Easy profiling option #1375

jcheng5 · 2024-05-14T05:32:12Z

The idea is to add --profile to your shiny run command, and that will run Shiny under py-spy, then launch speedscope with the resulting trace.

TODO

On Windows, sys.orig_argv has two executables in the argv array (python.exe and shiny.exe), we just need the second. Why?
Currently pass the profiling data to speedscope.app via URL hash, need to work around the limits of URL hash sizes.

I couldn't get py-spy working on Python 3.11 or later on Windows
