From bd41a12efdf156554c1ddf462c24c065e59342a8 Mon Sep 17 00:00:00 2001 From: Anto Subash Date: Mon, 11 May 2026 13:24:47 +0200 Subject: [PATCH 1/4] feat(events): durable inbox/outbox via Wolverine EF Core integration Replaces in-process Wolverine with durable messaging backed by the configured database (SQLite, PostgreSQL, or SQL Server). Adds: - WolverineFx.{Sqlite,Postgresql,SqlServer,EntityFrameworkCore} packages - IEvent now requires EventId + OccurredAt; new DomainEvent record base supplies both via Guid.CreateVersion7() / DateTimeOffset.UtcNow. All 25 event records migrated to inherit from DomainEvent - DomainEventInterceptor deleted; replaced by Wolverine's PublishDomainEventsFromEntityFrameworkCore(x => x.Events) - WolverineConfiguration.Configure() helper shared by web host and worker - Auto-discovery of every module assembly for handler scanning; per-module WolverineExtension shims removed - 9 service-level publishes migrated to atomic outbox via IDbContextOutbox.SaveChangesAndFlushMessagesAsync (Tenants: Update, ChangeStatus, AddHost, RemoveHost; Email templates: Update, Delete; SendEmailJob; RetryFailedEmailsJob) - FakeDbContextOutbox test helper for unit-testing outbox-using services - Test factory uses per-process temp SQLite file for Wolverine durability (in-memory SQLite is rejected by Wolverine.Sqlite) - CONSTITUTION.md documents the new guarantees and the small carve-out for publishes that stay on bus.PublishAsync (DB-generated IDs, UserManager, SettingsService DI cycle) - New tests: WolverineAssemblyDiscoveryTests, WolverineDurabilitySmokeTests, DomainEventScrapingTests; legacy DomainEventInterceptorTests removed --- .gitignore | 1 + Directory.Packages.props | 4 + docs/CONSTITUTION.md | 14 +- .../Entities/AuditableAggregateRoot.cs | 11 +- .../Entities/IHasDomainEvents.cs | 9 +- framework/SimpleModule.Core/Events/IEvent.cs | 25 +- .../Interceptors/DomainEventInterceptor.cs | 81 ------- .../SimpleModule.Database.csproj | 1 + .../Emitters/HostingExtensionsEmitter.cs | 3 + .../Emitters/ModuleExtensionsEmitter.cs | 17 ++ .../SimpleModule.Hosting.csproj | 4 + .../SimpleModuleHostExtensions.Helpers.cs | 4 +- .../SimpleModuleHostExtensions.cs | 24 +- .../SimpleModuleOptions.cs | 9 + .../SimpleModuleWorkerExtensions.cs | 52 ++-- .../WolverineConfiguration.cs | 57 +++++ .../AuditLogsWolverineExtension.cs | 16 -- .../Events/EmailFailedEvent.cs | 2 +- .../Events/EmailRetryAttemptEvent.cs | 2 +- .../Events/EmailSentEvent.cs | 2 +- .../Events/EmailTemplateCreatedEvent.cs | 2 +- .../Events/EmailTemplateDeletedEvent.cs | 2 +- .../Events/EmailTemplateUpdatedEvent.cs | 2 +- .../EmailService.Templates.cs | 13 +- .../src/SimpleModule.Email/EmailService.cs | 2 + .../Jobs/RetryFailedEmailsJob.cs | 13 +- .../SimpleModule.Email/Jobs/SendEmailJob.cs | 17 +- .../Unit/EmailServiceTests.cs | 4 + .../Events/FeatureFlagOverrideChangedEvent.cs | 2 +- .../Events/FeatureFlagToggledEvent.cs | 2 +- .../Events/FileDeletedEvent.cs | 2 +- .../Events/FileUploadedEvent.cs | 2 +- .../OpenIddictWolverineExtension.cs | 16 -- .../Events/SettingChangedEvent.cs | 2 +- .../Events/SettingDeletedEvent.cs | 2 +- .../Events/TenantCreatedEvent.cs | 2 +- .../Events/TenantHostAddedEvent.cs | 2 +- .../Events/TenantHostRemovedEvent.cs | 2 +- .../Events/TenantStatusChangedEvent.cs | 2 +- .../Events/TenantUpdatedEvent.cs | 2 +- .../src/SimpleModule.Tenants/TenantService.cs | 21 +- .../Unit/TenantServiceTests.cs | 21 +- .../Events/UserCreatedEvent.cs | 2 +- .../Events/UserDeletedEvent.cs | 2 +- .../Events/UserRolesChangedEvent.cs | 2 +- .../Events/UserSelfUnlockedEvent.cs | 2 +- .../Events/UserSignedOutEverywhereEvent.cs | 2 +- .../Events/UserUpdatedEvent.cs | 2 +- template/SimpleModule.Worker/Program.cs | 2 +- .../WebApplicationFactoryTests.cs | 2 +- .../DomainEventInterceptorTests.cs | 228 ------------------ .../DomainEventScrapingTests.cs | 154 ++++++++++++ .../SimpleModule.Database.Tests.csproj | 2 + .../WolverineAssemblyDiscoveryTests.cs | 49 ++++ .../WolverineDurabilitySmokeTests.cs | 169 +++++++++++++ .../Fakes/FakeDbContextOutbox.cs | 108 +++++++++ .../SimpleModuleWebApplicationFactory.cs | 36 +++ 57 files changed, 787 insertions(+), 448 deletions(-) delete mode 100644 framework/SimpleModule.Database/Interceptors/DomainEventInterceptor.cs create mode 100644 framework/SimpleModule.Hosting/WolverineConfiguration.cs delete mode 100644 modules/AuditLogs/src/SimpleModule.AuditLogs/AuditLogsWolverineExtension.cs delete mode 100644 modules/OpenIddict/src/SimpleModule.OpenIddict/OpenIddictWolverineExtension.cs delete mode 100644 tests/SimpleModule.Database.Tests/DomainEventInterceptorTests.cs create mode 100644 tests/SimpleModule.Database.Tests/DomainEventScrapingTests.cs create mode 100644 tests/SimpleModule.Database.Tests/WolverineAssemblyDiscoveryTests.cs create mode 100644 tests/SimpleModule.Database.Tests/WolverineDurabilitySmokeTests.cs create mode 100644 tests/SimpleModule.Tests.Shared/Fakes/FakeDbContextOutbox.cs diff --git a/.gitignore b/.gitignore index 663bb008..892dc204 100644 --- a/.gitignore +++ b/.gitignore @@ -443,3 +443,4 @@ template/SimpleModule.Host/storage/ # Temporary refactor baseline — not committed baseline/ +.claude/settings.local.json diff --git a/Directory.Packages.props b/Directory.Packages.props index 4e24d7e0..4a16ef67 100644 --- a/Directory.Packages.props +++ b/Directory.Packages.props @@ -65,6 +65,10 @@ + + + + diff --git a/docs/CONSTITUTION.md b/docs/CONSTITUTION.md index 69a89085..5321b7b2 100644 --- a/docs/CONSTITUTION.md +++ b/docs/CONSTITUTION.md @@ -195,11 +195,15 @@ This is cosmetic organization -- all modules share one connection. ### Events - Cross-module notifications use Wolverine's `IMessageBus.PublishAsync()` -- Events are records implementing the `IEvent` marker, defined in the publishing module's Contracts project -- Any module can handle any event by declaring a class with a `Handle` / `Consume` / `HandleAsync` method taking the event as its first parameter — Wolverine discovers handlers by naming convention -- In-process only: no external transports, no durable outbox, no cross-restart persistence.

Schema is auto-created on startup. +- Most service-level publishes are **atomic with the business write**: services inject `IDbContextOutbox`, stage entity changes, call `outbox.PublishAsync(...)`, and finish with `outbox.SaveChangesAndFlushMessagesAsync()` so the EF write and the outbox envelope commit in the same transaction. +- Events raised by `IHasDomainEvents` aggregates are scraped by Wolverine's `PublishDomainEventsFromEntityFrameworkCore(x => x.Events)` integration during the same transactional flush. +- Three categories remain on the durable-but-non-atomic `bus.PublishAsync` pattern (microsecond commit→publish gap, mitigated by inbox dedup): (1) **create events with DB-generated identifiers** — the new ID is not known until after `SaveChangesAsync` returns; switching the affected identifiers (`TenantId`, `FileStorageId`, `EmailMessageId`, `EmailTemplateId`) to caller-generated `Guid.CreateVersion7()` would close the gap; (2) **`UserService` / `UserAdminService` and the self-service account endpoints** — ASP.NET Identity's `UserManager` owns its `SaveChanges` and cannot be enrolled in the outbox; (3) **`SettingsService`** — switching it to `IDbContextOutbox` re-introduces the DI cycle the existing `Lazy` was added to break (resolve by moving the `AuditingMessageBus` settings gate to a Wolverine middleware). +- Handlers should be stateless, independent, and idempotent — the inbox dedup is a safety net, not a substitute for idempotency. +- Wolverine logs handler exceptions and discards the message on first failure by default (`MaximumAttempts = 1` on local queues). Non-critical handlers (audit, metrics, cache invalidation) should still catch their own exceptions where the failure mode would otherwise produce noisy log spam. ### When to Use Which Communication Pattern diff --git a/framework/SimpleModule.Core/Entities/AuditableAggregateRoot.cs b/framework/SimpleModule.Core/Entities/AuditableAggregateRoot.cs index 810b237e..0302e1e7 100644 --- a/framework/SimpleModule.Core/Entities/AuditableAggregateRoot.cs +++ b/framework/SimpleModule.Core/Entities/AuditableAggregateRoot.cs @@ -4,15 +4,12 @@ namespace SimpleModule.Core.Entities; /// /// Aggregate root with audit tracking, soft delete, versioning, and domain events. -/// Domain events are automatically dispatched via Wolverine's IMessageBus after SaveChanges. +/// Domain events added via are flushed to Wolverine's +/// durable outbox during SaveChangesAsync, atomic with the EF transaction. /// public abstract class AuditableAggregateRoot : FullAuditableEntity, IHasDomainEvents { - private readonly List _domainEvents = []; + public List Events { get; } = []; - public IReadOnlyList GetDomainEvents() => _domainEvents.AsReadOnly(); - - public void ClearDomainEvents() => _domainEvents.Clear(); - - protected void AddDomainEvent(IEvent domainEvent) => _domainEvents.Add(domainEvent); + protected void AddDomainEvent(IEvent domainEvent) => Events.Add(domainEvent); } diff --git a/framework/SimpleModule.Core/Entities/IHasDomainEvents.cs b/framework/SimpleModule.Core/Entities/IHasDomainEvents.cs index d77ad308..8ce61c9d 100644 --- a/framework/SimpleModule.Core/Entities/IHasDomainEvents.cs +++ b/framework/SimpleModule.Core/Entities/IHasDomainEvents.cs @@ -3,11 +3,12 @@ namespace SimpleModule.Core.Entities; /// -/// Entities implementing this interface can raise domain events that are automatically -/// dispatched via Wolverine's IMessageBus after a successful SaveChanges. +/// Entities implementing this interface have their list scraped +/// by Wolverine's PublishDomainEventsFromEntityFrameworkCore integration during +/// SaveChangesAsync — events are written to the outbox in the same transaction +/// as the EF business write, and the list is cleared after scrape. /// public interface IHasDomainEvents { - IReadOnlyList GetDomainEvents(); - void ClearDomainEvents(); + List Events { get; } } diff --git a/framework/SimpleModule.Core/Events/IEvent.cs b/framework/SimpleModule.Core/Events/IEvent.cs index 8467e613..3b8a6c79 100644 --- a/framework/SimpleModule.Core/Events/IEvent.cs +++ b/framework/SimpleModule.Core/Events/IEvent.cs @@ -1,5 +1,24 @@ namespace SimpleModule.Core.Events; -#pragma warning disable CA1040 // Avoid empty interfaces - marker interface by design -public interface IEvent; -#pragma warning restore CA1040 +/// +/// Marker contract for cross-module domain events.

Also fixes a real pre-existing bug surfaced by this verification: AuditConfigCacheInvalidator was never being discovered as a Wolverine handler because its class name didn't end in a recognized convention suffix (Handler/Consumer/Subscriber). Renamed to AuditConfigCacheInvalidatorHandler so default discovery picks it up and auditlogs.* setting changes now actually invalidate the request config cache as intended.

Wrap the publish in Wolverine.TrackActivity so the assertion only runs after the handler has actually executed. --- .../WolverineAssemblyDiscoveryTests.cs | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) diff --git a/tests/SimpleModule.Database.Tests/WolverineAssemblyDiscoveryTests.cs b/tests/SimpleModule.Database.Tests/WolverineAssemblyDiscoveryTests.cs index 498680f2..8709bfaa 100644 --- a/tests/SimpleModule.Database.Tests/WolverineAssemblyDiscoveryTests.cs +++ b/tests/SimpleModule.Database.Tests/WolverineAssemblyDiscoveryTests.cs @@ -2,6 +2,7 @@ using Microsoft.Extensions.Hosting; using SimpleModule.Core.Events; using Wolverine; +using Wolverine.Tracking; namespace SimpleModule.Database.Tests; @@ -29,7 +30,20 @@ public async Task Handler_In_Included_Assembly_Is_Invoked() await host.StartAsync(); var bus = host.Services.GetRequiredService(); - await bus.PublishAsync(new DiscoveryTestEvent("hello")); + + // Wait for the handler to actually execute before asserting — PublishAsync + // is fire-and-forget; on slower runners (Linux CI) the assertion otherwise + // races against the in-memory dispatcher. + await host.TrackActivity() + .Timeout(TimeSpan.FromSeconds(10)) + .ExecuteAndWaitAsync( + (Func)( + async _ => + { + await bus.PublishAsync(new DiscoveryTestEvent("hello")); + } + ) + ); DiscoveryTestHandler.LastPayload.Should().Be("hello");
