./manage runserver --nostatic still doesn't return a traceback

[Michael]

Maybe its regression, related to: https://code.djangoproject.com/ticket/27522:

Its a ligit error, just hidden by --nostatic

It's WIP

Opened a new PR from the previous one: ​https://github.com/django/django/pull/16337

[Paul Schilling]

The previous PR's focused on avoiding/working aroung the ImportError introduced by c6864a01b25591d3a709da8071413b69c9e35341. I believe this is treating the symptoms rather than the cause.

The runserver command is split in two: the "standard" command in core/management/commands/runserver.py and the special command in contrib/staticfiles/commands/runserver.py. The latter adds --nostatic and --insecure to the arguments. However, this module imports settings from django.conf. If settings doesn't exist or has errors, contrib/staticfiles/commands/runserver.py cannot be loaded either. As a result, the --nostatic argument is not recognized because it hasn't been added (the same is true of --insecure, although this hasn't been reported).

The problem can be solved by merging the two commands. The runserver command is simplified, and the code that introduced the ImportError can be left as is.

I think ​this PR could be reviewed. Or, if the decision is to go with ​the other PR, I can close mine.

Had a look at both PRs and, from what I can tell, they both need some work
