[done for master / waiting for freecad 0.19 release] conda: python3.8 is coming

[looo]

As I just received the first PR's for python3.8 I thought it might be interesting for others to see the status of the freecad-related packages. I guess the migration won't introduce too much troubles and we will see a python3.8-freecad-build in early December.

Thanks for the 'play by play'!

The PR's for freecad came faster than expected... Btw.: this will not yet affect the 0.19_pre packages which are used for dmg/appimage. Only the more official package from conda-forge will be build with py3.8 + py3.7. So we are able to do some testing before updating the 0.19_pre-feedstock.

How to install?
You're amazing looo.
Noticed this as well, related to the enhancements idea: https://www.python.org/downloads/release/python-380/

FreeCAD itself is not done yet, some homework is necessary:

It's nearly done. A working version is available via freecad/label/testing channel. Some changes for pyside2 need to be backported (or use qt5.14 with pyside2 5.14). I will try to apply the patches to pyside5.13 with qt5.12.5 as conda-forge only builds lts versions of qt.

There are still some issues with py3.8:
time.clock was removed and should be replace according to: (There are some occurences in FEM)
https://stackoverflow.com/questions/585 ... python-3-8

And there is still a occt7.4 issue which I have no idea how to solve:

Nice!

P.S. As for FreeCAD 0.19 release, i am guessing that should happen around April, it would be good if packages would be tested for a month or two and wouldn't change before doing a release.

Sure. If python 3.8 and occt7.4 still have issues I guess we should go for py3.7 and occt7.3.

But still I believe it's important to try to go with the latest available packages to provide feedback.

Didn't check and i will just ask, is this already done for the (0.19) binaries? If not it would be great if it could be done ASAP. As doing it a few days before release is likely a bad idea.

sure. appimage and dmg are already using py38 / occt7.4.
