Now, we have an security issue. mCommittedCharsAndModifiers may be initialized with multiple WM_(SYS)CHAR messages. However, if it's generated by odd (or malicious) middleware, mCommittedCharsAndModifiers may be overflown because it has only fixed array. For fixing this issue, first, we should hide the members for making the users not depend on the design of UniCharsAndModifiers.
This patch changes UniCharsAndModifiers to a class and hiding mChars and adding |CharAt() const|.

This patch creates NativeKey::DispatchKeyPressEventsWithRetrievedCharMessages() for dispatching eKeyPress event with mCommittedCharsAndModifiers when it stores following printable WM_(SYS)CHAR messages.
Using loop for dispatching eKeyPress event for every WM_(SYS)CHAR message is wrong because WidgetKeyboardEvent::mKeyValue is initialized with mCommittedCharsAndModifiers and it causes TextEventDispatcher dispatching multiple eKeyPress events at every call of MaybeDispatchKeypressEvents(). Therefore, if mKeyValue is "^^", eKeyPress event is dispatched 4 times --for the first message, eKeyPress events are fired for each "^" and for the second message, eKeyPress events are fired again for each "^"--. Therefore, when it handles WM_(SYS)KEYDOWN and it causes inputting one or more printable characters, it's the easiest way not to use HandleCharMessage().
The new method calls TextEventDispatcher::MaybeDispatchKeypressEvents() only once and it requests to call the callback method with new argument of MaybeDispatchKeypressEvents() when it needs to dispatch 2 or more eKeyPress events. Then, NativeKey::WillDispatchKeyboardEvent() can set each eKeyPress event to raw information of the message and proper modifier state.
With this change, we can dispatch multiple eKeyPress events with retrieved WM_(SYS)CHAR message information rather than retrieved information from active keyboard layout. Therefore, NeedsToHandleWithoutFollowingCharMessages() doesn't return true even when mCommittedCharsAndModifiers stores two or more characters.
FYI: there is a bug in test_keycodes.xul. That is, Alt+'A' of Greek keyboard layout should cause WM_SYSCHAR with a corresponding Greek character but ASCII characters are specified. Therefore, this patch includes the fix of these bugs

First, mCommittedCharsAndModifiers should be initialized with following char messages because the messages could be different from the information of current keyboard layout.
So, this patch guarantees that mCommittedCharsAndModifiers are same as the user expected when there is one or more WM_CHAR or WM_SYSCHAR messages.

Now, NativeKey::HandleCharMessage() has almost same code, one is for dispatching eKeyPress event for non-printable keys or printable keys when one of Alt or Ctrl key is pressed, the other is for printable keys when Alt or Ctrl key is pressed.
The difference of them is, the former block removes Alt state and Ctrl state for handling AltGr key. When AltGr key is pressed, both Alt and Ctrl state are true. However, EditorBase treas keypress events whose altKey or ctrlKey is true as non-printable key event. Therefore, we need to set these modifier state to false when AltGr key is pressed and the key causes some text.
Note that as far as we know, when a key press with AltGr doesn't cause any characters, WM_CHAR isn't generated. Therefore, we don't need to check with complicated logic if the key event is actually inputting a character.

This patch makes NativeKey::HandleCharMessage() stop dispatching eKeyPress event when the message is inputting a control character. NativeKey::HandleCharMessage() runs following cases:
1. WM_KEYDOWN followed by a WM_CHAR message whose wParam is not a control character causes inputting printable characters.
2. WM_CHAR message is received without WM_KEYDOWN message.
So, when HandleCharMessage() is called for a control character, it's unusual case. E.g., another application sends only WM_CHAR message with a control character.
On the other hand, Gecko is the only browser which dispatches "keypress" event even if pressed printable key doesn't cause inputting any characters. And such "keypress" event is used for shortcut key handling and some default action handling. So, even if we stop dispatching eKeyPress event from HandleCharMessage(), it shouldn't affect most users.
Note that this patch does NOT change the behavior when the user inputs a control character with usual keyboard layout such as Ctrl+A of en-US keyboard layout because DispatchKeyPressEventsWithoutCharMessage() dispatches eKeyPress event in such cases.
This patch also adds a lot of tests with Ctrl or Alt state for detecting regressions.

When key combination is reserved by the system, web apps shouldn't be able to consume the key events. In such case, we've decided that we never expose the key events in web contents (including chrome contents). Therefore, NativeKey stops dispatching keyboard events only for Alt+Space.
However, new code of the fix of bug 1300003 always consumes WM_SYSCHAR which follows WM_SYSKEYDOWN of Alt+Space. This is the cause of bug 1305943.
For fixing this bug, NativeKey should have a helper method, IsReservedBySystem(), and when it returns true, it should do nothing when Handle*Message() is called and should not consume following WM_SYSCHAR messages at handling WM_*KEYDOWN.
Unfortunately, it's impossible to test this regression because nsDOMWindowUtils::SendNativeKeyEvent() may call nsIWidget::SynthesizeNativeKeyEvent() asynchronously. See <https://dxr.mozilla.org/mozilla-central/source/dom/base/nsDOMWindowUtils.cpp#1105-1108>. Therefore, it cannot return if it's consumed.

Currently, NativeKey::DispatchPluginEventsAndDiscardsCharMessages() calls nsWindowBase::DispatchPluginEvent() and nsWindowBase::DispatchPluginEvent() does nothing when windowless plugin doesn't have focus. However, this is unclear when other developers read the code of DispatchPluginEventsAndDiscardsCharMessages() and it causes unnecessary virtual calls. So, it should try to dispatch plugin events only when a windowless plugin has focus.
For making the check safer, nsWindowBase should expose the method to check it as ShouldDispatchPluginEvent().

NativeKey removes odd WM_CHAR messages which are caused by ATOK or WXG if the user tries to do "Kakutei-Undo" (meaning "undo the last commit") after dispatching eKeyDown event.
However, NativeKey should remove them from the queue first because there are some problems:
* If focus is moved during dispatching an eKeyDown event, we'll fail to remove the messages from the queue.
* If dispatching eKeyDown advance native event loop due to entering to a modal loop or dosing synchronous XHR, the message pattern is broken before removing the odd messages from the queue.
After removing the odd char messages, NativeKey should store them with mRemovedOddCharMsgs because NativeKey needs to dispatch them to focused windowless plugin.
Note that this patch also fixes a bug of the loop to remove the odd WM_CHAR messages. Old code removes only one WM_CHAR messages, but we need to remove all WM_CHAR messages before WM_KEYUP. This must be a regression.

On Windows, some keys are called "extended key". Their scan code include 0xE000. For example, Enter key in standard position is 0x001C but Numpad's Enter key is 0xE01C. Unfortunately, both of them cause same virtual keycode value, VK_RETURN. Therefore, currently, nsIDOMWindowUtils.sendNativeKey() can synthesize only one native key event of them (only non-extended key's event). Additionally, MapVirtualKeyEx() API with MAPVK_VK_TO_VSC (even with MAPVK_VK_TO_VSC_EX) don't return extended scancode value as expected.
For solving these issues, we should include scan code value to the virtual keycode value at calling sendNativeKey().
Fortunately, virtual keycode value on Windows is 0 ~ 255 (0x00 ~ 0xFF) but aNativeKeyCode of sendNativeKey() is int32_t. So, we can use upper 16 bit for specifying scan code.
This patch explicitly specifies scan code value at defining WIN_VK_* in NativeKeyCodes.js. Additionally, this patch duplicates native virtual keycode definition for Home, End, Insert, Delete, PageUp, PageDown, ArrowUp, ArrowLeft, ArrowDown, ArrowRight and Enter as WIN_VK_* and WIN_VK_NUMPAD_*.

On some keyboard layouts, a key sequence, a dead key -> another dead key, may produce a composite character instead of two base characters for each key. For example, with "Russian - Mnemonic" keyboard layout on Win 8 or later, both 's' and 'c' are dead keys but key sequence, 's' -> 'c', produces a Unicode character.
For solving this issue, this patch fixes 2 bugs:
First, KeyboardLayout::GetDeadKeyCombinations() doesn't add dead key entry if 2nd key is a dead key (::ToUnicodeEx() returns -1). In such case, it should add a dead key entry with the first character which is produced when only the 2nd key is pressed (the character is called as "base character" and used for index of the dead key table).
Next, KeyboardLayout::InitNativeKey() should check if 2nd dead key press produces a composite character. If it's produced, it should initialize given NativeKey with the composite character. Otherwise, it should initialize with base characters of each key. This patch does it with KeyboardLayout::MaybeInitNativeKeyWithCompositeChar().
Finally, we should add automated test for this. However, unfortunately, it's not available on Win7 and our infra is still using Win7 for running automated tests. Therefore, this patch doesn't include new automated tests.

There are 2 bugs and this patch fixes them once.
First, NativeKey::WillDispatchKeyboardEvent() is used to setting alternative charCode values for every eKeyPress event. However, for supporting "reserved" shortcut keys, now, it sets alternative charCode values to eKeyDown too. However, they are really different. eKeyPress events are fired for every character to be inputted by a key press sequence. On the other hand, eKeyDown event is fired only once for a key sequence. Therefore, now, NativeKey::WillDispatchKeyboardEvent() needs to set alternative charCode values for all characters inputted by the key sequence to eKeyDown event.
The other is not a new bug. NativeKey::WillDispatchKeyboardEvent() sets the last eKeyPress event's special alternative charCode values, such as unshifted Latin character, shifted Latin character and some character which can be computed from virtual keycode. This is performed when given index is the last index of the longest input string of the key. However, the value includes different shift key state. I.e., when different shift key causes longer text input, NativeKey::WillDispatchKeyboardEvent() won't set the special alternative charCode values to any eKeyPress events. For example, when Ctrl+T is pressed with Arabic keyboard layout, its unshifted input string length is 1 but shifted input string length is 2. Then, eKeyPress event is fired only once, but NativeKey::WillDispatchKeyboardEvent() waits second eKeyPress event.
Therefore, this patch makes the method append alternative charCodes for all remaining characters and detect the last event correctly with mCommittedCharsAndModifiers (it's used for KeyboardEvent.key value of eKeyDown event and the count of eKeyPress events is same as the value's length).

This patch prevents the Windows widget code from dispatching the contextmenu
event if APZ is handling touch input. Instead, the APZ code processes the
raw touch input, and will fire a contextmenu event when the user lifts their
finger after a long-press action, in keeping with the Windows platform
convention. Doing it this way also allows us to respect web conventions where
the web content can prevent the contextmenu event from firing by calling
preventDefault on the touchstart event; this was not possible when dispatching
the contextmenu event directly from the widget code.
This also makes long-pressing on browser chrome components work properly, as
it just shifts the point in time that the contextmenu event is fired without
changing any of the code that triggers the XUL popup. However, some changes
were needed to have the widget code ignore the synthetic mouse events that
the Windows platform sends us, because those would otherwise immediately
dismiss the contextmenu popup after it appeared.

Returing TS_E_NOLAYOUT while ATOK shows suggest window causes moving suggest window to odd position. This causes flicking the window. Therefore, we shouldn't return TS_E_NOLAYOUT in this case. In this case, ATOK queries whole rect of composition string. So, we can return TS_E_NOLAYOUT for other cases.

They don't need to be NS_IMETHOD, but they should be MOZ_MUST_USE. Adding the
latter catches a few missing checks, which the patch adds.
The patch also gives PuppetWidget an InfallibleCreate() function, which makes
the infallibility of PuppetWidget creation clear.
This patch makes GetBounds(), GetScreenBounds() and GetClientBounds() more
obviously infallible, like existing functions such as GetNaturalBounds() and
GetClientSize(). This results in clearer behaviour in nsCocoaWindow.mm if
Objective C exceptions occur. Along the way, the patch removes some useless
failure checks for these functions.
The patch also removes the NS_IMETHOD from GetRestoredBounds and makes that

ATOK 2011 - 2016 check focused window class name if it's a Mozilla's window. Then, they refer native caret position for deciding its popup window. However, future ATOK release will stop referring native caret position on Mozilla's windows. Therefore, we can stop creating native caret for new ATOK.

ContentEventHandler and ContentCache allow 0 length text rect query. However, if selection is collapsed and caret is at the queried offset, they return actual caret rect whose height (in horizontal layout, width in vertical layout) may be different from actual font height of the line.
Therefore, it may cause "dancing" of candidate or suggest window of TIP. Therefore, we should query text rect at least 1 length. Then, even if there is no character at the offset, they computes caret rect with previous character.

When TSFTextStore::GetTextExt() needs to hack the queried range, it means that the method should not return TS_E_NOLAYOUT since the hacks are implemented for that. However, currently, if hacked offset is still at modified offset, it returns TS_E_NOLAYOUT. This causes flicking IME windows.
For avoiding that, this patch adjust the hacked offset to the last unmodified offset or offset of the start of composition string. Even if there is no modified character in the composition string, we can use the offset since even if there is no character at the offset, query content event returns caret rect at the offset and if there are old characters, it returns its rect which the user still see. So, the rect at the composition start is useful until layout is modified actually.

Currently, TSFTextStore::GetTextExt() checks the offset with mContentForTSF.MinOffsetOfLayoutChanged() as "the first offset of modified characters", however, TSFTextStore::Content::IsLayoutChangedAfter() needs actual offset - 1. This is really not useful. So, we should rename it to IsLayoutChangedAt() and check the offset simply.
Additonally, TSFTextStore::GetTextExt() should set previous offset of MinOffsetOfLayoutChanged() when it hacks the queried range for avoiding bug of active TIP since setting offsets to the result of MinOffsetOfLayoutChanged() means the offset's layout is always not computed yet.

In CreateAndSetFocus(), SetInputScope() is called *after* setting focus to the context. At this time, Google Japanese Input retrieves InputScopes. Therefore, TSFTextStore returns IS_DEFAULT. But after that, Google Japanese Input tries to retrieve InputScopes after every notification (in this case, a call of ITextStoreACPSink::OnLayoutChange()). Then, we return IS_URL due to set after returns IS_DEFAULT.
This is actually our fault, but according to the other TIPs, Google Japanese Input shouldn't commit composition at detecting an InputScope change, though.

This patch stops the widget code from passing along touch-derived contextmenu
events straight from Windows to Gecko, and instead lets the APZ gesture
detection code handle it. This allows the contextmenu event to be prevented
according to web standards, e.g. if the touchstart event is cancelled.
This changes to browser.js will affect both Linux and Windows, but the behaviour
implemented is in line with native Windows touch behaviour. We may want to
add an alternate codepath for Linux to better simulate "native" Linux behavior,
if there is such a thing for touch-derived contextmenu.

I'm still not sure what we should do in this case, though.
If mContentForTSF is initialized and there are some unknown changes in actual contents, i.e., not caused by composition of the active TIP itself, we cannot set selection range properly in some cases.
For example, if TSF tires to set non-empty selection range but the range has been removed by web apps.
For now, let's try to return E_FAIL in such case because that should occur at reconversion or something immediately after previous content change not caused by previous composition. If TIP does nothing in this case, user can retry with same operation after all pending text changes are notified to TSF.

TSFTextStore shouldn't notify TSF of selection change until MaybeFlushPendingNotifications() is called and there is no cached content because while there is cached content, neither TSF nor TIP may allow to change selection by web applications. Therefore, ITextStoreACP::GetSelection() and similar methods need to use mSelection instead of actual selection in the focused editor. Therefore, TSFTextStore should store selection change data during keeping storing content cache and notify it when the cache is cleared. So, when TSFTextStore notifies TSF of selection change, TSFTextStore needs to update mSelection to the actual selection which is stored in mPendingSelectionChangeData.

I think that we can drop nsIMEUpdatePreference::DontNotifyChangesCausedByComposition(), i.e., nsIMEUpdatePreference::NOTIFY_CHANGES_CAUSED_BY_COMPOSITION because it's now used only by TSFTextStore but TSFTextStore ignores if SelectionChangeDataBase::mCausedByComposition or TextChangeDataBase::mCausedOnlyByComposition is true (for supporting async changes in e10s mode). So, only issue is, dropping the flag might cause increasing computing TextChangeData cost during composition in TSF mode. However, now, it's already enough fast and even if it'd cause performance regression, we could add a hack with TextComposition's offset information. Therefore, we don't need to worry about the performance regression so seriously.

Currently, all widgets request selection change notifications to IMEContentObserver. Additionally, IMEContentObserver needs to listen selection changes for caching latest selection for eQuerySelectedText. Therefore, it doesn't make sense to keep defining nsIMEUpdatePreference::NOTIFY_SELECTION_CHANGE.
If widgets didn't need selection change notifications, they could just ignore the unnecessary notifications.
Note that all widgets don't need selection change notifications if a plugin has focus and IMEContentObserver cannot observe selection changes in the plugin. Therefore, if IMEContentObserver is initialized with a plugin, it shouldn't listen selection changes (and doesn't need to notify widgets of selection changes).

While a TSFTextStore instance is being destroyed, TSFTextStore::Destroy() tries to commit remaining composition and notify TSF of destroying the view. At this moment, TSF/TIP may try to commit the composition or retrieve the contents with calling ITextStoreACP::RequestLock() but currently TSFTextStore disallows the requests to lock of them. This means that TSFTextStore never sends composition commit events asynchronously. Therefore, TextComposition may keep waiting remaining composition events but this causes odd behavior because they won't be fired.
For avoiding this issue, TSFTextStore should behave as normal even while it's being destroyed. Fortunately, if there is a composition, it always has mLockedContent and mSelection. So, it can compute expected results of TSF/TIP with them.

Some special keyboard layout may use a key as a non-lockable modifier key even if the key isn't a non-lockable modifier key (e.g., CapsLock key of 'Neo' for German). In such case, KeyboardLayout class cannot initialize NativeKey::mCommittedCharsAndModifiers with actual input character properly because KeyboardLayout class doesn't support such eccentric keyboard layouts.
For preventing this issue, NativeKey should overwrite mCommittedCharsAndModifiers with following WM_CHAR message when it handles WM_KEYDOWN and should handle with following WM_CHAR message.
