Stratara.Infrastructure

Derived. The behaviour described here is specified under openspec/specs/. Those specifications are the source; this page explains and illustrates them.

License: MIT.

Cross-cutting infrastructure plumbing for the Stratara framework — the Tier-C glue that lets downstream apps wire authorization, DI composition, and worker-stack configuration with a single reference.

Contents

  • Authorization decorators over command-outbox dispatch (AuthorizingCommandOutboxDispatcher) — enforces [RequireRole] and [RequirePermission] on the command's runtime type before it reaches the outbox.
  • DI composition helpers that wire Mediator, Outbox, Identity, and EFCore into a hosted app.
  • Configuration providers and option binders used by the worker stack.

Dependencies

Transitively depends on Stratara.Contracts, Stratara.EventSourcing.EntityFrameworkCore, Stratara.Mediator, Stratara.Outbox.RabbitMQ, Stratara.Sessions, Stratara.Shared.

Behavioural notes

AddSecurity() — IKeyStore registration (since 3.0.11)

AddSecurity() registers Stratara's security stack including the IKeyStore abstraction. The default is a TryAddSingleton<IKeyStore, DummyKeyStore> fallback — but DummyKeyStore since 3.0.11 throws InvalidOperationException in any environment other than Development (whitelist guard to prevent production data exposure from the demo encryption key). Hosts on Staging, QA, UAT, Preview, or any custom environment must register a real IKeyStore implementation before calling AddSecurity():

// Recommended composition root
if (builder.Environment.IsDevelopment())
{
    builder.Services.AddSecurity();   // DummyKeyStore fallback is fine
}
else
{
    // The production key store Stratara ships (Stratara.Security): KEK-wrapped, versioned
    // per-scope DEKs. Register it before AddSecurity() so it wins the TryAdd race.
    builder.Services.AddStrataraFileKeyStore(builder.Configuration);
    builder.Services.AddSecurity();
}

Stratara ships one production IKeyStore — EnvelopeFileKeyStore, via AddStrataraFileKeyStore. There is no built-in Azure Key Vault / AWS KMS / HSM store; if you need one, implement IKeyStore against your provider and register it in place of the file store. Implement ListScopesAsync as well: an erasure asks the key store for every key naming the subject, and a store that cannot list leaves it with only the keys the directory names.

KeyStoreStartupProbe logs a Warning (event id LogEvents.KeyManagement.DummyKeyStoreActive = 112_001) at host start when the resolved IKeyStore is DummyKeyStore — even in Development — so an accidental dependency on the dummy is loud rather than silent.

Why the change: Before 3.0.11 the guard only blocked IsProduction(). Hosts in any other environment silently encrypted with the world-known constant pass-phrase "StrataraTestKey" baked into the shipping NuGet — a Staging or QA copy of production data could be decrypted by anyone reading the source. The whitelist guard makes this configuration crash-fast at host build instead of allowing silent data exposure.

AddCaching() — Redis registration

AddCaching() used to delegate to builder.AddRedisClient("redis") from Aspire.StackExchange.Redis. After the Aspire-wrapper removal it registers IConnectionMultiplexer directly via ConnectionMultiplexer.Connect(...) from StackExchange.Redis. The method signature is unchanged, but the Aspire-only side-effects are gone:

  • No automatic Redis health check. Add one explicitly with AddHealthChecks().AddRedis(connectionString) (from AspNetCore.HealthChecks.Redis) if your host exposes /health and you want Redis covered.
  • No automatic OpenTelemetry Redis instrumentation. Add OpenTelemetry.Instrumentation.StackExchangeRedis and .AddRedisInstrumentation() to your TracerProviderBuilder if you want Redis spans in your traces.

The connection-string lookup (ConnectionStrings:redis in configuration) is identical to the pre-cleanup behaviour.

Stratara.EventSourcing.WorkerDefaults

Worker-host wiring composites for the Stratara event-sourced stack. IHostApplicationBuilder extensions (AddBackendServices, AddCommandWorkerServices, AddHeavyCommandWorkerServices, AddEventProjectionWorkerServices, AddEventStreamHashWorkerServices, AddSagaWorkerServices, AddOutboxWorkerServices, and AddCommandServices, AddEventProjectionServices and AddSagaServices without the bus-fed workers) bundle the per-concern DI calls so each worker host opts in with one line.
Stratara.Testing.EntityFrameworkCore

Spin up the real Stratara event-sourcing write stack (EventSource, aggregation, snapshots, the EF Core write store) against a shared in-memory SQLite database in one call — production code paths, no Postgres, no Docker. Builds on Stratara.Testing's in-memory doubles.

A fix for hosts on the Orleans execution model. A host that removed or renamed a projection no longer has that
projection's store readers come back on every start and fail each entry; they retire once, as a saga's readers do. A
retired store reader now logs its retirement once instead of three times, and leaves no reminder error behind. No
API change, no schema change and no migration.

### Fixed

- **A reader of a removed projection retires.** On the Orleans execution model, a host that removed or renamed a
 projection kept the keep-alive reminders of its store readers. On every start of the silo they brought the readers
 back, and each one read the next entry of its partition, failed it because no projection of its name was
 registered, and tried again on the next tick, without end — a warning per partition and entry. Such a reader now
 retires the first time it is brought back, as a saga's reader already did: it unregisters its keep-alive, logs
 `117_136` `UnregisteredProjectionReaderRetired` (Information) once, reads nothing and deactivates. Its checkpoints
 stay, so a projection registered again resumes where it stopped; *Operate the Orleans execution model* says how to
 delete them. In a rolling deployment that adds a projection, a reader that lands on a silo of the earlier version
 refuses a rebuild's or a replay's pause, which then fails naming it, and a wait counts its partition as behind.
- **A retired store reader logs its retirement once.** A reader that retired as it was activated — of a partition
 beyond a lowered partition count, or of a saga the silo no longer registers — deactivated before it answered the
 call that activated it. Orleans forwarded that call to a new activation, which retired again, so the retirement was
 logged three times per reader and the keep-alive tick ended in `Could not deliver reminder tick` at Error. The
 reader now answers the call first and deactivates after it.
