(The adopt() method also more + closely matches that of WebCore::StringImpl). + + Also, UString::createUninitialized() and UStringImpl::createUninitialized() have incompatible + behaviours, in that the UString form sets the provided UChar* to a null or non-null value to + indicate success or failure, but UStringImpl uses the returned PassRefPtr<UStringImpl> to + indicate when allocation has failed (potentially leaving the output Char* uninitialized). + This is also incompatible with WebCore::StringImpl's behaviour, in that + StringImpl::createUninitialized() will CRASH() if unable to allocate. Some uses of + createUninitialized() in JSC are unsafe, since they do not test the result for null. + UStringImpl's indication is preferable, since we may want a successful call to set the result + buffer to 0 (specifically, StringImpl returns 0 for the buffer where createUninitialized() + returns the empty string, which seems reasonable to catch bugs early). UString's method + cannot support UStringImpl's behaviour directly, since it returns an object rather than a + pointer. + - remove UString::createUninitialized(), replace with calls to UStringImpl::createUninitialized() + - create a UStringImpl::tryCreateUninitialized() form UStringImpl::createUninitialized(), + with current behaviour, make createUninitialized() crash on failure to allocate. + - make cases in JSC that do not check the result call createUninitialized(), and cases that do + check call tryCreateUninitialized(). + + Rename computedHash() to existingHash(), to bring this in line wih WebCore::StringImpl. + + * API/JSClassRef.cpp: + (OpaqueJSClassContextData::OpaqueJSClassContextData): + * JavaScriptCore.exp: + * runtime/ArrayPrototype.cpp: + (JSC::arrayProtoFuncToString): + * runtime/Identifier.cpp: + (JSC::CStringTranslator::translate): + (JSC::UCharBufferTranslator::translate): + * runtime/JSString.cpp: + (JSC::JSString::resolveRope): + * runtime/Lookup.cpp: + (JSC::HashTable::createTable): + * runtime/Lookup.h: + (JSC::HashTable::entry): + * runtime/StringBuilder.h: + (JSC::StringBuilder::release): + * runtime/StringConstructor.cpp: + (JSC::stringFromCharCodeSlowCase): + * runtime/StringPrototype.cpp: + (JSC::substituteBackreferencesSlow): + (JSC::stringProtoFuncToLowerCase): + (JSC::stringProtoFuncToUpperCase): + (JSC::stringProtoFuncFontsize): + (JSC::stringProtoFuncLink): + * runtime/Structure.cpp: + (JSC::Structure::despecifyDictionaryFunction): + (JSC::Structure::get): + (JSC::Structure::despecifyFunction): + (JSC::Structure::put): + (JSC::Structure::remove): + (JSC::Structure::insertIntoPropertyMapHashTable): + (JSC::Structure::checkConsistency): + * runtime/Structure.h: + (JSC::Structure::get): + * runtime/StructureTransitionTable.h: + (JSC::StructureTransitionTableHash::hash): + * runtime/UString.cpp: + (JSC::createRep): + (JSC::UString::UString): + (JSC::UString::spliceSubstringsWithSeparators): + (JSC::UString::replaceRange): + (JSC::UString::operator=): + * runtime/UString.h: + (JSC::UString::adopt): + (JSC::IdentifierRepHash::hash): + (JSC::makeString): + * runtime/UStringImpl.h: + (JSC::UStringImpl::adopt): + (JSC::UStringImpl::create): + (JSC::UStringImpl::createUninitialized): + (JSC::UStringImpl::tryCreateUninitialized): + (JSC::UStringImpl::existingHash): + +2010-01-13 Kent Hansen <kent.hansen@nokia.com> + + Reviewed by Oliver Hunt. + + JSON.stringify and JSON.parse needlessly process properties in the prototype chain + https://bugs.webkit.org/show_bug.cgi?id=33053 + + * runtime/JSONObject.cpp: + (JSC::Stringifier::Holder::appendNextProperty): + (JSC::Walker::walk): + +2010-01-13 Gavin Barraclough <barraclough@apple.com> + + Reviewed by NOBODY (buildfix). + + * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def: + +2010-01-13 Alexey Proskuryakov <ap@apple.com> + + Reviewed by Darin Adler. + + https://bugs.webkit.org/show_bug.cgi?id=33641 + Assertion failure in Lexer.cpp if input stream ends while in string escape + + Test: fast/js/end-in-string-escape.html + + * parser/Lexer.cpp: (JSC::Lexer::lex): Bail out quickly on end of stream, not giving the + assertion a chance to fire. + +2010-01-13 Gavin Barraclough <barraclough@apple.com> + + Reviewed by NOBODY (buildfix). + + * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def: + +2010-01-13 Gavin Barraclough <barraclough@apple.com> + + Rubber stamped by Sam Weinig & Darin Adler. + + Three quick fixes to UStringImpl. + - The destroy() method can be switched back to a normal destructor; since we've switched + the way we protect static strings to be using an odd ref-count the destroy() won't abort. + - The cost() calculation logic was wrong.
