• create a smith based net/rpc codec. simulate the following two apis
  • codec.MsgpackSpecRpc.ClientCodec -- done
  • codec.MsgpackSpecRpc.ServerCodec
• pubsub in go-smith
  • net/rpc doesn't cover this. It's required to create a server to receive calls.
• encoding/transportation conversion
  • encoding:
    • json/msgpack gateway.
  • transportation
    • smith/sockjs gateway.
• bring this implementation to sockjs -->
  • sockjs with callback support
  • can sockjs used as transportation of net/rpc?

this looks interesting http://www.gorillatoolkit.org/pkg/rpc but how to support pubsub?

In smith, a specific seq ID 9999 is chosen to represent event message published from server.
Go's RPC client can't catch this since it's a unsolicited message. That's means its a response without previous correspondent request.

no easy way to archive pubsub.

• Bidirectional RPC: http://rogpeppe.wordpress.com/2011/02/10/bidirectional-rpc-with-netchan/
  • Is simulating Publish by making RPC Call a good idea?
  • RPC Server's semantics doesn't match a subscriber's behavior. A subscriber seldom returns value.
• Stream Tap -- done
  • ugly hack
  • it works.

Beego has official example on how to integrate with sockjs
