DeleteTextTransaction should have 3 factory methods. One is, simply to create
an instance with a pair of offset and length. The others are, to create an
instance for deleting a previous or next character at offset.
The former was EditorBase::CreateTxnForDeleteText() and the latter was
EditorBase::CreateTxnForDeleteCharacter(), but this patch creates
DeleteTextTransaction::MaybeCreate() for the former,
DeleteTextTransaction::MaybeCreateForPreviousCharacter() and

While moving children of a container to another container, mutation observer
may move children before moving and/or move node immediately after the
insertion point. Therefore, EditorBase should store all children which
should be moved with a local variable. Then, move one by one carefully.
E.g., if a child before being moved is moved to different container, it
shouldn't be moved because JS already handles it as expected for the web
app. If next sibling of the insertion point has been moved, EditorBase
should stop moving the remaining children because it may move children to
odd position and it may cause dataloss.
This patch creates EditorBase::MoveChildren() and it moves children carefully
with above checks. Additionally, making its callers simpler, this patch also
creates EditorBase::MovePreviousSiblings() and MoveAllChildren().

E.g., some users of the template class may initialize it with a container and
offset in it but it may not refer mRef or may refer after modifying offset.

It assumes that mRef is always initialized when it's called but can be
invalidate mOffset until retrieved actually. This is necessary for
nsRange::mStart and nsRange::mEnd since the offset may be changed when
some nodes are inserted before the referring node.
So, now, InvalidateOffset() should be a protected method and make nsRange a

performance of nsINode::IndexOf(). However, there are a lot of regression

Currently, HTMLEditRules::WillInsertBreak() checks if the editing host can
contain a <p> element as a child or a descendant. However, this is not enough.
If an inline element has a block element which can contain a <p> element,
current implementation considers to insert a <br>. This is possible when
* The editing host is an unknown element including user defined element.
* The editing host is an inline element and its children and/or descendants
were added by JS. E.g., <span contenteditable> element can have <div>
element.
I think that we should consider to insert a <br> element when:
- There is no block ancestors in the editing host.
- The editing host is the only block element and it cannot contain <p> element
or the default paragraph separator is <br> element.
- The nearest block ancestor isn't a single-line container declared in the
execCommand spec and there are no block elements which can contain <p>
element.
Note that Chromium checks if CSS box of ancestors is block too. However,
it must be out of scope of this bug.

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
EventStateManager::DoContentCommandEvent() retrieve controller for visible
window since they are always handles user input.

EditorBase::EndPlaceholderTransaction() has hidden caret. However, it doesn't
do it anymore. However, bug 805697 didn't remove unnecessary code that
retrieves and hold nsIPresShell and nsCaret. This patch removes them.

I would like to remove more dependency of old nsISelection interface from editor if possible. So we can replace nsISelection::GetRangeCount with Selection::RangeCount.

nsISelectionController::SELECTION_* are declared as bit-mask. However, no
methods of nsISelectionController treat them as bit-mask and these
values need a switch statement in nsFrameSelection to convert SelectionType to
array index of nsFrameSelection::mDOMSelections because it's too big to create
an array to do it. Additionally, this conversion appears profile of
attachment 8848015.
So, now, we should declare these values as sequential integer values.
However, only nsTextFrame uses these values as bit-mask. Therefore, this patch
adds new type, SelectionTypeMask and creates new inline method,
ToSelectionTypeMask(SelectionType), to retrieve mask value for a SelectionType.

nsTextFrame stores text as single byte character array if all characters are
less than U+0100. Although, this saves footprint, but retrieving and modifying
text needs converting cost. Therefore, if it's created for a text node in
<input> or <textarea>, it should store text as char16_t array.

EditorBase::GetSelection() sometimes appears in profile. So, it shouldn't be
called in nsIEditor::EndOfDocument() if the callers of
nsIEditor::EndOfDocument() has a pointer to Selection.
This patch adds EditorBase::CollapseSelectionToEnd() for the internal method
and make all callers of nsIEditor::EndOfDocument() use it.

nsINode::IndexOf() is expensive especially when it's in a hot path, it's too
expensive. So, EditorBase::GetChildOffset() and EditorBase::GetNodeLocation()
should check child's siblings first. If some of them are nullptr, it means
that it's first child or last child of the parent.
Note that EditorBase::GetChildOffset() may return wrong index if it's called
while aChild is being removed from aParent or aParent isn't actual parent of
aChild. However, there are MOZ_ASSERTs to ensure value isn't -1. Therefore,
it's safe to assume that aParent is always the parent of aChild and it won't
be called from ContentRemoved() of mutation observers.

AutoPlaceHolderBatch can take EditorBase class and its inherited class, AutoEditBatch, can be removed if we implement other constructor which doesn't take transaction name.
Additionally, nsIEditor::(Begin|End)PlaceHolderTransaction() are referred only by AutoPlaceHolderBatch. Therefore, they can be non-public methods and removed from nsIEditor interface.
Note that this patch also repalces "PlaceHolder" with "Placeholder" since it's a word.

nsComposerCommands uses some simple getter methods. They can be simpler non-virtual methods. So, we should do it.
Note that this changes that EditorBase::GetIsSelectionEditable() won't return error. However, it has returned error only when selection controller isn't available. That means that the selection controller has been destroyed and the editor will be destroyed. So, this must not be problem since it returns false (non-editable) instead and won't break any behavior since the editor won't be editable by users nor JS anymore.

CompositionTransaction forgets to call EndBatchChanges when GetSelectionController returns error, so we should use RAII class instead.

This method can be extremely hot, so we need to remove all sources of XPCOM
overhead from it. This includes the usages of weak pointers (thanks to the
previous parts), refcounting, and QueryInterface.
I kept the callers hold the selection controller alive by assigning the
return value to an nsCOMPtr in places where the methods called on it could
have a remote chance of messing with the lifetime of objects.
Besides some unnecessary copying and malloc overhead that this removes, it
also removes a call to dom::Text::GetData() which we used to only make to
get the old length of the text node before modifying it. Turns out that
this old length was already obtained once in SetTextImpl().
