[issue34107] root.warning('msg') output format modified by logging.warning('msg')

[Vinay Sajip]

This behaviour is as expected. If no handlers are configured for logging, an internal "handler of last resort" is used, with just the message output. See:

https://docs.python.org/3/howto/logging.html#what-happens-if-no-configuration-is-provided

If you call logging.warning(...), and if no handlers are configured, then basicConfig() is internally called to set up a handler with a basic format string. See:

https://docs.python.org/3/library/logging.html#logging.log

So, what you've described is as it should be.
