Add callback parser support to ASGIProtocol: - Add _handle_connection_callback() for callback-based parsing - Add parser callbacks: _on_headers_complete, _on_body, _on_message_complete - Update data_received() to feed callback parser - Add _setup_callback_parser() with H1CProtocol/PythonProtocol selection Add http_parser config options: - callback: Use callback parser (H1CProtocol if available, else PythonProtocol) - fast-callback: Require H1CProtocol callback parser Callback parsing moves HTTP parsing to data_received(), reducing async overhead in the request handling loop.
Gunicorn
Gunicorn is maintained by volunteers. If it powers your production, please consider supporting us:
Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. It's a pre-fork worker model ported from Ruby's Unicorn project. The Gunicorn server is broadly compatible with various web frameworks, simply implemented, light on server resource usage, and fairly speedy.
New in v25: Per-app worker allocation for dirty arbiters, HTTP/2 support (beta)!
Quick Start
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
- Graceful worker process management
