Description: Ctypes currently produces wrong pep3118 type codes for several types. E.g. memoryview(ctypes.c_long()).format gives "' endian specification in the struct syntax also turns on the "standard size" mode, which makes type characters have a platform-independent meaning, which does not match with the codes used internally in ctypes. The struct module format syntax also does not allow specifying native-size non-native-endian items. This commit adds a converter function that maps the internal ctypes codes to appropriate struct module standard-size codes in the pep3118 format strings. The tests are modified to check for this. Example of the current problem in practice: >>> import numpy, ctypes >>> numpy.asarray(memoryview(ctypes.c_long(42))) /usr/lib64/python3.5/site-packages/numpy/core/numeric.py:482: RuntimeWarning: Item size computed from the PEP 3118 buffer format string does not match the actual item size. return array(a, dtype, copy=False, order=order) Traceback (most recent call last): File "", line 1, in File "/usr/lib64/python3.5/site-packages/numpy/core/numeric.py", line 482, in asarray return array(a, dtype, copy=False, order=order) ValueError: setting an array element with a sequence. struct format string syntax bpo-10746 https://bugs.python.org/issue10746
