Zwiki 0.25 released
by Simon Michael 02 Dec '03

02 Dec '03

Zwiki 0.25 is available at http://zwiki.org and http://zope.org/Members/Simon/Zwiki . See http://zwiki.org/ReleaseNotes for the details. Summary: Fully-functional non-DTML wikis are now supported and default; refactored default skin with macros, CSS and SkinnedFolder support; more zwiki features available in CMF/Plone; quicker comments, improved search, easy tracker setup, much code refactoring, etc. Lots of cleanup and changes this month, including some very positive skin, DTML and hierarchy progress. We've run into a wall with catalog conflict errors but that should be solvable. Dare I say it, the docs situation is showing signs of improvement too. Jump in and help if you can. Happy holidays and merry christmas! 3:-)

Epoz 0.7.1 released - critical bug fix for 0.7.0
by Maik Jablonski 02 Dec '03

02 Dec '03

Hi to all, I've just released Epoz 0.7.1 - a critical bug fix for all people who installed Epoz 0.7.0 (the XHTML-release of Epoz). What is Epoz? Epoz is a cross-browser-wysiwyg-editor for Zope and Plone. It works out of the box with InternetExplorer >= 5.5, Mozilla >= 1.3, Firebird >= 0.7 and other "Gecko"-based browsers with a recent engine. Is Epoz now XHTML-compatible? Yes, it is. It uses the mxTidy-module (download http://www.lemburg.com/files/python/mxTidy.html) over XMLRPC to transform the HTML to XHTML on the fly. There was a severe bug in the 3.party-vcXMLRPC-modul which resulted in Mozilla truncating the XHTML to 4096 characters, so please upgrade if you installed Epoz 0.7.0 or data may be lost. Can I see a demo? http://www.zfl.uni-bielefeld.de/personal/mjablonski/epoz/ Where can I download Epoz? http://www.zope.org/Members/mjablonski/Epoz/ What are the changes in the 0.7.x-release? 0.7.0 - added support for mxTidy to produce nice and valid xhtml-code. - added site-hook EpozPostTidy, so you can change the output of Epoz with an additional script / external method. Useful if you want to clean up or rewrite (absolute) links etc.pp. - added missing language support for Plone. 0.7.1 - fixed critical bug: Mozilla truncated contents to 4096 bytes received from EpozTidy over XMLRPC due to a bug in the string-code of the vcXMLRPC-library. - fixed critical bug: if mxTidy found errors in html, an empty document was returned to Epoz. JavaScript-alert informs the user about critical errors in document. And what is this thing with Epoz 0.x and Epoz 1.x? There's an ongoing effort on http://sf.net/projects/epoz to develop a next generation of Epoz (1.x), based on new ideas and on a new design. Guido Wesdorp, Philipp von Weitershausen and Paul Everitt have done a great job working on Epoz (1.x). The developement of the original Epoz (0.x) will continue because I run several applications which I can't easily update to Epoz (1.x) in the near future. Keep zoped, Maik Jablonski -- German Zope User Group / Deutsche Zope User Group http://www.dzug.org/

PyCon DC 2004 - Registration about to open!
by Steve Holden 01 Dec '03

01 Dec '03

Dear Python User: You have probably been wondering why you haven't yet heard that PyCon has opened its doors for registration. Well, we are a volunteer organization, and it often takes more time than anticipated to put things together. Welcome to the world of open source :-) I am happy to be able to tell you that thanks to sterling work by Trevor Toenjes we are now in a position to accept your registrations. All you need to do is navigate to http://dc2004reg.pycon.org/ and make the appropriate entries. This year we all have the opportunity to add a PSF donation to the registration fee, and I hope many of you will follow my example and donate a little extra to assist the Foundation in its goals. There is still lots to be done -- for example, we are *also* late with the system to accept submissions, so the original December 1 deadline will be extended by at least a month to ensure that everyone gets plenty of chance to submit papers telling us what they've been up to with Python. We are also encouraging students to attend the conference by giving them a significant reduction from the standard fee, and we hope that this will result in even wider participation by the educational community. Last year was an exciting departure from the traditional "professional" conference format, and I hope that we will be able to improve on it next time. I look forward to seeing you there! Sincerely Steve Holden Chairman PyCon DC 2004

ANN: TextIndexNG 2.03 released
by Andreas Jung 01 Dec '03

01 Dec '03

I just released TextIndexNG 2.0.3. This is an optimization release :-) and features a new internal hashing datastructure that avoids needless reindexing of objects that have not changed. This should improve reindexing performance significantly. Upgraders should reindex their TextIndexNG2 indexes after installation. This release is available from Sourceforge: http://sourceforge.net/project/showfiles.php?group_id=50052 Docs are available as usual from http://www.zope.org/Members/ajung/TextIndexNG -aj

ANNOUNCE: Pound - reverse proxy and load balancer - v1.6
by Robert Segall 30 Nov '03

30 Nov '03

This is to announce the release of Pound v1.6. Changes in this version: - Callback for RSA ephemeral keys: - generated in a separate thread - used if required this will allow certain versions of IE to work correctly with Pound/SSL. - New X-SSL-cipher header encryption level/method - Added CheckURL parameter in config file - perform syntax check only if value 1 (default 0) - Allow for empty query/param strings in URL syntax - Additional SSL engine loading code - Added parameter for CA certificates - CA list is sent to client - Verify client certificates up to given depth - Fixed critical security vulnerability in syslog handling: this may allow a remote exploit, though none has been observed to date. The danger is minimised if you run Pound in a root-jail and/or as non-root user. Anyone using a version prior to 1.6 should upgrade as soon as possible. The software is at version 1.6 (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

Zope X3 Milestone Release 4 is available for download
by Stephan Richter 26 Nov '03

26 Nov '03

Hello everyone in the Zope community and beyond, We are pleased to announce that Zope X3 MS4 is out of the door. Much work has been done since the last release in June, 2003, including major fundamental refactorings of the Component Architecture, I18n/L10n, filesystem syncing, and new TTW capabilities. Get it now! You can find a source and Windows binary archive at the URL below. URL: http://dev.zope.org/Zope3/Milestone4 Here the release notes: Zope X3 Milestone Release 4 is available for download What is Zope X3? It's Zope 3 "experimental". This is the release that will provide the new features of Zope 3 without any Zope 2 support. Zope 3.0 will provide support for Zope 2 content and products, probably using conversion utilities of some sort. Backward compatibility notes - If you have any add-on prodycts that used the old context-wrapper or "context awareness" APIs, you will need to update these use the new, and much simpler, location API. See zope/app/interfaces/location.py. - If you have add-on products that register views or resources using the view or resource directives from the zope ZCML namespace, you will need to change the value of the 'type' attribute to refer to a request type, rather than a presentation type. - If you have an add-on product that defines new layers, you need to use the zope:layer or browser:layer directive to define the layer before you use it in a skin definition or a view or resource definition: <browser:layer name="rotterdam" /> - If you had a local (through the web) adapter service, you will need to recreate it and reactivate your adapter registrations. - If you had a local (through the web) view service, you will need to create a local presentation service and reactivate your page or view registrations. Features - Changed the way presentation components are managed. o The view, resource, and skin services have been combined into a new presentation service. o Views and resources now adapt requests. They are registered for request types rather than presentation types. - Refactored the way interfaces, declarations and adapters are implemented. We now use a cleaner architecture that no-longer requires a caching mechanism beyond what's provided by the underlying data structures. This has led to a significant speed up for Zope 3. - Refactored the way location-related events are generated and handled. For more details, see: http://dev.zope.org/Zope3/LocationRelatedEvents http://dev.zope.org/Zope3/SimplifyObjectLifecycleAndLocationEvents - Refactored the way object location is modeled. Zope 3 no longer uses context wrappers. Instead, objects have __parent__ attributes that reference their containers. Objects that don't maintain these attributes themselves are warpped in persistent proxy objects that do so. For more details, see: http://dev.zope.org/Zope3/ParentGeddon - Added catalogs. Catalogs can be used in two-ways: o Site-wide utilities A catalog is created in a site-management folder and registered as a named utility. o Local content objects. A catalog is added to a regular content folder. - Added object fields. Object fields provide a simple composite field mechanism. An object field is defined by a schema and, thus, can contain sub-fields. - Added working widgets for list fields. List fields contain a sequence of monogenous values. - Improved forms error reporting. Error messages now appear next to fields where errors occured. - Major fixes to the TAL I18n-Namespace support. Almost all fixes were backported to Zope 2.7 as well. - Templated Pages support for a <disabled script> tag, that allows inline Python code. The <disabled script> tag can be used in other TAL sources as well, but is turned off by default. - Internationalized all Zope 3 (Python, ZCML and Page Templates) user-readable strings. Zope 3 was then localized to German and partially to Spanish, Brazilian Portuguese and French. - Implemented explicit message ids in ZCML - New Persistent/Mutable Schemas allow us to generate Schema-based interfaces through the Web. - New local Menu Service and Content Component Definitions allow you to create simple Content objects TTW. - Major fssync improvements. The commands to use now are "zsync" and "zbundle". New flags include: copy, login (+ new options for checkout), logout, mkdir, resolve, revert. fssync behaves now very similar to SVN. - Introspector uses the Interface service now, instead of the ++module++ namespace. - Refactoring and cleanup of the schema/form code. - Improvements to the OnlineHelp, which has been deactivated for this release since it is broken since the recent geddons. - ZODB 4: Changed serialization logic to support persistent proxies. Added an add() method to Connection and allowed it to run during commit(). - In the future, Zope 3 will use ZODB 3, which will support new-style classes, since the development of ZODB 4 stopped in late summer. - Various improvements to ZConfig Miscellaneous - Progress with the TUV-IT security accredidation - Many maintainance work and bug fixes. Much thanks to everyone who contributed to this release: Jim Fulton, Christian Theune, Marius Gedminas, Tim Peters, Jeremy Hylton, Fred Drake, Sidnei da Silva, Philipp von Weitershausen, Steve Alexander, Guido van Rossum, Barry Warsaw, Albertas Agejevas, Viktorija Zaksiene, Andreas Jung, Anthony Baxter, Phillip Eby, Richard Jones, Tom Cameron, Kevin Littlejohn, Stuart Bishop, Andy Hird, Peter Simmons, Christian Theune, Adam Summers, Stephan Richter, Chris McDonough, Garrett Smith, Godefroid Chapelle, Paul Roe, Kiki Pruvot, Don Baarda, David Fregon, Rob Zaar, Jan Smith, Richard Volpato, Roger Ineichen, Gary Poster, Bjorn Tillenius, Martijn Faassen, Chris Withers, Paul Everitt, Dominik Huber Requirements Zope3 requires Python 2.3.2 or later. You might get a segfault when shutting down the Zope servers. This is due to a bug in weakref and will be fixed in the upcoming Python 2.3.3 release. You can safely ignore the segfault. Downloads - Source release: "ZopeX3-0.0m4.src.tgz", http://dev.zope.org/Zope3/ZopeX3-0.0m4.src.tgz. Follow the instructions for building from source in README.txt. - A windows binary release: "ZopeX3-0.0m4.win32.zip", http://dev.zope.org/Zope3/ZopeX3-0.0m4.win32.zip. This is an "in-place" build. Just unzip it and run it. Use Python 2.3.2 and skip the building part of the instructions. Regards, Stephan and the Zope 3 team

PloneCollectorNG 1.0 RC1 released
by Andreas Jung 25 Nov '03

25 Nov '03

I am pleased to announce the release of PloneCollectorNG 1.0 RC1 (PCNG) PCNG is a bugtracking system for Plone. It is based on the concepts and ideas of CMFCollector and CMFCollectorNG but it is a complete re-write. One major highlight of this new version is the built-in TTW editor for Archetypes schemas. This means you can edit the complete fields for your issue (field types and widgets) through-the-web including the use of schemats etc. Another goal of the new implementation was to focus on security. So I dropped the old workflow and created a new one (which is much simpler). The codebase is very small and generic and therefore very much extensible for the future. Changes since 1.0 beta 3: - lots minor UI changes and tweaks - full i18n support for German Requirements: - Plone 2.0 (Plone 1.X untested) - Archetypes 1.0.1 (AT 1.2 is *not* supported yet; please don't ask me when AT 1.2 well be supported. It's done when it is done) ATTENTION: If you upgrade from an earlier release of PCNG you should re-install the product using the Add/Remove products in the Plone setup. ATTENTION TO USERS of Plone 2.0 beta 3: portal_workflow has been removed in Plone 2b3 from the action provider list. This is a *big problem* and will be fixed in the next Plone release. To fix this: - remove the "deleteActionProvider()" call in CMFPlone/setup/ConfigurationMethods.py line 175 - *recreate* your Plone 2.0 site (if created *with* Plone 2.0 beta 3) - there is currently no support from my side to re-enable the portal_workflow as action provider for Plone sites created under Plone 2.0 beta 3 Wiki and Download: http://www.zope.org/Members/ajung/PloneCollectorNG Cheers, -aj

Re: Epoz 1.0 released!
by Guido Wesdorp 21 Nov '03

21 Nov '03

Epoz 1.0 released! The Epoz team is proud to present version 1.0 of Epoz, a 'document-centric' client-side editor for Mozilla, Netscape and Internet Explorer. Epoz is a WYSIWYG (What You See Is What You Get) editor written in JavaScript, and was originally created by Maik Jablonski. This version has been completely rewritten by Paul Everitt, Guido Wesdorp and Philipp von Weitershausen (and several other contributors, for a complete list refer to the CVS log on Sourceforge). The objective of the rewrite was to improve stability and extensibility and make it usable as an editor for content management platforms such as Silva. Epoz can be also used in combination with Zope, Plone (although integration code won't be complete until version 1.1) and all webservers that support the HTTP PUT command. The Epoz rewrite was sponsored by Infrae, the makers of Silva. Epoz is: o Easy to integrate - Epoz can be easily integrated into Zope based servers as well as non-Zope webservers. Currently there is integration code for Zope 2, Zope 3, and Silva. We hope to add code for integrating Epoz into Apache, MMBase, Interchange, and more in the near future. o Easy to customize and extend - Epoz can be customized and extended in several ways. For simple modifications much of the configuration can be set as attributes on the editor iframe, while buttons, tools and layout can be changed via the CSS. For larger customizations there's a simple JavaScript plugin API, and also the core has a clean and solid architecture to allow full extensibility. o High-tech and up-to-date - Epoz uses CSS in favor of HTML for layout and presentation. It supports asynchronous saving to the server. It sets event handlers from code instead of from the HTML (excepting the toolbar), which makes the code a lot cleaner. It uses DOM functionality to build up HTML. On those and other fronts it tries to use the most modern standardized techniques available on all supported browsers to ensure a good user-experience and clean code. Epoz can be downloaded from the project page on SourceForge: http://sourceforge.net/projects/epoz There is a mailinglist: http://lists.sourceforge.net/lists/listinfo/epoz-development as well as an issuetracker to report bugs: http://codespeak.net/issues/epoz/ If you have a bug to report, please post it on the issuetracker after first checking it hasn't already been reported. If you'd like to contribute to Epoz, either with JavaScript patches or plugins or with integration code, or if you have a question or remark, please post a message on the mailinglist. The Epoz team would like to thank the following people and organizations: - Maik Jablonski for starting the project and inspiration - Infrae for sponsoring the project - The ETH university in Zürich for feedback and sponsoring Infrae - Holger Krekel for allowing us to use his infrastructure - All beta testers and everybody who has contributed to the project We hope Epoz is a nice experience and that you will enjoy using it as much as we did writing it! Cheers, the Epoz team .
