Description Lumír Balhar 2019-08-06 10:08:57 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 sx'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 sx.
If you need anything from us, or something is unclear, please mention it here.

Thank you.

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

Comment 2 Lumír Balhar 2019-08-15 07:41:50 UTC

Please answer the above questions. If you don't, the package can be orphaned: https://fedoraproject.org/wiki/Changes/F31_Mass_Python_2_Package_Removal#Information_on_Remaining_Packages

If you need any information or help, or if you need some more time, please let us know.

- 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?) 
It was tested only under python2 AFAIK.

- What are the upstream/community plans/timelines regarding Python 3?
That's a good question. The package is not used much any more and I'm not sure it is worth the effort to be ported to python3.

- 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?)
No idea TBH.

I'll check with the main developer of the package and see what are the plans and see what the actual code does with python3.

Comment 4 Lumír Balhar 2019-08-23 15:10:58 UTC

Thank you for the info. This package is a leaf (nothing depends on it in rawhide).

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, and nothing in Fedora uses it, you can retire it or just remove the Python 2 part from it (subpackage, module, bindings, etc.).

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

Comment 5 Petr Viktorin (pviktori) 2019-11-01 17:16:49 UTC

Any news on this?
The default will be to remove the package in mid-November.
