ServerAddressPropertyEditor now only eventually fails if none of the configured addresses can be parsed correctly. Strengthened the parsing implementation to not fail for host-only parsing or accidental double commas.
Cleaned up integration tests for replica set configuration.
The type of the value returned for the total field of the timing map in map-reduce results has changed from Integer to Long as of MongoDB version 2.1.0 apparently. Changed MapReduceResults to accommodate either Integer or Long types.
So far URL instances were treated as entities and serialized as nested document. As there was no custom converter registered to re-instantiate the objects and URL does not contain a no-arg constructor, reading the instances back in resulted in an ugly exception in ReflectionEntityInstantiator. We now register a custom Converter to serialize URL instances as their plain toString() representation. This causes the reading working out of the box as the StringToObjectConverter registered by default uses the constructor taking a String on URL accidentally. To make sure this still works we added an explicit StringToURLConverter to implement symmetric conversions.
The raw result for a map-reduce operation might contain a complex element containing the output collection in case the original request configured an output database as option. Adapted the parsing of the output collection to accommodate both scenarios (plain String value as well as DBObject wrapper).
So far we have resolved DBRef values eagerly without inspecting the actual property type the would have to be assigned eventually. Now we simply skip the recursive resolve process if the property type (or component type, map value type) is DBRef actually.
The debug output now uses the already mapped query object when concatenating the log string. Improved applying the id after save operations by inspecting whether the object already has the id set before trying to set it. This could have caused problems in case you use a complex id and don't provide a custom converter as it can be serialized out of the box. Fixed minor glitch in MappingMongoConverter which was not really a bug as another path through the code has covered the scenario later on. Introduced SerializationUtils class that provides a method to safely serialize objects to pseudo JSON. Pseudo in the sense that it simply renders a complex object as { $java : object.toString() }. This is useful for debug output before the DBObject was mapped into Mongo-native types.
So far we've read empty collections and populated the property value of the Java object being created with Collections.emptySet(). This returns an unmodifiable Set so that further modifications fail with an UnsupportedOperationException. We now simply use new HashSet<Object>().
Upgraded to JUnit 4.10. Move to junit-dep dependency to allow cleaning up hamcrest dependencies. Use hamcrest-library ins tread of hamcrest-all. Upgrade to Mockito 1.9.0, use mockito-core instead of mockito-all. Upgrade to Spring Data Core 1.3.1.BUILD-SNAPSHOT. Upgraded to Querydsl 2.6.0. Upgraded compiler and Surefire plugin.
Expose the failOnWarnings property to be able to override it through a command line argument. Necessary as the Sonar build uses Clover which instruments source code and thus creates type dependencies, Bundlor complains about not being declared in template.mf.
Using List as return type for paginating methods didn't work for query methods currently. Fixed by inspecting the Pageable parameter potentially handed into them and restricting the result set accordingly.
Added a performance tests that tests two things. Write performance in a variety of WriteConcern configurations as well as write-read performance against WriteConcern.SAFE. The tests can be executed by running the Maven build with the performance-test profile. Fixed some performance hotspots discovered in the course of profiling the test case.
Added event listener that uses a java.validation.Validator to trigger validation on an entity before persisting it. This validation is enabled by default if the javx.validation API is present on the classpath. Added namespace attribute 'disable-validation' to allow disabling that auto enabling behavior.
When using the not() method combined with the regex(…) methods on Criteria we created an invalid query so far. Fixed the regex(…) method to always transform the regex expressions and options into a Pattern instance and render that according to the $not state.
SimpleMongoDbFactory now only closes the Mongo instance if it created it itself. Removed public getter for WriteConcern and hold a UserCredentials instead of its parts. Uses improved UserCredentials API introduced in DATACMNS-142.
Removed UUIDToBinaryConverter and BinaryToUUIDConverter as the MongoDB Java driver can handle it itself. Added UUID as Mongo-simple type. Added integration test for reading and writing a UUID property.
Added toDBRef(…) method to MongoWriter to be able to create a DBRef representation of an object. Polished DBRef creation implementation inside MappingMongoConverter. Removed collection and id attributes from @DBRef annotation as they have neither been documented nor used so far. Refactored MongoQueryCreator to be aware of the property and convert the given value into a DBRef if necessary.
Added a method to IndexInfo to allow asking the object whether it is an index with a given collection of fields. Refactored RepositoryIndexCreationIntegrationTest to use that API to be more safe against potential duplicate index definitions.
MongoQueryCreator used the outdated OrQuery class to concatenate parts with OR. Refactored the class to use the Criteria.orOperator(…) method. Removed OrQuery class as it is deprecated in the 1.0.x branch.
Refactored JavaConfig base class to reflect the XML namespace a bit more closely (esp. regarding configuration of custom converters and thus registering "simple" types). Prevent duplicate invocation of getUserCredentials(). Added JavaDoc to explain which configuration methods use which other ones to ease detailed configuration.
Updated Sonargraph architecture description file to include GridFS subsystem. Moved QueryMapper into convert subsystem. Polished MongoRepository interface. Let SimpleMongoRepository implement MongoRepository.
Fixed a ClassCastException that occurred because we didn't consider index information of geo indexes (they return "2d" as direction). Introduced new IndexField abstraction that supersedes the fieldSpec Map in IndexInfo.
The Spring container does not check nested generic types of the type parameter of ApplicationEvent<T>. As T is parameterized in our case as well (PersistentEntity<…, …>) we can code an event listener against that fully parameterized type but might run into ClassCastExceptions as we might get other implementations handed into the method at runtime. We now do an instanceof check to safely invoke checkForIndexes(…) only in case we get the correct event type.
When using a PropertyPlaceHolderConfigurer to set WriteConcerns on a MongoFactoryBean just like this:
<bean class="….mongodb.core.MongoFactoryBean">
<property name="writeConcern" value="${mongodb.writeConcern}"/>
</bean>
we might create invalid WriteConcerns as the BeanFactory will use the WriteConcern's constructor taking a String to create the instance by default. To make Spring use the valueOf(…) method in advance one needs to register either our already existing WriteConcernPropertyEditor or the newly introduced StringToWriteConcernConverter in Springs ConversionService.
MappingMongoConverter now rejects objects that would result in field keys containing a dot as we cannot reliably escape and unescape them without potentially wrecking correct keys on reading. However I added a property mapKeyReplacement that can be set to e.g. ~ to have all dots in map keys replaced with ~. This will of course cause ~ to be transformed into dots when reading. If further customization is necessary override potentiallyEscapeMapKey(…) and potentiallyUnescapeMapKey(…).
The reference in MongoRepositoryFactoryBean to MongoTemplate was unnecessary on the one hand and could cause problems in case the MongoTemplate is proxied as it can't be wired into the factory anymore then.
