+ with javadsl
+ allows configuring log levels
+ allows turning off logging of certain actions completely
+ cookbook adjusted to show this instead of manual PushStage
- PENDING: preStart based impl will be faster, coming soon
* Remove optional attributes parameter in favor of withAttributes
* Overload explosion when trying to add attributes to ZipWith.
* Aligned with Flow and Source.
`abstract class FlattenStrategy` was used in both javadsl and scaladsl, but the concrete concat
for the javadsl was in javadsl.FlattenStrategy and the concrete concat for the scaladsl is in
stream.FlattenStrategy.
Now there are separate FlattenStategy in scaladsl and javadsl packages and conversion
as we have in other places.
* replace JavaConverters with explicit methods
* remove asJava/asScala for FlattenStrategy
* Remove name parameter (no overloads), naming is performed using `.withAttributes` or the new
convenience `.named`. Those adds the OperationAttribute.Name and also change the name of the
shape Inlet and Outlet.
* Remove Source/Sink parameter list for 0 parameter methods,
this allows usage of `Sink.head` instead of `Sink.head()`
Changed rules:
* 1.9 Always onSubscribe prior to any other signals
* 1.9 NullPointerException if subscriber is null
* 3.17 Long overflow, effectively unbounded instead of onError
Fixed some more things:
* fixed some FIXME
* Long drop and take
* memory leaks in tck tests, use BeforeClass to create ActorSystem
use AfterClass to shutdown ActorSystem
* more tck tests
* don't emit OnComplete when substream is cancelled
* work around for memory leak in PrefixAndTail
* add supervion for stages and built in ops run by interpreter
* add supervision for mapAsync and mapAsyncUnordered
* add supervision to groupBy and splitWhen
* reference doc for scala and java
* StreamTcp and Http extensions now return Flows and Sources that can be materialized later
* Flow can now be completed with another flow to be turned into a runnable flow
* replace all existing Transformer with Stage (PushPullStage)
* use Flow[ByteString, ByteString] as encoder/decoder transformer in http
* use the IteratorInterpreter for strict if possible
* emit then become
* emit then finish
* termination emits
* FlowTransformerSpec
* rework types to work with Java API
* rename and move things
* add scaladoc
