Update to 4.2:

What's new in Tornado 4.2
=========================

May 26, 2015
------------

Backwards-compatibility notes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

* ``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 <http://toro.readthedocs.org>`_.

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 timeout. In
Tornado, `.Event.wait` raises `tornado.gen.TimeoutError`.

Toro's ``Condition.wait`` also raised ``Timeout``, but in Tornado, the `.Future`
returned by `.Condition.wait` resolves to False after a timeout::

    @gen.coroutine
    def await_notification():
        if not (yield condition.wait(timeout=timedelta(seconds=1))):
            print('timed out')
        else:
            print('condition is true')

In lock and queue methods, wherever Toro accepted ``deadline`` as a keyword
argument, Tornado names the argument ``timeout`` instead.

Toro's ``AsyncResult`` is not merged into Tornado, nor its exceptions
``NotReady`` and ``AlreadySet``. Use a `.Future` instead. If you wrote code like
this::

    from tornado import gen
    import toro

    result = toro.AsyncResult()

    @gen.coroutine
    def setter():
        result.set(1)

    @gen.coroutine
    def getter():
        value = yield result.get()
        print(value)  # Prints "1".

Then the Tornado equivalent is::

    from tornado import gen
    from tornado.concurrent import Future

    result = Future()

    @gen.coroutine
    def setter():
        result.set_result(1)

    @gen.coroutine
    def getter():
        value = yield result
        print(value)  # Prints "1".

`tornado.autoreload`
~~~~~~~~~~~~~~~~~~~~

* Improved compatibility with Windows.
* Fixed a bug in Python 3 if a module was imported during a reload check.

`tornado.concurrent`
~~~~~~~~~~~~~~~~~~~~

* `.run_on_executor` now accepts arguments to control which attributes
  it uses to find the `.IOLoop` and executor.

`tornado.curl_httpclient`
~~~~~~~~~~~~~~~~~~~~~~~~~

* Fixed a bug that would cause the client to stop processing requests
  if an exception occurred in certain places while there is a queue.

`tornado.escape`
~~~~~~~~~~~~~~~~

* `.xhtml_escape` now supports numeric character references in hex
  format (``&#x20;``)

`tornado.gen`
~~~~~~~~~~~~~

* `.WaitIterator` no longer uses weak references, which fixes several
  garbage-collection-related bugs.
* `tornado.gen.Multi` and `tornado.gen.multi_future` (which are used when
  yielding a list or dict in a coroutine) now log any exceptions after the
  first if more than one `.Future` fails (previously they would be logged
  when the `.Future` was garbage-collected, but this is more reliable).
  Both have a new keyword argument ``quiet_exceptions`` to suppress
  logging of certain exception types; to use this argument you must
  call ``Multi`` or ``multi_future`` directly instead of simply yielding
  a list.
* `.multi_future` now works when given multiple copies of the same `.Future`.
* On Python 3, catching an exception in a coroutine no longer leads to
  leaks via ``Exception.__context__``.

`tornado.httpclient`
~~~~~~~~~~~~~~~~~~~~

* The ``raise_error`` argument now works correctly with the synchronous
  `.HTTPClient`.
* The synchronous `.HTTPClient` no longer interferes with `.IOLoop.current()`.

`tornado.httpserver`
~~~~~~~~~~~~~~~~~~~~

* `.HTTPServer` is now a subclass of `tornado.util.Configurable`.

`tornado.httputil`
~~~~~~~~~~~~~~~~~~

* `.HTTPHeaders` can now be copied with `copy.copy` and `copy.deepcopy`.

`tornado.ioloop`
~~~~~~~~~~~~~~~~

* The `.IOLoop` constructor now has a ``make_current`` keyword argument
  to control whether the new `.IOLoop` becomes `.IOLoop.current()`.
* Third-party implementations of `.IOLoop` should accept ``**kwargs``
  in their `~.IOLoop.initialize` methods and pass them to the superclass
  implementation.
* `.PeriodicCallback` is now more efficient when the clock jumps forward
  by a large amount.

`tornado.iostream`
~~~~~~~~~~~~~~~~~~

* ``SSLIOStream.connect`` and `.IOStream.start_tls` now validate certificates
  by default.
* New method `.SSLIOStream.wait_for_handshake` allows server-side applications
  to wait for the handshake to complete in order to verify client certificates
  or use NPN/ALPN.
* The `.Future` returned by ``SSLIOStream.connect`` now resolves after the
  handshake is complete instead of as soon as the TCP connection is
  established.
* Reduced logging of SSL errors.
* `.BaseIOStream.read_until_close` now works correctly when a
  ``streaming_callback`` is given but ``callback`` is None (i.e. when
  it returns a `.Future`)

`tornado.locale`
~~~~~~~~~~~~~~~~

* New method `.GettextLocale.pgettext` allows additional context to be
  supplied for gettext translations.

`tornado.log`
~~~~~~~~~~~~~

* `.define_logging_options` now works correctly when given a non-default
  ``options`` object.

`tornado.process`
~~~~~~~~~~~~~~~~~

* New method `.Subprocess.wait_for_exit` is a coroutine-friendly
  version of `.Subprocess.set_exit_callback`.

`tornado.simple_httpclient`
~~~~~~~~~~~~~~~~~~~~~~~~~~~

* Improved performance on Python 3 by reusing a single `ssl.SSLContext`.
* New constructor argument ``max_body_size`` controls the maximum response
  size the client is willing to accept. It may be bigger than
  ``max_buffer_size`` if ``streaming_callback`` is used.

`tornado.tcpserver`
~~~~~~~~~~~~~~~~~~~

* `.TCPServer.handle_stream` may be a coroutine (so that any exceptions
  it raises will be logged).

`tornado.util`
~~~~~~~~~~~~~~

* `.import_object` now supports unicode strings on Python 2.
* `.Configurable.initialize` now supports positional arguments.

`tornado.web`
~~~~~~~~~~~~~

* Key versioning support for cookie signing. ``cookie_secret`` application
  setting can now contain a dict of valid keys with version as key. The
  current signing key then must be specified via ``key_version`` setting.
* Parsing of the ``If-None-Match`` header now follows the RFC and supports
  weak validators.
* Passing ``secure=False`` or ``httponly=False`` to
  `.RequestHandler.set_cookie` now works as expected (previously only the
  presence of the argument was considered and its value was ignored).
* `.RequestHandler.get_arguments` now requires that its ``strip`` argument
  be of type bool. This helps prevent errors caused by the slightly dissimilar
  interfaces between the singular and plural methods.
* Errors raised in ``_handle_request_exception`` are now logged more reliably.
* `.RequestHandler.redirect` now works correctly when called from a handler
  whose path begins with two slashes.
* Passing messages containing ``%`` characters to `tornado.web.HTTPError`
  no longer causes broken error messages.

`tornado.websocket`
~~~~~~~~~~~~~~~~~~~

* The ``on_close`` method will no longer be called more than once.
* When the other side closes a connection, we now echo the received close
  code back instead of sending an empty close frame.
