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.

bpo-35673: Add a public alias for namespace package __loader__ attribute ( #29049 )
...
Rename namespace package __loader__ class to be public.
Make the old name, i.e. _NamespaceLoader, an alias for the public name, for backward compatibility.

bpo-42137: have ModuleType.__repr__ prefer __spec__ over module_repr() (GH-24953)
...
This is to work towards the removal of the use of module_repr() in Python 3.12 (documented as deprecated since 3.4).
