[Hibernate-JIRA] Created: (HHH-2413) Offer a way to log bound jdbc parameters in a uniform way for UserType implementors

by Baptiste MATHUS (JIRA)

Offer a way to log bound jdbc parameters in a uniform way for UserType implementors ----------------------------------------------------------------------------------- Key: HHH-2413 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2413 Project: Hibernate3 Type: Improvement Versions: 3.2.2 Reporter: Baptiste MATHUS Priority: Minor At the moment, when someone implements a UserType, the bound parameters won't be displayed in not explicitly displayed via loggers. For example, here is what the code of NullableType.nullSafeGet() is : public final void nullSafeSet(PreparedStatement st, Object value, int index) throws HibernateException, SQLException { try { if ( value == null ) { if ( IS_TRACE_ENABLED ) { log().trace( "binding null to parameter: " + index ); } st.setNull( index, sqlType() ); } else { if ( IS_TRACE_ENABLED ) { log().trace( "binding '" + toString( value ) + "' to parameter: " + index ); } set( st, value, index ); } } catch ( RuntimeException re ) { log().info( "could not bind value '" + toString( value ) + "' to parameter: " + index + "; " + re.getMessage() ); throw re; } catch ( SQLException se ) { log().info( "could not bind value '" + toString( value ) + "' to parameter: " + index + "; " + se.getMessage() ); throw se; } } IMO, it would be quite a good thing to provide some method in Hibernate, something like logBoundParameter() that would do the log like above : > log().trace( "binding '" + toString( value ) + "' to parameter: " + index ); This method could then be just called by implementors so as to guaranty the display is always the same about bound parameters. Even more, I think it should use a special logger, just like the org.hibernate.SQL one to display this parameters. In fact, at the moment, I feel the reference documentation is not very clear about this : see http://www.hibernate.org/hib_docs/v3/reference/en/html/session-configurat.... It says : > org.hibernate.type Log all JDBC parameters But that's not completely true: it will only log bound parameters that are parameters typed with standard types coming from the org.hibernate.type package. Any custom UserType won't display anything until you: 1) put the right log4j line for the package where your userType is located ; 2) think about explicitly logging those parameter values in your custom UserType (cf. my first point). I'm not sure I made myself totally clear,. If so, please let me know. If you think that would be worth an improvement, I'll give a look to provide a patch for this. Thanks a lot. -- 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-2845) "Another ORA-00907: missing right parenthesis" bug with Oracle

by Dean Pullen (JIRA)

"Another ORA-00907: missing right parenthesis" bug with Oracle -------------------------------------------------------------- Key: HHH-2845 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2845 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: hibernate-entitymanager.jar (3.3.1ga) hibernate-annotations.jar (v 3.3.0ga) hibernate-commons-annotations.jar (within Hibernate Annotations.rar\lib) ejb3-persistence.jar (within Hibernate Annotations.rar\lib) hibernate3.jar (v 3.2.5.ga) Oracle 10g Reporter: Dean Pullen I'm using JBoss 4.2.1GA, with the Hibernate environment described above, using Oracle 10g, and attempting to perform a query. I've been receiving a "ORA-00907: missing right parenthesis" error when attempting to perform the query. Now a similar bug had this down to Hibernate using the 'as' keyword in the query, aliasing the table name - something that has been fixed in Hibernate 3.3.0ga. (Aliasing a table in the SQL spec is optional, Oracle doesn't support it) But I still get the same error. The query still contains the 'as' keyword (but not aliasing a table) Here is an example: I have two tables. CSIUsers and CSIUserSurveys. There is a one-to-many mapping between CSIUsers to CSIUserSurveys. Query query = entityManager.createQuery("FROM " + CSIUser.class.getSimpleName() + " cu LEFT JOIN cu.csiUserSurveys us" + " WHERE NOT EXISTS (SELECT us FROM cu.csiUserSurveys us WHERE us.csiUserId = cu.csiUserId)"); Result: [[14 Sep 2007 15:43:52] DEBUG org.hibernate.util.JDBCExceptionReporter - could n ot execute query [select csiuser0_.CSI_USER_ID as CSI1_15_0_, csiusersur1_.CSI_U SER_ID as CSI1_16_1_, csiusersur1_.SURVEY_TYPE_CODE as SURVEY2_16_1_, csiuser0_.

[Hibernate-JIRA] Created: (EJB-402) Ejb3ConfigurationObjectFactory needs to use MarshalledValueInputStream

by Galder Zamarreno (JIRA)

Ejb3ConfigurationObjectFactory needs to use MarshalledValueInputStream ---------------------------------------------------------------------- Key: EJB-402 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-402 Project: Hibernate Entity Manager Issue Type: Bug Affects Versions: 3.4.0.CR2, 3.3.2.GA, 3.2.1 Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 3.4.0.GA Ejb3ConfigurationObjectFactory should use MarshalledValueInputStream instead of ObjectInputStream, otherwise looking up configuration from isolated deployments won't work correcly and you'll get ClassNotFoundExceptions. MarshalledValueInputStream is different from ObjectInputStream in that it uses the thread context classloader to load classes rather than the system classloader. -- 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-2935) Cascading save on OneToMany causes not null constraint violation on child table

by Aaron Luchko (JIRA)

Cascading save on OneToMany causes not null constraint violation on child table ------------------------------------------------------------------------------- Key: HHH-2935 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2935 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.1 Environment: hibernate-3.2.1, hibernate-annotations-3.2.1 Reporter: Aaron Luchko Attachments: saveNull.zip When defining a OneToMany relationship, controlled by the parent, and not nullable by the child, there's an issue when trying to insert the initially created columns. With a schema attached as thus public class Parent { ... @OneToMany(targetEntity = Child.class, cascade = { CascadeType.ALL }) @Cascade( { org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.DELETE_ORPHAN }) @JoinColumn(name = "parent_child") public List<Child> getChildren() { return children; } } public class Child{ ... @ManyToOne @JoinColumn(name = "parent_child", insertable = false, updatable = false, nullable=false) public Parent getParent() { return parent; } } And running a section of code such as this Session session = HibernateUtil.getSession(); session.beginTransaction(); Parent parent = new Parent(); int times = 2; List<Child> children = new ArrayList<Child>(times); for (int i = 0; i < times; i++) { Child child = new Child(); children.add(child); child.setParent(parent); } parent.setChildren(children); session.save(parent); session.getTransaction().commit(); Hibernate attempts to run the following series of queries select child_.id from Child child_ where child_.id=? select child_.id from Child child_ where child_.id=? insert into Parent (id) values (?) insert into Child (id) values (?) insert into Child (id) values (?) update Child set parent_child=? where id=? update Child set parent_child=? where id=? The problem is that in initial batch inserting the two children fails violating the not null constraint before the update can assign a value to parent_child. I've reproduced this with postgresql and mysql (after setting the dialect to org.hibernate.dialect.MySQLInnoDBDialect, MyISAM doesn't catch the constraint violation). As a workaround one can simply leave off the nullable=false. I've attached a full testcase. thanks, Aaron -- 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-2272) Serious performance problems when saving large amount of transient entities with collections of transient entities

by Markus Heiden (JIRA)

Serious performance problems when saving large amount of transient entities with collections of transient entities ------------------------------------------------------------------------------------------------------------------ Key: HHH-2272 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2272 Project: Hibernate3 Type: Task Components: core Versions: 3.2.0.ga Environment: Hibernate 3.2.0 on Oracle 9.2 Reporter: Markus Heiden When saving many (e.g. 50000) transient entities with a collection of transient entities, for each collection element the whole persistence context is searched (by StatefulPersistenceContext#getIndexInOwner() and StatefulPersistenceContext#getOwnerId) and its even searched twice when the collection is an indexed collection. This leads to an enormous amount (> 1000000) of iterations over all entities and over all collection elements of each entity. Especially when one saves only the same type of entities this leads to times of hours(!) even on a fast machine before any insert statement is even issued. This issue is related to HHH-1612, but fixing issue HHH-1612 won't resolve this problem (I have explored this with a hack which fixes HHH-1612). In my eyes there are two ways to solve this problem: 1) When cascading the save of a parent, the parent cascade can fill the persistence context with information about its collection elements. E.g. before cascading the save to a collection a parent can add a (child, parent) pair to a map in the persistence context to avoid the above described iterations. Then a simple Map#get() would be sufficient in most cases to get the parent. 2) When cascading, the parent has to be passed with the cascaded (e.g. saved) element. But this is no good solution, because it affects some well known hibernate apis. -- 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-3271) Prepare Statement Caching

by lalit railwani (JIRA)

Prepare Statement Caching ------------------------- Key: HHH-3271 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3271 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Hibernate 3.2.5, Oracle 10g Reporter: lalit railwani We are using Hibernate 3.2.5 are trying to evaluate hibernate batching vis a vis JDBC batching. As per our results the hibernate batching takes approx 2 times the time taken by JDBC batching. The problem is we need to commit the batches also so in a loop we are commiting the transaction also (batching). But for every new loop hibernate creates new prepared statements i.e. if we have 20 batches 20 prepared statements per table/entity are being created but in case of JDBC the same can be done using 1 prepared statement per table/entity. Hibernate does reuse the prepared statements within a batch but not across batches. If hibernate can reuse these statements it would significantly reduce the timings and would bring the hibernate batching close to jdbc batching. This is happening even after enabling prepare statement caching in the hibernate cfg xml. -- 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
