---------------------------------------
Summary: Resource usage calculation in docker containerizer can
race with container destruction
Key: MESOS-8465
URL: https://issues.apache.org/jira/browse/MESOS-8465
Project: Mesos
Issue Type: Bug
Components: containerization, docker
Affects Versions: 1.5.0
Reporter: Benjamin Bannier
The implementation of {{DockerContainerizerProcess::usage}} checks on the
top-level whether the container is in {{DESTROYING}} state and returns a
failure in that case. It then possibly triggers compuation of the container
pid, and {{defers}} calculating the usage on that pid. The defered calculation
only makes sure that the container is not already destroyed.
If a user triggers first requests the usage and then triggers container
destruction, {{usage}} could find the container not in {{DESTROYING}} state and
would then {{defer}} the usage computation. If the {{destroy}} is processed not
it would trigger the actual killing of the container and mark the container as
{{DESTROYING}}. If the container is not destroyed when the deferred usage
calculation could then pick up results not corresponding to the container
anymore.
