New issue 2930: memoryview(ctypes.Structure) does not produce the correct format string https://bitbucket.org/pypy/pypy/issues/2930/memoryview-ctypesstructure-does-not
mattip: The following passes on CPython, fails on PyPy (`mv.format` is `B`) ``` class Struct(Structure): _fields_ = [('a', c_int16)] Struct3 = 3 * Struct c_array = (2 * Struct3)( Struct3(Struct(a=1), Struct(a=2), Struct(a=3)), Struct3(Struct(a=4), Struct(a=5), Struct(a=6)) ) mv = memoryview(c_array) assert mv.format == 'T{<h:a:}' ``` The `memoryview` call goes to `_CData.__buffer__` in `lib_pypy._ctypes.basics.py`, which should not just call `buffer(self._buffer)` _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
