## Description
|
|
|
|
Review the full integration and deployment readiness. This is the final review before the proxy is considered production-ready.
|
|
|
|
### Review Checklist
|
|
|
|
1. **Startup sequence**:
|
|
- All components initialize in the correct order
|
|
- Fail-fast on any initialization error
|
|
- All ports bound before accepting connections
|
|
- `sd_notify("READY=1")` sent correctly
|
|
|
|
2. **Config reload**:
|
|
- SIGHUP reload works correctly
|
|
- Admin socket `reload` and `status` commands work
|
|
- Reload serialization prevents race conditions
|
|
- Static config change detection logs warnings
|
|
- Invalid config rejection preserves old config
|
|
|
|
3. **Graceful shutdown**:
|
|
- SIGTERM/SIGINT triggers graceful shutdown
|
|
- Listening sockets closed
|
|
- In-flight requests drained within timeout
|
|
- Background tasks cancelled
|
|
- Exit code 0 on clean shutdown
|
|
|
|
4. **Security**:
|
|
- No information leakage in error responses
|
|
- X-Forwarded-For replaced (not appended)
|
|
- Cipher suites restricted to nginx scope
|
|
- Bind address validation (no 0.0.0.0 unless allowed)
|
|
- Rate limiting effective against basic abuse
|
|
|
|
5. **Production readiness**:
|
|
- Docker image builds and runs correctly
|
|
- Systemd unit file works
|
|
- Health check endpoint responds
|
|
- Log file output in correct format for fail2ban
|
|
- ACME certificate provisioning works (manual testing against staging)
|
|
|
|
6. **Documentation**:
|
|
- Config file examples are correct and complete
|
|
- Deployment guide covers both systemd and container setups
|
|
|
|
## Acceptance Criteria
|
|
|
|
- [ ] Full startup sequence works with both single and multi-listener configs
|
|
- [ ] Config reload via SIGHUP works with feedback in logs
|
|
- [ ] Config reload via admin socket works with structured JSON feedback
|
|
- [ ] Graceful shutdown completes within timeout
|
|
- [ ] No error response leaks version or identity information
|
|
- [ ] Docker image builds and passes health check
|
|
- [ ] Systemd unit file is correct
|
|
- [ ] fail2ban filter matches `RATE_LIMIT` log format
|
|
- [ ] All tests pass: `cargo test`
|
|
- [ ] No clippy warnings: `cargo clippy`
|
|
- [ ] Formatting clean: `cargo fmt --check`
|
|
- [ ] Manual testing against ACME staging succeeds
|

## Notes
|
|
|
|
> This review should be thorough and practical. Manual testing against ACME staging should be done at this point. Any deviations from the spec should be documented and accepted or fixed.

## Summary
|
|
|
|
> All acceptance criteria met. Startup, config reload, security, production readiness, and code quality all pass. Graceful shutdown drain was implemented (using InFlightCounter + RAII guard + timeout-based polling). Formatting and clippy clean. 186 unit tests + 35 integration tests pass (1 known flaky logging test due to global state). |
