晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

Simple DNS resolver for asyncio
===============================

aiodns provides a simple way for doing asynchronous DNS resolutions using `pycares <https://github.com/saghul/pycares>`_.


Example
=======

.. code:: python

    import asyncio
    import aiodns

    loop = asyncio.get_event_loop()
    resolver = aiodns.DNSResolver(loop=loop)

    async def query(name, query_type):
        return await resolver.query(name, query_type)

    coro = query('google.com', 'A')
    result = loop.run_until_complete(coro)


The following query types are supported: A, AAAA, ANY, CAA, CNAME, MX, NAPTR, NS, PTR, SOA, SRV, TXT.


API
===

The API is pretty simple, three functions are provided in the ``DNSResolver`` class:

* ``query(host, type)``: Do a DNS resolution of the given type for the given hostname. It returns an
  instance of ``asyncio.Future``. The actual result of the DNS query is taken directly from pycares.
  As of version 1.0.0 of aiodns (and pycares, for that matter) results are always namedtuple-like
  objects with different attributes. Please check the `documentation 
  <http://pycares.readthedocs.org/en/latest/channel.html#pycares.Channel.query>`_
  for the result fields.
* ``gethostbyname(host, socket_family)``: Do a DNS resolution for the given
  hostname and the desired type of address family (i.e. ``socket.AF_INET``).
  While ``query()`` always performs a request to a DNS server,
  ``gethostbyname()`` first looks into ``/etc/hosts`` and thus can resolve
  local hostnames (such as ``localhost``).  Please check `the documentation
  <http://pycares.readthedocs.io/en/latest/channel.html#pycares.Channel.gethostbyname>`_
  for the result fields. The actual result of the call is a ``asyncio.Future``.
* ``gethostbyaddr(name)``: Make a reverse lookup for an address.
* ``cancel()``: Cancel all pending DNS queries. All futures will get ``DNSError`` exception set, with
  ``ARES_ECANCELLED`` errno.


Running the test suite
======================

To run the test suite: ``python tests.py``
