Abstract: Service endpoints that provide services to client devices send registration data to a service directory service. The registration data includes addresses that client devices can use to access the service endpoints along with descriptive data that describes the services that each endpoint provides, along with other information such as version numbers of applications that are supported by the service endpoints, and whether the service endpoints are running an experiment. Client devices request a manifest from the service directory service. Each request includes client metadata that describes the requesting client device. The service directory service uses the registration data and the client metadata to generate a manifest for the client device that identifies the services that the client may access and an address that the client may use to access each service.

Abstract: Code morphing includes rewriting at least one underlying control structure of known code without affecting an intended context of the code.

Abstract: A method and system is provided for instrumenting a program by optimizing probe insertion. The number of probe insertions into instrumented code is reduced by providing optimal probe insertion points. The control flow of the code is analyzed along with the arc and block relationships to build a post-dominator tree. An optimization map is generated from the post-dominator tree that provides the optimal probe insertion points. Once the probes are inserted and data is collected by running the binary representing the code and probes, the data may be overlaid onto the optimization map and arc and block relationships to provide code coverage data.

Abstract: An exemplary media implementation precipitates a device to perform actions including: determining if an instruction of a line of common intermediate language (CIL) code meets a predetermined exception-related criterion; and if so, injecting a decision point in association with the instruction of the line of CIL code, the decision point enabling a decision as to whether an exception is to be thrown with respect to the instruction. An exemplary device implementation includes: instrumented CIL code that includes a test couplet corresponding to a decision point and an associated instruction, the associated instruction capable of causing a fault; a decision runtime library that is adapted to evaluate the test couplet to selectively decide whether to throw an exception with respect to the associated instruction; and a common language runtime component that interprets the decision point so as to call the decision runtime library prior to executing the associated instruction.
