JSON serializes all dict keys as strings, so for compatibility the TLV
encoder should do the same. This fixes an error when tasks return dicts
with integer keys (e.g., aggregation results grouped by numeric ID).
- Add Dockerfile and docker-compose.yml for running examples in containers
- Add test_integration.py for HTTP-level integration testing
- Update test_worker_integration.py to use MockWriter for handle_request
- Use integer request IDs for binary protocol compatibility
- Add GUNICORN_BIND env var support in gunicorn_conf.py for Docker
- Update test_protocol.py example to use binary protocol
- Add test_binary_data_handling example showing raw bytes transfer
- Update dirty.md to document binary TLV protocol format
- Replace JSON references with binary protocol
- Add Binary Protocol section with header and TLV encoding details
Update client and streaming tests to work with the binary protocol:
- Update MockStreamWriter/MockStreamReader to use BinaryProtocol
- Replace string request IDs with integers
- Update test assertions to decode binary protocol messages
- Use HEADER_SIZE and decode_header/decode_message instead of old API
Update arbiter tests to work with the binary protocol:
- Update MockStreamWriter to decode binary messages
- Import binary protocol constants from module level
Update worker tests to work with the binary protocol:
- Use integer request IDs instead of strings
- Update MockStreamWriter to decode binary messages
- Import binary protocol constants from module level
Replace JSON-based protocol with binary format using 16-byte header:
- Magic bytes (GD), version, message type, payload length, request ID
- TLV-encoded payloads for efficient binary data transfer
- No base64 encoding needed for binary data
- Backwards compatible API (DirtyProtocol alias, dict-based interface)
Header format inspired by OpenBSD msgctl/msgsnd.
- Add sponsor banner at top of README
- Add Revolut and Open Collective to FUNDING.yml
- Add dedicated sponsor page in docs
- Add sponsor heart link in footer
- Change title from "The Python WSGI Server" to "Serve Python Apps on the Web"
- Remove "Version {{ version }}" text from hero section
- Remove unused .hero__version CSS
In Python 3.7+, PEP 479 converts StopIteration raised inside coroutines
to RuntimeError. Changed _read_into() to raise NoMoreData instead, which
is already properly handled by the protocol layer.
- 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
Closes#3484
When a client disconnects during an ASGI request, the worker now:
1. Sends http.disconnect message to the app's receive queue
2. Allows a configurable grace period for cleanup (default: 3 seconds)
3. Only cancels the task after the grace period expires
This follows the ASGI HTTP Connection Scope spec which defines
http.disconnect as the message apps should receive when clients
disconnect: https://asgi.readthedocs.io/en/latest/specs/www.html#disconnect-receive-event
The grace period prevents CancelledError from propagating to async
database operations, allowing SQLAlchemy and other async DB libraries
to properly reset their connection pools.
New config option: --asgi-disconnect-grace-period (default: 3 seconds)
Closes#3482
The dirty module (which uses asyncio and concurrent.futures) was being
imported at gunicorn startup via gunicorn.arbiter. This caused
concurrent.futures to be imported before user code could call
gevent.monkey.patch_all(), breaking gevent's monkey-patching.
Changes:
- gunicorn/arbiter.py: Import DirtyArbiter and set_dirty_socket_path
lazily inside spawn_dirty_arbiter() instead of at module level
- gunicorn/dirty/worker.py: Import ThreadPoolExecutor lazily inside
run() method instead of at module level
- Add tests/workers/test_gevent_import_order.py with 5 tests verifying:
- concurrent.futures is NOT imported when gunicorn.arbiter loads
- gevent patching works correctly with gunicorn
- Reproduces the exact scenario from the bug report gist
This ensures gevent's monkey.patch_all() can run before concurrent.futures
is imported, allowing proper patching of threading primitives.
- 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 chunked transfer encoding support to the ASGI worker for HTTP/1.1
streaming responses that don't have a Content-Length header. This fixes
SSE (Server-Sent Events) connections not closing properly.
Without chunked encoding or Content-Length, HTTP/1.1 clients wait for
the connection to close to determine end-of-response, causing streaming
endpoints to hang.
Also updates the celery_alternative example to use FastAPI with the
native ASGI worker and uvloop, demonstrating async task execution with
proper SSE streaming.
