Use "others" handlers in the --- protected operations. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- ---! - -package CB20006_0 is -- Package Semaphore. - - Reraised_In_Function, - Reraised_In_Procedure, - Handled_In_Function_Caller, - Handled_In_Procedure_Caller : Boolean := False; - - Resource_Overflow, - Resource_Underflow : exception; - - protected type Counting_Semaphore (Max_Resources : Integer) is - procedure Secure; - function Resource_Limit_Exceeded return Boolean; - procedure Release; - private - Count : Integer := Max_Resources; - end Counting_Semaphore; - -end CB20006_0; - - --=================================================================-- - -with Report; - -package body CB20006_0 is -- Package Semaphore. - - protected body Counting_Semaphore is - - procedure Secure is - begin - if (Count = 0) then -- No resources left to secure. - raise Resource_Underflow; - Report.Failed - ("Program control not transferred by raise in Procedure Secure"); - else - Count := Count - 1; -- Available resources decremented. - end if; - exception - when Resource_Underflow => - Reraised_In_Procedure := True; - raise; -- Exception propagated to caller. - Report.Failed ("Exception not propagated to caller from Secure"); - when others => - Report.Failed ("Unexpected exception raised in Secure"); - end Secure; - - - function Resource_Limit_Exceeded return Boolean is - begin - if (Count > Max_Resources) then - raise Resource_Overflow; -- Exception used as control flow - -- mechanism. - Report.Failed - ("Specific raise did not alter program control" & - " from Resource_Limit_Exceeded"); - else - return (False); - end if; - exception - when others => - Reraised_In_Function := True; - raise; -- Exception propagated to caller. - Report.Failed ("Exception not propagated to caller" & - " from Resource_Limit_Exceeded"); - end Resource_Limit_Exceeded; - - - procedure Release is - begin - Count := Count + 1; -- Count of resources available - -- incremented. - if Resource_Limit_Exceeded then -- Call to protected operation - Count := Count - 1; -- function that raises/reraises - -- an exception. - Report.Failed("Resource limit exceeded"); - end if; - - exception - when others => - raise; -- Reraised and propagated again. - Report.Failed ("Exception not reraised by procedure Release"); - end Release; - - - end Counting_Semaphore; - -end CB20006_0; - - - --=================================================================-- - - -with CB20006_0; -- Package Semaphore. -with Report; - -procedure CB20006 is -begin - - Report.Test ("CB20006", "Check that exceptions are raised and " & - "handled / reraised and propagated " & - "correctly by protected operations" ); - - Test_Block: - declare - - package Semaphore renames CB20006_0; - - Total_Resources_Available : constant := 1; - - Resources : Semaphore.Counting_Semaphore (Total_Resources_Available); - -- An object of protected type. - - begin - - Allocate_Resources: - declare - Loop_Count : Integer := Total_Resources_Available + 1; - begin - for I in 1..Loop_Count loop -- Force exception - Resources.Secure; - end loop; - Report.Failed - ("Exception not propagated from protected operation Secure"); - exception - when Semaphore.Resource_Underflow => -- Exception propagated - Semaphore.Handled_In_Procedure_Caller := True; -- from protected - when others => -- procedure. - Semaphore.Handled_In_Procedure_Caller := False; - end Allocate_Resources; - - - Deallocate_Resources: - declare - Loop_Count : Integer := Total_Resources_Available + 1; - begin - for I in 1..Loop_Count loop -- Force exception - Resources.Release; - end loop; - Report.Failed - ("Exception not propagated from protected operation Release"); - exception - when Semaphore.Resource_Overflow => -- Exception propagated - Semaphore.Handled_In_Function_Caller := True; -- from protected - when others => -- function. - Semaphore.Handled_In_Function_Caller := False; - end Deallocate_Resources; - - - if not (Semaphore.Reraised_In_Procedure and - Semaphore.Reraised_In_Function and - Semaphore.Handled_In_Procedure_Caller and - Semaphore.Handled_In_Function_Caller) - then -- Incorrect excpt. handling - Report.Failed -- in protected operations. - ("Improper exception handling/reraising by protected operations"); - end if; - - exception - - when others => - Report.Failed ("Unexpected exception " & - " raised and propagated in test"); - end Test_Block; - - Report.Result; - - -end CB20006; |
