Contributing to libEnsemble
Contributions may be made via a GitHub pull request to
libEnsemble uses the Gitflow model. Contributors should branch from, and make pull requests to, the develop branch. The master branch is used only for releases. Pull requests may be made from a fork, for those without repository write access.
Code should pass flake8 tests, allowing for the exceptions given in the flake8 file in the project directory.
Issues can be raised at
Issues may include reporting bugs or suggested features. Administrators will add issues, as appropriate, to the project board at
By convention, user branch names should have a <type>/<name> format, where example types are feature, bugfix, testing, docs, and experimental. Administrators may take a hotfix branch from the master, which will be merged into master (as a patch) and develop. Administrators may also take a release branch off develop and then merge this branch into master and develop for a release. Most branches should relate to an issue or feature.
When a branch closes a related issue, the pull request message should include the phrase “Closes #N,” where N is the issue number. This will automatically close out the issues when they are pulled into the default branch (currently master).
