by "J. David Ibáñez" 23 Aug '07

23 Aug '07

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.i18n itools.tmx itools.cms itools.ical itools.uri itools.csv itools.odf itools.vfs itools.datatypes itools.pdf itools.web itools.gettext itools.rest itools.workflow itools.handlers itools.rss itools.xhtml itools.html itools.schemas itools.xliff itools.http itools.stl itools.xml This release most important change is the new mechanism to send emails in the CMS. Now the message spool is persistent, messages are written to disk before being sent, this way the system is robust to crash. There is also a simple log to know the emails that have been sent. There is also a bunch of user interface improvements and bug fixes in the CMS, including the Tracker and the Wiki. Credits: - Hervé Cauwelier fixed bugs and refactored code; - J. David Ibáñez implemented the new mail spool; - Henry Obein worked on itools.cms; - Sylvain Taverne worked on itools.cms; Resources --------- Download http://download.ikaaro.org/itools/itools-0.16.7.tar.gz Home http://www.ikaaro.org/itools Mailing list http://mail.ikaaro.org/mailman/listinfo/itools Bug Tracker http://bugs.ikaaro.org/ -- J.

Moving Python's tracker to Roundup on Aug 23rd
by Brett Cannon 21 Aug '07

21 Aug '07

On August 23rd Python will be moving off of SourceForge and over to our own issue tracker run on Roundup (http://bugs.python.org/). During the transition there will be a time where the SourceForge tracker is no longer being used but that the new tracker has not been brought up yet. We expect this gap to be for a few hours. But to minimize issues, please try to avoid using either SourceForge or the new issue tracker on Aug 23rd if you can. -Brett Cannon Chairman, PSF Infrastructure committee

Shed Skin Python-to-C++ compiler 0.0.23
by Mark Dufour 20 Aug '07

20 Aug '07

Hi all, I have just released Shed Skin 0.0.23. It doesn't contain the type inference scalability improvements I was working on, but it does have quite a few bug fixes and minor feature additions. Here's a list of changes: -support for __iadd__, __imul__ and such (except __ipow__ and __imod__) -some overdue set optimizations -fix for string formatting problem (%% did not always work) -extension module stability fixes -fix for particular inheritance problem -other minor bugfixes, cleanups, and error messages I could really use some systematic help in pushing Shedskin further. Some ideas: -send in bug reports - these are extremely valuable and motivating to me, yet I don't receive many.. -find out why test 148 is currently broken under windows -add datetime, re or socket support -look into supporting custom classes in generated extension modules -write a Shedskin tutorial for 'novice' programmers -systemically test performance and suggest and work on improvements -investigate replacements for std::string and __gnu_cxx::hash_set -perform janitorial-type work in ss.py and lib/builtin.?pp -support extension modules under OSX (OSX gives me accute mental RSI) -add more tests to unit.py Thanks, Mark Dufour. -- "One of my most productive days was throwing away 1000 lines of code" - Ken Thompson
