[Hibernate-JIRA] Created: (HHH-3965) Expose the ability to use varchar(max) or nvarchar(max)

by Ido Ran (JIRA)

Expose the ability to use varchar(max) or nvarchar(max) ------------------------------------------------------- Key: HHH-3965 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3965 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: Hibernate 3.4.0GA as provider for JPA 1.0 - SQL Server 2005 Database Reporter: Ido Ran Priority: Blocker I have an entity which needs to store long text field (at least 30,000 characters). I use SQL Server 2005 as back-end database. SQL Server varchar support up-to 8,000 characters in length of a field, or the reserved word MAX which indicate that the field length will be 2^31-1. I think that the class SQLServerDialect should be changed to have the following line in it's ctor: registerColumnType( Types.VARCHAR, 8001, "varchar(MAX)" ); this way, all String fields with length above 8000 will have varchar(MAX) as column type. -- 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-5492) PostInsertListener doing new insert works on Mysql/HSQLDB, but not on Oracle.

by Barry (JIRA)

PostInsertListener doing new insert works on Mysql/HSQLDB, but not on Oracle. ----------------------------------------------------------------------------- Key: HHH-5492 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5492 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.4 Environment: Oracle Database 10g Express Edition Release 10.2.0.1.0 and Oracle Database 11g Release 11.1.0.0.0 Reporter: Barry Attachments: EventListener-test.zip I'm trying to implement a hibernate event listener that inserts a new record every time a specific entity is updated, deleted or inserted. I've implemented a listener for post-insert, post-update, post-delete. Its a requirement that the new record is inserted in the same transaction as the one that originally triggered the update/deletion/insert. The relevant section of my listener looks like this (similar for postInsert & postDelete): {code} public void onPostUpdate(PostUpdateEvent event) { if (isAuditable(event.getEntity())) { saveAuditRecord(event.getSession()); } } private boolean isAuditable(Object entity) { return entity instanceof SomeEntity; } private void saveAuditRecord(Session session) { AuditRecord record = new AuditRecord(); record.setId(Double.doubleToLongBits(Math.random())); session.save(record); } {code} The listener is triggered for each event, but it seems as though the AuditRecord is not saved when using an Oracle database. Using MySQL or HSQLDB works fine. So my guess is that it has something to do with the Oracle dialect? I've attached a test case which demonstrates it failing (but you will need to connect to an Oracle DB :-)) Same result for Oracle XE and the full monty. -- 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-3527) Null Version Comparator for versioned class due to reuse of Second Level CacheDataDescriptionImpl

by Paul FitzPatrick (JIRA)

Null Version Comparator for versioned class due to reuse of Second Level CacheDataDescriptionImpl ------------------------------------------------------------------------------------------------- Key: HHH-3527 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3527 Project: Hibernate Core Issue Type: Bug Components: caching (L2) Affects Versions: 3.3.1 Environment: 3.3.1 GA, Postgres 8.3.3, EH Cache Reporter: Paul FitzPatrick Priority: Minor When the SessionFactoryImpl constructor builds the EntityPersister for classes, it consults a cache of entityAccessStrategies for all the known second level cache regions. If only some of the classes in that region have version tags, then it is possible the cached EntityRegionAccessStrategy will be created without a Version Comparator. Subsequent calls to load an object using a Criteria query failed with a NullPointerException (stack trace below). The line being executed is "return version!=null && comparator.compare(version, newVersion) < 0;" and in this case "version" is an Integer object and comparator is null. Not sure the appropriate solution. It would seem from an examination of the code that if the EntityRegionAccessStrategy is to be shared, then all classes in the second level cache region _must_ either all have a "version" column or all have no "version" column. Further, it seems implied that if they use a "version" column, then they must all use the exact same data type. If this is the case, then a better error check on the configuration data may be in order.

[Hibernate-JIRA] Created: (HSEARCH-511) Clean up orphaned lock files on startup

by Marc Schipperheyn (JIRA)

Clean up orphaned lock files on startup --------------------------------------- Key: HSEARCH-511 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-511 Project: Hibernate Search Issue Type: Improvement Components: engine Affects Versions: 3.2.0.CR1 Reporter: Marc Schipperheyn I have had several occassions when the MassIndexer failed to complete for some reason and I had to restart Tomcat. MassIndexer creates lockfiles for the indexes it is updating. These lock files remain after a restart and block MassIndexer from running again. I suggest that Hibernate Search during startup checks for the existence of lock files in the index directory and removes then if they are there. This prevents an administrator from having to go and do it manually which is a bummer in production. -- 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-230) Database Connective or @Unique

by Ken Egervari (JIRA)

Database Connective or @Unique ------------------------------ Key: HV-230 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-230 Project: Hibernate Validator Issue Type: New Feature Affects Versions: 3.1.0.GA Reporter: Ken Egervari Priority: Critical I find a common validation use case is checking to see if a field is unique to all those in the table, such as emails, isbns, usernames, keywords, etc. these fields may not be the primary key, but still need to be unique. It would be fantastic if hibernate validator implemented this. This is a common problem though because the domain class will need to have access the database. I dunno if there's an easy way to wire in a copy of sessionFactory to make this easy to write. Perhaps something like this: @Query( "select user from User user where user.emailAddress = :this.emailAddress and user.id != :this.id", message = "That Email is already being used by another user in the system" ) private String emailAddress; Basically the idea is that if @Query returns no results, then the validation constraint is good, and if returns more than 1 result, then it fails. Kind of like simpleJdbcTemplate.queryForMap() does within the Spring testing framework. That method causes the test to fail if no row is returned, because it expects 1 result. If it were possible to just say @Unique private String emailAddress; That would be extremely concise and would save people a ton of time. Of course, this requires some interoperability with Hibernate... but I think that's a good thing, no? Thanks for taking this into consideration. I'd appreciate an email letting me know how to do this in a clean way in 3.1.0 GA as it is as well if you would. Thank you. -- 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
