An apparatus and method for a graphical user interface allow performing operations simply by dragging a first object to touch a second object. The selection of the first object places a corresponding first object in a chain of objects. When the selected first object touches a second object, a corresponding second object is added to the chain of objects. This process may continue for the selection of many objects by merely touching each object with the selected first object, which causes a corresponding object to be added to the chain of objects. The chain of objects may then be processed as an atomic group of operations that may be rolled back if any of the operations in the group fail.

Transactional programming promises to substantially simplify the development and maintenance of correct, scalable, and efficient concurrent programs. Designs for supporting transactional programming using transactional memory implemented in hardware, software, and mixtures of the two have emerged recently. However, conventional debuggers do not provide features and capabilities that could be desirable for debugging programs executed using transactional memory. For example, conventional debuggers are not adapted to provide a coherent or consistent view of variables in a system that employs transactional memory. Because transactional memory implementations provide the “illusion” of multiple memory locations changing value atomically, while in fact they do not, there are challenges involved with integrating debuggers with such programs to provide the user with a coherent view of program execution. We describe techniques that employ transactional memory to allow a debug user to define a group of variables as an atomic group and to ensure coherent or consistent access to variables of the atomic group.
