ANNOUNCE: PyGObject 2.12.0
by Johan Dahlin Sept. 5, 2006

Sept. 5, 2006

I am pleased to announce version 2.12.0 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/2.12/ What's new since PyGObject 2.11.3: - Install the html files even when using --disable-docs (#353159, Johan, Matthias Clasen) 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 GObject >= 2.8.0 and Python >= 2.3.5 to build. What's new in 2.12.0? * John Finlays reference manual is now included and prebuilt * GOption is now supported * Support for signal emission hooks * Various GInterface related improvements * Many bug fixes Acknowledgements: Thanks to everybody who helped making this release possible: Gustavo J. A. M. Carneiro Matthias Clasen Murray Cumming John Ehresman John Finlay Cedric Gustin Johannes Hölzl Kjartan Maraas Yevgen Muntyan Gian Mario Tagliaretti Andy Wingo -- Johan Dahlin jdahlin(a)async.com.br

Fault-tolerance framework Py-Fate 1.4 released
by dmitry＠targeted.org Sept. 2, 2006

Sept. 2, 2006

Fault-tolerance framework Py-Fate contains several proxy classes and/or algorithms so that a conscious developer can easily add fault-tolerance to the code. http://sourceforge.net/projects/py-fate/ The biggest point is that Python proxying capabilities allow for invisible drop-in addition or revocation of fault tolerance. Using Py-Fate you can turn any callable into a syntactically identical callable with fault-tolerant twist, for example: --------------------------------------------------- "Sequential" fault-tolerance through repetition: def foo(...): ... foo(...) # regular foo call foo = ft_retry(ft_sync(foo), 3) foo(...) # now foo gets retried up to 3 times in case it throws foo = ft_retry(ft_async(foo, 10.0), 3) foo(...) # same but each retry of foo also times out in 10 seconds foo = ft_retry_backoff(ft_async(foo, 10.0), 1.0, 3) foo(...) # same but exponentially increasing sleep is inserted between the retries, exactly 1, 2, and 4 seconds in this example --------------------------------------------------- "Parallel" fault-tolerance through simultaneous execution of multiple variants of the same code: def foo1(...): ... def foo2(...): # has the same signature as foo1 ... foo = ft_par_1st(ft_succeeded, ft_sync(foo1), ft_sync(foo2)) foo(...) # runs foo1 and foo2 in parallel and whichever returns first and manages not to throw wins def foo3(...): # has the same signature as both the other foo's ... foo = ft_par(ft_majority_voter(), ft_sync(foo1), sync(foo2), sync(foo3)) foo(...) # runs all three in parallel and performs majority voting on the results foo = ft_par_tb(ft_equal_comparator(), ft_sync(foo1), sync(foo2), sync(foo3)) foo(...) # similar to the previous but doesn't wait for all the foo's to return as soon as there is enough identical votes Obviously, there is a handful other templates and more details, please see the module documentation. --------------------------------------------------- Please download Py-Fate here: http://sourceforge.net/projects/py-fate/

ANN: GMPY binaries for Python 2.5
by casevh＠comcast.net Sept. 1, 2006

Sept. 1, 2006

GMPY binaries for Python 2.5 are available at http://home.comcast.net/~casevh/ Notes ==== They have not been extensively tested. This is based on the CVS version of gmpy and includes a patch (not yet in CVS) from Alex Martelli that resolves a bug with divm(). Please consider this an "unofficial" release. The patch and the source code snapshot I used are also available on the website. GMP 4.2.1 is used. There are three versions available: one that should work on any processor, one compiled for Pentium 4 processor, and one compiled for AMD Athlon (32-bit). If there is demand, I'll create updated binaries for earlier version of Python. Enjoy, casevh
