#22066: KeyError in settings.py leads to baffling 'Unknown command' error
--------------------------------------------+--------------------
Reporter: michael.karl.coleman@… | Owner: nobody
Type: Bug | Status: new
Component: Core (Management commands) | Version: 1.6
Severity: Normal | Keywords:
Triage Stage: Unreviewed | Has patch: 0

--------------------------------------------+--------------------
In two places in core/management/__init__.py, there is code like this
{{{
try:
app_name = get_commands()[name]
except KeyError:
raise CommandError("Unknown command: %r" % name)
}}}
Unfortunately, KeyErrors from settings.py seem to get caught here, leading
to a baffling error message. The fix would be to just do something like
{{{
commands = get_commands()
if name not in commands:
raise CommandError("Unknown command: %r" % name)
app_name = name
}}}
and let any KeyError from settings.py escape as a backtrace, so that the
user can see and fix it directly.
Unfortunately, I don't have time to recreate this and verify that it still
exists in HEAD, but just looking at the code, I think it probably does.
This is related to #19257, but I don't believe it's the same bug.
