This is a Large commit where I am refactoring largeMessage Body out of CoreMessage
which is now reused with AMQP.
I had also to fix Reference Counting to fix how Large Messages are Acked
And I also had to make sure Large Messages are transversing correctly when in cluster.
Issue: The BLOB manipulation is done using PostgreSQL internal classes starting from PGConnection.
This leads to ClasCastExceptions if the connection is wrapped in a pool or if the driver is in a different classloader (WildFly).
Fix: unwrap the connection and if the PostgreSQL classes are not directly available uses reflection to manipulate the BLOBs.
Jira: https://issues.apache.org/jira/browse/ARTEMIS-2626
AbstractJDBCDriver would hold an instance to AbstractJDBCDriver through an innner class,
that would hold an ActiveMQServerImpl.
That means Servers would be leaking for the entire duration of the testsuite when using JDBC.
* Upgrading versions
* Adding wildfly-common dependency as jboss-logmanager now depends on it
for simple common operations such as getting hostname or process id
* Updating bootclasspath with wildfly-common
There is no test for this as we don't have a way to embed/test Postgres.
It will need to be verified externally. However, given the exception the
fix looks solid.
DB2 metadata checks should erroneously report stale table existence on
not existing/just deleted table, making the subsequent warning logs
of failed SELECT COUNT useless and scaring: should be better to let
them lowered to INFO level
Compaction is now reusing direct ByteBuffers on both
reading and writing with explicit and deterministic
release to avoid high peak of native memory utilisation
after compaction.
Activate by enabling TRACE logging for:
org.apache.activemq.artemis.jdbc.store.drivers.AbstractJDBCDriver
This doesn't log *all* JDBC operations, just those that are used by the
JDBC store.
DB2 JDBC driver fail to retrieve metadata information
if table names are lower-cases: similarly to Oracle, better
force any table name to be upper-cases to avoid broker being
unable to restart when lower-cases table names are used
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.
