Release Process [obsolete]

This page documents the release process for MariaDB.

Release Steps

1. Developers commit fixes/features/etc into the appropriate tree until Buildbot looks OK (as determined by the Release Coordinator)
   • branch=10.2
   • branch=10.3
   • branch=10.4
   • branch=10.5
   • branch=10.6
   • branch=10.7
   • branch=10.8

2. The Buildbot buildslaves build packages and the Release Coordinator informs the Release Manager by creating a TODO in Jira and maybe posting a message in Slack

3. Buildbot builds the packages and when they are ready, or nearly ready, the Release Coordinator notifies the following of the tree, revision, and build number (tarbuildnum, see Note 7, below):
   1. The Release Manager (dbart)
   2. The Maria Dev team (maria-developers [at] lists (dot) launchpad (dot) net)
   3. The community team (community [at] mariadb (dot) org)

4. The Release Manager preps initial release notes and changelog pages for the release and sends these out to the MariaDB packagers list and the marketing team.

5. The Release Manager logs in to the buildmaster and runs the prep script. This script is found in the mariadb.org-tools repo on GitHub under the release directory. The script prepares the release directory which contains the generic Linux binaries, the Windows builds, and the YUM and APT repositories. Notes 5 and 6 describe the basic process for creating repositories, but the script handles the creation automatically.

~/src/mariadb.org-tools/release/prep -yl \
  -t 10.0 -v 10.0.20 -b 8266 \
  -r a6087e7dc1ef3561d8189c8db15e9591d0f9b520

6. Once the prep script is finished, files are uploaded to osuosl (the prep script offers to do this automatically) then a trigger script is run on the osuosl server to push the new files out to the public server:

   ./trigger-mariadb
   

7. Packages get uploaded to mirrors automatically depending on when they next pull from the osuosl mirror.

8. The Release Manager imports the new release into the MariaDB.org Download system and MariaDB.com download system

9. The Release Manager, with assistance from the Docs team, fills in, edits, and finishes the release notes and changelog pages (see Note 4) and removes the unreleased template (if it is there)

10. The Docs team creates release notes and changelog pages for the next release (so that the developers can fill them in as they work on the release)
    • The unreleased banner should be placed on these pages to let users know that the information on the page is about an unreleased version. The creole syntax for including the template is: <<include slug="unreleased">>

11. The Docs team preps updates to other documentation as necessary
    • Check with the Release Coordinator to see if there are any new features that should be added to the series pages (links below)

12. The Release Coordinator (or the Release Manager) adds a release tag to the release tree (e.g. mariadb-10.1.23 for the 10.1.23 release, see Note 1, below, for sample command lines).

13. Once all packages have been mirrored, the Release Manager activates the new release on the MariaDB Downloads page and activates any other documentation changes/additions
    • Use the "Check Mirrors" feature of the downloads system to check if the files are fully mirrored.

14. Check the MariaDB Deprecation Policy page to see if this will be the last release for any platforms. Be sure to mention them in the Release Notes and in the Announce emails. Update the page as necessary. After the release is out, edit the buildbot config to turn them off. Do not remove the VMs.

15. If the release is done from the bb-XXX-release branch, then for all MDEVs pushed into XXX after bb-XXX-release was forked:
    • major=10.5
    • git log bb-${major}-release..${major}
    • Change the FixVersion to the next release in Jira for all the MDEVs that show up
    • For example, any MDEV in `git log bb-10.5-release..10.5` for the 10.5.4 release should have 10.5.5 in the FixVersion, not 10.5.4

16. The Release Manager marks the release as "released" in JIRA. Before doing so, create a follow up release, if it doesn't already exist.

17. Announce the release
    1. Consolidate release announcements when possible (e.g. one release email for a set of 5.5/10.0/10.1 releases in a single week).
    2. The Release Manager or Docs team updates (as applicable):
       1. the applicable "What is MariaDB x.x" page with the new version (both the list of releases and the page excerpt)
          • What is MariaDB 10.8?
          • What is MariaDB 10.7?
          • What is MariaDB 10.6?
          • What is MariaDB 10.5?
          • What is MariaDB 10.4?
          • What is MariaDB 10.3?
          • What is MariaDB 10.2?
          • What is MariaDB Galera Cluster?
          • About the MariaDB Java Client
    3. Update the 'latest' template for the release, and include it at the top of the previous release's release notes page (e.g. with '<<include slug="latest-55">>'):
       • latest-108
       • latest-107
       • latest-106
       • latest-105
       • latest-104
       • latest-103
       • latest-102
       • latest-101
       • latest-galera-wsrep
       • latest-java
    4. An IRC op (dbart, etc...) updates the topic in #maria (if release is the current stable)
    5. The Release Manager announces the release on the announce and maria-discuss mailing lists, and via blogs and other methods (e.g. Facebook, Twitter, Google+, & LinkedIn)
    6. For major releases, an announcement will also be sent out as a press release

Notes

Note 1: Tagging releases and bumping the VERSION

Here is an example git command line to make the tag and bump the tree to the next version:

main=10.2
cur=38 # minor version of *current* release
rev=abc123 # hash of the release commit revision
tree=bb-${main}-release # release tree, e.g. bb-10.2-release
cd ~/src/mariadb/server

# first tag the release
git checkout ${tree}
git pull
git tag mariadb-${main}.${cur} ${hash} ; git push origin mariadb-${main}.${cur}

# second bump the VERSION, we do this in the main tree, not the release tree
git checkout ${main}
git pull
git checkout bb-${main}-bumpversion
git rebase ${main}
vi VERSION # increment the PATCH version number
git commit -a -m "bump the VERSION"
git push origin
while :; do sleep 60;git push origin bb-${main}-bumpversion:${main}; done
# watch the output until you start seeing "Everything up-to-date" messages, then Ctrl+c to exit
git checkout ${main}
git pull
git checkout bb-${main}-bumpversion
git rebase ${main}
git push origin

The bb-*-bumpversion branches were initially created like so:

cd ~/src/mariadb/server
git checkout ${main}
git pull
git checkout -b bb-${main}-bumpversion
git push --set-upstream origin bb-${main}-bumpversion

Note 2: Creating md5sums

Here are the commands I (Daniel) use to create the md5sums of a release:

cd /path/to/dir/with/releases/
release='mariadb-5.2.1-beta'
for dir in $(find ${PWD}/${release} -type d); do echo; echo ${dir};cd ${dir};md5sum *;echo;echo;done

Note 3: Obtaining info for Changelog and Release Notes (BZR):

A raw log of all changes can be obtained from bzr as follows:

sourcedir="5.1"
oldrelease="mariadb-5.1.44b"
newrelease="mariadb-5.1.47"
bzr branch --no-tree -rtag:${oldrelease} ${sourcedir} ${oldrelease}
bzr branch --no-tree -rtag:${newrelease} ${sourcedir} ${newrelease}
cd ${newrelease}/
bzr missing --kb-short --include-merged ../${oldrelease} > /tmp/short.txt
bzr missing --kb-long --include-merged ../${oldrelease} > /tmp/long.txt

Assuming that you have kbchangelog bzr plugin, this will generate a list of changes that uses Wiki Creole syntax and is ready to be pasted into the corresponding Changelog page. It might need a little bit of manual polishing, though. if there is no ${oldrelease} then do the following:

cd ${newrelease}/
bzr log --kb-short --include-merged >  /tmp/short.txt
bzr log --kb-long --include-merged >  /tmp/long.txt

Note 4: Obtaining info for Changelog and Release Notes (Git):

A raw log of all changes can be obtained from git as follows:

Note 5: Creating Debian and Ubuntu Repositories:

Prior to doing this, branch mariadb-tools from Launchpad:

bzr branch lp:mariadb-tools/trunk mariadb-tools

(or update a previously branched copy with "bzr pull").

1. Copy the build over to a working directory.

2. Run the following commands:

mkdir repo
cd repo
eval $(gpg-agent --daemon)
path/to/mariadb-tools/buildbot/mkrepo-debian.sh debian path/to/build-buildnum
path/to/mariadb-tools/buildbot/mkrepo-ubuntu.sh ubuntu path/to/build-buildnum
cd ../

3. On the osuosl mirror, move the old repo/5.x dir and upload the new repo to repo/5.x

scp -r repo osuosl:data/repo/5.2

4. Clean up your working directory by removing the local repo and build-### directories

Note 6: Signing RPM Packages and Creating the YUM repositories:

1. Prior to beginning, ensure that you have a .rpmmacros file with the following contents (replace '<keyname>' with the actual key name):

%_signature gpg
%_gpg_path ~/.gnupg
%_gpg_name <keyname>
%_gpgbin /usr/bin/gpg

2. Create a directory for the files based on the major.minor release numbers (for example: 5.5)

3. cd into the directory

4. run the mkrepo-yum.sh script:

path/to/mariadb-tools/buildbot/mkrepo-yum.sh path to build-tarbuildnum

5. at certain points while the script runs you will be prompted for the signing key password

6. Upload the files to the primary mirror:

release="mariadb-5.5.24"
for dir in $(ls);do
  rsync -avP ${dir} osuosl:data/${release}/
done

7. Upload the files to the YUM repo server:

version="5.5"
for dir in $(ls);do
  rsync -avP ${dir} yum-repo-server:${version}/
done

8. Once uploaded, ssh to the yum repo server and move the files to their proper location, replacing the previous repo ${releasenum} dir.

Note 7: Determining build numbers for releases:

Build numbers come from Buildbot. To get the build number for a specific buid, e.g. for MariaDB 10.1 builds:

1. Look at the columns here. The headers across the top list the branch (10.1 in this case) and the revision hashes for the last few builds.

2. Pick the column that corresponds to the revision hash with the with the correct release tag

3. Select one of the builds in the correct column and look for the property "tarbuildnum". This is the build-### directory you want.
