* Re enabling Java tests in akka-docs (they were not run before)
* Fixed bug #19764
* #19735 Rewrote every sample using the deprecated PushPullStage and friends
using GraphStage
* Pruned old unused graph images
* Added missing graffle file for new graph images
* Sink.seq (Scala DSL) now returns immutable.Seq rather than Seq
* Sink.seq will not silently truncate when incoming elements is > Int.MAX_VALUE
* minor doc fixes
* replacing various grouped(n) / Sink.head with limit(n) / Sink.seq in various tests
* fix inconsistent indentation in RequestParserSpec
Also dealing with merge conflicts from my fork's head
Conflicts:
akka-http-core/src/test/scala/akka/http/impl/engine/parsing/HttpHeaderParserSpec.scala
akka-http-core/src/test/scala/akka/http/impl/model/parser/HttpHeaderSpec.scala
This entails:
* adding akka.pattern.PatternCS.* to enable ask etc. with
CompletionStage
* changing RequestContext to offer an ExecutionContextExecutor for the
CompletionStage.*Async combinators
* splitting up akka.stream.Queue for JavaDSL consistency
Any previous usage can be represented in this fashion while typically
saving one function allocation and also saving the function literal’s
syntax overhead (for the seed). Plus a new feature: the provided
iterator does not have to be infinite, limiting how far expand is
allowed to go.
* The old implementation would cap the pool size (both corePoolSize
and maximumPoolSize) to max-pool-size, which is very confusing
becuase maximumPoolSize is only used when the task queue is bounded.
* That resulted in configuring core-pool-size-min and core-pool-size-max
was not enough, because it could be capped by the default max-pool-size.
* The new behavior is simply that maximumPoolSize is adjusted to not be
less than corePoolSize, but otherwise the config properties match the
underlying ThreadPoolExecutor implementation.
* Added a convenience fixed-pool-size property.
* make the standard queries "single method interfaces" that may be implemented
by a query journal plugin
* remove hints (major problems with varargs anyway), the hints for standard
queries should be given in configuration instead, e.g. refresh-interval
* clarify how to enable the plugin
* added empty class property in fallback config in reference
to have a proper place to document that and throw a more
specific exception if it is not defined
* also some formatting of reference.conf
