[Warning] "ManagableIndex" "Zope2.8+" incompatibility
by Dieter Maurer 05 May '06

05 May '06

WARNING! We hit an incompatibility of "ManagableIndex" with "Zope 2.8+". For Python new style classes, "__len__" instance attributes are no longer taken into account in the implementation of the "len" builtin. "len" now only looks for "__len__" class attributes. From "Zope 2.8+" on, all persistent Zope objects are instances of new style classes. Especially, "ManagableIndex"es are new style classes. "ManagableIndex"'s "__len__" instance attribute is no longer used by "len". Some Zope base class defines the class method "__len__" to return 1. As a consequence, "len" applied to a "ManagableIndex" always returns 1 in Zope 2.8 and later (until "ManagableIndex 1.3.1"). The badly behaving "len" can seriously confuse "AdvancedQuery" (and other similar query frameworks) that uses "len(index)" to guide the implementation of sorting. In our observed case, "AdvancedQuery" sorting was 3 to 5 times slower and read 3 times more objects than necessary. The bug is fixed in "ManagableIndex 1.3.1".

Five release fest: 1.2.4, 1.3.5, 1.4c and 1.5b released!
by Philipp von Weitershausen 03 May '06

03 May '06

The Five team is happy to announce the release of two Five bugfix releases, 1.2.4 and 1.3.5, as well as two Five betas, 1.4c and 1.5b today. What is Five ------------ Five is a Zope 2 product that allows you to integrate Zope 3 technologies into Zope 2, today. Among others, it allows you to use Zope 3 interfaces, ZCML-based configuration, adapters, browser pages (including skins, layers, and resources), automated add and edit forms based on schemas, object events, as well as Zope 3-style i18n message catalogs. We've tried to keep the Five experience as close to Zope 3 as possible, so this means that what you learn while using Five should also be applicable to Zope 3, and viceversa. More information about Five can be found on our website, http://codespeak.net/z3/five/. About Five 1.4 and 1.5 ---------------------- Five 1.4 and 1.5 are feature releases. They are basically equivalent except that Five 1.4 works with Zope 2.9/3.2 (only) and 1.5 works with Zope 2.10/3.3 (only). Five 1.5 will be included in Zope 2.10. Most important features are: * Added viewlet and content provider support. A big thanks to Alec Mitchell and his helpers at the Archipelago sprint for making this possible. * Add zope.formlib support. Please see ``doc/formlib.txt`` for more information. A big thanks to Jan-Wijbrand Kolman for this. * Port zope.testbrowser to Zope 2. You can now use Products.Five.testbrowser.Browser in functional tests. Much thanks to Brian Sutherland. * Add python-packages-as-zope-products support which basically allows for using any python package as a zope product without it having to live in Products/. Much thanks to Rocky Burt for this. Zope 2.10 and Five 1.5 are also a big milestone in the convergence of Zope 2 and Zope 3, for it is no longer necessary to mark classes with five:traversable and five:defaultViewable to enable Zope 3 view lookup functionality. A big thanks goes to Lennart Regebro and Michael Kerrin for making this possible! Changes in Five 1.2.4, 1.3.5 and 1.4c (compared to 1.4b) -------------------------------------------------------- * Made sure that events are fired as expected in add and edit forms. * Made sure LocalizerLanguages class normalized language codes to xx-yy, instead of xx_YY or xx-YY. * Fixed a problem with the new traversal look-up order and the root object (OFS.Application.Application). About the Zope 3 Base --------------------- Five is part of the *Zope 3 Base* project, which aims to offer an approachable area for developers of Zope 3 related software. More about the Zope 3 base and its projects can be found on the project website, http://codespeak.net/z3/.

Infrae announces the first public release of Document Library
by Martijn Faassen 03 May '06

03 May '06

Infrae announces the first public release of Document Library 3 may 2006 - Infrae has just released the first public version of Document Library (1.1b). Document Library is a document management application intended for the tracking of large amounts of documents in an organization. Document Library is open source. It is also open data: the contents of Document Library can be harvested using the standard OAI-PMH protocol and integrated with other applications. Integration with the Silva CMS using this technology is provided. What is the Document Library? Organizations deal with numerous documents, such as word processor documents and PDFs. These documents often reside on someone's computer and are not network accessible. Versions of documents are hard to track - the same document may be passed around using email in multiple versions over time. In large organizations it therefore becomes important to structure the flow of documents and present them in a common format. This is typically done using a document management system. Document Library is one such document management system. Information in the Document Library can be accessed using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), meaning that besides being open source, the Document Library is also a good example of an open data application. Because it is open data, the Document Library is easier to integrate with other applications, such as the Silva CMS or any other application capable of OAI-PMH harvesting. Features of the Document Library include: * Automatic conversion service: using OpenOffice, the Document Library can convert Word documents into PDFs and plain text, PDFs into plain text. The plain text version is important in that it allows for full-text indexing of document contents, and also makes documents more accessible to people with disabilities. * Publication workflow: documents only become available for harvesting and download after a review process. * Delegation of control: reviewers ("librarians") can be assigned to particular sections. * Dynamic access: authors have automatic access to all the documents that list them as an author. * Versions: multiple versions of the same document can coexist, one public and one under preparation. * Email reminder functionality: users receive emails of the progress of the document through the workflow. * OAI-PMH data provider: allows other systems to harvest document metadata using standard protocol. * Integration with Silva CMS (using OAI-PMH). * Fast upload and download integration with Apache using Tramline. * Easy overview screens for librarians. * Smart file upload user interface: files need to be uploaded only once even if rest of form needs to be amended. * Document Library is built using the powerful Zope 3 application server platform. Download The Document Library application can be downloaded from http://www.infrae.com/download/documentlibrary. Contact FMI contact Martijn Faassen, faassen at infrae com, +31 10 243 7051.
