Once we've pulled the 19.08 release throttle

We need to be disciplined with respect to bugfix commits. Here are a few common-sense suggestions:

  • All bug fixes must be double-committed to the release throttle as well as to the master branch
    • Commit first to the release throttle, then "git cherry-pick" into master
    • Manual merges may be required, depending on the degree of divergence between throttle and master
  • All bug fixes need to have a Jira ticket
    • Please put Jira IDs into the commit messages.
    • Please use the same Jira ID for commits into the stable branch and master.
