== Problem
Django's `parse_file_upload()` hardcodes `MultiPartParser`, making it hard
to swap in faster implementations.
== Proposed Solution
As discussed with the steering council and Carlton Gibson on the forum:
1. Add `multipart_parser_class` class attribute to `HttpRequest`
(defaulting to `MultiPartParser`)
2. Modify `parse_file_upload()` to use `self.multipart_parser_class`
instead of direct import
3. Ensure uniform parser interface: `__init__(META, input_data,
upload_handlers, encoding)`
with `parse()` returning `(POST, FILES)`
== Usage
Users can subclass `HttpRequest` and override `multipart_parser_class` to
use
faster parsers.
== Benefits
- Immediate performance improvements for those who need them
- Stepping stone toward DEP 17 https://github.com/django/deps/pull/88
(pluggable content type parsers)
- Minimal change
- Follows proven pattern from Django REST Framework's `parser_classes`
