Hello,
we've been recently approached by a colleague from Red Hat working on
performance (CCed).
According to their testing, Fedora Python performance could be improved by ~15%
by building /usr/bin/python* statically with libpython*.a. That sounds like a
worthy thing to do.
https://bugzilla.redhat.com/show_bug.cgi?id=1749479
Since Python 3.8 Python extension modules are no longer linked to libpython.so
and we can do the following:
* build /usr/bin/python3(.8) statically with libpython*.a
* build and ship libpython3.8.so.1.0 for packages that "embed" Python
The change in the python3 package is trivial:
https://src.fedoraproject.org/rpms/python3/pull-request/133
However it can have serious impact on Python extension modules that are linked
to libpython3.8.so.1.0 by various "nonstandard" build mechanisms or by compiling
code for Python extension module and code that embeds Python into one file.
We will likely propose a Fedora 32 Change for this, however I'm opening this
topic for discussion before we do so.
Testing the proposed Pull Request with your code is also helpful. Let me know
how can we make that easier (e.g. if you want a Copr or a Fedora 30/31 python38
package with this change).
WDYT?
