WARNING: Don't drop the next directive! .. towncrier release notes start 3.6.2 (2019-10-09) ================== Features -------- - Made exceptions pickleable. Also changed the repr of some exceptions. `#4077 `_ - Use ``Iterable`` type hint instead of ``Sequence`` for ``Application`` *middleware* parameter. `#4125 `_ Bugfixes -------- - Reset the ``sock_read`` timeout each time data is received for a ``aiohttp.ClientResponse``. `#3808 `_ - Fix handling of expired cookies so they are not stored in CookieJar. `#4063 `_ - Fix misleading message in the string representation of ``ClientConnectorError``; ``self.ssl == None`` means default SSL context, not SSL disabled `#4097 `_ - Don't clobber HTTP status when using FileResponse. `#4106 `_ Improved Documentation ---------------------- - Added minimal required logging configuration to logging documentation. `#2469 `_ - Update docs to reflect proxy support. `#4100 `_ - Fix typo in code example in testing docs. `#4108 `_ Misc ---- - `#4102 `_ ---- 3.6.1 (2019-09-19) ================== Features -------- - Compatibility with Python 3.8. `#4056 `_ Bugfixes -------- - correct some exception string format `#4068 `_ - Emit a warning when ``ssl.OP_NO_COMPRESSION`` is unavailable because the runtime is built against an outdated OpenSSL. `#4052 `_ - Update multidict requirement to >= 4.5 `#4057 `_ Improved Documentation ---------------------- - Provide pytest-aiohttp namespace for pytest fixtures in docs. `#3723 `_ ---- 3.6.0 (2019-09-06) ================== Features -------- - Add support for Named Pipes (Site and Connector) under Windows. This feature requires Proactor event loop to work. `#3629 `_ - Removed ``Transfer-Encoding: chunked`` header from websocket responses to be compatible with more http proxy servers. `#3798 `_ - Accept non-GET request for starting websocket handshake on server side. `#3980 `_ Bugfixes -------- - Raise a ClientResponseError instead of an AssertionError for a blank HTTP Reason Phrase. `#3532 `_ - Fix an issue where cookies would sometimes not be set during a redirect. `#3576 `_ - Change normalize_path_middleware to use 308 redirect instead of 301. This behavior should prevent clients from being unable to use PUT/POST methods on endpoints that are redirected because of a trailing slash. `#3579 `_ - Drop the processed task from ``all_tasks()`` list early. It prevents logging about a task with unhandled exception when the server is used in conjunction with ``asyncio.run()``. `#3587 `_ - ``Signal`` type annotation changed from ``Signal[Callable[['TraceConfig'], Awaitable[None]]]`` to ``Signal[Callable[ClientSession, SimpleNamespace, ...]``. `#3595 `_ - Use sanitized URL as Location header in redirects `#3614 `_ - Improve typing annotations for multipart.py along with changes required by mypy in files that references multipart.py. `#3621 `_ - Close session created inside ``aiohttp.request`` when unhandled exception occurs `#3628 `_ - Cleanup per-chunk data in generic data read.

I/O based payloads from ``payload.py`` uses a ``ThreadPoolExecutor`` to work with I/O objects asynchronously. `#3313 `_ - Internal Server Errors in plain text if the browser does not support HTML. `#3483 `_ Bugfixes -------- - Preserve MultipartWriter parts headers on write. Refactor the way how ``Payload.headers`` are handled. Payload instances now always have headers and Content-Type defined. Fix Payload Content-Disposition header reset after initial creation. `#3035 `_ - Log suppressed exceptions in ``GunicornWebWorker``. `#3464 `_ - Remove wildcard imports. `#3468 `_ - Use the same task for app initialization and web server handling in gunicorn workers. It allows to use Python3.7 context vars smoothly. `#3471 `_ - Fix handling of chunked+gzipped response when first chunk does not give uncompressed data `#3477 `_ - Replace ``collections.MutableMapping`` with ``collections.abc.MutableMapping`` to avoid a deprecation warning. `#3480 `_ - ``Payload.size`` type annotation changed from ``Optional[float]`` to ``Optional[int]``. `#3484 `_ - Ignore done tasks when cancels pending activities on ``web.run_app`` finalization. `#3497 `_ Improved Documentation ---------------------- - Add documentation for ``aiohttp.web.HTTPException``. `#3490 `_ Misc ---- - `#3487 `_ ---- 3.5.1 (2018-12-24) ==================== - Fix a regression about ``ClientSession._requote_redirect_url`` modification in debug mode. 3.5.0 (2018-12-22) ==================== Features -------- - The library type annotations are checked in strict mode now. - Add support for setting cookies for individual request (`#2387 `_) - Application.add_domain implementation (`#2809 `_) - The default ``app`` in the request returned by ``test_utils.make_mocked_request`` can now have objects assigned to it and retrieved using the ``[]`` operator. (`#3174 `_) - Make ``request.url`` accessible when transport is closed. (`#3177 `_) - Add ``zlib_executor_size`` argument to ``Response`` constructor to allow compression to run in a background executor to avoid blocking the main thread and potentially triggering health check failures. (`#3205 `_) - Enable users to set ``ClientTimeout`` in ``aiohttp.request`` (`#3213 `_) - Don't raise a warning if ``NETRC`` environment variable is not set and ``~/.netrc`` file doesn't exist. (`#3267 `_) - Add default logging handler to web.run_app If the ``Application.debug``` flag is set and the default logger ``aiohttp.access`` is used, access logs will now be output using a *stderr* ``StreamHandler`` if no handlers are attached. Furthermore, if the default logger has no log level set, the log level will be set to ``DEBUG``. (`#3324 `_) - Add method argument to ``session.ws_connect()``. Sometimes server API requires a different HTTP method for WebSocket connection establishment. For example, ``Docker exec`` needs POST. (`#3378 `_) - Create a task per request handling.

(`#3258 `_) - Ensure Host header is added first to ClientRequest to better replicate browser (`#3265 `_) - Fix forward compatibility with Python 3.8: importing ABCs directly from the collections module will not be supported anymore. (`#3273 `_) - Keep the query string by ``normalize_path_middleware``. (`#3278 `_) - Fix missing parameter ``raise_for_status`` for aiohttp.request() (`#3290 `_) - Bracket IPv6 addresses in the HOST header (`#3304 `_) - Fix default message for server ping and pong frames. (`#3308 `_) - Fix tests/test_connector.py typo and tests/autobahn/server.py duplicate loop def. (`#3337 `_) - Fix false-negative indicator end_of_HTTP_chunk in StreamReader.readchunk function (`#3361 `_) - Release HTTP response before raising status exception (`#3364 `_) - Fix task cancellation when ``sendfile()`` syscall is used by static file handling. (`#3383 `_) - Fix stack trace for ``asyncio.TimeoutError`` which was not logged, when it is caught in the handler. (`#3414 `_) Improved Documentation ---------------------- - Improve documentation of ``Application.make_handler`` parameters. (`#3152 `_) - Fix BaseRequest.raw_headers doc. (`#3215 `_) - Fix typo in TypeError exception reason in ``web.Application._handle`` (`#3229 `_) - Make server access log format placeholder %b documentation reflect behavior and docstring.

Both methods were broken for more than 2 years. (`#3358 `_) - Deprecate ``app.loop``, ``request.loop``, ``client.loop`` and ``connector.loop`` properties. (`#3374 `_) - Deprecate explicit debug argument. Use asyncio debug mode instead. (`#3381 `_) - Deprecate body parameter in HTTPException (and derived classes) constructor. (`#3385 `_) - Deprecate bare connector close, use ``async with connector:`` and ``await connector.close()`` instead. (`#3417 `_) - Deprecate obsolete ``read_timeout`` and ``conn_timeout`` in ``ClientSession`` constructor. (`#3438 `_) Misc ---- - #3341, #3351
