by Robert Segall 04 Jul '02

04 Jul '02

This is to announce the release of Pound v0.5. Changes from previous version: - added support for configuration file options (instead of command-line flags). - major code restructuring and splitting. - better Makefile, with support for more systems. - some code fixes. 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 failover-server: should a back-end server fail, Pound will take note of the fact and stop passing requests to it until it recovers. For further information, download, etc. please see http://www.apsis.ch/pound The software is at version 0.5 (beta quality). Further testing (especially under heavy loads), improvements and suggestions are welcome. Pound is distributed under the GPL. 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

by Andy McKay 29 Jun '02

29 Jun '02

At last after much arm twisting by many people, the skin ZopeZen uses is now available as a (relatively) simple to install Zope product. It's not quite as good as Plone, but provides a fresh alternative to the default CMF or Squishdot. CMFZen is available here: http://zopezen.org/Source -- Andy McKay

ZFS 0.2.1 Released
by Andy McKay 26 Jun '02

26 Jun '02

ZFS 0.2.1 is now available, changes: - Large file support now actually works. Large files can be easily read and written from the local file system without memory bloat. - Support for mp3's if you have the Audio object installed (http://www.zope.org/Members/bowerymarc/Audio) - Deleting the ZFS object no longer deletes the path it points to - You can change where ZFS points to after it has been created. ZFS puts parts of Zope objects on the file system in an easily editable form without creating any new objects. It does this by hacking existing objects. Create and edit DTML objects straight from the file system! ZFS also increases performance by using ZODB caching when it can. The following objects are currently supported: - DTML Document - DTML Method - Python Script - Page Template - Folder - Image - File - Audio (mp3) For more information see http://www.zope.org/Members/andym/ZFS -- Andy McKay

ANNOUNCE: Pound - reverse proxy and load balancer - v0.4
by Robert Segall 25 Jun '02

25 Jun '02

This is to announce the release of Pound v0.4. Changes from previous version: - added code to disable a dead back-end server and to re-enable it once it comes back on-line. - added HTTP/1.1 chunked transfer mode. This presumes a back-end HTTP/1.1 server (which Zope is). - added client time-outs to prevent blatant denial-of-service attacks. - major code restructuring. 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 failover-server: should a back-end server fail, Pound will take note of the fact and stop passing requests to it until it recovers. For further information, download, etc. please see http://www.apsis.ch/pound The software is at version 0.4 (beta quality).

I am pleased to announce the release of TextIndexNG 1.05alpha1. TextIndexNG is a pluggable index for the ZCatalog that 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) 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 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 distriution 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 componenents instead of hardcoded values. * lots of code cleanup * bug fixes... Note: I will not be reachable during July because of a longer vaction. Please report any problems or bugs to the tracker on Sourceforge project page. --------------------------------------------------------------------- - Andreas Jung http://www.andreas-jung.com - - EMail: andreas at andreas-jung.com - - "Life is too short to (re)write parsers" - ---------------------------------------------------------------------
