Bug 79351 – [Shadow DOM] Make Node::showTreeForThis dump multiple shadow roots.

• Component: DOM
• Status: RESOLVED FIXED

[Hayato Ito]

Make Node::showTreeForThis (and showTreeForThisAcrossFrame) dump multiple shadow roots.
The current implementation dumps only the first shadow root. Which is not useful for debugging an element which has multiple shadow roots.

The sample output is here:

*			DIV	0x7fffe377c080 CLASS=shadowHost
				#shadow-root	0x7fffe4221400
					#shadow-root	0x7fffe3793000
						DIV	0x7fffe3794300 CLASS=class1
							DIV	0x7fffe3794180 CLASS=class3
							SHADOW	0x7fffe3794200 CLASS=shadow
							DIV	0x7fffe3794280 CLASS=class3
					DIV	0x7fffe377c200 CLASS=class1
						DIV	0x7fffe377c100 CLASS=class2
						CONTENT	0x7fffe37a45a0 CLASS=content
						DIV	0x7fffe377c180 CLASS=class2
				DIV	0x7fffe3812880 CLASS=lightChild1
				DIV	0x7fffe377c000 CLASS=lightChild2


The younger shadowRoot is displayed as a child of olderShadowRoot, which fits my mental model.
It also matchs the relation between shadowHost and shadowRoot. A child is always rendered earlier than the parent.

I wrongly committed the parts of this patch with http://trac.webkit.org/changeset/108605.
Which was unintentional.

This patch includes the updated version.

ok. Would love to have something more sophisticated in the future, like an ASCII-drawn tree stack, but this is totally fine.

Let me update the ChageLog, which misses a reviewer line.
