From 3b3bcd7b684fc432e48c20aa5317b56e87521c3b Mon Sep 17 00:00:00 2001 From: Jason Zaugg Date: Thu, 14 Nov 2013 20:03:20 +0100 Subject: Revert "temporarily disables run/reflection-sync-subtypes" This reverts commit 04e2dbb29830d0e511cdfa8c132a9fad91d657ed, by avoiding the ill-fated attempt to short-circuit the global reflection lock. I think we can do better performance wise, but lets at least get something correct to start with. --- test/files/run/reflection-sync-subtypes.check | 0 test/files/run/reflection-sync-subtypes.scala | 20 ++++++++++++++++++++ 2 files changed, 20 insertions(+) create mode 100644 test/files/run/reflection-sync-subtypes.check create mode 100644 test/files/run/reflection-sync-subtypes.scala (limited to 'test/files') diff --git a/test/files/run/reflection-sync-subtypes.check b/test/files/run/reflection-sync-subtypes.check new file mode 100644 index 0000000000..e69de29bb2 diff --git a/test/files/run/reflection-sync-subtypes.scala b/test/files/run/reflection-sync-subtypes.scala new file mode 100644 index 0000000000..7f75a464ac --- /dev/null +++ b/test/files/run/reflection-sync-subtypes.scala @@ -0,0 +1,20 @@ +import scala.reflect.runtime.universe._ + +object Test extends App { + val n = 1000 + val rng = new scala.util.Random() + val tasks = List( + () => typeOf[List[Int]] <:< typeOf[List[T] forSome { type T }], + () => typeOf[List[T] forSome { type T }] <:< typeOf[List[Any]], + () => typeOf[Map[Int, Object]] <:< typeOf[Iterable[(Int, String)]], + () => typeOf[Expr[Any] { val mirror: rootMirror.type }] <:< typeOf[Expr[List[List[List[Int]]]]{ val mirror: rootMirror.type }]) + val perms = tasks.permutations.toList + val diceRolls = List.fill(n)(rng.nextInt(perms.length)) + val threads = (1 to n) map (i => new Thread(s"Reflector-$i") { + override def run(): Unit = { + val result = perms(diceRolls(i - 1)).map(_()) + assert(result.sorted == List(false, false, true, true)) + } + }) + threads foreach (_.start) +} \ No newline at end of file -- cgit v1.2.3
