OpenWireMessageConverter::toAMQMessage on bytes messages is lazy
allocating a write buffer with a default size of 1024 even when
it won't be used to write anything.
It avoid an useless allocation by reducing it to new byte[0].
It avoid using the system clock to perform the locks logic
by using the DBMS time.
It contains several improvements on the JDBC error handling
and an improved observability thanks to debug logs.
DB2 10.5 doesn't allow to append Blob data to an existing Blob,
producing unexpected errors: a custom DB2 sequential file
can perfom the append by using a customized UPDATE statement.
max-blob-size.db2 and create-file-table.db2 are changed to match the
2 GB max blob size limit allowed by DB2.
largeMessagesFactory::newBuffer could create a pooled direct ByteBuffer
that will not be released into the factory pool: using a heap ByteBuffer
will perform more internal copies, but will make it simpler to be garbage
collected.
QuorumFailOverTest.testQuorumVotingLiveNotDead fails
because the quorum vote takes longer time to finish than
the test expects to.
(The test used to pass until commit ARTEMIS-1763)
In order to avoid out of bounds reads to happen, the reading of the file
should avoid those readings to hit the DMBS and just return the expected
value.
The previous commit about this feature wasn't using the row count query
ResultSet.
The mechanics has been changed to allow the row count query
to fail, because DROP and CREATE aren't transactional and immediate
in most DBMS.
It includes a test that stress its mechanics if used with DBMS like
DB2 10.5 and Oracle 12c.
Additional checks and logs have been added to trace each steps.
JdbcNodeManager is configured to use the same network timeout
value of the journal and to validate all the timeout values
related to a correct HA behaviour.
The JDBC Connection leaks on:
- JDBCFileUtils::getDBFileDriver(DataSource, SQLProvider)
- SharedStoreBackupActivation.FailbackChecker::run on a failed awaitLiveStatus
