}|j#|� |j$|� q~W |S )a Creates listening sockets bound to the given port and address.
Returns a list of socket objects (multiple sockets are returned if
the given address maps to multiple IP addresses, which is most common
for mixed IPv4 and IPv6 use).
Address may be either an IP address or hostname. If it's a hostname,
the server will listen on all IP addresses associated with the
name. Address may be an empty string or None to listen on all
available interfaces. Family may be set to either `socket.AF_INET`
or `socket.AF_INET6` to restrict to IPv4 or IPv6 addresses, otherwise
both will be used if available.
The ``backlog`` argument has the same meaning as for
`socket.listen() <socket.socket.listen>`.
``flags`` is a bitmask of AI_* flags to `~socket.getaddrinfo`, like
``socket.AI_PASSIVE | socket.AI_NUMERICHOST``.
``reuse_port`` option sets ``SO_REUSEPORT`` option for every socket
in the list. If your platform doesn't support this option ValueError will
be raised.

When a connection is accepted, ``callback(connection, address)`` will
be run (``connection`` is a socket object, and ``address`` is the
address of the other end of the connection). Note that this signature
is different from the ``callback(fd, events)`` signature used for
`.IOLoop` handlers.
A callable is returned which, when called, will remove the `.IOLoop`
event handler and stop processing further incoming connections.

The ``io_loop`` argument (deprecated since version 4.1) has been removed.

A callable is returned (``None`` was returned before).

�ResolveraM Configurable asynchronous DNS resolver interface.
By default, a blocking implementation is used (which simply calls
`socket.getaddrinfo`). An alternative implementation can be
chosen with the `Resolver.configure <.Configurable.configure>`
class method::
Resolver.configure('tornado.netutil.ThreadedResolver')
The implementations of this interface included with Tornado are
* `tornado.netutil.DefaultExecutorResolver`
* `tornado.netutil.BlockingResolver` (deprecated)
* `tornado.netutil.ThreadedResolver` (deprecated)
* `tornado.netutil.OverrideResolver`
* `tornado.platform.twisted.TwistedResolver`
* `tornado.platform.caresresolver.CaresResolver`
.. versionchanged:: 5.0
The default implementation has changed from `BlockingResolver` to
`DefaultExecutorResolver`.

The ``host`` argument is a string which may be a hostname or a
literal IP address.
Returns a `.Future` whose result is a list of (family,
address) pairs, where address is a tuple suitable to pass to
`socket.connect <socket.socket.connect>` (i.e. a ``(host,
port)`` pair for IPv4; additional fields may be present for
IPv6). If a ``callback`` is passed, it will be run with the
result as an argument when it is complete.
:raises IOError: if the address cannot be resolved.
.. versionchanged:: 4.4
Standardized all implementations to raise `IOError`.
.. versionchanged:: 6.0 The ``callback`` argument was removed.
Use the returned awaitable object instead.

Use this instead of `ThreadedResolver` when you require additional
control over the executor being used.

``close_resolver=False``; use this if you want to reuse the same
executor elsewhere.

�ThreadedResolvera� Multithreaded non-blocking `Resolver` implementation.
Requires the `concurrent.futures` package to be installed
(available in the standard library since Python 3.2,
installable with ``pip install futures`` in older versions).
The thread pool size can be configured with::
Resolver.configure('tornado.netutil.ThreadedResolver',
num_threads=10)
.. versionchanged:: 3.1
All ``ThreadedResolvers`` share a single thread pool, whose
size is set by the first one to be created.

of this class.

This can be used to make local DNS changes (e.g. for testing)
without modifying system-wide settings.
The mapping can be in three formats::
{
# Hostname to host or ip
"example.com": "127.0.1.1",
# Host+port to host+port
("login.example.com", 443): ("localhost", 1443),
# Host+port+address family to host+port
("login.example.com", 443, socket.AF_INET6): ("::1", 1443),
}
.. versionchanged:: 5.0
Added support for host-port-family triplets.

|S ) a� Try to convert an ``ssl_options`` dictionary to an
`~ssl.SSLContext` object.
The ``ssl_options`` dictionary contains keywords to be passed to
`ssl.wrap_socket`. In Python 2.7.9+, `ssl.SSLContext` objects can
be used instead. This function converts the dict form to its
`~ssl.SSLContext` equivalent, and may be used when a component which
accepts both forms needs to upgrade to the `~ssl.SSLContext` version
to use features like SNI or NPN.

`~ssl.SSLContext` method or the `ssl` module function as
appropriate).
