I'm pleased to announce the release of ZODB 3.4 final. This corresponds to the ZODB that will ship in Zope 2.8. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.4 Note that there are two Windows installers, for Python 2.3 (2.3.5 is recommended) and Python 2.4 (2.4.1 is recommended). Only minor changes were made since ZODB 3.4b1. See the news file for details: http://zope.org/Products/ZODB3.4/NEWS.html Note that ZODB 3.4 does not support any version of Zope 2.6 or 2.7. Current Zope 2.8 and Zope 3 development use ZODB 3.4. The ZODB 3.3 line is officially retired (3.3.1 final was the last release in the 3.3 line).

PloneLive 1.0 Available Now!
by Michel Pelletier 04 Jun '05

04 Jun '05

Plone Live is the result of a year of work, full- and part-time, of the two authors, Michel Pelletier and Munwar Shariff, our technical editor, Jean Jordaan, and our copy editor, Amy Kesic. But this book is more than what you are holding (or reading on the screen), because this book is live; every month, the authors add new content and fix typos, responding to the feedback our readers leave on our site, http://plonelive.com. Over the next year, this book will tackle one of the greatest challenges for any book about modern, open source software: remaining current. Using the traditional publishing method, books quickly become out-of-date and irrelevant, rather than remaining up-to-date, useful references. By updating this book every month, SourceBeat has created a unique publication format that solves these problems with traditional publication methods. First, it's hard to get a book about a complex piece of open source software 100% correct; in fact, almost impossible when one or two authors and one technical reviewer must often document a system built by dozens or perhaps hundreds of programmers. By creating orderly, feature-based releases each month, the book can evolve over time to cover more and more complex features of the software, and we can catch errors quickly in the first few updates. Second, open source software, like Plone, often does not follow a hard-and-fast feature plan, but instead adds new, innovative features as they are thought up by creative developers trying to solve real world problems. By updating the book each month, the book can quickly adapt to cover any new technologies or trends that emerge from the community of users. Books that are released once every year or two cannot follow or easily adapt to these trends. Third, like open source software, books have communities. However, traditional books have a large disconnect between the reader and the author because there is no way for the reader to get feedback to the author. Even if they could, there are seldom clear, easy-to use-channels for redistributing books or errata. By creating the “live” book format, SourceBeat is creating a new way for readers and authors to make better books cooperatively. You can buy this book online from Amazon at: http://www.amazon.com/exec/obidos/ASIN/0976553406/002-2820793-0614428% 29%2Cas/104-8538093-5697530

CPSSharedCalendar 1.0.0 beta 2 released
by Lennart Regebro 03 Jun '05

03 Jun '05

June 2, 2005 -- Nuxeo is happy to release CPSSharedCalendar 1.0beta. CPSSharedCalendar is an advanced, flexible calendaring component for Zope and CPS3. It allows CPS users to access personal calendars using a web interface. Events on the calendar can be shared between multiple users, as a user can invite others to an event. This event will then appear on the calendar of the invited users as well. Features of the CPSSharedCalendar include among others: * a web interface for managing calendars, * integration with iCalendar clients (Apple iCal, Mozilla Sunbird, KOrganizer...) using the iCalendar protocol, * invitation workflow, * meeting support, * meeting helper that looks for free time, * etc. CPSSharedCalendar is built on a reusable core and is thus not just for CPS. It has been written from the ground up to be easy to integrate with other Zope 2 platforms such as Plone and Silva, and with portability to Zope 3 in mind. Its python core component (CalCore) can even be used outside of Zope altogether. For more functional and technical information, see the CPSSharedCalendar web site: http://www.cps-project.org/sections/projects/calendar_server CPSSharedCalendar can be downloaded here: http://www.cps-project.org/static/misc/CPSSharedCalendar-package-1.0.0-b2.t… Look at the README.txt file in the package for more information on how to install CPSSharedCalendar. If you'd like to help with CPSSharedCalendar development or porting to other platforms, please join the cps-devel mailing list at http://lists.nuxeo.com/mailman/listinfo/cps-devel (a dedicated list will be created if needed in the future). -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.cps-project.org/ -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.cps-project.org/

[ANN] TextIndexNG 3.0.2 released
by Andreas Jung 02 Jun '05

02 Jun '05

F I am pleased to announce the release of TextIndexNG V 3.0.2. TextIndexNG V 3 is a complete new implementation based on Zope 3 technologies and can be used both in Zope 2.8 or 2.7 (with Five) or in Zope 3. What's new? - multi-field indexing and query support - multi-lingual support - configurable converters (through ZCML) - new indexing API (allowing you to hook your custom content types with TextIndexNG through Zope 3 adapters). Changes since V 3.0.2: - multi-field query support added: the query parser now accepts queries where you can search within multiple fields using a single query e.g. 'title::phrase(The Zope Book) and author::or(michel amos)' which searches for all documents with the exact title 'The Zope Book' and where the author field contains 'michel' or 'amos'. See doc/README.txt for details on the query syntax. - new extension module 'txngstemmer' providing language dependant stemmer support based on the Snowball stemmer library. This is a reimplementation of the older PyStemmer extension module based on the new Snowball reimplementation allowing a much cleaner and easier integration. Outstanding compilation problems and problems with unicode should be finally resolved. Stemmer support will be added to TextIndexNG in a later version. Requirements: - Zope 2.8 or Zope 2.7 (+ Five) or Zope 3 (Zope 3 has nothing like catalogs yet) TextIndexNG V3 will *not* run with bare Zope 2.7 installations without Five (and this will not be changed in the future). Download: http://sf.net/projects/textindexng For installation and documentation issues refer to doc/README.txt from the archive. It's basically the same procedure as with former versions except you *need* to recompile the extension modules. Windows binaries of the required extension modules are currently not available (any volunteers?). TextIndexNG V 3 is published under the GPL.

ANNOUNCE: Pound - reverse proxy and load balancer - v1.9
by Robert Segall 01 Jun '05

01 Jun '05

This is to announce the release of Pound v1.9. Changes in this version: - Added the VerifyList configuration flag (CA root certs + CRL) - CRL checking code - RewriteRedirect 2 - ignores port value for host matching - Added -c flag (check-only mode) - Added -v flag (verbose mode) - Added -p flag for pid file name Problems fixed: - fixed a potential buffer overflow problem (in checking the Host header) - added call to SSL_library_init - added a check for MSIE before forcing SSL shutdown - X-SSL-Cipher header is added only if HTTPSHeaders is non-zero - added code for shorter linger on badly closed connections (IE work-around) - fixed the locking for session checking (mutex_lock/unlock) The software is at version 1.9 (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 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: +41-44-920 4904
