Hi all,
I'm sure I asked this question before, but I can't find any answers on
google, and I've changed my work flow a bit now, so thought it was worth
re-asking.
So on my server's protocol, I have a send method. This allows me to pass
arguments which get sent off to the client in the right format. The send
method looks something like this:
def send(self, command, **kwargs):
"""Cause the client to issue getattr(connection, command)(**kwargs).
If disconnect evaluates to True, disconnect the client after the message
is sent."""
disconnect = kwargs.get('disconnect', False)
try:
del kwargs['disconnect']
except KeyError:
pass # Argument not found.
d = defer.Deferred()
d.addCallback(self.prepare_command) Convert the command and kwargs to
json.
d.addCallback(self.deferred_write) # Write the json to the transport.
if disconnect:
d.addCallback(self.deferred_disconnect) # Issue
self.transport.loseConnection().
reactor.callFromThread(d.callback, [command, kwargs]) # Call the
deferred's callback chain.
return d # Return the deferred.
If I try something like:
protocol.send('alert', message = '*** Disconnected. ***', disconnect = True)
the client gets disconnected, but never sees the "*** Disconnected. ***"
message.
I guess I could do a reactor.callLater and just wait for the transport
to get the message, but that seems sloppy, and I can't help thinking
there must be something I'm missing.
Any ideas welcome!
Cheers all,
