Hello, I have been trying out PyPy for a new project currently, and I noticed that os.getppid() function is missing on PyPy for Windows:

Python 3.10.12 (af44d0b8114cb82c40a07bb9ee9c1ca8a1b3688c, Jun 15 2023, 15:42:22)
[PyPy 7.3.12 with MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>> import os
>>>> os.getpid()
10744
>>>> os.getppid()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'os' has no attribute 'getppid'

Is this expected ? If I understand this right, the official CPython documentation states that it has been available on Windows since v 3.2:
https://docs.python.org/3/library/os.html#os.getppid

I have verified that it is included in CPython 3.11 on Windows.

Also, if there is a documentation of similar differences from CPython, it could help new comers to PyPy avoid such surprises.

Finally, thank you for a performance oriented Python implementation :)

Is this expected ?

No. Thanks for raising the issue. By doing the equivalent of import nt; print(dir(nt)) and then putting the results in a set and doing cpython ^ pypy I see PyPy is missing these:

{'_statfields', 'stat_float_times', 'getlogin', 'getppid', '_getdiskusage', \
 '_getvolumepathname', '_getfileinformation'}

I added getlogin and getppid in 49bc362df366. FWIW, we do have a compatibility page but this issue was an unintended oversight.

Closing, please reopen or open a new issue if the fix does not do what it is supposed to.

Okay, thank you for a quick response & fix. I noticed the commit against branch/py3.9. May I know which upcoming binary build (Python 3.10+) can I expect to include this fix ?

I merged the fix into py3.10 too. Assuming it builds, you should be able to download a nightly build tomorrow from https://buildbot.pypy.org/nightly/py3.10/ (check the dates, you want a build from Nov 1 up).

Alright, I'll do that. Thanks so much again.
