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
Expose method to return current mappings of groups to consumers
Expose methods to reset (remove) specific group mapping from groupID to Consumer
Expose methods to reset (remove) all group mappings
messageAcknowledged plugin callback methods
Knowing the consumer that expired or acked a message (if available) is
useful and right now a message reference only contains a consumer id
which by itself is not unique so the actual consumer needs to be passed
When finding out if a connector belong to a target node it compares
the whole parameter map which is not necessary. Also in understanding
the connector the best place is to delegate it to the corresponding
remoting connection who understands it. (e.g. INVMConnection knows
whether the connector belongs to a target node by checking it's
serverID only. The netty ones only need to match host and port, and
understanding that localhost and 127.0.0.1 are same thing).
The queue metrics were being decremented improperly because on iteration
over the cancelled scheduled messages because the flag for fromMessageReferences was not
set to false. Setting the flag to false skips over the metrics update
which is what we want as the scheduled messages were never added to the
message references in the first place so the metrics don't need updating
