Looks like everyone is interested in having frequent releases - I don't see anyone disagreeing with that.

Regarding "If a patch makes the release branch unstable, we revert it" - what are the criteria? If we can't decide on the criteria on this thread (already pretty long) then lets get the release trains going. We can revisit the criteria for inclusion of bug fixes when that happens.

The release branch receives only bug fixes. Patch level releases (3rd
version number) are issued out of the release branch and introduce
only bug fixes and no new features.
Deciding whether a patch is applied to the release branch is based on
preserving stability (as Bill said). If a patch makes the release
branch unstable, we revert it.
New features are added to trunk where new major and minor releases will happen.
If we need a new feature out then we make a new minor release.
Doing frequent releases is the industry standard and will resolve
conflicts around what should go in a release branch.

Making a new release is currently painful *because* we wait so long in
between two releases. Let's fix that.

Proposed criteria:
 - it makes the tests fail. targets test-commit + test + e2e tests
 - a critical bug is reported in a short time frame (definition of
critical not needed as it is rare and can be decided on a case by case
basis)

That raises another question: what are the existing CI servers running
the tests?
 - the Apache CI runs test-commit and test (is it more stable now?)
and not e2e. It would be great if it did.
 - we have a Jenkins build at Twitter where we run test-commit and
test, we could not run e2e easily in our environment.
 - I understand there's a Yahoo/Hortonworks build (test-commit + test + e2e ???)

Whenever those builds fail we should open or reopen JIRAS and fix it.

The time it takes to run the full test suite makes it impractical to
run on a desktop/laptop.

For the release Pig-0.11.0 we need to get this list of JIRAs down to 0
and publish the jar.

HI Julien,

You are making most of the points that I did on this thread (CI for e2e, not burdening clean e2e prior to every commit for a release branch). The only point on which there is no clear agreement is the definition of a bug that can be included in a previously released branch. I am fine with a case by case inclusion. 

Hi Olga,

Are you fine with Julien's proposal as it stands - bugs that are included will be determined at the time of inclusion instead of doing it now.

I am ok with tests running nightly and reverting patches that cause failures. We used to have that. Does anybody know what happened? Is anybody volunteering to make it work again?

I would like to see specific criteria for what goes into the branch been published (rather than case-by-case). This way each team can decided if the criteria stringent enough of if they need to run a private branch.

Here's my criteria for inclusion in a release branch:
 - no new feature. Only bug fixes.
 - The criteria is more about stability than priority. The person/group
asking for it has a good reason for wanting it in the branch. If commiters
think the patch is reasonable and won't make the branch unstable then we
should check it in. If it breaks something anyway, we revert it.

For what it's worth we (at Twitter) maintain an internal branch where we
add patches we need and I would suggest anybody that wants to be able to
make emergency fixes to their own deployment to do the same. We do keep
that branch as close to apache as we can but it has a few patches that are
in trunk only and do not satisfy the no new feature criteria.

What does the PMC think ?

If everybody is using a private branch then

(1) We are not serving a significant part of our community
(2) There is no motivation to contribute those patches to branches (only to trunk).

Yahoo has been trying hard to work of the Apache branches but if we increase the scope of what is going into branches, we will go with private branch approach as well.

Wait. Ack. Do we want everyone to do this? This sounds like fragmentation. :(

Share the same concern as Russell here. Not great for the project for
everyone to go "private branch" approach.

I think we all agree here, let's not jump to conclusions.
Everything in this branch I am talking about is in Apache Pig. Everything
we do in Pig is contributed.
We have a branch for 0.11 where we keep merging the official 0.11 branch
plus a few patches (and it will stay small) that are only in Apache TRUNK.
The goal here is to help keeping the release branch stable by not adding
patches that are only useful to us.
Having this branch allows us to fix anything quickly and redeploy to
production. It is also what allows us to use the pig 0.11 branch in
production before it is even released.
This definitely benefits the community and helps making 0.11 stable.
This is a very reasonable way to keep using a recent version of Pig in
production.

Olga: My goal is to decrease the scope of what is going in the release
branch and to make sure we add only bug fixes that are not making it
unstable. I also think having a short definition of this helps which is why
I have been chiming in.
Let us know how you want to decrease the scope. I'm just trying to simplify
here.

Hi Julien,

I understand what you are trying to do and I can see that being able to make more fixes post release has value for some use cases. My concern is that "things that do not destabilize the branch" is fairly subjective and also not always easy to ascertain beyond trivial changes. The only way I know to keep a code stable is to limit the updates. Also we need to clearly state what the constrains are for a post release commits so that every user can decide whether it works for them.

Olga

Agreed. The priority of a change is subjective as well.
My definition for inclusion on the release branch:
- Only bug fixes.
- Only if they have fairly understood repercussions (up to the committers
who +/-1 as usual).
- If we thought it would not break things but still does (CI or externally
reported failure) we revert it.
What do you want to add/change? Please reformulate those rules the way you
like and let's see how we can converge.
(Also, let's keep it short for clarity)

Hi Julien,

I think for us at Yahoo to be able to run our releases directly from the branch we would need the guarantees that I proposed in my initial email and something that we agreed to last year. The only changes that go in are

- Failures without reasonable workarounds
- Silent failures.

My main concerns with the proposal is that I do not believe that our current testing infra is robust/inclusive enough to catch errors. That's why I am hesitant in widening the scope.

I am fine with whatever the outcome the majority of people agrees with. I am just saying that Yahoo will likely need a private branch if our rules are too relaxed.

Olga,

A related but separate question: what do y'all do when there is a feature
that is finished, but for an upcoming release? ie a feature in trunk, but
not in 0.11 (which, let us assume, is stable).

Hi Jonathan,

I thought I answered your email last week but I just noticed that the answer did not come through.

We tell users that at is coming in the next release. Now that Pig is quite mature and stable, we don't see much of this. Having more frequent releases definitely helps in this respect.

Olga

Olga,

A related but separate question: what do y'all do when there is a feature
that is finished, but for an upcoming release? ie a feature in trunk, but
not in 0.11 (which, let us assume, is stable).

Hi Olga,

Daniel has cut the 0.10.1 branch and the release candidate is up for a vote. I think its reasonable to expect such releases where there are a lot of bug fixes. In 0.10.1 there are 48 fixes in all.

The list of bug fixes does not fit the criteria of being having no workaround or failing silently.

Does that work for?

Hi Jonathan,

I thought I answered your email last week but I just noticed that the answer did not come through.

We tell users that at is coming in the next release. Now that Pig is quite mature and stable, we don't see much of this. Having more frequent releases definitely helps in this respect.

Olga
