[重构SqliteWAL示例并增强其功能]: 重命名类以更明确地表示针对SQLite,增加多线程下的读写操作示例,优化SQLite配置以提高性能,并增加连接管理
- 重命名文件和数据类: 将`databasetest`和`databaseutils`改为`sqlitetest`和`sqliteutils`,以更明确地表示针对SQLite数据库
- 更新README说明: 增加官方文档链接,强调最佳工程实践(写入操作使用QMutex串行化,读取操作不需要加锁)
- 增强SqliteTest类功能: 增加`readLastRecord`方法用于读取最后一条记录,使用`std::call_once`确保数据库文件只删除一次,改进表创建语句(使用IF NOT EXISTS)
- 优化SQLite配置: 在`sqliteutils.cc`中增加多个PRAGMA设置(如WAL模式、自动VACUUM、内存临时表等)以提升性能,并增加在连接关闭时的清理操作(如分析、优化、VACUUM等)
- 增加日志输出: 输出SQLite版本、编译选项和驱动特性,便于调试和了解运行环境
- 改进连接管理: 引入连接计数机制,确保在最后一个连接关闭时执行清理操作并移除数据库连接1 parent 46796cf commit c3173d0
