From c490f801b063a0837501feab3d12b73d71f46312 Mon Sep 17 00:00:00 2001 From: "jvanverth@google.com" Date: Mon, 4 Mar 2013 13:56:38 +0000 Subject: Change random number generator for 'tests' to SkMWCRandom. Also removes some unused headers and fixes a couple of bugs exposed by changing the random number generator: First, the function SkMatrix::getMaxStretch() had an error where it was testing the square of a number against near-zero. This led to it occasionally taking a cheaper but imprecise path for computing the eigenvalues of the matrix. It's been replaced with a check against the square of SK_ScalarNearlyZero. The second case was a failure in ClipStackTest, where it hit the rare case of a practically empty clip stack (it has a single Union) and we set a tight bounds. The bounds rect doesn't get set by GrReducedClip::ReduceClipStack() in this case, so when it clips the reduced stack it's clipping against garbage, and the resulting regions don't match. The solution is to initialize the tightBounds rect. git-svn-id: http://skia.googlecode.com/svn/trunk@7952 2bbb7eff-a529-9590-31e7-b0007b416f81 --- tests/UtilsTest.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tests/UtilsTest.cpp') diff --git a/tests/UtilsTest.cpp b/tests/UtilsTest.cpp index 7f27f7e78e..bdabb57de0 100644 --- a/tests/UtilsTest.cpp +++ b/tests/UtilsTest.cpp @@ -54,7 +54,7 @@ static void test_autounref(skiatest::Reporter* reporter) { static void test_search(skiatest::Reporter* reporter) { int i, array[kSEARCH_COUNT]; - SkRandom rand; + SkMWCRandom rand; for (i = 0; i < kSEARCH_COUNT; i++) { array[i] = rand.nextS(); -- cgit v1.2.3
