Quick question about PostCommitInsertEventListener
by Haswell, Josiah D
Hi folks,
In Datomic, when you create an entity, you must give the entity a temporary ID before you insert it. After the transaction completes, each entity in the transaction is given an actual persistence ID back from the database. My initial approach was to generate the temporary identifier in the createTuple method of the IdentityColumnAwareGridDialect, and provide a customer persister implementation to handle it. It occurred to me that it might be easier to just use a listener. After a bit of fiddling around, I discovered that PostCommitInsertEventListener can (apparently) substitute out the ID at what appears to be the correct location. From what I can tell, this both simplifies the code, and the generated ID seems to be propagated to everything correctly. Is the custom persister the preferred way to do this? Or should this work? Is there a better place to perform that substitution?
Thanks!

EntityManagetFactory unwrap - HHH-9665
by Hardy Ferentschik
Hi there,
Steve and I are having a discussion around the intended behavior of EntityManagerFactory#unwrap.
See also HHH-9665[1] and the corresponding pull request [2].
At the moment the implementation in EntityManagerFactoryImpl allows to unwrap into the implementation
class itself. This way the user gets a reference to an internal class. IMO there should be instead a
public interface which the user can unwrap to, eg HibernateEntityManagerFactory. This interface hosts
additional methods we want to expose on top of the HibernateEntityManagerFactory. The unwrapping to
should be disallowed (by expception) in this case. IMO this is just a continuation of the whole
idea of splitting packages between public, spi and internal. Of course this cannot stop a user from
doing an explicit cast, but that's a different story imo.
Steve and I have different take on this issue, so we where wondering what others think?

[Validator] Build problems!?
by Hardy Ferentschik
Hi,
I seem to have a odd build problem and wondering whether someone could verify the problem
or in any ways enlighten me regarding what's going on.
I can build the Validator master branch w/o problem ('mvn clean install'), but a 'mvn deploy' (SNAPSHOT deploy)
fails (output below). The funny thing is that the failure seems to occur during the main
compilation task which seems odd, since the classes compile fine when using the 'install' target.
It might be related to the fact that a 'deploy' enables different profiles/settings, but a start
would be to figure out whether others have the same problem.
-- Hardy
P.S.: The Cloudbees HV-5.2-SNAPSHOT-DEPLOY job recently also fails erratically. It might be the same problem.

HHH-9701 - Develop "immutable EntityEntry" impl
by John O'Hara
Steve,
I have pushed a proposal for HHH-9701 to:
https://github.com/johnaoahra80/hibernate-orm/tree/HHH-9701
There are a couple of areas that I would appreciate feedback;
1) Serialization/Deserialization - EntityEntries implementations can be
serialized and each implementation provide their own serialization
method. I have modified the serialization of EntityEntry in
EntityEntryContext to write the Implementation class to the OutputStream
so the correct class can be used to deserialize the object stream. Is
the exception handling sufficient here, or do we need more robust
handling of deserialization exceptions? : see
https://github.com/johnaoahra80/hibernate-orm/commit/ec9b1fa3b97131ff1e65...
2) In our (perf team) use case, we want to be able to share the
ImmutableEntityEntry between sessions when they are referenced cached in
the 2lc. I have modified EntityEntryContext to not null
managedEntity.$$_hibernate_setEntityEntry if the EntityEntry is an
instance of ImmutableEntityEntry. Do we need to add an extra checks
here, to ensure that the entity is Reference Cached? I am not sure how
we would test that case? : see
https://github.com/johnaoahra80/hibernate-orm/commit/ec9b1fa3b97131ff1e65...
3) Lock Mode: Steve you mentioned about not doing locking for Immutable
entities. Where is the locking implemented? Would it be sufficient to
simply set the LockMode on the ImmutableEntityEntry to NONE/READ_ONLY
when setLockMode is called?
Thanks
John

OGM test refactoring
by Jonathan Halliday
In the course of developing the cassandra backend for OGM I've hit an
issue with some of the backendtck tests.
These tests are in core and reused by each backend. It's possible to
exclude tests at class or method level per backend, which prevents
irrelevant tests from running for a given backend. So far, so good.
The problem I'm seeing stems from the fact that even when a test is
excluded, the annotated POJOs it uses are still parsed and passed
through schema creation, since that occurs in a setup step before the
individual tests are iterated and (not) run.
There are certain POJOs that contains mappings cassandra can't support.
Even with the corresponding test disabled, when these are passed to the
schema creator it blows up, effectively preventing the other legitimate
tests in the same class from running.
In an ideal world I'd like a class/method level annotation listing the
required POJOs to replace the getAnnotatedClasses method, allowing POJOs
to be parsed or skipped in accordance with the corresponding annotation
on the same test method.
@RequiredPOJO(Foo.class)
@Test
@SkipByGridDialect(...)
public void testFoo()
Alternatively I can (I think) subclass the test class in the backend and
override the getAnnotatedClasses method to exclude the problem POJOs,
whilst leaving the @SkipByGridDialect on the shared parent for clarity.
Or simply copy and paste the whole thing and nuke the offending
POJOs/methods in my backend's copy.
On a related note, many of the offending tests could be altered in such
a way that the resulting schema is acceptable to cassandra, which would
largely sidestep the issue but alter the test semantics. In many
instances I suspect the semantic in question is one that's not critical
to the test's intent, but I may be wrong.
Essentially cassandra uses what a relational db would call 'index
organized tables', i.e. the on-disk layout of data is a function of the
table's key. As a result, it's not possible to declare tables without a
primary key. Such mappings result from collections with bag semantics,
such as @OneToMany List<Object>, since the list may have dups. Removing
the bag semantics such as by adding an index column, avoids this issue.
But then you're testing something different...
Any preference on the approach to changing the test suite?
Jonathan.

Adding a custom table to the user defined mapping
by Sanne Grinovero
Hi all,
I'm considering solving a complex issue in Hibernate Search by having
it add a couple of "system entities" to the set of user defined
entities.
Do we have any example on how I'd do that?
Bonus brownies if we could figure out a way to mark these as
"internal".. i.e. it would be nice to not allow user code to load
these, have other entities relate to these, or mention them in HQL
queries.
I'd need a backdoor to allow Search code to do that though :)
Of course I don't expect us to be able to hide the physical tables.
I guess I could get pretty far by using JDBC rather than defining it
as an entity, but I'd rather avoid that. If that were my only option,
I'd at least want to extend the schema generation/validation tasks to
include by custom table.
Thanks,
Sanne
