Ross Kirsling 0250716efb [JSC] Add missing detached buffer errors for DataView ... https://bugs.webkit.org/show_bug.cgi?id=216062 Reviewed by Yusuke Suzuki. JSTests: * stress/detached-buffer-typeerror.js: Add new test. * stress/dataview-jit-neuter.js: * stress/native-constructors-length.js: Update existing tests. * test262/expectations.yaml: Mark 74 test cases as passing. Source/JavaScriptCore: DataView methods are often expected to throw a TypeError if the underlying ArrayBuffer is detached (or neutered, in older terminology) -- this patch adds a slew of missing cases from the following spec section: - https://tc39.es/ecma262/#sec-properties-of-the-dataview-prototype-object At the same time: - get rid of JSDataView::getOwnPropertySlot, which was turning dataViewProtoGetterByte{Length,Offset} into mostly unreachable code and erroneously causing byte{Length,Offset} to have property descriptors - perform some simple cleanup of neighboring error calls / messages - fix value of DataView.length (our only other DataView spec bug) * runtime/JSDataView.cpp: (JSC::JSDataView::create): (JSC::JSDataView::getOwnPropertySlot): Deleted. * runtime/JSDataView.h: * runtime/JSDataViewPrototype.cpp: (JSC::getData): (JSC::setData): (JSC::dataViewProtoGetterByteLength): (JSC::dataViewProtoGetterByteOffset): * runtime/JSGenericTypedArrayViewConstructorInlines.h: (JSC::JSGenericTypedArrayViewConstructor<ViewClass>::finishCreation): LayoutTests: * fast/canvas/webgl/arraybuffer-transfer-of-control.html: * js/dom/constructor-length.html: * js/script-tests/typedarray-constructors.js: * js/typedarray-constructors-expected.txt: * platform/glib/js/dom/constructor-length-expected.txt: * platform/ios/js/dom/constructor-length-expected.txt: * platform/mac/js/dom/constructor-length-expected.txt: * platform/win/js/dom/constructor-length-expected.txt: * platform/wincairo/js/dom/constructor-length-expected.txt: Update tests and expectations.
