[Hibernate] Could someone please reopen HB-1390?
I just wanted to bring to the developer's attention that HB-1390 has not actually been applied to Hibernate 2, just Hibernate 3. The issue is erroneously marked as a duplicate. I know Hibernate 3 is the focus, but this is fix goes a long way towards making SchemaUpdate that much better working with Postgresql. http://opensource.atlassian.com/projects/hibernate/browse/HB-1390 Thanks, Patrick --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

This is a lot better than your original statements to the list. You were
originally quoting 1 second per object for transaction commit. Now you are
doing 1 in less than a second. Also, you would need to test to see how
long just the .beginTransaction() and .commit() methods are taking,
disregarding a dirty check. In other words, don't load any objects. Just do
the last part of your code and see what you get.

The problem is this: with 300-500 objects in the session cache, a single transaction( with an single object inserted) takes about one second. It simply does *not* take a second to dirty check 500 objects, dude. Nowhere even close. If you think you can prove that it does, send my the code to demonstrate this. It would have to be some kind of bug. I certainly agree. I have had 100,000 objects in a Collection (I am assuming internally Hibernate is doing about the same), and looped over them doing all sorts of math and creating new objects and that code took less than a half a second. There must be something else going on.

As having been one of those lothesome Jakarta committers, who has told so many people that if they want something fix/doc'd to fix/doc it, I really appreciate how much Max, Gavin, Christian, et al do. I think I my implicit idea was how much I appreciate how well Hibernate is documented. I have found only one place where the docs didn't live up to reality. (And I might even submit a patch to them to make it clearer) This implies you'd prefer people didn't donate source code unless they are prepared to doc it and meet other requirements. I would rather have the code in contention and then quickly dropped rather than never had that opportunity. I agree that value(docs) = value(code), so you try to help when you can. I agree that having the opportunity to have access to code with no docs is much better than that code having never been available. I greatly appreciate the contributions of the Jakarta projects and use them a lot in my personal projects. I just get very frustrated when there aren't docs or the docs are wrong. Cause then convincing my boss that we should use it becomes that much harder.

What can I say?
Thanks Sir for your valuable time.

prasad chandrasekaran
I sense great sarcasm there, but Christian's response is pretty good. If
you start a transaction and create a parent, then create children, and one
of the children fails, you rollback the transaction and the parent object
won't be created either. And that's not a Hibernate thing. That's a RDBMS
thing. Hibernate just provides a nice interface into it.
An example would be (Please excuse any syntax or API errors, doing this one
from memory):
try
{
Session session = SessionFactory.getSession();
Transaction tx = session.startTransaction();
Parent parent = new Parent();
set values of Parent
Child child = new Child();
set values of Child
parent.getChildren().add(child);
tx.commit();
}
catch(Exception e)
{
if( tx != null )
{
tx.rollback();
}
}
finally
{
session.close();
}
If you haven't already done so, I would look into a SQL book. I found the
following one quite helpful:
http://www.amazon.com/exec/obidos/tg/detail/-/0201703092/qid=1062203306/sr=8-3/ref=sr_8_3/103-7047765-0401466?v=glances=booksn=507846
