Esteve Fernandez commented on THRIFT-148:
-----------------------------------------
I'm not sure if EventMachine is the exact Ruby equivalent of Twisted, but both
implement the Reactor pattern and support
[Futures|http://en.wikipedia.org/wiki/Future_(programming)]
([Deferreds|http://twistedmatrix.com/documents/current/api/twisted.internet.defer.Deferred.html]
in Twisted-speak,
[Deferrables|http://rubyeventmachine.com/browser/trunk/docs/DEFERRABLES] in
EventMachine)
Here's what I did in the client code:
1 - maintain a dictionary of Deferreds in your Client, keyed on seqid
2 - whenever a method needs to return a value, return a Deferred instead
3 - read incoming messages in the dataReceived method (client protocol)
4 - when the consumeFrame method encounters a complete message, call the
appropiate recv_METHOD method in the client
5 - once the recv_METHOD method finishes, fire the Deferred
And this in the server code to support methods that return Deferreds:
1 - read incoming messages in the dataReceived method (server protocol)
2 - when the consumeFrame method encounters a complete message, call the
Processor's process method
3 - wrap the self._handler.METHOD in a Deferred (with maybeDeferred)
4 - add a callback (and an errback if the method is supposed to throw an
exception) to the previous Deferred
