[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: (ANN-728) @NaturalId doesn't work with @Embeddable/@Embedded

by Kenny MacLeod (JIRA)

@NaturalId doesn't work with @Embeddable/@Embedded -------------------------------------------------- Key: ANN-728 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-728 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.1.GA Reporter: Kenny MacLeod Attachments: BugTestCase.java If I try to annotate an @Entity's field with @NaturalId, and that field happens to be @Embedded or @Embeddable, then hibernate barfs with org.hibernate.MappingException: Unable to find logical column name from physical name component in table BugTestCase$MyEntity at org.hibernate.cfg.Mappings.getLogicalColumnName(Mappings.java:514) at org.hibernate.cfg.IndexOrUniqueKeySecondPass.doSecondPass(IndexOrUniqueKeySecondPass.java:61) at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1136) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:324) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1292) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:859) See attached unit test as a demonstration.

[Hibernate-JIRA] Created: (HHH-2085) org.hibernate.event.def.DefaultLoadEventListener logs exception at info level

by Don Smith (JIRA)

org.hibernate.event.def.DefaultLoadEventListener logs exception at info level ----------------------------------------------------------------------------- Key: HHH-2085 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2085 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr2 Environment: Hibernate 3.2.0.cr2, MySQL 4.0.18 Reporter: Don Smith Priority: Minor Prior to schema generation, accessing a persistent object throws an exception, as expected. The org.hibernate.event.def.DefaultLoadEventListener logs the exception at the info level, which just adds noise to the application console, and prevents application exception handling (in my case it's valid if the table doesn't exist, so I just want to catch the exception and continue). This log statement should be removed, or moved to a debug or trace level, so it won't show up in normal execution. Code, from line 94 of org.hibernate.event.def.DefaultLoadEventListener: catch(HibernateException e) { log.info("Error performing load command", e); throw e; } -- 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-4808) SessionImpl.initializeCollection() does not release JDBC connection (if outside of a transaction)

by Martin Renner (JIRA)

SessionImpl.initializeCollection() does not release JDBC connection (if outside of a transaction) ------------------------------------------------------------------------------------------------- Key: HHH-4808 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4808 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2, 3.2.7 Reporter: Martin Renner Priority: Critical With {{ConnectionReleaseMode.AFTER_TRANSACTION}} (the default), Hibernate does not release the JDBC connection when resolving a lazily loaded collection, if this happens *outside* of an active transaction. First, I will describe, what happens if Hibernate executes a query outside of a transaction. Then I will describe how lazy collection loading behaves differently. When the method {{list}} of a query ({{QueryImpl.java}}) is getting called, Hibernate delegates to {{SessionImpl.list()}}. After having loaded the list, {{SessionImpl.list()}} calls {{SessionImpl.afterOperation()}}, which calls {{jdbcContext.afterNontransactionalQuery()}} (as there is no active transaction). This leads to {{ConnectionManager.afterTransaction()}} which releases the JDBC connection. This is exactly what I expect to happen. Now to the lazily loaded collection: {{Hibernate.initialize(collection)}} and {{person.getPets().size()}} both end up in {{SessionImpl.initializeCollection()}}. This call gets dispatched down to {{Loader.doQueryAndInitializeNonLazyCollections()}} and {{Loader.doQuery()}}. The important fact is, that {{ConnectionManager.afterTransaction()}} never gets called (like in the query-example above). The result is, that the JDBC connection is not released. IMHO resolving of a lazily loaded collection should behave like executing a query. {{SessionImpl.initializeCollection()}} should call {{SessionImpl.afterOperation()}} in the same way as {{SessionImpl.list()}} is doing this. I will attach a small demo application which shows the difference (concerning {{ConnectionManager}}) between queries and collections. -- 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-3307) HQL query translation in real SQL ignores the dialect class

by Thomas Schilf (JIRA)

HQL query translation in real SQL ignores the dialect class ----------------------------------------------------------- Key: HHH-3307 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3307 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.6 Environment: dialect file with special JoinFragment and a "transformSelectString" step Reporter: Thomas Schilf We're using a special dialect class for a database. In the dialect is defined a own JoinFragment and a "transformSelectString" step. All workes fine by loading objects over a Criteria class. The generated SQL string is wrong by using named queries (HQL). The SQL string is in normal ANSI-SQL. The SqlGenerator and QueryTranslatorImpl classes from hibernate don't use the dialect class. -- 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-3799) PersistentSet does not honor hashcode/equals contract when loaded eagerly

by Igor Vaynberg (JIRA)

PersistentSet does not honor hashcode/equals contract when loaded eagerly ------------------------------------------------------------------------- Key: HHH-3799 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3799 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Reporter: Igor Vaynberg Priority: Blocker Attachments: test.zip when persistent set is loaded eagerly in some situations it calls hashcode on its items before their field values are populated and then uses this incorrect hashcode to store them in the set. this makes set items inaccessible by any collection items that rely on hashcode such as contains(), remove(), etc. attached is a simple maven test project that reproduces the error, unzip and mvn test to run the test. -- 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-4699) String mapped ENUMs can't be loaded from CHARs only VARCHARS (fix is trivial)

by Pierce Wetter (JIRA)

String mapped ENUMs can't be loaded from CHARs only VARCHARS (fix is trivial) ----------------------------------------------------------------------------- Key: HHH-4699 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4699 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5 Environment: all Reporter: Pierce Wetter An enum persisted as a string to a CHAR column comes back with extra spaces appended, so then fails the Enum.valueOf() lookup. Fix is easy: Line 132 of EnumType.java, method nullSafeGet, change: return Enum.valueOf( enumClass, name ); to return Enum.valueOf( enumClass, name.trim() ); Which should be perfectly logical, because spaces are illegal in enum names anyways. -- 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
