[Twisted-Python] subclassing twisted.web?
by Kendall Clark Feb. 12, 2002

Feb. 12, 2002

Hi, I'm playing around with some REST ideas[1], and I want to use this approach to build a web-forum-like[2] app for one of my busy content sites. I want to use a standalone, Python-based http server for this app, so I've been looking at the simple http servers in the Python lib, Zope's Z3, Medusa, and twisted.web. For various reasons[3], I'd like to try twisted.web first, but I have a few qestions -- (1) Is there a 'servlet' or other programming model to use with twisted.web? If so, is … [View More]

[Twisted-Python] Words.Participant capabilities
by Kevin Turner Feb. 12, 2002

Feb. 12, 2002

So, I was looking at doing /whois for words.ircservice, and found that lots of accessors weren't available, and there may be a bunch of questions as to whether they should be. One central question is "Do queries about a participant get answered by the server, or by the participant's client?" Having the server answer the questions is faster and cuts down on traffic, particularly if it's a question that everyone is frequently going to be asking about everyone else. But letting the client … [View More]

[Twisted-Python] International Python Conspiracy 10
by Glyph Lefkowitz Feb. 11, 2002

Feb. 11, 2002

Some members of the Twisted development team, including myself, attended IPC10 this last week. ( http://www.python10.com/ ) In general, the conference was a huge success. The talk that Moshe Zadka and I gave was heavily attended. Various materials related to the conference, including photos, the paper, and erratta are available at: http://twistedmatrix.com/users/glyph/ipc10 There will probably be a few more additions, since I've been really busy after getting back from the … [View More]conference. Also, most of the Twisted development team met in meatspace for the first time. If you were there, either at the paper presentation or at the Birds of a Feather session, thanks for dropping by! We got some good feedback from the people who attended both of these, and that was mainly that our key problem is (surprise) documentation. It was hard to decide what features of the conference to describe in detail here, since I had a lot of fun and met a lot of people, so I'll focus on what impact these things will have on the future development of Twisted itself. There was an incredible amount of interest in Twisted; I found that often, rather than trying to generate interest, I was having to keep people's expectations low. The chief reason was that Twisted doesn't have very good documentation, and so it's difficult for end-users to get into it. I had underestimated how useful something like Twisted could be to the average web developer. Currently I'm trying to develop a documentation strategy, and I'm still not sure what form it will take. If you are interested in writing documentation, but don't understand Twisted well enough to do so, please contact me and let me know what information you need to get started. The file doc/index.html in the distribution is an outline of the docs we need -- there is nobody signed up to work on them yet. A few people have mentioned their interest, and if we're lucky, enough time will clear up in all of our schedules to permit working on that. While Developer Day was going on, the Twisted team met outside the conference to talk about the Version 1.0 release strategy. I'd like to get to 1.0 by about april, since I think we've already got a lot of functionality, and one of the things that's making it difficult to document is that it changes all the time. It is easiest to define release criterea when your test suites are written by someone else. We hope to leverage that by using use-cases derived from other sorts of server software for those parts of Twisted which are not really integrated: we can tell when twisted.mail is at the postfix/qmail level of mail application, when twisted.web can compete with apache, and when twisted.names can replace BIND. Those are all going to be release criterea, but we also need some way to decide when our integration between services is good enough. Since including them in this email was making it rediculously long, I've put up a webpage that is a first draft at figuring out what we need for 1.0: http://twistedmatrix.com/users/glyph/twisted/one-point-oh.html Twisted Developers (especially those not at IPC10), your comments are appreciated. Hope to see you all there next year! -- "Cannot stand to be one of many -- I'm not what they are." -Guster, "Rocketship" glyph lefkowitz; ninjaneer, freelance demiurge glyph @ [ninjaneering|twistedmatrix].com [View Less]

[Twisted-Python] Documentation
by Shandy Brown Feb. 8, 2002

Feb. 8, 2002

Hi. Glyph invited me to share my thoughts about the state of Twisted Documentation, and why I chose not to use Twisted in my project, Metagame-Sector ( http://sjbrown.geeky.net/metagame-sector/ ). I guess the best way to explain why I didn't choose Twisted is to look at what I did choose, SimpleXMLRPCServer ( http://www.python.org/doc/current/lib/simple-xmlrpc-servers.html ). My project and my attitudes are such that I don't want to spend a lot of time on client-server implementation. I … [View More]

[Twisted-Python] IM: Design ideas
by Travis B. Hartwell Feb. 6, 2002

Feb. 6, 2002

Hey all, I hope y'all at IPC10 are having enough fun for the lot of us. Also, I hope y'all don't get annoyed with my constant feature requests and ideas and no code (as of yet). I hope to change that. But, in the meantime, I'm going to continue to throw out my ideas. Please tear it apart, kill it, praise it, or whatever you wish! As many of you know, I'm primarily a text-mode (console/xterm/ssh) and screen kind of guy, though I do live in X when I'm at home. (Gotta love the … [View More]

Glyph has set up a CafePress storefront -- now you too can be proudly emblazoned with the Twisted Logo! http://www.cafepress.com/twistedlabs Jason (I went ahead and paid the outrageous 2nd day air shipping to make sure my shirt arrives before IPC 10...)

[Twisted-Python] Call Profiler - profile your Zope website
by Itamar Shtull-Trauring Feb. 2, 2002

Feb. 2, 2002

This sounds like a useful functionality for us: <http://www.zope.org/Members/richard/CallProfiler/> This is infrastructure for profiling specific requests, as opposed to the whole server, so it's much more useful for figuring out why your PB or web request is slow.

[Twisted-Python] RFC: Dropping support for Python versions prior to 2.1
by Itamar Shtull-Trauring Feb. 2, 2002

Feb. 2, 2002

Hi, We've been discussing dropping support in Twisted for versions of Python prior to 2.1. There will be a number of limitation for people developing Twisted itself, though not, of course for people *using* Twisted - the coding standard will probably disallow list comprehensions, print>>, and import X as Y. On the plus side, 2.1 will allow use of new features such as weak references, string object methods and so on. Additionaly, pyOpenSSL does not run on Python 1.5.2. On the other … [View More]

[Twisted-Python] IM feature requests
by Travis B. Hartwell Feb. 1, 2002

Feb. 1, 2002

Hey all, I am excited for the new GTK IM client that is in CVS. I've been happy with its features thus far -- pretty good for a program that is so new. Anyway, since I am in some strange e-mail writing mood, I thought I would document for the world (or at least those planning on working on GTK IM in the near future) some of my feature requests for t-im, so that it becomes very useful for me. These aren't all high priority, and I myself might want to try to add some of these. … [View More]
