Greetings all. This may be a very basic question. I'm hoping to implement a postfix policy check client in twisted. It's a simple protocol. You send newline separated key value pairs like:
recipient=em...@ddr.ess sender=anot...@ddr.ess size=1024 helo_name=mail.server etc.. you terminate the request with an additional newline. The response comes back like action=OK You can send mutliple requests in the same connection. What I'm envisaging is a module that can be used to provide a deferred request/response pairing to my calling application. The module class will manage the single connection to the postfix policy daemon (I'm actually going to have persistent connections to a few daemons), and reconnect when necessary etc. Any requests will return a deferred that I can add callbacks to. How would you design this with twisted? I can easily envisage a way of using a clientfactory to instantiate separate connections for each request/response, but actually being able to simply send a request and receive the single response for that request is something I'm struggling to do within a LineReceiver instance (for instance). Would the twisted.protocols.amp module help given that I can't change the server-side protocol? Any advice much appreciated! Thanks.
