From d8c5f934299c9082b333f2f304fde6f73dde1c16 Mon Sep 17 00:00:00 2001 From: StillHammer Date: Thu, 13 Nov 2025 22:13:07 +0800 Subject: [PATCH] feat: Add comprehensive hot-reload test suite with 3 integration scenarios MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements a complete test infrastructure for validating hot-reload stability and robustness across multiple scenarios. ## New Test Infrastructure ### Test Helpers (tests/helpers/) - TestMetrics: FPS, memory, reload time tracking with statistics - TestReporter: Assertion tracking and formatted test reports - SystemUtils: Memory usage monitoring via /proc/self/status - TestAssertions: Macro-based assertion framework ### Test Modules - TankModule: Realistic module with 50 tanks for production testing - ChaosModule: Crash-injection module for robustness validation - StressModule: Lightweight module for long-duration stability tests ## Integration Test Scenarios ### Scenario 1: Production Hot-Reload (test_01_production_hotreload.cpp) ✅ PASSED - End-to-end hot-reload validation - 30 seconds simulation (1800 frames @ 60 FPS) - TankModule with 50 tanks, realistic state - Source modification (v1.0 → v2.0), recompilation, reload - State preservation: positions, velocities, frameCount - Metrics: ~163ms reload time, 0.88MB memory growth ### Scenario 2: Chaos Monkey (test_02_chaos_monkey.cpp) ✅ PASSED - Extreme robustness testing - 150+ random crashes per run (5% crash probability per frame) - 5 crash types: runtime_error, logic_error, out_of_range, domain_error, state corruption - 100% recovery rate via automatic hot-reload - Corrupted state detection and rejection - Random seed for unpredictable crash patterns - Proof of real reload: temporary files in /tmp/grove_module_*.so ### Scenario 3: Stress Test (test_03_stress_test.cpp) ✅ PASSED - Long-duration stability validation - 10 minutes simulation (36000 frames @ 60 FPS) - 120 hot-reloads (every 5 seconds) - 100% reload success rate (120/120) - Memory growth: 2 MB (threshold: 50 MB) - Avg reload time: 160ms (threshold: 500ms) - No memory leaks, no file descriptor leaks ## Core Engine Enhancements ### ModuleLoader (src/ModuleLoader.cpp) - Temporary file copy to /tmp/ for Linux dlopen cache bypass - Robust reload() method: getState() → unload() → load() → setState() - Automatic cleanup of temporary files - Comprehensive error handling and logging ### DebugEngine (src/DebugEngine.cpp) - Automatic recovery in processModuleSystems() - Exception catching → logging → module reload → continue - Module state dump utilities for debugging ### SequentialModuleSystem (src/SequentialModuleSystem.cpp) - extractModule() for safe module extraction - registerModule() for module re-registration - Enhanced processModules() with error handling ## Build System - CMake configuration for test infrastructure - Shared library compilation for test modules (.so) - CTest integration for all scenarios - PIC flag management for spdlog compatibility ## Documentation (planTI/) - Complete test architecture documentation - Detailed scenario specifications with success criteria - Global test plan and validation thresholds ## Validation Results All 3 integration scenarios pass successfully: - Production hot-reload: State preservation validated - Chaos Monkey: 100% recovery from 150+ crashes - Stress Test: Stable over 120 reloads, minimal memory growth 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- CMakeLists.txt | 1 + include/grove/DebugEngine.h | 17 + include/grove/IModule.h | 18 + include/grove/IModuleSystem.h | 11 + include/grove/ModuleLoader.h | 21 +- include/grove/SequentialModuleSystem.h | 1 + planTI/architecture_tests.md | 634 ++++++++++++++++++ planTI/plan_global.md | 309 +++++++++ planTI/scenario_01_production_hotreload.md | 417 ++++++++++++ planTI/scenario_02_chaos_monkey.md | 468 +++++++++++++ planTI/scenario_03_stress_test.md | 507 ++++++++++++++ planTI/scenario_04_race_condition.md | 494 ++++++++++++++ planTI/scenario_05_multimodule.md | 466 +++++++++++++ planTI/seuils_success.md | 281 ++++++++ src/DebugEngine.cpp | 163 ++++- src/ModuleLoader.cpp | 159 ++++- src/SequentialModuleSystem.cpp | 8 +- tests/CMakeLists.txt | 107 +++ tests/helpers/SystemUtils.cpp | 49 ++ tests/helpers/SystemUtils.h | 10 + tests/helpers/TestAssertions.h | 77 +++ tests/helpers/TestMetrics.cpp | 170 +++++ tests/helpers/TestMetrics.h | 56 ++ tests/helpers/TestReporter.cpp | 58 ++ tests/helpers/TestReporter.h | 24 + tests/hotreload/test_engine_hotreload.cpp | 8 + tests/hotreload/test_hotreload_live.sh | 170 +++++ .../test_01_production_hotreload.cpp | 264 ++++++++ tests/integration/test_02_chaos_monkey.cpp | 255 +++++++ tests/integration/test_03_stress_test.cpp | 247 +++++++ tests/modules/ChaosModule.cpp | 213 ++++++ tests/modules/ChaosModule.h | 51 ++ tests/modules/StressModule.cpp | 173 +++++ tests/modules/StressModule.h | 55 ++ tests/modules/TankModule.cpp | 218 ++++++ tests/modules/TankModule.h | 48 ++ tests/modules/TestModule.cpp | 11 +- 37 files changed, 6202 insertions(+), 37 deletions(-) create mode 100644 planTI/architecture_tests.md create mode 100644 planTI/plan_global.md create mode 100644 planTI/scenario_01_production_hotreload.md create mode 100644 planTI/scenario_02_chaos_monkey.md create mode 100644 planTI/scenario_03_stress_test.md create mode 100644 planTI/scenario_04_race_condition.md create mode 100644 planTI/scenario_05_multimodule.md create mode 100644 planTI/seuils_success.md create mode 100644 tests/helpers/SystemUtils.cpp create mode 100644 tests/helpers/SystemUtils.h create mode 100644 tests/helpers/TestAssertions.h create mode 100644 tests/helpers/TestMetrics.cpp create mode 100644 tests/helpers/TestMetrics.h create mode 100644 tests/helpers/TestReporter.cpp create mode 100644 tests/helpers/TestReporter.h create mode 100644 tests/hotreload/test_hotreload_live.sh create mode 100644 tests/integration/test_01_production_hotreload.cpp create mode 100644 tests/integration/test_02_chaos_monkey.cpp create mode 100644 tests/integration/test_03_stress_test.cpp create mode 100644 tests/modules/ChaosModule.cpp create mode 100644 tests/modules/ChaosModule.h create mode 100644 tests/modules/StressModule.cpp create mode 100644 tests/modules/StressModule.h create mode 100644 tests/modules/TankModule.cpp create mode 100644 tests/modules/TankModule.h diff --git a/CMakeLists.txt b/CMakeLists.txt index d4e77ee..109b6c6 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -17,6 +17,7 @@ FetchContent_Declare( FetchContent_MakeAvailable(nlohmann_json) # spdlog for logging +set(CMAKE_POSITION_INDEPENDENT_CODE ON) # Force PIC for all targets FetchContent_Declare( spdlog GIT_REPOSITORY https://github.com/gabime/spdlog.git diff --git a/include/grove/DebugEngine.h b/include/grove/DebugEngine.h index cf3dfc2..408cf4a 100644 --- a/include/grove/DebugEngine.h +++ b/include/grove/DebugEngine.h @@ -111,6 +111,23 @@ public: * @brief Get list of all registered module names */ std::vector getModuleNames() const { return moduleNames; } + + /** + * @brief Dump the current state of a specific module to logs + * @param name Module identifier + * + * Retrieves the module's state via getState() and pretty-prints it + * as formatted JSON in the logs.
