ANNOUNCE: Akka 2.1.0-RC1 - (Codename: Mingus)

[√iktor Ҡlang]

Dear hAkkers,

We—the Akka committers—are pleased to be able to announce the availability of Akka 2.1.0-RC1 (RELEASE CANDIDATE 1).

This is what we want Akka 2.1 to be, so take it for a spin and give feedback before 2.1.0 goes final!

IMPORTANT NOTICE

The artifacts comprising this release candidate have been published to https://oss.sonatype.org/content/repositories/releases/ and also to Maven Central. In addition, we adopted the SBT standard of encoding the Scala version in the artifact name, i.e. the core actor package’s artifactId is “akka-actor_2.1.0-RC1”.

Summary of Changes since Akka 2.0.3

Akka 2.1.0-RC1 has been created by a total of 37 distinct contributors who have fixed 407 tickets, and the difference between it and 2.0.3:

1171 files changed, 85864 insertions(+), 63975 deletions(-)

We are also proud to say that there is 110(!) pages more in the Akka Reference Documentation (425 pages now versus 315 for 2.0.3).

Most notable new features:

– Built on Scala 2.10

- Akka Camel

- Akka OSGi (all modules)

- Akka Encrypted Remoting (SSL/TLS)

- Integration with scala.concurrent (SIP-14)

- Akka DeathWatch 2

- Akka ActorDSL

&

- Akka Cluster Membership (EXPERIMENTAL)

+ tons of performance improvements, API improvements, defects rectified and even more ScalaDocs.

Take her for a spin!

akka-agent-RC1 on maven-central has incorrect dependencies.  When SBT downloads akka-agent RC1 SBT tries to pull it's dependency:  org.scala-tools#scala-stm_2.10.0-RC1;0.6.  This doesn't exist.  It looks like akka-agent-RC1 was posted to maven central on 16-Oct-2012, and the scala-stm dependency's groupId was fixed on github the following day, in master branch but not in the "releasing-2.1.0-RC1" branch, so the RC1 version of akka-agent on maven central cannot find it's dependency which makes it pretty unuseable.  It'd be great if you guys would replace the version on maven central with one that can find it's scala-stm dependency.

Thanks,

Chris

[√iktor Ҡlang]

Just add OSS sonatype releases repo and it'll find it.
It has been fixed for the next release.

Cheers,

Awesome!  Thanks to everyone involved for creating such an amazing toolkit. 

The documentation is  one of the best I've ever seen for an open source project and together with the 3 upcoming

books it shouldn't be a problem for anyone to gain a deep knowledge of Akka.

Did something weird happen with Duration with Scala from M2 to RC1? Like a move from scala.concurrent.util.Duration to scala.concurrent.util.duration.Duration? I'm getting some compilation errors around Duration.

As well as scala.concurrent.duration.Duration.parse(string) doesn't exist but scala.concurrent.util.Duration.parse(string) did.

Yes, it moved from concurrent.util to concurrent.duration: http://www.scala-lang.org/archives/downloads/distrib/files/nightly/docs/library/index.html#scala.concurrent.duration.package

[Antony Stubbs]

Thanks for verifying. 

What happened to Duration.parse? Do we need to use Duration.create instead? Seems they've replaced it. I can't find any scala release notes about the topic..

Also other compile errors:

akka.pattern.Patterns.gracefulStop(queueActor, Duration.create("60s"), actorSystem); :

gracefulStop(akka.actor.ActorRef,scala.concurrent.duration.FiniteDuration,akka.actor.ActorSystem) in akka.pattern.Patterns cannot be applied to (akka.actor.ActorRef,scala.concurrent.duration.Duration,akka.actor.ActorSystem)

Camel:

replyTimeout() in x.WebServicesConsumerActor cannot implement replyTimeout() in akka.camel.Consumer; attempting to use incompatible return type

found   : scala.concurrent.duration.Duration

I'll post again if I figure it out...

Hi Anthony,

have you read this: http://doc.akka.io/docs/akka/2.1.0-RC1/project/migration-guide-2.0.x-2.1.x.html

Hope that helps!

Cheers,

√

[Antony Stubbs]

Thanks for the nudge victor. I had read the M1 and M2 versions, but had read the RC1 version (didn't realise).

Copied out of the document though,  final FiniteDuration d = Duration.create("1 second"); gives me this error:

incompatible types

found   : scala.concurrent.duration.Duration

required: scala.concurrent.duration.FiniteDuration

With a cast, it works at runtime.

It doesn't mention the camel removal of getHeader though.

I changed to using the form:

cm.getHeaderAs(Exchange.HTTP_SERVLET_REQUEST, Request.class, camelContext);

To get a FiniteDuration: Duration.create(1, TimeUnit.SECOND) //or import static java.util.concurrent.TimeUnit.*;

Using the create(String) could yield an infinite/undefined duration

Casting is for wizards, not programmers :-)

Looks good. I'll see if I can't add that to the migration docs.

[Antony Stubbs]

Roger that, and agreed ;)

[Antony Stubbs]

Doesn't that also mean you need to change 

FiniteDuration d = Duration.create("1 second"); 

To

FiniteDuration d = Duration.create(1, SECOND);

?

[√iktor Ҡlang]

I believe I specifically said that in my previous email.

[Antony Stubbs]

Sorry, I thought you were specifically talking about the camel get header as change. 

Sweet as.

Dear committers,

Thanks for an awesome release.   The documentation and examples are second to none for an open source project.

• I was able to get all the Akka cluster examples working!   I instrumented the StatsSample example and it was really neat watching the work get distributed more evenly as I added nodes and removed them.
• ConsistentHashingRouter does not seem to consistently send work to the same remote actors, in the example anyways.  My guess is that each JVM must be getting the membership list in slightly different order, or something like that.  Might be good for them to communicate to ensure the hashing is the same.
• In the StatsSample, the client should probably not be part of the cluster, but instead connect to one of the nodes, which is how things will probably work in reality.   I may do this to debug the ConsistentHash problem above.
• I had some trouble initially with SBT not able to compile Scala 2.10.   Somehow magically figured it out.

Good work again,

Evan

That sounds wrong. I will investigate it tomorrow, but I immediately got an idea of what can be wrong. The hash ring consists of the actor refs of the the routees and on different nodes they actually have different representations because the local actor ref doesn't contain the address (hostname:port)

 

• In the StatsSample, the client should probably not be part of the cluster, but instead connect to one of the nodes, which is how things will probably work in reality.   I may do this to debug the ConsistentHash problem above.

The idea was to avoid addresses in the client also, and make sure it continuous to work also when nodes are shut down.

Thanks a lot for finding this bug.

 

By the way, I can't connect to a cluster using a remote ActorRef.  It complains that I need a ClusterActorRefProvider.

That is because application.conf is still used as default and there you have 

extensions = ["akka.cluster.Cluster"]

which means that the cluster extension will be started, etc...

You need to add extensions = [] to your StatsSampleClient config, or use another application.conf

 

So I changed the config to use the ClusterActorRefProvider, and now the message sends just seem to go nowhere.

This works for me:

What version of SBT are you using (the docs is wrong, but SBT 0.12 should find it in the standard plugins repo)

If you're on SBT 0.11 you can try this: resolvers += "SBT plugins repository" at "http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases"

instead of the typesafe repo

[Dennis Horte]

I was initially running 0.12.0. After reading your response, I tried 0.12.1 and 0.11.2, including the additional resolver you recommended. All gave the same result.

The warning messages are saying that it is trying to use scala_2.9.2 (example below), rather than 2.10.0-RC1. Could that be the source of the problem?

[warn] ==== typesafe-ivy-releases: tried

[warn]   http://repo.typesafe.com/typesafe/ivy-releases/com.typesafe.akka/akka-sbt-plugin/scala_2.9.2/sbt_0.12/2.1.0-RC1/ivys/ivy.xml

My Build.scala file specifies scalaVersion = 2.10.0-RC1. Is there some way I need to specify it also for the plugins.sbt?

Regards,

Dennis

[√iktor Ҡlang]

Ah, that's a good point, we recently started publishing binary versions as a part of the artifact id.

Try: addSbtPlugin("com.typesafe.akka" %% "akka-sbt-plugin" % "2.1.0-RC1" cross CrossVersion.full)

[√iktor Ҡlang]

https://github.com/akka/akka/pull/841/files

[Dennis Horte]

Without the CrossVersion and with the CrossVersion, it is still resolving to the same URL for lookups.

eg. http://repo.typesafe.com/typesafe/releases/com/typesafe/akka/akka-sbt-plugin_2.9.2_0.12/2.1.0-RC1/akka-sbt-plugin-2.1.0-RC1.pom

I also tried explicitly adding the scala version to the plugin name following the style used in the Build.scala for akka dependencies, like so:

addSbtPlugin("com.typesafe.akka" % "akka-sbt-plugin_2.10.0-RC1" % "2.1.0-RC1")

This also doesn't resolve the problem.

Regards,

Dennis

[√iktor Ҡlang]

Hmmm, this is annoying, seems like it only gets published for 2.9.1, need to investigate.

http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases/com.typesafe.akka/akka-sbt-plugin/scala_2.9.1/sbt_0.12/2.1.0-RC1/

[√iktor Ҡlang]

I'll change the scalaBinaryVersion to "2.9" instead of scalaVersion for the next release (SBT uses Scala 2.9 internally)

[Dennis Horte]

Is there a workaround until the next release, or should we continue with Akka 2.0 until then?

Dennis

[√iktor Ҡlang]

Yes, use the full artifact id, see the link I sent, that should work.

[Dennis Horte]

I'm not sure how to use that URL. How do I setup the plugins.sbt file?

Regards,

Dennis

[√iktor Ҡlang]

try

addSbtPlugin("com.typesafe.akka" % "akka-sbt-plugin_2.9.1" % "2.1.0-RC1")

[Dennis Horte]

Unfortunately, the artifactonline repository is resolved as follows using that.

http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases/com/typesafe/akka/akka-sbt-plugin_2.9.1_2.9.2_0.12/2.1.0-RC1/akka-sbt-plugin_2.9.1-2.1.0-RC1.pom

If I change remove the _2.9.1, change to sbt 0.11.2, then it generates the following line:

http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases/com/typesafe/akka/akka-sbt-plugin_2.9.1_0.11.2/2.1.0-RC1/akka-sbt-plugin-2.1.0-RC1.pom

It is similar with sbt 0.12.1 and the _2.9.1 removed:

The mapping that is being done does not seem to match the URL you provided. Is there some way that the mapping can be tweaked? Since it is different for each resolver, I have to guess that it is managed server side rather than by sbt.

Wow, I'm sorry about this, I'll try to fix this tomorrow for RC2

Cheers,

Alright. Thanks for all your effort. I'll try again with RC2.

If you use SBT 0.12, does the following work for you?

addSbtPlugin("com.typesafe.akka" % "akka-sbt-plugin" % "2.1.0-RC1" cross CrossVersion.selectVersion("2.9.1","0.12"))

[Dennis Horte]

It gives the following error:

/home/dennis/workspace/GameLearner/project/plugin.sbt:5: error: overloaded method value cross with alternatives:

  (v: sbt.CrossVersion)sbt.ModuleID <and>

  (v: Boolean)sbt.ModuleID

 cannot be applied to (String)

addSbtPlugin("com.typesafe.akka" % "akka-sbt-plugin" % "2.1.0-RC1" cross CrossVersion.selectVersion("2.9.1","0.12"))

Are you 100% sure you're using SBT 0.12?

Because it works on my machine: addSbtPlugin("com.typesafe.akka" % "akka-sbt-plugin" % "2.1.0-RC1" cross CrossVersion.selectVersion("2.9.1","0.12"))

[Dennis Horte]

I did the below test. If it is working for you, then could there be some hidden configuration steps that I am missing. Perhaps you have some global settings?

dennis@liberty-2:~$ mkdir workspace/tmp

dennis@liberty-2:~$ cd workspace/tmp

dennis@liberty-2:~/workspace/tmp$ sbt

[info] Set current project to default-de2fa9 (in build file:/home/dennis/workspace/tmp/)

resolvers += "SBT plugins repository" at "http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases"

addSbtPlugin("com.typesafe.akka" % "akka-sbt-plugin" % "2.1.0-RC1" cross CrossVersion.selectVersion("2.9.1","0.12"))

Hmm, what if you use SBT 0.12.1?

[Dennis Horte]

I'm pretty sure hat test was using 0.12.1. To do the test, I redownloaded sbt from http://www.scala-sbt.org/release/docs/Getting-Started/Setup.html, using the download sbt-launch.jar link in the Unix section, making sure that 0.12.1 was selected in the version dropdown at the top of the page. I created a new sbt script in my bin directory. 'which sbt' shows the correct script file, so I don't think I am inadvertently running a different version.

Also, make sure you have a project/build.properties with content:

sbt.version=0.12.1

I'll have to investigate this a bit further. Seems like there could be some change in how the plugins are published.

[Peter Vlugter]

I've republished the 2.1.0-RC1 version of akka-sbt-plugin with the correct scala version.

Using sbt 0.12 only the following in project/plugins.sbt should be needed:

addSbtPlugin("com.typesafe.akka" % "akka-sbt-plugin" % "2.1.0-RC1")

There are a couple of small changes needed for the sample project. I've created an updated version here:

Awesome Peter.

[Dennis Horte]

Patrick,

I was using the build.properties to set the sbt version for all of my previous tests. For the sake of completeness, I redid the final test with the build.properties file specifying 0.12.1, but the results were the same.

Regards,

Dennis

[Dennis Horte]

Thanks Peter. That solves the problem completely.

Regards,

Dennis
