I just released a new PyGObject, for GNOME 3.7.3 which is due on Wednesday.

This is mostly a bug fix release. There is one API addition, it brings back official support for calling GLib.io_add_watch() with a Python file object or fd as first argument, in addition to the official API which expects a GLib.IOChannel object. These modes were marked as deprecated in 3.7.2 (only).

Thanks to all contributors!

Summary of changes (see change log for complete details):

  • Add support for caller-allocated GArray out arguments (Martin Pitt) (#690041)
  • Re-support calling GLib.io_add_watch with an fd or Python file (Martin Pitt)
  • pygtkcompat: Work around IndexError on large flags (Martin Pitt)
  • Fix pyg_value_from_pyobject() range check for uint (Martin Pitt)
  • Fix tests to work with g-i 1.34.2 (Martin Pitt)
  • Fix wrong refcount for GVariant property defaults (Martin Pitt) (#689267)
  • Fix array arguments on 32 bit (Martin Pitt)
  • Add backwards compatible API for GLib.unix_signal_add_full() (Martin Pitt)
  • Drop MININT64/MAXUINT64 workaround, current g-i gets this right now (Martin Pitt)
  • Fix maximum and minimum ranges of TYPE_(U)INT64 properties (Simonas Kazlauskas) (#688949)
  • Ship pygi-convert.sh in tarballs (Martin Pitt) (#688697)
  • Various added and improved tests (Martin Pitt)

I just released Apport 2.7.

The main new feature is supporting foreign architectures in apport-retrace. If apport-retrace works in sandbox mode and works on a crash that was not produced on the same architecture as apport-retrace is running on, it will now build a sandbox for the report’s architecture and invoke gdb with the necessary magic options to produce a proper stack trace (and the other gdb information).
Right now this works for i386, x86_64, and ARMv7, but if someone is interested in making this work for other architectures, please ping me.

This is rolled out to the Launchpad retracers, see for example Bug #1088428. So from now on you can report your armhf crashes to Launchpad and they ought to be processed. Note that I did a mass-cleanup of old armhf crash bugs this morning, as the existing ones were way too old to be retraced.

For those who are running their own retracers for their project: You need to add an armhf specific apt sources list your per-release configuration directory, e. g. Ubuntu 12.04/armhf/sources.list as armhf is on ports.ubuntu.com instead of archive.ubuntu.com. Also, you need to add an armhf crash database to your crashdb.conf and add a cron job for the new architecture. You can see how all this looks like in the configuration files for the Launchpad retracers.

The other improvement concerns package hooks. So far, when a package hook crashed the exception was only printed to stderr, where most people would never see them when using the GTK or KDE frontend. With 2.7 these exceptions are also added to the report itself (HookError_filename), so that they appear in the bug reports.

The release also fixes a couple of bugs, see the release notes for details.

just released a new PyGObject, for GNOME 3.7.2 which is due on Wednesday.

In this version PyGObject went through some major refactoring: Some 5.000 lines of static bindings were removed and replaced with proper introspection and some overrides for backwards compatibility, and the static/GI/overrides code structure was simplified. For the developer this means that you can now use the full GLib API, a lot of which was previously hidden by old and incomplete static bindings; also you can and should now use the officially documented GLib API instead of PyGObject’s static one, which has been marked as deprecated. For PyGObject itself this change means that the code structure is now a lot simpler to understand, all the bugs in the static GLib bindings are gone, and the GLib bindings will not go out of sync any more.

Lots of new tests were written to ensure that the API is backwards compatible, but experience teaches that ther is always the odd corner case which we did not cover. So if your code does not work any more with 3.7.2, please do report bugs.

Another important change is that if you build pygobject from source, it now defaults to using Python 3 if installed. As before, you can build for Python 2 with PYTHON=python2.7 or the new --with-python=python2.7 configure option.

This release also brings several marshalling fixes, docstring improvements, support for code coverage, and other bug fixes.

Thanks to all contributors!

Summary of changes (see changelog for complete details):

  • [API change] Drop almost all static GLib bindings and replace them with proper introspection. This gets rid of several cases where the PyGObject API was not matching the real GLib API, makes the full GLib API available through introspection, and makes the code smaller, easier to maintain. For backwards compatibility, overrides are provided to emulate the old static binding API, but this will throw a PyGIDeprecationWarning for the cases that diverge from the official API (in particular, GLib.io_add_watch() and GLib.child_watch_add() being called without a priority argument). (Martin Pitt, Simon Feltman)
  • [API change] Deprecate calling GLib API through the GObject namespace. This has always been a misnomer with introspection, and will be removed in a later version; for now this throws a PyGIDeprecationWarning.
  • [API change] Do not bind gobject_get_data() and gobject_set_data(). These have been deprecated for a cycle, now dropped entirely. (Steve Frécinaux) (#641944)
  • [API change] Deprecate void pointer fields as general PyObject storage. (Simon Feltman) (#683599)
  • Add support for GVariant properties (Martin Pitt)
  • Add type checking to GVariant argument assignment (Martin Pitt)
  • Fix marshalling of arrays of struct pointers to Python (Carlos Garnacho) (#678620)
  • Fix Gdk.Atom to have a proper str() and repr() (Martin Pitt) (#678620)
  • Make sure g_value_set_boxed does not cause a buffer overrun with GStrvs (Simon Feltman) (#688232)
  • Fix leaks with GValues holding boxed and object types (Simon Feltman) (#688137)
  • Add doc strings showing method signatures for gi methods (Simon Feltman) (#681967)
  • Set Property instance doc string and blurb to getter doc string (Simon Feltman) (#688025)
  • Add GObject.G_MINSSIZE (Martin Pitt)
  • Fix marshalling of GByteArrays (Martin Pitt)
  • Fix marshalling of ssize_t to smaller ints (Martin Pitt)
  • Add support for lcov code coverage, and add a lot of missing GIMarshallingTests and g-i Regress tests. (Martin Pitt)
  • pygi-convert: remove deprecated GLib ? GObject conversions (Jose Rostagno)
  • Add support for overriding GObject.Object (Simon Feltman) (#672727)
  • Add –with-python configure option (Martin Pitt)
  • Do not prefer unversioned “python” when configuring, as some distros have “python” as Python 3. Use Python 3 by default if available. Add –with-python configure option as an alternative to setting $PYTHON, whic is more discoverable. (Martin Pitt)
  • Fix property lookup in class hierarchy (Daniel Drake) (#686942)
  • Move property and signal creation into _class_init() (Martin Pitt) (#686149)
  • Fix duplicate symbols error on OSX (John Ralls)
  • [API add] Add get_introspection_module for getting un-overridden modules (Simon Feltman) (#686828)
  • Work around wrong 64 bit constants in GLib Gir (Martin Pitt) (#685022)
  • Mark GLib.Source.get_current_time() as deprecated (Martin Pitt)
  • Fix OverflowError in source_remove() (Martin Pitt) (#684526)

With python-dbusmock you can provide mocks for arbitrary D-BUS services for your test suites or if you want to reproduce a bug.

However, when writing actual tests for gnome-settings-daemon etc. I noticed that it is rather cumbersome to always have to set up the “skeleton” of common services such as UPower. python-dbusmock 0.2 now introduces the concept of “templates” which provide those skeletons for common standard services so that your code only needs to set up the particular properties and specific D-BUS objects that you need. These templates can be parameterized for common customizations, and they can provide additional convenience methods on the org.freedesktop.DBus.Mock interface to provide more abstract functionality like “add a battery”.

So if you want to pretend you have one AC and a half-charged battery, you can now simply do

  def setUp(self):
     (self.p_mock, self.obj_upower) = self.spawn_server_template('upower', {})

  def test_ac_bat(self):
     self.obj_upower.AddAC('mock_AC', 'Mock AC')
     self.obj_upower.AddChargingBattery('mock_BAT', 'Mock Battery', 50.0, 1200)

Or, if your code is not in Python, use the CLI/D-BUS interface, like in shell:

  # start a fake system bus
  eval `dbus-launch`
  export DBUS_SYSTEM_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS

  # start mock upower on the fake bus
  python3 -m dbusmock --template upower &

  # add devices
  gdbus call --system -d org.freedesktop.UPower -o /org/freedesktop/UPower \
      -m org.freedesktop.DBus.Mock.AddAC mock_ac 'Mock AC'
  gdbus call --system -d org.freedesktop.UPower -o /org/freedesktop/UPower \
      -m org.freedesktop.DBus.Mock.AddChargingBattery mock_bat 'Mock Bat' 50.0 1200

In both cases upower --dump or gnome-power-statistics will show you the expected devices (of course you need to run that within the environment of the fake $DBUS_SYSTEM_BUS_ADDRESS, or run the mock on the real system bus as root).

Iftikhar Ahmad contributed a template for NetworkManager, which allows you to easily set up ethernet and wifi devices and wifi access points. See pydoc3 dbusmock.templates.networkmanager for details and the test cases for how this looks like in practice.

I just released python-dbusmock 0.2.1 and uploaded the new version to Debian experimental. I will sync it into Ubuntu Raring in a few hours.

A few days ago Olav Vitters announced the GNOME 3.8 goal of porting to Python 3.

This has been discussed on desktop-devel-list@ in the past days, and the foundations for this are now ready:

  • pygobject now has a –with-python option. (commit)
  • JHBuild now defaults to building pygobject for Python 3, but introduces a “pygobject-python2″ project for the transition phase which provides pygobject built for Python 2. (commit)
  • All dependencies to “pygobject” were changed to “pygobject-python2″ to avoid breaking modules. (commit).

So in theory your modules should continue to build and work in jhbuild just fine. Once you ported a module to Python 3, please switch the dependency back to “pygobject” in jhbuild. (This is now also mentioned on https://live.gnome.org/GnomeGoals/Python3Porting)

Please don’t hesitate to ask me or any fellow PyGObject maintainer in cases of trouble; I’m “pitti” in #python on irc.gnome.org.

Thanks!

I was working on writing tests for gnome-settings-daemon a week or so ago, and finally got blocked on being unable to set up upower/ConsoleKit/etc. the way I need them. Also, doing so needs root privileges, I don’t want my test suite to actually suspend my machine, and using the real service is generally not suitable for test suites that are supposed to run during “make check”, in jhbuild, and the like — these do not have the polkit privileges to do all that, and may not even have a system D-Bus running in the first place.

So I wrote a little test_upower.py helper, then realized that I need another one for systemd/ConsoleKit (for the “system idle” property), also looked at the mock polkit in udisks and finally sat down for two days to generalize this and do this properly.

The result is python-dbusmock, I just released the first tarball. With this you can easily create mock objects on D-Bus from any programming language with a D-Bus binding, or even from the shell.

The mock objects look like the real API (or at least the parts that you actually need), but they do not actually do anything (or only some action that you specify yourself). You can configure their state, behaviour and responses as you like in your test, without making any assumptions about the real system status.

When using a local system/session bus, you can do unit or integration testing without needing root privileges or disturbing a running system. The Python API offers some convenience functions like “start_session_bus()“ and “start_system_bus()“ for this, in a “DBusTestCase“ class (subclass of the standard “unittest.TestCase“).

Surprisingly I found very little precedence here. There is a Perl module, but that’s not particuarly helpful for test suites in C/Vala/Python. And there is Phil’s excellent Bendy Bus, but this has a different goal: If you want to thoroughly test a particular D-BUS service, such as ensuring that it does the right thing, doesn’t crash on bad input, etc., then Bendy Bus is for you (and python-dbusmock isn’t). However, it is too much overhead and rather inconvenient if you want to test a client-side program and just need a few system services around it which you want to set up in different states for each test.

You can use python-dbusmock with any programming language, as you can run the mocker as a normal program. The actual setup of the mock (adding objects, methods, properties, etc.) all happen via D-Bus methods on the “org.freedesktop.DBus.Mock“ interface. You just don’t have the convenience D-Bus launch API.

The simplest possible example is to create a mock upower with a single Suspend() method, which you can set up like this from Python:

import dbus
import dbusmock

class TestMyProgram(dbusmock.DBusTestCase):
[...]
    def setUp(self):
        self.p_mock = self.spawn_server('org.freedesktop.UPower',
                                        '/org/freedesktop/UPower',
                                        'org.freedesktop.UPower',
                                        system_bus=True,
                                        stdout=subprocess.PIPE)

        # Get a proxy for the UPower object's Mock interface
        self.dbus_upower_mock = dbus.Interface(self.dbus_con.get_object(
            'org.freedesktop.UPower', '/org/freedesktop/UPower'),
            'org.freedesktop.DBus.Mock')

        self.dbus_upower_mock.AddMethod('', 'Suspend', '', '', '')

[...]

    def test_suspend_on_idle(self):
        # run your program in a way that should trigger one suspend call

        # now check the log that we got one Suspend() call
        self.assertRegex(self.p_mock.stdout.readline(), b'^[0-9.]+ Suspend$')

This doesn’t depend on Python, you can just as well run the mocker like this:

python3 -m dbusmock org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower

and then set up the mocks through D-Bus like

gdbus call --system -d org.freedesktop.UPower -o /org/freedesktop/UPower \
      -m org.freedesktop.DBus.Mock.AddMethod '' Suspend '' '' ''

If you use it with Python, you get access to the dbusmock.DBusTestCase class which provides some convenience functions to set up and tear down local private session and system buses. If you use it from another language, you have to call dbus-launch yourself.

Please see the README for some more details, pointers to documentation and examples.

Update: You can now install this via pip from PyPI or from the daily builds PPA.

Update 2: Adjusted blog entry for version 0.0.3 API, to avoid spreading now false information too far.

PostgreSQL 9.2 has just been released, after a series of betas and a release candidate. See for yourself what’s new, and try it out!

Packages are available in Debian experimental as well as my PostgreSQL backports PPA for Ubuntu 10.04 to 12.10, as usual.

Please note that 9.2 will not land any more in the feature frozen Debian Wheezy and Ubuntu Quantal (12.10) releases, as none of the server-side extensions are packaged for 9.2 yet.

I just released PyGObject 3.3.91, for GNOME 3.5.91.

The big new feature in this release (thanks to the release team for granting an exception) is Simon Feltman’s new Signal helper class, which makes defining custom signals a whole lot simpler and more obvious. In the past, you had to do

 class C(GObject.GObject):
    __gsignals__ = {
        'my_signal': (GObject.SIGNAL_RUN_FIRST, GObject.TYPE_NONE,
                      (GObject.TYPE_INT,))
    }

    def do_my_signal(self, arg):
        print("my_signal called with %i" % arg)

whereas now this looks like

class C(GObject.GObject):
    @GObject.Signal(arg_types=(int,))
    def my_signal(self, arg):
        print("my_signal called with %i" % arg)

or even more elegantly when using Python 3 and its new type annotations:

class C(GObject.GObject):
    @GObject.Signal
    def my_signal(self, arg:int):
        print("my_signal called with %i" % arg)

Check out the updated example and docstring for other ways how to use it.

Overrides can now be in a directory different from the one that pygobject installs itself into. These overrides need to put this into their __init__.py at the top:

from pkgutil import extend_path
__path__ = extend_path(__path__, __name__)

and put themselves somewhere into the default PYTHONPATH. This should make it a lot easier for library packages to ship their own overrides for Python.

This new version also comes with a couple of new overrides and bug fixes. See the detailled list of changes below.

Thanks to all contributors!

I just released Apport 2.5 with a bunch of new features and some bug fixes.

By default you cannot report bugs and crashes to packages from PPAs, as they are not Ubuntu packages. Some packages like Unity or UbuntuOne define their own crash database which reports bugs against the project instead. This has been a bit cumbersome in the past, as these packages needed to ship a /etc/apport/crashdb.conf.d/ snippet. This has become much easier, package hooks can define a new crash database directly now (#551330):

def add_info(report, ui):
   if determine_whether_to_report_to_upstream:
       report['CrashDB'] = '{ "impl": "launchpad", "project": "picsaw" }'

(Documented in package-hooks.txt)

Apport now also looks for package hooks in /opt (#1020503) if the executable path or a file in the package is somewhere below /opt (it tries all intermediate directories).

With these two, we should have much better support for filing bugs against ARB packages.

This version also finally drops the usage of gksu and moves to PolicyKit. Now we only have one package left in the default install (update-notifier) which uses it. Almost there!

I started to collect some easy PyGObject bugs which are appropriate for the PyGObject hackfest at GUADEC on July 30th. These are bugs which do not need a lot of previous knowlege and are excellent starters for new contributors, such as adding overrides, fixing build system issues, etc.

I also created an initial idea pool/agenda/coordination page, where participants can add or signup for things to work on.

Feel free to add your own topics! I’m really looking forward to GUADEC and the hackfest, see you there!

I just received confirmation that my request for a PyGObject hackfest has been approved by the GUADEC organizers.

If you are developing GObject-introspection based Python applications and have some problems with PyGObject, this is the time and place to get to know each other, getting bugs fixed, learn about pygobject’s innards, or update libraries to become introspectable. I will prepare a list of easy things to look into if you are interested in learning about and getting involved in PyGObject’s development.

See you on July 30th in A Coruña!

I released PyGObject 3.3.3.

The most notable changes are that you can now access methods (and other identifiers) which are Python keywords, PyGObject automatically escapes them now by appending a ‘_’. For example, you can now call myGdkWindow.raise_() or GLib.Thread.yield_() instead of having to resort to the previous workaround getattr(myGdkWindow, 'raise')().

This version also restores the deprecated get_data() and set_data() methods. They were never really meant to be used from Python programs, they can potentially mess up your program and cause crashes, and do not give you anything that regular Python object properties would not already provide in a much safer way (i. e. just write my_obj.foo = 'bar' instead of my_obj.set_data('foo', 'bar')). Apparently some software projects are using them, so they will now raise a deprecation warning and be removed for the GNOME 3.8 cycle instead.

Thanks to all contributors!

Complete list of changes:

  • Remove obsolete release-tag make target (Martin Pitt)
  • Do not do any python calls when GObjects are destroyed after the python interpreter has been finalized (Simon Schampijer) (#678046)
  • Do not change constructor-only “type” Window property (Martin Pitt) (#678510)
  • Escape identifiers which are Python keywords (Martin Pitt) (#676746)
  • Fix code for PEP-8 violations detected by the latest pep8 checker. (Martin Pitt)
  • Fix crash in GLib.find_program_in_path() (Martin Pitt) (#678119)
  • Revert “Do not bind gobject_get_data() and gobject_set_data()” (Martin Pitt) (#641944)
  • GVariant: Raise proper TypeError on invalid tuple input (David Keijser) (#678317)

Update:Just released 3.3.3.1 to fix a regresssion from the keyword escaping patch. It also escaped enum and flags names, but as they are translated to upper case they are never keywords.

A few weeks ago I wrote about my new role as an upstream QA engineer. I have now officially been in that role since June. Quite expectedly I had (and still have) some backlog from my previous Desktop engineer role, but I have had plenty of time to work on automatic tests and some test technology now. If you are interested in the daily details, you can look at the ramblings on my G+ page; in a nutshell I worked on integration tests for udisks2 (mostly upstream now), a mock polkit API, and a small enhancement of the scsi_debug kernel module. On the distro QA side I got the integration tests of udisks2, upower, PostgreSQL, Apport, and ubuntu-drivers-common working and added to our Jenkins autopkgtest runner, where they are executed whenever the particular package or any of its dependencies get updated. This already uncovered a surprising number of actual bugs, so I’m happy that this system starts being useful after the initial hump of getting the tests to run properly in that environment.

In that previous blog post I mentioned that Canonical will hire a second person for an upstream QA engineer role. I am pleased that the job posting is now online, so if you are familiar with how the Linux plumbing and desktop stacks work, are frantic about testing, like to work with the Linux, plumbing, GNOME, and other FOSS communities, know your way around jhbuild, Jenkins, and similar technologies, and would like to explore new possibilities like applying static code checking or creating APIs to fake hardware, please have a look at the role description! Please feel free to contact me on IRC (pitti on Freenode) or by email if you have further questions about the role.

I just released PyGObject 3.3.2, (almost) in time for tomorrow’s GNOME 3.5.2 release. No API breaks or new features this time, just lots of bug fixes and some minor API completions. My personal favorite is making closure calls work with GVariant arguments, which I finally figured out after over half a year; this finally unblocks making GDBus fully introspectable with not too much additional work, only that in the meantime dbus-python was ported to Python 3 so that the need for it is actually a lot smaller now.

Thanks to all contributors!
