Seems unnecessary, most of the information already lives in `sys.modules`. We can just check that. There are a few changes in behaviour, but they seem minor: - if post_load fails, subsequent attempts to load the module will "succeed" - since we didn't remove/reload the module, a failure because of an incorrect post_load wasn't fixable, however it was possible to update the manifest Still seems like a wonky state to be in, and one we should ignore. Also remove the logging of the error: since we're re-raising as-is, the parent logs it with a traceback, so this is unnecessary and redundant. closes odoo/odoo#103933 Signed-off-by: Xavier Morel (xmo) <xmo@odoo.com>
