  • Call stacks for asynchronous programs
    Patent number: 9092564
    Abstract: Embodiments provide call stacks for asynchronous programming. A set of all asynchronous call stacks is found by first identifying all threads and all outstanding tasks that have not yet been completed. Optionally, all outstanding continuation-delegates or lambdas that are in the windows queue waiting to be scheduled and/or all outstanding delegates or lambdas in a language-specific queue are also identified. Next, for each thread, identify whether it was invoked by a continuation-callback and, if so, find the corresponding task/promise. Next, given a task/promise, identify the logical parent task/promise. Optionally, given a delegate or lambda, identify its logical parent task/promise. The sequence of logical tasks/promises constitutes an asynchronous call stack in a program. Further information may optionally be retrieved to make the asynchronous call stack more useful. Finally, given a task/promise, identify the corresponding line number and location in source code.

  • Asynchronous programming model mapping
    Patent number: 8539439
    Abstract: Mapping is performed between operations of an abstract asynchronous programming model and a concrete asynchronous programming model. In other words, differences between asynchronous programming models are bridged to enable interaction.
