[ANN] ftputil 2.6 released
by Stefan Schwarzer 12 Mar '11

12 Mar '11

ftputil 2.6 is now available from http://ftputil.sschwarzer.net/download . Changes since version 2.5 ------------------------- - The stat caching has been improved. There's now an "auto-grow" feature for `FTPHost.listdir` which in turn applies to `FTPHost.walk`. Moreover, there are several performance optimizations. - A few bugs were fixed [1-3]. - ftputil now requires at least Python 2.4 (but doesn't work with Python 3). What is ftputil? ---------------- ftputil is a high-level FTP client library for the Python programming language. ftputil implements a virtual file system for accessing FTP servers, that is, it can generate file-like objects for remote files. The library supports many functions similar to those in the os, os.path and shutil modules. ftputil has convenience functions for conditional uploads and downloads, and handles FTP clients and servers in different timezones. Read the documentation at http://ftputil.sschwarzer.net/documentation . License ------- ftputil is Open Source software, released under the revised BSD license (see http://www.opensource.org/licenses/bsd-license.php ).

pytest-2.0.2: bug fixes, improved xfail/skip expressions, speedups
by holger krekel 09 Mar '11

09 Mar '11

Welcome to pytest-2.0.2, a maintenance and bug fix release. py.test is a mature testing tool for Python, supporting CPython 2.4-3.2, Jython and latest PyPy interpreters. See the extensive docs with tested examples here: http://pytest.org/ If you want to install or upgrade pytest, just type one of:: pip install -U pytest # or easy_install -U pytest Many thanks to all issue reporters and people asking questions or complaining, particularly Jurko for his insistence, Laura, Victor and Brianna for helping with improving and Ronny for his general advise. best, holger krekel Changes between 2.0.1 and 2.0.2 ---------------------------------------------- - tackle issue32 - speed up test runs of very quick test functions by reducing the relative overhead - fix issue30 - extended xfail/skipif handling and improved reporting. If you have a syntax error in your skip/xfail expressions you now get nice error reports. Also you can now access module globals from xfail/skipif expressions so that this for example works now:: import pytest import mymodule @pytest.mark.skipif("mymodule.__version__[0] == "1") def test_function(): pass This will not run the test function if the module's version string does not start with a "1". Note that specifying a string instead of a boolean expressions allows py.test to report meaningful information when summarizing a test run as to what conditions lead to skipping (or xfail-ing) tests. - fix issue28 - setup_method and pytest_generate_tests work together The setup_method fixture method now gets called also for test function invocations generated from the pytest_generate_tests hook. - fix issue27 - collectonly and keyword-selection (-k) now work together Also, if you do "py.test --collectonly -q" you now get a flat list of test ids that you can use to paste to the py.test commandline in order to execute a particular test. - fix issue25 avoid reported problems with --pdb and python3.2/encodings output - fix issue23 - tmpdir argument now works on Python3.2 and WindowsXP Starting with Python3.2 os.symlink may be supported. By requiring a newer py lib version the py.path.local() implementation acknowledges this. - fixed typos in the docs (thanks Victor Garcia, Brianna Laugher) and particular thanks to Laura Creighton who also revieved parts of the documentation. - fix slighly wrong output of verbose progress reporting for classes (thanks Amaury) - more precise (avoiding of) deprecation warnings for node.Class|Function accesses - avoid std unittest assertion helper code in tracebacks (thanks Ronny)

[ANNOUNCE] PyGObject 2.28.0 - stable
by John Palmieri 08 Mar '11

08 Mar '11

I am pleased to announce version 2.28.0 of the Python bindings for GObject. Including the stable improvements in the base pygobject modules this is the first stable release of the Introspection binding. PyGObject Introspection is compatible with both the Python 2 and Python 3 runtimes. This marks the second major development project I have had the pleasure to help bring to fruition. Like for D-Bus, I am merely the public face of a rather vibrant development community. While I hope I don't leave anyone out I would like to thank the following people who dedicated their valuable time to the future of the Python platform for GNOME. • Johan Dahlin - creator of PyBank, the predecessor to PyGObject Introspection, for giving us direction, advice and helping to review patches • Tomeu Vizoso - co-maintainer, my good friend, the reason why we decided to push for Introspection support and probably the hardest worker on our team • Steve Frécinaux - for all of his leak hunting and bug fixing while testing against libpeas and gedit plugins • Ignacio Casal Quinterio - for fixing bugs while porting the gedit plugins to the new bindings • Laszlo Pandy - for fixing some of the tougher bugs and winning the "why are you awake at this hour, hacking on PyGObject while on irc?" award • Martin Pitti - who worked on GVarients and making GDBus easy to use from PyGObject • Simon van der Linden - who started this journey with us and has been helping us along when he finds the time • Simon Schampijer - our newcomer from OLPC/Sugar development who jumped right in to help at the hackfest• • Sebastian Pölsterl - another hackfest alum who ported GNOME DVB Daemon's GUI • John Ehresman - creator of the initial Python 3 support code • Dave Malcolm - some of the initial Python 3 bits and my sounding board for any Python issues I ran into • The entire GObject Introspection team - especially the tireless Colin Walters who fixed our many GI bugs quickly while also putting up with my complaining both at work and whenever we happened to grab a beer in one of the local watering holes • The Python team - for making an excellent language for us to bind to The new release is available from ftp.gnome.org: http://download.gnome.org/sources/pygobject/2.28/ What's new since PyGObject 2.27.92? • fix sinking of floating objects • fix leaks when setting properties • add basic icon view demo • add search entry demo • override Gdk.RGBA so you can construct it like Gdk.RGBA(1.0, 1.0, 1.0, 1.0) • handle unichar gvalues in TreeModels • check for _thread module when configuring threading • package config file now contains overridesdir variable for 3rd party overrides • on windows set bdist_wininst user-access-control property when installing • Gtk.stock_lookup return None on failure instead of a success value • Python 2.5 fixes • Python 3 fixes 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 >= 2.5.1 to build. GIO bindings require glib >= 2.22.4. The Introspection module is the next generation Python GObject library bindings. Instead of statically wrapping every GObject based library we can now dynamically accesses any of those libraries using GObject Introspection. It replaces the need for separate modules such as PyGTK, GIO and python-gnome to build a full GNOME 3.0 application. Once new functionality is added to gobject library it is instantly available as a Python API without the need for an intermediate Python module. Introspection/Python 2 bindings requires gobject-introspection >= 0.9.5 and pycairo >=1.0.2 or py2cairo >=1.8.10 Introspection/Python 3 bindings requires gobject-introspection >= 0.9.5, pycairo >=1.8.10 and Python >= 3.1 -- John (J5) Palmieri GNOME Foundation member johnp(a)redhat.com

[ANN] Bento 0.0.5, a packaging solution for python software
by David Cournapeau 08 Mar '11

08 Mar '11

Hi, I am pleased to announce a new release of bento, a packaging solution for python which aims at reproducibility, extensibility and simplicity. You can take a look at its main features on bento's main documentation page (http://cournape.github.com/Bento). The main features of this 0.0.5 release are: - All python versions from 2.4 up to 3.1 now pass the test suite (3.2 will follow once a distribute issue with 3.2 is fixed) - If run under a virtual environment (virtualenv), bento will install the package inside the virtualenvironment by default - Internal changes to enable easier change of build tool (an example for simple extensions is available for waf 1.6.x) - Added experimental distutils compatibility layer so that one can write a setup.py which will pick up all information from bento.info. This enables projects using bento to be able to use tools such as pip. Bento now has its own mailing list: bento(a)librelist.com. If you are curious about bento, I will present it at pycon 2011 as a poster. cheers, David
