1. Targeting of labels with 0x80000000 biscuits is moved from LabelTable to ClassFileWriter as this is classfile specific and is not necessary in Interpreter.
2. LabelTable allows for pc > Short.MAX_VALUE as this restriction is classfile specific. The only requirement is for jump offsets to stay within short range.
3. LabelTable is made private member of Interpreter and ClassFileWriter instead of being classes' superclass to avoid API leakage that forced optimizer.Codegen to declare few utility methods public as they got the same signature as LabelTable methods visible throw Interpreter inheritance.
bug 139883, "ErrorHookProc can be tricked into thinking it never finished running", r=peterv
fixes bad early return in jsds_ErrorHookProc
test for correct max params (12, not 8) in CreatePPLineMap
use nsnull instead of 0 for null pointer return value
1. Replacing omj.debug.Debugger.enterFrame() by omj.debug.Debugger.getFrame() and omj.debug.DebugFrame.onEnter() to allow to return null from omj.debug.Debugger.getFrame to enable full optimization with debugger set if it is not interested in monitoring a particular frame
2. Changing type for the source argument in omj.debug.Debugger.handleCompilationDone from StringBuffer to String as Debugger instances should not be able to modify source even by chance.
The patch uses the special NOT_FOUND value to flag deleted indexes. It also
make sure that original array object passed to Function.call is not modified,
as all changes goes to cloned copy. It is not necessary for the fix, but it is
the only place in the current Rhino that can alter Object[] array passed to
Function.call and I think it is better to remove this exceptional case.
These changes add the cache optimization to the has methods and remove cache update from the put methods under the assumption that newly assigned properties would not be used immediately.
hi Norris,
in our product, which makes heavy use of Rhino, we have many Java Objects
we wrap with ECMAScript wrappers, which extend the ScriptableObject class
and implement the Wrapper interface. Those wrappers automagically wrap the
native Java object with the help of a WrapHandler implementation.
we now ran into a problem :
we have a java class with two overloaded static methods like this :
public class Test {
public static String create(File f) {}
public static String create(Custom c) {}
}
The Custom class exists as a native Java implementation like
public class Custom {}
and a accompanying ECMAScript wrapper like
public class CustomWrapper
extends ScriptableObject
implements Wrapper {}
in our ECMAScripts we make the wrapper class known as a host object along
the lines of
defineClass("CustomWrapper");
and can then use the object as a normal ECMAScript host object. no big deal
and working great.
but : the code
var s = Test.creat( new Custom( "xyz") );
fails with the information, that the methods are ambiguous, which of course
they are not.
Looking at the code of NativeJavaMethod.findFunction() and the helpers in
NativeJavaObject it seems, that the fact of the Custom host object being a
Wrapper is not taken into account. in an easy fix of
NativeJavaMethod.findFunction(), i simply replace all arguments, which are
Wrapper imlpementation by the wrapped object. this solves my problem, but
of course i'm not sure on side effects.
i attach the testcase as well as the fixed NativeJavaMethod class in the
jar file. to run the test with and without the fix, extract the jar and do
ant test
please let me know, what you think of this.
regards and thanks, f.
