A watchdog timer should be set for move and action requests so the client does not lock up waiting for a response #111

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The assumption that the server will send a response to the client after a 
move or action XML request is not valid.  A watchdog timer should be set 
when the response is sent.

This error has occurred and results in a non-responsive client that is 
locked waiting for the response from the server.

If the assumption is then made that a request-response pair is not guaranteed 
to match all requests need to have a unique ID that is sent with 
the response.  This way a response that is simply sent late does not interfere 
with future move and action messages.

The client may want to have a mechanism for confirming that the action 
request has been executed.  Alternatively a non-response could be treated 
as a failed action or move.  This second option should be easier to 
implement.  The failed response does not occur very often and should not 
pose a major problem in game play.
