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 pattern has been
replaced by an atomic checkProperties().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.
In Page.write(final PagedMessage message) if the page file is closed
it returns silently. The caller has no way to know that if the message
is paged to file or not. It should throw an exception so that the
caller can handle it correctly.
This causes random failure PagingTest#testExpireLargeMessageOnPaging().
The test shows that when the server stops it closes the page file.
In the mean time a message is expired to the expiry queue and if
the expiry queue is in paging mode, it goes to Page.write() and
returns without any error. The result is that the message is removed
from the original queue and not added to the expiry queue.
If we throw exception here it makes the expiration failed, the message
will not be removed from the orginal queue. Next time broker is started,
the message will be reloaded and expired again. no message lost.
Add consumer priority support

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.
There were two different but nearly identical implementations of
createQueue(). I consolidated these into a single method. There should
be no semantic differences.
When trying to get the bindings for an address the getBindingsForAddress
method will create a Bindings instance if there are no bindings for the
address. This is unnecessary in most circumstances so use the
lookupBindingsForAddress method instead and check for null.
MULTICAST messages forwarded by a core bridge will not be routed to any
ANYCAST queues and vice-versa. Diverts have the ability to configure how
routing-type is treated. Core bridges now support this same kind of
functionality. By default the bridge does not alter the routing-type of
forwarded messages to maintain compatibility with existing behavior.
Large messages pendingRecordID is not accessed atomically, leading
to races that would lead to records that cannot been found on the
journal for deletion: it would lead to cause NPE that won't clean
the pending tasks on the current OperationContextImpl.
Adding a cleanup on error of those tasks and avoiding the race
to happen by adding proper synchronization will both enforce
correct clean up when something bad happen and avoid NPE.
In PagingManagerImpl#getPageStore() the operations on the map 'stores'
are not synchronzed and it's possible that more than one paging store is
created for one address.
PageSubscriptionImpl::ackTx is already performing a counter update
using the message persistent size: the size can be reused on
PagePosition::setPersistentSize, avoiding to query the page cache just
to compute it.
These improvements were also part of this task:
- Routing is now cached as much as possible.
- A new Runnable is avoided for each individual message,
since we use the Netty executor to perform delivery
https://issues.apache.org/jira/browse/ARTEMIS-2205
TransactionImpl::properties are often not used and could be
avoided to be allocated.
OperationContextImpl.TaskHolders instances are turned into static
classes to avoid refecencing back the context, making the life
easier for the GC.
OperationContexImpl volatile loads can be reduced to make the
code faster on the hot path.
When a receiving transaction is committed in a paging situation,
if a page happens to be completed and it will be deleted in a
transaction operation (PageCursorTx). The other tx operation
RefsOperation needs to access the page (in PageCache) to finish
its job. There is a chance that the PageCursorTx removes the
page before RefsOperation and it will cause the RefsOperation
failed to find a message in a page.
When a node tries to reconnects to another node in a scale down cluster,
the reconnect request gets denied by the other node and keeps retrying,
which causes tasks in the ordered executor accumulate and eventually OOM.
The fix is to change the ActiveMQPacketHandler#handleCheckForFailover
to allow reconnect if the scale down node is the node itself.
Not closing the InputStream makes this test flaky on Windows. The test
breaks because FileMoveManager::delete(java.io.File) Line 221 fails
to delete the file if it's still "owned" by the JVM process on Windows.
With AMQP protocol when some messages are received in a transaction,
calling JMX QueueControl.listDeliveringMessages() returns empty list
before the transaction is committed.

Any failure to deploy an address or queue will short-circuit the broker
initialization process preventing any other addresses or queues from
being deployed as well as other critical resources like acceptors, etc.
The ServerSessionPacketHandler has a close() callback handler which will
delete any pending large messages. However, there is a race where a
large message can be routed, then the close delete the associated large
message resulting in data loss.
First, QueueQuery should use address name for address settings

Seperate plugin interface by area, all extending a base interface.
Update code to check and call only plugins implementing specific interfaces.
Existing interface extends all the new interfaces for back compatibility or those who want simplicity and don't care about perf.
This commit adds support for tracking metrics for bridges for both
normal bridges and bridges that are part of a cluster. The two
statistics added in this commit are messages pending acknowledgement
and messages acknowledged but more can be added later.
Anonymous senders (those created without a target address) are not
blocked when max-disk-usage is reached. The cause is that when such
a sender is created on the broker, the broker doesn't check the
disk/memory usage and gives out the credit immediately.
Fix so that it only updates if not null, to avoid user being unset from existing api's,
This is similar to other values, that only change the value when not null.
This reverts commit c3fbd1b9e4.
Based on the discussion on the PR
https://github.com/apache/activemq-artemis/pull/2035 this shouldn't have
been merged. It's importing JMS-specific code into the core broker which
is something we've worked hard to eliminate in recent releases.

Authentication failures are currently only logged for CORE clients.
This change puts the logging in a central location which all protocols
use for authentication so that authentication failures are logged for
all protocols.
Calling close multiple times on ServerConsumer can result in multiple
notifications being routed around the cluster. This causes cluster
topology info to become skewed. Which affects a number of components
such as message redistribution, metrics and can eventually cause OOM
should multiple queues be redistributing at the same time.
After sending pages, the thread will hold the storage manager write lock
and send synchronization finished packet(use the parent thread pool) to
the backup node. At the same time, thread pool is full bcs they are
waiting for the storage manager read lock to write the page or journal,
leading to replication starting failure. Here we use io executor to send
replicate packet to fix thread pool starvation problem.
Quorum voting is used by both the live and the backup to decide what to do if a replication connection is disconnected.
Basically, the server will request each live server in the cluster to vote as to whether it thinks the server it is replicating to or from is still alive.
You can also configure the time for which the quorum manager will wait for the quorum vote response.
Currently, the value is hardcoded as 30 sec. We should change this 30-second wait to be configurable.
When setting "default-max-consumers" in addressing setting in broker.xml
It has no effect on the "max-consumers" property on matching address queues.
Tests added as part of a previous commit
This closes#2107
1. Add tests case to verify issue and fix, tests also tests for same behavior using CORE, OPENWIRE and AMQP JMS Clients.
2. Update Core Client to check for queue before creating, sharedQueue as per createQueue logic.
3. Update ServerSessionPacketHandler to handle packets from old clients to perform to implement the same fix server side for older clients.
4. Correct AMQP protocol so correct error code is returned on security exception so that amqp jms can correctly throw JMSsecurityException
5. Correct AMQP protocol to check for queue exists before create
6. Correct OpenWire protocol to check for address exists before create
When database persistence and no shared store option is being used,
Artemis is choosing to use InVMNodeManager, that is not providing
the same behaviour of FileLockNodeManager.
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
PageCursorProviderImpl is not handling any pending cleanup tasks
on stop, leaving paging enabled due to the remaining pages to be
cleared up.
PagingStoreImpl is responsible to trigger the flushing of pending
tasks on PageCursorProviderImpl before stopping it and to try to
execute any remaining tasks on the owned common executor, before
shutting it down.
It fixes testTopicsWithNonDurableSubscription.
NotificationActiveMQServerPlugin and LoggingActiveMQServerPlugin are
implementing the deprecated version of
ActiveMQServerPlugin::messageExpired that is not called by the
new version of the method or any other part of the code
This fixing test org.apache.activemq.artemis.tests.integration.management.NotificationTest#testMessageExpired
It avoid using the system clock to perform the locks logic
by using the DBMS time.
It contains several improvements on the JDBC error handling
and an improved observability thanks to debug logs.
largeMessagesFactory::newBuffer could create a pooled direct ByteBuffer
that will not be released into the factory pool: using a heap ByteBuffer
will perform more internal copies, but will make it simpler to be garbage
collected.
QuorumFailOverTest.testQuorumVotingLiveNotDead fails
because the quorum vote takes longer time to finish than
the test expects to.
(The test used to pass until commit ARTEMIS-1763)
The previous commit about this feature wasn't using the row count query
ResultSet.
The mechanics has been changed to allow the row count query
to fail, because DROP and CREATE aren't transactional and immediate
in most DBMS.
It includes a test that stress its mechanics if used with DBMS like
DB2 10.5 and Oracle 12c.
Additional checks and logs have been added to trace each steps.
JdbcNodeManager is configured to use the same network timeout
value of the journal and to validate all the timeout values
related to a correct HA behaviour.
The JDBC Connection leaks on:
- JDBCFileUtils::getDBFileDriver(DataSource, SQLProvider)
- SharedStoreBackupActivation.FailbackChecker::run on a failed awaitLiveStatus
Expose method to return current mappings of groups to consumers
Expose methods to reset (remove) specific group mapping from groupID to Consumer
Expose methods to reset (remove) all group mappings
messageAcknowledged plugin callback methods
Knowing the consumer that expired or acked a message (if available) is
useful and right now a message reference only contains a consumer id
which by itself is not unique so the actual consumer needs to be passed
When finding out if a connector belong to a target node it compares
the whole parameter map which is not necessary. Also in understanding
the connector the best place is to delegate it to the corresponding
remoting connection who understands it. (e.g. INVMConnection knows
whether the connector belongs to a target node by checking it's
serverID only. The netty ones only need to match host and port, and
understanding that localhost and 127.0.0.1 are same thing).
The queue metrics were being decremented improperly because on iteration
over the cancelled scheduled messages because the flag for fromMessageReferences was not
set to false. Setting the flag to false skips over the metrics update
which is what we want as the scheduled messages were never added to the
message references in the first place so the metrics don't need updating
When creating a temp destination and auto-create-address set to false, the
broker throws an error and refuse to create it. This doesn't conform to
normal use-case (like amqp dynamic flag) where the temp destination should
be allowed even if the auto-create-address is false.
There was a logic to validate if member is null.
Which seemed a bit weird considering the else would throw a NPE.
Fixing it proactively based on Coverity-scan findings.
The cluster connection bridge has a TopologyListener and connects to a new node
each time it receives a nodeUp() event. It needs to put a check here to make
sure that the cluster bridge only connects to its target node and it's backups.
This issue shows up when you run LiveToLiveFailoverTest.testConsumerTransacted
test.
Also in this commit improvement of BackupSyncJournalTest so that it runs more
stable.
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
It allows a user to customize the max allowed distance between system and DB time,
improving HA reliability by shutting down the broker when the misalignment
exceeds configured limit.
In some environments it is not allowed to create a schema
by the application itself. With this change the AbstractJDBCDriver
now tests if an existing table is empty and executes further
statements in the same way as if the table does not exist.
It forces to use InVMNodeManager when no HA option is selected with JDBC persistence and includes the checks that the only valid JDBC HA options are SHARED_STORE_MASTER and SHARED_STORE_SLAVE.
The JDBC Lock Acquisition Timeout is no longer exposed to any user configuration and defaulted to infinite to match the behaviour of the journal (file-based) one.
When creting a durable topic subscription using the Artemis 1.x JMS
client library. The client sends a QueueQuery to the server to see if
the durable subsciption queue already exists. The broker then performs
some transformation of the queue addresses to suit the 1.x naming
scheme. However, if the queue does not already exist the transform is
attempted on a null string causing NPE. To fix we simply check that the
result return isExists=true.
Add Test Case to stop and restart server after config reload and check state, this re-creates network health check issue where config changes are lost when network health check de-activates the server and then re-activates.
Add fix to update the held configuration thats used when initialisation steps during start are done.
Free hash set used to hold page position for acks and removed refs.
The two set is cleared, but they still hold a big array.
It is safe to replace the old one with empty set.
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).
Revert #1875
This reverts commit 5ad45369ce.
The storage manager is broken now as the AddressManager change here is trying to insert a record on the journal before startup.
- LargeServerMessageImpl.finalize is eventually causing deadlocks
- CoreMessage needs to check properties before decoding
- PagingTest tweaks
- ServerLocatorImpl can deadlock eventually, avoiding a lock and using actors
- ActiveMQServerImpl.finalize is also evil and can cause deadlocks on the testsuite
- MqttClusterRemoteSubscribeTest needs to setup the Address now on the setup
The PageCountPendingImpl was increasing the encode size without using its full allocation.
This was causing issues on replication as the encode is also used to determine the size of the packets.
however the packets were not receive the full allocated data causing missing packets on the replication
and test failures.
This is fixing the issue
This is good when you are a customer and an artemis engineer (e.g. me) asks your journal print-data but you can't do it because that would expose your user's data. If you do artemis data print --safe, that will only expose the journal structure without exposing user's data and eliminate any liability between the engineer and users.
Transactions may initialize a PagedReference without a valid message yet
during load of prepared transactions.
Caching has to be lazy on this case and it should load on demand.
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.
Cache `messageID`, `transactionID` and `isLargeMessage`
in PagedReference, so that when acknowledge, we do not have to
get PagedMessage which may be GCed and cause re-read entire page.

Make sure that if a bridge disconnects and there is no record in the topology that it uses the original bridge connector to reconnect.
Originally the live broker that disconnected was left in the Topology, thie broke quorum voting as when th evote happened all brokers when asked though th etarget broker was still alive.
The fix for this was to remove the target live broker from the Topology. Since the bridge reconnect logic relied on this in a non HA environment to reconnect this stopped working.
The fix now uses the original target connector (or backup) to reconnect in the case where the broker was actually removed from the cluster.
