The first part of this test mirrors +-- that example. The second part of the test expands upon +-- the example code to add an object with finalization code +-- to the protected object. The finalization code should be +-- executed after Program_Error is raised in the callers left +-- on the entry queues. +-- +-- +-- CHANGE HISTORY: +-- 08 Jan 96 SAIC Initial Release for 2.1 +-- 10 Jul 96 SAIC Incorporated Reviewer comments to fix race +-- condition. +-- +--! + + +with Ada.Finalization; +package C940014_0 is + Verbose : constant Boolean := False; + Finalization_Occurred : Boolean := False; + + type Has_Finalization is new Ada.Finalization.Limited_Controlled with + record + Placeholder : Integer; + end record; + procedure Finalize (Object : in out Has_Finalization); +end C940014_0; + + +with Report; +with ImpDef; +package body C940014_0 is + procedure Finalize (Object : in out Has_Finalization) is + begin + delay ImpDef.Clear_Ready_Queue; + Finalization_Occurred := True; + if Verbose then + Report.Comment ("in Finalize"); + end if; + end Finalize; +end C940014_0; + + + +with Report; +with ImpDef; +with Ada.Finalization; +with C940014_0; + +procedure C940014 is + Verbose : constant Boolean := C940014_0.Verbose; + +begin + + Report.Test ("C940014", "Check that the finalization of a protected" & + " object results in program_error being raised" & + " at the point of the entry call statement for" & + " any tasks remaining on any entry queue"); + + First_Check: declare + -- example from ARM 9.4(20a-f);6.0 with minor mods + task T is + entry E; + end T; + task body T is + protected PO is + entry Ee; + end PO; + protected body PO is + entry Ee when Report.Ident_Bool (False) is + begin + null; + end Ee; + end PO; + begin + accept E do + requeue PO.Ee; + end E; + if Verbose then + Report.Comment ("task about to terminate"); + end if; + end T; + begin -- First_Check + begin + T.E; + delay ImpDef.Clear_Ready_Queue; + Report.Failed ("exception not raised in First_Check"); + exception + when Program_Error => + if Verbose then + Report.Comment ("ARM Example passed"); + end if; + when others => + Report.Failed ("wrong exception in First_Check"); + end; + end First_Check; + + + Second_Check : declare + -- here we want to check that the raising of Program_Error + -- occurs before the other finalization actions. + task T is + entry E; + end T; + task body T is + protected PO is + entry Ee; + private + Component : C940014_0.Has_Finalization; + end PO; + protected body PO is + entry Ee when Report.Ident_Bool (False) is + begin + null; + end Ee; + end PO; + begin + accept E do + requeue PO.Ee; + end E; + if Verbose then + Report.Comment ("task about to terminate"); + end if; + end T; + begin -- Second_Check + T.E; + delay ImpDef.Clear_Ready_Queue; + Report.Failed ("exception not raised in Second_Check"); + exception + when Program_Error => + if C940014_0.Finalization_Occurred then + Report.Failed ("wrong order for finalization"); + elsif Verbose then + Report.Comment ("Second_Check passed"); + end if; + when others => + Report.Failed ("Wrong exception in Second_Check"); + end Second_Check; + + + Report.Result; + +end C940014; |
