Bug 63011 – IDL generator should throw TypeError instead of SyntaxError on not enough arguments

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Mark Pilgrim (Google)]

As per http://krijnhoetmer.nl/irc-logs/whatwg/20110618#l-269 , WebIDL mandates that we throw TypeError when a function is called with too few required arguments. WebKit currently throws SyntaxError. This patch rectifies that, as well as fixing the ~20 tests that rely on the old behavior.

NOTE: there are 2 image-based SVG LayoutTests that need rebaselining after this patch lands. This patch does not change visible behavior of SVG; the images just happened to capture the unrelated text "SyntaxError: not enough arguments" (which is now "TypeError: not enough arguments"). The tests in question are

svg/dom/SVGNumberList-basics.xhtml
svg/dom/SVGStringList-basics.xhtml

We should coordinate landing with the gardner due to the image rebaselines.  Maybe ping the gardener on #webkit?
