- OverflowChangedTracker::AddFrame now accepts an enumerated type parameter to
indicate if the overflow areas of children have changed (CHILDREN_CHANGED),
the overflow areas of the children have changed and the parent have changed
(CHILDREN_AND_PARENT_CHANGED), or if only 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.
This patch was mostly generated with the following command:
find . -name "*.h" -o -name "*.cpp" | xargs sed -e '/WrapObject(JSContext/ {; N; s/\(WrapObject(JSContext *\* *a\{0,1\}[Cc]x\),\n\{0,1\} *JS::Handle<JSObject\*> a\{0,1\}[sS]cope/\1/ ; }' -i ""
and then reverting the changes that made to
dom/bindings/BindingUtils.h, since those WrapObject methods are not
the ones we're trying to change here, plus a bunch of manual fixups
for cases that this command did not catch (including all the callsites
of WrapObject()).

plus a few manual fixes to dom/bindings/Codegen.py, js/xpconnect/src/event_impl_gen.py, and a few C++ files that were not caught in the search-and-replace above.

Tests for animation list handling on the compositor thread. Some checks are
currently marked todo_is because they depend on Bug 980769 in order to pass.
This patch takes the compareTransform utility methods and makes them more
generic so they can be used for testing opacity too (the other property
currently animated on the compositor thread).
The naming omta_is and omta_is_approx is intended to mirror is and is_approx in
test_animations.html.
This patch adds an additional mochitest for specifically targetting CSS
Animations that run on the compositor thread. The content of the test mimicks
test_animations.html but using properties whose animations are expected to run
on the compositor thread.
Since off-main thread animation (OMTA) is not available on all platforms we
define a common wrapper function that runs OMTA tests only when available. This
patch further performs an internal check of basic OMTA operation so that
only a single error is produced if OMTA is unexpectedly unavailable.
Typical usage is:
SimpleTest.waitForExplicitFinish();
runOMTATest(function() {
... test code ...
SimpleTest.finish();
},
SimpleTest.finish);
This can be easily wrapped with promises if needed but does not require using
promises.
The calls to waitForExplicitFinish and finish are not performed automatically
since this function may be integrated with test suites that do other work
outside the call to runOMTATest.
Two comments in AnimationCommon.h refer to 'mFlushCount' which was presumably
the old name for mAnimationGeneration. Also, one comment says
nsCSSFrameConstructor tracks this. This patch adjusts the comments to refer
to mAnimationGeneration and RestyleManager.
(The reference to nsTransitionManager::UpdateAllThrottleStyles() is still valid
since there is useful documentation accompanying that method despite the fact
that the relevant code is mostly contained in AnimationCommon.h since bug
914847. Eventually we will unify the structures of transitions and
animations to the the point that we can replace the
IMPL_UPDATE_ALL_THROTTLED_STYLES_INTERNAL macro in AnimationCommon.h with an
actual method. At that point we can move the documentation accompanying
nsTransitionManager::UpdateAllThrottleStyles and its references to
AnimationCommon.)
We need a basic representation of animations from which we can derive subclasses
to represent specific cases such as transitions. For now we will retrofit
ElementAnimation for that purpose hence renaming it to StyleAnimation.
This patch removes the "using namespace mozilla::layers" line from
AnimationCommon.cpp since the unified build system concatenates several files
together before compiling making using declarations like this leak into other
files potentially creating ambiguities. Previously, when we were calling
ElementAnimation, 'Animation', there were ambiguities between
mozilla::layers::Animation and this new 'Animation' class. In general, it is
probably a good idea to limit the scope of these using declarations so I've kept
that change.
This patch relocates ElementAnimation from nsAnimationManager.{h,cpp} to
AnimationCommon.{h,cpp} and in the process moves it into the mozilla::css
namespace.
ElementAnimation::HasAnimationOfProperty doesn't seem to be overridden anywhere.
I suspect it was a copy-paste mistake because the methods of the same name on
ElementAnimations, ElementTransitions, and CommonElementAnimationData are
virtual.
Now that ElementTransitionProperty inherits from ElementAnimation,
ElementTransitions::HasAnimationOfProperty can re-use
ElementAnimation::HasAnimationOfProperty in its definition of
ElementTransitions::HasAnimationOfProperty.
Similarly, in nsDisplayList::AddAnimationsAndTransitionsToLayer we can use this
method rather than drilling down to the appropriate segment by hand.
