Daisy Seminar: Debugging With Record/Replay
Gustav Wibling, VMware
Friday, November 23, 1PM, in 0.1.95 (Auditorium)
We are going to demonstrate how Record/Replay technology can be use to analyze difficult software problems: memory corruption, race conditions (including race conditions in network applications), etc.
The Record/Replay technology allows the user to efficiently record the execution of the virtual machine and then replay it with instruction-level precision. This makes all bugs 100% reproducible and enables debugging techniques that were not feasible before.
There will be a few demos: one will demonstrate basic record/replay on Windows, one will show more advanced use, and will show how record/replay can be used for Linux application debugging. We are going to explain how recording of software running in production allows doing correctness inspection and forensics research – with no downtime.
