All external services (database, Discord/GitHub OAuth, S3) can now be individually disabled by omitting their environment variables. The server gracefully degrades functionality when services are unavailable. Partial configuration of any service group triggers a clear error at startup.
- Database: Falls back to dummy pool when DATABASE_URL is unset
- OAuth: Providers only registered when credentials are complete
- S3: Image storage disabled when credentials are missing
- Health checks reflect actual configuration state
- Add retry configuration for flaky tests (2 retries for default, 3 for
OAuth)
- Configure test groups with proper concurrency limits (serial: 1,
integration: 4)
- Add tower-http tracing layer with custom span formatting for HTTP
requests
- Simplify database pool handling by removing unnecessary Arc wrapper
- Improve test context setup with better logging and error handling
- Refactor user creation parameters for better clarity and consistency
- Add debug logging for OAuth cookie handling
