cx_Oracle 4.3.1
by Anthony Tuininga 18 Apr '07

18 Apr '07

What is cx_Oracle? cx_Oracle is a Python extension module that allows access to Oracle and conforms to the Python database API 2.0 specifications with a few exceptions. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Ensure that if the client buffer size exceeds 4000 bytes that the server buffer size does not as strings may only contain 4000 bytes; this allows handling of multibyte character sets on the server as well as the client. 2) Added support for using buffer objects to populate binary data and made the Binary() constructor the buffer type as requested by Ken Mason. 3) Fix potential crash when using full optimization with some compilers. Thanks to Aris Motas for noticing this and providing the initial patch and to Amaury Forgeot d'Arc for providing an even simpler solution. 4) Pass the correct charset form in to the write call in order to support writing to national character set LOB values properly. Thanks to Ian Kelly for noticing this discrepancy. Anthony Tuininga

Release 0.63.1 of Task Coach
by Frank Niessink 16 Apr '07

16 Apr '07

Hi all, I'm pleased to announce release 0.63.1 of Task Coach. This is a bug fix release that should fix the following bugs: * Dropping a file on a task in the tree viewer didn't work. * Showing the description column in the composite effort viewers (effort per day, per week, per month) caused exceptions. * The task tree viewer was trying to update tasks that weren't shown, resulting in exceptions. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://www.taskcoach.org https://sourceforge.net/projects/taskcoach/ In addition to the source distribution, packaged distributions are available for Windows XP, Mac OSX, and Linux (Debian and RPM format). Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

ANN: PyQt v4.2 (Python Bindings for Qt)
by Phil Thompson 16 Apr '07

16 Apr '07

Riverbank Computing is pleased to announce the release of PyQt v4.2 available from http://www.riverbankcomputing.co.uk/pyqt/. The highlights of this release include: - The ability to write widget plugins for Qt Designer in Python. - Integration of the Python command shell and the Qt event loop. This allows developers to call Qt functions dynamically on a running application. - Integration of the Qt event loop with the standard Python DBus bindings available from www.freedesktop.org. PyQt is a comprehensive set of Qt bindings for the Python programming language and supports the same platforms as Qt (Windows, Linux and MacOS/X). Like Qt, PyQt is available under the GPL and a commercial license. See http://www.riverbankcomputing.com/Docs/PyQt4/html/classes.html for the class documentation. PyQt v4 supports Qt v4 (http://www.trolltech.com/products/qt/index.html). PyQt v3 is still available to support earlier versions of Qt. PyQt v4 is implemented as a set of 10 extension modules containing approximately 400 classes and 6,000 functions and methods. QtCore The non-GUI infrastructure including event loops, threads, i18n, Unicode, signals and slots, user and application settings. QtGui A rich collection of GUI widgets. QtNetwork A set of classes to support TCP and UDP socket programming and higher level protocols (eg. HTTP). QtOpenGL A set of classes that allows PyOpenGL to render onto Qt widgets. QtSql A set of classes that implement SQL data models and interfaces to industry standard databases. Includes an implementation of SQLite. QtSvg A set of classes to render SVG files onto Qt widgets. QtTest A set of classes to automate unit testing of PyQt applications and GUIs. QtXML A set of classes that implement DOM and SAX parsers. QtAssistant A set of classes that enables the Qt Assistant online help browser to be integrated with an application. QAxContainer A set of classes for Windows that allows the integration of ActiveX controls and COM objects. A Windows installer is provided for the GPL version of PyQt to be used with the GPL version of Qt v4 (http://www.trolltech.com/download/qt/windows.html). It enabes a complete PyQt environment to be installed on Windows without the need for a C++ compiler. PyQt includes the pyuic utility which generates Python code to implement user interfaces created with Qt Designer in the same way that the uic utility generates C++ code. It is also able to load Designer XML files dynamically.
