- ActorProcessor terminated eagerly when ConcatAll had just taken up a
new input stream but not yet received onSubscribe for it
- The ActorProcessor eagerly shuts itself down upon onError and that
cannot be changed without completely reworking the Pump, so I opted
for just tracking the outstanding substreamSubscribers that have not
yet seen OnSubscribe and making them cancel properly when that arrives
(possibly later).
- create a fully RS compliant minimal identity processor (that is not an
Actor)
- replace SubscriberSourceVirtualProcessor,
PublisherSinkVirtualSubscriber and PublisherSinkVirtualPublisher with
this
- add tests that transform Sink.publisher’s and Source.subscriber’s
materialized value
- also remove the Keep.{left, right} optimization in order to make
side-effecting mat value transforms execute even if their values are
discarded
+ 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
- this also discovered two omissions in the Transfer infrastructure:
- inputsAvailableFor should be completed when the input is cancelled
- demandAvailableFor should be completed when the output is errored
also switch off tracing for SslTls—we don’t want this on in production
* found one bug of too early actor stop and thereby missing cancel of upstream,
in fan-in tests ""work with one immediately failed and one nonempty publisher"
These are synchronous implementations, because we need to be Java 6
compatible while developing on 2.3.x. However asynchronous
implementations using AsynchronousFileChannel will come soon for JDK7
users.
+ ActorPublisher/Subscriber now manage stopping of the actor
+ added documentation on configuring dispatcher for File IO
+ properly handle if source file does not exist
+ file sink / source come with default io dispatcher
> verified no actors are leaking
> exceptions are caught and onErrored properly
+ moved files to akka.stream.io
+ Added OutputStreamSink and InputStreamSource
The problem was reproduced with the TCK PrefixAndTailTest
required_spec313_cancelMustMakeThePublisherEventuallyDropAllReferencesToTheSubscriber
The tck subscriber was still referenced. Profiling revealed that the
root cause was the VirtualPublisher that holds a reference to the
realPublisher, which was MultiStreamOutputProcessor$SubstreamOutput,
which had the reference to the subscriber. The VirtualPublisher
is created by the Sink.publisher in the test, and the test holds
on to that VirtualPublisher reference.
The solution is to null out realPublisher field in the VirtualPublisher.
The old workaround with the NullSubscriber was removed.
Also made Sink.publisher reject additional subscribers.
* 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
* FlowMaterializer is now the actor independent interface
* ActorFlowMaterializer is the actor based interface
* MaterializerSettings renamed to ActorFlowMaterializerSettings
* impl.ActorBasedFlowMaterializer renamed to impl.ActorFlowMaterializerImpl
* Optimizations included in ActorFlowMaterializerSettings
* Note that http is using FlowMaterializer in api, but I suspect that it
will currently only run with a ActorFlowMaterializer
