Subject [jira] [Commented] (QPID-5389) ConnectionHandler may stop writting pending frames if close is called right after the connection is started
Date Tue, 03 Dec 2013 23:55:36 GMT

    [ https://issues.apache.org/jira/browse/QPID-5389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13838354#comment-13838354
] 

Xin Chen commented on QPID-5389:
--------------------------------

This can be repro'ed by creating/closing connection is a loop:
      factory = ConnectionFactoryImpl.createFromURL(connectionUri);
      System.out.println("Started...");
      for (int i = 0; i < 10; i++)
      {
        System.out.println("creating conn " + i);
        connection = factory.createConnection();
        System.out.println("starting conn " + i);
        connection.start();
        System.out.println("stopping conn " + i);
        connection.stop();
        System.out.println("closing conn " + i);
        connection.close();
        System.out.println("closed conn " + i);
      }

> ConnectionEndpoint._closedForOutput is set to true when close is called. Right now HeaderBytesSource.closed()
returns false but _buffer has been completely consumed, which results in a deadloop in writing
this 0-length buffer. Regardless of this value, the connection handler should write out all
pending frames in the queue.
