Hello Monks!

I have a script (several actually) that is run through Mod_Perl/Apache Registry and there seems to be variable sharing/leaking going on.

Without further ado here's the essence of the script...

=========================
shebang, initialization ... "do" etc.

&main()

sub main
{
        my $cgi = CGI->new();
        my %params = $cgi->Vars();

        # Get the MAC address from the URL.
        my $id             = $params{id};

        my $sqlStmt;
        my $hStmt;

        my $hDb = AnotherModule::connectDb();

        $sqlStmt = "SELECT several rows";

        $hStmt = MyModule::execSql($hDb, $sqlStmt);
        my ($value1, $value2, $value3);

        my $list = "";

        while ($value1, $value2, $value3) = $hStmt->fetchrow) {
              $list .= "$value1,$value2,$value3;";
         }

        print "$list";

        OtherModule::log($blah, $blah, "$list");

        $hStmt->finish;
        $hDb->disconnect;

        exit(0);
}

I know that the first comment will be about the SQL stuff not being done the official way -- and you're be right, but there doesn't appear to be an issue with that.

The issue is that $list is sometimes correct, and other times has values appended to it that are from "another thread". Using DBI persistent connections.

It appears as though this may be the issue: http://perl.apache.org/docs/general/perl_reference/perl_reference.html#my____Scoped_Variable_in_Nested_Subroutines

I've read it, but don't understand it. I've tried changing "my" to "our local", no luck.

Any recommendations on how to solve this quickly and easily are really appreciated!
