I hope I am not wrong here with my (first posted) question.
I’m getting wrong/different resourceValues with following code (it lists all directory items in the sandbox directory).
The „URL-method“ returns for some directory items other resourceValues for execute/read/write than the „path-methods“.
For instance folder „SystemData“:
- with „URL-method“: isExecutable=true, isReadable=true, isWritable=true
- with „path-methods“: isExecutableFile: true, isReadableFile: false, isWritableFile: false
The PosixPermissions for this folder gives me 755 … which is not correct.
So two questions:
- Why am I getting different values depending on method and which one are correct?
- Why are the PosixPermissions wrong?
I'm thankful for any help!
