Severity: important
Hi!
While rebuilding the python related packages against the Python 3.15rc2
version we found that python-loky fails to build from source [1].
Almost all the resource tracker tests fail, and this can be fixed by
applying the upstream resource_tracker fix (5c28e6c) [2].
I've applied the upstream fix in the sandbox [3] to verify that it
builds successfully, please consider applying the patch to support the
upcoming 3.15 version.
Setting the severity to important for now. Once Python 3.15 is released,
it will be added to python3-defaults and this bug will become release
critical.
Happy hacking,
