Add support for the uWSGI binary protocol, enabling gunicorn to work
with nginx's uwsgi_pass directive.
New module gunicorn/uwsgi/ with:
- UWSGIRequest: Parses 4-byte binary header and key-value vars block
- UWSGIParser: Protocol parser following existing Parser pattern
- Error classes: InvalidUWSGIHeader, UnsupportedModifier, ForbiddenUWSGIRequest
New configuration options:
- --protocol: Select 'http' (default) or 'uwsgi' protocol
- --uwsgi-allow-from: IP allowlist for uWSGI requests (default: localhost)
Worker integration via get_parser() factory in gunicorn/http/__init__.py,
updates to sync, gthread, and base_async workers.
Example nginx config:
upstream gunicorn {
server 127.0.0.1:8000;
}
location / {
uwsgi_pass gunicorn;
include uwsgi_params;
}
