Hello everybody,
I'm using Lucene.Net with my own implementation of Directory which stores the
files in the SQL database.
Additionally, it maintains the reference count for the locks created in the
directory. One thing I noticed is
that there are locks left behind sometimes. Eventually, I tracked the problem
down to SegmentReader.
The trouble that I see with SegmentReader (and TermInfosReader as well) is that
it stores references
to TermVectorsReader in ThreadLocalStore when GetTermVectorsReader is called,
but .Close method fails
to close and clean up that reference.
The change that I've implemented in my local copy of Lucene (and which seems to
work) is like this - I added
the following code to the beginning of DoClose in SegmentReader:
TermVectorsReader tvReader = (TermVectorsReader)
System.Threading.Thread.GetData(termVectorsLocal);
if (tvReader != null)
{
tvReader.Close();
System.Threading.Thread.SetData(termVectorsLocal, null);
}
The following change has been done to TermInfosReader:
SegmentTermEnum termEnum = (SegmentTermEnum)
System.Threading.Thread.GetData(enumerators);
if (termEnum != null)
{
termEnum.Close();
System.Threading.Thread.SetData(enumerators, null);
}
Regards,
Volodymyr.
