Adds a real-infra mode for the integration test harness alongside the default
in-memory mode. Drops the previously-untested code paths (EF SqlServer
behaviors, real LDAP bind) under env-var control without breaking the
zero-infra default that CI runs.
- docker-compose.yml — minimal SQL 2022 (14331) + OpenLDAP (3894) stack
(ports chosen to coexist with docker-dev/ on 14330/3893)
- HarnessMode record reads OTOPCUA_HARNESS_USE_SQL=1 / USE_LDAP=1 from env
- SQL mode: per-harness unique DB OtOpcUa_Harness_{guid}, EnsureCreated
at startup, EnsureDeleted on dispose (best-effort)
- LDAP mode: drops StubLdapAuthService and configures real LdapAuthService
against the compose'd OpenLDAP via Authentication:Ldap:* config keys
- Microsoft.EntityFrameworkCore.SqlServer added to the test project
- README documents both modes + the macOS no-Docker caveat
Default in-memory mode unchanged — all 9 existing tests still pass.
Builds TwoNodeClusterHarness: two in-process Host-equivalent nodes sharing
an in-memory ConfigDb. Forms a 2-member Akka cluster. ClusterFormationTests
proves both nodes see each other as admin+driver role members.
Fixes a real production bug uncovered while wiring the harness — Program.cs
ran two separate ActorSystems (one from AddOtOpcUaCluster.AkkaHostedService
with cluster HOCON, one from Akka.Hosting.AddAkka with bare HOCON). Cluster
singletons landed on the bare ActorSystem and could not actually form a
cluster ("Configuration does not contain `akka.cluster` node").
Consolidation:
- AddOtOpcUaCluster now only binds AkkaClusterOptions + registers IClusterRoleInfo
- New WithOtOpcUaClusterBootstrap pushes embedded HOCON + Remote/Cluster options
into Akka.Hosting's AkkaConfigurationBuilder
- AkkaHostedService.cs deleted — Akka.Hosting now owns the lifecycle
- Program.cs + harness call WithOtOpcUaClusterBootstrap inside AddAkka
Why not WebApplicationFactory<Program>? Program.cs reads OTOPCUA_ROLES from
process env (shared across in-process WAFs); the harness replays Program.cs's
DI graph from a clean WebApplicationBuilder per node with per-node config
overrides. Same production extensions, isolated config + Kestrel + Akka ports.
Tests: 93 v2 tests pass (was 91 + 2 new cluster formation), 0 skipped.
