[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz 05 Aug '21

05 Aug '21

hi there, folks: I'd really like to release 0.7.0 but I would like it to be at least a little bit tested before I do so. Could those of you with CVS trees check everything out and see if it performs as advertised? Deeper bugs than that will have to wait for the next release, but I'd at least like to know if it works for someone other than me. Thanks. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |_____| |_____ | | | | @ t w i s t e d m a t r i x . c o m http://www.twistedmatrix.com/~glyph/

[Twisted-Python] Get IP of connecting client in XMLRPC server

Hello, On 18 May 2004, the following message was posted to this mailinglist: Jp Calderone exarkun at divmod.com wrote: >Daniel Newton wrote: > > I have a simple XML-PRC server similar to the example below: > > from twisted.web import xmlrpc, server > > class Example(xmlrpc.XMLRPC): > """An example object to be published.""" > > def xmlrpc_add(self, a, b): > """Return sum of arguments.""" > return a + b def xmlrpc_whatIsMyAddress(self): return self.transport.getPeer().host > > if __name__ == '__main__': > from twisted.internet import reactor > r = Example() > reactor.listenTCP(7080, server.Site(r)) > reactor.run() > > I want to be able to get the address of the client that calls the xmlrpc > method can anyone help me with this? This solution didn't work because 'transport' isn't a property of the Example class. I'm currently in the process of changing from a customized SimpleXMLRPCServer to a twisted XMLRPC server solution and I need to insert the client IP into the attributes passed to the called xmlrpc method. Anyone who knows the answer and is willing to share the info? Regards, Remy

[Twisted-Python] An XMPP client with SSL support
by Pedro Sanchez 18 Sep '09

18 Sep '09

Hello, I have a sample XMPP client with the following structure: from twisted.words.protocols.jabber import client, jid from twisted.internet import reactor ... factory = client.basicClientFactory(myJid, myPasswd) reactor.connectTCP(host,5222,factory) reactor.run() It works well, I can connect to the XMPP server. But I would appreciate if some one could give me some hints on what's required to get the client to connect using a secure SSL link. Thanks, -- Pedro

[Twisted-Python] Twisted meetup/discussion at EuroPython?
by Terry Jones 30 Jun '09

30 Jun '09

I was thinking it would be nice to have a Twisted interest group meetup at EuroPython (June 30 - July 2) http://www.europython.eu Would people be interested in attending? Does someone more qualified want to organize it? Are any Twisted developers planning to be at EuroPython? The submissions page http://www.europython.eu/submission/ has a category for Interest Group Meeting or Discussion. I'm thinking more along the lines of the former - that it would be nice to be better connected to other Twisted programmers in Europe, to put a face to some of the names on the mailing list / IRC, etc. Terry

[Twisted-Python] Available for short-term Twisted consulting, e.g. training, design (but not coding)
by Itamar Shtull-Trauring 22 May '09

22 May '09

Need help with Twisted, distributed systems or or just plain old software architecture? Due to a repetitive strain injury I am unable to type much (though I am slowly improving), and so I'm taking time off of work to recover. As a result I am available for short-term consulting until I recover, e.g. training or design work, assuming of course it does not involve any typing. I've worked on Twisted itself, as well as projects ranging from high-performance distributed C++ servers, to an access control framework for an airline reservation system, to a multimedia kiosk system for the Israel Museum in Jerusalem: http://itamarst.org/resume.html Send me an e-mail if you're interested. -- Itamar Shtull-Trauring

[Twisted-Python] Twisted plugins and py2exe
by Gabriel Rossetti 10 May '09

Hello everyone! I used py2exe on a Twisted app of mine and I get this exception : Traceback (most recent call last): File "proj\service.pyc", line 1308, in connectionMade File "proj\service.pyc", line 1640, in _register File "proj\service.pyc", line 504, in loadPlugins File "twisted\plugin.pyc", line 200, in getPlugins --- <exception caught here> --- File "twisted\plugin.pyc", line 179, in getCache exceptions.AttributeError: ZipPath instance has no attribute 'setContent' Has anyone ever had this problem while using plugins with Twisted and py2exe? Thank you, Gabriel

Re: [Twisted-Python] cx_Oracle, Twisted - rollback failed
by Steve Lewis 03 May '09

03 May '09

> Is there some way it can determine that the connection has been lost aside > from trying the rollback (and is compatible with other DB-API 2.0 modules)? > > Jean-Paul Oops, I actually did see my message going through now. Sorry for the duplicate. To answer your question, I was under the impression that the cp_reconnect would check to see if the connection existed already. Is there a way to have it check that query before rolling back? I'm guessing other databases/apis don't throw exceptions on a rollback if the connection is gone? Steve

[Twisted-Python] subclassing and mixing protocol.ReconnectingClientFactory and pb.PBClientFactory
by Fabrizio Mancini 30 Apr '09

30 Apr '09

Hi, i've implemented a pb client by writing a class which inherits from object and a class which inherits from ReconnectingClientFactory and PBClientFactory. Till now it's all ok, the client detects the disconnection and try to reconnect with an exponential delay if the connection is not immediatly reestabilished. The calls to the callRemote("get_item") method are repetitive, but for sake of simplicity i've cut off the code that controls if there is already another call running. The problem: i'd like to manage something like the clientConnectionMade method when the client reconnect (thanks to the ReconnectingClientFactory) after a disconnection and launch again the MypbClient.connect() method as i do in the "if __name__ " statement, but i can't guess how to do it. This is the code i'm using. Thanks in advanche, any help appreciated, and hope to have been clear enough Fabrizio class MypbClient(object): def __init__(self): self.clientfactory = MypbClientFactory() self._scheduledCall] = task.LoopingCall(self.get_item) self._scheduledCall].start(10, False) def connect(self): reactor.connectTCP(server_ip, server_port, self.clientfactory) self.rootObj = self.clientfactory.getRootObject() self.rootObj.addCallback(self.initiateChain).addErrback(self._eb) def initiateChain(self, broker): self.broker = broker self.d = self.broker.callRemote("get_item") self.d.addCallback(self.got_item).addErrback(self._eb) def get_item(self, result): self.d = self.broker.callRemote("get_item") self.d.addCallback(self.got_item).addErrback(self._eb) def got_item(self, record): self.op = doSomethingWith(record) #returns a deferred class MypbClientFactory(pb.PBClientFactory, protocol.ReconnectingClientFactory): def __init__(self): pb.PBClientFactory.__init__(self) def clientConnectionMade(self, broker): self.resetDelay() pb.PBClientFactory.clientConnectionMade(self, broker) def clientConnectionFailed(self, connector, reason): pb.PBClientFactory.clientConnectionFailed(self, connector, reason) if self.continueTrying: self.connector = connector self.retry() def clientConnectionLost(self, connector, reason, reconnecting=1): pb.PBClientFactory.clientConnectionLost(self, connector, reason, reconnecting=reconnecting) protocol.ReconnectingClientFactory.clientConnectionLost(self, connector, reason) if __name__ == "__main__": dpc = MypbClient() dpc.connect() reactor.run()
