Subject: window.open should prepare for seamless navigation by using findFrameForNavigation
X-Git-Tag: 070512121124~7111
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b46fdeff0ac0d3ba194add11b605bb7942c90213;p=profile%2Fivi%2Fwebkit-efl.git

window.open should prepare for seamless navigation by using findFrameForNavigation
https://bugs.webkit.org/show_bug.cgi?id=83835

Reviewed by Ryosuke Niwa.

Before this patch, window.open called FrameTree::find and
Document::canNavigate separately.  This patch refactors the code to
call FrameLoader::findFrameForNavigation, which does both.  This
refactoring prepares window.open to understand seamless navigation,
which will happen in findFrameForNavigation.

This patch should have no behavior change today, but once we merge the
seamless branch, this change will be tested by
https://github.com/eseidel/webkit/blob/seamless/LayoutTests/fast/frames/seamless/seamless-window-open.html

See https://github.com/eseidel/webkit/commit/a0d8b7defbb63047912aefbc8e22bca4f0638c37 for context.
