ZODB 3.2.4 (final) released
by Tim Peters 25 Oct '04

25 Oct '04

I'm pleased to announce the release of ZODB 3.2.4 (final). This corresponds to the ZODB (and ZEO) that shipped with Zope 2.7.3 (final). You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.2 Note that 3.2.4 incorporates a major change in semantics: it's incorrect to attempt to close a connection when objects from that connection are still in a modified state, and 3.2.4 raises the new ConnectionStateError exception in such cases. 3.2.4 also incorporates a significant ZEO performance fix, and a number of smaller bugfixes. See the news file for details: http://zope.org/Products/ZODB3.2/NEWS Note that ZODB 3.2.4 does not support Zope 2.7.2, because the Zope 2.7.2 publishing subsystem is an example of application code that didn't always finish a transaction before closing connections. ZODB 3.2.4 can be used with Zope 2.7.3. Note that ZODB 3.2.4 does not support Zope X3 or Zope 2.8 (they require ZODB 3.3).

[ANN] PloneCollectorNG 1.2.4 released
by Andreas Jung 24 Oct '04

24 Oct '04

I am pleased to announce the release of PloneCollectorNG 1.2.4 (PCNG) PloneCollectorNG is a Plone-based bugtracking solution and framework. Changes since V 1.2.3: - minor bugfixes - applied Kapil's patch to provide a better subclassing support for PCNG - fixed URL of quicklinks in search portlet - searches could not be saved properly - all workflows removed the assigned users from an issue if the issue state changed into a final state (defered, resolved, rejected). The workflow tool must be recreated in this case to fix the problem for existing PCNG instance (Configuration -> Maintenance) - email notifications now contain a References: and In-Reply-To: header to provide a better sorting within your email client - notification_policies.py: fixed AT accessor problem - removed most of the AT magic introduced in earlier releases. PCNG now uses ManagedSchema from !Archetypes instead of !PCNGSchema which introduced a lot of dependencies and pain over the last releases. The current implementation should now be in sync with all upcoming AT releases. - **WARNING**: every !PloneCollectoNG instances must be updated through **Configuration -> Maintenance -> Update Collector schema for all issues** - **WARNING**: backup your Data.fs before performing an upgrade "Documentation Wiki":http://www.zope.org/Members/ajung/PloneCollectorNG "Download":http://sourceforge.net/project/showfiles.php?group_id=55262&pack age_id=96051

Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.0a1. You can download the sources and the Windows version from http://www.zope.org/Products/Zope/2.8.0a1/ Some new features of Zope 2.8: - Zope 3.3 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites. - Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection. For more information on what is new in this release, see the CHANGES.txt files for the release: http://www.zope.org/Products/Zope/2.8.0a1/CHANGES.txt WARNING: the 2.8.0a1 is not thought for production purposes. Use this version for development and evaluation only. Due to the major changes in Extension Classes and ZODB there is a risk that some things are broken or do not work as they should (ZClasses are currently broken). Backup your Data.fs *before* trying 2.8.0a1. Please bring all the bugs you found to the Zope bugtracker at http://collector.zope.org/Zope For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: http://www.plope.com/Books/2_7Edition/InstallingZope.stx Thanks to everyone having contributed to this release.

Infrae extends Python, Zope, Silva, and Railroad with OAI-PMH facilities
by Martijn Faassen 14 Oct '04

14 Oct '04

OAI Pack: a full stack of Open Archives services October 14, 2004 – Infrae is pleased to release extensions for Python, Zope and the Silva CMS for harvesting web-based repositories exposed using the OAI-PMH standard (Open Archives Initiative Protocol for Metadata Harvesting). In addition we are announcing an extension for the Railroad content repository software for exposing existing Railroad systems as OAI-PMH harvestable repositories. The individual components enable organizations to harvest, index and present data from any OAI-PMH repository, and also allow the setting up of a new repository with Railroad. Railroad, Silva and these extensions are open source. The Open Archives Initiative Protocol for Metadata Harvesting is a well-established standard in the content management and library science worlds gaining in importance. It provides an application-independent interoperability framework for metadata exchange between online parties. Many academic libraries and other organizations expose OAI-PMH compliant repositories to the web that can be harvested. The OAI-PMH standard defines the following parties and software components: * A ‘Data Provider’ such as an academic library runs a Repository that supports OAI-PMH as a means of exposing metadata information about resources, for instance academic publications. * A ‘Service Provider’ uses Harvester software to harvest metadata from such Repositories. The harvested metadata can be used to provide valued-added services, such as a website that allows browsing and searching through a catalog. Infrae has extended Silva so it enables users to browse and search harvested metadata, further enriching the extensive feature set of this open source CMS. An organization that uses Silva can easily become an OAI-PMH Service Provider. In the process, Infrae also developed a module for accessing OAI-PMH compliant repositories in Python, and developed a sophisticated harvesting and indexing system for using harvested metadata in Zope. These reusable components are designed to be building blocks for other Python or Zope-based applications. Infrae has also extended Railroad with a service to turn it into an OAI-PMH compliant server. Railroad is a standards-based content repository for digital media and corresponding metadata. It’s designed to be easy to integrate with content management systems and other client software, and has already been integrated with Silva and Plone. By using Railroad, an organization can easily become an OAI-PMH Data Provider. Infrae calls this full stack of OAI-PMH services the OAI-PMH Pack. It is possible to use a combination of Silva and Railroad to become both Service Provider and Data Provider, but since the OAI Pack builds on an interoperable protocol, the components can also be used individually.
