fix collects instance IDs under the lock then releases before per-instance `healthCheck()` calls + - [x] `include/llm/llm_plugin_manager.h`: added `std::atomic plugin_operation_count_{0}` — tracks total `registerPlugin()` calls race-free + - [x] `src/llm/llm_plugin_manager.cpp` `registerPlugin()`: increments `plugin_operation_count_` atomically via `fetch_add(1, memory_order_relaxed)` + - Tests: `tests/llm/test_wave_next_llm_threadsafety.cpp` (L7-TS-01..04) + - L7-TS-01: Concurrent `getModelConfig()` / `getModelStatus()` from 4 threads × 1 000 iterations — no data race + - L7-TS-02: Concurrent `registerModel()` (2 writer threads) + `listModels()` (2 reader threads) — no crash or corruption + - L7-TS-03: `initializeStateStore()` from one thread while another calls `getPlugin()` — no use-after-free on `state_db_` + - L7-TS-04: `registerPlugin()` from 8 threads × 100 registrations — `plugin_operation_count_` == 800 exactly + --- ## Wave A-8 Distributed Optimization Closure (2026-08-16) diff --git a/src/llm/distributed_training_coordinator.cpp b/src/llm/distributed_training_coordinator.cpp index e0ab0c5fb4..4cffef5118 100644 --- a/src/llm/distributed_training_coordinator.cpp +++ b/src/llm/distributed_training_coordinator.cpp @@ -23,6 +23,7 @@ #include #include #include +#include #include #include @@ -1307,15 +1308,19 @@ bool DistributedTrainingCoordinator::saveCheckpoint(int step_number) { std::string checkpoint_file = config_.checkpoint_path + "/checkpoint_step_" + std::to_string(step_number) + ".json";
