[New-bugs-announce] [issue35722] disable_existing_loggers does not apply to the root logger

[Géry]

New submission from Géry <gery.ogam at gmail.com>:

In the logging package, the parameter disable_existing_loggers used in logging.config.dictConfig and logging.config.fileConfig does not apply to the root logger. More precisely, its disabled attribute remains unchanged (while it is set to True for non-root loggers). So it is either a bug or the documentation should be updated.

Illustration:

import logging.config

assert logging.getLogger().disabled is False
assert logging.getLogger("foo").disabled is False

logging.config.dictConfig({"version": 1})

assert logging.getLogger().disabled is False
assert logging.getLogger("foo").disabled is True
