Streaming handlers do not work

[utrack]

Here's the screenshot from micro web:

It's odd that meta has stream=false as well.

Woops, nevermind. The client itself works.

Can you specify what you mean by "streaming handler's metadata is empty"?

So looks like the streaming handler does work but its incorrectly registering stream=false. The code that takes care of this uses reflection and I'm thinking perhaps a new version of Go behaves slightly differently.

If you run the client you should get this output

go run client/main.go

@asim sorry, bad wording. I meant that the Request and Response helper fields are empty when trying to get the service's metadata.
Also, micro tool can't query the streaming endpoints. I'll try to fix that.

decb70b fixed metadata issue.

The micro tool can handle streams using the micro stream command but it only supports streaming from the server. Useful for logs and events. Bidirectional streaming from the command line seems difficult given the output would be streaming to you at the same time.

[asim]

On the Request and Response being empty. Its because we use the method signature to determine what those types are. In this case, the Stream is an interface rather than a concrete type.
