Zope Debugger 0.8.0 Released!
by Chris Withers 28 Sep '05

28 Sep '05

Zope Debugger is an enhanced version of pdb for use with Zope. It can be used simply by inserting the following lines in any python code you'd like to debug, including Script (Python)'s and FSPythonScripts: from Products.zdb import set_trace set_trace() It requires no changes to Zope, CMF or Plone or any funky interaction with any specific kind of editing software. All you really need to do is insert the snippet above and make sure your Zope instance is running in foreground mode.

Vancouver Python and Zope: Next Meeting Oct 2nd
by Andy McKay 26 Sep '05

26 Sep '05

The Vancouver Python and Zope user groups next meeting is on Oct 4th, at the usual place, ActiveState at 7. Mishtu Banerjee will be giving a talked entitled "Desperately Seeking Abstraction" "I built an SQL query generator (as part of a larger project) based on the underlying abstraction of representing data models as "networks". It's a nice illustration of abstracting a particular analysis pattern (in this case, we're abstracting the pattern of multi-table inner joins, which is one of the most common ad-hoc query types)" For more information see our website: http://www.vanpyz.org Mailing list: http://www.agmweb.ca/cgi-bin/mailman/listinfo/list -- Andy McKay Enfold Systems, LLC http://www.enfoldsystems.com

[ANN] TextIndexNG 3.0.7 released
by Andreas Jung 24 Sep '05

24 Sep '05

I am pleased to announce the release of TextIndexNG V 3.0.7. 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 3.0.6: - support for thesauruses - converters: massive improvements for OpenOffice documents (patch by Raphaël Poss) - converters: RTF support added (patch by Raphaël Poss) 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 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.

[Ann] ZopeProfiler 1.6 -- find out how Zope spends its time
by Dieter Maurer 21 Sep '05

21 Sep '05

ZopeProfiler allows you to profile your Zope execution and thereby find out how Zope spends its time. Such a profile is an essential prerequisite for most kinds of optimizations. ZopeProfiler provides profiles both on a high (Zope) as well as a low (Python) level. This version fixes a bug in the "c_exception" dispatch. The bug can lead to assertion errors in Python's "profile.py" module when an exception happens in a C implemented function. The same bug will be fixed for Python 1.4.2 (nevertheless, the bug needs to be fixed in ZopeProfiler, even if Python 1.4.2 is used).

[Ann] CompiledExecutables 0.4 -- save compilation time on startup
by Dieter Maurer 21 Sep '05

21 Sep '05

CompiledExecutables defines a set of executable objects that are precompiled and the compilation stored either in the ZODB or in the file system. Storing the compilation result avoids expensive recompilation. This can drastically speed up access to the first pages after startup -- especially for large CMF based sites. Currently implemented objects are: CompiledPageTemplate, FSCompiledPageTemplate and FSCompiledPythonScript (stock Zope stores the compilation result for PythonScript itself). This is the first version that runs with a stock Zope (tested with 2.8.1). Previous releases had run only for our locally modified Zope version.

[Ann] ManagableIndex 1.1; IncrementalSearch2 0.2
by Dieter Maurer 17 Sep '05

17 Sep '05

These releases provide Zope 2.8/ZODB 3.4 compatibility. Nothing else changed with respect to the previous releases. ManagableIndex is a flexible indexing framework. It comes with efficient, flexible, highly customizable field, keyword, path, range and word indexes and allows to easily build new index types on top of it. IncrementalSearch2 is a low level search engine for the evaluation of "and", "or" and "not" queries. While the corresponding search in Zope's ZCatalog (and other standard search engines) treat document lists (found in indexes and intermediate results) as sets and combine them with set operations, IncrementalSearch2 treats them as incrementally computed sequences of documents (respectively incrementally looked up for those found in indexes). This incremental hit determination can drastically reduce the amount of objects touched during the search (if the search contains highly specific "and" subqueries). As a result, the search may be much faster (up to several orders of magnitude) and pose a lower load on the ZODB caches.
