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.
When auto-creation is off then older clients consuming messages from an
FQQN won't work. This commit fixes that problem and adds a compatibility
test to verify.
The changes from ARTEMIS-2189 mean that
o.a.a.a.c.s.i.ServerSessionImpl#deleteQueue
is no longer called from the same ServerSessionImpl instance that
created it which means that TempQueueCleanerUpper instances will leak.
To resolve the leak the client will only create a new session when
necessary instead of every time delete() is invoked.
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
LocalMonitor::under on PagingManagerImpl won't log anymore with a
warning message if the producers got unblocked and with info
if disk it getting freed
Performing direct deliveries of management messages could enter
a code path on QueueImpl::addTail with a NULL pageIterator: performing
a null check will avoid it to throw NPE.
The Audit log allows user to log some important actions,
such as ones performed via management APIs or clients,
like queue management, sending messages, etc.
The log tries to record who (the user if any) doing what
(like deleting a queue) with arguments (if any) and timestamps.
By default the audit log is disabled. Through configuration can
be easily turned on.

Direct and async deliveries lock QueueImpl::this and
ServerConsumerImpl::this in different order causing deadlock:
has been introduced a deliverLock to prevent both type of delivers
to concurrently happen, making irrelevant the lock ordering.
Added test reproducer and changed Queue::isDurableMessage usages into
Queue::isDurable to allow acks to hit the journal and being
correctly replicated across nodes.
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.
This is simply fixing the example under examples/features/standard/divert
Other tests are passing.
No additional tests are needed as the example on this case acts like a test.
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.
In Page.write(final PagedMessage message) if the page file is closed
it returns silently. The caller has no way to know that if the message
is paged to file or not. It should throw an exception so that the
caller can handle it correctly.
This causes random failure PagingTest#testExpireLargeMessageOnPaging().
The test shows that when the server stops it closes the page file.
In the mean time a message is expired to the expiry queue and if
the expiry queue is in paging mode, it goes to Page.write() and
returns without any error. The result is that the message is removed
from the original queue and not added to the expiry queue.
If we throw exception here it makes the expiration failed, the message
will not be removed from the orginal queue. Next time broker is started,
the message will be reloaded and expired again. no message lost.
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

There's a *slight* semantic change with the behavior of the queue query
and binding query to make them consistent with the address query, namely
that they will return the name of the queue and the name of the address
in every case and the returned names will be not use the FQQN syntax but
will be parsed to reflect their actual names in the broker.
There were two different but nearly identical implementations of
createQueue(). I consolidated these into a single method. There should
be no semantic differences.
When trying to get the bindings for an address the getBindingsForAddress
method will create a Bindings instance if there are no bindings for the
address. This is unnecessary in most circumstances so use the
lookupBindingsForAddress method instead and check for null.
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.
Large messages pendingRecordID is not accessed atomically, leading
to races that would lead to records that cannot been found on the
journal for deletion: it would lead to cause NPE that won't clean
the pending tasks on the current OperationContextImpl.
Adding a cleanup on error of those tasks and avoiding the race
to happen by adding proper synchronization will both enforce
correct clean up when something bad happen and avoid NPE.
In PagingManagerImpl#getPageStore() the operations on the map 'stores'
are not synchronzed and it's possible that more than one paging store is
created for one address.
PageSubscriptionImpl::ackTx is already performing a counter update
using the message persistent size: the size can be reused on
PagePosition::setPersistentSize, avoiding to query the page cache just
to compute it.
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
TransactionImpl::properties are often not used and could be
avoided to be allocated.
OperationContextImpl.TaskHolders instances are turned into static
classes to avoid refecencing back the context, making the life
easier for the GC.
OperationContexImpl volatile loads can be reduced to make the
code faster on the hot path.
When a receiving transaction is committed in a paging situation,
if a page happens to be completed and it will be deleted in a
transaction operation (PageCursorTx). The other tx operation
RefsOperation needs to access the page (in PageCache) to finish
its job. There is a chance that the PageCursorTx removes the
page before RefsOperation and it will cause the RefsOperation
failed to find a message in a page.
When a node tries to reconnects to another node in a scale down cluster,
the reconnect request gets denied by the other node and keeps retrying,
which causes tasks in the ordered executor accumulate and eventually OOM.
The fix is to change the ActiveMQPacketHandler#handleCheckForFailover
to allow reconnect if the scale down node is the node itself.
Not closing the InputStream makes this test flaky on Windows. The test
breaks because FileMoveManager::delete(java.io.File) Line 221 fails
to delete the file if it's still "owned" by the JVM process on Windows.
With AMQP protocol when some messages are received in a transaction,
calling JMX QueueControl.listDeliveringMessages() returns empty list
before the transaction is committed.

Keep original ConfigChangeTest
Apply new non-destructive fix.
Enhance tests to ensure messages in queues are not lost either on reload when running or when config changed on-restart (e.g. queue i not destroyed)
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.
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
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.
Seperate plugin interface by area, all extending a base interface.
Update code to check and call only plugins implementing specific interfaces.
Existing interface extends all the new interfaces for back compatibility or those who want simplicity and don't care about perf.
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.
Anonymous senders (those created without a target address) are not
blocked when max-disk-usage is reached. The cause is that when such
a sender is created on the broker, the broker doesn't check the
disk/memory usage and gives out the credit immediately.
Fix so that it only updates if not null, to avoid user being unset from existing api's,
This is similar to other values, that only change the value when not null.
This reverts commit c3fbd1b9e4.
Based on the discussion on the PR
https://github.com/apache/activemq-artemis/pull/2035 this shouldn't have
been merged. It's importing JMS-specific code into the core broker which
is something we've worked hard to eliminate in recent releases.

Authentication failures are currently only logged for CORE clients.
This change puts the logging in a central location which all protocols
use for authentication so that authentication failures are logged for
all protocols.
Calling close multiple times on ServerConsumer can result in multiple
notifications being routed around the cluster. This causes cluster
topology info to become skewed. Which affects a number of components
such as message redistribution, metrics and can eventually cause OOM
should multiple queues be redistributing at the same time.
After sending pages, the thread will hold the storage manager write lock
and send synchronization finished packet(use the parent thread pool) to
the backup node. At the same time, thread pool is full bcs they are
waiting for the storage manager read lock to write the page or journal,
leading to replication starting failure. Here we use io executor to send
replicate packet to fix thread pool starvation problem.
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.
When setting "default-max-consumers" in addressing setting in broker.xml
It has no effect on the "max-consumers" property on matching address queues.
Tests added as part of a previous commit
This closes#2107
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
When database persistence and no shared store option is being used,
Artemis is choosing to use InVMNodeManager, that is not providing
the same behaviour of FileLockNodeManager.
