Check for AMQSession being null before handling various TX state checks
in order to ensure the correct errors are thrown and TX rollback is
handled properly.
OpenWireFormat instances are shared between OpenWire connections/sessions/consumers, preventing the clients to scale due to the synchronized marshal/unmarshal on it.
It includes:
- direct transport buffer pooling
- groupId SimpleString pooling
- clientId SimpleString pooling
- reduced ActiveMQDestination[] and AtomicLong allocations on AMQSession:send
- reduced ActiveMQDestination allocations
- refactored shouldBlockProducer path of AMQPSession::send to reduce method size
- exclusive OpenWireFormat per session and connection (in/out) to avoid contention
- refactored trace log to favour inlining
- changed lastSent volatile set into lazy set to avoid full barrier cost on x86
- stateless OpenWireMessageConverter
- send's lock removal thanks to thread-safe NettyConnection
Adding new metrics for tracking message counts and sizes on a Queue.
This includes tracking metrics for pending, delivering and scheduled
messages. The paging store also tracks message size now.
* 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.
When openwire client uses compressed option to send messages
(jms.useCompression=true) openwire client failed to receive them.
The reason is in OpenwireMessageConverter.toAMQMessage():
1. message.setContent() should be called after setting properties
(It will cause the compressed content to decompressed before delivering to clients)
2. message.onSend() should not be called here (it should be used
by producers. If used here it changes the internal flags of the
message and cause receive to fail).
Openwire clients create consumers to advisory topics to receive
notifications. As a result there are internal queues created
on advisory topics. Those consumer shouldn't be exposed via
management APIs which are used by the Console
To fix that the broker doesn't register any queues from
advisory addresses.
Also refactors a code to remove Openwire specific contants
from AddressInfo class.
If message senders and receivers uses different
wireformat.tightEncodingEnabled options, broker will get marshalling
problem. This is because when openwire messages are converted to
core messages, and later these core messages converted to openwire
messages, the broker uses a mashaller that comes with the connection
used to carry the messages.
For example, if a producer sents a message using option "wireformat
.tightEncodingEnabled=false" and a receiver tries to receive it
using 'true' for the same option, it'll never get it because the
broker will fail to use a "tight encoding" marshaller to
decode a 'loose encoded' message.
To fix the problem, we always use 'tight encoding' for internal
message converters.
Remove some redundant code in the processing of the OpenWire Destination
name, both in the topic handler and in the method in general the
destination name only needs to be converted once and only one
SimpleString instance needs to be created from that which will then feed
all the places that either the String form or the SimpleString form of
the result is needed.
By default, every openwire connection will create a queue
under the multicast address ActiveMQ.Advisory.TempQueue.
If a openwire client is create temporary queues these queues
will fill up with messages for as long as the associated
openwire connection is alive. It appears these messages
do not get consumed from the queues.
The reason behind is that advisory messages don't require
acknowledgement so the messages stay at the queue.
delegate to the jdk saslServer. Allow acceptor configuration of supported mechanismis; saslMechanisms=<a,b>
and allow login config scope for krb5 to be configured via saslLoginConfigScope=x
Add krb5sslloginmodule that will populate userPrincipal that can be mapped to roles independently
Generalised callback handlers to take a connection and pull certs or peerprincipal based on
callback. This bubbled up into api change in securitystore and security manager
Use AcitveMQDestination for subscription naming, fixing and aligning queue naming in the process.
The change is behind a configuration toggle so to avoid causing any breaking changes for uses not expecting.
As part of my refactoring on AMQP, the broker shouldn't rely on Application properties
for any broker semantic changes on delivery.
I am removing any access to those now, so we can properly deal with this post 2.0.0.
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
When openwire sends back an exception response, it doesn't set
the correct correlation id. This causes the client to miss the
response and the exception won't get caught.
To fix it we need to add the correlation id before sending.
When sending an empty ObjectMessage, broker doesn't
write a 'length' field to the message buffer. In delivery
the broker tries to read the length from the buffer, which
causes "IndexOutOfBoundsException".
To fix it, we need to check if the buffer is empty or not,
and only read it if the buffer is not empty.
When a producer sends a messages to a temp destination created from
another connection, it fails. The reason behind it is that the
producer's connection didn't receive the advisory message (notification)
from broker about this temp destination, and it will throw an exception
if it doesn't know this temp destination.
The fix is send the advisory to the client so that it knows this destination.
When creating a 'no-local' openwire consumer, it doesn't work,
meaning it can still receive messages from the same connection.
The fix is similar to what Artemis client does, which is adding
a 'filter' to the consumer/subscription.
The difference is that with OpenWire we have to do it on the
broker side.
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.

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 is doing some refactoring, making the SecurityStore mechnism possible to be reused on other protocols,
without forcing them to implement ServerSession on checks that won't fit the Server Model from Artemis
-Using core api to inspect queue status
-Catch command visit() exceptions in order to
pass it back to client.
-Correct destination add/remove handlings
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-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.
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
artemis-selector/src/main/javacc/StrictParser.jj
artemis-website/src/main/resources/styles/impact/css/pygmentize.css

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."
