* Add CopyrightHeader support for sbt-boilerplate plugin.
* Add CopyrightHeader support for `*.proto` files.
* Add regex match for both `–` and `-` for CopyrightHeader.
* Add CopyrightHeader support for sbt build files.
* Update copyright from 2018 to 2019.
* Improve default shard rebalancing algorithm, #26012
* Use rebalance-threshold=1 because it will give the best distribution,
and previous default could result in too large difference between nodes
* Off by one error, difference > threshold vs >=
* Added more unit tests
* Note that in some cases it may still not be optimal, stopping more
shards than necessary, but a different strategy that looks at more
than most and least is out of scope for this issue. In practise
those cases shouldn't matter much.
* Also note that the rebalance interval is by default 10 seconds,
so typically shards will start up before next rebalance tick.
It's intentionally a slow process to not cause instabilities by
moving too much at the same time.
* Added ActorTestKit#stop method and corresponding tests.
* Added 'Stopping actors' section to the docs
* Stop actor now waits until the actor terminates.
Fixes#25825
Provides search domain support for Async DNS.
There are two parts here, first is the search domain support itself,
which is relatively straight forward - on lookup, create a list of hosts
to attempt to resolve based on the search domains configuration
(including the host with no postfix), exclude all those hosts that have
less dots than the configured ndots, and then search until you find one
that returns any records. In this case the search domains are applied for
each nameserver attempt, so if a particular nameserver times out, it
won't attempt to search any more domains on that nameserver.
The second part is in actually detecting the system configuration. I've
only implemented partial support here, it reads /etc/resolv.conf, and
nothing else. There are ways to detect it on other platforms, there are
also environment variables that are supposed to be honored on Linux and
other *nix's, but to keep this change manageable, I've focussed on just
supporting the minimum to meet the Kubernetes service discovery use case,
and documented the limitations.
* Remove exception from typed Terminated
This currently only works for direct child actors and breaks when using
typed supervision.
It could be re-introduced by supervision returning a new special
behavior that the actor adaper for failed with an exception.
* Try out keeping the terminated and adding a ChildTerminated subclass of Terminated
Some tests need updated will fix those if we decide this is better
* Fix duplicate logging + make it Terminated + ChildFailed
* Import service discovery from akka-management
* Rename extension to Discovery to go with akka-discovery name
* Rename interafce to ServiceDisovery
* Import config, aggregate and dns
* Discovery documentation
* Load isolated async-dns if not configured as default
* OSGi for discovery
* Remove warning for not using in production
* Fail if old akka management on classpath
* Only allow async dns to be loaded as an additional resolver
* Use method in all of service discovery, not mechanism
* Mima filter
* Add discovery to aggregate
* Set discovery mima versions
* DnsDiscoverySpec: Only run docker test if docker available
Specifically:
* avoid "internal", as I initially though that meant the Akka framework's internal state of an actor
* dropped "started" in the context of recovering an actor: in order to recover you have to have been already started
* rather than refering to "changes", reference that what's persisted are the actor's received events
* some general English re-wording
* [ttk] Add access to logged events in BehaviorTestKit #25905
`BehaviorTestKit` now has methods to:
- Access to logged events
- Clear all log events
Added section in docs explaining how to check for logs.
Note about the implementation: `CapturedLogEvent` was effectively private to akka. It uses `OptionVal` internally, this makes it impossible to be used from outside akka. To overcome this, I added some methods to translate it to the corresponding `Option` and `Optional`.
* Apply feedback
Clean up `CapturedLogEvent` by using only `Option` in public methods
Use `immutable.Seq` instead of plain `Seq`
* It's mostly technical concern that is blurring the business logic in the entity
* Async interactions before stopping is often not needed
* Implemented with an internal PoisonPill signal that is added by sharding,
* Persistent actors handle PoisonPill and run side effects after persist
and process stashed messages before stopping.
* remove unecessary stop messages
* reference docs
