Open Shorebird Workspace

This repository is a meta-workspace for the open Shorebird replacement work. It pins the source repositories used by the SDK, Flutter/engine, CLI, updater, and self-hosted server work as git submodules, while keeping local test fixtures and platform scripts in this root repository.

Submodules

Path	Role	Remote	Branch
dart-sdk-new	Dart SDK fork with AOT patch runtime work	https://git.tonycloud.org/dart-lang/sdk.git	tonycloud/dev
flutter	Flutter fork used by app and engine integration tests; engine sources live under flutter/engine/src/flutter	https://git.tonycloud.org/flutter/flutter.git	shorebird/dev
shorebird	CLI, protocol/client packages, open patch tools	https://git.tonycloud.org/flutter/shorebird.git	main
shorebird-server	Self-hosted CodePush/auth/management server	https://git.tonycloud.org/flutter/shorebird-server.git	main
updater	Runtime updater and patch package tooling	https://git.tonycloud.org/flutter/shorebird-updater.git	main
depot_tools	Chromium/Dart checkout tooling	https://chromium.googlesource.com/chromium/tools/depot_tools.git	main

The Dart SDK checkout has additional gclient-managed dependencies under dart-sdk-new/third_party. They are intentionally not top-level submodules.

First Checkout

git submodule update --init --recursive

For Linux:

./scripts/bootstrap_linux.sh

For macOS and iOS-preparation checks:

./scripts/bootstrap_macos.sh

By default the bootstrap scripts run gclient sync, which can download a large toolchain/dependency set. Set SKIP_GCLIENT_SYNC=1 when the checkout is already synced or when you only want source-level tests.

GitHub CI

The root workflow .github/workflows/open-shorebird-ci.yml is the upload-ready CI entry point for the combined workspace. Default push and pull request runs execute source-level checks and build distributable CLI/server artifacts:

• compiled shorebird, open_aot_patch_tools, and artifact_proxy archives for Linux x64, macOS x64/arm64, and Windows x64
• public updater patch-*.zip mirror artifacts for the CLI cache
• mirror-metadata with artifacts_manifest.yaml for the artifact proxy
• self-hosted shorebird-server archives for Linux, macOS, and Windows

Manual workflow_dispatch runs with full_sdk_build=true build the large SDK and engine outputs: patched Dart SDK archives for Linux x64 and macOS arm64, Linux x64 desktop engine artifacts, Android arm64 engine artifacts, Flutter web SDK artifacts, and Apple iOS/macOS engine artifacts. A successful full SDK run also uploads open-shorebird-artifact-mirror, a publish-ready mirror archive assembled from the produced patch-tool, metadata, engine, and web artifacts, plus open-shorebird-release-manifest, a checksum-verified provenance index for the CLI, server, SDK, engine, and mirror archives. Use scripts/validate_release_manifest.py to audit a downloaded manifest against the downloaded workflow artifacts before publishing or mirroring them. The wrapper scripts/verify_downloaded_release_artifacts.sh runs that manifest sidecar check, verifies the mirror archive sidecar, and validates the extracted artifact mirror from a downloaded workflow run. Before pushing the workspace and submodule forks, run scripts/verify_upload_readiness.sh; it fails if any required CI support file is untracked or if a required root/submodule checkout still has uncommitted changes. After upload, scripts/verify_hosted_full_sdk_build.sh --repo owner/repo --ref main dispatches the hosted full SDK workflow, waits for it, downloads artifacts, and runs the downloaded-release verifier. The heavy SDK/engine jobs default to custom runner labels open-shorebird-linux-heavy and open-shorebird-macos-heavy, then run an early disk-capacity preflight. Register larger/self-hosted runners with those labels or override linux_heavy_runner / macos_heavy_runner at dispatch time. The dispatch inputs sdk_min_free_disk_gb and engine_min_free_disk_gb control the preflight thresholds. The CI contract is validated by scripts/verify_ci_workflow.sh; it rejects dart_dynamic_modules=true, legacy aot-tools.dill publishing, missing checksum sidecars, and missing required artifacts. Manual workflow_dispatch runs with run_runtime_smokes=true run the Android and Linux seeded runtime patch smokes on provisioned runners. These jobs are not part of default push/PR CI because they require local engine build directories; the Android smoke also requires an attached device or emulator. The open CLI defaults vended Flutter installs to this workspace's open Flutter fork and can be pointed at a future GitHub mirror with SHOREBIRD_FLUTTER_GIT_URL. When no base_url or hosted URL override is configured, API/auth traffic defaults to the local self-hosted server at http://localhost:8080 instead of Shorebird's hosted service. The bundled updater library uses the same default when shorebird.yaml does not include base_url. CLI-managed patch-tool artifact downloads default to the local open mirror root http://localhost:8080/artifacts; set SHOREBIRD_ARTIFACT_BASE_URL for a public mirror populated with the CI-produced patch-*.zip files and artifacts_manifest.yaml. The patch artifacts and manual engine artifacts include publish-ready shorebird/ mirror subtrees that can be copied to that same mirror root. Full SDK workflow runs upload the already assembled open-shorebird-artifact-mirror archive; after downloading workflow artifacts manually, use scripts/assemble_artifact_mirror.sh <downloaded-artifacts-dir> <mirror-root> to merge those subtrees, reject conflicting artifact bytes, validate artifacts_manifest.yaml overrides, verify all platform patch-*.zip files, and write missing checksum sidecars. If your open engine revision differs from the upstream Flutter engine revision used for unchanged artifacts, set the workflow base_flutter_engine_revision input when generating mirror metadata. Vended Flutter commands receive FLUTTER_STORAGE_BASE_URL from SHOREBIRD_FLUTTER_STORAGE_BASE_URL, falling back to http://localhost:8080/download.flutter.io for local self-hosted artifacts. The Flutter fork itself uses that same open mirror as its default engine and Android Maven artifact host when FLUTTER_STORAGE_BASE_URL is unset, including its Dart SDK refresh scripts.

The iOS App Store candidate route is the encrypted Dart bytecode interpreter path, not native AOT patch loading. Real-device testing on June 25, 2026 showed the patched iPad app displaying license:pro without enabling DART_DYNAMIC_MODULES. The macOS native-AOT desktop route was also verified locally the same day by launching a saved free app with a pro Flutter snapshot seeded as patch 1; the patched app reported license:pro. CI builds Linux, Android, and macOS engine artifacts with the native AOT patch runtime enabled and the interpreter route disabled; iOS is the only App Store-safe interpreter patch artifact path. Android release APK builds pass locally with the custom Android engine; use scripts/android_runtime_patch_smoke.sh on a machine with an attached Android device or emulator to run the seeded runtime patch proof. Use scripts/linux_runtime_patch_smoke.sh on a Linux desktop runner to exercise the same saved-free-app/pro-patch flow for the Linux embedder.

Local Test Fixture

testapps/license_flavor_patch_test is kept in the root repository because it tests the open AOT patch and license/flavor behavior across the nested repos. Generated build output under that app is ignored by this meta-repository.
