Check that the corresponding entry body is executed +-- before the sequence of statements of the triggering alternative. +-- Check that the abortable part is not executed. +-- +-- 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. Force the +-- entry call to be accepted immediately by calling this protected +-- procedure prior to the asynchronous select. Since the entry call +-- is accepted immediately, the abortable part should never start. When +-- entry call completes, the sequence of statements of the triggering +-- alternative should execute. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + + +package C974006_0 is -- Automated teller machine abstraction. + + + -- Flag for testing purposes: + + Entry_Body_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 C974006_0; + + + --==================================================================-- + + +with Report; +package body C974006_0 is + + + protected body ATM_Keyboard_Protected is + + entry Cancel_Pressed when (Last_Key_Pressed = Cancel) is + begin + Entry_Body_Executed := True; + end Cancel_Pressed; + + procedure Read_Key is + begin + -- Simulate a procedure which processes 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 + Report.Failed ("Abortable part executed"); + end Validate_Card; + + + procedure Perform_Transaction (Card : in ATM_Card_Type) is + begin + Report.Failed ("Triggering alternative sequence of statements " & + "not fully executed"); + end Perform_Transaction; + + +end C974006_0; + + + --==================================================================-- + + +with Report; + +with C974006_0; -- Automated teller machine abstraction. +use C974006_0; + +procedure C974006 is + + Card_Data : ATM_Card_Type; + +begin + + Report.Test ("C974006", "ATC: trigger is protected entry call" & + " and completes first"); + + Read_Card (Card_Data); + + declare + Keyboard : C974006_0.ATM_Keyboard_Protected; + begin + + -- Simulate the situation where the user hits cancel before the + -- validation process can start: + Keyboard.Read_Key; -- Force Keyboard.Cancel_Pressed to + -- be accepted immediately. + + -- -- + -- Asynchronous select is tested here -- + -- -- + + select + Keyboard.Cancel_Pressed; -- Entry call is accepted immediately, + -- so abortable part does NOT start. + + if not Entry_Body_Executed then -- Executes after entry completes. + Report.Failed ("Triggering alternative sequence of statements " & + "executed before triggering statement complete"); + end if; + + raise Transaction_Canceled; -- Control passes to exception + -- handler. + then abort + Validate_Card (Card_Data); -- Should not be executed. + end select; + Perform_Transaction (Card_Data); -- Should not be reached. + exception + when Transaction_Canceled => + null; + end; + + Report.Result; + +end C974006; |
