Rationale: keeping it in one step keeps the `result` output local and avoids an inter-step file-handoff dance. CUE is used where it adds value (typed JSON manipulation, schema validation) and bash is used where it's natural (HTTP, comparison, `$GITHUB_OUTPUT`). A pure-CUE pipeline would need a wrapper script anyway. + +Alternative considered: split into 4 steps mirroring the inline TODO comments. Rejected — every split needs an artifact or `$GITHUB_OUTPUT` plumbing for the next step, with no real benefit. + +### Decision 2: Source build-tools version with a CUE-aware shell step in job 2 + +The build-tools version comes from `https://raw.githubusercontent.com/flutter/flutter/refs/tags//engine/src/flutter/tools/android_sdk/packages.txt`. The current orphan step already does the curl+awk extraction. We give it an `id`, write to `$GITHUB_OUTPUT`, then plumb the value into the existing `script/update_test.sh` / CUE `version.json` generation path so it lands in `config/version.json`. + +Open implementation question (Open Question 1): the current `update_test.sh` derives `android_sdk_build_tools_version` from gradle output via `updateAndroidVersions.gradle.kts`. We need to choose whether `packages.txt` *replaces* the gradle source or *cross-checks* it. Default: replace, since `packages.txt` is the upstream source of truth Flutter itself uses. + +Alternative considered: query the gradle plugin only and trust it. Rejected — the user explicitly asked for `packages.txt` as the source. + +### Decision 3: Channel restricted to `"stable"` in the schema + +`config/schema.cue#FlutterVersion.flutter.channel` becomes literal `"stable"` (not a disjunction). Rationale: the fetcher already filters by `^\d+\.\d+\.\d+$`, which stable-only releases match. The schema change makes that invariant explicit and rejects accidental beta/dev pins at validation time. + +Alternative considered: keep `"stable" | "beta"`. Rejected — user confirmed stable-only is intentional. + +### Decision 4: Keep `script/copyFlutterVersion.js`, delete `script/updateFlutterVersion.js` + +Only the **fetch + compare** is migrating to CUE. The merge of `flutter_version.json` into `version.json` (job 2 step) stays as-is. Rationale: scope. The branch's goal as named (`single_update`) is the fetch path; broadening scope to also rewrite the merge would multiply the change surface for no user-visible benefit. + +### Decision 5: Output `result` as a step output, not a job output value derived from artifact presence + +The old job-2 `if:` gate reads `needs.update_flutter_version.outputs.new_version`, which today maps to `steps.update_flutter_version.outputs.result`.

Could not verify live (sandbox network timeouts to googleapis). → **Mitigation:** the implementation step runs `cue eval` with a smoke value and a fallback to `--list` mode; if the shape is different, implementer iterates locally with `mise use cue@0.15.0`. + +- **[Risk] `packages.txt` format changes.** A future Flutter version could split `build-tools` into multiple lines or change the `;` delimiter. Today: `grep 'build-tools' | awk -F'[;:]' '{print $2}'`. → **Mitigation:** if the extraction returns empty or a non-semver string, the CUE schema (`buildTools!: #SemverPatch`) rejects it at the `validate_config_version` job, failing loudly rather than silently shipping a bad image. + +- **[Risk] First post-merge run produces a large PR (potentially several Flutter versions worth of catch-up).** The repo has been unable to bump versions while this branch was broken. → **Mitigation:** none needed — that's the desired behavior; the maintainer reviews and merges as normal. + +- **[Trade-off] CUE installed twice in the workflow (job 1 host, job 2 container) and shell logic in job 1.** The job-2 install is unavoidable (different runner).

Two trigger paths to exercise: (i) immediately, expecting either `true`-path-to-PR or `false`-path-to-clean-skip depending on whether main is current; (ii) after artificially rewinding `config/flutter_version.json` to an older version on the branch, expecting `true` path through to PR creation. +- Critical path under test: job-1 step output → job-2 gate → `validate_config_version` `cue vet` → job-4 PR title/commit message non-empty. +- No new test infrastructure required. + +## Observability + +- The new fetch step `echo`s the old version, the new version, and the comparison verdict before writing `$GITHUB_OUTPUT`.

The first scheduled run after merge produces a PR for whatever Flutter version is current upstream. The next run is a no-op until upstream ships another stable release. diff --git a/openspec/changes/archive/2026-05-09-finish-cue-version-update/specs/flutter-version-update/spec.md b/openspec/changes/archive/2026-05-09-finish-cue-version-update/specs/flutter-version-update/spec.md new file mode 100644 index 0000000..79fc376 --- /dev/null +++ b/openspec/changes/archive/2026-05-09-finish-cue-version-update/specs/flutter-version-update/spec.md @@ -0,0 +1,90 @@ +## ADDED Requirements + +### Requirement: Scheduled run opens an upgrade PR when a new stable Flutter is released + +The `update_version.yml` workflow SHALL open exactly one pull request titled `chore(release): upgrade flutter to ` whenever the latest entry in `https://storage.googleapis.com/flutter_infra_release/releases/releases_linux.json` matching the stable channel and a `\d+.\d+.\d+` version differs from the version currently pinned in `config/flutter_version.json`. + +The experience context is the CI engineer who watches this repository for upgrade PRs to merge into their image fork. + +#### Scenario: Upstream ships a new stable Flutter + +- **GIVEN** `config/flutter_version.json` pins Flutter `X.Y.Z` +- **AND** the latest stable release in `releases_linux.json` is `X.Y.Z+1` +- **WHEN** the scheduled run of `update_version.yml` executes +- **THEN** a branch `update-flutter-dependencies/X.Y.Z+1` is pushed +- **AND** a pull request is opened with title `chore(release): upgrade flutter to X.Y.Z+1` +- **AND** the commit message on that PR equals the title (non-empty) + +#### Scenario: No upstream change since last run + +- **GIVEN** `config/flutter_version.json` already pins the latest stable Flutter version +- **WHEN** the scheduled run of `update_version.yml` executes +- **THEN** no branch is created +- **AND** no pull request is opened +- **AND** all jobs after `update_flutter_version` are skipped + +### Requirement: Upgrade PR contains a coherent, validated `version.json` + +When the workflow opens an upgrade PR, the included `config/version.json` SHALL satisfy `cue vet config/schema.cue -d '#Version'` and SHALL contain the Android `buildTools.version` listed for that exact Flutter tag in `engine/src/flutter/tools/android_sdk/packages.txt` upstream. + +The experience context is the CI engineer reviewing or merging the upgrade PR — they observe that downstream image builds will not silently regress on Android tooling. + +#### Scenario: Build-tools version tracks the new Flutter tag + +- **GIVEN** the workflow is opening an upgrade PR for Flutter `X.Y.Z` +- **AND** Flutter's `engine/src/flutter/tools/android_sdk/packages.txt` at tag `X.Y.Z` lists `build-tools;A.B.C` +- **WHEN** the PR is created +- **THEN** `config/version.json` in the PR contains `android.buildTools.version == "A.B.C"` + +#### Scenario: Generated config is schema-valid + +- **GIVEN** the workflow has produced a candidate `config/version.json` +- **WHEN** the `validate_config_version` job runs +- **THEN** `cue vet config/schema.cue -d '#Version' config/version.json` exits 0 +- **AND** the workflow only proceeds to open the PR if validation passes + +### Requirement: Schema rejects non-stable Flutter channels + +`config/schema.cue` SHALL constrain `flutter.channel` to the literal `"stable"`.
