semantic web(2py)
by Massimo Di Pierro 21 Dec '09

21 Dec '09

http://www.web2py.com/semantic The idea of the semantic web, embodied by Linked Data, is that of labeling relations between data using the Web Ontology Language (OWL) and post the data online using an XML based protocol (RDF). Now you can do it in web2py by simply labeling fields and tables in the Database Abstraction Layer (DAL) with .rdf={...} and installing this plugin. The plugin exposes a web service that publishes your database as Linked Data (only tables labeled with rdf). This system works with new and with most legacy databases. It transparently supports SQLite, MySQL, PostgreSQL, MSSQL, Oracle, FireBird, Informix, DB2, Ingres, and the Google App Engine. If you are interested in this area, please let us know. We could use some feedback.

Roundup Release 1.4.11
by Richard Jones 21 Dec '09

21 Dec '09

I'm proud to release version 1.4.11 of Roundup which fixes a number bugs and closes a potential security hole. ALL tracker maintainers MUST read the upgrading documentation to make sure the hole is fixed in their tracker. Other changes in this release: - Generic class editor may now restore retired items (thanks Ralf Hemmecke) - Fix security hole allowing user permission escalation (thanks Ralf Schlatterbeck) - More SSL fixes. SSL wants the underlying socket non-blocking. So we don't call socket.setdefaulttimeout in case of SSL. This apparently never raises a WantReadError from SSL. This also fixes a case where a WantReadError is raised and apparently the bytes already read are dropped (seems the WantReadError is really an error, not just an indication to retry). - Correct initial- and end-handshakes for SSL - Update FAQ to mention infinite redirects with pathological settings of the tracker->web variable. Closes issue2537286, thanks to "stuidge" for reporting. - Fix some format errors in italian translation file - Some bugs issue classifiers were causing database lookup errors - Fix security-problem: If user hasn't permission on a message (notably files and content properties) and is on the nosy list, the content was sent via email. We now check that user has permission on the message content and files properties. Thanks to Intevation for funding this fix. - Fix traceback on .../msgN/ url, this requests the file content and for apache mod_wsgi produced a traceback because the mime type is None for messages, fixes issue2550586, thanks to Thomas Arendsen Hein for reporting and to Intevation for funding the fix. - Handle OPTIONS http request method in wsgi handler, fixes issue2550587. Thanks to Thomas Arendsen Hein for reporting and to Intevation for funding the fix. - Add documentation for migrating to the Register permission and fix mailgw to use Register permission, fixes issue2550599 - Fix styling of calendar to make it more usable, fixes issue2550608 - Fix typo in email section of user guide, fixes issue2550607 - Fix WSGI response code (thanks Peter Pöml) - Fix linking of an existing item to a newly created item, e.g. edit action in web template is name="issue-1@link@msg" value="msg1" would trigger a traceback about an unbound variable. Add new regression test for this case. May be related to (now closed) issue1177477. Thanks to Intevation for funding the fix. - Clean up all the places where role processing occurs. This is now in a central place in hyperdb.Class and is used consistently throughout. This also means now a template can override the way role processing occurs (e.g. for elaborate permission schemes). Thanks to intevation for funding the change. - Fix issue2550606 (german translation bug) "an hour" is only used in the context "in an hour" or "an hour ago" which translates to german "in einer Stunde" or "vor einer Stunde". So "an hour" is translated "einer Stunde" (which sounds wrong at first). Also note that date.py already has a comment saying "XXX this is internationally broken" -- but at least there's a workaround for german :-) Thanks to Chris (radioking) for reporting. 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).

cx_Freeze 4.1.1
by Anthony Tuininga 20 Dec '09

20 Dec '09

What is cx_Freeze? cx_Freeze is a set of scripts and modules for freezing Python scripts into executables in much the same way that py2exe and py2app do. It requires Python 2.3 or higher since it makes use of the zip import facility which was introduced in that version. Where do I get it? http://cx-freeze.sourceforge.net What's new? Changes from 4.1 to 4.1.1 1) Added support for Python 3.1. 2) Added support for 64-bit Windows. 3) Ensured that setlocale() is called prior to manipulating file names so that names that are not encoded in ASCII can still be used. 4) Fixed bug that caused the Python shared library to be ignored and the static library to be required or a symbolic link to the shared library created manually. 5) Added support for renaming attributes upon import and other less frequently used idioms in order to avoid as much as possible spurious errors about modules not being found. 6) Force inclusion of the traceback module in order to ensure that errors are reported in a reasonable fashion. 7) Improved support for the execution of ldd on the Solaris platform as suggested by Eric Brunel. 8) Added sample for the PyQt4 package and improved hooks for that package. 9) Enhanced hooks further in order to perform hidden imports and avoid errors about missing modules for several additional commonly used packages and modules. 10) Readded support for the zip include option. 11) Avoid the error about digest mismatch when installing RPMs by modifying the spec files built with cx_Freeze. 12) Ensure that manifest.txt is included in the source distribution.

ANNOUNCE: awstats_reader 0.5
by Joshua Kugler 19 Dec '09

19 Dec '09

ABOUT THE MODULE ================ AwstatsReader is a pythonic interface to AWStats data cache files. Using it, you can access year and month via dict-like subscripts, and and individual data points via both dict-like subscripts and attribute-like accessors. As of version 0.5, it includes a script for merging AWStats Cache files. Download: http://azariah.com/open_source.html ABOUT THE AUTHOR ================ Joshua Kugler (joshua(a)azariah.com) is a programmer and system administator with over 10 years of industory experience. He is currently looking for a job. Happen to have one you could offer him? :) Resume at: http://jjncj.com/papers/KuglerResume.pdf DISCLAIMER ========== This is an early-beta release. There are 43 tests which cover most, if not all of the functionality, but not much documentation. The interface should be considered stable, but not in concrete. The usage of this project in a "real world" situation (awstats_cache_merge.py) led to many improvements to the API. I wrote this via examples from an AWStats cache file, so I'm sure there are sections for which I do not have definitions. If you would send me those sections, I'll be sure to add them. Right now, this will parse and display cache files from AWStats 6.5. I've not tested other versions yet, as 6.5 is the only version I've had access to so far. REPOSITORY ========== No public repository yet. Just haven't set it up. LICENSE ======= Modified BSD EXAMPLE ======= import awstats_reader obj = awstats_reader.AwstatsReader('/path/to/awstats_logs', 'example.com') print obj[2007] print obj[2008][6] m = obj[2009][7] print m['general'] # Access like a dictionary... print m['general']['LastLine'] #...or like an object attribute print m['general'].LastLine print m.general.LastLine FEEDBACK ======== Please send questions/comments/suggestions to awstatsreader(a)azariah.com For now, you can find the latest version here: http://azariah.com/open_source.html

[ANNOUNCE] PyGobject 2.21.0 - unstable
by Gian Mario Tagliaretti 18 Dec '09

18 Dec '09

I am pleased to announce version 2.21.0 of the Python bindings for GObject. The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://download.gnome.org/sources/pygobject/2.21/ What's new since PyGObject 2.20.0? - pygmainloop: fix use of PySignal_WakeUpFD API for nested loops (Philippe Normad, #481569) - Add capabilities to import wrappers from pygi (Simon van der Linden) - Move threads_init() function from 'gobject' to 'glib' (Paul) - Fix wrong minimum checking in float properties (Paul, #587637) - Wrap new API added in GIO 2.22 (Gian Mario) - Fix bad name when rebuilding the unix source module (Gian Mario) - Add the missing limit constants from glibconfig.h (Tomeu Vizoso, #603244) - Suppress warnings about format conversion (Simon van der Linden, #603355) - Properly define Connectable as interface type and not object type (Gian Mario) - Wrap new API added in GIO-UNIX 2.22 (Gian Mario) - Wrap g_find_program_in_path (Gian Mario, #598435) - Add pygi-external.h into Makefile SOURCES (Gian Mario) Blurb: GObject is a object system library used by GTK+ and GStreamer. PyGObject provides a convenient wrapper for the GObject library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyGTK, PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject requires glib >= 2.22.4 and Python >= 2.3.5 to build. GIO bindings require glib >= 2.22.4. Please remember that this is an unstable release and shouldn't be used in production. cheers -- Gian Mario Tagliaretti GNOME Foundation member gianmt(a)gnome.org
