if you mean a way to ensure that no receive method runs forever.. I have looked into this, but there is no fast way to deal with it. there would need to be some supervisor thread that polls that no thread have been executing a receiveblock for too long
During the very early stages of akka.net, I put together this: https://gist.github.com/rogeralsing/8472797 it does what you want, but expensive, and the implementation would beed to be cleaned
but eventually I just moved it to separate spec class
I've seen a similar problem before, back then, it was that some static resources, like NoRouter or DefaultDeploy or whatver, was overwritten by the serializer .. e.g. some primitives took a static resource as an input argument, then the serializer overwrote the properties of the primitive, which was backed by the static resource, and tada , the static resource was corrupted
could that be a similar problem here?
e.g.
public Props() : this(Some.Static.Resource) {} then when the deserializer tried to deserialize an object with such ctor, the injected resource would be corrupted
NoSerializationVerificationNeeded
that will ofc not help if the testlatch is part of a bigger message, but if it is the root, that would make it bypass serialization in inproc systems
neat :) so for persistence, we just need to start making providers? and follow typesafes lead on how to take it out of beta (?)
beside that, I'm currently during writing some tutorial about how to write custom persistence plugins
but I think, that @Aaronontheweb or @jcwrequests may want to try to implement Cassandra plugins for Akka.Persistence
I also hope, that when it will be ready to drop -Pre flag, RavenDB and EventStore creators will want to integrate their services too
@horusiath is your SQL code on your Akka fork? I think it would be a good idea to write them for Cassandra, mongo, postgres and maybe foundation db. I think that the focus should be on the high write throughput DBs. @arronontheweb might have some during opinions about ravendb 😊.
@jcwrequests if you want to start, my sqlserver fork is not what you want (at least for now). Right now I'm hardening Akka.Persistence.Tests (they are randomly failing right now, mostly due to timeouts) and making an Akka.Persistence.TestKit to work easier with. If everything goes right, they could be released soon and then I'll prepare tutorial about how to start persistence plugin development - right now I already have sample code, but it's not commented.
By default we execute on the threadpool, so we don't own those threads.. we can also execute on the GUI thread with the synchronization context dispatcher if you want an actor that updates GUI elements. we dont own that thread either... then we have cases like the new threadpool, that can be used to give some actors a higher priority than the others, those threads are owned by whatever threadpool we use under the hood, but yes you could consider those owned threads I guess.. so we can execute ontop of whatever the current dispatcher decides to run the work on
but in short, akka never does anything to the threads, it just executes the mailbox run on whatever scheduling mechanism is there
I do have a question for the group though on how you would handle supervision in this scenario: https://gist.github.com/stefansedich/0c5e1d2ac431eccd9fed
In this scenario say DoStuff failed, I would want to restart the child, but to do that I would need to execute the Start message again to reset the internal state back to a starting point before kicking off again, what are the best ways to achieve this kind of thing?
My current solution is to pass a message to the parent, but I end up implementing my own retry and not taking advantage of the Supervisor strategy.
