PyDAS

Python rewrite of TAP's DAS. Functionally the same as DAS from 2016-03-20 (version 0.5.8).

It has full test coverage and some useful integration tests. It doesn't use Kafka, because it doesn't need to.

Deployment

• ./build_for_cf.sh
• cf push

Testing

• Install Docker
• Preparing a virtual environment, running the tests and quality check: tox
• Running just the tests without quality checks (from virtualenv): py.test tests/

Other development activities

• Activating virtualenv created by Tox: source .tox/py34/bin/activate
• Bumping the version: (while in virtualenv) bumpversion --alow-dirty patch
• Running the application: (you need to configure addresses in the script first) ./run_app.sh

Dependency management

Due to shenanigans with offline deployments the requirements need to go into two files:

• Add dependencies that need to compiled on the target platform and their dependencies requirements-native.txt.
• Pure Python dependencies should go to requirements-normal.txt.
• Running ./build_for_cf.sh will generate requirements.txt that can be used to deploy the app.
