RE: remote routing questions

Hi Jos,

Unfortunately such off-host route sources don't work right now (that is, no one has implemented them yet! :), and JavaScript security doesn't allow a single JavaScript app to use servers in more than one domain.

Instead you'll need to write a tiny "repeater" written in a language other than JavaScript to subscribe to the source topic on mod-pubsub.org and publish to a mirror on your local server.

Perhaps something like the mini-app below, which we wrote using the Python PubSub Client Library.  I'll check this into mod_pubsub/python_pubsub/apps/repeater.py for those on the developer list who just want to do a cvs update.

import pubsublib, scheduler, asyncore

class StatusMonitor:
    def onStatus(self, event):
        #print "STATUS: " + str(event["status"])
        pass

class Repeater(StatusMonitor):
    def __init__(self, client):
        self.client = client
    def onMessage(self, event):
        #print "Message: " + event["kn_payload"]
        self.client.publish("/what/apps/blogchatter/pings",
                            event,
                            StatusMonitor())

ua = pubsublib.HTTPUserAgent()
client1 = pubsublib.SimpleClient(ua, "http://www.mod-pubsub.org:9000/kn")
client2 = pubsublib.SimpleClient(ua, "http://127.0.0.1:8000/kn")
client1.subscribe("/what/apps/blogchatter/pings",
                  Repeater(client2),
                  { "do_max_n": "10" },
                  StatusMonitor())
while 1:
    asyncore.poll(scheduler.timeout())
    scheduler.run()

Subject: remote routing questions


Hey all. I'm doing some experimentation now with the javascript pubsub lib. I've gotten it to work fine and dandy on a box with a local copy of the python server running. 

What i've been trying to do is create a route between the blogchatter topic on mod-pubsub.org (http://www.mod-pubsub.org/kn/what/apps/blogchatter/pings) and my local connection (say, /who/jos/s/24/kn_journal). 

the code i am currently using is like so:

kn.subscribe("http://www.mod-pubsub.org/kn/what/apps/blogchatter/pings", onMessage, {do_max_n:10}, {onSuccess:renderDisplay}));

I know the onMessage and renderDisplay functions work, as i use them to display the /what/chat topic. 

Any suggestions?

jos

ps. i just realized that my local box is on a local 10.0.0.x network - this might be the problem...
