Detecting and identifying an interpreted language virus, such as a scripting virus, and reasonably identifiable polymorphs of the virus source code. Scripting virus source is extracted and represented in a language independent form. This form includes a linearized set of key actions, termed an executing thread, rather than the scripting source code. The executing thread can be utilized to generate a virus signature and virus pattern file for use in identifying the virus in later extracted scripting virus source code. Further the executing thread may be compared to existing virus signatures to determine the identity of the virus, if a match is made. The scripting virus scan engine detects reasonably identifiable polymorphs of a scripting virus source code that involve lexical and grammatical transformations, such as manipulation of white space, renaming of identifiers, and change of program layout.

Delivering data and formatting information includes delivering object definition files from a server to a client; generating definitions and object instantiations at a client using JavaScript or another simple browser-interpreted language, for objects relating to data modeling and presentation; and presenting data using those objects at the client, using a web browser without a separate runtime environment or application plug-in, but maintaining substantial state at the web browser regarding the data itself and the format for its presentation. Definition files are modified to provide object properties consistent with a full object-oriented language, including for example hierarchical inheritance of object properties. Code ballooning generates definitions and individual instantiations, with the effect that a very large amount of DHTML, or another markup or presentation definition language for use with the application, can be generated from relatively small aggregate size of definition files communicated from the server to the client.

Interpreted code modules configured to be executed within a virtual machine can be identified. Each of the interpreted code modules can be configured to interact with a native module such that dependency information for the native module can be programmatically utilized by each of the interpreted code modules. An abstraction module for the virtual machine written in the interpreted language can be established. The abstraction module can be configured to load an instance of the native module, wherein upon loading the instance of the native module the abstraction module is exposed to the dependency information associated with the instance of the native module. Each of the interpreted code modules can be configured to interact with the native mode module through the abstraction module. The abstraction module is configured to provide the dependency information associated with the instance of the native module to each of the interpreted code modules.

A system and method may employ, focused grammars to facilitate automated generation of computer programs. Such implementation of focused grammars enables a new form of symbolic regression referred to as generative programming or automated programming. The search through the space of possible programs may be guided by a streak search method in accordance with which identified candidate programs that improve on the current streak may be used to create focused grammars for directing an additional localized search. In some embodiments, candidate programs are generated by randomly traversing focused grammars from the starting rule, and subsequently through the grammars, until a complete candidate program parse tree has been constructed. Candidate programs may then be executed, for example, by an evaluator, which may employ an interpreter adapted for use in conjunction with a Stack Manipulation Language or other interpreted language.

Techniques for processing source code written in a traditionally interpreted language such as JavaScript, or another dynamic and/or interpreted language, are disclosed. In one example, compiled code associated with the source code is constructed and executed. An assumption on which a specific aspect of the compiled code is based (e.g., an optimization) is tested at a checkpoint of the compiled code. A roll over to fallback code is performed if the test indicates the assumption is not true.

Disclosed is a method, system and computer product for retrieving and parsing dynamic data at runtime by use of an interpreted language script that utilize Java and XML technologies. The interpreted scripting language uses a set of proxies, introspection and configuration to access and retrieve data elements that are in existence within underlying applications but not immediately available to the interpreter.

A system and method is provided to perform code handling, such as interpreting language instructions or performing “just-in-time” compilation using a heterogeneous processing environment that shares a common memory. In a heterogeneous processing environment that includes a plurality of processors, one of the processors is programmed to perform a dedicated code-handling task, such as perform just-in-time compilation or interpretation of interpreted language instructions, such as Java. The other processors request code handling processing that is performed by the dedicated processor. Speed is achieved using a shared memory map so that the dedicated processor can quickly retrieve data provided by one of the other processors.

A description file that includes multiple statements written in a customizable, tag-based interpreted language for processing data contained in the messages is disclosed. A data shaper translates and then executes each statement in the description file. The customizable, tag-based interpreted language, defines the operational behavior of the data shaper. The operational behavior shapes data contained in the messages to produce publishable matter suitable for online presentation.

A system and method for controlling execution of an interpreted language. Statements of the interpreted language to be executed by a script engine are intercepted by a protection module and control is passed to a script helper module that is asociated with the script engine. The script helper module establishes a secure communications channel with an authorization component and passes the statements and an authorization request to the authorization component. The authorization component sends a reply to the script helper module which either permits the script engine to execute the statement or cancels the attempted execution. When the script engine is loaded, a list is updated identifying the script engine. If a script helper module is not present for the loaded script engine, a boot-strap loader is called to load the script helper module. A special information block contains data as to the location of the interception points.

In one embodiment of the present invention an interpreted language, such as, for example, Java, is selectively optimized by partitioning the interpreted language code (98) into a plurality of blocks (80-83) based on the complexity of each of the interpreted language instructions. In one embodiment of the present invention, each of the plurality of blocks is identified as either a block to be compiled into native code (80-82) if the block is simple, or a block to be interpreted (83) if the block is complex. The compiled and interpreted blocks are appended to form in-line mixed code (99) that contains both native code (90-92) and interpreted language code (93). This mixed code is formed before run-time, so that no further compilation is required at run-time. A processing unit (102) may be used to execute the native code directly without the use of a Java VM (10), while also executing, in-line, the interpreted language code (93) which requires use of the Java VM (10) to interpret the Java bytecodes.
