Seems HostMetaApiService does not work for method (topic) registration

[nj4x]

Hello, Elad.

Please use this gist: https://gist.github.com/nj4x/dab94f833ca1e973623b to reproduce my case.

(WampSharp 1.2.4.111-dev)

Hi Roman,

This seems to work fine with Json serialization but doesn't work with msgpack serialization. I think it is related to the way I serialize DateTime in Newtonsoft.Msgpack.

I will try to investigate this further during the weekend.

Ok - the problem is that Newtonsoft.Msgpack serializes DateTime as a number (like msgpack-cli does) and after that WampSharp deserializes the object first into a JToken and later to a RegistrationDetails, but now when JTokenReader occurs a number, it doesn't attempt to convert it into a DateTime.

It seems that crossbar sends DateTime as a string, which is less compact but seems more compatible (other WAMP implementations might not know how to convert a number to a DateTime). I guess we should add an option to Newtonsoft.Msgpack MessagePackReader to write DateTime as string and use it in WampSharp.

Ok, I've removed MsgpackSerialization from that example and put JsonSerialization instead. Now it does not work (RPC un-register) when using RawSocketTransport (for Callee) instead of WebSocketTransport: https://gist.github.com/nj4x/92c118ed9ca57461755a

Hi,

I'm not sure why the router doesn't detect the client disconnection. Adding auto-pings eventually fixes this. (Set the autoPingInterval of the RawSocketTransport)

I'm not sure why an exception doesn't occur on the router side when the client disconnects without this.

Added AutoPing(TimeSpan.FromSeconds(2)) - did not help. Subsequent RPC registrations also does not work:
.. Main ..
CheckRegistrationEvent();
CheckRegistrationEvent();

Yeah, that's because you need to add to router side (so the router will detect disconnection):

defaultWampHost.RegisterTransport(new RawSocketTransport(new TcpListener(8090), autoPingInterval: TimeSpan.FromSeconds(20)), new JTokenJsonBinding(), new JTokenMsgpackBinding());

[darkl]

Ok, got it - ReadAsync returns 0 if the end of the stream has been reached. Will try to fix this.

Hi Roman,

Just released a new version to MyGet with a fix. Should work also without auto-pings :)

Thanks, Elad.

MetaApiService works on RawSocketTransport/JsonSerialization now.

Hi Roman,
I released today a version of Newtonsoft.Msgpack with a fix, and a version of WampSharp to MyGet feed. Should work now also with MsgPack serialization.

Thank you very much, Elad.
It works like expected.
