Task Kinds

This section lists and documents the available task kinds.

build

Builds are tasks that produce an installer or other output that can be run by users or automated tests. This is more restrictive than most definitions of “build” in a Mozilla context: it does not include tasks that run build-like actions for static analysis or to produce instrumented artifacts.

build-fat-aar

Build architecture-independent GeckoView AAR (Android ARchive) files. This build-like tasks is an artifact build (ARMv7, but this is arbitrary) that itself depends on arch-specific Android build jobs. It fetches arch-specific AAR files, extracts arch-specific libraries and preference files, and then assembles a multi-architecture “fat AAR”. Downstream consumers are expected to use per-ABI feature splits to produce arch-specific APKs.

If you want to run this task locally, you need to specify these environment variable:
  • MOZ_ANDROID_FAT_AAR_ARCHITECTURES: must be a comma-separated list of architecture. Eg: “armeabi-v7a,arm64-v8a,x86,x86_64”.

  • each of MOZ_ANDROID_FAT_AAR_ARM64_V8A, MOZ_ANDROID_FAT_AAR_ARMEABI_V7A, MOZ_ANDROID_FAT_AAR_X86, MOZ_ANDROID_FAT_AAR_X86_64 must be a path relative to MOZ_FETCHES_DIR.

build-signing

Many builds must be signed. The build-signing task takes the unsigned build kind artifacts and passes them through signingscriptworker to a signing server and returns signed results.

build-mac-signing

Mac signing without notarization.

Uses a self-signed certificate on level 1 environments.

Shippable downstream tasks should use artifacts from build-mac-notarization.

build-mac-notarization

Mac notarization on signingscript (linux) using rcodesign.

Only available in production environments, as Apple doesn’t offer a test endpoint for notarizing apps.

Downstream tasks switch to build-mac-signing in non-shippable builds or level 1 environments.

artifact-build

This kind performs an artifact build: one based on precompiled binaries discovered via the TaskCluster index. This task verifies that such builds continue to work correctly.

bootstrap

This kind performs a standalone bootstrap of a Firefox build from various system environments.

hazard

Hazard builds are similar to “regular’ builds, but use a compiler extension to extract a bunch of data from the build and then analyze that data looking for hazardous behaviors.

l10n

The l10n kind takes the last published nightly build, and generates localized builds from it. You can read more about how to trigger these on the wiki.

shippable-l10n

The nightly l10n kind repacks a specific nightly build (from the same source code) in order to provide localized versions of the same source.

shippable-l10n-signing

The shippable l10n signing kind takes artifacts from the shippable-l10n kind and passes them to signing servers to have their contents signed appropriately, based on an appropriate signing format. One signing job is created for each shippable-l10n job (usually chunked).

shippable-l10n-mac-signing

Mac signing without notarization.

Uses a self-signed certificate on level 1 environments.

Shippable downstream tasks should use artifacts from build-mac-notarization.

shippable-l10n-mac-notarization

Mac notarization on signingscript (linux) using rcodesign.

Only available in production environments, as Apple doesn’t offer a test endpoint for notarizing apps.

Downstream tasks switch to build-mac-signing in non-shippable builds or level 1 environments.

source-test

Source-tests are tasks that run directly from the Gecko source. This can include linting, unit tests, source-code analysis, or measurement work. While source-test tasks run from a source checkout, it is still possible for them to depend on a build artifact, though often they do not.

code-review

Publish issues found by source-test tasks on Phabricator. This is a part of Release Management code review Bot.

upload-symbols

Upload-symbols tasks run after builds and upload the symbols files generated by build tasks to Socorro for later use in crash analysis.

upload-symbols-dummy

Upload-symbols-dummy ensures both x64 and macosx64 tasks run for nightlies and releases.

upload-generated-sources

Upload-generated-sources tasks run after builds and upload source files that were generated as part of the build process to an s3 bucket for later use in links from crash reports or when debugging shipped builds.

upload-generated-sources-dummy

Upload-generated-sources-dummy ensures both x64 and macosx64 tasks run for nightlies and releases.

valgrind

Valgrind tasks produce builds instrumented by valgrind.

searchfox

Searchfox builds generate C++ index data for Searchfox.

static-analysis-autotest

Static analysis autotest utility in order to be sure that there is no regression when upgrading utilities that impact static-analysis.

toolchain

Toolchain builds create the compiler toolchains used to build Firefox. These will eventually be dependencies of the builds themselves, but for the moment are run manually via try pushes and the results uploaded to tooltool.

spidermonkey

Spidermonkey tasks check out the full gecko source tree, then compile only the spidermonkey portion. Each task runs specific tests after the build.

test

See the test kind documentation for more info.

docker-image

Tasks of the docker-image kind build the Docker images in which other Docker tasks run.

The tasks to generate each docker image have predictable labels: docker-image-<name>.

Docker images are built from subdirectories of taskcluster/docker, using docker build. There is currently no capability for one Docker image to depend on another in-tree docker image, without uploading the latter to a Docker repository.

balrog

Balrog tasks are responsible for submitting metadata to our update server (Balrog). They are typically downstream of a beetmover job that moves signed MARs somewhere (eg: beetmover and beetmover-l10n for releases, beetmover-repackage for nightlies).

beetmover

Beetmover, takes specific artifacts, “Beets”, and pushes them to a location outside of Taskcluster’s task artifacts, (archive.mozilla.org as one place) and in the process determines the final location and a “pretty” name (versioned product name)

beetmover-l10n

Beetmover L10n, takes specific artifacts, “Beets”, and pushes them to a location outside of Taskcluster’s task artifacts, (archive.mozilla.org as one place) and in the process determines the final location and a “pretty” name (versioned product name) This separate kind uses logic specific to localized artifacts, such as including the language in the final artifact names.

beetmover-repackage

Beetmover-repackage is beetmover but for tasks that need an intermediate step between signing and packaging, such as OSX. For more details see the definitions of the Beetmover kind above and the repackage kind below.

release-beetmover-push-to-release

release-source-checksums-signing take as input the checksums file generated by source-related beetmover task and sign it via the signing scriptworkers. Returns the same file signed and additional detached signature.

beetmover-checksums

Beetmover, takes specific artifact checksums and pushes it to a location outside of Taskcluster’s task artifacts (archive.mozilla.org as one place) and in the process determines the final location and “pretty” names it (version product name)

release-beetmover-source-checksums

Beetmover, takes source specific artifact checksums and pushes it to a location outside of Taskcluster’s task artifacts (archive.mozilla.org as one place) and in the process determines the final location and “pretty” names it (version product name)

release-balrog-submit-toplevel
