Abstract: Deferred formula computation executes software containing a set of programmed formulas, wherein the set includes a first programmed formula defined in an associated dependency graph to be dependent on a result of a second programmed formula. A method may encounter a reference to the first programmed formula during execution of the software, wherein the reference is associated with deferred formula computation request program code in the executing software to obtain a result of the first programmed formula; identify during execution of the software the second programmed formula based on traversal within the associated dependency graph of the first programmed formula; compute a result of the second programmed formula during execution of the software; compute the result of the first programmed formula during execution of the software, and return the computed result of the first programmed formula in association with the reference to the first programmed formula.

Abstract: Threads operating in a computing environment often invoke service functions, such as methods of a programming library. Such invocations may sometimes cause a blocking of the thread, which may be protracted. A long pendency of the service function invocation and blocking of the thread may be acceptable in some operating contexts, such as the ordinary processing of the thread, but may be unacceptable in other operating contexts, such as while performing a function evaluation during debugging. Such blocking may be mitigated by redirecting a service function to an abort function if the service function is capable of blocking the thread and the thread is operating in a safe mode. The thread may then be permitted to execute, and the potentially blocking service functions may be avoided, resulting in a function evaluation abort (e.g., an exception) rather than a blocked thread and a failed debugging scenario.
