To use `TCPServer`, define a subclass which overrides the `handle_stream`
method.
To make this server serve SSL traffic, send the ``ssl_options`` keyword
argument with an `ssl.SSLContext` object. For compatibility with older
versions of Python ``ssl_options`` may also be a dictionary of keyword
arguments for the `ssl.wrap_socket` method.::
ssl_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
ssl_ctx.load_cert_chain(os.path.join(data_dir, "mydomain.crt"),
os.path.join(data_dir, "mydomain.key"))
TCPServer(ssl_options=ssl_ctx)
`TCPServer` initialization follows one of three patterns:
1. `listen`: simple single-process::
server = TCPServer()
server.listen(8888)
IOLoop.current().start()
2. `bind`/`start`: simple multi-process::
server = TCPServer()
server.bind(8888)
server.start(0) # Forks multiple sub-processes
IOLoop.current().start()
When using this interface, an `.IOLoop` must *not* be passed
to the `TCPServer` constructor. `start` will always start
the server on the default singleton `.IOLoop`.
3. `add_sockets`: advanced multi-process::
sockets = bind_sockets(8888)
tornado.process.fork_processes(0)
server = TCPServer()
server.add_sockets(sockets)
IOLoop.current().start()
The `add_sockets` interface is more complicated, but it can be
used with `tornado.process.fork_processes` to give you more
flexibility in when the fork happens. `add_sockets` can
also be used in single-process servers if you want to create
your listening sockets in some way other than
`~tornado.netutil.bind_sockets`.

This method may be called more than once to listen on multiple ports.
`listen` takes effect immediately; it is not necessary to call
`TCPServer.start` afterwards. It is, however, necessary to start
the `.IOLoop`.

The ``sockets`` parameter is a list of socket objects such as
those returned by `~tornado.netutil.bind_sockets`.
`add_sockets` is typically used in combination with that
method and `tornado.process.fork_processes` to provide greater
control over the initialization of a multi-process server.

To start the server, call `start`. If you want to run this server
in a single process, you can call `listen` as a shortcut to the
sequence of `bind` and `start` calls.
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>`.
This method may be called multiple times prior to `start` to listen
on multiple ports or interfaces.

By default, we run the server in this process and do not fork any
additional child process.
If num_processes is ``None`` or <= 0, we detect the number of cores
available on this machine and fork that number of child
processes. If num_processes is given and > 1, we fork that
specific number of sub-processes.
Since we use processes and not threads, there is no shared memory
between any server code.
Note that multiple processes are not compatible with the autoreload
module (or the ``autoreload=True`` option to `tornado.web.Application`
which defaults to True when ``debug=True``).
When using multiple processes, no IOLoops can be created or
referenced until after the call to ``TCPServer.start(n)``.

This method may be a coroutine; if so any exceptions it raises
asynchronously will be logged. Accepting of incoming connections
will not be blocked by this coroutine.
If this `TCPServer` is configured for SSL, ``handle_stream``
may be called before the SSL handshake has completed. Use
`.SSLIOStream.wait_for_handshake` if you need to verify the client's
certificate or use NPN/ALPN.
