Description Petr Viktorin (pviktori) 2020-02-26 16:22:13 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 eclipse-pydev, had a general exception to keep using it in Fedora 31. Now, the dependency should be removed.
Let us know if you need any help investigating or removing the dependency. (There are dozens of packages like this, so we didn't investigate this one thoroughly. We assume you know the package best.)

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.
Comment 1 Miro Hrončok 2020-02-26 16:24:39 UTC 
I've tried to fix this couple months back but it got caught in a modular crossfire: https://src.fedoraproject.org/rpms/eclipse-pydev/pull-request/1
Comment 2 Petr Viktorin (pviktori) 2020-02-27 11:41:50 UTC 
I don't know of a good way to query modular content, so changes/removal of Python 2 will not be announced/coordinated with individual module packagers.

So if this gets moved to a module, please monitor Fedora changes related to Python 2.
Comment 3 Miro Hrončok 2020-02-27 12:30:25 UTC 
Anyway the spec on master has:

	
%if 0%{?fedora} < 32
# Cython for python 2 was removed in F32+
BuildRequires:    python2-devel
BuildRequires:    python2-Cython
%endif


It just hasn't been built successfully yet.
