Convenience function. Connect to *address* (a 2-tuple ``(host, port)``) and return the socket object. Passing the optional *timeout* parameter will set the timeout on the socket instance before attempting to connect. If no *timeout* is supplied, the global default timeout setting returned by :func:`getdefaulttimeout` is used. If *source_address* is set it must be a tuple of (host, port) for the socket to bind as a source address before making the connection. An host of '' or port 0 tells the OS to use the default. �[z[]Nz!getaddrinfo returns an empty list) � startswith�strip�allowed_gai_family�socket� getaddrinfo� SOCK_STREAM�_set_socket_options�_GLOBAL_DEFAULT_TIMEOUT� settimeout�bind�connect�error�close)�addressr �source_address�socket_options�host�port�err�family�res�af�socktype�proto� canonname�sar �er r r �create_connection! s2 " r+ c C s2 | d k r d Sx | D] } | j | � q Wd S)N)� setsockopt)r �options�optr r r r Y s r c C s t j } t r t j } | S)z�This function is designed to work in the context of getaddrinfo, where family=socket.AF_UNSPEC is the default and will perform a DNS search for both IPv6 and IPv4 records.)r �AF_INET�HAS_IPV6� AF_UNSPEC)r# r r r r a s r c C s} d } d } t j � r d St j ri y/ t j t j � } | j | d f � d } Wn t k rh Yn X| ry | j � | S)z6 Returns True if the system can bind an IPv6 address.
