[Qgis-developer] Processing, Python 3 and Qt5

[Matthias Kuhn]

Hi,


A short update on porting plugins, python 3 and qt5. Today I had success
with running the processing tests on a py3/qt5 build. For the qgis
algorithms for which tests exist, there was just one single small
difference, where the py3/qt5 version offered an increased precision in
some statistics. Apart from this, everything (what is tested) works fine.


This is very good news. The py3/qt5 version of the plugin is produced by
the 2to3 update script and the update script therefore is doing a quite
good job already if it's able to migrate a complex plugin like processing.


Apart from this, it is yet another set of tests that prevents us from
introducing regressions while working on and updating the (python) API
in the migration process.


I'm looking forward to seeing more processing tests being introduced to
guarantee for a smooth transition.


All the best
