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.
- RestartDriver / ReconnectDriver messages + AdminOperationsActor
handlers (broadcast via driver-control DPS topic; audited via
ConfigEdits).
- DriverHostActor subscribes to driver-control; locates the
matching child DriverInstanceActor and stops+respawns it
(Restart) or sends it a ForceReconnect internal message
(Reconnect — re-enters Reconnecting state without full stop).
DriverInstanceSpec constructor call uses named args to handle
the full 6-parameter signature.
- New DriverOperator authorization policy mapped to DriverOperator
or FleetAdmin role; documented in docs/security.md. Map LDAP
group via GroupToRole (e.g. "ot-driver-operator": "DriverOperator").
- DriverStatusPanel renders Reconnect + Restart buttons when the
user holds the DriverOperator policy (hidden otherwise). Restart
requires an in-page Razor confirm block (no JS confirm, keeps
SignalR event loop unblocked). Both buttons show a spinner and
are disabled during in-flight; result chip auto-clears after 8s.
Username sourced from AuthenticationStateProvider.
Reconnect resolves to "ForceReconnect" (re-enter Reconnecting,
not full stop+respawn) — transport drops and retries while actor
and in-memory state are preserved. All DriverInstanceActor states
handle ForceReconnect safely (no-op when already in transition).
- AdminProbeService routes TestDriverConnect through
IAdminOperationsClient with a 65s outer guard (actor side already
clamps to [1,60]).
- Added generic AskAsync<T> to IAdminOperationsClient interface and
AdminOperationsClient impl, delegating straight to the Akka proxy.
- DriverTestConnectButton renders the button + inline result chip,
auto-clears after 30s, disables during in-flight.
- Wired into all 9 typed driver pages directly under the
identity section. Sources timeout from the form's
ProbeTimeoutSeconds; sources config JSON from the form's
current Options (operator can test BEFORE saving).
Cheap-and-fast probe: open TCP socket to the configured endpoint,
close immediately. Surfaces SocketError on failure, latency on
success, "timed out" on caller cancel. Sufficient for the AdminUI
Test Connect "can we reach the host?" question. Richer protocol-
level probes (OPC UA session open, FOCAS handshake, gRPC ping)
are a documented follow-up. Each probe registered as
AddSingleton<IDriverProbe, X> in DriverFactoryBootstrap so they
flow through DI into AdminOperationsActor.
Historian.Wonderware returns a clean "TCP probe not applicable"
result because it communicates over a Windows named pipe, not TCP.
Also adds OpcUaClient + Historian.Wonderware.Client project
references to Host.csproj (both were missing from the driver
ItemGroup).
- IDriverProbe abstraction in Core.Abstractions; one impl per driver
type, resolved by DriverType string. Phase 7.3 + 7.4 add concrete
probes for the 9 supported driver types.
- TestDriverConnect / TestDriverConnectResult messages.
- AdminOperationsActor.HandleTestDriverConnectAsync looks up the probe
by DriverType, runs it with a [1,60]s clamped timeout, and returns
success/latency or failure/message. Probes that throw or time out
surface as soft failures.
Live panel subscribed to the /hubs/driverstatus SignalR feed —
renders state chip, last-success age, 5-min error count, last
error message. Auto-reconnect; dimmed when no push arrives for 30s.
Hidden for new instances (nothing deployed yet); shown read-only
on every edit-mode page. Reconnect/Restart buttons land in Phase 8.
- IDriverHealthPublisher in Core.Abstractions + NullDriverHealthPublisher
no-op for tests/dev-stub paths.
- AkkaDriverHealthPublisher in Runtime forwards to the cluster-wide
`driver-health` DPS topic.
- DriverInstanceActor instrumented to publish snapshots on every
observable state change + a periodic 30s heartbeat so the AdminUI
snapshot store warms up for newly-joined SignalR clients.
- Sliding 5-minute Faulted-count tracked per actor via Queue<DateTime>.
- DriverHostActor.SpawnChild threads clusterId (_localNode.Value) and
the health publisher down to every DriverInstanceActor child.
- ServiceCollectionExtensions.AddOtOpcUaRuntime registers
AkkaDriverHealthPublisher as IDriverHealthPublisher singleton.
