The two happening at the same time can lead to the APZ autoscroll being
cancelled due to APZ receiving a main-thread scroll offset update.
To achieve this:
- The content process assumes APZ is handling the autoscroll until
told otherwise.
- If the parent process knows APZ won't handle an autoscroll, it
tells the content process via its response to the Autoscroll:Start
message. This covers all cases where APZ doesn't handle the
autoscroll, except the case where APZCTreeManager itself rejects
the autoscroll and it lives in the compositor process rather than
the parent process.
- If APZCTreeManager rejects an autoscroll and it lives in the
compositor process, it sends an 'autoscroll-rejected-by-apz' message
to the content process.

This patch includes a bunch of somewhat related fixes, these are:
- Ensuring that when a mochitest calls SimpleTest.expectChildProcessCrash()
the harness will wait for the crashes to be recorded before deleting the
dump files. This involves a message round-trip between the content and
parent process so to minimize its performance impact on all the non-crashing
tests it is done only when required.
- As an additional optimization, the SimpleTest harness will not send a
message to the content process anymore whenever it receives an
ipc:content-shutdown event, instead it does it only for abnormal shutdowns.
- Manually fixing remaining mochitests causing crashes to wait for crashes to
be recorded before finishing and deleting the dump files.
- Modifying BrowserTestUtils.crashBrowser() so that it optionally does not
delete the dump files, this is useful for tests that submit their dumps and
thus delete them on their own.

ChildPrivileges is a leftover from the B2G process model; it's now
mostly unused, except for the Windows sandbox using it to carry whether
a content process has file:/// access.
In general, when sandboxing needs to interact with process launch, the
inputs are some subset of: the GeckoProcessType, the subtype if content,
various prefs and even GPU configuration; and the resulting launch
adjustments are platform-specific. And on some platforms (e.g., OS X)
it's all done after launch. So a simple enum used cross-platform isn't

Therefore, the event order between keyboard events and composition events (and

compositionend event accidentally.
This patch gives same priority to composition events and selectionset event

can be determined, it appears as if the content process references
are what are keeping it alive. The shutdown of CompositorBridgeChild

what is keeping the thread alive. As such, this patch adds an

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.

This patch adds a preference jsloader.shareGlobal that makes it so
that JSMs share a single global, in order to reduce memory usage. The
pref is disabled by default, and will be enabled in a later bug. Each
JSM gets its own NonSyntacticVariablesObject (NSVO), which is used for

For the module loader, the main change is setting up the shared

from the shared global, because they do things to the global that
would interfer with other JSMs. This is detailed in

NO_REMOTE_TYPE seems to have been an artifact of introducing remote types and
not wanting to change things. This eliminates the type, changing
GetNewOrUsedBrowserProcess() to no longer use a default argument so that
callers must think about the remote type they want. Additionally, the existing
call-site used by xpcshell in nsEmbedFunctions.cpp is updated to use the
DEFAULT_REMOTE_TYPE of "web", as-is the unused nsAppRunner.cpp case. (That is,
no one appears to call nsXULAppInfo::EnsureContentProcess directly or via its

In some unknown circumstance, possibly if the parent process has a
different version than the child process, the child does not receive
scheduler prefs, which makes it read out of an uninitialized local
variable. This can probably happen because the scheduler prefs are
checked before we do the ContentChild::Init version check. Bill also
suggested that the pref env var might be getting truncated.
This patch improves on the situation by using null for the prefs array
if none was sent, and falling back on the default values, which leave
the scheduler disabled.
This also checks that the pref string is at least long enough to avoid
a buffer overflow. Note that if the end of the string isn't an integer
we'll end up with an sPrefThreadCount of zero, which can't be good.

These are all easy cases where an nsXPIDLCString local variable is set via
getter_Copies() and then is only used in ways that nsCStrings can also be used
(i.e. no null checks or implicit conversions to |char*|).
In every case the patch trivially replaces the nsXPIDLCString with an
nsCString. (Also, there are a couple of unused nsXPIDLCString variables that
the patch simply removes.)
This patch refactors the nsThread event queue to clean it up and to make it easier to restructure. The fundamental concepts are as follows:
Each nsThread will have a pointer to a refcounted SynchronizedEventQueue. A SynchronizedEQ takes care of doing the locking and condition variable work when posting and popping events. For the actual storage of events, it delegates to an AbstractEventQueue data structure. It keeps a UniquePtr to the AbstractEventQueue that it uses for storage.
Both SynchronizedEQ and AbstractEventQueue are abstract classes. There is only one concrete implementation of SynchronizedEQ in this patch, which is called ThreadEventQueue. ThreadEventQueue uses locks and condition variables to post and pop events the same way nsThread does. It also encapsulates the functionality that DOM workers need to implement their special event loops (PushEventQueue and PopEventQueue). In later Quantum DOM work, I plan to have another SynchronizedEQ implementation for the main thread, called SchedulerEventQueue. It will have special code for the cooperatively scheduling threads in Quantum DOM.
There are two concrete implementations of AbstractEventQueue in this patch: EventQueue and PrioritizedEventQueue. EventQueue replaces the old nsEventQueue. The other AbstractEventQueue implementation is PrioritizedEventQueue, which uses multiple queues for different event priorities.
The final major piece here is ThreadEventTarget, which splits some of the code for posting events out of nsThread. Eventually, my plan is for multiple cooperatively scheduled nsThreads to be able to share a ThreadEventTarget. In this patch, though, each nsThread has its own ThreadEventTarget. The class's purpose is just to collect some related code together.
One final note: I tried to avoid virtual dispatch overhead as much as possible. Calls to SynchronizedEQ methods do use virtual dispatch, since I plan to use different implementations for different threads with Quantum DOM. But all the calls to EventQueue methods should be non-virtual. Although the methods are declared virtual, all the classes used are final and the concrete classes involved should all be known through templatization.

When creating new windows/tabs from the content process, we currently choose
the default remote type based on the referrer URI, rather than the actual
remote type of the opener. While this generally works, it fails when opening
windows from URLs (particularly in iframes) which are opened in process types
other than their default process type, since the initial about:blank load gets
redirected to a new process before the child process has a chance to load its
actual target URI.
Using the actual remote type of the child opening the window fixes this
problem for URLs which are capable of being loaded into the child's process
type.

In all of these cases the fixed buffer has the same lifetime as the string
object, so we can use nsAuto[C]String for simplicity.
For the 128-length ones in dom/xul/ I just switched to the default of 64 for
simplicity, because the choice of 128 didn't seem that important. (These code
paths weren't hit when I started the browser and opened a few sites.)
Finally, the patch also changes LoggingIdString to use

This patch also eliminates undocumented b2g-era legacy logic that had a
notion of whether it's acceptable to override the process name. In the
b2g era, I believe processes were named based on the "app" that was
running. It would have made sense to have the process initially named
the preallocated process, then to change the process to its app name
when specialized, trying to make it hard/impossible for the process to
rename itself so it couldn't masquerade as another app if it became

Android now supports telling an IME that it shouldn't store user-entered content into it's dictionary/language model/etc. and we want to automatically enable this in private browsing.
As the code that handles input on Android doesn't have any notion of tabs (and therefore of the difference between normal and private tabs), the best way to get that info across is to retrieve it directly within the IMEStateManager from the corresponding document and store it in the inputContext, which is then passed to Java for Fennec to handle.
Implementing this within Gecko also has the benefit that this part of the code can be used by other platforms as well should they want to support similar features in the future.

process. Whenever the blocklist is changed, just resend the whole
plugin list.

The current code is wrong in several ways when transforms are applied, but
even if it were correct, it would give the wrong behavior. See comment in
patch for more details.

On-screen coordinates for points in remote frameloads are calculated relative
to the screen origin of the top-level window, while event coordinates are
calculated relative to the nearest widget. Since popups have their own widgets
separate from the top-level window, their native client offsets have no
particular relation to the origin of the top-level window, and we need to
manually calculate them relative to the origin of the top-level widget
instead.

On developer builds, use $MOZ_DEVELOPER_OBJ_DIR to whitelist the object dir in the content sandbox so that symlinks to the object dir from .app/ files can be loaded.

Currently, access key is handled in EventStateManager::PreHandleEvent() with eKeyPress event, i.e., before dispatching it into the DOM tree, if the access key is registered in EventStateManager. So, the main process does not check if the preceding eKeyDown event is consumed in focused remote process.
When preceding eKeyDown event is consumed in the main process, eKeyPress event won't be dispatched by widget. However, if remote process has focus, it's impossible widget to stop dispatching eKeyPress event because preceding eKeyDown event hasn't been handled in the focused remote process yet. Therefore, main process needs to post eKeyPress event to check if preceding eKeyDown event was consumed. When eKeyPress event is marked as "waiting reply from remote process", TabChild sends it back to the main process only when preceding eKeyDown event wasn't consumed. So, only when eKeyPress event is back to the main process, main process should handle accesskey with it.
This patch makes EventStateManager::PreHandleEvent() check if a remote target has focus before handling accesskey. If a remote process has accesskey and there is an accesskey matching with eKeyPress event, it marks the event as "waiting reply from remote content" and stop propagation in the process.
Finally, when eKeyPress event is sent back to TabParent, TabParent::RecvReplyKeyEvent() calls EventStateManager::HandleAccessKey() before dispatching the reply event into the DOM tree.

EventStateManager checks if every keypress event's modifiers match with access key modifiers which are in prefs. Moving related methods of this to WidgetKeyboardEvent makes EventStateManager simpler and we can hide the NS_MODIFIER_* constants (they may make developers confused between Modifiers of WidgetInputEvent) into WidgetEventImpl.cpp.

We should not let the ppm to do work before the first paint in a new cp. This patch
makes sure that we only let the ppm spawn a new process after the last process reached
an idle state AND the main process becomes idle too.
IME should receive notifications and requests only from proper process. E.g., IME shouldn't commit composition by a request which came from previous focused process.
This patch makes that IMEStateManager::NotifyIME() takes pointer to TabParent optionally. If the request or notification came from remote process, it should be non-nullptr. Then, this makes it ignore notifications and requests from unexpected process.
Note that this patch also touches some gfx headers because they use |ipc::| but compiler is confused at the ambiguousness between |mozilla::ipc::| and |mozilla::dom::ipc::|.
Finally, this patch changes the NS_ASSERTION in IMEHandler::OnDestroyWindow() to MOZ_ASSERT because the orange caused by the NS_ASSERTION was not realized since there was already an intermittent orange bug caused by different NS_ASSERTION.

This extracts a BaseMatrix template of which Matrix is now a particular
specialization. The BaseMatrix allows us to reuse the same code for
floats and doubles, much like the other "base" classes (BasePoint,
BaseRect, etc.).
