From 80fc8b7818205634caa3996b18b2fd156e9aabd8 Mon Sep 17 00:00:00 2001 From: Paul Phillips Date: Wed, 12 Mar 2014 10:54:51 -0700 Subject: SI-8265 Restore 2.10 variance behavior under -Xsource:2.10 Issue deprecation warning under -Xsource:2.10 so time travelers can have an authentic deprecation experience before finding that their unsound code no longer compiles in 2.11. The relevant ticket to the soundness issue is SI-6566. --- test/files/neg/t8265.check | 6 ++++++ test/files/neg/t8265.flags | 1 + test/files/neg/t8265.scala | 1 + 3 files changed, 8 insertions(+) create mode 100644 test/files/neg/t8265.check create mode 100644 test/files/neg/t8265.flags create mode 100644 test/files/neg/t8265.scala (limited to 'test/files/neg') diff --git a/test/files/neg/t8265.check b/test/files/neg/t8265.check new file mode 100644 index 0000000000..7b1db1c4e5 --- /dev/null +++ b/test/files/neg/t8265.check @@ -0,0 +1,6 @@ +t8265.scala:1: warning: Construct depends on unsound variance analysis and will not compile in scala 2.11 and beyond +class Foo[+CC[X]] { type Coll = CC[_] } + ^ +error: No warnings can be incurred under -Xfatal-warnings. +one warning found +one error found diff --git a/test/files/neg/t8265.flags b/test/files/neg/t8265.flags new file mode 100644 index 0000000000..9d7ba7abd8 --- /dev/null +++ b/test/files/neg/t8265.flags @@ -0,0 +1 @@ +-Xsource:2.10 -deprecation -language:higherKinds -Xfatal-warnings diff --git a/test/files/neg/t8265.scala b/test/files/neg/t8265.scala new file mode 100644 index 0000000000..a215903ebc --- /dev/null +++ b/test/files/neg/t8265.scala @@ -0,0 +1 @@ +class Foo[+CC[X]] { type Coll = CC[_] } -- cgit v1.2.3
