Comment (by claudep):
After some thinking, I think there is a small flaw in the current Django
logging config system. The LOGGING config in global_settings.py is
overriden by any custom settings LOGGING. When we update LOGGING in
global_settings, any upgraded project cannot take advantage of newer
features in the LOGGING config.
My proposal would be:
* Add DEFAULT_LOGGING in global_settings.py (with current LOGGING as
content). This is *not* supposed to be overriden by project's settings.py
(we can even imagine put it somewhere else, django.utils.log comes to
mind). By default, global_settings.py LOGGING would be empty. We can still
let the current content in project template LOGGING.
* When configuring LOGGING (`django.conf.__init__.py`), first feed
DEFAULT_LOGGING to the config function, then, if LOGGING is not empty,
feed LOGGING to the config system.
Here are the possible scenarios:
* If the user has set `disable_existing_loggers` to True in his project's
LOGGING, nothing has changed for him. He's still in complete control of
logging in his project.
* If the user has no LOGGING in his settings, the situation is unchanged,
Django default logging is configured.
* If the user has set `disable_existing_loggers` to False in LOGGING
(which is currently the default in the project template), then Django
default logging is configured, and the user custom LOGGING is *added* to
the Django default configuration.
This latest point is where we really gain from the current situation. We
don't have to fiddle any more with the logging setup code.
I may be missing something in my reasoning. Comments welcome!
