[Hibernate-JIRA] Created: (HHH-4055) make UpdateTimestampsCache pluggable, like QueryCache

by A. R. (JIRA)

make UpdateTimestampsCache pluggable, like QueryCache ----------------------------------------------------- Key: HHH-4055 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4055 Project: Hibernate Core Issue Type: Improvement Components: caching (L2) Affects Versions: 3.3.2 Environment: all Reporter: A. R. According to https://www.hibernate.org/213.html, one can plug-in one's own query cache using hibernate.cache.query_cache_factory, e.g. to chose a cache strategy that is not based on updateTimestamps. However, Hibernate's SessionFactoryImpl will always create an UpdateTimestampsCache if the Query Cache is enabled, even for custom Query Caches. This UpdateTimestampsCache then is always used in org.hibernate.engine.ActionQueue.execute() and afterTransactionCompletion(). Since the UpdateTimestampsCache is synchronized, this can cause bottlenecks when many threads change things (see http://tech.puredanger.com/2009/07/10/hibernate-query-cache/).. Please make the UpdateTimestampsCache also pluggable, so that one can truly and completely plug one's own Query Cache without using a Update-Timestamps or with a custom UpdateTimestampCache. -- 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-2305) refresh throws exception when database has been altered with a delete

by Markus Heiden (JIRA)

refresh throws exception when database has been altered with a delete --------------------------------------------------------------------- Key: HHH-2305 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2305 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1 Environment: Hibernate 3.2.1, Oracle 9.2 Reporter: Markus Heiden Attachments: hibernate.zip First I save an entity with a collection of cascading entities in it and flush. Then I delete these cascaded entities with a sql query. When I now do a refresh on the entity an exception is thrown, because the cascaded entities couldn't be found in the database. I expected these entities to be deleted from the (in memory) collection of the entity instead. Test case is attached. Stacktrace of test case: Hibernate: select c0_.id as id2_0_, c0_.c as c2_0_ from C c0_ where c0_.id=? org.hibernate.UnresolvableObjectException: No row with the given identifier exists: [hibernate.refresh.C#30003] at org.hibernate.UnresolvableObjectException.throwIfNull(UnresolvableObjectException.java:42) at org.hibernate.event.def.DefaultRefreshEventListener.onRefresh(DefaultRefreshEventListener.java:126) at org.hibernate.impl.SessionImpl.fireRefresh(SessionImpl.java:911) at org.hibernate.impl.SessionImpl.refresh(SessionImpl.java:894) at org.hibernate.engine.CascadingAction$4.cascade(CascadingAction.java:169) at org.hibernate.engine.Cascade.cascadeToOne(Cascade.java:268) at org.hibernate.engine.Cascade.cascadeAssociation(Cascade.java:216) at org.hibernate.engine.Cascade.cascadeProperty(Cascade.java:169) at org.hibernate.engine.Cascade.cascadeCollectionElements(Cascade.java:296) at org.hibernate.engine.Cascade.cascadeCollection(Cascade.java:242) at org.hibernate.engine.Cascade.cascadeAssociation(Cascade.java:219) at org.hibernate.engine.Cascade.cascadeProperty(Cascade.java:169) at org.hibernate.engine.Cascade.cascade(Cascade.java:130) at org.hibernate.event.def.DefaultRefreshEventListener.onRefresh(DefaultRefreshEventListener.java:99) at org.hibernate.impl.SessionImpl.fireRefresh(SessionImpl.java:911) at org.hibernate.impl.SessionImpl.refresh(SessionImpl.java:894) at org.hibernate.engine.CascadingAction$4.cascade(CascadingAction.java:169) at org.hibernate.engine.Cascade.cascadeToOne(Cascade.java:268) at org.hibernate.engine.Cascade.cascadeAssociation(Cascade.java:216) at org.hibernate.engine.Cascade.cascadeProperty(Cascade.java:169) at org.hibernate.engine.Cascade.cascadeCollectionElements(Cascade.java:296) at org.hibernate.engine.Cascade.cascadeCollection(Cascade.java:242) at org.hibernate.engine.Cascade.cascadeAssociation(Cascade.java:219) at org.hibernate.engine.Cascade.cascadeProperty(Cascade.java:169) at org.hibernate.engine.Cascade.cascade(Cascade.java:130) at org.hibernate.event.def.DefaultRefreshEventListener.onRefresh(DefaultRefreshEventListener.java:99) at org.hibernate.event.def.DefaultRefreshEventListener.onRefresh(DefaultRefreshEventListener.java:39) at org.hibernate.impl.SessionImpl.fireRefresh(SessionImpl.java:902) at org.hibernate.impl.SessionImpl.refresh(SessionImpl.java:886) at hibernate.refresh.Test.main(Test.java:46) -- 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-3360) Custom Oracle Batcher to allow batch updates for versioned data

by Manuel Dominguez Sarmiento (JIRA)

Custom Oracle Batcher to allow batch updates for versioned data --------------------------------------------------------------- Key: HHH-3360 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3360 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.3.0.CR1, 3.2.6, 3.2.5, 3.2.4.sp1, 3.2.4, 3.2.3, 3.2.2, 3.2.1, 3.2.0.ga Environment: Oracle 10g R1, 10g R2, 11g R1 (have not tried previous Oracle versions), 11g R1 drivers (older drivers should also work) Reporter: Manuel Dominguez Sarmiento Priority: Minor Attachments: C3P0OracleBatchingBatcher.java, C3P0OracleBatchingBatcherFactory.java, OracleBatchingBatcher.java, OracleBatchingBatcherFactory.java We have developed a custom Oracle Batcher which allows batching versioned data. The Oracle JDBC driver does not return update counts when using the standard JDBC 2.0 batching mechanism, however the proprietary Oracle batching mechanism allows obtaining the total batch row update count. The update counts are absolutely necessary to detect stale updates. Although it is not exactly the same, the total row update count is actually enough information to be able to batch versioned data and still detect stale updates. We'd like to contribute the attached files. They have a compile time dependency on Oracle JDBC. If this is not acceptable, it could be easily solved by using reflection. Another Batcher is provided for when the Oracle connection is being managed through c3p0 (a common deployment scenario). This has a compile time dependency on c3p0. A few "dirty" tricks were necessary to pull this off without patching other classes. Specifically, it was necessary to override Java private semantics to obtain BasicExpectation.expectedRowCount. This could be easily solved by adding an accessor method to the Expectation interface. There is one issue which we are not completely sure of, however so far we have not found any problems. When the Expectation is NONE, there is no way to check whether the total row count is correct or not, even if other batched updates do have expectations with expected row counts. Our understanding is that actually, since batching requires all statements to be of the same type (since the same PreparedStatement / CallableStatement is being used), then either ALL expectations will be NONE, or all will have an expected row count. We'd welcome comments from the Hibernate team. This could also be probably handled better by improving the Expectation interface. Oracle JDBC docs that explain the Oracle batching model: http://download.oracle.com/docs/cd/B28359_01/java.111/b31224/oraperf.htm#... As expected, implementing this solution has resulted in drastical improvement in batch processing. -- 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-644) @ManyToMany appears to ALWAYS generate a left outer join SQL

by Barry Davies (JIRA)

@ManyToMany appears to ALWAYS generate a left outer join SQL ------------------------------------------------------------ Key: ANN-644 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-644 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.0.ga Reporter: Barry Davies Priority: Minor Attachments: files.zip A collection mapping created using the @ManyToMany JPA annotation appears to create a left outer join SQL regardless of whether the joinColumn or inverseJoinColumn are marked nullable or not. This might be in error. Emmanuel asked for a JIRA issue to be created, so here we are. I have attached some files that can recreate what I believe to be the issue.

[Hibernate-JIRA] Created: (HHH-3160) Support one-to-many list associations with constraints on both (owner_id, position) and (child_id)

by Gail Badner (JIRA)

Support one-to-many list associations with constraints on both (owner_id, position) and (child_id) -------------------------------------------------------------------------------------------------- Key: HHH-3160 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3160 Project: Hibernate3 Issue Type: Sub-task Reporter: Gail Badner Assignee: Gail Badner The logic used for removing entities from one-to-many list associations can cause ConstraintViolationException will be thrown if there are constraints on both (owner_id, position) and (child_id) in the "collection table". If the association is on a join table, the "collection table" is the join table; otherwise, the "collection table" is the child entity table.. Currently, SchemaExport does not put a constraint on (owner_id, position) when exporting one-to-many list associations on a foreign key. SchemaExport should be updated to also export this constraint. See HHH-1268 for a description of how to reproduce this issue. For one-to-many list associations on a foreign key, the workaround is to either define the constraint on (owner_id, position) in the child entity table as deferred. If this is not on option for a particular Dialect, the constraint on (owner_id, position) will have to be excluded. For a one-to-many list association on a join table, the workaround is to either define the constraint on (child_id) in the join table as deferred. If this is not on option for a particular Dialect, the constraint on (child_id) will have to be excluded. -- 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

org.hibernate.util.IdentitySet.iterator() return Map.Entry instances instead of actual elements ----------------------------------------------------------------------------------------------- Key: HHH-5146 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5146 Project: Hibernate Core Issue Type: Bug Components: core Reporter: Nicklas Nordborg Priority: Trivial Attachments: patch.txt By accident I used the IdentitySet implementation in my code and got ClassCastException:s when iterating over it. It turns out that the iterator() method returns Map.entrySet().iterator() instead of Map.keySet().iterator(). There is also a similar problem with the toArray() methods.

by Geoffrey De Smet (JIRA)

Regular expressions (regex) boolean operator in HQL's where clause: rlike in mysql, regexp_match in informix, ... (regression from hibernate2) ---------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-3404 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3404 Project: Hibernate3 Issue Type: New Feature Components: query-hql Affects Versions: 3.2.6 Reporter: Geoffrey De Smet Hibernate 2 supported the rlike boolean operator (at least for mysql): HB-1034. Hibernate3 currently doesn't. It turns out that most mainstream databases support regular expression patterns (independently from normal like patterns).

[Hibernate-JIRA] Created: (HHH-3887) Envers hbm xml based configuration

by Helmut Pasch (JIRA)

Envers hbm xml based configuration ---------------------------------- Key: HHH-3887 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3887 Project: Hibernate Core Issue Type: Improvement Components: envers Affects Versions: 3.5 Environment: Hibernate: All Hibernate Versions including Envers as subproject Our Project: Hibernate 3.3.1, Spring 2.5.6, Spring DM 1.2.0, Swing, GWT, .... Reporter: Helmut Pasch Currently the tool library Envers can only be configured / mapped to java POJOs by annotations. We would appreciate if this mapping could be done by hbm xml files. Using this approach the POJO won't be bound to Envers annotations. They simply would be left as POJOs instead of transformed to JPA like Entity Beans. We use POJOs to directly serialize them to a client tier, e.g. a Swing or GWT client tier. If our POJOs have to rely on Envers annotations similar like JPA annotations we see only two options objects may leave the server tier. First by a copy to an annotation less value object, which is consuming performance and resources. Second by coping / using Envers / Hibernate libraries for reference purposes on the client tier. Both solutions are not very attractive compared to the very well working hbm xml approach Hibernate core ORM functionality provides us. It is our intention to reduce / eliminate in client server communication model transformations like coping objects or transforming them to other formats like XML, e.g. like web services does. The easiest way would be to just serialize the Java POJO objects. But never then less the client should only depend (logically) on the server API. It is not intended to rely on a specific server implementation. -- 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
