  • _as_parameter_ not implemented for CFuncPtr in ctypes (see as_parameter not implemented for CFuncPtr in ctypes)
  • Debug issue with ctypes\test\test_frombuffer.py#test_abstract
  • Marshaling of strings when no argtypes is provided is incorrect. This is seen in ctypes\test\test_functions.py test_stringresult.
  • test_memfunctions.py is not working correctly - test_memmove and test_string_at are not working
  • test_memmove and test_string_at are not working
  • Issue in ctypes\test\test_strings.py

FAILED (failures=7)

  • ctypes long double tests are failing on Linux. .NET is using double type for 'g' type format (long double). Long double on Windows is apparently the same as the double type in .NET, but on Linux, long double is a 128bit floating point type.

  • ctypes implementation does not support gcc packing of bitfields. ctypes\test\test_bitfields.py is failing because with gcc, bitfields are not padded like on Windows with cl. So, type sizes are different on Linux and Windows when dealing with bitfields.

  • ctypes Structure from_buffer needs to have overload that accepts IBufferProtocol
class Little(LittleEndianStructure):
            _fields_ = [("a", c_uint32, 24),
                        ("b", c_uint32, 4),
                        ("c", c_uint32, 4)]
b = bytearray(4)
x = Little.from_buffer(b)
x.a = 0xabcdef
x.b = 1
x.c = 2
self.assertEqual(b, b'\xef\xcd\xab\x21')

We get a TypeError on this right now because we only have a from_buffer implementation that takes an array type. We need to support IBufferProtocol (and check that it is not ReadOnly)

  • test_win32.py is failing, it is only valid on 32-bit. stdcall calling needs to be looked at.
  • ctypes tests need to be debugged on macOS
