You might be interested to know that Koo beta 3 includes a Subscription
mechanism (needs 'ktiny' server module installed, too) that avoids polling
the server at fixed time intervals and can be used with XML-RPC, Net-RPC or
Pyro protocols.
The API in the client side is extremely simple and we're already using it for
keeping data up to date the whole time: you can see the list view refreshed
when partners are added, removed or modified without the need of a fixed time
interval.
So writing a plugin that notifies on incomming calls would be something as
simple as:
---------
self.subscriber = Rpc.Subscriber(Rpc.session, self)
self.subscriber.subscribe( 'updated_model:asterisk.phone', self.notify )
def notify(self):
QMessageBox.information( self, _("Phone call"), _("You're being
called!") )
---------
Well, I think you get the idea. The notify function would be called each time
a record was added, modified or removed from the "asterisk.phone" model. Of
course, it could be improved on the server side and use the even smaller
publishing API provided by 'ktiny' module. Something like this would do:
netsvc.LocalService('subscription').publish( 'new_phone_call' )
And subscribe on the client appropiately.
Note that the method used is not '100%' bug free and some events could be lost
if the interval between them is very short, but I'd say it works as expected
99% of the time, and should definitely work for the asterisk case. If it
would be integrated in OpenERP core server, it could be benefit from other
optimisations too.
