#155289 - String.prototype.XXX.length has some wrong values
#155291 - RegExp properties should be DontEnum
Plus fix for matching against RegEXp captures with undefined value.
I keep getting syntax errors with no line numbers as well.
That happens when I use Context.compileReader(..) to compile the script. The
DefaultErrorReporter will throw an exception with only the message and not the
line it happened on.
It is of course easy to workaround using your own error reporter, but I've
attached a patch to add on the line and source name so the DefaultErrorReporter
gives the similar output as EcmaError if that is wanted.

The implementation in the ICEbrowser does not use it as in rare cases where conversion from JSObject to/from JS type may be needed (like calling JSObject.getWindow from a script), it seems that WrapHandler (or similar modifications to pre Rhino 1.5R2 sources) and Wrapper are enough to cover all the cases.
> Yes, we should probably just remove the JSObject code. We added it early on when Rhino was first written and we thought we might need JSObject compatibility with the JS + Java implementation in Navigator 4.x. That's not important now, so we should just remove this code (which likely doesn't work at this point anyway).
given the following object :
----------------------------------------------
function SomeObject() {}
SomeObject.prototype.exec = function() {
var local = this.someField;
}
----------------------------------------------
i create an 'instance', set a field and call the exec method :
----------------------------------------------
var someField = "global field value";
var anInstance = new SomeObject();
anInstance.someField = "instance field value";
anInstance.exec();
----------------------------------------------
then the local variable 'local' in the exec() method is assigned the value
of the global 'someField' variable instead of the instance field value.
the problem seems to be in the ScriptRuntime.callOrNewSpecial() method,
which is called, because the parser treats the name 'exec' specially. in
this method the exec() method gets called with
return call(cx, fun, thisArg, args, scope);
where the 'thisArg' parameter really is the global this value instead of
the dynamic this value, which is in the jsThis variable and which would be
the one needed...
is it legitimate to replace the above call in callOrNewSpecial() with the
following line :
return call(cx, fun, jsThis, args, scope);
this seems to only happen for methods named 'exec', which are identified as
special in the NodeTransformer.isSpecialCallName() method.
any help is appreciated. thank you very much for your time.
kind regards,
felix
The attached patch adds support for debugging eval and Function code transparently. It changes omj.NativeGlobal and omj.BaseFunction to embed line number of origin of eval and Function scripts into source name and pass 1 as base line for script code. In this way a debugger implementation can treat eval and Function code in the same way as scripts loaded from some url while giving more information about error location in case of an error in eval code as the error source would contain both line number of eval origin and line number in eval code itself.
I chose to embed line numbers via patterns like
sourcefile#<line-number>(eval)
sourcefile#<line-number>(Function)
just to be able to to pass the constructed name to URL constructor if the original sourcefile is a valid URL but it is pretty arbitrary.
I have noticed that attempting to call a java method like this:
public void foo(String foo, Serializable bar)
{
// un-important details
}
from script using foo("foo", "bar"); fails because the second argument
is not deemed coercable to Serializable. A preliminary look at the
coercion code shows that no check is made in this case with
isAssignableFrom().
The to type is only tested against StringClass and ObjectClass (non
primitive case).
