Display class name ?

[ocervell]

Hi,

Would it be possible to have an option to display the class name when calling class / instance methods ?

Let me explain my use case for https://github.com/freelabz/secator:

I have a base class Runner and many derived classes that each have their own name (httpx, naabu, nmap, ...) and implement the yielder() function differently. My goal is to get precise profiling information about each of those derived classes.

In my flamegraph, I'm seeing the same function yielder take a lot of time, but I can't distinguish between the derived classes other than by the order they are run at.

pyinstrument gives me httpx.yielder, nmap.yielder, etc... which makes it easy to understand what's going on, but py-spy only gives me the function name. I like py-spy because it supports multi-threading, but without this feature I don't have a clear view on my app.

In PyPerf we've implemented "class name" by checking if the first arg of a function is called self / cls. If self, we deref the arg's type (and if cls we assume it's the type) and then we read the type's name. This is implemented here in BPF, and can be added to py-spy easily.
