主题: [RFC V2] Create supported branch from edk2-stable* tag (Required to
address critical bug BZ3111)
The following bug has been fixed on edk2/master
This bug is also considered a critical bug against edk2-stable202011. The
of the Variable Lock Protocol was changed in a non-backwards compatible
edk2-stable202011 and this is impacting some downstream platforms. The
2 commits on edk2/master restore the original behavior of the Variable Lock
[Liming] This one is for unit test. It is not critical fix. I don't think it is required.
The request here is to create a supported branch from edk2-stable202011 tag
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
need to be addressed:
1) Supported branch naming convention.
Here is my suggestion on the live period of the stable tag branch.
The stable tag branch will be created only when the critical issue is found in this stable tag. By default, no stable tag branch is created.
Now, the quarterly stable tag will be created every three months. So, this branch will exist for at most three months.
Once next stable tag is created, new stable tag will be used. Previous stable tag branch will not be maintained.
That means only latest stable tag branch will be maintained if it is created.
2) CI requirements for supported branches.
Proposal: Update .azurepipelines yml files to also trigger on stable/*
and update GitHub settings so stable/* branches are protected
The patch has been verified in master. CI test may not be necessary.
3) Release requirements for supported branches.
Proposal: If there are a significant number of critical fixes applied to
a stable/edk2-stable* branch, then a request for a release can be made
would trigger focused testing of the supported branch and creation of a
release. If all testing passes, then a tag is created on the
branch and a release is created on GitHub that summarizes the set of
fixes and the testing performed.
Example : edk2-stable201111.01
It is OK to create new stable tag per the request. The platform can use stable branch.
Besides, there are few new issues. I have cancelled the bug triage meeting.
Please let me know if you have any feedback or comments on this proposal.
is to close on this topic this week.
