Description Lumír Balhar 2019-08-06 12:43:08 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 pychart'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 pychart.
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'.

This one is going to be a bit painful to lose. I don't really see any replacement, and upstream is long dead. Perhaps this is one we could keep for a while (or have someone try to port to Python 3)?

Comment 4 Miro Hrončok 2019-08-14 22:43:18 UTC

Petr might know some alternative.

This indeed seems long dead. All upstream web pages give 404 and the package even has Python 2.4 documentation as source. Not sure people want to spend energy on porting such thing, unless they would like to become the new upstream.

Comment 5 Petr Viktorin (pviktori) 2019-08-15 10:22:02 UTC

It's the first time I hear about this package.
How is it different from Matplotlib? (https://matplotlib.org/gallery.html)

I'm going to simply retire it and let the folks with broken deps either revive and port, or move to something else.

Comment 7 Lumír Balhar 2019-08-16 04:48:37 UTC

A better solution would be to orphan the package so somebody else would be able to take it. Could you please let maintainers of audit-viewer know that one of their dependencies is no longer available in Fedora?
