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.
- Avoid blowing up on string bodies of any size if the valueSizeLimit bits are configured to disable limit
- Dont NPE if amqp-value + binary body is sent without a content-type, as it always should be.
- Include expected prefix when adding delivery delay and ingress time annotations.
- Use the actual name for ingress time annotation, as with all other annotations.
- Use correct object type when testing equality with content-type value.
- Use consistent case for 'groupId' in different properties.
The test I wrote for ARTEMIS-3513 is throwing a few convert exceptions
because of SimpleString versus String conversion
This commit is addressing the issue,
The previous commit (the one addressing ARTEMIS-3513) should provide the test for this change.
While converting a core message to an OpenWire message there may be an
error processing a property value. Currently this results in an
exception and the message is not dispatched to the client. The broker
eventually attempts to redeliver this message resulting in the same
error. Instead of throwing an exception the broker should simply log a
WARN message and skip the property. This will allow clients to receive
the message without the problematic property and the broker will not
have to attempt to redeliver the message again.
As a follow-up to #3618/dc7de893747b90b627d729f9f18a758bb4dad9d5 update
checkstyle to the latest version, restoring the originally intended
"RightCurly" style, and updating all the code to properly adhere to the
style as enforced by the new checkstyle version.
The version of checkstyle we used before the aforementioned commit had
a bug which didn't properly enforced our intended "RightCurly" style
(see https://github.com/checkstyle/checkstyle/issues/6345). That commit
changed the style to accommodate the handful of unintended style
violations. This commit reverts that change for 2 main reasons:
- The style was always intended to use `alone` for both `METHOD_DEF`
and `CTOR_DEF`.
- There are over 1,000 existing uses of the intended style and around
30 violations of this style which were unintentionally allowed.
Reverting the style back to the original and cleaning up the unintented
violations makes the code more consistent and prevents further style
inconsistencies in the future.
There were a handful of other changes related to checkstyle bugs which
allowed unintended style violations. These were related to indentation
levels.
This closes#3619
(with some minor changes from Robbie to fix remaining violations)
