[Hibernate-JIRA] Created: (HHH-3722) MySql autogenerated index names may conflict with thoses generated by reveng

by Hugh Daschbach (JIRA)

MySql autogenerated index names may conflict with thoses generated by reveng ---------------------------------------------------------------------------- Key: HHH-3722 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3722 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.2.0.ga Environment: MySql 5.0, hibernate-3.2 compiled from SVN revision 12635. Reporter: Hugh Daschbach Attachments: hibernate-3.2.patch MySql automatically generates indexes for unique and primary key fields. If duplicate key generation is suppresed as suggested in http://opensource.atlassian.com/projects/hibernate/browse/HBX-1104, the "create index" generated by hbm2ddl should be suppressed to avoid "Duplicate key name" errors. The attached patch skips explicit index generation for MySqlInnoDB dialect. -- 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-3721) MySql creates multiple indicies when "unique" specified on both column specification and constraint

by Hugh Daschbach (JIRA)

MySql creates multiple indicies when "unique" specified on both column specification and constraint --------------------------------------------------------------------------------------------------- Key: HHH-3721 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3721 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.2.0.ga Environment: MySql 5.0, hibernate-3.2 compiled from SVN revision 12635. Reporter: Hugh Daschbach Priority: Minor Attachments: hibernate-3.2.patch MySql seems to duplicate indexes when "unique" is specified both on the column specification as a constraint. For example: create table groups ( id int unsigned not null unique auto_increment, groupname varchar(30) unique not null, primary key (id), unique (groupname) ) engine = InnoDB; show index from groups; +--------+------------+-------------+--------------+-------------+- ... | Table | Non_unique | Key_name | Seq_in_index | Column_name | +--------+------------+-------------+--------------+-------------+- ... | groups | 0 | PRIMARY | 1 | id | ... | groups | 0 | id | 1 | id | ... | groups | 0 | groupname | 1 | groupname | ... | groups | 0 | groupname_2 | 1 | groupname | ... +--------+------------+-------------+--------------+-------------+- ... Note four indexes instead of two. The attached patch suppresses the "unique" qualifier on the column specification emitted by hbm2ddl. It may be better to apply this to MySqlDialect instead of MySqlInnoDBDialect. Or I may be mistaken altogether. -- 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-3717) SINGLE_TABLE inheritance: PersistentCollectionChangeWorkUnit.java: string truncating is used to find a property name from a collectionEntry

by Michele Comitini (JIRA)

SINGLE_TABLE inheritance: PersistentCollectionChangeWorkUnit.java: string truncating is used to find a property name from a collectionEntry ------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-3717 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3717 Project: Hibernate Core Issue Type: Bug Environment: envers 1.1.0 GA Reporter: Michele Comitini in PersistentCollectionChangeWorkUnit.java string truncating is used to find a property name from a collectionEntry. It seems that if the entity is derived with SINGLE_TABLE inheritance this truncating is fault prone. I attached a quick patch that seems to fix the problem, but I think manipulating strings is still not too safe to find the correct property name... Here is an excerpt of code that happens to fail: @Entity @Versioned @Table(name = "notifica") @Inheritance(strategy=InheritanceType.SINGLE_TABLE ) @NamedQueries({ @NamedQuery(name="Notifica.all", query="from Notifica"), }) public class Notifica extends BaseCQOPEntity implements Persistent { private static final long serialVersionUID = -7096378249035298397L; @Id @GeneratedValue @XStreamAlias("idd") private Long id; @Where(clause="not(deleted=(1=1))") @OneToMany(fetch=FetchType.EAGER) @Cascade({}) private Set<Ruolo> ruoli = new HashSet<Ruolo>(); . . . } @Entity @Versioned @DiscriminatorValue(value="Pratica") public class NotificaPratica extends NotificaImpresa { private static final long serialVersionUID = 1L; . . . } -- 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-796) @Proxy annotation's reference documentation needs to improved

by Joonas Koivunen (JIRA)

@Proxy annotation's reference documentation needs to improved ------------------------------------------------------------- Key: ANN-796 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-796 Project: Hibernate Annotations Issue Type: Improvement Components: documentation Affects Versions: 3.4.0.GA Environment: Core 3.3.1.GA, Apache Derby Reporter: Joonas Koivunen I stumbled upon the problem documented for example here: http://www.hibernate.org/250.709.html, that you cannot just ask for the super-class and expect a child class' instance, even if for example toString() gives the correct answer. In http://www.hibernate.org/hib_docs/v3/reference/en/html/performance.html#p... the use of <sub-class class="..." proxy="...">...</subclass> is documented. From that I realized that was this @Proxy annotation that I never thought of using before. Looking at http://www.hibernate.org/hib_docs/annotations/reference/en/html/entity.ht... that documents @Proxy: 1) It talks about proxyClassName attribute, which doesn't exist (any more at least), it has been replaced with Class<?> proxyClass 2) It doesn't mention anything about you having to annotate every class in the hierarchy from Cat to DomesticCat with @Proxy(proxyClass=BusinessInterfaceForEachClass.class) If not all of the hierarchy are annotated with @Proxy it'll throw a MappingException complaining that proxyClass is not an interface or the class itself, which doesn't quite translate to "you need to annotate whole hierarchy." Is this error because of some defaulting to void.class in the upper hierarchy perhaps? -- 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-3715) NPE in HqlSqlWalker, if named parameter contains a "."

by Andreas Sahlbach (JIRA)

NPE in HqlSqlWalker, if named parameter contains a "." ------------------------------------------------------ Key: HHH-3715 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3715 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.1 Reporter: Andreas Sahlbach Priority: Minor Query used: select company from example.PersistentCompany as company join company.attributes as attr where attr.value like :id.krias With this query I got a NullPointerException in HqlSqlWalker (see Stacktrace below). After some debugging I changed my query to select company from example.PersistentCompany as company join company.attributes as attr where attr.value like :krias which works perfectly. I guess the parser misinterpretes the "." in the parametername as tries to resolve a "krias" property. The NPE occurs, because there is no "next sibling" for the "krias" node. I suggest to harden your code against such a parameter name. Error would be ok, if "." in parameter names are not allowed, but there should be no NPE which gives no real hint about the cause.

[Hibernate-JIRA] Created: (HHH-3714) Merging lazy bidirectional one-to-one association with CascadeType.MERGE from both sides does not work correctly.

by Tihomir Totev (JIRA)

Merging lazy bidirectional one-to-one association with CascadeType.MERGE from both sides does not work correctly. ----------------------------------------------------------------------------------------------------------------- Key: HHH-3714 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3714 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: Hibernate Core 3.3.1.GA Hibernate Annotations 3.4.0 GA Hibernate EntityManager 3.4.0 GA Hibernate Validator 3.1.0 GA Reporter: Tihomir Totev Attachments: merge_bug.zip If you merge in the session object that has mappedBy annotation it works fine, but when you merge the other object it is inserted twice in the database. Then "More than one row with the given identifier was found" is given, which is correct since it is really inserted twice. I'm attaching a test of this problem.
