UPnP Plugin device tracking is error-prone
------------------------------------------
Key: FELIX-3426
URL: https://issues.apache.org/jira/browse/FELIX-3426
Project: Felix
Issue Type: Bug
Components: Web Console
Affects Versions: webconsole-upnp-plugin-1.0.0
Reporter: Valentin Valchev
Assignee: Valentin Valchev
Priority: Critical
Fix For: webconsole-upnp-plugin-1.0.2
Sometimes, when one device appears, and another is removed, the plugin is
unregistered. The reason is that the addingService() and removedService() in
the activator are not synchronized.
In addition, in removedService() the code fragment is absolutely incorrect:
if (tracker.getTrackingCount() == 0 && plugin != null)
{
plugin.unregister();
this.plugin = null;
}
The reason is that 'tracking count' is always incremented - no matter if a
service is registered, modified or unregistered. It is NOT the count of tracked
services.
