These tests are using an asynchronous feature. the check on Log has to use the Wait.assertEquals
I had to make a few changes to the methods to allow the use of Wait
Generate MQTT message IDs from full allowed range of 1-65535 and skip
currently used values. Do not use atomic integer for current ID, because
all accesses and modifications are performed in synchronized context.
When Queue consumers attach with filters use those instead of the Queue
filter to filter the messages that are federated to avoid stranding of
messages on the local broker. This will result in multiple federation
consumers if the various attached local consumers all use different
filters but does keep unwanted messages on the remote so that consumers
there can consume those.
Under some scenarios federation demand tracking is losing track of total demand
for a federated resource leading to teardown of federated links before all local
demand has been removed from the resource. This occurs most often if the attempts
to establish a federation link are refused because the resource hasn't yet been
created and an eventual attach succeeds, but can also occur in combination with
a plugin blocking or not blocking federation link creation in some cases.
Large message support was added to
o.a.a.a.c.s.f.FederatedQueueConsumerImpl#onMessage via cf85d35 for
ARTEMIS-3308. The problem with that change is that when onMessage
returns o.a.a.a.c.c.i.ClientConsumerImpl#callOnMessage will eventually
call o.a.a.a.c.c.i.ClientLargeMessageImpl#discardBody which eventually
ends up in o.a.a.a.c.c.i.LargeMessageControllerImpl#popPacket waiting 30
seconds (i.e. the default readTimeout) for more packets to arrive (which
never do). This happens because the FederatedQueueConsumer short-cuts
the "normal" process by using LargeMessageControllerImpl#take.
This commit fixes that by tracking the number of bytes "taken" and then
looking at that value later when discarding the body effectively
skipping the 30 second wait.
When an AMQP federation instance attempts to federate an address or queue
it can fail if the remote address or queue is not present or cannot be
created based on broker policy. A federation link can also closed if the
federated resource is removed from the remote broker by management etc.
In those cases the remote broker should note the resources that were
targets of federation and send alerts to the source federation broker to
notify it that these resources become available for federation and the
source should attempt again to create federation links if demand still
exists. This allows an AMQP federation instance to heal itself based on
updates from the remote.
No problems reported on this test.
I needed to validate rather if messages were being distributed correctly when either SNF or the final address itself was paged. Rather than throw away the test I decided to keep the validation here.
I had to remove the indirect dependency between the maven plugin and jline
to avoid the maven plugin to parse some classes in jline that require experimental features on the JDK
even when they are not in use.
Currently when an MQTT topic filter contains characters from the
configured wildcard syntax the conversion to/from this syntax breaks.
For example, when using the default wildcard syntax if an MQTT topic
filter contains a . the conversion from the MQTT wildcard syntax to the
core wildcard syntax and back will result in the `.` being replaced with
a `/.`.
This commit fixes that plus a few other things...
- Implements proper conversions to/from one WildcardConfiguration to
another.
- Refactors the MQTT code which invokes these conversion methods. This
includes simplifying a lot of test code.
- Adds lots of tests for everything.
- Clarifies some variable naming to better distinguish between core and
MQTT.
- Move ActiveMQTestBase to artemis-test-support.
- Add reduced parent for current artemis-server tests.
- Add a simpler test case parent class unit tests can use.
- Convert some existing checks into a rule for reuse.
- Move various rules/utils to artemis[-unit]-test-support module from where they can be used instead of from artemis-server.
If both scale-down and cluster-connection are using the same JGroups
discovery-group then when the cluster-connection stops it will close the
underlying org.jgroups.JChannel and when the scale-down process tries to
use it to find a server it will fail.
This commit ensures that the JGroupsBroadcastEndpoint implementation of
BroadcastEndpoint#openClient initializes the channel if it has been
closed.

If the broker is embedded into a Jakarta environment then the existing
artemis-openwire-protocol module won't work because it uses javax
classes.
This commit adds a new Jakarta-specific module that can be used to
support OpenWire clients in Jakarta environments (e.g. Spring Boot 3).
Users will simply need to include this version on their classpath to
enable support.
Allows the configuration of AMQP Federation broker connections to be updated and
reloaded. This allows for update, add or remove of AMQP federation broker connections
as well as the basic AMQP sender and receiver broker connections. It checks for and
ignores changes in AMQP broker connections that are performing Mirroring as that
would lead to issues that can break mirroring.
When initially developed the expectation was that no more producers would keep connecting but in a scenario like this
the consumers could actually give up and things will just accumulate on the server.
We should cleanup these upon disconnect.
Mirror acks should be performed atomically with the storage of the source ACK. Both the send of the ack and the recording of the ack should be part of the same transaction (in case of transactional).
We are also adding support on transactions for an afterWired callback for the proper plug of OperationContext sync.
- Async commit
* async here meaning the recording of the commit record is not doing a sync on the storage.
This is useful for internal operations where we don't need an immediate sync on the journal storage.
- Wired notification
* I need finer control on a afterWired (to the storage) and before the completions, so I can plug the sync context on mirror right before the commit is called.
Many MQTT tests are run twice - once using TCP and once using
WebSockets. This is essentially a big waste of time since once the
connection is established to the broker the tests are identical. The
tests should be refactored to run just once and then there can be a
small number of tests specifically for WebSockets.
This should knock several minutes off the test-suite.
This commit does the following:
- Replaces non-inclusive terms (e.g. master, slave, etc.) in the
source, docs, & configuration.
- Supports previous configuration elements, but logs when old elements
are used.
- Provides migration documentation.
- Updates XSD with new config elements and simplifies by combining some
overlapping complexTypes.
- Removes ambiguous "live" language that's used with regard to high
availability.
- Standardizes use of "primary," "backup," "active," & "passive" as
nomenclature to describe both configuration & runtime state for high
availability.

ShutdownOnCriticalIOErrorMoveNextTest was actually my "inspiration" to have created the isolated tests module in the first place, so it would be reasonable to move it there as well.
the issue comes down to the test simulating a server failure where the server would go down abruptly causing the VM to drop / exit. In this test the nature of failure is leaving a partial shutdown where server executors are still hanging around causing a cascade leak of server pools still running.
So it is completely expected to have these threads "leaking". Hence this test should be moved into the isolated-tests.
there is no semantic / server change as part of this task. It's just moving a test to a better place.
As I worked through implementing a more generic JSON marshaller, I tried using reflection through BeanUtils and other ways
however the endresult was always worse as there were a few caveats that were not as easy to accomplish.
For that reason I went to a declarative appraoch where I define a meta-data object on AddressSettings and AddressSettingsInfo and
reuse the metadata in a few other places.
Starting with 2.28.0, the broker doesn't translate the character `/` to
the configured wildcard delimiter (i.e. `.` by default) when creating
subscription queues for MQTT clients.
This commit fixes that regression and restores the proper translation.
Allow for core messages to be tunneled over broker connection links used
for AMQP Federation and for broker mirroring. This eliminates the need to
convert from Core to AMQP and from loading core large messages fully into
memory for that conversion.
I was not able to reproduce the actual issue here, but I heavily used this test during debugging.
This will not serve as a reproducer to the Ghost consumer issue, but this is a valid test.
The system property `artemis.extra.libs` is a comma separated list of
directories that contains jar files, i.e.
```
-Dartemis.extra.libs=/usr/local/share/java/lib1,/usr/local/share/java/lib2
```
The environment variable `ARTEMIS_EXTRA_LIBS` is a comma separated list of
directories that contains jar files and is ignored if the system property
`artemis.extra.libs` is defined, i.e.
```
export ARTEMIS_EXTRA_LIBS=/usr/local/share/java/lib1,/usr/local/share/java/lib2
```
When big messages are produced if a consumer receives an expired message, the credits are not updated, so if the consumer is too slow and an expiry delay has been set, we can end up with a situation where there are no more credits which prevents the consumer from receiving any more messages.
In case the bindings "news.#" and "news.europe.#" are registered, only the first one matches with the address "news.europe" while both are supposed to match. Those changes are meant to get rid of this limitation.
Durable subscrption state is part of the MQTT specification which has
not been supported until now. This functionality is implemented via an
internal last-value queue. When an MQTT client creates, updates, or
adds a subscription a message using the client-ID as the last-value is
sent to the internal queue. When the broker restarts this data is read
from the queue and populates the in-memory MQTT data-structures.
Therefore subscribers can reconnect and resume their session's
subscriptions without have to manually resubscribe.
MQTT state is now managed centrally per-broker rather than in the
MQTTProtocolManager since there is one instance of MQTTProtocolManager
for each acceptor allowing MQTT connections. Managing state per acceptor
would allow odd behavior with clients connecting to different acceptors
with the same client ID.
The subscriptions are serialized as raw bytes with a "version" byte for
potential future use, but I intentionally avoided adding complex
scaffolding to support multiple versions. We can add that complexity
later if necessary.
Some tests needed to be changed since instantiating an MQTT protocol
manager now creates an internal queue. A handful of tests assume that no
queues will exist other than the ones they create themselves. I updated
the main test super-class so that an MQTT protocol manager is not
automatically instantiated when configuring a broker for in-vm support.
The exception thrown by serverLocator.connect() should be all you need on such case
and the caller should then be responsible for taking appropriate action.
Only report finding matching log message if all requested entries are present in it, not just the last one provided.
Also fix the updated AssertionLoggerHandler usage within AddressFullLoggingTest, ensure it is active across the full period expected messages can happen and doesnt miss early ones.
The test cannot work on Windows unless I can make the `upgrade` CLI command
respect my choice to upgrade a Linux distribution. This commit therefore adds
a new `--linux` option for the `upgrade` command, and leverages it in the
`upgrade-linux` smoke test.
* The `--cygwin` option has been preserved for backwards compatibility.
* The `IS_CYGWIN` attribute has been renamed to `IS_NIX` to reflect the change.
* The OS "recognition" method (in `InstallAbstract::run`) has been updated to
reflect the need for enforcing *nix behavior, which is now the default if all
other methods fail.
This commit introduces support for configuring a specific Duplicate ID cache size per address in the Artemis server. Previously, there was only a global setting for the ID cache size, but now each address can have its own cache size.
The changes include the addition of a new configuration property id-cache-size in the Artemis server configuration file. This property can now be specified under each address setting in the configuration file, and its value will determine the Duplicate ID cache size for that particular address. If the id-cache-size property is not specified for an address, it will use the global setting.
The test cases have been updated to cover this new functionality, and integration test have been added to verify that address-specific cache sizes work as expected.
Documentation has been added to address-settings.adoc, configuration-index.adoc and duplicate-detection.adoc
ARTEMIS-4375 Implement artemis shell using JLine3 integrated with auto-completion from picocli
This commit involves two JIRAs. One is adding PicoCLI and the next is Using JLine3 and implement a shell.
I have tried to keep these commits separate but these changes became interdependent hence the two JIRAs are squashed in this commit.
The test is now setting the mirror to sync
it will block until the first subscription is consumed, kill the servers and restart them
check all the counters
and then start another 4 consumers and at the end check all the counters.
Mirror is now sync making the test more useful and challenging.
This commit contains the following changes:
- eliminate used, undeclared dependencies
- eliminate unused, declared dependencies
- fix scope for test dependencies
- eliminate org.hamcrest completely as its use involved deprecated code
as well as dependencies from multiple versions
In rare cases a store operation could silently fails or starves, blocking the
related server session and all delivering messages. Those server sessions can
be closed adding a management method that cleans their operation context
before closing them.
If the Security Manager is using Netty, and in particular the same Netty connection,
you could run into a deadlock / starvation.
This is particularly true in the Wildfly case where they reuse the same connection for everything via XNIO.
When resource audit logging is enabled STOMP is completely inoperable
due to an NPE during the protocol handshake. Unfortunately the failure
is completely silent. There are no logs to indicate a problem.
This commit fixes this problem via the following changes:
- Mitigate the original NPE via a check for null
- Move the logic necessary to set the "protocol connection" on the
"transport connection" to a class shared by all implementations.
- Add exception handling to log failures like this in the future.
- Add tests to ensure the audit logging is correct.
Improve the CORE client failover connecting to other live servers when all
reconnect attempts fails, i.e. in a cluster composed of 2 live servers,
when the server to which the CORE client is connected goes down the CORE
client should reconnect its sessions to the other liver broker.

I am also allowing optionally testing with mysql.
The CLI maven plugin is creating a server and downloading the JDBC jar directly into the ./server/lib folder.
Notice this is a test dependency only and it will be used only if mysql is set to true.
Some scrapers, e.g. prometheus, add an "instance" tag. This value may not be the same as
the broker name, which results in these metrics becoming more difficult to match up with
the corresponding broker.

The broker process fails to exit if an error is encountered starting the NodeManager. The issue is resolved by converting the critical analyzer thread to a daemon thread. As added protection, the thread is manually stopped when this error is encountered.
Many of the tabs on the web console show up even though the user doesn't
have permission to execute the command corresponding to the tab. For
example the "Connections" tab shows up even though the user can't
execute the `listConnections` management operation.
When skipping the authentication cache details for the original
exception are not logged.
This commit ensures these details are logged and adopts the
ExceptionUtils class from Apache Commons Lang in lieu of the previous
custom implementation.
When sending, for example, to a predefined anycast address and queue
from a multicast (JMS topic) producer, the routed count on the address
is incremented, but the message count on the matching queue is not. No
indication is given at the client end that the messages failed to get
routed - the messages are just silently dropped.
Fixing this problem requires a slight semantic change. The broker is now
more strict in what it allows specifically with regards to
auto-creation. If, for example, a JMS application attempts to send a
message to a topic and the corresponding multicast address doesn't exist
already or the broker cannot automatically create it or update it then
sending the message will fail.
Also, part of this commit moves a chunk of auto-create logic into
ServerSession and adds an enum for auto-create results. Aside from
helping fix this specific issue this can serve as a foundation for
de-duplicating the auto-create logic spread across many of the protocol
implementations.
testSimpleResume is intermittently failing.
This test is forcing another page, while cleanup is happening on the background.
ForceAnotherPage may not put the address back into paging if this happened right after the cleanup call.
To fix the test, we should call startPaging after forceAnotherPage is called.
- activemq.notifications are being transferred to the target node, unless an ignore is setup
- topics are being duplicated after redistribution
- topics sends are being duplicated when a 2 node cluster mirrors to another 2 node cluster, and both nodes are mirrored.
- interrupted message breaking reference counting
After the server writing to the client is interrupted in AMQP, the reference counting was broken what would require the server restarted
in order to cleanup the files of any interrupted sends.
- Removed consumer during large message delivery damaging large messages
If the consumer failed to deliver messages for any reason, the message on the queue would be duplicated. what would wipe out the body of the message
and other journal errors would happen because of this.
extra debug capabilities added into RefCountMessage as part of ARTEMIS-4206 in order to identify these issues
This test is boundless adding data into the journal when there are no syncs.
That's creating 600MIB worth of data on our CIs, and this tests was not meant to be acting like a soak test.
I'm limitting the load the test can generate with a TokenBucketLimiterImpl now.
MQTT5Test::testMaxMessageSize is spiking the memory on the integration testsuite all the way up to 1.5G
what makes this test more like a soak test.
The test is now converted to use a real server like other Soak Tests.
This fix will delay the message.copy to the redistributor itself.
Meaning no copy would be performed if the redistribution itself failed.
No need to remove a copy any longer
The federated queue consumer has to generate a new id for the messages
received from the upstream broker because they have an id generated by
the store manager of the upstream broker.

- redistribute received the handle call, it then copies the message
- the routing table changes
- the message is left behind
With the new version of the server these messages will be removed. But we should remove these right away
Basically I started the testsuite and attached check leak with "java -jar check-leak.jar --pid <pid> --report testsuite-report --sleep 1000" and saw the allocations of this were pretty high.
This fix is scanning journal and paging for existing large messages. We will remove any large messages that do not have a corresponding record in journals or paging.
This failure was because of a noise from the test itself. as the test is creating a producer, and it's measuring for a producer from the test.
it makes no sense to fix it for OverCore.. we just ignore it on UsingCore
Fixes the CompareUpgradeTest by removing this unimportant difference from a fresh broker instances jolokia-access.xml file, given that we dont actually update jolokia-access.xml currently during upgrade.
Tweaks or unwinds earlier changes in aae65fd527 and 3e7cb24381
There are certain use-cases where addresses will be auto-created and
never have a direct binding created on them. Because of this they will
never be auto-deleted. If a large number of these addresses build up
they will consume a problematic amount of heap space.
One specific example of this use-case is an MQTT subscriber with a
wild-card subscription and a large number of MQTT producers sending one
or two messages a large number of different MQTT topics covered by the
wild-card. Since no bindings are ever created on any of these individual
addresses (e.g. from a subscription queue) they will never be
auto-deleted, but they will eventually consume a large amount of heap.
The only way to deal with these addresses is to manually delete them.
There are also situations where queues may be created and never have
any messages sent to them or never have a consumer connect. These
queues will never be auto-deleted so they must be deleted manually.
This commit adds the ability to configure the broker to skip the usage
check so that these kinds of addresses and queues can be deleted
automatically.
there are two leaks here:
* QueueImpl::delivery might create a new iterator if a delivery happens right after a consumer was removed, and that iterator might belog to a consumer that was already closed
as a result of that, the iterator may leak messages and hold references until a reboot is done. I have seen scenarios where messages would not be dleivered because of this.
* ProtonTransaction holding references: the last transaction might hold messages in the memory longer than expected. In tests I have performed the messages were accumulating in memory. and I cleared it here.
The issue identified with AMQP was under Transaction usage, and while opening and closing sessions.
It seems the leak would be released once the connection is closed.
We added a new testsuite under ./tests/leak-tests To fix and validate these issues
