* INT-3045: Add `ZeroMqChannel` support
JIRA: https://jira.spring.io/browse/INT-3045
Provide a `SubscribableChannel` implementation for ZeroMQ
The general idea is to let to have a distributed channel implementation
where every client can connect to a single server backed by the channel.
The logic in the channel is fully transparent for end-user and there is just
enough to send message to it and subscribe for receiving on the other side.
If PUB/SUB model is used, all the subscribes (even over the network) going to
receive the same published message.
In case of PUSH/PULL only one subscriber in the whole cluster is going to get
the published message
* Use Reactor for better threading control
* JeroMQ is not interruptible-friendly: use control sockets to stop proxy loop
* Name Reactor's schedulers to avoid daemon threads
* * Use try-catch-with-resource to close sockets automatically
* Fix Checkstyle violations
* Use `Mono.handle()` to receive data from the socket
* * Optimize local for just a couple of PAIR sockets
* Implement TCP binding
* Add PUB/SUB tests
* * Fix subscriber scheduler name
* Optimize socket create logic
* Add PUSH/PULL over TCP test
* * Fix subscriber scheduler name
* Optimize socket create logic
* Add PUSH/PULL over TCP test
* Implement PUB/SUB over TCP
* * Introduce `ZeroMqProxy` - Spring-friendly component to configure and manage ZeroMq proxy
* Use this `ZeroMqProxy` logic as an external component for `ZeroMqChannel` testing
* * Fix Checkstyle
* Apply docs polishing
* Expose a capture socket on the proxy
* Implement `DisposableBean` in the `ZeroMqProxy` to destroy an internal executor service
* Add JavaDocs to `ZeroMqChannel`
* Add one more `ZeroMqChannel` to TCP test to be sure that proxy distribution works well
* * Add `hamcrest-core` dependency for Awatility
* * Add more JavaDocs to `ZeroMqProxy` and `ZeroMqChannel`
* Expose `ZeroMqChannel.setZeroMqProxy()` option for easier
configuration within the same application context
* Make `ZeroMqChannel` sockets configuration and connection
dependant on provided `ZeroMqProxy` (if any)
* Add `Consumer<ZMQ.Socket>` configuration callbacks to the `ZeroMqChannel`
* Expose `ZeroMqChannel.consumeDelay` option
* * Add docs for ZeroMQ
* Some additions into a `reactive-streams.adoc`
* Fix typo in the `xmpp.adoc`
* * Add `optional` `jackson-databind` since `ZeroMqChannel` uses it by default
* More words into docs
* * Fix language in docs according review
* Fix language in docs according review

* * Fix threading using a `publishOn()` for specific scheduler after `cache()`
* * Remove unused import
* * Change proxy port check from static `Mono.just()` to `Mono.fromCallable()`
to really evaluate the current port state on every repeat
* Add finite `100` repeat number to avoid infinite blocking when proxy is not started at all
* Add `doOnError()` for proxy `Mono` to log `ERROR` when repeat is exhausted
* * Fix Checkstyle violation

* Rework UPDATE logic according deprecations
* Use `ColumnMapRowMapper` for default `Map` payload type
* Clean up tests
* Enable `MessageChannelReactiveUtilsTests.testOverproducingWithSubscribableChannel()` back
* Disable `StompServerIntegrationTests` again since build on CI is stalled again
Resolves https://github.com/spring-projects/spring-integration/issues/3359
- replace removed simple counter with a `Timer`
- register DSL GPFB as beans so they can be discovered for wiring metrics
* Apply suggestions from code review
* Remove left over deprecation suppression
* Fix import
The `ReactorNettyTcpStompClient` is based on the `ReactorNettyTcpClient`
which uses a `Schedulers.newParallel()` which has to be shut downed in the end
* Migrate all the STOMP tests to JUnit 5
* Remove redundant `@SuppressWarnings("deprecation")`
* Add `Duration.ofSeconds(10)` to `StepVerifier.verify()`
to avoid infinite wait and lose failing text context on the hang CI build
Fixes https://github.com/spring-projects/spring-integration/issues/3226
* Implement a `ReactiveRedisStreamMessageProducer` to consume Redis streams
* Add support for consumer groups and group auto-creation
* Add `@author` to `RedisHeaders`
* Rename test methods in the `ReactiveRedisStreamMessageHandlerTests` to project code style
* Implement `hashCode()` & `equals()` for `Person` & `Address` testing models
* Fix `ReactiveRedisStreamMessageProducerTests` not creating bean for `ConnectionFactory`.
Otherwise it caused to create one more not controlled `RedisClient`
* Code style clean up in the `ReactiveRedisStreamMessageProducer`
* Implement a group creation logic as a reactive stream deferring the call until
a subscription happens on the final `messageFlux`
* Move a common code for message building as the last `map()` operator in the final `Flux`
* Remove an `IntegrationFlow` definition in the `ReactiveRedisStreamMessageProducerTests`
as redundant
- Simplify MBeans - instead of wrapping to expose lifecycle methods,
implement `ManageableLifecycle`. Register an additional MBean for
polled endpoints to control the lifecycle.
* Polishing
- Move `QueueChannel` `@ManagedAttribute`s to `QueueChannelOperations`
- Make all `AbstractEndpoints` `IntegrationManagedResource`s and remove `ManagedEndpoint`
to allow exposure of any `@Managed*` methods (including those on `Pausable`)
- Revert to `Lifecycle` for classes that are not related to endpoints
- Remove legacy metrics from docs
The `ArrayList` cannot be used in the test-case for checking
its size because the property is not `volatile`: even if
content of the list is what we expect (test logs confirms that),
the non-`volatile` property doesn't give us an actual value
* Use `CopyOnWriteArrayList` for this concurrent test to
be sure that internal `array.length` reflects the reality
after each interaction with the list
In preparation for https://github.com/spring-cloud/spring-cloud-stream-binder-rabbit/issues/303
Now that `CorrelationData` has a `Future<?>`, users might simply add
correlation data in a header and not receive confirm/return messages.
- No longer require channels for returns and confirms
- don't build the confirm message if there are no channels
- reduce the log level for no channels to DEBUG
- complete the user's future when a message is returned (async GW)
* Fix typo.
* Add gauges for queue channel size
The `QueueChannel` provides a current size and remaining capacity metrics
* Add Micrometer gauges into `QueueChannel` to expose the current values
of the size and remaining capacity
**Cherry-pick to 5.3.x, 5.2.x & 5.1.x**
* * Revert `@SuppressWarnings("unchecked")` for test
* Document new gauges for queue channel
* * Fix IntegrationManagementConfigurer for NPE on `metricsCaptor`
* Fix wording in meter descriptions

* Restore `Mono<RSocketRequester> getRSocketRequester()` on
`ClientRSocketConnector` and deprecate it in favor of newly introduced
`RSocketRequester getRequester()`: there is no need in wrapping a
`RSocketRequester` to deferred `Mono` since internal logic of the
`RSocketRequester` on client side is based on lazy-load API of the
`RSocketClient`
Since `RSocketRequester` is now lazy load on client side
there is no need to wrap it into a `Mono`.
* Change `getRSocketRequester()` to a plain getter
If there is a requirement to force connect to the server for receiving
requests from there, the `ClientRSocketConnector.connect()` should be used
