"Happy Eyeballs" is documented in RFC6555 as the recommended practice for when both IPv4 and IPv6 addresses are available. In this implementation, we partition the addresses by family, and make the first connection attempt to whichever address was returned first by ``getaddrinfo``. If that connection fails or times out, we begin a connection in parallel to the first address of the other family. If there are additional failures we retry with other addresses, keeping one connection attempt per family in flight at a time. http://tools.ietf.org/html/rfc6555 addrinfoconnectFuture[IOStream]returnNc&tj|_||_t |_d|_d|_d|_t||_ | |\|_ |_ t|_dSN)rcurrentio_looprrfuturetimeoutconnect_timeout last_errorlen remainingsplit primary_addrssecondary_addrssetstreams)selfrrs Q/var/www/html/test/jupyter/venv/lib/python3.11/site-packages/tornado/tcpclient.py__init__z_Connector.__init__;sz~''   HH  #X37::h3G3G0D0uu cg}g}|dd}|D]:\}}||kr|||f#|||f;||fS)aPartition the ``addrinfo`` list by address family.

Asynchronously returns an `.IOStream` (or `.SSLIOStream` if ``ssl_options`` is not None). Using the ``source_ip`` kwarg, one can specify the source IP address to use when establishing the connection. In case the user needs to resolve and use a specific interface, it has to be handled outside of Tornado as this depends very much on the platform. Raises `TimeoutError` if the input future does not complete before ``timeout``, which may be specified in any form allowed by `.IOLoop.add_timeout` (i.e. a `datetime.timedelta` or an absolute time relative to `.IOLoop.time`) Similarly, when the user requires a certain source port, it can be specified using the ``source_port`` arg. .. versionchanged:: 4.5 Added the ``source_ip`` and ``source_port`` arguments. .. versionchanged:: 5.0 Added the ``timeout`` argument.
