> Hi,
> the "hack" to keep track of files written to in FSDirectory, to filter them when calling
sync is heavily broken. [~mikemccand] already opened an issue, which was abandoned then.
> In fact handling this in FSDirectory is a hack and broken! If IndexWriter is itsself
not able to correctly handle tracking the files, it is also his repsonsibilty to do this.
We already have a class that can do this: TrackingDirectoryWrapper. IndexWriter should use
an instance of this class to track those stale files (until the problem is solved).
> I would like to keep FSDirectory clean from this, especially, as this is broken anyways:
If somebody has another directory impl like HDFS or Infinispan, the problem still persists.
The base directory should throw an IOException if trying to sync a file that does not exist!
