[issue45459] Limited API support for Py_buffer

Serhiy Storchaka added the comment: ndim is not known before calling PyObject_GetBuffer(), so we will need a new API which combines PyObject_GetBuffer() and PyBuffer_New(). -- ___ Python tracker

[issue45438] inspect not capturing type annotations created by __class_getitem__

Serhiy Storchaka added the comment: The cause is that isinstance(list[int], type) returns True. It can cause bugs in other parts of the code which test for instance of type. For example: >>> types.resolve_bases((typing.List[int],)) (, ) >>> types.resolve_bases((list[int],)) (list[int],) >>>

[issue45459] Limited API support for Py_buffer

Christian Heimes added the comment: IIRC shape, strides, and suboffsets are all arrays of ndims length. We could optimize allocation if we would require users to specify the value of ndims and don't allow them to change the value afterwards. PyBuffer_New(int ndims) then would allocate view

[issue45247] [C API] Add explicit support for Cython to the C API

Serhiy Storchaka added the comment: I agree with Mark. Instead of exposing internal details in low-level API we should add more high-level API to satisfy concrete needs. It will give us more freedom of changing internals in future. -- nosy: +serhiy.storchaka

[issue45459] Limited API support for Py_buffer

Serhiy Storchaka added the comment: shape is a pointer to array of Py_ssize_t of size ndim. array and memoryview do a trick to avoid memory allocation, but _testbuffer.ndarray allocates it dynamically in the heap. We can add a small static buffer in Py_buffer to avoid additional memory

[issue45247] [C API] Add explicit support for Cython to the C API

STINNER Victor added the comment: > Rather than have Cython laboriously create a Python frame with fake code > object, etc., it would make much more sense for us to offer an API to insert > a "native" frame into the stack and update the line number. I agree with that. --

[issue45459] Limited API support for Py_buffer

STINNER Victor added the comment: Py_buffer.shape requires a Py_ssize_t* pointer. It's not convenient. For example, the array module uses: static int array_buffer_getbuf(arrayobject *self, Py_buffer *view, int flags) { ... if ((flags & PyBUF_ND)==PyBUF_ND) { view->shape =

[issue45247] [C API] Add explicit support for Cython to the C API

Mark Shannon added the comment: I disagree. All that is doing is locking in the current poor interface. We do need to extend the C API for these uses, yes. But we need an API that addresses Cython's needs directly and at a higher level. For example, Cython often wants to insert a frame into

[issue45459] Limited API support for Py_buffer

New submission from Christian Heimes : Currently all APIs related to Py_buffer are excluded from the limited API. It's neither possible to use Py_buffer from a C extension with limited API nor is it possible to define heap types with buffer support using the stable ABI. The lack of Py_buffer
