* 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
Any failure to deploy an address or queue will short-circuit the broker
initialization process preventing any other addresses or queues from
being deployed as well as other critical resources like acceptors, etc.
The ServerSessionPacketHandler has a close() callback handler which will
delete any pending large messages. However, there is a race where a
large message can be routed, then the close delete the associated large
message resulting in data loss.
Quorum voting is used by both the live and the backup to decide what to do if a replication connection is disconnected.
Basically, the server will request each live server in the cluster to vote as to whether it thinks the server it is replicating to or from is still alive.
You can also configure the time for which the quorum manager will wait for the quorum vote response.
Currently, the value is hardcoded as 30 sec. We should change this 30-second wait to be configurable.
- Added Wait.assert methods, what would make it easier to assert on future conditions
- Moved Wait to artemis-junit, we are now using that module on the testsuite
The Critical analyzer is supposed to catch Deadlocks, and such
can only be resolved by killing the VM.
This test is using shutdown as it would be a bit more complex to
handle Byteman to then halt the VM. This will validate the
CriticalAnalyzer is capturing the event, and in such it would halt the VM.
When calling a consumer to receive message with a timeout
(receive(long timeout), if the consumer's buffer is empty, it sends
a 'forced delivery' the waiting forever, expecting the server to
send back a 'forced delivery" message if the queue is empty.
If the connection is disconnected as the arrived 'forced
delivery' message is corrupted, this 'forced delivery' message
never gets to consumer. After the session is reconnected,
the consumer never knows that and stays waiting.
To fix that we can send a 'forced delivery' to server right
after the session is reconnected.
The MAPPED journal refactoring include:
- simplified lifecycle and logic (eg fixed file size with single mmap memory region)
- supports for the TimedBuffer to coalesce msyncs (via Decorator pattern)
- TLAB pooling of direct ByteBuffer like the NIO journal
- remove of old benchmarks and benchmark dependencies
This method name would clash with ServiceComponent
As the real meaning here on this method is just to failover
So I've renamed the method to avoid the clash with my next commit
(I've done this on a separate commit as you may need to redo this
commit from scratch again in other branches instead of lots of clashes on cherry-pick)
When a large message is being diverted, a new copy of the original
message is created and replicated (if there is a backup) to the backup.
In LargeServerMessageImpl.copy(long) it reuse a byte array to copy
message body. It is possible that one block of date is read into
the byte array before the previous read has been replicated,
causing the replicated bytes to corrupt.
If we make a copy of the byte array before replication, the corruption
of data will be avoided.
