In case there is a hardware, firewal or any other thing making the UDP connection to go deaf
we will now reopen the connection in an attempt to go over possible issues.
This is also improving locking around DiscoveryGroup initial connection.
This is a Large commit where I am refactoring largeMessage Body out of CoreMessage
which is now reused with AMQP.
I had also to fix Reference Counting to fix how Large Messages are Acked
And I also had to make sure Large Messages are transversing correctly when in cluster.
- Avoid some Properties Decoding, checking if we need certain properties like scheduled delivery
- Avoid creating some unnecessary SimpleString instances
- Removed some intermediate ActiveMQBuffer allocation
- Removed some intermediate UnreleasableByteBuf allocation
Second attempt to fix the following compiler warning that is reported in Travis builds, this time using the correct cast type `Class<?>[]` which prevents temporary object allocation because of var-args handling:
```java
/home/travis/build/apache/activemq-artemis/artemis-core-client/src/main/java/org/apache/activemq/artemis/core/protocol/core/impl/wireformat/FederationStreamConnectMessage.java:151: warning: non-varargs call of varargs method with inexact argument type for last parameter;
return (FederationPolicy) Class.forName(clazz).getConstructor(null).newInstance();
cast to Class<?> for a varargs call
cast to Class<?>[] for a non-varargs call and to suppress this warning
```
This fixes the following compiler warning that is reported in Travis builds:
```
/home/travis/build/apache/activemq-artemis/artemis-core-client/src/main/java/org/apache/activemq/artemis/core/protocol/core/impl/wireformat/FederationStreamConnectMessage.java:151: warning: non-varargs call of varargs method with inexact argument type for last parameter;

```
When AMQPMessages are redistributed from one node to
another, the internal property of message is not
cleaned up and this causes a message to be routed
to a same queue more than once, causing duplicated
messages.
This commit introduces the ability to configure a downstream connection
for federation. This works by sending information to the remote broker
and that broker will parse the message and create a new upstream back
to the original broker.
A new feature to preserve messages sent to an address for queues that will be
created on the address in the future. This is essentially equivalent to the
"retroactive consumer" feature from 5.x. However, it's implemented in a way
that fits with the address model of Artemis.
The parameter failoverOnInitialConnection wouldn't seem to be used and
makes no sense any more, because the connectors are retried in a loop.
So someone can just add the backup in the initial connection.
When CoreMessage is doing copyHeadersAndProperties() it doesn't
make a full copy of its properties (a TypedProperties object).
It will cause problem when multiple threads/parties are modifying the
properties of the copied messages from the same message.
This will be particular bad if the message is a large message
where moveHeadersAndProperties is being used.
After a node is scaled down to a target node, the sf queue in the
target node is not deleted.
Normally this is fine because may be reused when the scaled down
node is back up.
However in cloud environment many drainer pods can be created and
then shutdown in order to drain the messages to a live node (pod).
Each drainer pod will have a different node-id. Over time the sf
queues in the target broker node grows and those sf queues are
no longer reused.
Although use can use management API/console to manually delete
them, it would be nice to have an option to automatically delete
those sf queue/address resources after scale down.
In this PR it added a boolean configuration parameter called
cleanup-sf-queue to scale down policy so that if the parameter
is "true" the broker will send a message to the
target broker signalling that the SF queue is no longer
needed and should be deleted.
If the parameter is not defined (default) or is "false"
the scale down won't remove the sf queue.
* Upgrading versions
* Adding wildfly-common dependency as jboss-logmanager now depends on it
for simple common operations such as getting hostname or process id
* Updating bootclasspath with wildfly-common
Add tests
Add fix - if timeout occurs on sending packet, calls same code that is invoked if timeout occurs on during ping aligning logic, and ensuring JMS connection exception listener gets invoked to inform the client logic to react.
Historically the broker has read the XML configuration file as a String,
substituted system properties, and then parsed that String into an XML
document. However, this method won't substitute system properties in the
files which are imported via xinclude. In order to substitue system
properties in xincluded files the substitution needs to be performed
after the file is parsed into an XML document. This commit implements
that change and refactors the XMLUtil class a bit to eliminate redundant
code, obsolete comments, etc.
Implement using the ActiveMQ5 JMSXGroupFirstForConsumer, property as default, but make it possible for future to make it configurable easily. (Not this PR)
Add test
In adding auto-delete queue level feature, its been noticed as some feature bits were added during hot fix branch, that there's api break with the 2.6.x hotfix branch.
This addresses that by fixing this in 2.7.x

add javadoc
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.
Push isDirectDeliver method from netty impl, to the Connection interface
Add support to InVMConnection for isDirectDeliver flag and ability to set via config, defaulting to false, to keep current default behavior.
Extend DirectDeliverTest to check InVM as well.
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
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.
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
This helped decreasing a lot of pressure on GC by not creating
as many runnables for each write.
Besides this helps fixing some of the issues I would have had on refactoring AMQP
over flushing writes and other asynchronous issues.
Refactor ServerJMSMessage so it correctly transposes all JMSX headers.
Push common JMSX mappings for JMS to Message Interface mappings into MessageUtil to avoid duplication in ActiveMQMessage and ServerJMSMessage
Add test cases
Add GroupSequence to Message Interface
Implement Support closing/reset group in queue impl
Update Documentation (copy from activemq5)
Change/Fix OpenWireMessageConverter to use default of 0 if not set, for OpenWire as per documentation http://activemq.apache.org/activemq-message-properties.html
A synchronization block was missed during the AMQP refactoring.
This could impact use-cases involving diverts, cluster bridges, and
multiple concurrent consumers.
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
Given that NettyConnector::createConnection isn't happening on the
channel's event loop, it could race with a channel close event, that
would clean the whole channel pipeline, leading to a NPE while
trying to use a configured channel handler of the pipeline.
Extend test case to reproduce problem of client created queues being incorrectly removed on simple reload of config.
Add a flag/field to the queues created by configuration/broker.xml so we can correctly filter only queues created/managed by config.
Update listConfiguredQueues to use the new queue flag
Add Tests
Add implementation inline with other queue updatable settings.
Enhance tests to ensure queue is not destroyed during config change and messages in queue already are preserved
First, QueueQuery should use address name for address settings
The name used for looking up address settings for a queue now uses the
address name if there is a local queue binding
Second, make sure sent credits to the server is the correct value
In some cases users who migrate from 1.x to 2.x may still want to keep
the legacy prefixes for their JMS destinations (i.e. "jms.queue.",
"jms.topic.", etc.). This commit adds a boolean on our ConnectionFactory
implementation so that it will use the old prefixes when invoking the
queue/topic creation methods on the Session implementation.
Fix checkstyle
Avoid duplicated logic
Ability to filter and group
Instantiate SimpleString property key once
Get property value via getObjectProprty to ensure all special mapped properties such as in AMQPMessage would return
Avoid a custom string to represent null, instead rely on Java's representation "null" by using Objects.toString to get the string value of the property value used to group by.
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.
In a live-backup scenario, if the live is restarted and shutdown too soon,
the client have a chance to fail on failover because it's internal topology
is inconsistent with the final status. The client keeps connecting to live
already shut down, never trying to connect to the backup.
It's a porting from HORNETQ-1572.
- Split protocols into individual chapters
- Reorganize summary to flow more logically
- Fill in missing parameters in configuration index
- Normalize spaces for ordered and unordered lists
- Re-wrap lots of text for readability
- Fix incorrect XML snippets
- Normalize table formatting
- Improve internal links with anchors
- Update content to reflect new address model
- Resized architecture images to avoid excessive white-space
- Update some JavaDoc
- Update some schema elements
- Disambiguate AIO & ASYNCIO where necessary
- Use URIs instead of Objects in code examples
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.
Added an example to demonstrate how to configure and use openssl
Moved/Added netty-tcnative dependency to artemis-distribution
Changed artemis-jms-client-all pom to exclude io.netty from relocation
so that the native openssl can be loaded
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
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.
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
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).
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.
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.
- 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
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.
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.
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
HornetQClientProtocolManager is used to connect HornteQ servers.
During reconnect, it sends a CheckFailoverMessage packet to the
server as part of reconnection. This packet is not supported by
HornetQ server (existing release), so it will break the backward
compatibility.
Also fixed a failover issue where a hornetq NettyConnector's
ConnectorFactory is serialized to the clients who cannot
instantiate it because class not found exception.
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.
Change all use from Set<RoutingType> to EnumSet<RoutingType>
Deprecating any old exposed interfaces but keeping for back compatibility.
Address info to avoid iterator on getRoutingType hotpath, like wise can be avoided where single RoutingType is passed in.
* 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.
Expose User associated with creating Queue on JMX QueueControl (as attribute)
Allow setting of the user to associate with creating the queue when configured in broker.xml (before only if created over wire is it possible to set the user)
Revert "ARTEMIS-1545 Adding HornetQ 2.4.7 on the mesh to validate send-acks"
I'm reverting this as the testsuite is broken..
We will send it back once worked out.
This reverts commit 8f5b7a1e73.
This reverts commit 9b982b3e30.
add connection ID to the trace logging output
dealing with reading/writing packets. This helps correlate
the packets read/written to an individual tcp connection
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.
The temporary deadlock is avoided by removing 'synchronized' from
ClientSessionImpl::getCredits method. As the method uses only
a producerCreditManger, only this object is guarded against
the parallel access.
When the execution of code jumps out of the while cycle,
it should check whether the blocking-call-timeout expired or not.
If no, ActiveMQUnBlockedException should be thrown
instead of ActiveMQConnectionTimedOutException.
The changes to remove netty-all removes the classifiers that add the
dependency to the netty transport that includes the compiled native
library wrapper. Add those classifiers back in.
Added a new trustAll flag which will support trusting any client
keystore when doing testing against a broker. This setting should not
be used in production and is strictly for testing.
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.
Update Tranformer to be able to handle initiation via propertiers (map<string, string>)
Update Configuration to have more specific transfromer configuration type, and to take properties.
Support back compatibility.
Add AddHeadersTransformer which is a main use case, and can act as example also.
Update Control's to expose new property configuration
Add test cases
Update examples for new transformer config style
- it is now possible to disable the TimedBuffer
- this is increasing the default on libaio maxAIO to 4k
- The Auto Tuning on the journal will use asynchronous writes to simulate what would happen on faster disks
- If you set datasync=false on the CLI, the system will suggest mapped and disable the buffer timeout
This closes#1436
This commit superseeds #1436 since it's now disabling the timed buffer through the CLI
priority is stored as a byte in the ICoreMessage's map.
It is stored then in a int when it is converted to JMS (as JMSPriority
header is an Integer).
JIRA: https://issues.apache.org/jira/browse/ARTEMIS-1448
add the adaptTransportConfiguration() method to the
ClientProtocolManagerFactory so that transport configurations used by
the ClientProtocolManager have an opportunity to adapt their transport
configuration.
This allows the HornetQClientProtocolManagerFactory to adapt the
transport configuration received by remote HornetQ broker to replace the
HornetQ-based NettyConnectorFactory by the Artemis-based one.
JIRA: https://issues.apache.org/jira/browse/ARTEMIS-1431
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
When calling a consumer to receive message with a timeout
(receive(long timeout), if the consumer's buffer is empty, it sends
a 'forced delivery' the waiting forever, expecting the server to
send back a 'forced delivery" message if the queue is empty.
If the connection is disconnected as the arrived 'forced
delivery' message is corrupted, this 'forced delivery' message
never gets to consumer. After the session is reconnected,
the consumer never knows that and stays waiting.
To fix that we can send a 'forced delivery' to server right
after the session is reconnected.
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.
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
Core client with netty connector and acceptor doing kerberos
jaas.doAs around sslengine init such that the SSL handshake can do kerberos ticket
generaton and validation.
The kerberos authenticated user is then validated with the security manager before
being populated into the message userId.
The feature is enabled with the kerb5Config property. When lowercase it is the
principal. With a leading uppercase char it is the login.config entry to use.
The default id-cache-size is 20000 and the default
confirmation-window-size is 1MB. It turns out the 1MB
size is too small for id-cache-size.
To fix it we adjust the confirmation-window-size to 10MB. Also
a test is added to guarantee it won't break this rule when this
default value is to be changed to any new value.
It fixes compatibility issues with JMS Core clients using the old address model, allowing the client to query JMS temporary queues too.
you would eventually see this issue when using older clients:
AMQ119019: Queue already exists
When a broken packet arrives at client side it causes decoding error.
Currently artemis doesn't handle it properly. It should catch such
errors and disconnect the underlying connection, logging a proper
warning message
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.
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.
Wrap the host added to the HTTP request headers with IPV6Util.encloseHost
to ensure that load balancers that reads the header will have a valid
IPv6 address.
JIRA: https://issues.apache.org/jira/browse/ARTEMIS-1043
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.
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
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
There are some operations in ActiveMQServerControl that don't have
@Parameter annotations. That will make clients like JBoss Jon failed
to invoke those operations.
Also in AddressControl there is a typo in sendMessage. The second
parameter's name should be 'type' not 'headers'.
When HTTP Upgrade is enabled, update Netty's pipeline only after the
HTTP Upgrade handshake is successful *and* the trailing
EMPTY_LAST_CONTENT is received.
Otherwise, this EMPTY_LAST_CONTENT is handled by
ActiveMQChannelHandler which is only expected to handle ByteBuf
JIRA: https://issues.apache.org/jira/browse/ARTEMIS-963
* Fix isEquivalent() method to take into account the activemqServerName
property when httpUpgradeEnabled is true. Two ActiveMQ server hosted on
the same app server may have the same host and port (corresponding to
the Web server HTTP port). The activemqServerName property is used to
distinguish them.
* Iron out HTTP upgrade handler so that the latch is always count down
and the channel context is closed unless the handshake was completed
successfully
