[gentoo-dev] [RFC] Timeline for Python 3.9 switch and Python 3.7 removal

[gentoo-dev] [RFC] Timeline for Python 3.9 switch and Python 3.7 removal

[Michał Górny]

Hi,

I'd like to discuss a rough timeline for switching the default
PYTHON_TARGETS to python3.9.

According to the upstream release schedule [1], the last bugfix release
is planned for May.  Afterwards, upstream will release only security
fixes.  At the same time, our rough current schedule [2] suggests that
we'll start last-riting stuff May 1st, so the 3.7 target would be
removed in 15-30 days.

Do you think 2021-06-01 would be a reasonable planned switchover date?

So you are saying we will start masking packages may 1st and we will
drop 3.7 targets 30 days later (june 1?)

(I felt like this was a bit ambiguous?)

The target will be removed when all packages not supporting 3.8 are
removed, so the exact time depends on what package will remain
in ::gentoo at May 1st.

Ideally, all packages will be ported by then and the only packages to
mask will be backports.  For these, I use the shorter 14 day period. 
However, if we have to remove some real packages I'll use 30 days
instead.
