This patch implements a new key event handler in nsWindow to replace the
previous implementation.
nsWindow::HandleSpecialKey was removed because it's a relic from XUL
Fennec and I believe we no longer need it for native Fennec.

Right now we don't allow quitting Fennec when the last nsWindow closes
(e.g. when the last GeckoView is destroyed) because we want to keep the
Gecko thread running throughout the app process lifetime. However, when
we are asked to quit explicitly through nsIAppStartup::Quit, we should
release the hold on nsAppStartup and allow quitting to continue.
The GeckoEditable instance doesn't change for each nsWindow instance.
However, because a GeckoInputConnection is associated with a GeckoView,
when we create a new GeckoView, we need to attach a new
GeckoInputConnection to the existing nsWindow's GeckoEditable. This
patch makes us do that inside nsWindow::Natives::Open by calling
GeckoEditable.OnViewChange.
This patch removes the GeckoEditable code in GeckoAppShell, and make
nsWindow create a GeckoEditable for itself when opening a window.
Instead of calling GeckoAppShell, nsWindow can now call GeckoEditable
methods directly.
We try to generate a C++ constant for static final fields, but that
was failing for inaccessible fields. Now we set the field to be
accessible so that we do end up generating a C++ constant.
The PROCESS_OBJECT GeckoEvent is used to set the layer client object in
Gecko once Gecko is done loading. This patch converts it to a native
call in GeckoView.Window.
This patch adds a specialization for jni::Ref<jni::ObjectArray>, which
includes members for getting the length of the array and accessing
array elements.
We have a pretty messy system of coalescing viewport events that
introduced a race condition during the recent JNI refactoring. This
patch makes that code simpler and fixes the race condition. Instead of
keeping track of a previous viewport event, we now scan the event queue
for previous viewport events. This shouldn't be a perf concern because
we only scan the queue for viewport and native callback events, and stop
scanning as soon as we find another kind of event.
This patch adds a specialization for jni::Ref<jni::ObjectArray>, which
includes members for getting the length of the array and accessing
array elements.
gfxIntSize is just a typedef of gfx::IntSize, so this is very mechanical. The
only tricky part is deciding for each occurrence whether to replace it with
IntSize, gfx::IntSize or mozilla::gfx::IntSize; in all cases I went with the
shortest one that worked given the existing "using namespace" declarations.
Originally, the GeckoThread PROFILE_READY state was chosen to correspond
to the profile-do-change event, to give priority to JNI code (e.g.
window creation) over other events that may be registered under
profile-after-change event. However, this leads to broken tests because
our testing infra expects things like window creation to happen during
profile-after-change at the earliest. This is because we have to wait
for addons like SpecialPowers to be loaded between profile-do-change and
profile-after-change. This patch changes the PROFILE_READY state to
correspond to the profile-after-change event, so things are consistent
again.
A C++ class that implments native JNI methods can choose to inherit
UsesGeckoThreadProxy. Once enabled, all native JNI calls on that class
will be automatically dispatched to the Gecko thread as a runnable event.
nsWindow will implement native methods of GeckoView.Window. This patch
implements the open method, which opens a new window in the same manner
as the CLH, and associates the new nsWindow with the GeckoView.Window
instance.
GeckoView.Window is a class that acts as the interface between
GeckoView in Java and nsWindow in C++. It will contain native methods
that GeckoView will use to interact with nsWindow.
On initialization, Window.open is called to create a nsWindow and
establish the JNI association between Window and the native nsWindow.
Then, whenever Window instance methods are called, the JNI stubs will
automatically call members of nsWindow.
With the new nsAppShell event loop based on runnable events, we need to
implement AndroidGeckoEvent handling as a runnable event. This patch adds
nsAppShell::LegacyGeckoEvent and adopts its implementation from existing
code that handle AndroidGeckoEvent.
nsAppShell is currently based on AndroidGeckoEvent objects, which mirror
GeckoEvent on the Java side. With GeckoEvent going away, we will be
gradually removing AndroidGeckoEvent as well. This patch makes the
nsAppShell event loop based on runnable objects, which derive from
nsAppShell::Event. Using runnable objects is much more flexible and allows
us, for example, to post a lambda to the event loop to be run later.
Gecko on Android follows the Android app model where it never stops
until it is killed by the system or told explicitly to quit. Therefore,
we should exit Gecko when there is no window or the last window is closed.
With this patch the ZoomConstraintsClient updates get broadcast via the observer
service on Android, allowing code in browser.js to switch over to using it.
The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.
If a C++ class implements native calls that all return void, it can
choose to have those calls go through a custom proxy function by
inheriting from mozilla::jni::UsesNativeCallProxy and override the
ProxyNativeCall member.
ProxyNativeCall accepts a rvalue reference to a
functor object specific to each call, and can alter the calling
environment (e.g. dispatch the call to another thread) before issuing
the actual native call through the functor's operator().
Any JNI refs contained in the call are automatically turned into global
refs so that the call can continue to work outside of the original JNI
call.
Native call proxy will be used to implement automatic dispatching of
native calls from the main thread to run on the Gecko thread.
This patch fixes a compile error when using WeakPtr, where Impl* was
expected but SupportsWeakPtr<Impl>* was given.
This patch also fixes a compile error when using the DisposeNative
implementation provided by the autogenerated Natives class. e.g.,
> struct Foo : Bar::Natives<Foo> {
> using Bar::Natives<Foo>::DisposeNative;
> };
This uses a default implementation of DisposeNative instead of a custom
implementation, and resulted in a compile error that this patch fixes.
The mangled name of a NativeStubImpl instantiation is longer than
necessary because of the ReturnType arg. This patch turns it into a bool
parameter. It also reorders the parameters for cleanness.
Add more constructors in LocalRef and GlobalRef to accommodate use cases
where a JNIEnv is already available for performance reasons. Also add
more null-checks when creating references for performance reasons.
One thing we do in the Fennec CLH is to make a speculative connection
based on the URI that's passed in. However, by the time the CLH runs,
we're far along into startup, and the advantage of a speculative
connection is reduced. This patch implements making speculative
connection as a method in GeckoThread, so that Fennec can make a
speculative connection without relying on the Fennec CLH.
Many Gecko operations depend on the profile being available. This
patch adds a PROFILE_READY Gecko state so that we can queue calls
until profile is loaded.
clang doesn't like it when we declare things as a struct in one place
and a class in another. This change makes all the current usages
consistent and clang happy.
GeneratedJNIWrappers.h was updated in bug 1192079 to use inherited
constructors, which is a gcc 4.8 feature. Many people are still using an
older version of NDK which only comes with gcc 4.7.
First we need to set the Gecko thread JNIEnv* in nsAndroidStartup, but
after that we can initialize and deinitialize the rest of JNI, including
AndroidBridge, in GeckoAppShell. This makes nsAppShell control the
AndroidBridge lifetime. Over time, parts of the AndroidBridge
functionality will be migrated to nsAppShell.
Merge all the init code into AndroidBridge constructor and
AndroidBridge::ConstructBridge; merge all the deinit code into
AndroidBridge destructor and AndroidBridge::DeconstructBridge.
In particular, the SetMainThread call is obsolete and removed.
Make NativeJSContainer/NativeJSObject Java objects own their
corresponding C++ objects directly, to reduce an extra
allocation/deallocation for each object and to simplify code.
Add a direct ownership model where the Java object owns the
corresponding C++ object directly, in addition to the WeakPtr model
where the Java object owns a WeakPtr to the C++ object. The WeakPtr
model is chosen when the implementing C++ class inherits from
SupportsWeakPtr. Otherwise, the direct ownership model is chosen. Under
the direct ownership model, a UniquePtr object must be used to attach
the containing C++ object to a Java object, to ensure ownership is
passed on to the Java object.
This patch adds:
* Conversion operator from String::Param to String::LocalRef.
* More overloads of the jni::ThrowException function.
* name members to built-in types like jni::Object, jni::String, etc.
This allows using jni::Accessors::EnsureClassRef on built-in types
to get built-in class refs (e.g. jclass for java/lang/String).
* Ability to implicitly convert LocalRef<Cls> to LocalRef<Object>
* Fixes for bugs in LocalRef/GlobalRef where new refs are not created.
* Fixes for inaccurate uses of mozilla::Forward in favor of mozilla::Move
This patch transforms RestrictedProfiles to delegate isAllowed() and
canLoadUrl() calls to an object implementing the RestrictionConfiguration
interface.
DefaultConfiguration, GuestProfileConfiguration and
RestrictedProfileConfiguration are implementing RestrictionConfiguration
and will take care of handling the restrictions for the different types
of profiles.
Add Bundle to the list of SDK classes to generate JNI bindings for. The
generated bindings, like other SDK classes, use XPCOM-style nsresult
to indicate success/failure, and return values through out-parameters.
We use Ref::From() inside TypeAdapter<Ref>::ToNative to convert a raw JNI
ref argument to a Ref argument for the C++ function. However, that
generates a compile error, unless we make TypeAdapter<Ref> a friend of
Ref, because we intentionally made Ref's copy constructor private and
returning from TypeAdapter<Ref>::ToNative requires the copy constructor.
Introduce a JNIObject class that serves as a base class for classes
that wish to use per-instance native methods. JNIObject includes a long
native pointer field that the C++ code accesses to associate the Java
object instance with a C++ object instance.
