[Hibernate-JIRA] Created: (HHH-2578) redesign SessionFactory building

by Steve Ebersole (JIRA)

redesign SessionFactory building -------------------------------- Key: HHH-2578 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2578 Project: Hibernate3 Issue Type: Improvement Components: core Reporter: Steve Ebersole Assignee: Steve Ebersole Priority: Critical Fix For: cfg-rework Currently a SessionFactory is built by throwing a bunch of stuff into a Configuration object, stirring it, letting it come to a boil, and then pulling out the SessionFactory. In seriousness, there are a few problems with the way we currently operate within a Configuration and how we use it to build a SessionFactory: The general issue that there is no "lifecycle" to when various pieces of information will be available. This is an important omission in a number of ways: 1) consider schema generation. currently we cannot even know the dialect when a lot of db object names are being determined. this would be nice because it would allow us to transparently handle table/column names which are also keywords/reserved-words in the dialect, for example. 2) static-ness of types and the type-mappings. Because we currently have nothing to which to scope them. Ideally a type instance would be aware of the SessionFactory to which it is bound. Instead, what we have now is to change API methods quite a lot of the time to add in the SessionFactory as a passed parameter whenever it is discovered that it is needed. 3) also, most (all?) of the "static" configuration parameters in Hibernate are currently required to be so because of their use from within these static types; thus scoping types would allow us to also scope those config parameters (things like bytecode-provider, use of binary streams, etc). Ideally what I see happening is a scheme where users build a org.hibernate.cfg.Settings (or something similiar) instance themselves. Additionally they would apply metadata to a registry of some sort (lets call it MetadataRegistry for now). Then in order to build a SessionFactory, they would supply these two pieces of information (via ctor? via builder?). The important aspect though is that the information in MetadataRegistry would not be dealt with until that point in time, which would allow us to guarentee that resolving schema object names, types, etc would have access to the runtime Settings (and specifically the dialect) -- 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-2544) Create the EntityPersisters in order based on Inheritance hierarchy

by Shawn Clowater (JIRA)

Create the EntityPersisters in order based on Inheritance hierarchy ------------------------------------------------------------------- Key: HHH-2544 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2544 Project: Hibernate3 Issue Type: New Feature Components: core Affects Versions: 3.2.3 Reporter: Shawn Clowater Priority: Minor I have a bit of what might seem to be an odd request. I had run into a scenario where filters on my mappings that were part of a Single Table hierarchy were not getting into the configuration and it turned out it was based on the order that the EntityPersisters were being created as we've doing some minor magic with Custom EntityPersisters for filters. In our case we have a filter template where the filter is pretty much the same for each class that implements it except for the table and key name used in the filter. So, rather than define this annotation everywhere (we had previously been using xdoclet to generate it for the hbm mappings) we pushed the logic into a Custom Persister. So, essentially as it is building the EntityPersister we intercept the PersistentClass before it calls the super() constructor and add our required filters on the PersistantClass (in its FilterMap) before it gets passed up. This is done like this because by the time it gets to the AbstractEntityPersister's constructor it uses the filterMap to construct the FilterHelper and then you're done as you have no access to change that after it is built. So, in the Inheritance case any subclasses that are built before the main root class will not have the filters that we inject during the construction of our Custom Entity Persisters. I have temporarily worked around it by changing the Subclasses getFilterMap() method to not only return the filters from the Parent class but also from the class itself. Now, normally you can't define the filter on the subclass but I can through the persister. What I'd like to do is: Make the persister class for the subclasses a 'standard' persister that doesn't add any filters to the subclass. Still have my root class' entity persister adding the filters. But have the Entity Persisters built in hierarchal order in the SessionFactoryImpl. Since they are being built in any given order right now, I can't see an issue with providing some order to them, something like the AnnotationBinder does. -- 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

NamingStrategy.classToTableName receives only class name, not a fully qualified name as stated in javadoc --------------------------------------------------------------------------------------------------------- Key: HHH-1976 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1976 Project: Hibernate3 Type: Bug Components: core Versions: 3.1.3, 3.2.0.cr2 Reporter: Lóránt Pintér I have a custom NamingStrategy that overrides classToTableName in EJB3NamingStrategy. Prior to upgrading to Hibernate 3.1.3, my NamingStrategy implementation received the correct classnames as documented in the javadoc at http://www.hibernate.org/hib_docs/v3/api/org/hibernate/cfg/NamingStrategy... Since then, it only receives the name of the class without the package specification.

[Hibernate-JIRA] Created: (HHH-2150) There are too many columns in the select statement with the Criteria API

by Slawek Trybus (JIRA)

There are too many columns in the select statement with the Criteria API ------------------------------------------------------------------------ Key: HHH-2150 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2150 Project: Hibernate3 Type: Improvement Components: query-criteria Versions: 3.2.0.ga Environment: Hibernate 3.2.0.cr2 PostgreSQL 8.1.3 Reporter: Slawek Trybus Using Criteria API brings on enclosing all columns from joined tables in generated select statement. It has big efficiency impact on DB especially if there are many joined tables (with many columns each) in a query. There is columns' limitation possible with the Projections API usage, but it makes received objects not fully fledged Hibernate entity objects. It would be good to have posibility to limit amount of columns in select statement to ones connected to entity we are interested in.

[Hibernate-JIRA] Created: (HHH-2640) Clob management and deadlock

by Samuel Emangard (JIRA)

Clob management and deadlock ---------------------------- Key: HHH-2640 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2640 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.0.ga Environment: JDK 1.5, Oracle 10g v2 Reporter: Samuel Emangard Priority: Trivial Attachments: Samuel.rar Mapping documents: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC '-//Hibernate/Hibernate Mapping DTD 3.0//EN' 'http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd'> <hibernate-mapping package="com.toluna.samuel.hibernate.emailtemplate"> <class name="EmailTemplate" table="EmailTemplate"> <id name="id" type="long"> <column name="template_id" not-null="true"/> <generator class="native"/> </id> <property name="name"> <column name="email_name" not-null="false"/> </property> <property name="htmlTextClob" type="clob"> <column name="html_Text" not-null="false"/> </property> <property name="plainTextClob" type="clob"> <column name="plain_Text" not-null="false"/> </property> </class> </hibernate-mapping> Extract also of my Java bean: ublic class EmailTemplate { private long id; private String name; private String plainText = " "; private String htmlText = " "; private Clob plainTextClob; private Clob htmlTextClob; ... Code of the test case: Session ss = HibernateUtil.getSessionFactory().getCurrentSession(); //S_LOGGER.debug("Number of current Hibernate sessions: "+ HibernateUtil.getSessionFactory().getStatistics().getSessionOpenCount()); ss.getTransaction().begin(); EmailTemplate et = (EmailTemplate) ss.load(EmailTemplate.class, new Long("299941536982302")); S_LOGGER.debug(et.getName()); Thread.sleep(5000); S_LOGGER.debug("BEFORE FLUSH"); ss.flush(); S_LOGGER.debug("AFTER FLUSH"); ss.getTransaction().commit(); The generated SQL : The load statement is always generated: /* load com.toluna.samuel.hibernate.emailtemplate.EmailTemplate */ select emailtempl0_.template_id as template1_0_0_, emailtempl0_.email_name as email2_0_0_, emailtempl0_.html_Text as html3_0_0_, emailtempl0_.plain_Text as plain4_0_0_ from EmailTemplate emailtempl0_ where emailtempl0_.template_id=? .... Depending on the implementation of the getter, the following update statement is generated: /* update com.toluna.samuel.hibernate.emailtemplate.EmailTemplate */ update EmailTemplate set email_name=?, html_Text=?, plain_Text=? where template_id=? Here is the getter: Clob getHtmlTextClob() { //1- //return Hibernate.createClob(htmlText != null ? htmlText : " "); //2- return htmlTextClob; } With 1- the update statement is generated With 2- the update statement is not generated Why? Extract of the setter: void setHtmlTextClob(Clob htmlTextClob) { this.htmlTextClob = htmlTextClob; try { if (htmlTextClob != null) { htmlText = HibernateUtil.getStringFromClob(htmlTextClob); //htmlText = "samuel"; } else htmlText = ""; } catch (SQLException e) { throw new RuntimeException(e); } catch (IOException e) { throw new RuntimeException(e); } } I have also another more critical issue which seems tied to the previous: If I write the following piece of test code instead of the one shown above: Session ss = HibernateUtil.getSessionFactory().openSession(); //S_LOGGER.debug("Number of current Hibernate sessions: "+ HibernateUtil.getSessionFactory().getStatistics().getSessionOpenCount()); EmailTemplate et = (EmailTemplate) ss.load(EmailTemplate.class, new Long("299941536982302")); S_LOGGER.debug(et.getName()); Thread.sleep(5000); S_LOGGER.debug("BEFORE FLUSH"); ss.flush(); S_LOGGER.debug("AFTER FLUSH"); As you can see in this piece of code i do not manage transactions explicitly and in that case my 2 java threads generated update statements which never ended: there was a deadlock on the DB. During the last test, If I still did not manage transactions explicitly but I modified the getter like that: Clob getHtmlTextClob() { return htmlTextClob; } Then neither update statements nor deadlock were generated. I wrote this piece of test code to reproduce deadlock I was facing on my Jonas server. Could you please help me to understand this behaviour?
