"RED is build upon"

The protocol handler emit's message events, these needs to be handled and executed. Every message based event should be emitted to RED RED#emit. Blacklisted event and those who start with the this.namespace should be ignored. The blacklisted events would initially include ['error']

• message -> emit the message event
• codec -> emit the message event
• event -> emit the event.name event with the arguments

The rest of the event should be handled by RED.

There is a race condition in either engine.js or in the test suite. The incorrect connection host test fails because it throws an uncaught exception. For some odd reason, it's not captured by our error handlers or it's just not capture correctly in node_redis

The streaming protocol parser is failing randomly. It seems that the ProtocolStream#destroy is called to early before we could parse all the messages.

Description

When we send a message we are now calling engine#publish which does a publish to all connected nodes. When you cluster is growing in size (nodes) this will create a lot of pointless overhead because node's that doesn't have user connected will also receive this message.

Possible solutions

• When a user connects to a RED node, we are going to store the hostname and process id and put that in Redis. So when we need to send a message to that user, we can fetch the sessions connected nodes and only broadcast to those. This probably also requires the engine to listen to another for dedicated messaging`

Providing hooks for DTraces gives a greater insight in the working on the server. Adding hooks also helps us to get metrics out of the applications that are using this.
