ES6: Should not allow duplicate basic __proto__ properties in Object Literals https://bugs.webkit.org/show_bug.cgi?id=145138 Patch by Joseph Pecoraro <pecoraro@apple.com> on 2015-05-20 Reviewed by Darin Adler. Source/JavaScriptCore: Implement ES6 Annex B.3.1, which disallows duplicate basic __proto__ properties in object literals. This doesn't affect computed properties, shorthand properties, or getters/setters all of which avoid setting the actual prototype of the object anyway. * interpreter/Interpreter.cpp: (JSC::eval): Remove out of date comment. Duplicate property names are allowed now in ES6, they were not in ES5 strict mode. * parser/ASTBuilder.h: (JSC::ASTBuilder::getName): (JSC::ASTBuilder::getType): * parser/SyntaxChecker.h: (JSC::SyntaxChecker::getName): Add back getName to get the property name depending on the tree builder. Also tighten up the parameter types. * runtime/LiteralParser.cpp: (JSC::LiteralParser<CharType>::parse): In quick JSON literal parsing for eval, we actually need to evaluate the __proto__ property assignment, instead of just building up a list of direct properties. Only do this when not doing a strict JSON parse. * parser/Nodes.h: Add "Shorthand" to the list of PropertyNode types to allow it to be distinguished without relying on other information. * parser/Parser.h: * parser/Parser.cpp: (JSC::Parser<LexerType>::parseProperty): Add the Shorthand type when parsing a shorthand property. (JSC::Parser<LexerType>::shouldCheckPropertyForUnderscoreProtoDuplicate): (JSC::Parser<LexerType>::parseObjectLiteral): (JSC::Parser<LexerType>::parseStrictObjectLiteral): Check for duplicate __proto__ properties, and throw a SyntaxError if that was the case. LayoutTests: * js/dom/JSON-parse-expected.txt: * js/resources/JSON-parse.js: Update expected results for JSON parsing using eval() versus JSON.parse. In eval, an object literal with a "__proto__" property modifies the prototype. In JSON.parse, all properties are direct/own properties, no matter their name, so "__proto__" does not get special treatment. * js/eval-json-proto-expected.txt: Added. * js/eval-json-proto.html: Added. * js/script-tests/eval-json-proto.js: Added. Direct test for LiteralParser behavior, in both eval and JSON.parse. * js/object-literal-duplicate-properties-expected.txt: * js/script-tests/object-literal-duplicate-properties.js: (runProtoTestShouldThrow): (runProtoTestShouldNotThrow): Test for all cases of acceptable and unacceptable __proto__ duplicate properties in literals.

This test case checks different JSON literal constructions and ensures they handle __proto__ as expected.
On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
PASS ({__proto__:[]}) instanceof Array is true
PASS evalResult instanceof Array is true
PASS jsonParseResult instanceof Array is false
PASS successfullyParsed is true
TEST COMPLETE
