The runserver command is missing --verbosity and --traceback

I've done some searching and don't think this is a duplicate. Basically, the documentation and a lot of other things talk about every manage command having access to both --verbosity and --traceback, however doing a runserver --traceback has no effect, neither does runserver --verbosity=2.

I think traceback in particular is necessary as anyone who is developing a RPC system using SOAP, AJAX, REST or any other four letter word can't see the literal exception that is taking place.

Marking wontfix because I'm having difficulty thinking of what either option would actually do.

I can't think of a change we could make that would increase the verbosity of the development server -- it already reports every request that hits it.

As for tracebacks -- server errors are caught and returned as 500s, but that's at a layer of abstraction deeper than the runserver command.

I'm happy to entertain the general principle of "more debug is better", but in this case, I would need to see the specific change that is being proposed.

Surely it should do what it used to do in the past? According to the discussion here, it existed in an old SVN revision:

So if it could have worked once, can't it be made to work again?

(I've got a similar problem to the OP -- this is something I would dearly like to reappear)

There is a extension called django-extensions which has a runserver_plus command, which runs a dev server with werkzeug debugger, but that is beside the point. The main point is that this runserver_plus command prints out a traceback of every exception thrown by the code.

This is very useful as the OP said in developing websites that use a lot of AJAX or RPC requests, since having to manually read HTML when scanning failed requests is bullocks.

At the very least there should be an is_ajax check that will return 500 errors with tracebacks in plain text for any ajax request, rather than full HTML that it is now.
