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.
