IdFunction.java to use it. The code in BaseFunction to serve as
Function.prototype is not used yet. The patch modifies NativeCall so it
can be used against BaseFunction.

in fields of the object itself instead of using the standard property
hashtable in ScriptableObject.java. This saves 3 object instances per
NativeError (2 slot entries and hashtable array itself) and given the
fact that NativeGlobal defines a few permanent Error instances, it is
visible saving even after taking into account code size increase.
The change also gives a good test of IdScriptable implementation.

This patch introduces the uniform decompile method for NativeFunction
and IdFunction with the signature:
public String decompile(Context cx, int indent, boolean justbody)
instead of NativeFunction.decompile(int indent, boolean toplevel,
boolean justbody) and IdScriptable.toStringForScript(Context cx) and
replaces the special treatment of NativeJavaMethod in
NativeFunction.jsFunction_toString by overriding decompile in
NativeJavaMethod

Rhino: behavior update for IdScriptable subclasses

The attached patch introduces separation between id-base properties in
prototype instances and the rest of objects so it is possible to
allocate some ids for each instance and the rest only for prototype. The
patch adds to each descendants of IdScriptable a special prototypeFlag
which set to true only if object serves as a global prototype and all
methods that check/return ids first check for that flag. (This is the
reason for the patch size: diff is not very well in dealing with
indentation changes.)
In this way ids for prototype properties are completely hidden from
potential subclasses and there is no need to define methods like
getMaximumId in most cases, only if some ids present in each instance,
IdScriptable.maxInstanceId should be overridden to return max id present
in each instance.
The patch also replaces 2 boolean fields in IdScriptable by bit masks in
the setupFlag field.

Hello, I am trying to find a scripting language with an interpreter that I
can embed in an applet in order to run test scripts inside the applet. I
have already tried TCL-based Jacl and they do not support running inside an
applet. I then downloaded the Rhino/JS interpreter but am having trouble
getting it to run inside the browser (IE 5.5). Here is the exception I am
getting:

1. In that patch I forgot to remove "import org.mozilla.classfile.*" and
simply catch Exception in newInvokerMaster which is not a good practice.
The attached patch FunctionObject_patch fixes that and removes other
unused imports.
2. In org.mozilla.classfile.DefiningClassLoader defineClass method first
tries to call via ClassManager the defineClass method in a class loader
that loaded DefiningClassLoader itself. But this would define new
classes in that class loader so they would not be subject of the garbage
collection until a classloader that loads DefiningClassLoader would go
away even if a DefiningClassLoader instance is gone. The
DefiningClassLoader_patch removes that and simply calls super.defineClass.
The patch also change the order of class search in loadClass so the
loader first looks for a class among its defined classes and only after
that in parent loaders.

The update is pretty messy: it touches FunctionObject which I changed to
remove the special treatment of NativeWith in the previous patch, and it
also add/removes files.
Here is a description:
DefiningClassLoader.java should go to org/mozilla/classfile. It is the
same code that was in omj/optimizer/JavaScriptClassLoader.java with
class rename and adding public attribute and correspondingly
omj.optimizer/JavaScriptClassLoader.java should be removed. I guess it
would be nice to preserve logs/history in CVS during the move.
InvokerImpl.java should go to omj/optimizer. It is mostly what
omj.Invoker was.
invoker_changes_patch was generated via
cvs diff -u Invoker.java JavaAdapter.java optimizer/Codegen.java
and contains changes against the current CVS
FunctionObject_invoker_patch was generated via
diff -u ../../mozilla.1/javascript/FunctionObject.java FunctionObject.java
and contains changes against that With patch.
