Simple Fortune Cookie Protocol
Simple fortune cookie protocol handler, that emits a fortune cookie (at 40 characters/second) then disconnects.
A simple server that accepts connections on port 1500, sending a fortune cookie to any client that connects:
>>> SimpleServer(protocol=FortuneCookieProtocol, port=1500).run()
On a unix/linux client:
> telnet <server ip> 1500 Trying <server ip>... Connected to <server ip>... "I love Saturday morning cartoons, what classic humour! This is what entertainment is all about ... Idiots, explosives and falling anvils." -- Calvin and Hobbes, Bill Watterson Connection closed by foreign host. >
The component gets it's data from the command "fortune -a" - the normal unix command which dumps out a random fortune cookie - read via a ReadFileAdaptor, reading from the command pipe at a constant bit rate. The ReadFileAdaptor is wired up so that data is passed through to the FortuneCookieProtocol's "outbox" outbox.
At the end of the cookie, the FortuneCookieProtocol component terminates, closing the connection (it receives and passes on the producerFinished message generated by the ReadFileAdapter component).
FortuneCookieProtocol([debug]) -> new FortuneCookieProtocol component.
A protocol that spits out a random fortune cookie, then terminates.
Methods defined here
x.__init__(...) initializes x; see x.__class__.__doc__ for signature
Initialises component. Sets up a ReadFileAdapter to read the result of running 'fortune'.
All the interesting work has been done by linking the file reader's output to our output. Messages sent to control are unchecked and the first message causes the component to exit.
