[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz Aug. 5, 2021

Aug. 5, 2021

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. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |… [View More]

[Twisted-Python] PB for Java status report
by Itamar Shtull-Trauring Jan. 6, 2002

Jan. 6, 2002

It's now possible to create Referenceables in Java - meanwhile simple remote_xxx style ones only, no support for Perspectives or Viewables yet. In other words, you can now create PB services in Java as well - I think it's pluggable enough that you could integrate this with any Java server architecture that uses streams (which is probably all of them :).

[Twisted-Python] FAQ-o-matic
by Michael Dartt Dec. 3, 2001

Dec. 3, 2001

I'd like to suggest the addition of a FAQ-o-matic (http://faqomatic.sourceforge.net/fom-serve/cache/427.html)to the Twisted site. I think it would make it much easier to get and to post info, as you wouldn't have to wait for someone to write The Definitive Documentation(tm) for a given subject. From what I've seen/experienced, the "document-as-you-go" approach works much better for open-source projects. I'm willing to do the work of getting the F-o-m set up. (Perhaps I should stick … [View More]

[Twisted-Python] Twisted 0.12.2
by Chris Armstrong Nov. 30, 2001

Nov. 30, 2001

Hey all. I released Twisted 0.12.2 today, it was mainly a bunch of bug fixes with a few features. Here's the changes: What's new in 0.12.2? Removed some broken and/or experimental code. Added poll() based event loop implementation. New minimal documentation for WebWidgets and Manhole in the doc/ directory. Made some changes to the listen API -- changed from listenOn to listenTCP, listenUDP, and listenSSL. Some UI changes for InstanceMessenger. Some caching support for … [View More]

Every other alternative (poll, kqeue, windows event thing) works by registering and unregistering objects - correct me if I'm wrong. So instead of having to emulate a select()-like API, we … [View More]

[Twisted-Python] Intro and "Slash- or Squishdot-style stuff?"
by Michael Dartt Nov. 28, 2001

Nov. 28, 2001

Hello, everyone. <introduction>I did some work with God--er, Glyph--on Twisted Reality back in the days when it was in Java. I've done a decent chunk of coding, including using Python (which is still my favorite language), but I admit to being almost a complete newbie when it comes to network programming. Other than that...I live in Madison, WI and work at EDS on the WI Medicaid account.</introduction> I'm considering using Twisted for a news/portal site in a similar style … [View More]

[Twisted-Python] cursors
by Kevin Turner Nov. 24, 2001

Someone, either Glyph or Tommi, mentioned that they wanted cursors a while back. "What's that," I asked; then thought "hm. I could do that." But I didn't. Only, now I did.

[Twisted-Python] WebWidgets and Deferreds.
by Chris Armstrong Nov. 24, 2001

Nov. 24, 2001

Ok, riddle me this, glyph (or anyone else who knows about this). Why do we need Deferreds to be a special-case in WebWidgets? Why can't _all_ widgets be displayed only right when they're needed? RenderSession could just take a Widget, and display() it (and the widgets that display() returns) in order.. Is there some sort of performance issue here, maybe? Maybe I'll try implementing this, and send a patch to be looked at. -- <TomG> I'm in the wrong channel. -- … [View More]

If the protocol isn't specifically designed to deal with exceptions (For example, dynamic web content or PB protocol exceptions) then it's undefined behavior and the connection should be dropped. Bot behavior should be implemented in a layer above the IRC protocol, if there is a place for a catch-all exception handler. I … [View More]

[Twisted-Python] Sites, protocols etc.
by Magnus Heino Nov. 21, 2001

Nov. 21, 2001

Hi. I've got a basic app using widgets up'n'running. Still, it would be nice with an example of how it is meant to be used. Surely someone must have anything? Doesn't even have to work... I just want to know that I'm doing things The Right Way. Next question: Can I serve both xmlrpc and http from the same application/site? I guess I can, but I havent figured out how... Thanks, /Magnus
