[jdev] How is a client crash communicated to the XMPP server?

[Jonathan Dickinson]

Unfortunately not all clients are 100% XMPP compliant. I am certain that most will give you a </stream:stream> at the end: so if a client disconnects without that they /should/ have quit unexpectedly.

Conversant XMPP Communicator:

</stream:stream>

Coccinella:

<presence type='unavailable'/>

</stream:stream>

As you can see Coccinella behaves as a client should, but both send the </stream:stream> so you should be able to tell with that.

So:

Client sends </stream:stream>
   o Disconnect client
   o Client disconnected normally
Client disconnects
   o Abandon client
   o Client disconnected unexpectedly
