Release Process¶

Autopush has a regular 2-3 week release to production depending on developer and QA availability. The developer creating a release should handle all aspects of the following process as they’re done closely in order and time.

Versions¶

Autopush uses a {major}.{minor}.{patch} version scheme, new {major} versions are only issued if backwards compatibility is affected. Patch versions are used if a critical bug occurs after production deployment that requires a bug fix immediately.

Dev Releases¶

When changes are committed to the master branch, an operations Jenkins instance will build and deploy the code automatically to the dev environment.

The development environment can be verified at its endpoint/wss endpoints:

Websocket: wss://autopush.dev.mozaws.net/
Endpoint: https://updates-autopush.dev.mozaws.net/

Stage/Production Releases¶

Pre-Requisites¶

To create a release, you will need appropriate access to the autopush GitHub repository with push permission.

You will also need clog installed to create the CHANGELOG.md update.

Release Steps¶

In these steps, the {version} refers to the full version of the release.

i.e. If a new minor version is being released after 1.21.0, the {version} would be 1.22.0.

Switch to the master branch of autopush.
git pull to ensure the local copy is completely up-to-date.
git diff origin/master to ensure there are no local staged or uncommited changes.
Run tox locally to ensure no artifacts or other local changes that might break tests have been introduced.
Change to the release branch.

If this is a new major/minor release, git checkout -b release/{major}.{minor} to create a new release branch.

If this is a new patch release, you will first need to ensure you have the minor release branch checked out, then:
1. git checkout release/{major}.{minor}
2. git pull to ensure the branch is up-to-date.
3. git merge master to merge the new changes into the release branch.
Note that the release branch does not include a ``{patch}`` component.
Edit autopush/__init__.py so that the version number reflects the desired release version.
Run clog --setversion {version}, verify changes were properly accounted for in CHANGELOG.md.
git add CHANGELOG.md autopush/__init__.py to add the two changes to the new release commit.
git commit -m "chore: tag {version}" to commit the new version and record of changes.
git tag -s -m "chore: tag {version}" {version} to create a signed tag of the current HEAD commit for release.
git push --set-upstream origin release/{major}.{minor} to push the commits to a new origin release branch.
git push --tags origin release/{major}.{minor} to push the tags to the release branch.
Submit a pull request on github to merge the release branch to master.
Go to the autopush releases page, you should see the new tag with no release information under it.
Click the Draft a new release button.
Enter the tag for Tag version.
Copy/paste the changes from CHANGELOG.md into the release description omitting the top 2 lines (the a name HTML and the version) of the file.

Keep these changes handy, you’ll need them again shortly.
Once the release branch pull request is approved and merged, click Publish Release.
File a bug for stage deployment in Bugzilla, in the Cloud Services product, under the Operations: Deployment Requests component. It should be titled Please deploy autopush {major}.{minor} to STAGE and include the changes in the Description along with any additional instructions to operations regarding deployment changes and special test cases if needed for QA to verify.

At this point, QA will take-over, verify stage, and create a production deployment Bugzilla ticket. QA will also schedule production deployment for the release.
