Skara Workflow for Update releases

[Langer, Christoph]

Hi Erik, Robin,

now that project Skara has hit mainline OpenJDK for quite a while, I’m starting to think more closely about how the workflow for backports and update releases will be.

I have lately recognized some activity in the Skara project to add functionality for the backport scenario flying by. I also understand that Yan and the folks maintaining 13u started using Skara already. I have a few questions however.

1. About the workflow for backports: I have seen that you’ve added the option “git pr create --backport REV”. So I take that this would be the canonical way to do a backport from an upstream change. Is there also support for cherry-picking changes from upstream via pure git and creating a PR from the backport, such that the Skara bots will recognize that the patch proposed is a backport?

2. What’s the workflow for merging between repositories? E.g. in 11u, we have 2 repos, one is jdk11u, the other is jdk11u-dev. We’re currently merging those repos once in a while in either direction. How is this supported by Skara? I guess I can add both remotes to my local repository and then merge branches and create PRs. However, what’ll happen then? Will the skara bots accept merging these branches (without squashing). What kind of checking will be in place? Can you please shed some light on how you imagine that process.

I’m asking because I’d like to see Skara being used consistently, also in JDK 11 Updates and I want to understand how far we’re away from that. ��

Thank you and best regards
Christoph
