New Revision: 46689
Modified:
python/trunk/Lib/ctypes/test/test_structures.py
python/trunk/Modules/_ctypes/cfield.c
Log:
Convert CFieldObject tp_members to tp_getset, since there is no
structmember typecode for Py_ssize_t fields. This should fix some of
the errors on the PPC64 debian machine (64-bit, big endian).
Assigning to readonly fields now raises AttributeError instead of
TypeError, so the testcase has to be changed as well.
