Bug 44797 – fullscreen javascript bindings not implemented for v8

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Tony Chang]

These were added http://trac.webkit.org/changeset/66251, but need to be implemented for V8.

Of course, the related layout tests are also failing.

cc-ing dglazkov to triage.  I'm going to add to test_expectations for now.

[David Dorwin]

With this patch and another small one to Chromium, Chromium supports the WebKit Full Screen APIs and passes all the layout tests when --enable-fullscreen is specified. The layout tests remain disabled until we make this the default.

As mentioned in the patch description, the fullscreen rendering still needs to be implemented.

I only reviewed the WebKit/chromium changes.

LGTM for this WebKit API change.

Seems reasonable.

we have a notImplemented() call which may be more useful than a FIXME.

This doesn't compile if ENABLE_FULLSCREEN_API is not set to true (which means it's broken on the canaries currently since they use features_overrides.gypi).  At a minimum you need a feature guard inside WebSettingsImpl::setFullScreenEnabled(bool enabled).

[James Robinson]

Reverted r79584 for reason:

Fixed the build break when ENABLE_FULLSCREEN_API is not 1 and used notImplemented() as Eric suggested.

Looks like you'll get an unused variable warning in WebSettingsImpl::setFullScreenEnabled(bool enabled) if ENABLE(FULLSCREEN_API) is false, which is a compile error on at least some configs.  We have an UNUSED_PARAM() macro for such things.

Added UNUSED_PARAM().

Thanks for catching that. The Mac Chromium config is apparently not one of them.

I don't think this is a real failure after all.  It's failing on build.webkit.org but building fine on build.chromium.org.  We need to investigate what's happening though.

I think a clobber of the WebKit Chromium bots should resolve this. Looking at the build output, Document.cpp was not rebuilt even though the value of ENABLE_FULLSCREEN_API changed in Source/WebKit/chromium/features.gypi. The new value is being picked up in ChromeClientImpl.cpp, causing ChromeClientImpl::exitFullScreenForElement() to be compiled.

The full Chromium build still has ENABLE_FULLSCREEN_API=0 until I check in the corresponding Chromium CL.

The Chromium Win bot is passing now.
