What type of PR is this?
/kind bug
What this PR does / why we need it:
I think the retain condition in
ChildReaper::forget_grandchild
was flipped.The function passed to retain specifies which elements to keep, but the specified condition returned which element we want to remove. (docs)
That results in the removal of all
grandchildren
except the one we want to forget.Which issue(s) this PR fixes:
None
Special notes for your reviewer:
I assume that the
forget_grandchild
function should remove the grandchild withpid == grandchild_pid
and not keep it.There could be existing use cases that depend on the fact, that the ChildReaper forgot the wrong grandchildren by accident.
I'm not sure, but it could be the case that conmon-rs didn't terminate spawned childs on exit because of this and will do this now. This could be a braking change? If this is the case, we should mention it in the release note block below.
Does this PR introduce a user-facing change?
