Reviewer's Guide

Extend FileUtils::supportLongName() so that ULNFS-mounted paths are treated as supporting long filenames by including the "ulnfs" filesystem type in its internal whitelist.

Extend the set of filesystem types considered to support long filenames to include ULNFS.	Updated the static list of filesystem identifiers in FileUtils::supportLongName() to append the "ulnfs" type. Left existing supported filesystem entries (vfat, exfat, ntfs, ntfs3, fuseblk, fuse.dlnfs, udf) unchanged, preserving current behavior.	src/dfm-base/utils/fileutils.cpp

我来对这段代码的修改进行审查：

1. 语法逻辑：

• 修改是在静态QList中添加了一个新的文件系统类型"ulnfs"
• 语法上没有问题，使用const static确保了列表只初始化一次
• 代码格式符合规范

2. 代码质量：

• 使用const static是好的实践，避免了重复初始化
• 变量命名清晰，datas和fileSystem都能清楚表达用途
• 建议将datas重命名为更具体的名称，如supportedFileSystems，以提高可读性

3. 代码性能：

• 使用const static确保列表只初始化一次，性能良好
• 查找操作使用QList的contains方法，时间复杂度为O(n)
• 如果这个列表会继续增长，建议考虑使用QSet来提高查找效率，将时间复杂度降为O(1)

4. 代码安全：

• 修改本身是安全的，只是添加了一个新的文件系统类型支持
• 建议添加注释说明"ulnfs"文件系统的具体用途，方便其他开发者理解

改进建议：

1. 将变量名改为更具描述性的名称：

const static QList<QString> supportedFileSystems {
    "vfat", "exfat", "ntfs", "ntfs3", "fuseblk", "fuse.dlnfs", "udf", "ulnfs"
};

2. 如果查找性能是关键，考虑使用QSet：

const static QSet<QString> supportedFileSystems {
    "vfat", "exfat", "ntfs", "ntfs3", "fuseblk", "fuse.dlnfs", "udf", "ulnfs"
};

3. 添加注释说明新增文件系统的用途：

// ulnfs: User Level Network File System support
const static QList<QString> supportedFileSystems {
    // ... other file systems ...
    "ulnfs"
};

总的来说，这个修改是合理的，主要是增加了对新文件系统类型的支持。建议的改进主要是为了提高代码的可维护性和性能。
