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. returnNcCs\tjj|_tjjd}tjjj |jd}tjj jd|jd}tjj |||g|_ dS)Nz /etc/hosts)reactorz/etc/resolv.conf)twistedinternetZasyncioreactorZAsyncioSelectorReactorrnameshostsr cacheZ CacheResolverclientresolveZ ResolverChainresolver)selfZ host_resolverZcache_resolverZ real_resolverrO/var/www/html/lang_env/lib/python3.10/site-packages/tornado/platform/twisted.py initialize=s zTwistedResolver.initializerhostportfamilyz*Generator[Any, Any, List[Tuple[int, Any]]]c cs tjj|r|}tj}nZtjj|r|}tj}nM|j t |}t }| |j |V}t|tjrOz|Wn,tjjjyN}zt|d}~wwtjj|rZtj}ntjj|retj}ntj}|tjkry||krytd||ftt|||ffg} | S)Nz%Requested socket family %d but got %d)rrZabstractZ isIPAddresssocketAF_INETZ isIPv6AddressAF_INET6rZ getHostByNamerrZaddBoth set_result isinstancerFailureraiseExceptionrerrorZ DomainErrorIOError AF_UNSPEC Exceptiontypingcastint) rrrrresolvedZresolved_familydeferredZfuteresultrrrrKs:    zTwistedResolver.resolverN)r) __name__ __module__ __qualname____doc__rr coroutinestrr-rrrrrr's rrcCsddlm}|dS)aInstall ``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``. When that reactor implementation was removed in Tornado 6.0.0, this function was removed as well.
