Exposing memory-backed objects as queryable memory resources

Abstract:

This disclosure relates to the use of execution traces to process queries against objects over their lifetime. Embodiments identify, from a trace, a memory-backed object that existed during a prior execution of an entity. A handle for logically representing memory covered by the object over the object's lifetime is identified. A plurality of associations that are represented by the handle are identified. These associations identify memory addresses that were covered by the object over its lifetime. Each association represents at least (i) a memory address that was covered by the object during its lifetime, and (ii) an execution time during the object's lifetime at which the memory address was covered by the object. A query is processed against the handle. The query includes a query based on an execution time, and processing the query includes comparing the execution time in the query to execution time(s) represented in the associations.
