[Hibernate-JIRA] Created: (HHH-3414) fetch profiles

by Steve Ebersole (JIRA)

fetch profiles -------------- Key: HHH-3414 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3414 Project: Hibernate3 Issue Type: New Feature Components: core, metamodel Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.4 The concept of fetch profiles as we are discussing here is basically to allow users to dynamically affect the mapped fetching strategy for associations at runtime. Consider the following example: <class name="Person"> ... <set name="addresses" lazy="true" fetch="subselect" ...> ... </set> </class> <class name="Address"> ... </class> This follows the normal recommendation to map associations as lazy and use a dynamic fetching strategy (ala HQL/Criteria) to modify this lazy behavior at runtime. The fetaure discussed here would allow the same behavior for loading as well: <hibernate-mapping> <fetch-profile name="person-details"> <fetch path="Person.addresses" style="join"/> </fetch-profile> </hibernate-mapping> Or: <hibernate-mapping> <class name="Person"> ... <fetch-profile name="person-details"> <fetch path="addresses" style="join"/> </fetch-profile> <set name="addresses" lazy="true" fetch="subselect" ...> ... </set> </class> </hibernate-mapping> Now, doing: session.enableFetchProfile( "person-details" ).get( Person.class, 1 )... will load Person#1 as well as their addresses in a single joined query. -- 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

ManyToOne Persisting Cascade in Embeddable ------------------------------------------ Key: ANN-721 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-721 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.1.GA Environment: Java version: java version "1.6.0_04" Java(TM) SE Runtime Environment (build 1.6.0_04-b12) Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing) Oracle Version: Oracle9i Enterprise Edition Release 9.2.0.8.0 - Production PL/SQL Release 9.2.0.8.0 - Production "CORE 9.2.0.8.0 Production" TNS for Linux: Version 9.2.0.8.0 - Production NLSRTL Version 9.2.0.8.0 - Production hibernate: 3.2.6.ga hibernate-annotations: 3.3.1.ga hibernate-commons-annotations: 3.3.0.ga hibernate-entitymanager: 3.3.1.ga Reporter: Endre Jeges Attachments: pairTest.zip Hello, I have found something that is a bit strange. For @ManyToOne association properties in an @Embeddable class the cascade PERSIST, SAVE-UPDATE option is not working well (not sure for the other cascade types), if the entities associated with ManyToOne are transient. I have created a unit test to check it and I have it attached to this issue. It is a maven2 project, and needs Oracle to run it. If I save the associated entites, then everything works fine, also the data structure is created well. I have checked the forums and found similar problems, maybe they can help more then my post: http://forum.hibernate.org/viewtopic.php?t=965238 http://forum.hibernate.org/viewtopic.php?t=976534 http://forum.hibernate.org/viewtopic.php?t=978112 http://forum.hibernate.org/viewtopic.php?t=978138 http://forum.hibernate.org/viewtopic.php?t=983766 http://forum.hibernate.org/viewtopic.php?t=983780 http://forum.hibernate.org/viewtopic.php?t=983868 Details: @Entity class CodedPairHolder { @Id private Long id; @Column(name = "CODE", nullable = false, unique = true, updatable = false, length = 256) private String code; @CollectionOfElements @JoinTable(name = "CODED_PAIR_HOLDER_PAIR_SET", joinColumns = @JoinColumn(name = "CODED_PAIR_HOLDER_ID")) private final Set<PersonPair> pairs = new HashSet<PersonPair>(0); ........ constructors getters equals hashCode } @Embeddable class PersonPair { @ManyToOne(optional = false, fetch = FetchType.LAZY, cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }) @Cascade( { org.hibernate.annotations.CascadeType.PERSIST, org.hibernate.annotations.CascadeType.MERGE, org.hibernate.annotations.CascadeType.REFRESH, org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.REPLICATE, org.hibernate.annotations.CascadeType.EVICT }) @JoinColumn(name = "LEFT_PERSON_ID", nullable = false, updatable = false) private Person left; @ManyToOne(optional = false, fetch = FetchType.LAZY, cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }) @Cascade( { org.hibernate.annotations.CascadeType.PERSIST, org.hibernate.annotations.CascadeType.MERGE, org.hibernate.annotations.CascadeType.REFRESH, org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.REPLICATE, org.hibernate.annotations.CascadeType.EVICT }) @JoinColumn(name = "RIGHT_PERSON_ID", nullable = false, updatable = false) private Person right; ........ constructors getters equals hashCode } @Entity class Person { @Id private Long id; @Column(name = "NAME", nullable = false, unique = true, updatable = false, length = 256) private String name; ........ constructors getters equals hashCode } The error message is: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: Person Regards, jeges -- 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-3674) Expose SchemaUpdate#haltOnError as a configuration property

by Chris Bredesen (JIRA)

Expose SchemaUpdate#haltOnError as a configuration property ----------------------------------------------------------- Key: HHH-3674 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3674 Project: Hibernate Core Issue Type: New Feature Components: documentation, metamodel Reporter: Chris Bredesen Assignee: Chris Bredesen Priority: Minor SchemaUpdate currently collects and logs any Exceptions caught during its work. While the Exceptions are logged, Hibernate is allowed to startup successfully. This feature request allows for a setting to flip this behavior such that Hibernate will not start if one or more Exceptions are encountered during SchemaUpdate (in test environments, of course). Proposed configuration option is hibernate.hbm2ddl.haltOnError -- 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-5368) Not throwing Optimistic Lock when the entity is attached

by Fernando Rubbo (JIRA)

Not throwing Optimistic Lock when the entity is attached -------------------------------------------------------- Key: HHH-5368 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5368 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.4.sp1 Environment: windows XP, jboss 4.3 EAP, hibernate 3.4.2.sp1 Reporter: Fernando Rubbo Priority: Minor Hi Hibernate is not throwing Optimistic Lock when the entity is attached. It happens when the business rule sets a version in the attached entity that is less than its original (from database) version value. Take the following code as an example of the bug. // inserts A A a1 = new A(); a1.setName("A1"); dao.persist(a1); dao.flush(); dao.clear(); // as expected, the piece of code below works just fine final A a2 = dao.find(A.class, new BigDecimal(1)); a2.setName("A2"); dao.merge(a2); dao.flush(); dao.clear(); // as expected, this code fails due to Optimistic Lock try{ final A a3 = dao.find(A.class, new BigDecimal(1)); dao.clear(); a3.setName("A3"); a3.setVersion(0); //database verison is 1 dao.merge(a3); dao.flush(); Assert.fail(); }catch (Exception e) { System.out.println(e.getMessage()); // ignore }finally{ dao.clear(); } // unexpectedly, the piece of code below also works.. // even with the version being less than the one in the database // Note that this happens because hibernate is holding internaly the original version of the entity. // Even when the version is manually changed it keeps using the original one. final A a3 = dao.find(A.class, new BigDecimal(1)); a3.setName("A3"); a3.setVersion(0); //database verison is 1 dao.merge(a3); dao.flush(); dao.clear(); This problem can be handled by the business rule. For example, whether the version that comes from the screen is smaller than the one from the database it could throw an Optimistic Lock exception. However, it it was not handled, hibernate must take care of this in the same way it does with detached objects. -- 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-3967) Great performance improvement for CascadingAction.PERSIST_ON_FLUSH action !!

by Guenther Demetz (JIRA)

Great performance improvement for CascadingAction.PERSIST_ON_FLUSH action !! ---------------------------------------------------------------------------- Key: HHH-3967 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3967 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.3.1 Environment: 3.3.1 GA , SQLServer Reporter: Guenther Demetz Sometimes large stateful transactions are unavoidable and especially when having several large persistent collections in dirty state, flushing becomes gradually more cpu intensive and slowly. Analizing several stacktraces I detected that the thread most time is executing at the same point in reflection , see here a typical stacktrace: java.lang.Class.isAssignableFrom(Native Method) sun.reflect.UnsafeFieldAccessorImpl.ensureObj(UnsafeFieldAccessorImpl.java:36) ... java.lang.reflect.Field.get(Field.java:358) DirectPropertyAccessor$DirectGetter.get(DirectPropertyAccessor.java:55) PojoEntityTuplizer(AbstractEntityTuplizer).getPropertyValue(Object, int) line: 300 SingleTableEntityPersister(AbstractEntityPersister).getPropertyValue(Object, int, EntityMode) line: 3609 Cascade.cascade(EntityPersister, Object, Object) line: 172 ... Making further investigations, I saw that: - CascadingAction.PERSIST_ON_FLUSH requires NoCascadeChecking - for all kind of properties the noCascade implementation is called - regarding noCascade implementation checks only properties of type Entity ! public static final CascadingAction PERSIST_ON_FLUSH = new CascadingAction() { ... public void noCascade(EventSource session, Object child, Object parent, EntityPersister persister, int propertyIndex) { ... Type type = persister.getPropertyTypes()[propertyIndex]; if ( type.isEntityType() ) { ... check and throw eventually a TransientObjectException } } Thus most property values are retrieved by reflection in vain as they are not of type entity. With following code addition in org.hibernate.engine.Cascade.java I was able do avoid most reflection method calls without affecting the behaviour: org.hibernate.engine.Cascade.java ... public void cascade(final EntityPersister persister, final Object parent, final Object anything) throws HibernateException { ... else if ( action.requiresNoCascadeChecking() ) { // Line:162 // begin Improvement if (action == CascadingAction.PERSIST_ON_FLUSH) { Type type = persister.getPropertyTypes()[i]; if ( !type.isEntityType() ) { // Remark: goes only well as long PERSIST_ON_FLUSH noCascade implementation checks only entities continue; } } // end Improvement action.noCascade( eventSource, persister.getPropertyValue( parent, i, entityMode ), parent, persister, i ); ... best regards Guenther D. -- 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
