Niklas Gustavsson updated FTPSERVER-152: ---------------------------------------- Fix Version/s: (was: 1.0-M2) 1.0-M3 Assignee: Niklas Gustavsson Affects Version/s: (was: 1.0-M3) > NativeFileObject.hasDeletePermission() not working as expected. > ---------------------------------------------------------------- > > Key: FTPSERVER-152 > URL: https://issues.apache.org/jira/browse/FTPSERVER-152 > Project: FtpServer > Issue Type: Bug > Affects Versions: 1.0-M2 > Reporter: David Latorre > Assignee: Niklas Gustavsson > Fix For: 1.0-M3 > > Original Estimate: 0.17h > Remaining Estimate: 0.17h > > In the current implementation, "hasDeletePermission" in NativeFileObject > delegates to hasWritePermission in order to check whether a file can be > deleted or not. But, in most environments, a file can be deleted when it is > parent directory is writable, no matter if the file is writable itself or > not. I attach a fix which attempts to preserve both options: it will check > FTPServer's write permission for the actual file and if its parent directory > is writable. > public boolean hasDeletePermission() { > // root cannot be deleted > if ("/".equals(fileName)) { > return false; > } > /* Added 12/08/2008: in the case that the permission is not > explicitly denied for this file > * we will check if the parent file has write permission as most > systems consider that a file can > * be deleted when their parent directory is writable. > */ > String fullName=getFullName(); > > // we check FTPServer's write permission for this file. > if (user.authorize(new WriteRequest(fullName)) == null) { > return false; > } > // In order to mantain consistency, when possible we delete the last > '/' character in the String > int indexOfSlash=fullName.lastIndexOf('/'); > String parentFullName; > if (indexOfSlash==0){ > parentFullName="/"; > } > else{ > parentFullName=fullName.substring(0,indexOfSlash); > } > > // we check if the parent FileObject is writable. > NativeFileObject parentObject=new > NativeFileObject(parentFullName,file.getAbsoluteFile().getParentFile(),user); > return parentObject.hasWritePermission(); > } > -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
