ZODB3 and ZEO2 beta releases
by Jeremy Hylton 04 Oct '02

04 Oct '02

I am pleased to announce the second beta releases of ZODB3 and ZEO2. These are the last beta releases. We expect to release the final versions in two weeks. ZODB is an object database for Python that provides transactional persistence while requiring few, if any, changes to application logic. ZEO is a client-server storage system for ZODB. The ZEO2 package is released on its own and as part of ZODB3. The separate release is for Zope users, who already have ZODB. You can get source releases from http://www.zope.org/Products/StandaloneZODB and http://www.zope.org/Products/ZEO. The ZODB3 release requires a C compiler, while the ZEO2 release is pure Python. The components you get with the ZODB3 release are as follows: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - Supporting modules such as ExtensionClass - The persistent BTrees modules - ZEO (versions 1 and 2) - Experimental Berkeley storages - Updated documentation The beta release contains roughly the same version of ZODB that will be included in Zope 2.6. The two releases are not directly coordinated, so there may be some subtle differences. Many people have contributed to ZODB3. Special thanks to Toby Dickenson for the new ZODB Connection cache. Many people at Zope Corp. have contributed code and tested unreleased versions. There were many changes and bug fixes to ZEO since the last beta release, but very few changes to ZODB. See the NEWS.txt file for details. Jeremy

SC-Track Roundup 0.5.0 - an issue tracking system
by Richard Jones 03 Oct '02

03 Oct '02

================================================= SC-Track Roundup 0.5.0 - an issue tracking system ================================================= Note: If you are upgrading, you *must* read doc/upgrading.txt! Roundup requires python 2.1.1 for correct operation. Support for dumbdbm requires python 2.1.2 or 2.2. 2.1.3 and 2.2.1 are recommended. Roundup includes a Zope interface and now uses Zope's Page Templates for its HTML templating. A lot has been done since 0.4.4: - new backend for metakit (thanks Gordon McMillan) - new backend for sqlite - new backend for gadfly (it's as done as it's going to get) - added Boolean and Number types - fixed the journal bloat, re-enabling useful link journal events - full-text search may also search certain String properties - entire database export and import (including files) - implemented new per-user access control mechanisms (Permissions, Roles) - switched templating to use Zope's PageTemplates giving much more flexibility - made web interface more generic, robust, give nicer errors, ... - revamped look and feel in web interface including cleaned up CSS usage - switched to cookie-based sessions for web authentication - saving of named search queries - lots of documentation cleanups including an updated customisation document with los of examples and a new maintenance guide - roundup-server may be a daemon now (fork, logfile, pidfile) - many, many more bug fixes, cleanups and minor improvements (see CHANGES.txt) This final 0.5.0 release fixes the following problems: - fixed style for alternating rows in user lists - a couple of other minor bugs - updated demo to use 0.5 codebase Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/projects/roundup Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.1+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and six database back-ends (anydbm, bsddb, bsddb3, sqlite, metakit and gadfly).

[ANN] TextIndexNG 1.05beta2 release
by Andreas Jung 03 Oct '02

03 Oct '02

I am pleased to announce the release of TextIndexNG 1.05 beta2 This version is also the release candidate for the official 1.05 release. TextIndexNG is a new pluggable index for the ZCatalog and is the most feature complete solution for fulltext inexing under Zope. TextIndexNG enhances the fulltext indexing capabilities of Zope by providing the following features: * support for document converters (HTML, PDF, WinWord, PowerPoint, Postscript). Custom converters can be easily added * stemmer support for 12 languages * optional support for right truncation * similarity search (soundex, metaphone support) (for English) * NEAR search * phrase search * pluggable query parsers (two parsers included) * stop words support * new test tab for interactive testing * faster than Zopes old TextIndex * full unicode support (new) * normalization support (new) * new similarity algorithm: double metaphone (new) * new TXNGSplitter * new vocabulary browser Changes: * added full wildcard support for CLLexicon and StandardLexicon * rewrote Stemmer module (now fully unicode compliant) * unittests code cleanup * query evaluation refactored * Parser API changed to return a parse tree instead of a Python expression * new parse tree evaluator added * PyQueryParser: now accepts a minus sign as prefix of a word to indicate NOT. Searching for "foo -bar" will be recognized as "foo AND NOT bar". In addition the syntax for "ANDNOT" has been changed to "AND NOT". * stopword handling through registry * added double metaphone algorithm for similarity search * Splitter handling changed: The new TXNGSplitter has been added. It supports both strings and unicode strings and supercedes the functionalities of all other existing splitters for Zope. TXNGSplitter is the only splitter that will be used by TextIndexNG. The "index numbers" options has been removed both from the splitter and the ZMI. In addition the splitter now accepts an optional set of characters that are recognized to be valid inside words. This allows you to index common words like "C++" or "python-22.lib" when you specify "+.-" as valid word characters. * Python C extensions compile now under Windows (Binary distribution will be available for Windows) * normalizer support added * full unicode support * the add form for TextIndexNG now uses the registries to obtain informations about registered complements instead of hardcoded values. * fixed problem with changed API of the Interface packages (backport from Zope 3 to Zope 2.6) * added vocabulary browser * lots of code cleanup * bug fixes... * add statistics tab to ZMI * fixed serious bug in TXNGSplitter due to missing encoding parameter * minor ZMI adjustments * using converters no longer raises an exception when a converter could not be found for the mime-type of a document * using document converters did not work due to a changed API call * added Finnish stemmer * improved CMF support: TextIndexNG is not able to index foreign file format stored as "Portal File" using the DocumentConverters. "Portal File" objects are indexed if the index name is 'SearchableText". This is a big improvement since you can now use to search through text objects and word, pdf etc. inside your CMF site with the "SearchableText" index. * added stopword files for ten languages * minor fixes inside the TXNGSplitter Requirements: * Zope 2.5 or Zope CVS trunk checkout Documentation: * http://www.zope.org/Members/ajung/TextIndexNG/wiki Download: * http://www.zope.org/Members/ajung/TextIndexNG/ or * http://sourceforge.net/project/showfiles.php?group_id=50052 --------------------------------------------------------------------- - Andreas Jung http://www.andreas-jung.com - - EMail: andreas at andreas-jung.com - - "Life is too short to (re)write parsers" - ---------------------------------------------------------------------
