sbt test freezes my windows console

[James Black]

I am curious how to troubleshoot this.

I am using Scala 2.9.1

This is the relevant part of build.sbt:
libraryDependencies ++= Seq(
"org.scala-tools.testing" %% "scalacheck" % "1.9",
"org.specs2" %% "specs2-scalaz-core" % "6.0.1",
"org.specs2" %% "specs2" % "1.8.2" % "test",
"junit" % "junit" % "4.7",
"org.specs2" % "classycle" % "1.4.1"
)

and at the moment I am just using this:
import org.specs2.mutable._

class HelloWorldSpec extends Specification {

"The 'Hello world' string" should {
"contain 11 characters" in {
"Hello world" must have size (11)
}
"start with 'Hello'" in {
"Hello world" must startWith("Hello")
}
"end with 'world'" in {
"Hello world" must endWith("world")
}
}
}

I am also using sbt 0.11.2

If I do
sbt test
or
sbt test-only HelloWorldSpec
my console window freezes, I can't even use cntrl-x to break out of
it.

Thank you.

[James Black]

It was cntrl-c, not cntrl-x, sorry about that.

[James Black]

Ok, found out more.

I have this in build.sbt:
testOptions in Test += Tests.Argument("nocolor", "neverstore", "html",
"junitxml", "console")

If I just have
testOptions in Test += Tests.Argument("nocolor", "neverstore",
"console")
then it runs.

So, using html or junitxml is what is causing the freezing.

Use jstack [1] to find out what the process is doing.

Hi James, I'm going to investigate on that because I have a feeling of what is going wrong. 

In the meantime can you try the same with 1.9-SNAPSHOT because I changed part of that code to avoid this kind of issues.

Thanks,

Eric.

[James Black]

Yes, tomorrow I will try it with the newer version, and let you know what happened.

Thank you very much.

I'm afraid I can't reproduce this issue so I'd be very interested in having a thread dump.

Thanks.

I tried this version, and the same behavior is seen.

[etorreborre]

Thanks for the thread dump, James.

Unfortunately I don't see from that thread dump what could go wrong really.

Out of pure guesswork I just published a new 1.9-SNAPSHOT version with a slight change. Please tell me if that works for you. If not I'll try more debugging and possibly something more radical.

What's your machine/OS specs by the way?

Eric.

[James Black]

I am using windows 7.

If needed I can zip up my build.sbt and the test class if it would help.

[James Black]

I am using JDK 1.7.0_02, in case that helps.

I remember there is an issue with the default configuration of the
scala.concurrent thread pool on JDK 7, related to a change in a system
property that identifies the JVM vendor from "Sun" to "Oracle". But I
can't recall the details, nor google them.

Yes, that can help, maybe I overlooked something obvious.

[Jason Zaugg]

git log --grep to the rescue.

Hi James,

I just reviewed the thread dump and thanks to Jason's memory and grepping skills we might have something here.

The stacktrace shows that the " AdaptiveWorkStealingThreadPoolTasks" trait is used where it should be "AdaptiveWorkStealingForkJoinTasks".   
So it might be worth trying to change the System properties like this:

  testOptions in Test += Tests.Setup( () => System.setProperty("java.vm.vendor", "Sun") ) 

 

Eric.

[James Black]

Thank you, I will try that.

I had a high priority issue at work, so I haven't had a chance to go back to this.

[James Black]

I tried this and it worked.  Thank you very much.

That's great news!
