[Twisted-Python] Twisted and unladen swallow
by György Vilmos July 11, 2009

July 11, 2009

Hi All, I use twisted as a flexible (authoritative) DNS server, and apart from its speed, I'm completely pleased with it. As you may know, Google has started a project -named unladen swallow- to improve python's performance, so I've taken a quick look at it, compiling the latest version (from svn trunk, which is based on python 2.6.1) on FreeBSD and compared the numbers with plain python's (2.6.2) performance. As this is a DNS server, the performance indicator is queries per second. The … [View More]

[Twisted-Python] Perspective broker and SSL
by Sean Hollingsworth July 9, 2009

July 9, 2009

I'm trying to add SSL support to an app that makes use of Perspective Broker. In my server I have the following: ccf = ssl.ContextFactory() ccf.method = SSL.TLSv1_METHOD reactor.listenSSL(PORT, pb.PBServerFactory(RLFactory()), ccf) and in my client I have this: ccf = ssl.ClientContextFactory() ccf.method = SSL.TLSv1_METHOD reactor.connectSSL(server, MY_PORT, factory, ccf) factory.getRootObject().addCallbacks(self._connected, self._connectFail) When the client connects to the server, I get … [View More]

[Twisted-Python] sudo asking for a password during utils.getProcessOutputAndValue()
by Steve Freitas July 9, 2009

July 9, 2009

Hi all, If from inside my twisted program I do... commands.getstatusoutput('sudo blah blah') ...it works great. If instead I do... utils.getProcessOutputAndValue('/usr/bin/sudo', path='/usr/bin', args=('blah blah',)) ...it gets stuck asking for the sudo password. I've tried a bunch of variations in the latter call, like lumping the args into the executable string, getting rid of "/usr/bin" in the executable, changing the path to the executing user's home directory and so on. Any ideas? Thanks! Steve

[Twisted-Python] imap and noop
by Darren Syzling July 8, 2009

July 8, 2009

I'm new to twisted and was experimenting trying to create an imap server based on the example within Twisted Network Programming Essentials. My test client is Thunderbird. I'm wondering if anyone has had any experience handling the 'noop' command here's my scenario: - I have two unread messages in a folder, I open thunderbird, select this folder and then select trash - trash has no messages. - Each folder is selected and fetched with a uid:* - My server correctly responds. - Each time I … [View More]

[Twisted-Python] Connecting to multiple servers
by Antonio Beamud Montero July 8, 2009

July 8, 2009

Hi all: What's the smart way to close the reactor and exit in an app like that: ------------------------- from twisted.internet import reactor from twisted.web.client import getPage def gotPageCallback(page): print "got a page!" getPage('http://www.google.com').addCallback(gotPageCallback) getPage('http://www.yahoo.com').addCallback(gotPageCallback) reactor.run() -------------------------- For example with a global counter and when reach to 2, then reactor.stop()? If I use reactor.… [View More]

Re: [Twisted-Python] Conch, getting the avatarId, session number, and terminal protocol instance of all connected users.
by asset July 8, 2009

July 8, 2009

I got just what I needed with a custom TerminalRealm sending the avatarId and TerminalUser to a custom TerminalSession, grabbing client host, port, sessionno and terminal at openShell(); then put in some cleanup on closed(). Thanks for pointing me right where I needed to go! ------------------------------ On Sat, 4 Jul 2009 02:11:36 -0700, asset wrote: >Ive been at it for several days now trying to get at the username >(avatarId), session id (SSHChannel session # I imagine), and … [View More]

[Twisted-Python] untwisting twistd
by Jared Gisin July 8, 2009

July 8, 2009

I am currently working on writing an application using the twisted framework. The problem that I have is that I do not want to use twistd. In fact, I find twistd to be inappropriate as it defaults pidfile and logfile to something specific to twisted, not my application, and it seem completely silly to have to pass in -pidfile and -logfile params when stating it up. Those parameters should be specified as part of the Application object itself, and should allow for CLI override. Further, as I … [View More]

Kind regards Tax #!/usr/bin/python # # Run this as root with the command # twistd -y dnsfilter.py from twisted.internet import app, defer from twisted.protocols import dns from twisted.names import … [View More]

[Twisted-Python] XML-RPC over Unix Sockets?
by Kristian Larsson July 6, 2009

July 6, 2009

Hello! I'm trying to build a client / server setup using XML-RPC run over UNIX sockets. Putting together the server part was a breeze, just define an xmlrpc class and have the reactor use it with a listenUNIX() call. Now, since I've been unable to put together a client I don't really know that the server works, but I'm assuming it is. At least it does not generate any run-time errors. Now, on the client on the other hand I've basically copied this example: http://twistedmatrix.com/projects/… [View More]
