PyCon Dress Rehearsal at the Greater Toronto Area Python User's Group, Feb 16th, 7pm
by Mike C. Fletcher Feb. 9, 2010

Feb. 9, 2010

This month at PyGTA we have a special treat, 3 PyCon Presenters will do a dress rehearsal of their PyCon 2010 presentations just before they head down to Atlanta. All three talks are targeting general audiences, so feel free to bring along your new Pythonista friends. We have 3 PyCon previews scheduled: * What We've Learned From Building Basie — Greg Wilson * Think Globally, Hack Locally - Teaching Python in Your Community — Leigh Honeywell * Debating 'til Dawn: Topics to keep you up all night — Mike Fletcher We will give each presenter 20 minutes and then as much question/answer and feedback time as they want. At PyCon they'll only get 30 minutes total, but we want to give them as much feedback as possible so they can polish their presentation for the larger audience. We'll start the presentations at 7:30PM (sharp) at Linux Caffe on the 16th. If you bring a laptop, there will be an immediate feedback channel available. PyGTA: http://www.pygta.org Linux Caffe: http://www.pygta.org/venue/ Have fun, Mike -- ________________________________________________ Mike C.

Roundup Issue Tracker 1.4.12 released
by Richard Jones Feb. 9, 2010

Feb. 9, 2010

I'm proud to release version 1.4.12 of Roundup which fixes a number bugs. This release includes fixes for some potential security holes. Please see the upgrading documentation for details of what you might need to do in your tracker. If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. This release includes: - Support IMAP CRAM-MD5, thanks Jochen Maes - Proper handling of 'Create' permissions in both mail gateway (earlier commit r4405 by Richard), web interface, and xmlrpc. This used to check 'Edit' permission previously. See http://thread.gmane.org/gmane.comp.bug-tracking.roundup.devel/5133 Add regression tests for proper handling of 'Create' and 'Edit' permissions. - Fix handling of non-ascii in realname in the nosy mailer, this used to mangle the email address making it unusable when replying. Thanks to intevation for funding the fix. - Fix documentation on user required to run the tests, fixes issue2550618, thanks to Chris aka 'radioking' - Add simple doc about translating customised tracker content - Add "flup" setup documentation, thanks Christian Glass - Fix "Web Access" permission check to allow serving of static files to Anonymous again - Add check for "Web Access" permission in all web templating permission checks - Improvements in upgrading documentation, thanks Christian Glass - Display 'today' in the account user's timezone, thanks David Wolever - Fix file handle leak in some web interfaces with logging turned on, fixes issue1675845 - Attempt to generate more human-readable addresses in email, fixes issue2550632 - Allow value to be specified to multilink form element templating, fixes issue2550613, thanks David Wolever - Fix thread safety with stdin in roundup-server, fixes issue2550596 (thanks Werner Hunger) Roundup requires python 2.3 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.sourceforge.net/ 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 2.3+ (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).

pylib/py.test 1.2.1 released: improvements, fixes
by holger krekel Feb. 8, 2010

Feb. 8, 2010

py.test is a mature, advanced automated testing tool working with Python2, Python3 and Jython versions on all major operating systems. It has a simple plugin architecture and can run many existing common Python test suites without modification. It offers some unique features not found in other testing tools. See http://pytest.org for more info. py.test 1.2.1 brings bug fixes and some new options and abilities triggered by user feedback: * --funcargs [testpath] will show available builtin- and project funcargs. * display a short and concise traceback if funcarg lookup fails. * early-load "conftest.py" files in non-dot first-level sub directories. * --tb=line will print a single line for each failing test (issue67) * py.cleanup has a number of new options, cleanups up setup.py related files * fix issue78: always call python-level teardown functions even if the according setup failed. For more detailed information see http://codespeak.net/py/dist/announce/release-1.2.1.html or the CHANGELOG below. cheers and have fun, holger Changes between 1.2.1 and 1.2.0 ===================================== - refined usage and options for "py.cleanup":: py.cleanup # remove "*.pyc" and "*$py.class" (jython) files py.cleanup -e .swp -e .cache # also remove files with these extensions py.cleanup -s # remove "build" and "dist" directory next to setup.py files py.cleanup -d # also remove empty directories py.cleanup -a # synonym for "-s -d -e 'pip-log.txt'" py.cleanup -n # dry run, only show what would be removed - add a new option "py.test --funcargs" which shows available funcargs and their help strings (docstrings on their respective factory function) for a given test path - display a short and concise traceback if a funcarg lookup fails - early-load "conftest.py" files in non-dot first-level sub directories. allows to conveniently keep and access test-related options in a ``test`` subdir and still add command line options. - fix issue67: new super-short traceback-printing option: "--tb=line" will print a single line for each failing (python) test indicating its filename, lineno and the failure value - fix issue78: always call python-level teardown functions even if the according setup failed. This includes refinements for calling setup_module/class functions which will now only be called once instead of the previous behaviour where they'd be called multiple times if they raise an exception (including a Skipped exception). Any exception will be re-corded and associated with all tests in the according module/class scope. - fix issue63: assume <40 columns to be a bogus terminal width, default to 80 - fix pdb debugging to be in the correct frame on raises-related errors - update apipkg.py to fix an issue where recursive imports might unnecessarily break importing - fix plugin links

ANN: PyBindGen 0.14
by Gustavo Carneiro Feb. 7, 2010

Feb. 7, 2010

PyBindGen is a Python module that is geared to generating C/C++ code that binds a C/C++ library for Python. It does so without extensive use of either C++ templates or C pre-processor macros. It has modular handling of C/C++ types, and can be easily extended with Python plugins. The generated code is almost as clean as what a human programmer would write. It can be downloaded from: http://code.google.com/p/pybindgen/ Bug reports should be filed here: https://bugs.launchpad.net/ <https://bugs.launchpad.net/pybindgen> pybindgen <https://bugs.launchpad.net/pybindgen> <https://bugs.launchpad.net/pybindgen>Documentation: http://packages.python.org/PyBindGen/ NEWS: === pybindgen 0.14 === - Multiple inheritance support - Virtual methods can now be overridden with Method instead of _Method - Add annotation support for instance attributes - Benchmarks (vs Boost.Python, SWIG, and SIP) - New types supported: int16_t& and std::string* parameter types - Non-virtual protected methods are now also wrapped - Wrap enum pointer params Note: this release marks the beginning of a transition to a minor change in the API of the generated bindings. Prior to PyBindGen version 0.14, the code generated to handle C++ virtual methods required Python user code to define a _foo method in order to implement the virtual method foo. Since 0.14, PyBindGen changed so that virtual method foo is implemented in Python by defining a method foo, i.e. no underscore prefix is needed anymore. Setting pybindgen.settings.deprecated_virtuals to True will force the old virtual method behaviour. But this is really deprecated; newer code should set pybindgen.settings.deprecated_virtuals to False. In PyBindGen 0.14, if the option pybindgen.settings.deprecated_virtuals is not set, PyBindGen emits a warning and assumes the value of True in order to preserve backward compatibility. In PyBindGen 0.15, the default value of this option will change to False, and in 0.16 the support for deprecated virtuals will be removed. This change was made to make the user code interface more intuitive, and to align it with other Python bindings tools such as SIP, Boost.Python, and SWIG. -- Gustavo J. A. M.

execnet-1.0.5 released: doc & finalization fixes
by holger krekel Feb. 7, 2010

Feb. 7, 2010

execnet is a small and stable pure-python library for working with local or remote clusters of Python interpreters, with ease. It supports seamless instantiation of and interaction with remote interpreters through the 'ssh' command line tool. It supports Python 2.4-3.1, Jython-2.5.1 and pypy-c. The 1.0.5 release is a minor backward compatible release with these changes: - more care during receiver-thread finalization during interp-shutdown, should get rid of annoying and meaningless exceptions - fix glitch in ssh-fileserver example - experimentally add "setup.py test" support - will run py.test More info here: http://codespeak.net/execnet cheers, holger --

[RELEASED] Python 2.7 alpha 3
by Benjamin Peterson Feb. 6, 2010

Feb. 6, 2010

On behalf of the Python development team, I'm cheerful to announce the third alpha release of Python 2.7. Python 2.7 is scheduled (by Guido and Python-dev) to be the last major version in the 2.x series. Though more major releases have not been absolutely ruled out, it's likely that the 2.7 release will an extended period of maintenance for the 2.x series. 2.7 includes many features that were first released in Python 3.1. The faster io module, the new nested with statement syntax, improved float repr, set literals, dictionary views, and the memoryview object have been backported from 3.1. Other features include an ordered dictionary implementation, unittests improvements, a new sysconfig module, and support for ttk Tile in Tkinter. For a more extensive list of changes in 2.7, see http://doc.python.org/dev/whatsnew/2.7.html or Misc/NEWS in the Python distribution. To download Python 2.7 visit: http://www.python.org/download/releases/2.7/ Please note that this is a development release, intended as a preview of new features for the community, and is thus not suitable for production use. The 2.7 documentation can be found at: http://docs.python.org/2.7 Please consider trying Python 2.7 with your code and reporting any bugs you may notice to: http://bugs.python.org Enjoy! -- Benjamin Peterson 2.7 Release Manager benjamin at python.org (on behalf of the entire python-dev team and 2.7's contributors)
