Wow, that's pretty amazing. I wonder how it's implemented, and if there are any tutorials on implementing something similar, for programming language designers/creators.

Theres also Py Spy, a profiling tool that can generate flame charts containing a mix of python and C (or C++) calls.

It's worked really well for my needs

py-spy also makes it very easy to scrape from existing processes, which is invaluable if you are e.g. ever trying to diagnose a deadlock

I think it uses gdb's frame filter API: https://sourceware.org/gdb/onlinedocs/gdb/Writing-a-Frame-Fi...

GDB itself is fully scriptable in Python:
