Ape 0.8 Released
by Shane Hathaway 29 Mar '04

29 Mar '04

Ape version 0.8 is ready. Ape now works with Zope 2.7 and can store the root database. The number of concepts in Ape has been reduced, making it easier to learn and extend. Ape, the Adaptable Persistence Engine, adapts Python objects to storage on the filesystem, in relational databases, or practically anywhere else. It combines the advantages of transparent object persistence with arbitrary databases and formats. Ape comes with two default mapper configurations, a Zope2-filesystem mapper and a Zope2-SQL mapper. http://hathaway.freezope.org/Software/Ape/ Shane

by Alexander Limi 24 Mar '04

24 Mar '04

Plone 2.0: The Most Productive Content Management System The Plone Team announces the release of Plone 2.0, the next generation of its rapidly growing open source Content Management System. After an impressive launch, Plone continues to garner attention. Plone was the highest-voted open source project for the O'Reilly pavilion at COMDEX and was the only open source system invited to the Jupiter Content Management Conference. Widely deployed worldwide, Plone has been downloaded over 100,000 times, with many companies throughout the world offering consulting, customization, and support. "We chose Plone for many of our client projects because of its out-of-the-box ease-of-use and features," says Barry Reicherter, Vice President for Porter Novelli Interactive, a division of the international media communications firm. "We could customize it quickly for our clients' needs, while retaining the intuitive interface and accessibility. That's critical for our clients' success. We're looking forward to the improvements that Plone 2 offers, especially for larger organizations." Porter Novelli Interactive has delivered Plone solutions as part of its mission to deliver marketing-driven value to their clients, such as the recent launching of usepropane.com, a national site designed and managed entirely with Plone, and backed with a $25 million ad campaign. Plone 2.0 offers significant productivity gains for content managers and developers. It includes an intuitive interface and out-of-the-box features such as time-based content publishing and role-based authoring and publishing. Particularly compelling for many organizations is that Plone is available without licensing costs and offers a similarly stable, feature-rich CMS environment as competing commercial systems costing hundreds of thousands of dollars. There are dozens of new features and improvements in Plone 2.0, including: * A user interface that has been streamlined and improved. Testing has shown it to be both flexible and intuitive. It takes existing features such as sophisticated workflow, wizard-style forms and content editing and offers many improvements. * Sites deployed on the Plone 2.0 platform conform with government standards for website accessibility as the Plone interface is compliant with Section 508 and WAI-AAA standards. * The entire Plone interface is customizable using standards-compliant programming and graphics tools. * Add-on enhancements can now be installed, uninstalled, and examined with a one-click process. Trying out new additions is a snap. * For enterprise users, user/group management features allow sophisticated security configurations. User data can come from many external sources, including LDAP, ActiveDirectory, or relational databases. Workspaces allow intuitive group collaboration. "The Plone community continues to amaze everybody who chooses to be a part of it" said Alan Runyan, co-founder of Plone. "Many open source projects are only attractive to hard core software developers but the Plone project has attracted varied groups such as artists, musicians, usability specialists, and industry gurus. The Plone project management team is thrilled at the number of entities that offer training, full support, hosting, and consulting services These services provide a level of security and professionalism that allows Plone to fit the needs of organizations around the world." About Plone Plone is the leading Content Management System for the award-winning Zope application server. Supported by thousands of developers from around the world, it is one of the most sophisticated, popular, and easy to use Enterprise Content Management Systems on the market today. Plone provides a highly customizable, server-side architecture, and boasts a simple yet flexible API. Plone is highly scalable, stable, extensible, and has open standards as its core mentality.

ANNOUNCE: Pound - reverse proxy and load balancer - v1.7
by Robert Segall 24 Mar '04

24 Mar '04

This is to announce the release of Pound v1.7. Changes in this version: - Fixed bug in X-SSL-CIPHER description: the description no longer causes problems by breaking the request - Changed README to stx format for consistency - Addedd X-SSL-certificate with full client certificate contents - changed the old-style responses to support "streaming" mode. This should help especially OpenACS users: - Improved the response times on HTTP/0.9 (content without Content-length) - Improved response granularity on above - using unbuffered BIO functions now - Fixed problem with IE/SSL (SSL_set_shutdown) - Avoid error messages on premature EOF from client - Fixed HeadRemove code so all headers are checked without exception - Improved autoconf detection and fixed various compile-time problems - Moved from select() to poll() in order to avoid limitations on the number of descriptors The software is at version 1.7 (production quality). Further testing (especially under heavy loads), improvements and suggestions are welcome. What is Pound (from the Web page) - a reverse-proxy: it passes requests from client browsers to one or more back-end servers. - a load balancer: it will distribute the requests from the client browsers among several back-end servers, while keeping session information. - an SSL wrapper: Pound will decrypt HTTPS requests from client browsers and pass them as plain HTTP to the back-end browsers. - an HTTP/HTTPS sanitizer: Pound will verify requests for correctness and accept only well-formed ones. - an HTTP/1.1 to 1.0 proxy. - a fail-over-server: should a back-end server fail, Pound will take note of the fact and stop passing requests to it until it recovers. - a request redirector - it will pass client requests to separate groups of servers, based on required URL and the presence or absence of headers (pattern matching) Pound was specifically developed to serve as a front-end for multiple instances of Zope running on top of a common ZEO storage, but can be used with any other web server. A patch for the Python source of z2.py is available as part of the distribution to allow using Pound's SSL capabilities. Pound is currently in use in several medium to large volume sites and seems to be holding up quite well: largest reported site does about 5.5 million requests per day, peaking at over 450 requests per second. The speed is well superior to other, equivalent solutions, the configuration is much simpler and the necessary resources (CPU, RAM, disk) are much, much lower. Pound is distributed under the GPL. For further information, download, etc. please see http://www.apsis.ch/pound Pound now has its own mailing-list - just send a message to pound-subscribe(a)apsis.ch in order to join. Enjoy and let me know how it works for you. -- Robert Segall Apsis GmbH Postfach, Uetikon am See, CH-8707 Tel: +41-1-920 4904

PropertyTools 2.0 released
by Maik Jablonski 19 Mar '04

19 Mar '04

Hi, yesterday I've released PropertyTools - the successor of PropertyObject/-folder. What the hell are PropertyTools good for? If you want to "prototype" object-oriented database-applications with Zope, PropertyTools will provide you with handy data-storages. If you get the idea behind PropertyTools (and the object-factory-tool AbracadabraObject), you can create simple database-applications based on the ZMI within 5 minutes (of course you can create complex applications with PropertyTools too, I've done some complex apps like univerisity-course-management-systems with lots of relations etc. based on PropertyTools in the last months which run nicely in production). If you spend just some additional minutes, you'll be done with a customized webapplication within 2 hours...:) Think of PropertyTools-Objects as lockable & sortable & workflowable ZMI-propertysheets which can be synchronized via a virtual class-attribute (object_type). Additionaly you can define different templates for rendering each virtual PropertyTools-class. Creating a simple faq-database or a contact-database with PropertyTools can be done in minutes, not hours... I'll promise! What's changed to 1.x? - Added PropertyFile besides PropertyObject & PropertyFolder - Added simple demo.zexp (a faq-database) to demonstrate how to use PropertyTools. - Updated property-sheets to Zope2.7-templates. - Refactored all code for managing the propertysheets into a new Mixin-Class PropertyTools. - Added additional Top/Buttom-Buttons for ordering properties. Thanks to Steve McMahon for his patches! - Fixed a bug in manage_changeProperties. Keyword-Arguments were broken for empty REQUESTs. Thanks to Abel Deuring! - Removed support for published-attribute. Added support for simple workflows based on PythonScripts. - Removed PropertyObjectDescription. Where can I download PropertyTools? http://mjablonski.zope.de/PropertyTools (and you should also download) http://mjablonski.zope.de/AbracadabraObject Keep zoped, Cheers, Maik
