Hi!
While rebuilding the python related packages against the Python 3.15rc1
version we found that python-mitogen fails to build from source [1].
I found that the fix had already been done upstream with Commit 983c7fa
[2].
I applied the upstream fix in the sandbox [3] to be able to build the
packages that depend on python-mitogen, please consider applying the
patch to support the upcoming 3.15 version.
Happy hacking,

Subject: mitogen: Python3.15 support
This excludes Ansible + Python 3.15, because it requires Ansible 15 which has
not had any release yet.
