ReactiveMongoOperations.withSession(…) no longer commits transactions if a transaction is active. ReactiveSessionScoped obtained through inTransaction() solely manages transactions and participates in ongoing transactions if a given ClientSession has already an active transaction. Remove ReactiveSessionScoped.executeSingle methods to align with ReactiveMongoOperations.
Add tests. Switch reactive tests to .as(StepVerifier:create) form. Extend documentation.

We now support Mongo Transactions through the reactive Template API. However, there's no reactive repository transaction support yet.
Mono<DeleteResult> result = template.inTransaction()
.execute(action -> action.remove(query(where("id").is("step-1")), Step.class));

Full editing pass of the Spring Data MongoDB reference guide. I also adjusted index.adoc to work with the changes I made to the build project, so that we get Epub and PDF as well as HTML.

Rename MongoDbFactoryBase to MongoDbFactorySupport. Add constructor to MongoTemplate accepting the new MongoClient type. Extend Javadoc. Switch tests to use the new MongoTemplate constructor.

We now accept MongoDB's new com.mongodb.client.MongoClient object to setup Spring Data MongoDB infrastructure through AbstractMongoClientConfiguration. The new MongoClient does not support DBObject anymore hence it cannot be used with Querydsl.
@Configuration
public class MongoClientConfiguration extends AbstractMongoClientConfiguration {
@Override
protected String getDatabaseName() {
return "database";
}
@Override
public MongoClient mongoClient() {
return MongoClients.create("mongodb://localhost:27017/?replicaSet=rs0&w=majority");
}
}

Slightly tweak method names. Document MongoDatabaseUtils usage in the context of MongoTransactionManager. Rename SessionSynchronization constants to align with AbstractPlatformTransactionManager. Slightly tweak Javadoc and reference docs for typos.

MongoTransactionManager is the gateway to the well known Spring transaction support. It allows applications to use managed transaction features of Spring.
The MongoTransactionManager binds a ClientSession to the thread. MongoTemplate automatically detects those and operates on them accordingly.
static class Config extends AbstractMongoConfiguration {
// ...
@Bean
MongoTransactionManager transactionManager(MongoDbFactory dbFactory) {
return new MongoTransactionManager(dbFactory);
}
}
@Component
public class StateService {
@Transactional
void someBusinessFunction(Step step) {
template.insert(step);
process(step);
template.update(Step.class).apply(update.set("state", // ...
};
});

We now convert List-typed predicates to List to BasicDBList to meet MongodbSerializer's expectations for top-level lists used for the $and operator.

Throw FileNotFoundException on inherited methods throwing IOException if resource is absent. Retain filename for absent resources to provide context through GridFsResource.getFilename(). Switch exists() to determine presence/absence based on GridFSFile presence. Extend tests.

We now use ReactiveIndexOperationsProvider to inspect and create indexes for MongoDB collections without using blocking methods. Indexes are created for initial entities and whenever a MongoPersistentEntity is registered in MongoMappingContext.
Index creation is now decoupled from the actual ReactiveMongoTemplate call causing indexes to be created asynchronously. Mongo commands no longer depend on the completion of index creation commands. Decoupling also comes with the aspect that ReactiveMongoTemplate creation/command invocation no longer fails if the actual index creation fails. Previous usage of blocking index creation caused the actual ReactiveMongoTemplate call to fail.
ReactiveMongoTemplate objects can be created with a Consumer<Throwable> callback that is notified if an index creation fails.

Remove mapReduce default methods in favor of adding variants through a fluent API at a later stage. Assert mapReduce arguments and remove subsequent null guards. Adapt tests.
Original pull request: #548.
Inherit fields from previous operation if at least one field is excluded. Extend FieldsExposingAggregationOperation to conditionally inherit fields.
Original pull request: #538.
We now set autogenerated Ids in Maps that are used as top-level entities. This allows transparent and persistent Map usage without requiring to use Document in application code. Previously, we only set autogenerated Ids in Document and persistent entity types.

Remove client side operating system check as operating system-dependant constraints depend on the server. Add check on whitespaces. Add author tags. Extend tests.
Adapt check in SimpleReactiveMongoDatabaseFactory accordingly. Remove superfluous UnknownHostException declaration in reactive database factory. Replace references to legacy types in Javadoc with references to current ones.
Original pull request: #546.
Remove unused final keywords from method parameters and unused variables. Add nullable annotations to parameters that can be null. Fix generics.
Original pull request: #547.
Remove DateFactory and split up tests.
Introduce dedicated Timezone abstraction and update existing factories to apply the timezone if appropriate. Update builders and align code style.
