Abstract: An abstract component model can be used to drive an editor by providing an underlying stateful model for component implementation without the need to re-implement details, such as event listening, lifecycle and update management, etc. An implementation needs to provide objects that make up the model, some logic to listen to environmental changes and recognize when an update is needed, and a builder which can generate a lightweight version of the model based on the current “state of the world.” In addition, abstract component model is operable to support an editor such as page flow.

Abstract: Prefetching irregular memory references into a software controlled cache is provided. A compiler analyzes source code to identify at least one of a plurality of loops that contain an irregular memory reference. The compiler determines if the irregular memory reference within the at least one loop is a candidate for optimization. Responsive to an indication that the irregular memory reference may be optimized, the compiler determines if the irregular memory reference is valid for prefetching. Responsive to an indication that the irregular memory reference is valid for prefetching, a store statement for an address of the irregular memory reference is inserted into the at least one loop. A runtime library call is inserted into a prefetch runtime library for the irregular memory reference. Data associated with the irregular memory reference is prefetched into the software controlled cache when the runtime library call is invoked.

A plurality of artifacts associated with the collaborative product development is maintained under revision control in a first repository. Each artifact has a plurality of lifecycle states and each artifact is associated with a first finite state machine (FSM) that defines lifecycle state transitions for the artifacts. A plurality of artifact tuples associated with the collaborative product development is maintained under revision control in a second repository. At least one artifact tuple is comprised of at least one access information providing access to at least one of said plurality of artifacts in the first repository. Each artifact tuple has a plurality of lifecycle states and each artifact tuple is associated with a second finite state machine (FSM) that defines lifecycle state transitions for the artifact tuples.

Abstract: A system-created variable object may expose a property of an object model to an internal object that does not have access to the object model directly. The system-created variable object may provide a mechanism for communicating the external state of an object model to an internal member (object) without exposing the object model to the internal object. This feature enables an object model object to be isolated, a concept that can be advantageously exploited.

Abstract: Computer program testing after source code for the computer program has been modified is performed more quickly, by using execution conditions. First, second, and third execution conditions are determined. These execution conditions are used to perform testing of the program to determine whether the program is properly functioning. Particularly, test data on which basis testing of the computer program is performed can be classified as first test data, second test data, third test data, or fourth test data. The program prior to modification of the source code is tested by employing the first, second, and third test data. After the source code is modified, the program is retested by employing only the third and the fourth test data. The program is thus properly retested after source code modification by employing only the third and the fourth test data, without having to employ the first and the second test data.

Abstract: Compiler device for optimizing program which manipulates a character string includes append instruction detection unit, store code generation unit, and append code generation unit. The append instruction detection unit detects an append instruction which appends a character string to a string variable for storing a character string, in the program. The store code generation unit generates, a substitute for each of a plurality of the append instructions detected by the append instruction detection unit, a store code for storing data of an appendant character string to be appended to the string variable by the append instruction into a buffer. The append instructions append the character strings to the same string variable. The append code generation unit generates append code for appending a plurality of the appendant character strings to the string variable, at a position executed before an instruction to refer to the string variable in the program.

Abstract: A system, method, and program product is provided that has a virtualized environment provided by a hypervisor. In the virtualized environment, one or more guest operating systems operate simultaneously with a privileged operating system. One of the guest operating systems identifies a device software update, such as a device driver or firmware update, corresponding to a hardware device that is attached to the computer system. The hypervisor is used to notify the privileged operating system of the device software update. When the privileged operating system is notified of the update, the privileged operating system uses one or more techniques to deny the guest operating systems access to the device. The privileged operating system then updates the device software update. After the device software update has been applied, the privileged operating system resumes access between the guest operating systems and the hardware device.

Abstract: Some embodiments of the present invention provide a system that tests a software program. During operation, the system creates a behavioral model of the software program using branches, decisions, and options. Next, the system applies a weight assignment technique to the behavioral model to create a set of global identifiers (IDs), which correspond to test cases of the behavioral model. The system then generates a test case from the behavioral model and executes the test case on the software program. Finally, the system analyzes an output of the executed test case to determine a validity of the software program.

Abstract: A method and system for inconsistency resolution in a model-driven software development environment are provided. A method includes performing a safety analysis for resolutions in response to detected inconsistencies to determine whether the resolution, if implemented, will lead to a resolution cycle when applied to a given inconsistency. The determination includes processing a resolution tree for the inconsistency and, using a resolution strategy tree, for each resolution that resolves an inconsistency, analyzing whether beginning with the resolution, it is possible to resolve all the inconsistencies subsequently introduced as side effects without a resolution cycle occurring. The analysis includes traversing the resolution strategy tree, whereby all resolution strategies derived by traversing the resolution strategy tree lead to a resolution cycle if the resolution strategy tree is infinite.
