This commit fixes ResourceWarnings in Python 3 where file objects do not appear to be closed at the end of the request, and the Django server will emit ResourceWarnings about unclosed files. The `_closable_objects` list is managed by the base FileResponse class in Django and will call `.close()` on objects at the end of the request.

This commit fixes ResourceWarnings in Python 3 where file objects do not appear to be closed at the end of the request, and the Django server will emit ResourceWarnings about unclosed files.
The
_closable_objectslist is managed by the base FileResponse class in Django and will call.close()on objects at the end of the request.Issue number
N/A
Expected behaviour
File object would be closed at the end of the request.
Actual behaviour
File object remains open.
Description of fix
The
FileResponseobject maintains a list of objects to be closed at the end of the request. Since this class uses a special reader class the file object is not appended to. This will add the file object when the instance is created. Checks to ensure file object has aclose()method, and that theFileResponseclass has the_closable_objectproperty (for compatibility).Other info
