implicits and type erasures in scalabeans

Hi All - I'm a scala noob and could do with a hint on this, I suspect this is a type erasure style problem but am only just learning the scala type system so thought I'd check with the experts....

I've been playing with the cool scalabeans framework and looking to deserialize a config file into a scala class instance and I wanted to use a neat implicit for the class type based on the return type rather then explicitly pass the classOf as the argument. However the implicit type seems to get swallowed into a java.lang.Object on route:

so the sweetConfig call fails with a java.lang.ClassCastException: java.lang.Object cannot be cast to SystemConfig

import org.scalatest.FunSuite

import java.io.File

import org.scalastuff.scalabeans.Preamble._

class ConfigTest extends FunSuite{

test("Loading example-config"){

var uglyConfig: SystemConfig = deserializeConfigWithClassOf(classOf[SystemConfig],new File("example-config.conf"))

var sweetConfig: SystemConfig = deserializeConfig(new File("example-config.conf"))

}

def deserializeConfigWithClassOf[T <: AnyRef:Manifest](clz: Class[T], file: File) : T = {

val config = descriptorOf[T].newInstance().asInstanceOf[T]

config

}

def deserializeConfig[T <: AnyRef:Manifest](file: File) : T = {

val config = descriptorOf[T].newInstance().asInstanceOf[T]

config

}

class SystemConfig {

var appName: String = ""

}

any advice on cutting out the explicit classOf[] or how to remove the asInstanceOf[] cast would be appreciated!

Re: Nested Wrappers again

Hi,

I tested the concept in my project and it works very well. Now I have
some problems with implicits as they don't automatically apply. I added
another type member 'Nested' that holds the exact type of the nested
wrapper and a new attribute 'nested' that holds the instance of the
nested wrapper.
As each concrete wrapper class can have its own specific methods I
created an implicit to automatically unwrap a nested wrapper from its
nesting class.
The following code in the main method produces a compiler error since
the implicit is not applied automatically. Is there any hint to achieve
this?
Any ideas? I used Scala 2.9.2 and 2.9.3.

    trait Wrapper[A]
    {
        type W[X] <: Wrapper[X]
        type Nested <: Wrapper[A]

        val nested: Nested
    }

    class Base[A](val value: A) extends Wrapper[A] {
        type W[X] = Base[X]
        type Nested = this.type

        val nested: Nested = this
      }

    class AWrapper[A, B <: Wrapper[A]](val nestedWrapper: B with
Wrapper[A]) extends Wrapper[A] {
        type W[X] = AWrapper[X, B#W[X]]
        type Nested = B

        val nested = nestedWrapper.asInstanceOf[Nested] // This is
necessary, otherwise it won't compile

        def methodOfAWrapper: Unit = Unit
      }

   
    class AnotherWrapper[A, B <: Wrapper[A]](val nestedWrapper: B with
Wrapper[A]) extends Wrapper[A] {
        type W[X] = AnotherWrapper[X, B#W[X]]
        type Nested = B

        val nested = nestedWrapper.asInstanceOf[Nested]

        def methodOfAnotherWrapper: Unit = Unit
      }

object Main
{   
    def main(args: Array[String]): Unit =
    {
        val b = new Base(5)
        val a = new AWrapper(b)
        val an = new AnotherWrapper(a)

        implicit def unwrap1[A, W <: Wrapper[A]](w: W with Wrapper[A]):
W#Nested = w.nested

        val z = an.methodOfAnotherWrapper
        val y = an.methodOfAWrapper             // error due to failure
in implicit
        val x = unwrap1(an).methodOfAWrapper     // but this works !!!!
    }   
}

when namespaces collide

In general a source file is treated as if it had these leading imports:

import java.lang._

import scala._

import Predef._

This means the imported identifiers are subject to being masked. Now where do identifiers come from? One place you get root-scoped identifiers is from your classpath. Every top-level package is an identifier. Which are the top-level packages? Beyond those in jars, for every directory on your classpath, every direct subdirectory is a top-level package, at least in the mind of scalac.

This has extremely perverse consequences:

% scalac ./a.scala

% mkdir any2stringadd

% scalac ./a.scala

./a.scala:2: error: value + is not a member of object Test

println(this + "")

one error found

The only thing more fun than a bug like that is watching it come and go based on your current working directory, since "." is the default classpath.

This came to my attention most recently because we have source files which do things like this:

self: tools.nsc.Global =>

This can't be compiled from the repository root without changing one's classpath because the repository has a root-level directory called "tools". There are no classfiles in that directory, but scalac doesn't care, it's going to shadow scala.tools.

Surely we don't have to accept this quantity of non-determinism.

Re: when namespaces collide

I, just recently, ran into trouble using tuples when a sub package was named "scala".

Re: when namespaces collide

If you have a strong stomach, see the attached files, which are the output from attempting to compile each of (compiler, library, reflect) after doing this:

mkdir $(find /scala/trunk/src/{library,compiler,reflect}/scala -maxdepth 1 -type d |xargs basename |sort -u)

Which gives us these empty directories:

annotation beans collection compat concurrent io math parallel

ref reflect runtime scala sys testing text tools util xml

Not only do all of them explode horribly, 2/3 crash (in different ways) which strongly suggests the compiler is preferring these empty directories to its own scala subpackages not only for resolving the identifiers in source code but during its operation. Here's what we can see it admit to before the forces of crashiness overwhelm the defenses.

Remember, the only thing making all this happen is that there are some empty subdirectories of my current directory.

Re: [scala-user] Caching implicit convertion: map.getOrElseUpdate throws unexpected exception

[Redirected to scala-language since I'm not on scala-user.]

Someone asked me recently why I'm against extending Function1 casually. In this we have a pretty good example. I'm not sure why you declared the map to be an implicit val:

implicit val cache = mutable.Map[Int, String]()

I imagine you didn't do that with the intention of placing a competing implicit conversion in scope, because your Map is also an Int => String. And for whatever reason it's not ambiguous - the val is preferred over the def I guess.

So this line:

println(3.startsWith("whatever"))

Is using the cache directly to implicitly convert Int to String, i.e. it's calling cache.apply, not cache.getOrElseUpdate.

Hi!

I would like to have an implicit conversion with caching of the results (in a mutable map). However, when called implicitly, the map's getOrElseUpdate throws an exception. The following is a simplification of my real code (in particular, in my real code the conversion is not between Int and String).

  import language.implicitConversions

import collection.mutable.{Map => MMap}

  implicit val cache : MMap[Int, String] = MMap()

implicit def intToString(p: Int): String = cache.getOrElseUpdate(p, "number " + p.toString + " !" )





// Everything works fine in the following line,

// "false" is printed and (2 -> "number 2 !") is added to cache as expected

println(intToString(2).startsWith("whatever"))

// But when intToString is called implicitly, as in the line below, an exception is thrown

  println(3.startsWith("whatever")) // But here, surprisingly, an exception is thrown

The exception message is:

Is this a bug of the Scala (2.10.0-M5) language? It seems to me that getOrElseUpdate tries something and catches an exception if the key is not found, but for some reason the exception is escaping the catch when the call to getOrElseUpdate is made from within an implicitly called implicit conversion...

Or is this expected behavior? If so, what should I do to make getOrElseUpdate work also from within an implicit call?

I would also be happy to hear any alternative idea for implementing an implicit converter that caches and reuses the conversions.

Best regards,

Bruno

Re: implicits and type erasures in scalabeans

Hi All - I'm a scala noob and could do with a hint on this, I suspect this is a type erasure style problem but am only just learning the scala type system so thought I'd check with the experts....

I've been playing with the cool scalabeans framework and looking to deserialize a config file into a scala class instance and I wanted to use a neat implicit for the class type based on the return type rather then explicitly pass the classOf as the argument. However the implicit type seems to get swallowed into a java.lang.Object on route:

so the sweetConfig call fails with a java.lang.ClassCastException: java.lang.Object cannot be cast to SystemConfig

import org.scalatest.FunSuite

import java.io.File

import org.scalastuff.scalabeans.Preamble._

class ConfigTest extends FunSuite{

test("Loading example-config"){

var uglyConfig: SystemConfig = deserializeConfigWithClassOf(classOf[SystemConfig],new File("example-config.conf"))

var sweetConfig: SystemConfig = deserializeConfig(new File("example-config.conf"))

You should write instead

var sweetConfig = deserializeConfig[SystemConfig](new File("example-config.conf"))

which has as much typing but will in fact work (disclaimer: I didn't test it). In deserializeConfigWithClassOf, you pass classOf[T] just to allow Scalac to deduce T; just giving up on type inference works better.

Now, you might still wonder what's happening in your code?

I guess, since the return type is SystemConfig, you would like deserializeConfig() to become deserializeConfig[SystemConfig]. I see why this looks reasonable; however, scalac will in fact deduce T = Nothing. Since Nothing is a subtype of every type, the code typechecks.

Nothing is a type only in Scala, but it does not exist in Java, so it's represented by Object at runtime, like Any and AnyRef; that's why the Class[_] instance you see is an instance of Object.

With Scala 2.10 and TypeTags, which preserve more information, it's easier to verify this:

import scala.reflect.runtime.universe._

def f[T <: AnyRef: TypeTag]: T = {println(typeTag[T]); null.asInstanceOf[T]}

scala> f: String

TypeTag[Nothing]

res1: String = null

But in general, it's often simpler to just pass -Xprint:typer to the compiler, to make it print the source code as transformed by type inference, to be able to examine it. In the example above, you would see what T is deduced to be (in this case, I believe, Nothing).

Best regards

Paolo G. Giarrusso

any advice on cutting out the explicit classOf[] or how to remove the asInstanceOf[] cast would be appreciated!

About asInstanceOf, it does not seem possible to remove it with the current version of ScalaBeans. newInstance returns just AnyRef, not T. I believe you should ask the author to change the library; even with raw Java reflection, classOf[T].newInstance will have T as static type, so no cast is needed! So also Scalabeans should offer such safety.

Unfortunately, I don't know myself a better library to recommend.

Best,

Paolo Giarrusso

Re: when namespaces collide

Can we open a bug for that? Is there one?

Mine had to do with having a relative scala package destroying Tuple extractor usage, even with manual _root_ imports. I'll try to deduplicate when I have the chance.

If you have a strong stomach, see the attached files, which are the output from attempting to compile each of (compiler, library, reflect) after doing this:

Which gives us these empty directories:

annotation beans collection compat concurrent io math parallel

ref reflect runtime scala sys testing text tools util xml

Not only do all of them explode horribly, 2/3 crash (in different ways) which strongly suggests the compiler is preferring these empty directories to its own scala subpackages not only for resolving the identifiers in source code but during its operation. Here's what we can see it admit to before the forces of crashiness overwhelm the defenses.

Remember, the only thing making all this happen is that there are some empty subdirectories of my current directory.

I know too well why that is. However I tried once long ago to construct all internal names with _root_ and it didn't work for reasons I couldn't figure out at the time. But clearly the fact that we synthesize trees like Select(Ident("scala"), "Tuple2") is going to break down when scala is shadowed.

I can straightforwardly deal with the interactions I'm describing in this thread in all cases except if "scala" itself is shadowed. The changes necessary to really deal with that, I don't see them happening. I'd much rather disallow or at least openly discourage scala as a package name. One has to pick one's time-consuming battles.
