I think we will probably always have this struggle around the time we cut a new release branch and then need to decide what changes on develop to also bring to the release branch. I'm okay with us not including the big cleanup in 1.15 since it is not something we plan on backporting to other support branches and if we had cut the 1.15 release branch right before this change, I don't think we would have approved it to be back ported to the 1.15 release branch.
I share Owen's concern that not including it might case extra work in resolving conflicts in every change to develop after it that we also want to include in 1.15. We will not know if this is true until we try cherry-picking those revisions. So I'm unsure what the best way of not including it is. I'm okay with us cutting the branch from the revision before the big commit and then working through the list of commits after it and deciding which need to be in the 1.15 release. ________________________________ From: Alexander Murmann <amurm...@vmware.com> Sent: Wednesday, January 26, 2022 7:21 AM To: dev@geode.apache.org <dev@geode.apache.org> Subject: Re: Proposal: Cut 1.15 release branch from SHA 8f7193c827ee3198ae374101221c02039c70a561 Owen, I really appreciate your point about the increased cost of backports by the branches diverging like this. I do wonder how high the cost will be in practice, given that AFAIK most of these changes limit themselves to a single line. ________________________________ From: Owen Nichols <onich...@vmware.com> Sent: Tuesday, January 25, 2022 20:18 To: dev@geode.apache.org <dev@geode.apache.org> Subject: Re: Proposal: Cut 1.15 release branch from SHA 8f7193c827ee3198ae374101221c02039c70a561 Even a small change can have subtle but important effects only discovered after a long time, so leaning on commit-size as a proxy for risk may only serve to create a false sense of security. Also to consider, having a large refactor on develop but not support/1.15 will increase backporting pain, as many cherry-picks will have merge conflicts that have to be manually "un-refactored".

I would like to propose that we cut the branch from last week's SHA 8f7193c827ee3198ae374101221c02039c70a561. The following commit is a very large refactor. Nothing obvious seems wrong with that change, but given that we frequently only discover very subtle, but important changes to Geode after a long time, I think that this would allow us to reduce some risk for 1.15 and its future users and give this large change some time to proof itself on the develop branch. I'd love to avoid that work entirely, but am concerned that we only might find out about problems a few weeks from now or worse, after we shipped. Another option might be to branch from head and revert the change on the release branch. I am uncertain which approach will proof less work.
