  "message": "Do not let the failed-import cache pin caller stacks\n\n``file_from_module_name`` caches failed imports in ``_mod_file_cache`` and\nraises the cached exception instance directly. Clearing ``__traceback__``\nright before the ``raise`` does nothing: Python attaches a fresh traceback\nto the object as it propagates, so the cache ends up holding the whole\ncaller stack, and every later cache hit re-pins a new one.\n\nRaise a copy instead, leaving the cached instance traceback-free.\n\nThe sibling strip on ``error\u003de.with_traceback(None)`` is kept: that one is\neffective, since the ``ImportError`` it clears is stored rather than raised.\n\nRefs #1780, refs #792\n",
