Re: [Py4j-users] A question about life cycle control of sockets in GatewayServer instance

[Barthelemy D. <ba...@cs...>]

Hi Jason,

If you are speaking of GatewayServer on the Java side, it is a bug. Sockets in the connections list should be removed once a GatewayConnection is closed. This will require a small refactoring because the gateway connection is closed in one thread and the shutdown method on the gatewayserver can be called in another thread.

Thanks for reporting this bug,
Barthélémy

This may be not good for this use case: the GatewayServer is providing a kind of service. Python clients connect to the GatewayServer, do some communication, close the connect and end the Python process, but not shutdown the server. After many times of this kind of connections, I see those socket objects are held in the "connections" list and not garbage collected.
