Description Lumír Balhar 2019-08-06 11:43:03 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 chromium'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 chromium.
If you need anything from us, or something is unclear, please mention it here.

Thank you.

Chromium uses Python 2.7 in the build system.

They started to work on it recently - see https://bugs.chromium.org/p/chromium/issues/detail?id=942720

Until that's done, we will probably need some sort of exception if possible.
Comment 2 Lumír Balhar 2019-08-09 08:41:56 UTC 
Thanks for info. Don't forget to request an exception rather sooner than later.
Comment 3 Ben Cotton 2019-08-13 16:50:33 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

How exactly should I do this?
Comment 6 Lumír Balhar 2019-08-16 04:42:26 UTC 
Just open a Fesco issue with an explanation. For example: https://pagure.io/fesco/issue/2208
Comment 7 Miro Hrončok 2019-08-23 17:41:53 UTC 
see https://pagure.io/fesco/issue/2214
Comment 8 Miro Hrončok 2019-09-09 14:41:29 UTC 
Exception for chromium and python-psutil was granted.

Should we keep this open to eventually switch to Python 3?
Comment 9 Fedora Admin user for bugzilla script actions 2020-06-03 02:47:43 UTC 
This package has changed maintainer in the Fedora.
Reassigning to the new maintainer of this component.
