In particular, check the case of +-- the ATC in non-tasking code. +-- +-- TEST DESCRIPTION: +-- A fraction of in-line code is simulated. An asynchronous select +-- is used with a triggering delay of several minutes. The abortable +-- part, which is simulating a very lengthy, time consuming procedure +-- actually returns almost immediately thus ensuring that it completes +-- first. At the conclusion, if a substantial amount of time has passed +-- the delay is assumed not to have been cancelled. +-- (based on example in LRM 9.7.4) +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + + +with Report; +with Ada.Calendar; + +procedure C974014 is + + function "-" (Left, Right : Ada.Calendar.Time) + return Duration renames Ada.Calendar."-"; + + TC_Start_Time : Ada.Calendar.Time := Ada.Calendar.Clock; + TC_Elapsed_Time : duration; + + Maximum_Allowable_Time : duration := 300.0; -- for Calculate_Gamma_Function + +begin + + Report.Test ("C974014", "ATC: When abortable part completes before " & + "a triggering delay, check that the delay " & + "is cancelled & optional statements " & + "are not performed"); + + declare -- encapsulate test code + + type Gamma_Index is digits 5; -- float precision + + -- (These two fields are assumed filled elsewhere) + Input_Field, Result_of_Beta : Gamma_Index; + + -- Notify and take corrective action in the event that + -- the procedure Calculate_Gamma_Function does not converge. + -- + procedure Non_Convergent is + begin + null; -- stub + + Report.Failed ("Optional statements in triggering part" & + " were performed"); + end Non_Convergent; + + + -- This is a very time consuming calculation.
