ctypes: Remove misleading comment about tuple support in _as_parameter_ and add regression test #142174
Closed as not planned
Description
Bug report
Bug description:
Modules/_ctypes/callproc.c contained a comment (marked XXX) stating that as_parameter
allows constructing arbitrary tuples and passing them, describing this convention as "dangerous".
Analysis confirms that
ctypes
does not support returning tuples from as_parameter for default conversions. Attempting to do so raises a "TypeError" (wrapped in an ArgumentError), meaning the described security risk does not exist in the current codebase.
CPython versions tested on:
