umockdev 0.2.2 released

I did a 0.2.2 maintenance release for umockdev to fix building with Vala 0.16.1, gcc 4.8 (the changed sizeof behaviour caused segfaults), and current udev releases (umockdev-record stumbled over the new “link priority” fields of udevadm). There are also a couple of bug fixes, but no new features.

New fatrace released, Debian package coming

Paul Wise poked me this morning about uploading fatrace (“file access trace”, see the original announcement for details) to Debian, thanks for the reminder!

So I filed an Intent To Package, and will upload it in a few days, unless some discussion evolves.

I also took the opportunity to do some modernization: The power-usage-report script now uses the current PowerTop 2.x instead of the old 1.13, uses Python 3 now, and includes the “process device activity” in the report. I released this as 0.5. The actual fatrace binary didn’t change its behaviour, it just got some code optimizations; thanks to Yann Droneaud for those.

Urgent PostgreSQL security updates for Debian/Ubuntu

PostgreSQL just released security updates. 9.1 (as found in Debian testing and unstable and Ubuntu 11.10 and later) is affected by a critical remote vulnerability which potentially allows anyone who can access the TCP port (without credentials) to corrupt local files. If your PostgreSQL database exposes the TCP port to any potentially untrusted location, please shut down your servers and update now!

PostgreSQL 8.4 for Debian stable (squeeze) and Ubuntu 8.04 LTS and 10.04 LTS also got an update, but these are much less urgent.

Debian and Ubuntu advisories for all stable releases, as well as Debian testing are going out as we speak. The updates are already on security.debian.org and security.ubuntu.com.

I also uploaded updates for Debian unstable (8.4, 9.1, and 9.2 in experimental) and the Ubuntu backports PPA, but it will take a bit for these to build as we don’t have embargoed staging builds for those. Christoph updated the apt.postgresql.org repository as well.

Warning: If you use the current Ubuntu raring Beta-2 candidate images, you will still have the old version. So if you do anything serious with those installations, please make sure to upgrade immediately.

Update: Debian and Ubuntu security announcements have been sent out, and all packages in the backports PPA are built.

Please see the official FAQ if you want to know some more details about the nature of the vulnerabilities.

python-dbusmock 0.6 released

I just pushed out a new python-dbusmock release 0.6.

Calling a method on the mock now emits a MethodCalled signal on the org.freedesktop.DBus.Mock interface. In some cases this is easier to track than parsing the mock’s log or using GetMethodCalls. Thanks to Lars Uebernickel for this.

DBusMockObject.AddTemplate() and DBusTestCase.spawn_server_template() can now load local templates from your own project by specifying a path to a *.py file as template name. Thanks to Lucas De Marchi for this feature.

I also wrote a quite comprehensive template for systemd’s logind. It stubs out the power management functionality as well as user/seat/session objects, and is convincing enough for loginctl. Some bits like AttachDevice is missing, as this sounds unlikely to be required for D-BUS mock tests, but please let me know if you need anything else.

The mock processes now terminate automatically if their connected D-BUS goes down, as advertised in the documentation.

You can get the new tarball from Launchpad, and I uploaded it to Debian experimental now.

Enjoy!

PyGObject 3.7.92 released

I just released a new PyGObject for GNOME 3.7.92. This fixes a couple of crashes and marshalling errors again, but most importantly got a change to automatically mute the PyGIDeprecationWarnings for stable versions. Please run pythonX.X with the -Wd option to still be able to see them.

We got through all our bugs that were milestoned for GNOME 3.8 and don’t want to or plan to introduce any major behavioural change at this point, so barring catastrophes this is what will be in GNOME 3.8.0.

Thanks to all contributors!

  • Fix stack smasher when marshaling enums as a vfunc return value (Simon Feltman) (#637832)
  • Change base class of PyGIDeprecationWarning based on minor version (Simon Feltman) (#696011)
  • autogen.sh: Source gnome-autogen to fix out of source builddir (Alban Browaeys) (#694889)
  • pygtkcompat: Make gdk.Window.get_geometry return tuple of 5 (Simon Feltman)
  • pygtkcompat: Initialize hint to zero in set_geometry_hints (Simon Feltman)
  • Remove incorrect bounds check with property helper flags (Simon Feltman)
  • Fix crash when setting property of type object to an incorrect type (Simon Feltman) (#695420)
  • Remove skipping of object property tests (Simon Feltman) (#695420)
  • Give more informative error when setting property to incorrect type (Simon Feltman) (#695420)

PyGObject 3.7.91.1 released

I just found out that PyGObject 3.7.91 as released yesterday breaks GEdit plugins. I just pushed out 3.7.91.1 to unbreak this again, sorry about that!

Automatically generating documentation from GIR files

Many libraries build a GObject introspection repository (*.gir) these days which allows the library to be used from many scripting (Python, JavaScript, Perl, etc.) and other (e. g. Vala) languages without the need for manually writing bindings for each of those.

One issue that I hear surprisingly often is “there is zero documentation for those bindings”. Tools for building documentation out of a .gir have existed for a long time already, just far too many people seem to not know about them.

For example, to build Yelp XML documentation out of the libnotify bindings for Python:

  $ g-ir-doc-tool --language=Python -o /tmp/notify-doc /usr/share/gir-1.0/Notify-0.7.gir

Then you can call yelp /tmp/notify-doc to browse the documentation. You can of course also use the standard Mallard tools to convert them to HTML for sticking them on a website:

  $ cd /tmp/notify-doc
  $ yelp-build html .

Admittedly they are far from pretty, and there are still lots of refinements that should be done for the documentation itself (like adding language specific examples) and also for the generated result (prettification, dynamic search, and what not), but it’s certainly far from “nothign”, and a good start.

If you are interested in working on this, please show up in #introspection or discuss it on bugzilla, desktop-devel-list@, or the library specific lists/bug trackers.

PyGObject 3.7.91 released.

I just released a new PyGObject for GNOME 3.7.91. This brings some marshalling fixes, plugs tons of memory leaks, and now raises a Python DeprecationWarning when your code calls a method which is marked as deprecated in the typelib. Please note that Python hides them by default, so if you are interested in those you need to run python with the -Wd option.

Thanks to all contributors!
