My point here is that I want to keep Python 2 much longer (for developers who
unfortunately still need to support it, e.g. for RHEL 7) than I'd like to keep
allowing packages to buiid with it.
May I suggest "don't bother". The ongoing requirement of python2 for
RPM in RHEL 7 should not hinder any other work. Tools published using
python 2 should, in almost all cases, be upgraded to to python 3 for
stability and supportability. I'm particularly staring at tools in
EPEL, such as awscli and ansible.
Similarly there are no macros for Python 3.5 or 3.7 in Fedora, but
the Pythons
are available.
And it's a problem for people who use EPEL and who use Amazon Linux 2,
which chose to jump to python 3.7 as the base for python 3 rather than
python 3.6 as RHEL 7 and RHEL 8 did.
I'd also like to stop worrying about compatibility of the Python
RPM generators
with Python 2 packages (it gets extremely hard to test, as the real word
scenarios in Fedora are currently almost non-existent).
Yeah, especially when you start trying to chase down the dependency
chains. Don't get me started on the circular dependencies for subtly
distinct versions of "sphinx" expanding those dependency chains.Or get
me going on the unwelcome and unnecessary "bundling of three distinct
AWS published modules into the "s3transfer" package.
