[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] Reconnecting PB Client
by Don Smith 12 Sep '07

Does anyone have some example code for building a reconnecting PB client? This is what I have now: from twisted.spread import pb from twisted.internet import reactor from twisted.python import util events = pb.PBClientFactory() reactor.connectTCP("localhost", 8789, events) queue = events.getRootObject()

[Twisted-Python] problem running ldaptor-webui
by Michael Torrie 16 Mar '07

16 Mar '07

I am using python 2.4 on FC6, and Twisted 2.5.0. I have installed the latest stable versions from source of Nevow, Webut, and ldaptor (0.0.43). I tried to run the ldaptor-webui program, but encountered the following traceback: Traceback (most recent call last): File "/usr/bin/ldaptor-webui", line 4, in ? from ldaptor.apps.webui import main File "/usr/lib/python2.4/site-packages/ldaptor/apps/webui/main.py", line 5, in ? from ldaptor.config import LDAPConfig File "/usr/lib/python2.4/site-packages/ldaptor/config.py", line 4, in ? from ldaptor import interfaces File "/usr/lib/python2.4/site-packages/ldaptor/interfaces.py", line 3, in ? class ILDAPEntry(components.Interface): AttributeError: 'module' object has no attribute 'Interface' Apparently this stems from something related to Zope. The imported module in question, <module 'twisted.python.components' from '/usr/lib/python2.4/site-packages/twisted/python/components.pyc'>, indeed has no attribute Interface. However it does import "interface", module <module 'zope.interface.interface' from '/usr/lib/python2.4/site-packages/zope/interface/interface.pyc'>. Is ldaptor-webui in need of updating to run with something new that either Twisted or Zope changed? thanks. Michael

[Twisted-Python] Making a duck-typed traceback from a Failure
by Jonathan Lange 28 Feb '07

28 Feb '07

Hello, I've recently been doing work with Twisted tests from within the Zope testrunner. It's a real pain because if the tests or their callbacks raise exceptions, no traceback gets given to the result object. See #2495. The fix I've uploaded doesn't actually help me. By the time the result object gets the failures, they've been cleaned with cleanFailure -- Failure.tb is None and everything is a string. Is it possible to make a duck-typed traceback from a cleaned Failure? I haven't really looked into it, but I can't think of why not off the top of my head. Granted I ran out of thought gluons a couple of hours ago. cheers, jml

[Twisted-Python] specifying the site and port to a twisted web server
by Dennis Allison 28 Feb '07

28 Feb '07

I have written a highly simplified twisted web server using twisted extending one of the demos, but I have one small problem. I cannot see out how to arrange to have the server listen one particluar address:port combination. The system I want to use it on has a pair of NICs and I need the server to listen on one NIC and not the other due to port conflicts. Any help would be appreciated.

[Twisted-Python] using py2exe or pyinstaller on twistd
by Alvin Wang 27 Feb '07

27 Feb '07

I mentioned at Pycon that I wanted to use Py2exe to distribute my tac. How would it be done? The alternate method I had been using was not using a tac file but that was not recommended. Thanks Alvin Wang PS It was great meeting some of the Twisted folk at Pycon. Highly recommended!!

[Twisted-Python] twisted-names: Cryptic error with no traceback?
by Paul Marks 27 Feb '07

27 Feb '07

Some users of a program that I'm writing have been reporting this error that I so far have been unable to track down. It seems that it originates from Twisted, but that it skips around my errback handler, and provides no traceback information: Traceback (most recent call last): Failure: twisted.names.error.DNSQueryTimeoutError: My query is made from line 121 here: http://dtella.svn.sourceforge.net/viewvc/dtella/tags/1.0.2/dtella_dnslookup… Does anyone have any insight as to where this error could be coming from, and why it isn't getting trapped by my errback function? I don't know yet whether this is a problem in Twisted, or if I'm doing something incorrect in my err_cb.

[Twisted-Python] LineReceiver
by Lee Connell 26 Feb '07

26 Feb '07

Hello all, I am building a basic chat program. I am using LineReceiver for the protocol on both the server and the client. My problem is when i loop through all the clients in my ServerFactory and choose to send data to the client with multiple calls to transport.write(data), the client side does not pick it up in two seperate calls, instead it is received in one lineReceive. In the server I call transport.write() twice, the client however receives both calls in one lineReceive instead of two lineRecieve calls, how can I get lineReceive to be fired for each transported message? //// CLIENT LINE RECEIVE //// def lineReceived(self, line): if self.app: self.app.addMessage(line) //// SERVER CONNECTION MADE //// def connectionMade(self): self.factory.clients.append(self) host = self.transport.getPeer().host + ": joined the server." for c in self.factory.clients: c.transport.write(host + '\n') if self == c: c.transport.write(self.getMOTD()) ### getMOTD just returns some string ###
