Ignored Files and Folders are still watched in WSL

[Pragadesh-45]

Describe the bug

There is an issue with ignored folders when WSL paths are accessed from Windows. I suspect the issue lies in the normalizePathToUnix(sp.isAbsolute(path) ? path : sp.join(cwd, path)) function. [Code reference](

chokidar/src/index.ts

Line 189 in 916334c

return normalizePathToUnix(sp.isAbsolute(path) ? path : sp.join(cwd, path));

)

Versions (please complete the following information):

• Chokidar version: 3.5.3
• Node version: v20.18.1
• OS version: Windows 11

Additional context

I suspect the issue lies in the toUnix function, which is defined for the ignored path. It returns an invalid path when invoked with a valid WSL path.

Example:

> toUnix('\\wsl.localhost\Ubuntu\home\codex_wsl\one-wsl')
'/wsl.localhostUbuntuhomecodex_wslone-wsl'

The current logic is as follows:
https://github.com/paulmillr/chokidar/blob/916334c8a30eb8340f3b6602267ab23a9e31abd0/src/index.ts#L163C1-L178C3

// If SLASH_SLASH occurs at the beginning of the path, it is not replaced
//     because "//StoragePC/DrivePool/Movies" is a valid network path
const toUnix = (string: string) => {
  let str = string.replace(BACK_SLASH_RE, SLASH);
  let prepend = false;
  if (str.startsWith(SLASH_SLASH)) {
    prepend = true;
  }
  while (str.match(DOUBLE_SLASH_RE)) {
    str = str.replace(DOUBLE_SLASH_RE, SLASH);
  }
  if (prepend) {
    str = SLASH + str;
  }
  return str;
};

This logic handles some network paths like smb://192.168.1.10/folder (SMB on Linux), but it fails when accessing SMB and WSL paths from Windows, e.g., \\fileserver\sharedfolder and \\wsl.localhost\Ubuntu\home.

can you provide a reproduction?

you've explained what you think the fix is, but not what the problem is

also, your example is slightly wrong since the string would be escaped if you passed a string literal:

> toUnix('\\\\wsl.localhost\\Ubuntu\\home\\codex_wsl\\one-wsl')
'//wsl.localhost/Ubuntu/home/codex_wsl/one-wsl
