[jira] Created: (SANDBOX-331) CSVParser hangs (goes into infinite
loop) on getLine() if it's a "comment" line that doesn't contain a
delimiter
CSVParser hangs (goes into infinite loop) on getLine() if it's a "comment" line that doesn't contain a delimiter
----------------------------------------------------------------------------------------------------------------
Key: SANDBOX-331
URL: https://issues.apache.org/jira/browse/SANDBOX-331
Project: Commons Sandbox
Issue Type: Bug
Components: CSV
Reporter: Toli Kuznets
When you call CSVParser.getLine() or nextToken() with a line that is a comment as defined by the CSVStrategy but it doesn't contain the delimiter character, the call hangs in an infinite loop
This code will hang:
{code}
parser = new CSVParser(new StringReader("# abc\n"), new CSVStrategy('\t', '\'', '#'));
tokens = parser.getLine();
{code}
However, if you insert a delimiter char into the incoming string, it'll come through and return an empty string as a result:
{code}
CSVParser parser = new CSVParser(new StringReader("#\tabc"), new CSVStrategy('\t', '\'', '#'));
String[] tokens = parser.getLine();
System.out.println("result: "+Arrays.toString(tokens));
{code}
It gets stuck in an infinite loop in CSVParser.nextToken() in the loop around line 347
