Genshi Compiler - Speed up your XML templates
by Ferenczi Viktor 16 Jul '11

16 Jul '11

Genshi Compiler 0.1.1 ===================== I'm pleased to announce the first public release of Genshi Compiler! Project home: http://code.google.com/p/genshi-compiler/ Download here: http://code.google.com/p/genshi-compiler/downloads/ PyPI entry: http://pypi.python.org/pypi/genshi_compiler License: MIT software license Quality: Beta with good unit test coverage Genshi Compiler allows for rendering your Genshi template to Python source code. You can save the code as a Python module or compile it into a directly usable module object in memory. Just call the render function on the module with your template parameters to render the whole template or any of your template functions to render those fragments separately. According to my initial benchmarks the rendering speed is typically ~40x faster than doing the same using Genshi. There is a cost of this speedup, certainly. Some of Genshi's dynamic features are not available, most notably anything that depends on a template loader (xi:include), the XML element tree representation (py:match) or the token stream. If you've read this far, then I guess you want to see the tutorial: http://code.google.com/p/genshi-compiler/wiki/tutorial Regards, Viktor Ferenczi

Pyro 4.8 released
by Irmen de Jong 15 Jul '11

15 Jul '11

Hello, [The first message didn't seem to have come through, So I try posting it again. I'm sorry if you receive this message twice.] Pyro 4.8 has been released! Get it from Pypi: http://pypi.python.org/pypi/Pyro4/ Documentation: http://packages.python.org/Pyro4/ The most important changes in this version: * Major additions to the documentation: tutorials, API docs, and much more. * Unix domain socket support. Added unixdomainsock example. * Fix in name server when dealing with multiple network interfaces. * API change: async callbacks have been changed into a more general "call chain". Pyro = Python Remote Objects. It is a library that enables you to build applications in which objects can talk to each other over the network, with minimal programming effort. You can just use normal Python method calls, with almost every possible parameter and return value type, and Pyro takes care of locating the right object on the right computer to execute the method. It is designed to be very easy to use, and to generally stay out of your way. But it also provides a set of powerful features that enables you to build distributed applications rapidly and effortlessly. Pyro is written in 100% pure Python and therefore runs on many platforms and Python versions, including Python 3.x. Enjoy, Irmen de Jong

roundup 1.4.19 released
by Ralf Schlatterbeck 15 Jul '11

15 Jul '11

I'm proud to release version 1.4.19 of Roundup which introduces some minor features and, as usual, fixes some bugs: Features: - Xapian indexing improved: Slightly faster and slightly smaller database. Closes issue2550687. Thanks to Olly Betts for the patch. (Bernhard Reiter) - PostgreSQL backend minor improvement: database creation less likely to fail for PostgreSQL versions >= 8.1 as the table "postgres" is used by default. Closes issue2550543. Thanks to Kai Storbeck for the patch. (Bernhard Reiter) - Allow HTMLRequest.batch to filter on other permissions than "View" (e.g. on the new "Search" permission") by adding a "permission" parameter. Thanks to Eli Collins for the patch. Closes issue2550699. (Ralf) Fixed: - Installation: Fixed an issue that prevented to use EasyInstall and a Python egg. Thanks to Satchidanand Haridas for the patch and John Kristensen for testing it. (Bernhard Reiter) - The PostgreSQL backend quotes database names now for CREATE and DROP, enabling more exotic tracker names. Closes issue2550497. Thanks to Sebastian Harl for providing the patch. (Bernhard Reiter) - Updated the url to point to www.roundup-tracker.org in two places in the docs. (Bernhard Reiter) - Do not depend on a CPython implementation detail anymore to make Roundup more compatible with other Python implementations like PyPy. Closes issue2550707. Thanks to Christof Meerwald. (Bernhard Reiter, Richard) - Yet another fix to the mail gateway, messages got *all* files of an issue, not just the new ones. Thanks to Rafal Bisingier for reporting and proposing a fix. The regression test was updated. (Ralf) - Fix version numbers in upgrade documentation, the file-unlink defect was in 1.4.17 not 1.4.16. Thanks to Rafal Bisingier. (Ralf) - Fix encoded email header parsing if multiple encoded and non-encoded parts are present. RFC2047 specifies that spacing is removed only between encoded parts, we always removed the space. Note that this bug was present before mail gateway refactoring :-) Thanks for thorough testing of mail gateway code by Rafal Bisingier. (Ralf) - The "Retire" permission was not being registered. (Richard) - Fix StringIO issue2550713: io.StringIO in newer versions of python returns unicode strings and expects a unicode string in the constructor. Unfortunately csv doesn't handle unicode (yet). So we need to use a BytesIO which gets the utf-8 string from the web-interface. Compatibility for old versions by using StringIO.StringIO for emulating a io.BytesIO also works. Thanks to Cedric Krier for reporting. Closes issue2550713. Added a regression test for EditCSVAction (Ralf) - Fix issue2550691 where a Unix From-Header was sometimes inserted in outgoing emails, thanks to Joseph Myers for the patch. (Ralf) If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.4 or later (but not 3+) for correct operation. To give Roundup a try, just download (see below), unpack and run:: roundup-demo Release info and download page: http://cheeseshop.python.org/pypi/roundup Source and documentation is available at the website: http://roundup-tracker.org/ Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.4+ (but not 3+) installation. It doesn't even need to be "installed" to be operational, though an install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and four database back-ends (anydbm, sqlite, mysql and postgresql). -- Dr. Ralf Schlatterbeck Tel: +43/2243/26465-16 Open Source Consulting www: http://www.runtux.com Reichergasse 131, A-3411 Weidling email: office(a)runtux.com osAlliance member email: rsc(a)osalliance.com

[ANN] Bento 0.0.6, a packaging solution for python software
by David Cournapeau 15 Jul '11

15 Jul '11

Hi, I am pleased to announce a new release of bento, a packaging solution for python which aims at reproducibility, extensibility and simplicity. It supports every python version from 2.4 to 3.2. You can take a look at its main features on Bento's main page (http://cournape.github.com/Bento). The main features of this 0.0.6 release are: - Completely revamped distutils compatibility layer: it is now a thin layer around bento infrastructure, so that most bento packages should be pip-installable, while still keeping bento customization capabilities. - Build directory is now customizable through bentomaker with --build-directory option - Out of tree builds support (i.e. running bento in a directory which does not contain bento.info), with global --bento-info option - Hook File can now be specified in recursed bento.info - Preliminary support for .mpkg (Mac OS X native packaging) - More consistent API for extension/compiled library build registration - Both numpy and scipy can now be built with bento + waf as a build backend Bento is discussed on the bento mailing list (http://librelist.com/browser/bento). cheers, David

[ANN] TurboGears 1.5 released
by Christoph Zwerschke 14 Jul '11

14 Jul '11

On behalf of the TurboGears Team, I am pleased to announce that TurboGears 1.5 is now available for download at http://www.turbogears.org and the Python package index http://pypi.python.org/pypi/TurboGears Instructions for downloading and installing are at http://www.turbogears.org/1.5/docs/Install.html Changelog and upgrade instructions are available via http://www.turbogears.org/1.5/docs/WhatsNew.html Note that the well-known TurboGears 1 documentation has been cleaned up and migrated from MoinMoin to Sphinx. TurboGears 1 is a web-framework that has been created by Kevin Dangoor in 2005. Version 1.5 is the latest version in the original TurboGears 1 branch based on CherryPy, now featuring CherryPy 3. Simultaneously, we have also released bugfix versions 1.0.10 and 1.1.3 of the older branches running on CherryPy 2. The 1.0 branch is suitable for Python 2.3 to 2.5, while the 1.1 and 1.5 branches support Python 2.4 to 2.7. We recommend upgrading older TurboGears 1.x versions to 1.5 which is usually much easier than upgrading to 2.x. New TurboGears projects should start with TurboGears 2 which is the current, actively maintained variant of the TurboGears web-framework, based on Pylons instead of CherryPy. Have fun with TurboGears and let us know on the mailing list if there are any problems. -- Christoph Zwerschke
