I have disabled audits and branches. In some cases, when deleting an object the revision number is set to a negative number instead of deleting it permanently. In other cases it is just deleted as expected. I will try to create a scenario to reproduce this...
I can confirm this behaviour but in my case it seems to always happen. In the configuration I set <property name="supportingAudits" value="false"/> Using CDO 4.0 (Indigo Release)
For me, it works when the object is not contained directly in the CDOResource.
I can also confirm that the nonaudit class mapping does not delete the row from the attribute table. (see detachAttributes() in HorizontalNonAuditClassMapping). All many references are removed correctly. In addition this object is also not deleted from the CDO_OBJECTS table.
Moving all open issues to 4.2. Open bugs can be ported to 4.1 maintenance after they've been fixed in master.
Hi Eike, I am willing to sponsor this fix. rgds Christophe
Sounds great ;-) Will we meet at the EclipseCon to discuss this?
Turning back into a problem so that the fix can be applied to maintenance, too.
This fix comes with a new feature: an automatic schema migration mechanism. It detects code updates and migrates (the database of) an existing instance automatically. Please note that we consider all schema changes like API changes and, even if compatible, we can't silently apply them to maintenance. This also makes the schema versioning itself magnitudes simpler (a linear version chain is enough, instead of a two dimensional matrix of migration rules). That means you'll either have to upgrade to a new I-build (CDO 4.2) or apply the changes to an older repository yourself. commit d3fd5cce836a3542504238bf953d53c554b0c52d

(In reply to comment #16) > Created attachment 223531 [details] > getMinLocalID > > SQL Query alias not allowed in MIN MySQL function. This confuses me. You don't seem to remove the alias as such. Is this really just a problem of the double quotes that I added for Oracle?
I've removed ALL double quotes around alias names via bug 393111.
Strange that noone ever complained about getMinLocalID() not working in non-branching mode! Everybody must be using branching mode or be eager to always shutdown properly :P The concept of "local IDs" is meaningless in non-branching mode. So I guarded the call to getMinLocalID() as follows: if (repository.isSupportingBranches()) { CDOID minLocalID = getMinLocalID(connection); idHandler.setNextLocalObjectID(minLocalID); } commit c734ed318fff4aa6530e84530bb528010eae562f
*** Bug 394207 has been marked as a duplicate of this bug. ***
My explanation was not correct, what MySQL complains about is the quoted alias in the MIN function, so removing them as in the attached patch did the trick.
perhaps it's a different bug, but a proper shutdown on my side. (typing shutdown in the osgi console) , still goes into crash recovery mode the next time I start the server. Perhaps I need to clean-up some CDO stuff in a osgi stop() bundle?
(In reply to comment #24) > perhaps it's a different bug, but a proper shutdown on my side. (typing > shutdown in the osgi console) Hmm, I always use "close". Can you please try that instead?
with 'close' CDO starts normally, the next run, without going into crash detect
Excellent ;-)
I have just tried this out with CDO 4.2 from http://download.eclipse.org/modeling/emf/cdo/drops/S20121114-1534 I"m currently running EMF 2.8.1 and I keep getting an IllegalAccessError (Stacktrace below). I guess this means I will need an I build of EMF 2.9? Is there any chance this fix makes it into 4.1 maintainance? Exception in thread "CDOInvalidationRunner-View 1" java.lang.IllegalAccessError: tried to access method org.eclipse.emf.ecore.impl.ENotificationImpl.<init>(Lorg/eclipse/emf/ecore/InternalEObject;ILorg/eclipse/emf/ecore/EStructuralFeature;II)V from class org.eclipse.emf.internal.cdo.object.CDODeltaNotificationImpl at org.eclipse.emf.internal.cdo.object.CDODeltaNotificationImpl.<init>(CDODeltaNotificationImpl.java:83) at org.eclipse.emf.internal.cdo.object.CDONotificationBuilder.createNotification(CDONotificationBuilder.java:292) at org.eclipse.emf.internal.cdo.object.CDONotificationBuilder.visit(CDONotificationBuilder.java:164) at org.eclipse.emf.cdo.internal.common.revision.delta.CDOSetFeatureDeltaImpl.accept(CDOSetFeatureDeltaImpl.java:69) at org.eclipse.emf.cdo.internal.common.revision.delta.CDORevisionDeltaImpl.accept(CDORevisionDeltaImpl.java:309) at org.eclipse.emf.internal.cdo.object.CDONotificationBuilder.buildNotification(CDONotificationBuilder.java:88) at org.eclipse.emf.internal.cdo.view.CDOViewImpl.sendDeltaNotifications(CDOViewImpl.java:977) at org.eclipse.emf.internal.cdo.view.CDOViewImpl.doInvalidate(CDOViewImpl.java:857) at org.eclipse.emf.internal.cdo.view.CDOViewImpl$InvalidationRunnable.run(CDOViewImpl.java:1591) at org.eclipse.net4j.util.concurrent.QueueRunner.work(QueueRunner.java:26) at org.eclipse.net4j.util.concurrent.QueueRunner.work(QueueRunner.java:1) at org.eclipse.net4j.util.concurrent.QueueWorker.doWork(QueueWorker.java:88) at org.eclipse.net4j.util.concurrent.QueueWorker.work(QueueWorker.java:79) at org.eclipse.net4j.util.concurrent.Worker$WorkerThread.run(Worker.java:206)
Oh, I was not aware that I accidentally started to use EMF 2.9 specific API. I'll investigate alternatives...
