This is typically slower than the default threaded resolver (unless there's a cache hit, in which case it can be much faster). It is usually much faster than the c-ares resolver. It tends to scale well as more concurrent resolutions are attempted. Under Python 2, if the ``idna`` package is installed, this resolver can resolve Unicode host names that the system resolver cannot. .. note:: This **does not** use dnspython's default resolver object, or share any classes with ``import dns``. A separate copy of the objects is imported to be able to function in a non monkey-patched process. The documentation for the resolver object still applies. The resolver that we use is available as the :attr:`resolver` attribute of this object (typically ``gevent.get_hub().resolver.resolver``). .. caution:: Many of the same caveats about DNS results apply here as are documented for :class:`gevent.resolver.ares.Resolver`. In addition, the handling of symbolic scope IDs in IPv6 addresses passed to ``getaddrinfo`` exhibits some differences. On PyPy, ``getnameinfo`` can produce results when CPython raises ``socket.error``, and gevent's DNSPython resolver also raises ``socket.error``. .. caution:: This resolver is experimental. It may be removed or modified in the future. As always, feedback is welcome. .. versionadded:: 1.3a2 .. versionchanged:: 20.5.0 The errors raised are now much more consistent with those raised by the standard library resolvers. Handling of localhost and broadcast names is now more consistent. .. _dnspython: http://www.dnspython.org NcCsZtjdurt}t_tjrtj|jjdd<tjrtj|j_t tjts'Jtj|_dSr') r _resolverrrresolver_nameserversr nameserversresolver_timeoutlifetimero)rZhubrr r r%r\s    zResolver.__init__cCs|jjS)a The dnspython resolver object we use. This object has several useful attributes that can be used to adjust the behaviour of the DNS system: * ``cache`` is a :class:`dns.resolver.LRUCache`. Its maximum size can be configured by calling :meth:`resolver.cache.set_max_size` * ``nameservers`` controls which nameservers to talk to * ``lifetime`` configures a timeout for each individual query. )rrrr r r%rs zResolver.resolvercCr?r'r rr r r%closeszResolver.closec Cst|tst|tr|d}|jj|}|jj}t|} z | |t j j |}Wn5t j jt j jt j jfy=Y|StyFY|Sty_}z|dusVt|trZt|d}~ww|dd|jD|dj}q)Nrcss|]}t|jVqdSr')rptarget).0rrr r r% sz'Resolver._getaliases..r)rorprrrrrrrr~rr.rfrrUNXDOMAIN NoNameserversdTimeoutr,int TypeErrorextendrVr)rZrrHru net_resolverr3ansexr r r% _getaliasess0     zResolver._getaliasesc Cst|ts ||j}|dkrd}|tkrHz t||||||WStyGz t||t|||WYStyFt||t|||YYSwwz t||||||WStyt}z|j dt kro||j vrot |j f|_ t |_d}~ww)Nzff02::1de:c0:face:8Dzff02::1de:c0:face:8dr)rorprHOSTNAME_ENCODINGr rOrr r argsr _KNOWN_ADDR_FAMILIESr EAI_FAMILY_MSGerrno)rZ host_bytesportrHrIrJrKrr r r%rOs.      zResolver._getaddrinfocCs8zt||WSty|st|tYSYdSwr')r _getnameinforr)rZ address_bytesrsockaddrrKr r r%rs zResolver._getnameinfoc Cs@zt|WSty}z |jdtkrtddd}~ww)Nrrz Unknown host)r_gethostbyaddrrrr r)rZip_address_bytesrr r r%rs  zResolver._gethostbyaddrr')r]r^r_rr\propertyrrrrOrrrfixup_gaierror getnameinfo gethostbyaddrgethostbyname_ex getaddrinfor r r r%rPs 1 +   )- __future__rrrrrX_socketrrrrr r r r r rBgevent.resolverrgevent.resolver._hostsfilergevent.builtinsrg_importgevent._compatrrgevent._configr__all__r=rrTimeoutrrOgetattrrAnswerrPobjectr`rrrr r r r%sJ<                7  N)
