From c7cc1a803764b4d26dd23d2baf34a27a3a40f682 Mon Sep 17 00:00:00 2001 From: Rex Kerr Date: Sun, 20 Jul 2014 12:36:25 -0700 Subject: SI-8738 Regression in range equality Missed the case of comparing a non-empty range to an empty one. Fixed by checking nonEmpty/isEmpty on other collection. Added a test to verify the behavior. --- test/files/run/t8738.scala | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 test/files/run/t8738.scala (limited to 'test') diff --git a/test/files/run/t8738.scala b/test/files/run/t8738.scala new file mode 100644 index 0000000000..6898301db7 --- /dev/null +++ b/test/files/run/t8738.scala @@ -0,0 +1,16 @@ +object Test { + def check(a: Range, b: Range) = (a == b) == (a.toList == b.toList) + def main(args: Array[String]) { + val lo = -2 to 2 + val hi = lo + val step = List(-6,-2,-1,1,2,6) + for (i <- lo; j <- hi; n <- step; k <- lo; l <- hi; m <- step) { + assert( + check(i until j by n, k until l by m) && + check(i until j by n, k to l by m) && + check(i to j by n, k until l by m) && + check(i to j by n, k to l by m) + ) + } + } +} -- cgit v1.2.3
