Conversation
Complete audit covering: - 64 total issues identified across all categories - 13 high-severity items requiring attention before field deployment - Security vulnerabilities (authentication, encryption, log sanitization) - Missing functionality for 24/7/365 operation (watchdog, remote monitoring) - Test coverage analysis showing gaps in critical paths - Prioritized 4-phase remediation plan - Field deployment readiness checklist This audit ensures LyreBirdAudio is ready for wildlife audio recording deployments requiring 24/7/365 stability and reliability.
Phase 1 - Security & Reliability: - Add .gitignore to prevent committing sensitive/generated files - Add docs/SECURITY.md with optional security features: - RTSP authentication (internal users) - TLS/HTTPS encryption with certificate setup - API security and network hardening - Firewall configuration (UFW/iptables) - Physical security for field deployments - Add systemd service files with watchdog support: - config/mediamtx.service - config/mediamtx-audio.service - WatchdogSec for automatic restart on hangs Phase 2 - Operations: - Add config/lyrebird-logrotate.conf for log management - Add lyrebird-storage.sh for disk space management: - Configurable retention policies - Emergency cleanup on disk full - Cron integration for automated cleanup - Expand test suite to ~90 tests (~50% coverage): - test_usb_audio_mapper.bats (15 tests) - test_lyrebird_diagnostics.bats (16 tests) - test_lyrebird_orchestrator.bats (14 tests) - Enhanced test_stream_manager.bats (+20 tests) Phase 3 - Monitoring: - Add lyrebird-metrics.sh for Prometheus integration: - MediaMTX service metrics - Stream manager metrics - Per-stream metrics - USB device metrics - System resource metrics - HTTP server mode or file output for node_exporter All security features are optional - casual home users can run without authentication or encryption on trusted networks.
Add lyrebird-metrics.sh and lyrebird-storage.sh to component reference table, add new Configuration Files section documenting systemd services, logrotate config, and security guide.
Phase B implementation completing medium-priority items: New features: - lyrebird-alerts.sh: Pure-bash webhook alerting system - Supports Discord, Slack, ntfy.sh, Pushover, generic HTTP - Rate limiting and alert deduplication - Interactive setup wizard Documentation: - CHANGELOG.md: Version history following Keep a Changelog format - CONTRIBUTING.md: Contribution guidelines and coding standards UX improvements: - Progress indicators in lyrebird-common.sh (spinner, progress bar) - Enhanced error messages with remediation steps - Inline comments explaining complex regex patterns in usb-audio-mapper.sh Updated README with new lyrebird-alerts.sh reference.
Documentation updates: - Add detailed README sections for lyrebird-alerts.sh, lyrebird-metrics.sh, and lyrebird-storage.sh with usage examples and configuration - Add links to CHANGELOG.md and CONTRIBUTING.md in Development section New test files (~136 new tests): - test_lyrebird_alerts.bats (45 tests): formatters, rate limiting, alert types - test_lyrebird_metrics.bats (32 tests): metrics collection, Prometheus format - test_lyrebird_storage.bats (42 tests): cleanup, retention, disk usage Enhanced existing tests: - test_lyrebird_common.bats: Added 17 tests for progress indicators and error helper functions Updated tests/README.md with new test files and coverage summary. Total test count now ~226 tests covering ~55% of critical paths.
- Add tests/test_lyrebird_updater.bats (55 tests) covering: - Logging and lock functions - Service detection and backup - Git state and transactions - Version and release management - Add tests/test_install_mediamtx.bats (55 tests) covering: - Version comparison logic - Platform detection - URL and version validation - Service creation and control - Add tests/test_lyrebird_mic_check.bats (45 tests) covering: - Device name sanitization - Capability detection - Configuration generation - ALSA device parsing - Expand test_lyrebird_orchestrator.bats (+30 tests) for: - Service status parsing - Port and stream name validation - Time formatting - PID validation - Expand test_lyrebird_diagnostics.bats (+18 tests) for: - File size calculations - System resource monitoring - Network interface detection - Log analysis - Update tests/README.md with new coverage metrics: - Total tests: ~464 (up from ~226) - Estimated coverage: ~70% (up from ~55%)
- SC2155: Declare and assign separately to avoid masking return values - lyrebird-alerts.sh: SCRIPT_DIR - lyrebird-metrics.sh: SCRIPT_NAME - lyrebird-storage.sh: SCRIPT_NAME - SC2034: Add shellcheck disable comments for intentionally unused variables - lyrebird-alerts.sh: ALERT_LEVEL_* and ALERT_TYPE_CUSTOM (exported constants) - lyrebird-common.sh: LYREBIRD_SPINNER_SIMPLE (alternative spinner) - lyrebird-metrics.sh: MEDIAMTX_RTSP_PORT (available for external use)
