Subject [jira] Created: (SANDBOX-313) Endless loops in CSV parser
Date Mon, 21 Sep 2009 19:59:15 GMT
Endless loops in CSV parser
---------------------------

                 Key: SANDBOX-313
                 URL: https://issues.apache.org/jira/browse/SANDBOX-313
             Project: Commons Sandbox
          Issue Type: Bug
          Components: CSV
    Affects Versions: Nightly Builds
            Reporter: Bjoern Voigt


If the input file ends with comment lines, the parser runs into an endless loop. The example
shows, that the CSV parser runs into an endless loop, if the input is one comment line. '#'
is the comment character here:

{noformat}
import org.apache.commons.csv.CSVStrategy;
import org.apache.commons.csv.CSVParser;
import java.io.StringReader;
import java.io.IOException;

public class TestCSV {
    public static void main(String [] args) throws IOException {
        CSVStrategy strategy=new CSVStrategy(',','"','#','\\',false,false,false,false);
        
        CSVParser parser = new CSVParser(new StringReader("# A, B\n"), strategy);
        
        System.out.println("Go into an endless loop...");
        String []line=parser.getLine();
    }
}
{noformat}
