Multi-threaded support?

[nckswt]

I'm generating and running a profile for a multi-threaded application using the following commands:

yappi -b -f pstat -o /tmp/script.prof script.py
snakeviz /tmp/script.prof

What I expect to see is the main loop function being called, along with any threads owned by the parent process. What I actually see is threading.py as the root function, and no calls to my main functions. I also can't tell if this is just profiling one of my threads, or all my threads.

Does snakeviz support pstat profiles from multi-threaded executables? Is there something I'm doing wrong? I've been going through whether yappi can generate multithreaded pstat profiles, but the documentation is.... sparse.

This is an interesting question and not one I've experimented with. If you have a profile you can share I'd be interested to play around with it. I suspect this is similar to #116, where there are multiple "root" nodes and snakeviz only picks one.

I think this applies to async as well!
