Releases

Release Versions

Please note the following convention for release versions:

X.Y.Z: where:

  • X is an organizational release that signifies the completion of a core set of functionality
  • Y is a major version release that may include incompatible API changes and/or other breaking changes
  • Z is a minor version that includes bugfixes and backwards compatible improvements

Continuous Integration

CircleCI manages releases and release assets.

Whenever CircleCI passes on the master branch of cumulus-message-adapter and message_adapter/version.py has been updated with a version that doesn't match an existing tag, CircleCI will:

  • Create a new tag with tag_name of the string in message_adapter/version.py
  • Create a new release using the new tag, with a name equal to tag_name (equal to version).
  • Build a cumulus-message-adapter.zip file and attach it as a release asset to the newly created release. The zip file is created using the Makefile in the root of this repository.

These steps are fully detailed in the .circleci/config.yml file.

Development

Dependency Installation

pip install -r requirements-dev.txt
pip install -r requirements.txt

Running Tests

Running tests requires localstack.

Tests only require localstack running S3, which can be initiated with the following command:

SERVICES=s3 localstack start

And then you can check tests pass with the following nosetests command:

CUMULUS_ENV=testing nosetests -v -s

Linting

pylint message_adapter

Contributing

If changes are made to the codebase, you can create the cumulus-message-adapter zip archive for testing libraries that require it:

make clean
make cumulus-message-adapter.zip

Then you can run some integration tests:

./examples/example-node-message-adapter-lib.js

Troubleshooting

  • Error: "DistutilsOptionError: must supply either home or prefix/exec-prefix — not both" when running make cumulus-message-adapter.zip
