- Bump version to 25.0.2
- Update copyright year to 2026 in LICENSE and NOTICE
- Add license headers to all Python source files
- Add changelog entry for 25.0.2
- Fix nginx config to use keepalive with upstream (was sending
Connection: close which caused premature connection closure)
- Add _safe_write() to handle socket errors (EPIPE, ECONNRESET,
ENOTCONN) gracefully when client disconnects
- Fix ASGI scope server/client to always be 2-tuples for IPv6
compatibility (IPv6 sockets return 4-tuples)
- Add write_eof() before close() to ensure buffered data is flushed
- Bind to [::] for dual-stack IPv4/IPv6 support in test containers
- Fix path expectation in test_scope_path_preserved (router strips /http prefix)
- Fix lifespan state check to use scope_state instead of module_state
- Add tolerance for partial failures in proxy concurrent test
- Add retry logic with proper assertions in HTTPS proxy FastAPI test
- Add get_app_workers_attribute() to read workers class attribute
- Update _parse_app_specs() to check class attribute when no config override
- Add Docker-based e2e tests for per-app worker allocation
- Add test apps: HeavyModelApp (workers=2), LightweightApp
- Add unit tests for get_app_workers_attribute function
- Add integration tests for class attribute detection
Implement HTTP 103 Early Hints as modern replacement for HTTP/2 Server Push.
This allows servers to send resource hints before the final response,
enabling browsers to preload assets in parallel.
WSGI support:
- Add wsgi.early_hints callback to environ dict
- Apps can call environ['wsgi.early_hints'](headers) to send 103 responses
- Silently ignored for HTTP/1.0 clients (don't support 1xx responses)
ASGI support:
- Handle http.response.informational message type
- Apps can await send({"type": "http.response.informational", "status": 103, ...})
HTTP/2 support:
- Add send_informational() method to HTTP2ServerConnection
- Add async send_informational() method to AsyncHTTP2Connection
- Wire up early hints in gthread worker for HTTP/2 requests
Includes unit tests and Docker integration tests for all protocols.
Tests the ASGI worker with direct HTTP requests without uWSGI protocol.
Includes tests for GET, POST, query strings, path handling, keepalive,
large bodies, and custom headers.
Add uWSGI protocol support to ASGI worker
- Implements AsyncUWSGIRequest class extending sync UWSGIRequest to reuse parsing logic with async I/O
- ASGI protocol handler selects between HTTP and uWSGI based on --protocol config option
- Allows gunicorn's ASGI worker to receive requests from nginx using uwsgi_pass directive
- Includes unit tests and Docker integration tests
Add comprehensive Docker integration tests verifying dirty arbiter
lifecycle under realistic conditions:
- Parent death detection via ppid monitoring
- Orphan cleanup on restart
- Dirty arbiter respawning after crash
- Graceful shutdown with SIGTERM
Also fix race condition in manage_workers() by checking self.alive
before spawning new workers during shutdown.
