PASS if no crash (stack overflow).
Cyclic resources were not detected if the reference had deep containers https://bugs.webkit.org/show_bug.cgi?id=149182 Reviewed by John Honeycutt. Source/WebCore: During our examination of the SVG rendering tree looking for cycles, if a resource pointed to something that had a nested structure, and one of the parent nodes in that structure was a container object without resources itself, we were not looking into the children. Test: svg/custom/pattern-content-cycle-w-resourceless-container.html * rendering/svg/SVGResourcesCycleSolver.cpp: (WebCore::SVGResourcesCycleSolver::resourceContainsCycles): We should still check all children resources, but not exit early if there are none. Instead we should recurse into any children. (WebCore::SVGResourcesCycleSolver::resolveCycles): Changes to some debug code that no longer compiled (it's still off by default, but at least it will work now). LayoutTests: This test was ported from Blink. I believe it originally came from: https://code.google.com/p/chromium/issues/detail?id=351713 * svg/custom/pattern-content-cycle-w-resourceless-container-expected.txt: Added. * svg/custom/pattern-content-cycle-w-resourceless-container.html: Added.
