I tried to discuss this topic in the past wrt AcceptedPreviousRelease, and
I didn't receive many responses from relevant people. From what I did
receive, I created this description (part of the official SOP, so it should
be "in production"):
https://fedoraproject.org/wiki/QA:SOP_blocker_bug_process#Tracking_AcceptedPreviousRelease_blocker_bugs

It might seem that this only discusses when to close
AcceptedPreviousRelease bugs. However, having all blocker bugs closed is a
prerequisite to voting "Go". So this is effectively a policy of how to
handle AcceptedPreviousRelease blockers state during Go/NoGo. The key
sentence describing the required state is:

"Only when it is guaranteed that MirrorManager refers only to the push
containing the fixed package or newer pushes, we should mark this bug
as *CLOSED
ERRATA*. "

And track-previous-release-blocker.py script implements that (it's quite
tedious to check that manually). I guess we could use the same approach
(and the same script) even for Accepted0Day. I'm not exactly sure how
'updates' repo is handled before Go, whether some people with older repos
can get older metadata not containing the required fix. If it is guaranteed
that 'updates' repo on release day is always up-to-day for all users (i.e.
it's the very push to that repo, no older metadata references are in
repomd.xml), it's even easier to check the state - just make sure the fix
is in updates-pending tag and we're good to go.

I wonder if we should provide a recommendation here - whether to target the
next milestone, or the equivalent milestone by default. Otherwise we spend
time discussing this each time (as we did during F26 cycle).

I think the more correct approach is to target the equivalent milestone.
But it also has higher demands on our team - we can't simply rely on the
dev team remembering this very important bug, otherwise we might find
ourselves at the very same situation for FN+1 Final milestone, just because
the dev team forgot about it. So we need to remind them and ask for status
regularly. There is more area for error when targeting the next milestone
(even if we found out

Thanks Adam for putting this together. I am definitely+1 to extend the
Blocker bug process with your proposal.

And there is one more topic related to this: how we should deal with
0day bugs found at the last moment before release ? Should not we have
a statement for Accepted0Day and AcceptedPreviousRelease blockers
saying that such bugs need to be verified and have enough karma before
relevant Go/No-Go meeting ? My question is base on the experience we
made during F26 release cycle, when we stopped already running
mirroring of a release as we realized the 0day fix will not be ready
at the release day. Having such a statement (and follow it) might save
the effort especially RelEng is putting into the release activities
after Go/No-Go meeting.

Jan

So there was some great feedback on the first version of this proposal;
here's the second draft, with all the suggestions considered and
applied. Note, given the misunderstanding between Kamil and Matt, I
added a little paragraph to specifically clarify that the list of
factors to consider really is just a list of things to *consider*, not
a checklist of criteria that we apply unthinkingly.

As I explained in the first mail, the proposal is to add a section to
https://fedoraproject.org/wiki/QA:SOP_blocker_bug_process , called
"Exceptional cases", as a sub-section of the 'Reviewing blocker bugs'
section. Here is the revised proposal for how the new section should
read:

##

=== Exceptional cases ===

Generally speaking, any bug that is agreed to be a violation of the
[[Fedora Release Criteria|release criteria]] should be accepted as a
blocker bug for the next relevant milestone release.

However, as explained in the [[Fedora_Release_Life_Cycle|Fedora life
cycle page]] and the
[[Fedora_Release_Criteria#Release_Constraints|release criteria]], we
consider Fedora's release process not to be strictly based on time
''or'' strictly based on quality, but to take both into consideration.
This can mean that, in some exceptional circumstances, we may agree
that a bug constitutes a sufficient violation of the release criteria
that it would ordinarily be accepted as a blocker bug for the next
milestone release, but in fact accept it as a blocker bug for a later
milestone release.

There are currently two established circumstances in which this may
occur.

Firstly, it may occur if it is agreed to be very unlikely that the bug
can be fixed within a reasonable time frame for the release to
be made.

Secondly, it may occur if the bug is discovered and/or proposed as a
blocker very late in the release validation process. Sometimes, a
relatively less important blocker bug (such as a non-vital default
installed application on a release-blocking medium failing to run, for
instance) may only be found very near the end of the release validation
process, too late for it to be reasonably possible to fix it without
delaying the release. Again, we may make the determination that in such
a case it is preferable to go ahead with the release rather than delay
it to fix such a late-discovered bug.

All such cases must be evaluated and discussed by the usual parties
(usually at a blocker bug review meeting) and all relevant factors must
be taken into account, much like the discussion of a bug that is a
'conditional' violation of the release criteria. At least the following
will almost always be relevant:

* The severity and likely prevalence of the bug
* Whether the bug could, or should, have been discovered and/or
proposed as a blocker earlier
* Whether the bug affects the existing stable releases (if it does,
there is generally less benefit to be had by delaying the new release)
* How long the release in question has already been delayed
* Whether delaying the release may give us an opportunity to carry out
other desirable work
* The possible effects of the expected delay (to Fedora itself, and
also to other things influenced by Fedora's schedules, including
downstream projects)

Note that these factors should be carefully and intelligently
considered on a case-by-case basis. This isn't a checklist; we cannot
just say "oh, that bug existed in the previous release, therefore it's
not a blocker, done". It's just a list of some of the factors we
typically ''consider'' in making this determination.

It is expected that in almost all 'exceptional' cases, the bug will be
accepted as a blocker either for the very next milestone release, or
for the equivalent milestone for the next release (e.g. if this
'exceptional' provision is agreed to apply to a bug that otherwise
would have blocked {{FedoraVersion|long|next}} Final, it should be
accepted as a blocker either for {{FedoraVersion|long|next2}} Alpha or
{{FedoraVersion|long|next2}} Final).

I'd argue that it does help - the bug gets fixed. The cost is maybe
delaying the release (if the bug is accepted as a blocker way ahead of the
milestone), or surely delaying the release (if the bug is accepted as a
blocker close to the milestone). The alternative is rejecting the blocker
right off the bat, which means the bug maybe gets fixed.

However, I think I misread your comment. I believed you're proposing we
reject bugs existing in stable releases as blockers at any point of the
development cycle. But you seem to have suggested we do this only if
they're discovered very shortly before the milestone deadline. Is that
correct? If so, I'm sorry for the confusion. In this case, I don't really
have a problem with this - it's the same approach as for any other bug
discovered a few hours before release. The impact is taken into
consideration, the difficulty of the fix is taken into consideration, and
also whether it already affects stable releases is taken into consideration
(why not, sure). If the bug is not critical, it's either pushed to the next
milestone, or pushed to the next release. That makes sense to me. If this
is the way it's formulated, I don't have a problem with it.

I think they're *clearly* different when it comes to delaying the
release. If a bug is not currently affecting anyone, delaying stops it
from becoming a user problem. If a bug is already a user problem,
delaying doesn't help those people — and just hurts everyone else who
would benefit from the release.

Prioritized Bugs is one avenue. I'm open to other suggestions. I think
in general packagers and maintainers *do* care about the kinds of bugs
that are likely to be in this situation.

And I agree with you, perhaps with one small exception. It depends on your
definition of "help", but the delay *is* sometimes effective in a sense
that without the delay (and the force function), the fix would not appear
fast (in stable updates shortly after release) or even at all. It is not a
good way to approach things, but I don't see many other options.
Developers' time is limited and blocker bugs do set project priorities. I
agree that it should definitely be used very conservatively.

But all of that above is a separate problem. What I'd like to understand is
why you think existing bugs should be treated differently from new bugs.
What is the rationale? And if you want to treat them differently, then how?
Because if we accept new problem A as a blocker, but waive problem B
because it has already existed for some time, even though they have
completely equal impact on users, then without any other means to push for
B resolution during the lifetime of the fedora release, it's very likely
that the problem will not get fixed. Do you see PrioritizedBugs as an
efficient way to help this? Or something else?

We should definitely fix these things. I just think that delaying the
release is a very big hammer -- in a case where maybe a hammer isn't
even called for. Delaying the release means that users are denied all
sorts of other improvements, and developers can't get their stuff in
the hands of users. The release delay itself doesn't _help_ the fix in
any way. We're just using it as a forcing function, and I think that
causes more problems than it actually solves.

I'm not in favor of this one. Too many important bugs have been waived in
the past (even those easily fixable) just because "it's not a new bug". I
don't see why it should matter. Sure, we can use the existing data to
better estimate the impact (how often people complain about this, bug
duplicates, etc). But that's just better input data. It should not affect
the decision process. Or is the thinking process something like "users are
already used to suffer from this bug, and perhaps can even work around it,
so we don't need to try that hard to fix it"? I don't agree to that.

For "could, or should, have been discovered earlier", there's also
"raised as a blocker earlier". There were a couple this time around
that actually had bugs filed but we didn't prioritize them until the
last minute.

Another consideration that might be relevant: is this a *new* issue or
something that also affects the current release (either as released or
with updates)? If something is a clear-cut blocker criterion violation
but isn't a regression *and* we're running late, using further release
delay as a forcing function feels like cutting off our nose to spite
our face.

Good point, thanks.

Indeed, you're exactly correct. Thank you.
