[Twisted-Python] How to run Twisted as a service in Windows?
by Mona Yazbeck 11 Aug '06

11 Aug '06

Hello, I am on Windows, and I have Python 2.4 I am starting twisted with twistd.py for my wiki, but it opens a command prompt so as soon as I log off the server it is no longer working and if I restart it is the same thing. How can I run it as a service so it will always be up? I don't know much about twisted I just installed it with the MSI and follow 2 or 3 instructions from MoinMoin website (the wiki). Thanks

[Twisted-Python] Multiple client handling...
by Grebekel 11 Aug '06

11 Aug '06

Greetings fellow writters of Twisted code. I've been looking for some answers about Twisted but Twisted's docs seem to be of a twisted nature. Perhaps I've been looking in the wrong places. I'd like my server to serve multiple clients, and to achieve this I'd need to know to which client deliver a specific message. -How does a Twisted server handle multiple client connections? -How can such a server deliver messages from a client to another (codewise)? -Any samples or tutorials online? Any help is much appreciated. grebekel

[Twisted-Python] Help implement protocol
by Keith Cheung (張國良) 10 Aug '06

10 Aug '06

Hi all, I want to implement some handshake protocol, say.. 1. Client: WhatDate 2. Server: 5Aug 3. Client: WhatYear 4. Server: 2006 5. Client: WhatTime 6. Server: 1005 So, for the client:- (pseudo code) def connectionMade(): send "WhatDate" state = askingForDate def lineReceived(data): switch state: askingForDate: date = data send "WhatYear" state = askingForYear break askingForYear: year = data send = "WhatTime" state = askingForTime break askingForTime: time = data state = initialState disconnect The switch case becomes gigantic as the protocol grow. Instead of keeping states, are there better ways to implement?

[Twisted-Python] UDP code samples ( to X3D )
by Sven-Erik Tiberg 10 Aug '06

10 Aug '06

Hi. I'm Sven Erik Tiberg newbee to this list, and working on a idea that's involves UDP transferes. Basically it contains of human interacting to a 3D world ( X3D ) with a simulink ( matworks ) model runing on a separate server. States will be bidirectionell transfered by UDP diagrams over Internet. I'v created some simulink modules that forces the model to run in pseudo-RT-mode and transfering states by UDP in format ( 10 times %f\t% ). And some X3D worlds that needs to be route'd to this UDP state tranferes by twisted-python scripts. Any hints and tips? Or as x-mas wish: code snipps. PS: Present reading "The Twisted Documantation" may 25 2006. Like the reactor concept. Sven-Erik Tiberg Dept of IT. Lulea Univ of Techn. Sweden

Thanks Andrew and Thomas.

Instead of keeping states, are there better ways to implement? Twisted code often uses dynamic method dispatch to methods with prefixed names like this: def connectionMade(self): self.sendLine('WhatDate') self.state = 'askingForDate' def lineReceived(self, line): handler = getattr(self, 'state_' + self.state) handler(line) def state_askingForDate(self, line): self.date = line self.sendLine('WhatYear') self.state = 'askingForYear' ... -Andrew. _______________________________________________ Twisted-Python mailing list Twisted-Python(a)twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python

[Twisted-Python] anyway to get data from a protocol instance?
by wang wei 09 Aug '06

09 Aug '06

please have a look of fellow code. from twisted.internet import reactor, protocol class echo(protocol.Protocol): def __init__(self): from Queue import Queue self.q = Queue() def lineReceived(self, line): self.q.put(line) class echofactory(protocol.ServerFactory): def buildProtocol(self, addr): p = echo() p.factory = self return p class runEcho: def __init__(self): a = echofactory() reactor.listenTCP(1024, a) reactor.run() My question is how can I get size of Queue q from another class when the program running.

[Twisted-Python] Writing a simple nameserver
by Yves Glodt 09 Aug '06

09 Aug '06

Hello, I have a database which contains a list of hosts with their IP-addresses, and I need to be able to connect to them by their name. The plan is to write a simple daemon using twisted names which accepts the dns query, looks up the requested address in the database, and answers the dns query. How would I do that with twisted names? p.s. (I skimmed over the documentation but got blinded by "Undocumented" labels.) Best regards, Yves

[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
