[SqliteWAL]: 重构示例并优化SQLite配置
- 文件重命名: 将`databasetest`和`databaseutils`统一重命名为`sqlitetest`和`sqliteutils`,保持命名一致性
- 文档更新: 替换README中WAL模式说明为官方文档链接,明确工程实践方案
- 功能增强:
- 增加`readLastRecord()`方法支持读取最后插入的记录
- 添加`local_time`字段存储本地格式化时间戳
- SQL优化:
- 增加WAL模式下的PRAGMA优化配置(内存映射/自动清理/缓存设置)
- 添加SQLite版本及编译选项的运行时日志输出
- 实现数据库连接关闭时的主动优化操作(ANALYZE/VACUUM)
- 线程安全:
- 明确写入操作使用QMutex串行化避免SQLITE_BUSY错误
- 读取操作无需加锁保证并发性能
- 示例扩展:
- 增加测试手机品牌数量(9个品牌)
- 每个写入线程增加读取最后记录操作
- 健壮性提升:
- 数据库连接移除时增加资源清理
- 首次运行时删除旧测试数据库
- 增强错误日志输出1 parent 46796cf commit 6bb5d24
