daphne-协议服务器-Python

4.1.3 (to be released) ------------------ * Removed unused pytest-runner * Fixed sdist file to ensure it includes all tests 4.1.2 (2024-04-11) ------------------ * Fixed a setuptools configuration error in 4.1.1. 4.1.1 (2024-04-10) ------------------ * Fixed a twisted.plugin packaging error in 4.1.0. Thanks to sdc50. 4.1.0 (2024-02-10) ------------------ * Added support for Python 3.12. * Dropped support for EOL Python 3.7. * Handled root path for websocket scopes. * Validate HTTP header names as per RFC 9110. 4.0.0 (2022-10-07) ------------------ Major versioning targeting use with Channels 4.0 and beyond. Except where noted should remain usable with Channels v3 projects, but updating Channels to the latest version is recommended. * Added a ``runserver`` command to run an ASGI Django development server. Added ``"daphne"`` to the ``INSTALLED_APPS`` setting, before ``"django.contrib.staticfiles"`` to enable: INSTALLED_APPS = [ "daphne", ... ] This replaces the Channels implementation of ``runserver``, which is removed in Channels 4.0. * Made the ``DaphneProcess`` tests helper class compatible with the ``spawn`` process start method, which is used on macOS and Windows. Note that requires Channels v4 if using with ``ChannelsLiveServerTestCase``. * Dropped support for Python 3.6. * Updated dependencies to the latest versions. Previously a range of Twisted versions have been supported. Recent Twisted releases (22.2, 22.4) have issued security fixes, so those are now the minimum supported version. Given the stability of Twisted, supporting a range of versions does not represent a good use of maintainer time. Going forward the latest Twisted version will be required. * Set ``daphne`` as default ``Server`` header. This can be configured with the ``--server-name`` CLI argument. Added the new ``--no-server-name`` CLI argument to disable the ``Server`` header, which is equivalent to ``--server-name=` (an empty name). * Added ``--log-fmt`` CLI argument. * Added support for ``ASGI_THREADS`` environment variable, setting the maximum number of workers used by a ``SyncToAsync`` thread-pool executor. Set e.g. ``ASGI_THREADS=4 daphne ...`` when running to limit the number of workers. * Removed deprecated ``--ws_protocols`` CLI option. 3.0.2 (2021-04-07) ------------------ * Fixed a bug where ``send`` passed to applications wasn't a true async function but a lambda wrapper, preventing it from being used with ``asgiref.sync.async_to_sync()``. 3.0.1 (2020-11-12) ------------------ * Fixed a bug where ``asyncio.CancelledError`` was not correctly handled on Python 3.8+, resulting in incorrect protocol application cleanup. 3.0.0 (2020-10-28) ------------------ * Updates internals to use ASGI v3 throughout. ``asgiref.compatibility`` is used for older applications. * Consequently, the `--asgi-protocol` command-line option is removed. * HTTP request bodies are now read, and passed to the application, in chunks. * Added support for Python 3.9. * Dropped support for Python 3.5. 2.5.0 (2020-04-15) ------------------ * Fixes compatability for twisted when running Python 3.8+ on Windows, by setting ``asyncio.WindowsSelectorEventLoopPolicy`` as the event loop policy in this case. * The internal ``daphne.testing.TestApplication`` now requires an addition ``lock`` argument to ``__init__()``. This is expected to be an instance of ``multiprocessing.Lock``. 2.4.1 (2019-12-18) ------------------ * Avoids Twisted using the default event loop, for compatibility with Django 3.0's ``async_unsafe()`` decorator in threaded contexts, such as using the auto-reloader. 2.4.0 (2019-11-20) ------------------ * Adds CI testing against and support for Python 3.8. * Adds support for ``raw_path`` in ASGI scope. * Ensures an error response is sent to the client if the application sends malformed headers. * Resolves an asyncio + multiprocessing problem when testing that would cause the test suite to fail/hang on macOS. * Requires installing Twisted's TLS extras, via ``install_requires``. * Adds missing LICENSE to distribution. 2.3.0 (2019-04-09) ------------------ * Added support for ASGI v3. 2.2.5 (2019-01-31) ------------------ * WebSocket handshakes are now affected by the websocket connect timeout, so you can limit them from the command line. * Server name can now be set using --server-name 2.2.4 (2018-12-15) ------------------ * No longer listens on port 8000 when a file descriptor is provided with --fd * Fixed a memory leak with WebSockets 2.2.3 (2018-11-06) ------------------ * Enforce that response headers are only bytestrings, rather than allowing unicode strings and coercing them into bytes. * New command-line options to set proxy header names: --proxy-headers-host and --proxy-headers-port. 2.2.2 (2018-08-16) ------------------ * X-Forwarded-Proto support is now present and enabled if you turn on the --proxy-headers flag * ASGI applications are no longer instantiated in a thread (the ASGI spec was finalised to say all constructors must be non-blocking on the main thread) 2.2.1 (2018-07-22) ------------------ * Python 3.7 compatability is flagged and ensured by using Twisted 18.7 and above as a dependency. * The send() awaitable in applications no longer blocks if the connection is closed. * Fixed a race condition where applications would be cleaned up before they had even started. 2.2.0 (2018-06-13) ------------------ * HTTP timeouts have been removed by default, as they were only needed with ASGI/Channels 1. You can re-enable them with the --http-timeout argument to Daphne. * Occasional errors on application timeout for non-fully-opened sockets and for trying to read closed requests under high load are fixed. * X-Forwarded-For headers are now correctly decoded in all environments and no longer have unicode matching issues. 2.1.2 (2018-05-24) ------------------ * Fixed spurious errors caused by websockets disconnecting before their application was instantiated. * Stronger checking for type-safety of headers as bytestrings 2.1.1 (2018-04-18) ------------------ * ASGI application constructors are now run in a threadpool as they might contain blocking synchronous code. 2.1.0 (2018-03-05) ------------------ * Removed subprotocol support from server, as it never really worked. Subprotocols can instead be negotiated by ASGI applications now. * Non-ASCII query strings now raise a 400 Bad Request error rather than silently breaking the logger 2.0.4 (2018-02-21) ------------------ * Ping timeouts no longer reset on outgoing data, only incoming data * No more errors when connections close prematurely 2.0.3 (2018-02-07) ------------------ * Unix socket listening no longer errors during startup (introduced in 2.0.2) * ASGI Applications are now not immediately killed on disconnection but instead given --application-close-timeout seconds to exit (defaults to 10) 2.0.2 (2018-02-04) ------------------ * WebSockets are no longer closed after the duration of http_timeout 2.0.1 (2018-02-03) ------------------ * Updated logging to correctly route exceptions through the main Daphne logger 2.0.0 (2018-02-01) ------------------ * Major rewrite to the new async-based ASGI specification and to support Channels 2. Not backwards compatible. 1.3.0 (2017-06-16) ------------------ * Ability to set the websocket connection timeout * Server no longer reveals the exact Autobahn version number for security * A few unicode fixes for Python 2/3 compatability * Stopped logging messages to already-closed connections as ERROR 1.2.0 (2017-04-01) ------------------ * The new process-specific channel support is now implemented, resulting in significantly less traffic to your channel backend. * Native twisted blocking support for channel layers that support it is now used. While it is a lot more efficient,
