Hey,

You forgot the "yield" from the WaitForSignal op. The code should be:

def myaction(self):
    yield request.environ['cogen.core'].events.WaitForSignal("abc", timeout=5)
    if isinstance(request.environ['cogen.wsgi'].result, Exception):
        yield "Timed out..."
    else:
        yield "Got signal %s" % request.environ['cogen.wsgi'].result

Please use the mailing list for further inquires.

Hi Ionel, I hope you have time to answer a simple Cogen question for me.

I'm using Pylons and I want to do something like this within a controller:

def myaction(self):
    request.environ['cogen.core'].events.WaitForSignal("abc", timeout=5)
    if isinstance(request.environ['cogen.wsgi'].result, Exception):
        yield "Timed out..."
    else:
        yield "Got signal %s" % request.environ['cogen.wsgi'].result

I will later rely on another coro to fire the signal 'abc'.  But right now nobody is firing that signal, but it still goes directly to:

    "Got signal None"

My expected behavior is that it will wait for 5 seconds (since the timeout is 5) and then go "Timed out".

Any idea what I am doing wrong?

Kind regards,
Torbjorn
