Andy Taylor	c2406d9f11	Remove wxWidgets, port to standalone C++17 with cross-platform support ... Replace the wxWidgets dependency with standard C++17 throughout the entire codebase, producing a clean, portable, thoroughly reviewed CLI daemon that builds on Linux, Windows, and macOS without any GUI toolkit. == Removed == - GUI application and config editor (DStarRepeaterFrame, DStarRepeaterConfig/) - GUI widget library (GUICommon/) - Windows USB drivers (WindowsUSB/) - Visual Studio solutions and project files (.sln, .vcxproj) - NSIS installer scripts, platform-specific makefiles - wxWidgets-specific files (LogEvent, LogRedirect, GMSKModemWinUSB) - Dead code: unused GUI constants, vestigial command methods, unused DTMF/queue constants in non-TRX thread variants == Core conversion (all source files) == - wxString -> std::string, wxArrayString -> std::vector<std::string> - wxFloat32 -> float, wxUint8/16/32 -> uint8_t/16_t/32_t - wxThread -> std::thread, wxMutex -> std::mutex - wxStopWatch -> std::chrono::steady_clock - wxRegEx -> std::regex, wxDynLib -> dlopen/dlsym - wxFFile -> FILE*, wxTextFile -> std::ifstream - WX_DECLARE_STRING_HASH_MAP -> std::unordered_map - volatile -> std::atomic for ring buffer and cross-thread flags - NULL -> nullptr throughout == INI config format (MMDVMHost compatible) == - [Section]/Key=Value INI format replaces flat key=value - Config file path is the single required command-line argument: dstarrepeaterd <config-file> - [Log] section: FilePath, FileLevel, DisplayLevel, MQTTLevel (levels 0-6 matching MMDVMHost convention) - [Paths] section: Data and Audio directories from config - [Whitelist]/[Blacklist]/[Greylist] file paths from config - All compile-time path defines (CONF_DIR, LOG_DIR) removed - Example config: Data/dstarrepeater.ini.example == Build system == - Plain g++ -std=c++17, no wx-config dependency - Defaults: release build, MQTT on, GPIO auto-detected - GPIO auto-detection checks uname -s (Linux only) and uname -m (arm/aarch64) to avoid false match on macOS Apple Silicon - Zero warnings with -Wall on GCC 13 - Verified on Ubuntu 24.04, Debian Trixie, and Alpine 3.21 == Install layout == - Binary: /usr/bin/dstarrepeaterd - AMBE voice data: /usr/share/dstarrepeater/ - Config directory: /etc/dstarrepeater/ (created on install) - Example config: /etc/dstarrepeater/dstarrepeater.ini.example == Cross-platform support == - EndianCompat.h: byte-swap functions for Linux, macOS, and Windows - Serial ports: Win32 CreateFile/ReadFile/WriteFile alongside POSIX - Sockets: Winsock2 with RAII WSAStartup alongside POSIX - Sound card: PortAudio for Windows/macOS, ALSA for Linux - All platform code is additive (#ifdef _WIN32), no Linux code changed == Standalone logger == - Thread-safe file logger with std::mutex and daily UTC rotation - Level-based filtering for file, display (stdout), and MQTT sinks - LogLevel enum matches MMDVMHost numbering (1=Debug through 6=Fatal) - Thread-safe gmtime via gmtime_r/gmtime_s - Atomic singleton for safe cross-thread access == Display-Driver MQTT compatibility == - All JSON messages match Display-Driver's expected format exactly - D-Star start/end/lost events with callsigns and source (rf/net) - BER updates during active RF - DVAP RSSI signal strength publishing - Slow-data text forwarding - MMDVM idle mode transitions - JSON escaping on all callsign/text fields from over-the-air data - JSON schema: schema.json with validated $defs structure == Security and safety fixes == - All cross-thread bool flags: std::atomic<bool> - MQTTConnection m_connected and DVAP m_signal/m_squelchOpen: atomic - RingBuffer: std::atomic<unsigned int> for ARM correctness - All sprintf -> snprintf to prevent buffer overflows - JSON escaping for all MQTT output from untrusted sources - DVTOOLFileWriter filename sanitization (path traversal prevention) - Thread-safe localtime_r/localtime_s in DVTOOLFileWriter - GatewayProtocolHandler: bounded string from network buffer - Integer underflow guards in protocol handler readData() - Buffer bounds checks in writePoll()/writeRegister() - MMDVM printDebug() minimum length guards - PID file: /var/run with O_NOFOLLOW, PID written for systemd - Exception-safe createThread() with full cleanup on failure - Deprecated gethostbyname() replaced with getaddrinfo() - CRLF stripping in callsign list loader - Infinite loop exits in DVAP resync() and serial getResponse() - Null guards in SoundCardReaderWriter::close() - RingBuffer::hasSpace() off-by-one fixed == Memory safety == - Delete protocol handler, modem, controller on open()/start() failure - Thread destructors clean up all owned objects with null-after-delete - Callsign lists properly deleted in TX/RX/TXRX thread no-op setters - BeaconUnit buffer allocation matched to actual write size (DV_FRAME) - Null dereference fix in endOfNetworkData() for network-first streams == Functional fixes == - Restored DTMF command execution (system() via checkControl()) - Fixed getControl() parameter order (commands 3-6 were swapped) - Fixed getStatus() argument order in idle branch (BER was at wrong position, causing MQTT to report garbage BER when idle) - Added missing GMSK interface type config parsing - Fixed IcomController uninitialized buffer and sync check order - Fixed SplitController format string vulnerability - Fixed DVAPController dumpPackets() dead loop - Inline const arrays in DStarDefines.h (ODR compliance) == Documentation == - Comprehensive comments added to all source files - README.md: quick start, dependency tables, usage guide - CONFIGURATION.md: complete INI format reference - MQTT.md: updated for INI config, Display-Driver integration - BUILD.md: per-platform instructions (Linux, Windows, macOS) - CHANGELOG.md: version history, newest first - schema.json: JSON schema for all MQTT messages Version bumped to 20260319.	4 months ago
Andy Taylor	6dc8097d20	Add optional MQTT support, Display-Driver compatibility, and documentation ... MQTT telemetry (build with make MQTT=1) --------------------------------------- Add optional MQTT publishing to DStarRepeater, following the same conventions as MMDVMHost: CMQTTConnection wrapping libmosquitto, topic-prefix convention ({name}/topic), log-level filtering, PID-based client IDs, and matching config key names. All MQTT code is guarded by #if defined(MQTT) — without the flag, the binary is unchanged. Three topics are published: {name}/log Timestamped log messages filtered by severity {name}/status JSON repeater state snapshot, once per second {name}/json Display-Driver-compatible events at state transitions Display-Driver compatibility ---------------------------- Publish event-driven JSON on the "json" topic in the exact format that Display-Driver expects, enabling OLED/TFT display output with no changes to Display-Driver. Events: D-Star start (RF/net with callsign fields), end, lost (watchdog), idle, and BER. Hooks added at every state transition point in all four thread variants (TRXThread, RXThread, TXThread, TXRXThread). Shutdown safety --------------- Add mosquitto_loop_stop() before mosquitto_destroy() in close() to prevent use-after-free from the background network thread. Add Wait() after kill() in OnExit() so the repeater thread has fully exited before tearing down MQTT. Both issues also exist in MMDVMHost. Config parser bug fix --------------------- The config file parser called GetNextLine() inside comment and no-equals handlers before continuing, but the for-loop increment already advances — silently skipping the line after every comment or blank line. Remove the redundant calls and add an empty-line guard. Comments and blank lines now work correctly in config files. Documentation and config ------------------------ Add MQTT.md with build instructions, config keys, topic structure, JSON examples, and Display-Driver compatibility details. Add CONFIGURATION.md as a full reference guide for every config setting. Update README.md with gateway links (ircDDBGateway, DStarGateway) and MQTT build instructions. Rename and update the example config with corrected defaults, missing icomPort, and MQTT settings.	5 months ago
