ko1 fd7ac9f3c9 * thread_tools.c: add Queue#close(exception=false) and ... SizedQueue#close(exception=false). [Feature #10600] Trying to deq from a closed empty queue return nil if exception parameter equals to false (default). If exception parameter is truthy, it raises ClosedQueueError (< StopIteration). ClosedQueueError inherits StopIteration so that you can write: loop{ e = q.deq; (using e) } Trying to close a closed queue raises ClosedQueueError. Blocking threads to wait deq for Queue and SizedQueue will be restarted immediately by returning nil (exception=false) or raising a ClosedQueueError (exception=true). Blocking threads to wait enq for SizedQueue will be restarted by raising a ClosedQueueError immediately. The above specification is not proposed specification, so that we need to continue discussion to conclude specification this method. * test/thread/test_queue.rb: add tests originally written by John Anderson and modify detailed behavior. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51699 b2dd03c8-39d4-4d8f-98ff-823fe69b080e		2015-08-26 22:59:32 +00:00
