[Hibernate-JIRA] Created: (HHH-3502) getIdentifierMethod of BasicLazyInitializer does not match if method invoked through an interface with different return type

by Sean Bridges (JIRA)

getIdentifierMethod of BasicLazyInitializer does not match if method invoked through an interface with different return type ---------------------------------------------------------------------------------------------------------------------------- Key: HHH-3502 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3502 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.3.1 Reporter: Sean Bridges Priority: Minor I have an entity interface, public interface IEntity { public Object getId(); } and I have an entity, say User that implements this interface with an id method @Id public Long getId() { return id; } I can call getId() on an uninitialized proxy with, user.getId() however, if I call getId() in this way, ((IEntity) user)).getId() I get org.hibernate.LazyInitializationException: could not initialize proxy - no Session Looking at the code, BasicLazyInitializer has these lines, else if ( isUninitialized() && method.equals(getIdentifierMethod) ) { return getIdentifier(); } the method.equals(getIdentifierMethod) returns false. The methods are not equal() because they have different return types (this is allowed in 1.5 with covariant return types). Hibernate should not use Method.equals(), but should instead use the code below (modified from Method.equals(Object)), public boolean equalsIgnoringReturnType(Method m1, Method m2) { if ((m1.getDeclaringClass() != m2.getDeclaringClass()) { return false; } if (m1.getName() != m2.getName()) { return false; } Class[] params1 = m1.getParameterTypes(); Class[] params2 = m2.getParameterTypes(); if (params1.length != params2.length) { return false; } for (int i = 0; i < params1.length; i++) { if (params1[i] != params2[i]) return false; } return true; } -- 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-2031) Add functions to Dialect that can disable use of schema and catalog parts -- for HSQLDB support

by Brian Holmes (JIRA)

Add functions to Dialect that can disable use of schema and catalog parts -- for HSQLDB support ----------------------------------------------------------------------------------------------- Key: HHH-2031 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2031 Project: Hibernate3 Type: Patch Components: core Versions: 3.1.3 Environment: This patch is against r9668 of /tags/v313/Hibernate3. Reporter: Brian Holmes Attachments: hibernate3-v313-support_schema_catalog_names.patch HSQLDB does not support the use of three part names, that is Tables with schema and catalog parts. This patch adds two functions to Dialect: supportsSchemaNames() and supportsCatalogNames(). Table.getQualifiedName() checks these values to decide whether to use or ignore the schema and catalog parts. By default these are enabled in Dialect. This patch only disables their use in HSQLDialect. This change is necessary for people who normally use Schema and Catalog names for access their primary database, but also use HSQLDB for Unit Testing. Without it, HSQLDB is unusable for Unit Testing because it fails on use of any catalog or schema names. -- 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-3644) Add support for "WITH UR" isolation clause on DB2

by Ricardo Fernandes (JIRA)

Add support for "WITH UR" isolation clause on DB2 ------------------------------------------------- Key: HHH-3644 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3644 Project: Hibernate Core Issue Type: Sub-task Components: core Affects Versions: 3.3.1 Environment: HIbernate 3.3.1 / DB2 9.x Reporter: Ricardo Fernandes The question is basically the same as Steve's, i.e. to force DB2 to use as few locks as possible on heavy load scenarios. Although some might consider the use of the WITH UR clause a bad approach (since it allows dirty reads), the fact is that there are some cases where this is in fact acceptable, such as computing the total amount of rows of a query (for information purposes) or producing a high-level listing of items with very little detailed info. The bottom line is: if I need to trade performance for extremely accurate data, I surely want to be able to decide when this should happen. I've already performed the changes that makes it possible to use both the FOR READ ONLY and the WITH UR clauses and I will be submitting a patch shortly so you can have a look at it. The strategy I've used was basically the following: 1. Added two new methods on the Dialect class: String getDatabaseReadOnlyString(String sql) - for adding the READ ONLY clause String getDirtyReadsString(String sql) - for adding the WITH UR clause 2. Changed the Query interface in order to allow the user to say whether he/she wants the query to allow dirty reads: Query setAllowDirtyReads(boolean allowDirtyReads); 3. Added a default implementation on the AbstractQueryImpl which initializes the flag a false 4. Added a similar attribute on the QueryParameters class 5. Changed the prepareQueryStatement() method of the Loader class (just after the useLimit part in order: a) Ask the dialect for the getDatabaseReadOnlyString() is there are no LockModes set (as did Steve) b) Ask the dialect for the getDirtyReadsString() is the queyParameters allows dirty reads. All the tests were well succeeded. Hope you find these changes, at least, worth looking at.
