[Hibernate-JIRA] Created: (ANN-598) Add ON clause to @ForeignKey

by Christian Bauer (JIRA)

Add ON clause to @ForeignKey ---------------------------- Key: ANN-598 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-598 Project: Hibernate Annotations Issue Type: New Feature Components: binder Reporter: Christian Bauer More important than it sounds: @org.hibernate.annotations.ForeignKey(name = "FK_FEED_DIRECTORY_ID") I need ON CASCADE DELETE on many of my foreign keys, so I have to do this right now via: <hibernate-mapping> <database-object> <create> alter table FEED drop constraint FK_FEED_DIRECTORY_ID; alter table FEED add constraint FK_FEED_DIRECTORY_ID foreign key (DIRECTORY_ID) references NODE on delete cascade; </create> <drop></drop> </database-object> </hibernate-mapping> This is a bit annoying, especially since @JoinColumn(columnDefinition) is also not an option - I don't want to hardcode my HSQL datatypes. So we should accept a parameter on @ForeignKey (I know that the Hibernate binder doesn't have that notion at all, we need it in native Hibernate as well) that accepts "[ON {DELETE | UPDATE} {CASCADE | SET DEFAULT | SET NULL}];" and does the right thing during schema export. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2766) many-to-one with property-ref run into an recursive issue

by René Fuchs (JIRA)

many-to-one with property-ref run into an recursive issue --------------------------------------------------------- Key: HHH-2766 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2766 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Hibernate 3.2.5, Informix 10 Reporter: René Fuchs With many-to-one and property-ref, hibernate resolve always the whole referenced entity. So we have alway an eager issue. If the resolved entity includes one or more other references to non primary keys, these entities will be also resolved and so on. In a big legacy database, if I read only one entity, I get 100 selects or a very very long joined sql (fetch="join"). I think the problem ist located in: org.hibernate.type.EntityType public Object resolve(Object obj, SessionImplementor sessionimplementor, Object obj1) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2882) QueryKey.equals() returning false with distributed caching

by Daniel Campagnoli (JIRA)

QueryKey.equals() returning false with distributed caching ---------------------------------------------------------- Key: HHH-2882 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2882 Project: Hibernate3 Issue Type: Bug Components: query-criteria Affects Versions: 3.2.5 Reporter: Daniel Campagnoli We noticed some issues recently with the query cache when using Coherence as the cache provider. This was due to instances of org.hibernate.cache.QueryKey not being equal after being serialized then deserialized. The equals check was failing on the [ResultTransformer customTransformer] field which in our case had an instance of RootEntityResultTransformer (which comes from the field CriteriaSpecification.ROOT_ENTITY). This is because RootEntityResultTransformer doesnt override equals, so the check is done by reference equality. When the QueryKey has been serialized and deserialized out of the cache, the instance will always be different, so the equals check will fail. A fix for this to be implement equals for RootEntityResultTransformer (and possibly the other ResultTransformer's). I used the following which worked fine. public boolean equals(Object obj) { return obj != null && this.getClass() == obj.getClass(); } ps. I created HHH-1665 a while ago, a real simple fix, could that be looked at :) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (ANN-554) NPE with @Id on @OneToOne

by Loïc Minier (JIRA)

NPE with @Id on @OneToOne ------------------------- Key: ANN-554 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-554 Project: Hibernate Annotations Type: Bug Versions: 3.2.1 Environment: Hibernate 3.2.2 GA, Hibernate Annotations 3.2.1, J2SE 1.6.0-b105 on Debian GNU/Linux sid, PostgreSQL 7.4 Reporter: Loïc Minier Priority: Minor Hi, (Note: I originally reported this on the forum, but the lack of response suggests this might be a bug in Hibernate Annotations or Hibernate; the forum topic is at: http://forum.hibernate.org/viewtopic.php?t=970823) I hope it's not a misuse of Hibernate, but I'm trying to use @Id on @OneToOne, and this causes the following NPE when running hbm2ddl: java.lang.NullPointerException at org.hibernate.util.StringHelper.qualify(StringHelper.java:264) at org.hibernate.cfg.OneToOneSecondPass.doSecondPass(OneToOneSecondPass.java:196) at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1130) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:296) at org.hibernate.cfg.Configuration.buildMappings(Configuration.java:1115) at org.hibernate.tool.ant.ConfigurationTask.getConfiguration(ConfigurationTask.java:56) at org.hibernate.tool.ant.HibernateToolTask.getConfiguration(HibernateToolTask.java:287) at org.hibernate.tool.ant.Hbm2DDLExporterTask.execute(Hbm2DDLExporterTask.java:45) at org.hibernate.tool.ant.HibernateToolTask.execute(HibernateToolTask.java:171) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275) at org.apache.tools.ant.Task.perform(Task.java:364) at org.apache.tools.ant.Target.execute(Target.java:341) at org.apache.tools.ant.Target.performTasks(Target.java:369) at org.apache.tools.ant.Project.executeSortedTargets(Project.java:1216) at org.apache.tools.ant.Project.executeTarget(Project.java:1185) at org.apache.tools.ant.helper.DefaultExecutor.executeTargets(DefaultExecutor.java:40) at org.apache.tools.ant.Project.executeTargets(Project.java:1068) at org.apache.tools.ant.Main.runBuild(Main.java:668) at org.apache.tools.ant.Main.startAnt(Main.java:187) at org.apache.tools.ant.launch.Launcher.run(Launcher.java:246) at org.apache.tools.ant.launch.Launcher.main(Launcher.java:67) What I'm trying to do at the application level is: Foo class and table long foo_id, primary key FooData fooData, nulllable=true FooData class and table foo_id references Foo(foo_id), nullable=false This is expressed in Java as: @Entity @Table(name = "foo") public class Foo { @Id @GeneratedValue @Column(name = "foo_id") Long id; @OneToOne(mappedBy = "foo", cascade = CascadeType.ALL) FooData fooData; ... @Entity @Table(name = "foo_data") public class FooData { @Id @OneToOne @JoinColumn(name = "foo_id", nullable = false) Foo foo; This causes a NPE here. If I use a real Id on FooData, e.g.: @Id @Column(name = "foo_data_id") Long id; it works, and I end up with: - foo_id in table foo as a primary key - foo_data_id in table foo_data as a primary key - foo_id in table foo_data not null - foo_id in table foo_data references foo_id in table foo I don't want a foo_data_id, I don't need it, hence the lack of it which leads to the NPE.

[Hibernate-JIRA] Created: (HHH-2669) Unequivocally map MySQL LOB types to the LONG variant

by Steve Ebersole (JIRA)

Unequivocally map MySQL LOB types to the LONG variant ----------------------------------------------------- Key: HHH-2669 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2669 Project: Hibernate3 Issue Type: Improvement Components: core Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.3 MySQL differentiates different "sizes" of LOBs. Apparently, the smaller types offer no storage benefit nor performance gain. So we should consider mapping the LOB types in the MySQL dialect to the LON variants in all cases. The current setup causes truncation headaches for users, apparently unnecessarily. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2782) Component getType caches the type value

by Kiss Zoltán (JIRA)

Component getType caches the type value --------------------------------------- Key: HHH-2782 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2782 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: all Reporter: Kiss Zoltán Component class caches the value of the type attribute: public Type getType() throws MappingException { // added this caching as I noticed that getType() is being called multiple times... if ( type == null ) { type = buildType(); } return type; } This forbids the use of 'dynamic attributes'. For eg. if you try to add new properties to an existing dynamic-component with the addProperty method, then the rebuild of the session factory will failed, because the Component property will be invalid during the validation (in the Component there will be a different column span value, then in the cached ComponentType). There should be a method like this in the Component class: public void rebuildType() { type = buildType(); } With the help of this the type could be rebuild if it is necessary. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2112) ClassCastException in StatefulPersistenceContext.getCachedDatabaseSnapshot(...)

by Aleksei Valikov (JIRA)

ClassCastException in StatefulPersistenceContext.getCachedDatabaseSnapshot(...) ------------------------------------------------------------------------------- Key: HHH-2112 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2112 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr4 Reporter: Aleksei Valikov StatefulPersistenceContext.getCachedDatabaseSnapshot(EntityKey key) causes ClassCastException when NO_ROW was put for the certain entity key. Please see the discussion here: http://forum.hibernate.org/viewtopic.php?t=959868&highlight=getcacheddata... In these situations, this method should probably return null.
