[Hibernate-JIRA] Created: (ANN-758) map key type no longer inferred correctly, throws exception at runtime

by David Mansfield (JIRA)

map key type no longer inferred correctly, throws exception at runtime ---------------------------------------------------------------------- Key: ANN-758 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-758 Project: Hibernate Annotations Issue Type: Bug Components: binder Affects Versions: 3.3.1.GA Environment: hib. 3.2, annotaions 3.3.1GA, em 3.3.1GA, oracle 10r2, tomcat 5.5, linux, spring 2.0 Reporter: David Mansfield Attachments: hib-anno-set-map-key-type.patch after upgrading from annotations 3.3.0GA to 3.3.1GA, my mapped collection (ManyToMany) is broken. i've identified the commit that broke it: http://fisheye.jboss.com/browse/Hibernate/annotations/trunk/src/java/org/... The issue is that unless the type is given now expliticly in the @MapKey's @Type, the code now assumes a 'Serializable' type, and attempts to deserialize an object stream from the database column value. the exact exception is: java.io.StreamCorruptedException: invalid stream header at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:764) at java.io.ObjectInputStream.<init>(ObjectInputStream.java:277) at org.hibernate.util.SerializationHelper$CustomObjectInputStream.<init>(SerializationHelper.java:252) at org.hibernate.util.SerializationHelper.deserialize(SerializationHelper.java:209) at org.hibernate.util.SerializationHelper.deserialize(SerializationHelper.java:240) at org.hibernate.type.SerializableType.fromBytes(SerializableType.java:82) at org.hibernate.type.SerializableType.get(SerializableType.java:39) at org.hibernate.type.NullableType.nullSafeGet(NullableType.java:163) ... The fix is simple: if @Type is NOT given in the @MapKey annotation, keep the old behavior which at least tries to set the type, even if it may not work in all situations. The attached patch fixes the problem for me. In my particular situation, the map key type is a java.lang.Enum. Here's what my annotated property looks like: @ManyToMany @JoinTable( name="chargeback_owner" ,joinColumns=@JoinColumn(name="person_id",referencedColumnName="person_id") ,inverseJoinColumns=@JoinColumn(name="owner_person_id") ) @MapKey(columns=@Column(name="owner_type_cd"),targetElement=ChargebackOwnerType.class) @Enumerated(EnumType.STRING) @Sort(type=SortType.NATURAL) private SortedMap<ChargebackOwnerType,Person> owners = new TreeMap<ChargebackOwnerType, Person>(); -- 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-2449) Lazy loading for one-to-one asociations

by jose (JIRA)

Lazy loading for one-to-one asociations --------------------------------------- Key: HHH-2449 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2449 Project: Hibernate3 Type: New Feature Components: core Versions: 3.2.2 Environment: Hibernate 3.2.2 Reporter: jose After read "Some explanations on lazy loading" and my tests I found a lossing feature in Hibernate (3.2.2). one-to-one with lazy="proxy"_____________________________________________ Hibernate ALWAYS launch selects to know if one-to-one is null or can be proxied. one-to-one with lazy="no-proxy"__________________________________________ Instrumentation allows to hibernate modify the getter to allows lazy loading on demand: * but allways initialize ALL no-proxy relations (with first getter call) -> must initialize ONLY the requested property * never auto-initialize FETCH joins, ALWAYS doit on demand (if opened session) -> must auto-initialize ONLY the FETCHED property note: Can submit a fix for this? How? NEW FEATURE: one-to-one with lazy="proxy" without multiple SELECTS______ If Hibernate adds join, for all one-to-one relations, to get the foreign-key of other tables, can check it to create a proxy or null. note: that hibernate adds joins for hierarchy, why not for one-to-one relations? This solution avoids: * 'multiple subselects' after first select * 'instrumentation' of bytecode -- 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-2646) Informix 10 dialect with BLOB/CLOB support

by Thomas Much (JIRA)

Informix 10 dialect with BLOB/CLOB support ------------------------------------------ Key: HHH-2646 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2646 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.4.sp1 Environment: Informix 10 Reporter: Thomas Much Priority: Minor We discovered that Informix 10 works well with mapping types "blob" and "clob" if we use our own dialect that's simply derived from the existing Informix dialect by adding the two missing types: public class Informix10Dialect extends InformixDialect { public Informix10Dialect() { super(); registerColumnType( Types.BLOB, "blob" ); registerColumnType( Types.CLOB, "clob" ); } } We suggest adding this new dialect to Hibernate Core. (This is similar to issue HHH-2523, but here "clob" is mapped, too.) -- 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-2059) Section 19.2 of the documentation does not show Ehcache as supporting clusters. It does.

by Greg Luck (JIRA)

Section 19.2 of the documentation does not show Ehcache as supporting clusters. It does. ----------------------------------------------------------------------------------------- Key: HHH-2059 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2059 Project: Hibernate3 Type: Bug Components: documentation Versions: 3.2.0 cr1, 3.2.0.cr2, 3.2.0.cr3, 3.2.0.cr4 Reporter: Greg Luck Priority: Minor Section 19.2 of the documentation does not show Ehcache as supporting clusters. It does. The only reason I am asking for this is that people are confused about it and are asking me questions over at the ehcache project. e.g. see the following email to the list. From: p.perrucci(a)gmail.com Subject: [ehcache-list] Using ehcache as a clustered cache in hibernate3 Date: 6 September 2006 6:29:21 PM GMT+10:00 To: ehcache-list(a)lists.sourceforge.net Hi all, current version of ehcache implements distributed caching but hibernate3 docs says that ehcache is not cluster safe.

[Hibernate-JIRA] Created: (HHH-3112) Upgrade EhCache dependancy to 1.2.4+

by Stevo Slavic (JIRA)

Upgrade EhCache dependancy to 1.2.4+ ------------------------------------ Key: HHH-3112 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3112 Project: Hibernate3 Issue Type: Improvement Components: caching (L2) Affects Versions: 3.2.5 Reporter: Stevo Slavic Priority: Trivial Hibernate is widely used in conjunction with Spring framework. Spring framework as of version 2.0 expects EhCache to be 1.2.4+. When using both EhCache 1.2.4+ and Hibernate 3.2.5.ga as dependency in same maven project but in different sub-projects, older EhCache 1.2.3 (current Hibernate 3.2.5.ga dependency) can overwrite dependency application has for newer EhCache ( http://forum.springframework.org/showthread.php?t=49956 ). If Hibernate would use 1.2.4+ EhCache there would be no need to specify separate EhCache dependency. -- 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-210) Support hbm xml mapping!

by Mark Stewart (JIRA)

Support hbm xml mapping! ------------------------ Key: HSEARCH-210 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-210 Project: Hibernate Search Issue Type: Bug Components: mapping Affects Versions: 3.0.1.GA Environment: All. Reporter: Mark Stewart I like annotations as much as the next guy but it's a complete non-starter for our business (and, I suspect, plenty of others) to add full text search to our existing apps via Hibernate Search if it means we must convert all our existing hbm.xml configurations into annotations. The regression testing alone would kill us. The Hibernate project has always been supremely pragmatic which is why I've filed this as a bug rather than a feature request. I don't think Hibernate would have been half as popular if it didn't support things like direct SQL and reverse engineering tools. I think Search would see a big boost if it could be easily added to existing applications. Please consider adding the needed syntax for xml mapping. At the very least an entry in the FAQ that explains the lacking is needed. -- 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-3031) Include "FOR READ ONLY" hint in non-locking DB2 statements

by Steve Finch (JIRA)

Include "FOR READ ONLY" hint in non-locking DB2 statements ---------------------------------------------------------- Key: HHH-3031 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3031 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.5 Environment: 3.2.5, DB2/UDB 8.1+ Reporter: Steve Finch As per the DB2 documentation: http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.i... The FOR READ ONLY clause indicates that the result table is read-only and therefore the cursor cannot be referred to in Positioned UPDATE and DELETE statements. FOR FETCH ONLY has the same meaning. For result tables in which updates and deletes are allowed, specifying FOR READ ONLY (or FOR FETCH ONLY) can possibly improve the performance of FETCH operations by allowing the database manager to do blocking. For example, in programs that contain dynamic SQL statements without the FOR READ ONLY or ORDER BY clause, the database manager might open cursors as if the FOR UPDATE clause were specified. It is recommended, therefore, that the FOR READ ONLY clause be used to improve performance, except in cases where queries will be used in positioned UPDATE or DELETE statements. A read-only result table must not be referred to in a Positioned UPDATE or DELETE statement, whether it is read-only by nature or specified as FOR READ ONLY (FOR FETCH ONLY). The aforementioned improvement can be achieved by applying "FOR READ ONLY" when other locking hints are not specified. Patch to be uploaded soon. -- 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
