U2 (Critical): RoslynVirtualTagEvaluator ran scripts with a CancellationToken that a synchronous Roslyn script can never observe, so one CPU-bound/infinite- loop virtual-tag script hung the owning VirtualTagActor forever (no timeout, no recovery). Route evaluation through the existing TimedScriptEvaluator (Task.Run + WaitAsync) so the wall-clock budget is real; a runaway script now returns Bad within the timeout instead of wedging the actor. U3 (High): the live path cached evaluators in a raw ConcurrentDictionary never cleared on republish, leaking a collectible AssemblyLoadContext per edited script forever. Swap in the purpose-built CompiledScriptCache (Lazy single- compile, dispose-on-Clear) and add an apply-boundary clear: a new narrow IScriptCacheOwner seam the VirtualTagHostActor calls on each ApplyVirtualTags generation (mirrors ScriptedAlarmEngine's per-generation clear). Tests: infinite-loop-fails-within-timeout (bounded by WaitAsync so a regression fails instead of hanging), happy-path-after-wrapping, ClearCompiledScripts- empties-cache, and a host-actor wiring guard asserting each apply generation calls ClearCompiledScripts (theme #1 production-caller assertion). Host.Integration VT suite 18/18, Runtime VT suite 12/12.
ZB.MOM.WW.OtOpcUa.Host.IntegrationTests
Two-node Akka cluster integration tests on top of TwoNodeClusterHarness.
Default mode (no infra required)
dotnet test tests/Server/ZB.MOM.WW.OtOpcUa.Host.IntegrationTests
Uses Microsoft.EntityFrameworkCore.InMemory for ConfigDb and a stub ILdapAuthService that
accepts any username when the password is valid-password. Each harness instance creates a
unique in-memory database scoped to its lifetime. This is the mode CI runs by default.
Real-infra mode (SQL Server + OpenLDAP)
When you need to exercise EF behaviors that diverge between providers (index uniqueness,
RowVersion concurrency, JSON columns, migration application) or a real LDAP bind, bring up
the bundled compose stack and set the env-var switches:
docker compose -f tests/Server/ZB.MOM.WW.OtOpcUa.Host.IntegrationTests/docker-compose.yml up -d
export OTOPCUA_HARNESS_USE_SQL=1
export OTOPCUA_HARNESS_USE_LDAP=1
dotnet test tests/Server/ZB.MOM.WW.OtOpcUa.Host.IntegrationTests
docker compose -f tests/Server/ZB.MOM.WW.OtOpcUa.Host.IntegrationTests/docker-compose.yml down -v
SQL Server mode (OTOPCUA_HARNESS_USE_SQL=1)
- Container:
mcr.microsoft.com/mssql/server:2022-latestonlocalhost:14331 - Each
TwoNodeClusterHarness.StartAsync()creates a unique databaseOtOpcUa_Harness_{guid}viaDatabase.EnsureCreatedAsync()and drops it onDisposeAsync()(best-effort). - Port
14331chosen to avoid colliding with thedocker-dev/fleet (which uses14330).
LDAP mode (OTOPCUA_HARNESS_USE_LDAP=1)
- Container:
bitnami/openldap:2.6onlocalhost:3894 - Users
alice/alice123andbob/bob123, all underou=FleetAdmin. - Port
3894chosen to avoid colliding with thedocker-dev/fleet (which uses3893).
Local-dev caveat
This dev VM (DESKTOP-6JL3KKO) does not run Docker locally. Real-infra mode runs on the
shared Linux Docker host (10.100.0.35) per docs/v2/dev-environment.md, or in CI on Linux.
