847302e297 test(dcl): add failover state machine tests for DataConnectionActor 2026-03-22 08:47:44 -04:00

46304678da feat(dcl): extend CreateConnectionCommand with backup config and failover retry count 
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.

5ec7f35150 feat(dcl): replace hand-rolled LmxProxy gRPC client with real LmxProxyClient library 
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.

7740a3bcf9 feat: add JoeAppEngine OPC UA nodes, fix DCL auto-reconnect and quality push 
- 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

e837eae2cc feat: wire real LmxProxy gRPC client into Data Connection Layer 
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.

75a6636a2c fix: wire DCL connection state changes into ISiteHealthCollector 
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.

389f5a0378 Phase 3B: Site I/O & Observability — Communication, DCL, Script/Alarm actors, Health, Event Logging 
Communication Layer (WP-1–5):
- 8 message patterns with correlation IDs, per-pattern timeouts
- Central/Site communication actors, transport heartbeat config
- Connection failure handling (no central buffering, debug streams killed)

Data Connection Layer (WP-6–14, WP-34):
- Connection actor with Become/Stash lifecycle (Connecting/Connected/Reconnecting)
- OPC UA + LmxProxy adapters behind IDataConnection
- Auto-reconnect, bad quality propagation, transparent re-subscribe
- Write-back, tag path resolution with retry, health reporting
- Protocol extensibility via DataConnectionFactory

Site Runtime (WP-15–25, WP-32–33):
- ScriptActor/ScriptExecutionActor (triggers, concurrent execution, blocking I/O dispatcher)
- AlarmActor/AlarmExecutionActor (ValueMatch/RangeViolation/RateOfChange, in-memory state)
- SharedScriptLibrary (inline execution), ScriptRuntimeContext (API)
- ScriptCompilationService (Roslyn, forbidden API enforcement, execution timeout)
- Recursion limit (default 10), call direction enforcement
- SiteStreamManager (per-subscriber bounded buffers, fire-and-forget)
- Debug view backend (snapshot + stream), concurrency serialization
- Local artifact storage (4 SQLite tables)

Health Monitoring (WP-26–28):
- SiteHealthCollector (thread-safe counters, connection state)
- HealthReportSender (30s interval, monotonic sequence numbers)
- CentralHealthAggregator (offline detection 60s, online recovery)

Site Event Logging (WP-29–31):
- SiteEventLogger (SQLite, 6 event categories, ISO 8601 UTC)
- EventLogPurgeService (30-day retention, 1GB cap)
- EventLogQueryService (filters, keyword search, keyset pagination)

541 tests pass, zero warnings.

34190e1347 Phase 0 WP-0.1: Create .NET 10 solution structure with all 17 component projects 
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.
