- Various profiling utilities:
- Helper struct to simplify building a
string_tablefor the pprof format.
- Check whether symbolization has ever been run in this process. This controls whether we display a warning about increasing RAM usage due to the backtrace cache on the profiler page. (Because the RAM hit is one-time, we don’t need to warn if it’s already happened).
- Given some stack traces, generate a map of addresses to their corresponding symbols.
