[Hibernate-JIRA] Created: (HHH-2146) NullpointerException in DefaultDeleteEventListener.deleteTransientEntity
by Martin Kartumovich (JIRA)
NullpointerException in DefaultDeleteEventListener.deleteTransientEntity
------------------------------------------------------------------------
Key: HHH-2146
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2146
Project: Hibernate3
Type: Bug
Versions: 3.2.0.cr5
Environment: Hibernate 3.2.0cr5, Oracle10g
Reporter: Martin Kartumovich
Priority: Blocker
The following setup leads to a NPE in DefaultDeleteEventListener.deleteTransientEntity:
Tables A, B
Table V_A_B that is an M-N-Connection between A and B.
Pojo for A has a Set of V_A_Bs.
Pojo for B has a Set of V_A_Bs.
Pojo C that has Sets of As and Bs.
Cascades: all, delete-orphan
-Create a new A and add a new V_A_B to its Set, that references to an existing B.
-Delete B.
-SaveOrUpdate Pojo C.
In Hibernate 3.1.3 this works fine.
In 3.2.0cr4+cr5 the removal of B results into an cascading removal of the never persisted V_A_B in the Set of B instead of ignoring it.
This leads to an incorrect state where deleteTransientEntity is called with transientEnties=null.
When now calling transientEnties.contains(...) the NPE is thrown.

[Hibernate-JIRA] Created: (ANN-841) Bidirectional indexed collection mapped incorrectly for IndexedCollectionTest
by Gail Badner (JIRA)
Bidirectional indexed collection mapped incorrectly for IndexedCollectionTest
-----------------------------------------------------------------------------
Key: ANN-841
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-841
Project: Hibernate Annotations
Issue Type: Bug
Reporter: Gail Badner
Assignee: Emmanuel Bernard
Attachments: TEST-org.hibernate.test.annotations.indexcoll.IndexedCollectionTest.xml
I believe that two bidirectional associations with indexed collections that use join tables are mis-mapped for org.hibernate.test.annotations.indexcoll.IndexedCollectionTest.
Mappings in AddressBook:
@MapKey
@OneToMany(mappedBy = "book", cascade = {CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REMOVE})
@JoinTable(name="AddRegEntry")
public Map<AddressEntryPk, AddressEntry> getEntries() {
return entries;
}
@MapKey(name = "directory")
@OneToMany(mappedBy = "book")
@JoinTable(name="Dir_Entry")
public Map<AlphabeticalDirectory, AddressEntry> getDirectoryEntries() {
return directoryEntries;
}
Mappings in AddressEntry:
@ManyToOne
public AddressBook getBook() {
return book;
}
@ManyToOne
public AlphabeticalDirectory getDirectory() {
return directory;
}
AddRegEntry and Dir_Entry are not generated in the DDL and the CRUD operations do not reference the join tables.
Test output is attached.

[Hibernate-JIRA] Created: (HHH-2399) FlushMode.AUTO practically unusable - should not flush before EVERY query
by Piotr Kołaczkowski (JIRA)
FlushMode.AUTO practically unusable - should not flush before EVERY query
-------------------------------------------------------------------------
Key: HHH-2399
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2399
Project: Hibernate3
Type: Improvement
Versions: 3.1.3, 3.2.1, 3.2.2, 3.2.0.ga
Environment: PostgreSQL 8.1.5, JDBC 2 and 3, Linux kernel 2.4.x, 2.6.x, Java 1.5.0_09
Reporter: Piotr Kołaczkowski
Attachments: hbtest.zip
The method flushIfRequired seems to flush before every query execution, even though there wasn't anything changed to the objects in the session, and the objects in the session are of different class than the object(s) queried. When having more than a few such objects in a session, it may lead to large, unneeded overheads (I noticed 10-200 times slowdown on simple queries). Our system uses many fast queries, that uasually return only one result or few results. The average query durations on different levels, measured by System.nanoTime() (see the attachment):
- database level: 0.05 ms
- pure JDBC code, prepared statements: 0.2 ms
- pure JDBC code, no prepared statements: 0.7 ms
- not cached hibernate query, no other objects associated with the session: 1.3 ms
- cached hibernate query, object in the session cache, no other objects associated with the session: 1.1 ms
- cached hibernate query, 10000 very simple objects of some other class in the session: >50 ms
10000 may seem large, but note these were very simple objects, having only 2 properties. On our production system we have classes with many properties, and even 20 objects in a session can cause a sub-millisecond query to run longer than 5 ms. We switched to FlushMode.COMMIT, and now the performance is much better.
Can you do something about this? As far as I've read in JIRA, a similar issue exists in Hibernate 2.x, and is still OPEN / UNRESOLVED.
BTW. Why is the 1st level cache so slow in my tests? Why reading just a 2 field object from the database cause so much overhead over pure JDBC? What am I doing wrong?
There is so much marketing about using cglib reflection optimizer in the performance FAQ but even if I retrieved these objects using JDBC and reflection, I would achieve much better performance. After all 1 ms is very much time, if getting results from DB and sending them to JVM lasts 0.2 ms.

[Hibernate-JIRA] Created: (HHH-2347) Improvement to DerbyDialect default identy generation mode
by Fabrizio Giustina (JIRA)
Improvement to DerbyDialect default identy generation mode
----------------------------------------------------------
Key: HHH-2347
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2347
Project: Hibernate3
Type: Patch
Versions: 3.2.1
Reporter: Fabrizio Giustina
Attachments: DerbyDialect-identity.diff
although derby supports identities org.hibernate.dialect.DerbyDialect strangely uses an HiLo generation strategy for ids (for any other dialects that support identities IdentityGenerator is the default).
Even more curiously, DerbyDialect overrides getIdentityColumnString() from the Db2 dialect by using "generated ALWAYS as identity" instead of "generated BY DEFAULT as identity". Derby however fully supports "by default" in identities as clarified in http://db.apache.org/derby/docs/10.1/ref/rrefsqlj37836.html .
"by default" should be preferred since it allows a direct insertion when needed (and I can't see no reason why enabling it for db2 and not for derby).
The patch attached simply deletes two methods, so that the default implementation from Db2Dialect is used:
- removing getIdentityColumnString() make derby use "by default" identities like db2 already does
- removing getNativeIdentifierGeneratorClass() make it choose IdentityGenerator.class (it falls back to the default strategy used in org.hibernate.dialect.Dialect)
note that part of this issue has already been reported in HHH-1918 (not addressing the identity generation string)
