Ingestion, validation and authoring tool for the Firefox Directory and Enhanced Tiles project

• python
• pip
• virtualenv
• postgres
• libmagic

Get your virtualenv environment setup.

• ./setup-project.sh
• source ./splice-env/bin/activate

Create databases in postgres.

psql postgres
create database mozsplice;
create database mozsplice_campaigns;

Next get your postgresql database setup

• manage.py db upgrade

To be able to fully use Splice, you will need to use custom S3 credentials, you might want to use your own database settings, etc.

The boto configuration file looks like this:

[Credentials]
aws_access_key_id = SOME_ACCESS_KEY
aws_secret_access_key = SOME_SECRET_KEY

[Boto]
debug = 0

Place it anywhere by using the BOTO_CONFIG environment variable, put it in a global location, /etc/boto.cfg, or put it in a user-specific location, $HOME/.boto.

More on boto config at the documentation page.

As an alternative to the boto config, you can set AWS environment variables and boto will automatically pick up the credentials.

i.e. you can set your credentials to the respective environment variables:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• AWS_SECURITY_TOKEN (optional)

Finally, you can setup your AWS credentials via an overriden splice config file. See below.

To override the default configuration in splice, you will want to create a custom configuration file. Here's an example file:

from splice.default_settings import DefaultConfig

class SpliceConfig(DefaultConfig):
    ENVIRONMENT = 'dev'
    DEBUG = True

    # overriding the default DB config with creds
    SQLALCHEMY_DATABASE_URI = 'postgres://user:password@localhost/mozsplice'
    SQLALCHEMY_BINDS = {
        'stats': 'postgres://user:password@localhost/mozsplice_campaigns',
    }

    AWS = None # To let boto figure out its configuration
    """
    To tell boto what creds to use
    AWS = {
        "key": "development_key",
        "secret_key": "government_secret"
    }
    """

    S3 = {
        'bucket': 'moz-tiles-mybucket',
        'tile_index_key': 'tile_index_v3.json',
    }

    # do not use a CDN, instead, use S3 url for the above defined bucket
    CLOUDFRONT_BASE_URL = 'https://%s.s3.amazonaws.com' % S3['bucket']

A few things to note:

• The configuration file is a python module
• It subclasses the default config, and allows overriding the default
• For development, you want the CLOUDFRONT_BASE_URL parameter to be the S3 bucket probably
• You might want to use your own bucket
• AWS = None tells splice to let boto decide where to get credentials. Alternatively, you can configure it here.

You will want to place the configuration file somewhere in your PYTHON_PATH. The root of the splice repository will do. If you name this file splice_config.py, you can make splice use it with the command below:

$ SPLICE_SETTINGS=splice_config.SpliceConfig manage.py runserver_gunicorn

• manage.py
• manage.py data --help: link ingestion command line tools
• manage.py runserver_gunicorn: run a webserver listening on port 5000
• SPLICE_SETTINGS=my_config.MyConfig manage.py runserver_gunicorn: run a webserver listening on port 5000, using custom configuration

Create test database in postgres.

psql postgres
create database splice_test;

• fab test: run unit tests and code coverage tools
