  • System and method for bridging object systems
    Patent number: 7500252
    Abstract: A system and method is provided for bridging disparate object systems. The system includes a first wrapper to bridge communications between a first object system and a second object system and a second wrapper to bridge communications between the second object system and the first object system. The first wrapper insulates the first object system from interface implementations in the second object system and the second wrapper insulates the second object system from interface implementations in the first object system to facilitate transparent communications between the first and second object systems. The first object system may be at least one of a managed object system and an unmanaged object system, and the second object system may be at least one of a managed object system and an unmanaged object system.

  • Execution context infrastructure
    Patent number: 7458072
    Abstract: Described herein is an implementation for exposing an “execution context” to a logical execution flow of procedures as it executes. An “execution context” is a set of data and/or sub-procedures that might be useful at some point during a logical execution flow (to manage and control the execution flow and provide additional services to the execution flow) of computer-executable instructions though the often complex, intertwined, and interconnected conglomeration of procedures of software product(s).

  • Host control of partial trust accessibility
    Publication number: 20080282315
    Abstract: Various technologies and techniques are disclosed for providing host control of partial trust accessibility. A framework allows libraries to be identified as partial trust callers allowed to indicate that the libraries are allowed to be called from partially trusted code by default. The framework allows libraries to be identified as partial trust callers enabled to indicate the libraries could be called from partially trusted code, but not by default. A hosting application is notified that a particular library has been loaded. If the particular library has been identified as partial trust callers allowed, then a determination is received from the hosting application on whether to remove or keep partial trust accessibility for the particular library. If the particular library has been identified as partial trust callers enabled, then a determination is received from the hosting application on whether or not to enable partial trust accessibility for the particular library.

  • Runtime hosting interfaces
    Patent number: 7418718
    Abstract: Systems and methods for enhanced runtime hosting are described. In one aspect the runtime hosting interface includes a host abstraction interface. The HAI allowing the runtime to configure host execution environment parameters and/or notify the host of a runtime event. In particular, the host abstraction interface (HAI) corresponds to execution environment abstractions supported by a host application. Responsive to an action or event, the runtime invokes an identified HAI or an associated object during execution of runtime managed code.

  • Using code access security for runtime accessibility checks
    Publication number: 20080134310
    Abstract: Various technologies and techniques are disclosed that use code access security for providing runtime accessibility checks. A request is received from a first program to access at least one private member of a second program at runtime. If the first program has a greater than or equal security context than the second program, then the first program is granted access to the at least one private member of the second program. This code access security check can be provided in a framework environment that is responsible for managing programs that are from unknown or untrusted sources.

  • Using security-related attributes
    Publication number: 20070209073
    Abstract: Described is a technology including an evaluation methodology by which a set of privileged code such as a platform's API method may be marked as being security critical and/or safe for being called by untrusted code. The set of code is evaluated to determine whether the code is security critical code, and if so, it is identified as security critical. Such code is further evaluated to determine whether the code is safe with respect to being called by untrusted code, and if so, is marked as safe. To determine whether the code is safe, a determination is made as to whether the first set of code leaks criticality, including by evaluating one or more code paths corresponding to one or more callers of the first set of code, and by evaluating one or more code paths corresponding to one or more callees of the first set of code.

  • Transactions for an application domain manager

  • System and method providing inlined stub
    Publication number: 20060085460
    Abstract: A system and method is provided to facilitate communications between object systems. A caller is provided having optimized in-lined functionality when initiating a remote function call between managed and unmanaged object systems, for example. The in-lined functionality includes utilizing direct calls and returns within a calling function. In this manner, pushing additional arguments onto an execution stack because of an external stub reference is mitigated. In addition, one or more code loops can be analyzed to enable stack markers to be “hoisted” and thus pushed a single time instead of each time the calling function executes. Other aspects of the optimized caller provide garbage collection and thread management, security attribute checking on outgoing calls, calling convention considerations, wherein arguments and return values are organized according to the convention utilized by the remote object system, and in-lined marshalling to provide enhanced performance over external stub code references.

  • Transparent and sub-classable proxies
    Publication number: 20050268309
    Abstract: A system and method for interacting with an object is provided. The system includes a method call interceptor that intercepts a method call made on an object and that routes the method call to a proxy. The method call interceptor is accessible to application code. The system also includes an application code generic proxy that after overriding a base class invocation method can receive intercepted method calls, can invoke methods on the object that the proxy images, can receive results from the object that the proxy images and can pass results to the entity that generated the intercepted method call.
