- Avoid some Properties Decoding, checking if we need certain properties like scheduled delivery
- Avoid creating some unnecessary SimpleString instances
- Removed some intermediate ActiveMQBuffer allocation
- Removed some intermediate UnreleasableByteBuf allocation
Second attempt to fix the following compiler warning that is reported in Travis builds, this time using the correct cast type `Class<?>[]` which prevents temporary object allocation because of var-args handling:
```java
/home/travis/build/apache/activemq-artemis/artemis-core-client/src/main/java/org/apache/activemq/artemis/core/protocol/core/impl/wireformat/FederationStreamConnectMessage.java:151: warning: non-varargs call of varargs method with inexact argument type for last parameter;
return (FederationPolicy) Class.forName(clazz).getConstructor(null).newInstance();
cast to Class<?> for a varargs call
cast to Class<?>[] for a non-varargs call and to suppress this warning
```
This fixes the following compiler warning that is reported in Travis builds:
```
/home/travis/build/apache/activemq-artemis/artemis-core-client/src/main/java/org/apache/activemq/artemis/core/protocol/core/impl/wireformat/FederationStreamConnectMessage.java:151: warning: non-varargs call of varargs method with inexact argument type for last parameter;

When AMQPMessages are redistributed from one node to
another, the internal property of message is not
cleaned up and this causes a message to be routed
to a same queue more than once, causing duplicated
messages.
This commit introduces the ability to configure a downstream connection
for federation. This works by sending information to the remote broker
and that broker will parse the message and create a new upstream back
to the original broker.
A new feature to preserve messages sent to an address for queues that will be
created on the address in the future. This is essentially equivalent to the
"retroactive consumer" feature from 5.x. However, it's implemented in a way
that fits with the address model of Artemis.
The parameter failoverOnInitialConnection wouldn't seem to be used and
makes no sense any more, because the connectors are retried in a loop.
So someone can just add the backup in the initial connection.
When CoreMessage is doing copyHeadersAndProperties() it doesn't
make a full copy of its properties (a TypedProperties object).
It will cause problem when multiple threads/parties are modifying the
properties of the copied messages from the same message.
This will be particular bad if the message is a large message
where moveHeadersAndProperties is being used.
After a node is scaled down to a target node, the sf queue in the
target node is not deleted.
Normally this is fine because may be reused when the scaled down
node is back up.
However in cloud environment many drainer pods can be created and
then shutdown in order to drain the messages to a live node (pod).
Each drainer pod will have a different node-id. Over time the sf
queues in the target broker node grows and those sf queues are
no longer reused.
Although use can use management API/console to manually delete
them, it would be nice to have an option to automatically delete
those sf queue/address resources after scale down.
In this PR it added a boolean configuration parameter called
cleanup-sf-queue to scale down policy so that if the parameter
is "true" the broker will send a message to the
target broker signalling that the SF queue is no longer
needed and should be deleted.
If the parameter is not defined (default) or is "false"
the scale down won't remove the sf queue.
* 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
Add tests
Add fix - if timeout occurs on sending packet, calls same code that is invoked if timeout occurs on during ping aligning logic, and ensuring JMS connection exception listener gets invoked to inform the client logic to react.
Historically the broker has read the XML configuration file as a String,
substituted system properties, and then parsed that String into an XML
document. However, this method won't substitute system properties in the
files which are imported via xinclude. In order to substitue system
properties in xincluded files the substitution needs to be performed
after the file is parsed into an XML document. This commit implements
that change and refactors the XMLUtil class a bit to eliminate redundant
code, obsolete comments, etc.
Implement using the ActiveMQ5 JMSXGroupFirstForConsumer, property as default, but make it possible for future to make it configurable easily. (Not this PR)
Add test
In adding auto-delete queue level feature, its been noticed as some feature bits were added during hot fix branch, that there's api break with the 2.6.x hotfix branch.
This addresses that by fixing this in 2.7.x

add javadoc
Add ability to configure when creating auto created queues at the queue level
Add support for configuring message count check
Add test cases
Update docs
Support using group buckets on a queue for better local group scaling
Support disabling message groups on a queue
Support rebalancing groups when a consumer is added.
Push isDirectDeliver method from netty impl, to the Connection interface
Add support to InVMConnection for isDirectDeliver flag and ability to set via config, defaulting to false, to keep current default behavior.
Extend DirectDeliverTest to check InVM as well.
Any checkProperties();<usage of this.properties> pattern has been
replaced by an atomic checkProperties().<usage of returned properties>
to help both performance and consistency.
The cleanup is now performed into CoreTypedProperties both
for performance reasons (avoid lock/unlock many times)
and consistency, given that the operation is now atomic.
Add consumer priority support
Includes refactor of consumer iterating in QueueImpl to its own logical class, to be able to implement.
Add OpenWire JMS Test - taken from ActiveMQ5
Add Core JMS Test
Add AMQP Test
Add Docs
MULTICAST messages forwarded by a core bridge will not be routed to any
ANYCAST queues and vice-versa. Diverts have the ability to configure how
routing-type is treated. Core bridges now support this same kind of
functionality. By default the bridge does not alter the routing-type of
forwarded messages to maintain compatibility with existing behavior.
These improvements were also part of this task:
- Routing is now cached as much as possible.
- A new Runnable is avoided for each individual message,
since we use the Netty executor to perform delivery
https://issues.apache.org/jira/browse/ARTEMIS-2205
This helped decreasing a lot of pressure on GC by not creating
as many runnables for each write.
Besides this helps fixing some of the issues I would have had on refactoring AMQP
over flushing writes and other asynchronous issues.
Refactor ServerJMSMessage so it correctly transposes all JMSX headers.
Push common JMSX mappings for JMS to Message Interface mappings into MessageUtil to avoid duplication in ActiveMQMessage and ServerJMSMessage
Add test cases
Add GroupSequence to Message Interface
Implement Support closing/reset group in queue impl
Update Documentation (copy from activemq5)
Change/Fix OpenWireMessageConverter to use default of 0 if not set, for OpenWire as per documentation http://activemq.apache.org/activemq-message-properties.html
A synchronization block was missed during the AMQP refactoring.
This could impact use-cases involving diverts, cluster bridges, and
multiple concurrent consumers.
Implement custom LVQ Key and Non-Destructive in broker - protocol agnostic
Make feature configurable via broker.xml, core apis and activemqservercontrol
Add last-value-key test cases
Add non-destructive with lvq test cases
Add non-destructive with expiry-delay test cases
Update documents
Add new methods to support create, update with new attributes
Refactor to pass through queue-attributes in client side methods to reduce further method changes for adding new attributes in future and avoid methods with endless parameters. (note: in future this should prob be done server side too)
Update existing test cases and fake impls for new methods/attributes
Given that NettyConnector::createConnection isn't happening on the
channel's event loop, it could race with a channel close event, that
would clean the whole channel pipeline, leading to a NPE while
trying to use a configured channel handler of the pipeline.
Extend test case to reproduce problem of client created queues being incorrectly removed on simple reload of config.
Add a flag/field to the queues created by configuration/broker.xml so we can correctly filter only queues created/managed by config.
Update listConfiguredQueues to use the new queue flag
Add Tests
Add implementation inline with other queue updatable settings.
Enhance tests to ensure queue is not destroyed during config change and messages in queue already are preserved
First, QueueQuery should use address name for address settings
The name used for looking up address settings for a queue now uses the
address name if there is a local queue binding
Second, make sure sent credits to the server is the correct value
In some cases users who migrate from 1.x to 2.x may still want to keep
the legacy prefixes for their JMS destinations (i.e. "jms.queue.",
"jms.topic.", etc.). This commit adds a boolean on our ConnectionFactory
implementation so that it will use the old prefixes when invoking the
queue/topic creation methods on the Session implementation.
Fix checkstyle
Avoid duplicated logic
Ability to filter and group
Instantiate SimpleString property key once
Get property value via getObjectProprty to ensure all special mapped properties such as in AMQPMessage would return
Avoid a custom string to represent null, instead rely on Java's representation "null" by using Objects.toString to get the string value of the property value used to group by.
This commit adds support for tracking metrics for bridges for both
normal bridges and bridges that are part of a cluster. The two
statistics added in this commit are messages pending acknowledgement
and messages acknowledged but more can be added later.
In a live-backup scenario, if the live is restarted and shutdown too soon,
the client have a chance to fail on failover because it's internal topology
is inconsistent with the final status. The client keeps connecting to live
already shut down, never trying to connect to the backup.
It's a porting from HORNETQ-1572.

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
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.
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
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).
It includes:
- Message References: no longer uses boxed primitives and AtomicInteger
- Node: intrusive nodes no longer need a reference field holding itself
- RefCountMessage: no longer uses AtomicInteger, but AtomicIntegerFieldUpdater
It allows a user to customize the max allowed distance between system and DB time,
improving HA reliability by shutting down the broker when the misalignment
exceeds configured limit.
