Description Lumír Balhar 2019-08-06 11:42:41 UTC
Python 2.7 will reach end-of-life in January 2020, over 9 years after it was released. This falls within the Fedora 31 lifetime.
Packages that depend on Python 2 are being switched to Python 3 or removed from Fedora: https://fedoraproject.org/wiki/Changes/F31_Mass_Python_2_Package_Removal#Information_on_Remaining_Packages
Python 2 will be retired in Fedora 32: https://fedoraproject.org/wiki/Changes/RetirePython2

To help planning, we'd like to know the plans for inkscape's future. Specifically:


- What is the reason for the Python2 dependency? (Is it software written in Python, or does it just provide Python bindings, or use Python in the build system or test runner?) 

- What are the upstream/community plans/timelines regarding Python 3?

- What is the guidance for porting to Python 3? (Assuming that there is someone who generally knows how to port to Python 3, but doesn't know anything about the particular package, what are the next steps to take?)


This bug is filed semi-automatically, and might not have all the context specific to inkscape.
If you need anything from us, or something is unclear, please mention it here.

Thank you.

The next release should support Python 3.

This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to 31.

Comment 4 Lumír Balhar 2019-08-16 09:01:23 UTC
The current plan is to remove packages with dependency on Python 2 from Fedora 32 in the middle of November 2019. If you want to keep your package in Fedora after that date and you cannot port it to Python 3 yet, you need to request a FESCo exception for the package and all its Python 2 dependencies (even transitive) [1]. If you don't want to maintain it anymore, please orphan the package.

If you're considering filing the exception request, let us know. We can help (for example, we can help find all the dependencies).

> The next release should support Python 3.

Excellent news. Do you have some links or ETA? Can we update to that version in rawhide now, even if not yet released, or there is nothing testable at this point yet?

Comment 6 Gwyn Ciesla 2019-08-26 16:10:45 UTC
Nothing yet. I've been told "soon".

Comment 7 Miro Hrončok 2019-08-26 17:01:14 UTC
I think that inkscape would get an exception to continue running on Python 2. Poritngdb shows it needs:

uniconvertor
python2-lxml
python2-scour
python2-numpy

Are any of those optional?

Comment 8 Gwyn Ciesla 2019-08-26 17:05:14 UTC
Possibly. I'm testing a git checkout of master, and if it works that moots the whole thing.

Comment 9 Gwyn Ciesla 2019-08-27 13:43:27 UTC
Master works. Do we want this in f31 or is f32 sufficient?

Comment 10 Miro Hrončok 2019-08-27 13:53:51 UTC
Considering the beta freeze, I would not put this to f31 now.

Comment 11 Gwyn Ciesla 2019-08-27 13:59:45 UTC
Agreed.
