  • …rily leaving the topology
    
    Changed ChangeTimeHeartbeatMsg to be able to send timestamps for a replica stopping. This is done by adding an event type to cover both normal heartbeat and temporarily offline replica.
    This allows RSs to compute medium consistency accurately by using the stop time from the originating server.
    Because of this change, incremented protocol version to v8.
    
    
    
    ProtocolVersion.java:
    Added REPLICATION_PROTOCOL_V8.
    Fixed javadocs by using lists.
    
    ByteArrayBuilder.java, ByteArrayScanner.java, ByteArrayTest.java: ADDED
    
    ChangeTimeHeartbeatMsg.java:
    Added eventType field + added isReplicaOfflineMsg().
    Made ctor private + added factory methods heartbeatMsg() and replicaOfflineMsg().
    Used ByteArrayBuilder and ByteArrayScanner.
    
    CTHeartbeatPublisherThread.java:
    In run(), on shutdown, handle sending a replica offline message.
    
    
    
    SynchronizationMsgTest.java:
    Added changeTimeHeartbeatMsgTest() and assertCTHearbeatMsg().
    Code cleanup + used static import for ProtocolVersion.
    
    
    
    DataServerHandler.java:
    Consequence of the change to StopMsg ctor.
    Extracted method publishStopMsg() for increased readability.
    
    ReplicationServerDomain.java:
    In processChangeTimeHeartbeatMsg(), added support for offline replica messages + declared DirectoryException checked exception.
    
    ServerHandler.java:
    Consequence of the change to ReplicationServerDomain.processChangeTimeHeartbeatMsg() checked exception.
    
    
    
    ChangeNumberIndexer.java:
    In initialize(), handle offline replicas.
    In moveForwardMediumConsistencyPoint(), now throw ChangelogException.
    In removeCursor(), now call resetNextChangeForInsertDBCursor().
    
    ChangeNumberIndexerTest.java:
    Expanded the emptyDBTwoDSsOneGoingOffline() test.
    
    
    
    JEChangelogDB.java, ReplicationDomainDB.java:
    In replicaOffline(), now throw ChangelogException and call ReplicationDbEnv.addOfflineReplica()
    Added ChangelogDBPurger.initiateShutdown().
    
    ReplicationDbEnv.java:
    Added OFFLINE_TAG constant, toReplicaOfflineEntry(), addOfflineReplica() and putInChangelogStateDB(), toByteArray()().
    In decodeChangelogState(), handle offline replica information.
    Changed several method signature to use Entry<byte[], byte[]> instead of Entry<String, String>.
    
    ReplicationDbEnvTest.java:
    Fixed indentation + added tests.
    
    ChangelogState.java:
    Added offlineReplicas field + addOfflineReplica() and getOfflineReplicas() + changed toString() to display it.
    
    
    
    StopMsg.java:
    Added toString().
    
    JEReplicaDBCursor.java:
    Improved comments and javadocs.

  • It seems unnecessary to have a msgQueue on top of JE since JE's already has a builtin cache that handles the same responsibility.
    This improvement removes the JEReplicaDB.msgQueue and the associated flushing thread to save on memory and resources.
    
    Code cleanup in JEChangeNumberIndexDB after CR-3388.
    
    
    JEReplicaDB.java:
    Does not implement Runnable anymore.
    Removed fields msgQueue, queueSizeBytes, queueMaxBytes, thread, flushLock.
    Added and used shutdown field to compensate for removing the thread field.
    Removed methods collectAllPermits(), flush(), run() and stop().
    In shutdown(), used AtomicBoolean.compareAndSet().
    
    ReplicationDB.java:
    Renamed addEntries(List<UpdateMsg>) to addEntry(UpdateMsg).
    
    JEReplicaDBTest.java:
    Removed now unnecessary waitChangesArePersisted().
    
    
    JEChangelogDB.java:
    In shutdown(), enforced threads joining + called Thread.interrupt() to ensure shutdown. This prevents message about unclosed cursors in integrated unit tests.
    
    ReplicationServer.java:
    Removed getQueueSize().
    
    
    JEChangeNumberIndexDB.java:

  • The bug was due to a very complex interaction between various components. Here is a scenario and explanation:
    1- the change number indexer has no more records to proceed, because all cursors are exhausted, so it calls wait().
    2- a new change Upd1 comes in for an exhausted cursor, medium consistency cannot move.
    3- a new change Upd2 comes in for a cursor that is not already opened, medium consistency can move, so wake up the change number indexer.
    3- on wake up, the change number indexer calls next(), advancing the CompositeDBCursor, which recycles the exhausted cursor, then calls next() on it, making it lose its change. CompositeDBCursor currentRecord == Upd1.
    4- on the next iteration of the loop in run(), a new cursor is created, triggering the creation of a new CompositeDBCursor => Upd1 is lost. CompositeDBCursor currentRecord == Upd2.
    
    The problem comes from two parts:
    - CompositeDBCursor consumes next change from a cursor (which completely forget about this change) and stores it itself
    - ChangeNumberIndexer manages recycling/creating cursors on its own and recreates CompositeDBCursor when a new cursor is created.
    
    The fix required:
    - Preventing CompositeDBCursor from consuming changes from underlying cursors until it can forget about this same change itself.
    - Ensuring only ChangeNumberIndexer handle recycling the cursors it owns instead of having both CompositeDBCursor and ChangeNumberIndexer trying to do it. It is also more performant to let ChangeNumberIndexer manage its cursors.
    
    
    
    CompositeDBCursor.java:
    Added recycleExhaustedCursors field to tell the composite whether it can recycle the cursors itself or not (recycling the cursors is currently needed for persistent searches on the changelog, maybe will we be able to remove it in the future, that would simplify the code a lot).
    Modified the ctor to pass in value of recycleExhaustedCursors.
    Removed currentRecord and currentData fields, replaced by reading the record and field on the first entry in the cursors SortedMap.
    Added state field to ensure the first call to next() does not consume the first change in the cursors SortedMap.
    
    ChangeNumberIndexer.java:
    ChangeNumberIndexer now manages alone the cursors recycling and creation and recreates the CompositeDBCursor when needed.
    In run(), removed the now unneeded call to next() after the wait.
    Added recycleExhaustedCursors().
    
    JEChangelogDB.java:
    Consequence of the change to CompositeDBCursor. Kept old recycling behaviour.
    
    
    ChangeNumberIndexerTest.java:
    Added emptyDBTwoDSsDoesNotLoseChanges() to cover the case being fixed by current commit.
    Renamed test methods dropping the "Initial" when it was not adding much to the test comprehension.
    
    CompositeDBCursorTest.java:
    In newUpdateMsg(), added toString() implementation to help debug.
    Removed recycleTwoElementCursorsTODOJNR().
    In recycleTwoElementCursors(), changed the tests a bit to match the changes to CompositeDBCursor.

  • …beat from known replicas
    
    On startup, if a replication server knows about several replicas, then it must wait to receive some sort of alive information for each of them before being able to move the medium consistency forward.
    Changes or heartbeats received after replication server started are acceptable.
    Likewise, changes that would have been received before the replication server stopped are also acceptable.
    
    This was fixed on replication server startup, by initializing the lastAliveCSN for each known replica, with the oldest possible CSN (timestamp == 0).
    Then when checking if the medium consistency can move forward, if no medium consistency is set, then the lastAliveCSN for each known replica must have a timestamp != 0.
    
    
    ChangeNumberIndexer.java:
    In canMoveForwardMediumConsistencyPoint(), call allInitialReplicasArePastOldestPossibleCSN() if the medium consistency CSN is not set.
    Added methods oldestPossibleCSN(), allInitialReplicasAreAlive().
    
    ChangeNumberIndexerTest.java:
    In emptyDBTwoInitialDSs(), slightly modified the code to test current bug.
    In startCNIndexer(), added the initial ECL enabled domains as a parameter.

  • The changeNumber progression was blocked when the mediumConsistencyCSN was from a different baseDN than the new change to add to the changeNumber index DB.
    Fixed this problem by also storing the baseDN of the mediumConsistencyCSN in the ChangeNumberIndexer class.
    
    
    ChangeNumberIndexer.java:
    Renamed mediumConsistencyCSN to mediumConsistency and changed its type from CSN to Pair<DN, CSN>.
    In tryNotify(), removed the now useless baseDN parameter (replaced with mediumConsistency field).
    Improved comments.
    
    ChangeNumberIndexerTest.java:
    Renamed BASE_DN to BASE_DN1.
    Added BASE_DN2 and test emptyDBTwoInitialDSsDifferentDomains().
    In assertExternalChangelogContent(), did some renaming.
    
    SequentialDBCursor.java:

  • Small enhancements / cleanups.
    
    
    ChangeNumberIndexer.java:
    Always updated lastAliveCSNs as the very last thing because it is used to decide whether the medium consistency point can move forward.
    
    
    AddMsg.java:
    In toString(), renamed the incorrectly named "changeNumber" attribute to "csn" + merged V1 and V2 protocol paths.
    Extracted method encodeAttributes().
    javadoc cleanup.

  • Code cleanup in ECLServerHandler:
    The eligibleCSN was used when the ECLServerHandler was responsible for inserting replicaDB changes into the changeNumber index DB.
    To this end, the eligibleCSN was computed to provide a kind of "medium consistency point" ("kind of" because it was badly computed).
    After OPENDJ-1174, it is no longer ECLServerHandler's responsibility to inserting replicaDB changes into the changeNumber index DB, so the eligibleCSN is now useless and this commit removes it.
    
    In addition this commit enhances the toString() methods for a better readability.
    
    
    
    ECLServerHandler.java:
    Removed eligibleCSN field + refreshEligibleCSN().
    Renamed computeNextEligibleMessageForDomain() to computeNextAvailableMessage() + simplified code.
    In DomainContext, removed nextNonEligibleMsg field + removed isEligible(), debugInfo() and toString(CSN).
    In dumpState(), made the debug string more readable.
    In buildDomainContexts(), used DomainContext new ctor + extracted method newDomainContext() to build full DomainContext objects in one go + fixed a possible ConcurrentModificationException.
    In DomainContext, made some fields final + added a ctor + made toString() more readable.
    
    ReplicationServerDomain.java:
    Removed getEligibleCSN() and isServerConnected(), now unused.
    
    ReplicationServer.java:
    Removed getEligibleCSN(), now unused.
    
    ReplicationDomainDB.java, JEChangelogDB.java, ChangeNumberIndexer.java:
    Removed getDomainLastAliveCSNs(), now unused.
    
    ExternalChangeLogTest.java
    Consequence of the changes above.
