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.
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.
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
In some environments it is not allowed to create a schema
by the application itself. With this change the AbstractJDBCDriver
now tests if an existing table is empty and executes further
statements in the same way as if the table does not exist.
Replace GenericSQLProvider and other implementation by a single
PropertySQLProvider that uses properties to define SQL queries.
SQL queries are loaded from the journal-sql.properties file.
Queries specific to a DB dialect can be specified by adding a suffix to
the key of the generic property.
For example, the generic property to create a file Table is:
create-file-table = CREATE TABLE %s (ID BIGINT AUTO_INCREMENT, ...)
This property can be customized for Derby by using the
create-file-table.derby property:
create-file-table.derby=CREATE TABLE %s (ID BIGINT NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1),...

In order to make the JDBC Node Manager more resilient has been implemented:
- recovering with fixed number of retries during the NodeId setup + unrecoverable failure otherwise
- unrecoverable fail on exceptions while renewing a lease lock
In addition, in different parts of these critical processes are added more log informations to help diagnose.
The JDBCSequentialFile blocks on the writeLock when opening. There is
no need to block here, in fact it may cause issues when opening and
syncing concurrently. Instead an AtomicBoolean is enough to prevent the
file from being reloaded.
Multiplication operations where the operands have type `int` but the
result is cast to `long` may lead to overflow.
Fixes two instances of this problem, by ensuring the operands are cast
to `long` during multiplication.
This resolves the "Result of integer multiplication cast to long"
alerts at https://lgtm.com/projects/g/apache/activemq-artemis/alerts.
with this we could send and receive message in their raw format,
without requiring conversions to Core.
- MessageImpl and ServerMessage are removed as part of this
- AMQPMessage and CoreMessage will have the specialized message format for each protocol
- The protocol manager is now responsible to send the message
- The message will provide an encoder for journal and paging
Removes cyclic dependencies between classes and packages in the artemis-jdbc-store projetct by moving classes and methods to other locations and reducing the visibility of classes, fields and methods. Solving cyclic dependencies is important to keep the codebase maintainable. Scenarios where "everything uses everything" should be avoided.
* add DataSource property to DatabaseStorageConfiguration to be able to
communicate with the data store using this DataSource instance instead
of relying on the creation the SQL connnection using the JDBC connection
URL/driver class name tuple.
* add SQLProvider.Factory property to DatabaseStorageConfiguration to
externalize the choice of the SQLProvider instead of relying on
hard-coded choices. If the property is null, the current behaviour will
be used (determing the SQLProvider based on the driver class name)
* bindingsJournal and messageJournal are already started in the start()
method. Remove redundant calls that were creating unused JDBC
connections that are never closed.
