This fills in the gaps for some missing parameters in the core bridge
documentation as well as fixes the example so it's actually valid
according to the XSD.
Currently when an MQTT topic filter contains characters from the
configured wildcard syntax the conversion to/from this syntax breaks.
For example, when using the default wildcard syntax if an MQTT topic
filter contains a . the conversion from the MQTT wildcard syntax to the
core wildcard syntax and back will result in the `.` being replaced with
a `/.`.
This commit fixes that plus a few other things...
- Implements proper conversions to/from one WildcardConfiguration to
another.
- Refactors the MQTT code which invokes these conversion methods. This
includes simplifying a lot of test code.
- Adds lots of tests for everything.
- Clarifies some variable naming to better distinguish between core and
MQTT.
- Move ActiveMQTestBase to artemis-test-support.
- Add reduced parent for current artemis-server tests.
- Add a simpler test case parent class unit tests can use.
- Convert some existing checks into a rule for reuse.
- Move various rules/utils to artemis[-unit]-test-support module from where they can be used instead of from artemis-server.
This commit:
- Eliminates MQTT session storage on every successful connection.
Instead data is only written when subsriptions are created or
destroyed.
- Adds a configuration property for the storage timeout.
- Updates the documentation with relevant information.
- Refactors a few bits of code to eliminate unnecessary variables, etc.
in cluster.
When we know that a node leaves a clustercleanly we shouldn't log WARN
messages about it.

Allows the configuration of AMQP Federation broker connections to be updated and
reloaded. This allows for update, add or remove of AMQP federation broker connections
as well as the basic AMQP sender and receiver broker connections. It checks for and
ignores changes in AMQP broker connections that are performing Mirroring as that
would lead to issues that can break mirroring.
I just did some static analysis of this code, and I believe it would be better to first add to the list
before setting the cancel task.
Reason for that is in case the Runnable is dequeued between the add in the deQueue and setting the cancel task.
Possibility is remote but my OCD wouldn't let me ignore this small possibility.
There is a race condition between ConnectionEntry.ttl and
FailureCheckAndFlushThread whereby an in-vm connection may get closed
inadvertently due to a TTL timeout. This is because ConnectionEntry.ttl
is initialized to 60000 and then later set to -1 upon the initial Ping.
If this update happens at *just* the right time in
FailureCheckAndFlushThread then the connection will be closed.
The fix ensures that the ConnectionEntry.ttl is set to -1 for in-vm
connections from the start. It also eliminates the possibility of the
race in FailureCheckAndFlushThread.
This fix is based on static analysis of the code. The timing window is
just too small to contruct a reliable test. The failure has only been
seen in the wild a handful of times.
When initially developed the expectation was that no more producers would keep connecting but in a scenario like this
the consumers could actually give up and things will just accumulate on the server.
We should cleanup these upon disconnect.
- Async commit
* async here meaning the recording of the commit record is not doing a sync on the storage.
This is useful for internal operations where we don't need an immediate sync on the journal storage.
- Wired notification
* I need finer control on a afterWired (to the storage) and before the completions, so I can plug the sync context on mirror right before the commit is called.
This commit does the following:
- Replaces non-inclusive terms (e.g. master, slave, etc.) in the
source, docs, & configuration.
- Supports previous configuration elements, but logs when old elements
are used.
- Provides migration documentation.
- Updates XSD with new config elements and simplifies by combining some
overlapping complexTypes.
- Removes ambiguous "live" language that's used with regard to high
availability.
- Standardizes use of "primary," "backup," "active," & "passive" as
nomenclature to describe both configuration & runtime state for high
availability.
This commit does the following:
- prevents a large stack trace when the user-supplied message filter
has errors
- improves feedback to user for filter-validity
- indents the search-field in the "Browse Queue" screen same as on
other screens
- fixes a spelling error in a nearby comment
As I worked through implementing a more generic JSON marshaller, I tried using reflection through BeanUtils and other ways
however the endresult was always worse as there were a few caveats that were not as easy to accomplish.
For that reason I went to a declarative appraoch where I define a meta-data object on AddressSettings and AddressSettingsInfo and
reuse the metadata in a few other places.
Allow for core messages to be tunneled over broker connection links used
for AMQP Federation and for broker mirroring. This eliminates the need to
convert from Core to AMQP and from loading core large messages fully into
memory for that conversion.
