Message:

Implement String.prototype.replaceAll
​https://bugs.webkit.org/show_bug.cgi?id=202471

Reviewed by Yusuke Suzuki.

JSTests:

  • stress/string-replaceall.js: Added.

Source/JavaScriptCore:

Implement the stage 3 proposal here:
​https://github.com/tc39/proposal-string-replaceall

String.prototype.replaceAll is the same as String.prototype.replace, except:

  1. When the first argument is a string, all instances of the search string are replaced.
  2. When the first argument is a non-global regular expression, a TypeError is thrown.
  • builtins/BuiltinNames.h:
  • builtins/StringPrototype.js:

(replaceAll): Added.

  • runtime/StringPrototype.cpp:

(JSC::StringPrototype::finishCreation):
(JSC::jsSpliceSubstringsWithSeparators): Add early out for single-replacement case.
(JSC::replaceUsingStringSearch): Add global replacement logic, following replaceUsingRegExpSearch.
(JSC::replace):
(JSC::stringProtoFuncReplaceUsingStringSearch):
(JSC::stringProtoFuncReplaceAllUsingStringSearch): Added.

Source/WTF:

  • wtf/text/StringCommon.h:

(WTF::findCommon):
Fix logic: "start > length" early out should come before "empty search string" early out.

LayoutTests:

  • js/Object-getOwnPropertyNames-expected.txt:
  • js/script-tests/Object-getOwnPropertyNames.js:

Grrr, why is this a layout test...
