#14264 closed Bug (fixed)

settings.configure has undocumented differences from using a settings module

Description

Calling django.conf.settings.configure bypasses the Settings class in that module entirely (in favor of UserSettingsHolder), thereby bypassing all of Settings.init. This makes it subtly but occasionally critically different: globs in INSTALLED_APPS are not processed, the os.environ timezone is not set, and there is no friendly string-conversion-to-tuple for settings like TEMPLATE_DIRS.

Not setting os.environ timezone is documented and correct: settings.configure implies that you are in control of your environment and may be using Django as a piece of a larger system, Django should not go messing with the environment.

The other two differences are oversights and should be fixed.

Has patch: set

A patch that refactors the Settings classes a bit, gets rid of the need for a BaseSettings class, and makes it so that the UserSettingsHolder class uses the same code paths for some post-processing of settings.

Patch needs improvement: set

Please don't call the method initialize but load (or similar), the ambiguity to __init__ is odd. Other than that this looks good to me.

Both the INSTALLED_APPS globs and string-to-tuple conversion have been deprecated, but calling configure() now also doesn't properly initialize the logging configuration from the settings LOGGING and LOGGING_CONFIG values. This can be fixed with a simple patch, which I've attached.
