This is a non-blocking and non-threaded resolver. It is recommended only when threads cannot be used, since it has limitations compared to the standard ``getaddrinfo``-based `~tornado.netutil.Resolver` and `~tornado.netutil.DefaultExecutorResolver`. Specifically, it returns at most one result, and arguments other than ``host`` and ``family`` are ignored. It may fail to resolve when ``family`` is not ``socket.AF_UNSPEC``. Requires Twisted 12.1 or newer. .. 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 jj�� | _t jj�d�}t jjj | jd�}t jj jd| jd�}t jj � |||g�| _ d S )Nz /etc/hosts)�reactorz/etc/resolv.conf)�twisted�internet�asyncioreactor�AsyncioSelectorReactorr �names�hostsr �cache� CacheResolver�client�resolve� ResolverChain�resolver)�self� host_resolver�cache_resolver� real_resolver� r! �N/usr/local/CyberPanel/lib/python3.10/site-packages/tornado/platform/twisted.py� initialize= s � �zTwistedResolver.initializer �host�port�familyz*Generator[Any, Any, List[Tuple[int, Any]]]c c s � t jj�|�r|}tj}nZt jj�|�r|}tj}nM| j� t |��}t � }|� |j � |V }t|tj�rOz|�� W n, t jjjyN } zt|��d }~ww t jj�|�rZtj}nt jj�|�retj}ntj}|tjkry||krytd||f ��t�t|�||ffg} | S )Nz%Requested socket family %d but got %d)r r �abstract� isIPAddress�socket�AF_INET� isIPv6Address�AF_INET6r � getHostByNamer r �addBoth� set_result� isinstancer �Failure�raiseExceptionr �error� DomainError�IOError� AF_UNSPEC� Exception�typing�cast�int) r r$ r% r& �resolved�resolved_family�deferred�fut�e�resultr! r! r" r K s: � �� �zTwistedResolver.resolve�r N)r ) �__name__� __module__� __qualname__�__doc__r# r � coroutine�strr: r r! r! r! r" r ' s �����r r c C s ddl m} | � dS )a� Install ``AsyncioSelectorReactor`` as the default Twisted reactor. .. deprecated:: 5.1 This function is provided for backwards compatibility; code that does not require compatibility with older versions of Tornado should use ``twisted.internet.asyncioreactor.install()`` directly. .. versionchanged:: 6.0.3 In Tornado 5.x and before, this function installed a reactor based on the Tornado ``IOLoop``.
