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. t [s []s! getaddrinfo returns an empty listN( t startswitht stripR t allowed_gai_familyt sockett getaddrinfot SOCK_STREAMt _set_socket_optionst _GLOBAL_DEFAULT_TIMEOUTt settimeoutt bindt connectt errort close( t addressR t source_addresst socket_optionst hostt portt errt familyt rest aft socktypet protot canonnamet saR t e( ( sG /usr/lib/python2.7/site-packages/pip/_vendor/urllib3/util/connection.pyt create_connection$ s2 " c C@ s2 | d k r d Sx | D] } | j | � q Wd S( N( R t setsockopt( R t optionst opt( ( sG /usr/lib/python2.7/site-packages/pip/_vendor/urllib3/util/connection.pyR X s c C@ s t j } t r t j } n | S( s� 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 t AF_INETt HAS_IPV6t AF_UNSPEC( R!
