Almost all of our old bugfix branches are in the list. Additionally, not properly retiring the bugfix branches leads to an ever-growing list of branches which makes it a lot more difficult, for contributors and operators alike, to tell which ones are currently supported.</div></div></blockquote><div><br></div><div>I'd like to see the errors. We update Zuul configuration manually for each bugfix branch, mapping appropriate branches for other projects (devstack, nova, etc). It's possible that we always overlook a few jobs, which causes Zuul to be upset (but quietly upset, so we don't notice).<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><br></div><div>I've put together a document describing the situation as it is now, and my proposal:</div><div><a href="https://etherpad.opendev.org/p/IronicBugfixBranchCleanup" target="_blank">https://etherpad.opendev.org/p/IronicBugfixBranchCleanup</a></div></div></blockquote><div><br></div><div>Going with the "I would like to retire" would cause us so much trouble that we'll have to urgently create a downstream mirror of them. Once we do this, using upstream bugfix branches at all will be questionable. Especially bugfix/19.0 (and corresponding IPA/inspector branches) is used in a very actively maintained release.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><br></div><div>Essentially, I think we need to:</div><div>- identify bugfix branches to cleanup (I've done this in the above etherpad, but some of the )</div><div>- clean them up (the next step)<br></div><div>- update Ironic policy to set a regular cadence for when to retire bugfix branches, and encode the process for doing so</div><div><br></div><div>This means there are two overall questions to answer in this email:</div><div>1) Mechanically, what's the process for doing this? I don't believe the existing release tooling will be useful for this, but I'm not 100% sure. I've pulled (in the above etherpad and a local spreadsheet) the last SHA for each branch; so we should be able to EOL these branches similarly to how we EOL stable branches; except manually instead of with tooling. Who is going to do this work? (I'd prefer releases team continue to hold the keys to do this; but I understand if you don't want to take on this manual work).</div></div></blockquote><div><br></div><div>EOL tags will be created by the release team, yes. I don't think we can get the keys without going "independent".<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><br></div><div>2) What's the pattern for Ironic to adopt regarding these branches? We just need to write down the expected lifecycle and enforce it -- so we prevent being this deep into "branch debt" in the future.</div></div></blockquote><div><br></div><div>With my vendor's (red) hat on, I'd prefer to have a dual approach: the newest branches are supported by the community (i.e. us all), the oldest - by vendors who need them (EOLed if nobody volunteers). I think you already have a list of branches that OCP uses? Feel free to point Riccardo, Iury or myself at any issues with them.</div><div><br></div><div>Dmitry<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><br></div><div><br></div><div>What do folks think?</div><div><br></div><div>- <br></div><div>Jay Faulkner<br></div></div>
