EditorBase stores a text node, offset in it and length in it of composition
string directly. However, this wastes memory space if user never uses IME
or user only sometimes uses IME. Additionally, storing all data in
TextComposition is better than current design when other classes like
CompositionTransaction wants some information of both EditorBase and
TextComposition.
This patch moves those 3 members from EditorBase to TextComposition.

According to the log in crash reports, eCompositionCommitRequestHandled is
sent to ContentCacheInParent twice or more for a composition. This causes
breaking mPendingCompositionCount and mPendingEventsNeedingAck management.
Currently, nsIWidget::NotifyIME() should be called only by
TextComposition::RequestToCommit(). Therefore, the method should manage if
it should request it actually. If the composition has already received
eCompositionCommit(AsIs) event, it shouldn't request it because parent process
may have already stated new composition and it shouldn't be broken by request
for old composition.

Currently, widget doesn't show VKB when input context change is caused by JS.
However, if it's caused by an event handler of a user input, user may expect
to open VKB. For example, if a touch event in fake editor causes moving
focus to actual editable node, user expect to show VKB.
Therefore, InputContextAction should declare two causes. One is unknown but
occurred during handling non-keyboard event. The other is unknown but occurred
during handling keyboard event.
However, EventStateManager doesn't have an API to check if it's being handling
a keyboard event. Therefore, this patch adds it first.
AutoHandlingUserInputStatePusher sends event type to StartHandlingUserInput()
and StopHandlingUserInput() of EventStateManager and sUserKeyboardEventDepth
manages the number of nested keyboard event handling. Therefore,
EventStateManager::IsHandlingKeyboardInput() can return if it's handling a
keyboard event.
IMEStateManager uses this new API to adjust the cause of changes of input
context.
Finally, InputContextAction::IsUserInput() is renamed to IsHandlingUserInput()
for consistency with EventStateManager and starts to return true when the
input context change is caused by script while it's handling a user input.

This patch declares a new default action, "horizontal scroll", this scrolls
content horizontally with deltaY of wheel events and ignores deltaX and deltaZ.
This is used for default action with Shift key in default setting except on
macOS. On macOS, legacy mouse's vertical wheel operation with Shift key causes
native horizontal wheel event. Therefore, we don't need to use this new
default action on macOS. Additionally, old default action with Shift key,
navigating history, is moved to with Alt key. This makes same settings between
macOS and the others. So, this is better for users who use macOS and another
OS and web app developers who check wheel events only on macOS or other
platform(s).
For simpler implementation, default action handlers moves deltaY values to
deltaX values temporarily *only* while they handle wheel events. This is
performed by AutoWheelDeltaAdjuster and restored after handling it
automatically.
So, in other words, even if default action is "horizontal scroll", web apps
receives wheel events whose deltaY is not zero but its content will be
scrolled horizontally. This is same as Chromium, so, this behavior shouldn't
cause any incompatible behavior with it.

Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.

Smart Location Bar (a.k.a URL bar) has some features, loading inputted URL
directly, searching bookmark items and history items, and search inputted words
with registered search engine.
So, it does not make sense its inputmode is "url". E.g., neither showing URL
specific software keyboard nor switching IME open state automatically for
typing URL may not be expected in most cases.
Unfortunately, there is no proper inputmode value for Smart Location Bar.
Therefore, this patch uses "mozAwesomebar" value and accepts the value only in
chrome documents. This value should be handled by each native IME handler
properly.

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

nsIEventListenerChange::changedListenerNames is an nsIArray attribute that
contains nsIAtoms. Bug 1396693 made it `noscript` to help with nsIAtom
deCOMtamination (bug 1392883) but more changes are needed: that array
eventually needs to be changed to nsTArray<RefPtr<nsIAtom>>.
Turns out the attribute has a single use, in a11y code. That code merely
iterates over the list and counts how many atoms it contains that match
"onclick", "onmousedown", and "onmouseup".
So this patch moves that counting functionality inside nsEventListenerChange by
changing the attribute to `countOfEventListenerChangesAffectingAccessibility`.
This saves us from having to expose the array of atoms via XPIDL.

This isn't a super essential feature, and is just a change to try to bring us in
line with chromium and the spec. As this has apparent web compat issues, and
DataTransfer is a hard to test area, this patch moves the changes behind a pref,
which we can come back to turning on after we ship 57.
Currently, IMEStateManager::OnChangeFocusInternal() tries to sync the state
whether menu keyboard listener is installed between itself and active remote
process -- When menu keyboard listener is installed, it posts a message to
_only_ active remote process. When menu keyboard listener is uninstalled,
it posts a message to _only_ active remote process. So, it's not guaranteed
that active remote process at installing and uninstalling may be different.
If it's different, IMEStateManager in the old remote process believes that
menu keyboard listener is still installed. This is what the cause of IME
unavailable in a remote process.
Current approach must be wrong. IMEStateManager should manage menu keyboard
listener state only in the process which the listener is installed in. Then,
when menu keyboard listener is uninstalled, IMEStateManager needs to restore
the latest input context in the remote process without asking the remote
process.
Therefore, this patch does:
* stops IMEStateManager::OnChangeFocusInternal() posting message when menu
keyboard listener is installed and uninstalled.
* removes the message sender and receiver from PBrowser.
* cache the latest input context of active remote process in
IMEStateManager::SetInputContextForChildProcess().
* make IMEStateManager::SetInputContextForChildProcess() not set input context
when menu keyboard listener is installed in the process.
* tries to restore latest input context in the remote process in
IMEStateManager::OnChangeFocusInternal(). If there is no cached input
context, it does nothing and waits next SetInputContextForChildProcess() call.
* clears the cache when IMEStateManager::OnChangeFocusInternal() changes
active remote process to different one or nullptr.
So, this must improve performance at activating and inactivating memubar and
opening and closing popup menu in the main process.

With previous change, KeyboardEvent is dispatched even when invisible window
has focus. However, nsRootWindow::GetControllerForCommand() returns controller
for focused window even when the window is invisible because it uses
nsFocusManager::GetFocusedDescendant() to retrieve focused window.
Perhaps, we can assume that users won't expect to do something with invisible
window when they type some keys. Then, nsRootWindow::GetControllerForCommand()
should return controller for visible ancestor window if focused window is
invisible.
This patch makes nsFocusManager::GetFocusedDescendant() can return only visible
descendants. However, it already has a bool argument. Therefore, it should
have a flag instead of adding new flag. Most changes of this patch is replacing
its callers.
Then, nsRootWindow::GetControllerForCommand() and nsRootWindow::GetControllers()
should have a bool flag if it should return controller(s) for visible window.
This patch adds a bool flag for it. Fortunately, the interface isn't scriptable.
Finally, this patch makes nsXBLPrototypeHandler::DispatchXBLCommand() and

When setting value of <input type="text">, nsTextEditorState removes all
ranges of normal selection first. Then, TextEditor sets the value. Finally,
TextEditor collapses the selection at the end of the text.
In bug 1386471, we got that there are some problems to remove the call of
Selection::RemoveAllRanges() in nsTextEditorState. Therefore, we need another
approach to improve Selection::Collapse().
The approach of this patch is, when removing all ranges from normal selection,
Selection can cache an nsRange instance if there is an instance which is not
referenced from other than the Selection (i.e., it'll be removed when
Selection::Clear() is called). Then, Selection::Collapse() can reuse it. With
this fix, Selection::Collapse() can reduce allocation cost and may reduce some
other cost like adding it to mutation observer.
However, keeping nsRange instance may cause increasing mutation observer's cost
since nsRange will be adjusted its start node/offset and end node/offset with
mutation observer to guarantee that the range is always valid. So, we can
cache such range only when the caller (or its callee) will set selection range
later. Therefore, this patch adds Selection::RemoveAllRangesTemporarily()
and make only nsTextEditorState::SetValue() and
ContentEventHandler::OnSelectionEvent() use it.
