[Hibernate-JIRA] Created: (HHH-6876) Hibernate doesn't support empty collection as parameter of javax.persistence.criteria.Expression "in" method parameter

Hibernate doesn't support empty collection as parameter of javax.persistence.criteria.Expression "in" method parameter ---------------------------------------------------------------------------------------------------------------------- Key: HHH-6876 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6876 Project: Hibernate Core Issue Type: Bug Components: query-criteria, query-hql Affects Versions: 4.0.0.CR6 Environment: Using Mysql5.1 (org.hibernate.dialect.MySQL5InnoDBDialect) Reporter: Yann Le Moigne Looking at http://docs.oracle.com/javaee/6/api/javax/persistence/criteria/Expression..., there is nothing said about empty collection, so, we presume it is possible to use it. If this presumption is right, well hibernate break the spec because using empty collection as a parameter will end with something like "org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected end of subtree [select generatedAlias0 from MyEntity as generatedAlias0 where generatedAlias0.id in ()] -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-2031) Add functions to Dialect that can disable use of schema and catalog parts -- for HSQLDB support

by Brian Holmes (JIRA)

Add functions to Dialect that can disable use of schema and catalog parts -- for HSQLDB support ----------------------------------------------------------------------------------------------- Key: HHH-2031 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2031 Project: Hibernate3 Type: Patch Components: core Versions: 3.1.3 Environment: This patch is against r9668 of /tags/v313/Hibernate3. Reporter: Brian Holmes Attachments: hibernate3-v313-support_schema_catalog_names.patch HSQLDB does not support the use of three part names, that is Tables with schema and catalog parts. This patch adds two functions to Dialect: supportsSchemaNames() and supportsCatalogNames(). Table.getQualifiedName() checks these values to decide whether to use or ignore the schema and catalog parts. By default these are enabled in Dialect. This patch only disables their use in HSQLDialect. This change is necessary for people who normally use Schema and Catalog names for access their primary database, but also use HSQLDB for Unit Testing. Without it, HSQLDB is unusable for Unit Testing because it fails on use of any catalog or schema names. -- 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-4607) Deleted entities incorrectly reloaded within persistence context due to 2L cache

by Guenther Demetz (JIRA)

Deleted entities incorrectly reloaded within persistence context due to 2L cache -------------------------------------------------------------------------------- Key: HHH-4607 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4607 Project: Hibernate Core Issue Type: Bug Components: caching (L2) Affects Versions: 3.3.2 Environment: Hibernate3.3.2GA, SQLServer2008 used with COMMITED_READ isolation level Reporter: Guenther Demetz Attachments: TestCaseReloadAfterDelete.jar Normally hibernate_session.get(entityName, id) returns null if the concerning entity is scheduled for removal, indipendently if the current context was already flushed or not, and this is also correct.

Object entity = loadFromSessionCache( event, keyToLoad, options ); if ( entity == REMOVED_ENTITY_MARKER ) { log.debug( "load request found matching entity in context, but it is scheduled for removal; returning null" ); return null; } ... entity = loadFromSecondLevelCache(event, persister, options); if ( entity != null ) { ... return entity; } Afterwards doLoad attempts to load the entity from SecondLevelCache, where in meantime it may be put again due another concurrent session. N.B.: I believe the problem arises too if I would use JTA using the same transaction manager for both hibernate and 2LC (JBoss). best regards G.D. -- 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-7177) NullPointerException after persisting null NaturalId-values in combination with @NaturalIdCache

by Guenther Demetz (JIRA)

NullPointerException after persisting null NaturalId-values in combination with @NaturalIdCache ----------------------------------------------------------------------------------------------- Key: HHH-7177 URL: https://hibernate.onjira.com/browse/HHH-7177 Project: Hibernate ORM Issue Type: Bug Components: caching (L2) Affects Versions: 4.1.1 Reporter: Guenther Demetz Priority: Minor Since Steve has fixed HHH-7158 (see org.hibernate.test.naturalid.nullable.NullableNaturalIdTest), there's no NullPointerException anymore when persisting null values. But a NullPointerException raises again when annotating the entity class with @NaturalIdCache. Cause: {code:title=NaturalIdCacheKey.java constructor|borderStyle=solid} result = prime * result + type.getHashCode( value, factory ); // raises NPE when value is null {code} Proposed fix: {code:title=NaturalIdCacheKey.java constructor|borderStyle=solid} result = prime * result + (value == null ? 0 : type.getHashCode( value, factory )); {code} Testcase (see attachement): {code:title=org.hibernate.test.annotations.naturalid.NaturalIdOnSingleManyToOneTest.java|borderStyle=solid} @Test public void testManyToOnePersistMutableNaturalIdWithNullValue() { NaturalIdOnManyToOne singleManyToOne = new NaturalIdOnManyToOne(); Citizen c1 = new Citizen(); c1.setFirstname( "Emmanuel" ); c1.setLastname( "Bernard" ); c1.setSsn( "1234" ); State france = new State(); france.setName( "Ile de France" ); c1.setState( null ); singleManyToOne.setCitizen( c1 ); Session s = openSession(); Transaction tx = s.beginTransaction(); s.persist( france ); s.persist( c1 ); s.persist( singleManyToOne ); c1.setState( france ); s.flush(); // --> java.lang.NullPointerException below raises, test passes when removing @NaturalIdCache annotation on Citizen entity {code} -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-3644) Add support for "WITH UR" isolation clause on DB2

by Ricardo Fernandes (JIRA)

Add support for "WITH UR" isolation clause on DB2 ------------------------------------------------- Key: HHH-3644 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3644 Project: Hibernate Core Issue Type: Sub-task Components: core Affects Versions: 3.3.1 Environment: HIbernate 3.3.1 / DB2 9.x Reporter: Ricardo Fernandes The question is basically the same as Steve's, i.e. to force DB2 to use as few locks as possible on heavy load scenarios. Although some might consider the use of the WITH UR clause a bad approach (since it allows dirty reads), the fact is that there are some cases where this is in fact acceptable, such as computing the total amount of rows of a query (for information purposes) or producing a high-level listing of items with very little detailed info. The bottom line is: if I need to trade performance for extremely accurate data, I surely want to be able to decide when this should happen. I've already performed the changes that makes it possible to use both the FOR READ ONLY and the WITH UR clauses and I will be submitting a patch shortly so you can have a look at it. The strategy I've used was basically the following: 1. Added two new methods on the Dialect class: String getDatabaseReadOnlyString(String sql) - for adding the READ ONLY clause String getDirtyReadsString(String sql) - for adding the WITH UR clause 2. Changed the Query interface in order to allow the user to say whether he/she wants the query to allow dirty reads: Query setAllowDirtyReads(boolean allowDirtyReads); 3. Added a default implementation on the AbstractQueryImpl which initializes the flag a false 4. Added a similar attribute on the QueryParameters class 5. Changed the prepareQueryStatement() method of the Loader class (just after the useLimit part in order: a) Ask the dialect for the getDatabaseReadOnlyString() is there are no LockModes set (as did Steve) b) Ask the dialect for the getDirtyReadsString() is the queyParameters allows dirty reads. All the tests were well succeeded. Hope you find these changes, at least, worth looking at.
