Perform a sanity check in Accessible::ARIATransformRole() for the
internal REGION role: If there is no accessible name, transform
the ARIA role into the native host language role. Also perform
a sanity check when getting the AXSubrole in macOS: If the roleAtom
is nsGkAtoms::region, only return AXLandmarkRegion if the internal
role is REGION.
Create a new internal REGION role which maps to the generic landmark role
of each platform accessibility API. Update the internal mapping of region
from roles::PANE and kGenericAccType to roles::REGION and eLandmark. Also
change the AXSubrole of region from "AXDocumentRegion" to "AXLandmarkRegion",
the latter being what is specified in the Core AAM 1.1 and used in Safari.
Add eHasValueMinMaxIfFocusable to the ARIA role map so that we can
take the accessible element's interactive state into account when
determining if the value interface should be supported.
Create states::CURRENT and add it to the list of "universal" (global)
ARIA states. Map states::CURRENT to ATK_STATE_ACTIVE and emit accessible
state-change notifications when the value of aria-current is modified.
Add orientation() method to the macOS accessibility wrapper, mapping
states::Horizontal to NSAccessibilityHorizontalOrientationValue,
states::NSAccessibilityVerticalOrientationValue and the absence of
both to NSAccessibilityUnknownOrientationValue.
This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.

there is no implementation for this RelationType in place yet, but this
addition will fix off-by-one bugs when mapping newly-added relation types

In ARIA 1.1, aria-readonly became a supported property of switch,
menuitemcheckbox, menuitemradio, and radiogroup.
aria-checked is not, and has not been, a supported property of menuitem.
This property should only be supported on checkable subclasses of the
ARIA menuitem role, namely menuitemcheckbox and menuitemradio.
In ARIA 1.1, "undefined" was added as a possible value of aria-orientation,
and the default value for the combobox and treegrid roles. Therefore, remove
states::VERTICAL from the nsRoleMapEntry for these two roles and update the
associated mochitest expectations. The rest of the ARIA roles which support
aria-orientation have the correct defaults and test coverage.

DPub ARIA AXLandmarkRegion-maped roles should have an AXRoleDescription
value of "region"; not "group." This requires an explicit mapping, which
was not done during the initial implementation. No new test cases because
we currently have no means to test platform-accessibility-API mappngs via
mochitest.
According to the Core Accessibility API Mappings 1.1 spec, on macOS,
the separator role should have AXRoleDescription "splitter" and no
subrole. The incorrect AXRoleDescription is due to the subrole mapping
to AXContentSeparator. Thus removing the latter fixes the former.

In non-e10s AccessibleWrap::HandleAccEvent, we special case our handling of
CARET_MOVED and FOCUS events with a call to UpdateSystemCaretFor. In e10s mode
we were not doing the same thing for proxied events sent from content. This
threw JAWS for a loop and presumably messes up other ATs as well.
This patch modifies the IPDL messages for these two events so that we may
send the caret rect along with the event, thus allowing us to update the
system caret for proxied events as well.

Here is a scenario under which the assert is invalid:
RecvHideEvent is received on a DocAccessibleParent DAP1 that has a child document DAP2... that in turn has a child document DAP3. DAP1::RecvHideEvent calls Shutdown on its root ProxyAccessible. This recursively calls Shutdown on child ProxyAccessibles until it reaches the one that is the parent of the child document DAP2. ProxyAccessibleBase::Shutdown then attempts to Unbind DAP2, which calls DAP1::RemoveChildDoc, which trips the assert because DAP2 has child document DAP3.
In content processes, we want to avoid a situation where a DocAccessible has lost its IPC actor (DocAccessibleChild) but finds itself processing a delayed request to take on child documents. In this case, we shut down the child documents as they are no longer valid.
Now that we inherit the recommended configurations, many definitions are handled semi-automatically.

It is awkward to need to have a DocAccessibleChild to send events with before
DocAccessible::DoInitialUpdate() is called because we might not have a
TabParent for the document until then. However we could try to fire reload
events on documents before DoInitialUpdate() was called which would require
having a DocAccessibleChild there to send the load event to the parent process.
However before DocAccessible::DoInitialUpdate() is called the document already
has a pending load event. If a document hasn't yet been the subject of a load
event it doesn't make a lot of sense to fire a reload event for that document,
and then the initial load event. So it should be safe to skip firing
reload events for documents where mLoadEvent specifies a load event to
fire in the future.
We sometimes briefly have more than one root DocAccessible associated with a TabChild, for example, while navigating links in a page. This patch makes sure that we use the correct accessible when delaying messages that we forward to the parent process.
This avoids conflicts with mozilla::dom::FrameType.

The a11y COM handler consists of two classes. AccessibleHandler is the one that
is actually interposed by COM between the client and the proxy. It implements
IAccessible2_3, IServiceProvider, and IProvideClassInfo. It is derived from
mscom::Handler which takes care of most of the COM boilerplate for handler
instantiation. AccessibleHandler must override a few virtual functions from
mscom::Handler:
* QueryHandlerInterface - mscom::Handler must implement the "real" QI. This is
the method that mscom::Handler uses to delegate to the implementer.
* ReadHandlerPayload - deserializing the payload. This uses
mscom::StructFromStream and the IA2Data_Decode function that was generated by
midl. It should essentially be the inverse of the serialization code in the
IHandlerProvider implementation inside Gecko.
* MarshalAs - identical to IHandlerProvider::MarshalAs
* GetHandlerPayloadSize and WriteHandlerPayload - it sucks that we have to
include these, but they are neccessary for the scenario when COM wants to
make a proxy of a proxy. When that happens, we need to get COM to serialize
the payload again; it isn't smart enough to recognize payloads in existing
proxies and copy them itself.
In order to reduce round trips, AccessibleHandler implements the most
sophisticated IA2 interface. This way the client has access to any of those
interfaces from IDispatch all the way down to IAccessible2_3 without needing to
incur additional round-trips to obtain them.
We also implement IServiceProvider so that a client may QueryService for an IA2
interface without needing to incur more round trips. In addition, we maintain
a list of service IDs that we definitely do not support, and handle those
locally instead of incurring an IPC round-trip.
We also implement IProvideClassInfo because NVDA's python code (and presumably
other ATs that use interpreted languages) supports using that interface to
assist its FFI library with resolution of our COM objects.
COM wraps each instance of an IAccessible* proxy with an AccessibleHandler
object. Proxies whose interfaces are not part of the IDispatch ... IAccessible2_3
hierarchy are not wrapped with handlers (though this might change in the future
if we need to expand coverage). AccessibleHandler implements IAccessible2_3 such
that, if we have cached data available for a particular IA2 method, we provide
that cached data to the client. Otherwise we pass on the request to the COM
proxy for retrieval via IPC.
The other class in the handler dll is AccessibleHandlerControl. This class
implements the IHandlerControl interface that is provided to IGeckoBackChannel.
Gecko dispatches cache invalidation events using this interface. This class
is a singleton within the handler dll and manages shared, handler-wide resources.

A general outline of the COM handler (a.k.a. the "smart proxy"):
COM handlers are pieces of code that are loaded by the COM runtime along with
a proxy and are layered above that proxy. This enables the COM handler to
interpose itself between the caller and the proxy, thus providing the
opportunity for the handler to manipulate an interface's method calls before
those calls reach the proxy.
Handlers are regular COM components that live in DLLs and are declared in the
Windows registry. In order to allow for the specifying of a handler (and an
optional payload to be sent with the proxy), the mscom library allows its
clients to specify an implementation of the IHandlerProvider interface.
IHandlerProvider consists of 5 functions:
* GetHandler returns the CLSID of the component that should be loaded into
the COM client's process. If GetHandler returns a failure code, then no
handler is loaded.
* GetHandlerPayloadSize and WriteHandlerPayload are for obtaining the payload
data. These calls are made on a background thread but need to do their work
on the main thread. We declare the payload struct in IDL. MIDL generates two
functions, IA2Payload_Encode and IA2Payload_Decode, which are used by
mscom::StructToStream to read and write that struct to and from buffers.
* The a11y payload struct also includes an interface, IGeckoBackChannel, that
allows the handler to communicate directly with Gecko. IGeckoBackChannel
currently provides two methods: one to allow the handler to request fresh
cache information, and the other to provide Gecko with its IHandlerControl
interface.
* MarshalAs accepts an IID that specifies the interface that is about to be
proxied. We may want to send a more sophisticated proxy than the one that
is requested. The desired IID is returned by this function. In the case of
a11y interfaces, we should always return IAccessible2_3 if we are asked for
one of its parent interfaces. This allows us to eliminate round trips to
resolve more sophisticated interfaces later on.
* NewInstance, which is needed to ensure that all descendent proxies are also
imbued with the same handler code.
The main focus of this patch is as follows:
1. Provide an implementation of the IHandlerProvider interface;
2. Populate the handler payload (ie, the cache) with data;
3. Modify CreateHolderFromAccessible to specify the HandlerPayload object;
4. Receive the IHandlerControl interface from the handler DLL and move it
into the chrome process.
Some more information about IHandlerControl:
There is one IHandlerControl per handler DLL instance. It is the interface that
we call in Gecko when we need to dispatch an event to the handler. In order to
ensure that events are dispatched in the correct order, we need to dispatch
those events from the chrome main thread so that they occur in sequential order
with calls to NotifyWinEvent.

unfortunately because creating a DocAccessibleParent is not atomic one can be
created by AllocPDocAccessible(), but then RecvPDocAccessibleConstructor() can
fail. If that happens we will call actor destroyed on the new
DocAccessibleParent, however because the constructor messaged failed it will
not have a wrapper. That means this assert does not necessarily hold.
The Manager is set by IPDL for remotely constructed objects but our DocAccessibleChilds are created on the child process side, so we need to assign a manager in the constructor so that we can find it when needed.

Its possible to coalesce away events such that the first two events in the
queue are reorder events where the second reorder can be coalesced with the
first. In that case there's no point in shuffling the list before removing
the second reorder event.
Really, there are only two cases we need to worry about. Either
IsSelectionCached(), and then our SelectionProperties has the data we want, or
not and then we have a non-null mSelCon which has the data we want.
Since we are now using cached selection state a lot more (instead of
initializing the editor whenever someone asks for selection state), we need to
actually update it more correctly when .value is set.
And since we now update the cached selection state for the case when .value has
been set (to point to the end of the text), we need to change
HTMLInputElement::HasCachedSelection to return false for that case. Otherwise
we will always do eager editor init on value set. We handle that by not doing
eager init if the cached selection is collapsed.
The web platform test changes test the "update on .value set" behavior. They
fail without this patch, pass with it.

a BindChildDoc message can race with the parent process shutting down a tab.
The result of that is that RecvBindChildDoc() can be called on a
DocAccessibleParent that has already been shut down by the destruction of the
owning TabParent.
sending the emulated window information is basically unrelated to sending the
parent COM proxy to the child process, and in the future it will be useful to

Use strcmp() instead of strncmp() when comparing the AtkObject name
before changing it. 9133117f410c06ad7fa25323a168bc97200043b9 changed
from Equals() to strncmp() to prevent issues related to embedded NUL
bytes, but the change lead to only checking if the AtkObject name has
the new value as prefix. Instead, use strcmp() to check the whole
C strings, but still stopping at the first NUL byte in the new name.
strcmp() has to be safe here, as NS_ConvertUTF16toUTF8::get() has to
return a NUL-terminated string or the code would crash a few lines
below when calling strdup() on it.
the outer doc of a top level content document does not necessarily exist when
we recieve the PDocAccessibleConstructor message for it. So we shouldn't asser
there is an outer doc here.
Follow-up to fix breakage in accessibility caused by the bundle
conversion. In particular, optString(foo) should have been converted to
getString(foo, "") because optString returns "" by default.
Also fix a small bug in Presentation.jsm where an array or null should
be used instead of a string.
There are cases where there is no good reason to shutdown the child document
actors before the parent. For example when TabParent::DestroyInternal() is
about to send the Destroy message we might as well just shut down the top level
document and let that tear down the rest.
