  • System and method for sharing objects between applications in a virtual runtime environment
    Patent number: 8245205
    Abstract: The techniques and mechanisms described herein are directed at sharing objects between applications executing in a virtual runtime environment. The techniques include compiling a cpu-independent file to create executable instructions that are associated with an application that is executable in a virtual runtime environment. A constructor associated with a shareable class defined within the cpu-independent file is executed to create an instance of a shareable object. The shareable object is then persisted in a manner such that other applications executing in the virtual runtime environment may access the shareable object. The technique may be performed during pre-JIT compilation or just-in-time compilation of the cpu-independent file. The execution of the constructor is performed at a restricted security level that prevents access to changeable information when generating static data for the static members of the shareable object.

  • Class initialization method semantics
    Patent number: 7941793
    Abstract: A system and method for mitigating problems associated with automatic execution of initialization code is provided. The system includes an initialization method activator that can call a class initialization method at a pre-determined execution point. The system also includes a deadlock analyzer that can determine whether calling the initialization method will create a deadlock, and, if a deadlock is detected that can resolve such a deadlock. The system also includes a semantic analyzing component that can analyze a semantic type associated with the initialization method and a domain uniqueness analyzer that can analyze the uniqueness of the domain with which the class will interact, to facilitate determining where to place code that will check whether a class is initialized, and if the class is not initialized that will invoke the class initializing method.

  • HIERARCHICAL RESERVATION RESOURCE SCHEDULING INFRASTRUCTURE
    Publication number: 20090100435
    Abstract: Scheduling system resources. A system resource scheduling policy for scheduling operations within a workload is accessed. The policy is specified on a workload basis such that the policy is specific to the workload. System resources are reserved for the workload as specified by the policy. Reservations may be hierarchical in nature where workloads are also hierarchically arranged. Further, dispatching mechanisms for dispatching workloads to system resources may be implemented independent from policies. Feedback regarding system resource use may be used to determine policy selection for controlling dispatch mechanisms.

  • Method and system for program editing and debugging in a common language runtime environment
    Patent number: 7516441
    Abstract: A system and method of providing edit and continue support in a software program debugging environment. “Edit and continue” support allows a user (e.g., programmer and/or developer) to update the code and/or data structure(s) of an executing program while it is running. After the user has finished editing their code and resumes execution, an integrated development environment (IDE) propagates the edit(s) into a common language runtime (CLR) environment before continuing. Therefore, from the CLR environment's perspective, an edit is a block of intermediate language code (IL) and/or metadata that is inserted into a running process. Moreover, The IDE can facilitate: determining “legality” of an edit; building the edit; sending the edit to the CLR environment; and/or, facilitating the CLR environment switch execution to the edited code.

  • Strategy for referencing code resources
    Patent number: 7487498
    Abstract: A strategy is described for assisting a supplier in updating code without negatively impacting preexisting applications that may interact with the original or updated code. In this strategy, a resource is transferred from a first code module to a second code module. So that the applications that utilize the resource can continue to access this resource, the strategy adds forwarding information to a new version of the first code module. The forwarding information provides a note which shows the Common Language Runtime (CLR) where to find the specified resource when the code modules are executed.

  • Method and system for software program editing in common language runtime environment (CLRE)
    Patent number: 7367015
    Abstract: A method and system are disclosed for editing a software program in a common language runtime environment, wherein the software program has a source code component, an intermediate language component, and a native code component. The method comprises executing a first portion of the native code component, suspending execution of the native code component at a first point, and allowing a user to edit the source code component to create an edited source code component. The edited source code component is compiled using a source compiler to create an edited intermediate language component, and the edited intermediate language component is compiled using an intermediate language compiler to create an edited native code component. The edited native code component is then executed beginning at the point where execution was previously suspended.
