At the same time another bunch of --- of tasks are queued on the single entry of protected object --- Holding_Pen. --- Once all the tasks have had time to block, the main procedure --- opens all the entries for Main_PO by calling the --- Start_Protected_Operation protected procedure. This should --- process all the pending callers as part of a single protected --- operation. --- During this protected operation, the entries of Main_PO release --- the tasks blocked on Holding_Pen by calling the protected --- procedure Release. --- Once released from Holding_Pen, the task immediately calls --- an entry in Main_PO. --- These new calls should not gain access to Main_PO until --- the initial protected operation on that object completes. --- The order in which the entry calls on Main_PO are taken is --- recorded in a global array and checked after all the tasks --- have terminated. --- --- --- CHANGE HISTORY: --- 25 OCT 95 SAIC ACVC 2.1 --- 15 JAN 95 SAIC Fixed deadlock problem. --- ---! - -with Report; -procedure C953002 is - Verbose : constant Boolean := False; - - Half_Tasks : constant := 15; -- how many tasks of each group - Max_Tasks : constant := Half_Tasks * 2; -- total number of tasks - - Note_Order : array (1..Max_Tasks) of Integer := (1..Max_Tasks => 0); - Note_Cnt : Integer := 0; -begin - Report.Test ("C953002", - "Check that the servicing of entry queues handles all" & - " open entries as part of a single protected operation"); - declare - task type Assault_PO is - entry Take_ID (Id : Integer); - end Assault_PO; - - First_Wave : array (1 ..
