The bots will automatically detect if the commit in a backport pull request is a clean backport. If it is then bots will add the label "clean" to the pull requests. Backport pull requests which commit is a clean backport can be integrated without reviewers (configurable per repository). This means that not all commit messages for backport commits will have a "Reviewed-by" line.
The Skara CLI tools features the tool git pr create for creating pull requests. The option
git pr create makes the title of pull request consist of "Backport" and the given hash, for example
git pr create --backport=5a526c1c5716f6d9a7fc94741bcdb2f424d342df creates a pull request with the title "Backport 5a526c1c5716f6d9a7fc94741bcdb2f424d342df". The value of
--backport does not have to be a full hash, it can be an abbreviated hash or a reference.
Backport Commit Command
The /backport commit command can be used to quickly create a backport pull request for a given commit. Just navigate to the comment in source code hosting provider's web UI and add a comment consisting of "/backport <repo>". If the commit does not apply clean on the target repository then a message will be shown for the files with conflicts.
