27b28b1c13 Backed out changeset 7be71c699b85 (bug 984226) for crashtest asserts. 2014-04-08 15:31:45 -04:00
Kearwood (Kip) Gilbert
ebcffdc9e3 Bug 984226 - Add parameter to OverflowChangedTracker::AddFrame to distingush between frames that need nsIFrame::UpdateOverflow called and frames that only have a transform that has changed. r=dbaron 
- OverflowChangedTracker::AddFrame now accepts an enumerated type parameter to
  indicate if the overflow areas of children have changed (CHILDREN_CHANGED) or
  if the transform has changed (TRANSFORM_CHANGED).
- OverflowChangedTracker::Flush no longer falls back to calling
  nsIFrame::UpdateOverflow when a frame lacks a PreTransformOverflowAreas
  property.
- Added an additional change hint, nsChangeHint_ChildrenOnlyTransform, which
  results in TRANSFORM_CHANGED being passed in to
  OverflowChangedTracker::AddFrame.
- In nsIFrame::FinishAndStoreOverflow, the passed in overflow is now stored as
  the InitialTransformProperty for elements that are IsTransformed().
- Partially corrected Bug 926155, by only calling
  OverflowChangedTracker::AddFrame on parents of the sticky element during
  StickyScrollContainer::UpdatePositions, using CHILDREN_CHANGED.

c857e1a9dd Bug 898888: Transition manager should use SetStyleContext rather than SetStyleContextWithoutNotification. r=nrc 
While debugging bug 858937 I noticed that the transition manager was
calling nsIFrame::SetStyleContextWithoutNotification rather than
nsIFrame::SetStyleContext.  SetStyleContextWithoutNotification should
only be used for things that aren't really style changes, but are
instead changes we make during frame construction before things are
really initialized.  Anything that's really a dynamic style change, as
these are, should use SetStyleContext.

I realize I said the opposite in bug 780692 comment 186, and bz said the
same in bug 780692 comment 204, which is why this is the state that it
is.

796a090f34 Bug 866785 - Move repeated nsIFrame::List implementations code to a new method, ListGeneric, for re-use. Cleanup and improve the code a bit. r=roc 
Specifically:
* move all the frame dump methods to nsIFrame. Especially nsFrame::ListTag
  was annoying, often requiring a cast to nsFrame*.
* print common values in the same order for all types of frames
* print fluid continuations as "next-in-flow=%p" and non-fluid as
  "next-continuation=%p" (as before)
* print the style-context more compactly, e.g.
  "[sc=0x7faa6b60e0a0] pst=:first-line" becomes
  "[sc=0x7faa6b60e0a0:first-line]"
* suppress printing visual/scroll-overflow rects when they are identical
  to mRect and do the same for nsLineBox::List where it was especially
  hard to see which lines actually had real overflow
* fix a bug that printed the child list name at the far right when the
  principal list was empty (making it hard to see)
* print the address of child lists (other than the principal list) to
  help debug frame list property bugs
* s/NS_IMETHODIMP/void/

7cbe6380ff Bug 841192. Part 14: Convert all usage of nsDisplayClip(RoundedRect) to use DisplayListClipState/DisplayItemClip. r=mattwoodrow 
This patch does several things. Sorry.

In BuildDisplayList implementations, instead of wrapping display items in nsDisplayClip, we
push clip state onto the nsDisplayListBuilder and give the display items an
explicit clip when they're created.

In FrameLayerBuilder, we use the explicit clips we find on display items instead of
computing our own.

We remove nsDisplayClip and everything that depends on it.

We remove ExplodeAnonymousChildLists. With nsDisplayClip gone, and
nsDisplayOptionEventGrabber removed in a previous patch, there are no
anonymous child lists.

nsDisplayItem::TryMerge implementations need to make sure they have the same
clip before being merged.

I ripped out the part of PruneDisplayListForExtraPage that adjusts clip rects.
As far as I can tell, it isn't actually necessary.
