Versioning](https://semver.org/spec/v2.0.0 ### Added +- **Universal JSON Template Support for Notifications**: JSON payload templates (minimal, detailed, custom) are now available for all notification services that support JSON payloads, not just generic webhooks (PR #XXX) + - **Discord**: Rich embeds with colors, fields, and custom formatting + - **Slack**: Block Kit messages with sections and interactive elements + - **Gotify**: JSON payloads with priority levels and extras field + - **Generic webhooks**: Complete control over JSON structure + - **Template variables**: `{{.Title}}`, `{{.Message}}`, `{{.EventType}}`, `{{.Severity}}`, `{{.HostName}}`, `{{.Timestamp}}`, and more + - See [Notification Guide](docs/features/notifications.md) for examples and migration guide +- **Improved Uptime Monitoring Reliability**: Enhanced uptime monitoring system with debouncing and race condition prevention (PR #XXX) + - **Failure debouncing**: Requires 2 consecutive failures before marking host as "down" to prevent false alarms from transient issues + - **Increased timeout**: TCP connection timeout raised from 5s to 10s for slow networks and containers + - **Automatic retries**: Up to 2 retry attempts with 2-second delay between attempts + - **Synchronized checks**: All host checks complete before database reads, eliminating race conditions + - **Concurrent processing**: All hosts checked in parallel for better performance + - See [Uptime Monitoring Guide](docs/features/uptime-monitoring.md) for troubleshooting tips + +### Changed + +- **Notification Backend Refactoring**: Renamed internal function `sendCustomWebhook` to `sendJSONPayload` for clarity (no user impact) +- **Frontend Template UI**: Template configuration UI now appears for Discord, Slack, Gotify, and generic webhooks (previously webhook-only) + +### Fixed + +- **Uptime False Positives**: Resolved issue where proxy hosts were incorrectly reported as "down" after page refresh due to timing and race conditions +- **Transient Failure Alerts**: Single network hiccups no longer trigger false down notifications due to debouncing logic + +### Test Coverage Improvements + - **Test

-### Phase 2: Pre-Commit Integration -- [ ] Create `scripts/pre-commit-hooks/codeql-go-scan.sh` -- [ ] Create `scripts/pre-commit-hooks/codeql-js-scan.sh` -- [ ] Create `scripts/pre-commit-hooks/codeql-check-findings.sh` -- [ ] Make scripts executable: `chmod +x scripts/pre-commit-hooks/codeql-*.sh` -- [ ] Update `.pre-commit-config.yaml` with new hooks -- [ ] Test hooks: `pre-commit run codeql-go-scan --all-files` -- [ ] Test findings check: `pre-commit run codeql-check-findings --all-files` -- [ ] Update `.gitignore` (already has `codeql-db-*/`, `*.sarif` - verify) - -### Phase 3: CI/CD Enhancement -- [ ] Update `.github/workflows/codeql.yml` with result checking steps -- [ ] Create `.github/workflows/codeql-issue-reporter.yml` (optional) -- [ ] Test CI workflow on a test branch -- [ ] Verify step summary shows findings count -- [ ] Verify CI fails on high-severity findings -- [ ] Document CI behavior in workflow comments - -### Phase 4: Documentation -- [ ] Create `docs/security/codeql-scanning.md` -- [ ] Update `.github/instructions/copilot-instructions.md` Definition of Done -- [ ] Update `docs/security.md` with CodeQL section (if needed) -- [ ] Add CodeQL badge to `README.md` (optional) -- [ ] Create troubleshooting guide section -- [ ] Document CI-local alignment in CONTRIBUTING.md - -### Phase 5: Verification -- [ ] Run full security scan locally: `pre-commit run codeql-go-scan codeql-js-scan codeql-check-findings --all-files` -- [ ] Push to test branch and verify CI matches local results -- [ ] Verify no false positives between local and CI -- [ ] Test SARIF viewer integration in VS Code -- [ ] Confirm all documentation links work - ---- - -## Success Metrics - -### Before Implementation -- โŒ Local CodeQL uses different query suite than CI (security-extended vs security-and-quality) -- โŒ Security issues pass locally but fail in CI -- โŒ No pre-commit integration for CodeQL -- โŒ No clear developer workflow for security scans -- โŒ No automated issue creation for findings - -### After Implementation -- โœ… Local CodeQL uses identical parameters to CI -- โœ… Local scan results match CI 100% -- โœ… Pre-commit hooks catch HIGH/CRITICAL issues before push -- โœ… Clear documentation and workflow for developers -- โœ… CI blocks merge on high-severity findings -- โœ… Automated GitHub Issues for critical vulnerabilities (optional) - ---- - -## Timeline Estimate - -- **Phase 1 (CodeQL Alignment):** 1-2 hours - - Update tasks.json: 30 min - - Testing and verification: 1 hour - - SARIF viewer setup: 30 min - -- **Phase 2 (Pre-Commit Integration):** 2-3 hours - - Create scripts: 1 hour - - Update pre-commit config: 30 min - - Testing: 1 hour - - Troubleshooting: 30 min - -- **Phase 3 (CI/CD Enhancement):** 1-2 hours - - Update codeql.yml: 30 min - - Create issue reporter (optional): 1 hour - - Testing: 30 min - -- **Phase 4 (Documentation):** 2-3 hours - - Write security scanning guide: 1.5 hours - - Update copilot instructions: 30 min - - Update other docs: 1 hour - -**Total Estimate:** 6-10 hours - ---- - -## Risks & Mitigations - -### Risk 1: Performance Impact on Pre-Commit -**Impact:** CodeQL scans take 2-3 minutes, slowing down commits -**Mitigation:** Use `stages: [manual]` - developers run scans on-demand, not on every commit -**Alternative:** CI catches issues, but slower feedback loop - -### Risk 2: Breaking Changes to Existing Workflows -**Impact:** Developers accustomed to old tasks -**Mitigation:** -- Keep old task names with deprecation notice for 1 week -- Send announcement with migration guide -- Update all documentation immediately - -### Risk 3: CI May Fail on Existing Code -**Impact:** Blocking all PRs if existing code has high-severity findings -**Mitigation:** -- Run full scan on main branch FIRST -- Fix or suppress existing findings before enforcing CI blocking -- Grandfather existing issues, block only new findings (use baseline) - -### Risk 4: False Positives -**Impact:** Developers frustrated by incorrect findings -**Mitigation:** -- Document suppression syntax: `// codeql[rule-id] - Reason` -- Create triage process for false positives -- Contribute fixes to CodeQL queries if needed - ---- - -## Rollout Plan - -### Week 1: Development & Testing -- Implement Phase 1 (Tasks) -- Implement Phase 2 (Pre-Commit) -- Test on development branch - -### Week 2: CI & Documentation -- Implement Phase 3 (CI Enhancement) -- Implement Phase 4 (Documentation) -- Run full scan on main branch, triage findings - -### Week 3: Team Training -- Send announcement email with guide -- Hold team meeting to demo new workflow -- Create FAQ based on questions - -### Week 4: Enforcement -- Enable CI blocking on HIGH/CRITICAL findings -- Monitor for issues -- Iterate on documentation -
