[Hibernate-JIRA] Created: (HSEARCH-188) Add an option to use JMS in a JTA tx (rather than the post TX work done right now)

[Hibernate-JIRA] Created: (HHH-3958) Superfluous generated updates cause Violation of UNIQUE KEY constraint

by Guenther Demetz (JIRA)

Superfluous generated updates cause Violation of UNIQUE KEY constraint ---------------------------------------------------------------------- Key: HHH-3958 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3958 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: 3.3.1 GA, SQLServer 2008 Reporter: Guenther Demetz Priority: Minor Attachments: Testcase.jar When deleting a entire closure of objects associated over @ManyToOne within one single transaction, then on commit the FlushEventListener creates update statements on objects which are going to be deleted anyway. These update statements seems not only be useless, in certain scenarios they lead to Constraint Violation Exceptions, see the example here: @Entity public class A { public A() { } @Id @GeneratedValue private long oid; } @Entity @Table(uniqueConstraints = {@UniqueConstraint(columnNames={"assA_oid"})}) public class B { public B() {}; @Id @GeneratedValue private long oid; @javax.persistence.ManyToOne protected A assA = null; } A a1 = new A(); em.persist(a1); A a2 = new A(); em.persist(a2); B b1 = new B(); b1.assA = a1; // set unique association B b2 = new B(); b2.assA = a2; // set unique association em.persist(b1); em.persist(b2); em.getTransaction().commit(); em.getTransaction().begin(); em.remove(a1); em.remove(a2); em.remove(b1); em.remove(b2); em.getTransaction().commit(); // p6spy report: // update B set assA_oid='',version=0 where oid=1 and version=0 // update B set assA_oid='',version=0 where oid=2 and version=0 --> this raises "Violation of UNIQUE KEY constraint on all DB's which don't allow multiple null values in a unique index See testcase in attachment -- 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-4030) Implement support for native recursive query functionality of popular DBMSes

by David Cracauer (JIRA)

Implement support for native recursive query functionality of popular DBMSes ---------------------------------------------------------------------------- Key: HHH-4030 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4030 Project: Hibernate Core Issue Type: New Feature Components: core, query-hql, query-sql Environment: Hibernate 3.3.2, MSSQL Reporter: David Cracauer We have a couple of areas in our system where need to load tree structures from our database. These trees can be very deep (often 20+ levels). SQL Server 2005 introduced Common Table Expressions, a kind of in-line view that can be used recursively. These allow us to quickly get a result set like this: id, label, parentId 1, foo, null 2, foo2, 1 3, foo3, 2 4, foo4, 2 5, foo5, 4 6, foo6, 1 >From a tree like this: [1, foo] | | -[2, foo2] | | - [3, foo3] | | - [4, foo4] | | - [5, foo5] |- [6, foo6] using a query like this (not tested): with MyCTE( id, label, parentId) as ( select n.id, n.label, n.parentid from Node n UNION ALL select c.id, c.label, c.parentId from MyCTE c inner join Node n on n.id=c.parentId) select * from MyCTE It happens many times more quickly than we've been able to load the graphs with Hibernate, even using batching etc. We've tried using hibernate's built in native sql support without success. The alias injection breaks the Common Table Expression definition ( with MyCTE ), as it is a view definition and doesn't allow for the 'id as id_276' syntax, rather requiring just a column name. I know that there are several other major DBMSes that support recursive querying now. Is there a way to have support for this functionality in hibernate core? -- 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-3961) SQLServerDialect, support nowait in LockMode.UPGRADE_NOWAIT

by Guenther Demetz (JIRA)

SQLServerDialect, support nowait in LockMode.UPGRADE_NOWAIT ------------------------------------------------------------ Key: HHH-3961 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3961 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.3.1 Environment: 3.3.1 GA , SQLServer2008 Reporter: Guenther Demetz Priority: Trivial The method SQLServerDialect#appendLockHint currently ignores the LockMode.UPGRADE_NOWAIT returning the same string as for LockMode.UPGRADE. public String appendLockHint(LockMode mode, String tableName) { if ( mode.greaterThan( LockMode.READ ) ) { // does this need holdlock also? : return tableName + " with (updlock, rowlock, holdlock)"; return tableName + " with (updlock, rowlock)"; } else { return tableName; } } As SQLServer supports the nowait option I propose the following improvement: public String appendLockHint(LockMode mode, String tableName) { if ( mode == LockMode.UPGRADE_NOWAIT) { return tableName + " with (updlock, rowlock, nowait)"; } else if ( mode.greaterThan( LockMode.READ ) ) { // does this need holdlock also? : return tableName + " with (updlock, rowlock, holdlock)"; return tableName + " with (updlock, rowlock)"; } else { return tableName; } } A test gave me a correct behaviour: if the concerning row is already locked, then after Lock request time out period exceeded following exception is thrown: org.hibernate.exception.SQLGrammarException: could not lock: [persistent.jpa.AssociationsClassPeer#1] at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:90) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.dialect.lock.SelectLockingStrategy.lock(SelectLockingStrategy.java:115) at org.hibernate.persister.entity.AbstractEntityPersister.lock(AbstractEntityPersister.java:1361) at org.hibernate.event.def.AbstractLockUpgradeEventListener.upgradeLock(AbstractLockUpgradeEventListener.java:108) at org.hibernate.event.def.DefaultLockEventListener.onLock(DefaultLockEventListener.java:87) at org.hibernate.impl.SessionImpl.fireLock(SessionImpl.java:611) at org.hibernate.impl.SessionImpl.lock(SessionImpl.java:603) ...

[Hibernate-JIRA] Created: (HHH-3718) call to id getter initializes proxy when using AccessType( "field" )

by Paul Lorenz (JIRA)

call to id getter initializes proxy when using AccessType( "field" ) -------------------------------------------------------------------- Key: HHH-3718 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3718 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: hibernate 3.3.1, hibernate annotations 3.4.0, running on windows, linux and solaris, using sybase 15 Reporter: Paul Lorenz Calling getter for id when using AccessType( "field" ) causes proxy initialization. In org.hibernate.proxy.proxy.pojo.BasicLazyInitializer there is the code else if ( isUninitialized() && method.equals(getIdentifierMethod) ) { return getIdentifier(); } However, when using field access, the getIdentifierMethod will be null. I fixed this for us by changing DirectPropertyAccessor by adding a Method attribute to the DirectGetter inner class, and looking up the appropriate getter in the constructor. As far as I can tell, getMethod is only used in two places. In the above case, to the get the identity getter and in PojoComponentTupilizer.isMethodOf. This doesn't seem to break anything. I don't know if this is a clean solution, seems a little hacky to me, however, it would be great if the issue could be fixed somehow. public static final class DirectGetter implements Getter { private final transient Field field; private final Class clazz; private final String name; private Method method; DirectGetter(Field field, Class clazz, String name) { this.field = field; this.clazz = clazz; this.name = name; try { BeanInfo beanInfo = Introspector.getBeanInfo( clazz ); PropertyDescriptor[] pdArray = beanInfo.getPropertyDescriptors(); if ( pdArray != null ) { for (PropertyDescriptor pd : pdArray ) { if ( pd.getName().equals( name ) ) { this.method = pd.getReadMethod(); } } } } catch ( Exception e ) { // ignore } } public Object get(Object target) throws HibernateException { try { return field.get(target); } catch (Exception e) { throw new PropertyAccessException(e, "could not get a field value by reflection", false, clazz, name); } } public Object getForInsert(Object target, Map mergeMap, SessionImplementor session) { return get( target ); } public Method getMethod() { return method; } public String getMethodName() { return method == null ? null : method.getName(); } public Class getReturnType() { return field.getType(); } Object readResolve() { return new DirectGetter( getField(clazz, name), clazz, name ); } public String toString() { return "DirectGetter(" + clazz.getName() + '.' + name + ')'; } } -- 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
