bpo-36974: PEP 590 #13185

jdemeyer · 2019-05-08T08:34:08Z

Implementation of PEP 590 by Mark Shannon and Jeroen Demeyer.

CC @encukou @markshannon

https://bugs.python.org/issue36974

…ctions Test functions are renamed to reflect the C API they're testing.

encukou · 2019-05-29T14:29:38Z

I went through the code, and made a few small changes. Do they look OK to you?

jdemeyer · 2019-05-29T15:04:52Z

I don't agree with 7536e69 for two reasons:

I tried to use Py_EnterRecursiveCall exactly where the old code also did that. The old implementation of _PyObject_FastCallDict didn't call Py_EnterRecursiveCall in the fastcall case and I don't see why it should do that now.
I want that _PyObject_FastCallDict behaves exactly the same as _PyObject_Vectorcall except for the way how keyword arguments are passed. And _PyObject_Vectorcall doesn't call Py_EnterRecursiveCall.

jdemeyer · 2019-05-29T15:10:30Z

Lib/test/test_capi.py

+        from types import MethodType
+        from functools import partial
+
+        def vectorcall(func, args, kwargs=None):


If you want to set a default for kwargs, it should be kwargs={}.

jdemeyer · 2019-05-29T15:12:26Z

Lib/test/test_capi.py

+    def test_vectorcall(self):
+        # Test a bunch of different ways to call objects:
+        # 1. normal call
+        # 2. vectorcall


It would be good to fix this comment, as you're adding a new way of testing the call.

jdemeyer · 2019-05-29T15:15:53Z

No further comments.

encukou · 2019-05-29T15:36:00Z

I'm not entirely convinced on the recursivecall, but it's probably OK to leave out. I'm out for a couple of hours. Could you push a revert and your suggested changes to get the CI going?

Oh! gdb integration is broken, since it seems to look for _PyCFunction_FastCallDict/_PyCFunction_FastCallKeywords by name.

All buildbots are green now.

Thank you, @jdemeyer and @markshannon, for putting this together!
There are follow-up PRs linked from the issue. Not sure if I can get them into Python 3.8, unfortunately – but the main part, the external API, is there.

Docs should come in early beta.

Petr, thank you for reviewing and merging and in particular fixing the buildbot failure.

About follow-ups:

#13498 would be good to merge, as it's part of the specification.
#13460 is pretty trivial, so why not? It speeds up functools.partial (which is often used as a building block for other classes).
#13464 should get a decision either way (merge or close), it makes no sense to wait until 3.9

The others are less important and can wait.

If you want to set a default for kwargs, it should be kwargs={}.
