ckb-vm-signal-profiler

Signal based profiler for ckb-vm. Like gperftools, it uses a SIGPROF signal handler to suspend running CKB-VM programs so as to gather profiling data. One advantage of this solution, is that it requires no code injections into CKB-VM. However also due to this design choice, this profiler runs on Linux only for the moment.

See here for an example on using this library.

This library inherits a lot of the signal handler related code from pprof-rs library.

Notes

• If anything weird happens when loading the generated profiling data, make sure you are using the golang based pprof at here, not the binary from gperftools with the same name.
