Check --- that the delay does not complete before the requested time and that it --- does complete thereafter --- --- TEST DESCRIPTION: --- Simulate a task that sends a "pulse" at regular intervals. The Delay --- Until statement is used to avoid accumulated drift. For the --- test, we expect the delay to return very close to the requested time; --- we use an additional Pulse_Time_Delta for the limit. The test --- driver (main) artificially limits the number of iterations by setting --- the Stop_Pulse Boolean after a small number. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- 15 Nov 95 SAIC Fixed global variable problem for ACVC 2.0.1 --- ---! - -with Report; -with Ada.Calendar; -with ImpDef; - -procedure C960001 is - -begin - - Report.Test ("C960001", "Simple Delay Until"); - - declare -- To get the Report.Result after all has completed - - function "+" (Left : Ada.Calendar.Time; Right: Duration) - return Ada.Calendar.Time renames Ada.Calendar."+"; - function "<" (Left, Right : Ada.Calendar.Time) - return Boolean renames Ada.Calendar."<"; - function ">" (Left, Right : Ada.Calendar.Time) - return Boolean renames Ada.Calendar.">"; - - TC_Loop_Count : integer range 0..4 := 0; - - - -- control over stopping tasks - protected Control is - procedure Stop_Now; - function Stop return Boolean; - private - Halt : Boolean := False; - end Control; - - protected body Control is - procedure Stop_Now is - begin - Halt := True; - end Stop_Now; - - function Stop return Boolean is - begin - return Halt; - end Stop; - end Control; - - task Pulse_Task is - entry Trigger; - end Pulse_Task; - - - -- Task to synchronize all qualified receivers. - -- The entry Trigger starts the synchronization; Control.Stop - -- becoming true terminates the task. - -- - task body Pulse_Task is - - Pulse_Time : Ada.Calendar.Time; - - Pulse_Time_Delta : duration := ImpDef.Clear_Ready_Queue; - - TC_Last_Time : Ada.Calendar.Time; - TC_Current : Ada.Calendar.Time; - - - -- This routine transmits a synchronizing "pulse" to - -- all receivers - procedure Pulse is - begin - null; -- Stub - Report.Comment (".......PULSE........"); - end Pulse; - - begin - accept Trigger; - - Pulse_Time := Ada.Calendar.Clock + Pulse_Time_Delta; - TC_Last_Time := Pulse_Time; - - while not Control.Stop loop - delay until Pulse_Time; - Pulse; - - -- Calculate time for next pulse.
