- Add DebugStreamBridgeActorTests: On_InstanceNotFound_Snapshot_Forwards_To_OnEvent_Does_Not_Open_Stream_And_Terminates — asserts _onEvent receives the not-found snapshot, SubscribeCalls remains empty, and the actor terminates cleanly via Watch/ExpectTerminated.
- Add comment in DebugStreamBridgeActor near Context.Stop(Self) explaining that the subsequent StopDebugStream Tell from DebugStreamService.StopStream produces a benign expected dead-letter.
- Reword not-found toast in DebugView.razor to "Instance not found on the selected site — check the deployment target." (accurate when the instance may be deployed to a different site).
RouteDebugSnapshot and RouteDebugViewSubscribe on DeploymentManagerActor
previously returned an empty DebugViewSnapshot for unknown instances,
indistinguishable from a deployed-but-empty instance. Callers had no way
to differentiate "not deployed here" from "deployed, no data yet."
Approach — additive field on existing message contract:
Added `bool InstanceNotFound = false` as an optional trailing parameter
to DebugViewSnapshot (Commons). All existing positional constructor calls
and serialized wire frames are unaffected (default = false). A dedicated
new message type was considered but rejected: the ClusterClient channel
and DebugStreamService TCS are already typed on DebugViewSnapshot, and a
second reply union would require wider changes for zero additive-safety
gain.
Changes:
- Commons/DebugViewSnapshot: add InstanceNotFound = false (additive)
- DeploymentManagerActor: set InstanceNotFound=true in both unknown-
instance branches (RouteDebugViewSubscribe, RouteDebugSnapshot)
- DebugStreamBridgeActor: when snapshot.InstanceNotFound, forward it to
_onEvent (resolves the TCS) then stop cleanly; no gRPC stream opened
- DebugView.razor: check session.InitialSnapshot.InstanceNotFound after
connect and show a clear "not deployed on this site" error toast
- 3 new tests in DeploymentManagerActorTests covering: unknown→snapshot,
unknown→subscribe, known-empty→InstanceNotFound stays false
Adds a Test Bindings button to the Connection Bindings table on the Configure
Instance page that opens a modal showing the live current value of every bound
attribute. Reuses the routing path that the OPC UA tag browser landed on:
Central: TestBindingsDialog → IBindingTester → CommunicationService
→ ReadTagValuesCommand → SiteEnvelope (Ask)
Site: SiteCommunicationActor → DeploymentManagerActor singleton
→ DataConnectionManagerActor → child DataConnectionActor
→ _adapter.ReadBatchAsync
Split mirrors the browse handler:
• Manager owns ConnectionNotFound (only it sees the per-site connection set).
• Child owns ConnectionNotConnected (pre-call status check, never stash —
read is interactive design-time), Timeout (OperationCanceledException),
ServerError (any other exception). Per-tag failures from ReadBatchAsync
become failure TagReadOutcomes without aborting the batch.
CentralUI:
• IBindingTester / BindingTester — Design-role guard via HasClaim against
JwtTokenService.RoleClaimType (not IsInRole — see c1e16cf), typed
transport-failure translation.
• TestBindingsDialog — ShowAsync(siteId, rows, instanceLabel) method-arg
pattern (no Razor parameter race; see 2c138b6), groups rows by connection
and issues one ReadAsync per connection in parallel, per-row error subline
+ per-connection banner, Refresh button re-issues the reads.
• InstanceConfigure.razor — Test Bindings button next to Save Bindings,
disabled when no testable rows. OPC UA only today (other protocols have
no ReadTagValuesCommand wiring yet).
Tests:
• Commons: ReadTagValuesCommand discovered by ManagementCommandRegistry.
• DataConnectionLayer: unknown connection → ConnectionNotFound,
not-connected adapter → ConnectionNotConnected (ReadBatchAsync NOT called),
success-path mapping (Good/Bad + per-tag error), cancellation → Timeout.
• CentralUI: register IBindingTester (and the previously-missing
IOpcUaBrowseService) on the existing InstanceConfigureAuditDrillinTests
Bunit container so the page renders cleanly with the new dialog.
Wires the OPC UA Tag Browser cross-cluster path: central UI Asks via
CommunicationService.BrowseOpcUaNodeAsync -> ClusterClient -> site
SiteCommunicationActor -> /user/dcl-manager (Task 10 handler).
Uses ActorSelection.Tell(msg, Sender) since DataConnectionManagerActor
is not a child of DeploymentManagerActor and ActorSelection has no
Forward() helper; preserving Sender keeps the BrowseOpcUaNodeResult
routing back to the original Ask.
Integration test deferred: tests/ZB.MOM.WW.ScadaBridge.IntegrationTests
has no ClusterFixture (only ScadaBridgeWebApplicationFactory, which
does not expose a Communication service nor a seeded site OPC UA
connection). Round-trip will be exercised manually under Task 19.
