The + race occurs in the following scenario: + + - the handler is added to the reactor as soon as the connection + is established + - the server crashes and a thread waiting on the reactor closes + down the connection. As the connection handler and transports + have not been ref counted (yet) they could be completely + destroyed. + - the thread that initiated the connection would try to + duplicate a null transport and try adding that to cache and + all hell would break loose. + + The methodology adopted is to delay adding the handler to the + reactor till the handler is added to cache. This would make sure + that the transport is refcounted and hence the thread making the + connection will have a valid pointer to take action and do the + cleanup when it finds that the connection is closed. + + Fri Apr 12 14:14:01 2002 Balachandran Natarajan <bala@cs.wustl.edu> + + * tao/Connector_Registry.cpp: + * tao/Connector_Registry.h: + * tao/Connector_Registry.i: Added a new method, get_connector () + which returns a TAO_Connector based on a TAO_Endpoint.
