Development

Testing and Linting

This project uses Python unittest framework for unit tests, and pylint for lint checking.

python setup.py test

pylint --rcfile=./pylintrc ./efopen

Versions

This project uses Versioneer to manage the release versions, based on Git tags on the code repository.

Versions for Git working copies are generated on the fly based on the commit status of the working copy, and will change automatically as modifications are made and committed to the repository. For released packages, versions are frozen during packaging, and reflect the state of the working copy at the time the package was built.

Generated package versions follow the PEP440 spec, and will be of the form:

TAG[+DISTANCE.gSHORTHASH[.dirty]]

Where: TAG - the most recent Git tag string (written by the user when the Git tag was created) DISTANCE - the number of commits between the current commit and the given TAG. If this git commit is the tagged commit, this value will be omitted. SHORTHASH - the short Git ref hash, specifying the specific Git ref of the current commit. If this git commit is the tagged commit, this value will be omitted. ".dirty" - will be appended if the working copy has uncommitted changes to tracked files (but importantly, un-tracked files will not affect this flag).

Creating a new Release

To cut a new package release (for example, for a version 1.2.3):

• Git tag the target Git commit:

git tag -a 1.2.3 -m "Some reasonable tag message"

• Push the code and tag:

git push && git push --tags

The Jenkins CI pipeline will then recognize the new tag, build it, and publish it to PyPI. To be sure, watch the Jenkins pipeline progress and ensure that the new package tag is published to PyPI.

DO NOT delete a tag and retag the same tag on a different commit. This will not result in a replacement in PyPI, it will just make you sad.
