Re:You say “cave dweller debugging”, I say debug logging by marginalia_nu on Friday May 06, 2022 @11:39AM (#31286445)
Depends on the program.

In critical systems, it's not unheard of to transaction log every input and every response to external requests, have strictly deterministic code, so that you specifically can replay or reconstruct a system state.

It's a pretty demanding way to build software, but you also get extremely resilient software as a result.
