Fri, 06 Feb 2015 08:13:17 -0800

Issue Type: Improvement Improvement
Assignee: Unassigned
Components: core
Created: 06/Feb/15 4:11 PM
Description:

Commonly need to verify that file paths provided by a user are really relative and do not refer to locations outside a workspace or the like. Should have something in Util along the lines of

public static boolean isInside(File root, File f) throws IOException {
    String path = f.getCanonicalPath();
    String rootPath = root.getCanonicalPath();
    return path.equals(rootPath) || path.startsWith(rootPath + File.separatorChar);
}


and a matching method in FilePath.
