[CDO] really removing a DB record [message #943164]

Hi,

From the CDO API, how do I remove an object from the DB ? Currently a deleting an objects, sets the object revision a negative value, but keeps the DB record it in the DB. We use DBStore, and have auditing turned off.

Thank you, Christophe

Eike, are you there?
Could you please point me in the right direction for this question?
Is the behaviour CDOStore dependent?

It's a DBStore "bug":

351068: [DB] Consider deleting old revisions when audits disabled
https://bugs.eclipse.org/bugs/show_bug.cgi?id=351068

I really want to work on it soon.

Cheers

Thx Eike.
It seems in the bug, there are different observations.
In my case, I use this mapping:

<mappingStrategy type="horizontal"> 
<property name="qualifiedNames" value="true"/>
<property name="toManyReferences" value="ONE_TABLE_PER_REFERENCE"/>
<property name="toOneReferences" value="LIKE_ATTRIBUTES"/>

Does it make any difference for the bug?

IIRC this is a delegating mapping strategy that looks at the repository's auditin/branching mode and sets up a delegate
accordingly. You can check with a breakpoint in HorizontalMappingStrategy.doActivate().
