p4 大小写检查

P4 服务器存储文件的路径不一致

背景：p4服务器没有开启文件大小写 + Windows 磁盘上不路径大小写

使用p4 where 本地磁盘目录， 获取Depot中的目录， workspace中的目录，本地磁盘中存储的目录

得到Depot中的目录

//depot/Game/Content/Textures/.png
//depot/Game/Content/textures/T.png

而在P4V中或者控制台中使用p4 dirs 即p4 dirs //depot/Game/Content/* 看到的是：

//depot/Game/Content/Textures

因此，这里遍历本地磁盘中文件，查找本地文件在P4中的Depot中的位置，用P4 dirs 获取Depot中最开始存储的文件夹， 这样就能比较出哪些文件被记录在Depot中文件路径是错误的。

以下是python代码
