Unifies the two previously independent email subsystems — MailService
(net/smtp transport) and NotificationService (HTTP-based providers) —
so email can participate in the notification dispatch pipeline.
Key changes:
- SendEmail signature updated to accept context.Context and []string
recipients to enable timeout propagation and multi-recipient dispatch
- NotificationService.dispatchEmail() wires MailService as a first-class
provider type with IsConfigured() guard and 30s context timeout
- 'email' added to isSupportedNotificationProviderType() and
supportsJSONTemplates() returns false for email (plain/HTML only)
- settings_handler.go test-email endpoint updated to new SendEmail API
- Frontend: 'email' added to provider type union in notifications.ts,
Notifications.tsx shows recipient field and hides URL/token fields for
email providers
- All existing tests updated to match new SendEmail signature
- New tests added covering dispatchEmail paths, IsConfigured guards,
recipient validation, and context timeout behaviour
Also fixes confirmed false-positive CodeQL go/email-injection alerts:
- smtp.SendMail, sendSSL w.Write, and sendSTARTTLS w.Write sites now
carry inline codeql[go/email-injection] annotations as required by the
CodeQL same-line suppression spec; preceding-line annotations silently
no-op in current CodeQL versions
- auth_handler.go c.SetCookie annotated for intentional Secure=false on
local non-HTTPS loopback (go/cookie-secure-not-set warning only)
Closes part of #800
- Enhanced Notifications component tests to include support for Discord, Gotify, and Webhook provider types.
- Updated test cases to validate the correct handling of provider type options and ensure proper payload structure during creation, preview, and testing.
- Introduced new tests for Gotify token handling and ensured sensitive information is not exposed in the UI.
- Refactored existing tests for clarity and maintainability, including improved assertions and error handling.
- Added comprehensive coverage for payload validation scenarios, including malformed requests and security checks against SSRF and oversized payloads.
- Implement tests for feature flags coverage in `feature_flags_coverage_v2_test.go` to validate behavior with invalid persisted and environment values, as well as default settings.
- Create tests in `notification_provider_patch_coverage_test.go` to ensure correct handling of notification provider updates, including blocking type mutations for non-Discord providers.
- Add tests in `security_notifications_patch_coverage_test.go` to verify deprecated headers, handle invalid CIDR warnings, and ensure correct severity handling for security events.
- Introduce migration error handling tests in `routes_coverage_test.go` to ensure graceful handling of migration errors during registration.
- Enhance `cerberus_blockers_test.go` with tests for disabled security event notifications and error handling for dispatch failures.
- Update `router_test.go` to validate notify routing based on feature flags.
- Refactor `mail_service.go` to normalize base URLs for invites, ensuring proper handling of trailing slashes.
- Modify `notification_service_json_test.go` and `notification_service_test.go` to mock Discord validation and improve webhook testing.
- Update `proxyhost_service.go` to enhance hostname validation by parsing URLs.
- Refine `uptime_service.go` to extract ports correctly from URLs, including handling edge cases.
- Enhance frontend tests in `notifications.test.ts` and `Notifications.test.tsx` to ensure correct behavior for Discord notification providers and enforce type constraints.
