RELEASE: Elisa 0.3.1 'Reborn'
by Philippe Normand Aug. 3, 2007

Aug. 3, 2007

The Elisa team is proud to announce the release of Elisa 0.3.1 'Reborn' which ends a 6 months rework of the codebase. Elisa is an open source cross-platform media center solution designed to be simple for people not particularly familiar with computers. With Elisa you can enjoy your photos, movies, music and online services from the comfort of your living room. This new version is an exciting one for us since it represents an important step towards the main goals of Elisa: - simplicity of use, intuitivity and prettiness of the user interface. - very shallow learning curve to extend Elisa through a new plugins system. - on the universality side, we are also pleased to have a MacOS/X port working; a Windows port will be available before the end of the year. You will find a screencast and screenshots of this new version on http://elisa.fluendo.com/screenshots Tarballs are up at http://elisa.fluendo.com/download For more information, see http://elisa.fluendo.com To file bugs, go to https://core.fluendo.com/elisa/trac/newticket?component=core Philippe Normand, on behalf of the Elisa development team

cx_Oracle 4.3.2
by Anthony Tuininga Aug. 3, 2007

Aug. 3, 2007

What is cx_Oracle? cx_Oracle is a Python extension module that allows access to Oracle and conforms to the Python database API 2.0 specifications with a few exceptions. Where do I get it? http://cx-oracle.sourceforge.net NOTE: I have changed providers. Please update any links. What's new? 1) Added methods open(), close(), isopen() and getchunksize() in order to improve performance of reading/writing LOB values in chunks. 2) Fixed support for native doubles and floats in Oracle 10g; added new type NATIVE_FLOAT to allow specification of a variable of that specific type where desired. Thanks to D.R. Boxhoorn for pointing out the fact that this was not working properly when the arraysize was anything other than 1. 3) When calling connection.begin(), only create a new tranasction handle if one is not already associated with the connection. Thanks to Andreas Mock for discovering this and for Amaury Forgeot d'Arc for diagnosing the problem and pointing the way to a solution. 4) Added attribute cursor.rowfactory which allows a method to be called for each row that is returned; this is about 20% faster than calling the method in Python using the idiom [method(*r) for r in cursor]. 5) Attempt to locate an Oracle installation by looking at the PATH if the environment variable ORACLE_HOME is not set; this is of primary use on Windows where this variable should not normally be set. 6) Added support for autocommit mode as requested by Ian Kelly. 7) Added support for connection.stmtcachesize which allows for both reading and writing the size of the statement cache size. This parameter can make a huge difference with the length of time taken to prepare statements. Added support for setting the statement tag when preparing a statement. Both of these were requested by Bjorn Sandberg who also provided an initial patch. 8) When copying the value of a variable, copy the return code as well. Anthony Tuininga

Job Fair F/OSS project
by emperorcezar＠gmail.com Aug. 3, 2007

Aug. 3, 2007

Hello Pythonistas! I'm looking for some volunteers for a new open source project. At the Institute of Design (http://www.id.iit.edu ), our next project is a system for the management of our job fair (http://www.id.iit.edu/ recruitID/ ) The systems goal is to allow students and employers to enter their availability for interviews and have the system designate times and rooms for each to meet for interviews. The system includes much more than just this of course, but that is the main goal. We decided that this application is generic enough that it should be made into an F/ OSS project. So far the system will be built on Django and uses (hopefully) Prototype.js The project is on the ground floor and some basic wire frames and a few other preliminary designs. I'm personally located in Chicago and West Virginia (about half of my time spent in each place), though you are welcome to help out from anywhere around the world! If you're interested, reply to this message, or contact me at cezar AT id.iit.edu

itools 0.16.5 released
by "J. David Ibáñez" Aug. 2, 2007

Aug. 2, 2007

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 For compatibility with Windows, all scripts have been renamed to have the extension ".py" (remember to clean the old ones from your install). Also, "igettext-extract.py" works now with Windows Python files. We have a new script called "isetup-copyright.py", it has been created to help us to keep track of who did what and when in the code (to do so it uses the "git blame" command). This is the first step in a long process to audit the code for ownership. The "setup.conf" file supports two new variables: "source_language" and "target_languages". The first one allows to define a different source language than English. The second one allows to release only a subset of the languages available in the "locale" folder. (Thanks to this little enhancement we have been able to drop the Spanish, Chinese and Italian translations from this release, they will be back when in a good shape.) Support has been added for the metadata field "dc:subject" to every CMS object. Now the fields "dc:description" and "dc:subject" are used to build the <meta> tags "description" and "keywords", to improve the behaviour with search engines. Also, the <title> tag has been fixed for web-site objects. The still experimental "Table" handler has earned a user interface (in "itools.cms"). There are also user interface improvements to the tracker and the HTML editor. Better support for compressed files. Locking files with the external editor works. And backwards compatibility fixes for the forum. Regarding the programming interface we have a number of enhancements: - [itools.datatypes] Add the base class method "_get_options" to the Enumerate data-type, so it will be easier to define enumerate fields whose options are not hard-coded. - [itools.handlers] Now the "Config.get_value" method accepts the optional parameter "default". - [itools.cms] New utility function "generate_name", useful to find out a name that does not clashes with other names. - [itools.cms] Now the "OrderAware" class makes the difference beween ordered and not-ordered objects. The "get_ordered_folder_names" method gains the optional parameter "mode" to control the information returned. Credits: - Nicolas Deram worked on itools.cms; - J. David Ibáñez implemented isetup-copyright and fixed bugs; - Henry Obein worked on itools.cms and the "Table" handler; - Sylvain Taverne worked on itools.cms and the "setup.conf" file; Resources --------- Download http://download.ikaaro.org/itools/itools-0.16.5.tar.gz Home http://www.ikaaro.org/itools Mailing list http://mail.ikaaro.org/mailman/listinfo/itools Bug Tracker http://bugs.ikaaro.org/ -- J.

by Arjan Molenaar Aug. 2, 2007

Aug. 2, 2007

Hi all, After another few weeks of hard work, Gaphor 0.11.1 and Gaphas 0.3.0 are out. Gaphor is an UML 2.0 modeling environment written in Python. It's quite extensible and uses GTK+ for it's GUI. Gaphas is Gaphor's canvas widget (the thing you draw your (UML) diagrams on). It's also pure Python, utilizing Cairo <http://cairographics.org> for rendering. Major improvement: speed! The canvas (Gaphas) has been improved quite a bit. Homepage: http://gaphor.devjavu.com Grab your copy from (or use easy_install): http://cheeseshop.python.org/pypi/gaphor http://cheeseshop.python.org/pypi/gaphas Other improvements: Gaphas ------ * Major performance improvements * more consistent API * Views use Quadtree's for item placement and retrieval * Support for decorator 2.2 syntax Gaphor ------ * Few minor fixes * Support for Gaphas 0.3.0 API Regards, Arjan Molenaar

Jython 2.2 RC3 is available
by Charlie Groves Aug. 2, 2007

Aug. 2, 2007

The Jython development team is pleased to announce that Jython 2.2rc3 is available for download: http://downloads.sourceforge.net/jython/jython_installer-2.2rc3.jar See http://jython.org/Project/installation.html for installation instructions. A few new pieces of functionality have been added since 2.2rc2: - Added telnetlib from CPython - Added cpython_compatible_select to select. See http://wiki.python.org/jython/SelectModule for information on when to use it. - Several more java.nio exceptions are mapped to their corresponding Python error codes when thrown. The following bugs are also fixed in this release: - recv on closed sockets threw an exception instead returning the empty string - A PySystemState being garbage collected caused System.out and System.in to be closed. This would cause 'print' to stop working. - Closing a FileWrapper on a socket closes its underlying socket - Sockets just have their [In|Out]putStreams closed instead of being properly shutdown by shutdown() - SO_REUSEADDR is reset on sockets from a server socket's accept call causing later binds to the server socket's port to fail. - Client sockets that have bind called before connect don't respect SO_REUSEADDR - execfile() throws a NullPointerException in the interactive console Enjoy! Charlie
