New Secondary Selection tests for Replica Sets introduced
To correct a regression, make WriteConcern immutable (Otherwise you can mutate static presets like SAFE at runtime) * Reintroduced constructors which accept continueOnErrorForInsert args * To enable you to set continueOnErrorForInsert with the presets like SAFE, immutable "new WriteConcern like this with COEI changed" method added.
2.7.0-rc3 / 2011-10-31
changed if statement to improve readability.
JAVA-462: GridFSInputFile does not close input streams when constructed by the driver (greenlaw110)
Add closeStreamOnPersist option when creating GridFSInputFile
attempt to clean up and standardize writeConcern
throw exception if w is wrong type
fix cast exception in case W is a String
Documented continue on error better.
Close inputstream of GridFSInputFile once chunk saved
JAVA-461: the logic to spread requests around slaves may select a slave over latency limit
Reset buffer when the object is checked out and before adding back.
added MongoOptions test
use the socket factory from the Mongo for ReplicaSetStatus connections
2.7.0-rc2 / 2011-10-26
JAVA-459: smooth the latency measurements (for secondary/slave server selection)
JAVA-428: Fixed edge cases where slaveOK / ReadPreference.SECONDARY wasn't working
JAVA-444: make ensureIndex first do a read on index collection to see if index exists * If an embedded field was referenced in an index a hard failure occurred, due to triggering of the 'no dots in key names' logic via the insert. Moved code to use the lower level API method which permits disabling of key checks.
Introduced "bamboo-test" task which does NOT halt on failure to allow bamboo tests to complete and report properly (and various fixes)
added unit test for x.y ensureIndex.
2.7.0-rc1 / 2011-10-24
JAVA-434: replaced isEmpty() with 1.5 compatible alternative
JAVA-363: NPE in GridFS.validate
JAVA-356: make JSONParseException public
JAVA-413: intern dbref.ns
JAVA-444: query before insert on index creation.
JAVA-404: slaveOk support for inline mapreduce (routes to secondaries); changed CommandResult to include serverUsed, made readPref-Secondary set slaveOk query flag, toString/toJSON on Node/ReplicaSetStatus.
Import javax.net in an OSGi environment.
JAVA-428 - Support new ReadPreference semantics, deprecate SlaveOK
Added a skip method to ensure continueOnInsertError test is only run on Server versions 2.0+
JAVA-448 - Tailable Cursor behavior while not in AWAIT mode
Fixed non-await empty tailable cursor behavior to be more consistently inline with other drivers & user expectations. Instead of forcing a sleep of 500 milliseconds on "no data", we instead when tailable catch an empty cursor and return null instead. This should be more safely non blocking for users who need to roll their own event driven code, for which the sleep breaks logic.
JAVA-439: Check keys to disallow dot in key names for embedded maps
added getObjectId method.
add partial query option flag
JAVA-425 - Support MongoDB Server 2.0 getLastError Changes (j, w=string/number)
JAVA-427 - Support ContinueOnError Flag for bulk insert
JAVA-422 - Memoize field locations (and other calculated data) for LazyBSONObject
JAVA-421 - LazyBSONObject exhibits certain behavioral breakages
JAVA-420: LazyBSONObject does not handle DBRef
Fix & cleanup of Javadoc comments (kevinsawicki)
JAVA-365: Poor concurrency handling in DBApiLayer.doGetCollection
JAVA-364: MapReduceOutput sometimes returns empty results in a replica set when SLAVE_OK=true
JAVA-333: Allow bson decoder per operation (find/cursor)
JAVA-323: When executing a command, only toplevel object returned should be a CommandResult (not sub-objects)
