Test control code has been added to the --- procedures such that, whichever gets called first executes a lengthy --- calculation giving sufficient time (on a multiprocessor or a --- time-slicing machine) for the other task to get control and call the --- other procedure. The control code verifies that entry to the second --- routine is postponed until the first is complete. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- ---! - -with Report; -with ImpDef; - -procedure C951001 is - - protected Ramp_31 is - - procedure Add_Meter_Queue; - procedure Subtract_Meter_Queue; - function TC_Failed return Boolean; - - private - - Ramp_Count : integer range 0..20 := 4; -- Start test with some - -- vehicles on the ramp - - TC_Add_Started : Boolean := false; - TC_Subtract_Started : Boolean := false; - TC_Add_Finished : Boolean := false; - TC_Subtract_Finished : Boolean := false; - TC_Concurrent_Running: Boolean := false; - - end Ramp_31; - - - protected body Ramp_31 is - - function TC_Failed return Boolean is - begin - -- this indicator will have been set true if any instance - -- of concurrent running has been proved - return TC_Concurrent_Running; - end TC_Failed; - - - procedure Add_Meter_Queue is - begin - --================================================== - -- This section is all Test_Control code - TC_Add_Started := true; - if TC_Subtract_Started then - if not TC_Subtract_Finished then - TC_Concurrent_Running := true; - end if; - else - -- Subtract has not started. - -- Execute a lengthy routine to give it a chance to do so - ImpDef.Exceed_Time_Slice; - - if TC_Subtract_Started then - -- Subtract was able to start so we have concurrent - -- running and the test has failed - TC_Concurrent_Running := true; - end if; - end if; - TC_Add_Finished := true; - --================================================== - Ramp_Count := Ramp_Count + 1; - end Add_Meter_Queue; - - procedure Subtract_Meter_Queue is - begin - --================================================== - -- This section is all Test_Control code - TC_Subtract_Started := true; - if TC_Add_Started then - if not TC_Add_Finished then - -- We already have concurrent running - TC_Concurrent_Running := true; - end if; - else - -- Add has not started. - -- Execute a lengthy routine to give it a chance to do so - ImpDef.Exceed_Time_Slice; - - if TC_Add_Started then - -- Add was able to start so we have concurrent - -- running and the test has failed - TC_Concurrent_Running := true; - end if; - end if; - TC_Subtract_Finished := true; - --================================================== - Ramp_Count := Ramp_Count - 1; - end Subtract_Meter_Queue; - - end Ramp_31; - -begin - - Report.Test ("C951001", "Check that two procedures in a protected" & - " object will not be executed concurrently"); - - declare -- encapsulate the test - - task Vehicle_1; - task Vehicle_2; - - - -- Vehicle_1 and Vehicle_2 are simulations of Instances of the task - -- of type Vehicle in different stages of execution - - task body Vehicle_1 is - begin - null; -- ::::: stub. preparation code - - -- Add to the count of vehicles on the queue - Ramp_31.Add_Meter_Queue; - - null; -- ::::: stub: wait at the meter then pass to first sensor - - -- Reduce the count of vehicles on the queue - null; -- ::::: stub: Ramp_31.Subtract_Meter_Queue - exception - when others => - Report.Failed ("Unexpected Exception in Vehicle_1 task"); - end Vehicle_1; - - - task body Vehicle_2 is - begin - null; -- ::::: stub. preparation code - - -- Add to the count of vehicles on the queue - null; -- ::::: stub Ramp_31.Add_Meter_Queue; - - null; -- ::::: stub: wait at the meter then pass to first sensor - - -- Reduce the count of vehicles on the queue - Ramp_31.Subtract_Meter_Queue; - exception - when others => - Report.Failed ("Unexpected Exception in Vehicle_2 task"); - end Vehicle_2; - - - - begin - null; - end; -- encapsulation - - if Ramp_31.TC_Failed then - Report.Failed ("Concurrent Running detected"); - end if; - - Report.Result; - -end C951001; |
