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

.. image:: https://badge.fury.io/py/aiodns.png
    :target: https://pypi.org/project/aiodns/

.. image:: https://github.com/saghul/aiodns/workflows/CI/badge.svg
    :target: https://github.com/saghul/aiodns/actions

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``
