Nightly builds are automatically generated using a taskcluster cron task.
- The results of the latest successful nightly build is listed here: https://firefox-ci-tc.services.mozilla.com/tasks/index/project.application-services.v2.nightly/latest
- The latest nightly decision task should be listed here: https://firefox-ci-tc.services.mozilla.com/tasks/index/project.application-services.v2.branch.main.latest.taskgraph/decision-nightly
- If you don't see a decision task from the day before, then contact releng. It's likely that the cron decision task is broken.
Release builds are generated from the release-vXXX branches and triggered in Ship-it
- Whenever a commit is pushed to a release branch, we build candidate artifacts. These artifacts are shippable -- if we decide that the release is ready, they just need to be copied to the correct location.
- The
pushphase ofrelease-promotioncopies the candidate to a staging location where they can be tested. - The
shipphase ofrelease-promotioncopies the candidate to their final, published, location.
This part is 100% covered by the Release Management team. The dev team should not perform these steps.
This is documented under Release Management/Release Process Checklist Documentation, see application-services steps under Beta Merge Day steps
If you want to uplift changes into a previous release:
- Make sure the changes are present in
mainand have been thoroughly tested - Find the PR for the changes and add this comment:
@mergify backport release-vXXX - Find the Bugzilla bug with the changes and add an uplift request
- Find the attacment corresponding to new PR created from the
@mergifycomment. - Click the "details" link
- Set
approval-mozilla-betaorapproval-mozilla-releaseto? - Save the form
- Find the attacment corresponding to new PR created from the
- Release management will then:
- Arrange for the backport to be merged
- Create a new Application Services release in Ship-It for the release branch. Promote & ship the release
- Tag the release in the Application Services repo
- Notify the Application Services team in case there is a need to cut a new release of rust-components-swift
- Notify any affected consumer applications teams.
We build several artifacts for both nightlies and releases:
nightly.json/release.json. This is a JSON file containing metadata from successful builds. The metadata for the latest successful build can be found from a taskcluster index: https://firefox-ci-tc.services.mozilla.com/api/index/v1/task/project.application-services.v2.release.latest/artifacts/public%2Fbuild%2Frelease.json The JSON file contains:- The version number for the nightly/release
- The git commit ID
- The maven channel for Kotlin packages:
maven-production: https://maven.mozilla.org/?prefix=maven2/org/mozilla/appservices/maven-nightly-production: https://maven.mozilla.org/?prefix=maven2/org/mozilla/appservices/nightly/maven-staging: https://maven-default.stage.mozaws.net/?prefix=maven2/org/mozilla/appservices/maven-nightly-staging: https://maven-default.stage.mozaws.net/?prefix=maven2/org/mozilla/appservices/nightly/

For nightly builds, consumers get the artifacts directly from the taskcluster.
- For,
firefox-android, the nightlies are handled by relbot - For,
firefox-ios, the nightlies are consumed by rust-components-swift.rust-components-swiftmakes a github release, which is picked up by a Github action in firefox-ios
For real releases, we use the taskcluster release-promotion action. Release promotion happens in two phases:
promotecopies the artifacts from taskcluster and moves them to a staging area. This allows for testing the consumer apps with the artifacts.shipcopies the artifacts from the staging area to archive.mozilla.org, which serves as their permanent storage area.
