> Mesos containerizer helper function signalSafeWriteStatus is not AS-Safe
> ------------------------------------------------------------------------
>
> Key: MESOS-6428
> URL: https://issues.apache.org/jira/browse/MESOS-6428
> Project: Mesos
> Issue Type: Bug
> Components: containerization
> Affects Versions: 1.1.0
> Reporter: Benjamin Bannier
> Assignee: Andrei Budnik
> Labels: newbie, tech-debt
> Fix For: 1.5.0
>
>
> In {{src/slave/containerizer/mesos/launch.cpp}} a helper function
> {{signalSafeWriteStatus}} is defined. Its name seems to suggest that this
> function is safe to call in e.g., signal handlers, and it is used in this
> file's {{signalHandler}} for exactly that purpose.
> Currently this function is not AS-Safe since it e.g., allocates memory via
> construction of {{string}} instances, and might destructively modify
> {{errno}}.
> We should clean up this function to be in fact AS-Safe.
