oops

fresh VM to build under Mono 4.3 is not just a script away!

hopefully I have as much luck with the tests this time around.

@stefansedich

nope, errors, errors everywhere.

@Aaronontheweb when does this happen? On CI?

Steffen Forkmann

@forki

Or during VS build?

As discussed, here you go, Andrew--this one is the issue about using alternative config formats besides HOCON: akkadotnet/akka.net#1450

@BrainSlugs83 we'll have cluster singletons as part of Akka.Cluster.Tools plugin. Most of it is already done (including cluster singleton), we just need to write the rest of test specs for them.

@thomaslazar

ok. as soon as i specify any kind of akka.loggers in my test class the EventFilter assertion stuff breaks. even if i specify Akka.Event.StandardOutLogger

anyone know what's up with that?

Implemented a retrying-exponentialbackoff-supervisor. Not meant to be a one-size-fits-all solution. But might be interesting to some ppl nonetheless. https://gist.github.com/Danthar/82e89eff01ba1eb1d4c3

sending Update() to a PersistentView doesn't appear to have any effect.. could I be doing something wrong? Looking through the source of PersistentView I can't find anywhere where it handles this message type.

@ronnyek

is there any chance akka runs under coreclr?

Graeme Bradbury

@GraemeBradbury

@ronnyek don't know if anyones tried.

Weston

@ronnyek

maybe I'll take a crack at it

does it run under mono to your knowledge

Graeme Bradbury

@GraemeBradbury

:+1: tell us how you get on, would be interested to hear how it goes.

I think stefansedich is working on getting 4.3 to work.

Hi, is it possible if i send text file (133KB) from akka server to client Akka ?. i have try but client is not respond

public class HelloActor : UntypedActor
{
public HelloActor()
{
}

protected override void OnReceive(object request)
{
var data = System.IO.File.ReadAllText(AppDomain.CurrentDomain.BaseDirectory+"myfile.txt");
Sender.Forward(data);
}

}
var actor = System.ActorSelection("HelloActor");
return await actor.Ask<string>(null, TimeSpan.FromHours(1));
is it to large for 133 KB txt file ?
and this is my config hocon at server
remote {

    log-sent-messages = on
    log-received-messages = on
    maximum-frame-size = 10MB

Hi guys. Anyone know a link for a good tutorial for a akkadotnet FSM? I have only seen the official documentation but it is quite poor...

Bartosz Sypytkowski

@Horusiath

@chillitom Update on PersistentView triggers it to send ReplayMessages message to the journal. In result it replays events that happened from the last replayed message received

@tru3d3v

Guys. Anyone can explain about large message ? is it to large for 133 KB txt file

???

@Aaronontheweb

@forki thanks! this was on VS build

@tru3d3v 10mb isn't a valid value for that setting

it's expressed as "total bytes"

public long? GetByteSize()
        {
            var res = GetString();
            if (res.EndsWith("b"))
            {
                var v = res.Substring(0, res.Length - 1);
                return long.Parse(v);
            }

            return long.Parse(res);
        }

Aaron Stannard

@Aaronontheweb

so you need to multiply 10 1024 1024 to get 10mb :p

bah, stupid markdown

10 * 1024 * 1024

Stefan Sedich

@stefansedich

or be greedy and go for 1000

Aaron Stannard

@Aaronontheweb

@BrainSlugs83 another hack I've seen for doing this is pinning your "singleton" to the Akka.Cluster leader

you can use gossip messages to tell if a given node is the leader

and when leader == self then create singleton

otherwise have everyone else look for it

there's only 1 leader in the cluster at any time

and leaders change only when the previous leader was gracefully terminated or forcibly removed by a human

which is why that hack works pretty well

@Horusiath nightlies should be working again now

kicking one off

Stefan Sedich

@stefansedich

@ronnyek @GraemeBradbury I am working on getting it to build and run tests which is a nightmare, for one it won't even build under mono 4.2 as some methods used in the IO stuff is not even in mono 4.2 and was only added a month ago.

would be scary to run it without knowing it builds and all tests pass as who knows what is missing at runtime.

@BrainSlugs83

@Horusiath, thanks for the heads up -- @Aaronontheweb -- double thanks, that seems like it will work well -- especially with a persistent actor (new singleton comes up and will get the last committed state) -- I'm thinking if a node gets a message that it's no longer the leader it should stop the singleton actor too...

Is there anyway to specify that certain roles cannot be the leader? (I have some roles in my cluster that are transient.)

(Or the opposite of that, to declare: "only these roles can be the leader?" -- black-list or white-list works for me, just need to keep the transients from becoming leaders.)

Aaron Stannard

@Aaronontheweb

heh, that's a good question - no, there isn't at the moment
