Re: [Cython] Failing test reimport_from_subinterpreter

OK, I finished analyzing the problem. It's a combination of: 1. the Sage wrapper around the Cython installer setting PYTHONPATH 2. the reimport_from_subinterpreter test failing if PYTHONPATH is set I'll open a PR quick. ___ cython-devel mailing list c

Re: [Cython] longintrepr.h issues with MinGW

If you care about MinGW, there is also this CPython issue which makes it basically impossible to compile any Cython extension on MinGW: https://bugs.python.org/issue11566 ___ cython-devel mailing list cython-devel@python.org https://mail.python.org/mai

Re: [Cython] Hooking tp_clear()

(reviving this thread after I thought about it some more...) As I mentioned in the original post, I want something like __dealloc__ but with access to a particular cdef attribute (representing a Python object). Since Python attributes of cdef classes may have been cleared by tp_clear, they can

[Cython] Reason for __Pyx_PyObject_Call2Args, __Pyx_PyObject_Call3Args

Is there any particular reason why Cython has specific code like __Pyx_PyObject_Call2Args, __Pyx_PyObject_Call3Args, ... And then there is even more complicated Python code in PyMethodCallNode generating something like __Pyx_PyObject_Call2Args for an arbitrary number of arguments. This could

[Cython] Working on METH_FASTCALL and vectorcall support

Hello, this is just to let you know that I'm planning to add support for functions/methods defined with METH_FASTCALL instead of METH_VARARGS on CPython 3.7. Once this is implemented, it will be fairly easy to use vectorcall (PEP 590) for cython_function_or_method. Jeroen. ___

[Cython] Empty defines of Py_TPFLAGS_METHOD_DESCRIPTOR?

Hello, What's the purpose of commit https://github.com/cython/cython/commit/8ac1a6a55fc44ff858cc367af556250a91f71d16 I can't think of any reasonable scenario where Py_TPFLAGS_METHOD_DESCRIPTOR would be defined differently than in CPython (i.e. with value 1<<17). This is an honest question,

[Cython] How to detect CyFunction?

Hi, I have a very technical question about Cython.Compiler.Nodes.DefNode: how can I know whether the instance represents a PyCFunction (built-in function) or a CyFunction (Cython function)? I've tried all the obvious conditions such as checking self.is_cyfunction, self.py_cfunc_node.binding and env
