TextTest 3.20 : blackbox testing with a Python slant
by Geoff Bache 30 Sep '10

30 Sep '10

Hi all, There's a new version of the black-box test tool TextTest out. Various enhancements and bug fixes, notably - Tests can be rerun from the dynamic GUI with different settings - Config file settings can now be varied per test - Can now set up a "known bug" that will trigger a rerun of the test up to a certain number of times Note this release requires at least Python 2.6 and PyGTK 2.16 now. Regards, Geoff Bache .... TextTest is a tool for automatic text-based functional testing. This means running a batch-mode executable in lots of different ways from the command line, and using the text output produced as a means of controlling the behavior of that application. As well as being usable "standalone", it is an extendable framework for black-box testing written in Python. It's also useful as a test management tool wrapping some other test tool as a test runner.

PyUseCase 3.4: Python GUI test tool
by Geoff Bache 30 Sep '10

30 Sep '10

Hi all, PyUseCase now includes basic support for wxPython, as well as Tkinter and PyGTK. There are also a fair few enhancements and bugfixes for PyGTK, notably gtk.Dialog.run is now supported without requiring source code changes. PyUseCase also now requires at least Python 2.6 and PyGTK 2.12. The legacy instrumentation-based interface has now been removed. Full details are in the ChangeLog in the download. Regards, Geoff Bache A bit more detail: PyUseCase is an unconventional GUI testing tool for PyGTK and Tkinter, along with a framework for testing Python GUIs in general. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates this language into actions on the current GUI widgets. The point is to reduce coupling, allow very expressive tests, and ensure that GUI changes mean changing the UI map file but not all the tests. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it. The point is then to use that as a baseline for text-based testing, using e.g. TextTest. It also includes support for instrumenting code so that "waits" can be recorded, making it far easier for a tester to record correctly synchronized tests without having to explicitly plan for this.

Pyro 4.2 released!
by Irmen de Jong 28 Sep '10

28 Sep '10

Pyro 4.2 --------- I'm pleased to announce the release of Pyro 4.2! Detailed info here: http://www.razorvine.net/python/Pyro Download here: http://www.xs4all.nl/~irmen/pyro4/download/ Python package index entry: http://pypi.python.org/pypi/Pyro4 License: MIT software license. Note: Pyro 4 is not finalized, this is still a beta release. Changes ------- The most important changes compared to Pyro 4.1 are: - toplevel package renamed to Pyro4 to allow parallel installation of Pyro 3.x and Pyro4 - python 3.x compatibility What is Pyro? ------------- PYthon Remote Objects provides a very easy way of remote communication between python objects somewhere in a network. It enables you to do remote method calls on objects as if they were normal local objects. Objects can be located by a direct identifier or indirectly by logical, humanly-readable names that are managed in a name server. Pyro is designed to be simple (but powerful) so it's only a manner of adding a few lines of code to ignite your objects. Simple example: http://www.razorvine.net/python/Pyro/Example Enjoy, Irmen de Jong

[ANN] (probably) last version of Pylint supporting python 2.3 released
by Sylvain Thénault 28 Sep '10

28 Sep '10

Hi there! As someone stuck with python 2.3 tried to use pylint, we made some fixes to get python 2.3 supports back. This resulted in the release of pylint 0.21.3, logilab-astng 0.20.3 and logilab-common 0.52 today. At the time of porting pylint to py3k, this will much probably be the latest set of versions to use to get pylint working with python 2.3 code. And maybe, unless you people think it would be a shame, also for python 2.4, so we can drop support for the old compiler module. ciao, -- Sylvain Thénault LOGILAB, Paris (France) Formations Python, Debian, Méth.

bzr 2.2.1 released !
by Vincent Ladeuil 28 Sep '10

28 Sep '10

The Bazaar team is happy to announce availability of a new release of the bzr adaptive version control system. Bazaar is part of the GNU system <http://gnu.org/>. This is a bugfix release which also includes bugfixes from 2.0.6 and 2.1.3. None are critical, but upgrading is recommended for all users on earlier 2.2 releases. Thanks to everyone who contributed patches, suggestions, and feedback. Bazaar is now available for download from https://launchpad.net/bzr/2.2/2.2.1/ as a source tarball. Packages are already available for Ubuntu, FreeBSD and others. Installers are available for OSX, windows installers should be available Really Soon Now (watch the url above where they should pop up as soon as they become available). bzr 2.2.1 ######### :2.2.1: 2010-09-17 This is a bugfix release which also includes bugfixes from 2.0.6 and 2.1.3. None are critical, but upgrading is recommended for all users on earlier 2.2 releases. Bug Fixes ********* * Additional merges after an unrelated branch has been merged with its history no longer crash when deleted files are involved. (Vincent Ladeuil, John Arbash Meinel, #375898) * ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a previously-unversioned directory within the tree: the directory is marked versioned too. (Martin Pool, #192859) * ``bzr commit SYMLINK`` now works, rather than trying to commit the target of the symlink. (Martin Pool, John Arbash Meinel, #128562) * ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same permissions as ``.bzr`` directory on a POSIX OS. (Parth Malwankar, #262450) * CommitBuilder now uses the committer instead of _config.username to generate the revision-id. (Aaron Bentley, #614404) * Configuration files in ``${BZR_HOME}`` are now written in an atomic way which should help avoid problems with concurrent writers. (Vincent Ladeuil, #525571) * Cope with Microsoft FTP server that returns reply '250 Directory created' when mkdir succeeds. (Martin Pool, #224373) * Don't traceback trying to unversion children files of an already unversioned directory. (Vincent Ladeuil, #494221) * Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g. contains only NUL bytes). Instead warn the user, and allow ``bzr break-lock`` to remove it. (Andrew Bennetts, #619872) * Fix ``AttributeError on parent.children`` when adding a file under a directory that was a symlink in the previous commit. (Martin Pool, #192859) * Fix ``AttributeError: 'NoneType' object has no attribute 'close'`` in ``_close_ssh_proc`` when using ``bzr+ssh://``. This was causing connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on stderr in some other circumstances. (Andrew Bennetts, #633745) * Only call ``setlocale`` in the bzr startup script on posix systems. This avoids an issue with the newer windows C runtimes used by Python 2.6 and later which can mangle bytestrings printed to the console. (Martin [gz], #631350) * Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps, which can result in "missing referenced chk root keys" errors when fetching from repositories with affected revisions. (Andrew Bennetts, #522637) * Raise ValueError instead of a string exception. (John Arbash Meinel, #586926) * Reduce peak memory by one copy of compressed text. (John Arbash Meinel, #566940) * Repositories accessed via a smart server now reject being stacked on a repository in an incompatible format, as is the case when accessing them via other methods. This was causing fetches from those repositories via a smart server (e.g. using ``bzr branch``) to receive invalid data. (Andrew Bennetts, #562380) * Selftest with versions of subunit that support ``stopTestRun`` will no longer error. This error was caused by 2.0 not being updated when upstream python merged the end of run patch, which chose ``stopTestRun`` rather than ``done``. (Robert Collins, #571437) * Stop ``AttributeError: 'module' object has no attribute 'ElementTree'`` being thrown from ``xml_serializer`` on certain cElementTree setups. (Martin [gz], #254278) * Upgrading or fetching from a non-rich-root repository to a rich-root repository (e.g. from pack-0.92 to 2a) no longer fails with ``'Inter1and2Helper' object has no attribute 'source_repo'``. This was a regression from Bazaar 2.1. (Andrew Bennetts, #636930) * When passing a file to ``UTF8DirReader`` make sure to close the current directory file handle after the chdir fails. Otherwise when passing many filenames into a command line ``bzr status`` we would leak descriptors. (John Arbash Meinel, #583486) Documentation ************* * Fix a lot of references in the docs to the old http://bazaar-vcs.org to the new http://bazaar.canonical.com or http://wiki.bazaar.canonical.com (John Arbash Meinel, #617503) Internals ********* * Remove used and broken code path in ``BranchInitHookParams.__repr__``. (Andrew Bennetts) Testing ******* * ``build_tree_contents`` can create symlinks. (Martin Pool, John Arbash Meinel) * Tracebacks from a parameterized test are no longer reported against every parameterization of that test. This was done by adding a hack to ``bzrlib.tests.clone_test`` so that it no longer causes testtools.TestCase instances to share a details dict. (Andrew Bennetts, #625574)

[ANNOUNCE] PyGObject 2.26.0 - stable release
by John Palmieri 27 Sep '10

27 Sep '10

I am pleased to announce version 2.26.0 of the Python bindings for GObject. Including the stable improvements in the base pygobject modules this is the first stable release to include the Introspection modules. These new modules are considered beta quality and we don't guarantee API compatibility with future versions yet. Python 3 support, limited to the base and Introspection modules, also ships for the first time in this release. To build with Python 3 support set the PYTHON env variable to your Python 3 executable during the configure stage: $ PYTHON=python3 ./configure 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/2.26/ What's new since PyGObject 2.21.5? - Wrap g_get_system_{config,data}_dirs () (John Strowers) - fixed make check and make dist (John (J5) Palmieri) - Disable GI tests when introspection disabled (John Stowers) - Wrap g_uri_list_extract_uris.

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 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 gobject-introspection bugs are being fixed at a rapid pace so it is recommend to use the latest version in git when filing bugs against the Introspection module. -- John (J5) Palmieri GNOME Foundation member johnp(a)redhat.com
