Traversal of directory tree with FileSelector fails with symbolic links in FTP
& SFTP
-------------------------------------------------------------------------------------
Key: VFS-179
URL: https://issues.apache.org/jira/browse/VFS-179
Project: Commons VFS
Issue Type: Bug
Reporter: Andrew Franklin
It seems to me that when using the FileSelector to traverse a directory tree
using SFTP, a symbolic link will return as type File (even when the link points
to a directory), which will result in the directory node not being followed.
For SFTP it seems that changing doGetType to explicitly deal with the link as
FILE_OR_FOLDER seems to fix the issue. I'm not sure whether this would have any
negative side effects...?
/**
* Determines the type of this file, returns null if the file does not
* exist.
*/
protected FileType doGetType() throws Exception
{
if (attrs == null)
{
statSelf();
}
if (attrs == null)
{
return FileType.IMAGINARY;
}
if ((attrs.getFlags() &
SftpATTRS.SSH_FILEXFER_ATTR_PERMISSIONS) == 0)
{
throw new FileSystemException(
"vfs.provider.sftp/unknown-permissions.error");
}
// A symbolic link might be a file or folder
if(attrs.isLink())
{
return FileType.FILE_OR_FOLDER;
}
else if (attrs.isDir())
{
return FileType.FOLDER;
}
else
{
return FileType.FILE;
}
}
