[Hibernate-JIRA] Created: (HHH-5580) tracking entity names in a revision

by Vardan Akopian (JIRA)

tracking entity names in a revision ----------------------------------- Key: HHH-5580 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5580 Project: Hibernate Core Issue Type: New Feature Components: envers Affects Versions: 3.5.5 Environment: hibernate 3.5.5 Reporter: Vardan Akopian Attachments: envers-entity-names.patch Currently Envers provides no way of finding which entities have been affected in a given revision. I.e. given a revision number it's impossible to find all the versions of all the entities for that revision. For example, all the search methods in the AuditQuery API take the entity class as a parameter. In our application we need to be able to retrieve all the changes for a given revision number without prior knowledge of which entities have been modified. Similar questions and requests have been posted in the envers forums before. The attached patch has a simple implementation for this feature. It adds 2 simple methods to the RevisionListener interface, that are called from AuditProcess and allow the Revision Entity to keep track of the entity names that are changed. The test cases show the simple usage for this. -- 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-3051) NPE while query.list on a Native SQL, using L2 cache

by Amit Kapoor (JIRA)

NPE while query.list on a Native SQL, using L2 cache ---------------------------------------------------- Key: HHH-3051 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3051 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Hibernate 3.2.5ga Database Oracle 9i Jdk - 1.4.2_13 EHCache 1.2.3 / OsCache 2.1 both Reporter: Amit Kapoor I get an NPE when i try to execute a native query. Below is the excerpt of the code that throws NPE: String sqlQuery = "select emp_id, emp_first_name from employee_mt"; SQLQuery query = session.createSQLQuery(sqlQuery); query.setCacheable(true).setCacheRegion("TEST_REGION"); query.addScalar("emp_id"); query.addScalar("emp_first_name"); List list = query.list(); query.list() throws the following NPE: java.lang.NullPointerException at org.hibernate.type.TypeFactory.disassemble(TypeFactory.java:451) at org.hibernate.cache.StandardQueryCache.put(StandardQueryCache.java:83) at org.hibernate.loader.Loader.putResultInQueryCache(Loader.java:2194) at org.hibernate.loader.Loader.listUsingQueryCache(Loader.java:2138) at org.hibernate.loader.Loader.list(Loader.java:2096) at org.hibernate.loader.custom.CustomLoader.list(CustomLoader.java:289) at org.hibernate.impl.SessionImpl.listCustomQuery(SessionImpl.java:1695) at org.hibernate.impl.AbstractSessionImpl.list(AbstractSessionImpl.java:142) at org.hibernate.impl.SQLQueryImpl.list(SQLQueryImpl.java:152) at poc.hibernate.caching.QueryCaching.fireNativeSql(QueryCaching.java:112) at poc.hibernate.caching.QueryCaching.fireQuery(QueryCaching.java:38) at poc.hibernate.caching.QueryCaching.main(QueryCaching.java:27) I tried tracing through the Hibernate code code and saw that the types[] in the at the time of execution of types[i].disassemble( row[i], session, owner ) (TypeFactory.disassemble()) was holding both the types as null. However before reaching that piece of code CustomLoader.autoDiscoverTypes(resultset) had already resolved the resultTypes to appropriate values. Hope this helps. -- 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: (HSEARCH-539) Add Indexing Support(out of the box) For Simple Collections, Like Set<Integer>

by Zach Kurey (JIRA)

Add Indexing Support(out of the box) For Simple Collections, Like Set<Integer> ------------------------------------------------------------------------------ Key: HSEARCH-539 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-539 Project: Hibernate Search Issue Type: New Feature Components: mapping Affects Versions: 3.2.0.Final Environment: N/A Reporter: Zach Kurey >From both the documentation and the Hibernate Search In Action book it was unclear to me that simple collections were not able to be indexed out of the box by just adding a @IndexEmbedded or @Field annotation, and instead require a custom field bridge. When I say simple collection I mean Sets/Lists/Collections of Integer/Double/String/Float/etc. It would seem, given the already advanced indexing support in Hibernate Search, that this really should be a basic out of the box feature as I'm sure most of the folks using Search have had to implement such a bridge at some point. Note that I could still be missing an non-obvious feature or there may be a good reason for not providing it via @IndexEmbedded or @Field automatically. To be completely clear I have: @CollectionOfElements @JoinTable(name="enrollment_groups", joinColumns={@JoinColumn(name="enrollee_id")}) @Column(name="enrollment_group_id") @IndexedEmbedded private Set<String> utilityEnrollmentGroups; If I were to change this to a group of embedded types, everything gets indexed just fine.

[Hibernate-JIRA] Created: (HHH-4580) Possible Sybase bug causes AssertionFailure in QueryByExampleTest

by Strong Liu (JIRA)

Possible Sybase bug causes AssertionFailure in QueryByExampleTest ----------------------------------------------------------------- Key: HHH-4580 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4580 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.0-Beta-2, 3.5.0.Beta-1, 3.3.2, 3.2.4.sp1 Environment: sybase 15 Reporter: Strong Liu Test QueryByExampleTest.testJunctionNotExpressionQBE fails due to a possible bug in Sybase 15. The same test passes for Sybase 12.5. The test expects two records as a result for a query, but it gets 3. After some debugging with the query that Hibernate generated, I end up with these two simpler ones: select id from Componentizable where not (name like ? and subName1 like ?) select id from Componentizable where not (name like 'hibernate' and subName1 like 'ope%') The first one returns three records, while the second returns two. The interesting part is that if I replace the first parameter in the first query by a hardcoded value ("hibernate"), it still returns 3 records. That means that the problem is probably with the binding of JDBC parameters containing a wildcard % . -- 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-814) OneToOne Unidirectional Support

by Rachit (JIRA)

OneToOne Unidirectional Support ------------------------------- Key: ANN-814 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-814 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.4.0.GA Environment: Oracle 10g, Java 1.5 Reporter: Rachit Priority: Blocker I tried hard for unidirectional OneToOne mapping as below: @Entity @Table(name = "PARTY") public class Party{ private Person person; private String key; @OneToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL,) @PrimaryKeyJoinColumn(name = "PARTY_ID", referencedColumnName = "PERSON_PARTY_ID") public Person getPerson() { return person; } public void setPerson(Person person) { this.person = person; } @Id @GeneratedValue(generator = "system-uuid") @GenericGenerator(name = "system-uuid", strategy = "uuid") @Column(name = "PARTY_ID", nullable = false) public String getKey() { return key; } private void setKey(String key) { this.key = key; } } and it is one-to-one mapped to Person as: @Entity(name = "Person") @Table(name = "PERSON") public class Person { private String key; @Id @Column(name = "PERSON_PARTY_ID") public String getKey() { return key; } public void setKey(String key) { this.key = key; } } Now in Person, I deliberately dont have sysUUID as generated as then it generates a unique value for person and the association gets lost. With this mapping hibernate throws the following exception : Caused by: org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): Person. I read and saw constrained="true" being used in mapping files, which I couldnt use as there is no attribute like it in OneToOne annotation.

[Hibernate-JIRA] Created: (HHH-4727) Add option to specify foreign key name on table with shared primary key used in one-to-one relationship

by Pavla Nováková (JIRA)

Add option to specify foreign key name on table with shared primary key used in one-to-one relationship --------------------------------------------------------------------------------------------------------- Key: HHH-4727 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4727 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.3.2 Reporter: Pavla Nováková There is currently no way to specify (user friendly) foreign key name on table with shared primary key used in One-to-One mapping. The most intuitive way would be to accept @ForeignKey on property level (see the comment in the code below) or on entity level (similar way to usage in joined inheritance) or last option may be add parameter in foreign generator. {code} @Entity public class ExampleEntity implements Serializable { @Id @GenericGenerator(name = "foreign-generator", strategy = "foreign", parameters=@Parameter(name="property", value="parentExampleEntity")) @GeneratedValue(generator = "foreign-generator") private Long id; ... @PrimaryKeyJoinColumn @OneToOne(fetch=FetchType.LAZY, optional=false) @org.hibernate.annotations.ForeignKey(name="parent_entity_fk") // this is currently ignored private ParentExampleEntity parentExampleEntity; ... } {code} -- 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
