It would be useful for security manager implementations to be able to
alter the client ID of MQTT connections.
This commit supports this functionality by moving the code which handles
the client ID *ahead* of the authentication code. There it sets the
client ID on the connection and thereafter any component (e.g. security
managers) which needs to inspect or modify it can do so on the
connection.
This commit also refactors the MQTT connection class to extend the
abstract connection class. This greatly simplifies the MQTT connection
class and will make it easier to maintain in the future.
Allow replication only certain addresses with mirror controller.
The configuration is similar to cluster address configuration.

The MQTT 5 (and 3.1.1) specification states:
Until it has received the corresponding PUBREL packet, the receiver
MUST acknowledge any subsequent PUBLISH packet with the same Packet
Identifier by sending a PUBREC. It MUST NOT cause duplicate messages to
be delivered to any onward recipients in this case [MQTT-4.3.3-10].
The broker prevents a duplicate message, but it doesn't respond with a
PUBREC. This commit fixes that.
Removing the connection ID property from the actual *message* breaks the
nolocal functionality. Removing the property isn't necessary in the
first place so this commit reomves that code.
Older versions of Openwire clients wil be affected by AMQ-6431.
As a result of the issue if the ID of the message>Integer.MAX_VALUE
a consumer configured with Failover and doing duplicate detection on the client
will not be able to process duplicate detection accordingly and miss messages.
This bug is causing tests in o.a.a.a.t.i.m.s.c.ConnectTestsWithSecurity
to fail.
This commit fixes the problem by setting the session's version earlier
in the logic handling the CONNECT packet so that the proper CONNACK
return code can be supplied to the remote client in case of
authentication failure.
The commit includes the following changes:
- Don't drop the connection on subscribe or publish authorization
failures for 3.1 clients.
- Don't drop the connection on subscribe authorization failures for
3.1.1 clients.
- Add configuration parameter to control behavior on publish
authorization failures for 3.1.1 clients (either disconnect or not).
Avoid storing the following values as byte[] for OpenWire:
- Marshalled properties. We already store the unmarshalled properties
so this is altogether redundant.
- Producer ID.
- Message ID.
- Various destination values.
Also, eliminate the "original transaction ID" conversion code as it's
never actually set from the incoming message.
MQTT 5 is an OASIS standard which debuted in March 2019. It boasts
numerous improvments over its predecessor (i.e. MQTT 3.1.1) which will
benefit users. These improvements are summarized in the specification
at:
https://docs.oasis-open.org/mqtt/mqtt/v5.0/os/mqtt-v5.0-os.html#_Toc3901293
The specification describes all the behavior necessary for a client or
server to conform. The spec is highlighted with special "normative"
conformance statements which distill the descriptions into concise
terms. The specification provides a helpful summary of all these
statements. See:
https://docs.oasis-open.org/mqtt/mqtt/v5.0/os/mqtt-v5.0-os.html#_Toc3901292
This commit implements all of the mandatory elements from the
specification and provides tests which are identified using the
corresponding normative conformance statement. All normative
conformance statements either have an explicit test or are noted in
comments with an explanation of why an explicit test doesn't exist. See
org.apache.activemq.artemis.tests.integration.mqtt5 for all those
details.
This commit also includes documentation about how to configure
everything related to the new MQTT 5 features.
