Rhino Change Log
This is a log of changes since the release of Rhino 1.5 Release 3.Rhino debug API changes
A new, incompatible Rhino debug API gives an option to monitor entering/leaving of script functions while decreasing the amount of code to implement the API in the Rhino core. Details are available here. With the new API Rhino Debugger provides options to break on function enter/exit, can debug scripts defined by eval and Function construction and scripts loaded prior the debugger were started.WrapFactory introduced, WrapHandler deprecated
A design flaw in the WrapHandler interface (a call to a Java contructor from JavaScript would result in a call to wrap the result, which would then be cast to a Scriptable) inspired the deprecation of that interface and the introduction of a new class, WrapFactory, that contains a new method called on the result of a constructor call and can be customized by application if necessary.In addition, WrapFactory has the new setJavaPrimitiveWrap method to control if instances of Java String and Number class should be wrapped to special script objects as any other Java objects so a script can access any method String and Number, or they should be converted to JavaScript primitive strings and numbers.
New security interfaces
Igor Bukanov contributed a new security implementation that allows integration with Java2 security model and prevents scripts to escape the security sandbox via eval/Function schemes.
Due to this changes SecuritySupport interface is replaced by ClassShutter and SecurityController, where ClassShutter controls which classes are visible to scripts via LiveConnect and SecurityController provides permission management. For compatibility SecuritySupport is still available as a deprecated interface but only its visibleToScripts method is used as an alias for ClassShutter.visibleToScripts. See API documentation for new classes for details.
An implementation of SecurityController that uses java policy settings to restrict script permissions based on its URL is available with Rhino shell. See the JavaPolicySecurity source for details. To activate it, set the rhino.use_java_policy_security system property to true when invoking Rhino shell together with installing a security manager.
Serialization chages
Due to changes in Rhino implementation and bug fixes in serialization support runtime data serialized in Rhino 1.5 Release 3 can not be read back in the Release 4.Regular expressions improvements
Roger Lawrence provided new regular expressions implementation which fully confirms to EcmaScript 262 standard and faster.Scripting of classes from any class loader
Christopher Oliver contributed code to allow to use the Packages object as a constructor taking a class loader argument so a script can access classes defined by that class loader. For example, to access classes from foo.jar file in the current directory, the following can be used:
// create class loader
var loader = new java.net.URLClassLoader([new java.net.URL("file:./foo.jar")]);
// create its LiveConnect wrapper
var fooJar = new Packages(loader);
// create an instance of the class For from foo.jar
var obj = new fooJar.Foo(1, 2, 3);
obj.someMethod();
Shell function to run external processes.
A new runCommand function is added to Rhino Shell to run external priocesses. For details, see JavaDoc for org.mozilla.javascript.tools.shell.Global#runCommand.Resolved Bugzilla reports
