* 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.
The MonitorableThreadFactory.copy method does not take into account the
counter:AtomicLong field, which then always starts out at zero for every
new dispatcher; the PinnedDispatcher creates one dispatcher per actor,
hence resulting in identical thread names if used by multiple actors.
Solution: add the counter to the case class’ arguments
(cascading into all dispatchers, mailboxes, other stuff; had to move
deadLetter stuff to ActorSystem again and split its initialization due
to cyclic dependency)
most tests passing, everything compiling, but docs not updated and nasty
thread-leak preventing me from running the whole test-suite (which is
the reason for this commit: I want to chase down that one first).
- the app.mainbus is classified by Class[_] (currently lookup, will
possibly change to sub-class-aware) and accepts AnyRef messages
- LoggingBus handles akka.event-handlers from config specially:
+ start them as system services, supervised by SystemGuardian
+ keep their subscriptions in sync when logLevel_= is called
+ send them InitializeLogger(bus) message before subscribing them (so
they can register for extras like Mute/UnMute)
- two-phased start-up: first phase with actor-less stdout logging, then
subscription of config loggers, then remove stdout logger (logLevels
configurable separately)
- MainBusReaper watches registered receivers and unsubscribes them upon
death (started in phase 2)
- logger factory on Logging object, needs app/bus and log source;
default instance in app.log
