Create a Java agent to enfore method level validation (design by contract) -------------------------------------------------------------------------- Key: HV-432 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-432 Project: Hibernate Validator Issue Type: Task Components: engine Affects Versions: 4.2.0.Final Reporter: Hardy Ferentschik Fix For: 4.x Google released Contract for Java - http://code.google.com/p/cofoja/ - which is a Java implementations for Design by Contract. Googles version uses a set of annotations, an annotation processor and a runtime java agent (see their documentation). We have all the pieces for doing this as well. * We have the constraint annotations * We have an annotation processor (obviously it does something else now, but we know how to write one) * And we have Byteman I wonder whether we couldn't put these things together and create our own Contract for Java. -- 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: (HV-388) Support property level ScriptAssert

by jason shi (JIRA)

Support property level ScriptAssert ----------------------------------- Key: HV-388 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-388 Project: Hibernate Validator Issue Type: New Feature Components: engine Affects Versions: 4.1.0.Final Reporter: jason shi Assignee: Hardy Ferentschik Current hibernate validator's ScriptAssert can only defined on the Class level, not property level. In OVal,it can define the ScriptAssert at the property level,eg: {code} public class BusinessObject { @NotNull public String deliveryAddress; @NotNull public String invoiceAddress; // mailingAddress must either be the delivery address or the invoice address @Assert(expr = "_value ==_this.deliveryAddress || _value == _this.invoiceAddress", lang = "groovy") public String mailingAddress; } {code} With property level,we can get following benefit: 1. Can be used in single property validation, It's very useful in UI layer validation 2. The validation rule is close to the property definition, it's easy to manage In JSR303 spec, the ValueContext is not passed to the Contrain Validator as a parameter, so the validator can't get the "Current Bean" of the current property to be validated. The validation engine need to some special work to support this feature. OVal can do this, so it won't be a problem for hibernate validator. -- 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: (HV-356) Consider if issue when bean's hashCode() uses lazy-loaded property needs to be addressed in default event listener/validator implementation

by Roman Arkadijovych Muntyanu (JIRA)

Consider if issue when bean's hashCode() uses lazy-loaded property needs to be addressed in default event listener/validator implementation ------------------------------------------------------------------------------------------------------------------------------------------- Key: HV-356 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-356 Project: Hibernate Validator Issue Type: Task Components: validators Affects Versions: 4.1.0.Final Environment: Hibernate 3.5.3-Final, Spring 3.0.3.RELEASE, Hibernate Validator 4.1.0.Final Reporter: Roman Arkadijovych Muntyanu Assignee: Hardy Ferentschik Priority: Minor This issue has been created based on contributor's request in discussion https://forum.hibernate.org/viewtopic.php?f=9&t=1006194&start=0 related to the issue occurring when persisted object's hashCode() implementation uses lazily-loaded properties. This triggers "collection [...] was not processed by flush()" issue with default Hibernate Validator event listener (org.hibernate.cfg.beanvalidation.BeanValidationEventListener) and validator (org.hibernate.validator.engine.ValidatorImpl) implementations because of hashCode() usage in SingleThreadCachedTraversableResolver.buildHashCode(). The purpose of this task is to consider whether this is or is not an overlook in assumptions made in validator implementation. And depending on the result following outcomes are expected: * either create a separate task for addressing the issue in default validator implementation; * or provide suggestions and (if possible) examples on how the issue can be addressed at the framework user's site if lazily-loaded properties usage IS appropriate. -- 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-189) Bean Validation should use java.beans.PropertyDescriptor

by Brian (JIRA)

Bean Validation should use java.beans.PropertyDescriptor -------------------------------------------------------- Key: BVAL-189 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-189 Project: Bean Validation Issue Type: Bug Affects Versions: 4.0.0.Alpha1 Environment: Any Reporter: Brian Priority: Minor Right now, hibernate determines a matching getter and setters by matching methods that start with "get" and "set" or "is" and "set". But the spec says that "is" should only be considered when the type is little boolean. Hibernate should fail validation in this case because it doesn't match the spec: public Boolean isVariable() public Boolean setVariable() because in this case "is" should be "get" since it is not a little boolean. -- 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-197) validation of a persisted map

by tho gau (JIRA)

validation of a persisted map ----------------------------- Key: BVAL-197 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-197 Project: Bean Validation Issue Type: Bug Environment: hibernate-core 3.5.0-Beta-3 Validator 4.0.1.GA MySQL 5.1 Reporter: tho gau Attachments: mapValidation.zip Hi, I am trying to validate an entity that holds a Map<K, V> of other persisted entities (just checking wether the map holds some predefined values). I can validate it "by hand" using validator.validate() and my map is correctly filled at validation time However when validation framework is called by persistence callbacks, my map is always empty... I am using Validator 4.0.1.GA and hibernate-core 3.5.0-Beta-2 I tryed to pinpoint the problem and it seems that the map is not touched in the following method of AbstractType during the merge : {code} public Object replace( Object original, Object target, SessionImplementor session, Object owner, Map copyCache, ForeignKeyDirection foreignKeyDirection) throws HibernateException { boolean include; if ( isAssociationType() ) { AssociationType atype = (AssociationType) this; include = atype.getForeignKeyDirection()==foreignKeyDirection; } else { include = ForeignKeyDirection.FOREIGN_KEY_FROM_PARENT==foreignKeyDirection; } return include ? replace(original, target, session, owner, copyCache) : target; } {code} -- 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-5927) Performance risk: Suboptimal synchronization in org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan

by Strong Liu (JIRA)

Performance risk: Suboptimal synchronization in org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan --------------------------------------------------------------------------------------------------------- Key: HHH-5927 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5927 Project: Hibernate Core Issue Type: Improvement Components: core Reporter: Strong Liu Attachments: hotspot.png with Order Demo (real-life simulation attempt test app) I have noticed that there is thread contention on createNamesQuery() which sounds suspicious. After investigation it boils down to org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan. It serves as a cache (internal, not replacable) for queries using LRU algorithm (supplied from Apache utils). Generally speaking, blocking threads in any sort of caches indicates a problem. From about 2000 calls, 700 got blocked (which is also not nice for context switching). I guess, one of the problems is that there is exclusive synchronization in get method: public synchronized Object get(Object key) {...} which could be replaced by a more granular read-write lock. org/hibernate/engine/query/QueryPlanCache.java org/hibernate/util/SoftLimitMRUCache.java -- 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
