new a81cfb7ac98 Fix failing __doc__ usage in case of PYTHONOPTIMIZE=2
(#77013)
a81cfb7ac98 is described below
commit a81cfb7ac980d4b72a80765f076b51aa8fe124ad
Author: diederikvdv <[email protected]>
AuthorDate: Fri Nov 13 15:13:57 2026 +0100
Fix failing __doc__ usage in case of PYTHONOPTIMIZE=2 (#77013)
* Fix failing __doc__ usage in case of PYTHONOPTIMIZE=2
Handle case where __doc__ is None for description.
PYTHONOPTIMIZE=2 drops the docstrings, causing an Attribute error when
__doc__ is used
* Add test for loading v2026_10_30 version changes without docstrings
Compile the module with optimize=2, as python -OO / PYTHONOPTIMIZE=2 does,
and execute it. Without the guard on inspect.cleandoc(__doc__) this raises
AttributeError: 'NoneType' object has no attribute 'expandtabs'.
