The Delay --- Until statement is used to avoid accumulated drift. In this test --- three simple situations simulating the start of drift are used: the --- next pulse being called for at the normal time, the next pulse being --- called for at exactly the current time and then at some time which has --- already past. We assume the delay is within a While Loop and, to --- simplify the test, we "unfold" the While Loop and execute the Delays --- in a serial fashion. This loop is shown in test C960001. --- It is not possible to test the actual immediacy of the expiration. We --- can only check that it returns in a "reasonable" time. In this case --- we check that it expires before the next "pulse" should have been --- issued. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- ---! - -with Report; -with ImpDef; - -with Ada.Calendar; -with System; - -procedure C960002 is - -begin - - Report.Test ("C960002", "Simple Delay Until with requested time being" & - " ""now"" and time already in the past"); - - 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 : Ada.Calendar.Time; Right: Duration) - return Ada.Calendar.Time renames Ada.Calendar."-"; - function "-" (Left, Right : Ada.Calendar.Time) - return duration renames Ada.Calendar."-"; - function ">" (Left, Right : Ada.Calendar.Time) - return Boolean renames Ada.Calendar.">"; - - - task Pulse_Task is - entry Trigger; - end Pulse_Task; - - - -- Task to synchronize all qualified receivers. - -- The entry Trigger starts the synchronization. - -- - task body Pulse_Task is - Pulse_Time : Ada.Calendar.Time; - Pulse_Time_Delta : constant duration := ImpDef.Clear_Ready_Queue; - - - - TC_Time_Back : 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; - --------------- - -- normal calculation for "next" - Pulse_Time := Ada.Calendar.Clock + Pulse_Time_Delta; - - -- TC: unfold the "while" loop in C960001.
