- Use defer func() with explicit error assignment to satisfy linter
- Remove unused connectToService function
- Function is not currently used (proto files not yet generated)
- Commented out with TODO for future implementation
- Prevents unused function lint error
Refactor core kernel and infrastructure to support true microservices
architecture where services are independently deployable.
Phase 1: Core Kernel Cleanup
- Remove database provider from CoreModule (services create their own)
- Update ProvideHealthRegistry to not depend on database
- Add schema support to database client (NewClientWithSchema)
- Update main entry point to remove database dependency
- Core kernel now provides only: config, logger, error bus, health, metrics, tracer, service registry
Phase 2: Service Registry Implementation
- Create ServiceRegistry interface (pkg/registry/registry.go)
- Implement Consul registry (internal/registry/consul/consul.go)
- Add Consul dependency (github.com/hashicorp/consul/api)
- Add registry configuration to config/default.yaml
- Add ProvideServiceRegistry() to DI container
Phase 3: Service Client Interfaces
- Create service client interfaces:
- pkg/services/auth.go - AuthServiceClient
- pkg/services/identity.go - IdentityServiceClient
- pkg/services/authz.go - AuthzServiceClient
- pkg/services/audit.go - AuditServiceClient
- Create ServiceClientFactory (internal/client/factory.go)
- Create stub gRPC client implementations (internal/client/grpc/)
- Add ProvideServiceClientFactory() to DI container
Phase 4: gRPC Service Definitions
- Create proto files for all core services:
- api/proto/auth.proto
- api/proto/identity.proto
- api/proto/authz.proto
- api/proto/audit.proto
- Add generate-proto target to Makefile
Phase 5: API Gateway Implementation
- Create API Gateway service entry point (cmd/api-gateway/main.go)
- Create Gateway implementation (services/gateway/gateway.go)
- Add gateway configuration to config/default.yaml
- Gateway registers with Consul and routes requests to backend services
All code compiles successfully. Core services (Auth, Identity, Authz, Audit)
will be implemented in Epic 2 using these foundations.
The Gin framework uses a global mode setting (gin.SetMode()) which is not
thread-safe when tests run in parallel. Removing t.Parallel() from metrics
tests that use gin.SetMode() prevents data races when running tests with
the race detector enabled.
All tests now pass with 'make test' which includes -race flag.
- Use typed context key instead of string in errorbus test to avoid collisions
- Remove unused imports (health.HealthChecker, trace.TracerProvider) from test files
- Simplify interface verification checks (removed unnecessary type assertions)
All linting errors resolved. make lint now passes.
The mockLogger's errors slice was being accessed concurrently from
multiple goroutines (the error bus consumer and the test goroutine),
causing race conditions when running tests with the race detector.
Added sync.Mutex to protect the errors slice and proper locking when
accessing it in test assertions.
The Gin framework uses a global mode setting (gin.SetMode()) which is not
thread-safe when tests run in parallel. Removing t.Parallel() from all
server tests that use gin.SetMode() prevents data races when running
tests with the race detector enabled.
All tests now pass with 'make test' which includes -race flag.

- Test OTLP exporter configuration
- Test graceful shutdown
- Test no-op tracer provider
All tests follow Go testing best practices:
- Table-driven tests where appropriate
- Parallel execution
- Proper mocking of interfaces
- Skip tests requiring external dependencies in short mode
- Fix error return value checks (errcheck)
- Fix unused parameters by using underscore prefix
- Add missing package comments to all packages
- Fix context key type issue in middleware (use typed contextKey)
- Replace deprecated trace.NewNoopTracerProvider with noop.NewTracerProvider
- Fix embedded field selector in database client
- Remove trailing whitespace
- Remove revive linter (as requested) to avoid stuttering warnings for public API interfaces
All linting and formatting checks now pass.
- Add fx.Invoke in main.go to force database and HTTP server creation
- This ensures all providers execute and their lifecycle hooks are registered
- Clean up debug logging statements
- Database migrations and HTTP server now start correctly on application startup
Fixes issue where database migrations and HTTP server were not starting
because FX providers were not being executed (lazy evaluation).
- Added logging when HTTP server OnStart hook is called
- Added error logging for database migration failures
- This will help identify if hooks are being called and where failures occur
- Added better error detection for HTTP server startup
- Added connectivity check to verify server is actually listening
- Increased wait time to 500ms for better error detection
- Added warning log if server connectivity check fails (may still be starting)
- Improved logging messages for server startup
This should help diagnose why the HTTP server isn't starting and provide better visibility into the startup process.
Fixes:
- Added database connection logging with masked DSN
- Added migration progress logging
- Added HTTP server startup logging with address
- Fixed database provider to accept logger parameter
- Improved error visibility throughout initialization
