主题: [edk2-rfc] [RFC V3] Create supported branch from edk2-stable* tag
(Required to address critical bug BZ3111)

Hello,



The following bug has been fixed on edk2/master



https://bugzilla.tianocore.org/show_bug.cgi?id=3111

https://github.com/tianocore/edk2/pull/1226



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.



Thank you,



Mike
