[Ann] ZopeProfiler: high and low level timing statistics
by Dieter Maurer 02 Apr '03

02 Apr '03

ZopeProfiler provides profiling support for the development of Zope applications. It can derive both high and low level timing statistics (Zope object call and Python function call level, respectively). Unlike with the standard Zope profiling support, Zope runs normally in multi-threaded mode. Statistics gathering can be enabled/disabled dynamically via the ZopeProfiler object in the Control_Panel. This objects supports most features of Python's pstats.Stats timing analysis class and is much smarter than the standard Zope profiler. Should the features be insufficient, then statistics data can be saved to files and later analysed with Python's Stats class.

ANN: eGenix mxODBC Zope Database Adapter, Version 1.0.0
by M.-A. Lemburg 28 Feb '03

28 Feb '03

________________________________________________________________________ ANNOUNCEMENT EGENIX.COM mxODBC Zope Database Adapter Version 1.0.0 (for Zope 2.5 and 2.6) ________________________________________________________________________ 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/2000/98/95, Linux and Solaris using the same interface on all platforms. The mxODBC Zope DA implements 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 performance than ZODBC Zope DA or similar Zope database adapters under heavy load. This makes it ideal for deployment in Zope 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. * 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. ________________________________________________________________________ MORE INFORMATION For more information on the mxODBC Zope DA, licensing and download instructions, please visit our web-site: http://www.egenix.com/ ________________________________________________________________________ Thank you, -- Marc-Andre Lemburg eGenix.com Professional Python Software directly from the Source (#1, Feb 28 2003) >>> Python/Zope Products & Consulting ... http://www.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ Python UK 2003, Oxford: 32 days left EuroPython 2003, Charleroi, Belgium: 116 days left

RevisionManager 1.0.1 released
by Philipp von Weitershausen 27 Feb '03

27 Feb '03

Hello everbody, I have released a bugfix release of RevisionManager. RevisionManager is a CVS frontend product for Zope. It brings the power of a great revision control tool to the ZODB. Two bugs were fixed: * Adding adding only binary files raised an exception. * The rather important buttons 'Commit', 'Update' etc. on 'Status' tab were broken. See CHANGES.txt for further information. You may download it at: http://www.zope.org/Members/philikon/RevisionManager RevisionManager is a work in progress and development has not ended with this bugfix release. Help, suggestions and, of course, bugfixes are greatly appreciated! Cheers, Phil

CMF 1.3.1 beta 1 released
by Tres Seaver 26 Feb '03

26 Feb '03

Zope Corporation is pleased to announce the first beta release of version 1.3.1 of the Zope Content Management Framework. This release consists primarily of bug fixes for version 1.3, released in August, 2002. It is a "release candidate"; the final release will follow in a week, presuming no "showstopper" bugs are found. What is the CMF? The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. As packaged, the CMF generates a site much like the Zope.org site. The CMF is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. Where do I get it? Download it from "cmf.zope.org":/download/CMF-1.3.1beta1 . It is available both as a "Windows ZIP file":CMF-1.3.1beta1.zip and as a "Unix tar/gzip archive":CMF-1.3.1beta1.tar.gz . Please read the "release notes":README.txt , the "change history":CHANGES.txt , and the "installation instructions":INSTALL.txt. Where do I go to learn more? The "CMF mailing list":mailto:zope-cmf@zope.org has many participants who are active in supporting the CMF. ...to report bugs? The "CMF Collector":http://collector.zope.org/CMF is ths place to report bugs (please search for existing reports of your issue first!) New Features in 1.3.1beta1 - Implemented PUT and GET support to CMFCalendar.Event for editing via FTP/WebDAV (thanks to Sidnei da Silva). Bug Fixes in 1.3.1beta1 - Fixed incorrect security declaration in File.py (Collector #91). - Remove over-helpful default argument values in 'CMFDefault.DefaultDublinCoreImpl._editMetadata'. Now, if called without a value for an argument, the method will not change that value. Collector #10. - Remove workaround in CMFCore.utils for recognizing links in StructuredText: STX in CMF content should now recognize exactly the same links as the underlying Zope. Note that we *do* still provide a customized HTML class, to permit embedding images without generating the "whole" page. Collector #6. - Remove bizarre, shadowing import of CMFCore.utils as 'utils' into package namespace of CMFDefault; instead, import specific names from that package directly (thanks to Paul Winkler for pointing out the incongruity). - Fix (theoretical) bug in CMFCore.DirectoryView which allowed non-registered directories to slip through (UI didn't exercise it). - Merge Christian Theune's fix for funky default argument values on CMFCalendar.Event's constructor and edit methods (collector #76). - FSPageTemplates overwrote a user-generated 'Content-Type' header. We now check to make sure a Content-Type header is not already set before allowing a page template to set its own. - Fixed bugs around 'addActionProvider' in ActionsTool (Collector #42). - Fixed race condition in lazy initialization of filesystem-based skin methods; the bug led to odd name errors on 'context' for FSPythonScripts (Collector #37). - Removed crufty 'isDesktop' stuff from 'folder_factories' and 'folder_contents' methods. - Fixed HTML-invalidating call to 'filterCookie' in 'folder_contents'. - Fixed unclosed 'tr' element in ZPT version of 'folder_edit_form' (Collector #57). - Fixed CalendarTool to use portal_type and not Type to search for events in the catalog (Collector #28, thanks to Heimo Laukkanen for the report). - Fixed a bug in CalendarTool where events were not showing on the last day of the month.
