# Changelog
## 2025-05-29 - 19.5.3 - fix(smartproxy)
Fix route security configuration location and improve ACME timing tests and socket mock implementations
- Move route security from action.security to the top-level route.security to correctly enforce IP allow/block lists (addresses failing in test.route-security.ts)
- Update readme.problems.md to document the routing security configuration issue with proper instructions
- Adjust certificate metadata in certs/static-route/meta.json with updated timestamps
- Update test.acme-timing.ts to export default tap.start() instead of tap.start() to ensure proper parsing
- Improve socket simulation and event handling mocks in test.http-fix-verification.ts and test.http-forwarding-fix.ts to more reliably mimic net.Socket behavior
- Minor adjustments in multiple test files to ensure proper port binding, race condition handling and route lookups (e.g. getRoutesForPort implementation)
## 2025-05-29 - 19.5.2 - fix(test)
Fix ACME challenge route creation and HTTP request parsing in tests

- SmartProxy forwards raw HTTP data to HttpProxy's HTTPS port
**Impact**: Plain HTTP connections cannot be handled by HttpProxy, despite `useHttpProxy` configuration suggesting this should work.
**Root Cause**: Design mismatch - HttpProxy is designed for HTTPS/TLS termination, not plain HTTP forwarding.
**Status**: Documented. The `useHttpProxy` configuration should only be used for ports that receive TLS connections requiring termination. For plain HTTP forwarding, use direct forwarding without HttpProxy.
**Status**: Documented. The `useHttpProxy` configuration should only be used for ports that receive TLS connections requiring termination. For plain HTTP forwarding, use direct forwarding without HttpProxy.
## 9. Route Security Configuration Location Issue
**Problem**: Tests were placing security configuration in `route.action.security` instead of `route.security`.
**Evidence**:
- `test.route-security.ts` - IP block list test failing because security was in wrong location
- IRouteConfig interface defines security at route level, not inside action
**Impact**: Security rules defined in action.security were ignored, causing tests to fail.
**Status**: ✅ FIXED - Updated tests to place security configuration at the correct location (route.security).
