* case object and case class for MixMetricsSelector
* Rename decay-half-life-duration to moving-average-half-life
* Clarification of decay-half-life-duration and collect-interval
* Removed Fields, Java compatibility issue
* Adapt for-yield variables
* Comment metrics collector constructor that takes system param
* Don't copy EWMA if not needed
* LogOf2 constant 0.69315
* Don't use mapValues
* Remove RichInt conversion
* sigar version replace tag in docs
* createDeployer factory method to make it possible to override
deployer in subclass
* Improve readability of MetricsListener (in sample)
* Better startup of factorial sample (no sleep)
* Many minor enhancements and cleanups
- PropertyMaster is the only place in Akka which calls
ClassLoader.getClass (apart from kernel, which might be special)
- all PropertyMaster methods (there are only three) take a ClassManifest
of what is to be constructed, and they verify that the obtained object
is actually compatible with the required type
Other stuff:
- noticed that I had forgotten to change to ExtendedActorSystem when
constructing Extensions by ExtensionKey (damn you, reflection!)
- moved Serializer.currentSystem into JavaSerializer, because that’s the
only one needing it (it’s only used in readResolve() methods)
- Serializers are constructed now with one-arg constructor taking
ExtendedActorSystem (if that exists, otherwise no-arg as before), to
allow JavaSerializer to do its magic; possibly necessary for others as
well
- Removed all Option[ClassLoader] signatures
- made it so that the ActorSystem will try context class loader, then
the class loader which loaded the class actually calling into
ActorSystem.apply, then the loader which loaded ActorSystemImpl
- for the second of the above I added a (reflectively accessed hopefully
safe) facility for getting caller Class[_] objects by using
sun.reflect.Reflection; this is optional an defaults to None, e.g. on
Android, which means that getting the caller’s classloader is done on
a best effort basis (there’s nothing we can do because a StackTrace
does not contain actual Class[_] objects).
- refactored DurableMailbox to contain the owner val and use that
instead of declaring that in all subclasses
- when encountering new message type, check all bindings which map apply
- if multiple are found, choose the most specific one if that exists or
verify that all mappings yield the same serializer
- in case of remaining ambiguity, throw exception
- also add special handling for “none” serializer mapping: turn off a
default
- move all creation of ActorRefs into the ActorRefProvider (deadLetters,
locker)
- rootPath does not contain remote transport address any longer in order
to start the LocalActorRefProvider before the RemoteTransport; the
transport address is inserted during serialization only, which enables
us later to have more than one transport available for one actor
system (maybe even needed for clustering)
- fix inheritance between DeadLetterActorRef and EmptyLocalActorRef
- document some start-up dependencies by reordering constructor code
- fix remote tests which used self.path for identifying remote actors
(since that no longer includes the remote transport address)
- add provider, guardian, systemGuardian and deathWatch to it
- make ActorSystemImpl extend ExtendedActorSystem
- use ExtendedActorSystem for creating extensions, thereby limiting the
access extensions get to just those four published methods.
* Config lib 4f3a91f
* All reference files named reference.conf, all will be loaded
* Usage of ConfigFactor.load as default way
* Extensions use same config as ActorSystem.settings.config
* Split config reference to one for each module/extension.
* Adjusted signature of registerExtension to avoid race of extension init
* Moved Duration.dilated to testkit
* TestKitExtension
* RemoteExtension
* SerializationExtension
* Durable mailboxes extensions
* Fixed broken serialization bindings and added test
* Updated configuration documentation
* System properties akka.remote.hostname akka.remote.port replaced with akka.remote.server.hostname and akka.remote.server.port
* Adjustments of ActorSystem initialization. Still don't like the two-phase constructor/init flow. Very fragile for changes.
