[Python-Dev] Windows - rebuilding grammar files

[Abdur-Rahmaan Janhangeer]

Greetings list,

On windows i want to play with the grammar file, but according to this
article :

> For Windows, there is no officially supported way of running pgen.
However, you can clone my fork
 and run
build.bat --regen from within the PCBuild directory.

But i don't want to work from his fork. Is there an official way of
regenerating
the files? I just want to have my own keywords. As far as i've understood,
rebuilding won't do it.

Yours,

Abdur-Rahmaan Janhangeer

[Python-Dev] Re: Last call for comments on PEP 573 (Module State Access from C Extension Methods)

Hi all,

I think that PEP 573 is ready to be accepted, to greatly improve the 
state

of extension modules in CPython 3.9.

https://www.python.org/dev/peps/pep-0573/

It has come a long way since the original proposal and went through 
several

iterations and discussions by various interested people, effectively
reducing its scope quite a bit. So this is the last call for comments on
the latest version of the PEP, before I will pronounce on it. Please keep
the discussion in this thread.


I have received substantial private feedback, and I'll need to make 
another update to:


## Better separate C-API additions:[...]  from CPython implementation details:
## Clarify that ht_module is not inherited
## Specify what "defining class" means more rigorously


The update is here: https://github.com/python/peps/pull/1275

It also includes a more drastic change: it removes the MRO walker from 
the proposal.
Reflecting on the feedback, it became clear to me that a MRO walker, as 
it was described, won't give correct results in all cases: specifically, 
is a slot is overridden by setting a special method from Python code, 
the walker won't be able to find module. Think something like:

c_add = Class.__add__  # where nb_add uses the MRO walker
Class.__add__ = lambda *args: "evil"
c_add(Class(), 0)  # Exception: Defining type has not been found.

This can be solved, but it will need a different design and more 
discussion. I'd rather defer it to the future.
Meanwhile, extension authors can use their own MRO walker if they're OK 
with some surprising edge cases.

Hello! Happy new year!

Can we kill this list now? It's barely used, almost no send mails and
no replies...

Thanks,
