The code generator uses == and != to compare two instances of Class, but
it really should be using equals because two distinct instances of Class
can refer to the same class type.
Java allows a class field to have the same name as a superclass field,
but when we generate bindings for them, they'll end up with the same C++
name and cause an error. This patch makes the SDK processor filter out
any superclass fields that are hidden by a subclass field with the same
name.
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.
Right now, when we generate bindings for Java class A, and we encounter
a Java type B, we generate a corresponding C++ name only if A == B,
otherwise we generate a generic "jni::Object" C++ name. For example,
class Foo {
class Bar {
Foo getFoo(Bar bar);
}
}
In C++, Foo.Bar.getFoo would become,
class Foo {
class Bar {
jni::Object::LocalRef getFoo(Bar::Param bar);
};
};
This patch extends the code generator so that any Java class in the
chain of declared classes gets a corresponding C++ name. The above
example now becomes,
class Foo {
class Bar {
Foo::LocalRef getFoo(Bar::Param bar);
};
};

This commit is us getting out of our own way. We were specifying
-classpath twice, once in $(JAVAC) and once in java-build.mk. Only
the latter of these is active. This a problem for ANDROID_EXTRA_JARS
-- those JARs should be on the classpath and input to $(DX) -- and
JARs that should be on the classpath but *not* input to $(DX). This
commit removes the global flags to $(JAVAC) and adds
JAVA_{BOOT}CLASSPATH_JARS. This required some hijinkery moving
wildcards to moz.build files, but everything seems to work.
As well as clarifying some parts of the build, part 2 uses this work
to modify the classpath.

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.
To reduce verbosity of the generated code, this patch makes the code
generator use unqualified names when possible, e.g. use State::Ref
instead of GeckoThread::State::Ref. To accomplish that, function
prototypes now use the C++11 -> syntax for return types.
Currently, when we generate JNI wrapper for an inner class, the
resulting C++ class will not actually be a nested class of the enclosing
class. As a result, the class can be confusing to use. For example,
wrapping Java class GeckoThread.State results in two unrelated C++
classes, GeckoThread and State, and it'd be confusing to use State by
itself.
This patch adds support for inner classes. We start by scanning only for
top-level classes, and when processing each top-level class, we
recursively scan for inner classes through
JarClassIterator.getInnerClasses() and CodeGenerator.generateClasses().
For each Java inner classes, the resulting C++ class will be a nested
class. For example, wrapping GeckoThread.State will produce
widget::GeckoThread and widget::GeckoThread::State.
The API version detection functionality was broken in SDKProcessor
because we were passing in "Lpackage/Class;" as the class name rather
than just "package/Class". Also, some classes have a weird situation
where some methods were moved around in later API versions. For example,
some put* and get* methods in Bundle were moved to BaseBundle in API 21.
If we only checked BaseBundle.put*, we would think they are API 21+
only. The workaround is to check both the top-level class and the
declaring class for a member, and choose the lower API level as the
minimal API level for that member.
This patch also fixes bugs in including the right class members.
For SDKProcessor we want to include all public members of a class,
including inherited members, because the private/protected members are
not part of the public API. For AnnotationProcessor, we want to include
all the members declared in that class, including private and
protected members, because we may want to access private/protected
members of our own Java classes from C++.
In certain configurations, in particular when installing the Android SDK
using HomeBrew, one sees a configuration with symlinks like:
[brian@brian-macbook git]$ ls -l /usr/local/Cellar/android-sdk/23.0.2/
total 72
...
lrwxr-xr-x 1 brian admin 38 Nov 14 16:39 platforms -> ../../../var/lib/android-sdk/platforms
...
drwxr-xr-x 26 brian admin 884 Nov 14 17:43 tools
In this case, we have
ANDROID_SDK=/usr/local/Cellar/android-sdk/23.0.2/platforms/android-21.
It is an anti-pattern to use ANDORID_SDK/.. to find other paths in the
tree. This pattern is used in at least two places:
1) When we try to find
/usr/local/Cellar/android-sdk/23.0.2/platforms/android-21/../../tools,
we end up in the /usr/local/var/lib subtree. This patch works around
that by exporting and using ANDROID_TOOLS; ANDROID_TOOLS itself is
extracted using path matching, rather than following .. through the
filesystem.
2) We also need to use ANDROID_SDK_ROOT rather than
ANDROID_SDK/../.. through-out.

This patch adds AndroidBridge::HandleUncaughtException calls to generated JNI wrappers. Also, the JNI annotation now accepts the noThrow flag to indicate that the JNI caller wishes to handle Exceptions manually.
This writes source with preprocessed package names into
generated/org/mozilla/{firefox,firefox_beta,fennec,fennec_$USERID},
and the other preprocessed source into generated/org/mozilla/gecko.
This layout matches the Java package hierarchy and is what IDEs expect
when including $OBJDIR/generated as a source directory.
