Port of Akka actors for .NET

@Ralf1108 I know that but was hoping to be able to use the automatic naming somehow. If you name them by my own, I will always need some kind of actor-spaning counter and that's it for concurrency...

Marc Piechura

@marcpiechura

Correct, if the stream doesn't get the ack it will not process any more elements

It will also fail if the remote watcher sends a terminated message for the destination actor

but that's not guaranteed because afaik the remote watcher has something like a timeout and if the network failure only occurs for a short time period the actor maybe isn't seen as dead and therefore no terminated message will be send to the stream but the ack is still lost and you have your deadlock

Hello I am having some problems logging fromm within my actor using Nlog.

This is my config

  <akka>
    <hocon>
      <![CDATA[
          akka 
          {
            loggers = ["Akka.Logger.NLog.NLogLogger, Akka.Logger.NLog"]
            # here we are configuring log levels
            stdout-loglevel = DEBUG
            loglevel = DEBUG
            log-config-on-start = on        
            actor 
            {                
                debug 
                {  
                      receive = on 
                      autoreceive = on
                      lifecycle = on
                      event-stream = on
                      unhandled = on
                }
            }
          }
      ]]>
    </hocon>
  </akka>

The only thing I see are the ActorSystem log.

Ricky Blankenaufulland

@ZoolWay

How do you obtain loggers inside your actors and what do you expect to see?

Arsene Tochemey Gandote

@Tochemey

Like this

protected readonly ILoggingAdapter Logging = Context.GetLogger();

Ricky Blankenaufulland

@ZoolWay

And do you see log message you product with this.Logging.Info("Test"); ?

Arsene Tochemey Gandote

@Tochemey

Nope

Ricky Blankenaufulland

@ZoolWay

And when you do a regular nlog logging outside of the actor system it works?

Arsene Tochemey Gandote

@Tochemey

Yes

Arsene Tochemey Gandote

@Tochemey

Anu idea of what is going on?

Can it be because I am using the TestKit?

Arjen Smits

@Danthar

that could be, the testkit loads its own config

you can append/override with a custom constructor in your test class

Arsene Tochemey Gandote

@Tochemey

How do I go about it?

Jared Lobberecht

@Jared314

is the Akka.Persistence.SqlServer nuget package going to be updated for 1.1?

The source has been updated, but the nuget package isn't there

Arjen Smits

@Danthar

@Tochemey there are multiple constructors you can override

 public MyTestClass(string config) : base(config)
        {
                //load your string here? or use the constructor that takes a Config class instead of a string
        }

Kris Schepers

@schepersk

@Jared314 For now, we're just using the 1.0.8-beta versions SQL common and SQL server packages. Seems to be working just fine :-)

Jared Lobberecht

@Jared314

@schepersk I am also using 1.0.8, but I also need to start using the query api to build out some historical reporting and file export features

Alex Valuyskiy

@alexvaluyskiy

@Jared314 @schepersk we are planning to release it today

Ralf

@Ralf1108

@ZoolWay why not use a guid instead of a counter?

@Silv3rcircl3 so it's still an unresolved problem?

Marc Piechura

@marcpiechura

@Ralf1108 yes, you shouldn't use Akka.Streams with remote actors

Noel

@nanderto

@ @alexvaluyskiy do you mean a separate repository under my account? I don't imagine that I have access under Akka.net

Alex Valuyskiy

@alexvaluyskiy

Yes, under your account

Noel

@nanderto

ok no problem I will get it done today

Ralf

@Ralf1108

@Silv3rcircl3 sad to hear that. Thought that was the point in "Akka Streams".... to distribute stream processing over many machines. WIthout that it is only a Streams implementation with local actors.

Marc Piechura

@marcpiechura

@alexvaluyskiy btw I'm done with the adapter for azure if you want to take a look

William Austin

@wyldebill

i want to use akka.net actors in a simple domain as such - you find interesting places and submit their lat/long to the system. the system catalogs it and makes it available for others to search/query. would each place be a separate actor?

Vagif Abilov

@object

@wyldebill do these places need to perform actions by responding to messages? Do they have state? If so, they are good candidates for actors.

Erik Lagerholm

@stabface

Does anyone have a code example of a decorator pattern implementation to use with Akka actors?

Noel

@nanderto

@alexvaluyskiy I have added the service fabric under my account, https://github.com/nanderto/Akka.Net.Persistence.ServiceFabric/tree/master/src/Akka.Persistence.ServiceFabric

Marc Piechura

@marcpiechura

@nanderto why haven't you forked the existing repository ? https://github.com/akkadotnet/Akka.Persistence.ServiceFabric

Noel

@nanderto

@Silv3rcircl3 the implementation is different from the previous one at that location and when I asked on this gitter if there was interest in my alternative, @alexvaluyskiy suggested that I create a new repository for it under my account.

Daniel Söderberg

@raskolnikoov

Hello! I would like some help with my akka cluster. I wont get it to work when I try to call an actor in the cluster. Dead letters all the time. Im swedish so If you want to help me in swedish you can do that.

Alex Valuyskiy

@alexvaluyskiy

@nanderto why are you using Wire for serialization? Wire is designed for ... wire. For remoting and clustering. But not for persistent. You should choose the closest serializer to your storage. In many cases it is JSON. You also could use serializers like Protobuf in this cases. Maybe @rogeralsing is not agree with me

Noel

@nanderto

@alexvaluyskiy I thought I would try it out, the standard Service Fabric way of serializing does not work at least, and it seemed like a good alternative for Akka, I am not sure I understand your objection, but I assumed that at some point it would be configurable, and users could choose there own.

Peter Bergman

@peter-bannerflow

@raskolnikoov I'm swedish so you can PM me in swedish if u want to and I'll see if I can help

@Tochemey

Hello How long does it take ActorSystem to properly shutdown? because I got this in my log and I have not received any successful shutdown confirmation.

[DEBUG][16:08:02 09:15:45][ActorSystemImpl] System shutdown initiated

However I am running it inside Owin.

Arjen Smits

@Danthar

@Tochemey normally its pretty quick, since there is no real way to block system shutdown.

It does need to spin down all your actors, so if you have alot, it might take abit longer, but even then it should be a few seconds at most

(and by alot i mean a few million :P)

Arsene Tochemey Gandote

@Tochemey

@Danthar Is there a proper way to implement the shutdown?

Arjen Smits

@Danthar

there is not a one size fits all solution

it depends on what your actors are doing
