copied!<p>Yes, you should add these processes to the supervision heirarchy as you want them to be correctly/gracefully shutdown when your application is stopped. (Otherwise you end up leaking connections that will fail as the application infrastructure they depend on been shutdown).</p> <p>You could create a <code>simple_one_for_one</code> strategy supervisor say <code>yourapp_client_sup</code> that has a child spec of <code>{Id, {yourapp_client_connection, start_link_with_socket, []}, Restart, Shutdown, worker, temporary}</code>. The <code>temporary</code> type here is important because there's normally no useful restart strategy for a connection handler - you can't connect out to the client to restart the connection. <code>temporary</code> here will cause the supervisor to report the connection handler exit but otherwise ignore it.</p> <p>The process that does <code>gen_tcp:accept</code> will then create the connection handler process by doing <code>supervisor:start_child(yourapp_client_sup, [Socket,Options,...])</code> rather than <code>yourapp_client_sup:start_link(Socket, Options, ...)</code>. Ensure that the <code>youreapp_client_connection:start_link_with_socket</code> function starts the child via <code>gen_server</code> or <code>proc_lib</code> functions (a requirement of the <code>supervisor</code> module) and that the function transfers control of the socket to the child with <code>gen_tcp:controlling_process</code> otherwise the child won't be able to use the socket.</p> <p>An alternate approach is to create a dummy <code>yourapp_client_sup</code> process that <code>yourclient_connection_handler</code> processes can link to at startup. The <code>yourapp_client_sup</code> process will just exist to propagate <code>EXIT</code> messages from its parent to the connection handler processes. It will need to trap exists and ignore all <code>EXIT</code> messages other than those from its parent. On the whole, I prefer to use the <code>simple_one_for_one</code> supervisor approach.</p>
