Rohit,
I read your proposal, but maybe I mistook your idea:
"- After code freeze is declared and release branch is cut out,
contributors work on fixing bugs and other changes (such as documentation,
build/packaging fixes etc.) first on the release branch (and not master).
This is not to restrict anyone working on master, features and other
changes can keep landing on master as well. This is to encourage
contributors to give more attention to release branches by at least fixing
bugs on release branches first and not our current way where we fix it on
master and ask RMs to cherry pick it to release branch".
What do you mean by this? So after release branch is cut, and contributors
need to fix a bug (as we experienced so many times in past releases), what
should they do? Based on your sentence above, I understood that they can
just directly commit to release branch instead of currently checking into
some forward branch and RM then cherry-pick it up to release branch to
control quality. What is your new proposed approach then? Please clarify.
Thanks
-min
