4 years ago Hi. I was hoping to grab shiboken2 and pyside2 and put them in Gentoo,
Oh, blessed news!
...but the test failures appear significant.
...oh, bugger. I must confess that I've never actually run these tests myself. The massive failures you've exhibited above are both edifying and terrifying – but probably also ignorable. I and the fine gentle(wo)men at the ::waebbl overlay can assure everyone here that the shiboken2, pyside2, and pyside2-tools ebuilds all behave as expected – and have for the past several years. In particular, ebuilds for:
- The several million-line PySide2-based BETSEE multiphysics biology simulator hosted at this overlay work perfectly well. There are no open issues there.
- The several million-line PySide2-based FreeCAD 3D parametric modeller hosted at
::waebblwork basically well, open issues notwithstanding.
Clearly, there's a critical disconnect between unit tests in the shiboken2 test suite and the actual real-world robustness of shiboken2. If I had to venture an uneducated guess, it would be that The Qt Company has expanded the shiboken2 test suite to cover future edge cases and feature requests not currently required by PySide2.
Nokia's original vision for shiboken was always as a general-purpose C++ -> Python binding generator deployed by a diverse ecosystem of downstream Python projects – not just PySide. That idyllic utopian vision never happened, of course. PySide2 is still the only downstream Python project to directly leverage shiboken2....to my limited knowledge.
The Qt Company would probably very much like it if multiple projects began requiring shiboken2, as the maintenance burden would then be somewhat shifted off their industrious shoulders and onto the volunteer open-source community as a whole. Ergo, hypothetical shiboken2 unit tests exercising features that PySide2 doesn't currently need but other downstream clients might.
Or maybe the shiboken2 test suite is just totally b0rked. It's hard to see that happening, because this is The Qt Company. All in all, I can only give a noncommittal shrug as depicted here in XML: </noncommittal_shrug>
You might try redirecting this issue to the upstream Qt bug tracker. Ask for Christian Tismer if you do. He's a jolly good Pythonista and always delighted to help the Linux community out.
Thanks for the detailed report all the same, @ZeroChaos-! Always fun to see a fellow DEFCONner lurk out of the shadows. :eyeglasses:
