π€ *The coolest feature in Python 3.14: sys.remote_exec() by Savannah Ostrowski*
π https://ep2026.europython.eu/session/the-coolest-feature-in-python-3-14-sys-remote-exec
π Abstract:
Have you ever needed to debug a live Python process but couldn't restart it? Didn't want to redeploy with debug flags or manage sidecar containers just to debug your application?
In this talk, I'll show you why `sys.remote_exec()` is one of the coolest features of Python 3.14! I'll cover the basics of Python's new remote debugging capabilities and demonstrate how `sys.remote_exec()` can be combined with debugpy (an implementation of the Debug Adapter Protocol) to provide full IDE debugging experiences for live processes. I'll share what I learned building a tool that uses these primitives to attach debuggers to FastAPI applications running in local Kubernetes clusters.
Beyond debugging, we'll explore other use cases for `sys.remote_exec()` and how you can apply the feature to solve problems in your own work!
