https://bugs.webkit.org/show_bug.cgi?id=25477 Reviewed by Oliver Hunt. Source/JavaScriptCore: We're just calling get() to get properties, which is converting missing properties to undefined. Hole values should be retained, and moved to the end of the array. * runtime/ArrayPrototype.cpp: (JSC::getOrHole): - Helper function, returns JSValue() instead of undefined for missing properties. (JSC::arrayProtoFuncSort): - Implemented per 15.4.4.11, see comments above. LayoutTests: Added test cases. * fast/js/array-sort-sparse-expected.txt: Added. * fast/js/array-sort-sparse.html: Added. * fast/js/script-tests/array-sort-sparse.js: Added. (testSort): git-svn-id: http://svn.webkit.org/repository/webkit/trunk@129317 268f45cc-cd09-0410-ab3c-d52691b4dbfc
