Stuck while trying to create the session

[fallard84]

Describe the bug you encountered:

When deploying my python app on Heroku, no profile is being sent to the Pyroscope server. The same implementation works fine when running locally with the same version of pyroscope and python.

When enabling the logs, I can only see the following every 10secs, without any error or warning:

Pyroscope::Session          > Creating Session`

What did you expect to happen instead?

Profiles should be generated and sent to the Pyroscope server.

How did you install pyroscope-rs?

Pyroscope-rs is installed through the python package:

poetry add pyroscope-io

pyroscope-rs version and environment

Latest version of pyroscope-io is installed (0.8.8) with python 3.12.6.

Apparently Heroku blocks ptrace(), which from what I understand is required by py_spy. So this is not a problem with this project.

I would argue it is a problem. It should be possible to profile apps without ptrace and I would say it should be the default mode. Therefore reopening. Not planning to work on this any time soon, but it should happen some time
