[Hibernate-JIRA] Created: (HHH-2592) force hibernate to generate use offset qeury when offset is zero

by Amir Pashazadeh (JIRA)

force hibernate to generate use offset qeury when offset is zero ---------------------------------------------------------------- Key: HHH-2592 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2592 Project: Hibernate3 Issue Type: Improvement Components: query-criteria, query-hql, query-sql Affects Versions: 3.2.3 Environment: Hibernate Core 3.2.3 + Hibernate Annotations 3.3.0 JDK 5.0 Oracle 10g r2 Reporter: Amir Pashazadeh Attachments: patch.zip I know this is mostly an Oracle issue, but believe me it is harder to fix it in Oracle! when the offset of a paged query is zero, Hibernate does not append offset part to query, but the result which is returned by oracle without the offset part, and result returned when offset is zero is different. so some records are retrieved in different pages, and some records (which must be in first page) are not retrieved at all. ---- the patch is included. (I've only included Oracle9Dialect which I used) -- 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-2586) Hibernate Serializable classes do not declare serialVersionUID

by Manuel Dominguez Sarmiento (JIRA)

Hibernate Serializable classes do not declare serialVersionUID -------------------------------------------------------------- Key: HHH-2586 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2586 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.3, 3.2.2, 3.2.1, 3.2.0.ga, 3.2.0.cr5, 3.2.0.cr4, 3.2.0.cr3, 3.2.0.cr2, 3.2.0 cr1, 3.1.3, 3.2.0.alpha2, 3.2.0.alpha1, 3.1.2, 3.1.1, 3.1, 3.1 rc3, 3.1 rc2, 3.1 rc 1, 3.1 beta 2, 3.1 beta 1, 3.0.5, 3.0.4, 3.0.3, 3.0.2, 3.0.1, 3.0 final, 3.0 rc 1, 3.0 beta 4, 3.0 beta 3, 3.0 beta 2, 3.0 beta 1, 3.0 alpha Environment: Not specific to any database, platform or Hibernate version. Reporter: Manuel Dominguez Sarmiento None of the Serializable classes in Hibernate declare serialVersionUID (see http://www.hibernate.org/hib_docs/v3/api/serialized-form.html#org.hiberna...). This is recommended practice for ALL classes that implement the Serializable interface (see Joshua Bloch's Effective Java - Item #54). Adding these fields is trivial and takes little effort, but is a great enhancement if you are serializing Hibernate classes. For instance, we upgraded from Hibernate 3.2.2 to 3.2.3 in our production servers. We serialize process state (which sometimes includes references to Hibernate-managed entities) every 30 seconds or so and on shutdown, so in the event of failures or re-deployment, the processes can continue where they left off. We had a huge surprise when deserialization failed completely because AbstractPersistentCollection had slightly changed between the 3.2.2 and 3.2.3 releases, and this caused the automatically-generated default serialVersionUID to change, even though the changes in the serialized form are compatible as far as we can tell. -- 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

However, when using JBoss 4.0.4.GA and MySQL 5.0.22, reading the property (getXXX()) always return false If I force hbm2sql to generate a tinyint column, the boolean works as I would have expected: <column name="myColumn" sql-type="tinyint"/> -- 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: (HHH-2153) Not possible to overwrite System property defaults with hibernate.properties (e.g. use cglib bytecode provider in jboss)

by Armin Haaf (JIRA)

Not possible to overwrite System property defaults with hibernate.properties (e.g. use cglib bytecode provider in jboss) ------------------------------------------------------------------------------------------------------------------------ Key: HHH-2153 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2153 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.ga Environment: JBoss 4.0.4GA, hibernate 3.2.0.ga Reporter: Armin Haaf It is not possible to set the bytecode provider by hibernate.properties, because jboss ejb3.deployer sets it in System.properties. System.properties is added to the GLOBAL_PROPERTIES in Environment.class after hibernate.properties and overwrites the values in hibernate.properties. A solution would be to change the order of adding the properties to GLOBAL_PROPERTIES. First add System.properties, then add hibernate.properties, to be able to overwrite as 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-2021) org.hibernate.cache.QueryKey has a fragile equals() method

by Kenny MacLeod (JIRA)

org.hibernate.cache.QueryKey has a fragile equals() method ---------------------------------------------------------- Key: HHH-2021 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2021 Project: Hibernate3 Type: Bug Components: core Versions: 3.1.3 Reporter: Kenny MacLeod Priority: Trivial This one is no great shakes, but the first line of QueryKey.equals() casts the argument to QueryKey without checking for its type. As such, the method is fragile. It should be consistent with CacheKey, which does an instanceof check before the cast. -- 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-2442) ClassCastException loading from second level cache

by Marcio Moraes (JIRA)

ClassCastException loading from second level cache -------------------------------------------------- Key: HHH-2442 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2442 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1, 3.2.2, 3.2.0.ga Environment: Linux 2.6.15-27-686 #1 SMP PREEMPT Fri Dec 8 18:00:07 UTC 2006 i686 GNU/Linux Reporter: Marcio Moraes Priority: Blocker I'm getting a error when using hibernate 3.2.2.ga with cache (JBoss-Cache) cluster. When hibernate get a entity from second level cache it confuses the arrays of values against array of types. So in some situations i got ClassCastException ... Looking up CacheEntry code at assemble method i saw: private static Object[] assemble( final Serializable[] values, final Object result, final Serializable id, final EntityPersister persister, final Interceptor interceptor, final EventSource session) throws HibernateException { //assembled state gets put in a new array (we read from cache by value!) Object[] assembledProps = TypeFactory.assemble( values, persister.getPropertyTypes(), session, result ); The issue is values (Serializeble[]) is in wrong order compared with persister.getPropertyTypes() (Type[]). If only one cache instance is running it doesnt occurs ... I am using Linux.
