Very nice. This could make the rollout process much faster and less stressful. I noticed one point missing from this summary: the use of a full weekend staging update to gauge the rollout downtime, and presumably to forecast the clean application of all DB patches from the last week. This update also has the unfortunate potential to block all QA for patches landed after Monday. I do not see the database update steps mentioned in your summary. Are they something we should think about? Can we work them into, or out of, a shorter release process? To better visualize what happens today, here is a rough release timeline: Thursday: lock down devel landings (to release-critical) lock down db-devel landings (to release-critical) while unqaed: qa Saturday: * wait for a full staging update * work to get the staging database to update cleanly Monday: rc-landings while unqaed: qa release-critical work Wednesday: choose the rev of db-devel ...
