[Bug inetlib/30118] New: Bug in gnu inetlib nntp LineIterator

[mikkotommila at netscape dot net]

I think I have found a bug in the gnu.inet.nntp.LineIterator class. It seems to
get occasionally stuck in an infinite loop in the readToEOF() method.

Looking at the code it seems like this is possible because readToEOF() calls
doRead() without resetting the doneRead flag.

The bug can be reproduced e.g. with this simple test class (change the news
server name to some valid server):

import java.io.IOException;
import gnu.inet.nntp.LineIterator;
import gnu.inet.nntp.NNTPConnection;

public class Test
{
    public static void main(String[] args)
        throws IOException
    {
        NNTPConnection connection = new NNTPConnection("news.server.com");
        connection.help();
        connection.group("alt.test");
        connection.quit();
    }
}

I think it could be fixed by changing readToEOF() to:

  public void readToEOF()
    throws IOException
  {
    doRead();
    while (current != null)
      {
        doneRead = false;
        doRead();
      }
  }
