[Python-Dev] Do we need port some extension modules to the modules directory?

2020-04-12 Thread Hai Shi 
Hi,
I notice some modules not in modules directory(for example: 
_warnings、marshal in python directory). Do we need port those modules to 
modules directory?
Sorry for my noisy info.

Bests Wishs,
Hai Shi

I strongly suspect the answer is "no." Modules which aren't in the
Modules directory are built directly into the Python executable. Using
your example of the _warnings module, note that in Makefile.pre.in
Python/_warnings.o is listed in the PYTHON_OBJS list (as are
Python/sysmodule.o and Python/marshal.o). This is evidence they are
built directly into the interpreter itself. Another is that at runtime
those modules have no __file__ attribute:

>>> import marshal
>>> marshal.__file__
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: module 'marshal' has no attribute '__file__'
>>> import sys
>>> sys.__file__
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: module 'sys' has no attribute '__file__'
>>> import _warnings
>>> _warnings.__file__
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: module '_warnings' has no attribute '__file__'

I have created the bpo, the pr and have the checks passing except that I need a 
NEWS.d entry
to make bedevere/news happy. I see the files have a special filename is that 
from an automatic
process of a tool I need to run?
