Since the release of [[ReleaseNotes/Diablo|Diablo]] on 2011-09-22, the <code><nowiki>stable/diablo</nowiki></code> branches of nova and glance have accumulated roughly 80 and 20 fixes respectively. The [https://launchpad.net/~openstack-stable-maint openstack-stable-maint] team have rigorously applied the documented [[StableBranch]] principles and have worked hard to include appropriate bugfixes from master while limiting the risk of regressions.

You can see a history of these releases on the [[Releases]] page.
  
At least Fedora and Ubuntu have been updating their packages from the stable branch and haven't seen any regressions. We feel the time is long past for [[OpenStack]] to prepare a 2011.3.1 update release from the branch.

The [[ReleaseTeam]] is responsible for all [[OpenStack]] release deliveries, but [[markmc]] will join the [[ReleaseTeam]] to specifically to help prepare the diablo update release.

# Versioning: push a change to <code><nowiki>master</nowiki></code> and <code><nowiki>stable/diablo</nowiki></code> to add a <code><nowiki>REVISION</nowiki></code> field to <code><nowiki>{NOVA,GLANCE}_VERSION</nowiki></code> e.g.  
+
=== Versioning ===
 +
 
 +
Make sure the current versioning on the stable branch of each project is correct - e.g. the version in <code><nowiki>setup.cfg</nowiki></code> is the same as the version you intend to release.
 +
 
 +
=== Tarballs ===
 +
 
 +
Make sure the tarballs job in Jenkins is building tarballs correctly for each project e.g. check [http://tarballs.openstack.org/nova/nova-stable-icehouse.tar.gz here for Nova Icehouse] that a tarball is being built from the stable branch each time a commit is pushed there.
 +
 
 +
=== Warn People ===
 +
 
 +
Discuss your plans for the release at the weekly project meeting.
 +
 
 +
Preferably set a date for the release immediately after the previous release.
 +
 
 +
=== Milestones ===
 +
 
 +
Create a launchpad milestone for each project for the version you're planning to release.
 +
 
 +
=== Bugs ===
 +
 
 +
Note: [https://bugs.launchpad.net/launchpad/+bug/1081197 only project drivers can target bugs to a series] so the release manager needs to find bugs tagged with '''in-stable-icehouse''' and target them.

This information is about coordinated releases from the stable branch up to OpenStack Kilo. For stable/liberty and later see [openstack-dev] [release] stable branch release process changes [1]

You can see a history of these releases on the Releases page.

Stable Branch Releases

How To Release

Below is the checklist of steps required to carry out this release, heavily based on ReleaseTeam/HowToRelease.

Versioning

Make sure the current versioning on the stable branch of each project is correct - e.g. the version in setup.cfg is the same as the version you intend to release.

Tarballs

Make sure the tarballs job in Jenkins is building tarballs correctly for each project e.g. check here for Nova Icehouse that a tarball is being built from the stable branch each time a commit is pushed there.

Warn People

Discuss your plans for the release at the weekly project meeting.

Preferably set a date for the release immediately after the previous release.

Milestones

Create a launchpad milestone for each project for the version you're planning to release.

Bugs

Note: only project drivers can target bugs to a series so the release manager needs to find bugs tagged with in-stable-icehouse and target them.

  1. Gather a list of bugs fixed since the previous release e.g.
    $> git log --no-merges --topo-order 2014.1.1.. | grep -i '\(bug\|lp\)[: #]*' | sed 's/.*\(1[0-9][0-9][0-9][0-9][0-9][0-9]\).*/\1/' > nova-bugs.txt
  2. Using scripts from http://github.com/markmc/openstack-lp-scripts sanity check the list of bugs. Check that each has had a patch proposed to the stable branch
    $> python showbugs.py $(cat nova-bugs.txt)
  3. Nominate those bugs for the series
    $> python nominate.py nova icehouse $(cat nova-bugs.txt)
  4. Target those bugs at the milestone
    $> python target.py nova icehouse 2014.1.2 $(cat nova-bugs.txt)
  5. Review the list of bugs targeted to the milestone and fixup Importance and Assignee fields e.g. https://bugs.launchpad.net/nova/+milestone/2014.1.1
  6. Review bugs tagged with in-stable-icehouse and target them appropriately if they haven't already been targeted. Don't forget to remove the tag. e.g. a query for nova
  7. Review bugs tagged with icehouse-backport-potential, untag fixes already backported and consider backporting important ones. e.g. a query for nova.
  8. Check to see if any bugs were nominated for the series
  9. Look at open reviews and make sure the corresponding bugs are targeted. e.g. query for nova.

Call For Testing

Call for testing, see this example

Tag

  1. Tag the release:
    $> git fetch gerrit; git tag -m 2014.1.2 -s 2014.1.2 gerrit/stable/icehouse
  2. Bump version in setup.cfg BEFORE pushing the tags e.g. https://review.openstack.org/#/q/I3a7170180717bd62fce4cbc2c3a9107187f89fb1,n,z
  3. Push the tags for each project
    $> git push gerrit tag 2014.1.2

Close bugs

  1. Using http://github.com/markmc/openstack-lp-scripts mark all FixCommitted bugs as FixReleased. With a small change:
+series = proj.getSeries(name='icehouse')
+bugtasks = series.searchTasks(status='Fix Committed', omit_targeted=False)

we can use process-fixcommitted-bugs.py:

$> python ./process-fixcommitted-bugs.py --onlymilestone 2014.1.2 --fixrelease nova

NB: script might fail updating bugs with lots of tasks e.g. bug 1251757 - skip them using optional "exceptions" parameters e.g.

$> python ./process-fixcommitted-bugs.py --onlymilestone 2013.2.1 --fixrelease nova 1257293 1251757

Upload The Release

Using http://github.com/openstack-infra/release-tools

  1. Upload the release:
$> python ./upload_release.py nova 2014.1.2

Once all done

  1. Write release notes like ReleaseNotes/2014.1.1
  2. Send release announcement like StableBranchRelease/BoilerPlateAnnounce.
  3. Propose an openstack/releases change, like https://review.openstack.org/210547

Rinse, Repeat

  1. Decide on date for next release, create milestones

Planned stable/juno releases (12 months)

2014.2.1  Dec 4 2014, release manager: apevec
2014.2.2  Feb 5 2015, release manager: zulcss
2014.2.3  Apr 9 2015, release manager: adam_g
2014.2.4 (eol) mid November, 2015. release manager: apevec

Planned stable/kilo releases (12 months)

  • 2015.1.1 July 16, 2015, release manager: apevec
  • 2015.1.2 mid-October, 2015, release manager: zulcss
  • 2015.1.3 ~January, 2016, release manager: Daviey
  • 2015.1.4 (eol) ~2016-05-02, release manager Daviey
