* Mon Jul 29 2019 Todd R - Rename to python-tornado6 to handle version incompatibilities- Update to 6.0.3 + Bug fixes
* `.gen.with_timeout` always treats ``asyncio.CancelledError`` as a ``quiet_exception`` (this improves compatibility with Python 3.8, which changed ``CancelledError`` to a ``BaseException``).
* ``IOStream`` now checks for closed streams earlier, avoiding spurious logged errors in some situations (mainly with websockets).- Update to 6.0.2 + Bug fixes
* `.WebSocketHandler.set_nodelay` works again.
* Accessing ``HTTPResponse.body`` now returns an empty byte string instead of raising ``ValueError`` for error responses that don\'t have a body (it returned None in this case in Tornado 5).- Update to 6.0.1 + Bug fixes
* Fixed issues with type annotations that caused errors while importing Tornado on Python 3.5.2.- Update to 6.0.0 + Backwards-incompatible changes
* Python 2.7 and 3.4 are no longer supported; the minimum supported Python version is 3.5.2.
* APIs deprecated in Tornado 5.1 have been removed. This includes the ``tornado.stack_context`` module and most ``callback`` arguments throughout the package. All removed APIs emitted `DeprecationWarning` when used in Tornado 5.1, so running your application with the ``-Wd`` Python command-line flag or the environment variable ``PYTHONWARNINGS=d`` should tell you whether your application is ready to move to Tornado 6.0.
* ``.WebSocketHandler.get`` is now a coroutine and must be called accordingly in any subclasses that override this method (but note that overriding ``get`` is not recommended; either ``prepare`` or ``open`` should be used instead). + General changes
* Tornado now includes type annotations compatible with ``mypy``. These annotations will be used when type-checking your application with ``mypy``, and may be usable in editors and other tools.
* Tornado now uses native coroutines internally, improving performance. + tornado.auth
* All ``callback`` arguments in this package have been removed. Use the coroutine interfaces instead.
* The ``OAuthMixin._oauth_get_user`` method has been removed. Override `~.OAuthMixin._oauth_get_user_future` instead. + tornado.concurrent
* The ``callback`` argument to `.run_on_executor` has been removed.
* ``return_future`` has been removed. + tornado.gen
* Some older portions of this module have been removed. This includes ``engine``, ``YieldPoint``, ``Callback``, ``Wait``, ``WaitAll``, ``MultiYieldPoint``, and ``Task``.
* Functions decorated with ``AATTgen.coroutine`` no longer accept ``callback`` arguments. + tornado.httpclient
* The behavior of ``raise_error=False`` has changed. Now only suppresses the errors raised due to completed responses with non-200 status codes (previously it suppressed all errors).
* The ``callback`` argument to `.AsyncHTTPClient.fetch` has been removed. + tornado.httputil
* ``HTTPServerRequest.write`` has been removed. Use the methods of ``request.connection`` instead.
* Unrecognized ``Content-Encoding`` values now log warnings only for content types that we would otherwise attempt to parse. + tornado.ioloop
* ``IOLoop.set_blocking_signal_threshold``, ``IOLoop.set_blocking_log_threshold``, ``IOLoop.log_stack``, and ``IOLoop.handle_callback_exception`` have been removed.
* Improved performance of `.IOLoop.add_callback`. + tornado.iostream
* All ``callback`` arguments in this module have been removed except for `.BaseIOStream.set_close_callback`.
* ``streaming_callback`` arguments to `.BaseIOStream.read_bytes` and `.BaseIOStream.read_until_close` have been removed.
* Eliminated unnecessary logging of \"Errno 0\". + tornado.log
* Log files opened by this module are now explicitly set to UTF-8 encoding. + tornado.netutil
* The results of ``getaddrinfo`` are now sorted by address family to avoid partial failures and deadlocks. + tornado.platform.twisted
* ``TornadoReactor`` and ``TwistedIOLoop`` have been removed. + tornado.simple_httpclient
* The default HTTP client now supports the ``network_interface`` request argument to specify the source IP for the connection.
* If a server returns a 3xx response code without a ``Location`` header, the response is raised or returned directly instead of trying and failing to follow the redirect.
* When following redirects, methods other than ``POST`` will no longer be transformed into ``GET`` requests. 301 (permanent) redirects are now treated the same way as 302 (temporary) and 303 (see other) redirects in this respect.
* Following redirects now works with ``body_producer``. + tornado.stack_context
* The ``tornado.stack_context`` module has been removed. + tornado.tcpserver
* `.TCPServer.start` now supports a ``max_restarts`` argument (same as `.fork_processes`). + tornado.testing
* `.AsyncHTTPTestCase` now drops all references to the `.Application` during ``tearDown``, allowing its memory to be reclaimed sooner.
* `.AsyncTestCase` now cancels all pending coroutines in ``tearDown``, in an effort to reduce warnings from the python runtime about coroutines that were not awaited. Note that this may cause ``asyncio.CancelledError`` to be logged in other places. Coroutines that expect to be running at test shutdown may need to catch this exception. + tornado.web
* The ``asynchronous`` decorator has been removed.
* The ``callback`` argument to `.RequestHandler.flush` has been removed.
* `.StaticFileHandler` now supports large negative values for the ``Range`` header and returns an appropriate error for ``end > start``.
* It is now possible to set ``expires_days`` in ``xsrf_cookie_kwargs``. + tornado.websocket
* Pings and other messages sent while the connection is closing are now silently dropped instead of logging exceptions.
* Errors raised by ``open()`` are now caught correctly when this method is a coroutine. + tornado.wsgi
* ``WSGIApplication`` and ``WSGIAdapter`` have been removed.- Rebase patches:
* tornado-testsuite_timeout.patch
* skip-failing-tests.patch- Remove upstream-included openssl-cert-size.patch
* Mon Jul 29 2019 Todd R - Rename to python-tornado5 to handle version incompatibilities- Update to 5.1.1 + Bug fixes
* Fixed an case in which the `.Future` returned by `.RequestHandler.finish` could fail to resolve.
* The `.TwitterMixin.authenticate_redirect` method works again.
* Improved error handling in the `tornado.auth` module, fixing hanging requests when a network or other error occurs.- Update to 5.1.0 + Deprecation notice
* Tornado 6.0 will drop support for Python 2.7 and 3.4. The minimum supported Python version will be 3.5.2.
* The ``tornado.stack_context`` module is deprecated and will be removed in Tornado 6.0. The reason for this is that it is not feasible to provide this module\'s semantics in the presence of ``async def`` native coroutines. ``ExceptionStackContext`` is mainly obsolete thanks to coroutines. ``StackContext`` lacks a direct replacement although the new ``contextvars`` package (in the Python standard library beginning in Python 3.7) may be an alternative.
* Callback-oriented code often relies on ``ExceptionStackContext`` to handle errors and prevent leaked connections. In order to avoid the risk of silently introducing subtle leaks (and to consolidate all of Tornado\'s interfaces behind the coroutine pattern), ``callback`` arguments throughout the package are deprecated and will be removed in version 6.0. All functions that had a ``callback`` argument removed now return a `.Future` which should be used instead.
* Where possible, deprecation warnings are emitted when any of these deprecated interfaces is used. However, Python does not display deprecation warnings by default. To prepare your application for Tornado 6.0, run Python with the ``-Wd`` argument or set the environment variable ``PYTHONWARNINGS`` to ``d``. If your application runs on Python 3 without deprecation warnings, it should be able to move to Tornado 6.0 without disruption. + tornado.auth
* `.OAuthMixin._oauth_get_user_future` may now be a native coroutine.
* All ``callback`` arguments in this package are deprecated and will be removed in 6.0. Use the coroutine interfaces instead.
* The ``OAuthMixin._oauth_get_user`` method is deprecated and will be removed in 6.0. Override `~.OAuthMixin._oauth_get_user_future` instead. + tornado.autoreload
* The command-line autoreload wrapper is now preserved if an internal autoreload fires.
* The command-line wrapper no longer starts duplicated processes on windows when combined with internal autoreload. + tornado.concurrent
* `.run_on_executor` now returns `.Future` objects that are compatible with ``await``.
* The ``callback`` argument to `.run_on_executor` is deprecated and will be removed in 6.0.
* ``return_future`` is deprecated and will be removed in 6.0. + tornado.gen
* Some older portions of this module are deprecated and will be removed in 6.0. This includes ``engine``, ``YieldPoint``, ``Callback``, ``Wait``, ``WaitAll``, ``MultiYieldPoint``, and ``Task``.
* Functions decorated with ``AATTgen.coroutine`` will no longer accept ``callback`` arguments in 6.0. + tornado.httpclient
* The behavior of ``raise_error=False`` is changing in 6.0. Currently it suppresses all errors; in 6.0 it will only suppress the errors raised due to completed responses with non-200 status codes.
* The ``callback`` argument to `.AsyncHTTPClient.fetch` is deprecated and will be removed in 6.0.
* `tornado.httpclient.HTTPError` has been renamed to `.HTTPClientError` to avoid ambiguity in code that also has to deal with `tornado.web.HTTPError`. The old name remains as an alias.
* ``tornado.curl_httpclient`` now supports non-ASCII characters in username and password arguments.
* ``.HTTPResponse.request_time`` now behaves consistently across ``simple_httpclient`` and ``curl_httpclient``, excluding time spent in the ``max_clients`` queue in both cases (previously this time was included in ``simple_httpclient`` but excluded in ``curl_httpclient``). In both cases the time is now computed using a monotonic clock where available.
* `.HTTPResponse` now has a ``start_time`` attribute recording a wall-clock (`time.time`) timestamp at which the request started (after leaving the ``max_clients`` queue if applicable). + tornado.httputil
* `.parse_multipart_form_data` now recognizes non-ASCII filenames in RFC 2231/5987 (``filename
*=``) format.
* ``HTTPServerRequest.write`` is deprecated and will be removed in 6.0. Use the methods of ``request.connection`` instead.
* Malformed HTTP headers are now logged less noisily. + tornado.ioloop
* `.PeriodicCallback` now supports a ``jitter`` argument to randomly vary the timeout.
* ``IOLoop.set_blocking_signal_threshold``, ``IOLoop.set_blocking_log_threshold``, ``IOLoop.log_stack``, and ``IOLoop.handle_callback_exception`` are deprecated and will be removed in 6.0.
* Fixed a `KeyError` in `.IOLoop.close` when `.IOLoop` objects are being opened and closed in multiple threads. + tornado.iostream
* All ``callback`` arguments in this module are deprecated except for `.BaseIOStream.set_close_callback`. They will be removed in 6.0.
* ``streaming_callback`` arguments to `.BaseIOStream.read_bytes` and `.BaseIOStream.read_until_close` are deprecated and will be removed in 6.0. + tornado.netutil
* Improved compatibility with GNU Hurd. + tornado.options
* `tornado.options.parse_config_file` now allows setting options to strings (which will be parsed the same way as `tornado.options.parse_command_line`) in addition to the specified type for the option. + tornado.platform.twisted
* ``TornadoReactor`` and ``TwistedIOLoop`` are deprecated and will be removed in 6.0. Instead, Tornado will always use the asyncio event loop and twisted can be configured to do so as well. ``tornado.stack_context``
* The ``tornado.stack_context`` module is deprecated and will be removed in 6.0. + tornado.testing
* `.AsyncHTTPTestCase.fetch` now takes a ``raise_error`` argument. This argument has the same semantics as `.AsyncHTTPClient.fetch`, but defaults to false because tests often need to deal with non-200 responses (and for backwards-compatibility).
* The `.AsyncTestCase.stop` and `.AsyncTestCase.wait` methods are deprecated. + tornado.web
* New method `.RequestHandler.detach` can be used from methods that are not decorated with ``AATTasynchronous`` (the decorator was required to use ``self.request.connection.detach()``.
* `.RequestHandler.finish` and `.RequestHandler.render` now return ``Futures`` that can be used to wait for the last part of the response to be sent to the client.
* `.FallbackHandler` now calls ``on_finish`` for the benefit of subclasses that may have overridden it.
* The ``asynchronous`` decorator is deprecated and will be removed in 6.0.
* The ``callback`` argument to `.RequestHandler.flush` is deprecated and will be removed in 6.0. + tornado.websocket
* When compression is enabled, memory limits now apply to the post-decompression size of the data, protecting against DoS attacks.
* `.websocket_connect` now supports subprotocols.
* `.WebSocketHandler` and `.WebSocketClientConnection` now have ``selected_subprotocol`` attributes to see the subprotocol in use.
* The `.WebSocketHandler.select_subprotocol` method is now called with an empty list instead of a list containing an empty string if no subprotocols were requested by the client.
* `.WebSocketHandler.open` may now be a coroutine.
* The ``data`` argument to `.WebSocketHandler.ping` is now optional.
* Client-side websocket connections no longer buffer more than one message in memory at a time.
* Exception logging now uses `.RequestHandler.log_exception`. + tornado.wsgi
* ``WSGIApplication`` and ``WSGIAdapter`` are deprecated and will be removed in Tornado 6.0.- Update to 5.0.2 + Bug fixes
* Fixed a memory leak when `.IOLoop` objects are created and destroyed.
* If `.AsyncTestCase.get_new_ioloop` returns a reference to a preexisting event loop (typically when it has been overridden to return `.IOLoop.current()`), the test\'s ``tearDown`` method will not close this loop.
* Fixed a confusing error message when the synchronous `.HTTPClient` fails to initialize because an event loop is already running.
* `.PeriodicCallback` no longer executes twice in a row due to backwards clock adjustments.- Update to 5.0.1 + Bug fix
* This release restores support for versions of Python 3.4 prior to 3.4.4. This is important for compatibility with Debian Jessie which has 3.4.2 as its version of Python 3. + Highlights
* The focus of this release is improving integration with `asyncio`. On Python 3, the `.IOLoop` is always a wrapper around the `asyncio` event loop, and `asyncio.Future` and `asyncio.Task` are used instead of their Tornado counterparts. This means that libraries based on `asyncio` can be mixed relatively seamlessly with those using Tornado. While care has been taken to minimize the disruption from this change, code changes may be required for compatibility with Tornado 5.0, as detailed in the following section.
* Tornado 5.0 supports Python 2.7.9+ and 3.4+. Python 2.7 and 3.4 are deprecated and support for them will be removed in Tornado 6.0, which will require Python 3.5+. + Backwards-compatibility notes
* Python 3.3 is no longer supported.
* Versions of Python 2.7 that predate the `ssl` module update are no longer supported. (The `ssl` module was updated in version 2.7.9, although in some distributions the updates are present in builds with a lower version number. Tornado requires `ssl.SSLContext`, `ssl.create_default_context`, and `ssl.match_hostname`)
* Versions of Python 3.5 prior to 3.5.2 are no longer supported due to a change in the async iterator protocol in that version.
* The ``trollius`` project (`asyncio` backported to Python 2) is no longer supported.
* `tornado.concurrent.Future` is now an alias for `asyncio.Future` when running on Python 3. This results in a number of minor behavioral changes: > `.Future` objects can only be created while there is a current `.IOLoop` > The timing of callbacks scheduled with ``Future.add_done_callback`` has changed. `tornado.concurrent.future_add_done_callback` can be used to make the behavior more like older versions of Tornado (but not identical). Some of these changes are also present in the Python 2 version of `tornado.concurrent.Future` to minimize the difference between Python 2 and 3. > Cancellation is now partially supported, via `asyncio.Future.cancel`. A canceled `.Future` can no longer have its result set. Applications that handle `~asyncio.Future` objects directly may want to use `tornado.concurrent.future_set_result_unless_cancelled`. In native coroutines, cancellation will cause an exception to be raised in the coroutine. > The ``exc_info`` and ``set_exc_info`` methods are no longer present. Use `tornado.concurrent.future_set_exc_info` to replace the latter, and raise the exception with `~asyncio.Future.result` to replace the former.
* ``io_loop`` arguments to many Tornado functions have been removed. Use `.IOLoop.current()` instead of passing `.IOLoop` objects explicitly.
* On Python 3, `.IOLoop` is always a wrapper around the `asyncio` event loop. ``IOLoop.configure`` is effectively removed on Python 3 (for compatibility, it may be called to redundantly specify the `asyncio`-backed `.IOLoop`)
* `.IOLoop.instance` is now a deprecated alias for `.IOLoop.current`. Applications that need the cross-thread communication behavior facilitated by `.IOLoop.instance` should use their own global variable instead. + Other notes
* The ``futures`` (`concurrent.futures` backport) package is now required on Python 2.7.
* The ``certifi`` and ``backports.ssl-match-hostname`` packages are no longer required on Python 2.7.
* Python 3.6 or higher is recommended, because it features more efficient garbage collection of `asyncio.Future` objects. + tornado.auth
* `.GoogleOAuth2Mixin` now uses a newer set of URLs. + tornado.autoreload
* On Python 3, uses ``__main__.__spec`` to more reliably reconstruct the original command line and avoid modifying ``PYTHONPATH``.
* The ``io_loop`` argument to `tornado.autoreload.start` has been removed. + tornado.concurrent
* `tornado.concurrent.Future` is now an alias for `asyncio.Future` when running on Python 3. See \"Backwards-compatibility notes\" for more.
* Setting the result of a ``Future`` no longer blocks while callbacks are being run. Instead, the callbacks are scheduled on the next `.IOLoop` iteration.
* The deprecated alias ``tornado.concurrent.TracebackFuture`` has been removed.
* `tornado.concurrent.chain_future` now works with all three kinds of ``Futures`` (Tornado, `asyncio`, and `concurrent.futures`)
* The ``io_loop`` argument to `tornado.concurrent.run_on_executor` has been removed.
* New functions `.future_set_result_unless_cancelled`, `.future_set_exc_info`, and `.future_add_done_callback` help mask the difference between `asyncio.Future` and Tornado\'s previous ``Future`` implementation. + tornado.curl_httpclient
* Improved debug logging on Python 3.
* The ``time_info`` response attribute now includes ``appconnect`` in addition to other measurements.
* Closing a `.CurlAsyncHTTPClient` now breaks circular references that could delay garbage collection.
* The ``io_loop`` argument to the `.CurlAsyncHTTPClient` constructor has been removed. + tornado.gen
* ``tornado.gen.TimeoutError`` is now an alias for `tornado.util.TimeoutError`.
* Leak detection for ``Futures`` created by this module now attributes them to their proper caller instead of the coroutine machinery.
* Several circular references that could delay garbage collection have been broken up.
* On Python 3, `asyncio.Task` is used instead of the Tornado coroutine runner. This improves compatibility with some `asyncio` libraries and adds support for cancellation.
* The ``io_loop`` arguments to ``YieldFuture`` and `.with_timeout` have been removed. + tornado.httpclient
* The ``io_loop`` argument to all `.AsyncHTTPClient` constructors has been removed. + tornado.httpserver
* It is now possible for a client to reuse a connection after sending a chunked request.
* If a client sends a malformed request, the server now responds with a 400 error instead of simply closing the connection.
* ``Content-Length`` and ``Transfer-Encoding`` headers are no longer sent with 1xx or 204 responses (this was already true of 304 responses).
* When closing a connection to a HTTP/1.1 client, the ``Connection: close`` header is sent with the response.
* The ``io_loop`` argument to the `.HTTPServer` constructor has been removed.
* If more than one ``X-Scheme`` or ``X-Forwarded-Proto`` header is present, only the last is used. + tornado.httputil
* The string representation of `.HTTPServerRequest` objects (which are sometimes used in log messages) no longer includes the request headers.
* New function `.qs_to_qsl` converts the result of `urllib.parse.parse_qs` to name-value pairs. + tornado.ioloop
* ``tornado.ioloop.TimeoutError`` is now an alias for `tornado.util.TimeoutError`.
* `.IOLoop.instance` is now a deprecated alias for `.IOLoop.current`.
* `.IOLoop.install` and `.IOLoop.clear_instance` are deprecated.
* The ``IOLoop.initialized`` method has been removed.
* On Python 3, the `asyncio`-backed `.IOLoop` is always used and alternative `.IOLoop` implementations cannot be configured. `.IOLoop.current` and related methods pass through to `asyncio.get_event_loop`.
* `~.IOLoop.run_sync` cancels its argument on a timeout. This results in better stack traces (and avoids log messages about leaks) in native coroutines.
* New methods `.IOLoop.run_in_executor` and `.IOLoop.set_default_executor` make it easier to run functions in other threads from native coroutines (since `concurrent.futures.Future` does not support ``await``).
* ``PollIOLoop`` (the default on Python 2) attempts to detect misuse of `.IOLoop` instances across `os.fork`.
* The ``io_loop`` argument to `.PeriodicCallback` has been removed.
* It is now possible to create a `.PeriodicCallback` in one thread and start it in another without passing an explicit event loop.
* The ``IOLoop.set_blocking_signal_threshold`` and ``IOLoop.set_blocking_log_threshold`` methods are deprecated because they are not implemented for the `asyncio` event loop`. Use the ``PYTHONASYNCIODEBUG=1`` environment variable instead.
* `.IOLoop.clear_current` now works if it is called before any current loop is established. + tornado.iostream
* The ``io_loop`` argument to the `.IOStream` constructor has been removed.
* New method `.BaseIOStream.read_into` provides a minimal-copy alternative to `.BaseIOStream.read_bytes`.
* `.BaseIOStream.write` is now much more efficient for very large amounts of data.
* Fixed some cases in which ``IOStream.error`` could be inaccurate.
* Writing a `memoryview` can no longer result in \"BufferError: Existing exports of data: object cannot be re-sized\". + tornado.locks
* As a side effect of the ``Future`` changes, waiters are always notified asynchronously with respect to `.Condition.notify`. + tornado.netutil
* The default `.Resolver` now uses `.IOLoop.run_in_executor`. `.ExecutorResolver`, `.BlockingResolver`, and `.ThreadedResolver` are deprecated.
* The ``io_loop`` arguments to `.add_accept_handler`, `.ExecutorResolver`, and `.ThreadedResolver` have been removed.
* `.add_accept_handler` returns a callable which can be used to remove all handlers that were added.
* `.OverrideResolver` now accepts per-family overrides. + tornado.options
* Duplicate option names are now detected properly whether they use hyphens or underscores. + tornado.platform.asyncio
* `.AsyncIOLoop` and `.AsyncIOMainLoop` are now used automatically when appropriate; referencing them explicitly is no longer recommended.
* Starting an `.IOLoop` or making it current now also sets the `asyncio` event loop for the current thread. Closing an `.IOLoop` closes the corresponding `asyncio` event loop.
* `.to_tornado_future` and `.to_asyncio_future` are deprecated since they are now no-ops.
* `~.AnyThreadEventLoopPolicy` can now be used to easily allow the creation of event loops on any thread (similar to Tornado\'s prior policy). + tornado.platform.caresresolver
* The ``io_loop`` argument to `.CaresResolver` has been removed. + tornado.platform.twisted
* The ``io_loop`` arguments to ``TornadoReactor``, `.TwistedResolver`, and ``tornado.platform.twisted.install`` have been removed. + tornado.process
* The ``io_loop`` argument to the `.Subprocess` constructor and `.Subprocess.initialize` has been removed. + tornado.routing
* A default 404 response is now generated if no delegate is found for a request. + tornado.simple_httpclient
* The ``io_loop`` argument to `.SimpleAsyncHTTPClient` has been removed.
* TLS is now configured according to `ssl.create_default_context` by default. + tornado.tcpclient
* The ``io_loop`` argument to the `.TCPClient` constructor has been removed.
* `.TCPClient.connect` has a new ``timeout`` argument. + tornado.tcpserver
* The ``io_loop`` argument to the `.TCPServer` constructor has been removed.
* `.TCPServer` no longer logs ``EBADF`` errors during shutdown. + tornado.testing
* The deprecated ``tornado.testing.get_unused_port`` and ``tornado.testing.LogTrapTestCase`` have been removed.
* `.AsyncHTTPTestCase.fetch` now supports absolute URLs.
* `.AsyncHTTPTestCase.fetch` now connects to ``127.0.0.1`` instead of ``localhost`` to be more robust against faulty ipv6 configurations. + tornado.util
* `tornado.util.TimeoutError` replaces ``tornado.gen.TimeoutError`` and ``tornado.ioloop.TimeoutError``.
* `.Configurable` now supports configuration at multiple levels of an inheritance hierarchy. + tornado.web
* `.RequestHandler.set_status` no longer requires that the given status code appear in `http.client.responses`.
* It is no longer allowed to send a body with 1xx or 204 responses.
* Exception handling now breaks up reference cycles that could delay garbage collection.
* `.RedirectHandler` now copies any query arguments from the request to the redirect location.
* If both ``If-None-Match`` and ``If-Modified-Since`` headers are present in a request to `.StaticFileHandler`, the latter is now ignored. + tornado.websocket
* The C accelerator now operates on multiple bytes at a time to improve performance.
* Requests with invalid websocket headers now get a response with status code 400 instead of a closed connection.
* `.WebSocketHandler.write_message` now raises `.WebSocketClosedError` if the connection closes while the write is in progress.
* The ``io_loop`` argument to `.websocket_connect` has been removed.- Rebase patches:
