Isn't this a duplicate of #685? |
|
It might be, I don't really understand whether or not it's exactly the same. |
|
I think it probably at least stems from the same issue which I intend to fix for the next release. |

Thanks! That would be awesome. Feel free to close this or copy over the snippet as an additional test case if you prefer that. |

Consider this snippet:
Here we spawn a task using
TaskGroup.start()then we cancel the.start()call usingmove_on_after. It turns out this cancels the task group as a whole.I'd expect this to cancel only that particular task.
For the
triobackend, this works fine, and does not cancel the task group.How can we reproduce the bug?
(see snippet above)
