[Twisted-Python] Logout from a perspective broker server
Hi all, I wonder, if I client using pygtk, can logout from the server without calling reactor.stop(), as you would kill the GUI. I tried to delete the perspective got from the server but it does not work...

The simplest thing you can do to achieve this is 'broker.transport.loseConnection()'. Of course, that just unceremoniously drops the connection. You may want to have a 'remote_disconnect' method on the server too, if you have any state you would like to cleanly finish up with first. Your GUI is already handling disconnection due to network problems though, right? :-) So the modification to make it handle this slightly-cleaner disconnect should be minor. If it doesn't, see the notifyOnDisconnect API in PB: <http://twistedmatrix.com/documents/10.0.0/api/twisted.spread.pb.Broker.html#...>.
Glyph,

After having a look at pb.py code I used factory = pb.PBClientFactory() .... factory.disconnect() Then this makes the server call a 'logout' method for the current perspective, and makes a clean logout. Any comment?

Yeah. I was already using it. Very nice. I also wanted to enable a way to conecct and disconnect from the client, apart from the client be aware of a server restart on simply loosing connection. It works cleanly. Really grateful for your info and comments Regards
