Daniel Felsing updated FELIX-642:
---------------------------------
Description:
Ok...overall problem is as follows:
upnp event delivery to OSGi event listeners fails on random devices after a
certain period of time
Overall Environment Setup
-------------------------
- i have two hosts A and B => A is a Bridge exporting about 20 devices at the
moment (will get more - it's a X10 like system), B acts as a central server for
the devices (Smart Home implementation)
- A is a SensorBridge...and B a central controlpoint importing all those devices
- both ends use upnpbasedriver 0.8 and extra bundle from felix project
- the two hosts are connected through a Gigabit Switch (NO WIRELESS USED!)
- all the devices on the server (so the central smart home controller) that get
imported get refined. They subscribe to the upnp device it refines to get
notified on event change.
- on the central server (Host B) i subscribe to UPnP Devices exported by Host A
using UPnPSubscriber Helper class of the extra bundle
Issues
------
- "SOMETIMES" on INITIAL subscription not all devices get notified about the
initial status (devices get found properly though)
( see also http://www.mail-archive.com/[EMAIL PROTECTED]/msg01781.html for
that)
- after some time of operation random devices begin to fail - that means..they
do not get notified about event changes anymore, but devices are still present
(so they are still there as UPnPDevice instances in the central server)...
=> i had debug enabled....and as i see i still receive the event-change
notifies on my Host B (=central server)....if i "resubscribe" to the event
listener of the failed device everything works again (i dont need to restart
the whole basedriver or osgi framework to let it work again - just my refining
driver must be restarted which does the subscription to the devices using
UPnPSubscriber class) ...
SO this STILL GETS DELIVERED, but listeners do not get notified about the
change:

Tests:
-----------------
- yes - every device exported by the upnpsensorbridge (=Host A) gets found by
the central server (=Host B)
- upnp tester of felix project experiences same issues
- the REFINED devices on the SERVER themselves are using the felix helper class
to subscribe to the events:
// create upnp listener - if evented is true
subscriber = new UPnPSubscriber(bundleContext, this);
subscriber.subscribeAllServicesOf(super.getUPnPDeviceUDN());
- i also tried: EventListener test = new EventListener();
servReg =
context.registerService(UPnPEventListener.class.getName(), test, null);
(so not using UPnPSubscriber) => same problem...so UPnPSubscriber may not be
the root of the problem
- the upnp device implementation on the host exporting the upnp devices ( =Host
A, sensorbridge) are using the following line to expose event notifier
// setup event notifier
notify_switch = new UPnPEventNotifier(context, this,
switchdevswitchservice, switchDev);

Is it possible that my issue is connected to this one mentioned in the
cyberlink forum?
