I have a Client that currently does the following:
- connects
- collects some data locally
- sends that data to a server
- repeats
- if disconnected, reconnects and continues the above (not shown)
Like this:
def do_send(self):
def get_data():
# do something
return data
def send_data(data)
self.sendMessage(data)
return deferToThread(get_data).addCallback(send_data)
def connectionMade(self):
WebSocketClientProtocol.connectionMade(self)
self.sender = task.LoopingCall(self.do_send)
self.sender.start(60)
However, when disconnected, I would like the data collection to continue, probably queuing and writing to file at a certain limit. I have reviewed the DeferredQueue object which seems like what I need, but I can't seem to crack it.
In pseudo-code, it would go something like this:
queue = DeferredQueue
# in a separate class from the client protocol
def start_data_collection():
self.collecter = task.LoopingCall(self.get_data)
self.sender.start(60)
def get_data()
# do something
queue.put(data)
Then have the client protocol check the queue, which is where I get lost. Is DeferredQueue what I need, or is there a better way?
