From 1f5dfbd7a6ca915ceb8a5794be568cfab8f97e47 Mon Sep 17 00:00:00 2001 From: Adriaan Moors Date: Tue, 24 Apr 2007 15:17:49 +0000 Subject: fixed bug 1065 This was caused by the Uncurry phase not fully expanding alias types. More specifically, the argument&result types of anonymous functions (Function node) weren't normalized. Presumably other combinations weren't covered either. These should now be fixed. --- test/files/run/typealias_overriding.check | 1 + test/files/run/typealias_overriding.scala | 23 +++++++++++++++++++++++ 2 files changed, 24 insertions(+) create mode 100644 test/files/run/typealias_overriding.check create mode 100644 test/files/run/typealias_overriding.scala (limited to 'test/files') diff --git a/test/files/run/typealias_overriding.check b/test/files/run/typealias_overriding.check new file mode 100644 index 0000000000..2dc752a8c8 --- /dev/null +++ b/test/files/run/typealias_overriding.check @@ -0,0 +1 @@ +LinkedNode diff --git a/test/files/run/typealias_overriding.scala b/test/files/run/typealias_overriding.scala new file mode 100644 index 0000000000..03330498eb --- /dev/null +++ b/test/files/run/typealias_overriding.scala @@ -0,0 +1,23 @@ +// this bug (http://scala-webapps.epfl.ch/bugtracking/bugs/displayItem.do?id=1065) +// was caused by Uncurry not normalizing all the types +// (more specifically the argument/return types of an anonymous Function) +object Test extends Application { + trait AddRemove { + type TNode <: NodeImpl; + trait NodeImpl; + + object removing { + type TNode = AddRemove.this.TNode; + def printNode(node: TNode, f: TNode => String) = Console.println(f(node)) + } + } + + class Linked extends AddRemove { + type TNode = Node // can also directly write `class Node extends super.NodeImpl' -- doesn't change the bug + class Node extends super.NodeImpl { override def toString = "LinkedNode" } + + removing.printNode(new Node, (x: removing.TNode) => x.toString) // make inference explicit, doesn't affect the bug + } + + new Linked +} \ No newline at end of file -- cgit v1.2.3
