Tweaked the rendering of projection operations to always use the field based reference lookup to make sure the reference gets rendered aliased. Moved value calculation logic into FieldReference.

Generalized exception message matching to reflect the changed exception message in MongoDB 2.5.x that also works with previous versions of MongoDB.

Changed repositoryImplementationPostfix() in EnableMongoRepositories to "Impl" to be consistent with other EnableXXXRepositories annotations. Note that this change is of rather documenting nature, as the defaulting of the configuration is applied in DefaultRepositoryConfiguration.getImplementationPostfix() in Spring Data Commons.

Added a tiny Thread.sleep(…) to make sure the assertion works on fast machines. If the operations after the first step all happen within a millisecond, it will fail.
The target type lookup previously was unpredictable in cases two converters were registered for the same source type. We now use LinkedHashMaps to register the converters and also make sure that we prefer manually registered converters over the default ones.

Aggregations can now be constructed from a list of AggregateOperations. This simplifies the usage in cases where one has to conditionally in- or exclude AggregateOperations from an AggregationPipeline.

Slightly changed the way the the simple reference rendering for projections is implemented. Introduced an isAliased() method on Field to be able to determine whether the field reference has been renamed explicitly.
Original pull request: #90.
Introduced boolean isSynthetic() attribute to FieldReference to determine if the given reference points to a synthetic field, as this controls whether we render a simple include (1) or a concrete reference ($fieldName) E.g. isSynthetic() would be true for a field reference to _id.

DefaultIndexOperations is now able to detect that in contrast to what's currently documented in the MongoDB reference documentation, it apparently returns double values for the index direction.
Original pull request: #67.
The check for keywords in QueryMapper now selectively decides between checks for a nested keyword (DBObject) object and the check for a simple key. This allows the usage of criteria values starting with $ (e.g. { 'myvalue' : '$334' }) without the value being considered a keyword and thus erroneously triggering a potential conversion of the value.
Moved more logic for a keyword into the Keyword value object.
In our Querydsl MongodbSerializer implementation we now only inspect the MongoPersistentProperty for a field name if the given path is really a property path. Previously we tried to always resolve a persistent property even if the given path was an array index path, a map key or the like.
Added an additional section to chapter 7.3 that describes the parameter value binding when the @PersistenceConstructor annotation including a small usage example. Added a concrete example for the @Value annotation that uses SpEL.
Original pull request: #77.
GroupOperation gets the _id field now rendered as null if no group fields were added to the operation. Previously it was rendered as empty document (i.e. { }). While this was technically correct as well, we're now closer to what the MongoDB reference documentation describes.
Original pull request: #73.
Adjusted FieldProjection to generate an appropriate representation of included / excluded fields (namely :1 for included and :0 for excluded).
Polished guards to handle only _id is allowed to be excluded (DATAMONGO-758).
Original pull request: #76.
Aggregation pipelines now correctly handle nested field references in aggregation operations. We introduced FieldsExposingAggregationOperation to mark AggregationOperations that change the set of exposed fields available for processing by later AggregationOperations. Extracted context state out of AggregationOperation to ExposedFieldsAggregationContext for better separation of concerns. Modified toDbObject(…) in Aggregation to only replace the aggregation context when the current AggregationOperation is a FieldExposingAggregationOperation.

Added support for skipping elements for NearQuery in MongoTemplate. As mongodb currently (2.4.4) doesn't support he skipping of elements in geoNear-Queries we skip the unnecessary elements ourselves. We use the limit & skip information from the given query or an explicitly passed Pageable.
Original pull request: #64.
Added a reading converter to dump DBObject instances into a String directly to enable executing queries against MongoDB into a String version of the query result without marshaling the DBObject into a Map first.
Added appropriate overloaded methods to MongoOperations and MongoTemplate. Applied pull request from Chuong Ngo <chuong.h.ngo.ctr@mail.mil>.
Original pull request: #57.
Added new attribute type-mapper-ref to the mapping-converter element in spring-mongo-1.3.xsd in order to support the configuration of custom-type-mappers. Removed the unsupported attributes "mongo-ref" and "mongo-template-ref" from the mapping-converter element in spring-mongo-1.3.xsd because they are not considered anymore.
Updated MappingMongoConverterParser to be aware of the new attribute. Added examples for configuring a custom MongoTypeMapper the usage of @TypeAlias to the reference documentation.
Original pull request: #61.
Added a guard to Criteria#(and|or|nor)Operator to prevent wrapping $and, $or or $nor expressions in a $not expression as mongodb currently doesn't support this. Added test case to CriteriaTests to verify that not() works as specified.
Original pull request: #60.
Fixed using the actual field reference instead of the field name on resolving. Added equals(…) and hashCode() methods to value objects. Added unit tests for TypeBasedAggregationOperationContext.
Updated changelog, notice and readme. Upgraded to Spring Data Build parent 1.1.1.RELEASE. Upgraded to Spring Data Commons RC1. Switched to milestone repository. Updated links to the parts of the Spring Data Commons reference documentation.
Added test cases to ProjectionOperationUnitTests. Adjusted DSL for GroupOperation to be similar to ProjectionOperation. Introduced GroupOperationBuilder to GroupOperation to be able to define an alias for the current GroupOperation. Adjusted test cases in AggregationTests to the new DSL style accordingly. Added test cases to GroupOperationUnitTests for push and addToSet.
ProjectionOperationBuilder now implements AggregationOperation in order to be able support aliased as well as non alias projection operation expressions. Added test case for arithmetic operations to AggregationTests. Added Product domain class to be able to demonstrate some meaningful arithmetic operations. Applied changes from code review. Added internal private remove method to ProjectionOperation to allow previous operation to support aliasing.
Refined the way the aggregation pipeline gets rendered into a DBObject. More tests. Added $avg and shortcut methods to GroupOperations. Fixed ProjectionOperation to use 1 for implicit references. Made ProjectionOperation publicly visible. Added automatic result unwrapping. API consistency, tests, JavaDoc polish.
Added automatic field reference resolution which removes the need to have in depth knowledge on how aggregation steps structures the output.
Introduced AggregateOperationContext abstraction to hold the information of available fields for an aggregation step.
Introduced ContextConsumingAggregateOperation and ContextProducingAggregateOperation abstractions to be able to distinguish operations.
Updates test cases to reflect the API changes.
