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. returnNctjj|_tjjd}tjj |j}tjj d|j}tjj |||g|_ dS)Nz /etc/hosts)reactorz/etc/resolv.conf)twistedinternetasyncioreactorAsyncioSelectorReactorrnameshostsr cache CacheResolverclientresolve ResolverChainresolver)self host_resolvercache_resolver real_resolvers 8lib/python3.11/site-packages/tornado/platform/twisted.py initializezTwistedResolver.initialize=s'6MMOO  +44\BB  ,::4<:PP ,55  6   -;; NM :   rhostportfamilyz*Generator[Any, Any, List[Tuple[int, Any]]]c#Ktjj|r|}tj}nUtjj|r|}tj}n!|j t|}t}| |j |V}t|tjrF |n#tjjj$r}t+|d}~wwxYwtjj|r tj}n=tjj|r tj}n tj}|tjkr||krt/d||fzt1jt4|||ffg} | S)Nz%Requested socket family %d but got %d)rrabstract isIPAddresssocketAF_INET isIPv6AddressAF_INET6r getHostByNamerraddBoth set_result isinstancerFailureraiseExceptionrerror DomainErrorIOError AF_UNSPEC Exceptiontypingcastint) rr&r'r(resolvedresolved_familydeferredfuteresults r#rzTwistedResolver.resolveKs   $ 0 0 6 6 3H$nOO   & 4 4T : : 3H$oOO}224::>>H((C   S^ , , , yyH(GO44 3%++----}*6%%%!!**$%!*66x@@ 3"(.!*88BB 3"(/"("2 V% % %&O*C*C76?:SS ;sO44x6FGH sC..DDDrN)r) __name__ __module__ __qualname____doc__r$r coroutinestrr=rr%r#rr's|*      ]23   " ,/  5   ]   r%rrc&ddlm}|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.
