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. ú[z[]Nz!getaddrinfo returns an empty list) Ú startswithÚstripÚallowed_gai_familyrÚ getaddrinfoÚ SOCK_STREAMÚ_set_socket_optionsÚ_GLOBAL_DEFAULT_TIMEOUTÚ settimeoutÚbindÚconnectr Úclose)ÚaddressÚtimeoutÚsource_addressZsocket_optionsÚhostÚportÚerrÚfamilyÚresÚafÚsocktypeÚprotoÚ canonnameÚsarÚerrrÚcreate_connection3s2  "       r-cCs2|dkrdSx|D]}|j|ŒqWdS)N)Ú setsockopt)rÚoptionsÚoptrrrrgs  rcCstj}trtj}n|S)z³This 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.)rÚAF_INETÚHAS_IPV6Ú AF_UNSPEC)r%rrrros  rc Cssd}d}tjr\y/tjtjƒ}|j|dfƒd}Wq\tk rXYq\Xn|ro|jƒn|S)z6 Returns True if the system can bind an IPv6 address.
