[issue33802] Regression in logging configuration

[Steap]

Steap  added the comment:

It seems like this regression has not completely been fixed: there are still 
issues with "None":

$ python3.6 -c 'import configparser; configparser.ConfigParser(defaults={"a": 
None})'

$ python3.7 -c 'import configparser; configparser.ConfigParser(defaults={"a": 
1})'

$ python3.7 -c 'import configparser; configparser.ConfigParser(defaults={"a": 
None})'
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python3.7/configparser.py", line 638, in __init__

  File "/usr/lib/python3.7/configparser.py", line 1216, in _read_defaults

  File "/usr/lib/python3.7/configparser.py", line 1182, in _validate_value_types
raise TypeError("option values must be strings")
TypeError: option values must be strings

Should "None" not be used, or should this bug be reopened?

[issue20868] Lib/test/test_socket.py: skip testGetServBy if /etc/services is not found

[Steap]

Steap added the comment:

I did not know that /etc/services is not always used :/

The main issue is that when you run the test suite in a chroot (to do "pure" 
builds) or in a network sandbox (for other functions). I get the following 
errors:

==

[issue20868] Lib/test/test_socket.py: skip testGetServBy if /etc/services is not found

[Steap]

New submission from Steap:

In Lib/test/test_socket.py, testGetServBy calls socket.getservbyname(), which 
needs /etc/services (see "man getservbyname"). If this file is not found, the 
test fails instead of being skipped.

The attached patch was written against the latest revision of the Mercurial 
repository. It might be worth applying it for every currently supported version 
of Python.
