How to set the request dict variable by tal ?
by fowlertrainer＠anonym.hu 15 Dec '03

15 Dec '03

Hello zope, I want to set the request's title variable (REQUEST.set('title','F\xf5menü'), but by TAL, not pyscript. But it is not working: <p tal:define="global request/title python: string 'F\xf5menü'" tal:replace="nothing"/> What a good syntax of my tal ? Thanx: KK -- Best regards, fowlertrainer mailto:fowlertrainer@anonym.hu

RestructuredText Backport 1.04 optparse Difficulties
by Steve McMahon 14 Dec '03

14 Dec '03

I've had some difficulties with the RestructuredText backport for Zope 2.6x v1.04 under Zope 2.6.2, Python 2.1.3. First, it installs at lib/python a copy of optparse.py that tries to import optik. optik.py, though, is in the docutils subdirectory, and invisible. Moving optparse.py to docutils solves that problem. Then, trying to render a structured text page produces the error "AttributeError: 'docutils.optparse' module has no attribute 'TitledHelpFormatter'". Indeed, the version of optik.py included with the backport lacks TitledHelpFormatter. Can I just go find another version of optik.py that has the function? Or, will that fail under python 2.1.3? By the way, the files in the backport tar are readable only by owner. Naively following the instructions "To install the package you need to unpack the archive in the top-level folder of your Zope installation," will result in a dead Zope. Either the tar or instructions need fixing. Thanks!

Python 2.3.2 compiled with --without-doc-strings
by Edward Muller 13 Dec '03

13 Dec '03

the --without-doc-strings configure option for python 2.3.2 means: The interpreter can be compiled without any docstrings for the built-in functions and modules by supplying --without-doc-strings to the configure script. This makes the Python executable about 10% smaller, but will also mean that you can't get help for Python's built-ins. (Contributed by Gustavo Niemeyer.) (From http://www.python.org/doc/2.3/whatsnew/node20.html) Is there any known problems using a python interpreter compiled with way and zope 2.7.0-b3 (or any other version of zope for that matter)? -- Edward Muller - http://www.interlix.com - "Open Source Specialists" Dedicated Zope Hosting - Web Hosting - Open Source Consulting Network & PC Service & Support - Custom Programming Phone: 417-862-0573 - Cell: 417-844-2435 - Fax: 417-862-0572 Jabber: edwardam(a)jabber.interlix.com - AIM: edwardam453 - ICQ: 287033

Refreshing modules imported into external methods
by Michael Hartl 13 Dec '03

13 Dec '03

I'm having trouble getting Zope to refresh modules imported into my external methods. I've googled at length, read the fine manual, and searched the list archives, all to no avail. Here is the situation: external method file foo.py (located in /path_to_Zope/Extensions): import bar def foo(): return 'foo' + bar.baz() Python module bar.py (located on my PYTHONPATH): def baz(): return 'bar' Now if I look at http://localhost:8080/foo, I see 'foobar', and if I edit foo.py to change 'foo' to 'fu', my browser (after refreshing) displays 'fubar'. The problem is that when I edit bar.py and change 'bar' to 'baz', I still see 'fubar', not 'fubaz'. In other words, Zope incorporates changes to my external method (foo.py), but not to its imported module (bar.py). It seems that Zope is caching the result of importing bar.py, because when I restart Zope the changes to bar.py show up in my browser. Restarting Zope after every change to an external module is a possible but extremely cumbersome solution to my problem. Does anyone know how to get Zope to re-import modules that have changed? I tried removing the Python bytecode (bar.pyc in this case), but that didn't work. I might be able to avoid this problem by developing a Zope product and forcing my method to be volatile using _v_, but many of the modules I want to import are for general use and are not Zope-specific. I am loath to tie them to Zope. Michael ===== Michael Hartl http://www.michaelhartl.com/ __________________________________ Do you Yahoo!? New Yahoo!

ZServer crash, Zope 2.6.2b3 RH9
by Dennis Allison 13 Dec '03

13 Dec '03

RH9 has had major problems with programs that use threads. I just experienced a server crash (ouch!) which looks like it may be due to RH9 threading, but I am not sure. And, of course, there's not much to go on in the logs, there's no chance of reproducing the situation, etc. Basically Zope died at line 241 in ZServer/HTTPResponse.py. This is in the __init__ method of the ChannelPipe class (and "Experimental" pipe from ZPublisher to a ZServer Channel). The error was ZServer Server Error: exception.TypeError, attribute name must be a string: file: $SOFTWAREHOME/ZServer/HTTResponse.py line: 241 repeated many times. ZServer eventually tries to close the channel (uncaptured Python exception), but the error persists. Shutdown of Zope was normal and restarting cleared the problem. Has anyone else seen this kind of behavior? I'll file a bug report on it if it happens again.

Re: [Zope] Returning a PageTemplate within a Disk-based Product always returns the aq_parent, not the ZPT itself

If you're talking about your browsers address bar, this will be the > same as the original request to your product instance, since you are > staying within the same HTTP request (when returning the page, instead > of redirecting) Hello Peter, by "show", I mean the URL in browser's address bar. When calling the method defined my product, I come from the URL: http://localhost:8080/MyProductInstance/authors/Add_Author.html So, if I stay in the same HTTP request, shoudn't it be http://localhost:8080/MyProductInstance/authors/Add_Author.html when calling the python method to return the page template ? -nico

IVR and Zope

Hi, Any experience around on an IVR (voice server for phone) using Zope based logic and voice media ? I've no experience in that field and dunno where how to start investigating on that problem. Many thanks in advance for any hint and pointer. -- Gilles Lenfant Pilot Systems - 66, rue de Provence - 75009 Paris Tel : +33 1 44 53 05 55 - www.pilotsystems.net Hébergement Zope et Plone gratuit - http://www.objectis.org

External Editor & Homesite+
by Philip Kilner 13 Dec '03

13 Dec '03

Hi List, Am using External Editor - but with "Homesite+.exe" (as bundled with DW MX). The editor works fine, but will not edit two files at once - on reading the docs, this may be because the name of the executable has changed from "homesite.exe" or "homesite5.exe" to "homesite+.exe", while the Homesite plugin for EE is looking for the old filenames. Is anyone aware of a workaround for this? Or am I drawing the wrong conclusion as to the source of my problem? -- Regards, PhilK Email: phil(a)xfr.co.uk / Voicemail & Facsimile: 07092 070518 "the symbols of the divine show up in our world initially at the trash stratum."
