This is a non-blocking and non-threaded resolver. It may not produce the same results as the system resolver, but can be used for non-blocking resolution when threads cannot be used. ``pycares`` will not return a mix of ``AF_INET`` and ``AF_INET6`` when ``family`` is ``AF_UNSPEC``, so it is only recommended for use in ``AF_INET`` (i.e. IPv4). This is the default for ``tornado.simple_httpclient``, but other libraries may default to ``AF_UNSPEC``. .. versionchanged:: 5.0 The ``io_loop`` argument (deprecated since version 4.1) has been removed. .. deprecated:: 6.2 This class is deprecated and will be removed in Tornado 7.0. Use the default thread-based resolver instead. �returnNc C s$ t �� | _tj| jd�| _i | _d S )N)� sock_state_cb)r �current�io_loop�pycares�Channel�_sock_state_cb�channel�fds)�self� r �T/usr/local/CyberPanel/lib/python3.10/site-packages/tornado/platform/caresresolver.py� initialize$ s zCaresResolver.initialize�fd�readable�writablec C s~ |rt jnd|r t jndB }|s | j�|� | j|= d S || jv r/| j�||� || j|< d S | j�|| j|� || j|< d S )Nr ) r �READ�WRITEr �remove_handlerr �update_handler� add_handler�_handle_events)r r r r �stater r r r ) s z CaresResolver._sock_state_cb�eventsc C s: t j}t j}|tj@ r |}|tj@ r|}| j�||� d S �N)r �ARES_SOCKET_BADr r r r � process_fd)r r r$ �read_fd�write_fdr r r r" 5 s z CaresResolver._handle_eventsr �host�port�familyz*Generator[Any, Any, List[Tuple[int, Any]]]c # s� � t |�r |g}n&t� � | j�||� fdd�� � V \}}|r,td|tj�|�|f ��|j}g }|D ]3}d|v r=t j } n d|v rEt j } nt j } |t j krY|| krYtd|| f ��|� t�t| �||ff� q3|S )Nc s � � | |f�S r% )� set_result)�result�error��futr r �<lambda>H s z'CaresResolver.resolve.<locals>.<lambda>z/C-Ares returned error %s: %s while resolving %s�.�:z%Requested socket family %d but got %d)r r r � gethostbyname�IOErrorr �errno�strerror� addresses�socket�AF_INET�AF_INET6� AF_UNSPEC�append�typing�cast�int) r r* r+ r, r9 r. r/ �addrinfo�address�address_familyr r0 r �resolve> s8 �� �� � zCaresResolver.resolve)r N)r ) �__name__� __module__� __qualname__�__doc__r rA �boolr r" r � coroutine�strrE r r r r r s �����r )r r: �tornado.concurrentr �tornador �tornado.ioloopr �tornado.netutilr r r? � TYPE_CHECKINGr r r r r r r r r r �<module> s
