摘要： 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.

摘要： Particular portions of program execution data are specified and organized in semantic groups. A grouping expression written in a transformation syntax language specifies a pattern and a replacement, for grouping performance data samples. An exception to the pattern can also be specified. In response to the grouping expression, a cost accounting shows groups and their costs. The grouping expression may operate on names and/or name-associated characteristics such as private/public status, author, directory, and the like. Samples may represent nodes in a directed acyclic graph memorializing call stacks or memory allocation. Grouping expressions are used to group nodes and consolidate costs by various procedures when making modified sample stacks: clustering-by-name, entry-group-clustering, folding-by-name, a folding-by-cost. An entry group clustering shows at least one entry point name while avoiding unwanted detail.

摘要： A profiler may be detached from an actively running application by first sealing communications between the application and profiler, then evacuating the profiler by waiting for any profiler-modified or instrumented code to complete execution, profiler runtime code to complete execution, cleaning up any residual items from the profiler, and shutting down the profiler. The profiler may be operational in many different environments, including a managed environment such as a virtual machine and those environments having just in time compiling of executable code.

摘要： Example embodiments provide for effectively executing a stack-walk and other operations by dynamically accessing information about the expected location of cookies on a stack. For example, a first function is executed that causes a stack-walk operation to occur. While performing the stack-walk operation, cookie location information for a cookie placed on the stack by a second function different from the first function is accessed. The cookie, if uncorrupted, includes a known value that is used to determine if the stack has been corrupted. Based on the cookie location information, corrupt data representative of the cookie is accessed. A global cookie, which also includes the known value, is also accessed. The known value of the global cookie is then compared with the corrupt data to determine that the stack is corrupted at least up to the location of the corrupt data representative of the cookie.

摘要： 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.

摘要： The subject disclosure pertains to systems and methods for supporting null capabilities for general purpose programming languages. Low level, runtime support for a nullable type is provided to ensure consistency and coherency. An execution component restricts support of the nullable type to programming language types that lack a null capability. The execution component may also provide support for conversion between the nullable type and a reference type.

摘要： A system and method for facilitating cross-process access into a managed code process is useful in an embodiment of the invention for debugging managed code without perturbing the process being accessed or requiring the code under test to be running during debugging. A compiler according to an embodiment of the invention is used to produce mirror code wherein in-process pointers have been replaced with cross-process pointers in order to mirror the address space of the process under test to the address space of the mirror code process. In a further embodiment, the mirror code process is modified not only to allow but also to optimize the cross-process access.
