What crate(s) in this repo are involved in the problem?

tokio-console

What is the issue?

When stopping, and then re-starting tokio-console, a number of idle tasks are dropped from the task list, in situations where the task list is in a steady-state, and not changing.

I made a video to show what is happening, it seems like it might be a bug or something, I am not sure.

How can the bug be reproduced?

This repo creates two WebRTC engines: https://github.com/cameronelliott/webrtc-futures-leak

It has three stdin new-line prompts to allow entering the three states of the program:

press enter once - start webrtc stuff press enter again - close both webrtc engines press enter again - webrtc engines go out of scope

Logs, error output, etc

No response

Versions

├── console-subscriber v0.1.6 │ ├── console-api v0.3.0

Possible solution

Don't know

Additional context

Possibly lack of understanding of how console works on my part.

Would you like to work on fixing this bug?

maybe

Thanks, I watched the video you've attached, and this definitely seems like a bug to me. I'm assuming that shutting down the WebRTC engines caused a number of those tasks to terminate, but this wasn't reflected in the console that was already connected for some reason. The newly connected console seems to have displayed the actual correct state.

I'm not sure what's going on here, and I've never seen this happen before, so it definitely seems like something we should investigate.

Out of interest, I notice that you included the version numbers for console-subscriber and console-api in the report. What version is the tokio-console command line application? You can access that by running tokio-console --version.

Hi! I reproed this on my end too (after chatting with @cameronelliott yesterday) – again using webrtc-rs, but a completely different implementation than the above repo.

My version is tokio-console 0.1.6

I just checked, my version is also tokio-console 0.1.6

Great, thanks for checking.
