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.
In a cluster if a node is shut down (or crashed) when a
message is being routed to a remote binding, a internal
property may be added to the message and persisted. The
name of the property is like _AMQ_ROUTE_TOsf.my-cluster*.
if the node starts back, it will load and reroute this message
and if it goes to a local consumer, this property won't
get removed and goes to the client.
The fix is to remove this internal property before it
is sent to any client.
remove custom repo
update groupid to match artifact in maven central.
bump version also to that now deployed to maven central.
bump checkstyle version to 7.7 to make compatible.
updated checkstyle.xml to ignore existing issues which are prolific
which are now flagged in latest version as some bugs in previous meant they we'ren't detected e.g. https://github.com/checkstyle/checkstyle/issues/3320
fixing some violations which are not too prolific.
This commit has 2 changes for backwards compatibility with older
clients:
1) A "bindings query" will now detect if the client is both JMS and
"old" (i.e. pre-2.0) and will prefix the returned queue names with the
old prefix (i.e. "jms.queue."). This will allow the old client to
properly detect whether or not a queue exists in its auto-creation
logic.
2) When messages are dispatched to a consumer there is logic to detect
if the consumer is both JMS and "old" and will prefix the "address"
on the message with "jms.queue." or "jms.topic." as appropriate
(if it's not already prefixed).
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.
The empty folder artemis-server/artemis-load-generator seems to be a
git submodule link. However, there is no submodule configuratation
file (ie .gitmodules) in this repository.
This caused the 'git submodule' command to fail with the following
error message:
fatal: no submodule mapping found in .gitmodules for path 'artemis-server/artemis-load-generator'
Added a wait-for-activation option to shared-store master HA policies.
This option is enabled by default to ensure unchanged server startup behavior.
If this option is enabled, ActiveMQServer.start() with a shared-store master server will not return
before the server has been activated.
If this options is disabled, start() will return after a background activation thread has been started.
The caller can use waitForActivation() to wait until server is activated, or just check the current activation status.
Adding a new ActievMQServerPlugin interface to support adding custom
behavior to the broker at certain events such as connection or session
creation.

Use `long` array for hourly counters instead of `int` array.
Prevents overflow when the number of new messages (a `long`) is added.
Fixes one of the "Implicit narrowing conversion in compound assignment"
alerts on https://lgtm.com/projects/g/apache/activemq-artemis/alerts.
Have `AddressControlImpl::getMessageCount` use and return a `long`.
Prevents potential overflow from use of an `int` count variable.
Fixes one of the "Implicit narrowing conversion in compound assignment"
alerts at https://lgtm.com/projects/g/apache/activemq-artemis/alerts.
Instead of going directly into backup mode within the shared-store
live activation, we just change the HA-policy to slave and return
to the caller - ActiveMQServerImpl.internalStart().
The caller will then handle the backup activation as usual
in a separate thread, such that EmbeddedJMS.start() can return.
Also added a related integration test.
sendMessage() may throw ActiveMQException that causes CNFE
at the management client. Also it should check if headers
in the message is null (to prevent NPE).
The ActiveMQJAASSecurityManager class uses LoginContext to validate
users and roles. LoginContext loads LoginModule classes defined in
the configuration (login.config) using current thread's context
classloader.
Normally this wouldn't be a problem but when a caller thread comes
from JMX (for example a client calls QueueControl.sendMessage() via
JMX) the caller thread has a different context class loader.
This will cause the LoginContext to fail to load the LoginModule
class (e.g. PropertiesLoginModule) and the validation will fail
even if correct credentials are supplied.
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.
AIOFileLockManager doesn't work on NFS-mounted share store directories.
Since the GFS2 bug https://bugzilla.redhat.com/show_bug.cgi?id=678585
has been fixed end of 2011, the class AIOFileLockManager is no longer needed and I have removed it.

Add tests for this management operation with both core and AMQP encoded
messages. Also fix a few problems with the implementation like not
checking the passed-in headers for null and not counting messages
properly.
When a replica attempts to connect to a live server using a group-name
and there are > 1 servers on the network using that group there is a
chance it will fail because it doesn't keep track of all of the
topology data it receives. This fix ensures that all the topology data
from the cluster tracked until it is used and fails at which point it
is discarded.
When populate-validated-user = true AMQP messages can cause exceptions.
This feature isn't particularly applicable to AMQP so this commit
eliminates the exception and leaves the AMQP messages untouched
even if populate-validated-user = true. In other words,
populate-validated-user + AMQP is not supported.
If broker fails to decode any packets from buffer, it should
treat it as a critical bug and disconnect immediately.
Currently broker only logs an error message.
The following changes are made to support Epoll.
Refactored SharedNioEventLoopGroup into renamed SharedEventLoopGroup to be generic (as so we can re-use for both Nio and Epoll)
Add support and toggles for Epoll in NettyAcceptor and NettyConnector (with fall back to NIO if cannot load Epoll)
Removal from code of PartialPooledByteBufAllocator, caused bad address when doing native, and no longer needed - see jira discussion
New Connector Properties:
useEpoll - toggles to use epoll or not, default true (but we failback to nio gracefully)
remotingThreads = same behaviour as nioRemotingThreads. Previous property is depreated.
useGlobalWorkerPool = same behaviour as useNioGlobalWorkerPool. Old property is deprecated.
New Acceptor Properties:
useEpoll - toggles to use epoll or not, default true (but we failback to nio gracefully)
useGlobalWorkerPool = same behaviour as useNioGlobalWorkerPool but for Epoll.
This closes#1093
Adjust slow-consumer detection logic to use the number of messages in
the queue and not just the number of messages added since the last
check. This means the getRate() method now returns the rate of messages
which it *could* have dispatched since the last check rather than the
rate at which it received messages. This is a more reliable metric to
ensure the slow-consumer detection logic doesn't flag a consumer as
slow unfairly. Although the reliability will come at a performance cost
since getMessageCount() must lock the queue.
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.
Artemis expose createQueue() method to management console like Jon.
If the queue to be created already exists it throws an ActiveMQException
back to the console, which will get a ClassNotFoundException when
deserializing the exception.
The same issue goes also with AddressControl.sendMessage() method.
To fix that it should throw a common java exception like IllegalStateException.
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.
In a cluster of replicated live/backup pairs if a backup crashes and
then its live crashes the cluster will retain the topology information
of the live such that when the live server restarts it will check the
cluster to see if its nodeID is present (which it will be) and then it
will activate as a backup rather than a live. To prevent this situation
an additional check is necessary to see if the server with the matching
nodeID is actually active or not which is done by attempting to make a
connection to it.
remove reconnect attempt as it serves no purposes as replication has stopped anyway.
Ensure if vote fails thatthe latch is counted down to avoid delay.
If we can't detect live has failed signal failure in replicating.

- 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
Removes cyclic dependencies between classes and packages in the artemis-jdbc-store projetct by moving classes and methods to other locations and reducing the visibility of classes, fields and methods. Solving cyclic dependencies is important to keep the codebase maintainable. Scenarios where "everything uses everything" should be avoided.
Two issues encountered here:
i - ClosingConnectionTest was intermittently breaking other tests, in particular it was breaking PagingLeakTest for no apparent reason
. apparently it was a dead lock from removeAddress on the ServerController
ii - it still showing issues after removing the not needed synchronziation. Since the test is not really needed I am just removing the offending test.
* Do not offset ports for Netty connector/acceptor with http-upgrade
enabled.
* Pass the name of the ActiveMQ server to the HTTP request to initiate
the Upgrade so that the HTTP endpoint on the app server can find the
correct ActiveMQ broker that must handle the upgrade.

If the path to file contains some special characters, they are encoded
in URL form using %<hex> syntax. We should decode such path when it
is used as path to file on local filesystem.
* add DataSource property to DatabaseStorageConfiguration to be able to
communicate with the data store using this DataSource instance instead
of relying on the creation the SQL connnection using the JDBC connection
URL/driver class name tuple.
* add SQLProvider.Factory property to DatabaseStorageConfiguration to
externalize the choice of the SQLProvider instead of relying on
hard-coded choices. If the property is null, the current behaviour will
be used (determing the SQLProvider based on the driver class name)
* bindingsJournal and messageJournal are already started in the start()
method. Remove redundant calls that were creating unused JDBC
connections that are never closed.

max-disk-usage = how much of a disk we can use before the system blocks
global-max-size = how much bytes we can take from memory for messages before we start enter into the configured page mode
This will also change the default created configuration into page-mode as that's more reliable for systems.
