974007", "ATC: trigger is protected entry call" & + " and abortable part completes first"); + + Read_Card (Card_Data); + + declare + Keyboard : C974007_0.ATM_Keyboard_Protected; + begin + + -- -- + -- Asynchronous select is tested here -- + -- -- + + select + Keyboard.Cancel_Pressed; -- Barrier is never set true, so + -- entry call is queued and never + -- accepted. + + raise Transaction_Canceled; -- Should not be executed. + then abort + Validate_Card (Card_Data); -- This call completes before + -- Keyboard.Cancel_Pressed can be + -- accepted. + end select; + Perform_Transaction (Card_Data); -- Execution proceeds here after + -- Validate_Card completes. + exception + when Transaction_Canceled => + Report.Failed ("Triggering alternative sequence of statements " & + "executed"); + end; + + + if Triggering_Statement_Executed then + Report.Failed ("Triggering statement was executed"); + end if; + + if not Abortable_Part_Executed then + Report.Failed ("Abortable part not executed"); + end if; + + if not Perform_Transaction_Executed then + Report.Failed ("Statements following asynchronous select not " & + "executed"); + end if; + + Report.Result; + +end C974007; |
