[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] 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

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

[Twisted-Python] _Win32Waker
by Aron Bierbaum 21 Apr '09

21 Apr '09

I have been using a custom Qt4 reactor that derives from PosixReactorBase. As a result it creates a _Win32Waker to allow threads and signals to wake up the IO thread. It seems though that the current implementation only works about half of the time. The other half it exists with : File "...\Lib\python2.6\site-packages\twisted\internet\posixbase.py", line 170, in __init__ ReactorBase.__init__(self) File "...\Lib\python2.6\site-packages\twisted\internet\base.py", line 424, in __init__ self._initThreads() File "...\Lib\python2.6\site-packages\twisted\internet\base.py", line 813, in _initThreads self.installWaker() File "...\Lib\python2.6\site-packages\twisted\internet\posixbase.py", line 206, in installWaker self.waker = _Waker(self) File "...\Lib\python2.6\site-packages\twisted\internet\posixbase.py", line 77, in __init__ client.connect(server.getsockname()) File "<string>", line 1, in connect socket.error: [Errno 10049] The requested address is not valid in its context I have attached a simple test that shows that the following code does not always return "127.0.0.1", but sometimes returns "0.0.0.0" as the IP address. # Following select_trigger (from asyncore)'s example; server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) client.setsockopt(socket.IPPROTO_TCP, 1, 1) server.bind(('127.0.0.1', 0)) server.listen(1) client.connect(server.getsockname()) My current workaround just calls the following instead: client.connect(('127.0.0.1', server.getsockname()[1])) Any ideas on what is really causing the error? If there is not a better solution can this be added to trunk for future releases? Thanks, Aron

[Twisted-Python] New user - plugin question
by tim wylie 06 Apr '09

06 Apr '09

Hello, I'm a long time linux/python user who's just now starting to use twisted. I am looking for advice more than anything specific. We're working on a small game/etc server that has several small games that can be played between users. Maybe a card game, tic-tac-toe, etc. There are a lot of different plugin subclasses to inherit from-how do you know which is best? And with this kind of framework, is it better to have one interface class, say iGame, that all the games inherit from, or is it better to treat each game like a seperate plugin inheriting from different twisted plugin classes? There is a lot of good twisted documentation, but that is what also makes it difficult because each one does things differently depending on what they're implementing and it makes it difficult to decide which is the correct approach for what I want to do. So, if there are any good documents related closer to what I'm doing I'd appreciate the heads up on that as well. Well, thanks for your time.

[Twisted-Python] official packaging
by Esteve Fernandez 02 Apr '09

02 Apr '09

Hi all, I recently came across this issue [1], and Glyph commented about official packaging. We're using Ubuntu Hardy and created packages for Twisted 8.2.0, as Ubuntu LTS is our platform of choice. Those packages were accepted by their official maintainer (Matthias Klose, doko(a)debian.org) and uploaded to Ubuntu Jaunty and Debian unstable. Sadly, the official packages now use python-central (>=0.6.11), which isn't available in Hardy, so we'll have to stick to the packages in our PPA [2] In any case, we'll update them when Twisted 9.0 is released, but I think it would be better to upload them to a PPA repository officially approved by the Twisted team. Anyway, it would be great to have recent packages of Twisted for distributions that offer some kind of long term support contracts (Ubuntu, RHEL, etc.), but that tend to get a bit outdated. Cheers. 1 - http://twistedmatrix.com/trac/ticket/3102 2 - https://launchpad.net/~fluidinfo/+archive/ppa
