Aaron Stannard

@Aaronontheweb

hey dude

Stefan Sedich

@stefansedich

what is the deal to actually run tests locally without stack overflows?

have not had much luck running the suite.

Aaron Stannard

@Aaronontheweb

hahaha.... upgrading XUnit :(

2.0 RTM is out now, but I don't know if any of us have tried upgrading to it yet

since we had a lot of trouble with the release candidates

Stefan Sedich

@stefansedich

heh ok, my r# is boned can't see any extensions I had just been running with build.bat RunTests for now.

Aaron Stannard

@Aaronontheweb

lol

love it when that happens

Stefan Sedich

@stefansedich

I see one extension in the available list

such selection

Aaron Stannard

@Aaronontheweb

@stefansedich I'm not going to be able to take on the Mono build server for the next couple of days - have some Akka.NET v1.0 deliverables I need to finish first :p

I'll try to get that done ASAP though

Stefan Sedich

@stefansedich

too easy

as soon as you can get me access let me know I will spin it all up and get it working next week.

Aaron Stannard

@Aaronontheweb

sounds good buddy

Stefan Sedich

@stefansedich

has anyone here done any work on a kafka consumer?

Stefan Sedich

@stefansedich

Say I am listening to a terminated child to be able to fail a parent process, how does one get information on why that child died? should a child be sending a message to the parent upon termination? can I hook into that by any chance?

Stefan Sedich

@stefansedich

I want to know why my child died to be able to update a record that my parent keeps track of, say it is an AWS exception I want to update with "file not found" for example.

Roger Johansson

@rogeralsing

@stefansedich protected override void PreRestart(Exception reason, object message) should work?

or you mean before termination?

David Smith

@smalldave

@Aaronontheweb looking at restartnodespec. it downs one system and then brings up another but on the same port. this isn't working. the new system seems to work fine but the cluster leader can't send InitJoinAck to the new system so it never joins. I've tracked it down to the endpointwriter on the cluster leader for the new systems (and presumably the old systems) endpoint. it never changes message handler from Initialized and just keeps buffering the message. Any guess what is happening here? Is the endpoint writer likely to be the endpoint writer for the first system that has been shutdown. Should this matter?

David Smith

@smalldave

@Aaronontheweb ignore all that

Is there an equivalent of the JVM system.registerOnTermination? Rather nasty bug. When the actor system shuts down it doesn't leave the cluster!

Stefan Sedich

@stefansedich

yeah @rogeralsing before termination.

argh what the hell have they done to the new mongodb c# driver, put some load on my api and CPU get pinned, all from the linq parsing.

Stefan Sedich

@stefansedich

just grabbed akka in action for my flight :)

working out how to get it onto this iPad I borrowed from work is half the battle.

Roger Johansson

@rogeralsing

im using Voice Dream to read the ebook version out loud for me :) works like a charm

David Smith

@smalldave

i'm looking at creating some kind of termination hook for actor system

jvm version uses the TerminationCallbacks class which is triggered off TerminationTask

I could do something similar but ActorSystem is disposable. Should I use that instead. I need the hooks to run before the system shuts down.

Andrew Skotzko

@skotzko

@rogeralsing holy crap. Voice Dream is awesome. Thanks! I so need that.

Roger Johansson

@rogeralsing

I bought a voice called Salli, sounds pretty good and works at speeds up to 220ish words per min

Andrew Skotzko

@skotzko

the “James” voice by neospeech is pretty good

Aaron Stannard

@Aaronontheweb

@smalldave looks like we need to add Termination hooks and enable the RemotingTerminator

that explains A LOT

about some of the weird cluster re-join behavior

Bartosz Sypytkowski

@Horusiath

@rogeralsing When I've got an async task inside actor receive, how can I ensure that it's continuation will be able to use actor's context in any way? Or am I forced to use PipeTo?

I need it here: https://github.com/akkadotnet/akka.net/blob/dev/src/core/Akka.Persistence/Journal/AsyncWriteJournal.cs#L120

Roger Johansson

@rogeralsing

There is an overload of Receive that takes an Func<TMessage,Task> , if you use that method, we apply the actor task scheduler and tasks will be scheduled to run inside the actor context

Or. you simply copy Self to self .. var self = Self before invoking the tasks.

@Aaronontheweb fixed one such bug in persistence in his latest dispatcher PR

https://github.com/akkadotnet/akka.net/pull/760/files#diff-9666a109078de1128cffffdf3070e242R121

you only need the Self ref there, right? or do you need to set actor state?

Bartosz Sypytkowski

@Horusiath

I've seen that trick once in canonical akka source code

hopefully it will be enough

Bartosz Sypytkowski

@Horusiath

worked :)

Roger Johansson

@rogeralsing

:+1:

@HCanber @Aaronontheweb which PR do we merge first? which one results in the least amount of re-work? as I take it that they will both break eachother
