[Twisted-Python] [SOLVED] ProducerConsumerProxy problem

I found the solution. The problem was that by default our proxys producer is registered with streaming = True which is not what we want. The following line will register our proxys producer with streaming = False ProducerConsumerProxy.iAmStreaming = False The rest is the same. I think adding an argument to ProducerConsumerProxy.__init__ about streaming would be a good idea. proxy = ProducerConsumerProxy(self.client.transport) dd = FileSender().beginFileTransfer(self.outgoingFile, proxy) dd.addCallback(self.uploadDone) dd.addErrback(self.uploadError)
