Release-Handler

Functionality

The release-handler handles release specific tasks of a repository. It runs as a postsubmit job in prow and identifies release activities by checking commited changes of a configurable VERSION file. The VERSION file must include a semver compatible version in its first line.

Currently, it identifies four cases:

• newRelease: when the version increases from a dev to a final version like v1.75.0-dev -> v1.75.0.
• nextDevCycle: when the version increases from a final to a higher dev version like v1.75.0 -> v1.75.1-dev
• prepareNewPatchVersion: when the version increases from one dev version to another with a higher patch version like v1.75.0-dev -> v1.75.1-dev
• prepareNewMajorMinorVersion: when the version increases from one dev version to another with a higher major or minor version like v1.75.0-dev -> v1.76.0-dev

When it identifies the prepareNewMajorMinorVersion case it creates a new release branch using a configurable pattern at the previous commit. The development could continue working on the main branch while the release verification activities are using the release branch. An example, when the version of the main branch increases from v1.75.0-dev to v1.76.0-dev release-handler creates a release branch for v1.75.
