- Verify that smooth scroll-behavior is asynchronous.
- Verify that smooth scroll-behavior is triggered by CSSOM-View DOM methods.
- Verify that instant scroll-behavior interrupts smooth scroll-behavior
animation.
- Verify that smooth scroll-behavior is not framerate dependant.
- Verify that smooth scroll-behavior physics simulations used by animations
converge and allow the animation to reach completion.
- CSSOM-View scroll-behavior smooth scroll animations must produce the same
results indendently of frame-rate:
- Reference samples of scroll position for each frame are captured from a
smooth scroll at 120fps for variations in X-Distance, Y-Distance.
- Test samples are captured from an animation with the same parameters at
varying framerates.
- Variance in position at each sampled interval is compared to the 120fps
reference. To pass the test, the position of each test sample must match
the reference position with a tolerance of one test sample frame's range
of motion. This range of motion is calculated by the position delta of
the reference samples one test frame duration before and after.
- The duration of the reference sample animation and the test sample
animation must match within 1 frame to pass the test.
- The simulation driving the animation must converge and stop on the
destination position for the test to pass.

This is the actual fix for the bug. This changes the vertical sizing of
inline ::first-letter frames to work like inlines (and size based on
font metrics), so that the line-height calculation that happens later
will produces the same results as inlines would produce.
In the case we're concerned with of having a text frame child that's
0x0, this changes the inline ::first-letter from from being 0x0 to
having a height that is determined from the font metrics.
There's no need for these calls to be done in the inline ::first-letter
codepath.
In particular, nsLineLayout::ReflowFrame (called a few lines above)
calls SetRect and DidReflow, while nsLineLayout::RelativePositionFrames
(which is called at the end of inline reflow) calls
FinishAndStoreOverflow.
This patch makes no changes other than duplicating the code previously
after the if/else on both branches of the if/else.
The next two patches in this series will completely rewrite the half in
the non-floating (i.e., inline) codepath (the else branch).
This changes this code to do things in the normal way, which is to use a
separate nsHTMLReflowMetrics for each Reflow, rather than (as this code
was) reusing the one for the nsFirstLetterFrame for its text frame
child.
This test fails without the patch series because the border around the
test is too tall, but patch 5 reduces the height of the border in the
test so that it matches the reference.
This matches patch 2, and also fixes an incorrect use of eRestyle_Self
on the parents of pseudo-elements in order to restyle those
pseudo-elements, where it would not previously have been effective.
This should all be temporary, since this code can go away with bug
960465, when animation phases are removed.
This (like patch 1) posts restyles directly to the pseudo-element
content nodes, which is a new thing as of this bug. Previously we'd
have posted eRestyle_Subtree restyles to the pseudo element's real
element (i.e., the parent of the pseudo-element content node).
This changes the way we post animation restyles for ::before and ::after
pseudo-elements with animations on them.
This (like patch 2) posts restyles directly to the pseudo-element
content nodes, which is a new thing.
This isn't needed right now since AddStyleUpdatesTo is currently only
used when updating main-thread-suppressed animations running on the
compositor. However, it will be needed once we depend on
AddStyleUpdatesTo for bug 960465. And it will have an effect now since
AddStyleUpdatesTo actually adds all animations rather than only the ones
that are suppressed from running on the main thread.
This patch stores the animation name on the Animation object rather than its
AnimationPlayer. This is because Animation objects don't have a reference to
their AnimationPlayer but their AnimationEffect needs access to the animation
name.
This patch also adds an accessor for AnimationPlayer to get the name from its
Animation (since players *do* have a reference to their source animation
content).
This patch fixes a regression from
https://hg.mozilla.org/mozilla-central/rev/31695984cfe2 (bug 1025709). That
patch replaced the EnsureStyleRuleFor method on ElementTransitions and
ElementAnimations with a common method in CommonElementAnimationData.
ElementTransitions::EnsureStyleRuleFor would create a new style rule if
there was no style rule (mStyleRule == nullptr) or if the refresh time was
old (mStyleRuleRefreshTime != aRefreshTime).
ElementAnimations::EnsureStyleRuleFor, however, would create a new style rule
only if mStyleRuleRefreshTime was null or old since a null style rule may
still be valid for animations (unlike transitions). If we bail as soon as we
a null style rule we would never update mNeedsRefreshes when the animation
finishes.
The unified version of EnsureStyleRuleFor in CommonElementAnimationData
adopted the behavior from ElementAnimations checking for a null or old
mStyleRuleRefreshTime.
However, nsTransitionManager::StyleContextChanged sets mStyleRule to nullptr
to indicate that we need to generate a new style rule. This means that we
will fail to create a style rule for the transition in some cases.
This patch addresses this by making nsTransitionManager::StyleContextChanged
set mStyleRuleRefreshTime to a null timestamp. Setting mStyleRule to nullptr
is no longer necessary since EnsureStyleRuleFor will do this when necessary
and nsTransitionManager::mStyleRule is only used after calling
EnsureStyleRuleFor.
bug512295-1.html and bug512295-2.html are sending key events which hides
touch caret. Turn off the touch caret preference to fix test cases that
ought to be failed by definition of the touch caret behavior.
There's no need for this method to turn off blinking anymore. Its only
caller already calls SetCaretReadOnly to achieve the same effect. That
means we don't actually need the mIsBlinking flag after all.

A few things got mashed together here:
-- Inline KillTimer/PrimeTimer into their callers.
-- Instead of having to call StopBlinking and StartBlinking together,
change StartBlinking to ResetBlinking and have it set up
the correct blink state and reset the blink cycle.
-- nsCaret::NotifySelectionChange needs a SchedulePaint
-- nsCaret::DrawAtPosition needs a ResetBlinking

This is the core of the whole patch set.
Now GetPaintGeometry/PaintCaret figure out on their own almost all the state
they need every time we paint. So when caret flags change, all we need
to do is SchedulePaint. We don't need to fiddle with mDrawn and most of the
logic in DrawCaret is obsolete. (In fact, it was duplicated by GetGeometry
and friends, and we're removing that duplication.) EraseCaret, CheckCaretState
and UpdateCaretPosition are also obsolete.
We need to have GetPaintGeometry/PaintCaret choose the correct content node
and offset, either getting them from the Selection or using specific data set by
DrawAtPosition. This logic, plus a bit of other code shared between them, is
put into the helper GetFrameAndOffset.

Instead of checking the mysterious mDrawn state (which is evil and will be
removed), let nsCaret::GetPaintGeometry take sole responsibilty for deciding
whether to draw. It takes the nsStyleUserInterface checks. It also needs to
check blink state, which is made possible by separating blink state into
the mIsBlinkOn flag.

This also fixes what appears to be a bug. MustDrawCaret returned true
when mShowDuringSelection is set even if the caret would otherwise be
hidden due a popup showing. That doesn't make sense.

This code is somewhat tricky. nsCaret::ComputeCaretRects was checking to see
if we have a bidi keyboard, and if so, what direction it's set to.
If the direction changed from the last direction seen for *this caret*,
we fired a SelectionLanguageChange notification on the caret's current
Selection. This looked bogus because the caret can be switched between
selections so it would seem some selections won't get a notification when
they should, but that's how it was. Also, when the SelectionLanguageChange
notification fired we then didn't draw the caret in that iteration, which
seems even more bogus.
This patch fixes all that by moving the logic to fire SelectionLanguageChange
out to GetPaintGeometry and firing the notification every single time without
trying to detect whether the state has changed or not. I carefully examined
the implementation of SelectionLanguageChange and I'm pretty sure it's
idempotent so this should be correct. That doesn't look like an
expensive function, and runs at most once per window paint, so I'm not
worried about perf. Because we now fire SelectionLanguageChange before
reading selection or frame state, it should be fine to carry on after
calling SelectionLanguageChange and drawing the caret based on whatever
changes SelectionLanguageChange has performed.
This also lets us remove mKeyboardRTL, which as noted above seems inherently
bogus.

This is the start of the changes to caret-drawing proper.
The idea is to combine GetCaretFrame and GetCaretRect into a method
GetPaintGeometry which looks like GetGeometry but returns values
needed for painting (i.e. including bidi decorations, and returning
a null frame if we're not supposed to paint due to specific caret
state, e.g. in the "off" phase of the blink cycle).
Mostly a straightforward refactoring but there are a few interesting changes:
-- nsDisplayCaret stores its bounds instead of getting them from nsCaret on
demand. Eventually those bounds will not be stored in nsCaret at all.
-- nsDisplayCaret::GetBounds returns true for aSnap. nsCaret draws snapped
rects, so why not.
-- I removed "if (caretRect.Intersects(aDirtyRect))" in EnterPresShell.
As far as I can tell, this check is incorrect because it doesn't take
transforms into account. Since there's at most one drawn caret per window,
hence we do this at most once per paint, I don't think there's any real
performance advantage to having this check.

This patch started an attempt to remove nsFrameSelection.h from nsCaret.h
and metastasized into a rather large refactoring patch that removed it
from some other header files as well, and changed nsFrameSelection::HINT
into a global-scope enum with better names. I also converted bools
into CaretAssociationHint in a few places where that was appropriate,
but there are still some more places (GetChildFrameContainingOffset)
where bools need to be converted. I figured this patch was big enough already.

GetGeometry is used in two different ways. Sometimes it's used to get
information about a particular caret. Sometimes it's used to get
information about a particular selection that's not associated with
a caret. Splitting GetGeometry into a non-static version for the former
and a static version for the latter makes this more clear. Also it saves
code since for the latter version we don't have to get an nsCaret first.

GetCaretFrameForNodeOffset only uses the nsFrameSelection and mBidiUI
from its nsCaret. For mBidiUI we can just get the pref directly whenever
we need it. By modifying GetCaretFrameForNodeOffset to take nsFrameSelection
as a parameter, we can make it static to make it clear it isn't really
related to the state of the nsCaret.
This may also fix a bug in Selection::GetPrimaryFrameForFocusNode where
things would go unexpectedly wrong if mCaret is temporarily observing
a different selection to the Selection.
