Description Lumír Balhar 2019-08-08 12:29:47 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 timeline'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 timeline.
If you need anything from us, or something is unclear, please mention it here.

Thank you.

Emailed upstream.

It looks that the solution here is okay and the newest build of timeline package doesn't depend on Python 2. But I am afraid that the new versioning schema is not right. In my opinion, the ".beta.e73292739f1c" part should be in the Release tag before "%{?dist}" and not after it.

This might be the reason why the newest version of timeline is not available in the rawhide repository.

Quite right, thank you. Fixed.
