Zope Weekly News for December 6th
by ethan mindlace fremen 30 Mar '01

30 Mar '01

Welcome to the future: Zope 2.3.1 with the improved catalog, ParsedXML 1.0, the Content Management Framework 1.0 and Zope Page Templates 1.0 are unleashed upon the world. The opinions expressed in Zope News are solely the authors', and not the opinions of Digital Creations, The Zope Community at-large, or the Spanish Inquisition. If you or your company are doing something cool with zope, "submit it to Zope News", mailto:zope-web@zope.org for possible inclusion. And Now For Something Completely Different: ----- Upcoming Events The EuroZope crew is organizing a two day Zope only conference in Berlin on the 12th and 13th of July. Those interested in participating should join the discussion on the "EuroZope mailinglist", http://www.comlounge.net/mailman/listinfo/eurozope ----- 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", http://www.zope.org/Members/4am/ZPT . ZPT 1.0 contains all of the features described in the "project Wiki", http://dev.zope.org/Wikis/DevSite/Projects/ZPT , 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", http://www.zope.org/Products/Zope/2.3.1/ 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", http://www.zope.org/Members/mcdonc/HowTos/UpgradeToNewCatalog 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", http://www.zope.org/Members/karl/ParsedXML/ParsedXML 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", http://cmf.zope.org/download/CMF-1.0 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. Resources * The CMF "dogbowl site":http://cmf.zope.org. * The mailing list, zope-ptk(a)zope.org. List information and online signup "are available", http://lists.zope.org/mailman/listinfo/zope-ptk You may also "peruse the archives", http://lists.zope.org/pipermail/zope-ptk. ----- 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. -EOT-

ANNOUNCE: Zope 2.3.1 final released
by Brian Lloyd 30 Mar '01

30 Mar '01

Hello all, Zope 2.3.1 final has been released - you can download it from Zope.org: http://www.zope.org/Products/Zope/2.3.1/ 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.

It is possible to upgrade an existing ZCatalog object to use the new data structures by following the How-To at: http://www.zope.org/Members/mcdonc/HowTos/UpgradeToNewCatalog 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). **IMPORTANT NOTE** for users of the source release or users of the "diff" update releases Users of the Zope source releases should note that this release contains changes to C code. If you are using a source release (or the source diff update), be sure to run 'w_pcgi.py' or 'wo_pcgi.py' as appropriate before starting Zope to ensure that your binaries are rebuilt. Also, there has been some recent work on getting Zope to run on the Mac OS X platform. As a result of this work, the names of certain C extension modules were changed to avoid symbol name clashes on systems with a global dynamic module namespace. The result of this is that if you install a diff update over an existing installation, you need to do a few things manually: - If you are using a source release and apply the source update, visit the directories 'lib/python/BTrees' and 'lib/python/Shared/DC/xml/pyexpat'. In each, run 'make clean' and remove any .so files in those directories before rebuilding the extensions. - If you are running a binary release and have applied the diff update for your platform, before restarting Zope visit the 'lib/python/BTrees' directory and remove any .so (or .pyd) files that do *not* have names beginning with an underscore and in the directory 'lib/python/Shared/DC/xml/pyexpat', remove the file 'pyexpat.so' (or .pyd) For more information on what is new in this release, see the CHANGES.txt and HISTORY.txt files for the release: http://www.zope.org/Products/Zope/2.3.1/CHANGES.txt http://www.zope.org/Products/Zope/2.3.1/HISTORY.txt Note that we have also posted "diff" updates as .tgz files that will let you easily upgrade an existing 2.3.x site. These updates are available for those currently using the 2.3.x source release or the 2.3.x binary releases. To apply a differential update to your site: - download the appropriate .tgz file from zope.org - shutdown your Zope process - copy the .tgz to your Zope directory and extract it - SEE THE NOTE ABOVE!! - run w_pcgi or wo_pcgi *if you are not using a binary release* - restart your process Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com
