Bug 156108 – [GTK] Custom elements specification.

• Status: RESOLVED
• Resolution: FIXED
• Component: DOM

[Carlos Alberto Lopez Perez]

There is an ongoing implementation of the custom elements API <https://www.w3.org/TR/custom-elements/> on bug 154907.

This bug is for tracking the implementation of the GTK+ specific parts of this specification (if any), for enabling it and for testing it.

I don't think there will be any port specific code needed other than port specific WebKit API to be exposed if any.

On the GTK+ port currently running the tests inside fast/custom-elements currently gives the following:

Regressions: Unexpected text-only failures (11)
  fast/custom-elements/Document-createElement.html [ Failure ]

On r195087 <http://trac.webkit.org/r195087> you set the the fast/custom-elements as expected to fail for all ports but the Mac one. However, some tests were timing out (instead of failing), this caused unexpected failures on the bots.

So I skipped completely the fast/custom-elements tests on r198993 <http://trac.webkit.org/r198993> for the GTK+ port linking to this bug.

The EFL port did something similar in r198779 <http://trac.webkit.org/r198779>

[Michael Catanzaro]

All tests added in r206838 are failing. I'll skip these too.

Is there a build or runtime flag for custom elements?

I'm enabling this feature everywhere on https://bugs.webkit.org/show_bug.cgi?id=164242.
