Title: Methods and systems for recreating a program state.
Inventor: NATHAN RAYMOND MATTHEWS
IPC: G06F11/36
Filed: 2020-01-30
Abstract: Step counter values are associated with respective points in the progress of a program’s execution. Values assigned or used at a point are associated with the respective step counter value. A snapshot is generated by storing the values associated with a first step counter value. The state of the program at a subsequent point in the execution is recreated by recreating the program state from the snapshot and executing the program to the desired point using a log of non-deterministic values. Non-deterministic values may include the current time, data read from an external database and data retrieved via a network. Values may be associated with the step counter value associated with the points that the value was created, modified, inserted into an object and assigned to a stack frame. Multiple snapshots may be created corresponding to different points in the execution.
