Description Petr Viktorin (pviktori) 2020-02-27 14:47:46 UTC
Python 2 reached upstream end-of-life in January 2020. In Fedora Rawhide, it's now provided from the compat package `python27`.
Packages that only use Python 2 at build time, like 0ad, had a general exception to keep using it in Fedora 31. Now, the dependency should be removed.
It looks like need for python2 comes from a very old bundled version of mozjs.

If it's possible that the dependency won't be removed in Fedora 33. Please request a FESCo exception. You can refer to the exception for mercurial as an example: https://pagure.io/fesco/issue/2243
It's good to mention:

- What is the reason for the Python 2 build dependency?

- What are the upstream/community plans/timelines regarding Python 2?

- What is the guidance for porting the build 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?)

If you need anything from us, or something is unclear, please mention it here.

Should be fixed now. Was required only for an intermediate %check, but just
works with python3 apparently.

Comment 2 Miro Hrončok 2020-06-29 19:14:44 UTC
I still see:

BuildRequires:	python2

In https://src.fedoraproject.org/rpms/0ad/blob/master/f/0ad.spec

Comment 3 Ben Cotton 2020-08-11 13:11:12 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 33 development cycle.
Changing version to 33.

Comment 4 Miro Hrončok 2021-05-14 14:26:44 UTC
Can the BuildRequires on python2 be removed or it is needed?

Comment 5 Ben Cotton 2021-08-10 12:47:25 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 35 development cycle.
Changing version to 35.

Comment 6 Bruno Wolff III 2021-09-07 00:51:29 UTC
I tested building without a buildrequires on python2 with an f34 scratch build and it built successfully. I didn't test running it as I use rawhide for all of my stuff. There is an issue building on rawhide and f35 right now due to the change to python 3.10. That makes testing this there hard right now.

This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.
