Miro Hrončok ae1965ccb4 bpo-45703: Invalidate _NamespacePath cache on importlib.invalidate_ca… (GH-29384) ... Consider the following directory structure: . └── PATH1 └── namespace └── sub1 └── __init__.py And both PATH1 and PATH2 in sys path: $ PYTHONPATH=PATH1:PATH2 python3.11 >>> import namespace >>> import namespace.sub1 >>> namespace.__path__ _NamespacePath(['.../PATH1/namespace']) >>> ... While this interpreter still runs, PATH2/namespace/sub2 is created: . ├── PATH1 │ └── namespace │ └── sub1 │ └── __init__.py └── PATH2 └── namespace └── sub2 └── __init__.py The newly created module cannot be imported: >>> ... >>> namespace.__path__ _NamespacePath(['.../PATH1/namespace']) >>> import namespace.sub2 Traceback (most recent call last): File "<stdin>", line 1, in <module> ModuleNotFoundError: No module named 'namespace.sub2' Calling importlib.invalidate_caches() now newly allows to import it: >>> import importlib >>> importlib.invalidate_caches() >>> namespace.__path__ _NamespacePath(['.../PATH1/namespace']) >>> import namespace.sub2 >>> namespace.__path__ _NamespacePath(['.../PATH1/namespace', '.../PATH2/namespace']) This was not previously possible.		2021-11-23 07:38:02 -08:00
