Comment 1 for bug 1523685

Customer noted (adapted to the example above):

"I did a brief look at the source, the problem lies in:

foreach my $method ( @$methods ) {
die "Invalid recursion method: " . ($method || 'undef') . "\n"
unless $method && $method =~ m/^(?:processlist$|hosts$|none$|cluster|dsn=)/i;
}

the method somehow is "dsn=D=percona", "t=dsns", and the second one does not pass the test. There is one dsn method which is "dsn=D=percona,t=dsns", somehow the comma is interpreted as the separation of two DSN methods."
