Re: [hibernate-dev] Snapshot conflict with merge
I confirm what I said. I added a testcase to HEM. Here is the most accurate thing I can find from the spec 3.4.2 Version Attributes [...] The persistence provider's implementation of the merge operation must examine the version attribute when an entity is being merged and throw an OptimisticLockException if it is discovered that the object being merged is a stale copy of the entity—i.e. that the entity has been updated since the entity became detached. Depending on the implementation strategy used, it is possible that this exception may not be thrown until flush is called or commit time, whichever happens first. [...] Christian Bauer wrote: [hibernate-dev] Snapshot conflict with merge I wrote (tested and verified with Gavin): Finally, merging doesn’t allow the following scenario, where two modifications conflict on one snapshot: item.getId() // The database identity is "1234" item.setDescription(...); Session session= sessionFactory.openSession(); Transaction tx = session.beginTransaction(); Item item2 = (Item) session.get(Item.class, new Long(1234)); item2.setDescription(...); // Not allowed! return session.merge(item); // Throws exception! tx.commit(); session.close(); The detached object’s description is modified as well as the persistent object’s. There is no way for Hibernate to determine who will win in this situation and a StaleObjectStateException is thrown when you try to merge() onto a dirty persistent instance. Emmanuel comments: No exception is raised in my tests. The merged state takes precedence over the initially loaded and modified state (regardless the object has been versioned or not) AFAIR, the spec does not talk about such an exception either.

you mean a standard version of optimistick-lock="false"? Christian Bauer wrote: On Sep 26, 2006, at 10:20 PM, Emmanuel Bernard wrote: I confirm what I said. I added a testcase to HEM.

By the way, another major thing missing in the spec is standardized version increment checking, that is, which properties have to be dirty for a version increment to happen.

[hibernate-dev] batch-size algorithm
Currently we create several loaders following a certain algorithm Why don't we create a single loader of batch-size and duplicate ids in the in clause to match unfilled parameters batch-size = 20 uninitialized proxies 17 current algorithm select * from Table where id in (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) select * from Table where id in (11, 12, 13, 14, 15, 16, 17) current algorithm select * from Table where id in (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 17, 17, 17) This would reduce the memory footprint and reduce the prepared statement pool needed This case is a sample but it shines when people set up a batch-size of 100 since the number of queries triggered can drop from 5 to 1 query for 98 uninitialized proxies ___ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
