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�socketZ getaddrinfoZ SOCK_STREAM�_set_socket_options�_GLOBAL_DEFAULT_TIMEOUTZ settimeout�bindZconnect�error�close)Zaddressr Zsource_addressZsocket_options�hostZport�err�family�resZafZsocktype�protoZ canonnameZsar �er r r �create_connection$ s2 r c C s( |d kr d S x|D ]}| j |� qW d S )N)Z setsockopt)r Zoptions�optr r r r X s r c C s t j} trt 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 ZAF_INET�HAS_IPV6Z AF_UNSPEC)r r r r r ` s r c C sV d}d}t jrFy"t j t j�}|j| df� d}W n tk rD Y nX |rR|j� |S )z6 Returns True if the system can bind an IPv6 address.
