[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

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: spawnProcess() never ending when installSignalHandlers=False
by Matt Feifarek 03 Feb '07

03 Feb '07

Hello. I'm using Twisted 1.3.0 on python2.4 on an Ubuntu-Hoary x86 Linux box. I'm using twisted and spawnProcess() with a Queue structure to chain processes that need to be called (specifically, imagemagick commands). I use the "processEnded" event/method of t.i.p.ProcessProtocol to go from one task to the next. Twisted shares a python process with a multi-threaded web-app-kit (Webware) so it has to be run in a thread. This worked well on other older versions of twisted and older versions of python; also on linux. I've tracked down the problem to be twisted itself (or my incorrect use of it) rather than my code. This example illustrates it: ------------------------------------------------- from twisted.internet import reactor from twisted.internet.protocol import ProcessProtocol class MyProt( ProcessProtocol ): def processEnded(self, reason): print "ended.", reason executable = '/bin/touch' args = ( '/tmp/foo.txt', ) args = (executable,) + tuple(args) reactor.spawnProcess( MyProt(), executable, args ) reactor.callLater( 5, reactor.stop ) #reactor.run() reactor.run(installSignalHandlers=False) ------------------------------------------------- As is, this code never runs the "processEnded()" method of MyProt(). If I change the reactor.run() parameter to leave the signal handlers on, it works. Note that I need to leave the signal handlers turned off because I can't run the reactor in the main thread; Webware needs that. I also know that the subprocess is giving up its file descriptors; I can see that if I put more print statements into MyProt(). And I know that the subprocess is working; /tmp/foo.txt is there. It seems that somehow the reactor is using signals to notice when a process has ended; this makes a certain ammount of sense intuitively, though I don't understand the nitty-gritty of processes and signals at all. And more importantly, this has worked before on other combinations of twisted/python. Is this a bug? If so, has it been fixed? If not, what should I do to detect when a spawned process is finished? Thanks very much. Twisted rocks.

[Twisted-Python] Process completion not detected on HP-UX (#608)
by Glenn Hochberg 08 Aug '06

08 Aug '06

I ran into a problem on HP-UX (B.11.23 U ia64) using Python 2.4.3, whereby processes started via reactor.spawnProcess() never seem to get the completion event. I fished around via Google and found that this is ticket #608, which has been hanging around for over 2 years. I'd be willing to help troubleshoot this if someone could provide some guidance. I'd really like to get this fixed ASAP, so any help is appreciated. Thanks. Please reply to me directly in addition to the list, as I'm not subscribed. -Glenn Hochberg

[Twisted-Python] XMLRPC and timeout...
by Chaz. 31 Jul '06

31 Jul '06

I am not sure my original message made it to the list, so I thought I would reissue it. If you have seen it before, I am sorry for issuing it again. I have an XMLRPC server and client. I am trying to build both of them defensively - in other words I would like to cancel the client request should a time period be exceeded. I would also like to give the server a specific time to answer. Can anyone give me an idea how to do them? Peace, and thanks in advance, Chaz.

[Twisted-Python] twisted web question
by Alex Greif 31 Jul '06

31 Jul '06

Hi NG, I am completely new to twisted, but want to give it a try :) I have a small website running, serving dynamic content with Pylons. For switching to twisted, do I have to use the web or the web2 module? thanks, Alex.

[Twisted-Python] Basic twisted question
by Torsten Irländer 29 Jul '06

29 Jul '06

Hi, I'm new to twisted and I have some problems on understandins some basic concepts on building applications upon the twisted framework. The examples in Fettig's book brought me on the right track I think but I'm not sure. So I would like to ask you for some hints and advices. I try to build a small IMAP client which shoul be able so do some very basic operations lke mailboxlisting and fetch some images. Nothing more for the first. Based on Fettig's IMAP examples I did the following: For each operation I want to do I wrote a own protocol. I started with a basic protocol which simply connects to the server. Then in the next step I wrote the protocol which lists the users mailbox. This protocol is inheritated from the first exentend this with the methods to list the mailbox. As you can see I planned to build some kind of inhertance tree for the protcols. Continuing this way I would end up with many small protocols doing one single task, and I'm not sure If this is a good approach. Do you have any comments on this? If it is not clear to you what I meant I can provide some code of course. At the moment this things is pretty small :) best regards Torsten
