Hi,
I'm trying to start my Ryu system by sending an event from one app to
another, but it keeps saying EVENT LOST when I use --verbose. I understand
from another thread that we need to wait a bit for the event pipeline to
open, so I put hub.sleep(5) but the problem persists.
My original code was:
*def start(self):*
* super(Initialization,self).start()
new_north_traffic_request_ev =
Custom_event.North_CrossDomainTrafficRequestEvent()*
* hub.sleep(5)*
* self.send_event('Test', new_north_traffic_request_ev)*
and inside North_CrossDomainTrafficRequestEvent(), I have a print statement
to see if the event was triggered by the sent event but it's not since we
have EVENT LOST.
(Specifically it says EVENT LOST Initialization->Test
North_CrossDomainTrafficRequestEvent).
I have also tried separating start into a separate function for the event,
and spawning a thread for that event, not sure if that helps, but I still
get EVENT LOST:
* def _north_request_event(self):*
* hub.sleep(5)*
* new_north_traffic_request_ev =
Custom_event.North_CrossDomainTrafficRequestEvent()*
* self.send_event('Test', new_north_traffic_request_ev)*
* def start(self):*
* super(Initialization,self).start()*
* self.threads.append(hub.spawn(self._north_request_event))*
Thank you,
Yiwen
