[Hibernate-JIRA] Created: (HHH-4953) Inconsistent behavior when fetching cached subclass entities from 2L

by Guenther Demetz (JIRA)

Inconsistent behavior when fetching cached subclass entities from 2L -------------------------------------------------------------------- Key: HHH-4953 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4953 Project: Hibernate Core Issue Type: Bug Components: caching (L2) Affects Versions: 3.5.0-CR-2, 3.5.0-CR-1, 3.5.0-Beta-4, 3.5.0-Beta-3, 3.5.0-Beta-2, 3.5.0.Beta-1, 3.3.1, 3.2.5 Environment: Hibernate3.5.0CR2,HSQLDB, EHCache as 2L-cache Impl Reporter: Guenther Demetz Attachments: Test2LCache.jar Enabling the hibernate second-level cache is leading to inconsistent behavior when fetching cached subclass entities as opposed to fetching non-cached subclass entities. For more informations, please see https://forum.hibernate.org/viewtopic.php?f=1&t=1002880&p=2425931#p2425931 Testcase attached. Cause: IMHO the bug consists in the fact, that persister.getRootEntityName() instead to persister.getEntityName() is passed as 3thrd parameter to the constructor of CacheKey in most places where CacheKey is used, for example in DefaultLoadEventListener.java: new CacheKey( event.getEntityId(), persister.getIdentifierType(), persister.getRootEntityName(), source.getEntityMode(), source.getFactory() In this way the real entity name get swallowed and the type-saveness is not guaranteed anymore. Workaround: Subclass2 tofind = null; try { tofind = (Subclass2) em.find(Subclass2.class,"identifier1"); } catch (ClassCastException cc) { // swallow , this is a workaround } -- 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-3854) Issue with greedy loading of associations (default-lazy=false )

by Amar Singh (JIRA)

Issue with greedy loading of associations (default-lazy=false ) --------------------------------------------------------------- Key: HHH-3854 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3854 Project: Hibernate Core Issue Type: Bug Components: envers Environment: Hibernate - core 3.4.0-SNAPSHOT, Hibernate-envers (from trunk) Reporter: Amar Singh Attachments: greedy-loading.zip I have an Entity GP which has a many to one association to entity CA. <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="org.hibernate.envers.test.integration.onetoone.bidirectional" default-lazy="false"> <class name="BidirectionalRefIngPK" table="BIDIRECTIONAL_REFERENCING_ENTITY"> <id name="id" type="long" column="BIDIRECTIONAL_REFERENCING_ID" > <generator class="native"/> </id> <property name="data"/> <many-to-one name="reference" cascade="save-update" class="BidirectionalRefEdPK" column="BIDIRECTIONAL_REFERENCED_ID"/> </class> <class name="BidirectionalRefEdPK" table="BIDIRECTIONAL_REFERENCED_ENTITY"> <id name="longId" type="long" column="BIDIRECTIONAL_REFERENCED_ID"> <generator class="native"/> </id> <property name="data"/> </class> </hibernate-mapping> With this when I load a previous version of BidirectionalRefIngPK, the loading mechanism tries to create a proxy for BidirectionalRefEdPK, but in my case lazy is false so an internal call to createProxy will return NULL hence . This happens in ToOneIdMapper.java in method mapToEntityFromMap around line 82, which then internally calls for AbstractEntityTuplizer.java line 395 for getProxyFactory() ending in NULL pointer exception because proxy factory is null as mine is a greedy loading. TO REPRODUCE ~~~~~~~~~~~~~ Please find a zipped folder attached. The zipped file has 4 files: - GreedyLoading.java (actual testng test case) - BidirectionalRefEdPK.java (Entity 1) - BidirectionalRefIngPK.java (Entity 2) - greedyloading.hbm.xml Please place the three java files in its package (org.hibernate.envers.test.integration.onetoone.bidirectional), couldn't find the right package so created test case accordingly. Put the greedyloading.hbm.xml in src/test/resources. Now when testng runs GreedyLoading.java you should see NPE. -- 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

by Guido Müller (JIRA)

JPA Query with InExpression and Collection_valued_input_parameter Complains About Bad Syntax -------------------------------------------------------------------------------------------- Key: HHH-5126 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5126 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.1 Reporter: Guido Müller Priority: Blocker JPA 2.0 spec final chapter 4.6.9 In Expressions In the spec there are 3 alternatives allowed for the query argument. For the 3rd alternative there are no parenthesis allowed. Hibernate seems to expect these illegal parenthesis.

[Hibernate-JIRA] Created: (HHH-2891) Query cache fails on many-to-many select

by Oleg Efimov (JIRA)

Query cache fails on many-to-many select ---------------------------------------- Key: HHH-2891 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2891 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.5 Reporter: Oleg Efimov I have two entities, User and Group, with many-to-many relation: -------------------------------------------------------------------------------------------------- User.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="test.hibernate"> <class name="User" table="`USER`"> <id name="id" type="long" unsaved-value="null"> <column name="USER_ID" not-null="true"/> <generator class="native"/> </id> <property name="login"> <column name="LOGIN" not-null="true" length="255"/> </property> <bag name="groups" table="USER_GROUP" lazy="false" cascade="none"> <key column="USER_ID"/> <many-to-many class="Group" column="GROUP_ID"/> </bag> </class> </hibernate-mapping> -------------------------------------------------------------------------------------------------- Group.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="test.hibernate"> <class name="Group" table="`GROUP`"> <id name="id" type="long" unsaved-value="null"> <column name="GROUP_ID" not-null="true"/> <generator class="native"/> </id> <property name="name"> <column name="GROUPNAME" not-null="true" length="100"/> </property> <bag name="users" table="USER_GROUP" lazy="true" inverse="true" cascade="all-delete-orphan"> <key column="GROUP_ID"/> <many-to-many class="User" column="USER_ID"/> </bag> </class> <query name="Group.select.by.login" cacheable="true"><![CDATA[ select user.groups from User user where user.login=? ]]> </query> </hibernate-mapping> ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- test.hibernate.User and test.hibernate.Group classes are just simple beans. In Group.hbm.xml there is a query called "Group.select.by.login", it's intended to be cached. So I add corresponding properties to Hibernate configuraition: -------------------------------------------------------------------------------------------------- properties.put("hibernate.cache.provider_class", "org.hibernate.cache.EhCacheProvider"); properties.put("hibernate.cache.use_query_cache", "true"); ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Configuration has no extra parameters. Then I'm trying to execute the query two times: -------------------------------------------------------------------------------------------------- test fragment SessionFactory sessionFactory = configuration.buildSessionFactory(); Session session = null; try { session = sessionFactory.openSession(); Query query = session.getNamedQuery("Group.select.by.login"); List<Group> groups; groups = query.setParameter(0, "admin").list(); // +++++++++++++++This list() returns list of two Group objects, ok +++++++++++++++ System.out.println("-----------------------------------------------------------------------------------"); for (Group group : groups) { System.out.println(group.getName()); } System.out.println("-----------------------------------------------------------------------------------"); groups = query.setParameter(0, "admin").list(); // +++++++++++++++This list() returns list of two nulls +++++++++++++++ System.out.println("-----------------------------------------------------------------------------------"); for (Group group : groups) { System.out.println(group.getName()); } System.out.println("-----------------------------------------------------------------------------------"); } finally { if (session != null) { session.close(); } sessionFactory.close(); } ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The first query returns list of, in my case, two groups. The second query returns list of two nulls instead of the same list. I've investigated the problem, and found the following: Query return value is "user.groups", and during query analysis (org.hibernate.hql.ast.QueryTranslatorImpl:160) query return type is defined as "org.hibernate.type.BagType(test.hibernate.User.groups)". This seems to be the problem, as during query put operation org.hibernate.CollectionType.disassemble is called (org.hibernate.cache.StandardQueryCache:80), which simply returns null as owner is null. If this query is not a misuse, then I think, something is to be done at the time of analysis, so that return type be somewhat different.

by Mattias Jiderhamn (JIRA)

LEFT OUTER JOIN subcriteria filters children -------------------------------------------- Key: HHH-2049 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2049 Project: Hibernate3 Type: Bug Components: query-criteria Versions: 3.1.3, 3.2.0.cr4 Environment: Hibernate 3.1.3/3.2.0rc4, hsqldb 1.8 Reporter: Mattias Jiderhamn Attachments: SubCriteriaTestCase.zip When using the Criteria API with LEFT OUTER JOIN to add criterias to the children, i.e. criteria.createCriteria("children", JoinFragment.LEFT_OUTER_JOIN) the child collections will only contain those children matching the criteria.
