It looks a bit weird that we do it for the rolling appender but not for the other appender types. Is it possible that some update will not get applied because of a cached old value? ########## File path: libminifi/src/core/logging/LoggerConfiguration.cpp ########## @@ -359,6 +323,57 @@ void LoggerConfiguration::initializeCompression(const std::lock_guard<std::mutex } } +std::shared_ptr<spdlog::sinks::rotating_file_sink_mt> LoggerConfiguration::getRotatingFileSink(const std::string& appender_key, const std::shared_ptr<LoggerProperties>& properties) { + static std::map<std::filesystem::path, std::shared_ptr<spdlog::sinks::rotating_file_sink_mt>> rotating_file_sinks; + static std::mutex sink_map_mtx; + + std::string file_name; + if (!properties->getString(appender_key + ".file_name", file_name)) { + file_name = "minifi-app.log"; + } + std::string directory; + if (!properties->getString(appender_key + ".directory", directory)) { + // The below part assumes logger_properties->getHome() is existing + // Cause minifiHome must be set at MiNiFiMain.cpp? + directory = properties->getHome() + utils::file::FileUtils::get_separator() + "logs"; + } + + file_name = directory + utils::file::FileUtils::get_separator() + file_name; + if (utils::file::FileUtils::create_dir(directory) == -1) { + std::cerr << directory << " cannot be created\n"; + exit(1); + } + + int max_files = 3; + std::string max_files_str = ""; + if (properties->getString(appender_key + ".max_files", max_files_str)) { + try { + max_files = std::stoi(max_files_str); + } catch (const std::invalid_argument &) { + } catch (const std::out_of_range &) { + } + } + + int max_file_size = 5_MiB; + std::string max_file_size_str = ""; + if (properties->getString(appender_key + ".max_file_size", max_file_size_str)) { + try { + max_file_size = std::stoi(max_file_size_str); + } catch (const std::invalid_argument &) { + } catch (const std::out_of_range &) { + } + } + + std::lock_guard<std::mutex> guard(sink_map_mtx); + auto it = rotating_file_sinks.find(file_name); + if (it != rotating_file_sinks.end()) { + return it->second; + } Review comment: Thanks, makes sense. But I don't think the new comment is clear; something like ``` // According to spdlog docs, if two loggers write to the same file, they must use the same sink object. // Note that some logging configuration changes will not take effect until MiNiFi is restarted. ``` would be better. -- This is an automated message from the Apache Git Service.
