[Twisted-Python] Catching error in protocol.ReconnectingClientFactory

[Martin]

Hi, thanks for your reply.

Indeed, the ReconnectingClientFactory is being sent the Failure object to

def clientConnectionLost(self, connector, reason):
         log.msg('Lost connection. Reason: %s' % reason)
         protocol.ReconnectingClientFactory.clientConnectionLost(self, 
connector, reason)

where "reason" is the Failure object that is "unhandled". is there 
anything I could do to it there to make it handled?

Also, the documentation in 
http://twistedmatrix.com/documents/current/core/howto/defer.html says 
that one can do d.addErrback(err.log) to deal with unhandled errors, but 
what is d?

In general, I'm not doing anything special.. I'm creating a 
ReconnectingClientFactory and connecting it to a server..
f = MyReconnectingClientFactory(..)
reactor.connectSSL(url, port, f, ssl.ClientContextFactory())
reactor.run()

Basically it. Any thoughts? Thanks a lot!

> These messages are coming from some code which is issuing Deferreds, not from ReconnectingClientFactory.  You need to add an errback to those Deferreds in your application code.  There's no way to write a catch-all, just like there's no way to write a catch-all that can stop exceptions from being raised in basic Python.
