REQ-HOST-3/REQ-HOST-4 require a MachineDataDb connection string for Central nodes.
The shipped docker appsettings (docker/central-node-a/appsettings.Central.json and
central-node-b) already carry the key. Host-008 had removed the fail-fast Require
because MachineDataDb had no consumer yet; this commit reverses that decision so a
misconfigured or missing connection string is caught at startup with a clear error.
Changes:
- DatabaseOptions: add MachineDataDb property with XML doc comment
- StartupValidator: add .Require for ScadaBridge:Database:MachineDataDb inside the
existing Central .When block, immediately after the ConfigurationDb Require
- StartupValidatorTests: rename Central_MissingMachineDataDb_PassesValidation ->
FailsValidation and flip to Assert.Throws; update comment to cite REQ-HOST-3/4,
shipped docker appsettings, and the Host-008 reversal; add MachineDataDb to
ValidCentralConfig() so all other Central tests remain green
- CentralDbTestEnvironment: supply ScadaBridge__Database__MachineDataDb env var
(mirrors ConfigurationDb pattern) so HostStartupTests, HealthCheckTests, and
MetricsEndpointTests pass through the new Require
- CompositionRootTests, AkkaHostedServiceAuditWiringTests, ActorPathTests: set
ScadaBridge__Database__MachineDataDb env var alongside the pepper env var and
clear it in Dispose, matching the existing pepper handling pattern
Build: 0 warnings, 0 errors. dotnet test Host.Tests: 233/233 passed.
