Revision: 7199
http://bigdata.svn.sourceforge.net/bigdata/?rev=7199&view=rev
Author: thompsonbry
Date: 2013-06-14 16:28:32 +0000 (Fri, 14 Jun 2013)
Log Message:
-----------
This commit includes the test suite for this ticket:
AbstractHA3BackupTestCase: lifted out the logic to compute a snapshot time such that the snapshot can not run during the unit test.
AbstractHA3JournalServerTestCase: fixed documentation on copyFiles() (it does not copy an individual file) and exposed copyFile() (which does copy an individual file).
AbstractHAJournalServerTestCase: Added method to do "COUNT(*)" query (and task for running that query).
StressTestHA3JournalServer: Added a stress test test suite and put the DROP ALL + LOAD ACID stress test in there. We need to refactor other stress tests into this class as well.
TestAll: added references to the new tests.
TestHA3JournalServerWithHALogs: new test for [1].
TestHA3SnapshotPolicy2: logic to compute the "never run" snapshot time was lifted out of this class.
[1] http://sourceforge.net/apps/trac/bigdata/ticket/679 (HAJournalServer can not restart due to logically empty log file)

Revision: 7197
http://bigdata.svn.sourceforge.net/bigdata/?rev=7197&view=rev
Author: thompsonbry

Log Message:
-----------
I have modified HALogNexus to NOT add an empty HALog file on startup to the in-memory index iff it is the last HALog file in commit counter sequence for that service.
I have written a unit test for this behavior (TestHA3JournalServerWithHALogs.test_startABC_emptyLogFileDeletedOnRestartC()). I have verified that the test replicates the problem reported here and that the change to HALogNexus causes the test to run green.
I found and fixed a bug in the test harness where copyFiles() would not actually copy a single file (the fix was an update to the documentation). I also exposed the copyFile() method to subclasses.
Note: This commit does not include the test suite. I need to vet some other edits in the test suite before I can commit that code. However, this commit does fix the problem desribed for this ticket.
@see http://sourceforge.net/apps/trac/bigdata/ticket/679 (HAJournalServer can not restart due to logically empty log file)

+ * Test suite for {@link ClocksNotSynchronizedException}. The basic pattern of
+ * events is as follows:
+ *
+ * <pre>
+ * leader : t1 : timestamp before gather() messages are sent to followers.
+ * follower : t2 : timestamp taken when servicing gather() message and sent to leader with response.
+ * leader : t3 : timestamp taken on leader when barrier breaks.
+ * </pre>
+ *
+ * Of necessity, these events have a temporal order (t1 BEFORE t2; t2 BEFORE
+ * t3). However, there can be skew in the clocks such that the clock on the
+ * leader and the clock on the follower(s) are not synchronized. Some clock skew
+ * is allowed, but significant clock skew can cause a problem on failover.
+ * <p>
+ * The problem arises because the clocks are used to assign timestamps for
+ * commit points, and we index into the journal using those timestamps for
+ * historical reads (reading on the database as of some wall clock time).
+ * <p>
+ * {@link AbstractJournal#commitNow(long)} does ensure that time moves forward
+ * relative to the timestamp associated with the last commit point on the
+ * journal. However, if the skew is large, then this could require waiting for
+ * minutes, hours, or days before a new commit time could be assigned.
+ * <p>
+ * In order to avoid such long latency during failover, an error is reported
+ * proactively if a large clock skew is detected during the release time
+ * consensus protocol.
+ * <p>
+ * This test suite verifies the logic for detecting clock skew.

Log Message:
-----------
Refactored the HAReceiveService to be more robust to pipeline change events. This is to address an issue that Martyn has observed in HA CI runs where a CancellationException would be caught in QuorumPipelineImpl. The CancellationException is being interpreted as a normal termination, but what we want is the pipeline change event to trigger a retrySend(). This was observed for the changeDownstream event.
The change to the HAReceiveService is that we no longer interrupt the ReadTask (via the ReadFuture) in either changeDownstream() or changeUpstream(). Instead, we set a firstCause Throwable. If that firstCause is non-null, then it is thrown out of the ReadTask and the socketChannel is closed. This causes a well known exception (PipelineDownstreamChange or PipelineUpstreamChange) to be propagated back to retrySend(). We do not need to catch these exceptions explicitly since retrySend() will catch everything. However, the pipeline change now no longer causes a CancellationException to be propagated and thus retrySend() now will actually retry the replicated write.

Log Message:
-----------
Added freeMemory reporting to the banner (e.g., -Xmx). I looked around but was not able to identify a means to report the maximum direct memory for the JVM (-XX:MaxDirectMemorySize).
Added reporting of the memory pools for the counter sets (current and maximum usage by pool).
