So is the idiomatic approach for this with something like the FTPClient
to
subclass it and override connectionLost? FTPClientBasic clears up
queued
commands when this happens (which I assume I still want it to do).
Is it idiomatic? I don't know. It accomplishes your goal. If you
like, propose a better API (file a ticket, attach a patch, etc:

)

To me it seems a little overbearing to have to subclass the ftpclient
just
to get a tcp connection lost event (which seem like an event most users
would be interested in).

I am writing a simple ftp client which I am trying to dispose of.
Right
now
I send a quit command:
(the ftp_client reference is a FTPClient built with a ClientCreator)
deferred = ftp_client.quit()
And I register a callback:
def quitSent(response):
print "quit acknowledged...connected?",
ftp_client.transport.connected
deferred.addCallback(quitSent)
If I invoke the above the connection is printed as connected.
There is no documented `connected` attribute of transports. So who
knows
what this is telling you. :)
However, the way you learn when a protocol's transport has
disconnected is
to implement the `connectionLost` method on the protocol. It is
called
when the transport disconnects.

However if I schedule a callback to check the status later:
def status():
print "quit acknowledged...connected?",
ftp_client.transport.connected
reactor.callLater(1, self.status)
If I schedule a callback for a second later the transport is not
connected.
I've searched quite a bit but I cannot determine a way to register a
callback for when the TCP transport is actually disconnected. Can
anyone
offer some insight? I'd like to know explicitly when the client is
closed.
Thanks,
Peter
