Description Lumír Balhar 2019-08-08 11:44:37 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 did'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 did.
If you need anything from us, or something is unclear, please mention it here.

Thank you.

Thanks for the reminder.

It's a command line tool written in Python.
It also provides a python module 'did'.

Migration planned in September 2019.

There is one larger pull request which would be good to merge
before the migration [1]. Otherwise no blockers. Any help welcome.

The only missing python3 dependency is nitrate: BZ#1738106
Martin Zeleny is already working on migration: BZ#1727936
Comment 3 Ben Cotton 2019-08-13 16:57:39 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

Comment 5 Lumír Balhar 2019-08-20 14:11:41 UTC 
Thank you for the info.

Just FYI:
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 6 Miro Hrončok 2019-09-22 11:30:13 UTC 
Automation has figured out the package is retired in Fedora 31.

If you like it to be unretired, please open a ticket at https://pagure.io/releng/new_issue?template=package_unretirement
