From dd89b006218d76a74d0185392d5e427c0867a33c Mon Sep 17 00:00:00 2001 From: Jason Zaugg Date: Sat, 23 Mar 2013 08:59:51 +0100 Subject: SI-7285 Fix match analysis with nested objects. The fix for SI-6146 introduced `nestedMemberType` to enumerate sealed subtypes based on the (prefixed) type of the scrutinee and the symbols of its sealed subclasses. That method needed to widen `ThisType(modSym)`s to `ModuleTypeRef(modSym)` before calling `asSeenFrom`. However, this could lead to confused in the match analysis, which sees `ModuleTypeRef` as distinct from singleton types on the same modules (after all, they aren't =:=). Spurious warnings ensued. This commit makes two changes: - conditionally re-narrow the result of `asSeenFrom` in `nestedMemberType`. - present `a.b.SomeModule.type` as `SomeModule` in warnings emitted by the pattern matcher. --- test/files/pos/t7285a.flags | 1 + 1 file changed, 1 insertion(+) create mode 100644 test/files/pos/t7285a.flags (limited to 'test/files/pos/t7285a.flags') diff --git a/test/files/pos/t7285a.flags b/test/files/pos/t7285a.flags new file mode 100644 index 0000000000..e8fb65d50c --- /dev/null +++ b/test/files/pos/t7285a.flags @@ -0,0 +1 @@ +-Xfatal-warnings \ No newline at end of file -- cgit v1.2.3
