In 5.0 we made LOAD DATA INFILE autocommit in all engines, while only NDB wanted that. Users and trainers complained that it affected InnoDB and was a change compared to 4.1 where only NDB autocommitted. To revert to the behaviour of 4.1, we move the autocommit logic out of mysql_load() into ha_ndbcluster::external_lock(). The result is that LOAD DATA INFILE commits all uncommitted changes of NDB if this is an NDB table, its own changes if this is an NDB table, but does not affect other engines. Note: even though there is no "commit the full transaction at end" anymore, LOAD DATA INFILE stays disabled in routines (re-entrency problems per a comment of Pem). Note: ha_ndbcluster::has_transactions() does not give reliable results because it says "yes" even if transactions are disabled in this engine...
