Summary by CodeRabbit

• Bug Fixes

  • Improved compatibility handling for fractional route and upstream retry timeouts based on dashboard version.
  • Older dashboard versions now reject unsupported fractional-timeout configurations, while supported versions preserve them accurately.

• Tests

  • Added coverage for dashboard version boundaries and fractional-timeout behavior.
  • Added an end-to-end regression test for route and upstream retry timeouts.

📝 Walkthrough

Walkthrough

The route resource tests now detect dashboard support for fractional timeouts. An ignored end-to-end test checks rejection on unsupported versions and unchanged round trips on supported versions. Unit tests cover dashboard version boundaries and development versions.

Changes

Fractional timeout compatibility

Layer / File(s)	Summary
Version-gated timeout validation and regression coverage rust/crates/adc-backend-api7/tests/e2e_resource_route.rs	The tests gate fractional route and upstream retry timeouts by dashboard version. Unsupported versions reject and clean up the payload. Supported versions preserve the values through a round trip. Unit tests cover the 3.9 and 3.10 patch thresholds, adjacent minor versions, later major versions, and the development placeholder version.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 7196b

The new end-to-end coverage is localized, but cleanup can leave test resources behind and prerelease versions may be classified incorrectly at backport boundaries; the PR is mergeable with explicit owner follow-up on these bounded test-correctness risks.

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
E2e Test Quality Review	⚠️ Warning	The new lower-version branch discards sync_events(...).await with let _; the helper returns Result<...>, so a cleanup error is explicitly ignored.	Handle the cleanup result explicitly, for example assert it succeeds or report the cleanup error and fail the test; do not assign the Result to _.

In `@rust/crates/adc-backend-api7/tests/e2e_resource_route.rs`:
- Around line 125-132: Update the rejection-path cleanup in the e2e resource
test to require sync_events for the service deletion to succeed rather than
discarding its result. After cleanup, assert that the backend configuration is
empty before returning, preserving the existing atomic-failure validation.
- Around line 70-76: Update dashboard_supports_fractional_timeout to compare the
complete Version value against Version::new(3, 9, 19) and Version::new(3, 10,
6), so prerelease versions remain below the release thresholds; add tests
covering both prerelease boundary cases.
