📝 Walkthrough

Walkthrough

The database service now rejects existing-database spec updates that change the Spock major version. Shared validation checks major components. Tests cover valid minor changes, invalid major changes, and host reassignment. Documentation describes the rejection.

Changes

Spock major-version validation

Layer / File(s) Summary
Version validation and documentation
server/internal/database/service.go, docs/using/image-management.md
ValidateChangedSpec checks Spock major versions independently. checkMajorUnchanged provides shared major-version validation and labeled errors. The documentation states that the Control Plane rejects Spock major-version changes.
Version validation tests
server/internal/database/service_test.go
Tests accept a PostgreSQL major-version change with host reassignment and a Spock minor-version change. Tests reject Spock major-version changes, including changes with host reassignment.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to c9837

Existing databases consistently reject Spock major-version changes while retaining valid omitted-version update behavior. No merge-blocking risk was identified.

The Spock major-version validation currently runs only when an instance ID matches between the current and updated specs. Since the instance ID is derived from hash(hostID, nodeName), changing a node's host_ids together with spock_version generates a new instance ID. As a result, no matching instance is found, the validation is skipped, and the Spock major-version change can go through unvalidated.

Since spock_version is database-wide and does not support per-node overrides, we should validate it once at the spec level by comparing current.SpockVersion with updated.SpockVersion, rather than validating it per instance. This would also prevent duplicate validation errors for multi-node updates.

We should also add tests covering the intended behavior:

  • Reject a Spock major-version change.
  • Allow a Spock minor-version change.

Move Spock major-version check into a single database-wide check in order to catch major version change being submitted alongside a HostID change.
