Add ActiveEndpoint field to DataConnectionHealthReport showing which
endpoint is active (Primary, Backup, or Primary with no backup configured).
Log failover transitions and connection restoration events to the site
event log via ISiteEventLogger, passed as an optional parameter through
the actor hierarchy for backwards compatibility.
Update CreateConnectionCommand to carry PrimaryConnectionDetails,
BackupConnectionDetails, and FailoverRetryCount. Update all callers:
DataConnectionManagerActor, DataConnectionActor, DeploymentManagerActor,
FlatteningService, and ConnectionConfig. The actor stores both configs
but continues using primary only — failover logic comes in Task 3.
Switches from v1 string-based proto stubs to the production LmxProxyClient
(v2 native TypedValue protocol) via project reference. Deletes 6k+ lines of
generated proto code. Preserves ILmxProxyClient adapter interface for testability.
Replace the CLI's Akka.NET ClusterClient transport with a simple HTTP client
targeting a new POST /management endpoint on the Central Host. The endpoint
handles Basic Auth, LDAP authentication, role resolution, and ManagementActor
dispatch in a single round-trip — eliminating the CLI's Akka, LDAP, and
Security dependencies.
Also fixes DCL ReSubscribeAll losing subscriptions on repeated reconnect by
deriving the tag list from _subscriptionsByInstance instead of _subscriptionIds.
- Add JoeAppEngine folder to OPC UA nodes.json (BTCS, AlarmCntsBySeverity, Scheduler/ScanTime)
- Fix DataConnectionActor: capture Self in PreStart for use from non-actor threads,
preventing Self.Tell failure in Disconnected event handler
- Implement InstanceActor.HandleConnectionQualityChanged to mark attributes Bad on disconnect
- Fix LmxFakeProxy TagMapper to serialize arrays as JSON instead of "System.Int32[]"
- Allow DataType and DataSourceReference updates in TemplateService.UpdateAttributeAsync
- Update test_infra_opcua.md with JoeAppEngine documentation
Replace stub ILmxProxyClient with production proto-generated gRPC client
(RealLmxProxyClient) that connects to LmxProxy servers with x-api-key
metadata header authentication. Includes pre-generated proto stubs for
ARM64 Docker compatibility, updated adapter with proper quality mapping
(Good/Uncertain/Bad), subscription via server-streaming RPC, and 20 unit
tests covering all operations. Updated Component-DataConnectionLayer.md
to reflect the actual implementation.
Three runtime bugs fixed:
- DataConnectionActor: TagValueReceived/TagResolutionSucceeded/Failed not
handled in any Become state — OPC UA values went to dead letters. Added
initial read after subscribe to seed current values immediately.
- AlarmActor: ParseEvalConfig expected "attributeName"/"matchValue"/"min"/
"max" keys but seed data uses "attribute"/"value"/"high"/"low". Added
support for both conventions and !=prefix for not-equal matching.
- InstanceActor: snapshots reported all alarms (including unevaluated) with
correct priorities and source timestamps instead of current UTC. Removed
bogus Vibration template attribute that shadowed Speed's tag mapping.
DataConnectionActor now calls UpdateConnectionHealth() on state
transitions (Connecting/Connected/Reconnecting) and UpdateTagResolution()
on connection establishment. DataConnectionManagerActor calls
RemoveConnection() on actor removal. Health reports now include
data connection statuses when instances are deployed with bindings.
- DataConnectionActor now stores and passes connection details to adapter ConnectAsync
- DataConnectionManagerActor passes connection details when creating actor
- RealOpcUaClient uses DiscoveryClient for endpoint selection with no-security preference
- Added certificate trust store paths to prevent TrustedIssuerCertificates error
- Sanitize connection names for Akka actor paths (replace spaces)
- Add connection binding UI to Instances page (per-attribute and bulk assign)
- FlatteningService populates Connections dict from bound data connections
- Real OPC UA client using OPC Foundation SDK for live tag subscriptions
- DataConnectionFactory uses RealOpcUaClientFactory by default
- OpcUaDataConnection supports both "endpoint" and "EndpointUrl" config keys
- Add TagValueUpdate/ConnectionQualityChanged handlers to InstanceActor
- InstanceActor subscribes to DCL on PreStart based on DataSourceReference
- DeploymentManagerActor creates DCL connections on deploy and passes DCL ref
- AkkaHostedService creates DCL Manager Actor for tag subscriptions
- Move CreateConnectionCommand to Commons for cross-project access
- Add ConnectionConfig to FlattenedConfiguration for deployment packaging
- WP-0.10: Role-based Host startup (Central=WebApplication, Site=generic Host),
15 component AddXxx() extension methods, MapCentralUI/MapInboundAPI stubs
- WP-0.11: 12 per-component options classes with config binding
- WP-0.12: Sample appsettings for central and site topologies
- Add execution procedure and checklist template to generate_plans.md
- Add phase-0-checklist.md for execution tracking
- Resolve all 21 open questions from plan generation
- Update IDataConnection with batch ops and IAsyncDisposable
57 tests pass, zero warnings.
17 source projects (Commons + Host + 15 components) and 17 xUnit test projects.
SLNX format, net10.0, nullable enabled, warnings as errors. All components
reference Commons; Host references all components. Builds and tests clean.
