Resolve all 622 issues flagged by the enhanced CommentChecker: add missing
<returns> tags (incl. the standard phrasing on non-generic Task methods),
add missing <summary> tags, and replace misused/redundant <inheritdoc/> on
members that override or implement nothing with real documentation.
Documentation-only — no behavior change; solution builds clean.
The NativeAlarmActor sends SubscribeAlarmsRequest to the DCL manager, but the
manager only routed tag/write/browse messages to the per-connection
DataConnectionActor — alarm subscribe/unsubscribe were unhandled and dead-lettered,
so native alarms never subscribed at runtime. Caught by live T28 deployment.
Mirrors the existing HandleRoute forwarding.
Adds IAlarmSubscribableConnection to MxGatewayDataConnection (shared session-less
feed, ref-counted), IMxGatewayClient.RunAlarmStreamAsync over the package
StreamAlarmsAsync with internal reconnect, and MxGatewayAlarmMapper
(AlarmFeedMessage/OnAlarmTransitionEvent -> NativeAlarmTransition). Behavior
verified against a live gateway in Task 28; mapper unit-tested.
Adds IAlarmSubscribableConnection to OpcUaDataConnection, IOpcUaClient alarm
subscription methods, and RealOpcUaClient A&C event monitored-item +
EventFilter + ConditionRefresh snapshot, mapping fields via OpcUaAlarmMapper.
Behavior verified against a live A&C server in Task 28; mapper unit-tested.
Expanding a Galaxy object in the tag picker hung on "loading…": the browse
reply inlined every child's full attribute set (~152 KB), exceeding Akka's
128 KB remote frame, and remoting silently discarded the oversized reply.
Browse path (DataConnectionLayer):
- RealMxGatewayClient: navigation now uses BrowseChildren(include_attributes=
false) — child objects only — and an object's own attributes load lazily via
DiscoverHierarchy(root, max_depth=0) when it's expanded. Payload drops from
~152 KB/level to a few KB. Seam contract unchanged.
- DataConnectionActor.CapBrowseChildren: protocol-agnostic byte-budget cap
(~100 KB) on every BrowseNodeResult before it crosses the site→central
frame, OR-ing the adapter's own Truncated flag. Byte budget, not a count —
the only bound that holds regardless of NodeId/attribute-name length.
- RealOpcUaClient: requestedMaxReferencesPerNode 1000 → 500 to narrow the
window before the byte budget applies.
- Graceful gRPC Unimplemented handling → NotSupportedException →
BrowseFailureKind.NotBrowsable with an actionable message (older gateway
builds lacking BrowseChildren).
Picker UI (CentralUI):
- NodeBrowserDialog: modal-lg → modal-xl; new scoped .razor.css caps the tree
at 55vh with its own scrollbar so manual entry + Select/Cancel stay visible.
- Protocol-agnostic failure messages (was hardcoded "OPC UA …"); renamed the
leftover opcua-browser-tree class to node-browser-tree.
Tests: new frame-budget cap test + NotSupported=>NotBrowsable mapping test;
DCL suite 88/88. Doc: Component-DataConnectionLayer.md records the lazy
attribute-light browse and the frame-size guard.
DataConnectionFactory registers 'MxGateway' -> MxGatewayDataConnection over the
real client; AddDataConnectionLayer binds MxGatewayGlobalOptions; DeploymentManager
FlattenConnectionConfig gains an MxGateway arm using the typed serializer. Factory
test confirms Create("MxGateway") returns the adapter.
Seam implementation wrapping the gateway client + GalaxyRepositoryClient:
OpenSession/Register, AddItem+Advise subscribe, ReadBulk/WriteBulk with handle
tracking, StreamEvents loop with worker_sequence resume + OPC-style quality
mapping, and Galaxy BrowseChildren mapping (objects keyed by gobject id,
attributes by full tag reference). Only type touching the generated contracts.
Implements IDataConnection + IBrowsableDataConnection over the IMxGatewayClient
seam: connect/disconnect with once-only Disconnected guard + background event
loop, subscribe/unsubscribe with tag routing, read/write batch with per-tag
error classification, WriteBatchAndWait, and Galaxy browse mapping. Covers plan
Tasks 6-10. Full unit coverage via FakeMxGatewayClient (12 tests).
Central package management requires package-source mapping with >1 feed
(NU1507 as error), so nuget.config scopes ZB.MOM.WW.MxGateway.* to the Gitea
feed and everything else to nuget.org. Credentials are not committed.
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.
- BrowseOpcUaNodeCommand: int DataConnectionId -> string ConnectionName
(site DataConnectionManagerActor indexes children by name; CentralUI
already has the connection name in scope via the dropdown — no extra
plumbing across the trust boundary).
- IOpcUaBrowseService / OpcUaBrowseService: parameter renamed accordingly.
- OpcUaBrowserDialog: collapse the duplicate ConnectionName parameters
(display label and routing key are the same string).
- Task 10: DataConnectionManagerActor forwards BrowseOpcUaNodeCommand to
its child by name (owns ConnectionNotFound); DataConnectionActor adds
the receive across all three lifecycle states (Connecting / Connected
/ Reconnecting) and maps adapter outcomes to BrowseFailureKind
(NotBrowsable / ConnectionNotConnected / Timeout / ServerError).
- Task 17: SetFailure in OpcUaBrowserDialog implements the full
BrowseFailureKind switch with friendly UI messages.
- Tests: DataConnectionManagerBrowseHandlerTests covers ConnectionNotFound,
NotBrowsable, success, and ConnectionNotConnectedException paths.
