Rumpmonkey|Code monkeys in heat!

Here is the current feature list:

  • Added OnPreLoad & OnPostLoad Lifecycle Events
  • Added ThreadStaticSessionContext
  • Added <on-delete> tag to <key>
  • Added foreign-key=”none” since the Parent have not-found=”ignore”. (not relevant to SQL Server)
  • Added DetachedQuery
  • ExecuteUpdate support for native SQL queries
  • From Hibernate:
    • Ported Actions, Events and Listeners
    • Ported StatelessSession
    • Ported CacheMode
    • Ported Statistics
    • Ported QueryPlan
    • Ported ResultSetWrapper
    • Ported Structured/Unstructured cache
    • Ported SchemaUpdate
    • Ported Hibernate.UserTypes

    • Ported EntityKey
    • Ported CollectionKey
    • Ported TypedValue
    • Ported SQLExceptionConverter
    • Ported Session Context
    • Ported CascadingAction
• Breaking changes:
  • Changed NHibernate.Expression namespace to NHibernate.Criterion
  • Changed NHiberante.Property namespace to NHiberante.Properties
  • No AutoFlush outside a transaction - Database transactions are never optional, all communication with a database has to occur inside a transaction, no matter if you read or write data.
  • <nhibernate> section is ignored, using <hibernate-configuration> section (note that they have different XML formats)
  • Configuration values are no longer prefixed by “hibernate.”, if before you would specify “hibernate.dialect”, now you specify just “dialect”
  • IInterceptor changed to match the Hibernate 3.2 Interceptor - interface changed
  • Will perform validation on all named queries at initialization time, and throw if any is not valid.
  • NHibernate will return long for count(*) queries on SQL Server
  • SaveOrUpdateCopy return a new instance of the entity without change the original.
  • INamingStrategy interface changed
  • NHibernate.Search - Moved Index/Store attributes to the Attributes namespace
  • Changes to IType, IEntityPersister, IVersionType - of interest only to people who did crazy stuff with NHibernate.
  • <formula> must contain parenthesis when needed
  • IBatcher interface change
• Fixed bugs:
  • Fixing bug with HQL queries on map with formula.
  • Fixed exception when the <idbag> has a <composite-element> inside; inside which, has a <many-to-one>
  • Multi criteria doesn’t support paging on dialects that doesn’t support limiting the query size using SQL.
  • Fixed an issue with limit string in MsSql2005 dialect sorting incorrectly on machines with multiple processors
  • Fixed an issue with getting NullReferenceException when using SimpleSubqueryExpression within another subexpression
  • Fixed Null Reference Exception when deleting a <list> that has holes in it.
  • Fixed duplicate column name on complex joins of similar tables
  • Fixed MultiQuery force to use parameter in all queries
  • Fixed concat function fails when a parameter contains a comma, and using MaxResults
  • Fixed failure with Formula when using the paging on MSSQL 2005 dialect
  • Fixed PersistentEnumType incorrectly assumes enum types have zero-value defined
  • Fixed SetMaxResults() returns one less row when SetFirstResult() is not used
  • Fixed Bug in GetLimitString for SQL Server 2005 when ordering by aggregates
  • Fixed SessionImpl.EnableFilter returns wrong filter if already enabled
  • Fixed Generated Id does not work for MySQL
  • Fixed one-to-one can never be lazy
  • Fixed FOR UPDATE statements not generated for pessimistic locking
• Improvements:
  • Added Guid support for Postgre Dialect
  • Added support for comments in queries
  • Added Merge and Persist to ISession
  • Support IFF for SQL Server
  • IdBag now work with Identity columns
  • Multi Criteria now uses the Result Transformer
  • Handling key-many-to-one && not-found
  • Can now specify that a class is abstract in the mapping.
• Guidance:
  • Prefer to use the Restrictions instead of the Expression class for defining Criteria queries.
• Child projects:
  • Added NHibernate.Validator
  • Added NHibernate.Shards
  • NHibernate.Search updated match to Hibernate Search 3.0
• Criteria API:
  • Allow Inspection, Traversal, Cloning and Transformation for ICriteria and DetachedCriteria
    • Introduced CriteriaTransformer class
    • GetCriteriaByPath, GetCriteriaByAlias
  • Added DetachedCriteria.For<T>
  • Added Multi Criteria
  • Projections can now pass parameters to the generated SQL statement.
  • Added support for calling Sql Functions (HQL concept) from projections (Criteria).
  • Added ConstantProjection
  • Added CastProjection
  • Can use IProjection as a parameter to ICriterion
• Better validation for proxies:
  • Now supports checking for internal fields as well
  • Updated Castle.DynamicProxy2.dll to have better support for .NET 2.0 SP1
• SQL Lite:
  • Support for multi query and multi criteria
  • Supporting subselects and limits
  • Allowed DROP TABLE IF EXISTS semantics
• PostgreSQL (Npgsql):
  • Enable Multi Query support for PostgreSQL
• FireBird:
  • Much better overall support
• Batching:
  • Changed logging to make it clearer that all commands are send to the database in a single batch.
  • AbstractBatcher now use the Interceptor to allow the user intercept and change an SQL before it’s preparation
• Error handling:
  • Better error message on exception in getting values in Int32Type
  • Better error message when using a subquery that contains a reference to non existing property
  • Throws a more meaningful exception when calling UniqueResult<T>() with a value type and the query returns null.
  • Overall better error handling
  • Better debug logs
• Refactoring:
  • Major refactoring internally to use generic collections instead of the non generic types.
  • Major refactoring to the configuration and the parsing of hbm files.
• Factories:
  • Added ProxyFactoryFactory
  • Added BatchingBatcherFactory

This is the first post on my new blog.  I’d like to introduce myself:
