Benoit Chesneau 82d33d4c71 fix: reject asterisk-form request-target outside OPTIONS (RFC 9112 section 3.2.4)
The Python WSGI and ASGI parsers both accepted `GET *` and similar; RFC
9112 restricts asterisk-form to OPTIONS. Both now raise InvalidRequestLine.

The fast (C) parser in gunicorn_h1c does not yet enforce this, so the
fixture is marked python_only via a new sidecar flag honored by the WSGI
and ASGI invalid-request harnesses.

pip install gunicorn
gunicorn myapp:app --workers 4

For ASGI applications (FastAPI, Starlette):

gunicorn myapp:app --worker-class asgi

Features

  • WSGI support for Django, Flask, Pyramid, and any WSGI framework
  • ASGI support for FastAPI, Starlette, Quart
  • HTTP/2 support (beta) with multiplexed streams
  • Dirty Arbiters (beta) for heavy workloads (ML models, long-running tasks)
  • uWSGI binary protocol for nginx integration
  • Multiple worker types: sync, gthread, gevent, eventlet, asgi
