As find_module has been deprecated since python 3.4: https://github.com/python/cpython/blob/05c28b08f6e2fc8782472b026c98a3fdd61a2ba9/Lib/importlib/_bootstrap.py#L1347 and warnings added in python 3.10: https://github.com/python/cpython/blob/f91dfdf5ff9f68a4b012e1b70ab9997c6dc1542d/Lib/importlib/_bootstrap.py#L764 to respect the PEP-451 specification : https://peps.python.org/pep-0451/ So, override the find_spec() method to display depreaction warnings if applicable. X-original-commit: 000ce83492d67febc8b45b902500d57304455d04 --- This commit should have been merged by odoo/odoo#128924, but has been wrongly ignored. This oversight has been detected due to a fix inside the `find_spec` method (odoo/odoo#145800) that couldn't be forward-ported. This commit is therefore the combinaison of those two patches and the removal of the depreacted `find_module` method. closes odoo/odoo#146205 X-original-commit: df63a8aede024f7d4423f80f270a4aa662150e3e Signed-off-by: Christophe Simonis (chs) <chs@odoo.com> Co-authored-by: Enric Tobella <etobella@creublanca.es> Co-authored-by: Christophe Simonis <chs@odoo.com>
