The assertions in nsINode and nsWrapperCache are to eagerly catch failures to override those methods. The classinfo change for XULTreeBuilder is needed because one of those is returned via an nsIXULTemplateBuilder attribute on XULElement. Alternately, I could mark it notflattened in Bindings.conf, but Enn said he prefers this anyway. The change to the QI impl in BindingUtils is needed because when XPConnect converts an IID from C++ to JS it makes is an nsJSID, not an nsJSIID. We've run into this before, sadly. I removed "id" from nsIDOMXULElement because it's already on Element. I suppose I could have left it there, but this seems cleaner. The nsJSIID::HasInstance changes are needed to support XBL-implemented interfaces. Sadly, this does mean that if the underlying object QIs to something but we didn't put those props on the WebIDL we'll end up testing true for instanceof but not exposing the props. I don't see an obviously better way. We should work on killing off uses of "instanceof someinterface". The browser.js change is needed to avoid throwing exceptions during browser-chrome tests that are now getting reported because our swapFrameLoaders is no longer an XPConnect method.

/**
|
|
* Class to store the wrapper for an object. This can only be used with objects
|
|
* that only have one non-security wrapper at a time (for an XPCWrappedNative
|
|
* this is usually ensured by setting an explicit parent in the PreCreate hook
|
|
* for the class).
|
|
*
|
|
* An instance of nsWrapperCache can be gotten from an object that implements
|
|
* a wrapper cache by calling QueryInterface on it. Note that this breaks XPCOM
|
|
* rules a bit (this object doesn't derive from nsISupports).
|
|
*
|
|
* The cache can store objects other than wrappers. We allow wrappers to use a
|
|
* separate JSObject to store their state (mostly expandos). If the wrapper is
|
|
* collected and we want to preserve this state we actually store the state
|
|
* object in the cache.
|
|
*
|
|
* The cache can store 2 types of objects:
|
|
*
|
|
* If WRAPPER_IS_DOM_BINDING is not set (IsDOMBinding() returns false):
|
|
* - a slim wrapper or the JSObject of an XPCWrappedNative wrapper
|
|
*
|
|
* If WRAPPER_IS_DOM_BINDING is set (IsDOMBinding() returns true):
|
|
* - a DOM binding object (regular JS object or proxy)
|
|
*
|
|
* The finalizer for the wrapper clears the cache.
|
|
*
|
|
* A number of the methods are implemented in nsWrapperCacheInlines.h because we
|
|
* have to include some JS headers that don't play nicely with the rest of the
|
|
* codebase. Include nsWrapperCacheInlines.h if you need to call those methods.
