The workflow calls owned_build_state.py save STORE PACKAGES WORKSPACE, which is five argv entries, but main() matched four. So the step printed usage and exited 2, as in run 36064525977 (job 107851683549) and run 36067735445 (job 107862186541). An owned Mac never kept its resolved packages. The step is continue-on-error, so it failed no job.

  • Fix: len(argv) == 5 for save.
  • New test: WorkflowCommandLines runs every owned_build_state.py command line from ci-macos.yml as written against a scratch store, and requires exit 0. With the old check it fails on "Keep this owned Mac's build state".

tests/test_ci_owned_build_state.py (19 tests) passes locally.

Summary by cubic

Fixes the owned build state save step so it accepts the five arguments the workflow passes; owned Macs now keep their resolved packages in CI. Previously the script matched only four argv entries, so the step printed usage and exited 2, silently, because the step is continue-on-error.

  • Matches len(argv) == 5 for the save command.
  • Adds tests that run every owned_build_state.py command from ci-macos.yml against a scratch store and require exit 0.

Written for commit ff0a667. Summary will update on new commits.

Summary by CodeRabbit

  • Bug Fixes
    • Updated build-state saving to accept the workspace path, allowing the relevant workflow commands to run successfully. Calls using the previous argument format now display usage information.
  • Tests
    • Added checks that the macOS compile workflow’s build-state commands run successfully.

The workflow calls `owned_build_state.py save STORE PACKAGES WORKSPACE`,
five argv entries, but main() matched four, so the step printed usage
and exited 2 (run 36064525977, job 107851683549) and an owned Mac never
kept its resolved packages. A new test runs every owned_build_state.py
command line of the workflow as written against a scratch store.

📝 Walkthrough

Walkthrough

The save command now requires four arguments after the script name and passes the source-packages path and workspace to save. A workflow integration test runs each of the four calls and checks for successful execution.

Changes

Owned build state save dispatch

Layer / File(s) Summary
Save command dispatch and workflow validation
scripts/ci/owned_build_state.py, tests/test_ci_owned_build_state.py
The save command dispatch accepts four arguments after the script name and passes the source-packages path and workspace to save. The integration test executes all four workflow calls and checks their exit status and output.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to ff0a6

The save command appears ready to merge, but the new workflow test would not catch a failure to retain packages. Add a package fixture and persistence assertion to protect that behavior.

Add a source-packages fixture to the workflow test.

The test runs the workflow’s save command with base/src/.ci-source-packages, but that directory does not exist. save returns exit 0 with packages: false when no candidate exists. Therefore, the test cannot detect a wrong source-packages path or failed persistence. Create a package fixture before the loop, then assert that the save step leaves it under store/source-packages.

* ci: route CI helper and ci-macos.yml edits to the lanes that run them

* ci: close the routing review's under-selection gaps

- An input key with a trailing comment still opens its own input; a
  flow-style or unreadable one at that indent answers every job.
- A Linux job reads area outputs anywhere in its block (folded or step
  conditions), maps outputs derived from macOS to macOS, and runs every
  area when it waits on another job or reads an output this cannot place.
- The routing tables' imports still run a helper; only their path lists
  are dead ends.
- A helper the Swift package lane runs selects every area, since that lane
  is chosen by package path.
- `#!` lines are not comments.
