musicbrainz-data

Data access layer for the NES version of the MusicBrainz database.

Installing

musicbrainz-data is packaged using Cabal, and requires GHC 7.4 (or higher). We recommend installing the 2012.2.0.0 version of the Haskell Platform, as this provides a lot of dependencies this project uses; however, with an up to cabal-install and the aforementioned GHC version satisfied you should also be able to build this project.

You also need access to a postgresql database server with the cube and uuid-ossp extensions, on Ubuntu 12.04 and 12.10 these extensions are in the postgresql-contrib-9.1 package.

Once you have those requirements, simply run:

cabal install

Working on musicbrainz-data.

Dependencies

To install just the dependencies needed to run musicbrainz-data, run:

cabal install --only-dependencies.

If you plan to run tests, you will need to run:

cabal install --enable-tests --only-dependencies.

Building

To build, simply run cabal build.

Running tests

To run tests you first need to set up the test database, run the following commands (obviously the createuser isn't needed if you already have a musicbrainz user, and the dropdb isn't needed if you don't have an existing musicbrainz_nes database):

createuser -U postgres musicbrainz --no-createdb --no-superuser --no-createrole;
dropdb     -U postgres musicbrainz_nes
createdb   -U postgres musicbrainz_nes --owner=musicbrainz
psql       -U postgres musicbrainz_nes

That last command will start the postgresql prompt, on that prompt run the following commands:

CREATE EXTENSION "uuid-ossp"
CREATE EXTENSION cube
\i test/data/test-schema.sql
\q

Your database is now ready to run the tests.

We use Cabal to run tests. To build tests while you develop, enable test building when you configure musicbrainz-data:

cabal configure --enable-tests

Every time you run cabal build you will also build tests. You can run tests by running:

cabal test

Check the output of cabal test --help for various things that can also be done while you run tests.

Something went wrong with that request. Please try again.
