[Hibernate-JIRA] Created: (HHH-3818) Hibernate/JBC integration doesn't property handle Entity/CollectionRegionAccessStrategy evict

by Brian Stansberry (JIRA)

Hibernate/JBC integration doesn't property handle Entity/CollectionRegionAccessStrategy evict --------------------------------------------------------------------------------------------- Key: HHH-3818 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3818 Project: Hibernate Core Issue Type: Bug Components: caching (L2) Affects Versions: 3.3.1 Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: 3.3.x EntityRegionAccessStrategy and CollectionRegionAccessStrategy have evict(Object key) and evictAll() that say they must cause removal of items from the cache "immediately without regard for transaction isolation." The Hibernate/JBC integration is not properly handling this as the JBC removeNode calls it makes are not dealing with transactional issues. The integration needs to: 1) Perhaps suspend any ongoing tx (particularly since these calls are typically made from a tx Synchronization's afterCompletion() callback, when the tx is Status.COMMITTED and it isn't appropriate to call into the cache expecting the cache to incorporate the call into the transaction. (Alhthough I believe JBC handles this correctly by ignoring the tx, since it isn't ACTIVE). 2) Deal with the fact that the tx that is being committed is likely holding locks in JBC. This is the big issue. I believe dealing with this will a) require keeping state in the Hib/JBC integration layer's Region to track that an eviction has occurred but may not be reflected in JBC b) using JBC as a notification bus to propagate the fact of the eviction to other nodes c) attempting to evict the data from JBC locally, failing promptly in the face of lock conflicts d) including in any get() or putFromLoad() calls logic to check the state from a), again attempting to evict locally (with a very short timeout) if not yet evicted and not allowing calls to proceed into JBC until successful. -- 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: (BVAL-192) Add 'exclusive' boolean attribute to @DecimalMin/@DecimalMax constraints

by Jaro Kuruc (JIRA)

Add 'exclusive' boolean attribute to @DecimalMin/@DecimalMax constraints ------------------------------------------------------------------------ Key: BVAL-192 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-192 Project: Bean Validation Issue Type: Improvement Components: spec-general Affects Versions: 1.0 final Environment: Hibernate Validator 4.0.0.GA Reporter: Jaro Kuruc Attachments: patch.patch Hi, may I suggest to enhance @DecimalMin/@DecimalMax constraints with additional 'exclusive' boolean attribute? This would allow to define a constraints like: a positive non-zero decimal number @DecimalMin(value = "0.0", exclusive = true) a negative non-zero decimal number @DecimalMax(value = "0.0", exclusive = true) This makes sense when dealing with decimal numbers where one might want to allow a number regardless of the precision. @DecimalMin("0.0001") vs. @DecimalMin("0.000000001"), etc. To maintain backward compatibility, default value for new 'exclusive' boolean attribute should be false. -- 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-787) @UniqueConstraint annotation not creating unique indexes

by Avinash THM (JIRA)

@UniqueConstraint annotation not creating unique indexes -------------------------------------------------------- Key: ANN-787 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-787 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.1.GA Environment: hibernate-core 3.3.1GA, hibernate-annotations 3.4.0GA, DB2 version 9.1 Reporter: Avinash THM Priority: Minor Unique indexes are not being created when using @UniqueConstraint annotation. The tables are created properly with primary keys and foreign keys, but the unique indexes are not created. I have posted the issue in hibernate forum (http://forum.hibernate.org/viewtopic.php?t=991505&highlight=) but didnt get any reply. I have also seen a couple of posts for the same problem. can anybody help me out with this issue? -- 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-4857) Sharing some of the config info from Ejb3Configuration and SessionFactoryImpl

by Chris Baxter (JIRA)

Sharing some of the config info from Ejb3Configuration and SessionFactoryImpl ----------------------------------------------------------------------------- Key: HHH-4857 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4857 Project: Hibernate Core Issue Type: New Feature Components: core, entity-manager Reporter: Chris Baxter Priority: Minor In our system, we have each clients data in a separate DB instance. We're using JPA (via hibernate) on top of that to get at the data. The problem here is that for each client DB supported by one of our jboss servers, we have to have an instance of EntityManagerFactory compete with an Ejb3Configuration instance. Each config instance takes up around 20 MBs of permanent space, so if we have have 1000 client DBs supported by a jboss instance, it takes up a hugh amount of memory for information that will always be the same (the DB schemas are always the exact same in each client DB) across all EntityManagerFactory instances. So what I want to know is if there is a way to only have one instance of Ejb3Configuration that can be shared across all of the EntityManagerFactory instances that are spawning my EntityManagers. This would be huge as it would help me save many gigs of memory that never can be collected (old gen in jboss). I prototyped some changes locally to Ejb3Configuration (to allow an instance of AnnotationConfiguration to be supplied in the constructor, allowing sharing across all instanced of this class) and to SessionFactoryImpl (to share some of the properties like entityPersisters, classMetadata and such) and I was able to reduce the footprint to 20 MBs for the first DB and then under a MB for each additional DB. The changes I made were a bit quick and dirty though, just to see if it was possible. So I'm taking out this feature request to see if this is a piece of work that you guys can do (or I can contribute after refactoring to a more suitable approach) and integrate into the main code for hibernate-core and hibernate-entitymanager. Let me know if this is something you guys think to be a valuable addition. -- 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-3465) HiRDB Support

by Tomoto Shimizu Washio (JIRA)

HiRDB Support ------------- Key: HHH-3465 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3465 Project: Hibernate3 Issue Type: New Feature Components: core Affects Versions: 3.2.5 Environment: 3.2.5 + HiRDB V8 + Type4 JDBC Driver Reporter: Tomoto Shimizu Washio Attachments: hirdbdialect.patch I would like to contribute with a dialect for HiRDB, Hitachi's RDBMS. (For more information, please see http://www.hitachi.co.jp/Prod/comp/soft1/global/prod/hirdb/) I added 4 classes and slightly modified 2 existing classes as shown below. Please look at the documentation at the top of the patch for explanations. org.hibernate.dialect.HiRDBDialect (added) org.hibernate.dialect.UserFuncDeclParser (added) org.hibernate.dialect.DialectFactory (modified) org.hibernate.dialect.function.AnsiTrimEmulationFunction (modified) org.hibernate.dialect.function.AnsiTrimEmulationFunctionWithTrimstrs (added) org.hibernate.dialect.function.TypeQualifiedSQLFunction (added) You may think this code is relatively large as a dialect. It is because I also implemented user-defined function support. As HiRDB requires '?' parameters to be qualified by 'as <type>' in user-defined function invocations, I made a parser for the type declarations that the user specified in the properties file, and a renderer for the type qualifier. See javadoc comments of HiRDBDialect and UserFuncDeclParser for more details. This patch is created on Hibernate 3.2.5.ga and tested on HiRDB V8 with Type4 JDBC Driver. The example configuration for HiRDB is shown below: hibernate.dialect org.hibernate.dialect.HiRDBDialect hibernate.connection.driver_class JP.co.Hitachi.soft.HiRDB.JDBC.HiRDBDriver hibernate.connection.url jdbc:hitachi:hirdb://DBID=@HIRDBENVGRP=C:/hirdb.ini hibernate.connection.username hitachi hibernate.connection.password hitachi -- 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-3733) Introduce an annotation to disable ad-hoc null semantic of Hibernate components

by Vladimir Kovalyuk (JIRA)

Introduce an annotation to disable ad-hoc null semantic of Hibernate components ------------------------------------------------------------------------------- Key: HHH-3733 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3733 Project: Hibernate Core Issue Type: Improvement Components: core Reporter: Vladimir Kovalyuk see http://forums.hibernate.org/viewtopic.php?t=993972 For the model @Entity public class Person { private Address name = new Address(); ... @Embedded Address getAddress() {} } @Embeddable public class Address { public String getCity() {} public String getStreet() {} } the following xhtml excerpt causes NPE constantly when editing a person which address properties hasn't been filled in yet <h:inputText value="#{person.address.city}" /> I suggest introducing an annotation @Static which could be applied to Address class and lead to disabling null ad-hoc semantic on its instances. For some environments such as user interface this may be considered as the default behavior. I suggest introducing an Hibernate configuration parameter which would switch off the semantic. I would propose to consider embeddable classes as static mixins from OO design, not as just limited entities without identity. This point of view explains that embedded instance is a part of entity so it's lifecycle is the same as the entity's lifecycle. Thus constant presence of embeddable instance (property is never null) is the default behavior. Thus configuration parameter is "must have", not the thing which is "nice to have". >From the other hand null ad-hoc semantic is like dynamic mixins. So it would be nice to have a @Dynamic annotation to force this semantic for some components. -- 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
