Justin Capella added the comment: Becca were you still interested in this issue? Anyone agree the unit test seems to have a bug if that is intended behavior? Is there a better forum for discussion about design/behavior, maybe the more generic issue of GenericPyCData_new using tp_alloc inste

[issue38860] GenericPyCData_new does not invoke new or init

Justin Capella added the comment: It might make sense that CSimpleData types do not call init, which makes sense for _fields_ but it doesn't make sense to offer subclassing (of Structure) and not use the subclass, instead creating a type of the same name. That test case is bugged, missing an

Rebecca Morgan added the comment: Looking at the test case 'test_from_buffer_copy' here: https://github.com/python/cpython/blob/master/Lib/ctypes/test/test_frombuffer.py This suggests the failure to call init in this instance is expected behavior (similarly for from_buffer), unlike e.g. the c

[issue38860] GenericPyCData_new does not invoke new or init

New submission from Justin Capella : When subclassing the ctypes.Structure class, __new__ and __init__ are not invoked when using the inherited classmethod from_buffer_copy to create the object. I think this is because tp_alloc is ultimately used by GenericPyCData_new when creating the objec
