* Add InvalidChunkExtension to treq_asgi.py and fast parser support - Add InvalidChunkExtension import and exception mapping for proper test coverage of bare CR rejection in chunk extensions per RFC 9112 7.1.1 - Add fast parser (H1CProtocol) support to treq_asgi.py and the ASGI invalid request tests - Fast parser now receives limit configuration (limit_request_line, limit_request_fields, limit_request_field_size) - Handle gunicorn_h1c's multiple ParseError classes from different modules - Skip tests where fast parser has different validation than Python parser * Handle gunicorn_h1c limit exceptions in ASGI protocol Add handling for gunicorn_h1c.LimitRequestLine and gunicorn_h1c.LimitRequestHeaders exceptions, matching the behavior of the Python parser exceptions with appropriate HTTP status codes: - LimitRequestLine: 414 URI Too Long - LimitRequestHeaders: 431 Request Header Fields Too Large * Refactor data_received to fix too-many-return-statements lint
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
- Compatible with Python 3.9+
