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 an example to demonstrate how to configure and use openssl
Moved/Added netty-tcnative dependency to artemis-distribution
Changed artemis-jms-client-all pom to exclude io.netty from relocation
so that the native openssl can be loaded
1. Add tests case to verify issue and fix, tests also tests for same behavior using CORE, OPENWIRE and AMQP JMS Clients.
2. Update Core Client to check for queue before creating, sharedQueue as per createQueue logic.
3. Update ServerSessionPacketHandler to handle packets from old clients to perform to implement the same fix server side for older clients.
4. Correct AMQP protocol so correct error code is returned on security exception so that amqp jms can correctly throw JMSsecurityException
5. Correct AMQP protocol to check for queue exists before create
6. Correct OpenWire protocol to check for address exists before create
If a client ack mode consumer receives a message and closes without
acking it, the redelivery of the message won't set the redelivery
flag (JMSRedelivered) because it doesn't increment the delivery count
when message is cancelled back to queue.
Replace guava Preconditions with artemis Preconditions
Replace guava Predicate with java Predicate
Replace guava Ordering with java Comparator
Replace guava Immutable, with ArrayList/Set and then wrap with unmodifiable
Configure a value of 128KB for AMQP max frame size by default to improve
overall performance and provide a limit on delivery size before chunking
begins.
Use new no copy variants for the delivery send and receive and make
use of the ReadableBuffer type that is now used to convery tranfer
payloads without a copy. Also set max outgoing frame size to match
the configured maxFrameSize for the AMQP protocol head to avoid the
case where an overly large frame can be written instead of chunking
a large message.
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)
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.
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
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
When creating a temp destination and auto-create-address set to false, the
broker throws an error and refuse to create it. This doesn't conform to
normal use-case (like amqp dynamic flag) where the temp destination should
be allowed even if the auto-create-address is false.
Make sure the correct buffer is used when decoding the stored Core
message that originated from the conversion of an AMQP message sent and
annotated as a JMS ObjectMessage which trips the large message boundary.
The cluster connection bridge has a TopologyListener and connects to a new node
each time it receives a nodeUp() event. It needs to put a check here to make
sure that the cluster bridge only connects to its target node and it's backups.
This issue shows up when you run LiveToLiveFailoverTest.testConsumerTransacted
test.
Also in this commit improvement of BackupSyncJournalTest so that it runs more
stable.
Add Test Case to stop and restart server after config reload and check state, this re-creates network health check issue where config changes are lost when network health check de-activates the server and then re-activates.
Add fix to update the held configuration thats used when initialisation steps during start are done.
connection
To prevent a socket from hanging open by a bad client the broker should
make sure to stop the transport if a connection attempt fails by an
OpenWire client
Revert #1875
This reverts commit 5ad45369ce.
The storage manager is broken now as the AddressManager change here is trying to insert a record on the journal before startup.
- LargeServerMessageImpl.finalize is eventually causing deadlocks
- CoreMessage needs to check properties before decoding
- PagingTest tweaks
- ServerLocatorImpl can deadlock eventually, avoiding a lock and using actors
- ActiveMQServerImpl.finalize is also evil and can cause deadlocks on the testsuite
- MqttClusterRemoteSubscribeTest needs to setup the Address now on the setup
The PageCountPendingImpl was increasing the encode size without using its full allocation.
This was causing issues on replication as the encode is also used to determine the size of the packets.
however the packets were not receive the full allocated data causing missing packets on the replication
and test failures.
This is fixing the issue
Adding new metrics for tracking message counts and sizes on a Queue.
This includes tracking metrics for pending, delivering and scheduled
messages. The paging store also tracks message size now.
Support exlusive consumer
Allow default address level settings for exclusive consumer
Allow queue level setting in broker.xml
Add the ability to set queue settings via Core JMS using address. Similar to ActiveMQ 5.X
Allow for Core JMS client to define exclusive consumer using address parameters
Add tests
Make sure that if a bridge disconnects and there is no record in the topology that it uses the original bridge connector to reconnect.
Originally the live broker that disconnected was left in the Topology, thie broke quorum voting as when th evote happened all brokers when asked though th etarget broker was still alive.
The fix for this was to remove the target live broker from the Topology. Since the bridge reconnect logic relied on this in a non HA environment to reconnect this stopped working.
The fix now uses the original target connector (or backup) to reconnect in the case where the broker was actually removed from the cluster.

When using the tool to import more than one large messages
from xml exported file, this utility class will create some
tmp files, each for one large message. However it only delete
one of the tmp files. All the rest of tmp files won't get
cleaned up.
HornetQClientProtocolManager is used to connect HornteQ servers.
During reconnect, it sends a CheckFailoverMessage packet to the
server as part of reconnection. This packet is not supported by
HornetQ server (existing release), so it will break the backward
compatibility.
Also fixed a failover issue where a hornetq NettyConnector's
ConnectorFactory is serialized to the clients who cannot
instantiate it because class not found exception.
ActiveMQTestBase has been enhanced to expose the Database storage configuration and by adding specific JDBC HA configuration properties.
JdbcLeaseLockTest and NettyFailoverTests have been changed in order to make use of the JDBC configuration provided by ActiveMQTestBase.
JdbcNodeManager has been made restartable to allow failover tests to reuse it after a failover.
Test consistency between live and backup, espacially on
a slow live.
The test use MessagePersister::encode to simulate slow IO condition.
After live started, we send 5 message with a delay(default 500ms),
then start backup, wait until replicated, then send more message
without delay. If all message sent successfully, the backup should
has the same messages as live. We assert the message number only.
Flag needs to be set when auto creating an address so that the address
can be removed later if auto delete is configured when creating a
subscription with MQTT
We provide a feature to mask passwords in the configuration files.
However, passwords in the bootstrap.xml (when the console is
secured with HTTPS) cannot be masked. This enhancement has
been opened to allow passwords in the bootstrap.xml to be masked
using the built-in masking feature provided by the broker.
Also the LDAPLoginModule configuration (in login.config) has a
connection password attribute that also needs this mask support.
In addition the ENC() syntax is supported for password masking
to replace the old 'mask-password' flag.
