Hello everyone,
As of Python 3.8, python C extensions modules should not link to libpython,
unless they embed the interpreter in their code. Relevant upstream PR:
https://github.com/python/cpython/pull/12946
If your package links to libpython without requiring it, it won't be possible
to use the python3-debug binary with your python C extension, unless you
recompile the extension against it.
On Fedora Rawhide, there are at this point 144 packages linking to libpython,
many of those possibly without any need for it.
If your package links to libpython but it does not embed the interpreter, I
would like to ask you to unlink it. Usually the fix needs to be done at the
package's build system.
If you are not sure if your package links to libpython, a way to figure this
out is to inspect the code for the Py_Initialize and the Py_Finalize calls
[0]. If the code includes those calls, no action is required from your side. If
it does not, linking to libpython is not required.
I might mass file bugzillas at a later date, but I wanted to provide you the
heads up before that.

Fixed in rawhide. No need to inform upstream, because linking to
libpython was a local Fedora-specific patch anyway.
