""" sdk.py - Builds, tests, and publishes Fuchsia SDKs.

# Execution overview

## Trigger companion image subbuilds

Optionally trigger companion images, which are built alongside the SDK to give
developers prebuilt images to test with.

## Trigger SDK subbuilds

Trigger x64 and arm64 subbuilds. We run them in parallel to speed up the build.
See https://fuchsia.dev/fuchsia-src/development/sdk#recipes for more info.

## Collect SDK subbuilds and merge archives

Invoke an in-tree script to merge the SDK archives produced by each SDK
subbuild, yielding the core SDK.

## Test the core SDK

Invoke an in-tree script to generate a bazel workspace using the core SDK, and
invoke bazel to run tests.

## Build the GN SDK

Invoke an in-tree script to generate the GN SDK based on the core SDK.
See https://fuchsia.dev/fuchsia-src/development/sdk/gn for more info.

## Test the GN SDK

Invoke an in-tree script to generate a bazel workspace using the GN SDK, and
invoke bazel to run tests.

## Collect companion image subbuilds

Collect companion images, if they were requested to be built.

## Publish

Publish the core and GN SDKs, and the optional companion images and associated
packages to GCS. Also publish the core and GN SDKs to CIPD. For official
releases, also apply refs e.g. "latest" to these uploads.

## Trigger external tests

Optionally trigger tests against an external CQ to test that the new SDK is
compatible.

## Collect external tests

If external tests were triggered, wait on CQ to complete, and report success or
fail.

## Trigger TAP tests

Optionally trigger tests against TAP to test that the new SDK is compatible.

## Collect TAP tests

If TAP tests were triggered, wait on TAP to complete and report success or fail.
