&wintrace My time travel solution for Windows I'm developing can now index the entire execution of a recorded process to provide basic time travel controls: step forwards/backwards, rewind to start or end of the recording and jump to any position in the recording. The index contains process "keyframes" which define a differential memory state to the previous keyframes and jumping to a position chooses the nearest keyframe, executes from it until the position is reached and renders the full program memory pages on demand when the debugger asks for them. The replay engine and new controls are integrated with raddbg, and the session here is showing a recording of raddbg itself.
