December 2003 - Zope-Announce

FieldedTextIndex 0.1 Released
by Casey Duncan 30 Dec '03

30 Dec '03

I am pleased to announce the initial release of FieldedTextIndex, a new ZCatalog index based on ZCTextIndex. Its purpose is to allow indexing and searching of any number of textual content fields using a single index. The schemas of the content do not need to be known when the index is configured. The index will automatically add new fields as they are discovered in content. The idea is to replace a proliferation of small text indexes (one per searchable field) with a single one that provided better functionality and convenience. FieldedTextIndex is designed to work with any schema system. From CMF Dublin Core and humble property sheets to Zope 3 schemas (Zope 3 to Zope 2 integration left as an exercise for the reader ;^). With a simple glue script, fields can be collected and aggregated into the index (samples provided). Download At: http://zope.org/Members/Caseman/FieldedTextIndex Enjoy. -Casey

New book: Rapid Application Development with Mozilla
by Nigel McFarlane 26 Dec '03

26 Dec '03

Dear Zope Folk, Over here (there?) in the Mozilla community, we appreciate the various attempts you've made to combine Zope and Mozilla. Just a brief note to say that such work can now be attempted by mere humans, thanks to *embarrassed cough* my new book which covers the Mozilla side. See it at: http://www.amazon.com/exec/obidos/tg/detail/-/0131423436/ This time there's extensive hand-holding, tutorials, and clear and complete explanations - more than sufficient to get going easily, should you choose to do so. Guesswork has reduced and software stability has increased. For the skeptical, a non-Amazon review can be seen here: http://www.phppatterns.com/index.php/article/articleview/91/1/12/ Hope this helps. Good luck with your Zope work. New Mozilla-based applications are a topic of increasing interest over at mozilla.org lately. Do be in touch if Mozilla starts sounding attractive to you again. kind regards, Nigel McFarlane (author). -- --------------------------------------------------------------------- Nigel McFarlane nrm(a)kingtide.com.au Services: Analysis, Programming, Writing, Education Expertise: Software, Telecommunications, Internet, Physics Author "Rapid Application Development with Mozilla" ISBN 0131423436

by Santi Camps 24 Dec '03

24 Dec '03

What is zetadb ============== zetadb is a python / zope tool that allows a rapid application development (RAD) of relational database oriented web applications. Currently, it implements PostgreSQL and MySQL support. Other database will be added in the future. It automatically generates transladable, user friendly, and database independent zope objects to maintain data over the web. It also allow generation of data-filled OpenOffice documents. Using zetadb you will be able to develop professional intranet / extranet business applications 4 or 5 times faster than using other more generalistic tools / languages More information and download: http://zetadb.sourceforge.net Databases supported =================== PostgreSQL >= 7.2 and MySQL >= 4 What's new in version 0.8.3 =========================== - Added support for ZPsycopgDA adapter - Added support for MySQL, using ZMySQLDA adapter. MySQL 4 is required - Database independent SQL. Z SQL objects are generated using postgresql and different issues are converted on the fly - Some tests under zope 2.7, python2.3 and postgresql - Some tests under MS Windows and MySQL 4 - Workarround for the bug http://zope.org/Collectors/Zope/1135, when working with SESSION objects concurrently in multiple frames - New customizable menu object (thanks to Csok Tibor) - Read only fields (thanks to Csok, too) - Security checks in toolbars - Toolbar images are now placed in a unique "images" directory at application level, not duplicated in every toolbar - A lot of bugs fixed CAUTION: Applications developed under previous zetadb versions should be updated using the "Update Version" button in the applications properties tab. Otherwise, your objects will crash. You probable also will need to click "Build Objects" in your table managers to have all working fine -- Santi Camps http://zetadb.sourceforge.net

Zope.org operations and more...
by Rob Page 11 Dec '03

11 Dec '03

Hello everyone: We have done a fair bit of work in the last few weeks to address some of the community's recent concerns. In summary we've taken (or about to take) the following steps: - organized ourselves internally to start the process of involving the community in the ongoing development, operations and maintenance of Zope.org. You can find details on this effort at: - http://www.zope.org/About Related to this are two new documents explaining the site's service terms and privacy policy: - http://www.zope.org/TOS/TermsOfService - http://www.zope.org/TOS/Privacy - organized ourselves internally and developed some new procedures for managing trademark licenses. You can find details online at: - http://www.zope.com/Legal/TMProcedures In addition, we are going to experiment with a few mechanisms at improving the regularity, predictability and quality of communication we have with the Zope community. The first such experiment will be an IRC session as follows: - Tuesday, Dec 16, 2003, 11a-12p (US/EST GMT-5) on irc.zope.com in #zope-community Zope reps on the IRC session will include Rob Page, Jim Fulton, Brian Lloyd, Jens Vagelpohl and Shane Hathaway.

ANN: eGenix mxODBC Zope Database Adapter
by M.-A. Lemburg 11 Dec '03

11 Dec '03

________________________________________________________________________ ANNOUNCEMENT EGENIX.COM mxODBC Zope Database Adapter Version 1.0.7 Available for Zope 2.3 through 2.7 on Windows, Linux, Solaris and FreeBSD ________________________________________________________________________ INTRODUCTION The eGenix mxODBC Zope Database Adapter (Zope DA) allows you to easily connect your Zope installation to just about any database backend on the market today, giving you the reliability of the commercially supported eGenix.com product mxODBC and the flexibility of the ODBC standard as middle-tier architecture. Unlike Zope's ZODBC Zope DA, the mxODBC Zope DA works on Windows XP/NT/2000/98, Linux, Solaris and FreeBSD using the same interface on all platforms. The mxODBC Zope DA implements high performance thread-safe connection pooling and multiple physical connects per logical Zope connection. You can safely run Z SQL Methods in parallel, achieving a much better throughput than ZODBC Zope DA or similar Zope database adapters under heavy load. This makes it ideal for deployment in ZEO Clusters and Zope hosting environments where stability and high performance are a top priority. ________________________________________________________________________ FEATURES * Zope Level 3 Database Adapter: the mxODBC Zope DA is fully multi-threaded and can handle multiple connections to multiple databases. * Fully compatible to Z SQL Methods. * Drop-in compatible to the ZODBC DA: the mxODBC Zope DA provides the same interfaces as Zope's ZODBC DA to allow a smooth upgrade path from this simplistic adapater to the high performance mxODBC Zope DA. * Fully compatible to the Znolk SQL Wizard Product and other similar products relying on the common database schema access methods .tables() and .columns(). * Connection Pooling: physical database connections are pooled and kept open, to reduce the connection overhead to a minimum. This is especially important for high latency database connections and ones like Oracle which take a considerable amount of time to setup * Parallel Execution of Queries on a single logical connection: the mxODBC Zope DA can manage any number of physical connections on a single logical connection. This enables running truly parallel Z SQL Method queries -- a feature not available in other Zope DAs. * Robust Mode of Operation: connections which have timed out or go away due to network problems are automatically reconnected. * Cross-platform Connection Objects: The Zope DA will automatically choose the right platform specific ODBC manager for you. * Per Connection Adjustable ODBC Interface: mxODBC comes with many different subpackages to choose from on Unix. The Zope DA allows you to select these subpackages on a per-connection basis. * Per Connection Error Handling: you can tell each connection whether it should report ODBC warnings or not; furthermore all warnings and errors are made available as list .messages on the DatabaseConnection object. * Transaction safe automatic reconnect: when the DA finds that a connection has timed out, it automatically tries a reconnect and replays the transaction on the connection (unlike other DAs which break the transaction scheme by doing a reconnect without replay). * Built-in Schema Cache: this results in improved performance under heavy load. * Database Schema Access: all ODBC catalog methods are made available for much better database schema inquiry. The catalog methods allow building generic database interrogation or manipulation tools and facilitates writing database independent Zope products. * Lazy Connect: the mxODBC Zope DA only connects to the database backends when a connection is actually requested. This results in a better use of resources compared to other Zope DAs. ________________________________________________________________________ NEWS Version 1.0.7 includes the following changes and enhancements: * Zope 2.7.0 and Python 2.3 are now fully supported. * The connection pooling was made more robust to allow less capable ODBC drivers to work nicely with the mxODBC Zope DA. * A new option was introduced to let the mxODBC Zope DA return empty strings instead of None for SQL NULL values. This should simplify porting applications to the mxODBC Zope DA. * A problem with the MS SQL Server was solved which caused deadlocks under heavy load in some application settings. In short: mxODBC Zope DA is continuing to become the number one solution for integrating relational databases with Zope applications. ________________________________________________________________________ UPGRADING If you have already bought mxODBC Zope DA licenses, you can use these license for the updated version as well. There is no need to buy new licenses. The same is true for evaluation license users. ________________________________________________________________________ MORE INFORMATION For more information on the mxODBC Zope DA, licensing and download instructions, please visit our web-site: http://www.egenix.com/ You can buy mxODBC Zope DA licenses online from the eGenix.com shop at: http://shop.egenix.com/ ________________________________________________________________________ Thank you, -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Dec 11 2003) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,FreeBSD for free ! ::::
