[Hibernate-JIRA] Created: (HHH-2475) Split lib directory

by Christian Bauer (JIRA)

Split lib directory ------------------- Key: HHH-2475 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2475 Project: Hibernate3 Type: Improvement Components: build Reporter: Christian Bauer I've read again that Hibernate "requires 40 JARs" and that the fantastic Oracle reference implementation does not. This nonsense can only be stopped by splitting the lib/ subdirectory of our distribution into /lib/required, lib/optional, and lib/buildtime. Consider for 3.3. -- 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-2682) support for H2 in DialectFactory

by Dan Allen (JIRA)

support for H2 in DialectFactory -------------------------------- Key: HHH-2682 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2682 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.4.sp1 Environment: Hibernate 3 EJB3 JPA Reporter: Dan Allen For some reason, the H2 database is not included in the dialect factory map, even though there is a Hibernate dialect available for this database. Please add the following to org.hibernate.dialect.DialectFactory MAPPERS.put( "H2", new VersionInsensitiveMapper( "org.hibernate.dialect.H2Dialect" ) ); -- 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-2070) Improvement for DialectFactory

by Martin Renner (JIRA)

Improvement for DialectFactory ------------------------------ Key: HHH-2070 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2070 Project: Hibernate3 Type: Patch Components: core Versions: 3.2.0.cr4 Reporter: Martin Renner Attachments: DialectFactory.patch I would like to have more entries for autodetecting DB2 dialects. According to HHH-1467 I created a patch. At the moment, DialectFactory knows just "DB2/NT". We are currently using DB2Dialect for "DB2/6000" and "DB2/LINUX", but we would like to have Hibernate autodetect these dialects. So the patch simply adds two new lines to DialectFactory. It would be really helpful for us, if this patch would make it into 3.1.x and 3.2.x. The patch works for 3.1.3 and 3.2.0cr4. -- 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-2839) Don't use dummy dual table for hsqldb

by David Balažic (JIRA)

Don't use dummy dual table for hsqldb ------------------------------------- Key: HHH-2839 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2839 Project: Hibernate3 Issue Type: Patch Affects Versions: 3.2.5 Environment: hibernate 3.2.5 hsqldb 1.8.0.1 Reporter: David Balažic Attachments: HSQLDialect.diff This removes creation and use of a dual_foo table for each sequence. It is a simplification and also solves failures due to white space before the sequence name in the mapping XML : <id name="id" type="long" column="ID"> <generator class="sequence"> <param name="sequence"> seq_bar </param> will fail in the old code : "create table dual_" + sequenceName + " (zero integer)" which would give the following bad SQL : create table dual_ seq_bar (zero integer) -- 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-2849) Better error logging in IdentifierGeneratorFactory.java

by Antony Stubbs (JIRA)

Better error logging in IdentifierGeneratorFactory.java ------------------------------------------------------- Key: HHH-2849 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2849 Project: Hibernate3 Issue Type: Patch Components: core Affects Versions: 3.2.4.sp1, 3.3 Reporter: Antony Stubbs Priority: Minor Attachments: IdentifierGeneratorFactory.java.patch When specifying an incorrect id generator class in the hibernate mapping file, the following error messages are produced for the exception: Caused by: java.lang.RuntimeException: Exception building SessionFactory: could not instantiate id generator Caused by: org.hibernate.MappingException: could not instantiate id generator Caused by: org.hibernate.MappingException: could not interpret id generator strategy: com.x.persistence.sdfhibernate.SomeIdentityGenerator This doesn't show which mapping it's talking about. The patch I submitted slightly improves the message by adding the entity name: Caused by: org.hibernate.MappingException: could not instantiate id generator for entity com.x.persistence.hibernate.EntityClass admitedly I haven't tested it yet, because I am unable to get maven to build hibernate. but i'm working on that now (unable to download org.codehaus.mojo:antlr-maven-plugin:pom:2.0-SNAPSHOT) -- 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] Commented: (HHH-530) Allow application of filters on subqueries

by Shawn Clowater (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-530?page=co... ] Shawn Clowater commented on HHH-530: ------------------------------------ First of all. Thanks for taking a look at this. Even if it is only for 3.3, I'll manually patch 3.2.6 (when it arrives) if I have to. Hopefully, it's as simple a change as I've boiled it down to for the short term but I've tested it on a query that had at least 3 subqueries with filters at multiple levels for a grand total of 94 parameters (eek) and it sorted itself out. The original patch was fancier but I think it failed in certain cases and of course was no longer relevant. As for the mixed positional/named it seems to be restricted right at the parser level before it even gets to the parameter processing so that was good enough for me as my change doesn't seem to affect or change that behavior as far as I can tell. But, it looks like you're saying that there are cases where this doesn't hold true? Also, I stumbled across some class (I forget the name) that it looked like you had future use for it with the filtering aspect of things but again, for the short term, it would be nice if the functionality at least worked even if it wasn't what will be in the grand vision. Bear in mind that the SubqueryExpression also needs to be modded in order for the filters to be passed to the CriteriaJoinWalker. This is what I'm using at the moment as the current state of the world passes in new HashMap() for the enabled filters. CriteriaJoinWalker walker = new CriteriaJoinWalker( persister, innerQuery, factory, criteriaImpl, criteriaImpl.getEntityOrClassName(), ((CriteriaImpl) criteria).getSession().getEnabledFilters(), innerQuery.getRootSQLALias()); > Allow application of filters on subqueries > ------------------------------------------ > > Key: HHH-530 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-530 > Project: Hibernate3 > Issue Type: Patch > Components: core > Reporter: Gavin King > Assignee: Steve Ebersole > Fix For: 3.3 > > Attachments: HHH-530.patch, hibernate_filter_fix-3.0.5.patch, hibernate_filter_fix-3.0.5_14.patch > > > Currently filter conditions are applied in subselects, they should not be. -- 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
