overrides.zcml and localization in Zope 2.9
by Doyon, Jean-Francois 06 Jun '06

06 Jun '06

Hello, I'm trying to override Zope's localization mechanism with my own, as documented here: http://codespeak.net/z3/five/i18n.html And am not having any luck. <configure xmlns="http://namespaces.zope.org/zope" xmlns:i18n="http://namespaces.zope.org/i18n"> <i18n:registerTranslations directory="locales" /> </configure> <configure xmlns="http://namespaces.zope.org/zope"> <adapter for="zope.publisher.interfaces.http.IHTTPRequest" provides="zope.i18n.interfaces.IUserPreferredLanguages" factory=".i18n.URLLanguages" /> </configure> from zope.i18n.interfaces import IUserPreferredLanguages from zope.interface import implements class URLLanguages(object): implements(IUserPreferredLanguages) def __init__(self, context): self.context = context def getPreferredLanguages(self): return ['fr'] As best I can tell, the method never gets called, I've added print and raise statements and so on and yet nothing ever seems to happen. With the above example HTTP_ACCEPT_LANGUAGE still always ends up being en-us ... Also, locales/fr.mo exists. What am I missing here?

Templates vs DTML
by Dennis Allison 06 Jun '06

06 Jun '06

We've been using DTML but we are at a point where we could move to page templates. We are starting a major restruture and rewrite of much of the system and are debating moving to ZPT. Performance is potentially a major issue. We are using Zope 2.9.X, will eventually move to Zope 2.10.X and Five. Python 2.4.X. Has anyone done any benchmark comparison of the two design choices? For the same functionality, which performs better. No flame wars about which is better, just information about performance.

Using PIL 'inside' Zope
by Jamie Bullock 05 Jun '06

05 Jun '06

Hi, Does anyone know of a way to use the PIL imaging library within a Zope instance. If i do from PIL import Image I get Module AccessControl.ZopeGuards, line 284, in guarded_import ImportError: import of "Image" from "PIL" is unauthorized. You are not allowed to access 'Image' in this context Anyway to change this restriction? Is it advisable to change it? PIL works fine when using it via an external method, but this is a bit cumbersome for what I need to do. Advice appreciated. Jamie

Re: Any known leaks in ExtFile and OpenFlow?
by Michael Vartanyan 05 Jun '06

05 Jun '06

Hi all, One of my Zope (2.8.4 on Python 2.4.2, SLES9) sites constantly hits the memory limit. It makes heavy use of two products - ExtFile (1.5.0) and OpenFlow (1.1.0). ExtFile class (of ExtFile) and workitem class (of OpenFlow) are leading the refcount list with a not-constant but overall increasing numbers of references. Refcounts for both reach numbers that are incomparably higher than the numbers of their instances in ZoDB. I wanted to ask if there are known leaks in these products before going into (painful) hunting and debugging leaks in my own code. Thanks!

How to set selected items in multi-select list from lines property
by John Schinnerer 05 Jun '06

05 Jun '06

Aloha, I have an "add" form where a user can add an object. In one part of the form, the user selects zero or more options from a multiple select list. The selected options populate a lines property of the object when the object is added. I also have an "edit" form where the user can later edit these same objects they've created. They can use the same multiple select list to change the selected options. Of course the previously selected options (in the lines property) need to be displayed as such when they first visit the edit form. So... I need to know how to display the multiple-select list in the "edit" form so that the options currently in the lines property are set as selected. I suspect there is some very slick way to do this, maybe with TAL alone...? So far I am only coming up with what seem to be cumbersome solutions that have unecessary overhead (comparing a list option with every element in lines property via python script to see if it should be set selected, and repeating for every list option)...is there a better way? Any help appreciated. thanks, John S. -- John Schinnerer - MA, Whole Systems Design ------------------------------------------ - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john(a)eco-living.net http://eco-living.net

The CMF developer community is pleased to announce the release of version 1.6.1-beta of the Zope Content Management Framework (CMF).

The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. As packaged, the CMF generates a site much like the zope.org site. The CMF is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. What's new in this release? The 1.6.1-beta release represents a pure bug fix/maintenance release without feature additions. The CMF-1.6.1-final release will form the basis for the upcoming Plone 2.5 release. Where do I get it?

left frame loads after a very long time
by Raphael Pesche 03 Jun '06

03 Jun '06

Hi, loading the ZMI with a browser is usually a rather long process but since we updated the OS on our machine (Suse 10.1 with GCC 4.1) the left frame (manage_menu) needs now more than 4mn to be loaded eating all the cpu. We use a ZEO-configuration with Zope-2.8.7. I installed the ZopeProfiler but can't figure out much of the output. The script "ClientStorage.py" is the one that takes the longest time by far. Any clues as to what might be wrong there or where I should have a look to understand the problem more deeply? Thanks in advance for any help. Raphael
