Description
When I use dig trace for Test the apache dns server. the QuestionRecord and ResourceRecord not encoded right for the empty Domain Name.
my Test command is:
E:\bind>dig @10.108.20.126 618119.com +trace
Then found this bug is caeused by the method "encodeDomainName" in QuestionRecordEncoder.java and "putDomainName" in ResourceRecordEncoder.java.
follow code can be test to get "labels.length == 1";
[code]
String s = "";
String[] labels = new String[0];
labels = s.split("
.");
System.out.println("labels.length == " + labels.length);
[/code]
so i fix this bug by follow change :
[code]
String[] labels = domainName.split( "
." );
[/code]
change to:
[code]
String[] labels = new String[0];
if (domainName != null && domainName.length() > 0)
[/code]
Please fix the bug
