[Twisted-Python] Twisted 1.0.4 - `im' bug report
by pinard＠iro.umontreal.ca April 21, 2003

April 21, 2003

Hi. I intend to become a Twisted novice. At the beginning of the road, I got, unpacked and installed Twisted 1.0.4. Then, I called `im' in a shell, and in the window that appeared, pushed on button `Join Group', to get: ----------------------------------------------------------------------> <GtkObject of type GladeXML at 84a2398> initialized!

[Twisted-Python] Lore vs. latex2html: Fight to the Finish
by Moshe Zadka April 21, 2003

April 21, 2003

Dear Twisted developers, I have started converting Thinking Like a Computer Scientist in Python to Lore, to try and see what Lore is missing. It has been a most education experience. The two prime things Lore is currently missing for lossless conversion (of the specific chapter I tested) are: * EPS images support * Indexing support However, beyond that, I am interested to know which looks better: latex2html: http://www.ibiblio.org/obp/thinkCSpy/chap01.htm Lore: http://twistedmatrix.com/… [View More]

[Twisted-Python] Twisted 1.0.4 - Problem with `domtemplate.html'

Hi, people.

[Twisted-Python] Thinking backwards, design ideas
by dansan April 19, 2003

April 19, 2003

Fellow twisters, I have finally read all that seemed necesary to get a good feel of twisted! and I have finally been able to implement a few 'play' programs. I have a project I'd like to write, and I have always tought about it in the normal "use a library" fashion (in oppisition to the "use a framework"). My idea is to create a program that is a tournament manager, it works kind of like this: * Accepts connections (there are 2 types, admin, regular). * Listen to the admin connection -… [View More]

[Twisted-Python] links to .xhtml files in doc/index.html
by Lee Harr April 19, 2003

April 19, 2003

Hi; Is there a reason why the links to the sections in doc/index.html point to .xhtml files instead of the .html files that are actually there? Here is a patch that I applied to my local copy of the docs. It makes more sense to me this way.... 16:58 >cvs diff -u index.html Index: index.html =================================================================== RCS file: /cvs/Twisted/doc/index.html,v retrieving revision 1.4 diff -u -r1.4 index.html --- index.html 11 Feb 2003 00:32:35 -0000 … [View More]

[Twisted-Python] feedback requested -- flow.py goes beta
by Clark C. Evans April 19, 2003

April 19, 2003

Abstract: > The flow module implements cooperative multi-tasking using iterators (easily created with generators) and Twisted's event reactor. The flow module also includes support for incrementally returning query results from Twisted's database connection pool. While this module does _not_ require generators (a python v2.2 feature), applications of the module are best demonstrated with generators. Status: > The flow module (flow.py) is currently checked … [View More]

[Twisted-Python] PHP Support
by Moshe Zadka April 19, 2003

April 19, 2003

Summary: In PHP 4.3, /usr/bin/php4 is not CGI compatible. Twisted assumes it is. Currently, the current version in Debian is 4.2, which is why is was not a problem for most of the core Twisted developers. Others, more "edgy", operating systems like Gentoo have already begun to feel the repercussions. I talked to Adam Conrad (infinity on Freenode), who is the Debian PHP maintainer, about this issu, and relayed his thoughts to glyph. We actually do need to solve this problem. Following are the … [View More]detailed conversation transcripts, mildly edited by me for formatting. [re 4.3, on #debian-devel] <_moshez> but my understanding is that now the default binary thinks it is not a CGI <_moshez> so doesn't give CGI headers by default <_moshez> and you need to build with magic flags to force the binary to give CGI headers. <_moshez> now, when Twisted runs /usr/bin/php <php script>, *it really wants those headers* <infinity> Twisted should be running /usr/lib/cgi-bin/php4 <_moshez> infinity: does /u/l/c-b/p4-cgi exist in all 4 versions? <infinity> "All 4"? <_moshez> infinity: yes. 4.2.xs <infinity> Oh. Yes. <infinity> It exists all the way back to potato's 4.0.3 <infinity> _moshez : Various dists may package it differently, so if this an upstream thing, I'm not sure how best to deal with it. But in Debian, it always has been, and always will be in /usr/lib/cgi-bin/ <_moshez> infinity: I'll see what my upstream thinks, and if necessary I'll change it in my scripts <_moshez> infinity: the important thing for me is to be woody-compatible <infinity> _moshez : In fact, with 4.3, /usr/bin/php{,4} will be even less +CGI-compatible than it is now, so make sure to use the CGI one. :) <_moshez> infinity: I know that :) <_moshez> infinity: this is why I wanted this cleared before 4.3 :) <infinity> _moshez : Well, if this is for an httpd, a suggests might be nice, <_moshez> infinity: I may use Suggests: in twisted-web, then. [on #twisted] <_moshez> glyph: <infinity> Twisted should be running /usr/lib/cgi-bin/php4 <_moshez> glyph: this is only guaranteed to be the location for Debian, though <_moshez> glyph: I can deal with it in my scripts, or we can change it upstream +then. (I wish Enhances worked, I'd use it all over) * _moshez notes nobody commented yet on his ITP <glyph> _moshez: If you need to change it, upstream should have a way to configure it. I imagine this is sufficiently variable that it should be an argument to mktap web <_moshez> glyph: *you're* upstream <_moshez> glyph: whatever you decide is fine by me... <glyph> _moshez: I'm not going to fix PHP scripting right now, I do have more valuable things to be doing with my time :) <glyph> _moshez: but that's what I recommend the solution to be. <_moshez> glyph: if radix decides it's not worth his time, he should decide to either "leave as is" or "change to Debian default" <_moshez> glyph: either of those would satisfy me <glyph> _moshez: okay <glyph> _moshez: could you write about this to the list, actually? <glyph> _moshez: I think that we should have the issue talked about there, good raw material for a FAQ -- Moshe Zadka -- http://moshez.org/ Buffy: I don't like you hanging out with someone that... short. Riley: Yeah, a lot of young people nowadays are experimenting with shortness. Agile Programming Language -- http://www.python.org/ [View Less]

[Twisted-Python] Pair of prescription sunglasses left at PyCon sprint
by Christopher Armstrong April 19, 2003

April 19, 2003

I found a pair of prescription sunglasses on the table where the Twisted gang was sprinting. If anyone can claim them, send me an address to ship them to. Sorry for not posting about this earlier, I had forgotten about them and they just turned up. -- Twisted | Christopher Armstrong: International Man of Twistery Radix | Release Manager, Twisted Project ---------+ http://twistedmatrix.com/users/radix.twistd/
