RestrictedPython "globalization" change
by Tres Seaver 02 Jan '04

02 Jan '04

Evan, I was just looking with Shane at the code you added in November to address http://collector.zope.org/Zope/445 . It seems to me that this bit of majyk is just confusing, and makes PythonScripts even less like "normal" Python functions; the actual submitter could easily fix his script by adding 'global context' at the top. Did you have a deeper reason behind the change than the collector issue? If not, would you mind if we reverted, and updated the issue?

Unable to find Database adapter for MySQL
by Rajesh s shiggaon 02 Jan '04

02 Jan '04

Hi folks, I am using Zope 2.6.2 on windows platform. I am new to this ZOPE concept. I wanted to use the MySQL 4.0.13 also installed on windows. What i thought was if i am able to write python script to access the databse then easly i can make Zope to run that script. I downloaded the database adapter for the python ( i installed it seperately) and started playing with it and finally succeded in accessing the databse. But when i tried the same script in zope it gave an error because zope is using its own python application for which i am not able to add the datbase adapter. Is there any other way? If yes where can i find the adapter? Can anyone help me out in this regard. Thanks, Rajesh Rajesh Shiggaon

[ZConfig] wishlist
by Dieter Maurer 02 Jan '04

02 Jan '04

Today, I incorporated our Zope extensions into Zope 2.7 and had to determine how I can provide the necessary configuration through ZConfig. I feel the configuration process is not yet as modular as it should be? Let's explain what extensions I have: 1. an alternate "Transience" implementation for Zope sessions 2. a new log handler "rotated_logfile" (which performs automatic daily rotation with log files named "prefix.date") 3. a common piece of configuration used for communication between Zope and a "checkZope" process (which supervises that Zope responds sufficiently fast) I solved 1 and 2 by rudely modifying Zope sources ("zLOG/component.xml" and associated "handlers", "Zope/Startup/zopeschema.xml" and associated "handlers"). I do not yet have a solution for 3 but I probably will give the "checkZope" process the complete Zope schema and configuration file. Almost surely, it would not have been necessary to modify the "zLOG" configuration to get a "rotated_logfile" because components and sectiontypes provide enough modularity. However, schemas and configuration files seem not to be modular. I would like to compose schemas and configuration files from components: e.g. combine the standard Zope schema and a small schema for our extensions to form the schema used by the extended Zope, combine the configuration file from long living Zope settings (maintained in CVS), instance specific Zope settings (locally maintained) and configuration fragments used by Zope and other components (e.g. the "checkZope" process). I think, a general "include" function for schemas (including not only types but complete schemas) and configuration files could provide this kind of modularity. -- Dieter

more persistent mapping misery
by Chris McDonough 01 Jan '04

01 Jan '04

Hi folks, On the HEAD recently, a bunch of changes were made to the Persistence package. Notably, the Persistence.PersistentMapping module was removed in favor of a Persistence.mapping module. Unfortunately, there are instance pickles lying around in any CMF instance created prior to the changes (DiscussionItem's _container attribute is the one I found) which explicitly refer to Persistence.PersistentMapping.PersistentMapping. This name can no longer be resolved to a class. This breaks b/w compatibility. I "fixed" the issue by adding the following to the Persistence package's __init__.py: sys.modules['Persistence.PersistentMapping'] = sys.modules['Persistence.mapping'] That seems really ugly, though. Is there a better way to fix it? - C
