Bug 174695 – Drop legacy SVGException type

• Component: SVG
• Status: RESOLVED FIXED

[Chris Dumez]

Drop legacy SVGException type. It is not longer part of the specification (replaced by DOMException). Both Firefox and Chrome no longer expose it.

r=me assuming you can get everything to compile and all the tests to pass; not sure why there are EWS failures

Is this something you will be removing in a future patch?

Why RefPtr instead of Ref? The IDL file does not indicate a nullable return type. I think this should use Ref for the return type. Probably just need to add some releaseNonNull() to implementation in a few places.

Ditto.

> Source/WebCore/svg/SVGPathSegList.h:81
> +    ExceptionOr<RefPtr<SVGPathSeg>> insertItemBefore(Ref<SVGPathSeg>&& newItem, unsigned index)

Ditto.

> Source/WebCore/svg/SVGPathSegList.h:86
> +    ExceptionOr<RefPtr<SVGPathSeg>> replaceItem(Ref<SVGPathSeg>&&, unsigned index);

Ditto.

> Source/WebCore/svg/SVGPathSegList.h:88
> +    ExceptionOr<RefPtr<SVGPathSeg>> removeItem(unsigned index);

Ditto.

> Source/WebCore/svg/SVGPathSegList.h:90
> +    ExceptionOr<RefPtr<SVGPathSeg>> appendItem(Ref<SVGPathSeg>&& newItem)

Ditto.

Will see if this is a small enough change to drop in this patch. But yes, follow-up clean up is planned.

Dropped in the next iteration.

I can look into it for a follow up. This is a larger change because it requires modifying SVGListProperty and all its subclasses.

I think I would have called this “unwrappedException” or "underlyingException".
