1.0.x-dev

__clone() method no longer called when documents are instantiated via ClassMetadata::newInstance()

As of #956, ClassMetadata uses the Doctrine Instantiator library to create new document instances. This library avoids calling __clone() or any public API on instantiated objects. This is a BC break for
code that may have relied upon the previous behavior.

1.0.0-BETA11 (2014-06-06)

All issues and pull requests in this release may be found under the 1.0.0-BETA11 milestone.

Ensure cascade mapping option is always set

ClassMetadataInfo's handling of cascade options was refactored in #888 to be more consistent with ORM. These changes ensure that $mapping["cascade"] is always set, which is required by ResolveTargetDocumentListener.

Use Reflection API to create document instances in PHP 5.4+

PHP 5.4.29 and 5.5.13 introduced a BC-breaking change to unserialize(), which broke ODM's ability to instantiate document classes without invoking their constructor (used for hydration). The suggested work-around is to use ReflectionClass::newInstanceWithoutConstructor(), which is available in 5.4+. This change was implemented in #893.

1.0.0-BETA10 (2014-05-05)

All issues and pull requests in this release may be found under the 1.0.0-BETA10 milestone.

ResolveTargetDocumentListener

#663 added a new ResolveTargetDocumentListener service, which allows targetDocument metadata to be resolved at runtime. This is based on a corresponding class in ORM, which has existed since version 2.2. This promotes loose coupling by allowing interfaces or abstract classes to be specified in the owning model's metadata. The service will then resolve those values to a concrete class upon the ODM's request.

Improved support for differentiating identifier types and non-scalar values

ODM previously required that documents use scalar identifier values. Also, the identity map, which UnitOfWork uses to track managed documents, was unable to differentiate between numeric strings and actual numeric types. After internal refactoring in #444, it should now be possible to use complex types such as MongoBinData and associative arrays (i.e. hash type) and the identity map should no longer confuse strings and numeric types. Embedded documents and references are still not supported as identifier values.

Classes not listed in discriminator maps

When a discriminator map is used, ODM will store the object's short key instead of its FQCN in the discriminator field. Previously, ODM might leave that field blank when dealing with a class that was not defined in the map. ODM will now fall back to storing the FQCN in this case. This primarily affects embedded documents and references.

Criteria API

The base DocumentRepository class now implements the Selectable interface from the Criteria API in Doctrine Collections 1.1. This brings some consistency with ORM; however, ODM's PersistentCollection class does not yet support Selectable. This functionality was introduced in #699.

Read preferences and Cursor refactoring

ODM's Cursor class was refactored to compose the Doctrine MongoDB Cursor. It still extends the base class for backwards compatibility, but methods are now proxied rather than simply overridden. This solved a few bugs where the cursor states might become inconsistent.

With this refactoring, ODM now has proper support for read preferences in its query builder and the UnitOfWork hints, which previously only supported the deprecated slaveOkay option. Much of this work was implemented in #565.

DocumentRepository findAll() and findBy()

The findAll() and findBy() methods in DocumentRepository previously returned a Cursor object, which was not compatible with the ObjectRepository interface in Doctrine Common. This has been changed in #752, so these methods now return a numerically indexed array. The change also affects the magic repository methods, which utilize findBy() internally. If users require a Cursor, they should utilize the query builder or a custom repository method.

Lifecycle callbacks and AlsoLoad

The @HasLifecycleCallbacks class annotation is now required for lifecycle annotations on methods declared within that class to be registered. If a parent and child close both register the same lifecycle callback, ODM will only invoke it once. Previously, the same callback could be registered and invoked multiple times (see #427, #474, and #695).

The @AlsoLoad method annotation does not require @HasLifecycleCallbacks on the class in which it is declared. If the method considers multiple fields, it will only be invoked once for the first field found. This is consistent with how @AlsoLoad works for properties. Previously, the method might be invoked multiple times.

MongoBinData subtype change for BinDataType

BinDataType (type bin) now defaults to 0 for its MongoBinData subtype. The various binary type classes have all been refactored to extend BinDataType. BinDataType's previous subtype, 2, is available via the BinDataByteArrayType class (type bin_bytearray); however, users should note that subtype 2 is deprecated in the BSON specification.

Priming references

Builder::prime() now allows any callable to be registered, where previously only Closures were supported. The method will throw an InvalidArgumentException if the argument is not a boolean or callable. Boolean true may still be passed to utilize the default primer. Priming is now deferred until the very end of Query::execute(), so it will now apply to findAndModify command results.

The signature for primer callables has changed to:

function(DocumentManager $dm, ClassMetadata $class, array $ids, array $hints)

A ClassMetadata instance (of the class to be primed) is now passed as the second argument instead of the class name string. The reference field name, which was formerly the third argument, has been removed.
