pycares: Python interface for c-ares

pycares is a Python module which provides an interface to c-ares.
c-ares <https://c-ares.org>_ is a C library that performs
DNS requests and name resolutions asynchronously.

Documentation

http://readthedocs.org/docs/pycares/

Bundled c-ares

pycares currently bundles c-ares as a submodule for ease of building. Using the system
provided c-ares is possible if the PYCARES_USE_SYSTEM_LIB environment variable is
set to 1 when building.

NOTE: Versions prior to 4.0.0 used to embed a modified c-ares with extended TTL support.
That is no longer the case and as a result only A and AAAA records will have TTL information.
Follow this PR in uppstream c-ares, looks like TTLs will be added: https://github.com/c-ares/c-ares/pull/393

Installation

GNU/Linux, macOS, Windows, others:

::

pip install pycares

FreeBSD:

::

cd /usr/ports/dns/py-pycares && make install

IDNA 2008 support
^^^^^^^^^^^^^^^^^

If the idna package is installed, pycares will support IDNA 2008 encoding otherwise the builtin idna codec will be used,
which provides IDNA 2003 support.

You can force this at installation time as follows:

::

pip install pycares[idna]

Running the test suite

From the top level directory, run: python -m unittest -v

NOTE: Running the tests requires internet access and are somewhat environment sensitive because real DNS quesries
are made, there is no mocking. If you observe a failure that the CI cannot reproduce, please try to setup an
environment as close as the current CI.

Using it from the cli, a la dig

This module can be used directly from the command line in a similar fashion to dig (limited, of course):

::

$ python -m pycares google.com
