== Summary ==
Python 3 traditionally in Fedora was built with a shared library
libpython3.?.so and the final binary was dynamically linked against
that shared library. This change is about creating the static library
and linking the final python3 binary against it, as it provides
significant performance improvement, up to 27% depending on the
workload. The static library will not be shipped. The shared library
will continue to exist in a separate subpackage. In essence, python3
will no longer depend on libpython.
It seems that we have one group of people who prefer speed and another group
of people who prefer saved space.
Instead of focusing on a swiss-knife to satisfy everybody (which will not
work), can we have python3-static **and** python3-dynamic (*) packages and let
users decide which one will be installed and handle `/usr/bin/python3` using
`alternatives(8)`?
Then FESCO can "only" decide which one will be the default. And that is far
less controversial than deciding whether you will be forced to use a
time-saving or space-saving solution.
While I realize that this might actually be a clever thing to do, as the Python
maintainer, I don't want this for various reasons. Most importantly, it means we
need to to "support" twice that many Python interpreters.
It would also create a problem in RPM requirements.
Suppose a package need /usr/bin/python3.8 to be dynamically linked. How do I
express that? It would need to harcode some kind of
/usr/libexec/python3.8-dynamic? Would this require custom shebangs... etc.? I
really don't want to go that way. It's bad on RHEL 8 already, with
"platform-python".
Note that this is my personal opinion, not a team opinion.
I've confirmed this with the team. We are not going to do this, sorry.
We either do the change or don't. I'm personally fine with both options.
