[Hibernate-JIRA] Created: (HHH-6328) Hibernate's "Table" annotations does not cooperate well with custom quoting naming strategy

by Richard Eckart de Castilho (JIRA)

Hibernate's "Table" annotations does not cooperate well with custom quoting naming strategy ------------------------------------------------------------------------------------------- Key: HHH-6328 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6328 Project: Hibernate Core Issue Type: Bug Components: annotations Affects Versions: 3.6.5 Reporter: Richard Eckart de Castilho I have implemented a custom QuotingNamingStrategy that quotes table names, so that they are properly treated as case sensitive and to avoid issues with reserved names. I also have auxiliary "Table" annotations to have Hibernate create indexes on my behalf. Of course the table name is not quoted in these annotations: {code} @org.hibernate.annotations.Table(appliesTo="MyTable",indexes = { @Index(name="column1", columnNames="column2")}) {code} Now I get the exception: {noformat} org.hibernate.AnnotationException: @org.hibernate.annotations.Table references an unknown table: MyTable at org.hibernate.cfg.annotations.EntityBinder.processComplementaryTableDefinitions(EntityBinder.java:877) at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:733) {noformat} Debugging the issue, I find that the EntityBinder tries to match the quoted name against the "appliesTo" attribute of the Table annotation, but the value of this attribute is not processed by my custom QuotingNamingStrategy. Thus, the table cannot be found: {code} public void processComplementaryTableDefinitions(org.hibernate.annotations.Table table) { //comment and index are processed here if ( table == null ) return; String appliedTable = table.appliesTo(); Iterator tables = persistentClass.getTableClosureIterator(); Table hibTable = null; while ( tables.hasNext() ) { Table pcTable = (Table) tables.next(); // -=> Here the quoted name is compared to the unquoted name from "appliedTable" if ( pcTable.getQuotedName().equals( appliedTable ) ) { //we are in the correct table to find columns hibTable = pcTable; break; } hibTable = null; } if ( hibTable == null ) { //maybe a join/secondary table for ( Join join : secondaryTables.values() ) { if ( join.getTable().getQuotedName().equals( appliedTable ) ) { hibTable = join.getTable(); break; } } } if ( hibTable == null ) { throw new AnnotationException( "@org.hibernate.annotations.Table references an unknown table: " + appliedTable ); } if ( !BinderHelper.isEmptyAnnotationValue( table.comment() ) ) hibTable.setComment( table.comment() ); TableBinder.addIndexes( hibTable, table.indexes(), mappings ); } {code} I do believe that the value of the "appliedTo" attribute should be passed through the naming strategy before comparing against the table name. -- 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: (HSEARCH-821) Finalize SearchFactory API decisions

by Sanne Grinovero (JIRA)

Finalize SearchFactory API decisions ------------------------------------ Key: HSEARCH-821 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-821 Project: Hibernate Search Issue Type: Task Reporter: Sanne Grinovero Priority: Blocker When introducing HSEARCH-750 we created these methods: {code}org.hibernate.search.SearchFactory.openIndexReader(Class<?>...) org.hibernate.search.SearchFactory.closeIndexReader(IndexReader){code} An alternative idea would be to add a single indirection, as for example searchFactory.getReaderProvider().open / close This task is about taking a final decision on that matter, and review the SearchFactory API for other methods as well. -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HV-495) Many locks on AnnotatedElements

by Loïc DIAS DA SILVA (JIRA)

Many locks on AnnotatedElements ------------------------------- Key: HV-495 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-495 Project: Hibernate Validator Issue Type: Patch Components: validators Affects Versions: 4.2.0.CR1 Environment: GNU/Linux, JVM 6.0, Hibernate Validator 4.2.0.CR1 Reporter: Loïc DIAS DA SILVA Attachments: jmeter-graph.docx, patch-ldds.patch Hi all, we use Hibernate Validator 4.2.0-CR1 (previously Apache BVAL) for one of our API projects. All is working fine for our needs except one big issue recently discovered during JMeter tests. Several injectors make many requests from some Amazon cloud servers to our API and starting from a number of requests the response time begins to increase eavily, making a big jump from about 100ms in average to more than 5s. After investigating we have seen many locks in some AnnotatedElement methods (mainly getAnnotation). I've then made a little patch on hibernate in order to cache this kind of requests as i've not found any other cleaver/yet implemented way.. Since this patch all is working very well for us..

[Hibernate-JIRA] Created: (HHH-6790) Add option to SequenceStyleGenerator to prefer a "sequence per entity"

by Steve Ebersole (JIRA)

Add option to SequenceStyleGenerator to prefer a "sequence per entity" ----------------------------------------------------------------------- Key: HHH-6790 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6790 Project: Hibernate Core Issue Type: New Feature Components: core Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 4.1.0 Basically this is a RFE for a corollary to {{org.hibernate.id.enhanced.TableGenerator#CONFIG_PREFER_SEGMENT_PER_ENTITY}} for the {{org.hibernate.id.enhanced.SequenceStyleGenerator}}. Currently, when no sequence name is given the default name (hibernate_sequence) is used. So this option would force {{org.hibernate.id.enhanced.SequenceStyleGenerator}} to determine a sequence name when none is explicitly given based on the name of the entity. The logic would be very similar to {{org.hibernate.id.enhanced.TableGenerator#determineDefaultSegmentValue}} but leveraging {{org.hibernate.id.IdentifierGenerator#ENTITY_NAME}} instead of {{org.hibernate.id.PersistentIdentifierGenerator#TABLE}} -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-2614) Blob Length Set to 255 By Default With Derby DB

by Sean Sylvis (JIRA)

Blob Length Set to 255 By Default With Derby DB ----------------------------------------------- Key: HHH-2614 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2614 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.3 Environment: Apache Derby 10.2.2, Java 1.6.0 Reporter: Sean Sylvis When the (Hibernate) type "blob" is used in an object mapping file and a length is not specified, Hibernate converts this type as "blob (255)" to the Apache Derby database table definition. (This seems to be the same as the conversion behavior of a Java String to "varchar (255).") The same behavior results when using a CustomType that returns a Java SQL Types.BLOB. This is not the behavior I expected. Hibernate converts the same type as simply "blob" (which has a maximum length of 65535 bytes when no length is specified) when using MySQL version 5.0 (http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html). Furthermore, the Derby specification (http://db.apache.org/derby/docs/10.2/ref/rrefblob.html) states that a blob type without a length value will default to a length of 2M-1 bytes. I could not find a length specification for the Java SQL Blob type (http://java.sun.com/javase/6/docs/api/), but the current default length does seem to conform to other Hibernate type standards. That is, if a length is not specified, the length defaults to the maximum length defined for that type by the database. -- 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-3240) In Derby field type 'text' is converted to CLOB(255)

by Aleksander Rozman (JIRA)

In Derby field type 'text' is converted to CLOB(255) ---------------------------------------------------- Key: HHH-3240 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3240 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.1 Environment: Hibernate 3.1, Derby 10.3.2.1 Reporter: Aleksander Rozman Priority: Blocker When using type 'text' this is incorectly converted to CLOB(255). Derby has several long var char types which could be used instead, but instead it's defaulted to clob(255). I have taken a look at source from 3.1 and 3.2.6 (latest) and this code is still the same... I think that just little fix in DerbyDialect would be enough... I would try this myself but I am currently lacking time and resources. I hope this will be taken care of as soon as it gets... -- 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-5160) Error on binding values prepared statment in many-to-any relation

by wof (JIRA)

Error on binding values prepared statment in many-to-any relation ----------------------------------------------------------------- Key: HHH-5160 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5160 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.1, 3.3.2 Environment: Tested on Version 3.3.2 and 3.5.1 on Oracle, PostgreSQL and MySQL Reporter: wof A Collection of Entities is defined as a ManyToAny relation, e.g. @ManyToAny(metaColumn=@Column(name="C_OBJECT_TYPE")) @AnyMetaDef(idType="string", metaType="string", metaValues={ @MetaValue(targetEntity=Entity1.class, value="Entity1"), @MetaValue(targetEntity=Entity2.class, value="Entity2") }) @JoinTable(name="T_OBJECTS", joinColumns=@JoinColumn(name="C_OWNER_ID"), inverseJoinColumns=@JoinColumn(name="C_OBJECT_ID") ) private Set<EntityBase> objects = new HashSet<EntityBase>(); Adding to this set works without problems. Removing all elements from the set (i.e. setting the set to null or zero-sized), too. However, when one or more elements are removed from the set with at least one element remaining, an exception is thrown: org.hibernate.exception.GenericJDBCException: could not delete collection rows with the cause being java.sql.SQLException: Parameter index out of range (3 > number of parameters, which is 2). I have narrowed this problem to this: The mapping table consists of 3 columns, C_OWNER_ID, C_OBJECT_TYPE and C_OBJECT_ID. The generated SQL-statement to delete the rows is as folling: DELETE FROM t_objects WHERE c_owner_id=? AND c_object_id=? However, Hibernate (in org.hibernate.typ.AnyType) tries to bind the actual value for c_object_id with index 3 which causes the exception. I guess Hibernate expects c_object_type to be present in the statement. As workaround we changed nullSafeSet in AnyType to: public void nullSafeSet(PreparedStatement st, Object value, int index, boolean[] settable, SessionImplementor session) throws HibernateException, SQLException { Serializable id; String entityName; if (value==null) { id=null; entityName=null; } else { entityName = session.bestGuessEntityName(value); id = ForeignKeys.getEntityIdentifierIfNotUnsaved(entityName, value, session); } // metaType is assumed to be single-column type // <ORIGINAL CODE> /* if ( settable==null || settable[0] ) { metaType.nullSafeSet(st, entityName, index, session); } if (settable==null) { identifierType.nullSafeSet(st, id, index+1, session); } else { boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index+1, idsettable, session); } */ // </ORIGINAL CODE> // <PATCHED CODE> if ( settable==null || settable[0] ) { metaType.nullSafeSet(st, entityName, index, session); boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index+1, idsettable, session); } else if (settable==null) { identifierType.nullSafeSet(st, id, index+1, session); } else { boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index, idsettable, session); } // </PATCHED CODE> } best regards wof -- 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
