Attila Szegedi commented on IO-168:
-----------------------------------
Folks,
file.getCanonicalFile().equals(file.getAbsoluteFile())
won't return true only for a symlink. It will also return true for a file that
has at least one symlinked directory in its path.
This will work as expected though:
File canonicalDir = file.getParentFile().getCanonicalFile();
File fileInCanonicalDir = new File(canonicalDir, file.getName());
return
fileInCanonicalDir.getCanonicalFile().equals(fileInCanonicalDir.getAbsoluteFile());

> Key: IO-168
> URL: https://issues.apache.org/jira/browse/IO-168
> Project: Commons IO
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 1.4
> Environment: Linux only (symlinks required for bug to manifest)
> Reporter: Apostolos Lerios
>
> If 'dlink' is a symbolic link to a directory 'dir', and FileUtils.forceDelete
> is called on dlink, then here is what happens:
> 1) the contents of 'dir' are emptied (the link is followed).
> 2) 'dir' continues to exist (but is empty).
> 3) 'dlink' is removed.
> The correct behavior is to simply remove 'dlink' without following it and
> thus without altering the contents of 'dir' (or 'dir' itself).
