Both bugs surfaced only on split-role deployments (the MAIN cluster's
admin-only nodes), where the AdminUI runs without the driver role.
- Test Connect returned "No probe registered" for every driver: the
IDriverProbe set was registered only under the driver role, but the
admin-operations singleton that consumes it is pinned to admin. Extract
AddOtOpcUaDriverProbes() (idempotent via TryAddEnumerable) and call it
in the hasAdmin path too.
- Live driver-status/alerts/script-log panels showed "SignalR error:
Connection refused": these Blazor Server components opened a HubConnection
to their own hub via the browser's public URL, which server-side code
can't reach behind Traefik (host :9200 -> container :9000). Read the
in-process source directly instead -- DriverStatus via
IDriverStatusSnapshotStore.SnapshotChanged, Alerts/ScriptLog via a new
IInProcessBroadcaster<T>. Fleet status was unaffected (reads DB/ActorSystem).
Adds unit tests for probe registration, the snapshot-store event, and the
broadcaster.
GalaxyDriverPage deserialized DriverConfig with case-sensitive camelCase opts, but the
persisted/seeded config is PascalCase (the runtime reads it case-insensitively). So all four
nested option records read as null -> FromRecord NRE (HTTP 500) on edit, and the form would
have shown defaults instead of the real config (risking a clobber on save). Fix: add
PropertyNameCaseInsensitive=true (matches the runtime) so real values load, plus null-coalesce
the nested records in FromRecord as defense-in-depth. Regression test asserts the seeded
PascalCase config loads its real values.
The driver/factory/seed use 'GalaxyMxGateway' (legacy 'Galaxy' was retired),
but the AdminUI editor router, GalaxyDriverPage, address picker, identity
dropdown, the Galaxy browser/probe, and DraftValidator still keyed on 'Galaxy'.
Result: the seeded GalaxyMxGateway driver couldn't be edited ('no editor
registered'), UI-created Galaxy drivers wrote a type with no factory, and a
SystemPlatform-bound GalaxyMxGateway driver failed publish validation.
Align all stragglers to GalaxyMxGateway (+ failing-test-first DraftValidator
coverage). ShouldStub's 'Galaxy' legacy safety-net left intact.
Capture the original ModbusTagDefinition as _source in ModbusTagRow and
rewrite ToDefinition() to use 'with {}', so StringByteOrder, ArrayCount,
Deadband, UnitId, and CoalesceProhibited survive a load→edit→save cycle.
Single Cookie auth scheme; framework default challenge restores 302 → /login
for browsers + 401 for AJAX. OtOpcUaCookieOptions now flows through to
CookieAuthenticationOptions via PostConfigure (fixes a latent bug where the
options class was bound but ignored). Cookie name moves to
ZB.MOM.WW.OtOpcUa.Auth; existing sessions get a one-time forced sign-out.
DriverStatusPanel previously cached the username in a field at
OnInitializedAsync and forwarded the cached value into RestartDriver
/ ReconnectDriver messages. A token refresh or claim change mid-
circuit would land the stale name in the audit ConfigEdit row.
Re-reads AuthenticationStateProvider at button-click time so the
audit entry reflects the current principal.
- Topic-name drift fix: DriverHealthChanged.TopicName and
DriverControlTopic.Name now live on the message contracts in
Commons. AkkaDriverHealthPublisher, DriverStatusSignalRBridge,
DriverHostActor, and AdminOperationsActor all delegate to the
single constant so a rename can't silently desynchronise
publisher and subscriber.
- DriverStatusPanel._opResultClearTimer switched from
System.Timers.Timer to System.Threading.Timer + awaited
DisposeAsync. Prevents an in-flight 8s clear-callback from
invoking StateHasChanged on a component whose hub has already
been released.
- PublishHealthSnapshot deduplicates against the last published
(state, lastSuccess, lastError, errorCount) fingerprint. The
30s heartbeat no longer floods the SignalR layer with identical
Healthy snapshots — newly-joined clients still warm up via the
snapshot store on JoinDriver.
- DriverInstanceSpec carries ClusterId from the deployment artifact;
DriverHostActor threads the real cluster identity into
DriverInstanceActor instead of the local NodeId. Old pre-PR
artifacts without a ClusterId field fall back to the NodeId so
in-flight deployments keep working.
- DriverHostActor.ChildEntry holds the full DriverInstanceSpec
(was only carrying DriverType + LastConfigJson). Restart respawns
preserve RowId, Name, Enabled, ClusterId — no placeholder values.
- Drop the unnecessary _faultLock on DriverInstanceActor — every
read/write site runs inside an Akka message handler which is
single-threaded per actor instance.
- DriverStatusPanel.DisposeAsync awaits Timer.DisposeAsync so an
in-flight 5s tick can't invoke StateHasChanged on a component
whose hub has already been torn down.
- DriverTagPicker shell: modal chrome + per-driver picker body
rendered as ChildContent.
- 9 picker bodies (Modbus/AbCip/AbLegacy/S7/TwinCat/FOCAS/
OpcUaClient/Galaxy/Historian.Wonderware). 5 have computed
builder logic + unit tests; 4 are free-text passthroughs
(live browse for OPC UA + Galaxy is a documented follow-up).
- Each typed driver page gets a "Pick address" button that opens
the modal with the matching body. Picked address surfaces in
the modal footer for manual copy — no JS interop in v1.
