commit 3ab5385cf6be9069d26b135647dc2df6e1f33e3f
Author: dmazzoni <dmazzoni@chromium.org>

Add support for attribute change callbacks in AXNodeData.

The idea here is that instead of Blink firing events like "name changed",
"value changed", or "checked state changed", Blink should be able to just
fire a generic notification that a node changed, and then each platform
should be able to trigger platform-specific events as needed, based on
actual changes to the attributes of an accessibilitiy node.

This change just adds support for attribute change callbacks, so it's
easy to write code that gets called whenever any particular attribute
changes.

Quite tedious, but I wanted to make sure this was both comprehensive and
exhaustively tested so we can feel confident using it.

Fire event on Mac when PRESSED state changes

On Mac, toggle buttons are subclasses of checkboxes, so we can
handle them the same as when a checkbox changes.

This is a great use of the new attribute chance callback infrastructure.

Fix DumpAccessibilityEvents tests on Mac and improve test coverage

Fix some minor issues that caused DumpAccessibilityEvents tests to fail
or behave flakily. Re-enable several tests and add many more with a
goal of covering all possible Mac notifications with tests.

This is part of a larger effort to fire fewer events from Blink
and fire them in platform-specific code instead. Increasing
test coverage will help with this.

Note that if Blink fires fewer events, we can avoid a lot of complexity where we have to walk the tree in the middle of layout or when updateDistribution needs to be called.

Ideally insetad of accessibility notifications, we just mark nodes as dirty, then update the accessibility tree as part of a lifecycle update, then events are synthesized as needed when the accessibility tree is unserialized in the browser process.

Automatically fire AX events on Mac based on tree changes

This change uses tree changes to automatically determine
which Mac AX events to fire, rather than getting the events
directly from Blink. The code to fire events from Blink is
removed for OS_MACOSX in this change.

Subsequent changes will do the same for Windows, Linux,
Android, and Chrome OS, and then we can delete all of the
code that fires specific events from Blink, and just mark
AX nodes as dirty instead.

This broke with change r477889 (https://codereview.chromium.org/2917363002)

changes from false to true, but it failed to handle cases where we
swap in a new tree root that's already loaded, which happens with
local pages and data urls.

commit b8160a95fef2f80d6b7288cc7a41a7d3761ad8b8

Refactor accessibility event messages.

Accessibility update messages and callbacks should all take:
* A tree ID (sometimes implicit)
* A single AXTreeUpdate representing a tree mutation
* Zero or more accessibility events

For historical reasons, most messages had a tree update inside each event.
This made sense before, but now we're moving towards events being mostly
implicit, so it should be more natural to send a tree update with no events.
There's no need for multiple tree updates since it's more efficient to just
merge multiple updates into the same AXTreeUpdate.

This was intended to be a pure-refactoring change with no side effects,
however one small logic change was needed to render_accessibility_impl.cc
to ensure the same node doesn't get serialized into an AXTreeUpdate twice.

It will make it easier to land future changes to make events more implicit.

commit a7b0edb2ca0c4839581cce09351544ca7553059a
Author: Dominic Mazzoni <dmazzoni@chromium.org>

Revert "Refactor accessibility event messages."

This reverts commit b8160a95fef2f80d6b7288cc7a41a7d3761ad8b8.

Reason for revert: Crashing on Windows (bug 753304)

Original change's description:
> Refactor accessibility event messages.
>
> Accessibility update messages and callbacks should all take:
> * A tree ID (sometimes implicit)
> * A single AXTreeUpdate representing a tree mutation
> * Zero or more accessibility events
>
> For historical reasons, most messages had a tree update inside each event.
> This made sense before, but now we're moving towards events being mostly
> implicit, so it should be more natural to send a tree update with no events.
> There's no need for multiple tree updates since it's more efficient to just
> merge multiple updates into the same AXTreeUpdate.
>
> This was intended to be a pure-refactoring change with no side effects,
> however one small logic change was needed to render_accessibility_impl.cc
> to ensure the same node doesn't get serialized into an AXTreeUpdate twice.
>
> It will make it easier to land future changes to make events more implicit.
>

commit 4d523f7200371430b0a57d35b4a3b0ab617ce6f4
Author: Dominic Mazzoni <dmazzoni@chromium.org>
Date: Thu Aug 31 22:29:06 2017

Add AXEventGenerator class with unit tests.

This is a new class that observes changes to an AXTree and generates events
based on that.

This will replace existing code in content/browser/accessibility that tries
to do the same thing, with a cleaner implementation that's more abstracted
and with good unit-test coverage. The next follow-up will replace the
BrowserAccessibilityManager code with this, and future changes will use it
in Views, too.

This class is also more comprehensive, it fires every event currently handled
on Win, Mac, Linux, Android, and Chrome OS.

See design doc for more context:
https://docs.google.com/document/d/1KNEkdO1iQXLrCGs2uN2dAFlRGUGCUS3cNsK7pU7oE0Y

commit 6e0fe05135f93c0396ded47ded2731467d88b96d
Author: Dominic Mazzoni <dmazzoni@chromium.org>
Date: Tue Oct 24 07:29:31 2017

Use AXEventGenerator in content/browser/accessibility

This change removes all previous code to generate events
and relies on AXEventGenerator to automatically infer all
platform-native events to fire, except for these Blink
events that can't be inferred from a tree change.

CLICKED
HOVER
LAYOUT_COMPLETE
LOCATION_CHANGED
SCROLLED_TO_ANCHOR

Once we use AXEventGenerator in ChromeVox too, we'll be
able to remove the code that fires so many events from
Blink, and just send more generic tree changes instead.

Date: Mon Dec 11 03:25:49 2017

Start to use AXEventGenerator in automation.

Adds support for AXEventGenerator in AutomationAXTreeWrapper, but to
be very conservative and safe, only uses it to fire "load complete"
events for now. Those events are really important and have both very
broad test coverage already, and are also easy to verify in manual tests.

In subsequent changes we'll switch over more and more events to come
from AXEventGenerator.

Move AXNotification to AXObjectCacheImpl

There was no need for AXNotification to be exposed in AXObjectCache.
It's more of an internal detail to accessibility and doesn't belong
in the public interface to it in core/dom.

This is a pure refactoring change only.

Migrate some more automation events to AXEventGenerator.

Only 6 new events that ChromeVox actually uses are migrated by this
change. I added comments to the other events to keep track of which
ones are candidates for migration or for removal in the future.

Switch 4 more automation events to AXEventGenerator

These four events are (1) properly covered by AXEventGenerator,
(2) don't have any very specific logic in ChromeVox, they just
call onEventIfInRange, and (3) they aren't ever fired by views
in a place where AXEventGenerator wouldn't be able to infer the
same event.

For those reasons, these 4 are safe to switch over.

Introduce MarkWebAXObjectDirty

Previously the only way for Blink to communicate a change
to the accessibility tree was via PostAccessibilityEvent.
Over time we've been migrating away from blink posting
events, and instead having it just serialize changed nodes
and let each platform infer the events it needs to fire.

Much of this refactoring has already happened, so now
we can start removing accessibility events.

This change introduces a new API, MarkWebAXObjectDirty,
which lets Blink queue up a node or a subtree to be
serialized. It uses this new API for just one event,
ActiveDescendantChanged. In follow-up changes we'll
tackle additional events, there are at least 10 ready
to migrate.

This should lead to simplification of Blink accessibility
code overall.

Note that work to remove the content/renderer/accessibility
layer is also underway, but this change shouldn't block
until that completes. Eventually, marking a node dirty
will happen within Blink and it will serialize and send
updates directly to the browser via mojo.
