Credits

Code from http://pypi.python.org/pypi/rod.recipe.rabbitmq package has been used as a starting point.

A brief documentation

This recipe takes a number of options:

erlang-path

The path where to find the erlc command (default = find it in your path).

url

The URL to download the Riak source distribution.

prefix

Prefix path (default = <buildout directory>).

cookie

Optional string passed as cookie to the erl runtime (-setcookie)

Tests

We will define a buildout template used by the recipe:

>>> buildout_cfg = """
... [buildout]
... parts = riakbuild
... offline = true
...
... [riakbuild]
... recipe = biodec.recipe.riak:build
... url = http://s3.amazonaws.com/downloads.basho.com/riak/CURRENT/riak-1.2.0.tar.gz
...
... """

We’ll start by creating a buildout:

>>> import os.path
>>> write('buildout.cfg', buildout_cfg)

Running the buildout gives us:

>>> print system(buildout)
Installing riakbuild.
...
==> rel (compile)
==> riakbuild (compile)
Compiled src/etop_txt.erl
...

Re-run buildout:

>>> print system(buildout)
Updating riakbuild.
