Bug 1019191 part 21. Change xpc_qsUnwrapArgImpl and UnwrapArg to take a HandleObject, not a HandleValue. r=peterv

Bug 1019191 part 20. Replace the getWrapper/castNative stuff in XPCQuickStubs with what I believe is a single function call that's equivalent to it, since the tearoff bit was dead code anyway due to never resetting clasp. r=peterv,bholley

Bug 1019191 part 19. Change GlobalObject::GetAsSupports to not rely on UnwrapArg producing an nsISupports for non-reflectors. r=peterv

Bug 1019191 part 18. Remove the unused tearoff bits in quickstub unwrapping. r=peterv

Bug 1019191 part 17. Make some of the remaining quickstub unwrap methods static. r=peterv Note that we know that we always call UnwrapArg with an object, so xpc_qsUnwrapArgImpl knows v is always an object.

Bug 1019191 part 16. Remove nsDOMQS.h. r=peterv

Bug 1019191 part 15. Remove now-dead DOMCI_DATA bits. r=peterv

Bug 1019191 part 14. Remove the now-unused HasBitInInterfacesBitmap and all the interfaces bitmap machinery that ends up unused as a result. r=peterv

Bug 1019191 part 13. Remove the now-unused castNativeArgFromWrapper and castNativeFromWrapper functions. r=peterv

Bug 1019191 part 12. Eliminate some unused UnwrapArg specializations. r=peterv The following command: grep -Ir "UnwrapArg<" $srcdir/* $objdir/dom/bindings/ | sed 's/^[^<]*<//' | sed 's/>.*//' | sort -u (with $srcdir and $objdir replaced by the relevant paths) produces this list: ${type} _clazz _interface imgINotificationObserver imgIRequest mozilla::dom::EventTarget mozilla::dom::IndirectlyImplementedInterface mozilla::dom::TestExternalInterface nsGenericHTMLElement nsIBrowserDOMWindow nsIChannel nsIDOMCSSRule nsIDOMDataChannel nsIDOMMozMmsMessage nsIDOMMozSmsMessage nsIDOMMozWakeLockListener nsIDOMWindow nsIDOMXPathNSResolver nsIFile nsIFrameRequestCallback nsIInputStream nsIInputStreamCallback nsIJSID nsIMenuBuilder nsIObserver nsIOutputStream nsIPrincipal nsISelectionListener nsISupports nsITreeView nsIURI The ${type} bit is part of codegen. The _clazz and _interface bits are the macros in js/xpconnect/src/nsDOMQS.h that are defining UnwrapArg methods. The nsGenericHTMLElement is only used in xpc_qsUnwrapArg_HTMLElement. Inspection of the above list indicates that none of the classes used with DEFINE_UNWRAP_CAST_HTML are in it, so all those specializations of UnwrapArg, and the xpc_qsUnwrapArg_HTMLElement method they call, are dead code. Moreover, almost all the specializations set up by DEFINE_UNWRAP_CAST are dead code as well; the only exception is the one for mozilla::dom::EventTarget. But since we no longer use Web IDL quickstubs for EventTarget, that one is only used in a few places for method arguments, and none of those should have our one remaining webidl event target passed to them. So it's safe to remove that specialization as well.

Bug 1019191 part 11. Get rid of the now-unused xpc_qsUnwrapArg. r=peterv

Bug 1019191 part 10. Stop using xpc_qsUnwrapArg directly in BindingUtils. r=peterv

Bug 1019191 part 9. Remove now-dead JS-to-C++ quickstub conversion functions. r=peterv

Bug 1019191 part 8. Stop using xpc_qsACString in XPConnect. r=bholley

Bug 1019191 part 7. Remove various dead-code throwing functions. r=peterv

Bug 1019191 part 6. Remove dead code for setting up quickstubs on a prototype from XPCQuickStubs.h/cpp. r=peterv

Bug 1019191 part 5. Remove the one remaining quickstub we have and all quickstub codegen. r=peterv

Bug 1019191 part 4. Remove the now-dead xpc_qsThrowGetterSetterFailed and xpc_qsThrowBadSetterValue functions. r=peterv

Bug 1019191 part 3. Remove calls to the empty DOM_MarkInterfaces/DOM_ClearInterfaces/DOM_InitInterfaces functions and the functions themselves. r=peterv

Bug 1019191 part 2. Remove WebIDL quickstubs for EventTarget, since the only remaining xpconnect EventTargets with classinfo are globals, and we never call PostCreatePrototype on globals. r=peterv
