[DDC-2515] Schema tool ignores index names in mapping file and uses generated name Created: 18/Jun/13  Updated: 21/Jun/13

I have defined an index on a foreign key colum in my .dcm.xml mapping file:

      <index name="ix_date_created__client_id" columns="date_created,client_id"/>
      <index name="ix_user_id" columns="user_id"/>

However, the resulting CREATE TABLE statement includes:

    INDEX IDX_4848DD9FA76ED395 (user_id), 
    INDEX IDX_4848DD9F4239E22F (accessgroup_id), 
    INDEX IDX_4848DD9FD2112630 (usergroup_id), 
    INDEX ix_date_created__client_id (date_created, client_id), 

So Doctrine seems to be auto-generating indexes for all foreign key columns. I'm assuming this is a feature, even though I'd argue that there are real-life examples where the mere presence of a foreign key constraint does not justify indexing that column.

Anyway, the expected behavior is that Doctrine does not replace existing indexes with generated ones. I will attach a failing test case unless this bug is immediately dismissed as wontfix.
