Bug 77938

Created attachment 126005 [details] Patch

Zimmermann, I'm now implementing "multiple shadow subtrees", which is described in https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html When "multiple shadow subtrees" is supported, a user can append a shadow root into any elements. SVG elements are not exceptional. So if a user adds a new shadow root into 'tref' element before tref adds shadow root by itself, a problem may happen. So I would like to ensure that a shadow root is created before user can add a new shadow root into this element. Do you think a problem happens if a shadow root is added in a construction phase? If not, I would like to proceed this change. If it does, we have to think another solution.

Patch looks good in general. > Source/WebCore/ChangeLog:9 > + SVGTRefElement creates a shadow root dynamically. This will cause a problem to support > + multiple shadow subtrees. So it should be created in a constructor phase. > + > + Reviewed by NOBODY (OOPS!). These blocks should be swapped. Can you include a testcase that shows this problem? Otherwise this will break again in future. > Source/WebCore/svg/SVGTRefElement.cpp:61 > - return adoptRef(new SVGTRefElement(tagName, document)); > + RefPtr<SVGTRefElement> elem = adoptRef(new SVGTRefElement(tagName, document)); > + elem->createShadowSubtree(); > + return elem.release(); s/elem/element/ - no abbreviations please.

I'll resubmit this after Bug 77935 is landed. I'm now using it...

All reviewed patches have been landed. Closing bug.

This bug is still mentioned in http://code.google.com/searchframe#OAMlx_jo-ck/src/third_party/WebKit/Source/WebCore/dom/ShadowRoot.cpp&exact_package=chromium&q=allowsAuthorShadowRoot&type=cs&l=75. Should we remove the check now?
