Why am I getting this timeout during unit test of akka-stream?

Asked 2021-Jan-29 at 13:29

I have an akka-gRPC service BiDirectional stream and I am testing it on a unit test. The service has uses akka-stream and I use the TestSink.probe to test the reply message. I am receiving back the messages from the service, but there is an error related to timeout that I cannot figure out what is the reason. This is the test:

I got it to work based on the project akka-grpc-quickstart-scala.g8. I am executing runForeach to run the graph and have a materialized Sink on the response stream. Then, when the response is done I am doing an assert inside the Future[Done].

Unable to import compiled java avro files into Scala codebase

Asked 2020-Sep-08 at 10:58

I am trying to reference the generated Avro files in my scala code basebase. I am using the commercehub avro gradle plugin to generate the avro java compiled files and they get correctly generated in build/generated-main-avro-java/

This is how my gradle file looks. The problem is that the java files get generated correctly but I cannot import them in my scala code. Any idea on what I maybe doing wrong here?

I would say, you need to add the generated sources folder to source sets and scala compiler source - something like this:

Akka gRPC + Slick application causes "IllegalStateException: Cannot initialize ExecutionContext; AsyncExecutor already shut down"

Asked 2020-Aug-06 at 06:10

I try to develop gRPC server with Akka-gRPC and Slick. I also use Airframe for DI.

Source code is here

The issue is that it cause failure if it receive request when execute as gRPC server. If it doesn't start as a gRPC server, but just reads resources from the database, the process succeeds.

What is the difference?

At Follows, It read object from database with slick. ...Component is airframe object. It will use by main module.

I have an HTTP Backend with Scala Play. Works fine. Now I want to set up a gRPC-API on top of it (theoretical this should work).

To set gRPC up I basically followed the akka-quickstart

Looking at your direct dependencies:

"com.lightbend.play" %% "play-grpc-runtime" % "0.8.2" depends on akka-discovery 2.6.4.

You are using Play 2.8.2 which depends on Akka version 2.6.5.

Just add the depencency on akka-discovery 2.6.5 to your dependencies:

QUESTION

How should I test akka-streams RestartingSource usage

Asked 2020-May-19 at 08:51

I'm working on an application that has a couple of long-running streams going, where it subscribes to data about a certain entity and processes that data. These streams should be up 24/7, so we needed to handle failures (network issues etc).

For that purpose, we've wrapped our sources in RestartingSource.

I'm now trying to verify this behaviour, and while it looks like it functions, I'm struggling to create a test where I push in some data, verify that it processes correctly, then send an error, and verify that it reconnects after that and continues processing.

I've boiled that down to this minimal case:

...

ANSWER

Answered 2020-May-19 at 08:51

I figured it out after having had a look at the TestPublisher code. Its subscription is a lazy val. So when RestartSource detects the error, and executes the factory method () => Source.fromPublisher(probe) again, it gets a new Source, but the subscription of the probe is still pointing to the old Source. Changing the code to initialize both a new Source and TestPublisher works.

Ok, following the prerequisites and instructions to use Java 8 the project creation works.

EDIT: Meanwhile, the pull request was accepted and the main repo (https://github.com/akka/akka-grpc-quickstart-java.g8) is up-to-date.

I downloaded the project using sbt new ..., but there was an error within the pom.xml (fixed version: https://github.com/olitazl/akka-grpc-quickstart-java.g8)

The problem of the example project are missing public modifier inside the GreeterServer class.

Therefore, you have to add public to the GreeterServer class and the method main within.
