Ah, there is a way to create non-contiguous buffers.
>>> b = bytes(range(16))
>>> m = memoryview(b)
>>> m[::2].c_contiguous
False
> PyBUF_SIMPLE enforces contiguity.
Then contiguousity check in getbuffer() in Python/getargs.c is redundant. And in most cases the use of _PyBuffer_Converter() and PyObject_GetBuffer() could be replaced by the use of "y*" and "w*" format units. |
