There was a problem hiding this comment. We are hashing branch names for identifying preview deployments inside all of AWS. We also have to create the preview deployment domain using some kind of deterministic identifier based on the preview branch. Turned out we cannot just use branch names in preview domains because branch names have a far wider character set than domain names allow for. E.g. the domain |

There was a problem hiding this comment. We are marking almost all worker handlers in Kayron as always active. The alternative would be to wrap every worker handler in a proxy worker handler, but I thought this approach here is more explicit. |

This is ugly, but this enables us to reuse some information in one place, which we already fetched from the Github API in another place. E.g. the
previewworker handler resets the preview flag of the release artifact of any main release that defines preview releases for its entire repository. I don't know how to make this better at this point in time.
