[Hibernate-JIRA] Created: (HHH-3249) Enhanced TableGenerator should declare member variables as protected

by Tom Muldoon (JIRA)

Enhanced TableGenerator should declare member variables as protected -------------------------------------------------------------------- Key: HHH-3249 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3249 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.6 Reporter: Tom Muldoon As currently implemented, the org.hibernate.id.enhanced.TableGenerator class declares each member variable as private (instead of protected) which makes extending the class difficult at the very least. For what it's worth, I'm overriding the configure method to base the segment_value off of the "target_table" instead of the "segment_value" - doing so allows me to have one row for each of my entities each of which extend an abstract BaseEntity (which is the class in that defines the id column). Using the enhanced TableGenerator without extension creates one row only. -- 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-2686) Include a primary key in the sequence table used by id.enhanced.TableGenerator

by Matt Solnit (JIRA)

Include a primary key in the sequence table used by id.enhanced.TableGenerator ------------------------------------------------------------------------------ Key: HHH-2686 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2686 Project: Hibernate3 Issue Type: Improvement Affects Versions: 3.2.3 Environment: Mac OS X (Intel) 10.4.9, Java 1.5.0_07, Hibernate 3.2.3.ga, MySQL 5.0.24a Reporter: Matt Solnit Priority: Minor Attachments: TableGenerator.java.diff It would be great if the new TableGenerator used a primary key on the "sequence_name" column. This would most likely improve performance when you have a large number of "sequences" in the table. I attempted to provide a patch :-). -- 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-2806) Enhanced TableGenerator is not cluster-safe on MySQL (does not use correct table type)

by Matt Solnit (JIRA)

Enhanced TableGenerator is not cluster-safe on MySQL (does not use correct table type) -------------------------------------------------------------------------------------- Key: HHH-2806 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2806 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Mac OS X 10.4.10 (Intel), Java 1.5.0_07, MySQL 5.0.24a Reporter: Matt Solnit Priority: Critical The org.hibernate.id.enanced.TableGenerator.sqlCreateStrings() method does not include a call to Dialect.getTableTypeString(). This means that on MySQL, it will +always+ use MyISAM, even if the Hibernate dialect is "MySQL5InnoDBDialect". The result is that the FOR UPDATE lock has no effect, and the generator is not cluster-safe. In other words, multiple Hibernate applications can receive the same ID and get a primary key violation. -- 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-2477) lazy fetching ManyToOne produces inproper proxies when using single table inheritance strategy

by Daniel Nguyen (JIRA)

lazy fetching ManyToOne produces inproper proxies when using single table inheritance strategy ---------------------------------------------------------------------------------------------- Key: HHH-2477 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2477 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1 Environment: hibernate 3.2.1-GA, postgresql 8.1 Reporter: Daniel Nguyen Attachments: bug.zip I have entity base class Vehicle and entity class Car which extends Vehicle (using single table inheritance strategy). I also have entity class User which have single-ended @ManyToOne relation from User to Vehicle with lazy fetching. Now there is a Car instance "c" and User instance "u" with relation to "c". Lazily fetching vehicle from "u" results with proxy object "o" which is instanceof Vehicle but not instanceof Car as expected. So it's impossible cast "o" to Car or at least read any of Car's property from "o". This is serious problem when inheritance is extensively used because inproper proxy object remains in cache. To walkaround I'd have to resign with lazy fetching (much performance loss) or manually replace proxy object in cache. testing code: SessionFactory sf = null; Session s = null; Transaction tx = null; try { sf = cfg.buildSessionFactory(); s = sf.openSession(); tx = s.beginTransaction(); //create car Car car = new Car(); car.setIdVehicle(1); car.setAge(5); s.save(car); //create user of car User user = new User(); user.setIdUser(1); user.setVehicle(car); s.save(user); //make sure it is actually added s.flush(); // test 1 - works ok, because we loaded vehicle before user s.clear(); //clear cache Vehicle vv = (Vehicle)s.get(Vehicle.class, 1); User uu = (User)s.get(User.class, 1); //we know that user vehicle is actually a Car Car cc = (Car)uu.getVehicle(); // test 2 - fails, when using lazy fetching s.clear(); //clear cache User u = (User)s.get(User.class, 1); Vehicle v = u.getVehicle(); //we know that user vehicle is actually a Car //so we cast to Car but ClassCastException is raised!!! Car c = (Car)v; //let's check what's actual class of v System.out.println(v.getClass().getName()); System.out.println(v.getClass().getSuperclass().getName()); //result: // test.hibernate.Vehicle$$EnhancerByCGLIB$$12ce1883 // test.hibernate.Vehicle //but I expected: // test.hibernate.Car$$EnhancerByCGLIB$$xxxxx // test.hibernate.Car } finally { if (tx!=null) tx.rollback(); if (s!=null) s.close(); if (sf!=null) sf.close(); } -- 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-723) Impossible to bind a SortedMap collection

by Alexandre Dutra (JIRA)

Impossible to bind a SortedMap collection ----------------------------------------- Key: ANN-723 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-723 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.0.ga Environment: hibernate: 3.2.5.ga hibernate-annotations: 3.3.0.ga database: HSQL 1.8.0.7 Reporter: Alexandre Dutra Priority: Minor See http://forum.hibernate.org/viewtopic.php?t=976437 I have the following collection declared in a persistent class: @CollectionOfElements @Sort(type = SortType.NATURAL) @JoinTable(name = "delivery_option_price", joinColumns = @JoinColumn(name = "delivery_option_id")) private SortedMap<Float, MonetaryAmount> prices = new TreeMap<Float, MonetaryAmount>(); Hibernate fails to bind it to a database table. The stack trace is: java.lang.NullPointerException at org.hibernate.cfg.annotations.MapBinder.bindKeyFromAssociationTable(MapBinder.java:129) at org.hibernate.cfg.annotations.MapBinder.access$000(MapBinder.java:53) at org.hibernate.cfg.annotations.MapBinder$1.secondPass(MapBinder.java:83) at org.hibernate.cfg.CollectionSecondPass.doSecondPass(CollectionSecondPass.java:43) at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1130) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:316) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1286) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:915) ... A workaround to this is to explicitly specify the map key class by adding a org.hibernate.annotations.MapKey annotation: @org.hibernate.annotations.MapKey(targetElement = Float.class, columns = @Column(name = "WEIGHT")) Browsing the source code, I realized that the NullPointerException is being raised beacause the following method returns null in org.hibernate.annotations.common.reflection.java.JavaXCollectionType: public XClass getMapKey() { return new TypeSwitch<XClass>() { @Override public XClass caseParameterizedType(ParameterizedType parameterizedType) { if ( getCollectionClass().isAssignableFrom( Map.class ) ) { return toXClass( parameterizedType.getActualTypeArguments()[0] ); } return null; } }.doSwitch( approximate() ); } More specifically, the following expression seems misconstructed: getCollectionClass().isAssignableFrom( Map.class ) The correct expression would be: Map.class.isAssignableFrom( getCollectionClass() ) At least if, as I understand it, the goal is to determine whether the collection class is or is not a Map in anyone one of its implementations. The same applies to the getElementClass() method, in the same class. If my analyzis is correct, the bug might be very easy to fix, but maybe I'm underestimating its impacts. -- 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
