Zope X3 3.0.0 beta 3 released
by Stephan Richter 15 Aug '04

15 Aug '04

The Zope 3 development team is proud to announce the third beta release of Zope X3 3.0.0. Zope X3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. The "X" in the name stands for "experimental", since this release does not try to provide any backward-compatibility to Zope 2. Downloads http://zope.org/Products/ZopeX3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt of the distribution. The binary installer is recommended for Windows. Changes since beta 2 - Updated to use ZODB 3.3b2. - Reviewed security and fixed many outstanding open issues. This required some rearranging and writing of security-related code. - Removed several uses of 'removeAllProxies()' as this is considered a bad coding practice. - Added 'zope.security.proxy.removeSecurityProxy()' function to replace 'zope.security.proxy.trustedRemoveSecurityProxy()'. - Implemented rdb:gadflyRoot directive. You are now able to specifically point to a directory that should contain the gadfly databases. - When browsing the source code via the API doc tool's Class Browser, ZCML files are now shown as well. When viewed, a marked up version of the ZCML code is shown with links to other parts of the documentation. - Resolved or otherwise dealt with issues 112, 122, 130, 133, 139, 162, 190, 194, 202, 203, 211, 212, 219, 220, 221, 225, 228, 231, 234, 235, 238, 239, 245, 247, 249, 251, 252, 253, 255. - Fixed various bugs in the API doc tool. - Factory IDs have to be real IDs now, i.e. either a dotted name or a URI. - Cleaned up much of the source code. Now every module should have a module doc string with a title and 'id' tag in it. Goals The API is frozen for X3.0.0. We would like to ask all people to test this release and report any bugs or mis-behaviors! This might be the last beta release! The entire beta period will likely last for about 2 months. During this time we will try to complete the following tasks: - Fix outstanding bugs. - Optimize critical components to speed up the system. - Write and update documentation. - Add and complete translations. - Remove as many XXX comments as possible. Though much progress has been made since the second beta, there are still tasks to be completed! Even if you are not a programmer, you can help! Please send any bug reports and comments to zope3-dev(a)zope.org! Thank you very much in advance for your help! Contributors Jim Fulton, Fred Drake, Dmitry Vasiliev, Philipp von Weitershausen, Stephan Richter, Garrett Smith, Tim Peters. Thanks to everyone!

ANN: wxPython 2.5.2.7
by Robin Dunn 14 Aug '04

14 Aug '04

Announcing ---------- I'm pleased to announce the 2.5.2.7 release of wxPython, now available for download at http://wxpython.org/download.php or https://sourceforge.net/project/showfiles.php?group_id=10718&package_id=105… What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the popular wxWidgets cross platform GUI library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit Microsoft Windows, most Linux or other Unix-like systems using GTK or GTK2, and Apple Macintosh OS X. Changes in 2.5.2.7 ------------------ The changes in this version are too numerous to list here, please see the following web sites for more details. If you are upgrading from a previous version then please do read the MigrationGuide fully before getting started as there are some backwards incompatible changes. http://wxpython.org/recentchanges.php http://wxpython.org/migrationguide.php New Docs -------- Also available with this release is a sneak peak at the work in progress for the new Python-specific reference documentation. While much of the content is not yet present, the docs are still usable, and in fact helpful since they already accurately document what classes and methods are present in wxPython and what the parameter names are. You can download a tarball containing the new docs by following the wxPythonNewDocs link on the download page, and it can also be accessed online at http://wxPython.org/docs/api/. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!

[ANN] pyOpenSSL 0.6 released
by Martin Sjögren 13 Aug '04

13 Aug '04

After a long hiatus during which I've somehow managed to write a master's thesis, I'm pleased to announce the release of pyOpenSSL 0.6. There are bug fixes, the most important being support for the cyclic GC, which got rid of a few nasty memory leak bugs. There is added functionality to some types, there is brand new support for the Netscape SPKI extensions and much more. Much of this comes from contributions from the user base and I'm really happy about that. If anybody would like to contribute Windows binaries, I'd be happy to put them on the sourceforge project page, I have no possibility to compile them myself. Grab the release from http://sourceforge.net/project/showfiles.php?group_id=31249&package_id=2329… /Martin Sjögren

[ANN] WebFormKit 0.1 released.
by Antonio Cuni 11 Aug '04

11 Aug '04

WebFormKit is a Webware's plugin that helps programmers to develop Web based application. One of the key concept of WebFormKit is the strong separation between presentation logic and business logic: a page is generally composed by an XML file containing the structure of the document and a Python file, containing the programming logic underlying the page. It is event-driven, meaning that developing WebFormKit's application is in a way similar to developing "standard" GUI application. Finally, WebFormKit is very extensible: developers can easly write their own custom extensions that will fit perfectly in core APIs. You can download WebFormKit from http://webformkit.sourceforge.net

ANN: Leo 4.2 beta 3 now available
by Edward K. Ream 11 Aug '04

11 Aug '04

Leo 4.2 Beta 3 is now available at http://sourceforge.net/projects/leo/ This version of Leo is feature complete. Leo's core code has been stable for several months. To do: most plugins work with the new code base, but other plugins need some more work. Late note: the *nix install script will work better with *nix line endings :-) The highlights of Leo 4.2: - @thin trees make Leo much more friendly to cvs. - Leo's data structures have been reorganized to make outline operations significantly faster. All old script still work. - @test and @script nodes convert scripts to unit tests automatically. Converting scripts to unit tests now takes a few seconds! - A faster and more robust spell checker plugin. (requires Python 2.3) - Leo is now much more friendly to using spaces instead of tabs. - The Execute Script command reports erroneous lines more clearly. - The Perfect Import feature guarantee that Leo imports file exactly. - Leo draws large outlines more quickly with less memory used. - Dozens of other improvements. Quotes of the month ------------------- "I'm a newbie to Leo(a couple of weeks) and I feel addicted to programming again...in fact it has resurrected a dead project of mine :) The outline has proven most liberating in terms of testing ideas out. Thanks a lot!" -- anon "Wow, wow, and wow. I just started using Leo about a month ago..Now I finally understand how to use clones and I realized that this is exactly how I want to organize my information. Multiple views on my data, fully interlinkable just like my thoughts...Thanks for a great tool! -- anon "I *LIKE* it; I was amazed at how [different the Leo] experience was compared to flat-filing. It was almost Forth-like in the way that it was possible to work top-down or bottom-up at will (I believe this is the key to its strength, btw)." --Tarvin Rhodes What is Leo? ------------ - A programmer's editor, an outlining editor and a flexible browser. - A literate programming tool, compatible with noweb and CWEB. - A data organizer and project manager. Leo provides multiple views of projects within a single outline. - Fully scriptable using Python. Leo saves its files in XML format. - Portable. leo.py is 100% pure Python. - Open Software, distributed under the Python License. Leo requires Python 2.2.1 or above and tcl/tk 8.4 or above. Leo works on Linux, Windows and MacOs X.

Outcome of third Bug Day
by A.M. Kuchling 09 Aug '04

09 Aug '04

The Python Bug Day held this past Saturday went well. 19 bugs and 12 patches were closed. That's not as good as the first bug day (30 bugs), but is competitive with the second (18 bugs, 21 patches). Lots of the easy bugs have been cleaned out, I expect, so each remaining bug takes more time to fix. Sadly, while a request on python-dev earlier in the week resulted in much higher participation by people with CVS commit privileges, there weren't as many non-committer people around as on the previous bug days. During the course of the day, Armin Rigo wrote a nifty IRC bot that takes an SF bug/patch ID and returns the title; taking an example from the transcript: 20:53:56 <jlgijsbers> Looking at #777659. 20:53:57 <sf_number> * sf_number bug 777659 - Uninitialized variable used in Tools/faqwiz/faqwiz.py I won't be running a bug day in September; if someone else wants to arrange it, please feel free. Otherwise, the next bug day will probably be in October; watch comp.lang.python.announce for an annoucement in early October. --amk
