ProfilingPanel info not collected

[jheld]

In my usage the ProfilingPanel info is not being collected/processed, despite being enabled.

I have run in debug mode and the piece that looks most suspicious (in generate_stats) is that:

root_func = self.stats.get_root_func()

is returning a falsey root_func.

python3.6, django 2.2.6, and django debug toolbar 2.0

Do you have anything installed that might be impacting pstats.Stats?

[jheld]

I'll check, but can you provide more information about what to look for?

[tim-schilling]

Any other debugging packages installed or any debugging monkey patching that you've done. Perhaps try seeing if you can spin up a new project (or use DDT's example project after pulling it) to see if you can use the ProfilingPanel there.

[jheld]

For the former, we did (in some cases) have request_profiler in the stack. But I've removed it for the test. Still not working.

Not sure about any monkey patching going on.

[tim-schilling]

Are you able to use the pstats.Stats class?

[jheld]

Good news is that the example does work.

@tim-schilling where might I try using that stats class? python shell or somewhere else? Do you have a snippet I could run?

[tim-schilling]

Run the shell with your django application so the stack should be similar. Though obviously it won't eliminate everything from your stack because running the application is still different than the shell.

This script from the docs should generate a stats class internally.

import cProfile
with cProfile.Profile() as pr:
    # ... do something ...
pr.print_stats()

[jheld]

I was able to run that (using .enable and disable because the context manager didn't work).

Sorry, I don't have an answer for you. I can't reproduce this problem.
