407105 - 2d.line.join.parallel fails on Mac but passes on Windows/Linux

Status: RESOLVED FIXED

(Core :: Graphics, defect, P3)

Description

[Boris Zbarsky [:bzbarsky]]

The following tests pass on Windows/Linux but no Mac:

  content/canvas/test/test_2d.line.cap.zerobezier.round.html
  content/canvas/test/test_2d.line.join.parallel.html
  content/canvas/test/test_2d.strokeRect.zero.5.html

Not sure whether they should pass or fail (canvas spec does not define it), but the platform difference in behavior seems to be a cairo bug or set of bugs.  We should probably push this upstream, but I'm not sure how to create a simple-ish cairo testcase here.

[Benoit Jacob [:bjacob] (mostly away)]

content/canvas/test/test_2d.line.cap.zerobezier.round.html doesn't exist anymore.

Can someone check if the others still fail on Mac?

http://w3c-test.org:82/2dcontext/line-styles/2d.line.join.parallel.html passes for me on Mac, as does the test in dom/canvas/tests if I run it.

Never mind, this still fails on 10.6 it looks like (https://treeherder.mozilla.org/ui/#/jobs?repo=try&revision=b139a6cd24a9)

Direct links do not work, and we diligently track w3c test-suite now.
