This function implements the stateless version of the Happy Eyeballs algorithm (RFC 6555). If ``address`` is a host name that resolves to multiple IP addresses, each one is tried until one connection attempt succeeds. If the first attempt does not connected within 250 milliseconds, a second attempt is started using the next address in the list, and so on. On IPv6 enabled systems, an IPv6 address (if available) is tried first. When the connection has been established, a TLS handshake will be done if either ``ssl_context`` or ``tls_hostname`` is not ``None``, or if ``tls`` is ``True``. :param remote_host: the IP address or host name to connect to :param remote_port: port on the target host to connect to :param local_host: the interface address or name to bind the socket to before connecting :param tls: ``True`` to do a TLS handshake with the connected stream and return a :class:`~anyio.streams.tls.TLSStream` instead :param ssl_context: the SSL context object to use (if omitted, a default context is created) :param tls_standard_compatible: If ``True``, performs the TLS shutdown handshake before closing the stream and requires that the server does this as well. Otherwise, :exc:`~ssl.SSLEOFError` may be raised during reads from the stream. Some protocols, such as HTTP, require this option to be ``False``. See :meth:`~ssl.SSLContext.wrap_socket` for details. :param tls_hostname: host name to check the server certificate against (defaults to the value of ``remote_host``) :param happy_eyeballs_delay: delay (in seconds) before starting the next connection attempt :return: a socket stream object if no TLS handshake was done, otherwise a TLS stream :raises OSError: if the connection attempt fails Nr*eventr-c szKz |IdH}Wnty+}z|WYd}~W|dSd}~wwdur8|jn|IdHW|dSW|dS|wr/)r3OSErrorappendset cancel_scopecancelaclose)r*r8streamexcasynclibconnected_stream local_addressoserrorsr+tgr0r2 try_connects      z connect_tcp..try_connectrfamilytypeFTrzAll connection attempts failed) server_sidehostnamer'standard_compatible)strrrsocket AF_UNSPEC getaddrinfor ValueError SOCK_STREAMAF_INET6insertAF_INETr: isinstancer compressedr enumerate start_soonr waitlenExceptionGroupr9rwrap BaseExceptionr)r*r+r&r5r'r(r,r)rGrIgai_res_ target_hostaddr_objv6_foundv4_found target_addrsafrestsaiaddrr8causer0rAr2r3usv*$      (    pathz PathLike[str]cs tt|}t|IdHS)z Connect to the given UNIX socket.
