Hello! I'm pleased to announce version 0.14.0, the first stable release of branch 0.14 of SQLObject. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://pypi.python.org/pypi/SQLObject/0.14.0 News and changes: http://sqlobject.org/News.html What's New ========== News since 0.13 --------------- Features & Interface ~~~~~~~~~~~~~~~~~~~~ * The lists of columns/indices/joins are now sorted according to the order of declaration. * ``validator2`` was added to all columns; it is inserted at the beginning of the list of validators, i.e. its ``from_python()`` method is called first, ``to_python()`` is called last, after all validators in the list. * SQLiteConnection's parameter ``use_table_info`` became boolean with default value True; this means the default schema parser is now based on ``PRAGMA table_info()``. * Major API change: attribute 'dirty' was moved to sqlmeta. For a more complete list, please see the news: http://sqlobject.org/News.html Oleg. -- Oleg Broytman http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

[ANN] bento 0.0.4, a pythonic packaging solution for python softwares
by David Cournapeau 10 Oct '10

10 Oct '10

Hi, I am pleased to announce the release 0.0.4 for Bento, a pythonic packaging solution for python softwares. Bento is an alternative to distutils/setuptools/distutils2 geared toward simplicity and hackability: http://cournape.github.com/Bento/ Download: http://github.com/cournape/Bento/archives/master Documentation: http://cournape.github.com/Bento/html This release is a significant milestone, as it is able to build two complex packages (numpy and scipy). The main new features are: - New hooks to modify, override compilation options on a per extension basis (e.g. build one extension with optimized flags and another one without). - Recursive package description support to split big packages descriptions into several files - Option to generate a python module containing all install paths, to avoid using __file__ without depending on complex tools ala, pkb_resources. - Improved documentation - Some work toward python 3 support (does not work yet for complex packages) cheers, David

[Ann] Celery 2.1 stable released
by Ask Solem 08 Oct '10

08 Oct '10

Hey! Celery 2.1.0 was just uploaded to PyPI! This is a backward compatible release in the 2.x series, and is an recommended upgrade for all users. What is Celery? ============ Celery is an open source asynchronous task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well. The execution units, called tasks, are executed concurrently on one or more worker nodes. Tasks can execute asynchronously (in the background) or synchronously (wait until ready). For more information go to http://celeryproject.org Highlights ======== * Periodic task schedule can now be stored in a database, and changes will be reflected at runtime (only supported by django-celery at the moment, but this can also be used in general) http://celeryq.org/docs/userguide/periodic-tasks.html#periodic-tasks * New web monitor using the Django Admin interface. Can also be used by non-Django users. http://celeryq.org/docs/userguide/monitoring.html#django-admin-monitor * Periodic tasks now supports arguments and keyword arguments. * celeryctl: A new command line utility to inspect and manage worker nodes. http://celeryq.org/docs/userguide/monitoring.html#celeryctl-management-util… * AMQP Backend: Now supports automatic expiration of results. * Task expiration: A date and time which after the task will be considered expired and will not be executed. * Lots of bugs fixed. * Lots of documentation improvements. Changes ======= The full list of changes are available in the changelogs: * celery: http://celeryq.org/docs/changelog.html * django-celery: http://celeryq.org/docs/django-celery/changelog.html Download ======== * celery: http://pypi.python.org/pypi/celery/2.1.0 * django-celery: http://pypi.python.org/pypi/django-celery/2.1.0 -- {Ask Solem, +47 98435213 | twitter.com/asksol }.

ANN: Roundup Issue Tracker 1.4.16 released
by Richard Jones 08 Oct '10

08 Oct '10

I'm proud to release version 1.4.16 of Roundup which introduces some minor features and, as usual, fixes some bugs: Features: - allow trackers to override the classes used to render properties in templating per issue2550659 (thanks Ezio Melotti) - new mailgw configuration item "subject_updates_title": If set to "no" a changed subject in a reply to an issue will not update the issue title with the changed subject. Thanks to Arkadiusz Kita and Peter Funk for requesting the feature and discussing the implementation. http://thread.gmane.org/gmane.comp.bug-tracking.roundup.user/10169 - new rdbms config item sqlite_timeout makes the previously hard-coded timeout of 30 seconds configurable. This is the time a client waits for the locked database to become free before giving up. Used only for SQLite backend. - new mailgw config item unpack_rfc822 that unpacks message attachments of type message/rfc822 and attaches the individual parts instead of attaching the whole message/rfc822 attachment to the roundup issue. Fixed: - fixed reporting of source missing warnings - relevant tests made locale independent, issue2550660 (thanks Benni Bärmann for reporting). - fix for incorrect except: syntax, issue2550661 (thanks Jakub Wilk) - No longer use the root logger, use a logger with prefix "roundup", see http://thread.gmane.org/gmane.comp.bug-tracking.roundup.devel/5356 - improve handling of '>' when URLs are converted to links, issue2550664 (thanks Ezio Melotti) - fixed registration, issue2550665 (thanks Timo Paulssen) - make sorting of multilinks in the web interface more robust, issue2550663 - Fix charset of first text-part of outgoing multipart messages, thanks Dirk Geschke for reporting, see http://thread.gmane.org/gmane.comp.bug-tracking.roundup.user/10223 - Fix handling of incoming message/rfc822 attachments. These resulted in a weird mail usage error because the email module threw a TypeError which roundup interprets as a Reject exception. Fixes issue2550667. Added regression tests for message/rfc822 attachments with and without configured unpacking (mailgw unpack_rfc822, see Features above) Thanks to Benni Bärmann for reporting. - Allow search_popup macro to work with all db classes, issue2550567 (thanks John Kristensen) - lower memory footprint for (journal-) import 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 2.3 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).

Evolutionary Algorithms in Python (EAP) First Public Release (0.6)
by Félix-Antoine Fortin 08 Oct '10

08 Oct '10

Hi everyone, We are proud to announce the first public release of EAP, a library for doing Evolutionary Algorithms in Python. You can download a copy of this open source project at the following web page. http://deap.googlecode.com EAP has been built using the Python and UNIX programming philosophies in order to provide a transparent, simple and coherent environment for implementing your favourite evolutionary algorithms. EAP is very easy to use even for those who do not know much about the Python programming language. EAP uses the object oriented paradigm that is provided by Python in order to make development simple and beautiful. It also contains a 15 illustrative and diversified examples, to help newcomers to ramp up very quickly in using this environment. EAP is part of the DEAP project, that also includes some facilities for the automatic distribution and parallelization of tasks over a cluster of computers. The D part of DEAP, called DTM, is under intense development and currently available as an alpha version. DTM currently provides two and a half ways to distribute workload on a cluster or LAN of workstations, based on MPI and TCP communication managers. This public release (version 0.6) is more complete and simpler than ever. It includes Genetic Algorithms using any imaginable representation, Genetic Programming with strongly and loosely typed trees in addition to automatically defined functions, Evolution Strategies (including Covariance Matrix Adaptation), multiobjective optimization techniques (NSGA-II and SPEA2), easy parallelization of algorithms and much more like milestones, genealogy, etc. We are impatient to hear your feedback and comments on that system at <deap-users at googlegroups dot com> Best, François-Michel De Rainville Félix-Antoine Fortin Marc-André Gardner Christian Gagné Marc Parizeau Laboratoire de Vision et Systèmes Numériques Département de génie électrique et génie informatique Université Laval Quebec City (Quebec), Canada
