#16519 closed Cleanup/optimization (fixed)

mimetype used with HttpResponse should be deprecated

Description

Passing the mimetype argument when instantiating HttpResponse should raise a DeprecationWarning.

The mimetype argument has been deprecated via comment in the code for 4 years: https://code.djangoproject.com/changeset/5844/django/trunk/django/http/__init__.py

It's about time we actually raised a DeprecationWarning and remove the thing ASAP. If we swap the position of the mimetype and content_type arguments, code the relies on argument position will continue to function without raising the warning. The only code that will need to be changed is code that explicitly uses the mimetype kwarg (including a bunch of django tests).

This situation is long-lived enough to bypass the PendingDeprecationWarning.

I don't think it hurts to keep the backwards compatibility code for another release, so this should definitely be a PendingDeprecationWarning

Alright. I suppose it doesn't hurt anything to have it pending for a bit.

I am new to contributing, and I shoud ask if I should fix contrib packages too. I mean replacing mimetype with content_type where needed?

comment:6 by Paul McMillan, 13 years ago

Yes, you'll need to fix it everywhere it occurs in the Django codebase, including the tests. You'll also probably need to write some new tests. If you swap the order of mimetype and content_type in the definition, the functions that are using mimetype as a positional argument will transition more easily.

Ok. A patch would be available in couple of days I guess. I am excited as this will be my first actual contrib to django :)

If you are talking about django.contrib.* then the answer is yes. Thanks for looking at this.

I made a patch file where I made warning and changed mimetype kwarg, to content_type kwarg. However, I didn't write tests for it, as I am not sure what I am test for here, something like this maybe?

import warnings
from django.http import HttpResponse

with warnings.catch_warnings(record=True) as w:
    warnings.simplefilter("always")
    HttpResponse(mimetype="text/html")

    assert len(w) == 1
    assert issubclass(w[-1].category, DeprecationWarning)
    assert "deprecated" in str(w[-1].message)

Sorry about marking as RFC. I didn't know I didn't supposed to do that.

Fixed #16519 -- Deprecated mimetype kwarg of HttpResponse init

This keyword was already deprecated in the code (supported for
backwards compatibility only), but never formally deprecated.
Thanks Paul McMillan for the report and yasar11732 for the initial
patch.
