[Twisted-Python] Python a post-Object Oriented Language?
by John Benson Nov. 19, 2003

Nov. 19, 2003

Hi, I saw the above characterization in one of the itamarst.org twisted presentation slides. Although I'm just a journeyman programmer and somewhat unaccustomed to the rarefied atmosphere of many twisted Python discussions, I'm curious to hear why Python would be "post-OOP". If I recall correctly, my little O'Reilly C++ book said that OOP meant you had 4 things (abstraction, encapsulation, hierarchy and something else that escapes me at the moment, maybe "coolness"). I also recall that … [View More]

[Twisted-Python] Forum vs. mailing list
by Hegedus, Matthew S Nov. 19, 2003

Nov. 19, 2003

Philippe Lafoucrière mentions his favoring of a forum over a mailing list. A forum sounds much better to me. Topics can be nicely separated, past knowledge can be easily searched, and email inboxes can be freed from much clutter (or at least make room for spam). Is it not too late to implement a forum?

[Twisted-Python] Retrieving Woven html element IDs
by Justin Johnson Nov. 19, 2003

Nov. 19, 2003

In woven, html elements are automatically given an id (eg. <div id="woven_id_18612312">... where the number is id(self) for the view). I have a div tag I'm trying to using to dump error logs into on the fly with LivePage and display them to the user. It seems that I cannot reference a tag by name with javascript, so I need access to the auto-generated id. If I had the id I could do something similar to the example below. Does anyone know if it's possible to lookup this id in woven? … [View More]

[Twisted-Python] win32eventreactor bug?
by Justin Johnson Nov. 18, 2003

Nov. 18, 2003

I was running twistd on windows, serving out a custom tap which is just a web app and a pb service. As it was doing it's thing, suddenly a ton of output started dumping on the log. Did I find a bug in the win32 event reactor, or am I hitting some sort of limit? I can send some code along if necessary, but nothing in the log looks specific to my code.

[Twisted-Python] SOAP client for Twisted
by Dave Kuhlman Nov. 18, 2003

Nov. 18, 2003

I've added minimal SOAP client support to Twisted. I did it by copying a bit of code from twisted/web/xmlrpc.py and by using some of the functionality from SOAPpy and adding it to twisted/web/soap.py. I've tested it lightly and it seems to work. Is this of interest to the Twisted project? If so, let me know and I'll send it along. Someone who knows Twisted better than I will have to look at the code to make sure that, given the way I implemented it, it does not block. Dave -- Dave … [View More]

[Twisted-Python] new ftp implementation
by Jonathan Simms Nov. 18, 2003

Nov. 18, 2003

Hello all, Just wanted to announce there is a new version of the ftp server/protocol. the new protocol: - Supports cred, so you can control/abstract the filesystem - includes an anonymous-only avatar/realm - supports pipelining of commands - intentionally does not support globbing (to help prevent security holes) - connection limiting (ex. max 100 users) - individual timeouts for protocol interpreter idle time and dtp connection times todos: - the permissions-… [View More]

[Twisted-Python] UNIXServer and its socket
by Matteo Giacomazzi Nov. 18, 2003

Nov. 18, 2003

In my application I have a server that listens on a UNIX socket. When I kill the application, the socket file remains in the filesystem so when I restart it I always achieve an "Address already in use" error. Should I delete it manually any time I stop the application or is there a more elegant way to solve this problem? The application is a plugin for twistd. Thank you in advance. Matteo

[Twisted-Python] Browser oddities and Woven...
by Stuart Hungerford Nov. 18, 2003

Nov. 18, 2003

Hi all, I probably shouldn't be too surprised, but I'm experiencing some odd behaviour with IE 6.0 .vs. Mozilla 1.5, both on Windows XP. I've developed a Woven application that generates three HTML pages, let's call them A, B, and C. A's render() method does a redirect to B. B's view methods generate an XHTML meta tag with the content attribute set to a refresh and new URL for C: <meta content="10;http://example.org/C" http-equiv="refresh" /> With Mozilla as the client … [View More]

[Twisted-Python] another probably very simple question
by Phil Christensen Nov. 17, 2003

Nov. 17, 2003

this is actually the first time i've ever written a PB client in python. since my java client was calling the remote methods out of the awt/swing event thread, i never had to deal with this particular issue. while i'm waiting for the update to the java pb packages (*cough*itamar*cough* ;-) ), i figured it would be worthwhile to do up a text-based client in python. i know this relates to my poor understanding of deferreds, but i just can't figure out exactly how to go about doing what i want to … [View More]
