The package tangles is caused by the explicit classes declarations.
* Since we use only method definitions from those classes, there is just
enough to use class names and use reflection to get class objects and
then get methods from them
_The fix is fully compatible for back-porting_
**Cherry-pick to 5.0.x**
* Wrap non-`StandardIntegrationFlow` into Proxy
In previous version all the `IntegrationFlow` beans have been replaced
by the `StandardIntegrationFlow` i the `IntegrationFlowBeanPostProcessor`
if they are lambda.
That works for Java, but doesn't with Kotlin, since lambdas i last one
are not synthetic classes.
Therefore some Java DSL definitions (especially `.subFlowMapping()`)
don't work consistently in two languages.
* Introduce `IntegrationFlowLifecycleAdvice` to wrap all the
non-`StandardIntegrationFlow`s (excluding `IntegrationFlowAdapter`)
into the `Proxy` to expose `SmartLifecycle` and `getInputChannel()`
operations and delegate them to the internal `StandardIntegrationFlow`
created by the `IntegrationFlowBeanPostProcessor`.
* This way any custom `IntegrationFlow` implementations can be used
for manual flow registration via `IntegrationFlowContext`
* Polish `RouterDslTests.kt` for the `@Bean`s for sub-flows.
* Document in the `dsl.adoc` a request-reply approach for the case
when `.subFlowMapping()` refers to an `IntegrationFlow` `@Bean`.
* Polishing for the `FlowServiceTests` since all the
non-`StandardIntegrationFlow`s and not-`IntegrationFlowAdapter`s are
wrapped now to the Proxy.
* Add missing `from()` delegations into the `IntegrationFlowAdapter`
* Polishing for the `ManualFlowTests` since all the `IntegrationFlow`
now are `Lifecycle` after wrapping to the Proxy.
* Add JavaDocs to the IntegrationFlowLifecycleAdvice and polishing for the dsl.adoc
* * Add JavaDocs for the `IntegrationFlowBeanPostProcessor.processIntegrationFlowImpl()`
* Improve JavaDoc for the `RouterSpec.subFlowMapping()`
* Assert in the `FlowServiceTests` that proxied custom flow implements
all the expected interfaces

There is a one second delay before a socket close is propagated if there is an active
assembler. This is generally only a problem with deserializers that use EOF to signal
message end (such as the `ByteArrayElasticRawDeserializer`).
Attempt to insert an EOF marker into the buffer queue so that the `getNextBuffer()` will
exit immediately on `close()` if it is blocked awaiting a buffer.
**cherry-pick to 5.0.x, 4.3.x**
https://build.spring.io/browse/INT-SI50X-JOB1-56
We can't wait for the latch in the interruptable code flow;
we can't have a round-robing election guarantees.
* Add `Thread.sleep(LockRegistryLeaderInitiator.this.busyWaitMillis)`
to the `LockRegistryLeaderInitiator` when we restart the main task
* Remove latches waiting and thread shifting from the
`RedisLockRegistryLeaderInitiatorTests`
* Use long `busyWaitMillis` for yielding initiator to let the second
candidate to be elected
**Cherry-pick to 5.0.x**
https://build.spring.io/browse/INT-FATS5IC-501/
When we try to wait for the `Latch` in the interruptable code flow,
it is a fact that we step away from the waiting and end up with the
race condition downstream.
* Wrap `Latch` in the interruptable `publishOnRevoked()` code to the
`Executor.execute()`
* Remove `deleteTimeoutMillis` option from the `RedisLockRegistry`
since it doesn't make sense in the interruptable code.
* Add `RedisLockRegistry.setExecutor()` to allow to inject an external
`Executor`
* Add more debug logging into the `LockRegistryLeaderInitiator`
**Cherry-pick to 5.0.x**
https://build.spring.io/browse/INT-MASTER-1024
When the Lettuce Redis client catches an `InterruptedException`, it is
wrapped to the `RedisCommandInterruptedException`, therefore when we
catch an exception on our code level it is not an `InterruptedException`
anymore and we can't proceed in the loop because the tread is
`interrupted` already.
* Check the `interrupted` alongside with the `InterruptedException`
to restart a loop from a fresh thread.
**Cherry-pick to 5.0.x**
JIRA: https://jira.spring.io/browse/INT-4462
When the HTTP request body is empty, the `HttpMessageReader` ends up
with the empty `Mono` which can't be evaluated to any reasonable value.
* Add fallback to `requestParams` when `Mono` for body is empty and
also when `payloadExpression` returns null
**Cherry-pick to 5.0.x**
JIRA: https://jira.spring.io/browse/INT-4463
Certain options, such as `maxInFlight` were not exposed.
Deprecate the setters on the factory and allow the user to inject a pre-configured
`MqttConnectOptions`, thus making all (and any new) properties available to be
configured.
JIRA: https://jira.spring.io/browse/INT-4464
A `ZookeeperMetadataStore.get()` is based on the `this.cache` variable.
This one is initialized in the `start()`.
* Assert `isRunning()` in the `get()` before using.
**Cherry-pick to 5.0.x and 4.3.x**
* Use Lettuce Redis client; Redis module fixes
The Lettuce client is based on the Netty and more stable, than Jedis
therefore we get a performance improvement for tests
(it saves us at about 30 seconds).
Also this client doesn't fail for me on Windows sporadically (very often)
with the `ConnectionClosedException`
* After switching to the Netty-based client, we expose the interrupted
Thread issue in the `LockRegistryLeaderInitiator`.
If we interrupted (expected behavior), we try to unlock calling
`RedisLockRegistry`, but Netty client reject our request because the
thread is interrupted, therefore we never delete the lock when we yield
our leadership.
Fix the issue with shifting a `RedisTemplate.delete()` operation to the
`ExecutorService` when the current thread is interrupted
* Allow to configure such an `ExecutorService` and timeout to wait for
the `submit()` result
* Refactor `RedisAvailableRule` and all the Redis tests do not expose
the target `RedisConnectionFactory` implementation.
* Make all the test-cases based on the `connectionFactory` created by
the `RedisAvailableTests.setupConnectionFactory()`
* Tweak some unnecessary timeouts and sleeps for better tests task
throughput
* Add a `Log4j2LevelAdjuster` into the `RedisLockRegistryLeaderInitiatorTests`
https://build.spring.io/browse/INT-FATS5IC-497
Fixes `JdbcMessageStoreTests` sporadic failure where there is no
guarantee that message are going to be polled from the group the same
order they've been inserted
Cherry-pick to `5.0.x`
https://build.spring.io/browse/INT-MASTER-1017
Looks like non-`volatile` `size` property in the `LinkedList` is not
updated properly for the `contains()` assertion, therefore we end up
with the `ConcurrentModificationException`
* Move `assertThat()` into the `synchronized (overridePresent)` block
to enforce CPU cache flushing and, therefore, have an actual value
for the `LinkedList.size` during iteration
JIRA: https://jira.spring.io/browse/INT-4461
Convert `byte[]` to `String` using `URF-8` by default.
Add optional evaluate methods to JsonPathUtils with a Charset to use when
converting `byte[]` to `String`.
This is not currently exposed using SpEL. It can be done, but probably not worth
the effort until somebody asks for it.
**cherry-pick to 5.0.x, 4.3.x**
* Use `BAIS`
For better back-pressure handling do not perform active operations
directly on the current `Flux` (e.g. via `doOnNext()`).
It's better to postpone such a handling to back-pressure ready operators
Like in this `FluxMessageChannel` case, the `.handle()` operator is
wrapping the "hard" `send()` operation.
Also include `.errorStrategyContinue()` do not stop during message
processing
* INT-4458: Do not expose recursive generics API
JIRA: https://jira.spring.io/browse/INT-4458
According Kotlin generics system restrictions we can't expose API
based on the recursive generics, like we have with Java DSL for JMS
* Replace explicit recursive generics on factory method with the wildcard (`?`).
This way both Kotlin and Java are able to instantiate target object and perform
the proper chain API auto-completion
* Fix `JmsInboundChannelAdapterSpec` to deal with provided `S` type for the
`configureListenerContainer()` - the way we can configure a `JmsDefaultListenerContainerSpec`
* Add `kotlin-spring` Gradle plugin to avoid extra `open` modificator on `@Bean` methods
* Add `JmsDslKotlinTests.kt`
**Cherry-pick to 5.0.x excluding Kotlin support**
* Fix `Amqp` DSL factory for recursive generics
* Polishing for Kotlin tests
We don't change JDBC scripts too often and even if we do that, it's not
so hard to copy/paste the script throughout all the supported platforms
instead of rely on the pretty old VPP tool and suffer from performance
degradation during regular day-to-day development.
Plus there is some bug in the VPP when it generates a script for the
Derby, so we end up with erroneous braces in the sentence:
```
MESSAGE_SEQUENCE BIGINT NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1),
```
I have to remove them manually each time I switch between Gradle versions
JIRA: https://jira.spring.io/browse/INT-4456
Since Kotlin compiles lambdas different way than Java, they are not
synthetic classes at runtime anymore.
Therefore we fallback to the method invocation logic, but since Java 8
interfaces has `default` methods as well the `MessagingMethodInvokerHelper`
can't select the target method for invocation
* Use explicit `Function.apply()` for non-synthetic implementations
* Add `RouterDslTests` Kotlin-based test-case
**Cherry-pick to 5.0.x**
* Add more explicit methods for invokers
The `transactionWithCommitAndAdvices()` uses `SimpleRepeatAdvice`
which essentially performs `doPoll()` twice.
In this case we don't have enough messages in the `goodInputWithAdvice`
queue
* Add one more message to the `goodInputWithAdvice` queue during testing
* Increase all the timeouts
* Increase capacity in queues for the `transactionWithCommitAndAdvices()`
**Cherry-pick to 5.0.x and 4.3.x**
JIRA: https://jira.spring.io/browse/INT-4351
The `WatchService` reacts to the events in the file system and keep
track ove the events until we poll them, e.g. via `listEligibleFiles()`
in the `WatchServiceDirectoryScanner`.
On the other hand the `SourcePollingChannelAdapter` calls the mentioned
`listEligibleFiles()` according its polling period.
At this moment the `FileListFilter` is applied to the polled files.
It may happen that `LastModifiedFileListFilter` can't accept too young
files yet and they are lost for the future consideration.
* To allow, for example, to retain young files by the
`LastModifiedFileListFilter` judgment for the future cycles add
`DiscardAwareFileListFilter` with the `DiscardCallback` support.
The `WatchServiceDirectoryScanner` now registers such a callback into
the filter and stores discarded files into the `filesToPoll` queue
for the future poll cycle.
**Cherry-pick to 5.0**
Fix compilation warnings
* Replace `DiscardCallback` with the plain `Consumer`
* Ensure uniqueness in the `WatchServiceDirectoryScanner` internal
queue via a `Set` implementation, since discard callback may be called
several times for the same file from the `CompositeFileListFilter`
according to its nature
* Add JavaDocs and Docs
Change `@since` to `5.0.5`

When using java config, `setChannelMapping` NPEs due to no AC.
**cherry-pick to 4.3.x, and to master, removing AC check**
* Polishing - PR comment
* Resolve TODO in the `ErrorMessageExceptionTypeRouter`
Looks like Derby is much slower than H2, plus it doesn't look so stable
having so much sporadic failures.
Looks like moving to H2 here saves for us `500 ms` test working time
**Cherry-pick to 5.0.x**
* Upgrade to Gradle 4.7 and others, polishing build
* Fix `MqttAdapterTests` according requirement of the latest Mockito
* Move `int-derby.properties` to the `/resources` from `/java`
* Fix Checkstyle violations
The message in the `QueueChannel` appears for consuming a bit earlier
than TX is committed
* Introduce `afterCommitLatch` into the test verify the state
when TX is really committed and data is removed from DB
**Cherry-pick to 5.0.x and 4.3.x**
Looks like we have started to fail much often
since upgrade to the `Derby-10.14.1.0`:
cb0d43db6b
That is also related to this https://jira.spring.io/browse/INT-4445
* Remove all the `drop` mentioning for Derby scripts -
it just doesn't support `IF EXISTS`.
More over we don't need to worry about drops since each test now starts
its own fresh embedded DB
**Cherry-pick to 5.0.x**
* INT-4446 Improve EmbeddedJsonHeadersMessageMapper
JIRA: https://jira.spring.io/browse/INT-4446
* Do not recreate message if not necessarily
* Do not let to generate `id` and `timestamp` if they are not mapped
* Use `smartMatch` to allow to configure negative patterns
* Introduce `PatternMatchUtils.smartMatchIgnoreCase()` for convenience
**Cherry-pick to 5.0.x**
* * Polishing `EmbeddedJsonHeadersMessageMapper`
JIRA: https://jira.spring.io/browse/INT-4447
When we get an exception during `this.lock.unlock()`, we don't revoke
leadership.
In case of external resource (e.g. JDBC) this may cause a race condition
when the second candidate is selected as leader when connection comes back
* Catch `this.lock.unlock()` exceptions and log them under DEBUG.
This way we proceed to the `handleRevoked()` logic
**Cherry-pick to 5.0.x and 4.3.x**
https://build.spring.io/browse/INT-MASTER-999/
Since `BeanFactoryTypeConverterTests` and `CallerBlocksPolicyTests`
uses too long `Thread.sleep()` there is no guarantee that they are going
to be performed after expected 10 seconds
* Decrease `Thread.sleep()` in those tests
* Increase timeouts in the `RoundRobinDispatcherConcurrentTests` and
`ManualFlowTests`
* Fix `PollerAdviceTests` to re-use `TaskScheduler` from the ctx
instead of local, not closed instance
* Use `OnlyOnceTrigger` instead of local implementations
* Change the `primary` `Trigger` bean to the `PeriodicTrigger` as well.
The minimum interval for the `CronTrigger` is 1 seconds - it doesn't
matter for this test-case
JIRA: https://jira.spring.io/browse/INT-4445
Looks like `/dataSource` temporary directory is busy in between different
tests.
The thought is like a high-frequently polling endpoint keeps DB resource
from removing.
* Explicitly `stop()` endpoint in the `JdbcMessageStoreChannelTests`
* Optimize
`JdbcMessageStoreChannelTests.testSendAndActivateTransactionalSend()`
to rely on the short `1` millisecond TX timeout.
This safes for us 10 seconds of the tests executions.
* Configure all the embedded DB beans for the `ignore-failures="ALL"`
as a fallback option if polling endpoint is not a cause of the concurrent
resource access.
**Cherry-pick to 5.0.x**
JIRA: https://jira.spring.io/browse/INT-4438
The `SmartLifecycleRoleController` is based on the `MultiValueMap`
which used internally a `List` for the values.
With such an architecture we can add the same value several times.
On the other hand we are iterating over `Lifecycle`s in the role and
build a `Map` for their running status.
In this case when `NamesComponent`s return the same name the Java
`Collectors.toMap()` fails with a duplicate key error.
In any cases it would be better do not allow to add the same lifecylce
several time to the role or different with the same name.
* Add search logic to the `addLifecycleToRole()` to fail fast with the
`IllegalArgumentException` because a lifecycle with the same name is
already present in the role
**Cherry-pick to 5.0.x**
* Remove redundant `this.initialized = false` from the
`AbstractPollingEndpoint.doStop()`
Add `allEndpointsRunning()` verification to the `EndpointRoleParserTests`
Polishing
https://build.spring.io/browse/INT-SI50X-20
Looks like 5 seconds is not enough to wait for the test completion,
especially on CI server
* Refactor `PollingConsumerEndpointTests` to use `OnlyOnceTrigger`
from the test-support module instead of local `Trigger` implementation
* Increase timeout for latch in the `OnlyOnceTrigger` to 10 seconds
**Cherry-pick to 5.0.x**
https://build.spring.io/browse/INTSAMPLES-NIGHTLY-2413
When we fail with the
`java.net.BindException: Address already in use (Bind failed)` in the
`TcpNetServerConnectionFactory.run()`, the `serverSocket` property
remains `null` and we get `NPE` in the `catch` block trying to `close()`
the socket.
* Call `stop()` instead which has all the required protections.
**Cherry-pick to 5.0.x and 4.3.x**
https://build.spring.io/browse/INT-FATS5IC-457
The H2 `1.4.197` has fixed some issues
(in particular https://github.com/h2database/h2database/issues/178)
and introduced some breaking changes for us, although they are
reasonably good.
* Fix `JdbcOutboundGatewayParserTests` to use correct identifiers
for returned generated keys instead of previously used `SCOPE_IDENTITY()`
**Cherry-pick to 5.0.x and 4.3.x**
https://build.spring.io/browse/INT-AT42SIO-820/
The test configs use `fixed-rate="100"`.
This way when Inbound Channel Adapter is declared earlier in the
config than `<jdbc:embedded-database>`, there is a chance that we start
to poll DB before it is really initialized.
* Reorder config so embedded DB is initialized before an
Inbound Channel Adapter
**Cherry-pick to 5.0.x, 4.3.x and 4.2.x**
JIRA: https://jira.spring.io/browse/INT-4440
The previous fix eliminated an extra `generateId()` call, but at the
same introduced regression do not populate `id` and `timestamp` from
the serialized state, e.g. after JSON transferring over the network
* Introduce a couple utility methods in the `MutableMessageHeaders`
to extract and parse `id` and `timestamp` from the provided headers
**Cherry-pick to 5.0.x**
