#20083 closed Bug (worksforme)

Fix for #18985 makes it impossible to filter deprecation warnings

Description

The following does nothing on Python >= 2.7 because warnings are piped into logging since [44046e8a]:

warnings.filterwarnings(
    'error',
    r'django\.conf\.urls\.defaults is deprecated; use django\.conf\.urls instead',
    DeprecationWarning,
    r'django\.conf\.urls\.defaults')

That's a bit annoying.

Added test about error filterwarnings

Refs #20083.

Resolution: → worksforme
Status: new → closed

Looking at the source code of the warnings module, it seems that raising the exception precedes the showwarning call, hence routing through logging should not affect error filters. I've just added a test for this. But it may be that recent commits with addition of DeprecationWarning subclasses for Django deprecations has also helped.
