Is it possible to use tornado's gen.engine and gen.Task with twisted?

Question

The project I am working on is all written in Tornado, but I have included a bit of Twisted to deal with asynchronous XML-RPC. I was wondering if you can use Tornado\'s gen.engi

Answer 1

I modified Ben's sample code a bit in order to set exception correctly.

def wrap_deferred(deferred):
    future = tornado.concurrent.TracebackFuture()
    deferred.addCallback(future.set_result)
    deferred.addErrback(lambda err: future.set_exception(err.value))
    return future

twisted wrap exception as a failure.Failure. future.set_exception complains it is not an exception type.
