[Twisted-Python] how to ensure writes to stdout via stdio.StandardIO are completed before we shutdown the reactor?
Hi twisted community, What’s the best way to ensure writes to stdout via stdio.StandardIO are completed before we shutdown the reactor? The use case is to emit an error message before we shutdown the reactor and stop our program. Dummy code snippet: -------------------------------------------- #!/usr/bin/python from twisted.internet import reactor, stdio from twisted.protocols.basic import LineReceiver class StdinInteractor(LineReceiver): delimiter = '\n' def go(): stdio_proto = StdinInteractor() stdio.StandardIO(stdio_proto) stdio_proto.transport.write('did we get this message?\n') if 0: reactor.stop() else: reactor.callLater(1.0, reactor.stop) reactor.callWhenRunning(go) reactor.run() -------------------------------------------- If I change ‘if 0’ to ‘if 1’, I don’t get the message on stdout. The ‘reactor.callLater(1.0, reactor.stop)’ is obviously a hack to let the reactor send out the buffered message before shutting down. Any ideas? Thanks, -- Benjamin Rutt
