pycares is a Python module which provides an interface to c-ares. c-ares is a C library that performs DNS requests and name resolutions asynchronously.

Bundled c-ares

pycares currently bundles c-ares and as of pycares 1.0.0 this is a strong requirement. Upstream c-ares is not willing to apply a patch adding TTL support. I did apply the patch to the bundled c-ares, but unfortunately it breaks the ABI, so attempting to use a system provided c-ares is not possible.

Building

Linux:

python setup.py install

Mac OSX:

(XCode needs to be installed)
export ARCHFLAGS="-arch x86_64"
python setup.py install

Microsoft Windows (with Visual Studio 2008, 2010, 2015 or the Windows SDK):

./build_inplace

Running the test suite

There are several ways of running the test ruite:

• Run the test with the current Python interpreter:

  From the toplevel directory, run: python tests/tests.py

• Use Tox to run the test suite in several virtualenvs with several interpreters

  From the toplevel directory, run: tox -e py27,py33,py34,py35 this will run the test suite on Python 2.7, 3.3, 3.4 and 3.5 (you'll need to have them installed beforehand)
