Zope Page Templates

by Evan Simpson

The final release of ZPT 1.0 is ready, two days earlier than planned! We compensated by changing the name, from "Zope Presentation Templates". You can get it here .

ZPT 1.0 contains all of the features described in the project Wiki , including error handling. Please try them out, comment, and suggest changes and new features for the next round of development.

I have used Page Templates, along with WebDAV and DreamWeaver, to produce both a simple website and a complex ZClass-rich application without a single DTML Method. I liked it! It's looking like this is a truly sound design that will provide all of the benefits we had hoped for.

Many thanks to Guido, Barry, and the other Python Labs folks for a fantastic job on TAL, and to Todd Coram for shepherding this project to success.

Zope Status

by Brian Lloyd

Zope 2.3.1 has been released

Zope 2.3.1 contains fixes for a number of issues that have come up since 2.3.0, including the fixes for the issues addressed by the 02/23 and 03/08 hotfixes. It also contains a number of changes to address issues with ZCatalog. New data structures have been introduced to reduce the number of conflict errors caused by object indexing under some types of usage, and to reduce the amount of object database bloat that occurs when indexed objects change frequently.

The changes to ZCatalog have been designed so that newly created ZCatalog objects will take advantage of the new data structures. Existing ZCatalog objects will continue to work with the old data structures, but will not gain any of the benefits of the new code. It is possible to upgrade an existing ZCatalog object to use the new data structures by following the How-To

Many thanks go to those who helped exercise the new code and the catalog upgrade process during the beta cycle. Many thanks as well to Jim Fulton, Chris McDonough and Andreas Jung for their hard work and the prodigious amount of unit tests produced for the new (and old) Catalog code!

With the 2.3.1 release we have added a Linux Itanium binary distribution. Note that the Itanium binary is bundled with Python 2.0 instead of Python 1.5.2. This release (Zope-2.3.1-linux2-ia64-alpha.tgz) is named with "alpha" because it is the first for the platform. All unit tests pass and moderate testing has found no problems (actually, any problems you find are more likely to be issues with Zope on Python 2.0 rather than issues with the platform).

ParsedXML

by Karl Anderson

Parsed XML allows you to use XML objects in the Zope environment. You can create XML documents in Zope and leverage Zope to format, query, and manipulate XML.

Parsed XML consists of a DOM storage, a builder that uses PyExpat to parse XML into the DOM, and a management proxy product that provides Zope management features for a DOM tree.

ParsedXML for *nix is availiable Windows releases should be availiable soon.

The Content Management Framework

by Tres Seaver

Digital Creations is proud to announce that the 1.0 version of its Content Management Framework (CMF) is released

What is the 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.

Zope Web

by Ethan Fremen

Record Number of Visitors

March has already passed 5M hits. The previous high for an entire month is January with 4.95M hits. We should expect another 500k hits for Thur/Fri/Sat to finish March at 5.5M hits.

Progress on the Site

Now that the CMF and ZPT are released, work can begin in earnest on zope.org. The collaboration enhancement proposal will be a project by early next week: we expect to complete LDAP authentication by the end of next week.

After that, a CMF powered ZEO cluster will be brought online and we will begin the process of migrating content to the new site.
