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:`socket.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[]N�idna�'z', label empty or too longz!getaddrinfo returns an empty list)� startswith�strip�allowed_gai_family�encode� UnicodeErrorr �socket� getaddrinfo� SOCK_STREAM�_set_socket_optionsr � settimeout�bind�connect�OSError�close)r r r r �host�port�err�family�res�af�socktype�proto� canonname�sa�sock�_r r r �create_connection sD � ��r4 r2 �options�Nonec C s$ |d u rd S |D ]}| j |� qd S )N)� setsockopt)r2 r5 �optr r r r" ] s �r" �socket.AddressFamilyc 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 �AF_INET�HAS_IPV6� AF_UNSPEC)r+ r r r r g s r r( �strc C sT d}d}t jr"zt � t j�}|�| df� d}W n ty!
