[Hibernate-JIRA] Created: (HSHARDS-4) extend shard locking to criteria and query

by Max Ross (JIRA)

extend shard locking to criteria and query ------------------------------------------ Key: HSHARDS-4 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSHARDS-4 Project: Hibernate Shards Issue Type: New Feature Components: query Affects Versions: 3.0.0.Beta1 Reporter: Max Ross Assignee: Max Ross Fix For: 3.0.0.beta2 We currently give people the ability to lock the shard used for shard selection, but we should extend this to shard resolution, criteria, and query. The use case is a request that does all of its db work against a single shard. Shards should give the user the ability to perform some operation to determine what shard should be used and then lock in that shard so that all subsequent db access via the ShardedSession only uses that one shard. -- 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-538) Give @IndexColumn a default name

by Sven Meier (JIRA)

Give @IndexColumn a default name -------------------------------- Key: ANN-538 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-538 Project: Hibernate Annotations Type: Improvement Versions: 3.2.1 Reporter: Sven Meier Priority: Minor It would be great, if the @IndexColumn annotation had a default 'name'. This would support users (e.g. me ;) in their effort to keep persistence annotations clear of database specifics. Additionally @IndexColumn is a rather often used annotation and it's tedious to repeat the same information (i.e. the 'name') over and over again. I'd propose 'hibernate_index', similar to the defaults in net.sf.hibernate.id.TableGenerator. Preferably this default would come from NamingStrategy, but I'm not sure how stable this interface is supposed to 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

optimization patch based on pmd rules ------------------------------------- Key: HHH-2122 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2122 Project: Hibernate3 Type: Patch Environment: latest svn source Reporter: Xavier Le Vourch Priority: Minor Attachments: Optimizations.patch I've run pmd with a custom ruleset and made a few optimization changes: Double.valueOf(x).doubleValue() -> Double.parseDouble(x) append("x") -> append('x') x != null && x instanceof X -> x instanceof X list.toArray uses correctly sized array as argument new String(str) -> str if (expr == false) -> if (!expr) append(s1 + s2) -> append(s1).append(s2) loop over array to add to list -> list.addAll(Arrays.asList(<array>)) extra ; removed name.toLowerCase().equals("rowid") -> name.equalsIgnoreCase("rowid") use of System.arraycopy instead of loop I could break the patch in several parts if that makes it easier to analyze.

[Hibernate-JIRA] Created: (ANN-526) Property xyz has an unbound type - is that so?

by Sebastian Kirsch (JIRA)

Property xyz has an unbound type - is that so? ---------------------------------------------- Key: ANN-526 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-526 Project: Hibernate Annotations Type: Bug Versions: 3.2.1 Reporter: Sebastian Kirsch Priority: Minor Attachments: Hibernate ANN-526.zip I get this "Property reference has an unbound type and no explictit target entity" exception and I think this is not exactly true. I'm not sure if this is a bug or a feature requests though. Have a look at the attached files and read on. I guess the model ist pretty easy to understand. The AbstractGeneric allows my to have concrete entities referring to specifc other subclasses - as seen in ConcreteOther and ConcreteSelf. The test case "workingClasses" shows us that Hibernate may work with this model - note that the class AbstractGeneric itslef was NOT added to the configuration. Now for the problem: The class OtherEntity is a completly different entity, but it refers to instances of AbstractGeneric - to any subclass of it actually, as AbstractGeneric is obviously abstract. If you run the test case "otherClass" the first part states that Hibernate doesn't know AbstractGeneric - which is fine, so I add that class to the configuration and try to build a session factory again. Now we receive the beforementioned exception. That's the situation. So is AbstractGeneric really an unbound type? I'd say it is not - T has an upper bound which should be good enough to work with - we know the table and the PK... -- 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-480) Query by Example in annotation form

by M N G (JIRA)

Query by Example in annotation form ----------------------------------- Key: ANN-480 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-480 Project: Hibernate Annotations Type: New Feature Environment: jdk >= 1.5, hibernate >= 3, ant > 1.5 Reporter: M N G Priority: Minor Attachments: searchable.tar.gz Interested in adsorbing this framework I built? Takes all the work out of creating a Criteria. Similar to how Query by Example, this small framework I wrote builds Criteria from annotated pojos. A pojo is annotated to map hibernate bean mappings to methods. The annotated pojo's class is registered in the Registry, which uses reflecting to define the signatures to create the Criteria for the pojo. The values to search for are set in the pojo and the pojo is passed to the Builder. The Builder uses the registry to create the Criteria delimited by the values in the annotated pojo. Not entirely mature yet (does not support all Criteria Restrictions) and the handling of sorting results is a bit unwieldy. It works tho. Attached is a copy of the framework. It includes a unit test that kick starts a HSQL database to demostrate the framework. -- 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
