perfidix's Issues

@Bench annotation without specified number of runs should use number of runs from @BenchClass annotation

Using an @bench annotation, but leaving out the number of runs causes the number of runs to be taken from the Benchmark configuration (default: 10) instead of the runs definition of the @BenchClass annotation on the class (if available).

IllegalAccessException in console

Hi,

This is the the tutorial code (slightly modified because the original didn't work)
When I run this perfidix bench then in the perfidix bench the tests run without errors but in the console I get

Scala support?

Hi Sebastian,

I like to use perfidix/perclipse with Scala. Since 2.10.0-M6 Scala supports the @static annotation.

I translated the hacked tutorial to Scala

package org.example

import org.junit.Assert

import java.util.Random 
import java.util.Stack

import org.junit.BeforeClass
import org.junit.Test  
import org.perfidix.annotation._
import scala.annotation.static

object FastIntStack2Test {

  @static
  private[FastIntStack2Test] var data = new Array[Int](15)

  @BeforeBenchClass
  @BeforeClass
  @static
  def beforeClass() {
    for (i <- 0 until data.length)  {
      data(i) = new Random().nextInt()
    }
  }
}


@BenchClass(runs = 100)
class FastIntStack2Test {

  val static = FastIntStack2Test

  @Test
  def myStackTest() {
    var myStack = new FastIntStack()
    for (i <- 0 until static.data.length) {
      myStack.push(static.data(i))
    }
    for (i <- (static.data.length - 1 to 0 by -1)) {
      assert(static.data(i) == myStack.pop())
    }
  }

  @Test
  def normalStackTest() {
    var normalStack = new Stack[Integer]()
    for (i <- 0 until static.data.length) {
      normalStack.push(static.data(i))
    }
    for (i <- (static.data.length - 1 to 0 by -1)) {
      assert(static.data(i) == normalStack.pop())
    }
  }

  final class FastIntStack {

    private var stack: Array[Int] = new Array[Int](32)
    private var size: Int = _

    final def push(element: Int) {
      if (stack.length == size) {
        var biggerStack = new Array[Int](stack.length << 1)
        System.arraycopy(stack, 0, biggerStack, 0, stack.length)
        stack = biggerStack
      }
      stack(size) = element
      size += 1
    }

    final def peek() : Int = {
      stack(size - 1)
    }

    final def get(position: Int) : Int = {
      stack(position)
    }

    final def pop(): Int = {
      size -= 1
      stack(size)
    }

    final def clear() {
      size = 0
    }
  }
}

but in eclipse nothing happens. In .log I have this error

    at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

When I look into the source op perclipse at org.perfidix.perclipse.util.BenchFinder$Annotation.annotates(BenchFinder.java:315)

private boolean annotates(final IMember member)
            throws JavaModelException {
    final ISourceRange sourceRange = member.getSourceRange();
    final ISourceRange nameRange = member.getNameRange();
    final int charsToSearch =
           nameRange.getOffset() - sourceRange.getOffset();
    final String source =
           member.getSource().substring(0, charsToSearch);
    return foundIn(source);
}

So it has something to do about how perclipse derives names.
A scala sourcefilename doesn't have to correspond to the class name.

Is it possible to make it Scala compatible?

afterLastRun behaves like beforeFirstRun

Just recognized that any bench annotated with 'afterLastRun' acts like 'beforeFirstRun'
