Description:
------------
When the mysqlnd driver is used PDOStatement->nextRowset() does not return
bool(false) when there are no more result sets. This causes several test
failures, which all have a diff looking similar to this:
008+
009+ Warning: PDOStatement::fetchAll(): SQLSTATE[HY000]: General error in
%s/bug_41997.php on line 11
010+ array(0) {
011+ }
This can be traced down to mysql_next_result() returning 0 instead of -1 in
http://lxr.php.net/xref/PHP_TRUNK/ext/pdo_mysql/mysql_statement.c#415.
The reason is that (when using mysqlnd) mysql_next_result is aliased to
mysqlnd_next_result, but both have different APIs: The mysqlnd_ version only
returns PASS = 0 or FAIL = 1, whereas the mysql_ version returns -1 if the call
worked, but there were no more resultsets.
This is documented at
http://dev.mysql.com/doc/refman/5.0/en/mysql-next-result.html in the "Return
Values" section. The default mysqlnd next_result implementation is here:
http://lxr.php.net/xref/PHP_TRUNK/ext/mysqlnd/mysqlnd.c#2100.
