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
Add test that exhibits the issue when sending AMQP (non JMS) to Artemis that one mapping to Core JMS the destination is not resolving as the RoutingType can be missing.
Add fix.
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 test may fail if the live crashes too soon and the
message is directly sent to backup and the expected
blocking send will never happen.
To fix that a wait is added to ensure the message
is sent to the live (and intercepted) before
crashing the live.
This test fails occasionally because the queue's delivering thread
may interference with the consumer's iterator during consumers adding.
The result is that the first of the 2 consumers may get iterated
twice and therefore the messages received by the 2 consumers are
not even.
Tha change puts the message add after the consumer add so that
the delivering thread only kicks off after consumers are all added
and messages should be evenly distributed to both consumers.
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.
When the MQTT consumer client (cleanSession property set to true) reconnected, there are certain probabilities that these two bugs will occur.
This is because the MQTT consumer client thinks that its connection has been disconnected and triggers reconnection, but the MQTT connection is still alive at Artemis broker. This bug occurs when new and old connections occur while operating the same queue for unsafe behavior.
Multiple consumers using the same clientId in the cluster, the last consumer connection should close the previous consumer connection!

When broker's advisory is disabled (supportAdvisory=false) any
advisory consumer won't get created at broker and the advisory
consumer ID won't be stored.
Legacy openwire clients can have a reference of advisory consumer
regardless broker's settings and therefore when it closes the
advisory consumer the broker has no reference to it.
Therefore broker throws an exception like:
javax.jms.IllegalStateException: Cannot
remove a consumer that had not been registered
If the broker stores the consumer info (even it doesn't create
it) the exception can be avoided.
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.
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.
If a client sends a message to a multicast address and using a qpid-jms
client to receive the message from one of the queues using fully
qualified queue name will fail with following error message:
Address xxxx is not configured for queue support
[condition = amqp:illegal-state]
It should be able to receive the message without any error.
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
FakeQueue is not correctly setting the queue on its PageSubscription,
leading to fail the test due to NPEs when PageSubscription::getQueue
is being used.
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.
Previously the port was always random. This caused problems with
remote JMX connections that needed to overcome firewalls. As of
this patch it's possible to make the RMI port static and whitelist
it in the firewall settings.
With AMQP protocol when some messages are received in a transaction,
calling JMX QueueControl.listDeliveringMessages() returns empty list
before the transaction is committed.
Add test cases

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
This test can verify an issue fixed by the commit:
7a463f038a (ARTEMIS-2096)
The issue was reported later by users where messages
sent by amqp clients are having their body size
randomly being zero when received by multiple core
consumers.
This was also fixed on commit 48e0fc8f42 but that
was exclusively on 2.6.x branch.
Compaction is now reusing direct ByteBuffers on both
reading and writing with explicit and deterministic

Add/Extend test to ensure address-setting change made on live preserved on slave (after activation)
Add/Extend test to ensure security-setting change made on live preserved on backup (after activation)
Major refactoring of the AMQPMessage abstraction to resolve
some issue of message corruption still present in the code and
improve the API handling of message changes and re-encoding.
Improves handling of decoding of message sections limiting the
work to only the portions needed and ensuring the state data
is always updated with what has been done. Fixes issues of
corrupt state on copy of message or other changes in filters.
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.
The waits for expiration are set at the same value as the expiration
interval default to in the test support setup so on some runs there is a
race when waiting for the message to expire and the expiry task.
Once a re-encode of the message is done the buffer is not being marked
as valid and so subsequent checks on the buffer are all assuming the
message data is not valid and re-encoding over and over. This can lead
to poor performance in some cases and corrupted data in others.
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
Revert previous fix
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.
Ensure the broker looks at local receiver credit when checking for
credit top off threshold and then do a proper top off back to the high
water mark to sync with how client receivers manage their credit.
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
Update the Qpid JMS and Proton dependencies to lastest and sync Netty
with the 4.1.28.Final version used by Qpid JMS to avoid clash that
breaks a test. Adds override of new Proton-J WritableBuffer API that
allows it to use the Netty String encoder when needed instead of the
slower default version.
Update Qpid JMS to v0.36.0
Proton-J to v0.29.0
Netty to 4.1.28.Final
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.
An OpenWire client can use a compound destination name of the form
"a,b,c..." and consume from, or subscribe to, multiple destinations.
Such a compound destination only works for topics when the subscriber
is non-durable. Attempting to create a durable subscription on a
compound address will end up with an error.
The cause is when creating durable subs to multiple topics/addresses
the broker uses the same name to create internal queues, which
causes duplicate name conflict.
The deliver loop won't give up trying to deliver messages when
back-pressure kicks in (credits and/or TCP) if msg grouping is used and
there are many consumers registered: this change will allow the loop
to exit by instructing the logic that the group consumer is the only
consumer to check.
