[RFC V3] Create supported branch from edk2-stable* tag (Required to address critical bug BZ3111)
Michael D Kinney
The following bug has been fixed on edk2/master
This bug is also considered a critical bug against edk2-stable202011. The behavior
of the Variable Lock Protocol was changed in a non-backwards compatible manner in
edk2-stable202011 and this is impacting some downstream platforms. The following
2 commits on edk2/master restore the original behavior of the Variable Lock Protocol.
The request here is to create a supported branch from edk2-stable202011 tag and apply
these 2 commits as critical bug fixes on the supported branch.
Since we started using the edk2-stable* tag process, there has not been a request to create
a supported branch from one of those tags. As a result, there are a couple opens that
need to be addressed:
1) Supported branch naming convention.
Branch Proposal: stable/<YYYY><MM>
Branch Example: stable/202011
2) CI requirements for supported branches.
Proposal: Update .azurepipelines yml files to trigger on stable/* branches,
update .mergify configuration file to support merging of stable/* branches,
and update GitHub branch protection settings to protect stable/* branches.
3) A stable/* branch is only supported until the next edk2-stable tag release.
4) Release requirements for supported branches.
Proposal: If there are a significant number of critical fixes applied to
a stable/* branch, then a request for a release can be made that would
trigger focused testing of the supported branch and creation of a new
release. If all testing passes, then a tag is created on the stable/*
branch and a release is created on GitHub that summarizes the set of
critical fixes and the testing performed.
Tag Proposal: edk2-stable<YYYY><MM>.<XX>
Tag Example : edk2-stable202011.01
Please let me know if you have any feedback or comments on this proposal. The goal
is to close on this topic this week.
