Splits the test app's build caching by context instead of running one remote
cache for both.
Locally, `expo run:*` caches the native build on disk via the
expo-build-disk-cache provider, keyed by the Expo fingerprint. A second run with
no native change reuses the first build; a screen edit never rebuilds, because
Metro serves JS. This is the original ask — "next time we don't build unless
native changes" — and needs no token, no network, and no custom provider.
In CI, test-app-build-cache.yml builds a Release binary per platform when the
fingerprint has no artifact yet, and publishes it as a GitHub Actions artifact
named `fingerprint.<hash>.<platform>`. Release, not dev-client, so the JS bundle
is embedded and a consuming job needs no Metro. setup-fixture-app installs it by
downloading the artifact and refreshing the JS with @expo/repack-app, so keying
on the native-only fingerprint stays correct — a JS-only change reuses the same
native binary in seconds. It falls back to an inline build when no artifact
exists yet, so a caller is never left without an app.
Release removes the sharp edges the dev-client cache needed. Its simulator .app
is universal (x86_64+arm64) rather than the active-arch-only slice a debug build
emits, so no architecture tag. It links against the SDK but loading is gated by
the deployment target, which the fingerprint already covers, so no toolchain
tag. And the CLI only narrows *debug* builds to the device ABI, so a Release APK
spans every ABI without the undocumented --all-arch flag. The artifact name
collapses to fingerprint plus platform.
This deletes build-cache-provider.js entirely — with it goes the custom Expo
provider that had to reach GitHub from inside @expo/cli, and every workaround
that forced: the fetch-nodeshim User-Agent shim, the arch/Xcode identity, the
upload-intent handoff. CI now talks to the artifacts API with plain `gh api`
outside the patched fetch, and locally the disk cache never hits the network.
The fingerprint comes from @expo/fingerprint's own `fingerprint:generate` (no
--platform, matching what @expo/cli hashes). Gitignoring /ios and /android is
what makes it machine-independent: the library asks the VCS whether the platform
markers are ignored and, concluding CNG, skips hashing them — so a developer's
prebuild output and a fresh CI checkout agree.
conformance-differential consumes setup-fixture-app, so it gains
`permissions: actions: read` for the artifact lookup.
The artifact lookup is non-fatal: a query outage leaves the id empty and
falls through to an inline build like a miss does, rather than exiting the
composite under set -e and turning a cache blip into a caller failure.
test/scripts/setup-fixture-app-fallback-smoke.sh drives that step's real shell
against a failing gh and asserts source=build; ci.yml runs it.
Move the scattered root-level native projects into per-platform folders and drop
the now-redundant platform prefix:
- android-ime-helper/ -> android/ime-helper/
- android-multitouch-helper/ -> android/multitouch-helper/
- android-snapshot-helper/ -> android/snapshot-helper/
- apple-runner/ -> apple/runner/
- macos-helper/ -> apple/macos-helper/
- src/platforms/linux/atspi-dump.py -> linux/atspi-dump.py
Only repo source paths move. Identity surfaces stay frozen so no user's runner
cache is invalidated on upgrade: the derived-cache key hashes source paths
relative to AgentDeviceRunner and excludes packageVersion, and the
~/.agent-device/{apple-runner,macos-helper} namespaces, the
agent-device-android-*-helper artifact/manifest/protocol names, the
AgentDeviceRunner Xcode project, and the `prepare ios-runner` CLI command are
unchanged. Updates build/package scripts, CI, package.json files+scripts,
ignore/attr/fallow configs, runtime path resolvers, and test fixtures.
Also: re-base repo-root-relative refs inside the moved apple/runner for the
added nesting level (gated XCUITest fixture walk + two doc links), and clean the
legacy dist/apple-runner packaged output so the relocated runner can't
double-ship into the wholesale-included dist (with a regression test).
