Implements a new feature for the broker whereby it may automatically create and
delete JMS topics which are not explicitly defined through the management API
or file-based configuration. A JMS topic is created in response to a sent
message or connected subscriber. The topic may subsequently be deleted when it
no longer has any subscribers. Auto-creation and auto-deletion can both be
turned on/off via address-setting.
The previous fix was breaking compatibility with older servers.
We need to check the default address if an exception happened during the send (due to flow control or blocker)
ActiveMQConnection implements FailoverEventListener which executes client's
FailoverEventListeners in separated threads in background. The old implementation
does not guarantee ordering of their executions. The commit improves the
implementation to guarantee it.
https://issues.apache.org/jira/browse/ARTEMIS-524
I am keeping all the debug ad tracing I added during the debug of this issue,
for that reason this commit may look longer than expected
The fix will be highlited by the tests added on org.apache.activemq.artemis.tests.integration.client.PagingTest
1. Changed public fields in ActiveMQClient to private and added getters.
Exposing fields for thread pool sized allow to modify them in undesired ways.
I made these fields private and added corresponding getter methods.
In addition, I renamed the field 'globalThreadMaxPoolSize'
to 'globalThreadPoolSize' to be more consistent with the
'globalScheduledThreadPoolSize' field name.
I also adapted some tests to always call clearThreadPools after
the thread pool size configuration has been changed.
2. Protect against injecting null as thread pools
ActiveMQClient.injectPools allowed null as injected thread pools.
The effect was that internal threads pools were created,
but not shutdown correctly.
TheJMSVendor protocol convertor class was not creating the destinations so any destination calls, setTo and setJMSReplyTo, were ignored. Ive added a server side destination class to bypass the naming checks we have on the client and this now sets everything correctly

This will have some extra refactoring on the protocol head, transferring responsibility to the broker classes in a lot of cases
and removing some duplicated code
This was a team effort from Clebert Suconic and Howard Gao
This patch fixes a number of bugs with the JDBC Journal implementation.
Mainly around how it was handling transactions. The XA transactions
tests are now enabled to test both the File and Database store.
This feature required a bit of refactoring to the plugin interface itself as
well as a restriction on the configuration so that either only one plugin could
be specified or an ulimited number of security-setting matches. This was done
to prevent messy situations where a plugin could update settings from the XML
or even another plugin if there were overlapping matches.
DelegatingSession class wraps ClientSessionImpl and attempts to close
session should it not be closed by the user. It does this by
implementing finalize. However, the order in which finalize runs can be
difficult to predict as compilers, and JIT compilers are able to
optimize early.
The current DelegatingSession was causing problems of finalize getting
called early (before consumers, producers were finished with the
session). This was causing tests to fail on the IBM JDK (which
optimizes early). The same happens on OpenJDK if the GC is forced.
Its now possible to also add the broker name to jmx tree avoiding clashes when multiple brokers are in a single vm. This is now the default but the old way can be used with some configuration
https://issues.apache.org/jira/browse/ARTEMIS-311
The old property-file based security manager shouldn't be used anymore. Instead
use the JAAS InVMLoginModule for in-vm tests, embedded use-cases, etc. and use
the other JAAS login modules for normal server use-cases.
The failback process needs to be deterministic rather than relying on various
incarnations of Thread.sleep() at crucial points. Important aspects of this
change include:
1) Make the initial replication synchronization process block at the very
last step and wait for a response from the replica to ensure the replica has
as the necessary data. This is a critical piece of knowledge during the
failback process because it allows the soon-to-become-backup server to know
for sure when it can shut itself down and allow the soon-to-become-live
server to take over. Also, introduce a new configuration element called
"initial-replication-sync-timeout" to conrol how long this blocking will occur.
2) Set the state of the server as 'LIVE' only after the server is fully
started. This is necessary because once the soon-to-be-backup server shuts
down it needs to know that the soon-to-be-live server has started fully before
it restarts itself as the new backup. If the soon-to-be-backup server restarts
before the soon-to-be-live is fully started then it won't actually become a
backup server but instead will become a live server which will break the
failback process.
3) Wait to receive the announcement of a backup server before failing-back.
Netty 4.x uses pooled buffers. These buffers can run out of memory when
transferring large amounts of data over connection. This was causing an
OutOfMemory exception to be thrown on the CoreBridge when tranferring
large messages. Netty provides a callback handler to notify listeners
when a Connection is writable. This patch adds the ability to register
connection writable listeners to the Netty connection and registers the
relevant callback from the Bridge to avoid writing when the buffers are
full.
It is possible for the closure of one resource to potentially impact
another since they are now sharing the same ServerLocator instance.
Keep track of references to avoid this.
In one situation I have seen a failrue on ProducerFlowControl to break everything else from here
This change will both avoid the failure and change the report of leaked threads so we can find them easily on the system.out when it happens (for future debugging)
Inbound sessions are always created from the same ActiveMQConnectionFactory
which means the load-balancing policy is applied to them in the expected
manner. However, outbound sessions are created from independent, unique
ActiveMQConnectionFactory instances which means that the load-balancing
doesn't follow the expected pattern.
This commit changes this behavior by caching each unique
ActiveMQConnectionFactory instance and using it for both inbound and outbound
sessions potentially. This ensures the sessions are load-balanced as
expected.
this is just calling Idea format on all the files using the new style
I am separating manual changes from automatic changes in case I have to repeat the manual changes again

On this pass I'm just converting the native layer to a simpler one.
It wasn't very easy to change the alignment at the current framework,
so I did some refactoring simplifying the native layer
The volume of the nubmer of changes here is because:
- The API is changed, we now don't close the libaio queue between files
- The native layer won't use malloc as much as it used to, saving some CPU and memory defragmentation
- I organized the code around nio and libaio
https://issues.apache.org/jira/browse/ARTEMIS-138
The list method should return an empty list in case of non existent folders,
So this would unveil whatever is the cause for non existent folders at the next level where it's happening
https://issues.apache.org/jira/browse/ARTEMIS-136
From what I researched from implementers of XA TM if you throw ERR over communication errors the transaction manager will create
an heuristic transaction to be manually dealt with.
Other XA Implementations (such as Oracle JDBC) are return FAIL over communication failures during any XA operation.

We had a few reported small issues on the codebase from the recent introduced google error prone.
This should eliminate any issues, and I am making sure these won't happen again
If standalone backup server with shared has defined scale-down policy
but it's disabled then backup does not activate. Problem is that
server is checking only whether scale down is defined but if it's
enabled. This causes that server.stop() is called and backup does
not activate.
Lots of work on the test-suite in this commit including:
- Rename ServiceTestBase to ActiveMQTestBase
- Make AddressSettings fluent
- Remove unnecessary tearDown() implementations
- Use ActiveMQTestBase.create*Locator() instead of
ActiveMQClient.createServerLocator*(..)
- Use fluent ServerLocator methods
- Make sure all ActiveMQServers.newActiveMQServer invocations
are surrounded with addServer() where appropriate
- Create a few example tests to be references from hacking-guide
- Update hacking-guide with more info on writing tests
- Refactor config creation methods in ActiveMQTestBase
This has bothered me for awhile, but writing the hacking guide has
given me an opportunity to refactor some of our test-suite to be
simpler, more consistent, and easier to understand. This is
important if we want users to provide well-written tests. Our
test-suite is an important part of the code-base and it should be
easy to write good tests.
Basically I just consolidated CoreUnitTestCase, UnitTestCase, and
ServiceTestBase into a single class named ServiceTestBase. I also
simplified some of the configuration creation methods to reduce
duplicated code.
This commit is a simple mv of the files.. We required two commits to preserve history,
one to git mv, one for the actual changes...
otherwise history would be lost
Based on the Apache ActiveMQ community vote this project is being
renamed "Artemis."
When sending a large message that exceeds the size of
Integer.MAX_VALUE, the bridge will get negative chunk size during
fowarding. And the resend cache is not limited so there is a
potential that it may get OutOfMemory exception.
this is basically addressing a performance issue on OpenWire, setting the auto-create to the PostOffice
after not being able to route
The core protocol stays the same in regard to the auto-create since the exceptions are happening after the queueQuery
Sometimes /tmp doesn't support ext4 (tmpfs) and there's always a risk of leaving unnatended files in cases of crashed.
This is in alignment with how other tests run at apache
If a Transaction wasn't created, the case for duplciate Detection would cancel a transaction that never happened
and it would get a NPE instead of a TX Exception.
It wasn't a big deal as the client got an exception anyways and the users were able to cancel in that case
but the message sent was a string containing just "Null".
this will fix it with a proper handling
https://issues.apache.org/jira/browse/ACTIVEMQ6-95
The message.copy is broken when you set persistence=false, and the bridge will use that method before forwarding the message
this commit is fixing NullStorageLargeServerMessage.copy and adding the proper testcase to validate the fix
https://issues.apache.org/jira/browse/ACTIVEMQ6-89
I have done a lot of refactoring on this. So we can a different version of the interceptor for each protocol based on a base class now.
Just an abstract class over Stomp would be a bit hacky... this is a better approach.
- Bumped up version to 2.0.0.Alpha
- Client bundle changes to be copmatible with 2.0.0
- Fixing bundle / Logging classes for missing format (it was an issue with the previous one already)
- Fixed up dependencies to avoid transient downloads
- removing unused methods
- moving JMSXdeliveryCountTest to /extra-tests
- A few transactions methods that were not being used and creating issues to the release
due to an old dependency to the TM
This closes#173
Returns an error to the client causing InvalidDestinationException to be
thrown when an ActiveMQ 5.x client attempts to create a producer with a
destination that does not exist. (Over OpenWire Protocol).
This was causing issues with javadoc
utils is also a package on activemq-server. ActiveMQUtilLogger is using a super class that was not part of the
source path on the javadoc plugin what caused it to exception and interrupt building
Fixing the classpath so some tests would find the LogManager configured
Fixing the dependency on the AssertionLoggerHandler so all the tests could also see it without further errors
My previous commit broke the location of the ServiceUtil / TransactionManagerLocator
This commit is setting a new DummyTM on the integration-tests-suite and the proper TM Locator on the extra-tests
With these changes the testsuite is not using any LGPL code by default. Anything woud go through extra-tests
These following changes were made on this commit (in summary):
- renamed byteman-tests as extra-tests
- added extra-tests on a new profile called extra-tests
- added all the other tests back to the tests profile
- removed concurrent-tests and moved them all to timing-tests
- removed old tests that were ignored for a long time and were stale
In some cases the ID Generator will be called after the JournalStorage was stopped.
AS a result you could have cases where the ID generator is called and the journal storage is stopped.
Also I added some check to IDs and added some code to cleanup old IDS on the BatchIDManager
Remove the reference to the JBoss Maven repo, and make all the necessary
adjustments on the child-projects. It turns out we don't even need the
security dependencies in the tests.
Implements a new feature for the broker whereby it may automatically
create and delete queues which are not explicitly defined through
the management API or file-based configuration when a client sends a
message to or receives from a queue via the AMQP protocol. Note,
the destination has to be named like "jms.queue.*" to be auto-
created. The queue may subsequently be deleted when it no longer has
any messages and consumers. Auto-creation and auto-deletion can both
be turned on/off via address-setting.
https://issues.apache.org/jira/browse/ACTIVEMQ6-7
Connection Factory is now externalizable and is now serialized as a string that represents a URI. There are schemas for every possible type for connection factory and server locator.
The client JNDI representation of factories has also been changed to be consistent with this.
This test started to fail after performance improvements from ACTIVEMQ6-78
After some investigation it turned out that this test was racing with the client
crashing even before the queue was created or sending a non persistent message
asynchronously while the client crashed before the server received the message.
I've also decreased some of the times on pings so the test could run a bit faster
Implements a new feature for the broker whereby it may automatically
create and delete queues which are not explicitly defined through
the management API or file-based configuration when a client sends a
message to or consumes from a queue via the STOMP protocol. Note,
the destination has to be named like "jms.queue.*" to be auto-
created. The queue may subsequently be deleted when it no longer has
any messages and consumers. Auto-creation and auto-deletion can both
be turned on/off via address-setting.
A transaction manager is only required on the JMSBridge when the QoS
level is set to ONCE_AND_ONCE_ONLY. Previous to the this patch it was
also checking for a TM on the AT_MOST_ONCE QoS level. This patch also
ensures that the TM is set to null after each test run.
These tests were not as broken as on 2.3.x from the old hornetq branch where this fix originated.
However I will play safe here as I believe the race could be after the exception is raised and before the counter was added
(on ActiveMQMessageHandlerTest)
Implements a feature whereby the broker will not shutdown while there are
clients connected. A timeout can be specified so that even if there are
clients connected the broker will still shutdown after a certain time.
Some of the OutgoingConnection and RA tests were failing due to a
previous transaction being present when using the Arjuna TM. This patch
adds methods to allow tests which TM to use and ensures that Dummy TM is
cleaned up each after each test.
https://issues.apache.org/jira/browse/ACTIVEMQ6-67
fixed distribution so that file based security works and hot deployers as broken and no longer needed with new bootstrap.
Also combined the jms and core configuration files.

The logic on transferring method is a bit complex, where
I found a better way to calculate the targetIDs.
This will also fix a few ScaleDownTests
I also added some extra tests using ScaleDownDirect
Some of the outgoing connection tests require a dummy transaction
manager to setup a fake transaction. The default transaction manager is
set to the JBoss TX manager and so the tests were failing. This patch
split the OutgoingConnectionTest into ones that require a real TM
manager vs Dummy TM Manager.

The redelivery list was not isolated on the PageIterator. This is moving the
redelivery list to the Iterator so we would have proper isolation of the functionality.
The previous version was assuming a single instance of PageIterator, QueueImpl and PageSubscription.
When we started using more than one instance of the Iterator we created this bug.
- added missing license headers found by maven rat plugin.
most of them added automatically via apache-rat
a few manually added
- added apache-rat maven plugin to the build cycle
on the replication channel
The connection-ttl and client-failure-check-period are not passed
to the server locator used to create replication connection. So the
fix sets the two parameters in SharedNothingBackupActivation.
Some tests require a proper TM to be returned by the TMLocator
implementation whilst others require a DummyTM to be returned. This
patch makes allows TM returned by the locator class to be changed by the
test.

Changing the order of depaging introduced an extra check that needs to be checked now.
This will probably take care of the issue by checking if the page is complete before depage.
Pulls out WildFly XA Recovery specifics into a different project. Some
XA recovery code is still present and is used as integration points for
integrating TM XA recovery processes.
https://issues.apache.org/jira/browse/ACTIVEMQ6-6
Removed the jboss security implementations and also implemented the location of Transaction Managers using Service Loader and removed the jboss implementation.
https://issues.apache.org/jira/browse/ACTIVEMQ6-54
This is fixing a few issues around paging:
- Browsing it not looking towards Paging. I'm using the queue.totalIterator which is a read-only iterator that goes towards the pages messages.
- Depage is not kicking correctly in some scenarios. I have improved the logic on scheduling depage for that.
https://issues.apache.org/jira/browse/ACTIVEMQ6-20
this has been identified as a dead feature.
It was only useful for presentations...
it had its time and we have better examples we can use...
It's time for this feature to go!
Adds a new service extensions components used to house any extension
points for integration and extension. In addition this patch adds
initial extension points for XAResource wrapping.

We are renaming packages from activemq6 to activemq as that's more generic and version independent
The previous commit renamed the directories. On this commit now I'm changing the code.
If we changed the code and the directories on the same commit git would remove and add a lot of files
without recognizing the renames.

We are renaming packages from activemq6 to activemq as that's more generic and version independent
On this first commit I'm just renaming the directories otherwise the history would be lost. The next commit will rename the text on the directories.
If I squash these two commits git will make us delete / add again.
