merge_real_time_db无法实现合并实时数据库

[joycedoor]

问题描述 版本更新后merge_real_time_db无法使用了。以前这个函数接受5个参数，包括开始时间戳和结束时间戳，现在不接受两个时间戳变量了。因此我对自己的代码微调了一下：

复现步骤 merge_real_time_db(wx_info["key"], ”./tmp/MergedDB.db“, ['C:\xx\Msg\MicroMsg.db', 'C:\xx\Msg\Multi\MSG0.db'])

使用如上代码，期望能够将MSG数据库和MicroMsg数据库的实时数据合并到一个大的MergedDB.db文件中

实际行为 并没有报错，也没有成功合并出数据库

环境信息

• pywxdump版本：3.0.41
• 操作系统版本：WIN11 X64
• python版本：3.8.19
• 微信版本：3.9.11.19

其他信息 请提供任何与问题相关的其他信息（文字，截图等）。

请修改这个函数，然后查看一下日志，看看返回内容是什么

直接运行的话，返回的是None，我print 出来了out 和 err，分别是 b'ERROR I 1.\r\nERROR 4.\r\n' 和 b''

现在我将输入路径修改为了绝对路径，用这段代码试试看看是否可以呢

这样可以了，成功了，感谢。 不过wx_core_loger是啥，好像没有这个函数.

[joycedoor]

是否可以更新一个小版本呢，修复一下这一块，万分感谢！

[xaoyaoo]

wx_core_loger，是我之后版本准备采用的统一日志处理
