WebKit Contributor Meeting 2012 - LayoutTestController Functions That We Want to Move to Internals

Guidelines:

• Everything that makes many ports skip tests should be considered.
  
• Functions that use internal WebKit methods whose only purpose is to support DRT (as opposed as providing public API) should be strongly considered.
  
• Functions that rely upon a significant amount of WebKit code may be best to remain in LayoutTestController, so that this code would be tested.

We'll file bugs in Tools/Tests component as we go, too.

• counterValueForElementById

Mac DRT has a StorageTrackerDelegate to test WebStorageManager, but no other port seems to have this. Related LayoutTestController functions that are implemented in Mac only are:

• deleteAllLocalStorage
• syncLocalStorage
• observeStorageTrackerNotifications
• deleteLocalStorageForOrigin
• localStorageDiskUsageForOrigin
• originsWithLocalStorage

(morrita: This set of APIs looks a part of real Mac WebKit API. See: ​http://wkb.ug/51878)

Animation Controller DRT APIs that can be ported to internals as these APIs depend on core frame pointer. Currently implemented for - Chromium, Gtk, Efl, Qt, Mac, Win

• pauseAnimationAtTimeOnElementWithId
• pauseTransitionAtTimeOnElementWithId
• numberOfActiveAnimations
• suspendAnimations
• resumeAnimations

---

• setTextDirection - calls a WebKit API on Mac and Chromium, but it seems that other than passing it through to WebCore, it doesn't do much else

---

The following methods are not implemented in all ports and should be considered for move to Internals:

• computedStyleIncludingVisitedInfo
• dispatchPendingLoadRequests
• displayInvalidatedRegion

---

• printToPDF - No Implementation, no usage, No Testcase.
