5.0.208 Apr 2018 08:45 minor feature: What's new in Tornado 5.0.1 Apr 7, 2018. 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. This loop. 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.
5.0.119 Mar 2018 03:18 minor feature: What's new in Tornado 5.0.1 Mar 18, 2018. 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.
5.0.006 Mar 2018 09:25 minor feature: What's new in Tornado 5.0 Mar 5, 2018. 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. - Cancella
4.5.308 Jan 2018 03:25 minor feature: What's new in Tornado 4.5.3 Jan 6, 2018. `tornado.curl_httpclient`. Improved delogging on Python 3. `tornado.httpserver`. `Content-Length` and `Transfer-Encoding` headers are no longer. sent with 1xx or 204 responses (this was already true of 304. responses). Reading chunked requests no longer leaves the connection in a broken. state. `tornado.iostream`. Writing a `memoryview` can no longer result in "BufferError: Existing exports of data: object cannot be re-sized". `tornado.options`. Duplicate option names are now detected properly whether they use. hyphens or underscores. `tornado.testing`. `.AsyncHTTPTestCase.fetch` now uses `127.0.0.1` instead of. `localhost`, improving compatibility with systems that have. partially-working ipv6 stacks. `tornado.web`. It is no longer allowed to send a body with 1xx or 204 responses. `tornado.websocket`. Requests with invalid websocket headers now get a response with. status code 400 instead of a connection.
4.5.228 Aug 2017 12:45 minor feature: What's new in Tornado 4.5.2 Aug 27, 2017. Tornado now sets the `FD_CLOEXEC` flag on all file descriptors it creates. This prevents hanging client connections and resource leaks when the `tornado.autoreload` module (or `Application(de=True)`) is used.
4.5.121 Apr 2017 19:05 minor feature: What's new in Tornado 4.5 Apr 16, 2017. `tornado.log`. Improved detection of libraries for colorized logging. `tornado.httputil`. `.url_concat` once again treats None as equivalent to an empty sequence.
4.5.017 Apr 2017 09:25 minor feature: What's new in Tornado 4.5 Apr 16, 2017. Backwards-compatibility warning. The `tornado.websocket` module now imposes a limit on the size of incoming. messages, which defaults to 10MiB. New module. `tornado.routing` provides a more flexible routing system than the one built in. to `.Application`. General changes. Reduced the number of circular references, reducing memory usage and. improving performance. `tornado.auth`. The `tornado.auth` module has been updated for compatibility with `a. change to Facebook's access_token endpoint. lt;#1977 gt;`_. This includes both. the changes initially released in Tornado 4.4.3 and an additional change. to support the ``session_expires` field in the new format. The `session_expires` field is currently a string; it should be accessed. as `int(user 'session_expires' )` because it will change from a string to. an int in Tornado 5.0. `tornado.autoreload`. Autoreload is now compatible with the `asyncio` event loop. Autoreload no longer attempts to the `.IOLoop` and all registered. file descriptors before restarting; it relies on the `CLOEXEC` flag. being set instead. `tornado.concurrent`. Suppressed some "'NoneType' object not callback" messages that could. be logged at shutdown. `tornado.gen`. `yield None` is now equivalent to `yield gen.moment`. ` tornado.gen.moment` is deprecated. This improves compatibility with. `asyncio`. an in which a generator object could be garbage. collected prematurely (most often when weak references are used. New function `.is_coroutine_function` identifies functions wrapped. by `.coroutine` or `.engine`. `tornado.http1connection`. The `Transfer-Encoding` header is now parsed case-insensitively. `tornado.httpclient`. `SimpleAsyncHTTPClient` now follows 308 redirects. `CurlAsyncHTTPClient` will no longer accept protocols other than. `http` and `https`. To override this, set `pycurl.PROTOCOLS`. and `pycurl.REDIR_PROTOCOLS` i
4.4.331 Mar 2017 06:05 minor feature: What's new in Tornado 4.4.3 Mar 30, 2017. The `tornado.auth` module has been updated for compatibility with `a. change to Facebook's access_token endpoint. lt;#1977 gt;`_.
4.4.202 Oct 2016 19:25 minor feature: What's new in Tornado 4.4.2 Oct 1, 2016. Security. A difference in cookie parsing between Tornado and web browsers. (especially when combined with Google Analytics) could allow an. Attacker to set arbitrary cookies and bypass XSRF protection. The. Cookie parser has been rewritten to this attack. Backwards-compatibility notes. Cookies containing certain special characters (in particular semicolon. And square brackets) are now parsed differently. If the cookie header contains a combination of valid and invalid cookies. The valid ones will be returned (older versions of Tornado would reject the. Entire header for a single invalid cookie).
4.4.125 Jul 2016 05:25 minor feature: What's new in Tornado 4.4.1 Jul 23, 2016. `tornado.web`. a regression in Tornado 4.4 which caused URL regexes. Containing backslash escapes outside capturing groups to be. Rejected.
4.4.017 Jul 2016 14:45 minor feature: What's new in Tornado 4.4 Jul 15, 2016. General. Tornado now requires Python 2.7 or 3.3+; versions 2.6 and 3.2 are no. longer supported. Pypy3 is still supported even though its latest. release is mainly based on Python 3.2. The `monotonic lt;https://pypi.python.org/pypi/monotonic gt;`_ package is. now supported as an alternative to `Monotime. lt;https://pypi.python.org/pypi/Monotime gt;`_ for monotonic clock support. on Python 2. `tornado.curl_httpclient`. Failures in `_curl_setup_request` no longer cause the. `max_clients` pool to be exhausted. Non-ascii header values are now handled correctly. `tornado.gen`. `.with_timeout` now accepts any yieldable object (except. `.YieldPoint`), not just `tornado.concurrent.Future`. `tornado.httpclient`. The errors raised by timeouts now indicate what state the request. was in; the error message is no longer simply "599 Timeout". Calling `repr` on a `tornado.httpclient.HTTPError` no longer raises. an error. `tornado.httpserver`. Int-like enums (including `http.HTTPStatus`) can now be used as. status codes. Responses with status code `204 No Content` no longer emit a. `Content-Length: 0` header. `tornado.ioloop`. Improved performance when there are large numbers of active timeouts. `tornado.netutil`. All included `.Resolver` implementations raise `IOError` (or a. subclass) for any resolution failure. `tornado.options`. Options can now be modified with subscript syntax in addition to. attribute syntax. The special variable `__file__` is now available inside config files. `tornado.simple_httpclient`. HTTP/1.0 (not 1.1) responses without a `Content-Length` header now. work correctly. `tornado.tcpserver`. `.TCPServer.bind` now accepts a `reuse_port` argument. `tornado.testing`. Test sockets now always use `127.0.0.1` instead of `localhost`. This avoids conflicts when the automatically-assigned port is. available on IPv4 but not IPv6, o
4.4.0b109 Jul 2016 13:45 minor feature: Cast start_line.code to an integer. Make __getitem__ and __setitem__ mirror behavior of __getattr__ and _?. Unset executable bit. Use `127.0.0.1` when binding test server socket. Bump master version number to 4.4.dev1. Drop Python 2.6 support. Drop support for Python 3.2. Invert _unicode_literal to switch back to real literals. Convert all uses of t.util.u() to real unicode literals. Remove the u() function and a few uses the script missed. Streamline travis-ci build. Add monotonic as an alternative to Monotime. CurlAsyncHTTPClient: free_list starvation if setup fails. test failure to set up curl http requests. httpclient: Document that HTTPError is not the only possible error. Correct version change in Lock docstring. Missing hint in documentation. Add reuse_port flag to TCPServer.bind method. Use super() to call super "__init__()". Update options.py. Update options.py. Update options.py. logging when running tests with twisted installed. Use super() to call super "__init__()". make kwargs always work in AsyncHTTPClient.fetch(). add more detailed information to HTTP Timeout error raised by SimpleA?. refractor test_connect_timeout with a never finished future. replace BlockingResolver with Resolver and update timeout value becau?. raise ValueError if supply both a request object and kwargs. reverse_url should unescape regex string. Update hints for popular operating systems. re_unescape with a much simpler method; raise TypeError on invalid input. Move towards mypy-friendly patterns. Added SVG to compressible mime types. Add a test for path arguments in websockets. Improve docs of URLSpec capturing groups. Improve grammar in docs. Add defaults to template.ParseError arguments. Define `httpclient.HTTPError.__repr__`.

Add a test for HTTPError.__str__ when it uses httputils.
4.3.007 Nov 2015 13:25 minor feature: Tornado 4.3 Nov 6, 2015. Highlights. The new async/await keywords in Python 3.5 are supported. In most cases. `async def` can be used in place of the `@gen.coroutine` decorator. Inside a function defined with `async def`, use `await` instead of. `yield` to wait on an asynchronous operation. Coroutines defined with. async/await will be faster than those defined with `@gen.coroutine` and. `yield`, but do not support some features including `.Callback`/`.Wait` or. the ability to yield a Twisted `Deferred`. See :ref:`the users'. guide lt;native_coroutines gt;` for more. The async/await keywords are also available when compiling with Cython in. older versions of Python. Deprecation notice. This will be the last release of Tornado to support Python 2.6 or 3.2. Note that PyPy3 will continue to be supported even though it implements. a mix of Python 3.2 and 3.3 features. Installation. Tornado has several new dependencies: `ordereddict` on Python 2.6. `singledispatch` on all Python versions prior to 3.4 (This was an. optional dependency in prior versions of Tornado, and is now. mandatory), and `backports_abc gt;=0.4` on all versions prior to. 3.5. These dependencies will be installed automatically when installing. with `pip` or `setup.py install`. These dependencies will not. be required when running on Google App Engine. Binary wheels are provided for Python 3.5 on Windows (32 and 64 bit). `tornado.auth`. New method `.OAuth2Mixin.oauth2_request` can be used to make authenticated. requests with an access token. Now compatible with callbacks that have been compiled with Cython. `tornado.autoreload`. an with the autoreload command-line wrapper in which. imports would be incorrectly interpreted as relative. `tornado.curl_httpclient`. parsing of multi-line headers. `allow_nonstandard_methods=True` now bypasses body sanity checks. in the same way as in `simple_httpclient`. The `PATCH` method now allows a body wi
4.3.0b225 Oct 2015 07:45 minor feature: Return HTTPServer in Application.listen. PEP8 docs/conf.py:91:1: E122 continuation line missing indentatio?. Check for Content-Length and Transfer-Encoding. Restrict header check to SimpleAsyncHTTPClient. Make test_root_static_path more robust. Added xsrf_cookie_kwargs to control xsrf cookie settings. Update tests and docs for recent changes.

Consistently format the three "Hello, world" examples (docs and README). Clarify the role and meaning of self.fetch() in AsyncHTTPTestCase. Tie the example for AsyncHTTPTestCase to real code. Clear __package__ in script run by autoreload CLI. Document StaticFileHandler's default_filename option. Introduce OAuth2Mixin.oauth2_request. Update outdated comment. Add Google OAuth2 user info request. unicode syntax for Python 3. Remove _OAUTH_USERINFO_URL. doctests. Merge branch 'pr1456'. Add filename to template.ParseError messages. Use unittest.mock in test_gaierror. Make dashes and underscores interchangeable in option names. Support pickling of HTTPHeaders. Update travis-ci.org URL in comment. Reduce logging of errors inside IOStream (especially SSLError). Relax a test for SSL errors in start_tls. Add support for UTF-16 and UTF-8-with-BOM to CSV locale. Start next-release notes. Move compress_whitespace setting from template writer to reader. Add Loader parameter to control whitespace mode. Introduce `oneline` template whitespace mode. Add ` whitespace ` template directive. Merge branch 'branch4.2'. Update copyright line in docs. Remove an useless line. incorrect check in IOLoop(make_current=True). Remove arbitrary cap on length of outgoing headers. Correctly clear IOLoop.current() after TwistedIOLoop exits. Restore IOLoop.current() when AsyncIOLoop exits. test Content-Type for static compressed files. Content-Type for compressed StaticFileHandler file. Remove hidden testsetup blocks from otherwise self-contained doctests. Reduce default compression to level 6; raise min compressible length. Add docs about calling coroutines. Mention async/await in coroutine docs. Support other yieldables in `yield list`/`multi_future`. Implement the async context manager protocol in tornado.locks. Reduce duplication in exec-based tests. Support async i
4.2.118 Jul 2015 23:05 minor bugfix: This release fixes a path traversal vulnerability in `.StaticFileHandler`, in which files whose names *started with the `static_path` directory but were not actually *in that directory could be accessed.
4.2.027 May 2015 15:25 minor feature: `SSLIOStream.connect` and `.IOStream.start_tls` now validate certificates by default. Certificate validation will now use the system CA root certificates instead of `certifi` when possible (i.e. Python 2.7.9+ or 3.4+). This includes. `.IOStream` and `simple_httpclient`, but not `curl_httpclient`. The default SSL configuration has become stricter, using. `ssl.create_default_context` where available on the client side. (On the server side, applications are encouraged to migrate from the. `ssl_options` dict-based API to pass an `ssl.SSLContext` instead). The deprecated classes in the `tornado.auth` module, `GoogleMixin`,. `FacebookMixin`, and `FriendFeedMixin` have been removed. New modules:`tornado.locks` and `tornado.queues`. These modules provide classes for coordinating coroutines, merged from. `Toro lt;http:/toro.readthedocs.org gt;`_. To port your code from Toro's queues to Tornado 4.2, import `.Queue`,. `.PriorityQueue`, or `.LifoQueue` from `tornado.queues` instead of from. `toro`. Use `.Queue` instead of Toro's `JoinableQueue`. In Tornado the methods. ` .Queue.join` and ` .Queue.task_done` are available on all queues, not on a. special `JoinableQueue`. Tornado queues raise exceptions specific to Tornado instead of reusing. exceptions from the Python standard library. Therefore instead of catching the standard `queue.Empty` exception from `.Queue.get_nowait`, catch the special `tornado.queues.QueueEmpty` exception,. and instead of catching the standard `queue.Full` from `.Queue.get_nowait`, catch `tornado.queues.QueueFull`. To port from Toro's locks to Tornado 4.2, import `.Condition`, `.Event`,. `.Semaphore`, `.BoundedSemaphore`, or `.Lock` from `tornado.locks`. instead of from `toro`. Toro's `Semaphore.wait` allowed a coroutine to wait for the semaphore to. be unlocked *without acquiring it. This encouraged unorthodox patterns; in Tornado, just use ` .Semaphore.acquire`. Toro's `Event.wait` raised a `Timeout` exception after a timeo

Add tornado.locks.Condition. _on_close_called is set to True (was always False). Document the limitations of read_until_close(streaming_callback=). Update ssl_options docs to use SSLContext. Validate SSL certs by default at the IOStream level. Add ssl_options argument for simple_httpclient. Document that allow_ipv6 is now true in simple_httpclient. Reuse a global SSLContext by default in simple_httpclient. Fix tests on py26. Disable SSL compression on py32-33. Fix docs and relax a test. Unused imports in locks.py. Add tornado.locks.Event.

Make "certifi" optional on py34. Fix multiple calls to Event.clear. Import unittest2 in locks_test if needed. Fix SSLIOStream in Python 3.5a1. Fix web_test for python 3.5a1. Remove long-forgotten (and overly pessimistic) README. Fix simple typo in httpclient exception message. Simpler markup in Event.wait docstring. Rename TestEvent to EventTest. Add tornado.locks.Semaphore
4.1.009 Feb 2015 15:05 minor feature: If a Future contains an exception but that exception is never examined or re-raised (e.g. by yielding the Future), a stack trace will be logged when the Future is garbage-collected. New class tornado.gen.WaitIterator provides a way to iterate over Futures in the order they resolve. The tornado.websocket module now supports compression via the permessage-deflate extension. Override WebSocketHandler.get_compression_options to enable on the server side, and use the compression_options keyword argument to websocket_connect on the client side. When the appropriate packages are installed, it is possible to yield asyncio.Future or Twisted Defered objects in Tornado coroutines.

4.0.016 Jul 2014 09:06 major feature: IPv6 is now supported, and the TCPClient creates conections with non-blocking DNS and SSL handshaking. Larger file uploads are handled by web.stream_request_body now with less memory usage. Coroutines were speed up and are used extensively throughout Tornado itself. More methods now return Futures, including most IOStream methods and RequestHandler.flush. Many user-overridden methods are now allowed to return a Future for flow control. HTTP-related code is now shared between the tornado.httpserver, tornado.simple_httpclient and tornado.wsgi modules, making support for features such as chunked and gzip encoding more consistent. HTTPServer now uses delegation instead of a single-callback interface.
