Refactored thread local ByteBuffer pooling, alignment
and zeroing in order to avoid duplicate code and
improve code coverage with tests.
In addition are being provided faster branchless
alignment operations and optional zeroing of
pooled ByteBuffers for both ASYNCIO and
NIO/MAPPED journal types.
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.
* Using SpawnedVMSupport (used to be on testsuite, moving it to Utils)
* Building the classpath for ./lib, similar to what happens on Bootstrap
* Using Path as much as possible to avoid issues encoding files
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 pattern has been
replaced by an atomic checkProperties().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
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.
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
GlobalDiskFullTest was broken before this fix.
Basically when using multiple addresses over a session you would miss flow credits on all your producers except to the first one
that ran out of credit.
Add Concurrency Test to expose concurrency errors seen in logs.
Add Fix to ensure TypedProperties to ensure threadsafety
Add forEach and forEachKey to allow for provide a thread safe way of iterating through keys and values, without needing to duplicate the collection.
Add getMapNames method to remove code duplication and to ensure thread safe
Currently we get.

Replace guava Preconditions with artemis Preconditions
Replace guava Predicate with java Predicate
Replace guava Ordering with java Comparator
Replace guava Immutable, with ArrayList/Set and then wrap with unmodifiable
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
Most of the visibility guarantees of size/capacity fields modifications are already provided through optimistic locking, hence it could be used it instead of volatile set(s) on put/remove, making those methods more efficient.
Logging for the "fast-tests" profile used for PR builds could be reduced
significantly. This would save time as well as prevent log truncation
(Travis CI only supports logs up to 4MB).
Support exlusive consumer
Allow default address level settings for exclusive consumer
Allow queue level setting in broker.xml
Add the ability to set queue settings via Core JMS using address. Similar to ActiveMQ 5.X
Allow for Core JMS client to define exclusive consumer using address parameters
Add tests
We provide a feature to mask passwords in the configuration files.
However, passwords in the bootstrap.xml (when the console is
secured with HTTPS) cannot be masked. This enhancement has
been opened to allow passwords in the bootstrap.xml to be masked
using the built-in masking feature provided by the broker.
Also the LDAPLoginModule configuration (in login.config) has a
connection password attribute that also needs this mask support.
In addition the ENC() syntax is supported for password masking
to replace the old 'mask-password' flag.
The UTF translations has been improved by:
- zero copy on array based buffers
- zero copy UTF length calculation
- faster array access using Netty PlatformDependent.get|putByte
- improved perf tests UTF8Test
* Move byte util code into ByteUtil
* Re-use the new equals method in SimpleString
* Apply same pools/interners to client decode
* Create String to SimpleString pools/interners for property access via String keys (producer and consumer benefits)
* Lazy init the pools on withing the get methods of CoreMessageObjectPools to get the specific pool, to avoid having this scattered every where.
* reduce SimpleString creation in conversion to/from core message methods with JMS wrapper.
* reduce SimpleString creation in conversion to/from Core in OpenWire, AMQP, MQTT.
Apply fix so that when using JNDI via tomcat resource it works.
Replace original extract of JNDIStorable taken from Qpid, and use ActiveMQ5's as fits better to address this issue. (which primary use case is users migrating from 5.x)
Refactored ActiveMQConnectionFactory to externalise and turn into reference by StringRefAddr's instead of custom RefAddr which isnt standard.
Refactored ActiveMQDestinations similar
Refactored ActiveMQDestination to remove redundent and duplicated name field and ensured getters still behave the same
Instead of flushing we just need to make sure there are no more calls into
page executors as we stop the PageManager.
This will avoid any possible starvations or deadlocks here.
The timeout logic is changed to use System::nanoTime, less sensible to OS clock changes.
The volatile set on CriticalMeasure are changed with cheaper lazySet.
Instead of wait to flush an executor,
I have added a method isFlushed() which will just translate to the
state on the OrderedExecutor.
In the case another executor is provided (for tests) there's a delegate
into normal executors.
This is replacing an executor on ServerSessionPacketHandler
by a this actor.
This is to avoid creating a new runnable per packet received.
Instead of creating new Runnable, this will use a single static runnable
and the packet will be send by a message, which will be treated by a listener.
Look at ServerSessionPacketHandler on this commit for more information on how it works.
If replication blocked anything on the journal
the processing from clients would be blocked
and nothing would work.
As part of this fix I am using an executor on ServerSessionPacketHandler
which will also scale better as the reader from Netty would be feed immediately.
We recently moved TypedProperties under ./util/collections
This is exposed through Messages so we added this as a deprecated option.
We also had to add this class on a separate commit from dc26ac96b4
to preserve git history on the new one.
Building on ARTEMIS-905 JCtools ConcurrentMap replacement first proposed but currently parked by @franz1981, replace the collections with primitive key concurrent collections to avoid auto boxing.
The goal of this is to reduce/remove autoboxing on the hot path.
We are just adding jctools to the broker (should not be in client dependencies)
Like wise targeting specific use case with specific implementation rather than a blanket replace all.
Using collections from Bookkeeper, reduces outside tlab allocation, on resizing compared to JCTools, which occurs frequently on testing.
- NIO/ASYNCIO new TimedBuffer with adapting batch window heuristic
- NIO/ASYNCIO improved TimedBuffer write monitoring with
lightweight concurrent performance counters
- NIO/ASYNCIO journal/paging operations benefit from less buffer copy
- NIO/ASYNCIO any buffer copy is always performed with raw batch copy
using SIMD instrinsics (System::arrayCopy) or memcpy under the hood
- NIO improved clear buffers using SIMD instrinsics (Arrays::fill) and/or memset
- NIO journal operation perform by default TLABs allocation pooling (off heap)
retaining only the last max sized buffer
- NIO improved file copy operations using zero-copy FileChannel::transfertTo
- NIO improved zeroing using pooled single OS page buffer to clean the file
+ pwrite (on Linux)
- NIO deterministic release of unpooled direct buffers to avoid OOM errors
due to slow GC
- Exposed OS PAGE SIZE value using Env class
Broker should support full qualified queue names (FQQN)
as well as bare queue names. This means when clients access
to a queue they have two equivalent ways to do so. One way
is by queue names and the other is by FQQN (i.e. address::qname)
names. Currently only receiving is supported.
This is fixing an issue introduced on 4b47461f03 (ARTEMIS-822)
The Transactions were being looked up without the readLock and some of the controls for Read and Write lock
were broken after this.

This is now considering only threads waiting for the queue to get new tasks as idle.
The thread pool maintained a counter of active threads, but that counter was increased
too late in the beforeExecute method. Submitting a task created a new thread.
If now a second task was submitter before the new thread had started to execute it's task,
the second task was queued without creating a 2nd thread. So the second task was only
executed after the first task had been completed - even if the thread pool's
maximum number of thread had not been reached.
This fix now maintains the delta between the number those threads that are currently waiting
in the queue's poll or take methods as idle threads, and the number of queued tasks.
It creates new threads unless there are enough idle threads to pick up all queued tasks.
This closes#1144
with this we could send and receive message in their raw format,
without requiring conversions to Core.
- MessageImpl and ServerMessage are removed as part of this
- AMQPMessage and CoreMessage will have the specialized message format for each protocol
- The protocol manager is now responsible to send the message
- The message will provide an encoder for journal and paging
Due to recent changes, the web component is shutdown by the
server, but the shutdown flag is lost so the web component's
cleanup check method is not get called and the web's tmp
dir is left there after user stopped the broker (control-c).
The fix is add a suitable API to allow passing of the
flag so the web component can make sure its tmp dir gets
cleaned up properly before exiting the VM.
- user passwords for PropertiesLoginModule stored using PBKDF2 algothrim
by default
- implements cli user command to help create and manage user/roles
- adds a mask cli command to mask passwords
Since we don't need client implementations any longer, given the maturity level of
qpid jms, these classes can go, as a result a lot of the interfaces can be removed.
As part of this I am removing proton-plug, and reorganizing the packages in a way I think it
makes more sense and easier to other developers to understand and maintain it.

Javax.json is a newer JSR, but has an ASF compliant version, is pretty close to the original JSON.org API and will support a standard annotation based JSON-B solution at some point soon.
Updated integration tests and removed JSON.org from license.
Using array() is a bit dangerous as it's an optional part of any
ByteBuffer implementation. This new method will deal with various
ByteBuffer implementations appropriately.
- Added a thread pool executor, that combines cached and fixed size thread pooling.
It behaves like a cached thread pool in that it reuses exising threads and removes
idle threads after a timeout, limits the maximum number of threads in the pool, but
queue additional request instead of rejecting them.
- changed existing code to use the new thread pool instead of a fixed-size thread pool in
all places that are configured with a client thread pool size.
Previously, the order of query parameters depended on the iteration order of items in a Set.
This order is undefined for some Sets. Nevertheless, unit test for createQueryString expected
that query parameters are in a particular order.
Previously we were using a long regular expression to detect whether or not a
given host was IPv6. However, this was brittle and hard to read. Since we are
already shipping Google Guava in the distribution it made sense to use the
Guava method com.google.common.net.InetAddresses#isInetAddress rather than
the regular expression.
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
"mvn install" now works without the lint, but a "mvn install javadoc:jar" still fails. Since that is what the release plugin uses, need to keep the lint there for now. Still lots of failures.
To reproduce this commit, apply a replace regex rule using:
search regex: /\*\*\n \* Licensed
replace: /\*\n \* Licensed
These files had to be changed manually:
artemis-selector/src/main/javacc/HyphenatedParser.jj

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."
