CPP2 Out of order responses with THeader "not" working about fbthrift HOT 3 CLOSED

Out of order is on by default for a cpp2 client + cpp2 server, you don't have to do anything to enable it. There are examples in unittests, e.g. https://github.com/facebook/fbthrift/blob/master/thrift/lib/cpp2/test/ThriftServerTest.cpp
THeaderProtocolFactory and THeaderTransportFactory are cpp1 classes, you don't need to use them. Perhaps the crashes are exactly because of this.

Thanks for the clarification. I removed those instantiations as you mentioned. In my client, I also made sure that all the TAsyncSocket operations including init are happening in the event base thread which is separate from the main thread. My ThriftServer initialization looks like the following. Note that there is a "handler" variable which belongs to a handler implementing the "Ping" call which echoes back the string:

unique_ptr handler(new PingHandler);
shared_ptrapache::thrift::ThriftServer server(new
apache::thrift::ThriftServer);
cout << "Server created..";
handler->setServer(server.get());
server->setInterface(unique_ptr(handler.release()));
server->setPort(port);
cout << "Serving at port " << port << endl;
server->serve();

Now, when I run the client against this server in async mode using a single connection - I get "Channel is !good" and the requestError() function in my RequestCallback is being invoked. The socket is getting created which means that the connection is going through. Is there something else I am missing - the example you gave contains some things around building/passing a ThreadManager but I thought that wont be necessary and that we would use one EventBase for accepting and Cpp2Workers (as many as cores) for running the calls in an event driven fashion. Any help would be really appreciated..

Seems like there was another issue - I tested the duplex pipeline with multiple threads and it works ! Thanks !
