    Abstract: An apparatus and method detect the use of stale data values due to weak consistency between parallel threads on a computer system. A consistency error detection mechanism uses object code injection to build a consistency error detection table during the operation of an application. When the application is paused, the consistency error detection mechanism uses the consistency error detection table to detect consistency errors where stale data is used by the application. The consistency error detection mechanism alerts the user/programmer to the consistency errors in the application program.

    Abstract: A computer-implemented method is presented for simulating an orientation change on a computing device in a test environment. The method includes: retrieving an orientation action from a test script, the test script defined in accordance with a scripting language and the orientation action specifying an angle of rotation to simulate; setting a value of a window orientation variable in a web browser, the value of the window orientation variable correlating to the angle of rotation specified by the orientation action; issuing a resize command to a window resize function supported by the web browser; and issuing a change orientation event to a rendering engine associated with the web browser.

    Abstract: A performance monitoring technique provides task-switch immune operation without requiring storage and retrieval of the performance monitor state when a task switch occurs and provides accurate performance monitoring information. When a hypervisor signals that a task is being resumed and the application privilege level has been entered, it provides an indication, which starts a delay timer. The delay timer is resettable in case a predetermined time period has not elapsed when the next task switch occurs. After the delay timer expires, analysis of the performance monitor measurements is resumed, which prevents an initial state, a state due to execution of the operating system or hypervisor, or a state remaining from a previous task from corrupting the performance monitoring results. The performance monitor may be or include an execution trace unit that collects branch information in a current program execution trace.

    Abstract: A device may receive an indication to perform a performance evaluation on program code. The device may partition the program code into multiple program code portions based on receiving the indication to perform the performance evaluation. The device may execute a first program code portion of the multiple program code portions. The device may determine that the first program code portion has finished executing, and may determine a performance characteristic associated with execution of the first program code portion based on determining that the first program code portion has finished executing. The device may execute a second program code portion, of the multiple program code portions, and may provide information that identifies the performance characteristic while the second program code portion is being executed.

    Abstract: A dynamic service module is embedded in an agent and able to add functionality to the agent. The service module may manage .jar files for execution by the agent. The service module may receive the .jar files, provide them to an agent for execution, and may perform other functions. The agent may perform obfuscation in order to translate the .jar files into a modified version which may be more compatible with a particular agent. Once execution of the .jar file is complete, the agent may remove the .jar file as well as all trace of the .jar file. For example, the agent may remove byte code instrumentation that was installed as a result of the .jar file.

    Abstract: An information processing apparatus comprises: an insertion unit that inserts, into a class file that corresponds to one application, a first bytecode for tallying information about a resource used by an object generated by execution of a bytecode that is included in the class file; and a tallying unit that, if an application generates an object, tallies information about a resource used by the object generated by the application, wherein the one application that has executed the first bytecode is identified by execution of the first bytecode, the one application thus identified and information about a resource used by a generated object are registered to a storage unit in association with each other, and the tallying unit tallies a resource usage amount for each application based on the information registered to the storage unit.
