[Twisted-Python] can pb.Copyable objects be compared for equality after a round trip?
by Robert Gravina June 28, 2006

June 28, 2006

Twisted-list, In an application I'm writing I would like all Perspective Broker clients to share some list of objects and have them all keep in sync when one of the clients updates an object's attributes (imagine say a shared address book - I'm not creating an address book, but it's easier than explaining the details of my app). I've created a pb.Cacheable class for the purposes of notifying clients when new objects are added to this list which works fine (I based this on the … [View More]

[Twisted-Python] Creating a proxy between a flash client and xmlBlaster
by Richard Strong June 28, 2006

June 28, 2006

Hi all, I am attempting to build a proxy between xmlBlaster and a Flash client using an XmlSocket on the client side. My cludge was going to be the twisted library. Essentially I want to have the update function of xmlBlaster call basic.LineReceiver.sendLine(...) and the lineReceived function of twisted to call self.msgPublish. I have a through line working from the Flash client to xmlBlaster, but cannot get a message from xmlBlaster to Flash (even after a Flash client has successfully … [View More]logged in.). Any help would be divine. Here is a copy of the source code for the server that has been created: from const import * import sys import os import time import signal import threading sys.path.insert(0, CLIENTPATH) import bistBlast from twisted.protocols import basic from twisted.internet import reactor, protocol from twisted.internet.protocol import Protocol class Proxy(bistBlast.bistBlast,basic.LineReceiver, threading.Thread): delimiter = '\0' def __init__(self): print "init======================================================>" #bistBlast.bistBlast.__init__(self, 8009) def update(self, sessionId, key, content, qos): print """__recieved message__ """ print "__key__", key print "__content__\n", content.data print "__qos__", qos #print "" self.sendLine('<MESSAGE USER="John" TEXT="Hello, my name is John!" />') #self.message('<MESSAGE USER="John" TEXT="Hello, my name is John!" />') #self.sendLine(key) return "" def lineReceived(self,line): if line == "<policy-file-request/>": print "\t sending policy file" self.sendLine("<?xml version=\"1.0\"?><cross-domain-policy><allow-access-from domain=\"*\" to-ports=\"8007\" /></cross-domain-policy>") #bistBlast.bistBlast.__init__(self, 8009) #self.msgSubscribe("test") else: print "LINE RECEIVED" try: bistBlast.bistBlast.__init__(self, 8009) self.msgSubscribe("test") except: print "already connected" self.msgPublish("<key oid='test' />", "<what />") self.sendLine('<MESSAGE USER="John" TEXT="Hello, my name is John!" />') def sendLine(self, msg): print "Sending Message" basic.LineReceiver.sendLine(self, msg) print "Sent Message" def message(self, msg): self.transport.write(msg + '\n' + delimiter) print msg + '\n' # Main if __name__ == '__main__': ProxyFactory = protocol.ServerFactory() ProxyFactory.protocol = Proxy reactor.listenTCP(8007, ProxyFactory) reactor.run() [View Less]

Hi, I have been follow twisted for like half a year now, I have read the doc and the oreilly book, but i still cann't do some simple work in the twisted way. Could someone give me a hint?

[Twisted-Python] Mobile code using PB
by Tzahi Fadida June 28, 2006

June 28, 2006

Hi, I am looking for a way to have a mobile code feature using PB very similar to pyro. The idea is like this: There is a server and a client. The client trust the server completly. The server does not trust the client. The client gets arbitrary classes from the server and if a module of the class is missing it raises an exception that will ultimately result in downloading the module and injecting it. If the module exists locally (same ver or something like that) do not download it. Basically … [View More]

[Twisted-Python] reset/restart reactor problem
by Joseph Newman June 27, 2006

June 27, 2006

Hi All, I am porting an academic middleware project, currently implemented in C++ and Java, to python. It extensively uses multicast for communicating general events and TCP to communicate with a database. The multicast messages that I send out depend on the results that I first obtain from the database. I would prefer to serialise each of these requests in turn, but its not immediately obvious to me what the best way to do this using Twisted is. If I could reset the reactor after … [View More]

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello there, I'm attempting to think about possibly organizing a Twisted sprint (focus on closing bugs) in the San Francisco/Bay Area for mid to late July.

There are also some people in town for the summer for various reasons who've expressed interest. So this is an open … [View More]
