New per-admin-node actor that subscribes to the fleet-status DistributedPubSub
topic + forwards every FleetStatusChanged snapshot to all SignalR clients
connected to FleetStatusHub via IHubContext.
Wired via WithOtOpcUaSignalRBridges (new AkkaConfigurationBuilder extension in
AdminUI.Hubs) — Program.cs calls it inside the if(hasAdmin) block alongside
WithOtOpcUaControlPlaneSingletons.
Per-node subscription rather than cluster-singleton: every admin node forwards
its own snapshots to its own connected clients. Simpler than singleton
coordination + acceptable because the messages are small and SignalR fan-out
is per-node anyway.
- New Commons.Messages.Fleet.GetDiagnostics request record.
- DriverHostActor handles GetDiagnostics in all three states (Steady, Applying,
Stale); replies with a NodeDiagnosticsSnapshot built from _currentRevision
+ the local NodeId. Drivers list is empty until F7 wires the per-instance
children.
- FleetDiagnosticsClient now resolves the target via ActorSelection at
akka.tcp://{system}@{nodeId}/user/driver-host and Asks with a 3s timeout.
On timeout/peer-down it returns an empty snapshot so the UI degrades
gracefully rather than throwing.
Two new integration tests in Host.IntegrationTests:
- GetDiagnostics_returns_snapshot_with_target_NodeId verifies the
cross-node Ask/Reply works.
- GetDiagnostics_after_deploy_reports_current_revision exercises the
end-to-end path: AdminOps starts a deployment, both DriverHostActors
apply, then diagnostics reports the new revision on both nodes.
All 98 v2 tests pass (was 96 + 2 new).
Injects AuthenticationStateProvider and reads the current user's identity
name on Deploy click, replacing the "(current user)" placeholder.
Anonymous case falls back to "(anonymous)" — should never hit in practice
since the page requires FleetAdmin/ConfigEditor.
Task 56: removes the legacy in-process Server + Admin Web project + their test
projects (Server.Tests, Admin.Tests, Admin.E2ETests). The fused OtOpcUa.Host
binary built across Phases 1-9 is now the sole production entry point.
What happened to the 47 legacy Admin Blazor pages: per follow-up F15, the
v1 architecture's draft/publish UX is replaced by v2's live-edit + snapshot-
deploy model, so a 1:1 migration is not meaningful. The mechanical move via
git mv preserves the history; service classes + page bodies that referenced
removed v1 types (ConfigGeneration, RedundancyRole, GenerationId) were
deleted. AdminUI now ships a minimal Home page + the v2 Deployments page.
Per-page rebuild against the v2 surface is tracked as F15. The v2 Deployments
page (Task 52) is the only first-party UI shipping in this PR.
Task 57: solution build green; 84+ tests green across active v2 + legacy
driver test projects.
Adds the empty project skeletons that subsequent v2 tasks fill in:
src/Core/ZB.MOM.WW.OtOpcUa.Commons (types, interfaces, message contracts)
src/Core/ZB.MOM.WW.OtOpcUa.Cluster (Akka.Hosting + cluster wiring)
src/Server/ZB.MOM.WW.OtOpcUa.Security (cookie+JWT auth, LDAP)
src/Server/ZB.MOM.WW.OtOpcUa.ControlPlane (admin-role cluster singletons)
src/Server/ZB.MOM.WW.OtOpcUa.Runtime (per-node driver actors)
src/Server/ZB.MOM.WW.OtOpcUa.OpcUaServer (OPC UA SDK application host)
src/Server/ZB.MOM.WW.OtOpcUa.AdminUI (Razor class library)
src/Server/ZB.MOM.WW.OtOpcUa.Host (single fused web binary)
Each project sets TreatWarningsAsErrors=true in its own csproj (per the
Directory.Build.props deviation note in the previous commit). NuGetAuditSuppress
entries cover transitive vulnerability advisories the new strictness surfaces:
- GHSA-g94r-2vxg-569j (OpenTelemetry.Api 1.9.0 via Akka.Cluster.Hosting/Tools)
- GHSA-h958-fxgg-g7w3 (Opc.Ua.Core 1.5.374.126 via OpcUaServer)
- GHSA-37gx-xxp4-5rgx + GHSA-w3x6-4m5h-cxqf (legacy advisories already accepted)
OpcUaServer pins OPCFoundation.NetStandard.Opc.Ua.Configuration to 1.5.374.126
via VersionOverride to match Opc.Ua.Server's transitive Opc.Ua.Core (same
constraint as the legacy Server project).
Runtime does NOT project-reference any concrete Driver.* assemblies; drivers
load reflectively at runtime (Phase 6). Runtime gets the IDriver contract
through Core.Abstractions instead.
Host's Microsoft.Extensions.Hosting.WindowsServices is conditional on the
Windows OS so the project builds on macOS dev machines.
Build verification: dotnet build -> 438 warnings (all pre-existing xUnit1051
in legacy Server.Tests/Admin.Tests), 0 errors. Closes Task 9 (build green
smoke check, no separate commit).
