April 2006 - Zope-Announce

[ANN] TextIndexNG 3.1.9 released
by Andreas Jung 29 Apr '06

29 Apr '06

I am pleased to announce the release of TextIndexNG V 3.1.9. TextIndexNG V 3 is a complete new implementation based on Zope 3 technologies and can be used both in Zope 2.8 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 in V 3.1.9: - added explicit check for the existence of the extension module so TextIndexNG3 will now fail at startup time with an exception instead of failing when creating new index instances - added UI support for valid word separators - added IObjectWrapper interface to core indexer engine to provide generic support for objects wrapped into some kind of wrapper. The purpose of the interface is to attach IObjectWrapper to wrapper classes using five:implements without having the need to modify exisiting code. - added support to deal better with indexing CMF content where the content object is wrapped inside a CMFCore.CatalogTool.IndexableObjectWrapper instance. TextIndexNG3/adapters/configure.zcml contains some commented configurations to attach a marker interface to IndexableObjectWrapper and in an addition an adapter to extract the wrapped object without having the need to add some CMF knowledge to the core indexing engine - added IExtensibleIndexableObjectWrapper for better integration with Plone (whose CatalogTool wraps Plone objects as ExtensibleIndexableObjectWrapper instances) - optimized internal datastructures (existing indexes should be cleared and reindexed) Requirements: - Zope 2.8+, Zope 3.2+ Download: http://sf.net/projects/textindexng Project page: http://opensource.zopyx.biz/OpenSource/TextIndexNG3 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 ZPL.

Technical Preview of Blob support in ZODB
by Christian Theune 29 Apr '06

29 Apr '06

Hi everybody, the ZODB team is proud to announce a technical preview of a Blob implementation for ZODB. Blobs are used to efficiently storage large amounts of binary data within a database. This implementation uses real files on the file system in combination with any ZODB storage (FileStorage, ...) and native support for ZEO clusters. It is efficient in terms of memory and CPU usage. As this is a technical preview announcement, please notice that this code might crash your computer, delete your data, and destroy your homework. Now, have a look at http://www.zope.org/Members/ctheune/ZODB-blobs.tar.gz This is a more or less recent ZODB 3.6 based branch with the additional Blob support. Check out the documentation in http://svn.zope.org/ZODB/branches/blob-merge-branch/src/ZODB/Blobs/ to see how to use the blobs. Feedback is welcome on zodb-dev(a)zope.org. You should be able to use this ZODB with any recent Zope version (2.9 and 3 trunk).

[Ann] Incremental filtering: a new way for catalog query optimization
by Dieter Maurer 09 Apr '06

09 Apr '06

Catalog searches are often slow. IncrementalSearch[2] can lead to drastic gains in query time. However, there is a large class of queries that cannot be significantly sped up: queries that contain huge Or subqueries involving bushy indexes, usually resulting from a time based subquery checking effectiveness and expiration (or other similar use cases) The newest versions of the companions "AdvancedQuery", "ManagableIndex" and "IncrementalSearch[2]" support incremental filtering to execute most such queries efficiently. With incremental filtering, the index is not use in the usual way. Instead, the remaining query parts determine a set of document candidates with is then filtered by the filtering subqueries, dropping documents not matched by these subqueries. Lets look at an example: Suppose you search for news containing 'AdvancedQuery' which are effective and not expired. The standard query would look like Eq('portal_type','News') & Eq('SearchableText', 'AdvancedQuery') & Le('effective', now) & Ge('expires', now) Internally, the "Le('effective', now)" subquery is expanded into "Or(*[Eq('effective', t) for t in 'effective' and t<=now]) which usually is huge. The "Ge" subquery is similarly expanded. The filtering query has the form Eq('portal_type','News') & Eq('SearchableText', 'AdvancedQuery') & Ge('expires', now, filter=True) & Le('effective', now, filter=True) When this query is executed, "Eq('portal_type','News') & Eq('SearchableText', 'AdvancedQuery')" determines a set of candidate objects. From this (probably small) set, objects not satisfying "expires >= now" and (then) "effective <= now" are filtered out. This way, we avoid the construction of huge Or subqueries. Of course, filtering is only efficient in some circumstances: usually, when the other query parts already garantee a small set of candidates and the filtering can avoid the construction of large intermediaries. Otherwise, filtering may not improve the query speed but increase it (maybe even drastically). Incremental filtering is a powerful optimazation tool, which need careful usage... You need the complete bundle ("AdvancedQuery", "IncrementalSearch[2]" and "ManagableIndex") when you want to use incremental filtering.

No time for foolery! Alas. Zwiki 0.52 has been released at http:// zwiki.org<http://zwiki.org/>. Zwiki is a free, powerful, easy to use and manage wiki engine for Zope 2; it works with standard Zope, CMF or Plone sites. Here is the news.

Upgrade notes A lot of skins code has changed. Your old wikis should keep working as before except: - if you have a customized ``recentchanges`` or ``searchwiki`` template you'll need to delete it or replace with the latest and re-customize - full/simple/minimal links in old custom skin templates will no longer work. - http://zwiki.org/HowToUseTheStandardSkinInPlone is now built in, if you made a "Zwiki" CMF skin you can delete it.

(AdoptRestructuredText) "As of today, RST is the default page type. Hurrah! And three cheers for trusty old STX, which served us well. It is still the page type of choice when you want to do stuff with embedded DTML or HTML." * fix error displayed on first comment to an RST page (#1233) * show "HTML (WYSIWYG)" in the editform when Epoz is available * remove editform's hard-coded gray background Page hierarchy * make backlinks form smarter * make singletons have same style as other links in contents Mail Issue tracking * don't bother showing "(property change)" in issue mailouts * provide a link to issuebrowser by default * make IssueBrowser show categories more usefully out of the box Translations * Thai translation started (Bunyawat Singchai) * update po files from rosetta and code, simplify file names General * namegeddon. File and class renames and re-ordering for clarity and better organization eg in wing ide * major refactoring of skin templates using macros, the same templates are now used for standard & plone skins (ViewGeddon) * document skin code in Views.py * use PageTemplateFile so view templates will reload in debug mode (macros still don't) * move all images to skins dir, use the standard zwiki page icon in plone * standard_error_message cleanups Urls: http://zwiki.org http://joyful.com http://joyfulsystems.blogspot.com http://zwiki.org/FreeHosting Happy Springcleaning! -Simon
