Stratara.Sessions

License: FSL-1.1-MIT (Functional Source License — source-available; converts to MIT after 2 years). Not OSI-approved OSS.

Concrete session-context provider + ASP.NET Core middleware for Stratara's Actor/Subject session model. Reads tenant + user identity from JWT claims (with optional X-Tenant-Id / X-Client-Id header fallbacks), populates the ambient ISessionContextProvider, and exposes the Actor/Subject pair to every request.

Since 3.0.10: the X-Tenant-Id header fallback is opt-in via SessionContextOptions.AllowTenantHeader = true (default false). Without the gate, any authenticated principal could pick the tenant their request operated against in hosts whose JWT does not carry the tenant claim. Embed the tenant id in the JWT claim set, or opt in explicitly when an upstream platform-admin role check guards the header.

Quick start

// Program.cs / Startup.cs
builder.Services.AddSessionContext();

// In the middleware pipeline:
app.UseMiddleware<SessionContextMiddleware>();

Then resolve in any scoped service:

public sealed class SomeHandler(ISessionContextProvider sessionContextProvider)
{
    public async Task HandleAsync(...) {
        var session = sessionContextProvider.Current
            ?? throw new InvalidOperationException("Session context not set");

        // session.TenantId        = Subject (data owner) — used for filtering / encryption AAD
        // session.UserId          = Subject user (nullable)
        // session.ActorTenantId   = Actor (who triggered) — audit trail
        // session.ActorUserId     = Actor user — audit trail
    }
}

What's in the box

  • SessionContextProvider — internal sealed impl of ISessionContextProvider, scoped per request. Writes Activity tags (correlation.id, causation.id, tenant.id, user.id) automatically on Set / Clear.
  • SessionContextMiddleware — ASP.NET Core middleware that extracts tenant + user from ClaimTypes.NameIdentifier + stratara:tenant_id claim (with optional X-Tenant-Id header fallback gated by SessionContextOptions.AllowTenantHeader) and constructs a SessionContext with Actor=Subject (the default UserPlatform case).
  • SessionContextOptions — configuration (SessionContext section) controlling the header fallback gate. Bind via services.Configure<SessionContextOptions>(...) or services.AddOptions<SessionContextOptions>().Bind(...).
  • StrataraClaimTypes — claim-name constants (stratara:tenant_id).
  • DefaultTenantIdentifier — sentinel Guid used when no tenant claim or header is present (typically anonymous / system flows).
  • AddSessionContext() DI extension — registers the concrete provider as a scoped service against ISessionContextProvider.

Adopting the Actor/Subject model

For most operations Actor equals the data-owner Subject — a user acts on their own tenant's data. The split only diverges for:

  • PlatformAdmin cross-tenant operations (Subject = customer tenant, Actor = admin tenant)
  • Anonymous endpoints (Actor = Guid.Empty, Subject = the just-minted tenant)
  • System / saga flows (Actor = SessionContext.SystemActorTenantId / SystemActorUserId)

Consumers that reject ambient context (libraries that prefer explicit TenantId parameters everywhere) do not need to take this package — Stratara.Mediator and the rest of the framework work without an ISessionContextProvider registered as long as no path requires it.

Dependencies

  • Stratara.Abstractions — for ISessionContextProvider.
  • Stratara.Contracts — for the SessionContext record (wire-level).
  • Stratara.Diagnostics — for ApplicationDiagnostics activity tags.
  • Microsoft.AspNetCore.Http.Abstractions — for HttpContext / RequestDelegate.
  • Microsoft.Extensions.DependencyInjection.Abstractions.
  • OpenTelemetry.Api.

Stratara.Shared

Umbrella package for the Stratara framework — source-generated logger extensions for command flows, domain-event helpers, merge primitives, and the Tier-A/B abstractions surface re-exported as one transitive bundle.
Stratara.Outbox.RabbitMQ

Outbox-pattern command and event dispatch for the Stratara event-sourced stack — RabbitMQ IMessageBus implementation, retry worker, mediator command worker, and Redis-coordinated projection-replay state. Azure Service Bus support ships as the sibling Stratara.Outbox.AzureServiceBus package.
Stratara.Infrastructure

Infrastructure glue for the Stratara framework — authorization decorators, configuration providers, and DI composition helpers that wire Mediator, Outbox, Identity, and EF Core into a hosted app.

### Added

- **New package `Stratara.Testing`** — test doubles and assertion helpers so consumers can
 unit-test Stratara-based code without Postgres or RabbitMQ testcontainers. Reference it from
 test projects only.
 - `AggregateTestHarness<T>` + `Aggregate.Rehydrate<T>(...)` — given/when/then rehydration of an
   aggregate from events using the same reflection-based `Apply(...)` dispatch as the production
   aggregation service. It throws on an event with no matching `Apply` overload so a forgotten or
   mistyped overload fails the test; opt back into the production-lenient skip with
   `IgnoringUnmappedEvents()`.
 - `InMemoryKeyStore` — an `IKeyStore` that mints random 256-bit DEKs per `KeyScope` and supports
   rotation / revocation / scope-erasure without a master KEK or key file.
 - `TestBlobEncryptor.CreateAesGcm()` — the real AES-GCM `ISecureBlobEncryptor` over an
   `InMemoryKeyStore`, so blob round-trips exercise production encryption.
 - `InMemoryMessageBus` — an `IMessageBus` with synchronous in-process dispatch and a `Published`
   list for assertions.
 - `TestSessionContext` / `TestSessionContextProvider` — preset Actor/Subject `SessionContext`
   values and an `ISessionContextProvider` double.
 - `TestTenants.Of("acme")` — stable, deterministic tenant/user ids from readable slugs.
   `TestSessionContext` sets both correlation and causation ids so the context can drive
   event-store writes.
 - `TestEvent.Create(payload, ...)` — wrap an event payload in `IEvent<T>` with realistic
   metadata; `ProjectionTester.HandleAsync(projection, event)` — invoke a projection's private
   `HandleAsync` handler directly to unit-test it against mocked repositories.
- **New package `Stratara.Testing.EntityFrameworkCore`** — spins up the **real** event-sourcing
 write stack (`IEventSource`, `IAggregationService`, snapshots, the EF Core write store) against a
 shared in-memory SQLite database in one call, so tests exercise production code paths without
 Postgres or Docker. Reference it from test projects only.
 - `EventStoreTestHost.Create(...)` — owns the SQLite connection + service provider; exposes
   `ExecuteAsync(IEventSource)`, `AggregateAsync<T>(streamId)`, the preset `Session`, and the
   recording `Outbox`.
 - `AddStrataraTestingEventStore<TWriteDbContext>(connection, tenantId)` — the lower-level DI
   extension; `StrataraTestWriteDbContext` — a ready-made concrete write context;
   `RecordingEventBundleOutboxDispatcher` — captures emitted bundles for assertions.
 - The lockstep family grows from 22 to 24 packable packages.
