79-80: Consider returning a reference instead of a raw pointer.The
GetEventServer()method returns a raw pointer to a resource managed byunique_ptr. To prevent potential lifetime management issues, consider returning a reference instead:- net::EventServer<std::shared_ptr<kiwi::PClient>>* GetEventServer() { return event_server_.get(); } + net::EventServer<std::shared_ptr<kiwi::PClient>>& GetEventServer() { return *event_server_; }

Add thread safety and validation to UpdateOptions.
The UpdateOptions method modifies shared state without synchronization and lacks input validation. Consider:
- Adding thread safety mechanisms
- Validating the new options before applying them
- Ensuring thread capacity reservation is safe during runtime
- void UpdateOptions(const NetOptions &newOptions) {
- opt_ = newOptions;
- threadsManager_.reserve(opt_.GetThreadNum());
- }
+ void UpdateOptions(const NetOptions &newOptions) {
+ if (newOptions.GetThreadNum() <= 0) {
+ throw std::invalid_argument("Thread number must be greater than 0");
+ }
+ std::lock_guard<std::mutex> lock(mtx_);
+ opt_ = newOptions;
+ if (threadsManager_.capacity() < opt_.GetThreadNum()) {
+ threadsManager_.reserve(opt_.GetThreadNum());
+ }

Add error handling for log level and redis mode settings.
The configuration updates lack error handling. Consider adding try-catch blocks for potential exceptions:
- if (key == "log_level") g_kiwi->options_.SetLogLevel(value);
- if (key == "redis_compatible_mode") g_kiwi->options_.SetRedisCompatibleMode(stoi(value));
+ if (key == "log_level") {
+ g_kiwi->options_.SetLogLevel(value);
+ }
+ if (key == "redis_compatible_mode") {
+ try {
+ g_kiwi->options_.SetRedisCompatibleMode(stoi(value));
+ } catch (const std::exception& e) {
+ return Status::InvalidArgument("Invalid redis compatible mode value");
+ }

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Add proper error handling and validation for thread number updates.
The thread number configuration has several issues:
- Unsafe use of
stoi()without error handling - Map access without iterator validation
- Missing validation of thread number ranges
- Potential integer overflow when adding thread numbers
if (key == "worker_threads_num") {
- g_kiwi->options_.SetThreadNum(stoi(value) + stoi((config_map_.find("salve_threads_num"))->second->Value()));
- g_kiwi->GetEventServer()->UpdateOptions(g_kiwi->options_);
+ try {
+ auto slave_it = config_map_.find("salve_threads_num");
+ if (slave_it == config_map_.end()) {
+ return Status::InvalidArgument("Slave threads configuration not found");
+ }
+ int worker_threads = stoi(value);
+ int slave_threads = stoi(slave_it->second->Value());
+ if (worker_threads <= 0 || slave_threads <= 0) {
+ return Status::InvalidArgument("Thread numbers must be positive");
+ }
+ int64_t total_threads = static_cast<int64_t>(worker_threads) + static_cast<int64_t>(slave_threads);
+ if (total_threads > THREAD_MAX) {
+ return Status::InvalidArgument("Total thread count exceeds maximum limit");
+ }
+ g_kiwi->options_.SetThreadNum(static_cast<int>(total_threads));
+ g_kiwi->GetEventServer()->UpdateOptions(g_kiwi->options_);
+ } catch (const std::exception& e) {
+ return Status::InvalidArgument("Invalid thread number value");
+ }
}Also, there appears to be a typo in the configuration key "salve_threads_num". Should it be "slave_threads_num"?

每次 set config后,先判断 option 内容是否变化，如果option 内容变了, 重新复制一个 option 传递都 net
