Use fewer transactions for updating InnoDB persistent statistics

    XMLWordPrintable

Details

    Description

      The function dict_stats_save() is problematic. If it ever goes to 'goto err' it will attempt to free an active transaction object, without trying to roll it back first.

      Furthermore, the first call to dict_stats_exec_sql() will use a different transaction object, that is, the update of table statistics is not a single atomic transaction with the update of index statistics.
