Enhancements

  • datanucleus-core-29 - Provide ability for store plugins to load references of related objects and cache them in the ExecutionContext (to save later fetch)

  • datanucleus-core-430 - Move AutoStartMechanism helper code to org.datanucleus.store.autostart package

  • datanucleus-core-431 - Metadata : provide fast lookup of different type of member

  • datanucleus-core-432 - Move RDBMSStoreManager getCatalogName, getSchemaName to StoreManager

  • datanucleus-core-434 - Remove Lock object from StateManagerImpl

  • datanucleus-core-435 - EmbeddedMetaData : drop memberMetaData and just use members

  • datanucleus-core-436 - Drop datanucleus.jmxType of "default" (use "platform" instead)

  • datanucleus-core-437 - Offload StateManagerImpl savedPC, savedLoadedFields, savedPersistenceFlags into separate object

  • datanucleus-core-438 - Change StateManager for embedded cases to only allow one "owner"

  • datanucleus-core-439 - Offload StateManagerImpl "activity" into flags bits

  • datanucleus-core-440 - Load of 1-N BIDIR collection should store owner in StateManager of each element if owner field isn’t loaded by default.

  • datanucleus-core-441 - Backed SCO Collection wrappers can avoid datastore call on remove(element) if not in the cached collection

  • datanucleus-core-443 - L2 cache is not updated when stored field is instantiated or when not already present

  • datanucleus-core-444 - Avoid embedded objects being put in L1 cache

  • datanucleus-core-445 - Change embedded object handling to ignore lifecycle, since managed by owner object

  • datanucleus-rdbms-370 - Provide mechanism for 1-1 owned / N-1 FK relation to be marked to fetch the "PK" only and not instantiate (when not in FetchPlan)

  • datanucleus-rdbms-407 - Table lookups in DatabaseMetaData only use catalog/schema if user-defined but should take default for the database

  • datanucleus-rdbms-408 - Support H2 v2

  • datanucleus-rdbms-413 - Change List backing store code for indexed list to shift in bulk (single statement)

  • datanucleus-rdbms-416 - ListStore.removeAll() is inefficient for indexed list, should do single "nulling" of list indexes and minimal reorders

  • datanucleus-rdbms-417 - Fetch of relation at one side of 1-1 bi relation should store the id of the related object in the other side StateManager

  • datanucleus-rdbms-418 - Allow auto-fetch of (unselected) FK fields in fetch request

  • datanucleus-rdbms-420 - Provide fallback JDBC type=NUMERIC when MySQL doesnt provide for it

Bugs

  • datanucleus-core-27 - Update of embedded when using pessimistic txns can result in problem in dirty field handling

  • datanucleus-rdbms-406 - Updated the default for the DatastoreId.class definition; it should be a BigInt by default, from 5.2

  • datanucleus-rdbms-409 - Specification of column name in <primary-key> block doesnt use identifier case in checks
