We have been asked to develop and application for a client that is a 'notification" system. We would like to use python, but are struggling to find the right starting point. Any suggestions, tips or sample code would be appreciated.
Application outline; Machine A is running a "listener" application that is connected to a another device via the serial post and waits for events. We have not problem working with the serial port, or the waiting for the event to happen. When A received a specific event, it needs to send a message to machine B that and event has occurred and that type of event. Machine B will take the event notification, processes some additional information (ie. database lookups) and then notify a series of clients that have "registered" with machine B to receive events. I think this is sometimes called "published/subscriber" ??? We have looked at xmlrpc, but at there would be no outside clients, it seems to have a little more overhead than we need. We also looked at the asyncore and asynchat, but are having difficulty gettng starting with these. If someone has a working example of a "chat" server using these modules they could share it would be very helpful. So ... any suggestions ? -- http://mail.python.org/mailman/listinfo/python-list
