0.14.2: test/widgets/test_{battery,volume}.py, test/test_images{,2}.py fail

See original GitHub issue

During packaging 0.14.2 for Arch Linux, I’m again attempting to run the test suite. While it still hangs (#1130) in general, I have the following failures, some of which I have observed before:

qtile-0.14.2-check.txt

Quite a few of them fail because of test/data/svg/audio-volume-muted.svg, while the other variants of the same test work just fine!

I got that test working in .spec with cp %{buildroot}%{_bindir}/qtile-cmd ./bin/ where `.`` is it PyPI sdist root

dvzrvcommented, Feb 17, 2021

After a long discussion round on this topic on IRC, I have finally been able to figure out, why the tests are failing: It looks as if librsvg is required for the tests and most likely also during runtime of qtile, for the loading of svg files.

Unfortunately, none of the current dependencies pull in librsvg (not even optionally) and I wonder how it is pulled in in the CI environment, but my assumption is it is via gir1.2-gtk-3.0.

On Arch we don’t have e.g. an optional dependency on gtk3 (which would pull in librsvg) for python-gobject, indicating this similar link and meet the dependency.

I will add librsvg as a dependency for qtile for the time being and try to figure out an improvement for the python-gobject/gtk3 situation on Arch.

I have to admit, that even after sieving through cairo (which is somehow able to load svg via libpng), python-cairocffi, gdk-pixbuf and rebuilding half of it for good measure, I am not much closer to understanding where exactly librsvg is actually coming into play.
