SPyRE version 0.5 -> Simple Pythonic Rendering Engine
by dvkeeney＠gmail.com 26 Oct '04

26 Oct '04

The "Pitcher's Duel" project has released SPyRE v0.5 (Simple Pythonic Rendering Engine), a conversion of the lightweight rendering engine 'zoe', to use Pygame/SDL rather than GLUT. This release also includes html help files. SPyRE was formerly known as zoePG. Provide pyOpenGL code to draw the model, and the SPyRE engine will display the model in an interface that provides zooming, panning and rotation of camera position using mouse and keyboard. The project includes demos such as a fountain of sparks, a swarming behavior model, a random walk example, a whirlpool effect using gravity and drag, and an example of chaos theory, and a lighted shaded forest scene. The project page is at http://pduel.sourceforge.net/spyre To use SPyRE, you also need to have installed Python, pyOpenGL, and PyGame. David Keeney

ZODB 3.2.4 (final) released
by Tim Peters 25 Oct '04

25 Oct '04

I'm pleased to announce the release of ZODB 3.2.4 (final). This corresponds to the ZODB (and ZEO) that shipped with Zope 2.7.3 (final). You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.2 Note that 3.2.4 incorporates a major change in semantics: it's incorrect to attempt to close a connection when objects from that connection are still in a modified state, and 3.2.4 raises the new ConnectionStateError exception in such cases. 3.2.4 also incorporates a significant ZEO performance fix, and a number of smaller bugfixes. See the news file for details: http://zope.org/Products/ZODB3.2/NEWS Note that ZODB 3.2.4 does not support Zope 2.7.2, because the Zope 2.7.2 publishing subsystem is an example of application code that didn't always finish a transaction before closing connections. ZODB 3.2.4 can be used with Zope 2.7.3. Note that ZODB 3.2.4 does not support Zope X3 or Zope 2.8 (they require ZODB 3.3).

[ANN] PyLint 0.5
by Sylvain Thénault 25 Oct '04

25 Oct '04

Hi all, I'm pleased to announce a new PyLint's release. This is a major development release, since PyLint doesn't have anymore to import analyzed modules (well, there are still some cases where modules are imported, but it's not to build the underlying representation of the python source code). This release requires the latest common library release (0.7). Visit our website to download it or to get more information : http//www.logilab.org/projects/pylint Enjoy ! -- Sylvain Thénault LOGILAB, Paris (France). http://www.logilab.com http://www.logilab.fr http://www.logilab.org

py2exe 0.5.4 released
by Thomas Heller 22 Oct '04

22 Oct '04

**py2exe 0.5.4** released =================================== py2exe is a Python distutils extension which converts python scripts into executable windows programs, able to run without requiring a python installation. Console and Windows (GUI) applications, windows NT services, exe and dll COM servers are supported. Changes in this release: * The new ``--xref`` or ``-x`` command line switch instructs py2exe to create a python module cross reference and display it in the webbrowser. This allows to answer question why a certain module has been included, or if you can exlude a certain module and it's dependencies. This has *not* been extensively tested, but it's a start. Also, the html page includes links which will even allow to view the source code of a module in the browser, for easy inspection. A sample cross reference can be found here, note that the links to open the .py files will of course not work over the internet: http://starship.python.net/crew/theller/py2exe/sample_xref.html * Mark Hammond fixed some thread state issues with dll com servers. * Mark Hammond added support for standalone ISAPI dlls. * py2exe now can handle python modules with the '.pyw' extension. * It is now allowed to specify 'zipfile=None' in the setup script, in this case the zip archive containing the python modules will be appended to the exe file. Homepage: <http://starship.python.net/crew/theller/py2exe> Download from the usual location: <http://sourceforge.net/project/showfiles.php?group_id=15583> Enjoy, Thomas

ANN: Candygram 1.0 final released. (Python + Erlang)
by mike＠hobbshouse.org 21 Oct '04

21 Oct '04

Announcing the final release of Candygram 1.0. There are no changes from the beta 2 release. Candygram is a Python implementation of Erlang concurrency primitives. Erlang is widely respected for its elegant built-in facilities for concurrent programming. This package attempts to emulate those facilities as closely as possible in Python. With Candygram, developers can send and receive messages between threads using semantics nearly identical to those in the Erlang language. More information about Candygram can be found at http://candygram.sourceforge.net
